In considering applications for the subdivision of land, the Planning Board shall be guided by the standards set forth hereinafter. Said standards shall be considered to be minimum requirements and shall be waived by the Board only under circumstances set forth in §§ 146-24 through 146-26 herein.
A. 
Character of land. Land of such character that it cannot be used without danger to health or peril from fire, flood or other menace shall not be subdivided for residential purposes nor for such other uses as may increase danger to health, life or property or aggravate a flood hazard.
B. 
Conformity to Official Map and Village Plan. Subdivisions shall conform to the Official Map of the Village and shall be in harmony with such portions of the Village Plan as may be in existence from time to time.
C. 
Preliminary subdivision plat approval; stormwater pollution prevention plan. A stormwater pollution prevention plan (SWPPP) shall be required for preliminary subdivision plat approval. The SWPPP shall meet all performance and design criteria and standards in Chapter 67 of this Code. The approved preliminary subdivision plat shall be consistent with the provisions of Chapter 67 of this Code.
[Added 11-3-2010 by L.L. No. 4-2010]
D. 
Final subdivision plat approval; stormwater pollution prevention plan. A stormwater pollution prevention plan consistent with the terms of preliminary plan approval shall be required for final subdivision plat approval.

[Added 11-3-2010 by L.L. No. 4-2010]
A. 
Width, location and construction. Streets shall conform to Village Road and Drainage Standards as to width and construction, shall be suitably located to accommodate the prospective traffic and to afford access for fire-fighting, snow-removing and other road maintenance equipment and shall be coordinated so as to compose a convenient system. The arrangement of streets shall be such as to cause no undue hardship to adjoining properties.
B. 
Arrangement. The arrangement of streets in the subdivision shall provide for the continuation of principal streets of adjoining subdivisions and for proper projection of principal streets into adjoining properties which are not yet subdivided, in order to make possible necessary fire protection, movement of traffic and the construction or extension, presently or when later required, of needed utilities and public services such as sewers, water mains and drainage facilities, Where, in the opinion of the Planning Board, topographic or other conditions make such continuance undesirable or impracticable, the above requirements may be modified.
C. 
Minor streets. Minor streets shall be so laid out that their use by through traffic will be discouraged.
D. 
Special treatment along arterial streets. Where a subdivision abuts or contains an existing or proposed arterial street, the Board may require reverse frontage with screen planting contained in a nonaccess reservation along the rear property line, deep lots with rear access or such other treatment as may be necessary for adequate protection of residential properties and to afford separation of through and local traffic.
E. 
Provision for future subdivision. Where a tract is subdivided into lots substantially larger than the minimum size required in the zoning district in which a subdivision is located, the Board may require that streets and lots be laid out so as to permit future subdivision in accordance with the requirements contained in this chapter.
F. 
Reserve strips. Reserve strips or parcels of land controlling or prohibiting access to a street shall be prohibited.
G. 
Dead-end streets. The creation of dead-end or loop residential streets shall be encouraged whenever the Board finds that such type of development will not interfere with normal traffic circulation in the area, provided that interior parks are covered by appropriate covenants as to maintenance. In the case of dead-end streets, where needed or desirable, the Board may require the reservation of a twenty-foot-wide easement to provide for continuation of pedestrian traffic and utilities to the next street. Subdivisions containing 50 lots or more shall have at least two street connections with streets existing on the Official Map and open to traffic.
H. 
Intersections with major roads. Minor or secondary street openings into a major road shall, in general, be at least 500 feet apart.
I. 
Street jogs. Street jogs with center-line offsets of less than one 125 feet shall not be permitted except with the approval of the Planning Board.
J. 
Block design. The design of blocks shall be determined with due regard to preserving the semirural character of the Village. Curvilinear block patterns shall be encouraged, and due consideration in design shall be given to limitations and opportunities offered by topography, scenic views and other natural features. Blocks shall not be excessively long thereby causing unnecessarily circuitous travel on the streets. In long blocks, the Planning Board may require the reservation of a twenty-foot-wide easement through the block to provide for the crossing of underground utilities and pedestrian traffic where needed or desirable. In general, no block shall be less than 200 feet in width nor more than 1,200 feet in length.
K. 
Relation to topography. The street plan of a proposed subdivision shall bear a logical relationship to the topography of the property, and all streets shall be arranged so as to obtain as many of the building sites as possible at or above the grade of the streets.
L. 
Angle of intersection. Except where impracticable, all streets shall join each other so that for a distance of at least 100 feet the street is approximately at right angles to the street it joins.
M. 
Four cornered intersections. Cross (four-cornered) street intersections shall be avoided except where absolutely necessary and with the approval of the Planning Board.
A. 
Widths of right-of-way. Streets shall have a minimum width of 50 feet unless otherwise indicated on the Village Plan.
B. 
Improvements. Streets shall be graded and improved with pavement (conforming to Village road specifications), gutters, storm sewers or other drainage facilities and water mains, street trees, street signs, fire alarm signal devices and fire hydrants or fire wells, except where waivers may be requested, and the Planning Board may waive, subject to appropriate conditions, such improvements as it considers may be omitted without jeopardy to the public health, safety and general welfare. Such grading and improvements shall be approved as to design and specifications by the Village Engineer.
C. 
Utilities. The Planning Board may require or approve the location of utilities either in the street right-of-way between the paved roadway and street line or along rear property lines. All utilities shall be underground, including transformers and junction boxes.
D. 
Utility easement. Where utilities are not to be placed within street lines, perpetual unobstructed easements with satisfactory access to the street shall be provided in accordance with the specifications of the utility company or public authority having jurisdiction in the area. Where possible, easements shall be continuous from block to block and shall present as few irregularities as possible.
E. 
Grades. Grades of all streets shall conform in general to the terrain and shall not be less than 1% nor more than 10% for minor streets in residential zones.
F. 
Curve radius. All street intersection corners shall be rounded by curves of at least a thirty-foot radius. At curves, the inner street radius at the street line shall be 100 feet or more, depending upon the character of the street.
G. 
Dead-end and loop streets. Where dead-end streets are designed to be so permanently, they should, in general, not exceed 400 feet in length and shall terminate in a circular turnabout having a minimum radius of 50 feet.
H. 
Watercourses.
(1) 
Where a watercourse separates a proposed street from abutting property, provisions shall be made for access to all lots by means of culverts or other structures of design approved by the Village Engineer.
(2) 
Where a subdivision is traversed by a watercourse, drainageway, channel or stream, there shall be provided a stormwater easement or drainage right-of-way in no case less than 20 feet in width.
A. 
Type of name. All streets shown on a preliminary layout or subdivision plat shall be named. Streets shall have names and not numbers or letters (such as 1st, First or A Street).
B. 
Names to be substantially different. Proposed street names shall be substantially different so as not to be confused in sound or spelling with present names in the Village of North Haven, except that streets that join or are in alignment with streets of abutting or neighboring property shall bear the same name.
C. 
Street signs. Street signs, approved by the Planning Board as to material, design and location, shall be installed at all street intersections.
D. 
Design standards. All subdivision maps, whether standard design or cluster design, shall arrange lots and open space so as to preserve intact wooded areas, protect natural features (e.g., bluffs, trees, kettle holes, swales, slopes, wetlands and all other physical features which in the Planning Board's view are significant), locate new residential lots in a layout consistent with the enhancement of existing neighbors and adjacent areas, protect and preserve existing street viewsheds and vistas, establish buffers adjacent wetlands, watercourses, ponds and streams and protect slopes of 20% or greater.

[Added 11-5-2001 by L.L. No. 2-2001]
B. 
Side lines. All side lines of lots shall be at right angles to straight street lines and radial to curved street lines unless a waiver or modification of this rule will give a better street or lot plan.
C. 
Corner lots. Corner lots shall have extra width to permit appropriate orientation to both streets, and any structure placed thereon shall conform to the building setback line of each street.
D. 
Driveway access. Where practicable, lots shall be so laid out that the driveways have access to that street abutting the subdivision which carries or is intended to carry the lesser amount of traffic.
E.

[Added 7-5-2000 by L.L. No. 5-2000]
A. 
Parks, beaches and marinas shown on Village Plan. Where a proposed park, beach, marina or other public use shown on the Village Plan is located in whole or in part in a subdivision, the Board may require the dedication or reservation of such area within the subdivision in those cases in which the Board deems such requirements to be reasonable.
B. 
Parks and/or beaches not shown on Village Plan. The Planning Board shall require the dedication or reservation of sites of a character, extent and location suitable to the requirements created by such development for parks and/or beaches of 10% of the gross area of the subdivision. The Planning Board shall give due credit for the provision of open spaces reserved for the common use of all property owners within the proposed subdivision by covenants in the deeds. Generally, the minimum area of the contiguous open spaces acceptable in fulfillment of this requirement, whether for private or public use, shall be at least three acres. Open spaces with a lesser area may be approved by the Planning Board whenever it deems that the difference between the area offered and the area deemed acceptable may be made up in connection with the future subdivision of adjacent land.
C. 
Substitution of payments in lieu of land dedication for parks.
(1) 
In cases where, due to size, topography or location of the subdivision, the Planning Board finds that a suitable park or parks cannot be properly located in any such plat or is otherwise not practical, the Planning Board shall require as a condition to approval of any such plat a payment to the Village of a sum to be determined by the Board of Trustees, which sum shall constitute a trust fund known as the "Village Recreation Site Acquisition and Improvement Fund," to be used by the Board of Trustees exclusively for neighborhood parks, playgrounds or for recreational purposes, including acquisition of land.
(2) 
The amount required to be paid to the Village by the subdivider in lieu of land dedication for parks will be determined by the Board of Trustees. The basis for this fee will be the fair market value of the total gross area of the subdivision as unimproved land. The fair market value will exclude the current market value of the gross area of lots upon which are situated dwellings which are in existence at the time the subdivision application is made.
(3) 
The fair market value shall be determined by the Village Trustees in consultation with a licensed real estate broker retained by the Village. The fee for the appraisal shall be paid in advance to the Village. No part of the appraisal fee will be refundable.
(4) 
The basis for the amount to be paid to the Village in lieu of park land shall be 5% of the appraised fair market value. The park fee will be paid to the Village after final approval but prior to the endorsement by the officers of the Planning Board.
D. 
Sites for other public uses. The Board may also require a subdivider to set aside such areas as it may deem to be required for specific public uses other than parks. Upon failure of the proper authorities to purchase such site within one year after the date of the approval of the plat, the subdivider, upon application to the Board and approval of such application, shall be relieved of the responsibility of reserving such land for public purposes.
E. 
Land adjacent to waterfront. In the subdivision of lands adjoining the waters of Noyac Bay, Shelter Island Sound, Sag Harbor Cove or any natural or man-made connecting body of water, the Board may require the filing of covenants or granting of easements permitting residents of the subdivision access to specific sections of water frontage and use thereof for bathing or mooring of boats.
F. 
Preservation of natural features. The Planning Board may require the preservation of all natural features which add value to residential developments and to the community, such as large trees or groves, watercourses and ponds, beaches, historic sites and similar irreplaceable assets.
[Amended 9-1-1992 by L.L. No. 2-1992]
G. 
Calculation of park area. In no event shall land area excluded from lot area under §§ 146-15 and 163-26(A)(3) be included in the gross area of a subdivision for calculation of and identification of the 10% dedication of park area.
[Added 11-5-2001 by L.L. No. 2-2001]
H. 
Calculation of yield. The Planning Board shall in all events exclude from the determination of the number of lots allowed in a subdivision the area which is either dedicated to park area or reserved for park area, and in no event shall area required for park dedication be included as an area contributing to total lot yield.
[Added 11-5-2001 by L.L. No. 2-2001]
I. 
Mandatory preservation of open space. Whenever the gross lot area of a proposed subdivision equals or exceeds 15 acres, the application shall include a cluster plan in addition to a standard subdivision plan. The standard subdivision plan shall be used to calculate yield for the cluster plan, and the cluster plan shall provide for the preservation of open space equal to at least 50% of the gross lot area. The arrangement of the location of the lots and open space in a cluster plan shall be beneficial to both the potential subdivision residents and the public at large, and special consideration shall be extended the preservation of existing public vistas and viewsheds along public streets. Use of a cluster plan is mandatory on all applications for total gross lot area equaling or exceeding 15 acres.
