A. 
In a Resource Protection District abutting a great pond, there shall be no cutting of vegetation within the strip of land extending 100 feet, horizontal distance, and inland from the normal high-water line, except to remove safety hazards. Elsewhere in any Resource Protection District, the cutting or removal of vegetation shall be limited to that which is necessary for uses expressly authorized in that District.
B. 
Except in areas as described in § 110-24A above, and except to allow for the development of permitted uses, within a strip of land extending 100 feet, horizontal distance, inland from the normal high-water line of a great pond classified in the Great Ponds Act or a river flowing to a great pond classified in the Great Ponds Act, and 100 feet, horizontal distance, from any other water body, tributary stream, or the upland edge of a wetland, a buffer strip of vegetation shall be preserved as follows:
(1) 
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 footpath not to exceed six feet in width as measured between tree trunks and/or shrub stems is allowed, provided that a cleared line of sight to the water through the buffer strip is not created.
(2) 
Selective cutting of trees within the buffer strip is allowed, provided that a well-distributed stand of trees and other natural vegetation is maintained.
(a) 
For the purposes of this section, a "well-distributed stand of trees" adjacent to a great pond classified in the Great Ponds Act or a river or stream flowing to a great pond classified in the Great Ponds Act shall be defined as maintaining a rating score of 24 or more in each twenty-five-foot-by-fifty-foot rectangular (1,250 square feet) area as determined by the following rating system.
Diameter of Tree at 4 1/2 feet
above ground level
(inches)
Points
2 to less than 4
1
4 to less than 8
2
8 to less than 12
4
Greater than 12

(b) 
Adjacent to areas zoned as shoreland and slope, a well distributed stand of trees is defined as maintaining a minimum rating score of eight per twenty-five-foot-by-fifty-foot plot area.
(c) 
Adjacent to other water bodies, tributary streams, and wetlands, a "well-distributed stand of trees" is defined as maintaining a minimum rating score of 16 per twenty-five-foot-by-fifty-foot rectangular area.
(d) 
The following shall govern in applying this point system:
[1] 
The twenty-five-foot-by-fifty-foot rectangular plots must be established where the landowner or lessee proposes clearing within the required buffer;
[2] 
Each successive plot must be adjacent to, but not overlap, a previous plot;
[3] 
Any plot not containing the required points must have no vegetation removed except as otherwise allowed by this chapter;
[4] 
Any plot containing the required points may have vegetation removed down to the minimum points required or as otherwise allowed by this chapter;
[5] 
Where conditions permit, no more than 50% of the points on any twenty-five-foot-by-fifty-foot rectangular area may consist of trees greater than 12 inches in diameter.
(3) 
For the purposes of this section, "other natural vegetation" is defined as retaining existing vegetation under three feet in height and other ground cover and retaining at least five saplings less than two inches in diameter at 4 1/2 feet above ground level for each twenty-five-foot-by-fifty-foot rectangle area. If five saplings do not exist, no woody stems less than two inches in diameter can be removed until five saplings have been recruited into the plot. Notwithstanding the above provisions, no more than 40% of the total volume of trees four inches or more in diameter, measured at 4 1/2 feet above ground level, may be removed in any ten-year period.
(a) 
In order to protect water quality and wildlife habitat, existing vegetation under three feet in height and other ground cover, including leaf litter and the forest duff layer, shall not be cut, covered, or removed, except to provide for a footpath or other permitted uses as described in § 110-24A and B.
(b) 
Pruning of tree branches on the bottom 1/3 of the tree is allowed.
(c) 
In order to maintain a buffer strip of vegetation, when the removal of storm-damaged, diseased, unsafe, or dead trees results in the creation of cleared openings, these openings shall be replanted with native tree species unless existing new tree growth is present.
(d) 
Section 110-24B does not apply to those portions of public recreational facilities adjacent to public swimming areas as long as cleared areas are limited to the minimum area necessary.
C. 
At distances greater than 100 feet, horizontal distance, from a great pond classified in the Great Ponds Act or a river flowing to a great pond classified in the Great Ponds Act, and 100 feet, horizontal distance, from the normal high-water line of any other water body, tributary stream, or the upland edge of a wetland, there shall be allowed on any lot, in any ten-year period, selective cutting of not more than 40% of the volume of trees four inches or more in diameter, measured 4 1/2 feet above ground level. Tree removal in conjunction with the development of permitted uses shall be included in the 40% calculation. For the purposes of these standards volume may be considered to be equivalent to basal area. In no event shall cleared openings for any purpose, including, but not limited to, principal and accessory structures, driveways, lawns and sewage disposal areas, exceed, in the aggregate, 25% of the lot area within the Shoreland Zone or 10,000 square feet, whichever is greater, including land previously cleared. This provision shall not apply to the applicable business districts.
D. 
Legally existing nonconforming cleared openings may be maintained, but shall not be enlarged, except as allowed by this chapter.

C. 
Erosion and sedimentation control measures shall apply to all aspects of the proposed project involving land disturbance, and shall be in operation during all stages of the activity. The amount of exposed soil at every phase of construction shall be minimized to reduce the potential for erosion.
D. 
Any exposed ground area shall be temporarily or permanently stabilized within one week from the time it was last actively worked, by use of riprap, sod, seed, and mulch, or other effective measures. In all cases, permanent stabilization shall occur within nine months of the initial date of exposure. In addition:
(1) 
Where mulch is used, it shall be applied at a rate of at least one bale per 500 square feet and shall be maintained until a catch of vegetation is established.
(2) 
Anchoring the mulch with netting, peg and twine or other suitable method may be required to maintain the mulch cover.
(3) 
Additional measures shall be taken where necessary in order to avoid siltation into the water. Such measures may include the use of staked hay bales and/or silt fences.

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.
(2) 
The final graded slope shall be 2 1/2 to one slope or flatter.
(3) 
Top soil 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.
E. 
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.
Piers, docks, wharves, breakwaters, causeways, marinas, bridges, structures and uses extending over or beyond the normal high-water line of a water body or within a wetland. In addition to federal or state permits which may be required for such structures and uses, they shall conform to the following:
A. 
Access from shore shall be developed on soils appropriate for such use and constructed so as to control erosion.
B. 
The location shall not interfere with existing developed or natural beach areas.
C. 
The facility shall be no larger in dimension than necessary to carry on the activity and be consistent with existing conditions, use and character of the area.
D. 
The facility shall be located so as to minimize adverse effects on fisheries.
E. 
No new structure shall be built on, over, or abutting a pier, wharf, dock or other structure extending beyond the normal high water line of a water body or within a wetland unless the structure requires direct access to the water as an operational necessity.
F. 
No existing structures built on, over or abutting a pier, dock wharf, or other structure extending beyond the normal high water line of a water body or within a wetland shall be converted to residential dwelling units in any district.
G. 
Except in the applicable business districts, structures built on, over, or abutting a pier, wharf, dock, or other structure extending beyond the normal high-water line of a water body or within a wetland shall not exceed 20 feet in height above the pier, wharf, dock or other structure.
H. 
Structures built on, over or abutting a pier, wharf, dock or other structure extending beyond the normal high-water line of a water body or within a wetland shall not exceed 20 feet in height above the pier, wharf, dock or other structure.
The following standards shall apply to the construction of roads and/or driveways and drainage systems, culverts and other related features.
A. 
Roads and driveways shall be set back at least 100 feet, horizontal distance, from the normal high-water line of a great pond classified in the Great Ponds Act or a river that flows to a great pond classified in the Great Ponds Act, and 100 feet, horizontal distance from the normal high-water line of other 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, tributary stream, or wetland. 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. On slopes of greater than 20% the road and/or driveway setback shall be increased by 10 feet, horizontal distance, for each five percent increase in slope above 20%. Section 110-28A does not apply to approaches to water crossings or to roads or driveways that provide access to permitted structures and facilities located nearer to the shoreline or tributary stream due to an operational necessity, excluding temporary docks for recreational uses. Roads and driveways providing access to permitted structures within the setback area shall comply fully with the requirements of this section except for that portion of the road or driveway necessary for direct access to the structure.
B. 
New roads and driveways are prohibited in a Resource Protection District except that the Planning Board may grant a permit to construct a road or driveway to provide access to permitted uses within the district. A road or driveway may also be approved by the Planning Board in a Resource Protection District, upon a finding that no reasonable alternative route or location is available outside the district. When a road or driveway is permitted in a Resource Protection District, 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.
C. 
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 contained in § 110-25.
D. 
Road and driveway grades shall be no greater than 10% except for segments of less than 200 feet.
E. 
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.
F. 
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:
(1) 
Ditch relief culverts, drainage dips and associated water turnouts shall be spaced along the road or driveway at intervals no greater than indicated in the following table:
Grade
(percent)
Spacing
(feet)
0 to 2
250
3 to 5
200 to 135
6 to 10
100 to 80
11 to 15
80 to 60
16 to 20
60 to 45
21 +
40
(2) 
Drainage dips may be used in place of ditch relief culverts only where the grade is 10% or less.
(3) 
On sections having slopes greater than 10%, ditch relief culverts shall be placed at approximately a thirty-degree angle downslope from a line perpendicular to the centerline of the road or driveway.
(4) 
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 stabilized with appropriate materials.
G. 
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 ensure effective functioning.
All subsurface sewage disposal systems shall be installed in conformance with the State of Maine Subsurface Wastewater Disposal Rules,[1] and the following:
A. 
Clearing or removal of woody vegetation necessary to site a new system and any associated fill extensions shall not extend closer than 100 feet, horizontal distance, from the normal high-water line of a water body or the upland edge of a wetland and;
B. 
A holding tank is not allowed for a first-time residential use in the Shoreland Zone.
[1]

The total height of the wall, in the aggregate, is no more than 24 inches;
(e) 
Retaining walls are located outside of the one-hundred-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, or the flood of record, or in the absence of these, by soil types identified as recent floodplain soils;
(f) 
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
(g) 
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:
[1] 
The buffer must include shrubs and other woody and herbaceous vegetation. Where natural ground cover is lacking, the area must be supplemented with leaf or bark mulch;
[2] 
Vegetation plantings must be in quantities sufficient to retard erosion and provide for effective infiltration of stormwater runoff;
[3] 
Only native species may be used to establish the buffer area;
[4]

(7) 
Notwithstanding the requirements stated above, stairways or similar structures may be allowed with a permit from the Code Enforcement Officer 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.
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 applicable Residential and Business Districts parking areas shall be set back at least 25 feet, horizontal distance, from the shoreline. The setback requirement for parking areas serving public boat launching facilities in districts other than the applicable Business District shall be no less than 50 feet, horizontal distance, from the shoreline or tributary stream if the Planning Board finds that no other reasonable alternative exists further from the shoreline or tributary stream.
B. 
Parking areas shall be adequately sized for the proposed use and shall be designed to prevent stormwater runoff from flowing directly into a water body, tributary stream or wetland and, where feasible, to retain all runoff on site.
C. 
In determining the appropriate size of proposed parking facilities, the following shall apply:
(1) 
Typical parking space: approximately 10 feet wide and 20 feet long, except that parking spaces for a vehicle and boat trailer shall be 40 feet long.
(2) 
Internal travel aisles: approximately 20 feet wide.
A. 
No accumulation of slash shall be left within 50 feet of the normal high water mark of any pond, river or saltwater body as defined. At distances of greater than 50 feet from the normal high water mark of such waters and extending to the limits of the area covered by Chapter 140, Zoning, all slash shall be disposed of in such a manner that it lies on the ground and no part thereof extends more than four feet above the ground.

Within a strip of land extending 250 feet inland from the normal high-water line in a shoreland area zoned for resource protection abutting a great pond there shall be no timber harvesting except to remove safety hazards.
C. 
Except for water crossings, skid trails and other sites where the operation of machinery used in timber harvesting results in the exposure of mineral soil shall be located such that an unscarified strip of vegetation of at least 75 feet in width for slopes up to 10% shall be retained between the exposed mineral soil and the normal high-water line of a water body or wetland edge. For each ten-percent increase in slope, the un-scarified strip shall be increased by 20 feet. The provisions of this subsection apply only to a face sloping toward the water body or wetland; provided, however, that no portion of such exposed mineral soil on a back face shall be closer than 25 feet from the normal high water-line of a protected water body.
D. 
Timber harvesting operations shall be conducted in such a manner and at such a time that minimal soil disturbance results. Adequate provisions shall be made to prevent soil erosion and sedimentation of surface waters. Timber harvesting equipment shall not use stream channels as travel routes except when:
(1) 
Surface waters are frozen; and
(2) 
The activity will not result in any ground disturbance.
E. 
All crossings of flowing water shall require a bridge or culvert, except in areas with low banks and channel beds which are composed of gravel rock or similar hard surface which would not be eroded or otherwise damaged.
F. 
Skid trail approaches to water crossings shall be located and designed so as to prevent water runoff from directly entering the water body or stream. Upon completion of timber harvesting, temporary bridges and culverts shall be removed and areas of exposed soil revegetated.

(1) 
Selective harvesting of no more than 40% of the total volume of trees four inches or more in diameter measured at 4 1/2 feet above the ground level on any lot in any ten-year period is permitted. In addition:
(a) 
Within 100 feet, horizontal distance, of the normal high-water of a water body zoned for resource protection and within 100 feet, horizontal distance, of water bodies zoned for shoreland/slope and tributary streams, there shall be no clear-cut openings, and a well distributed stand of trees shall be maintained.
(b) 
At distances greater than 100 feet, horizontal distance, of any water resource zoned for resource protection and the Great Works and Salmon Falls rivers and greater than 100 feet, horizontal distance, of the water resources zoned for shoreland/slope, timber harvesting operations shall not create single openings in the forest canopy greater than the height of the average tree in the stand. Such openings shall be included in the calculation of total volume removal. For the purposes of these standards, volume may be considered to be equivalent to basal area.
H. 
Timber harvesting operations exceeding the 40% limitation in Subsection G(1) above may be allowed by the Planning Board upon a clear showing, including a forest management plan signed by a Maine-licensed professional forester, that such an exception is necessary for good forest management and will be carried out in accordance with the purposes of this chapter. The Planning Board shall notify the Commissioner of the Department of Environmental Protection of each exception allowed within 14 days of the Planning Board's decision.
A. 
Where feasible, the installation of essential services shall be limited to existing public ways and existing service corridors.
B. 
The installation of essential services, other than roadside distribution lines, is not allowed in a Resource Protection District, except to provide services to a permitted use within said district, or except where the applicant demonstrates that no reasonable alternative exists. Where allowed, such structures and facilities shall be located so as to minimize any adverse impacts on surrounding uses and resources, including visual impacts.
C. 
Damaged or destroyed public utility transmission and distribution lines, towers and related equipment may be replaced or reconstructed without a permit.
A. 
All new construction and development shall be designed to minimize stormwater runoff from the site in excess of the natural predevelopment conditions. Where possible, existing natural runoff control features, such as berms, swales, terraces and wooded areas, shall be retained in order to reduce runoff and encourage infiltration of stormwaters.
B. 
Stormwater runoff control systems shall be maintained as necessary to ensure proper functioning.
Any proposed land use activity involving structural development or soil disturbance on or adjacent to sites listed on, or eligible to be listed on, the National Register of Historic Places, as determined by the permitting authority, shall be submitted by the applicant to the Maine Historic Preservation Commission for review and comment at least 20 days prior to action being taken by the permitting authority. The permitting authority shall consider comments received from the Commission prior to rendering a decision on the application.
This section pertains to work to be carried out adjacent to, but not in, a minor freshwater wetland, as defined. Adjacent work includes depositing of fill, excavating, bulldozing and scraping the land when located within 100 feet of the normal high-water line of a minor freshwater wetland.
A. 
In order to prevent surface water which may carry sediment from the disturbance activity from directly entering a minor freshwater wetland:
(1) 
A twenty-five-foot undisturbed strip of vegetation shall be maintained between the normal high-water line and the activity; and
(2) 
Where sustained slopes exceed 20%, a one-hundred-foot undisturbed strip of vegetation shall be maintained between the normal high-water line and the activity.
B. 
These undisturbed buffer strip requirements do not apply to:
(1) 
Providing access to an approved use.
(2) 
Maintenance of existing roadways.
(3) 
Removal of underground storage tanks.
(4) 
Removal, replacement or maintenance of wastewater disposal systems.
(5) 
Placement and replacement of foundations and supports for legally existing or authorized structures.
