ARTICLE 3.  SPECIAL PROVISIONS

 

3.1.  Waterfront Vista Protection

 

3.1.1.  Statement of Purpose

 

The Planning and Zoning Commission has found that the loss of aquatic vistas, blocked by buildings and structures which obstruct views of the sea, destroys the very character of the Borough as a seaside community.  In keeping with the goals of the Plan of Conservation and Development, the Borough wishes to protect and enhance the remaining vistas of the sea, especially at the ends of east-west streets.

 

3.1.2.  Views and Scenic Vistas

 

3.1.2.1.  Buildings and structures shall be located in such a way as to provide the maximum views of the water from the nearest public street, and minimally, one straight-line uninterrupted, rectangular view lane per property shall be preserved which width is not less than the required side yard width for the district in which the property is located.  A view lane may also be designated as a side yard and thus serve a dual purpose.

 

3.1.2.2.  At the end of east-west streets, a straightline uninterrupted view lane to the water shall be preserved which width is at least seventy-five percent (75%) of the existing street right-of-way.

 

3.1.2.3.  There shall be no building or other permanent obstruction in said view lanes.  No obstruction by fences, shrubbery, or trees or other landscape features higher than four feet shall be placed in said view lane between the sea and the nearest public street.  All major shade trees must have their lowest branches at least six feet above the ground at time of installation.  Any fences so placed within said view lanes shall be “see through”.  Protective fences or railings which are part of a public pedestrian walkway may be built to a height not to exceed four feet.  Existing trees and shrubs within view lanes may be maintained and replaced in their present position pursuant to the requirements of this Section.

 

3.1.3.  Setbacks from Mean High Tide

 

No building, structure or use shall extend closer than forty feet from the mean high water line, except for direct water-related structures and uses as defined by the Connecticut Coastal Management Act, such as, but not limited to docks, marine railways, marine cranes, launching ramps, marine accessories and services, boat docking and storage, open space and recreation, except that off-street parking spaces shall be set back at least ten feet from the mean high water line.

 

3.2.  Landscape Requirements

 

3.2.1.  Statement of Purpose

 

The following standards are intended to enhance the appearance of the Borough and to protect property values through the preservation of existing vegetation and planting of new screening and landscaping material.  Specifically, these standards are intended to reduce excessive heat, glare and accumulation of dust; to provide privacy from noise and visual intrusion; and to prevent the erosion of the soil, excessive runoff of drainage water, and the pollution of our water bodies.

 

3.2.2.  General Requirements

 

The following shall apply to all commercial, industrial, or multi-family uses for which a site plan is required:

 

3.2.2.1.  Any portion of a developed lot or property which is not used for location of buildings, structures, accessory uses, off-street parking and loading areas, sidewalks or similar purposes shall be landscaped and maintained in such a manner as to minimize storm water runoff, sedimentation and erosion.  Maintenance of land in its natural state may be considered to be in conformance with this requirement.

 

3.2.2.2.  Landscaping, trees and plants required by these Regulations shall be planted and maintained in a healthy growing condition according to accepted horticultural practices.  Any landscaping, trees and plants which are in a condition that does not fulfill the intent of these Regulations shall be replaced by the property owner during the next planting season for the particular plant material.

 

3.2.2.3.  A screening fence or wall required by these Regulations shall be maintained by the property owner in good condition throughout the period of the use of the lot.

 

3.2.2.4.  All landscaping, trees and planting material adjacent to parking areas, loading areas, or driveways shall be properly protected by barriers, curbs, or other means from damage by vehicles.

 

3.2.2.5.  To the maximum extent possible, existing trees, vegetation and unique site features shall be retained and protected.  Existing healthy mature plant materials, especially trees, if properly located, shall be fully credited against the requirements of these Regulations.

 

3.2.2.6.  For all new landscaping, an ample variety and quantity of ornamental plants should be provided.  Local soil, water and climatic conditions should be considered when choosing landscape materials to create optimum conditions for survival of plantings, and to ensure that plantings will survive with a minimum amount of maintenance.

 

3.2.2.7.  Landscaping should serve to integrate the proposed development to the site.  If the terrain is uneven, the Commission will consider and may approve parking areas at different levels.  Preservation of existing landscape materials and landforms is desirable.

 

3.2.2.8.  Landscape composition should be complimentary to the scale and style of existing and proposed buildings.

 

3.2.2.9.  Plant species that are a public nuisance or cause litter shall be avoided.  When landscaping is to be installed in areas where the general public will frequent, trees and bushes with sharp needles or thorns shall be avoided.

 

3.2.2.10.  All materials installed in conformance with the landscaping requirements of these Regulations shall meet the following minimum standards:  all deciduous trees shall have a minimum caliper of two and one half inches and a minimum height of six feet; all evergreen trees shall have a minimum height of six feet; and all shrubs shall be of a size at least one-third of their mature potential.

 

3.2.3.  Front Landscaped Area

 

For all commercial, industrial, or multi-family uses where a site plan is required, where appropriate the Commission may require a front landscaped area.  Reuse of an existing structure located less than ten feet from the front lot line is exempt from this requirement.  The front landscaped area shall extend the full width of the lot along the interior side of the front lot line, except where driveway exits and entrances are located.  The width of the front landscaped area shall be no less than ten feet.  The front landscaped area shall be covered with grass or other ground cover, and shall include appropriate trees and shrubs.  The purpose of the front landscaped area is to enhance the appearance of the use of the site, but not to screen the use from view.

 

3.2.4.  Landscaped Perimeter Area

 

For all commercial, industrial, or multi-family uses for which a site plan is required, a ten-foot wide landscaped perimeter area shall be provided along all lot lines other than the front lot line.  New single and two-family dwellings, reuse of existing buildings and structures which are located less than ten feet from a property line, and the waterfront side of a waterfront site are exempt from this requirement.  The landscaped perimeter area shall be covered with grass or other ground cover, and shall include appropriate trees and shrubs.  Where screening is required by the Commission as part of a site plan, the landscaped perimeter area may be planted as a screen.

 

3.2.5.  Landscaped Parking Areas

 

In addition to landscaped front and perimeter area requirements, parking areas shall comply with the following minimum standards:

 

3.2.5.1.  All uses required to provide twenty or more off-street parking spaces shall have at least ten square feet of interior landscaping within the paved portion of the parking area for each parking space.  Islands shall be required to indicate and assure safe and efficient channelization of both pedestrian and vehicular traffic and to separate the major access ways through the parking area from parking aisles.  Each separate landscaped area shall contain a minimum of one hundred square feet, shall have a minimum dimension of at least eight feet, and shall be planted with grass, shrubs, or trees.  Interior landscaping should be positioned so as to enhance the visual qualities of the site and to visually break up large expanses of pavement.

 

3.2.5.2.  A landscaped area shall be provided along the perimeter of any parking area except where the parking area is functionally integrated with an adjoining parking area on an abutting lot.  The landscaped areas shall have a minimum dimension of five feet, shall be planted with grass or shrubs, and shall include at least one deciduous tree for every fifty feet along the perimeter of the parking area.  Where appropriately located, the required front landscaped areas and landscaped perimeter areas of the lot may be used to satisfy this requirement.

 

3.2.6.  Submission of a Landscape Plan

 

As part of, or in conjunction with, a required site plan, a landscape plan shall be submitted meeting the informational requirements of Section 9.5.4, and demonstrating that a proposed development is in conformance with the requirements of Section 3.2 and Section 9.6.4 of these Regulations.

 

3.2.7.  Waiver of Landscape Requirements

 

The Commission may allow the reduction or elimination of a required landscaped area if the Commission finds a better site plan will result.

 

3.3.  ENVIRONMENTAL PROTECTION

 

3.3.1.  Coastal Area Management

3.3.2.    Flood Protection

 

Warning and Disclaimer of Liability.  THE DEGREE OF FLOOD PROTECTION REQUIRED BY THESE REGULATIONS IS CONSIDERED THE MINIMUM REASONABLE FOR REGULATORY PURPOSES AND IS BASED ON SCIENTIFIC AND ENGINEERING CONSIDERATIONS.  FLOODS OF GREATER MAGNITUDE CAN AND WILL OCCUR ON RARE OCCASIONS.  FLOOD HEIGHTS MAY BE INCREASED BY MAN-MADE OR NATURAL CAUSES.  THESE REGULATIONS DO NOT IMPLY THAT LAND OUTSIDE THE SPECIAL FLOOD HAZARD AREAS OR USES PERMITTED WITHIN SUCH AREAS WILL BE FREE FROM FLOODING OR FLOOD DAMAGES.  THESE REGULATIONS SHALL NOT CREATE LIABILITY ON THE PART OF THE BOROUGH OF STONINGTON OR ANY OFFICER OR EMPLOYEE THEREOF FOR ANY FLOOD DAMAGES THAT RESULT FROM RELIANCE ON THESE REGULATIONS OR ANY ADMINISTRATIVE DECISION LAWFULLY MADE THEREUNDER.

 

3.3.2.1.  Purpose of Special Requirements

 

Flood hazard areas, as designated on the Federal Flood Insurance Rate Map for the Borough of Stonington, are subject to periodic inundation which may result in loss of life and property, or in health and safety hazards.  These special regulations are designed to prevent or minimize loss of life, injuries, property damage, and other losses, both private and public; to promote the health, public safety and general welfare of the people; to help control and minimize the extent of floods, and reduce the depth and violence of flooding.

 

3.3.2.2.  For purposes of this section the following terms are defined herein:

 

a.  Area of Special Flood Hazard:  The area within a community subject to a one percent or greater chance of flooding in any given year, as identified on the community’s Flood Insurance Rate Map (FIRM) to August 2, 1995 and as may be amended from time to time.

 

b.  Coastal High Hazard Area:  An area of special flood hazard extending from offshore to the inland limit of a primary frontal dune along an open coast and any other area subject to high-velocity wave action from storms or seismic sources.

 

c.  Flood Insurance Rate Map (FIRM):  An official map of Stonington Borough on which the Federal Emergency Management Agency (FEMA) has delineated both the areas of special flood hazard and the applicable risk premium zones.

 

d.  Flood Insurance Study (FIS):  The official report by FEMA which contains flood profiles, the water surface elevation of the base flood, and other flood data.

 

e.  Functionally Dependent Use:  A facility or use which cannot be used for its intended purpose unless it is located in close proximity to water, such as a docking or port facility necessary for the loading and unloading of cargo or passengers, ship building, ship repair, or seafood processing facilities.  The term does not include long-term storage, manufacturing, sales, or servicing facilities.

 

f.  Lowest Floor:  The lowest floor of the lowest enclosed area (including basement).  An unfinished or flood resistant enclosure, usable solely for parking of vehicles, building access or storage, in an area other than a basement area is not considered a building’s lowest floor, provided that such an area fully meets the requirements of Section 3.3 of these Regulations.

 

g.  High Tide Lines:  A line or mark left upon tide flats, beaches, or along shore objects that indicates the intersection of land with the water’s surface at the maximum height reached by a rising tide.  The mark may be determined by:  (1) a line of oil or scum along shore objects; (2) a more or less contiguous deposit of fine shell or debris on the foreshore or berm; (3) physical markings or characteristics, vegetation lines, tidal gauge; or (4) by any other suitable means delineating the general height reached by a rising tide.  The term includes spring high tides and other high tides that occur with periodic frequency, but does not include storm surges in which there is a departure from the normal or predicted reach of the tide due to the piling up of water against a coast by strong winds such as those accompanying a hurricane or other intense storm.

 

h.  New Construction:  Structures for which the start of construction commenced on or after September 1, 1979; includes any subsequent improvements to such structures.

 

i.  Start of Construction:  (For other than new construction or substantial improvements under the Coastal Barrier Resources Act [P.L. 97-347]).  Includes substantial improvement, and means the date the building permit was issued, provided the actual start of construction, repair, reconstruction, or improvement was within one hundred eighty days of the permit date.  Should the permittee fail to commence work within this time frame, a new permit shall be required.  The actual start means the first placement of permanent construction of a structure (including a manufactured home) on a site, such as the pouring of slabs or footings, installation of piles, construction of columns, or any work beyond the stages of excavation or 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 a 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 the construction means the first alteration of any wall, ceiling, floor, or any other structural part of a building, whether or not that alteration affects the external dimensions of the building.

 

j.  Substantial Damage:  Damage of any origin sustained by a structure whereby the cost of restoring the structure to its before-damaged condition would equal or exceed fifty percent (50%) of the market value of the structure before the damage occurred.

 

k.  Substantial Improvements:  Any combination of repairs, reconstruction, alteration or improvements to a structure taking place over a three-year period in which the cumulative cost equals or exceeds fifty percent (50%) of the market value of the structure.  The market value of the structure should be:  (1) the appraised value of the structure prior to the start of the initial repair or improvement; or (2) in the case of damage, the value of the structure prior to the damage occurring.  For the purposes of this definition, “Substantial Improvement” is considered to occur when the first alteration of any wall, ceiling, floor, or other structural part of the building commences, whether or not that alteration affects the external dimensions of the structure.  The term does not, however, include any improvement project required to comply with existing health, sanitary, or safety code specifications which are solely necessary to assure safe living conditions.

 

l.  Water Surface Elevation:  The height, in relation to the National Geodetic Vertical Datum (NGVD) of 1929, (or other datum, where specified) of floods of various magnitudes and frequencies in the floodplains of coastal or riverine areas.

 

3.3.2.3.  Identification of Flood Hazard Areas and Flooding Elevation

 

Flood hazard areas and flood elevations shall be those identified by the Federal Flood Insurance Administration in a report entitled “The Flood Insurance Study for the Borough of Stonington”, dated May 1, 1979, and by the report entitled “Flood Insurance Study, Supplement Wave Height Analysis, Borough of Stonington, Connecticut”, dated July 5, 1983, and its accompanying Flood Insurance Rate Map, revised August 2, 1995 and may be revised from time to time.  This map is hereby adopted by reference and declared to be a part of these Regulations.  The Flood Insurance Study and the Supplement are on file in the office of the Borough Clerk.

 

3.3.2.4.  Zoning Permit Required

 

Before any construction, substantial improvement or development is begun within designated flood hazard areas, a Certificate of Zoning Compliance shall be obtained from the Commission or its designated agent in order to determine whether such activity is consistent with the need to minimize flood damage within the flood prone area. Special consideration shall be given to the placement of public utilities and the provision of adequate drainage to reduce exposure to flood hazards.

 


3.3.2.5.  Additional Information Required

 

In addition to information required by other provisions of the Zoning Regulations, applicants for activities with flood hazard areas shall provide the following:

 

a.  In A, AE, and A1-30 zones the elevation (in relation to mean sea level) of the lowest floor (including basement) of all new and substantially improved structures; in V, VE, and V1-30 zones the elevation (in relation to mean sea level) of the bottom of the lowest structural member of the lowest floor; and for floodproofed non-residential buildings the elevation to which the building is floodproofed.

 

b.  Identity of the flood hazard zone and base flood elevation from the Flood Hazard Rate Map.

 

c.  Any other such data as the Commission may require in order to determine compliance with Flood Hazard Area Requirements.

 

d.  Permits from those government agencies from which approval is required by federal or state law, if applicable.

 

3.3.2.6.  Construction Requirements

 

a.  All new construction, including prefabricated buildings, within A or V zones shall be anchored to prevent flotation and lateral movement, and shall be constructed with flood resistant materials and methods.

 

b.  All new construction and substantial improvements shall be constructed with electrical, heating, ventilation, plumbing, airconditioning equipment, and other service facilities located so as to prevent water from entering or accumulating within the components during conditions of flooding.

 

c.  Any new construction or substantial improvements in existing residential structures within A zones shall have the lowest floor, excluding pilings or columns, elevated to or above the base flood level.  All new non-residential construction and substantial improvement to non-residential construction shall have the lowest floor, including the basement, elevated or flood proofed to or above the base flood elevation.  Where flood proofing is used in lieu of elevating, the applicant shall present a plan certified by a professional engineer or architect registered in the State of Connecticut showing flood proofing methods are adequate to withstand the forces associated with the base flood.  For the purposes of this section, a breakaway wall shall have a design safe loading resistance of not less than ten and no more than twenty pounds per square foot (PSF).  Use of breakaway walls which exceed the design safe loading resistance of twenty PSF may be permitted only when a registered professional engineer or architect certifies that the design proposed meets the following conditions:  (1) collapse shall result from a water load less than that which would occur during the base flood; and (2) the elevated portion of the building and supporting foundation system shall not be subject to collapse, displacement, or other structural damage due to the effects of wind and water loads acting simultaneously on all building components during the base flood event.  Water loading values used shall be those associated with the base flood.  Wind loading values shall be those required by applicable state or local building standards.  Such enclosed space shall be usable solely for the parking of vehicles, building access, or limited storage.

 

d.  Any construction in a V zone shall be elevated and secured to adequately anchored pilings and columns so that the lowest portion of the structural members of the lowest floor, including pilings or columns, is elevated to or above the base flood level. Construction shall be certified by a registered professional engineer or architect to be secured to adequately anchored pilings in such a way that it will withstand velocity waters and wave wash.  Construction shall have space below the lowest floor free of obstruction, or constructed with breakaway walls intended to collapse under stress without jeopardizing the structural support of the building.

 

e.  All construction in a V zone shall be landward of the reach of mean high tide.

 

f.  Fill shall not be used for structural support of buildings in a V zone.

 

g.  A recreational vehicle stored within zones A1-30, AH, AE, V, VE, and V1-30 shall be fully licensed and ready for highway use.  It is ready for highway use if it is on its wheels or jacking system and is attached to the site only by quick disconnect type utilities and security devices.

 

h.  Within all A, AE, A1-30, V, VE, and V1-30 zones, all new and replacement water supply systems shall be designed to minimize or eliminate infiltration of flood waters into the system.  All new and replacement sanitary sewer systems shall be designed to minimize or eliminate infiltration of flood waters into the system and discharges from the system into flood waters.  On-site waste disposal systems shall be located to avoid impairment to them or contamination from them during flooding.

 

i.  New construction or substantial improvement of residential and non-residential buildings in zones A, AE, and A1-30 that include fully enclosed areas formed by foundation and other exterior walls below the base flood elevation shall have at least one side at or above surface grade and shall be designed to allow for the automatic entry and exit of flood waters to equalize hydrostatic flood forces on exterior walls.  Designs for complying with this requirement must either be certified by a registered professional engineer or architect or meet the following minimal criteria:  (1) provide a minimum of two openings having a total net area of not less than one square inch for every square foot of enclosed area subject to flooding; (2) the bottom of all openings shall be no higher than one foot above grade and at least one placed on the side of the lowest grade; and (3) openings may be equipped with screens, louvers, valves or other coverings or devices provided that they permit the automatic flow of flood waters in both directions.  Electrical, plumbing, and other utilities are prohibited below the base flood elevation.  Use of the enclosed area shall be limited to parking, building access and limited storage.

 

3.3.2.7.  The Planning and Zoning Commission shall review and decide all requests for variances and waivers from the requirements in these flood plain regulations (applicable to Section 3.3.2 only) including Specific Situation Variances:

 

a.  Buildings on an Historic Register

 

Variances may be issued for the reconstruction, rehabilitation or restoration of structures listed on the National Register of Historic Places or the State Inventory of Historic Places without regard to the procedures set forth in the remainder of this section, except for Section 3.3.2.6, provided the proposed reconstruction, rehabilitation, or restoration will not result in the structure losing its historical character.

 

b.  Pre-Existing Small Lot Location

 

Variances may be issued by the Commission for new construction and substantial improvements to be erected on a lot of one-half acre or less in size contiguous to and surrounded by lots with existing structures constructed below the base flood level in conformance with Section 3.3.2.6.

 

c.  Functional Dependent Uses

 

Variances may be issued for new construction and substantial improvements and other development necessary for the conduct of a functionally dependent use provided the structure or other development is protected by methods that minimize flood damage, create no additional threat to public safety, and meet the requirements of Section 3.3.2.6.

 

3.3.2.8.  Considerations for Granting of Variances

 

In passing upon such applications, the Commission shall consider all technical evaluations, all relevant factors, all standards specified in other sections of these Regulations and:

 

a.  The danger that materials may be swept onto other lands to the injury of others.

 

b.  The danger to life and property due to flooding or erosion damage.

 

c.  The susceptibility of the proposed facility and its contents to flood damage and the effect of such damage on the individual owner.

 

d.  The importance of the services provided by the proposed use.

 

e.  The necessity of the facility to waterfront location in the case of a functionally dependent facility.

 

f.  The availability of alternative locations, not subject to flooding or erosion damage, for the proposed use.

 

g.  The compatibility of the proposed use with existing and anticipated development.

 

h.  The relationship of the proposed use in the plan of development and flood plain management for that area.

 

i.  The safety of access to the property in times of flood for ordinary and emergency vehicles.

 

j.  The expected heights, velocity, duration, rate of rise and sediment transport of the flood waters and the effects of wave action, if applicable, expected at the site.

 

k.  The costs of providing governmental services during and after flood conditions, including maintenance and repair of public utilities and facilities such as sewers, gas, electrical and water systems, and streets and bridges.

 

3.3.2.9.  Upon consideration of the factors listed and the purposes of these Regulations, the Commission may attach such conditions to the granting of variances as it deems necessary to further the purposes of these Regulations.

 

3.3.2.10.  Conditions for Variances

 

Variances shall only be issued upon:  (1) a showing of good and sufficient cause, (2) a determination that a failure to grant the variance would result in exceptional hardship, and (3) a determination that the granting of a variance will not result in increased flood heights, additional threats to public safety, fraud on or victimization of the public, or conflict with existing local laws and ordinances.  Variances shall not be issued if any increase in flood levels during the base flood discharge would result.  Variances shall only be issued upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief and, in the instance of an historic building, a determination that the variance is the minimum necessary so as not to destroy the historic character and design of the building.

 

3.3.2.11.  The Borough of Stonington shall provide written notice to any applicant to whom a variance is granted, specifying the difference between the base flood elevation and the elevation to which the structure is to be built and stating that the cost of flood insurance will be commensurate with the increased risk resulting from the reduced lowest floor elevation up to amounts as high as $25.00 for $100.00 of insurance coverage..

 

3.3.3.  Erosion and Sediment Control Plan

 

In accordance with Section 22a-325 to 22a-329 inclusive of the Connecticut General Statutes, a soil erosion and sediment control plan shall be submitted with any application for development when the disturbed area of such development is cumulatively more than one half acre.  Disturbed area is defined as an area where ground cover is destroyed or removed leaving the land subject to accelerated erosion.  The soil and erosion control plan shall be mapped and in narrative form, and contain proper measures to be taken to control erosion and sedimentation both during and after construction.  The erosion and sediment control plan shall be based on the “Connecticut Guidelines for Soil Erosion and Sediment Control”, available from the Council on Soil and Water Conservation of the State of Connecticut.

 

3.3.3.1.  Contents of the Plan

 

The erosion and sediment control plan, at a scale of not less than one inch equals twenty feet (1”=20’), shall include the following:

 

a.  Locations and description of proposed development and adjacent properties.

 

b.  Locations of areas to be stripped of vegetation, areas to be re-graded, and contour data indicating existing and proposed grades, and existing wetlands and watercourses.

 

c.  A schedule of operations, including the sequence of major improvement phases such as clearing, grading, paving, installation of drainage features, utilities and the like.

 

d.  Seeding, sodding or re-vegetation plan and specifications for all unprotected or un-vegetated areas.

 

e.  Location, design and timing of sedimentation and erosion control measures such as diversion, waterways, grade stabilization structures, debris basin, storm water management control measures, and the like.  The narrative shall indicate design criteria used in the design of the control measures.

 

f.  A description of procedures to be followed to maintain sediment control measures during and after construction.

 

g.  Identity of the developer’s representative responsible for monitoring control measures during construction.

 

h.  The plan map shall show the words “Erosion and Sediment Plan” with space for the date and signature of the Commission Chairman or Secretary.

 

3.3.3.2.  Commission Vote Required

 

After review of the plan by the Commission or its designated agent, the Commission shall vote to certify, to modify and certify, or deny that the soil erosion and sediment control plan complies with these Regulations.  A vote of the Commission to approve a zoning application or Special Permit shall imply approval of the erosion and sediment control plan as well.

 


3.3.3.3.  Inspection During Construction

 

The Commission, through its members, agents, and consultants, shall periodically inspect construction projects for which erosion and sediment control plans have been certified to verify that erosion and sediment controls are consistent with the certified plan.

 

3.3.4.  Building Grades

 

Any building requiring yard space under these Regulations shall be located at such elevation that a sloping grade shall be maintained to cause the flow of surface water to run away from the walls of the building.

 

3.3.5.  Excavation and Filling of Earth Products

 

3.3.5.1.  Purpose

 

The Commission finds that the Borough of Stonington is characterized by the following conditions:  high residential density; a unique number of historic, landmark buildings and sites; generally small lot and parcel sizes; narrow streets and poor access to the Borough; all property is within the coastal boundary; the presence of numerous tidal and inland wetlands, generally shallow soils, and shallow depth to bedrock in most areas; proximity to valuable commercial shellfish beds; and other conditions enumerated in the Plan of Conservation and Development.  Therefore, the conduct of excavation and filling operations within the Borough must be severely limited in scope, intensity, and frequency.

 

3.3.5.2.  Prohibited Excavation and Filling Operations

 

Any removal or filling of earth products from or upon any land or water area, other than for the purposes enumerated in Section 3.3.5.3 below, is prohibited.  Earth products include, but are not limited to, stone, sand, gravel, loam, topsoil, peat, clay, and the like.

3.7.  Unified Sign Regulation

 

3.7.1.  Statement of Purpose

 

An important goal of the Plan of Conservation and Development is the

preservation of the character of the Borough of Stonington.  The Commission has found that, in other communities, one of the features which is most destructive of historic areas and their architectural character is the placement of signs which are inappropriate in size, color, illumination, or location.  These Unified Sign Regulations are designed to permit signs which are adequate to identify buildings and sites which are of interest to the public, but insure that they are of such design as will meet the objectives of the Plan of Conservation and Development.

 

3.7.2.  Definitions

 

3.7.2.1.  Sign:  Any structure, or part thereof, or any device attached to a building or structure, or painted or represented thereon, which displays or includes letters, words, symbols, trademarks, or any other graphic representation which is in the nature of any announcement, direction, or advertisement for commercial purposes or otherwise; similarly, any natural object, such as a tree, stone, or the earth itself, which is painted or arranged so as to represent or display any of the aforesaid graphic representations; any building feature, including roof or other special illumination, special colors or effects, or building or rooflines which serve to identify the use or occupancy of any building or site through a recognized motif or symbol.  The term “sign” shall not include the flag of any recognized nation, state, or other political unit.

 

3.7.2.2.  Sign Face:  The sign face is a plane defined by one continuous perimeter of that rectangle, triangle, or circle having the smallest area which encompasses all lettering, working, design, or symbols together with any background, different from the balance of wall on which it is located, if such background is designed as an integral part of and related to the sign.  Such perimeter, however, shall not include any structural elements lying outside the limits of such sign and not forming an integral part of the display.  For the purposes of these Regulations, two-sided signs shall be considered to have one face.

3.7.5.  Non-Residential Districts, Maximums

 

There shall be a maximum of one sign per street frontage for each non-residential use, except that a site or building containing more than one use may, in addition, display one sign per frontage for the entire site or building.  Each sign in non-residential districts shall have a maximum area of twelve square feet, provided, however, that the total gross area for all signs on any lot shall not exceed one square foot for each linear foot of building facing the street, or in the absence of any building, one-half square foot for each linear foot of lot frontage on the street, but in no case more than forty-eight square feet of gross sign area.  Signs on non-residential buildings or lots having more than one use shall be of uniform character, illumination, and general design for each such building or lot.
