6.4   Shoreland Zone.

6.4.1. Purpose - Shoreland Zone: In order to make the Limington Zoning Ordinance conform to the laws of the State of Maine, a Shoreland Zone is hereby created.

6.4.2. Scope - Shoreland Zone: This Zone applies to any structure extending beyond the normal high-water line of a water body or within a wetland.

6.4.3. Nature and Effect - Shoreland Zone: The Shoreland Zone shall overlay the existing districts created by this ordinance, and its terms shall supersede any requirements of said underlying districts, unless the underlying requirements are more restrictive than those set forth here, in which case the more restrictive shall govern.

6.4.4. Districts - Shoreland Zone: The Shoreland Zone shall be divided into the following districts:

A. Shoreland Resource Conservation
B. Stream Protection
C. Residential
D. Commercial
E. Rural

6.4.5. Non-Conformance - Shoreland Zone: The Non-Conformance provisions of Article V of this Ordinance shall apply in the Shoreland Zone, as well as the following additional limitations on non-conforming structures:

A. Expansion of Portion of Non-Conforming Structure Within Setback: After January 1, 1989, if any portion of a structure is less than the required setback from the normal high-water line of a water body or the upland edge of a wetland, that portion of the structure shall not be expanded in floor area or volume by 30% or more during the lifetime of the structure.

B. Construction or Enlargement of Foundation: Construction or enlargement of a foundation beneath the existing structure shall not be considered an expansion of the structure provided: that the structure and new foundation are placed such that the setback requirement is met as nearly as is practical, as determined by the Planning Board, basing its decision on the criteria set forth in subsection D below; that the completed foundation does not extend beyond the exterior dimensions of the structure; and that the foundation does not cause the structure to be elevated by more than three (3) additional feet.

C. Expansion Toward Water Prohibited Within Setback. No structure which is less than the required setback from the normal high-water line of a water body or tributary stream, or from the upland edge of a wetland shall be expanded toward the water body, tributary stream or wetland.

D. Relocation: A non-conforming structure may be relocated within the boundaries of the parcel on which the structure is located provided that the site of relocation conforms to all setback requirements as nearly as is practical as determined by the Planning Board, and provided that the applicant demonstrates that the present subsurface sewage disposal system meets the requirements of State Law and the State of Maine Subsurface Waste water Disposal Rules (Rules), or that a new system can be installed in compliance with the said Law and Rules. In no case shall a structure be relocated in a manner that causes the structure to be more non-conforming.

In determining whether the building relocation meets setback requirements as nearly as is practical, the Planning Board shall consider the size of the lot, the slope of the land, the potential for soil erosion, the location of other structures on the property and on adjacent properties, the location of the septic system and other on-site soils suitable for septic systems, and the type and amount of vegetation to be removed to accomplish the relocation.

E. Reconstruction or Replacement: Any non-conforming structure which is located less than the required setback from the normal high-water line of a water body, tributary stream, or upland edge of a wetland, and which is removed, damaged or destroyed to an extent that exceeds 50% of the market value of the structure immediately before such removal, damage or destruction, may be reconstructed or replaced provided that a permit is obtained within one year of the date of said removal, damage or destruction, and provided that such reconstruction or replacement is in compliance with the water setback requirement of this Ordinance as nearly as is practical, as determined by the Planning Board. In making this determination, the Planning Board shall use the criteria set forth in subsection D above, and in addition, shall take into consideration the physical condition and type of foundation, if any, and the purpose of this Ordinance. In no case shall a structure be reconstructed or replaced so as to increase its non-conformity.

Any non-conforming structure which is damaged or destroyed (excluding normal maintenance and repair) to an extent less than or equal to 50% of the market value of the structure immediately before the damage or destruction may be reconstructed, in place, with a permit from the Code Enforcement Officer.

F. Change of Use of a Non-Conforming Structure: The use of a non-conforming structure may not be changed to another use unless the Planning Board, after receiving a written application, determines that the new use will have no greater adverse impact on the water body or wetland, or on the subject or adjacent properties and resources, than the existing use.

In determining whether greater adverse impact will occur, the Planning Board shall require written documentation from the applicant regarding the probable effects on public health and safety, erosion and sedimentation, water quality, fish and wildlife habitat, vegetative cover, visual and actual points of public access to waters, natural beauty, flood plain management, archaeological and historic resources, and functionally water-dependent uses.

6.4.6. Establishment of Districts - Shoreland Zone.

A. Resource Conservation District - Shoreland Zone.

In addition to any areas of the Resource Conservation District as defined in Section 4.3.B of this Ordinance that are also within the limits of the Shoreland Zone as described herein, the Resource Conservation District within the Shoreland Zone shall include areas in which development would adversely affect water quality, productive habitat, biological ecosystems or areas of particular scenic or natural value. This district includes the following areas when they occur within the limits of the Shoreland Zone (exclusive of the Stream Protection District), except areas which are already developed as of the date of enactment of this Ordinance and areas within the Commercial District.

11. Photographic processing.

12. Printing.

G. Parking Areas - Shoreland Zone.

1. Parking areas shall meet the shoreline setback requirements for structures in the District in which they are located, except that the setback requirements for parking areas serving public boat launching facilities in Districts other than the Commercial District may be reduced to no less than fifty (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.

2. Parking areas shall be adequately sized for the proposed use and shall be designed to prevent storm water runoff from flowing directly into a water body, and, where feasible, to retain all runoff on site.

3. In determining the appropriate size of proposed parking facilities, the following shall apply:

a. Typical parking space: approximately ten (10) feet wide and twenty (20) feet long, except that parking spaces for a vehicle and boat trailer shall be forty (40) feet long.

b. Internal travel aisles: approximately twenty (20) feet wide.

H. Roads and Driveways - Shoreland Zone.

The following standards shall apply to the construction of roads and/or driveways and drainage systems, culverts, and other related features:

1.

If no other reasonable alternative exists, the Planning Board may reduce the road and/or driveway setback requirement to no less than fifty (50) feet 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 twenty (20) percent the road and/or driveway setback shall be increased by ten (10) feet for each five (5) percent increase in slope above twenty (20) percent

This paragraph shall apply neither 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.

3. New roads and driveways are prohibited in the Resource Conservation and Stream Protection Districts 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 banks shall be no steeper than a slope of two (2) horizontal to one (1) vertical, and shall be graded and stabilized in accordance with the provisions for erosion and sedimentation control contained in subsection O.

5. Road grades shall be no greater than ten (10) percent except for short segments of less than two hundred (200) feet.

6. In order to prevent road surface drainage from directly entering water bodies, roads 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. Road 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 in the road or ditches gains sufficient volume or head to erode the road 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 at intervals no greater than indicated in the following table:
Road Grade (Percent)    Spacing (Feet)
0-2250
3-5200-135
6-10100-80
11-1580-60
16-2060-45
21+40

b. Drainage dips may be used in place of ditch relief culverts only where the road grade is ten (10) percent or less.

c. On road sections having slopes greater than ten (10) percent, ditch relief culverts shall be placed across the road at approximately a thirty (30) degree angle down slope from a line perpendicular to the centerline of the road.

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 stabilized with appropriate materials.

8. Ditches, culverts, bridges, dips, water turnouts and other storm water runoff control installations associated with roads shall be maintained on a regular basis to assure effective functioning.

I. Signs - Shoreland Zone.

The following provisions shall govern the use of signs in the Resource Conservation, Residential and Commercial Districts within the Shoreland Zone:

1. Signs relating to goods and services sold on the premises shall be permitted, provided that such signs shall not exceed six (6) square feet in area and shall not exceed two (2) signs per premises. Signs relating to goods or services not sold or rendered on the premises shall be prohibited.

2. Name signs shall be permitted, provided such signs shall not exceed two (2) signs per premises.

3. Residential users may display a single sign not over three (3) square feet in area relating to the sale, rental, or lease of the premises.

4. Signs relating to trespassing and hunting shall be permitted without restriction as to number provided that no such sign shall exceed two (2) square feet in area.

5. Signs relating to public safety shall be permitted without restriction.

6. No sign shall extend higher than twenty (20) feet above the ground.

7. Signs may be illuminated only by shielded, non-flashing lights.

J. Essential Services - Shoreland Zone.

1. Where feasible, the installation of essential services shall be limited to existing public ways and existing service corridors.

2. The installation of essential services is not permitted in the Shoreland Zone Resource Conservation District, except to provide services to a permitted use within said District, or except where the applicant demonstrates that no reasonable alternative exists. Where permitted, such structures and facilities shall be located so as to minimize any adverse impacts on surrounding uses and resources, including visual impacts.

K. Mineral Exploration and Extraction - Shoreland Zone.

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 one hundred (100) square feet of ground surface. A permit from the Code Enforcement Officer 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, so as to restore disturbed areas and to protect the public health and safety.

Mineral extraction may be permitted under the following conditions:

1. Unless authorized pursuant to the Natural Resources Protection Act, Title 38, M.R.S.A, Section 480-C no part of any extraction operation, including drainage and runoff control features shall be permitted within one hundred (100) feet of the normal high-water line of a great pond, and within seventy-five (75) feet of the normal high-water line of any other water body, tributary stream, or the upland edge of a wetland. Extraction operations shall not be permitted within seventy-five (75) feet of any property line, without written permission of the owner of such adjacent property.

2. All other requirements for extraction set forth in Article VIII are met.

L. Agriculture - Shoreland Zone.

1. All spreading or disposal of manure shall be accomplished in conformance with the Maine Guidelines for Manure and Manure Sludge Disposal on Land published by the University of Maine Soil and Water Conservation Commission in July, 1972.

2. Manure shall not be stored or stockpiled within one hundred (100) feet, horizontal distance, of a great pond or within seventy-five (75) feet horizontal distance, of other water bodies, tributary streams, or wetlands. Within five (5) years of the effective date of this ordinance all manure storage areas within the Shoreland Zone must be constructed or modified such that the facility produces no discharge of effluent or contaminated storm water. Existing facilities which do not meet the setback requirement may remain, but must meet the no discharge provision within the above five (5) year period.

3. Agricultural activities involving tillage of soil greater than forty thousand (40,000) square feet in surface area, or the spreading, disposal or storage of manure within the Shoreland Zone shall require a Soil and Water Conservation Plan to be filed with the Planning Board. Non-conformance with the provisions of said plan shall be considered to be a violation of this Ordinance.

4. There shall be no new tilling of soil within one-hundred (100) feet, horizontal distance, of the normal high-water line of a great pond; within seventy-five (75) feet, horizontal distance, from other water bodies; nor within twenty-five feet, horizontal distance, of tributary streams, and wetlands. Operations in existence on the effective date of this Ordinance and not in conformance with this provision may be maintained.

5. After the effective date of this Ordinance, newly established livestock grazing areas shall not be permitted within one hundred (100) feet, horizontal distance, of the normal high-water line of a great pond; within seventy-five (75) feet, horizontal distance of other water bodies; nor within twenty-five (25) feet, horizontal distance, of tributary streams and wetlands. Livestock grazing associated with ongoing farm activities, and which are not in conformance with the above setback provisions may continue, provided that such grazing is conducted in accordance with a Soil and Water Conservation Plan.

M. Timber Harvesting - Shoreland Zone.

1. Within the strip of land extending 75 feet inland from the normal high-water line in a Resource Conservation District abutting a great pond there shall be no timber harvesting, except to remove safety hazards.

2. Except in areas as described in Paragraph 1 above, timber harvesting shall conform with the following provisions:

a. Selective cutting of no more than forty (40) percent of the total volume of trees four (4) inches or more in diameter measured at 4 1/2 feet above ground level on any lot in any ten (10) year period is permitted. In addition:

i. Within one-hundred (100) feet, horizontal distance of the normal high-water line of a great pond and within seventy-five (75) feet, horizontal distance, of the normal high-water line of other water bodies, tributary streams, or the upland edge of a wetland, there shall be no clearcut openings, and a well-distributed stand of trees and other vegetation, including existing ground cover, shall be maintained.

ii. At distances greater than one-hundred (100) feet, horizontal distance, of a great pond classified GPA or a river flowing to a great pond, and greater than seventy-five (75) feet, horizontal distance, of the normal high-water line of other water bodies or the upland edge of a wetland, harvesting operations shall not create single clearcut openings greater than ten-thousand (10,000) square feet in the forest canopy. Where such openings exceed five-thousand (5000) square feet they shall be at least one hundred (100) feet apart. Such clearcut 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.

b. No accumulation of slash shall be left within fifty (50) feet of the normal high-water line of a water body. In all other areas slash shall either be removed or disposed of in such a manner that it lies on the ground and no part thereof extends more than four (4) feet above the ground. Any debris that falls below the normal high-water line of a water body shall be removed.

c. Timber harvesting equipment shall not use stream channels as travel routes except when:

i. Surface waters are frozen; and

ii. The activity will not result in any ground disturbance.

d. 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.

e. Skid trail approaches to water crossings shall be located and designed so as to prevent water runoff from directly entering the water body or tributary stream. Upon completion of timber harvesting, temporary bridges and culverts shall be removed and areas of exposed soil revegetated.

f. 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 seventy-five (75) feet in width for slopes up to ten (10) percent shall be retained between the exposed mineral soil and the normal high-water line of a water body or upland edge of a wetland. For each ten (10) percent increase in slope, the unscarified strip shall be increased by twenty (20) feet. The provisions of this paragraph 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 twenty five (25) feet from the normal high-water line of a water body or upland edge of a wetland.

N. Clearing of Vegetation for Development - Shoreland Zone.

1. Within a Shoreland Zone Resource Conservation District abutting a great pond, there shall be no cutting of vegetation within the strip of land extending 75 feet, horizontal distance, inland from the normal high-water line, except to remove safety hazards.

Elsewhere, in any Shoreland Zone Resource Conservation District the clearing of vegetation shall be limited to that which is necessary for uses expressly authorized in that district.

2. Except in areas as described in Paragraph 1, above, and except to allow for the development of permitted uses, within a strip of land extending one-hundred (100) feet, horizontal distance, inland from the normal high-water line of a great pond and seventy-five (75) 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:

a. There shall be no cleared opening greater than 250 square feet in the forest canopy as measured from the outer limits of the tree crown. However, a footpath not to exceed ten (10) feet in width as measured between tree trunks is permitted provided that a cleared line of sight to the water through the buffer strip is not created. Adjacent to a great pond or stream or river flowing to a great pond classified GPA, the width of the foot path shall be limited to six (6) feet.

b. Selective cutting of trees within the buffer strip is permitted provided that a well distributed stand of trees and other vegetation is maintained. For the purposes of this section a "well-distributed stand of trees and other vegetation" adjacent to a great pond or a river or stream flowing to a great pond shall be defined as maintaining a rating score of 12 or more in any 25-foot by 25-foot square (625 square feet) area as determined by the following rating system.

Diameter of Tree
at 4-1/2 feet Above
Ground Level (inches)
Points
2 - 4 in.1
>4 - 12 in.2
>12 in.4

Thus, if a 25-foot by 25-foot plot adjacent to a great pond contains trees worth a total of 20 points, trees worth a total of 8 points may be removed from the plot (20 - 8 = 12), provided that no cleared openings are created.

Adjacent to other water bodies, tributary streams, and wetlands, a "well-distributed stand of trees and other vegetation" is defined as maintaining a minimum rating score of 8 per 25-foot square area.

Notwithstanding the above provisions, no more than 40% of the total volume of trees four (4) inches or more in diameter, measured at 4 1/2 feet above ground level may be removed in any ten (10) year period.

c. In order to protect water quality and wildlife habitat adjacent to great ponds, and streams and rivers which flow to great ponds, existing vegetation under three (3) feet in height and other ground cover shall not be removed, except to provide for a footpath or other permitted uses as described in paragraphs 2 and 2a. above.

d. Pruning of tree branches, on the bottom 1/3 of the tree is permitted.

e. 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.

The provisions contained in paragraph 2 above shall not apply to those portions of public recreational facilities adjacent to public swimming areas. Cleared areas, however, shall be limited to the minimum area necessary.

3. At distances greater than one hundred (100) feet, horizontal distance, from a great pond and seventy-five (75) feet, horizontal distance, from the normal high-water line of any other water body, tributary stream, or the upland edge of a wetland, except to allow for the development of permitted uses, there shall be permitted on any lot, in any ten (10) year period, selective cutting of not more than forty (40) percent of the volume of trees four (4) 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 forty (40) percent calculation. For the purposes of these standards volume may be considered to be equivalent to basal area.

In no event shall cleared openings for development, including but not limited to, principal and accessory structures, driveways and sewage disposal areas, exceed in the aggregate, 25% of the lot area or ten thousand (10,000) square feet, whichever is greater, including land previously developed. This provision shall not apply to the Commercial District.

4. Cleared openings legally in existence on the effective date of this Ordinance may be maintained, but shall not be enlarged, except as permitted by this Ordinance.

5. Fields which have reverted to primarily shrubs, trees, or other woody vegetation shall be regulated under the provisions of this section.

O. Erosion and Sedimentation Control - Shoreland Zone.

1. All activities which involve filling, grading, excavation or other similar activities which result in unstabilized soil conditions and which require a permit shall require a written soil erosion and sedimentation control plan. The plan shall be submitted to the permitting authority for approval and shall include, where applicable, provisions for:

a. Mulching and revegetation of disturbed soil.

b. Temporary runoff control features such as hay bales, silt fencing or diversion ditches.

c. Permanent stabilization structures such as retaining walls or riprap.

2. In order to create the least potential for erosion, development shall be designed to fit with the topography and soils of the site. Areas of steep slopes where high cuts and fills may be required shall be avoided wherever possible, and natural contours shall be followed as closely as possible.

3. 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.

4. Any exposed ground area shall be temporarily or permanently stabilized within one (1) 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 (9) months of the initial date of exposure. In addition:

a. Where mulch is used, it shall be applied at a rate of at least one (1) bale per five hundred (500) square feet and shall be maintained until a catch of vegetation is established.

b. Anchoring the mulch with netting, peg and twine or other suitable method may be required to maintain the mulch cover.

c. 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.

5. Natural and man-made drainage ways and drainage outlets shall be protected from erosion from water flowing through them. Drainage ways shall be designed and constructed in order to carry water from a twenty five (25) year storm or greater, and shall be stabilized with vegetation or lined with rip-rap.

P. Soils - Shoreland Zone.

All land uses shall be located on soils in or upon which the proposed uses or structures can be established or maintained without causing adverse environmental impacts, including severe erosion, mass soil movement, improper drainage, and water pollution, whether during or after construction. Proposed uses requiring subsurface waste disposal, and commercial or industrial development and other similar intensive land uses, shall require a soils report based on an on-site investigation and be prepared by state-certified professionals. Certified persons may include Maine Certified Soil Scientists, Maine Registered Professional Engineers, Maine State Certified Geologists and other persons who have training and experience in the recognition and evaluation of soil properties. The report shall be based upon the analysis of the characteristics of the soil and surrounding land and water areas, maximum ground water elevation, presence of ledge, drainage conditions, and other pertinent data which the evaluator deems appropriate. The soils report shall include recommendations for a proposed use to counteract soil limitations where they exist.

Q. Water Quality - Shoreland Zone.

No activity shall deposit on or into the ground or discharge to the waters of the State any pollutant that, by itself or in combination with other activities or substances will impair designated uses or the water classification of the water body

R. Archaeological Sites - Shoreland Zone.

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 twenty (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.
