[Amended 5-4-2010]
State law created the Critical Area regulations. The Critical Area Act recognizes that the land immediately surrounding the Chesapeake Bay and its tributaries has the greatest potential to affect water quality and wildlife habitat and thus designated all lands and water areas within 1,000 feet of tidal waters or adjacent tidal wetlands and all waters of and lands under the Chesapeake Bay and its tributaries to the head of the tide as indicated on State wetlands maps as the "Critical Area." General regulations are defined in Section 8-1.02. State law requires that the Critical Area be divided into three types of development areas based on land uses in existence when the regulations were adopted in 1985: Intensely Developed Areas, Limited Development Areas, and Resource Conservation Areas. Descriptions of and regulations for each of these three subareas are outlined in Sections 8-1.03, 8-1.04 and 8-1.05, respectively.
The following regulations apply to all lands in the Critical
Area. Also see Section 2-10.03.A, Purpose and Section 2-10.03.B, District
Boundaries.
A.
Limitation on Uses in the Critical Area
1.
Agriculture in the Critical Area is permitted subject to the following:
a.
The creation of new agricultural land in the Critical Area District
shall not be accomplished:
i.
By diking, draining, or filling of any class or subclass of
palustrine wetland, which have a seasonally flooded or wetter water
regime, unless the wetlands are mitigated on a one-to-one basis and
the appropriate permits are obtained from the Maryland Department
of the Environment;
ii.
By clearing of forests or woodland on soils with a slope greater
than 15 percent; or on soils with a "K" value greater than 0.35 and
slope greater than five percent;
b.
The drainage of non-tidal wetlands for the purpose of agriculture
shall be done in accordance with a Soil Conservation and Water Quality
Plan, approved by the Soil Conservation District.
c.
Best Management Practices for the control of nutrients, animal wastes,
pesticides, and sediment runoff shall 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.
d.
Animal feeding operations, including retention and storage ponds,
feed lot waste storage, and manure storage shall minimize the contamination
of water bodies.
e.
Agricultural activity permitted within the Critical Area shall use
Best Management Practices in accordance with a Soil Conservation and
Water Quality Plan approved by the Soil Conservation District.
2.
Non-Agricultural Uses in the Critical Area
a.
The following new development or redevelopment activities or facilities,
because of their intrinsic nature, or because of their potential for
adversely affecting habitats or water quality, are only permitted
in the Intensely Developed Area and only after the applicant has demonstrated
to all appropriate local and State permitting agencies that there
will be a net improvement in water quality of the adjacent body of
water. These activities include:
i.
Non-maritime heavy industry;
ii.
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
iii.
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.
b.
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:
[Amended 5-4-2010]
c.
Existing, permitted facilities of the type noted in 2(a) and (b)
of this sub-section shall be subject to the standards and requirements
of the Maryland Department of the Environment.
[Amended 5-4-2010]
B.
Critical Area Text and Map Amendments
[Amended 5-4-2010]
2.
The Critical Area District provisions of the Zoning Ordinance and
the Critical Area maps shall be comprehensively reviewed at least
every six years.
3.
An amendment to the LDA, LDA-3, RCA, or IDA boundaries may be granted only upon proof of a mistake in the zoning existing at the time of adoption of the Critical Area law in 1985 (Critical Area Law, Section 8-1809(h) or by the use of Growth Allocation as per Section 8-1.06.

D.
Delay of Critical Area Permits for Approved Variances
[Amended 5-4-2010]
1.
Permits for activities that require a Critical Area variance shall
not be issued until at least 30 days have passed beginning from the
date the Critical Area Commission receives notice of the decision
of the Board of Appeals.
A.
Purpose and Goals
1.
Purpose. The purpose of the IDA is to serve as the area where future
intense development activities shall be directed.
2.
Goals. The following goals will guide development in the IDA:
a.
Improve the quality of runoff from developed areas that enters the
Chesapeake Bay or its tributary streams;
b.
Accommodate additional development of the type and intensity designated
by the local jurisdiction provided that water quality is not impaired;
c.
Minimize the expansion of intensely developed areas into portions
of the Critical Area designated as Habitat Protection Areas
d.
Conserve and enhance fish, wildlife, and plant habitats, to the extent
possible, within intensely developed areas; and
e.
Encourage the use of retrofitting measures to address existing stormwater
management problems.
B.
Area Boundaries
Boundaries are as shown on the official Calvert County Critical
Area Map as IDA.
C.
Designation of Intensely Developed Areas
1.
Intensely Developed Areas are those areas within the Critical Area
District where residential, commercial, institutional, and/or industrial
developed land 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:
a.
Housing density is equal to or greater than four dwelling units per
acre;
b.
Industrial, institutional, or commercial uses are concentrated in
the area; or
c.
Public sewer and water collection and distribution systems are currently
serving the area and housing density is greater than three dwelling
units per acre.
2.
In addition, these features (1.a, b and c above) 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.
D.
Permitted Uses
Uses permitted in the underlying district are permitted as long
as they meet the conditions of Section 8-1.03.F.
E.
Special Exception Uses
Uses allowed as special exceptions may also be allowed as long
as they meet the conditions in Section 8-1.03.F.
F.
Criteria for Development in the Intensely Developed Area
1.
In addition to the development requirements contained in Articles 4, 5, 6 and 7 of this Zoning Ordinance, development and redevelopment shall be subject to the criteria contained in Section 8-1.08, Habitat Protection Areas.
2.
Stormwater:
a.
The Department of Planning and Zoning shall require, at the time
of development or redevelopment, technologies as required by applicable
State and local ordinances to minimize adverse impacts to water quality
caused by stormwater.
b.
In the case of redevelopment, if these technologies do not reduce
pollutant loadings by at least 10% below the level of pollution on
the site prior to redevelopment, then offsets as described in Section
8-1.03.F.2.d shall be provided to achieve this 10% reduction.
c.
In the case of new development, if these technologies do not reduce
pollutant loadings by at least 10% below the level of pollution on
the site prior to development, then offsets as described in Section
8-1.03.F.2.d and as determined by the County Engineer shall be used
if they reduce pollutant loadings by at least 10% of the pre-development
levels.
d.
Offsets may be provided either on or off site, provided that water
quality benefits are equivalent, that their 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. The offsets shall be approved by the County Engineer.
e.
The 10% reduction shall be calculated in the manner developed by
the Critical Area Commission in its document entitled "Critical Area
10% Rule Guidance Manual - Fall 2003", and as amended from time to
time.
f.
To meet the 10% reduction requirement, priority shall be given to
planting pervious areas with native vegetation. Examples of acceptable
offsets include but are not limited to:
[Amended 5-4-2010]
i.
Installing a new BMP in an existing urbanized area not already
served by a stormwater BMP (NOTE: No offset credits can be taken for
a new BMP that is already required under State Stormwater law).
ii.
Installing or financing an agricultural BMP in the Resource
Conservation Area.
iii.
Modifying an existing stormwater BMP to improve its pollutant
removal capability.
iv.
Modifying a public storm sewer network to trap pollutants (e.g.,
modify catchbasins, installing plate separators or swirl concentrators).
v.
Establishing a forested buffer strip in an existing developed
or cropped area where one does not presently exist.
3.
If practicable, permeable areas shall be established in native vegetation,
and whenever possible, redevelopment shall reduce existing levels
of pollution.
4.
Areas of public access to the shoreline, such as foot paths, scenic
drives, and other public recreational facilities, should be maintained
and are encouraged to be established within Intensely Developed Areas.
Such areas should be pervious where feasible.
5.
Ports and industries which use water for transportation and derive
economic benefits from shore access, shall be located near existing
port facilities. The Board of County Commissioners 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 Article 3, and Sections 8-2
and 9-7, and State and Federal regulations.
6.
To the extent practicable, future development shall use cluster development
as a means to reduce impervious areas and to maximize areas of natural
vegetation.
7.
When the cutting or clearing of trees in forests and developed woodland
areas is associated with current or planned development activities,
the following are required and require approval from the Department
of Planning and Zoning:
[Amended 5-4-2010]
A.
Purpose and Goals
1.
Purpose. The purpose of the LDA and LDA-3 is to serve as areas for
low or moderate intensity development.
2.
Goals. The following goals will guide development in the LDA:
a.
Maintain or, if possible, improve the quality of runoff and ground
water entering the Chesapeake Bay and its tributaries;
b.
Maintain, to the extent practicable, existing areas of natural habitat;
and
B.
Area Boundaries
Boundaries are as shown on the official Calvert County Critical
Area Map as LDA or LDA-3.
C.
Designation of Limited Development Areas
Limited Development Areas are those areas within the Critical
Area District which are currently developed in low or moderate intensity
uses. They also contain areas of natural plant and animal habitats,
and 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:
1.
Housing density ranging from one dwelling unit per five acres up
to four dwelling units per acre;
2.
Areas not dominated by agriculture, wetland, forest, barren land,
surface water, or open space;
3.
Areas meeting the conditions of Section 8-1.03.C.1, but not Section
8-1.03.C.2;
4.
Areas having public sewer or public water, or both.
D.
Density Limitation
1.
In the LDA, the maximum density is four dwelling units per acre.
If the primary zoning district is more restrictive, then those regulations
apply.
2.
All properties which are designated LDA-3 shall have a minimum lot size of three acres except for those one-acre lots created under Section 5-1.02 of the Zoning Ordinance which can not be accommodated outside of the Critical Area and those created under the residential cluster development Section 5-2.01 of the Zoning Ordinance.
E.
Permitted Uses
Uses permitted in the underlying district are permitted as long
as they meet the conditions of Section 8-1.04.G.
F.
Special Exception Uses
Uses allowed as special exceptions may also be allowed as long
as they meet the conditions in Section 8-1.04.G.
G.
Criteria for Development, Redevelopment, and Maintenance
In addition to State law and the development requirements contained
in Articles 4, 5, 6 and 7 of this Ordinance, the following regulations
shall apply:
1.
For development and redevelopment, the owner or agent of the owner
is required to identify and locate any environmental or natural features
described in this Section, and shall meet all of the following standards
of environmental protection:
a.
Criteria as required for the Habitat Protection Areas in Section 8-1.08 and those for the Water-Dependent Facilities in Section 9-7.
b.
Roads, bridges, or utilities in any portion of the Critical Area shall not be located in habitat protection area (Section 8-1.08 and COMAR 27.01.09), unless there is no feasible alternative. If the location of a road, bridge or utility in a habitat protection area is authorized under Section 8-1.04.G.1.b. above, the design, construction, and maintenance of the road, bridge or utility shall be conducted so as to:
[Amended 5-4-2010]
i.
Provide maximum erosion protection;
ii.
Minimize negative impact on wildlife, aquatic life, and their
habitats;
iii.
Maintain hydrologic processes and water quality;
iv.
Reduce or maintain existing levels of flooding attributable
to the development activity;
v.
Retain tree canopy so as to maintain stream water temperature
within normal variation;
vi.
Provide a natural substrate for streambeds; and
vii.
Minimize adverse water quality and quantity impacts of stormwater.
c.
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 offsite habitats. The
wildlife corridor system may include Habitat Protection Areas. The
establishment of conservation easements, restrictive covenants, or
similar instruments through which the corridor is preserved by public
or private groups, including homeowners associations, nature trusts,
and other organizations is required before final approval of the site
plan or subdivision may be granted.
d.
Development on slopes greater than or equal to 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 in Section 8-1.04 of this Ordinance. For new subdivisions, slopes greater than or equal to 15% shall be platted as "steep slope conservation areas" unless a variance has been granted to disturb these slopes.
[Amended 5-4-2010]
e.
To reduce stormwater runoff, lot coverage shall be limited as described
below:
[Amended 5-4-2010]
i.
In general, lot coverage is limited to 15% of a lot or parcel.
ii.
If a parcel or lot existed on or before December 1, 1985 in
the Chesapeake Bay Critical Area and is one-half acre or less in size,
then the lot coverage is limited to 25% of the lot or parcel.
iii.
For lots of one acre or less in size, as part of a subdivision
approved after the adoption of this amendment (05/4/2010), the lot
coverage shall be limited to 15% of the entire parcel being subdivided.
The lot coverage on each lot may exceed 15% as long as the lot coverage
over the entire parcel being subdivided does not exceed 15%.
iv.
Lots created after December 1, 1985 or properly permitted in
accordance with this ordinance and impervious surface policies in
effect prior to July 1, 2008 may be considered "legally non-conforming"
for purposes of lot coverage requirements.
v.
Lot coverage limits do not apply to a manufactured home community
that was in residential use on or before December 1, 1985 in the Critical
Area.
vi.
A walkway or stairway through the Buffer that provides direct
access to a pier is not included in lot coverage calculations.
vii.
There is no allowable, by right, percentage of lot coverage
within the 100-Foot Buffer. Exceptions include projects defined as
water-dependent facilities, projects in a Special Buffer Management
Area, and variances granted by the Board of Appeals.
viii.
Addition or alteration of any lot coverage including but not
limited to sidewalks, paving of driveways, construction of sheds,
decks, etc. requires either a grading exception, grading permit, or
building permit.
ix.
For grandfathered lots of record
that predate the Critical Area Program, a local government may allow
a property owner to exceed the lot coverage limits outlined above
and comply with the lot coverage limits set forth in the table below
if the following requirements are met:
(1)
Lot coverage associated with new development activities has
been minimized;
(2)
Water quality impacts associated with runoff from development
activities that contribute to lot coverage have been minimized; and
(3)
The property owner performs on-site mitigation or pays a fee-in-lieu
of mitigation as required by the local jurisdiction to offset potential
adverse water quality impacts.

x.
Grandfathering Provisions
(1)
The lot coverage provisions do not apply to development projects
for which a building permit was issued before July 1, 2008 as long
as construction is initiated and an inspection is performed by July
1, 2009. Impervious surface limits existing at the time of permit
approval do apply to these permitted projects.
(2)
Projects that are under design may be exempted from the strict
application of the lot coverage provisions if: An application for
a building permit or grading permit is filed by October 1, 2008, and
the permit is issued by January 1, 2010; or if an initial application
for development is filed by October 1, 2008, and the development plan
is approved by July 1, 2010. In addition, projects under design must
meet the following requirements: There must be a detailed lot coverage
plan, drawn to scale, showing the amounts of impervious surface area,
partially pervious surface area, and developed pervious surface area
for the project. The lot coverage plan must be approved by the local
government and maintained in the local jurisdiction's files, and the
development plan must remain valid in accordance with local procedures,
except that a moratorium or an adequate public facilities ordinance
cannot terminate the validity of an approved development plan for
purposes of lot coverage.
(3)
Development plans and lot coverage plans may be modified with
appropriate permits; however, the amounts of impervious surface, partially
pervious, and developed pervious areas cannot be increased beyond
set limits. Reductions in these areas are permitted.
(4)
Projects, including new subdivisions, for which an initial application
for development is filed by October 1, 2008 and approval is obtained
by July 1, 2010, but for which there is no approved lot coverage plan,
will be required to comply with all of the lot coverage provisions.
xi.
For lot coverage on split parcels
and growth allocation envelope sites, lot coverage shall be limited
as follows:
f.
Modifications in road standards to reduce potential impacts to the
site and Critical Area resources will be allowed where the reduced
standards do not affect safety.
g.
To reduce the extent of impervious areas and maximize areas of natural
vegetation, cluster development shall be encouraged as the preferred
development method.
h.
If less than 15 percent forest cover is established on proposed development
sites, these sites shall be planted to provide a forest or developed
woodland cover of at least 15 percent of the lot area within the Critical
Area.
2.
For the maintenance of forest and developed woodland in the Limited
Development Area, the following standards apply:
a.
The recommendations, when provided, of the Maryland Department of
Natural Resources shall be followed;
b.
Development activities shall be designed and implemented to minimize
destruction of forest and developed woodland vegetation; and a Developed
Woodland Management Plan (DWMP) shall be submitted to the Department
of Planning and Zoning. The Department of Planning and Zoning may,
at its discretion, send the DWMP to the Maryland Department of Natural
Resources for review and comment. The DWMP shall include methods for:
[Amended 5-4-2010]
i.
Minimizing forest loss; and
ii.
Maintaining the health of the existing or remaining forest;
and
iii.
Maintaining the functions of the forest or developed woodland
area relative to removing stormwater, preventing flooding, providing
habitat, controlling runoff and the uptake of nutrients and other
pollutants; and
iv.
Removal or inhibition of invasive species; and
v.
Mitigation as per Section 8-1.04.G.3.
3.
For the cutting or clearing of natural vegetation in forests and
developed woodland areas within the Limited Development Area, a permit
is required and the following criteria apply:
[Amended 5-4-2010]
a.
If no more than 6,000 square feet or 20 percent (whichever is greater)
of natural vegetation is cleared, replacement on an equal area basis
(1:1) is required. The remaining natural vegetation shall be designated
on the permit to remain in natural vegetation in perpetuity.
b.
If more than 6,000 square feet and more than 20 percent, but less
than 30 percent, of natural vegetation is cleared, replacement required
for the amount of clearing is one-and-a-half times the area of the
entire clearing (1 1/2: 1). The remaining natural vegetation
shall be designated on the permit to remain in natural vegetation
in perpetuity.
c.
Clearing of forest or developed woodland in excess of 30% is prohibited.
If Board of Appeals approval is obtained and more than 6,000 square
feet and more than 30 percent of natural vegetation is cleared, replacement
on a three-to-one (3:1) basis is required. The remaining natural vegetation
shall be designated on the permit to remain in natural vegetation
in perpetuity.
d.
No person shall cut or clear natural vegetation, or cause natural
vegetation to be cut or cleared before a permit for such cutting or
clearing has been issued by the Department of Planning and Zoning;
or in excess of the amount permitted in a permit issued by the Department
of Planning and Zoning.
e.
Clearing or alteration of vegetation inconsistent with this Section or unauthorized clearing or alteration of vegetation prior to having obtained the required permit shall be subject to fines and mitigation as described in Section 8-1.09.
f.
The area of vegetation planted to mitigate these requirements shall
be designed to replicate a natural forest and shall be planted in
accordance with Tables 8-1.4, 8-1.5 and 8-1.6. Guidance on allowed

7.
If reforestation exceeds 100 percent of the areal extent of forest
lost in the Critical Area, then the remaining funds may be used for
the following activities in priority order within the Critical Area:
8.
All forests designated on subdivision plats and site plans shall
be maintained to the extent practicable, through conservation easements,
restrictive covenants, or other protective instruments. For subdivisions,
forest areas to be retained shall be shown on the preliminary plan
and record plat as Forest Preservation Areas (FPA). For site plans
and plot plans, forest areas to be retained shall be shown on the
plan as Forest Preservation Areas. The following note shall be added
to all plans and plats: Forest Preservation Areas shall remain undisturbed
for water quality benefits and to provide habitat for wildlife. No
clearing or removal of vegetation shall be allowed in the Forest Preservation
Area unless a habitat protection plan is developed and approved by
the Department of Planning and Zoning and a grading permit or grading
exemption is also approved.
9.
The following regulations apply for cutting or clearing of forests
or developed woodland for utility corridors and percolation tests:
a.
For percolation tests, reforestation or payment of fees-in-lieu shall
be required for clearing corridors greater than 12 feet in width.
Clearing for percolation access should be limited and removal of trees
greater than six inches in diameter should be avoided. Clearing for
percolation test sites shall be limited to the number of test sites
required by the Health Department and shall not exceed a total of
2,500 square feet per test site (does not include area cleared for
access). If clearing will exceed 2,500 square feet for the percolation
test sites, then a grading permit and reforestation or payment of
fees-in-lieu shall be required.
b.
If these areas, which are exempt from reforestation and fees-in-lieu,
are later changed to another development use (e.g., access lanes to
percolation test sites become roadways) these areas will be considered
as having been forested in calculations of clearing limits and clearing
mitigation.
c.
Clearing in public utility rights-of-way should be minimized to the
greatest extent possible, may exceed 30 percent of the right-of-way,
and required mitigation will be on an equal area basis as described
in Section 8-1.04.G.3. Those portions of utility corridors in which
small trees and shrubs are maintained will be exempt from reforestation
requirements. Trees or their limbs that may strike utility lines or
structures may be removed without reforestation if small trees and
shrubs are maintained.
d.
A grading permit or grading exemption shall be obtained for the following
clearing activities associated with percolation test sites and utility
corridors:
i.
Total clearing for percolation test site areas per proposed
lot exceed 2,500 square feet.
ii.
Proposed utility corridors or percolation access lanes are greater
than 12 feet in width.
iii.
For any-sized utility corridor or percolation access lane proposed
in a habitat protection area such as a waterway Buffer or wetland
Buffer, wetland, rare, threatened, or endangered species habitat,
or forest dwelling bird habitat.
e.
Abandoned utility corridors, percolation access and percolation site
areas shall be allowed to naturally regenerate unless, at time of
development, these areas have been mitigated for by reforestation
or payment of fees-in-lieu.
i.
Though mitigation requirements for clearing for utility corridors
are as described in this Section, the limits to the percentage allowed
to be cleared do not apply to utility corridor rights-of-way. These
clearing limits do not apply to public road rights-of-way which are
external to subdivisions. Though clearing should be minimized, up
to 100 percent of these rights-of-way may be cleared. Mitigation for
clearing public road rights-of-way that are external to subdivisions
is on a one-for-one basis.
ii.
Offsite mitigation is allowed for public entities including
public utilities with the following conditions:
(a)
It is on a site within the Calvert County Critical Area (excluding
Chesapeake Beach and North Beach);
(b)
It is on property owned by the public entity;
(c)
The mitigation meets the requirements of the Calvert County
Critical Area Program in Section 8-1.04.G.3; and
(d)
A planting plan is submitted to and approved by the Department
of Planning and Zoning.
10.
The following regulations apply for development of slopes greater
than 15% and highly erodible soils:
a.
Super silt fence shall be installed and maintained around the disturbed
area until grading is stabilized with vegetative cover.
b.

uses at a density not to exceed one dwelling unit per 20 acres. Within
this limit of overall density, minimum lot sizes shall be in accordance
with the requirements of Article 5 of this Zoning Ordinance.
2.
In calculating the one-dwelling-unit-per-20-acre density of development
that is permitted on a parcel located within the Resource Conservation
Areas, the area of any private or State tidal and non-tidal wetlands
located on the property shall not be included.
3.
An accessory apartment will not be considered an additional dwelling
unit if the criteria under either paragraph 'a' or paragraph 'b' and
paragraphs 'c' through 'e' of this Section are met.
a.
The accessory apartment is located within the primary dwelling unit
or its entire perimeter is within 100 feet of the primary dwelling
unit; the accessory apartment does not exceed 900 square feet in total
enclosed area; and the accessory apartment is served by the same sewage
disposal system as the primary dwelling unit; or
b.
The accessory apartment is located within the primary dwelling unit;
by its construction, the accessory apartment does not increase the
amount of lot coverage already attributed to the primary dwelling
unit; and the accessory apartment is served by the same sewage disposal
system as the primary dwelling unit.
[Amended 5-4-2010]
c.
An additional dwelling unit meeting all the criteria of this Section
that is separate from the primary dwelling unit may not be subdivided
or conveyed separately from the primary dwelling unit.
d.

acreage of forest and woodland within the Resource Conservation Areas
does not decrease by:
f.
Nothing in this Section shall limit the ability of a participant
in the Agriculture Land Preservation Program to convey real property
with such a conservation easement to family members provided that
no such conveyance will result in a density greater than one dwelling
unit per 20 acres except as described in the following Section.
g.
For lot coverage on split parcels, lot coverage shall be limited
as follows:
[Amended 5-4-2010]
H.

[Amended 5-4-2010]
D.
Nothing in this regulation may be interpreted as altering any requirements
of this Ordinance for development activities for Water Dependent Facilities
and Habitat Protection Areas.
A.
Introduction. The State has designated certain areas and plant and
animal species as meriting special protection. They are: Critical
Area Buffers; nontidal wetlands; rare, threatened and endangered species
and species in need of conservation; plant and wildlife habitat; and
anadromous fish propagation waters.
B.
Boundaries. The boundaries for each type of habitat protection area
are described in the applicable Section.
C.
Criteria for Development. Habitat Protection Plans (HPP) are required
for all development activities, redevelopment, or maintenance in the
Habitat Protection Areas.
1.
If proposed development activities including clearing or cutting
of trees impact any known habitats of the types listed in this Section,
then a habitat protection plan shall be developed by the owner or
the owners' agent and approved by the Department of Planning and Zoning
using the expertise of the appropriate State and Federal agencies.
The programs should accomplish the following objectives:
a.
Establish Buffer areas for colonial water bird nesting sites so that
these sites are protected from the adverse impacts of development
activities and from disturbance during the breeding season;
b.
Provide that new water-dependent facilities do not disturb sites
of significance to wildlife such as historic, aquatic staging and
concentration areas for waterfowl;
c.
Provide protection measures, including Buffer areas where appropriate,
for the plant and wildlife habitat;
d.
Protect and conserve those forested areas required to support wildlife
species identified in this Section by developing management programs
which have as their objective, conserving the wildlife that inhabit
or use the areas. The programs should assure that development activities,
or the clearing or cutting of trees which might occur in the areas,
is conducted so as to conserve riparian habitat, forest interior wildlife
species, and their habitat. Management measures may include incorporating
appropriate wildlife protection elements into forest management plans,
and cluster zoning or other site design criteria which provide for
the conservation of wildlife habitat. Measures may also be included
in soil conservation plans which have wildlife habitat protection
provisions appropriate to the areas defined in this Section, and incentive
programs containing the acquisition of easements and other similar
techniques;
e.
Require that, when development activities or the cutting or clearing
of trees occur in forested areas, corridors of existing forest or
woodland vegetation be maintained to provide effective connections
between wildlife habitat areas;
f.
Protect, by appropriate means, those plant and wildlife habitats
designated and mapped by the County as Locally Significant Habitat.
Examples of these areas 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
the jurisdiction, or because the species are found in unusually high
concentrations; and
[Amended 5-4-2010]
g.
Protect Natural Heritage Areas from alteration due to development
activities or cutting or clearing so that the structure and species
composition of the areas are maintained.
2.
If the State proposes new habitat protective areas and protective
measures, they shall be adopted within one year in accordance with
procedures required by the Maryland Department of Natural Resources.
3.
Criteria for Habitat Protection Plans
a.
For Habitat Protection Areas, except the Critical Area Buffer areas
that do not have another Habitat Protection Area overlay, proposed
plans for development activities, clearing, or cutting of vegetation
in these areas shall be submitted to the Department of Planning and
Zoning for review and approval. The Department of Planning and Zoning
will forward copies of the proposed plans to the Critical Area Commission
and Natural Heritage Divisions of Maryland Department of Natural Resources
for review and comment. Criteria set by the State and Federal agencies
and County review staff shall be included in the Habitat Protection
Plan. The criteria shall be consistent with Section 8-1.08.C.1. The
applicant may appeal approval criteria to the Planning Commission.
The Habitat Protection Plan shall be recorded in the Land Records
of Calvert County and/or on a record plat.
b.
Critical Area Buffer areas (including expanded Buffer areas) that
do not have another Habitat Protection Area overlay, require a Buffer
Management Plan for development activities, clearing, or cutting of
vegetation in these areas. The Buffer Management Plan shall be submitted
to the Department of Planning and Zoning for review and approval and
shall address the following:
[Amended 5-4-2010]
i.
Minimization of the removal of vegetation;
ii.
Plant and wildlife habitat protection;
iii.
Reduction of the runoff of pollutants;
iv.
Required reforestation and/or afforestation including a planting
plan and other mitigation measures;
v.
Protection of the area during development activities.
The specific requirements of Buffer management Plans are given
in Section 8-1.08.D.3. Appeals of decisions made by the Department
of Planning and Zoning with regard to HPPs including Buffer Management
Plans for subdivisions and site plans may be appealed to the Planning
Commission. Appeals of decisions regarding HPPs including Buffer Management
Plans for other activities proposed in the Critical Area Buffer may
be appealed to the Board of Appeals.

D.
Critical Area Buffer
1.
Purpose. The purpose of the Buffer is to:
a.
Provide for the removal or reduction of sediments, nutrients, and
potentially harmful or toxic substances in runoff entering the Bay
and its tributaries;
b.
Minimize the adverse effects of human activities on wetlands, shorelines,
stream banks, tidal waters, and aquatic resources;
c.
Maintain an area of transitional habitat between aquatic and upland
communities;
d.
Maintain the natural environment of streams; and

Critical Area Buffer Description.
a.
The Buffer shall consist at a minimum of the area 100 feet landward
from the Mean High Water Line of tidal waters, the edge of the bank
of tributary streams, and the upland boundary of tidal wetlands and
shall be expanded as set out in paragraph 'b' of this Section.
[Amended 5-4-2010]
b.
The Buffer shall be expanded beyond 100 feet to include contiguous,
sensitive areas, such as steep slopes, hydric soils, or highly erodible
soils, (see paragraph 'd' of this sub-section), whose development
or disturbance may impact streams, wetlands, or other aquatic environments.
The minimum 100 foot Buffer shall be expanded to include the following
contiguous areas:
[Amended 5-4-2010]
i.
In the case of contiguous slopes of 15 percent or greater, the
Buffer shall be expanded four feet for every one percent of slope
[100'+ (4 percent * slope)], or to the top of the slope, whichever
is greater. The percent of slope will be measured as an average for
50 feet beyond the 100-foot Buffer. The expansion of the Buffer shall
be drawn perpendicular to the shoreline, tidal wetland or tributary
stream to be protected. The buffer shall not be expanded beyond a
drainage divide on grandfathered lots. The provisions of Section 8-1.08.D.3
apply to clearing within the expanded Buffer area;
[Amended 5-4-2012]
ii.
A nontidal wetland and its contiguous 50 ft. buffer;
iii.
A "Wetland of Special State Concern" and its contiguous 100-foot
buffer;
iv.
Highly erodible soils on a slope less than 15% and greater than
5% to the landward edge of the highly erodible soil or 300 feet, whichever
is less. The Buffer shall not be expanded beyond a drainage divide
on grandfathered lots;
[Amended 10-27-2010; 5-4-2012]
v.
Hydric soils to the landward edge of the hydric soil or 300
feet, whichever is less;
vi.
On a lot or parcel that was created before January 1, 2010,
a development activity may be allowed that impacts the expanded Buffer
for highly erodible soils on slopes less than 15% or hydric soils,
if:
[Amended 10-27-2010]
(a)
The development activity is in the expanded portion of the Buffer,
but not in the 100-foot Buffer or expanded Buffer for 15% slopes;
(b)
The entire Buffer occupies at least 75 percent of the lot or
parcel; and
(c)
Mitigation occurs at a 2:1 ratio based on the lot coverage of
the proposed development activity that is in the expanded Buffer.
c.
For subdivisions in the RCA and all projects in the RCA that require
a site plan and/or change in use which were submitted on or after
July 1, 2008, the Critical Area Buffer shall be 200 ft. landward from
the Mean High Water Line of tidal waters and tidal wetlands and a
100 ft. buffer from the edge of the bank of tributary streams. If
the Buffer is not forested, it shall be established in forest. The
Buffer shall be expanded beyond 200 ft. or 100 ft. for tributary streams
for the same reasons and in the fashion as described in Section 8-1.08.D.2.b.
The 200 ft. Buffer for these subdivisions may be reduced to no less
than 100 ft. or to the edge of the extended Buffer under the following
conditions:
i.
An application for subdivision of site plan approval is submitted
before July 1, 2008 and legally recorded by July 1, 2010;
ii.
The subdivision or site plan receives growth allocation;
iii.
The maximum density (1 dwelling unit/20 acres) cannot be achieved
on site using minimum lot sizes and standard County setbacks without
impacting the 200 ft. buffer. The minimum reduction in the buffer
necessary to accommodate the proposed development shall be applied.
iv.
An Intrafamily transfer allowed under Section 8-1.05.H of this
ordinance is precluded. The minimum reduction in the buffer necessary
to accommodate the proposed development shall be applied.
3.
Buffer Regulations
The following regulations shall govern activities within the
Buffer.
a.
The Buffer shall be maintained in natural vegetation and shall be
managed to achieve or enhance the functions stated in Section 8-1.08.D.1.
[Amended 5-4-2010]
i.
Except as authorized in Subsection "b" of this Section, disturbance
in the Buffer is prohibited.
ii.
Cutting, clearing or topping of trees and removal of existing
vegetation, including understory trees, shrubs and ground cover within
the Buffer is prohibited.
iii.
On areas of the property where land disturbance or clearing
comes within 50 feet of the Critical Area Buffer, the Buffer shall
be demarcated using snow fencing or silt fence prior to clearing,
grading, or construction and these protective devices shall remain
until construction is complete.
iv.
A 10-foot building setback shall be maintained from the edge
of the vegetated Buffers. The Zoning Officer may grant a reduction
of the setback after review and recommendation by the Environmental
Planner. The setback reduction may only be granted to allow activities
permitted in Section 8-2.05.C.6 and for construction of primary residences
which could not normally be built because of unusual lot configuration
or other site constraints.
v.
Before recordation of a final subdivision:
(a)
Permanent signs delineating the upland boundary of the Buffer
at a ratio of at least one sign per lot or per 200 linear feet of
shoreline, whichever is greater, shall be posted.
(b)
The signs shall be designed to be at least 11" wide and 15"
in height, placed at a height of 4.5 feet (but not attached to a tree),
and shall state "Critical Area Buffer-No clearing or disturbance permitted."
vi.
Concurrent with the recordation of a final plat, an applicant
shall record a protective easement for the Buffer.
vii.
When a Buffer Management Plan (BMP) is required, a final subdivision
application shall not be approved or a permit for a development activity
shall not be issued until the County has reviewed and approved the
BMP.
b.
Notwithstanding the prohibitions of paragraph 'a' above, the following
activities may be allowed with an approved Buffer Management Plan
and either a grading permit, grading exemption, or vegetation removal
permit. No permits are required for pruning limited to the lower one-third
of the height of the tree. Tree replacement is required at the ratios
given below.
[Amended 5-4-2010]
i.
Cutting of trees or removal of vegetation may be permitted where
necessary for the following purposes:
(a)
one access to the waterfront for a private pier (mitigation
ratio = 2:1) or
(b)
a boat ramp (mitigation ratio = 2:1), or
(c)
Other water dependent facility (mitigation ratio = 2:1),
(d)
Development in a Special Buffer Management Area consistent with
Section 8-1.08.D.4, or
(e)
to install or construct a shore erosion protection device or
measure, or a water-dependent facility, providing the device, measure,
or facility has received all necessary State and Federal permits (mitigation
ratio = 1:1).
No more than one access through the Buffer is permitted per
waterfront lot. A four-foot-wide access is allowed if the access is
for steps or a pathway; or a 12-foot- wide access is allowed for vehicular
access to a boat ramp.
|
ii.
Individual trees, living or dead, may be removed which are in
danger of falling and causing damage to dwellings or other structures,
or which are in danger of falling and therefore causing the blockage
of streams, or resulting in accelerated shore erosion (mitigation
ratio = 1:1, except that no mitigation or buffer management plan is
required for the removal of a tree within 10 feet of a cliff, which
is in danger of falling and has a diameter at four feet above the
ground of four inches or greater).
[Amended 5-4-2012]
iii.
Appropriate horticultural practices may be used to maintain
the health of individual trees, including removal of noxious, invasive,
and exotic species which impair the function and growth of a forested
Buffer. Inappropriate horticultural practices such as topping, girdling,
over pruning or severely damaging existing vegetation, are prohibited.
iv.
Other cutting techniques may be undertaken within the Buffer
and/or under the advice and guidance of the Department of Agriculture
and/or Natural Resources, if necessary to preserve the forest from
extensive pest or disease infestation, threat from fire, or to remove
invasive species (mitigation ratio = 1:1).
v.
Selective thinning and cutting may be approved by the Department
of Planning and Zoning if the Department determines that the function
of the Buffer will not be impaired.
vi.
Removal of vegetation for permitted development and redevelopment
activities may be permitted (mitigation ratio = 3:1 outside of Special
Buffer Management Areas and 2:1 in Special Buffer Management Areas).
vii.
As long as there is no removal of native vegetation, maintenance
of existing lawns and gardens and planting or replacement (within
30 days) of ornamental shrubs is allowed without permits. Planting
of native species is recommended.
c.

vii.
For substantial alteration, an area of the Buffer shall be established
equal to the total lot coverage; existing and newly approved.
viii.
All required buffer establishment will be bonded as described
in Section 8-1.04.G.4 and will require a Buffer Management Plan.
d.
Disturbance within the Critical Area Buffer based on an approved
variance from the Board of Appeals requires mitigation at a 3:1 ratio.
Mitigation for a violation (see Section 8-1.09.B) is at a 4:1 ratio.
[Amended 5-4-2010]
e.
New development, including structures, roads, parking areas and other
impervious surfaces, mining and related facilities, or septic systems,
shall not be permitted in the Buffer, except for those necessarily
associated with water-dependent facilities or for shore erosion control.

not disturb stream banks, tidal shorelines or other Habitat Protection
Areas as described in this Section.
[Amended 5-4-2010]
vi.
Where agricultural use of lands within the area of the Buffer
ceases and the lands are proposed to be converted to other uses, the
Buffer shall be established. In establishing the Buffer, management
measures shall be undertaken to provide forest vegetation that accomplishes
the Buffer functions set forth elsewhere in this Section.
g.
Commercial harvesting of trees by selection may be permitted to within
50 feet of the landward edge of the Mean High Water Line of tidal

in habitat protection areas unless it can be shown that these activities
or disturbances will not have or cause adverse impacts on these habitats;
[Amended 5-4-2010]
b.
At such time as an activity is proposed which might adversely affect
a habitat protection area, protection measures will be developed using
the expertise of the Maryland Department of Natural Resources and
other appropriate public agencies and private organizations.
[Amended 5-4-2010]
c.
The following protection measures are required as a minimum for Bald
Eagle nesting sites which have been verified by the Department of
Natural Resources and shall be addressed in a Habitat Protection Plan
submitted by the applicant:
[Amended 5-4-2010]
i.
A protection zone of one-quarter mile (1,320 feet) in radius
around each Bald Eagle nest is established.
ii.
Clearcutting or harvesting of timber (except limited timber
stand improvement) will not be allowed within one-quarter mile (1,320
feet) of the nest site during the nesting period, which is December
15th to June 15th.
iii.
Land clearing and construction within the protection zone will
not be allowed during the nesting season (December 15th to June 15th),
unless specifically approved by the Maryland Department of Natural
Resources.
iv.
Limited timber stand improvement and maintenance is allowed
between 660 feet and the outer limit of the protection zone outside
the nesting period (June 16th to December 14th).
v.
Limited timber stand improvement, maintenance and selective
cutting may be allowed between 330 feet and the outer protection zone
anytime after the nesting season.
vi.
No timber cutting, land clearing or building, road or trail
construction may be allowed within 330 feet of a verified nest.
vii.
If a Bald Eagle nest has not been used for three successive
nesting seasons, then any protective regulations applied to the specific
site may be removed after verification by the Maryland Department
of Natural Resources Forest Service that the nest was unused.
viii.
Existing agricultural activities which are in compliance with
this Section may continue in the protection zone though any intensification
of activity within the 330-foot zone during the nesting season shall
require a protection plan to be developed and approved by the Department
of Natural Resources.
[Amended 5-4-2010]
G.
Plant and Wildlife Habitat
1.
Purpose
The purpose of the Plant and Wildlife Habitat District is to:
a.
Conserve wildlife habitat in the Critical Area;
b.
Protect those wildlife habitats that tend to be least abundant or
which may become so in the future if current land-use trends continue;
c.
