§ 68-2 Intent, purpose and goals.

[Reference: Natural Resources Article §§ 8-1801 and 8-1808.]

Intent. In 1984, the Maryland General Assembly passed the Chesapeake Bay Critical Area Act in response to growing concern over the decline of the quality and productivity of the waters of the Chesapeake Bay and its tributaries. The decline was found to have resulted, in part, from the cumulative effects of human activity that caused increased levels of pollutants, nutrients, and toxins, and also from declines in protective land uses such as forest land and agricultural land in the Bay region. In 2002, the Atlantic Coastal Bays were added to the Critical Area because these bays were experiencing a similar decline.

Purpose. The General Assembly enacted the Critical Area Act for the following purposes:

To establish a resource protection program for the Chesapeake Bay and Atlantic Coastal Bays and their tributaries by fostering more sensitive development activity for certain shoreline areas so as to minimize impacts to water quality and natural habitats; and

To implement a resource protection program on a cooperative basis between the State and affected local governments, with local governments establishing and implementing their programs in a consistent and uniform manner subject to State Criteria and oversight.

Goals. The goals of the Critical Area Program are to accomplish the following:

Minimize adverse impacts on water quality that result from pollutants that are discharged from structures or run off from surrounding lands;

Conserve fish, wildlife, and plant habitat; and

Establish land use policies for development in the Critical Area which accommodate growth as well as address the environmental impacts that the number, movement, and activities of people may have on the area.

§ 68-3 Implementation of the Critical Area provisions.

[Reference: Natural Resources Article § 8-1808, Program Development.]

Local implementation. These provisions regulate development activities and resource utilization activities, e.g., agriculture and forestry, within the Critical Area. They supplement existing land use regulations by imposing specific standards and requirements as set forth in the Critical Area Act and Criteria. The Critical Area provisions as set forth herein and in any other applicable regulations supersede any inconsistent law, chapter, or plan of the County. In the case of conflicting provisions, the stricter provisions shall apply.

Critical Area Program. The County adopted its Critical Area Program on August 23, 1988. The program consists of this chapter, the County's Comprehensive Plan, the County's Critical Area maps, and the County's zoning, grading, erosion and sediment control and subdivision regulations.[1]

Editor's Note: See Ch. 155, Zoning; Ch. 100, Grading, Erosion and Sediment Control; and Ch. 140, Subdivision Regulations, respectively.

Regulated activities and applicability. Any applicant for a permit or license to pursue activities within the Critical Area, including but not limited to development or redevelopment, grading, sediment and erosion control, timber harvesting, shoreline erosion control, installation of a septic system and drain field, operation of a waste collection or disposal facility, operation of a commercial or private marina or other water-related commercial or industrial operation (whether public or private), mining (whether surface or subsurface) or quarrying, farming or other agriculture-related activities shall have such permits or licenses issued by the Director or designee after review and approval under the County's Critical Area Program.

Notification of project applications. [Reference: COMAR 27.03.01.]

The County shall send copies of applications for all developments, subdivisions, and site plans wholly or partially within the Critical Area to the Critical Area Commission for review and comment. The application shall be accompanied by a completed "Project Notification Application" form. The Critical Area Commission shall send written notification of receipt of the application before the close of the fifth business day. The County may not process an application which has been sent to the Critical Area Commission for notification until it has received notice of receipt by the Critical Area Commission. Any action by the County in violation of these procedures shall be void.

Responsible agencies. The County's Critical Area Program and all applicable provisions of this chapter shall be implemented and enforced by the appropriate agency within County government that administers primary responsibility for the respective land use or resource protection or governmental service policies impacted by the Critical Area Program. Should an infraction of the provisions contained in any law, regulation, or plan related to the County's Critical Area Program be brought to the attention of any County official, said official shall contact the Director or designee who may consult with the County Attorney to determine the proper remedial course of action. If appropriate, the Director or designee shall inform the Critical Area Commission about the infraction and any decision made regarding remedial action. The Critical Area Commission, at its discretion, may also take remedial action under the authority it is given under state law.

§ 68-4 Administrative enforcement.

[Reference: Natural Resources Article §§ 8-1808 and 8-1815.]

Applicability. The purpose of this chapter is to establish administrative enforcement procedures to identify violations, assess administrative civil penalties, and require abatement, restoration, and mitigation for violations to the County's Critical Area Program. The provisions of this chapter are in accordance with the Critical Area Act and Criteria and, as set out in any other applicable ordinances and regulations, apply throughout the Critical Area and supersede any inconsistent law, regulation, ordinance or plan of the County. In the case of conflicting provisions, the stricter provisions shall apply.

Compliance officials. These provisions shall be implemented and enforced by the Director or designee.

The Director or designee shall enforce and supervise enforcement responsibilities of this chapter.

The Director or designee shall conduct administrative reviews as set forth in this chapter, to evaluate the amount of administrative civil penalties in accordance with County regulations. Following an administrative review, the Director or designee may decrease, increase, or confirm the amount of the civil penalty. In addition, the Director or designee may modify or impose payment terms, conditions, schedules, or other requirements and may suspend all or part of any civil penalty.

The Director or designee may notify the Critical Area Commission of any violation and inform the Critical Area Commission of all actions taken to halt the violation, restore the property, and require appropriate mitigation. The Critical Area Commission, at its discretion, may also pursue its own remedial action or assist the County as provided for in State law.

Violations. [Reference: Natural Resources Article § 8-1808(c)(1)(iii)15.]

No person shall violate any provision of this chapter. Each violation that occurs and each calendar day that a violation continues shall be a separate offense. Each person who violates a provision of this chapter shall be subject to separate administrative civil penalties, abatement and restoration orders, and mitigation for each offense. Administrative civil penalties for continuing violations shall accrue without a requirement for an additional assessment, notice, or opportunity for hearing for each separate offense. If the Director or a designee shall find that any of the provisions of this chapter are being violated, the Director, or a designee, shall notify in writing the person responsible for such violation or violations indicating the nature of the violation and ordering the action necessary to correct it.

The Director or designee shall order discontinuance of illegal use of land, buildings, or structure; removal of illegal buildings, or structures or of additions, alterations, or structural changes thereto; discontinuance of any illegal work being done or shall take any other action authorized by this chapter to insure compliance with or to prevent violation of its provisions.

For the purposes of this provision, a violation shall include but not be limited to the following:

Violation of Dorchester County Critical Area Program.

Violation of Dorchester County Zoning Ordinance.

Violation of an existing Dorchester County Board of Zoning Appeals order, condition or restriction.

Violation of an existing Dorchester County Planning Commission order, condition or restriction.

Violation of Dorchester County Forest Conservation Ordinance.

Violation of Dorchester County Floodplain Management Ordinance.

Violation of Dorchester County Subdivision Ordinance.

Violation of Dorchester County Building Code Ordinance (regarding grading, erosion, and sediment control).

Violation of the Dorchester County Grading, Erosion and Sediment Control Ordinance.

(j)

Any other violation, including, but not limited to, noncompliance with any order of the Department of Planning and Zoning (DP&Z), the Department of Public Works, the Planning Commission, the Board of Zoning Appeals, or a court of competent jurisdiction, including but not limited to an order to modify or remove a structure, to perform mitigation, or to pay fines or assessed penalty fees related to a citation or other violation issued by DP&Z.

No zoning application, application to the Dorchester County Board of Zoning Appeals for administrative review, modification of an existing Board of Zoning Appeals order, special exception, variance or other application seeking action by the Board to Zoning Appeals or the Dorchester County Planning and Zoning Commission shall be accepted or shall otherwise proceed if a violation as above described shall exist upon or be related to the subject parcel until the violation is corrected or a plan has been approved permitting the application to proceed. [Reference: Natural Resources Article § 8-1808(c)(1)(iii)15.F.]

Required enforcement action. [Reference: Natural Resources Article § 8-1808(c)(4).]

If DP&Z or the Department of Public Works identifies a violation of this subtitle or any provision of the County's Critical Area ordinances or regulations, it shall take enforcement action including:

Assess administrative civil penalties as necessary to cover the costs associated with local authorities performing inspections, supervising or rendering assistance with identifying and citing the violation, issuing abatement and restoration orders, and reviewing mitigation plans and ensuring compliance with these plans;

Issue abatement, restoration, and mitigation orders as necessary to:

Stop unauthorized activity;

Restore and stabilize the site, as appropriate, to its condition prior to the violation or to a condition that provides the same water quality and habitat benefits; and

Require the implementation of mitigation measures, in addition to restoration activities, to offset the environmental damage and degradation or loss of environmental benefit resulting from the violation.

Responsible persons. [Reference: Natural Resources Article § 8-1808(c)(1)(iii)14, 15.C and (c)(2)(ii).]

The following persons may each be held jointly or severally responsible for a violation:

Persons who apply for or obtain any permit or approval;

Contractors;

Subcontractors;

Property owners;

Managing agents; or

Any person who has committed, assisted, or participated in the violation.

Administrative civil penalties. [Reference: Natural Resources Article § 8-1808(c)(1)(iii)14 and (c)(2).]

In addition to any other penalty applicable under state or County law, every violation of a provision of Natural Resources Article, Title 8, Subtitle 18, or the County's Critical Area Program, ordinance, or regulations shall be punishable by a civil penalty of up to $10,000 per calendar day.

Before imposing any civil penalty, the person(s) believed to have violated this chapter shall receive written notice of the alleged violation(s), including which, if any, are continuing violations, and an opportunity to be heard. The amount of the civil penalty for each violation, including each continuing violation, shall be determined separately. For each continuing violation, the amount of the civil penalty shall be determined per day. In determining the amount of the civil penalty, the Director or designee shall consider:

The gravity of the violation;

The presence or absence of good faith of the violator;

Any willfulness or negligence involved in the violation, including a history of prior violations;

The environmental impact of the violation; and

The cost of restoration of the resource affected by the violation and mitigation for damage to that resource, including the cost to the state or local authorities for performing, supervising, or rendering assistance to the restoration and mitigation.

When a section of this chapter establishes a different maximum amount for a civil penalty for any violation, the larger amount shall apply.

Administrative civil penalties for continuing violations shall accrue for each violation, every day each violation continues, with no requirements for additional assessments, notice, or hearings. The total amount payable for continuing violations shall be the amount assessed per day for each violation multiplied by the number of days that each violation has continued.

The person responsible for any continuing violation shall promptly provide the Director or designee with written notice of the date(s) the violation has been or will be brought into compliance and the date(s) for the County inspection to verify compliance. Administrative civil penalties for continuing violations continue to accrue as set forth herein until the County receives such written notice and verifies compliance by inspection or otherwise.

Assessment and payment of administrative civil penalties shall be in addition to and not in substitution for recovery by the County of all damages, costs, and other expenses caused by the violation, including the cost to correct any violation or repair, restore, or replace any County property.

Payment of all administrative civil penalties assessed shall be a condition precedent to the issuance of any permit or other approval required by this Code.

In this section "owner" or "property owner" includes two or more persons holding title to the property under any form of joint ownership;

In this section "person" includes the federal government, the state, any County, municipal corporation, or other political subdivision of the state, or any of their units, or an individual receiver, trustee, guardian, executor, administrator, fiduciary, or representative of any kind, or any partnership, firm, association, public or private corporation, or any other entity, including a contractor, property owner or any other person who committed, assisted, authorized or participated in a violation of Title 8, Subtitle 18, of the Annotated Code of Maryland entitled "Chesapeake and Atlantic Coastal Bays Critical Area Protection Program" or a violation of this chapter entitled "Critical Area."

The Director of Planning is hereby authorized to issue citations for civil infractions for violations of this chapter in accordance with § 147-2 of the Dorchester County Code and the amount of the civil penalty or fine to be assessed under this section. All civil penalties or fines for civil infractions under this section shall be payable to the County;

The Director of Planning is also authorized to issue with the citation for civil infractions an administrative abatement order requiring the owner, property owner or person to abate or to correct an alleged violation of this chapter, entitled "Critical Area," or to cease work or activity being performed in the Critical Area Protection District. The administrative abatement order shall be served with the citation for civil infraction pursuant to Chapter 147, § 147-2, et seq. of this Code. The administrative abatement order shall be enforced pursuant to § 147-6F(4) and G of Chapter 147 of the Dorchester County Code;

If a final adjudication of a notice of violation results in a determination that a violation has occurred, the person shall be liable to a penalty that is twice the amount of the assessment in the notice of violation, in addition to the cost of the hearing and any applicable mitigation costs; and

Application for a variance constitutes a waiver of the right to appeal the terms of a notice of violation and its final adjudication, including the payment of any penalties and costs assessed.

Notice of violations and assessment of administrative civil penalties. [Reference: Natural Resources Article § 8-1808(c)(1)(iii)14.]

Every notice of violation and assessment of civil penalty shall be in writing and shall include:

A description of the facts supporting each alleged violation;

Classification of each alleged violation as a continuing or noncontinuing violation;

Separate assessment of a civil penalty for each violation, and a separate daily assessment for each continuing violation;

Notice of the right to request administrative review before the Director or designee to evaluate the amount(s) of administrative civil penalties; and

Notice of the right to file an appeal to the Board of Zoning Appeals.

Administrative abatement, restoration, and mitigation orders. [Reference: Natural Resources Article § 8-1808(c)(1)(iii)15.]

The provisions of this chapter apply to orders issued by the Director or designee to a person conducting or having conducted an unauthorized action. Orders shall be sent to the alleged violator by certified mail, return receipt requested. Service shall be effective upon mailing. In addition, any other method of service reasonably calculated to provide actual notice, and any method that does provide actual notice, shall be sufficient, including service by personal delivery to a responsible person at any construction site or posting the order in a conspicuous place on any structure, sign, land, or equipment.

The Director or designee may issue an administrative abatement order to any person, compelling the person to perform the following:

To correct, discontinue or abate any violation;

To cease any activity being performed in violation of this chapter; and

To apply for any permit, approval, special exception, or variance required by this chapter; however, the filing of an application will not negate or stay the requirement for abatement, restoration, or mitigation measures required by the Director or designee.

The Director or designee may issue a restoration order to any person compelling the person to perform the following:

To remove any construction materials, equipment, and any structures or other construction work built or erected in violation of this chapter;

To restore any property to its condition as it existed before any violation of this chapter;

To perform any condition or obligation required by this chapter or by any permit, approval, special exception, variance, license, contract, deed, or other instrument required or executed pursuant to this chapter;

Administrative abatement and restoration orders shall be sent to the alleged violator by certified mail, return receipt requested. Service shall be effective upon mailing. In addition, any other method of service reasonably calculated to provide actual notice, and any method that does provide actual notice, shall be sufficient, including service by personal delivery to a responsible person at any construction site or posting the order in a conspicuous place on any structure, sign, land, or equipment.

The Director or designee shall issue a mitigation order to any person receiving notice of or issued a citation for conducting or having conducted an unauthorized action. Mitigation is required for all violations of the County's Critical Area Program and shall be in addition to any required abatement or restoration activities. [Reference: Natural Resources Article § 8-1808(c)(4)(ii).] In evaluating the type and amount of mitigation, the Department shall consider the severity of the impact on water resources and habitat and the length of time necessary to restore the resources to their condition prior to the violation, or if that is not possible to recreate or establish and permanently protect similar resources in another location. The mitigation order shall compel the person to perform the following:

To implement appropriate water quality improvement or habitat enhancement measures that are sufficient to offset adverse impacts to the Critical Area resulting from the violation as follows:

Mitigation is required at a three-to-one ratio for the area disturbed or the area of the development activity outside the 100-foot buffer and expanded buffer, and

Mitigation is required at a four-to-one ratio for the area disturbed or the area of the development activity within the 100-foot buffer or expanded buffer;

To prepare or to have a qualified professional prepare a mitigation plan that includes water quality improvement or habitat enhancement measures to offset adverse impacts to the Critical Area resulting from the violation as specified in Subsection H(4)(a) above; or

To pay a fee-in-lieu of mitigation that shall be deposited in a dedicated Critical Area Restoration Fund and used exclusively to conduct or facilitate activities or projects that promote the goals of the Critical Area Program and to ensure its effective implementation within the County.

Contents of administrative abatement, restoration, and mitigation orders. The provisions of this chapter apply to orders issued by the Director or designee to a person conducting or having conducted an unauthorized action. All orders shall include:

A description of each violation, including citation to the applicable County ordinance, regulation, or other requirement allegedly violated;

The time within which any required action is to occur, taking into account the specific action required to comply with the order and any existing or intervening harm or threat to the public health, safety, and welfare. Except for emergencies, which can require compliance as soon as 24 hours or otherwise less than 30 days, there is a rebuttable presumption that compliance with the orders shall take place within 30 days from the date of the order; and

Notice of the right to appeal the order to the Board of Zoning Appeals and the period within which any such appeal must be filed.

Bonding for restoration and mitigation orders. [Reference: Natural Resources Article § 8-1815.]

For abatement or restoration activities and mitigation activities that exceed 1,000 square feet or involve expenses exceeding $1,000, the Department shall:

Collect a bond or other financial security to ensure that the restoration or mitigation is properly completed;

Hold a bond for at least two years if the restoration involves planting in order to ensure the survival of the plantings. The two years will run from the date the plantings are installed; and

Schedule and perform an inspection of the property at the property owner's request as necessary to ensure compliance and promptly release the bond or other financial security when compliance is confirmed.

Cumulative remedies. [Reference: Natural Resources Article §§ 8-1808 and 8-1815.]

The remedies available to the County under this chapter are cumulative and not alternative or exclusive, and the decision to pursue one remedy does not preclude pursuit of others.

Injunctive relief. [Reference: Natural Resources Article § 8-1815.]

The Director or designee is authorized to institute injunctive or other appropriate actions or proceedings to bring about the discontinuance of any violation of this chapter, an administrative order, a permit, a decision, or other imposed condition.

The pendency of an appeal to the Board of Zoning Appeals or subsequent judicial review shall not prevent the County from seeking injunctive relief to enforce an administrative order, permit, decisions, or other imposed condition, or to restrain a violation pending the outcome of the appeal or judicial review.

In an action for injunctive relief to enforce an administrative order, the court may also impose a civil fine up to $10,000 for each day that an administrative order was violated, but not exceeding $10,000, after considering:

The willfulness for the violation;

The harm to the environment or the community in which the violation occurred; and

The cost to the County of enforcing the administrative order.

Permits pursuant to a violation. [Reference: Natural Resources Article § 8-1808(c)(4).]

The Department may not issue any permit, approval, variance, or special exception, unless the person seeking the permit has:

Fully paid all administrative, civil, or criminal penalties as set forth in Subsection F above;

Prepared a restoration or mitigation plan, approved by the Department, to abate impacts to water quality or natural resources as a result of the violation;

Performed the abatement measures in the approved plan in accordance with the local Critical Area regulations; and

Unless an extension of time is approved by the Department because of adverse planting conditions, within 90 days of the issuance of a permit, approval, variance, or special exception for the affected property, any additional mitigation required as a condition of approval for the permit, approval, variance, or special exception shall be completed.

Nonissuance, nonrenewal, suspension, or revocation of permit. The Director or designee may decline to issue or renew, or may suspend or revoke any permit or license issued under the authority of, or required by this chapter.

Such action may be taken on the following grounds:

False, misleading, inaccurate, incomplete, or incorrect information given on any application; or

Serious or repeated violations of this chapter, or any terms, conditions, or restrictions in the permit or license itself.

The Director or designee shall give written notice and opportunity to be heard before any nonissuance, nonrenewal, suspension, or revocation and shall render a written decision on the matter, which shall be considered an administrative order and may be appealed to the Board of Zoning Appeals.

Enforcement costs. [Reference: Natural Resources Article § 8-1815.]

In any action or proceeding in which the County substantially prevails, the County may recover all costs incurred to enforce the terms of this chapter, including counsel fees and litigation expenses.

Appeals. An appeal to the County Board of Zoning Appeals may be filed by any person aggrieved by any order, requirement, decision or determination by the Director or designee in connection with the administration and enforcement of this chapter.

§ 68-5 Development in Critical Area.

[Reference: COMAR 27.01.02.01 through .02 and Natural Resources Article § 8-1808.]

Description. The provisions of this chapter apply generally to all development, redevelopment and development activities throughout the Critical Area, except where specifically noted.

General policies. In order to accommodate already existing land uses and growth in the County Critical Area while providing for the conservation of habitat and the protection of water quality, the County has identified and mapped three land use management districts within the Critical Area. The Critical Area has also been defined as an overlay zone in the County Zoning Ordinance. The County has identified each of the three land use management districts within the Critical Area based on the following criteria and has developed policies and programs to achieve the objectives as proposed by the County program. The County recognizes the following three types of development areas: intensely developed areas (IDAs); limited development areas (LDAs); and resource conservation areas (RCAs). The following general provisions are applicable throughout the Critical Area:

Intense development should be directed outside of the Critical Area. Future intense development activities, when proposed in the Critical Area, shall be directed towards the intensely developed areas.

Additional low-intensity development may be permitted in the limited development areas but shall be subject to strict regulation to prevent adverse impacts on habitat and water quality.

Development shall be limited in the resource conservation area, which shall be chiefly designated for agriculture, forestry, fisheries activities, and other resource utilization activities and for habitat protection.

Permitted uses by zoning district. The Table of Permitted Uses by Zoning District, in § 155-34B(1), is hereby adopted by reference as part of this chapter.[1]

Editor's Note: See Ch. 155, Zoning, Attachment 1.

Implementation. For purposes of implementing this regulation the County has determined, based on land uses and development in existence on December 1, 1985, which land areas fall within the three types of land management and development areas described in this program.

Activities not permitted except in IDA. Certain new development, redevelopment or expanded activities or facilities, because of their intrinsic nature or because of their potential for adversely affecting habitats or water quality, may not be permitted in the Critical Area except in intensely developed areas under regulations of this chapter and only after the activity or facility has demonstrated to all appropriate local and state permitting agencies that there will be a net improvement in water quality to the adjacent body of water. These activities include the following:

Nonmaritime heavy industry;

Transportation facilities and utility transmission facilities, except those necessary to serve permitted uses, or where regional or interstate facilities must cross tidal waters (utility transmission facilities do not include power plants); or

Permanent sludge handling, storage and disposal facilities, other than those associated with wastewater treatment facilities. However, agricultural or horticultural use of sludge under appropriate approvals when applied by an approved method at approved application rates may be permitted in the Critical Area, except in the 100-foot buffer.

The County may preclude additional development activities that it considers detrimental to water quality or fish, wildlife, or plant habitats within the Critical Area.

Activities not permitted. Certain new development activities or facilities, or the expansion of certain existing facilities, because of their intrinsic nature or because of their potential for adversely affecting habitat and water quality, may not be permitted in the Critical Area unless no environmentally acceptable alternative exists outside the Critical Area, and these development activities or facilities are needed in order to correct an existing water quality or wastewater management problem. These include:

Solid or hazardous waste collection or disposal facilities, including transfer stations; or

Sanitary landfills.

Continuation of existing, permitted facilities. Existing, permitted facilities of the type noted in Subsection E above shall be subject to the standards and requirements of the Department of the Environment, under COMAR Title 26.

Reasonable accommodations for the needs of disabled citizens. The Board of Zoning Appeals may make reasonable accommodations to avoid discrimination on the basis of a physical disability. Reasonable accommodations for the needs of disabled citizens may be permitted in accordance with the evidentiary requirements set forth in the following paragraphs.

An applicant shall have the burden of demonstrating by a preponderance of evidence that:

The alterations will benefit persons with a disability within the meaning of the Americans With Disabilities Act;

Literal enforcement of the requirements of this chapter would result in discrimination by virtue of such disability or deprive a disabled resident or user of the reasonable use and enjoyment of the property;

A reasonable accommodation would reduce or eliminate the discriminatory effect of the requirements or restore the disabled resident's or user's reasonable use or enjoyment of the property;

The accommodation requested will not substantially impair the purpose, intent, or effect of the provisions of this chapter as applied to the property; and

The accommodation would:

Be environmentally neutral with no greater negative impact on the environment than the literal enforcement of the statute, ordinance, regulation or other requirement; or

Allow only the minimum environmental changes necessary to address the needs resulting from the particular disability of the applicant/appellant.

The Board of Zoning Appeals shall determine the nature and scope of accommodation under this subsection and may award different or other relief than requested after giving due regard to:

The standards given in this subsection;

The purpose, intent, or effect of the requirements from which relief is requested; and

The size, location, nature, and type of accommodation proposed and whether alternatives exist which could accommodate the need with less adverse effect.

The Board of Zoning Appeals may require, as a condition of approval, that upon termination of the need for accommodation, that the property be restored to comply with all applicable provisions of this chapter. Appropriate bonds may be collected or liens placed in order to ensure the County's ability to restore the property should the applicant fail to do so.

Reasonable accommodations for emergency services. The Board of Appeals may make reasonable accommodations, on the basis of public need, for development and redevelopment in the buffer for emergency services. Reasonable accommodations may be permitted in accordance with the evidentiary requirements set forth in the following subsections:

An applicant shall have the burden of demonstrating the following:

The existence of a public need.

Literal enforcement of the provisions of this subsection would result in diminished or inadequate emergency services provided to the local community.

Without a reasonable accommodation, the provisions of this subsection would prohibit adequate emergency services in the local community.

The accommodation requested will not substantially impair the purpose, intent, or effect of the provisions of this subsection as applied to the property.

Environmental impacts associated with the accommodation are the minimum necessary to provide adequate emergency services to the local community.

The Board of Appeals shall determine the nature and scope of any accommodation under this subsection and may award different or other relief than that requested after giving due regard to the purpose, intent, or effect of the applicable provisions of this subsection. The Board may also consider the size, location, and type of accommodation proposed and whether alternatives exist which accommodate the need with less adverse effect.

The Board of Appeals shall require 3:1 mitigation as a condition of variance approval for requests regarding emergency services.

§ 68-6 Intensely developed areas.

[Reference: COMAR 27.01.02.03.]

Description: areas where residential, commercial, institutional, and/or industrial developed uses predominate and where relatively little natural habitat occurs. At the time of the initial mapping, these areas shall have had at least one of the following features:

Housing density equal to or greater than four dwelling units per acre;

Industrial, institutional or commercial uses are concentrated in the area; or

Public sewer and water collection and distribution systems are currently serving the area and housing density is greater than three dwelling units per acre;

Additional requirements. In addition, these features shall be concentrated in an area of at least 20 adjacent acres or that entire upland portion of the Critical Area within the boundary of a municipality, whichever is less.

General policies. The Critical Area Ordinance for Dorchester County hereby incorporates the following policies for intensely developed areas. New or expanded development or redevelopment shall take place in such a way as to:

Improve the quality of runoff from developed areas that enters the Chesapeake Bay or its tributary streams;

Accommodate additional development of the type and intensity designated by the County in this program, provided that water quality is not impaired;

Minimize the expansion of intensely developed areas into portions of the Critical Area designated as habitat protection areas and resource conservation areas under this program;

Conserve and enhance fish, wildlife, and plant habitats, as identified in the habitat protection area sections of this chapter, to the extent possible within intensely developed areas; and

Encourage the use of retrofitting measures to address existing stormwater management problems.

Development standards. The following criteria are hereby adopted for intensely developed areas:

All development plans shall be assessed for their impacts on water quality and other biological resources;

For redevelopment plans, opportunities to reduce impacts on water quality generated by existing development shall be analyzed;

A part of all plans for development and redevelopment, urban best management practices shall be considered and, where appropriate, implemented;

Development and redevelopment shall be subject to the habitat protection area requirements prescribed in those sections of this chapter;

All roads, bridges, and utilities are prohibited in a habitat protection area, unless no feasible alternative exists. If a road, bridge or utility is authorized the design, construction, and maintenance shall:

Provide maximum erosion protection;

Minimize negative impact on wildlife, aquatic life, and their habitats; and

Maintain hydrologic process and water quality.

All development activities that must cross or affect streams shall be designed to:

Reduce increases in flood frequency and severity that are attributable to development;

Retain tree canopy so as to maintain stream water temperature within normal variation;

Provide a natural substrate for stream beds; and

Minimize adverse water quality and quantity impacts of stormwater.

Stormwater shall be addressed in accordance with the following provisions:

The County shall require, at the time of development or redevelopment, that technologies as required by applicable state and local ordinances be applied by anyone undertaking development activities in order to minimize adverse impacts to water quality caused by stormwater.

In the case of redevelopment, if these technologies do not reduce pollutant loadings measured by use of the keystone pollutant method by at least 10% below the level of pollution on the site prior to redevelopment, then offsets shall be provided. Guidance for compliance with this requirement is provided in the Critical Area 10% Rule Guidance Manual - Fall 2003, and as may be subsequently amended.

In the case of new development, offsets as determined by the County shall be used if they reduce pollutant loadings by at least 10% of the predevelopment levels. Guidance for compliance with this requirement is provided in the Maryland Chesapeake and Atlantic Coastal Bays Critical Area 10% Rule Guidance - Fall 2003, and as may be subsequently amended.

Offsets may be provided either on or off site, provided that water quality benefits are equivalent, that the benefits are obtained within the same watershed, and that the benefits can be determined through the use of modeling, monitoring or other computation of mitigation measures. Guidance regarding offsets is provided in the Maryland Chesapeake and Atlantic Coastal Bays Critical Area 10% Rule Guidance - Fall 2003.

If practicable, permeable areas shall be established in vegetation and whenever possible, redevelopment shall reduce existing levels of pollution.

Areas of public access to the shoreline, such as foot paths, scenic drives and other public recreational facilities, should be maintained and, if possible, encouraged to be established within intensely developed areas.

Ports and industries which use water for transportation and derive economic benefits from shore access shall be located near existing port facilities. The County may identify other sites for planned future port facility development and use if this use will provide significant economic benefit to the state or County and is consistent with the provisions of the water-dependent facilities section of this chapter[1] and other state and federal regulations.

Editor's Note: See § 68-19, Water-dependent facilities.

The County shall promote, with the assistance from state agencies, participation in programs and activities for the enhancement of biological resources within the Critical Area for their positive effects on water quality and urban wildlife habitat. These programs may include urban forestry, landscaping, gardens, wetland and aquatic habitat restoration elements.

To the extent practicable, future development in the Critical Area shall use cluster development as a means to reduce impervious areas and to maximize areas of natural vegetation.

When the cutting or clearing of trees in forests and developed woodland areas is associated with current or planned development activities, the following shall be required:

Participation in programs established by the County for the enhancement of forest and developed woodland resources, such as programs for urban forestry that involve street tree plantings, gardens, landscaping, and open land buffer plantings;

Development activities shall be designed and implemented to minimize destruction of forest and woodland vegetation; and

Development activities shall address the protection of existing forests and developed woodlands identified as habitat protection areas in the applicable sections of this chapter.

§ 68-7 Limited development areas.

[Reference: COMAR 27.01.02.04.]

Description. Limited development areas are those areas in which are currently developed low- or moderate-intensity uses. They also contain areas of natural plant and animal habitats. The quality of runoff from these areas has not been substantially altered or impaired. At the time of the initial mapping, these areas shall have had at least one of the following features:

Housing density ranging from one dwelling unit per five acres up to four dwelling units per acre;

Areas not dominated by agricultural, wetland, forest, barren land, surface water, or open space;

Areas meeting the conditions of intensely developed area but comprising less than 20 acres;

Areas having public sewer or public water, or both.

General policies. The County's Critical Area Ordinance hereby incorporates the following policies for limited development areas. New or expanded development or redevelopment shall take place in such a way as to:

Maintain or, if possible, improve the quality of runoff and groundwater entering the Chesapeake Bay and its tributaries;

Maintain, to the extent practicable, existing areas of natural habitat; and

Accommodate additional low- or moderate-intensity development if:

This development conforms to the water quality and habitat protection criteria in Subsection C below; and

The overall intensity of development within the limited development area is not increased beyond the level established in a particular area so as to change its prevailing character as identified by density and land use currently established in the area.

Development standards. For all development activities in the limited development areas, the County shall require that the applicant identify any environmental or natural feature described below, and shall meet all of the following standards of environmental protection:

Adherence to the provisions of the applicable sections of this chapter regarding habitat protection areas and water-dependent facilities;

Provide maximum erosion protection;

Minimize negative impact on wildlife, aquatic life, and their habitats; and

Maintain hydrologic process and water quality.

All development activities that must cross or affect streams shall be designed to:

Reduce increases in flood frequency and severity that are attributable to development;

Retain tree canopy so as to maintain stream water temperature within normal variation;

Provide a natural substrate for stream beds; and

Minimize adverse water quality and quantity impacts of stormwater.

All development sites shall incorporate a wildlife corridor system that connects the largest undeveloped or most vegetative tracts of land within and adjacent to the site in order to provide continuity of existing wildlife and plant habitats with off-site habitats. The wildlife corridor system may include habitat protection areas identified in this chapter. The County shall ensure the maintenance of the wildlife corridors by requiring the establishment of conservation easements, restrictive covenants, or similar instruments approved by the County Attorney through which the corridor is preserved by public or private groups, including homeowners' associations, nature trusts and other organizations.

For the cutting or clearing of trees in forests and developed woodland areas which are associated with current or planned development activities in a limited development area, the County shall:

Require that the applicant consider the recommendations of the Maryland Department of Natural Resources when planning development on forested land;

Design and implement development activities to minimize the destruction of woodland vegetation; and

Provide protection for forests and developed woodlands identified as habitat protection areas in this program.

For the alteration of forest and developed woodland in the limited development area, the County shall apply all of the following requirements:

The total acreage in forest coverage within the County in the Critical Area shall be maintained or preferably increased;

All forests that are allowed to be cleared or developed shall be replaced in the Critical Area on not less than an equal area basis;

If a developer is authorized to clear more than 20% of a forest or developed woodlands on a lot or parcel, the developer shall replace the forest or developed woodlands at 1.5 times the areal extent of the forest or developed woodlands cleared, including the first 20% of the forest or developed woodlands cleared;

A developer may not clear more than 30% of a forest or developed woodlands on a lot or parcel, unless the County:

Authorizes the removal of more than 30% by the granting of a variance; or

Adopts procedures for the removal of more than 30% of a forest or developed woodland and the Commission has approved those procedures as part of a local program; and

If a developer is authorized to clear any percentage of forest or developed woodlands from forest use under Subsection C(6) of this regulation, the remaining percentage shall be maintained through recorded, restrictive covenants or similar instruments.

Clearing in excess of 30% of an existing forest or developed woodland is prohibited without a variance.

In addition, applicants shall adhere to the following criteria for forest and woodland development:

Grading permits shall be required before forest or developed woodland is cleared;

Forests which have been cleared before obtaining a grading permit or that exceed the maximum area allowed in Subsection C(7) above shall be replanted at three times the areal extent of the cleared forest;

If no forest is established on proposed development sites, these sites shall be planted to provide a forest or developed woodland cover of at least 15%;

All forests designated on development plans shall be maintained to the extent practicable, through conservation easements, restrictive covenants or other protective instruments approved by the County Attorney;

The applicant shall designate, subject to the approval of the County, a new forest area on a part of the site not forested; and

The afforested area shall be maintained as forest cover through easements, restrictive covenants or other protective instruments approved by the County Attorney.

Applicants shall adhere to the following standards for development on steep slopes. Development on slopes greater than 15%, as measured before development, shall be prohibited unless the project is the only effective way to maintain or improve the stability of the slope and is consistent with the policies and standards for limited development areas set forth above.

Except as otherwise provided in this subsection, for stormwater runoff, lot coverage shall be limited to 15% of the site. [Reference: Natural Resources Article 8-1808.3.] This section does not apply to agricultural uses and structures in use for agricultural purposes on parcels with approved soil conservation and water quality plans or erosion and sediment control plans approved by the Soil Conservation District. Structures which qualify as water-dependent facilities do not require a variance; however, they must still meet the lot coverage limits.

If a parcel or lot of 1/2 acre or less in size existed on or before December 1, 1985, then lot coverage is limited to 25% of the parcel or lot.

If a parcel or lot greater than 1/2 acre and less than one acre in size existed on or before December 1, 1985, then lot coverage is limited to 15% of the parcel or lot.

If an individual lot one acre or less in size is part of a subdivision approved after December 1, 1985, then lot coverage may exceed 15% of the individual lot; however, the total lot coverage for the entire subdivision may not exceed 15%.

This section does not apply to a trailer park that was in residential use on or before December 1, 1985.

Lot coverage limits provided in Subsection C(10)(a) and (b) above may be exceeded, upon findings by the Planning Director or his designee that the following conditions exist:

Lot coverage associated with new development activities on the property have been minimized;

For a lot or parcel 1/2 acre or less in size, total lot coverage does not exceed 31.25% or 25% plus 500 square feet, whichever is greater;

For a lot or parcel greater than 1/2 acre and less than one acre in size, total lot coverage does not exceed 15% or 5,445 square feet, whichever is greater;

Water quality impacts associated with runoff from new development activities that contribute to lot coverage can be and have been minimized through site design considerations or use of best management practices approved by the County to improve water quality; and

The property owner performs on-site mitigation as required by the County to offset potential adverse water quality impacts from the new development activities that contribute to lot coverage, or the property owner pays a fee to the County in lieu of performing the on-site mitigation.

[6]

All fees collected by the County under Subsection C(10)(e)[5], above, of this section must be used to fund projects that improve water quality within the Critical Area consistent with the County's Critical Area Protection Program.

[7]

The following table summarizes the limits set forth in Subsection C(10)(a) through (c) above:

Table 68-7C(10)(e)
Lot Coverage Limits
Lot/Parcel Size (square feet)	Lot Coverage Limit
0 - 8,000	25% of parcel + 500 square feet
8,001 - 21,780	31.25% of parcel
21,781 - 36,300	5,445 square feet
36,301 - 43,560	15% of parcel

If the Planning Director or his designee makes the findings set forth in Subsection C(10)(e) above and authorizes an applicant to use the lot coverage limits set forth in that paragraph, the applicant shall:

Demonstrate that water quality impacts associated with runoff from the development activities that contribute to lot coverage have been minimized through site design considerations or the use of best management practices to improve water quality; and

Provide on-site mitigation in the form of plantings to offset potential adverse water quality impacts from the development activities resulting in new lot coverage. The plantings shall be equal to two times the area of the development activity.

If the applicant cannot provide appropriate stormwater treatment and plantings due to site constraints, then the County may require the property owner to pay a fee to the County in lieu of performing the on-site mitigation. The amount of the fee shall be $1 per square foot of the required mitigation. The County shall use all fees collected under this provision to fund projects that improve water quality within the Critical Area, consistent with the County's Critical Area Program and Zoning Ordinance.

Lot coverage exchange.

A lot coverage exchange may be conducted on a lot that exceeds the lot coverage limits of Subsection C(10)(e). A property owner may remove existing lot coverage in exchange for new lot coverage under the following circumstances:

The existing lot coverage on site shall be legally grandfathered or permitted by the Planning and Zoning Office;

No more than 500 square feet of lot coverage will be exchanged;

There will be no net increase in lot coverage on site;

The removal of lot coverage outside of the buffer will not be used to accommodate new lot coverage in the buffer;

[e]

In no case shall redevelopment increase any nonconformity on site.

[f]

Mitigation is required at a ratio of 1:1 for the square footage of exchanged lot coverage.

In the instance where a lot exceeds its lot coverage limit, a property owner may remove existing lot coverage in the buffer in exchange for new lot coverage in the buffer under the following circumstances:

The applicant receives a variance in accordance with § 68-16.

The existing lot coverage on site shall be legally grandfathered or permitted by the Planning and Zoning Office;

No more than 500 square feet of existing lot coverage in the buffer or expanded buffer shall be exchanged for new lot coverage in the buffer or expanded buffer;

Lot coverage in the expanded buffer may not be exchanged for new lot coverage in the 100-foot buffer.

[e]

There will be no net increase of lot coverage on site;

[f]

There will be no net increase of lot coverage within the buffer or expanded buffer;

[g]

Mitigation shall be provided for disturbance in the buffer as required under the variance provisions in § 68-16.

A fee-in-lieu shall be provided to the County if the area of the site precludes the implementation of on-site mitigation. The amount of the fee shall be determined by the Director or his designated representative. All moneys collected will be retained in the Critical Area Forest Replacement Fund.

A lot or parcel legally developed as of July 1, 2008, may be considered legally nonconforming for the purposes of lot coverage requirements. For the purpose of increasing lot coverage on these parcels, the lot coverage limitations may not be construed to apply to a development activity for which a building permit was issued before July 1, 2008, and construction was initiated and an inspection was performed before July 1, 2009.

Lot coverage on a parcel is limited in accordance with the following maximums:

[Reference: COMAR 27.01.02.04.]

When a site is mapped entirely as a limited development area: 15% of the total site;

When a portion of a lot or parcel is mapped as a limited development area: 15% of that portion of the lot or parcel; and

In the case of a growth allocation award:

Fifteen percent of the growth allocation development envelope; or

Fifteen percent of the acreage proposed for growth allocation deduction.

Dorchester County shall allow for modifications in road standards to reduce potential impact to the site and Critical Area resources, where the reduced standards do not significantly affect safety.

Development may be allowed on soils having development constraints if it includes mitigation measures that adequately address the identified constraints and that will not have significant adverse impacts on water quality or plant, fish, or wildlife habitat.

Complementary state laws and regulations. In applying this Critical Area Program, the County refers to all of the following complementary existing state laws and regulations:

For soil erosion and sediment control (COMAR 26.17.01):

In order to prevent soil erosion and sedimentation, a Soil Erosion and Sedimentation Control Plan shall be required whenever a development within the Critical Area will involve any clearing, grading, transporting, or other form of disturbance to land by the movement of earth. This plan shall be consistent with the requirements of the Natural Resources Article and Environment Article of the Annotated Code of Maryland and local ordinances. Sediment control practices shall be appropriately designed to reduce adverse water quality impacts.

For stormwater runoff (COMAR 26.17.02):

The County requires limitations on stormwater runoff are consistent with the requirements contained in COMAR 26.17.02.

The County requires that applicants for development ensure that all stormwater storage facilities shall be designed with sufficient capacity to achieve water quality goals of this section and to eliminate all runoff caused by the development in excess of that which would have come from the site if it were in its predevelopment state.

Stormwater management measures shall be consistent with the requirements of Environment Article 4-201 et seq., Annotated Code of Maryland.

Development activities on individual lots within subdivisions recorded prior to adoption of the provisions in COMAR 26.17.02 shall provide stormwater quantity and quality management unless:

The project is an addition or modification to an existing single-family dwelling;

The project involves disturbance that does not exceed 5,000 square feet; or

The project is otherwise regulated under other state laws that include provisions for managing stormwater runoff.

§ 68-8 Resource conservation areas.

[Reference: COMAR 27.01.02.05.]

Description. Resource conservation areas are those areas characterized by nature-dominated environments (that is wetlands, forests, abandoned fields) and resource-utilization activities (that is agriculture, forestry, fisheries activities or aquaculture). At the time of the initial mapping, these areas shall have had at least one of the following features:

Existing density is less than one dwelling unit per five acres; or

Dominant land use is in agriculture, wetland, forest, barren land, surface water or open space.

General policies. The County's Critical Area Ordinance hereby incorporates the following policies for resource conservation areas. New or expanded development or redevelopment in these areas shall take place in such a way as to:

Conserve, protect and enhance the overall ecological values of the Critical Area, its biological productivity and its diversity;

Provide adequate breeding, feeding and wintering habitats for those wildlife populations that require the Chesapeake Bay, the Atlantic Coastal Bays, their tributaries or coastal habitats in order to sustain populations of those species;

Conserve the land and water resource base that is necessary to maintain and support land uses such as agriculture, forestry, fisheries activities and aquaculture; and

Conserve the existing developed woodlands and forests for the water quality benefits that they provide.

Development standards. In implementing this Critical Area Ordinance, the County shall use all of the following requirements for resource conservation areas:

Additional low-intensity residential development is allowed in resource conservation areas, subject to the land use and other regulations applicable to the underlying zoning district. Residential uses shall not exceed an overall density of one dwelling unit per 20 acres.

In calculating the allowable residential development density for a parcel within a resource conservation area, the area of any private tidal wetlands located on the property may be included. However, the area of private tidal wetlands must be estimated on the basis of vegetative information as designated on the state wetland maps, and the development density on the upland portion of the parcel may not exceed one dwelling unit per eight acres.

Commercial, institutional, industrial, and agricultural facilities in the resource conservation area shall be as follows:

Existing industrial, institutional, commercial and agricultural facilities, including those directly supporting agriculture, forestry, aquaculture, or residential development [not exceeding the density specified in § 68-8C(1) above shall be allowed to continue in RCAs.

Except as provided by § 68-12, additional land in the RCA may not be zoned for industrial, institutional, or commercial development.

New commercial, industrial or institutional uses in existing structures may be allowed where the underlying zoning classification permits, provided:

The existing structure or structures housed a commercial, industrial or institutional use and such commercial, industrial or institutional use has not been abandoned for more than one year; and

The proposed new use does not constitute an intensification or expansion of the preexisting commercial, industrial or institutional use.

Intensification or expansion of existing industrial, commercial, and institutional facilities and uses may be permitted in the RCA by the Planning Commission. A variance, in accordance with § 68-16 must be granted if such expansion or intensification involves a use which the Planning Commission determines does not conform with the provisions of the Dorchester County Critical Area Program and the Critical Area Overlay Zone.

Nonresidential uses permitted without growth allocation. The following nonresidential uses may be permitted in resource conservation areas without obtaining growth allocation:

Nonresidential uses permitted in RCA Districts on the Table of Permitted Uses by Zoning District.[1]

Editor's Note: See Ch. 155, Zoning, Attachment 1.

An accessory or supportive use clearly incidental to an existing industrial and commercial facility, including those that directly support agriculture, forestry, aquaculture, or residential development, and which is located wholly within an existing structure or structures. Any expansion of existing structures may only be approved with future growth allocation.

A use that will be completely housed in an existing building or buildings expressly designed for the proposed use and use of the building or buildings has not been abandoned for more than one year.

Local government projects may be permitted in resource conservation areas without obtaining growth allocation if certified by the County Council as being a project of local significance. A project of local significance is defined as a public project of minor scale which causes environmental or economic consequences that are largely confined to the immediate area of the parcel of land on which the development is located, does not substantially affect the Dorchester County Critical Area Program, and is not considered a major development by the Critical Area Commission.

Except as may be provided in Subsection C(3)(e) and (f) above, any additional structures, facilities, or uses not directly related to and a part of an existing industrial, commercial, or institutional use in terms of location, nature, and legal incorporation shall be considered new uses and must be located outside of the RCA except as may be provided by § 68-11.

Forests and developed woodlands which are cleared after the adoption of this section are to be replaced on not less than an equal basis. The formula for replacement of these forests is as follows:

If less than 20% of the forested land on the parcel is cleared, the forest shall be replaced on an equal basis.

If between 20% and 30% of the forested land on the parcel is cleared, the afforested area shall consist of 1 1/2 times the total surface acreage of the disturbed forest.

Clearing of forested land may not exceed 30% without a variance.

Where sufficient land area does not exist on the site for afforestation, an applicant may make arrangements with other landowners or the County to reforest their lands within the Critical Area.

There is hereby created a Forest Replacement Fund which shall be used to collect and disburse moneys for the sole purpose of afforestation and reforestation in the Critical Area. The fund shall be administered by the Dorchester County Planning and Zoning Office.

Any developer unable to reforest to meet the standards established above shall pay into the Forest Replacement Fund a dollar amount equal to the total cost of replacing the forest land to be cleared, including appropriate penalties.

The fee shall be calculated on a per-acre basis, and shall be determined annually by the Dorchester County Planning and Zoning Office. All fees shall be made payable to the County Treasurer.

Except as provided for otherwise, all clearing of forests and developed woodlands must take place outside of the tidewater buffer.

Man-made lot coverage must adhere to Subsection C of § 68-7 of this chapter.

If no forest or developed woodlands exist on proposed development sites, these sites shall be planted to provide a forest or developed woodland cover of at least 15%.

Development policies.

Land use management practices shall be consistent with the policies and criteria for the habitat protection area section, the agricultural section, and the forest and woodlands protection section of this chapter.[2]

Editor's Note: See § 68-24, Habitat protection; § 68-22, Agriculture; and § 68-10, Forest and woodland protection, respectively.

Agricultural and conservation easements shall be promoted in resource conservation areas.

Land within the resource conservation area may be developed for residential uses at a density not to exceed one dwelling unit per 20 acres. Within this limit of overall density, minimum lot sizes may be determined by the County. Such mechanisms as cluster development, transfer of development rights, maximum lot size provisions and/or additional means to maintain the land area necessary to support the protective uses will be encouraged by the County and implemented as necessary.

Existing industrial and commercial facilities, including those that directly support agriculture, forestry, aquaculture or residential development not exceeding the density specified above, shall be allowed in resource conservation areas.

If any existing use does not conform to the provisions of the resource conservation area, its intensification or expansion may be permitted only in accordance with the variance provisions outlined in § 68-16.

New commercial, industrial, and institutional uses shall not be permitted in resource conservation areas, except as provided for in the County's growth allocation provisions or as listed in Subsection F below. Additional land may not be zoned or used for industrial, commercial, or institutional development, except as provided by the County's growth allocation provisions.

Development activity within the resource conservation areas shall be consistent with the requirements for limited development areas as specified in this chapter.

This section applies to an application for subdivision or site plan approval within the resource conservation area that:

[Reference: Natural Resources Article 8-1808.10.]

Receives final local approval on or after July 1, 2008, unless an application for subdivision or site plan approval is submitted before July 1, 2008, and legally recorded by July 1, 2010; and

Does not involve the use of growth allocation.

Except as provided under Subsection C of this section, the minimum buffer shall be:

Two hundred feet from tidal waters or a tidal wetland; and

One hundred feet from a tributary stream.

All provisions under COMAR 27.01.09.01 that are applicable to development activities within the 100-foot buffer, including the establishment of vegetation and expansion requirements, shall apply to the 200-foot buffer.

The 200-foot buffer may be reduced if:

The strict application of the minimum 200-foot buffer would preclude:

Subdivision of the property at a density of one dwelling unit per 20 acres, and all other state and local requirements will be satisfied; or

An intrafamily transfer authorized under § 8-1808.2 of this subtitle;[3] and

Editor's Note: See the Natural Resources Article of the Annotated Code of Maryland, § 8-1808.2.

The reduction will occur in accordance with local program procedures approved by the Commission.

Calculation of 1-in-2-acre density of development. [Reference: Natural Resources Article 8-1808.1(e).]

In calculating the 1-in-20-acre density of development that is permitted on a parcel located within the resource conservation area, the County:

Shall count each dwelling unit; including dwelling units existing at the time of subdivision.

May permit the area of any private wetlands located on the property to be included under the following conditions:

The density of development on the upland portion of the parcel may not exceed one dwelling unit per eight acres; and

The area of private wetlands shall be estimated on the basis of vegetative information as designated on the state wetlands maps or by private survey approved by the County, subject to review and acceptance by the Critical Area Commission, and the State Department of the Environment.

May consider one additional dwelling unit per lot or parcel as part of a primary dwelling unit for the purpose of the density calculation under this subsection in accordance with the following provisions:

It is located within the primary dwelling unit or its entire perimeter is within 100 feet of the primary dwelling unit; does not exceed 900 square feet in total enclosed area; and is served by the same sewage disposal system as the primary dwelling unit; or

It is located within the primary dwelling unit; by its construction, does not increase the amount of lot coverage already attributed to the primary dwelling unit; and is served by the same sewage disposal system as the primary dwelling unit;

An additional dwelling unit meeting all of the provisions of this subsection may not be subdivided or conveyed separately from the primary dwelling unit; and

The provisions of this subsection may not be construed to authorize the granting of a variance, unless the variance is granted in accordance with the variance provisions in § 68-16.

Land use in the RCA. In addition to the uses specified above, certain nonresidential uses may be permitted in resource conservation areas if it is determined by the Director or designee that the proposed use is one of the following:

A home occupation as an accessory use on a residential property and as provided for in the County's Zoning Ordinance; and any lot coverage associated with the home occupation shall be limited to 20,000 square feet or 15% of the parcel, whichever is less;

A golf course developed in accordance with the official guidance adopted by the Critical Area Commission on August 3, 2005, excluding main buildings and/or structures such as the clubhouse, pro shop, parking lot, etc.; and as restricted in the Table of Permitted Uses by Zoning District in § 155-34B(1);[4]

Editor's Note: See Ch. 155, Zoning, Attachment 1.

A cemetery that is an accessory use to an existing church; provided lot coverage is limited to 15% of the site or 20,000 square feet, whichever is less;

A bed-and-breakfast facility located in an existing residential structure and where meals are prepared only for guests staying at the facility;

A gun club or skeet shooting range or similar use, excluding main buildings and/or structures, such as a clubhouse, snack bar, etc.; and as restricted in the Table of Permitted Uses by Zoning District in § 155-34B(1);[5]

Editor's Note: See Ch. 155, Zoning, Attachment 1.

A day-care facility in a dwelling where the operators live on the premises and there are no more than eight children;

A group home or assisted-living facility with no more than eight residents;

An essential service, provided the service meets a public need and is not solely for the purposes of a commercial enterprise. A privately owned wastewater treatment plant may not be located in the RCA for the purposes of serving development outside the RCA;

Other uses determined by the County and approved by the Critical Area Commission to be similar to those listed above.

Special provisions in resource conservation areas (RCA). Existing industrial, institutional and commercial facilities, including those directly supporting agriculture, forestry, aquaculture, or residential development shall be allowed in RCAs. If any existing grandfathered use does not conform to the RCA, its intensification or expansion may be permitted only in accordance with the variance procedures in § 68-16.

Conveyance of parcels participating in the agricultural easement program. Nothing in this regulation shall limit the ability of a participant in the agricultural easement program to convey real property impressed with such an easement to family members, provided that no such conveyance will result in a density greater than one dwelling unit per 20 acres.

§ 68-9 Subdivision standards in Critical Area.

It is the intent of this section to provide, as authorized by the Natural Resources Article of the Annotated Code of Maryland, § 8-1801 et seq., necessary development controls for a designated Critical Area so as to protect water quality and natural habitat associated with the Chesapeake Bay.

Greater restrictions to prevail; other applicable provisions.

The provisions of § 68-9 are in addition to other regulations of Chapter 140 Subdivision Regulations, of the Dorchester County Code. In all cases of conflicting requirements, the provision which represents the greatest restriction or highest standard shall govern.

Various other requirements also are applicable to the Critical Area and must be followed, including but not limited to the provisions set forth in the Dorchester County Zoning Ordinance, Stormwater Management Ordinance, and Erosion and Sediment Control Ordinance.[1]

Editor's Note: See Ch. 155, Zoning; Ch. 134, Stormwater Management; and Ch. 100, Grading, Erosion and Sediment Control, respectively.

General provisions.

No provision of this chapter shall preclude the subdivision of land which is developed as of the adoption date of this chapter. However, no further development shall be permitted on the parcel if:

The parcel is designated as a resource conservation area; and

The development density of the parcel as of the adoption date of this chapter exceeds that which is allowed in a resource conservation area.

Landowners within the Critical Area may exchange land between adjoining properties, provided that:

Such exchange occurs in accordance with § 140-4A(3) of the Code; and

The overall development density of the parcels subject to the exchange does not exceed that which is permitted in the designated development area.

For all proposed development activities in the Critical Area, the developer shall identify on the preliminary plat significant natural or environmental features protected under the Critical Area Law. The following site features shall be shown if they exist:

Critical Area boundaries.

Development area designations.

Tidal wetlands.

Forested lands, including developed woodlands.

Agricultural lands.

Fish and wildlife habitat areas.

Other features as required by the County Planning Director or Planning Commission.

When planning development on forested lands, the developer shall consider the recommendations of the Maryland Forest Service, Maryland Park Service and the Department of Natural Resources Wildlife and Heritage Service prior to tree cutting or clearing operations. A grading permit is required before forest or developed woodland is cleared, as detailed in the Dorchester County Erosion and Sediment Control Ordinance.[2]

Editor's Note: See Ch. 100, Grading, Erosion and Sediment Control.

New or expanded community pier and other noncommercial boat docking and storage facilities are permitted in the tidewater buffer if:

The facility:

Is water-dependent.

Meets a recognized private right or public need.

Is community owned and established and operated for the benefit of the residents of a platted and recorded riparian subdivision.

Is associated with a residential development approved by the local jurisdiction for the Critical Area and is consistent with all criteria and local regulations for the Critical Area.

Adverse effects on water quality and fish, plant and wildlife habitat are minimized.

Insofar as possible, non-water-dependent structures or operations associated with water-dependent projects or activities are located outside the buffer.

Disturbance to the buffer is the minimum necessary to provide a single point of access to the facility.

Food, fuel or other goods and services are not offered for sale and adequate and clean sanitary facilities are provided.

When a community pier with slips is provided as part of a new development project, private piers are not permitted in the development area.

The number of slips permitted at a marina facility shall be the lesser of the following:

Over 300	75 or 15%, whichever is greater

Land subdivision in the resource conservation area. If the proposed lot or lots to be subdivided within the resource conservation area contain less than 20 acres each, then the applicant must reserve sufficient land to ensure that a minimum of 20 acres, located in the resource conservation area, is reserved from further development for each lot created. Reserved lands are not included in the area of the lots created in the subdivision but are assigned a reservation status by the developer in order to ensure that there is a minimum of 20 acres in the RCA set aside from development for each lot created in the RCA. Reserved lands are restricted from further development; however, reserved lands may be utilized for agricultural, aquacultural, forestry and resource conservation purposes, including erection of buildings and structures related to these uses, provided that such uses, buildings or structures comply with all other applicable requirements of the Dorchester Zoning Ordinance and this chapter. The location and ownership of reserved land may be changed from time to time, provided that they continue to serve the purpose and meet the requirements of this section. All reserved land shall be:

Located completely within the resource conservation area.

Included with the subdivision plat in sufficient detail for the County to ascertain the actual location and area of the reserved land.

Be marked with the following notation:

"Areas within the resource conservation area shown as reserved lands on this plat may not be further subdivided, built upon or in any way developed subject to the right of the grantors to petition the Planning Commission for reduction of the land hereby reserved, in the event that further changes in the law reduce acreage necessary to be reserved."

Applicants for subdivision in the resource conservation area shall provide the County with the following information:

Total acres in the resource conservation area in the original parcel of record on or before December 1, 1985, from which the parcel proposed for subdivision was or will be subdivided, if applicable. (Note: this may require tracking the parcel back through more than one subdivision.)

Description and status of the balance of the resource conservation area portion of the original parcel since December 1, 1985. (Note: Besides the parcel for which subdivision is requested, the applicant shall determine how many other parcels in the RCA there are and if any of these parcels from the original tract has been subsequently subdivided.)

Based on this information, the County will determine:

The total permitted density for the resource conservation area portion of the parcel of record as of December 1, 1985.

Density remaining for the resource conservation area portion in light of subdivision activity involving the parcel of record as of December 1, 1985.

Assign appropriate density to the resource conservation area portion of the parcel for which subdivision (or a building permit) is being requested, if any remains.

Afforestation:

If no forest is established on the portion of a parcel being subdivided, planting shall be provided to create a forest or developed woodland cover of 15% of the portion of the parcel being subdivided.

In the case of large lot development, the Director may permit the required afforestation calculation to be based on an established building envelope for each affected lot.

Any afforestation required by this chapter shall be performed in accordance with the requirements for landscaping and planting in §§ 68-10 and 68-24 of this chapter.

§ 68-10 Forest and woodland protection.

[Reference: COMAR 27.01.05]

General policies. The following policies for forest and woodland protection recognize the value of forested land for its water quality benefits and for habitat protection while accommodating the utilization of forest resources:

Maintain and increase the forested vegetation in the Critical Area;

Conserve forests and developed woodlands and provide for expansion of forested areas;

Provide that the removal of trees associated with development activities shall be minimized and, where appropriate, shall be mitigated; and

Recognize that forests are a protective land use and should be managed in such a manner so that maximum values for wildlife, water quality, timber, recreation, and other resources can be maintained, even when they are mutually exclusive.

Identification. The County has identified and mapped forests and developed woodlands within the Critical Area and has identified and mapped habitat protection areas as described. More detailed evaluation of forest resources on specific sites shall be accomplished as part of the environmental analysis required prior to site plan and subdivision approval.

Policies for the protection of riparian and forest habitat. The County adopts the following policies for the protection of riparian habitat:

Where forests or developed woodlands occur within the County, the County shall develop a Forest Preservation Plan as part of the Critical Area Program. These plans will be developed in cooperation with the forestry programs and the Fish, Heritage and Wildlife Administration of the Department of Natural Resources and other appropriate agencies.

Each Forest Preservation Plan shall consist of the following:

Identification and mapping, or otherwise designating, forests and developed woodlands-occurring within the Critical Area;

Identification of those forest areas and developed woodlands which include habitat protection areas in COMAR 27.01.09; and which also may include forest areas that are periodically flooded within the state wetlands boundary; and

Programs to provide incentives for the conversion of other land uses to forested conditions.

Where forests or developed woodlands occur within the Critical Area, policies and programs for tree cultural operations in the Critical Area shall include all of the following:

A Forest Management Plan shall be required for all timber harvesting occurring within any one-year interval and affecting one or more acres in forests and developed woodlands in the Critical Area. The plans shall be prepared by a registered professional forester and be reviewed and approved by the forestry programs and the Fish, Heritage and Wildlife Administration of the Department of Natural Resources through the District Forestry Boards and the Project Forester, and filed with an appropriate designated agency in the County. Plans shall include measures to protect surface and ground water quality and identify whether the activities will disturb or affect habitat protection areas as identified in COMAR 27.01.09, and incorporate protection measures for these areas as specified by the County. To provide for the continuity of habitat, the plans shall address mitigation through forest management techniques which include scheduling size, timing and intensity of harvest cuts, afforestation, and reforestation.

A sediment control plan shall be required for all harvests of 5,000 square feet or more of disturbed area in the Critical Area, including harvesting on agricultural lands, this plan shall be developed according to the state guidelines entitled: "Standard Erosion and Sediment Control Plan for Forest Harvest Operations." The operations shall be implemented in accordance with specifications set out by the forestry programs and the Fish, Heritage and Wildlife Administration of the Department of Natural Resources, and enforced by the Department of Natural Resources.

The cutting or clearing of trees within the 100-foot buffer, as described in COMAR 27.01.09, shall be in accordance with that chapter.

§ 68-11 Reforestation and afforestation standards beyond buffer.

[Reference: Existing County procedures.]

Afforestation.

If no forest is established on the portion of a parcel being subdivided, planting shall be provided to create a forest or developed woodland cover of at least 15% of the portion of the parcel being subdivided.

In the case of grandfathered large-lot development, the Director may permit the required afforestation calculation to be based on an established building envelope not less than one acre for each affected lot.

All forests designated on development plans shall be maintained to the extent practicable, through conservation easements, restrictive covenants, or other protective instruments;

The developer shall designate, subject to the approval of the local jurisdiction, a new forest area on a part of the site not forested; and

The afforested area shall be maintained as forest cover through easements, restrictive covenants, or other protective instruments.

Editor's Note: See Ch. 155, Zoning.

Subdivision afforestation review fees. Fees to cover the costs of considering, examining and checking the several plats and plans required herein and of recording the final plat shall be collected at the time of filing a preliminary plat, in accordance with a fee schedule of charges, adopted by resolution of the Dorchester County Council.

Site plan planting plan requirements. Landscaping and planting.

Applicability. This section does not apply to the planting of vegetated buffers, forests or landscaping done pursuant to the Dorchester County Forest Conservation Program.

Required landscaping. When landscaping or the planting of a vegetated buffer is required as a condition of this chapter, or as a condition of approval by the Board of Appeals or Planning Commission, the planting or landscaping must either be:

Completed prior to final approval of the project; or

Subject to a planting agreement.

Planting agreements.

Planting agreements shall:

Be prepared on forms approved by the County Attorney;

Include some form of financial surety in an amount equal to at least 120% of the estimated cost of completing the project; and

Provide for the continued maintenance of the planted area once completed.

Site plan schedule of fees and charges. The County Council shall establish a schedule of fees, charges and expenses and a collection procedure for applications for special exceptions, variances, amendments, appeals, permits and other matters pertaining to this chapter. Such schedule shall be posted in the office of the Director of Planning and may be altered or amended, from time to time, without a public hearing, only by the County Council upon the recommendations of the Planning Commission. Until all applicable fees, charges and expenses have been paid in full, no action shall be taken on any application or appeal pertaining to this chapter.

§ 68-12 Growth allocation.

[Reference: Natural Resources Article 8-1808.1 and COMAR 27.01.02.06.]

Description. Growth allocation means the number of acres of land in the Critical Area that a local jurisdiction may use to create new intensely developed areas and new limited development areas. The growth allocation acreage available to the County was calculated based on 5% of the total resource conservation area in the County at the time of the original approval of the County's program by the Critical Area Commission, not including tidal wetlands or land owned by the federal government.

Growth allocation acreage. At the time of Critical Area Program adoption there were 58,000 acres classified as RCA. The County's original growth allocation acreage was 2,900 acres. To date, 1,416 acres have been awarded or used; remaining growth allocation for use by the County is 1,486 acres.

Standards. When locating new intensely developed or limited development areas, the following standards shall apply:

Locate a new intensely developed area in a limited development area or adjacent to an existing intensely developed area;

Locate a new limited development area adjacent to an existing limited development area or an intensely developed area;

New intensely developed areas shall be at least 20 acres in size unless:

They are contiguous to an existing IDA or located in an LDA; or

They are a grandfathered commercial or industrial use which existed as of August 23, 1988. The amount of growth allocation deducted shall be equivalent to the area of the entire parcel or parcels subject to the growth allocation request.

No more than 1/2 of the County's growth allocation may be located in resource conservation areas except as provided in Subsection C(9) below;

Locate a new limited development area or intensely developed area in a manner that minimizes impacts to habitat protection area as defined in COMAR 27.01.09 and in an area and manner that optimizes benefits to water quality;

Locate new intensely developed areas where they minimize their impacts to the defined land uses of the resource conservation area;

Locate a new intensely developed area or a limited development area in a resource conservation area at least 300 feet beyond the landward edge of tidal wetlands or tidal waters;

New intensely developed or limited development areas to be located in resource conservation areas shall conform to all criteria of the County for such areas, shall be so designated on the County Critical Area Maps and shall constitute an amendment to this program subject to review and approval by the County Planning Commission, the County Council and the Critical Area Commission.

If the County is unable to utilize a portion of its growth allocation as set out in Subsection C(1) and (2) above within or adjacent to existing intensely developed or limited development areas, then that portion of the allocated expansion which cannot be so located may be located in the resource conservation areas in addition to the expansion allowed in Subsection C(4) above. An applicant shall be required to cluster any development in an area of expansion authorized under this paragraph.

A growth allocation application for a residential subdivision shall comply with the requirements of Environment Article § 9-206 of the Annotated Code of Maryland, and Land Use Article, Title 1, Subtitle 5, and § 5-104 of the Annotated Code of Maryland.

Additional factors. In reviewing map amendments or refinements involving the use of growth allocation, the Critical Area Commission shall consider the following factors:

Consistency with the County's adopted Comprehensive Plan and whether the growth allocation would implement the goals and objectives of the adopted plan. "Consistency with" means that a standard or factor will further, and not be contrary to, the following items in the Comprehensive Plan:

Policies;

Timing of the implementation of the plan, of development, and of rezoning;

Development patterns;

Land uses; and

Densities or intensities.

For a map amendment or refinement involving a new limited development area, whether the development is:

To be served by a public wastewater system or septic system that uses the best available nitrogen removal technology;

A completion of an existing subdivision;

An expansion of an existing business; or

To be clustered;

For a map amendment or refinement involving a new intensely developed area, whether the development is:

To be served by a public wastewater system;

A completion of an existing subdivision;

An expansion of an existing business; or

To be clustered;

The use of existing public infrastructure, where practical;

Consistency with state and regional environmental protection policies concerning the protection of threatened and endangered species and species in need of conservation that may be located on or off site;

Impacts on a priority preservation area, as defined under Agriculture Article, § 2-518, Annotated Code of Maryland;

Environmental impacts associated with wastewater and stormwater management practices and wastewater and stormwater discharges to tidal waters, tidal wetlands, and tributary streams; and

Environmental impacts associated with location in a coastal hazard area or an increased risk of severe flooding attributable to the proposed development.

Application of standards and additional factors. When the County submits a request for the Critical Area Commission to review and approve the use of growth allocation, the request shall state how the County has applied the preceding standards and shall provide information as necessary for the Critical Area Commission to consider the additional factors set forth above. The Critical Area Commission shall ensure that standards set forth in this section have been applied in a manner that is consistent with the purposes, policies, goals, and provisions of the Critical Area Law and all criteria of the Critical Area Commission.

Deduction methodology.

Definitions. As used in this Subsection F, the following terms shall have the meanings indicated:

DEDUCTION: The total number of growth allocation acres that are necessary for approval of a growth allocation project and, after approval by the Critical Area Commission, are subtracted from the growth allocation reserves of Dorchester County.

GROWTH ALLOCATION ENVELOPE: All of the proposed components of a growth allocation project that are necessary to serve the proposed development, including an individually owned lot, lot coverage, a road, a utility, a stormwater management measure, an on-site sewage disposal measure, an active recreation area, and additional acreage needed to meet the development requirements of the Critical Area criteria.

The following standards shall be used to determine the area of growth allocation to be deducted when the designation of a parcel or a portion of a parcel is changed through the growth allocation process:

Subdivision of any parcel of land that was recorded as of December 1, 1985, and classified as RCA where all or part of the parcel is identified by the County as a growth allocation area, shall result in the acreage of the entire parcel, not in tidal wetlands, being deducted from Dorchester County's growth allocation, unless the development envelope concept outline in Subsection F(2)(b), below, is used.

In order to allow some flexibility in the use of growth allocation when development is only proposed on a portion of the property, the following methodology may be used. On a parcel proposed for the use of growth allocation, a single growth allocation envelope may be specified, and the acreage of the growth allocation envelope rather than the acreage of the entire parcel shall be deducted from the County's growth allocation if the growth allocation envelope meets the following criteria:

Only one growth allocation envelope shall be established per parcel of land unless:

Deduction of more than one growth allocation envelope will provide a water quality or habitat benefit; and

The Critical Area Commission approves the use of more than one growth allocation envelope.

A minimum of 20 acres must remain outside of the growth allocation envelope or the acreage of the entire parcel must be deducted. The minimum twenty-acre residue outside of the growth allocation envelope may be developed at an RCA density unless some type of permanent protection exists that restricts development.

If the original parcel in the RCA is less than 20 acres, the acreage of the entire parcel must be deducted unless there is an adjacent, contiguous, permanently protected RCA on another parcel, resulting in a minimum twenty-acre total. Provided that the permanent protections are in place on the minimum 20 acres, the growth allocation envelope may be used.

The following may be excluded from a growth allocation deduction:

The acreage of a 300-foot setback, even when it is less than 20 acres;

The acreage within a buffer when it is within a 300-foot setback; and

The acreage of tidal wetlands on the parcel.

Process. Applicants for growth allocation shall submit a request for growth allocation accompanied by appropriate plans and environmental reports in accordance with the following process:

All applications for growth allocation shall be submitted to DP&Z. Requests shall be accompanied by a concept plan and appropriate environmental reports and studies so as to provide sufficient information to permit the Planning Commission to review the application for consistency with the County's Critical Area regulations. The subdivision history of parcels designated as RCA must be provided as part of the growth allocation application. The date of December 1, 1985, is the date used for the original Critical Area mapping and shall be used as a beginning point of analysis.

All applications for growth allocation shall be forwarded to the Planning Commission for review and shall include comments and recommendations from the staff. The Planning Commission shall hold a public hearing on the growth allocation request prior to making a recommendation on the proposal to the County Council.

The applicant shall address the Planning Commission's comments and recommendations and may revise the concept plan accordingly. The growth allocation request shall then be forwarded to the County Council with a recommendation for approval or denial from the Planning Commission.

The County Council shall hold a public hearing on the request for growth allocation and any revisions to the concept plan.

The County Council may establish conditions of approval that are consistent with the intent of the County's Critical Area Program.

Upon approval of the growth allocation request by the County Council, the County shall send a request to the Critical Area Commission to utilize a portion of their growth allocation. The request shall be accompanied by pertinent plans and environmental reports and studies. Upon receipt of the request from the County, the Critical Area Commission shall notify the County regarding the processing of the request as an amendment or refinement to the County's Program. Refinements shall be acted on within 130 days of the Critical Area Commission's notification to the County of a complete submission. Amendments will be acted on within 130 days of the Critical Area Commission's notification of a complete submission.

Following approval of the growth allocation request by the Critical Area Commission, the County Council shall incorporate it into the Critical Area Ordinance within 120 days of Commission approval, and the applicant may proceed to the preparation of the final site plan or subdivision plat for recording in the County land records.

Prior to approving the final site plan or subdivision plat, the Planning Commission or its designee shall ensure that all conditions of approval, including those from the Critical Area Commission, are incorporated into the final plan, public works agreement, deed covenants, etc.

Final subdivision plats and site plans shall be processed in accordance with the requirements of this chapter and the County's subdivision regulations.[1]

Editor's Note: See Ch. 140, Subdivision Regulations.

The County's official Critical Area maps shall be amended to reflect the new land classification, and a copy of the new map shall be provided to the Critical Area Commission. Dorchester County shall require deduction of the number of growth allocation acres that are shown on the locally approved map.

As a condition of approval, the County may require that all projects approved for the use of growth allocation shall demonstrate that they are substantially completed within three years of the date of growth allocation approval by the Critical Area Commission. Substantially completed shall be determined by the Planning Commission and is defined as projects in which all public improvements, such as roads, sewer and/or water facilities, etc., have been built as required by the County.

Standards. The Planning Commission or its designee shall review a proposed lot consolidation or reconfiguration and will make written findings that each one of the following standards has been met:

The proposed consolidation or reconfiguration will result in no greater number of lots, parcels, or dwelling units in the Critical Area than the existing configuration would allow;

The proposed lot consolidation or reconfiguration will result in no greater lot coverage than the existing configuration would allow;

The proposed consolidation or reconfiguration does not:

Create an additional riparian lot or parcel, waterfront lot, or any other lot or parcel deeded with water access; or

Intensify or increase impacts associated with riparian access;

The proposed consolidation or reconfiguration does not create:

A lot or parcel or portion of a lot or parcel that will serve development activities outside the Critical Area; or

A resource conservation area lot or parcel that serves development activities in the intensely developed area or limited development area;

The proposed consolidation or reconfiguration identifies each habitat protection area and, if impacts to a habitat protection area are proposed, the proposal demonstrates that:

No greater impact to a habitat protection area would result than the impact that would have resulted from the existing lot configuration;

Adverse impacts to a habitat protection area are minimized; and

Protective measures and restoration measures are included that provide for the least possible impact;

The proposed consolidation or reconfiguration provides:

Stormwater management for all proposed development activities; and

Benefits to fish, wildlife, and plant habitat that are clearly identified.

Approval and notification. Based upon the standards, the Planning Commission or its designee shall issue a final written decision or order granting or denying an application. A copy of a final decision or order shall be submitted to the Critical Area Commission, and, if applicable, the approved development plan, within 10 days of the final approval, by United States mail to the Critical Area Commission's business address. The County may not issue a building permit until the appeal time has expired.

§ 68-15 Intrafamily transfers.

[Reference: Natural Resources Article 8-1808.2.]

Applicability. "Bona fide intrafamily transfer" means a transfer, to a member of the owner's immediate family, of a portion of the owner's property for the purpose of establishing a residence for that family member.

An owner of a parcel of land in a resource conservation area (RCA) may transfer a portion of his/her property to an immediate family member, notwithstanding the density provisions of the Critical Area Protection Program and § 68-8C(1). Any lot or parcel in the RCA subject to an intrafamily transfer subdivision must be seven acres or more but less than 60 acres in size and must be a lot or parcel of record as of March 1, 1986.

A lot or parcel in the RCA that is seven acres or more but less than 12 acres in size may be subdivided into two lots. A lot or parcel in the RCA that is 12 acres or more but less than 60 acres in size may be subdivided into three lots. The lots may be created at different times.

A lot or parcel that is subdivided by means of a bona fide intrafamily transfer:

May be transferred only to a member of the owner's immediate family for the purpose of establishing a residence for that family member. Only the recipient of a lot through an intrafamily transfer may request a building permit for a structure on a lot created through this process. For the purposes of this section, "immediate family" means a father, mother, son, daughter, grandfather, grandmother, grandson, granddaughter, or sibling who has attained the age of 21 years as of the date of the recording of the subdivision plat;

Must comply with Chapter 140, Subdivision Regulations, and Chapter 155, Zoning, of the Dorchester County Code and COMAR 27.01.01.01, et seq.;

May not be further subdivided; and

May not be conveyed subsequently to any person other than a member of the owner's immediate family, except for a conveyance to a third party as security for a mortgage or deed of trust and except for a conveyance resulting from court proceedings, including bankruptcy, divorce, mental competency, probate, foreclosure, etc., or from the disposition of a will or trust. An exception from this limitation may be obtained from the Board of Appeals if the applicant proves that:

The lot was created as part of a bona fide intrafamily transfer and not with the intent of subdividing the original parcel of land for the purpose of ultimate commercial sale; and

A change in circumstances has occurred since the original transfer was made that is not inconsistent with this section and warrants an exception. Changes in circumstances include situations where the intrafamily transfer recipient has not resided in the County for five years prior to application for an exception or suffers significant financial hardship. The Board may define such hardship as being unable to meet all financial obligations for the preceding six months.

Any deed for a lot created by bona fide intrafamily transfer shall contain a covenant stating that the lot is created subject to the provisions of this section.

Any plat or site plan for a lot created by a bona fide intrafamily transfer shall contain notes stating that the lot is created subject to the provisions of this section.

Special circumstances.

On lots created by an intrafamily transfer subdivision for which application was made prior to January 1, 2010, and for which final approval was granted after March 8, 2010, development in and disturbances to the expanded tidewater buffer for hydric or highly erodible soils may be permitted without a variance, provided that all other subdivision requirements are met or, in the case of County road standards, waived. Mitigation at a ratio of 3:1 must be provided for any development activities in and disturbances to the expanded buffer for hydric or highly erodible soils. Nothing in the above is meant to allow development in or disturbances to 100- or 200-foot tidewater buffers.

Pursuant to COMAR 27.01.09.01.e.6.c, in the case of an application for an intrafamily transfer subdivision approved after July 1, 2010, the 200-foot buffer required by COMAR 27.01.09.01.e.5 may be reduced to the minimum width necessary to allow approval of the intrafamily transfer subdivision, but no less than the 100-foot tidewater buffer, provided that the strict application of the 200-foot buffer would preclude the intrafamily transfer subdivision.

Further subdivisions or transfers of ownership.

A lot or parcel that is subdivided by means of a bona fide intrafamily transfer:

Must comply with Chapter 140, Subdivision Regulations, and Chapter 155, Zoning, of the Dorchester County Code and COMAR 27.01.01.01 et seq.;

May not be further subdivided; and

The lot was created as part of a bona fide intrafamily transfer and not with the intent of subdividing the original parcel of land for the purpose of ultimate commercial sale; and

Any deed for a lot created by bona fide intrafamily transfer shall contain a covenant stating that the lot is created subject to the provisions of this section.

Any plat or site plan for a lot created by a bona fide intrafamily transfer shall contain notes stating that the lot is created subject to the provisions of this section.

§ 68-16 Variances.

[Reference: Natural Resources Article 8-1808(c)(1)(ii), 8-1808(d) and COMAR 27.01.12.]

Applicability. The County has established provisions where, owing to special features of a site or other circumstances, implementation of this program or a literal enforcement of provisions within the program would result in unwarranted hardship to an applicant, a Critical Area Program variance may be obtained. In this chapter, "unwarranted hardship" means that, without a variance, an applicant shall be denied reasonable and significant use of the entire parcel or lot for which the variance is requested. In considering an application for a variance, the County shall presume that the specific development activity in the Critical Area, that is subject to the application and for which a variance is required, does not conform with the general purpose and intent of Natural Resources Article, Title 8, Subtitle 18, COMAR Title 27, and the requirements of the County's Critical Area Program.

Standards. A variance shall only be granted if the applicant proves to the satisfaction of the Director of DP&Z or, when applicable, to the County Board of Appeals, based upon written application and testimony, that all of the following standards are met:

Due to special features of the site or special conditions or circumstances peculiar to the applicant's land or structure, a literal enforcement of the Dorchester County Critical Area Program would result in an unwarranted hardship to the applicant;

A literal interpretation of the Dorchester County Critical Area Program would deprive the applicant of a use of land or a structure permitted to others in accordance with the provisions of this chapter;

The granting of the variance would not confer upon the applicant any special privilege that would be denied by this chapter to other lands or structures in accordance with the provisions of the Dorchester County Critical Area Program;

The variance request is not based upon conditions or circumstances that are the result of actions by the applicant;

The variance request does not arise from any conforming or nonconforming condition on any neighboring property;

The granting of the variance would not adversely affect water quality or adversely impact fish, wildlife, or plant habitat within the Dorchester County Critical Area;

The granting of the variance would be in harmony with the general spirit and intent of the Critical Area Law, the provisions of this chapter, and the Dorchester County Critical Area Program.

That the applicant has the burden of proof and the burden of persuasion to overcome the presumption of nonconformance pursuant to Subsection B(5).

That based on competent and substantial evidence, the approving authority shall make written findings as to whether the applicant has overcome the presumption of nonconformance as established above.

That the written findings may be based on evidence introduced and testimony presented by the applicant, the County or any other government agency, or any other person deemed appropriate by the County.

Application. Applications for a variance will be made in writing with a copy provided to the Critical Area Commission. The applicant has the burden of proof and the burden of persuasion to overcome the presumption of nonconformance established in Subsection A above. The County shall notify the Critical Area Commission of its findings and decision to grant or deny the variance request.

Standard variance process.

Applications for a variance or administrative variance shall be made in writing to the Dorchester County Board of Zoning Appeals or Planning Director, respectively, in accordance with the procedures set forth herein. The Critical Area Commission shall receive a copy of the application for any variance or administrative variance that relates to the Critical Area at least 15 days prior to any hearing on such matter and shall receive a copy of the finding. Variance or administrative variance decisions may be appealed as provided herein. In addition, the Chairman of the Critical Area Commission may appeal an action or decision, even if the Chairman was not a party to or is not specifically aggrieved by the action or decision.

Appeals for variances from the strict application of this chapter shall be made to the Board of Appeals on forms provided by the Director of Planning and Zoning. Such applications shall be acted upon within a reasonable time, not to exceed 60 days from the date of the receipt of the application or such lesser period as may be provided by the rules of the Board. Applications for variance shall be accompanied by the required fees, as established by the County Council, and shall be filed with the Director of Planning and Zoning, who shall forthwith transmit to the Board all papers constituting the record upon which the action appealed from was taken.

No permit, approval, variance or special exception for any property located within the CA-Critical Area Protection District shall be issued, unless the person seeking the permit, approval, variance, or special exception has:

Fully paid all administrative, civil, and criminal penalties imposed by Chapter 155, Zoning, of the Dorchester County Code for violation for the subject property within the CA-Critical Area Protection District; and

Prepared a restoration or mitigation plan, approved by the County, to abate impacts to water quality or natural resources as a result of the violation for the subject property within the CA-Critical Area Protection District; and

Performed the abatement measures in the approved plan in accordance with the County's Critical Area Program for the subject property; and

Satisfaction of all conditions specified under this section shall be a condition precedent to the issuance of any permit, approval, variance, or special exception for the affected property; and

Unless an extension of time is appropriate because of adverse planting conditions, within 90 days of the issuance of a permit, approval, variance, or special exception for the affected property, any additional mitigation required as a condition of approval for the permit, approval, variance, or special exception shall be completed.

Hearings; notification.

The Board shall fix a reasonable time for the hearing of appeals and applications, consistent with its rules of practice and procedure. Public notice shall be given by the Board of all hearings relating to zoning matters in accordance with the procedures set forth in § 155-6, Requirements for public notices, of the Code.

Calendar of the Board.

A calendar of the Board showing the times and dates of hearings relating to zoning matters shall be maintained and posted in a conspicuous location in the office of the Director of Planning. The Board shall assure that a current copy of the calendar is provided to the Planning Commission.

Advice from Planning Commission.

Before deciding any application for special exception or variance, the Board of Appeals shall seek the advice and recommendation of the Planning Commission in reference to such applications. The advice of the Planning Commission shall not be binding upon the Board of Appeals. The Board may request from the Planning Commission such technical service, data or factual evidence as will further assist the Board in reaching decisions, and any such information forwarded by the Planning Commission shall be incorporated into the record, and it shall also be made available to the applicant, should he so desire.

Stay of proceedings.

An appeal that is filed with the Board of Appeals stays all actions by the Director of the Department of Planning and Zoning seeking enforcement of or compliance with the order or decision appealed from, unless the Director certifies to the Board of Appeals that (because of facts stated in the certificate), in his opinion, such stay will cause imminent peril to life or property. In that case, proceedings shall not be stayed except by order of the Board of Appeals or a court-issued application of the party seeking the stay, for due cause shown, after notice to the Director.

Withdrawal; subsequent appeals or reapplication.

If an application or appeal is disapproved by the Board of Appeals, thereafter the Board shall not accept for filing another application for substantially the same proposal on the same premises until after one year from the date of such disapproval.

An appeal or application may be withdrawn prior to advertisement of the hearing without prejudice; however, the fees for such appeal or application may be retained by the County, at the discretion of the Board of Appeals.

In the event that an appeal or application is withdrawn subsequent to advertisement of the public hearing, the applicant shall be precluded from filing another application or appeal for substantially the same proposal on the same premises for one year from the date of withdrawal unless good cause shall be shown to the Board. The fees for such application or appeal may be retained by the County, at the discretion of the Board of Appeals.

Appeals to court.

Time limit for appeal. Any person allegedly aggrieved by any decision of the Board of Appeals or by a reclassification by the County Council may appeal the same to the Circuit Court of Dorchester County within 30 days of the notification of the decision.

Stays. The filing of an appeal does not stay an order or action of the Board of Appeals. Upon motion and after hearing, the Court may grant a stay, unless prohibited by law, upon conditions as to bond or otherwise that the Court considers proper.

Cost of transcript. The appellant shall be responsible for paying the expense of transcription.

Hearing; testimony. If, upon the hearing, it shall appear to the Court that testimony is necessary for the proper disposition of the matter, it may take evidence or appoint a referee to take such evidence as it may direct and report the same to the Court, with his proposed findings of fact and conclusions of law, which shall constitute a part of the proceedings upon which the determination of the Court shall be made.

Liability of Board of Appeals for costs. Costs shall not be allowed against the Board of Appeals unless it shall appear to the Circuit Court that the Board acted with gross negligence or in bad faith or with malice in making the decision appealed from.

Decision; subsequent appeals. Upon its determination of the case, the Circuit Court shall file a formal order embodying its final decision. An appeal may be taken to the Court of Special Appeals of Maryland or the Court of Appeals of Maryland, during the period and in the manner prescribed by the rules of the Court of Appeals, from any decision of the Circuit Court. In such cases, the award of costs shall be subject to the discretion of the Court of Appeals.

Administrative variance process. The Planning Director may use the administrative variance process as follows:

On a lot or parcel that was recorded before January 1, 2010, an administrative variance in the Critical Area may be granted for the replacement, expansion, or relocation of a legally existing, nonconforming structure, the construction of a new accessory structure, the construction of a new primary structure, or the construction or relocation of a driveway, sidewalk, patio or other similar lot coverage within the buffer that meets the following conditions:

In the case of the replacement of a structure or the expansion of a structure in the 100-foot tidewater buffer:

The replacement or expansion does not encroach any further than the existing structure into the 100-foot tidewater buffer, unless the proposed development is restricted by more than one buffer; in this case, the proposed expansion may not encroach any further than 50 feet into any one of the buffers;

The proposed expansion will not enlarge the existing footprint of the structure by greater than 30% of the primary structure that existed on March 8, 2010, or 500 square feet, whichever is greater;

The property will comply with the lot coverage restrictions in § 68-7C(10) and (11). A lot coverage exchange may be conducted in accordance with § 68-7C(10)(g).

Except as in COMAR 27.01.09.01.e.8, in the case of a replacement of a structure or the expansion of a structure in the expanded buffer:

The replacement or expansion does not encroach into the 100-foot tidewater buffer;

The proposed expansion will not enlarge the existing footprint of the structure by greater than 30% of what existed on March 8, 2010, or 500 square feet, whichever is greater; and

The property will comply with the lot coverage restrictions in § 68-7C(10) and (11). A lot coverage exchange may be conducted in accordance with § 68-7C(10)(g).

In the case of a relocated structure within the 100-foot or expanded buffer:

The relocated structure lessens the extent of the nonconformity, unless the proposed development is restricted by more than one buffer; in this case the proposed relocation may not encroach any further than 50 feet into any one of the buffers.

In the case of the construction of a driveway in the 100-foot and/or expanded buffer:

The routing of the driveway through the buffer shall provide direct access to the property, given site conditions, and for which there is no feasible alternative. Tree clearing and impacts to habitat protection areas as defined in § 68-24 shall be minimized;

The width of the driveway shall not exceed 12 feet;

The property will comply with the lot coverage restrictions in § 68-7C(10) and (11). A lot coverage exchange may be conducted in accordance with § 68-7C(10)(g).

In the case of a new accessory structure or other lot coverage in the 100-foot or expanded buffer, excluding pools, as indicated in Subsection E(2) below:

The new accessory structure or other lot coverage will not be located any further shoreward than the closest point of the existing primary structure, unless the proposed development is restricted by more than one buffer; in this case the proposed expansion may not encroach any further than 50 feet into any one of the buffers;

The footprint of the new accessory structure or other lot coverage will not exceed 30% of the footprint of the primary structure as it existed on March 8, 2010;

If no lot coverage associated with a primary structure existed on the site as of March 8, 2010, the footprint of the new accessory structure or other lot coverage will not exceed 500 square feet;

The property will comply with the lot coverage restrictions in § 68-7C(10) and (11) and accessory structure limitations in § 155-50A. A lot coverage exchange may be conducted in accordance with § 68-7C(10)(g); and

The footprint of any new accessory structure or other lot coverage approved by an administrative variance shall be counted against the expansion of a primary structure allowed under § 68-16E.

Except as in COMAR 27.01.09.01.e.8, in the case of a new primary structure in the expanded buffer:

The new primary structure and any associated parking pad, accessory structure or other lot coverage, excluding driveways as applicable to Subsection E(1)(d) above, shall not encroach into the 100-foot tidewater buffer;

The footprint of the new principal structure, any associated parking pad, accessory structure and/or other lot coverage within the expanded buffer shall not exceed 2,500 square feet;

The width of a proposed driveway within the expanded buffer shall not exceed 12 feet; and

The property will comply with the lot coverage restrictions in § 68-7C(10) and (11). A lot coverage exchange may be conducted in accordance with § 68-7C(10)(g).

In the case of a deck attached to the primary structure, the following requirements must be met:

Within the 100-foot buffer:

The deck is constructed with decking material that has gaps to allow water to pass freely;

Lot coverage cannot be located over and/or under the proposed deck;

The deck will be no greater than 500 square feet; and

The location of the deck cannot result in the 100-foot buffer being reduced to less than 50 feet.

Within the expanded buffer:

The deck is constructed with decking material that has gaps to allow water to pass freely;

Lot coverage cannot be located over and/or under the proposed deck;

The deck will be no greater than 500 square feet; and

The location of the deck does not encroach into the 100-foot buffer.

An approval of a deck(s) through an administrative variance:

Does not expand the footprint of the existing structure;

Does not allow the deck to become the closest point to the water of the structure to which it is attached; the closest point shall remain within the footprint of the existing structure.

A deck(s) approved by an administrative variance shall not be converted to lot coverage.

The administrative variance process is not applicable to a pool in the 100-foot or expanded buffer. An applicant seeking a variance for a pool in the 100-foot or expanded buffer must follow the standard variance process, per § 68-16D.

The Planning Director shall:

Approve, approve with conditions, or deny an administrative variance in the Critical Area pursuant to the standards for variances as expressed in § 68-16 and Natural Resources Article 8-1808(d);

Make written findings, based on competent and substantial evidence, as to whether the applicant has overcome the presumption of nonconformance established in § 68-16B(8), including that the granting of the variance will not adversely affect water quality or adversely impact fish, wildlife, or plant habitat within the Critical Area, and that the granting of the variance will be in harmony with the general spirit and intent of the Critical Area Law and criteria; and

Base his/her written findings on evidence introduced and testimony presented by the applicant, the County, or any other government agency, or any other person deemed appropriate by the County, with due regard for the person's experience, technical competence, and specialized knowledge.

A recommendation from the Planning Commission is required for all administrative variances.

The following disturbances are exempt from needing an administrative variance from the 100-foot and expanded buffer.

An in-kind replacement of a legally existing, nonconforming structure.

The construction of steps and landings, built to the current minimum Building Code requirement, for access to a structure.

In the case of an approval of an administrative variance under this subsection, the Planning Director shall require the following:

For § 68-16E(1)(a) through (e), mitigation is required for all new disturbance in the 100-foot or expanded buffer in accordance with COMAR 27.01.09.01-2;

For § 68-16E (1)(f), the Planning Director shall require full establishment of the 100-foot tidewater buffer, or mitigation for all disturbance to the expanded buffer at 3:1, whichever is greater, in accordance with the planting standards found in COMAR 27.01.09.01-2;

Mitigation plantings shall be located in the following order of priority:

Within the 100-foot buffer;

Within the expanded buffer;

On site and adjacent to the buffer; and

On site and elsewhere in the Critical Area;

If buffer mitigation cannot be planted in accordance with § 68-25E, a fee-in-lieu shall be collected in accordance with § 68-25J.

The Planning Director shall require a buffer management plan approved by the Dorchester County Planning and Zoning Office in accordance with COMAR 27.01.09.01-3.

Decisions on administrative variances by the Planning Director may be appealed within 30 days to the Board of Appeals.

Adjoining property owners will be notified by mail of an application for an administrative variance as part of the Planning Commission recommendation process.

Administrative variances granted for the expansion of existing structures are intended to be construed as cumulative for each structure subject to said variance.

Conditions and mitigation. In granting a variance, the approving authority may impose reasonable conditions to assure that the spirit and intent of the Critical Area Program is maintained.

Having determined that the necessary standards for a Critical Area variance have been met, the applicant will take steps to mitigate impacts, including:

Reforestation on the site to offset disturbed forest or developed woodlands on at least an equal area basis.

Afforestation to mitigate any lot coverage created and to mitigate for all disturbance to the buffer, measured as a calculation of square feet disturbed, on at least a three to one ratio per COMAR 27.01.09.01-2; and

Implementation of any mitigation measures that relate to habitat protection areas as delineated in the County Critical Area Ordinance, or as recommended by state and/or County agencies.

The approving authority shall prescribe time limits within which any conditions to a variance must be completed. Failure to complete any of the prescribed conditions within the time limits set shall be a violation of this chapter and, at the discretion of the Director of DP&Z, after notice and hearing, shall be grounds for termination or revocation of the variance. Under no circumstance, unless otherwise specified by the Director of DP&Z, or extended by order of DP&Z, shall the time limits exceed two years from the date of the variance decision.

Standing. In accordance with Natural Resources Article, § 8-1808(d)(2), Annotated Code of Maryland, if a person meets the threshold standing requirements under federal law, the person shall have standing to participate as a party in a local administrative proceeding.

Commission notification. Within 10 working days after a written decision regarding a variance application is issued, the Critical Area Commission must receive a copy of the written decision. The County may not issue a permit for the activity that was the subject of the application until the applicable thirty-day appeal period has elapsed.

Appeal to the Board of Zoning Appeals.

In considering an application for a variance, the Board of Zoning Appeals shall presume that the specific development activity in the Critical Area, that is subject to the application and for which a variance is required, does not conform with the general purpose and intent of Natural Resources Article Title 8, Subtitle 18, COMAR Title 27, and the requirements of the County's Critical Area Program.

The Board of Zoning Appeals shall follow the standards and procedures outlined in § 68-16A through D and F through H.

Appeals to Circuit Court. Variance decisions by the Board of Zoning Appeals may be appealed to the Circuit Court in accordance with the Maryland Rules of Procedure. Appeals may be taken by any person, firm, corporation or governmental agency aggrieved or adversely affected by any decision made under this section.

§ 68-17 State and local development projects.

[Reference: COMAR 27.02.02, COMAR 27.02.04 and COMAR 27.02.06.]

Applicability. For all development in the Critical Area resulting from state and local agency projects, the County shall adhere to COMAR 27.02.02, COMAR 27.02.04 and COMAR 27.02.06. If applicable, consistency reports shall be submitted to the Critical Area Commission.

Procedures. The sponsoring agency of any development project within the County's Critical Area shall work with the DP&Z to identify the appropriate procedures for determining compliance with the state and local Critical Area Program requirements. A determination will be made regarding whether the project is one of local significance or if it meets the definition of "major development," which requires approval by the Critical Area Commission.

Standards for projects of local significance. For any development activity within the Critical Area, the County agency proposing the project shall work with the DP&Z to ensure that the project is consistent with all of the provisions and requirements of the County's Critical Area Program.

At least 14 days were provided for public comment; and

The property proposed for development was posted in accordance with the provisions for posting in Subsection F, below.

In addition to the public notice required in Subsection E(1), the County may provide for public notice by electronic posting on its website, on the website of a newspaper of general circulation in the geographic area where the proposed development would occur, or by notification to a neighborhood association or residents of a particular geographic area.

Evidence of public notice to be submitted to the Critical Area Commission shall include the following documentation:

The name of the newspaper and the date on which the notice was published;

A copy of the public notice as it was published in the newspaper; and

A copy of each written comment received in response to the public notice.

Posting requirements for major development. [Reference: COMAR 27.03.01.03.]

The sponsoring agency for any major development project shall ensure that a sign is posted on the property indicating that the site is proposed for major development. Posting shall meet the following requirements:

Shall consist of at least one sign that is a minimum of 30 inches by 40 inches in size;

The sign clearly:

Identifies the sponsoring agency;

Describes the proposed development;

Provides the street address of the affected land and states that it is located in the Critical Area; and

States the name and contact information of the person within the sponsoring agency designated to receive public comment, including a fax number and e-mail address, and the deadline for receipt of public comment;

On a date not later than the date on which the notice is published in the newspaper, the sign shall be posted in a conspicuous location on the development site and shall remain there until after the Critical Area Commission has voted on the development; and

For development that extends more than 1,000 linear feet in road frontage, at least one sign shall be posted at each end of the affected land on which the development is proposed.

§ 68-18 Program changes.

[Reference: Natural Resources Article 8-1809(g) through (s).]

Program changes. The County Council may from time to time amend the County Critical Area Program. Critical Area Program changes include, but are not limited to, amendments, revisions, and modifications to zoning regulations, subdivision regulations, Critical Area maps, implementation procedures, and local policies that affect the County's program. All such amendments, revisions, and modifications shall also be approved by the Critical Area Commission as established in § 8-1809 of the Natural Resources Article of the Annotated Code of Maryland. No such amendment shall be implemented without approval of the Critical Area Commission. Standards and procedures for Critical Area Commission approval of proposed amendments are as set forth in Critical Area Law § 8-1809(i) and § 8-1809(d), respectively.

Comprehensive reviews. The County will review its entire program and propose any necessary amendments to its entire program, including Critical Area maps, at least every six years. The anniversary of the date that the program became effective shall be used to determine when the review shall be completed. Within 60 days after the completion of the review, the County will send the following information in writing to the Critical Area Commission:

A statement certifying that the required review has been accomplished;

A necessary requests for program amendments, program refinements, or other matters that the County wishes the Critical Area Commission to consider;

An updated resource inventory; and

A statement quantifying acreages within each land classification, the growth allocation used, and the growth allocation remaining.

Zoning Map amendments. Except for program amendments or program refinements developed during a six-year comprehensive review, a Zoning Map amendment may only be granted by the County Council upon proof of a mistake in the existing zoning. This requirement does not apply to proposed changes to a Zoning Map that meet the following criteria:

Are wholly consistent with the land classifications in the adopted program; or

Propose the use of growth allocation in accordance with the growth allocation provisions of this chapter.

Process. When an amendment is requested, the applicant shall submit the amendment to the DP&Z for review and research. Upon completing findings of fact, these documents shall be forwarded to the County Council. The County Council shall hold a public hearing at which parties of interest and citizens shall have an opportunity to be heard. At least 14 days' notice of the time and place of such hearing shall be published in a newspaper of general circulation in the County. After the County Council approves an amendment, it shall forward its decision and applicable ordinances and resolutions along with the amendment request to the Critical Area Commission for final approval.

Critical Area commission review.

§ 68-19 Water-dependent facilities.

[Reference: COMAR 27.01.03.]

Applicability. The provisions of this section apply to those structures or works associated with industrial, maritime, recreational, educational, or fisheries activities that require location at or near the shoreline within the buffer. An activity is water-dependent if it cannot exist outside the buffer and is dependent on the water by reason of the intrinsic nature of its operation.

Identification.

Water-dependent facilities include, but are not limited to, ports, the intake and outfall structures of power plants, water-use industries, marinas and other boat docking structures, public beaches and other public water-oriented recreation areas, and fisheries activities.

Excluded from this regulation are individual private piers installed or maintained by riparian landowners, and which are not part of a subdivision that provides community piers.

General policies. The policies of the DP&Z with regard to water-dependent facilities shall be to limit development activities in the buffer to those that are water-dependent and provide by design and location criteria that these activities will have minimal individual and cumulative impacts on water quality and fish, wildlife, and plant habitat in the Critical Area.

Standards. The following standards shall apply to new or expanded development activities associated with water-dependent facilities:

New or expanded development activities may be permitted in the buffer in the intensely developed areas and limited development areas, provided that it can be shown:

That they are water-dependent;

That the project meets a recognized private right or public need;

That adverse effects on water quality, fish, plant and wildlife habitat are minimized;

That, insofar as possible, non-water-dependent structures or operations associated with water-dependent projects or activities are located outside the buffer; and

That the facilities are consistent with an approved local plan as set forth below.

Except as otherwise provided in this program, new or expanded development activities may not be permitted in those portions of the buffer which occur in resource conservation areas.

Implementation. Applicants for new or expanded water-dependent facilities in intensely developed areas or limited development areas shall set out in the application how the above requirements are met. Applicants for water-dependent facilities in a resource conservation area, other than those specifically permitted herein, must apply for a portion of the County's growth allocation as set forth in this chapter.

Evaluating plans for new and expanded water-dependent facilities. The DP&Z shall evaluate on a case-by-case basis all proposals for expansion of existing or new water-dependent facilities. The County shall work with appropriate state and federal agencies to ensure compliance with applicable regulations. The following factors shall be considered when evaluating proposals for new or expanded water-dependent facilities:

That the activities will not significantly alter existing water circulation patterns or salinity regimes;

That the water body upon which these activities are proposed has adequate flushing characteristics in the area;

That disturbance to wetlands, submerged aquatic plant beds, or other areas of important aquatic habitats will be minimized;

That adverse impacts to water quality that may occur as a result of these activities, such as non-point-source runoff, sewage discharge from land activities or vessels, or from boat cleaning and maintenance operations, is minimized;

That shellfish beds will not be disturbed or be made subject to discharge that will render them unsuitable for harvesting;

That dredging shall be conducted in a manner, and using a method which causes the least disturbance to water quality and aquatic and terrestrial habitats in the area immediately surrounding the dredging operation or within the Critical Area, generally;

That dredged spoil will not be placed within the buffer or elsewhere in that portion of the Critical Area which has been designated as a habitat protection area except as necessary for:

Backfill for permitted shore erosion protection measures;

Use in approved vegetated shore erosion projects;

Placement on previously approved channel maintenance spoil disposal areas; and

Beach nourishment.

That interference with the natural transport of sand will be minimized; and

That disturbance will be avoided to historic areas of waterfowl staging and concentration or other habitat protection areas identified in the habitat protection area sections of this chapter.

Availability of information. The information necessary for evaluating the above factors, if not available locally, shall be obtained from appropriate state and federal agencies.

Industrial and port-related facilities. [Reference: COMAR 27.01.09.01-8.]

New, expanded or redeveloped industrial or port-related facilities and the replacement of these facilities may be permitted only in those portions of intensely developed areas that have been designated as modified buffer areas as described in this chapter and are subject to the provisions set forth in § 68-25.

Marinas and other commercial maritime facilities. New, expanded or redeveloped marinas may be permitted in the buffer within intensely developed areas and limited development areas subject to the requirements set forth in this section. New marinas or related maritime facilities may not be permitted in the buffer within resource conservation areas, except as provided in this section. Expansion of existing marinas may be permitted by the DP&Z within resource conservation areas, provided that it is sufficiently demonstrated that the expansion will not adversely affect water quality, and that it will result in an overall net improvement in water quality at or leaving the site of the marina. New and existing marinas shall meet the sanitary requirements of the Department of the Environment as required in COMAR 26.04.02. New marinas shall establish a means of minimizing the discharge of bottom wash waters into tidal waters.

Community piers. New or expanded community marinas and other noncommercial boat-docking and storage facilities may be permitted in the buffer subject to the requirements in this section of the Zoning Ordinance,[1] provided that:

These facilities may not offer food, fuel, or other goods and services for sale and shall provide adequate and clean sanitary facilities;

The facilities are community-owned and established and operated for the benefit of the residents of a platted and recorded riparian subdivision;

The facilities are associated with a residential development approved by the County for the Critical Area and consistent with all state requirements and program requirements for the Critical Area;

Disturbance to the buffer is the minimum necessary to provide a single point of access to the facilities; and

If community piers, slips, or moorings are provided as part of the new development, private piers in the development are not allowed.

Editor's Note: See Ch. 155, Zoning, Attachment 1.

Number of slips or piers permitted. The number of slips or piers permitted at the facility shall be the lesser of Subsection K(1) or (2) below:

One slip for each 50 feet of shoreline in the subdivision in the intensely developed and limited development areas and one slip for each 300 feet of shoreline in the subdivision in the resource conservation area; or

A density of slips or piers to platted lots or dwellings within the subdivision in the Critical Area according to the following schedule:

Table 68-19K(2)
Number of Slips Permitted
Platted Lots or Dwellings in Critical Area	Slips
Up to 15	1 for each lot
16 to 40	15 or 75%, whichever is greater
41 to 100	30 or 50%, whichever is greater
101 to 300	50 or 25%, whichever is greater
Over 300	75 or 15%, whichever is greater

Public beaches and other public recreation or education areas. Public beaches or other public water-oriented recreation or education areas, including, but not limited to, publicly owned boat launching and docking facilities and fishing piers may be permitted in the buffer in intensely developed areas. These facilities may be permitted within the buffer in limited development areas and resource conservation areas, provided that:

Adequate sanitary facilities exist;

Service facilities are, to the extent possible, located outside the buffer;

Permeable surfaces are used to the extent practicable, if no degradation of groundwater would result;

Disturbance to natural vegetation is minimized; and

Areas for passive recreation, such as nature study, and hunting and trapping, and for education, may be permitted in the buffer within resource conservation areas if service facilities for these uses are located outside of the buffer.

Research areas. Water-dependent research facilities or activities operated by state, federal, or local agencies or educational institutions may be permitted in the buffer, if non-water-dependent structures or facilities associated with these projects are, to the extent possible, located outside of the buffer.

Fisheries activities. Lands and water areas with high aquacultural potential will be identified by the DP&Z in cooperation with the state when applications for new or expanded fisheries or aquaculture facilities in these areas are submitted to the County. These areas are encouraged for that use and, if so used, should be protected from degradation by other types of land and water use or by adjacent land and water uses. Commercial water-dependent fisheries, including but not limited to structures for crab shedding, fish off-loading docks, shellfish culture operations and shore-based facilities necessary for aquaculture operations and fisheries activities, may be permitted in the buffer in intensely developed areas, limited development areas and resource conservation areas.

§ 68-20 Shore erosion protection.

[Reference: COMAR 27.01.04 and COMAR 26.24.04.]

Applicability. Shore erosion protection includes nonstructural shoreline stabilization measures and structural shoreline stabilization measures authorized by Maryland Department of the Environment, the Board of Public Works, or the Army Corps of Engineers, as appropriate. The provisions of this section shall apply to areas of the shoreline that are mapped as modified buffer areas and areas of the shoreline that are not mapped as modified buffer areas. The criteria set forth in § 68-20 are not intended to apply to those structures necessarily associated with water-dependent facilities as discussed in § 68-19.

Process. The DP&Z shall review and approve all authorized shore erosion protection measures and accompanying buffer management plans and sediment and erosion control plans prior to start of construction.

Upon authorization by Maryland Department of the Environment, an applicant for a shore erosion protection measure shall submit an application to the DP&Z containing the following information:

Photographs of the erosion problem;

The specific location of the site indicated on a 7 1/2 Minute USGS Topographic Quadrangle Map;

Soil type and erodibility;

The proposed and existing land use; and

Appropriate authorization from the Maryland Department of the Environment and the United States Army Corps of Engineers.

The application shall include a buffer management plan per the requirements of § 68-25F. The plan will identify all associated disturbance, including grading and clearing, above mean high water.

Mapping. As a part of this Critical Area Program, Dorchester County, with assistance from the state, shall designate and map the following shoreline areas:

Shoreline areas where no significant shore erosion occurs;

Other eroding areas where nonstructural measures would be a practical and effective method of erosion control; and

Eroding areas where only structural measures would provide effective and practical erosion control.

Policies. The following policies are intended to accomplish the following objectives:

Provide that structural control measures only be used in areas designated § 68-20C(3), above;

Provide that, where structural erosion control is required, the measure that best provides for conservation of fish and plant habitat, and which is practical and effective, shall be used;

Provide that nonstructural measures be utilized in areas of erosion as described in § 68-20C(2) and (3), above;

Provide that structural erosion measures not be encouraged in areas where no significant erosion occurs; and

Provide that, if significant alteration in the characteristics of a shoreline occurs, the measure that best fits the change may be used for sites in that area.

Dorchester County shall provide the Commission with the approved buffer management plan for a shore erosion control measure in accordance with COMAR 26.24.04.01-3 and 27.01.09.01-3.

Mitigation. Most shore erosion control projects involve disturbance to the shoreline and the 100-foot buffer. Applicants shall be required to mitigate for this disturbance in accordance with the provisions of § 68-25. Shore erosion control projects that are installed completely from the water and involve only offshore measures, such as breakwaters, may not require mitigation if the applicant demonstrates that the construction does not affect the buffer.

§ 68-21 Commercial timber harvesting.

[Reference: COMAR 27.01.05.]

General policies. A goal of the Critical Area Program is to maintain or increase the lands in forest cover, because forests provide protection of the water quality and habitat values of the Chesapeake Bay and its tributaries.

Process. Landowners proposing to harvest timber within any one year interval and affecting one or more acres in the Critical Area shall submit a timber harvest plan. This plan shall be prepared by a registered professional forester. The timber harvest plan shall be reviewed and approved by the Department of Natural Resources and the Dorchester County Forestry Board. The approved plan is valid for three years from the date on which the Forestry Board signs it. The plan shall be filed with the County Soil Conservation District and the approved plan shall be sent to the DP&Z prior to beginning timbering operations.

Timber harvest plan contents. Plans shall include measures to protect surface and groundwater quality and identify whether the activities will disturb or affect habitat protection areas as identified in this chapter and shall incorporate protection measures for these areas as specified in that section. To provide for the continuity of habitat, the plans shall address mitigation through forest management techniques which shall include scheduling size, timing and intensity of harvest cuts, afforestation and reforestation.

Sediment control plans. In the Critical Area, any landowner who plans to harvest timber on an area which will disturb 5,000 square feet or more, including harvesting on agricultural lands, shall submit a sediment control plan. This plan is also required for any harvests which will cross perennial or intermittent streams. This plan shall be developed according to the state guidelines entitled "Standard Erosion and Sediment Control Plan for Harvest Operations." The operations shall be implemented in accordance with specifications set out by the Department of Natural Resources and enforced by the Department of the Environment and the Dorchester County Department of Public Works.

If cuts and fills are three feet or more, if grades for roads are 15% or more, or if landings are on slopes of 10% or more, then the landowner must get a custom sediment control plan for the operation. These are prepared by registered professional foresters and include controls necessary to prevent site erosion and to ensure site stabilization. This plan shall be submitted to the local Soil Conservation District for approval and notice of approval sent to the Department of Planning and Zoning.

If a custom sediment control plan is not required, a standard erosion and sediment control plan is available through the Soil Conservation District. The landowner shall provide the following information:

Location description;

Harvest operation description;

Sketch map of the property showing acres to be cleared;

Identification of the landowner, licensed timber harvest operator, and other operators or subcontractors.

Either the owner or the operator shall take responsibility for implementation of the sediment control plan or each subcontractor must file a separate plan.

The landowner must sign the agreement to certify that he understands the terms of the plan and is responsible for preventing erosion and sedimentation during the forest harvesting.

Buffer protection standards for timber harvests. Timber harvests are permitted in the buffer in accordance with the provisions of § 68-25M.

§ 68-22 Agriculture.

[Reference: COMAR 27.01.06.]

Purpose. The County's intent is to maintain agriculture and forestry as viable and productive land uses within the Critical Area. The County has identified agriculture and the protection of agricultural land uses and activities as a priority in the County's Comprehensive Plan. The County works cooperatively with the Soil Conservation District, the County Agricultural Land Preservation Advisory Boards, the Farm Bureau, and other appropriate agencies to promote sound land and water stewardship on agricultural lands.

General policies. The County shall follow all of the following policies with regard to agriculture in the Critical Area:

Assure that agricultural lands are identified and that programs are established for the Critical Area to maintain, where appropriate, agricultural lands in agricultural use, to the greatest extent possible.

Recognize that agriculture is a protective land use that should be properly managed so that it minimizes its contribution to pollutant loadings to the Bay and its tributaries.

Assure that the creation of new agricultural lands is not accomplished:

By diking, draining or filling of any class or subclass of palustrine wetlands, as described in this program, which have a seasonally flooded or wetter water regime, unless mitigation is accomplished in accordance with, as applicable, state and County regulations;

By clearing of forests or woodlands on soils with a slope greater than 15%; or on soils with a "K" value greater than .35 and slope greater than 5%;

If the clearing will adversely affect water quality or will destroy plant and wildlife habitat as defined in this chapter; or

By the clearing of existing natural vegetation within the buffer as defined in this chapter.

Assure that the drainage of nontidal wetlands for the purpose of agriculture be done in accordance with a soil conservation and water quality plan approved by the County Soil Conservation District. [Reference: COMAR 26.23.04.]

Assure that best management practices for the control of nutrients, animal wastes, pesticides and sediment runoff be used to protect the productivity of the land base and enhance water quality. These practices shall minimize contamination of surface and groundwater and, further, shall minimize adverse effects on plants, fish and wildlife resources.

Assure that animal feeding operations, including retention and storage ponds, feed lot waste storage and manure storage, minimize the contamination of water bodies.

Assure that agricultural activity permitted within the Critical Area use best management practices in accordance with a soil conservation and water quality plan approved by the County Soil Conservation District.

Performance standards for agriculture. The following performance standards shall be adopted for all land in agricultural use or to be converted to agricultural use within the Critical Area:

The County hereby incorporates the agricultural components of the State 208 Water Quality Plan into this program. These components shall be applicable to all agricultural activities in the Critical Area.

Soil conservation and water quality plans and best management practices shall be developed and implemented for those portions of farms which lie within the Critical Area. Local farmers shall cooperate with the local Soil Conservation District for approval of their proposed plans. Landowners who have signed up as Conservation District operators but who do not have a conservation plan prepared for them by the local Conservation District shall be allowed to continue to farm until a conservation plan is developed, provided that the goals of this program are being met.

A landowner shall select and implement, with the assistance of a technically trained soil conservation planner or technician, from among the several best management practices that minimize impacts to water quality, conserve fish, wildlife, and plant habitat, and integrate best with the farming operation.

Until such time as the farm plans are developed and implemented, farmers shall as a part of the program be encouraged to use the following practices:

Cover crops shall be planted to reduce erosion;

Nutrients shall be applied at the appropriate time and appropriate methods shall be used;

Reduced tillage (e.g., no till practices shall be utilized) where practical; and

Crop rotations shall be implemented where effective.

Agricultural activities in the buffer. Agricultural activities are permitted in the buffer in accordance with the provisions of § 68-25L.

§ 68-23 Surface mining in Critical Area.

[Reference: COMAR 27.01.07.]

Applicability. The provisions of this section apply to all existing and proposed operations engaged in the extraction or removal of minerals, sand, gravel, rock, stone, earth or fill and activities related to surface mining. These activities include, but are not limited to, operations engaged in processing minerals at the site, removal and mining when done for the purpose of prospecting, washing mined material, and loading and transporting mined material.

General policies. The Dorchester County Department of Public Works (DPW) shall assure that all available measures are taken to protect the Critical Area from all sources of pollution from surface mining operations, including but not limited to sedimentation, siltation, chemical and petrochemical use and spillage, and storage and disposal of waste, dusts and spoils. The DPW shall further assure that surface mining is conducted in a way to permit the reclamation of surface mining sites as soon as possible and to the extent possible.

Mineral resource plan and program. The DPW will develop and comply with a mineral resource plan and program for management if applicable.

Standards. Surface mining operation permits are issued by the Maryland Department of the Environment (MDE), and periodic site inspections of permitted areas are made to determine whether the conditions of the permit and the accompanying reclamation plan are being fulfilled. Local approvals and related permits for surface mining operations in the County in the Critical Area shall only be granted if the following conditions are met:

A reclamation plan shall be submitted as part of the permit application which specifies the use which is proposed to be made of the site following reclamation, the manner in which that soil and subsoil are to be conserved and restored, the specifications for surface gradient restoration suitable for the subsequent use, the proposed manner and type of revegetation or other surface treatment of affected areas and an acceptable schedule to the DPW for the implementation of reclamation measures. Reclamation is to occur as mining on each segment of a site is completed;

The operation will not have an unduly adverse effect on wildlife, forests, or fresh water, estuarine or marine fisheries;

The operator has provided applicable permits from all federal, state and local regulatory agencies responsible for air and water pollution and sediment control; and

Adequate consideration shall be given to:

The effects of the proposed action on the environment, including adverse and beneficial environmental effects that are reasonably likely if the proposal is implemented or if it is not implemented.

Measures that might be taken to minimize potential adverse environmental effects and maximize potential beneficial environmental effects, including monitoring maintenance, replacement, operation and other followup activities.

An applicant's previous experience with similar operations which indicates that the operation will not result in substantial deposits of sediment in stream beds or lakes, landslides, or other causes of water pollution.

Location of future sites. Presently most of the resource conservation area of the County's Critical Area is zoned for agricultural or conservation use. Surface mining is permitted in Agricultural Districts. Proposed new surface mining sites or expanded operations of existing sites shall comply with the following:

New surface mining operations are permitted within the Critical Area, provided that identification of appropriate post-excavation uses for this land, such as recreation, habitat restoration, open space use, or development, are accomplished according to the appropriate land management classification (IDA, LDA or RCA) and other applicable County and state codes and ordinances.

Areas such as the following shall not be used for surface mining:

Habitat protection areas and other important natural resource areas such as those of scientific value or areas where assemblages of rare species occur;

Areas where highly erodible soils exist;

Areas where the use of renewable resource lands would result in the substantial loss of long-range (25 years or more) productivity of forest and agriculture, or would result in a degrading of water quality or a loss of vital habitat;

Lands that are within 100 feet of the mean high-water line of tidal waters, tidal wetlands, or the edge of streams.

Surface mining operations shall operate under the following conditions:

Future wash plants, including ponds, spoil piles, and equipment, may not be located within the buffer as defined in this chapter;

Existing wash ponds shall be reclaimed as soon as possible after the cessation of a sand and gravel operation;

To the fullest extent possible, existing sand and gravel operations shall conduct their extraction activities so as to provide, at a minimum, a 100-foot buffer of natural vegetation between the operation and the mean high-water line of tidal waters or the edges of streams and tidal wetlands, whichever is further inland.

§ 68-24 Habitat protection.

[Reference: COMAR 27.01.09.]

Description. The habitat protection areas sections of the County's Critical Area Ordinance address protection of the following five habitats:

The 100-foot buffer;

Nontidal wetlands;

Threatened and endangered species and species in need of conservation;

Plant and wildlife habitat protection areas including nontidal wetlands; and

Anadromous fish propagation waters.

Identification. Maps illustrating the general location, extent and configuration of habitat protection areas in the County are on file with the DP&Z. They will be used as a "flagging" device to assist property owners, developers, any person proposing development activity, DP&Z and other agencies of the County government when reviewing development plans. While these maps give a general indication of the area, they do not excuse any property owner or operator from establishing to the satisfaction of the DP&Z, whether or not the property or activity will affect the element of habitat to be protected. At the time of development the applicant will be responsible for providing an on-site analysis and inventory.

§ 68-25 100-foot and expanded buffers.

[Reference: COMAR 27.01.09.01 though .01-8.]

Applicability and delineation. An applicant for a development activity or a change in land use shall apply all of the required standards for a minimum 100-foot buffer as described in this part.

§ 68-26 Modified buffer area provisions.

[Reference: COMAR 27.01.09.01-8.]

Description.

Section 27.01.09.01.C(8) of the Critical Area criteria permits Dorchester County to request an exemption of certain portions of the Critical Area from the buffer requirements where it can be sufficiently demonstrated that the existing pattern of residential, industrial, commercial, and recreational development in the Critical Area prevent the buffer from fulfilling the functions set forth in the criteria. The designation of these areas, formerly referred to as "buffer exemption areas (BEAs)," and are now referred to as "modified buffer areas (MBAs)" without any further action by County Council, must be approved by the Critical Area Commission.

The following provisions are intended to accommodate limited use of shoreline areas that have been mapped "modified buffer areas" while protecting water quality and wildlife habitat to the greatest extent possible. This section applies only to new development or redevelopment within 100 feet of tidal waters, tidal wetlands and tributary streams on lots of record as of December 1, 1985. The lots shall have been officially designated by the County, and approved by the Critical Area Commission, as modified buffer areas.

Commercial, industrial, institutional, recreational and multifamily residential development and redevelopment standards.

The purpose of this section is to guide the County in effectively implementing the modified buffer area provisions for commercial, industrial, institutional, recreational and multifamily residential development that achieve the water quality and habitat protection objectives of the policies for the buffer set forth in Section 27.01.09.01.B of the Critical Area Criteria.

New development or redevelopment activities, including structures, roads, parking areas and other lot coverage or septic systems, will not be permitted in the buffer unless the applicant can demonstrate that there is no feasible alternative and the Director of DP&Z or his designee finds that efforts have been made to minimize buffer impacts and the development shall comply with the following standards:

Development and redevelopment activities have been located as far as possible from mean high tide, the landward edge of tidal wetlands, or the edge of tributary streams.

Variances to other local setback requirements have been considered before additional intrusion into the buffer.

Convenience and expense were not factors considered when evaluating the extent of allowable impacts to the buffer.

New development, including accessory structures, shall minimize the extent of intrusion into the buffer. New development shall not be located closer to the water (or edge of tidal wetlands) than the local setback for the zoning district or 50 feet, whichever is greater. Structures on adjacent properties shall not be used to determine the setback line. The fifty-foot setback shall be maintained for all subsequent development or redevelopment of the property.

Redevelopment, including accessory structures, shall minimize the extent of intrusion into the buffer. Redevelopment shall not be located closer to the water (or edge of tidal wetlands) than the local setback for the zoning district or 25 feet, whichever is greater. Structures on adjacent properties shall not be used to determine the setback line. Existing structures located within the setback may remain or a new structure may be constructed on the footprint of an existing structure, or area of lot coverage. Opportunities to establish a twenty-five-foot setback should be maximized.

Development and redevelopment may not impact any habitat protection area (HPA) other than the buffer, including nontidal wetlands, other state or federal permits notwithstanding.

Modified buffer area designation shall not be used to facilitate the filling of tidal wetlands that are contiguous to the buffer or to create additional buildable land for new development or redevelopment.

No natural vegetation may be removed in the buffer except that required by the proposed construction.

Mitigation for development or redevelopment in the modified buffer area approved under the provisions of this subsection shall be implemented as follows:

Natural forest vegetation of an area twice the extent of the footprint of the development activity within the 100-foot buffer shall be planted on site in the buffer or at another location approved by the DP&Z.

Applicants who cannot fully comply with the planting requirement may use offsets to meet the mitigation requirement. Offsets include the removal of an equivalent area of existing lot coverage in the buffer, the construction of best management practices for stormwater, wetland creation or restoration, or other measures that improve water quality or habitat.

Applicants who cannot comply with either the planting or offset requirements in Subsection B(2)(i)[1] or [2] above shall pay into a fee-in-lieu program as follows:

Applicants shall submit to the DP&Z one cost estimate from a qualified landscape business for planting the equivalent of twice the extent of the development within the 100-foot buffer. The estimate shall include the cost of stock, planting, staking, mulching and a two-year guarantee.

The DP&Z shall determine the amount of the fee-in-lieu based on one cost estimate.

Any fees-in-lieu collected under these provisions shall be placed in an account that will assure their use only for projects within the Critical Area to enhance wildlife habitat, improve water quality, or otherwise promote the goals of the Critical Area Program. The funds cannot be used to accomplish a project or measure that would have been required under existing local, state, or federal laws, regulations, statutes, or permits. The status of these funds must be reported in Dorchester County's quarterly reports.

Any required mitigation or offset areas shall be protected from future development through an easement, development agreement, plat notes or other instrument and recorded among the land records of Dorchester County.

Single-family residential development and redevelopment standards. New development or redevelopment activities, including structures, roads, parking areas and other lot coverage or septic systems, will not be permitted in the buffer unless the applicant can demonstrate that there is no feasible alternative, and the DP&Z finds that efforts have been made to minimize buffer impacts. The development must comply with the following standards:

New development or redevelopment shall minimize the shoreward extent of intrusion into the buffer. New development and redevelopment shall not be located closer to the water (or the edge of tidal wetlands) than the MBA setback. The MBA setback on a site is determined by the principal structure on that site, the principal structures on adjacent properties, or the setback for the zoning district. In no case shall new development or redevelopment be located less than 50 feet from the water (or the edge of tidal wetlands).

Existing principal or accessory structures in the buffer may be replaced in the same location. Any increase in impervious area or lot coverage within the buffer shall comply fully with the requirements of this policy.

New accessory structures may be permitted in the buffer in accordance with the following setback requirements:

New accessory structures may be located closer to the water or edge of tidal wetlands than the principal dwelling only if it has been determined by the DP&Z or its designee that there are no other locations for the accessory structures.

The area of the accessory structures within the buffer shall be minimized and the cumulative total area of all new and existing accessory structures on the property shall not exceed 500 square feet within 50 feet of the water and 1,000 square feet total.

In no case shall new accessory structures be located less than 25 feet from the water (or edge of tidal wetlands).

Variances to other local setback requirements shall have been considered before additional intrusion into the buffer.

Development may not impact any HPAs other than the buffer, including nontidal wetlands, other state or federal permits notwithstanding.

No natural vegetation may be removed in the buffer except that required by the proposed construction. The applicant will be required to maintain any other existing natural vegetation in the buffer.

Modified buffer area designation shall not be used to facilitate the filling of nontidal wetlands that are contiguous to the buffer to create additional buildable land for new development or redevelopment.

Mitigation for development or redevelopment in the modified buffer areas approved under this section shall be implemented as follows:

Natural vegetation of an area twice the extent of the footprint of the development activity within the 100-foot buffer shall be planted on site in the buffer or other location as may be determined by the DP&Z. If it is not possible to carry out offsets or other mitigation within the Critical Area, any plantings or other habitat/water quality improvements should occur within the affected watershed.

Applicants who cannot comply with the planting requirements may use offsets to meet the mitigation requirements. Offsets may include the removal of an equivalent area of existing lot coverage within the buffer, the construction of best management practices for stormwater, wetland creation or restoration, or other measures that improve water quality or habitat.

Applicants who cannot comply with either the planting or offset requirements in Subsection C(8)(a) and (b) above shall pay into a fee-in-lieu program as follows:

Applicants shall submit to the DP&Z one cost estimate from a qualified landscape business for planting the equivalent of an area twice the extent of the footprint of the development activity within the 100-foot buffer. The estimate shall include the cost of stock, planting, staking, mulching and a two-year survival guarantee.

The DP&Z shall determine the amount of the fee-in-lieu based on one cost estimate.

Any required mitigation or offset areas shall be protected from future development through an easement, development agreement, plat notes, or other instrument and recorded among the land records of Dorchester County.

Notification requirements. All new commercial, industrial, institutional, recreational, multifamily residential development or redevelopment projects shall be submitted to the Critical Area Commission in accordance with COMAR 27.03.01.03. Mitigation plans shall be included as part of the project submission.

Review process. The DP&Z shall make written findings documenting that all the criteria in this section are met, including that the disturbance to the buffer is the least intrusion necessary. These findings shall be available to the Critical Area Commission upon request.

Modified buffer area mapping standards. The following standards shall apply for the mapping of new modified buffer areas:

Only lots of record as of December 1, 1985, are eligible for mapping as modified buffer areas (MBAs).

The parcel or lot being considered for MBA status shall contain a buffer that was significantly impacted by development at the time of program adoption and that prevent the buffer from fulfilling its functions.

Developed parcels or lots shall contain a buffer intrusion by the principal structures (excluding utilities or septic systems).

Undeveloped or vacant parcels or lots (i.e., infill) may be designated as a MBA if development within the buffer cannot be avoided based on the size of the parcel or lot, area of the parcel or lot within the buffer, or the surrounding pattern of development.

If only part of a parcel or lot meets the criteria for designation as a modified buffer area, then only portions of the parcel or lot shall be designated as a modified buffer area. The portion of the parcel designated as a modified buffer area will be subject to the modified buffer area requirements. Portions of the property that are not designated as a modified buffer area shall comply fully with the 100-foot buffer restrictions.

Any proposal by the County for designation of an area as a MBA shall include, at a minimum, a written evaluation and supporting reasons which demonstrate the degree to which the proposed MBA does not perform each of the following buffer functions:

Provide for the removal or reduction of sediments, nutrients, and potentially harmful or toxic substances in runoff entering the Bay and its tributaries;

Minimize the adverse effects of human activities on wetlands, shorelines, stream banks, and aquatic resources;

Maintain an area of transitional habitat between aquatic and upland communities;

Maintain the natural environment of streams; and

Protect riparian wildlife habitat.

§ 68-27 Nontidal wetlands.

[Reference: COMAR 27.01.09.02.]

Identification. Nontidal wetlands shall be identified, and the applicable standards applied, on all lands on which a development activity or a change in land use is proposed. Nontidal wetlands shall be delineated in the field by a professional qualified to perform delineations in accordance with the publication, "Federal Manual for Identifying and Delineating Jurisdictional Wetlands," published in 1989. The applicant shall be responsible for ensuring that nontidal wetlands are accurately identified and delineated.

General policies. Disturbance and alteration of nontidal wetlands should be avoided, and if unavoidable should be minimized because of the hydrologic and habitat functions they perform:

Provide for the removal or reduction of sediments, nutrients, and potentially harmful or toxic substances in runoff entering the Bay and its tributaries;

Facilitate the control, infiltration, and absorption of floodwaters associated with extreme high tides and storm events;

Minimize the adverse effects of human activities on waterways and aquatic resources;

Maintain an area of transitional habitat between aquatic and upland communities;

Maintain the natural environment of streams;

Provide wildlife habitat for wetland species.

Standards for nontidal wetland protection. In addition to the standards set forth in this chapter for protection of the buffer and expansion of the buffer for nontidal wetlands, development activity affecting nontidal wetlands shall comply with the following standards:

New development activity is prohibited in nontidal wetlands unless the development activity is water-dependent and requires access to a nontidal wetland as a central element of its basic function, or is not water-dependent and has no practicable alternative;

Where nontidal wetlands exist within the buffer, the 100-foot buffer shall be expanded to the upland limit of the nontidal wetland. This requirement is not intended to restrict the grazing of livestock in these wetlands;

The hydrologic regime and water quality of identified nontidal wetlands shall be protected by providing that development activities or other land disturbances in the drainage area of the wetlands shall minimize alterations to the surface or subsurface flow of water into and from the wetlands and not cause impairment of the water quality or the plant and wildlife and habitat value of the wetland;

New development activity will first avoid and then minimize adverse impacts to the nontidal wetland based on consideration of existing topography, vegetation, fish and wildlife resources, and hydrological conditions;

New development activity affecting nontidal wetlands must be designed so that it does not cause or contribute to a degradation of groundwaters or surface waters; and

Development activity permitted in accordance with these standards must be consistent with any comprehensive watershed management plan developed or approved by the Department under Environment Article, § 5-908, Annotated Code of Maryland.

Review process. Applicants for approval of development projects that involve disturbance or alteration to nontidal wetlands shall demonstrate to the appropriate approving authority:

That proposed impacts are unavoidable;

That alternative proposals were evaluated; and

That mitigation measures will be provided. Mitigation measures shall provide water quality benefits and plant and wildlife habitat equivalent to those of the wetland destroyed or altered and shall be accomplished, to the extent possible, on site or near the affected wetland.

§ 68-28 Threatened and endangered species; species in need of conservation.

[Reference: COMAR 27.01.09.03.]

Identification. The approximate location of rare, threatened and endangered species, and species in need of conservation are shown on a digitized geographic information system (GIS) data layer on file with the Dorchester County Department of Planning and Zoning. These maps will be used as a flagging device and do not carry the force of regulation. Final determinations will be made on the basis of field investigation by qualified persons.

General policies. The County shall provide protection for threatened and endangered species, those species in need of conservation and their habitats, which occur in the Critical Area.

Standards. The County shall provide for the protection of the known habitats of species in need of conservation, threatened and endangered species, and also habitats of these species that may be identified in the future.

If a development activity is proposed for a site within the Critical Area, then the DP&Z shall review the proposed activities on a case-by-case basis and seek technical advice from the Department of Natural Resources, Wildlife and Heritage Division. Based on the Department's recommendations, additional research and site analysis may be required to identify the location of threatened and endangered species and species in need of conservation on a site.

Pursuant to recommendations from the Department of Natural Resources, when development is proposed on or near sites which serve as, include, or are adjacent to a habitat of a threatened or endangered species or a species in need of conservation, the County will require that an applicant perform an appropriate ecological survey to verify the presence of the protected habitat or species.

If the presence of a protected habitat or species is confirmed, the County shall require that an applicant develop a habitat protection plan that provides for the protection and conservation of the species and habitats identified. In developing the plan, an applicant shall coordinate with the Department of Natural Resources to ensure that the plan is adequate to provide for long-term conservation and can be implemented on the specific site.

The applicant shall obtain approval of the habitat protection plan from the DP&Z or the appropriate designated approving authority. The specific protection and conservation measures included in the plan shall be considered conditions of approval of the project.

It is the policy of the County and the state policy to encourage cooperative management agreements with private landowners as the best way to preserve and protect critical habitats for threatened and endangered species and species in need of conservation. It is acknowledged that in the long term, easements or acquisition of the lands for preservation of these habitats should be sought. Management agreements, easements, and acquisition efforts shall be coordinated with the Maryland Department of Natural Resources and other appropriate public agencies, private organizations and affected landowners.

Public notice. The determination of the existence and extent of these habitats and protection areas shall result from a cooperative effort between the County and public agencies or private organizations. If the Secretary of the Department of Natural Resources designates additional species by regulation in the future, public hearings, as appropriate, shall be held to consider comments on these areas and the protection measures proposed for these species. The protection measures shall be adopted within 12 months of the date of the Secretary's designation.

The establishment of habitat protection areas shall not be intended to restrict or affect, beyond any existing local, state or federal laws or regulations or on private land, any private restrictions, such activities as noncommercial passive recreation (for example, hiking and nature photography), educational pursuits, scientific observation, or noncommercial hunting, trapping or fishing.

Development activities in areas of threatened or endangered species in need of conservation may be subject to other provisions and requirements of this program.

§ 68-29 Plant and wildlife habitat protection plan.

[Reference: COMAR 27.01.09.04.]

Description. The following plant and wildlife habitats shall be identified in the Critical Area and appropriately protected and conserved:

Colonial water bird nesting sites;

Historic waterfowl staging and concentration areas in tidal waters, tributary streams or tidal and nontidal wetlands;

Existing riparian forests (example: relatively mature forests of at least 300 feet in width which occur adjacent to streams, wetlands, or the bay shoreline and which are documented breeding areas);

Forest areas utilized as breeding areas by forest interior dwelling birds and other wildlife species (example: relatively mature forested areas within the Critical Area of 100 acres or more, or forest connected with such areas);

Other areas which may, in the future, be identified by the state and federal agencies as important plant and wildlife habitat areas;

Other plant and wildlife habitats determined to be of local significance; and

Natural heritage areas which have been designated;

General policies. The policies of the County regarding plant and wildlife habitat in the Critical Area shall be to:

Conserve wildlife habitat in the Critical Area;

Protect those wildlife habitats that tend to be least abundant or which may become so in the future if current land-use trends continue;

Protect those wildlife habitat types which are required to support the continued presence of various species;

Protect those wildlife habitat types and plant communities which are determined by the County to be of local significance;

Protect natural heritage areas; and

Protect and conserve nontidal wetlands.

Standards. The County's Critical Area Program and this chapter will serve to accomplish the goals of the Critical Area Program to protect water quality and wildlife habitat. In addition to the standards set forth in this chapter for the protection of the buffer, the following standards shall apply to new development and redevelopment within the Critical Area:

Any development or significant land use change of property located within the Critical Area of the County will require a site specific survey to determine the presence of any plant and wildlife habitat areas. The survey shall be submitted along with design plans and a written description of the measures the property owner proposes to take to protect the habitats identified. This information concerning habitats will be incorporated onto the resource inventory maps for future reference.

The County may seek additional information and comments from the Department of Natural Resources Wildlife and Heritage Division, and other appropriate agencies and adjacent jurisdictions.

When proposing development activities within riparian forests or forest areas utilized as breeding areas by forest interior dwelling birds, applicants shall review and utilize the guidance found in the Critical Area Commission publication entitled, "A Guide to the Conservation of Forest Interior Dwelling Birds in the Chesapeake Bay Critical Area," dated June 2000, and as may be subsequently amended. In addition, the Department of Natural Resources may make specific recommendations based on an evaluation of the site and the proposed development.

The County will encourage the conservation of rough areas, e.g., depressions, swales, nontidal wetlands or other areas unsuitable for development or agriculture as wildlife cover. Using cluster development, the developer shall leave these areas in natural vegetation or, where this is not feasible, replant with native vegetation.

For development activities in RCA and LDA, wildlife corridors shall be established and used to connect areas left in forest cover with any large forest tracts which are located outside of the area of the property being developed or subdivided. The area left in forest cover (at least 70% of the tract in LDAs or RCAs as required by this chapter) shall be adjacent to larger forest, not left as an isolated island of trees. Planting required as a mitigation measure shall also be adjacent to other habitat.

Buffer areas for colonial water bird (heron, egret, tern, and glossy ibis) nesting sites shall be established (if such birds are found to exist in the Critical Area) so that these sites are protected from the adverse impacts of development activities and from disturbance during the breeding season.

New water-dependent facilities shall be located to prevent disturbance to sites of significance to wildlife such as historic, aquatic staging and concentration areas for waterfowl.

Protection measures, including a buffer area, shall be established where appropriate, for other plant and wildlife habitat sites identified in this chapter.

Forested areas required to support wildlife species identified as threatened and endangered, or in need of conservation, shall be protected and conserved by developing management programs which have as their objective conserving the wildlife that inhabits or uses the areas. Development activities, or the clearing or cutting of trees which might occur in the areas, shall be conducted so as to conserve riparian habitat, forest interior wildlife species and their habitats. Management measures may include incorporating appropriate wildlife protection elements into timber harvest plans, forest management plans, cluster zoning or other site design criteria which provide for the conservation of wildlife habitats. Measures may also include soil conservation plans which have wildlife habitat protection provisions appropriate to the areas defined above, and incentive programs which use the acquisition of easements and other similar techniques.

When development activities, or the cutting or clearing of trees, occurs in forested areas, to the extent practical, corridors of existing forest or woodland vegetation shall be maintained to provide effective connections between wildlife habitat areas.

Those plant and wildlife habitats considered to be of local significance by the County shall be protected. Examples of these are those whose habitat values may not be of statewide significance but are of importance locally or regionally because they contain species uncommon or of limited occurrence in Dorchester County, or because the species are found in unusually high concentrations.

Natural heritage areas shall be protected from alterations due to development activities or cutting or clearing so that the structure and species composition of the areas are maintained. The following standards apply in natural heritage areas:

Development activities or cutting and clearing in natural heritage areas shall be prohibited unless an analysis is performed and measures proposed to mitigate any adverse impacts of the proposed activities. The analysis and mitigation measures shall be prepared by qualified professionals (e.g., ornithologists, zoologists, environmental engineers and planners) at the expense of the applicant and shall address the expected effects on the natural environment within the natural heritage area.

The analysis shall be submitted to the DP&Z which will then submit it to the State Department of Natural Resources for review and comment. Upon receiving said comment and, if appropriate, upon seeking the advice of expert consultants, the DP&Z shall find against or in favor of the activities or may make suggestions for changing the analysis and ask the applicant to resubmit the analysis. The initial review between the DP&Z and State Department of Natural Resources should be completed within 60 days of submission.

Development activities in areas of threatened or endangered species in need of conservation may be subject to other provisions and requirements of this program.

§ 68-30 Anadromous fish propagation waters.

[Reference: COMAR 27.01.09.05.]

Applicability. The provisions of this section apply to anadromous fish propagation waters. These are designated streams that are tributary to the Chesapeake Bay where spawning of anadromous fish occurs or has occurred.

Identification. The Department of Natural Resources has identified and mapped anadromous fish propagation waters as defined in this section, and these maps are available by contacting the Department.

General policies. The policies of the County with regard to anadromous fish propagation waters shall be to:

Protect the in-stream and stream-bank habitat of anadromous fish propagation waters;

Promote land use policies and practices in the watershed of spawning streams within the Critical Area which will minimize the adverse impacts of development on the water quality of the streams; and

Provide for the unobstructed movement of spawning and larval forms of anadromous fish in streams.

Standards. Within anadromous fish propagation watersheds, the following measures are required:

The installation or introduction of concrete riprap or other artificial surfaces onto the bottom of natural streams shall be prohibited unless it can be demonstrated that water quality and fisheries habitat can be improved.

Channelization or other physical alterations which may change the course or circulation of a stream, and thereby interfere with the movement of fish, shall be prohibited.

The County shall require each development activity that occurs within a watershed draining to anadromous fish propagation waters to fulfill the following objectives:

Minimize development activities or land disturbances within the watershed;

Maintain or, if practicable, improve water quality in affected streams or other water bodies;

Minimize to the extent possible the discharge of sediments into affected streams or other water bodies;

Maintain or, if practicable, increase the natural or native vegetation of the watershed and tree canopy over the streams;

The County shall ensure coordination and compliance with complementary state laws and regulations:

Prohibit the construction or placement of dams or other structures that would interfere with or prevent the movement of spawning fish or larval forms in streams or other designated water bodies. If practical, existing structures shall be removed; and
