NOTES:
1.
Protected water resources include normal high-water line of freshwater bodies, the maximum spring high tide level (MHHW) of tidal waters, and the upland edge of a wetland
2.
This provision shall not apply to structures such as transmission towers, windmills, antennas, and similar structures having no floor area. Cupolas, domes, widow's walks or similar features shall be exempt.
(2) 
If more than one residential dwelling unit, principal governmental, institutional, commercial, or industrial structure or use, or combination thereof, is constructed or established on a single parcel, all dimensional requirements shall be met for each additional dwelling unit, principal structure, or use.
(3) 
Minimum lot width. Within 100 feet, horizontal distance, of the normal high-water line of a water body or upland edge of a wetland, the minimum width of any portion of any lot shall be equal to or greater than the required shore frontage for the proposed use.
(4) 
The water body or wetland setback provision shall neither apply to structures which require direct access to the water as an operational necessity, such as piers, docks and retaining walls, nor to other functionally water-dependent uses.
(5) 
The lowest floor elevation or openings of all buildings and structures including basements shall be elevated at least one foot above the elevation of the 100-year flood, the flood of record, or, in the absence of these, the flood as defined by soil types identified as recent floodplain soils. Accessory structures may be placed in accordance with City Code Chapter 106, Floodplain Management, and need not meet the elevation requirements of this subsection.
(6) 
Lot coverage.
(a) 
Nonvegetated surfaces shall not exceed a total of 20% of the portion of the lot located within the Shoreland Zoning Overlay District, except in the SI, CE, and Coastal Development Overlay Districts. This limitation does not apply to public boat launching facilities, regardless of the district in which the facility is located.
(b) 
In the SI and CE Districts located adjacent to coastal wetlands, or rivers that do not flow to great ponds, nonvegetated surfaces shall not exceed a total of 70% of the portion of the lot located within the Shoreland Overlay District. The total nonvegetated surface shall not exceed 40% of a lot or a portion thereof located within the Coastal Development Overlay District.
(c) 
For the purposes of calculating lot coverage, nonvegetated surfaces include, but are not limited to, the following: structures, driveways, parking areas, and other areas from which vegetation has been removed. Naturally occurring ledge and rock outcroppings are not counted as nonvegetated surfaces when calculating lot coverage for lots of record on March 24, 1990, and in continuous existence since that date.
(d) 
For the purposes of this article, a building is a structure designed for habitation, shelter, storage, or as a gathering place that has a roof. For the purposes of this rule, the foundation is part of the building. A porch with a roof, attached to the exterior walls of a building, is considered part of the building.
B. 
Notwithstanding the requirements stated above, stairways or similar structures may be allowed, with a permit from the CEO, to provide shoreline access in areas of steep slopes or unstable soils, provided that the structure is limited to a maximum of four feet in width; that the structure does not extend below or over the normal high-water line of a water body or upland edge of a wetland, unless permitted by the Department of Environmental Protection pursuant to the Natural Resources Protection Act, 38 M.R.S.A § 480-C; and that the applicant demonstrates that no reasonable access alternative exists on the property.
C. 
For principal structures, water and wetland setback measurements shall be taken from the top of a coastal bluff that has been identified on coastal bluff maps as being "highly unstable" or "unstable" by the Maine Geological Survey pursuant to its "Classification of Coastal Bluffs" and published on the most-recent Coastal Bluff Map. If applicants and the permitting official(s) are in disagreement as to the specific location of a "highly unstable" or "unstable" bluff, or where the top of the bluff is located, applicants may, at their expense, employ a Maine registered professional engineer, a Maine certified soil scientist, a Maine state geologist, or other qualified individual to make a determination. If agreement is still not reached, the applicant may appeal the matter to the Board of Appeals.
D. 
On a nonconforming lot of record on which only a residential structure exists, and on which it is not possible to place an accessory structure meeting the required setbacks, whether from water body, tributary stream, or wetlands, the CEO may issue a permit to place a single accessory structure not to exceed 80 square feet in area nor eight feet in height, with no utilities, for the storage of yard tools and similar equipment. The accessory structure shall be located as far from the shoreline or tributary stream or wetland as practical and shall meet all other applicable standards, including lot coverage and vegetation clearing standards. The accessory structure shall not be located closer to the shoreline, tributary stream, or wetland than the principal structure.
E. 
Retaining walls that are not necessary for erosion control shall meet the structure setback requirement, except for low retaining walls and associated fill, provided each of the following conditions are met:
(1) 
The site has been previously altered and an effective vegetated buffer does not exist;
(2) 
The wall is at least 25 feet, horizontal distance, from the normal high-water line of a water body, tributary stream, or upland edge of a wetland;
(3) 
The site where the retaining wall will be constructed is legally existing lawn or is a site eroding from lack of naturally occurring vegetation, and which cannot be stabilized with vegetative plantings;
(4) 
The total height of the wall, in the aggregate, is not more than 24 inches;
(5) 
The location is outside the 100-year floodplain on rivers, streams, coastal wetlands, and tributary streams, as designated on the Federal Emergency Management Agency's (FEMA) Flood Insurance Rate Maps or Flood Hazard Boundary Maps;
(6) 
The area behind the wall is revegetated with grass, shrubs, trees, or a combination thereof, and no further structural development will occur within the setback area, including patios and decks; and
(7) 
A vegetated buffer area is established within 25 feet, horizontal distance, of the normal high-water line of a water body, tributary stream, or upland edge of a wetland when a natural buffer area does not exist. The buffer area must meet the following characteristics:
(a) 
The buffer must include shrubs and other woody and herbaceous vegetation. Where natural ground cover is lacking, leaf or bark mulch or an equivalent alternative acceptable to the CEO shall be utilized.
(b) 
Plantings, native species only, shall be installed to retard erosion and provide for effective infiltration of stormwater runoff.
(c) 
A minimum buffer width of 15 feet, horizontal distance, is required, measured perpendicular to the normal high-water line or upland edge of a wetland.
(d) 
A footpath no greater than four feet in width may traverse the buffer at a right angle.
(e) 
All permits required by the Maine Department of Environmental Protection and/or other regional, state, or federal agencies shall have been issued prior to the start of work.
A. 
Performance standards.
(1) 
All applications for temporary piers, docks, wharves and other marine structures shall be reviewed by the CEO, and all applications for permanent piers, docks, wharves and other marine structures shall be reviewed by the Planning Board. All such applications shall be reviewed for conformance with the following standards listed below.
(2) 
If the reviewing authority is unable to reach a decision using the criteria below due to either inconclusive or conflicting information, the reviewing authority will require the applicant to submit an environmental impact analysis assessing the proposal's impact on natural areas, including impacts of the proposed structure in conjunction with other adjacent or abutting structures.
(3) 
The reviewing authority may also require that the proposal be modified to ensure conformance with the standards set forth below. Mitigation measures may include, but are not limited to, changes in the design and construction of the marine structure, or changes in magnitude, duration, and location of activities carried out at the marine structure.
(4) 
An application shall be approved by the reviewing authority if there is a finding that:
(a) 
No more than one pier, dock, wharf or similar structure extending or located below the normal high-water line of a water body or within a wetland is allowed on a single lot; except that when a single lot contains at least twice the minimum shore frontage as specified in this article, a second structure may be allowed and may remain as long as the lot is not further divided.
(b) 
Access from the shore shall be developed on soils appropriate for such use, as determined through consultation with the local Soil and Water Conservation District office. Whenever possible, access from the shore to the marine structure shall be placed on bedrock. Measures shall be taken to minimize soil erosion both during and after construction.
(c) 
The proposed location of the marine structure shall not unreasonably interfere with access to existing marine structures or points of public access, nor shall it unreasonably interfere with existing developed or natural beach areas.
(d) 
The marine structure shall be designed, sited, and constructed to mitigate unreasonable adverse impacts on significant wildlife habitats or unique natural areas, including, but not limited to fin fish and shellfish fisheries, salt marshes, eel grass beds, shorebird feeding and nesting habitats, critical fish spawning and nursery areas, etc.
(e) 
Unreasonable interference with the natural flow of any surface or subsurface waters or impedance of the flow of the current of any river or channel shall be minimized during construction and subsequent use of the marine structure.
(f) 
The marine structure shall be designed, sited, and constructed so as not to encroach upon federally designated navigation channels or mooring areas or otherwise obstruct by any means whatsoever the free use of piers, docks, and other common landing places.
(g) 
The marine structure shall be no larger than necessary to accomplish the purposes for which it is designed, notwithstanding the dimensional limits listed below (Table 8-3). Its size and construction shall not change the intensity of the adjoining land use, and by no means shall it exceed a total distance of more than 1/3 the width of the water body, when proposed for coastal or inland waterways. The applicant may request a variance from the dimensional requirements due to the additional requirement of handicap access or unusual wind or wave conditions.

[4] 
The construction of the deck complies with all other applicable standards, except the shoreline setback requirements in § 230-803.
[5] 
The construction of the deck complies with SRCC regulations and all state and federal laws. New permanent structures, and expansions thereof, projecting into or over water bodies shall require a permit from the Department of Environmental Protection pursuant to the Natural Resources Protection Act, 38 M.R.S.A § 480-C. Permits may also be required from the Army Corps of Engineers if located in navigable waters.
Campgrounds shall conform to the minimum requirements imposed under state licensing procedures, Article VII of this chapter, and the following:
A. 
Campgrounds shall provide a minimum of 5,000 square feet of land, not including roads and driveways, for each site. Land supporting wetland vegetation and land below the normal high-water line of a water body shall not be included in calculating land area per site.
B. 
The areas intended for placement of a recreational vehicle, tent or shelter, and utility and service buildings shall be set back a minimum of 100 feet, horizontal distance, from the normal high-water line of a great pond classified GPA or a river flowing to a great pond classified GPA, and 75 feet, horizontal distance, from the normal high-water line of other water bodies, tributary streams, or the upland edge of a wetland.
A. 
Parking areas shall meet the shoreline and tributary stream setback requirements for structures for the district in which such areas are located, except that in the CE District, parking areas shall be set back at least 25 feet from the normal high-water line or the upland edge of a wetland. The setback requirement for parking areas serving public boat launching facilities in other districts shall be no less than 50 feet from the normal high-water line or upland edge of a wetland if the Planning Board finds that no other reasonable alternative exists.
B. 
Parking areas shall be designed to prevent stormwater runoff from flowing directly into a water body and, to the greatest extent practicable, to retain all runoff on site.
C. 
All parking spaces shall be nine feet wide and 18 feet long, except that parking spaces for a vehicle and boat trailer shall be 40 feet long. See Article X herein for additional parking standards.
A. 
The following standards shall apply to the construction of roads and/or driveways and drainage systems, culverts and other related features:
(1) 
Setback.
(a) 
Roads and driveways shall be set back at least 75 feet, horizontal distance, from the normal high-water line of water bodies, tributary streams, or the upland edge of a wetland, unless no reasonable alternative exists as determined by the Planning Board. If no other reasonable alternative exists, the road and/or driveway setback requirement shall be no less than 50 feet, horizontal distance, upon clear showing by the applicant that appropriate techniques will be used to prevent sedimentation of the water body. Such techniques may include, but are not limited to, the installation of settling basins, and/or the effective use of additional ditch relief culverts and turnouts placed so as to avoid sedimentation of the water body, tributary stream, or wetland.
(b) 
On slopes of greater than 20%, the road or driveway setback shall be increased by 10 feet, horizontal distance, for each 5% increase in slope above 20%.
(c) 
This subsection shall neither apply to approaches to water crossings nor to roads or driveways that provide access to permitted structures, and facilities located nearer to the shoreline due to an operational necessity.
(2) 
Existing public roads may be expanded within the legal road right-of-way regardless of its setback from a water body, tributary stream or wetland.
(3) 
New roads and driveways are prohibited in the Resource Protection Overlay District except to provide access to permitted uses within the district, or as approved by the Planning Board upon a finding that no reasonable alternative route or location is available outside the district, in which case the road and/or driveway shall be set back as far as practicable from the normal high-water line of a water body, tributary stream, or upland edge of a wetland.
(4) 
Road and driveway banks shall be no steeper than a slope of two horizontal to one vertical and shall be graded and stabilized in accordance with the provisions for erosion and sedimentation control detailed in § 230-814.
(5) 
Road and driveway grades shall be no greater than 10% except for short segments of less than 200 feet.
(6) 
In order to prevent road and driveway surface drainage from directly entering water bodies, tributary streams, or wetlands, roads and driveways shall be designed, constructed, and maintained to empty onto an unscarified buffer strip at least 50 feet plus two times the average slope, in width between the outflow point of the ditch or culvert and the normal high-water line of a water body, tributary stream, or upland edge of a wetland. Surface drainage which is directed to an unscarified buffer strip shall be diffused or spread out to promote infiltration of the runoff and to minimize channelized flow of the drainage through the buffer strip.
(7) 
Ditch relief (cross drainage) culverts, drainage dips and water turnouts shall be installed in a manner effective in directing drainage onto unscarified buffer strips before the flow gains sufficient volume or head to erode the road, driveway, or ditch. To accomplish this, the following shall apply:
(a) 
Ditch relief culverts, drainage dips, and associated water turnouts shall be spaced along the road or driveway at intervals no greater than indicated in Table 8-4:

(b) 
Drainage dips may be used in place of ditch relief culverts only where the grade is 10% or less.
(c) 
On sections having slopes greater than 10%, ditch relief culverts shall be placed at approximately a 30° angle down slope from a line perpendicular to the center line of the road or driveway.
(d) 
Ditch relief culverts shall be sufficiently sized and properly installed in order to allow for effective functioning, and their inlet and outlet ends shall be established with appropriate materials.
(e) 
Ditches, culverts, bridges, dips, water turnouts and other stormwater runoff control installations associated with roads and driveways shall be maintained on a regular basis to assure effective functioning.
A. 
Mineral exploration to determine the nature or extent of mineral resources shall be accomplished by hand sampling, test boring, or other methods which create minimal disturbance of less than 100 square feet of ground surface. A permit from the CEO shall be required for mineral exploration which exceeds the above limitation. All excavations, including test pits and holes, shall be immediately capped, filled or secured by other equally effective measures to restore disturbed areas and to protect the public health and safety.
B. 
Mineral extraction may be permitted under the following conditions:
(1) 
A reclamation plan shall be filed with and approved by the Planning Board before a permit is granted. Such plan shall describe in detail procedures to be undertaken to fulfill the requirements of Subsection B(4) below.
(2) 
No part of any extraction operation, including drainage and runoff control features, shall be permitted within 75 feet, horizontal distance, of the normal high-water line of any water body, tributary stream, or the upland edge of a wetland. Extraction operations shall not be permitted within 50 feet, horizontal distance, of any property line without written permission of the owner of such adjacent property.
(3) 
Gravel pits within the shoreland zone shall be set back as far as practicable from the normal high-water line and no less than 75 feet and screened from the river by existing or planted landscaping vegetation.
(4) 
Within 12 months following the completion of extraction operations at any extraction site, which operations shall be deemed complete when less than 100 cubic yards of materials are removed in any consecutive twelve-month period, ground levels and grades shall be established in accordance with the following:
(a) 
All debris, stumps, and similar material shall be removed for disposal in an approved location or shall be buried on site. Only materials generated on site may be buried or covered on site.
(b) 
The final graded slope shall be 2:1 slope or flatter.
(c) 
Topsoil or loam shall be retained to cover all disturbed land areas, which shall be reseeded and stabilized with vegetation native to the area. Additional topsoil or loam shall be obtained from off-site sources if necessary to complete the stabilization project.
(d) 
In keeping with the purposes of this chapter, the Planning Board may impose such conditions as are necessary to minimize the adverse impacts associated with mineral extraction operations on surrounding uses and resources.
A. 
All spreading of manure shall be accomplished in conformance with the Manure Utilization Guidelines published by the former Maine Department of Agriculture on November 1, 2001, and the Nutrient Management Law (7 M.R.S.A § 4201-4214).
B. 
Manure shall not be stored or stockpiled within 300 feet, horizontal distance, of a water body, tributary stream, or wetland. All manure storage areas within the Shoreland Zoning Overlay Districts must be constructed or modified such that the facility produces no discharge of effluent or contaminated stormwater.
C. 
Agricultural activities involving tillage of soil greater than 40,000 square feet in surface area within the Shoreland Zoning Overlay Districts shall require a conservation plan to be filed with the Planning Board. Nonconformance with the provisions of said plan shall be considered a violation of this chapter.
D. 
There shall be no new tilling of soil within 75 feet, horizontal distance, from water bodies nor within 25 feet, horizontal distance, of tributary streams and wetlands. Operations in existence on the effective date of this chapter and not in conformance with this provision may be maintained, provided that such tilling is conducted in accordance with a soil and water conservation plan.
E. 
Newly established livestock grazing areas shall not be permitted within 75 feet, horizontal distance, of water bodies nor within 25 feet, horizontal distance, of tributary streams and wetlands. Livestock grazing associated with ongoing farm activities, and which is not in conformance with the above setback provisions, may continue, provided that such grazing is conducted in accordance with a conservation plan that has been filed with the Planning Board.
A. 
Within the RP Overlay District, cutting or removal of vegetation shall be limited to that which is necessary for uses expressly authorized in that district and shall be demonstrated on a lot clearing plan presented to the CEO or Planning Board as appropriate.
B. 
Buffer strip.
(1) 
In areas that are not in a RP Overlay District and within 75 feet, horizontal distance, from any water body, tributary stream, or the upland edge of a wetland, a buffer strip of vegetation shall be preserved as follows:
(a) 
There shall be no cleared opening greater than 250 square feet in the forest canopy (or other existing woody vegetation if a forested canopy is not present), as measured from the outer limits of the tree or shrub crown. However, a single footpath not to exceed six feet in width, as measured between tree trunks and/or shrub stems is allowed for accessing the shoreline, provided that a cleared line of sight to the water through the buffer strip is not created.
(b) 
Selective cutting of trees within the buffer strip is allowed, provided that a well-distributed stand of trees and other natural vegetation is maintained. For the purposes of this section, a "well-distributed stand of trees" adjacent to water bodies, tributary streams, and wetlands is defined as maintaining a minimum rating score of 16 or more per twenty-five-foot by fifty-foot rectangular area (1,250 square feet) as determined by the following rating system (Table 8-5).

STORM-DAMAGED TREE
A tree that has been uprooted, blown down, is lying on the ground, or that remains standing and is damaged beyond the point of recovery as the result of a storm event.
STREAM
A free-flowing body of water from the outlet of a great pond or the confluence of two perennial streams as depicted on the most recent, highest resolution version of the national hydrography dataset available from the United States Geological Survey on the website of the United States Geological Survey or the national map to the point where the stream becomes a river or where the stream meets the shoreland zone of another water body or wetland. When a stream meets the shoreland zone of a water body or wetland and a channel forms downstream of the water body or wetland as an outlet, that channel is also a stream.
STRUCTURE
In the shoreland zone, "structure" means anything temporarily or permanently located, built, constructed or erected for the support, shelter or enclosure of persons, animals, goods or property of any kind or anything constructed or erected on or in the ground. The term includes structures temporarily or permanently located, such as decks, patios, and satellite dishes. Structure does not include fences; poles and wiring and other aerial equipment normally associated with service drops, including guy wires and guy anchors; subsurface wastewater disposal systems as defined in Title 30-A, Section 4201, Subsection 5; geothermal heat exchange wells as defined in Title 32, Section 4700-E, Subsection 3-C; or wells or water wells as defined in Title 32, Section 4700-E, Subsection 8.
SUBSTANTIAL START
Completion of 30% of a permitted structure or use measured as a percentage of estimated total cost.
SUBSURFACE SEWAGE DISPOSAL SYSTEM
Any system designed to dispose of waste or wastewater on or beneath the surface of the earth; includes, but is not limited to: septic tanks; disposal fields; grandfathered cesspools; holding tanks; pretreatment filter, piping, or any other fixture, mechanism, or apparatus used for those purposes; does not include any discharge system licensed under 38 M.R.S.A § 414, any surface wastewater disposal system, or any municipal or quasi-municipal sewer or wastewater treatment system.
SUSTAINED SLOPE
A change in elevation where the referenced percent grade is substantially maintained or exceeded throughout the measured area.
TEMPORARY STRUCTURE
A structure that is placed on or in the water or shore for a period no greater than seven months in any period of 12 consecutive months. These structures include, but are not limited to, docks, floats, or ramps.
TIDAL WATERS
All waters affected by tidal action during the highest annual tide.
TIMBER HARVESTING
The cutting and removal of timber for the primary purpose of selling or processing forest products. "Timber harvesting" does not include the cutting or removal of vegetation within the shoreland zone when associated with any other land use activities. The cutting or removal of trees in the shoreland zone on a lot that has less than two acres within the shoreland zone shall not be considered timber harvesting. Such cutting or removal of trees shall be regulated pursuant to § 230-810, Clearing or removal of vegetation for activities other than timber harvesting.
TIMBER HARVESTING AND RELATED ACTIVITIES
Timber harvesting, the construction and maintenance of roads used primarily for timber harvesting and other activities conducted to facilitate timber harvesting.
TREE
A woody perennial plant with a well-defined trunk(s) at least two inches in diameter at 4.5 feet above the ground, with a more or less definite crown, and reaching a height of at least 10 feet at maturity.
TRIBUTARY STREAM
A channel between defined banks created by the action of surface water, which is characterized by the lack of terrestrial vegetation or by the presence of a bed, devoid of topsoil, containing waterborne deposits or exposed soil, parent material or bedrock; and which is connected hydrologically with other water bodies. "Tributary stream" does not include rills or gullies forming because of accelerated erosion in disturbed soils where the natural vegetation cover has been removed by human activity. This definition does not include the term "stream" as defined elsewhere in this chapter, and only applies to that portion of the tributary stream located within the shoreland zone of the receiving water body or wetland. Water setback requirements apply to tributary streams within the shoreland zone. This term is used solely in the shoreland zone.
UPLAND EDGE OF A WETLAND
The boundary between upland and wetland. For purposes of a coastal wetland, this boundary is the line formed by the landward limits of the salt tolerant vegetation and/or the highest annual tide level, including all areas affected by tidal action. For purposes of a freshwater wetland, the upland edge is formed where the soils are not saturated for a duration sufficient to support wetland vegetation; or where the soils support the growth of wetland vegetation, but such vegetation is dominated by woody stems that are six meters (approximately 20 feet) tall or taller.
VEGETATION
All live trees, shrubs, and other plants including without limitation, trees both over and under four inches in diameter, measured at 4 1/2 feet above ground level.
VELOCITY ZONE

Such projects include but may not be limited to roads, fords, bridges, culverts, water lines, sewer lines, and cables as well as maintenance work on these crossings. This definition includes crossings for timber harvesting equipment and related activities.
WETLAND
A freshwater or coastal wetland.
WINDFIRM
The ability of a forest stand to withstand strong winds and resist windthrow, wind rocking, and major breakage.
