ARTICLE I - PURPOSE AND ESTABLISHMENT
Certain areas of the Town of Topsham, Maine, are subject to periodic flooding, causing serious damages to properties within these areas. Relief is available in the form of flood insurance as authorized by the National Flood Insurance Act of 1968.
Therefore, the Town of Topsham, Maine, has chosen to become a participating community in the National Flood Insurance Program, and agrees to comply with the requirements of the National Flood Insurance Act of 1968 (P.L. 90-488, as amended) as delineated in this Floodplain Management Ordinance.
It is the intent of the Town of Topsham, Maine, to require the recognition and evaluation of flood hazards in all official actions relating to land use in the floodplain areas having special flood hazards.
The Town of Topsham has the legal authority to adopt land use and control measures to reduce future flood losses pursuant to Title 30-A MRSA, §§ 3001 through 3007, 4352, 4401 through 4407, and Title 38 MRSA § 440.
The National Flood Insurance Program, established in the aforesaid Act, provides that areas of the Town of Topsham having a special flood hazard be identified by the Federal Emergency Management Agency and that floodplain management measures be applied in such flood hazard areas. This section establishes a flood hazard development permit system and review procedure for development activities in the designated flood hazard areas of the Town of Topsham, Maine.
The areas of special flood hazard, Zones A and AE, for the Town of Topsham, Sagadahoc County, Maine, identified by the Federal Emergency Management Agency in a report entitled "Flood Insurance Study — Sagadahoc County, Maine," dated July 16, 2015, with accompanying "Flood Insurance Rate Map" dated July 16, 2015, with panels: 70F, 90F, 156F, 157F, 158F, 159F, 167F, 178F, 179F, 180F, 181F, 182F, 183F, 184F, 186F, 187F, 191F, 192F, 201F and 203F, derived from the county wide digital Flood Insurance Rate Map entitled "Digital Flood Insurance Rate Map, Sagadahoc County, Maine," are hereby adopted by reference and declared to be a part of this section.

The Board of Appeals may grant a variance from the requirements of this section consistent with state law and the following criteria:
A.
Variances shall not be granted within any designated regulatory floodway if any increase in flood levels during the base flood discharge would result.
B.
Variances shall be granted only upon:
1.
a showing of good and sufficient cause; and
2.
a determination that should a flood comparable to the base flood occur, the granting of a variance will not result in increased flood heights, additional threats to public safety, public expense, or create nuisances, cause fraud or victimization of the public or conflict with existing local laws or ordinances; and
3.
a showing that the issuance of the variance will not conflict with other state, federal or local laws or ordinances; and
4.
a determination that failure to grant the variance would result in "undue hardship," which in this subsection means:
a.
that the land in question cannot yield a reasonable return unless a variance is granted; and
b.
that the need for a variance is due to the unique circumstances of the property and not to the general conditions in the neighborhood; and
c.
that the granting of a variance will not alter the essential character of the locality; and
d.
that the hardship is not the result of action taken by the applicant or a prior owner.
C.
Variances shall only be issued upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief, and the Board of Appeals may impose such conditions to a variance as it deems necessary.
D.
Variances may be issued for new construction, substantial improvements, or other development for the conduct of a functionally dependent use, provided that:
1.
other criteria of Article IX and Article VI.K. are met; and
2.
the structure or other development is protected by methods that minimize flood damages during the base flood and create no additional threats to public safety.
E.
Variances may be issued for the repair, reconstruction, rehabilitation, or restoration of historic structures upon the determination that:
1.
the development meets the criteria of Article IX, Paragraphs A through D above; and
2.
the proposed repair, reconstruction, rehabilitation, or restoration will not preclude the structure's continued designation as an historic structure and the variance is the minimum necessary to preserve the historic character and design of the structure.
F.
Any applicant who meets the criteria of Article IX, Paragraphs A through E, shall be notified by the Board of Appeals in writing over the signature of the Chairman of the Board of Appeals that:
1.
the issuance of a variance to construct a structure below the base flood level will result in greatly increased premium rates for flood insurance up to amounts as high as $25 per $100 of insurance coverage;
2.
such construction below the base flood level increases risks to life and property; and
3.
the applicant agrees in writing that the applicant is fully aware of all the risks inherent in the use of land subject to flooding, assumes those risks and agrees to indemnify and defend the municipality against any claims filed against it that are related to the applicant's decision to use land located in a floodplain and that the applicant individually releases the municipality from any claims the applicant may have against the municipality that are related to the use of land located in a floodplain.
G.

It also includes, but is not limited to: accessory structures as provided for in Article VI.J., mining, dredging, filling, grading, paving, excavation, drilling operations, storage of equipment or materials, deposition or extraction of materials, public or private sewage disposal systems or water supply facilities that do not involve structures; and nonstructural projects such as bridges, dams, towers, fencing, pipelines, wharves, and piers.
National Geodetic Vertical Datum (NGVD) - means the national vertical datum, whose standard was established in 1929, which is used by the National Flood Insurance Program (NFIP). NGVD was based upon mean sea level in 1929 and also has been called "1929 Mean Sea Level (MSL)."
New Construction - means structures for which the "start of construction" commenced on or after the effective date of the initial floodplain management regulations adopted by a community and includes any subsequent improvements to such structures.
North American Vertical Datum (NAVD) - means the national datum whose standard was established in 1988, which is the new vertical datum used by the National Flood Insurance Program (NFIP) for all new Flood Insurance Rate Maps. NAVD is based upon vertical datum used by other North American countries such as Canada and Mexico and was established to replace NGVD because of constant movement of the earth's crust, glacial rebound, and subsidence and the increasing use of satellite technology.
100-Year Flood - see "base flood."
Recreational Vehicle - means a vehicle which is:
a.
built on a single chassis;
b.
400 square feet or less when measured at the largest horizontal projection, not including slideouts;

a.
means the channel of a river or other watercourse and the adjacent land areas that must be reserved in order to discharge the base flood without cumulatively increasing the water surface elevation more than one foot, and
b.
when not designated on the community's Flood Insurance Rate Map, it is considered to be the channel of a river or other watercourse and the adjacent land areas to a distance of one-half the width of the floodplain, as measured from the normal high water mark to the upland limit of the floodplain.
Riverine - means relating to, formed by, or resembling a river (including tributaries), stream, brook, etc.
Special Flood Hazard Area - see "area of special flood hazard."
Start of Construction - means the date the building permit was issued, provided the actual start of construction, repair, reconstruction, rehabilitation, addition, placement, substantial improvement or other improvement was within 180 days of the permit date. The "actual start" means either the first placement of permanent construction of a structure on a site, such as the pouring of slab or footings, the installation of piles, the construction of columns, or any work beyond the stage of excavation; or the placement of a manufactured home on a foundation. Permanent construction does not include land preparation, such as clearing, grading and filling; nor does it include the installation of streets and/or walkways; nor does it include excavation for basement, footings, piers, or foundations or the erection of temporary forms; nor does it include the installation on the property of accessory buildings, such as garages or sheds not occupied as dwelling units or not part of the main structure. For a substantial improvement, the "actual start of construction" means the first alteration of any wall, ceiling, floor, or other structural part of a building, or modification of any construction element, whether or not that alteration affects the external dimensions of the building.
Structure - means, for floodplain management purposes, a walled and roofed building. A gas or liquid storage tank that is principally above ground is also a structure.
Substantial Damage - means damage of any origin sustained by a structure whereby the cost of restoring the structure to its before damage condition would equal or exceed 50 percent of the market value of the structure before the damage occurred.
Substantial Improvement - means any reconstruction, rehabilitation, addition, or other improvement of a structure, the cost of which equals or exceeds 50 percent of the market value of the structure before the start of construction of the improvement. This term includes structures which have incurred substantial damage, regardless of the actual repair work performed. The term does not, however, include either:
a.
Any project for improvement of a structure to correct existing violations of state or local health, sanitary, or safety code specifications which have been identified by the local Code Enforcement Official and which are the minimum necessary to assure safe living conditions; or
b.
Any alteration of an historic structure, provided that the alteration will not preclude the structure's continued designation as an historic structure, and a variance is obtained from the community's Board of Appeals.
Variance - means a grant of relief by a community from the terms of a floodplain management regulation.
Violation - means the failure of a structure or development to comply with a community's floodplain management regulations.

2.
The above are minimum standards, and additional parking spaces shall be required if these prove to be inadequate.
3.
Where floor space is to be used in calculating the number of required parking stalls, gross floor space shall be used unless otherwise noted.
4.
In the LV, MV, VC, LI and R4 Zones, the first two residential spaces may be waived in calculating the total required parking for a mixed-use building or project.
(2) 
Alternative parking plan. A property owner or applicant for new or existing development approval may prepare an alternative parking plan in accordance with the provisions of this subsection. If the plan is approved by the Planning Board, the standards of the plan shall govern the provision of parking to serve the property rather than the minimum standards of § 225-27C(1). The provisions for an alternative parking plan as detailed in this section are applicable to all zoning districts.
(a) 
An alternative parking plan must conform to the following requirements:
[1] 
Be prepared by a professional engineer with experience in traffic and parking planning;
[2] 
Identify project uses and parking demand of each use. The parking demand shall include an analysis of peak and off-peak use including employees, customer/user demand, residential demand, and service demand (i.e., deliveries). The projection of parking demand may utilize either common industry standards such as the most current Institute of Transportation Engineers (ITE) parking demand manual or other applicable published parking standards that are applicable to the proposed use in a community like Topsham, or parking demand data from professional sources for similar uses in a community like Topsham;
[3] 
Identify surrounding land uses and their associated parking demand within 1,000 feet of the project site, including any available public parking, and quantify potential impacts to surrounding properties; and
[4] 
Include recommendations to ensure the long-term availability of off-street parking for the proposed use and protection from negatively impacting surrounding properties.
(b) 
The Planning Board shall review the alternative parking plan to determine if it will provide adequate parking to serve the uses without negatively impacting surrounding properties or public health, safety, and welfare. If the plan is approved, it shall be established as a condition of approval for any use relying on an alternative parking plan.
(c) 
If sufficient parking is not provided, the use or that portion of the use out of compliance shall be terminated or the property owner(s) will be subject to code enforcement in accordance with §§ 225-65 and 225-66.
D. 
Methods of meeting the parking requirements. A property owner or applicant for development approval may meet the minimum parking requirements established in Subsection C by one or more of the following methods:
(1) 
On-site exclusive use vehicle parking. Some or all of the required parking may be met with parking spaces and ancillary facilities meeting the requirements of § 225-27E.
(2) 
Shared use vehicle parking. Some or all of the required parking may be met through the use of shared parking spaces approved by the Planning Board, except that the use of shared parking facilities in the LV, VC, LI, BP2 and R4 Zones, and that portion of the CC that fronts on Route 201, does not require approval from the Planning Board. The joint use of a parking space by two or more principal buildings or uses is permitted when the property owner or applicant for development approval clearly demonstrates that such use will meet the intent of these parking requirements by reason of the variation in the times or days of maximum use by patrons, residents, or employees of the buildings or uses.
(3) 
Off-site vehicle parking. Required off-street parking in all districts shall be located on the same lot as the principal building or use except that the Planning Board may authorize off-street parking to be located within 1,000 feet of the lot on which the principal use is located, measured along lines of public access, where it cannot reasonably be provided on the same lot. Such parking areas shall be held under the same ownership or lease as the uses served and evidence of such control or lease shall be required. In cases in which off-street parking is provided upon leased land, the Code Enforcement Officer shall not issue a certificate of occupancy for such premises valid for a period longer than the duration of such lease.
(4) 
Public parking. The Planning Board may permit the required off-street parking for all nonresidential uses to be provided by municipal parking facilities, including public parking lots and on-street public parking spaces. The availability of public parking shall be shown to be representative of the off-street parking turnover or requirements of the particular business or use in question and shall take into consideration the needs of other businesses with similar demands upon such public parking spaces. No public parking spaces shall be considered as meeting the parking requirement unless located within 1,000 feet of the principal building as measured along lines of public access.
(5) 
Motorcycle, scooter, bicycle parking. When a property in a nonresidential use or a mixed use is required to provide more than 40 parking spaces, the property owner or applicant for development approval may meet up to 2.5% of the required parking spaces (or one space per 40 required spaces) with designated motorcycle, scooter, e-bike, or bicycle parking spaces. Any parking spaces for such use must be appropriately signed and must meet the following minimum size:
(a) 
Motorcycle: four feet by eight feet.
(b) 
Scooter: three feet by five feet.
(c) 
E-bike or bicycle: two feet by five feet or space on a bike rack or other facility for locking up the bike.
E. 
Parking design criteria (not applicable to single-family dwellings and duplexes).
(1) 
Parking areas. Parking areas with more than two parking spaces shall be arranged so that it is not necessary for vehicles to back into the street, except where on-street parking is allowed.
(2) 
Limits on vehicular entrances and exits. Each off-street parking area shall have no more than two openings onto the same street, each opening not to exceed 26 feet in width, except as further limited below:

Within the LI Zone, and that portion of the CC that fronts on Route 201, only one twenty-six-foot-wide access drive shall be allowed per 200 feet of frontage on Route 201. For lots without frontage on Route 201, only one twenty-six-foot-wide access drive shall be allowed per 100 feet of frontage.
(3) 
Entrances and exits shall be clearly identified by the use of signs, curb cuts and landscaping.
(4) 
Entrance/exit design shall be reviewed by the Town of Topsham Public Works Director, and be in conformance with the standards found in Chapter 184 of the Town of Topsham Code, as well as Maine Department of Transportation access management standards for size, location, sight distance, grade separation and possible future changes in highway alignment on any affected public roads.
(5) 
Interior vehicular circulation.
(a) 
Major interior travel lanes shall be designed to allow continuous and uninterrupted traffic movement.
(b) 
Enclosures, such as guardrails, curbs, fences, walls and landscaping, shall be used to identify circulation patterns of parking areas and to restrict driving movements diagonally across parking aisles, but not to reduce visibility of oncoming pedestrians and vehicles.
(6) 
Parking.
(a) 
Access to parking stalls shall not be from major interior travel lanes, and shall not be immediately accessible from any public way, except where on-street parking is allowed.
(b) 
Parking areas shall be designed to permit each motor vehicle to proceed to and from the parking space provided for it without requiring the moving of any other motor vehicles, except in the LV, MV, VC, LI, R4 and BP2 Zones where it can be demonstrated that stacked parking arrangements are feasible.

(f) 
In aisles utilizing diagonal parking, arrows shall be painted on the pavement to indicate proper traffic flow.
(g) 
Bumpers and/or wheel stops shall be provided where overhang of parked cars might restrict traffic flow on adjacent through roads, restrict pedestrian movement on adjacent walkways or damage landscape materials.
(h) 
Parking spaces shall be provided to conform to the number required in Table 225-27C(1), unless it can be demonstrated that fewer parking spaces for on-site parking can meet anticipated demand in accordance with § 225-27C(2) or an alternative parking plan approved by the Planning Board.
F. 
Additional requirements for commercial and industrial establishments.
(1) 
Access points from a public road to commercial and industrial operations shall be so located as to minimize traffic congestion and to avoid generating traffic on local access streets of a primarily residential character.
(2) 
All parking areas, driveways and other areas serving 10 or more vehicles shall be paved with bituminous concrete or an equivalent surfacing over a gravel subbase at least six inches in thickness, and shall have appropriate bumper or wheel guards where needed. Porous bituminous concrete and pavers designed for low-impact development applications approved by the Planning Board are acceptable alternatives. Gravel parking/work yard areas are allowed subject to Planning Board approval with the specific requirement that there will be no environmental impacts, such as dust, erosion or the tracking of gravel onto public rights-of-way.
(3) 
All driveway entrances and exits shall be kept free from visual obstructions higher than three feet above street level for a distance of 30 (as measured along the property line) feet measured along the intersecting driveway and street lines in order to provide visibility for entering and leaving vehicles.
(4) 
Loading facilities shall be located entirely on the same lot as the building or use to be served so that trucks, trailers and containers shall not be located for loading or storage upon any Town way.
(5) 
No loading docks shall be on any street frontage. Provision for handling all freight shall be on those sides of any buildings which do not face on any street or proposed streets.
G. 
Additional requirements for Mixed Use Limited (MUL) and Mixed Use Commercial (MUC) Zones:
(1) 
Driveways are not permitted within the setback areas of a lot except for access drives which are perpendicular to the setback for access to parking areas.
(2) 
All parking in the Mixed Use Limited Zone must be located to one side and/or the rear of buildings.

(a) 
A sidewalk with a minimum width of five feet, not including curbing, must be constructed along all public frontages of each developed property.
(b) 
Where sidewalks exist but are in substandard condition, they shall be repaired or replaced.
(c) 
All new or repaired sidewalks shall be constructed in conformance with § 185-7, Street design and pedestrian ways, and § 185-8, Minimum construction standards for public streets, sidewalks and utilities.
(d) 
An applicant may request a waiver from sidewalk installation requirements if they meet two or more of the following applicable waiver criteria:
[1] 
There is no reasonable expectation for pedestrian usage coming from, going to, and traversing the site.
[2] 
There is no sidewalk in existence or expected within 1,000 feet and the construction of sidewalks does not contribute to the development of pedestrian oriented infrastructure.
[3] 
A safe alternative walking route is reasonably available, for example, by way of a sidewalk on the other side of the street that is lightly traveled.

The reconstruction of the street is specifically identified and approved in the first or second year of the current Capital Improvement Plan (CIP) or has been funded through an earlier CIP or through other sources.
[5] 
The street has been constructed or reconstructed without sidewalks within the last 24 months.
[6] 
Strict adherence to the sidewalk requirement would result in the loss of significant site features related to landscaping or topography that are deemed to be of greater public value.
[7] 
Topography or other site features limit the constructability of a sidewalk.
(e) 
Applicants that receive Planning Board approval for a sidewalk waiver shall pay an in-lieu fee equal to the cost of providing a sidewalk upon his or her own frontage. The calculated costs must be reviewed and approved by Town staff and a payment must be made prior to the start of project construction.

Purpose: to allow context-sensitive flexibility in the review and application of certain land use performance standards for the protection of the environment, public health, safety, and general welfare. The Planning Board may grant a waiver from literal compliance with the mandatory provisions of this chapter if the applicant can demonstrate that:
(a) 
The deviation is unavoidable and represents the minimum feasible under the particular circumstances surrounding the proposal, and the grant of relief is reasonable, necessary and supports the general purpose and intent of the applicable provisions; or
(b) 
The literal enforcement of the provision(s) of the applicable provisions at issue is impracticable or will exact undue hardship because of peculiar conditions pertaining to the property in question; or
(c) 
That an alternative proposal will allow for equal or better results than those stated in the applicable provisions.
(2) 
The approval of a waiver shall not have the effect of making null and void the intent and purpose of this chapter. In the approval of a waiver, the Planning Board may impose such conditions as will, in its judgment, secure substantially the objectives of the applicable provisions of this chapter.
(3) 
Procedure for waiver.
(a) 
All requests for waivers shall be processed in accordance with the following: The approval of a waiver must be accompanied by a completed application form provided by the Topsham Planning Office, including, at a minimum, an explanation of how and to what extent the following conditions are addressed:
[1] 
The exception addresses Subsection I(1) above;
[2] 
The exception provides relief only to the minimum extent necessary;
[3] 
Other environmental features are not damaged in the process of protecting the regulated resources; and
[4]

[Added 5-15-2002 STM, Art. 20]
[Amended 5-15-1996 STM, Art. 31]
A. 
The landscape shall be preserved in its natural state insofar as practical, by minimizing tree removal and grade changes in keeping with the general appearance of neighboring developed areas. Landscaping shall be designed to soften, screen or enhance the physical design of structures and parking areas to avoid the encroachment of the proposed use on abutting land uses. All parking lots shall be landscaped along the property boundaries with shrubbery, trees and other landscape materials. In the LV, MV, VC, LI, and R4 Zones, and that portion of the CC that fronts on Rt. 201, a combination of fencing, landscaping and grading shall be utilized to screen parking areas and minimize the impact of vehicle head lights on adjacent residential uses.
[Amended 5-17-2000 STM, Art. 15; 5-20-2009 STM, Art. 15]
(1) 
No industrial or commercial buildings or uses shall be established in, or abut, a residential district or use, unless a landscaped buffer strip is provided to visually screen the uses. Where no natural vegetation can be maintained or due to varying site conditions the landscaping may consist of fences, walls, hedges or combinations thereof. The buffering shall be sufficient to minimize the impacts of any kind of potential use such as loading and unloading operations, outdoor storage areas, vehicle parking, mineral extraction, waste collection and disposal areas. Where a potential safety hazard to small children would exist, physical screening barriers shall be used to deter entry to such premises. The buffer areas shall be maintained and vegetation replaced to ensure continuous year-round screening.
(2) 
Landscaping must consist of full vegetative ground cover. Rock, bark and other nonliving material may be used only for accent in landscaped areas. All landscaped areas must be maintained in a healthy growing condition.
(3) 
A minimum six-foot wide landscaped area must be installed adjacent to all sides of commercial buildings and structures except in the LV Zone and industrial buildings in the LI Zone. In the LV, VC, BP2 and LI Zones, and that portion of the CC that fronts on Rt. 201, where the front of the building directly abuts a streetscape, a six-foot wide landscaped area is not required. The design of the streetscape shall meet all other applicable standards.
B. 
Additional requirements for the Mixed Use Limited (MUL) and Mixed Use Commercial (MUC) Zones:
(1) 
There shall be a minimum thirty-five-foot setback from the top of the bank of any stream channel or ravine area.
The applicant shall provide for the disposal of all solid and liquid wastes on a timely basis and in an environmentally safe manner. The Planning Board or Zoning Board of Appeals, as appropriate, shall consider the impact of particular industrial or chemical wastes or by-products upon the town's facilities (in terms of volume, flammability or toxicity) and may require the applicant to dispose of such wastes elsewhere, in conformance with all applicable state and federal regulations. The Boards may require the applicant to specify the amount and exact nature of all industrial or chemical wastes to be generated by the proposed operation.
A. 
On-site disposal.
(1) 
When a lot is not served by the public sewerage system, the approval of building permit applications shall be subject to presentation of a completed site evaluation form (HHE-200) which evidences adequate soil conditions for sewage disposal. The septic tank and leaching field system serving a structure shall be entirely located on the same lot as that structure. The only exception to the foregoing requirement shall be private sewage collection and disposal systems serving subdivisions of individual single-family homes, provided that:
(a) 
The subdivision is located within the jurisdiction of the Topsham Sewer District and in an area that is scheduled to be served by the Topsham Sewer District, as documented in its current master plan;
(b) 
The subdivision includes no more than 10 lots;
(c) 
Each home has its own septic tank, and the private system collects and disposes of septic tank effluent;
(d) 
The common leaching facility is located on a separate lot large enough to include a standby disposal area equal in size to the original;
(e) 
The design of the sewage collection and disposal system is prepared by a registered professional engineer and is approved by the Maine Department of Human Services and by the Topsham Sewer District;
(f) 
The leaching facility is located at least 300 feet from any private well;
(g) 
All lots shall have deed covenants noting the financial obligation of the owner to pay his pro rata share of all system maintenance, repair and replacement; and
(h) 
All sewer lines shall be installed within easements outside the limits of roadways in the subdivision.
(2) 
No on-site sewage treatment and disposal system of greater than 2,000 gallon-per-day capacity shall be approved until the applicant has conducted a hydrogeologic analysis which demonstrates to the satisfaction of the Planning Board that:
(a) 
The soils are suitable for the expected volume and characteristics of waste;
(b) 
Adequate land exists on the lot for complete replacement of the leaching facility;
(c) 
The direction of groundwater flow and subsurface conditions are such as not to imperil proposed on-site water supplies; and
(d) 
The quality of groundwater at the property line is maintained within federal drinking water standards. The applicant shall base hydrogeologic analysis on soil borings and monitoring wells sufficient to document existing soil, bedrock and groundwater conditions. As a condition of approval, the applicant shall agree to install sufficient monitoring wells (at least one up-gradient and two down-gradient) and to provide for adequate sampling and analysis therefrom over an appropriate time period to demonstrate that groundwater quality is maintained.
B. 
Off-site disposal. Industrial wastewaters may be discharged to municipal sewers only and in such quantities and/or of such quality as to be compatible with commonly accepted municipal sewage treatment operations. Such wastes may require pretreatment at the industrial site in order to render them amenable to municipal treatment processes. Pretreatment includes, but is not limited to, screening, grinding, sedimentation, pH adjustment, surface skimming, chemical oxidation and reduction and dilution. The disposal of industrial wastewaters by means other than the municipal sewerage system must comply with the laws of the State of Maine concerning water pollution. Wash water or other process water carrying stone dust, stone particles, silt or other mineral matter will not be accepted into the municipal system.
(1) 
Prohibited wastes. No person shall discharge or cause to be discharged any of the following described waters or wastes to any public sanitary sewers or, except as set forth in Subsection B(1)(a) below, to any storm drains or any part thereof:
(a) 
Water from roof downspouts, foundation drains or areaway drains or any other sources of surface runoff or groundwater; nor discharge or cause to be discharged any stormwater, surface water, groundwater, roof runoff, subsurface drainage, uncontaminated cooling water or unpolluted industrial process waters, except into storm drains.

[Amended 5-17-2000 STM, Art. 15; 5-20-2009 STM, Art. 15; 5-17-2017 STM, Art. 13]
A. 
Intent. Recognizing that development activity increases the rate and volume of stormwater runoff by reducing the infiltrative capacity of soils and that stormwater runoff increases the potential of flooding and adds pollution to water resources, and increases erosion and sedimentation, the purpose of this section is to encourage the management of stormwater on the land at the site of development and, to the extent practical, to do so through the use of the natural features of the site. This policy will preserve the natural drainage system, valuable topsoil, water quality, and wildlife habitat during and after construction through infiltration, detention, or retention of water falling on the site. The management of stormwater shall not constitute a threat to public health, safety and welfare and shall not degrade the quality of Topsham's surface water or groundwater below state or Town standards. It shall be the responsibility of the property owner and/or developer to adequately provide for the necessary control of stormwater runoff and erosion.
B. 
Applicable standards for stormwater management. The standards for stormwater management vary depending on the type of project and the amount of disturbed area as follows:
(1) 
Post-construction stormwater management plan. Subdivisions and activities subject to site plan review that involve more than one acre of disturbed area must meet the requirements for a post-construction stormwater management plan.
(2) 
Municipal stormwater management plan. Subdivisions and activities subject to site plan review by the Planning Board that are not subject to the requirements for a post-construction stormwater management plan must meet the requirements for a municipal stormwater management plan.
C. 
Standards for a post-construction stormwater management plan.
(1) 
Design standard.
The applicant shall make adequate provision for the management of the quantity and quality of all stormwater generated by the activity through a post-construction stormwater management plan. This post-construction stormwater management plan shall be designed to meet the appropriate standards and requirements based on the project's scale for a stormwater permit from the Maine Department of Environmental Protection (DEP) under its Chapter 500 Stormwater Management Rules, as may be amended from time to time (DEP Chapter 500 Rules). The Town's approval shall be under its municipal capacity to approve stormwater plans that are exempt from DEP review under the Town's delegated review authority.
In addition, projects located in the watershed of an urban impaired stream must comply with the requirements for chlorides management set forth in Subsection E, Standards for chlorides management.
(2) 
Additional requirements.
(a) 
The applicant may meet the standards above either on-site or off-site, but where off-site facilities are used, the applicant must submit to the Town Planner documentation approved as to legal sufficiency by the Town's legal counsel that the applicant has a sufficient property interest in the property where the off-site facilities are located, by perpetual easement or other appropriate legal instrument, to ensure that the facilities will be able to provide post-construction stormwater management for the project and that the property will not be altered in a way that interferes with the off-site facilities.
(b) 
Where the applicant proposes to retain ownership of the stormwater management facilities shown in its stormwater management plan, the applicant shall submit to the Town Planner documentation, approved as to legal sufficiency by the Town's legal counsel, that the applicant, his/her/its successors, heirs and assigns, shall have the legal obligation to operate, repair, maintain and replace the stormwater management facilities. Applications requiring stormwater management facilities that will not be dedicated to the Town shall enter into a drainage maintenance agreement with the Town in a form acceptable to the Town's legal counsel.
(c) 
Whenever elements of the stormwater management facilities are not within the right-of-way of a public street and the facilities will not be offered to the Town for acceptance as public facilities, the Planning Board may require that perpetual easements be provided to the Town allowing access for maintenance, repair, replacement and improvement of the stormwater management facilities in accordance with the approved drainage maintenance agreement. If an offer of dedication is proposed, the applicant shall be responsible for the maintenance of these stormwater management facilities until such time (if ever) as they are accepted by the Town.
(d) 
In addition to any other applicable requirements of this chapter, any activity which would have required a stormwater management permit from the DEP under 38 M.R.S.A. § 420-D but that is subject to the Town's delegated review authority shall comply with the rules adopted by DEP under 38 M.R.S.A. § 420-D(1), as the same may be amended from time to time, and the applicant shall document such compliance to the Planning Board. Where the standards or other provisions of such stormwater rules conflict with Town ordinances, the stricter (more protective) standard shall apply.
(e) 
At the time of application, the applicant shall notify the Director of Public Works if its stormwater management plan includes any stormwater BMP(s) that will discharge to the Town's stormwater system and shall include in this notification a listing of which stormwater BMP(s) will so discharge.
(f) 
Prior to the issuance of a certificate of occupancy for the project, the applicant must submit an inspection report to the Code Enforcement Officer documenting that the stormwater facilities have been installed and are functioning as designed and approved and are fully operational. This inspection report must be prepared by a qualified third party inspector as defined in Subsection C(3)(e).
(3) 
Requirement for compliance. Any person owning, leasing or having control over stormwater management facilities required by a post-construction stormwater management plan shall demonstrate compliance with that plan as follows:
(a) 
That person shall, at least annually, inspect, clean and maintain the stormwater management facilities, including, but not limited to, any parking areas, catch basins, drainage swales, detention basins and ponds, pipes and related structures, in accordance with all Town and state inspection, cleaning and maintenance requirements of the approved post-construction stormwater management plan.
(b) 
That person shall repair, or cause to be repaired, any deficiencies found during inspection of the stormwater management facilities.
(c) 
That person shall, on or by July 15 of every other year commencing with the second year following occupancy, provide a completed and signed certification to the Director of Public Works in a form provided by that Department, certifying that the person has inspected, cleaned and maintained the stormwater management facilities, describing any deficiencies found during inspection of the stormwater management facilities and certifying that the person has repaired any deficiencies in the stormwater management facilities noted during the annual inspection.
(d) 
The required inspection(s) must be conducted by a qualified third-party inspector employed or engaged by the responsible person if the property would have been subject to a DEP stormwater permit. The third-party inspector shall perform an initial inspection to determine the status of the stormwater management facilities. If the initial inspection identifies any deficiencies with the facilities, the same third-party inspector shall reinspect the facilities after they have been maintained or repaired to determine if they are performing as intended.
(e) 
The qualified third-party inspector must meet both of the following standards:
[1] 
The inspector must not have any ownership or financial interest in the property being inspected nor be an employee or partner of any entity having an ownership or financial interest in the property; and
[2] 
The inspector must be on the list of approved third-party inspectors maintained by the Planning and Development Department. An individual may request to be included on the list by submitting documentation of his/her qualifications to the Planning Director. The Director shall approve third-party inspectors only if they meet the following criteria:
[a] 
Have a college degree in an environmental science or civil engineering, or comparable expertise;
[b] 
Have a practical knowledge of stormwater hydrology and stormwater management techniques, including the maintenance requirements for stormwater management facilities; and
[c] 
Have the ability to determine if stormwater facilities are performing as intended.
(f) 
In order to determine compliance with this section and with the post-construction stormwater management plan, the Director of Public Works or his/her designee may enter upon a property at reasonable hours and after making a good faith effort to contact the owner, occupant or agent to inspect the stormwater management facilities. Entry into a building shall only be after actual notice to the owner, occupant or agent.
(4) 
Submission requirements.
A post-construction stormwater management plan shall conform to the applicable submission requirements of the DEP Chapter 500 Rules. If the project is located within the watershed of an urban impaired stream, the submission must include a chlorides management plan as set forth in Subsection E.
The applicant shall provide the Town with an electronic version of the post-construction stormwater management plan in a format that is compatible with the Town's requirements. Following completion of construction, the applicant shall provide the Department of Planning and Development with an updated version of the plan showing the stormwater management facilities as actually constructed.
(5) 
Relationship to other provisions. Post-construction stormwater management plans are subject to the requirements of Subsection F, Standards for easements or rights-of-way; Subsection G, Modification of the standards and requirements; and Subsection H, Discharge of stormwater.
D. 
Standards for a municipal stormwater management plan.
(1) 
Design standard.
The applicant shall make adequate provision for the management of the quantity and quality of all stormwater generated by the activity through a municipal stormwater management plan. This municipal stormwater management plan shall be designed to meet the basic standard of DEP Chapter 500 Rules and the runoff from the site LID design practices and techniques determined by the Planning Board to be appropriate to the site or other stormwater management provisions. The treatment techniques used may include those set forth in the DEP Stormwater Manual, Volume III-BMPs Technical Design Manual, and/or any other LID practices adopted by the Planning Board. The Planning Board may approve the use of other treatment techniques on a case-by-case basis based upon the recommendation of the Director of the Department of Planning and Development that the proposed treatment techniques are appropriate for the site and will provide at least the same level of treatment as the specified techniques. Provisions must be made in the stormwater management plan for all stormwater treatment techniques to be maintained in perpetuity.
In addition, projects located in the watershed of an urban impaired stream must comply with the requirements for chlorides management set forth in Subsection E, Standards for chlorides management.
(2) 
Additional requirements.
(a) 
The applicant may meet the standards above either on-site or off-site, but where off-site facilities are used, the applicant must submit to the Planning Director documentation approved as to legal sufficiency by the Town's legal counsel that the applicant has a sufficient property interest in the property where the off-site facilities are located, by perpetual easement or other appropriate legal instrument, to ensure that the facilities will be able to provide post-construction stormwater management for the project and that the property will not be altered in a way that interferes with the off-site facilities.
(b) 
Where the applicant proposes to retain ownership of the stormwater management facilities shown in its stormwater management plan, the applicant shall submit to the Planning Director documentation, approved as to legal sufficiency by the Town's legal counsel, that the applicant, his/her/its successors, heirs and assigns, shall have the legal obligation to operate, repair, maintain and replace the stormwater management facilities. Applications requiring stormwater management facilities that will not be dedicated to the Town shall enter into a drainage maintenance agreement with the Town in a form acceptable to the Town's legal counsel.
(c) 
Whenever elements of the stormwater management facilities are not within the right-of-way of a public street and the facilities will not be offered to the Town for acceptance as public facilities, the Planning Board may require that perpetual easements be provided to the Town allowing access for maintenance, repair, replacement and improvement of the stormwater management facilities in accordance with the approved drainage maintenance agreement. If an offer of dedication is proposed, the applicant shall be responsible for the maintenance of these stormwater management facilities until such time (if ever) as they are accepted by the Town.
(d) 
In addition to any other applicable requirements of this chapter, any activity which would require a stormwater management permit from the DEP under 38 M.R.S.A. § 420-D shall comply with the rules adopted by DEP under 38 M.R.S.A. § 420-D(1), as the same may be amended from time to time, and the applicant shall document such compliance to the Planning Board. Where the standards or other provisions of such stormwater rules conflict with Town ordinances, the stricter (more protective) standard shall apply.
(e) 
At the time of application, the applicant shall notify the Director of Public Works if its stormwater management plan includes any stormwater BMP(s) that will discharge to the Town's stormwater system and shall include in this notification a listing of which stormwater BMP(s) will so discharge.
(f) 
If the municipal stormwater management plan includes the use of proprietary water quality treatment devices, the applicant shall provide documentation of how the proprietary devices will be maintained, including what firm will be responsible and frequency of maintenance.
(3) 
Requirement for compliance. Any person owning, leasing or having control over stormwater management facilities required by a municipal stormwater management plan shall be responsible for maintaining all stormwater management facilities and BMPs so they function as designed and approved.
(4) 
Submission requirements.
A general stormwater management plan shall conform to the applicable submission requirements for basic standards submissions of the DEP Chapter 500 Rules. If the project is located within the watershed of an urban impaired stream, the submission must include a chlorides management plan as set forth in Subsection E.
The applicant shall provide the Town with an electronic version of the municipal stormwater management plan in a format that is compatible with the Town's requirements. Following completion of construction, the applicant shall provide the Town with an updated version of the plan showing the stormwater management facilities as actually constructed.
(5) 
Relationship to other provisions. Municipal stormwater management plans are subject to the requirements of Subsection F, Standards for easements or rights-of-way; Subsection G, Modification of the standards and requirements; and Subsection H, Discharge of stormwater.
E. 
Standards for chlorides management. Any project located within the watershed of an urban impaired stream that is subject to site plan review by the Planning Board under Chapter 175 or subdivision review under Chapter 191 must prepare a chlorides management plan (CMP) in accordance with the provisions of this section. This requirement applies to any amendment to a previously approved site plan that requires Planning Board approval and any amendment to a previously approved subdivision plan that increases the number of lots.
(1) 
Purpose. The CMP requirement is intended to minimize the impact of chlorides from snow and ice control activities on the impaired stream by limiting the amount of impervious surface that needs to be treated and by managing snow and ice control facilities and operations.
(2) 
Contents of the chlorides management plan. The CMP must address the following areas:
(a) 
How the project will be designed and constructed to minimize the need for the use of chlorides for snow and ice control. The plan should address how the site layout and design minimizes the amount of impervious surface and how the need for snow and ice control treatments will be reduced. This can include approaches such as limiting the area of access drives, parking, and service areas, providing areas that will be designated for limited or no snow and ice control treatment, and the use of alternative provisions for snow and ice control such as covered or heated walkways that reduce the need for the use of chlorides.
(b) 
If chlorides for ice and snow removal will be stored on-site, how the project will be designed and constructed to manage the stormwater runoff from chloride storage areas. The plan should address how the materials will be stored to prevent chloride contaminated runoff, including the location and design of the storage area, and provisions for stormwater management.
(c) 
How the project will be designed and constructed to manage the stormwater runoff from snow storage areas. The plan must indicate if snow will be stored on-site and if so, designate where this will occur. The plan should address how the snow storage area will be designed to prevent surface drainage from getting into the storage area and how the meltwater will be handled to direct it to the stormwater system and to avoid infiltration into the ground.
(d) 
How the project will be designed and constructed to manage the stormwater runoff from treated areas. The plan must address how stormwater will be handled to direct it to the stormwater system and to avoid infiltration into the ground.
(e) 
How snow and ice control activities will be carried out to minimize the use of chlorides. The plan must include an operations manual that spells out who will be responsible for overseeing snow and ice control activities, requirements for the training of snow and ice control equipment operators, the provision and use of appropriate equipment for the particular site, the calibration of spreaders or other applicators, and guidance for determining the proper materials and application rates based on the site and weather conditions.
(3) 
Review and approval of the chlorides management plan. The Planning Board shall review the CMP as part of the overall project review since the CMP is an integral part of the overall layout and design of the project. In its review of a CMP, the Planning Board may require the applicant to modify the proposed location of the building on the site or the layout and design of the project on the site if necessary to meet the requirements of this section. The Planning Board shall find that all of the following standards are met to approve an application including a CMP:
(a) 
The location, overall layout and design of the project will minimize the amount of impervious surface that will require snow and ice control to the extent reasonable with the planned use of the site.
(b) 
The location and design of any chloride storage areas will minimize the potential for adverse impact on the stream from chlorides to the extent reasonable with the planned use of the site.
(c) 
The location and design of any snow storage areas will minimize the potential for adverse impact on the stream from chlorides to the extent reasonable with the planned use of the site.
(d) 
The overall design of the site and the stormwater management system will minimize the potential for the infiltration of stormwater containing chlorides into the ground.
(e) 
The operations manual will assure that snow and ice control operations, if carried out in accordance with the manual, will minimize the potential for adverse impact on the stream from chlorides to the extent reasonable with the planned use of the site.
F. 
Standards for easements or rights-of-way. Drainage easements or rights-of-way containing components of the stormwater runoff system lying outside of public street right-of-way lines shall conform to the following standards:
(1) 
The minimum width of the easement shall be 30 feet, provided that where a watercourse or retention area is wider than 30 feet, the Planning Board may require a drainage right-of-way of adequate width to conform substantially to the lines of such watercourse or retention area, including additional width to provide for access. The Planning Board may reduce the width of the easement upon the positive recommendation of the Director of Public Works or his/her designee if the narrower easement will allow the stormwater facilities to be maintained or if the unique characteristics of the site make the creation of a wider easement impractical.
(2) 
Where a drainage easement will contain an open channel, stream or drainageway, the easement shall be designed and landscaped to further the objectives of the stormwater management plan. The natural landscape shall be retained to the extent practical as determined by the Planning Board or Code Enforcement Officer, as applicable.
(3) 
Where the easement will contain a closed conduit the facility shall be constructed in accordance with the approved plan.
G. 
Modification of the standards and requirements.
(1) 
The Planning Board or Planning Director where he/she is the reviewing authority may modify or waive any of the submission requirements for a post-construction stormwater management plan or a general stormwater management plan if the Planning Board or Planning Director finds that, due to the unique physical characteristics of the site or the scale of the proposed activity, the information is not required to allow the Planning Board or Planning Director to determine if the applicable stormwater management standards are met.
(2) 
The Planning Board or Planning Director where he/she is the reviewing authority may approve a post-construction stormwater management plan that does not comply with the detailed requirements of Subsection C or a municipal stormwater management plan that does not comply with the detailed requirements of Subsection D if the Planning Board or Planning Director finds that the proposed plan will provide the same or higher level of water quality protection than strict conformance with the applicable standard or that due to the unique physical characteristics of the site and/or the receiving waters, full conformance with the standard is not warranted to assure that the quality of the receiving waters will not be degraded.
H. 
Discharge of stormwater.
(1) 
The volume of stormwater discharged from any parcel must be minimized to the extent practical. When stormwater must be discharged from a parcel, the preferred method is discharge into the natural drainage system. Discharge of stormwater to the Town's stormwater system shall be allowed only when on-site retention and/or discharge to the natural system is not practical or when necessary to minimize the impacts of chlorides on an urban impaired stream.
(2) 
The direct connection of new or expanded stormwater management facilities to a combined sewer is not permitted.
I. 
Aquifer recharge.
(1) 
Stormwater management systems should be designed to facilitate aquifer recharge when it is advantageous to compensate for groundwater withdrawals. Conversely, designs should avoid recharge where groundwater effects might be harmful. Design of permanent storage facilities should consider safety, appearance, recreational use and cost and effectiveness of maintenance operations, in addition to the primary storage function. Natural overland flows and open drainage channel and swale locations should be the preferred alignments for major components of a residential drainage system. The use of enclosed components (such as underground piping) should be minimized where the existing natural systems are able to accommodate storm runoff. Energy dissipaters (to reduce high flow velocities) and other forms of outfall protection shall be employed where enclosed drains discharge onto erodible soils.
J. 
Overall design.
(1) 
Stormwater management systems should be integrated into the overall landscape plan. Stormwater structures such as swales, basins, culverts, rip rap and headwalls shall be located and designed to blend with the natural environment. Native and wetland tolerant plants should be used to soften hard structures and add wildlife value. Stormwater systems should be considered as engineered wetland systems that have visual and ecological value.
K. 
Green roofs.
(1) 
Green roof systems may be utilized as part of a stormwater management system plan if the efficacy of the system can be demonstrated using the Rational or S.C.S. Method.
[Amended 5-21-1997 STM, Art. 39]
All outdoor storage facilities for fuel, chemicals, chemical or industrial wastes and biodegradable raw materials shall be located on impervious pavement, and shall be completely enclosed by an impervious dike which shall be high enough to contain the total volume of liquid kept within the storage area, plus the rain falling into this storage area during a twenty-five-year storm (a twenty-five-year storm is defined as 5.5 inches in a twenty-four-hour period) so that such liquid shall not be able to spill onto or seep into the ground surrounding the paved storage area. Storage for home heating fuel, not exceeding 275 gallons in size, may be exempted from this requirement in situations where neither a high seasonal water table (within 15 inches of the surface) nor rapidly permeable sandy soils are involved.
All uses must connect to the Brunswick-Topsham Water District system when service can be extended to satisfy the daily consumption demands and fire protection needs required for the development or facility. Wherever the development cannot be adequately serviced by the Brunswick-Topsham Water District, evidence of the estimated quantity of groundwater or surface water to be used shall be provided. The quantity of the water to be taken or used shall not substantially lower the groundwater table or surface water levels; cause adverse changes in groundwater flow patterns; or cause ground subsidence.
A. 
The maximum permissible sound pressure level of any continuous regular or frequent source of sound produced by any activity shall be limited by the time period and use district listed below. Sound levels shall be measured at least four feet above ground at the property boundary.

(2) 
Sounds emanating from safety signals, warning devices, emergency pressure relief valves and other emergency activities.
(3) 
Sounds emanating from traffic on public transportation facilities.
No activity shall be permitted in any area where the soil is rated severe or very severe for the proposed activity, according to the Sagadahoc County Soil Suitability Guide of the United States Soil Conservation Service, unless satisfactory evidence is presented to the Code Enforcement Officer, within the application for a permit, that construction methods will overcome any pertinent soil inadequacies if modification of the soil is made meeting the requirements of the United States Soil Conservation Service for upgrading the area to a rating of fair or higher, building on soils initially rated poor or lower may be permitted.
All materials stored outdoors shall be stored in such a manner as to prevent the breeding and harboring of insects, rats or other vermin. This shall be accomplished by enclosures in containers, raising materials above ground, separation of material, prevention of stagnant water, extermination procedures or other means. Exposed storage areas for machinery, raw materials or furnished products or mineral excavation and processing operations shall have setbacks and screening (such as a stockade fence or dense evergreen hedge) sufficient to provide a visual buffer to minimize their adverse impact on abutting land uses. Where a potential safety hazard to small children would likely arise, physical screening to prevent access shall be provided.
No use shall for any period of time discharge across the boundaries of the lot wherein it is located toxic and noxious matter in concentrations in excess of one-fourth (1/4) of the maximum allowable concentrations set forth in the Industrial Hygiene Standards Maximum Allowable Concentrations, of the Air Pollution Abatement Manual, by Manufacturing Chemists' Association, Inc., Washington D.C., as subsequently amended or revised, which is hereby incorporated in and made a part of this section by reference.
Vibration inherently and recurrently generated shall be imperceptible without instruments at lot boundaries.
[Added 5-18-2016 STM, Art. 14]
All activities shall be carried out to minimize the impact on vernal pools except for projects involving vernal pool mitigation in accordance with § 225-20.2, Vernal Pools Overlay District. All development activities on a site with one or more vernal pools shall be located and designed to conserve the pools plus the necessary terrestrial amphibian post-breeding habitat adjacent to each pool to the maximum extent reasonable consistent with the proposed use of the property unless vernal pool mitigation is proposed. If the encroachment on a vernal pool or its adjacent habitat falls under state or federal regulation, no activity shall occur until the property owner has received the appropriate permit from the state and/or federal agency or has met the requirements of the (VPO District) with respect to vernal pool mitigation.
