[Amended 11-15-2005 by L.L. No. 12-2005]
A. 
Considerations. In considering applications for subdivision of land and/or development, the Planning Board shall be guided by the standards set forth herein as the minimum requirements for the convenience, health comfort, safety and welfare of the Village. It is expressly declared that these requirements do not create a right to subdivide or partition by any party, but are merely the minimum conditions that must be met before any further consideration is due. The Board shall further consider whether the proposal is appropriate for the Village in its character and nature, in the best interests of good planning for the residents, current and future, of the Village.
B. 
Land to be subdivided and/or developed 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, without development of steep slopes and/or wetlands. Land subject to such hazards shall not be subdivided nor developed for residential purposes nor for such other uses as may increase danger to health, life or property, or aggravate a flood hazard, but such land may be set aside for such uses as shall not involve such danger nor produce unsatisfactory living conditions.
C. 
Conformance to Master Plan and Official Map. Land to be subdivided and/or developed 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, without development of steep slopes and/or wetlands except as permitted by the Village Code.
[Repealed 11-15-2005 by L.L. No. 12-2005; added 3-21-2006 by L.L. No. 5-2006]
D. 
Frontage on improved street. Notwithstanding the provisions of this section, unless street frontage is required by another provision of the Village Code, where the Planning Board affirmatively finds that the protection or preservation of the environment, open space or historic structures will be furthered, enhanced and served thereby, the Planning Board may approve a subdivision, or impose a condition thereon, which contains one or more lots which have either no, or limited, street frontage. Except where such authority is expressly conferred on the Planning Board, the Planning Board shall not have authority to grant or approve any variance of the zoning regulations of the Village.
[Amended 11-15-2005 by L.L. No. 12-2005; 3-21-2006 by L.L. No. 5-2006]
E. 
Preservation of natural cover.
(1) 
Land to be subdivided and/or developed shall be laid out and improved in reasonable conformity to existing topography, in order to minimize grading, cut and fill, and to retain, insofar as possible, the natural contours, limit stormwater runoff, and conserve the natural cover and soil. No topsoil, sand or gravel shall be removed from any lots shown on any subdivision plat except for the purpose of improving such lots and for the laying out of streets shown thereon. Topsoil so removed shall be restored to a depth of six inches and properly seeded and fertilized on the areas of such lots not occupied by buildings or structures. No excess topsoil so removed shall be disposed of outside of the boundaries of the Village except upon the approval of the Board of Trustees of the Village.
(2) 
The Board shall not approve a subdivision or partition having one or more of the following characteristics:
[Added 11-15-2005 by L.L. No. 12-2005]
(a) 
A lot comprised of 25% or more steep slopes or very steep slopes, as defined in Chapter 177, Freshwater Wetlands and Steep Slopes;
(b) 
Construction or disturbance of a steep slope area or very steep slope area; provided, however, that the Board may approve a lot or subdivision if it determines that there is no other alternative design that would permit a viable lawful residential use, and in such case the Board shall impose such conditions as are necessary to make certain that such sloped lands are protected to a reasonable extent.
F. 
Preservation of existing natural features. Existing natural features that enhance the attractiveness of the site and which would add value to residential or other development or to the Village as a whole, such as trees, watercourses, ponds and similar irreplaceable assets, shall be preserved insofar as possible by harmonious design of the subdivision. The Board may reject any proposal that fails to accomplish the goals set forth in this section, or may impose such conditions or modifications as are necessary to do so. If the subdivider finds compliance with the Board's conditions or modifications unacceptable, then the Board shall reject the proposal.
[Amended 11-15-2005 by L.L. No. 12-2005]
A. 
General. The arrangement, character, extent, width, grade and location of all streets shall conform to the Master Plan and Official Map and shall be considered in their relation to existing and planned streets, to existing topography and natural features, to public convenience and safety, and in their appropriate relation to the proposed uses of the land to be served by such streets.
B. 
Relation to topography. Street layouts and grades shall be related appropriately to the existing topography, and streets shall be arranged to obtain as many as possible of the building sites at, or above, the grades of the streets. Steep grades shall be avoided as well as combinations of steep grades and curves.
C. 
Arrangement. Where proposed streets are not shown on the Master Plan or Official Map, such streets shall be of sufficient width, suitably located, and adequately constructed, to accommodate the prospective traffic and to facilitate drainage, and to afford access for fire fighting, snow removal, and road maintenance equipment. Such streets shall be coordinated so as to compose a convenient system and to cause no undue hardship to adjoining properties.
D. 
Arrangements. The arrangement of streets shall provide for the continuation of principal streets between adjacent properties when such continuation is necessary for convenient movement of traffic, effective fire protection or efficient provision of utilities and also where such continuation is in accordance with the Master Plan. If the adjacent property is undeveloped and the street must be a dead-end street temporarily, the right-of-way shall be extended to the property line. A temporary circular turnaround shall be provided on all temporary dead-end streets, with the notation on the plat that land outside the normal street right-of-way shall revert to abuttors whenever the street is continued.
E. 
Intersections.
(1) 
Street jogs with center line offsets of less than 125 feet shall not be permitted except with the approval of the Board.
(2) 
Intersections of streets shall be at angles as close to 90° as possible. Toward this end, an oblique street should be curved approaching an intersection and should be approximately at right angles for at least 100 feet therefrom. Where three or more streets intersect, a turning circle or other special treatment may be required by the Board. Wherever two streets intersect at an angle smaller than 75%, the right-of-way returns and the relation of the gutter grades shall be given special treatment, as determined by the Board and islands to channelize traffic may be required.
(3) 
Intersections of major streets by other streets shall be at least 800 feet apart, if possible. Cross (four-cornered) street intersections shall be avoided insofar as possible, except as shown on the Master Plan or at other important traffic intersections. A distance at least equal to the minimum required lot depth plus 25 feet shall be maintained between center lines of offset intersecting streets. Grades shall be limited to no more than 2% within 50 feet of an intersection.
F. 
Treatment along major arterial streets. Where a subdivision abuts or contains an existing or proposed major arterial 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.
G. 
Provision for future resubdivision. Where a tract is subdivided into lots substantially larger than the minimum size required by the zoning, the Board may require that streets and lots be laid out so as to permit future resubdivision in accordance with the requirements contained in these regulations.
H. 
Dead-end streets.
(1) 
Where a street does not extend to the boundary of the subdivision and its continuation is not required by the Board for access to adjoining property, its terminus shall normally not be nearer to such boundary than 100 feet or the minimum lot depth prescribed by Chapter 320, Zoning, whichever is greater. However, the Board shall require the reservation of a twenty-foot wide easement to accommodate drainage facilities, pedestrian traffic or utilities.
(2) 
For greater convenience to traffic and more effective police and fire protection, permanent dead-end streets shall be limited in length to 900 feet and shall be provided at the closed end with a turnaround having an outside roadway diameter of at least 80 feet, and a street property line diameter of at least 100 feet. In zoning districts, however, which permit lots of less than one acre, the minimum outside roadway diameter shall be increased to 100 feet and the diameter at the property line be increased to 120 feet. Where it is impossible to subdivide a property except by a dead-end road which is longer than 900 feet, the Board may permit a greater length, provided that a divided roadway with center mall is constructed in a 70 feet right-of-way (or greater width, if required) in such a manner that either side of the roadway could be used, in emergencies, for two-way traffic.
I. 
Design standards for streets. Streets shall meet the design standards set forth below. In cases where street classification is not shown on the Master Plan or Official Map, the Board shall determine the type of each street, standards do not cover major streets which would be built by the state or county.
A. 
Generally for streets not shown on the Master Plan, the width shall be not less than:
(1) 
Local street: 50 feet.
(2) 
Secondary street: 60 feet.
(3) 
Major street: 80 feet.
(4) 
Marginal access street: 40 feet.
B. 
Grades.
(1) 
Grades of all streets shall be the reasonable minimum and unless warranted by extenuating circumstances, shall be:
(a) 
Local and marginal streets: not less than 1.0% or more than 8%;
(b) 
Secondary and Major streets: not less than 1.0% or more than 5%.
(2) 
Gradients shall be used to facilitate surface drainage to proper natural or artificial outlets.
C. 
Changes in grade. All changes in street grades shall be connected by vertical curves of sufficient radius to provide a smooth transition and proper sight distance, as approved by the Board.
D. 
Tangents. A tangent at least 100 feet in length shall be introduced between reverse curves on all streets, except where a greater length is required by the Board.
E. 
Curves. When the alignment of the street changes more than 10°, the tangents shall be connected by a curve with a radius of not less than 200 feet, unless a greater radius is required by the Board to ensure a proper sight distance.
Reserve strips controlling access to streets shall be prohibited except where their control is placed in the Village under conditions approved by the Board.
Property lines at intersections shall be established in such a manner as to place within the street right-of-way the triangular area which is formed by the street lines extended and a straight line adjoining points on said street lines 30 feet distant from their point of intersection.
A. 
All streets shall be named, and such names shall be approved by the Board. Names shall be sufficiently different in sound and in spelling from other street names in the Village or adjoining municipalities so as not to cause confusion. A street which is a continuation of an existing street shall bear the same name.
B. 
In general, street names shall conform to the following classifications:
(1) 
Road: major or secondary street.
(2) 
Drive or lane: local residential street, except as follows:
(a) 
Court or place: permanent dead-end street.
(b) 
Circle: Street that returns to its starting point, or a street, both ends of which intersect another street at different locations.
A. 
Utilities. Easements across lots or centered on rear or side lot lines shall be provided for utilities where necessary and shall be at least 20 feet wide.
B. 
Drainageway. Where a subdivision is traversed by a watercourse, channel or drainageway, as defined herein, there shall be provided a stormwater easement or drainage right-of-way conforming substantially with the lines of such watercourse, and such further width or construction, or both, as will be adequate for the purpose. The Board may require parallel streets or parkways in connection with such drainageway.
A. 
Length; width; shape. The length, width and shape of a block shall be determined with due regard to:
(1) 
Provision of adequate building sites suitable to the special needs of the type of use contemplated.
(2) 
Zoning requirements as to lot sizes and dimensions.
(3) 
Needs for convenient access, circulation, control and safety of street traffic.
(4) 
Limitations and opportunities of topography, and the objectives of these regulations.
B. 
Dimensions. Block dimensions shall be at least twice the minimum lot depth and generally not more than 1,200 feet.
C. 
Crosswalk. In long blocks the Board may require the establishment of easements or public ways through the block to accommodate utilities, drainage facilities, or pedestrian access to community facilities.
A. 
General. The lot size, width, depth, shape, and orientation, and the minimum building setback lines shall be appropriate for the location of the subdivision and for the type of development and use contemplated.
B. 
Dimensions and corner lots. Lot area and dimensions shall conform to the requirements of Chapter 320, Zoning, and Health Department regulations. Corner lots for residential use shall have extra width to permit compliance with the front yard setback from both streets. Where lots are more than double the minimum area required by Chapter 320, Zoning, the Board may require that such lots shall be of such dimensions and arrangement as will allow further subdivision and the opening of future streets where necessary to serve potential lots all in compliance with Chapter 320 and these regulations. Generally the depth of a lot shall not exceed two and 1/2 times the width.
C. 
Arrangement and access. The lot arrangement shall be such that there will be no foreseeable difficulty, for reasons of topography or other conditions, in obtaining building permits to build on all lots in compliance with applicable regulations; and in providing, by means of a street approved by the Board and upon which each lot fronts, safe driveway access to buildings on such lots from an improved street duly placed on the Official Map.
D. 
Access across a watercourse. Where a watercourse separates the buildable area of a lot from the street by which it has access, provisions shall be made for installation of a culvert or other structure, of design approved by the Engineer.
E. 
Lot lines and setbacks. Side lot lines shall be substantially at right angles to straight streets, and radial to curved street lines. Lot lines shall coincide with municipal boundary lines rather than cross them. Where extra width has been dedicated for widening an existing street, lots shall begin at such extra width line, and lot dimensions and setbacks shall be measured from such line. The Board may, whenever it deems such lines desirable or necessary, require the showing on the plat of specific setback lines which may vary from lot to lot provided the front setback shall be not less than the zoning requirement, nor more than 20% greater than the zoning setback.
F. 
Double frontage. Double frontage lots other than corner lots, shall be avoided except where deemed essential by the Board in order to provide separation of residential development from traffic arteries or to overcome specific disadvantages of topography and orientation. An easement, or reserve strip, at least 20 feet in width and across which there shall be no right of access, shall be provided along the line of lots abutting such traffic artery or other disadvantageous use and such easement shall be planted and maintained as may be approved by the Board.
