In considering applications for 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 Article V herein.
A. 
Character of land. Land to be subdivided shall be of such character that it can be used safely for building purposes without danger to health or peril from fire, flood or other menace.
B. 
Conformity to Official Map and Comprehensive Plan. Subdivision shall conform to the Official Map of the Village and shall be in harmony with the Comprehensive Plan and Chapter 225, Zoning.
C. 
Specifications for required improvements. All required improvements shall be constructed or installed to conform to the Village specifications, as amended, which may be obtained from the Village Engineer.
A. 
Width, location and construction. Streets shall be of sufficient width, suitably located, and adequately constructed to comply with Village specifications, to conform to the Comprehensive Plan and to accommodate the prospective traffic and afford access for fire-fighting, snow removal and other road maintenance equipment. The arrangement of streets shall be such as to cause no undue hardship to adjoining properties and shall be coordinated so as to compose a convenient system.
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 and drainage facilities. Where, in the opinion of the Planning Board, topographic or other conditions make such continuance undesirable or impracticable, the above conditions 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 major streets. When a subdivision abuts or contains an existing or proposed major street, the Board may require marginal access streets, reverse frontage with screen planting contained in a nonaccess reservation along the rear property line, deep lots with rear service alleys, 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 resubdivision. 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 resubdivision in accordance with the requirements contained in this chapter.
F. 
Dead-end streets. The creation of dead-end or loop residential streets will be encouraged wherever the Board finds that such type of development will not interfere with normal traffic circulation in the area. 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 20 lots or more shall have at least two street connections with existing public streets, or streets shown on the Official Map, or streets on an approved subdivision plat for which a bond has been filed.
G. 
Block size. Blocks generally shall not be less than 400 feet nor more than 1,200 feet in length. In general, no block width shall be less than twice the normal lot depth. In blocks exceeding 800 feet in length, 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 and may further specify, at its discretion, that a four-foot-wide paved footpath be included.
H. 
Intersection with collector or major roads. Minor or secondary street openings into such roads shall, in general, be at least 500 feet apart.
I. 
Street jogs. Street jogs with center-line offsets of less than 125 feet shall be avoided.
J. 
Angle of intersection. In general, 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.
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. Grades of streets shall conform as closely as possible to the original topography.
A. 
Widths of rights-of-way. Streets shall have the following widths. (When not indicated on the Comprehensive Plan or Official Map, the classification of streets shall be determined by the Board.)
Minimum Right-of-Way
(feet)
Minimum Pavement
(feet)
Major streets
66
40
Collector or minor streets
60
32
B. 
Improvements. Streets shall be graded and improved with pavements, curbs and gutters, sidewalks, storm drainage facilities, water mains, sewers, streetlights and signs, landscaping and fire hydrants to comply with Village specifications, 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 public health, safety and general welfare. Pedestrian easements shall be approved as required by the Village Engineer. Such grading and improvements shall be approved as to design and specifications by the Village Engineer.
(1) 
Fire hydrants. Installation of fire hydrants shall be in conformity with all requirements of standard thread and nut as specified by the New York Fire Insurance Rating Organization and the Office of Fire Prevention and Control of the State of New York.[1]
[1]
Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. II).
(2) 
Streetlighting facilities. Lighting facilities shall be in conformance with the lighting system of the Village. Such lighting standards and fixtures shall be installed after approval by the appropriate power company and the authorized Village electrical inspector.
(3) 
Landscaping. Each lot shall have a minimum of one deciduous tree for every 50 linear feet of frontage or portion thereof. Trees shall be spaced generally evenly along and three feet within the front lot line or as directed by the Planning Board. In addition, one additional tree for each 22,000 square feet of lot area or portion thereof shall be planted on each lot. Tree planting shall not interfere with the normal placement of structures or drives and generally shall be within the front yard.
(a) 
Minimum tree size shall be a height of eight feet and a trunk diameter of 2 1/2 inches, measured 12 inches above the ground. Acceptable trees shall be varieties of oak, maple, linden, ash and thornless varieties of honeylocust or as approved by the Planning Board.
(b) 
Trees shall conform to latest edition of Horticultural Standards of the American Association of Nurserymen and shall be typical of their species or variety with normal habit of growth and healthy, well-developed root systems, free of disease and insect pests, and shall be guaranteed for one year from date of planting.
C. 
Utilities in streets. The Planning Board shall, wherever possible, require that underground utilities be placed in the street right-of-way between the paved roadway and street line to simplify location and repair of lines when they require attention. The subdivider shall install underground service connections to the property line of each lot within the subdivision for such required utilities before the street is paved.
D. 
Utility easements. Where topography is such as to make impractical the inclusion of utilities within the street rights-of-way, perpetual unobstructed easements at least 20 feet in width shall be otherwise provided with satisfactory access to the street. Wherever possible, easements shall be continuous from block to block and shall present as few irregularities as possible. Such easements shall be cleared and graded where required.
E. 
Grades. Grades of all streets shall conform in general to the terrain and shall not be less than 1/2% nor more than 6% for major or collector streets or 10% for minor streets in residential zones, but in no case more than 3% within 50 feet of any intersection.
F. 
Changes in grade. All changes in grade shall be connected by vertical curves of such length and radius as meet with the approval of the Village Engineer so that clear visibility shall be provided for a safe distance.
G. 
Dead-end streets (culs-de-sac). Where dead-end streets are designed to be so permanently, they should provide access to not more than 10 lots and shall terminate in a circular turnaround having a minimum right-of-way radius of 60 feet and pavement radius of 50 feet. At the end of temporary dead-end streets, a temporary turnaround with a pavement radius of 50 feet shall be provided, unless the Planning Board approves an alternate arrangement.
H. 
Watercourses.
(1) 
Where a watercourse separates a proposed street from abutting property, provision 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 as required by the Village Engineer and in no case less than 20 feet in width.
I. 
Curve radii. In general, street lines within a block, deflecting from each other at any one point by more than 10º, shall be connected with a curve, the radius of which, for the center line of the street, shall not be less than 400 feet on major streets, 200 feet on collector streets and 100 feet on minor streets.
J. 
Service streets or loading space in commercial development. Paved rear service streets of not less than 20 feet in width or, in lieu thereof, adequate off-street loading space, suitably surfaced, shall be provided in connection with lots designed for commercial use.
K. 
Free flow of vehicular traffic abutting commercial developments. In front of areas zoned and designed for commercial use, or where a change of zoning to a zone which permits commercial use is contemplated, the street width shall be increased by such amount on each side as may be deemed necessary by the Planning Board to assure the free flow of through traffic without interference by parked or parking vehicles and to provide adequate and safe parking space for such commercial or business district.
L. 
Curve radii at street intersections. All street right-of-way property lines at intersections shall be rounded by curves of at least twenty-foot radius and curbs shall be adjusted accordingly.
M. 
Steep grades and curves; visibility at intersections. A combination of steep grades and curves shall be avoided. In order to provide visibility for traffic safety, that portion of any corner lot (whether at an intersection entirely within the subdivision or of a new street with an existing street) which is shown shaded on Sketch A shall be cleared of all growth (except isolated trees) and obstructions above the level three feet higher than the center line of the street. If directed, ground shall be excavated to achieve visibility.
A. 
Type of name. All street names shown on a preliminary plat or subdivision plat shall be approved by the Planning Board. In general, streets shall have names and not numbers or letters.
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, except that streets that join or are in alignment with streets of an abutting or neighboring property shall bear the same name. Generally, no street should change direction by more than 90º without a change in street name.
A. 
Lots to be buildable. The lot arrangement shall be such that in constructing a building in compliance with Chapter 225, Zoning, there will be no foreseeable difficulties for reasons of topography or other natural conditions. Lots should not be of such depth as to encourage the later creation of a second building lot at the front or rear.
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 variance from this rule will give a better street or lot plan.
C. 
Corner lots. In general, corner lots should be larger than interior lots to provide for proper building setback from each street and provide a desirable building site.
D. 
Street access. All subdivisions containing more than four dwelling units shall have access onto a collector or minor street both having at least a sixty-foot right-of-way.[1]
[1]
Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. II).
E. 
Driveway access. Driveway access and grades shall conform to Village specifications. Driveway grades between the street and the setback line shall not exceed 10%.
F. 
Access from private streets. Access from private streets shall be deemed acceptable only if such streets are designed and improved in accordance with this chapter.
G. 
Monuments and lot corner markers. Permanent monuments meeting specifications approved by the Village Engineer as to size, type and installation shall be set at such block corners, angle points, points of curves in streets and other points as the Village Engineer may require, and their location shall be shown on the subdivision plat.
A. 
Removal of spring and surface water. Subdivision plans shall be related to natural drainage patterns with proper provision to be made for adequate storm drainage facilities, retention facilities, or both. The subdivider may be required by the Planning Board to carry away by pipe or open ditch any spring or surface water. Such drainage facilities shall be located in the street right-of-way where feasible or in perpetual unobstructed easements of appropriate width.
B. 
Drainage design.
(1) 
Upstream. Culverts, channels and other drainage facilities shall be large enough to accommodate potential runoff from the development as well as all future development from the entire upstream drainage area, whether inside or outside the subdivision, based on the development density permitted in the watershed. The Village Engineer shall approve the design and size of drainage facilities based on a design flow with a minimum return interval as follows:
Watershed Drainage Area
Storm Recurrence Interval
Less than 1 square mile
25-year storm
1 square mile or more
50-year storm
(2) 
Downstream. The subdivider's engineer shall also study the effect of each subdivision on the existing downstream drainage facilities outside the area of the subdivision. This study shall be reviewed by the Village Engineer. Where it is anticipated that the additional runoff incident to the development of the subdivision will overload an existing downstream drainage facility during a fifty-year storm, the Planning Board shall notify the Village Board of such potential condition. In such case, the Planning Board shall not approve the subdivision until provision has been made for the improvement of said condition.
(3) 
Storm drainage. Storm drainage facilities shall be designed to take the runoff from streets, lawns, paved areas, and roof areas. Full engineering attention shall be given to the interception and conveyance of stormwater by either the street drainage system, a system of back lot line drainage swales, main drainage channels through the subdivision, or a combination of such methods.
(4) 
Drainage runoff design criteria. While the Village reserves the right to establish particular parameters in each individual instance, the general philosophy is to permit runoff from any particular development of an amount no more than would normally occur under a natural, undeveloped condition for the particular design storm. That is, the Village generally agrees that the property owners along the downstream channel should be prepared to accept a rate of discharge from the upstream areas equivalent to the discharge from the upstream area under a natural or agricultural condition. (For undeveloped design runoff, a minimum runoff coefficient of 0.4 shall be used; see United States Soil Conservation Service, Technical Release Bulletin No. 55.)
C. 
Erosion prevention. In order to ensure that surrounding land and watercourses will not be subject to siltation or erosion, the Planning Board shall require the subdivider to follow certain erosion control practices as it deems necessary. The subdivider shall take steps to prevent erosion of topsoil and subsoil from all areas, whether inside or outside the subdivision. Such steps shall include but not be limited to:
(1) 
Provision for adequate drainage facilities to accommodate effectively the increased runoff caused by changed soil and surface conditions during and after development, including installing and maintaining temporary sedimentation basins at the point or points of stormwater discharge from the property. The subdivider's engineer shall show, as part of submitted plans, the interceptor swales and sedimentation basins along the lower edges of all developments. Significant topographic data and design grades for the swales shall be shown on the plans.
(2) 
Fitting the plan to the topography and soils so as to minimize the erosion potential in areas affected by the subdivision.
(3) 
Retention and protection of natural vegetation wherever possible.
(4) 
Seeding or sodding, or the use of anti-erosion mats or spreading straw on denuded areas.
A. 
Recreation areas shown on Village Plan. Where a proposed park, playground or open space shown on the Village Plan is located in whole or in part in a subdivision, the Board shall require that such area or areas be shown on the plat in accordance with the requirements specified in Subsection B below. Such area or areas may be dedicated to the Village or county by the subdivider if the Village Board approves such dedication.
B. 
Parks and playgrounds not shown on Village Plan.
(1) 
The Planning Board shall require that the plat show sites of a character, extent, and location suitable for the development of a park, playground, or other recreation purpose. The Planning Board may require that the developer satisfactorily grade any such recreation areas shown on the plat.
(2) 
The Board shall require that not less than three acres of recreation space be provided per 100 dwelling units shown on the plat. However, in no case shall the amount be more than 10% of the total area of the subdivision. Such area or areas may be dedicated to the Village or county by the subdivider if the Village Board approves such dedication.
C. 
Information to be submitted. In the event that an area to be used for a park or playground is required to be so shown, the subdivider shall submit, prior to final approval to the Board, three prints (one on cloth or other recordable material acceptable to the County Clerk) drawn in ink showing, at a scale of not less than 30 feet to the inch, such area and the following features thereof:
(1) 
The boundaries of said area, giving lengths and bearings of all straight lines and radii, lengths, central angles and tangent distances of all curves.
(2) 
Existing features such as brooks, ponds, clusters of trees, rock outcrops, and structures.
(3) 
Existing and, if applicable, proposed changes in grade and contours of said area and of the area immediately adjacent.
D. 
Waiver of plat designation of area for parks and playgrounds.
(1) 
In cases where the Planning Board finds that due to the size, topography, or location of the subdivision land for park, playground or other recreation purpose cannot be properly located therein or if in the opinion of the Board it is not desirable, the Board may waive the requirement that the plat show land for such purposes. The Board shall then require as a condition to approval of the plat a payment to the Village of $300 for each lot in the subdivision. The amount of land which otherwise would have been acceptable as a recreation site shall be determined in accordance with the standards set forth in Subsection B above.
(2) 
Such amount shall be paid to the Village Board at the time of final plat approval, and no plat shall be signed by the authorized officer of the Planning Board until such payment is made. All such payments shall be held by the Village Board in a special Village Recreation Site Acquisition and Improvement Fund to be used for the acquisition of land that is suitable for permanent park, playground or other recreational purposes and is so located that it will serve primarily the general neighborhood in which the land covered by the plat lies, and to be used only for park, playground or other recreational land acquisition or improvements. Such money may also be used for the physical improvement of existing parks or recreation areas serving the general neighborhood in which the land shown on the plat is situated, provided that the Planning Board finds there is a need for such improvements.
E. 
Reserve strips prohibited. Reserve strips of land which might be used to control access from the proposed subdivision to any neighboring property or to any land within the subdivision itself shall be prohibited.
F. 
Preservation of natural features. The Planning Board shall, wherever possible, establish the preservation of all natural features which add value to residential developments and to the community, such as large trees or groves, watercourses and falls, beaches, historic spots, vistas and similar irreplaceable assets.
