A subdivider who proposes to develop a subdivision in the Town of Rhinebeck shall observe all general requirements for land subdivision as herein provided.
A. 
Character of land. Land to be subdivided shall be of such character that, in the opinion of the Planning Board, it can be used safely for building purposes without danger to health or peril from fire, flood or other menace and with a minimum of detrimental effects on the environment.
B. 
Preservation of existing features. The Planning Board may require, in subdivision design and through the subsequent dedication of conservation easements, the preservation of natural and cultural features which add value to residential developments and to the community, such as active farmland, large trees or forested areas, water resources, beaches, historic structures and features, scenic views, ridgelines, steep slopes, rock outcrops, stone walls, hedgerows, biodiversity and wildlife habitats, and similar irreplaceable assets.
C. 
Conformance with Zoning Law and Comprehensive Plan. Subdivision plats and improvements provided shall conform to the Zoning Law[1] and Freshwater Wetlands Law[2] of the Town of Rhinebeck and shall be in harmony with the Town Comprehensive Plan, including the Significant Habitats Report and the Open Space and Affordable Housing Implementation Plan, the Dutchess County Plan: Directions, and the Greenway Compact Program Guidelines: Greenway Connections. In addition, as an extension of the Town Comprehensive Plan, the subdivision plat shall be consistent with the intent, purposes and objectives of the environmental and cultural protection programs which may be applicable to the proposed subdivision location. These programs include the Town's Local Waterfront Revitalization Program,[3] the Mid-Hudson Historic Shorelands Scenic District Management Plan, scenic roads (including the Hudson Valley Scenic Roads Masterplan) and scenic byways programs, scenic areas of statewide significance, National Historic Landmark District, National and State Registers of Historic Places sites and districts and any locally or state-designated critical environmental areas (CEAs).

Editor's Note: See Ch. 119, Waterfront Revitalization Program.
D. 
Minimum dimensional standards. No lot in a conventional subdivision shall have less than the minimum lot area and minimum lot dimension required by the Zoning Law for the district in which it is located, unless otherwise provided in the Zoning Law.[4] No lot in a conservation subdivision shall have less than the minimum dimensional standards and minimum open space required by Article V, § 125-43, of the Zoning Law for the district in which it is located. The Planning Board may impose higher planning and design standards than otherwise provided for lots in a conventional subdivision, including yield subdivision plans prepared for the purposes of determining density in conservation subdivisions, when there exists good reason in the nature of the land, including but not limited to topography, location, shape, size, drainage, surface water and groundwater resources, and other physical features of the site as well as the character of the surrounding community.
[4]
Editor's Note: See Ch. 125, Zoning, including the Schedule of Area and Bulk Regulations included at the end thereof.
E. 
Plats with access through other municipalities. Whenever access to a subdivision is by crossing land in another municipality, the Planning Board may require assurance from said municipality that such access is adequately improved or that a legally adequate performance guarantee has been duly posted and is sufficient in amount to assure the construction of the necessary road or roads.
F. 
Resubdivision. Resubdivision of all or part of land covered by an existing plat which has been laid out prior to the compulsory subdivision plat review, approval and filing shall comply with these regulations as now required.
G. 
Preservation of topsoil. No topsoil shall be removed from any subdivision in the Town, except that in areas over which heavy equipment will be operated, the topsoil shall be stripped and stockpiled on the property. When final grades have been established and construction activities have been completed, the entire property shall be suitably graded and, to the extent practicable, recovered with topsoil, except that portion of the site covered by buildings or included in the roads.
H. 
Watercourses. Where a watercourse separates a proposed street from an abutting property, provision shall be made for access to all lots by culverts, bridges or other permanent structures, provided such structures minimize adverse impacts on water resources. Such structures shall be designed to accommodate access by construction, emergency, fuel and other large vehicles and should have an unobstructed width of 12 feet and the ability to support 65,000 pounds. Where a subdivision is traversed by a watercourse, drainageway, channel, or stream, there shall be provided a stormwater easement or drainage right-of-way, not less than 30 feet in width. All such structures and rights-of-way shall be of design and specification approved by the designated Town Engineer and the Town Highway Superintendent, in consultation with the Town's Conservation Advisory Council.
I. 
Floodplains. If any portion of the land within the subdivision is subject to periodic inundation or flood hazard caused by stormwater, this portion shall be clearly indicated on any submissions required by these regulations. In cases of doubt, the Planning Board may require the submission of a flood hazard study delineating the limits of the one-hundred-year floodplain. Such study shall be conducted by the applicant's licensed professional engineer.
(1) 
Land subject to flooding, and land deemed by the Planning Board to be otherwise uninhabitable, shall not be platted for residential or commercial occupancy or for any such other use that may increase danger to life, health, or property or aggravate the flood hazard.
(2) 
Any subdivision, including all proposed improvements and construction, shall comply with all further applicable provisions of the National Flood Insurance Act of 1968, including all amendments thereto, with the Town of Rhinebeck Flood Damage Prevention Law,[5] and with the Town of Rhinebeck Flood Fringe Overlay District regulations found at Article V, § 125-41, of the Zoning Law. In the event of a conflict, the more stringent regulation shall apply.
[5]
Editor's Note: See Ch. 73, Flood Damage Prevention.
The subdivider shall additionally conform to all subdivision design standards as herein provided. These standards shall be considered minimum standards and shall be modified, or waived, by the Planning Board only as provided for in Article X of these regulations. In addition to the design standards, Appendix B of these Subdivision Regulations contains illustrated subdivision and house siting design guidelines to be consulted for the design and siting of all uses in all zoning districts.[1]
A. 
Lots.
(1) 
Lots to be buildable. The lot arrangement shall be such that construction of a building and related improvements is in compliance with the Zoning Law[2] and there will be no foreseeable prohibitions to development based upon soils, topography or other natural conditions, including the presence of wetlands or floodplain areas.
[2]
Editor's Note: See Ch. 125, Zoning.
(2) 
Corner lots. Corner lots shall be of sufficient dimensions so that any structure placed thereon shall conform to the building setback line on both streets, as well as side yard requirements, for the zoning district in which the lot is located.
(3) 
Minimum lot size. Except as provided by Article VIII of these regulations for conservation subdivisions, each lot shall be no smaller than the minimum lot area, lot frontage and lot width required by the Zoning Law[3] for the district in which it is located, including the provision that no less than three-fourths (75%) of the minimum lot area within any zoning district must be fulfilled by land which is outside any regulated wetland, water body, or a FEMA-designated one-hundred-year floodplain.
[3]
Editor's Note: See Ch. 125, Zoning.
(4) 
Driveway grade and design. Driveway grades between the street pavement and the required building setback line shall not exceed 10%, with suitable negative grade provided within 20 feet of the intersecting street pavement. The remainder of the driveway shall be designed and built to afford suitable access to the building site in accordance with the provisions of the New York State Uniform Fire Prevention and Building Code, with any design guidelines or standards which may be adopted by the Town Board, and to prevent adverse impacts from either stormwater drainage or erosion on the public street or roadway.
(5) 
Access from public streets.
(a) 
The subdividing of land shall be such as to provide each lot with satisfactory access for routine and emergency purposes from the community's system of streets. This access may be provided either directly or, in the case of an approved conservation subdivision or conservation density subdivision, by suitably improved and maintained private streets, which the Planning Board is authorized to approve.
(b) 
A lot with frontage of less than 300 feet fronting on a county or state highway shall be designed so as to share a common curb cut with any adjacent lot, if either adjacent lot has not been previously granted a curb cut permit. When more than three lots are proposed to be subdivided from a parcel with frontage on a county or state highway, frontage for all such lots shall be on an internal street, not on the county or state highway. Each lot permitted to front on a county or state highway shall provide for an improved on-site turnaround so as to obviate the necessity of any vehicle backing onto such highways. Similar provision for on-site turnarounds on Town highways shall be encouraged. Any such common curb cut and/or common driveway shall be subject to reciprocal easements and suitable maintenance agreements, which shall be reviewed and approved by the Planning Board and filed in the County Clerk's office.
(6) 
Access from private streets. Access from privately owned and maintained streets, as may be specifically authorized in accordance with § 280-a of Town Law, shall be deemed acceptable only if such streets are designed and improved in accordance with Article V, § 101-5.2B, of these regulations, and means satisfactory to the Planning Board are provided for the long-term ownership and maintenance of said privately owned and maintained streets.
B. 
Streets.
(1) 
General objectives. Streets shall be of sufficient width for their intended purposes, suitably located, and adequately constructed to accommodate the prospective traffic, both vehicular and pedestrian, and normal road maintenance equipment. The arrangement of streets shall be coordinated such that they compose a convenient system, cause no undue hardship to adjoining properties, are consistent with and avoid or minimize adverse impacts upon any adopted critical environmental area (CEA) designations under SEQR, and render no property inaccessible from an existing street or from a proposed street in a subdivision for which a completion bond or similar performance guarantee has been posted.
(2) 
Relation to topography. Streets shall be logically related and conform insofar as possible to the original topography. They shall be arranged so as to obtain as many as possible of the building sites at or above the grades of the streets. A combination of steep grades and sharp curves shall be avoided.
(3) 
Arrangement of streets. To the extent practicable, 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, by use of stub streets, in order to make possible necessary fire protection, movement of traffic and pedestrians and the construction or extension, presently or when later required, of needed utilities and services. Any stub street or other intended through street shall be provided with a temporary turnaround with a pavement radius of at least 40 feet. A note on the subdivision plat shall state that the land included within the turnaround which is outside the normal street right-of-way shall revert to abutters upon continuation of the stub street and shall be regraded and seeded.
(4) 
Street connections. Subdivisions containing 12 or more lots shall have at least two connections with existing public streets, with streets shown on the Town's Official Map as may be developed in accordance with § 270 of the Town Law, or streets shown on an approved subdivision plat for which a performance bond or similar performance guarantee has been posted.
(5) 
Cul-de-sac streets. Cul-de-sac streets shall not be created to provide access to residential lots except in situations where, in the view of the Planning Board, a through street cannot reasonably be provided due to the physical characteristics of the subdivision parcel and adjoining properties. Where a cul-de-sac street is authorized, either as a permanent dead-end street or as a temporary dead-end street pending completion of the through road network, not more than 12 single-family residential lots may gain access from such cul-de-sac street.
(a) 
A cul-de-sac street shall be restricted to a maximum grade of 7% and to a length of 2,000 feet in the HP20 Zoning District, 1,500 feet in the RA10 Zoning District, and 1,000 feet in the other zoning districts.
(b) 
A turnaround with a right-of-way radius of at least 60 feet and a pavement radius of at least 40 feet, with an island in the center, shall be provided at the end of any cul-de-sac or permanent dead-end street as illustrated in the graphic.[4] The cul-de-sac street shall otherwise be governed by all stated requirements of the Town's highway specifications.
[4]
Editor's Note: See the graphic following Subsection B(8)(b) below.
(6) 
Private streets. The Planning Board may approve paved or unpaved private roads to provide access to lots in conservation subdivisions and conservation density subdivisions, provided that the Planning Board finds that the proposed subdivision will protect the rural, scenic and natural character of the Town. The private road requirements are as follows:
(a) 
The maximum number of lots gaining access through any portion of a private road shall be 10.
(b) 
Written approval from the Town Engineer shall be secured before approval of any private road. The Town Superintendent of Highways shall approve the intersection of the private road with any Town road. Any required permit for the intersection of a private road with a state or county highway shall be the sole responsibility of the applicant.
(c) 
A homeowners' association (HOA) must be created to own and provide for the perpetual care and maintenance of the private road. The Planning Board shall have discretion to determine whether a performance bond must be posted by the applicant to ensure the proper completion of the private road and, if so, how much the performance bond shall be and what form it shall take.
(d) 
Such HOA must have the power to assess the subdivision lot owners for their share of the maintenance costs of the private road. The HOA shall ensure that the road will always be maintained and kept open to permit emergency vehicle access.
(e) 
In the event the HOA does not ensure that the road is properly maintained, the Town of Rhinebeck may assume maintenance responsibilities and charge the HOA for all reasonable costs thereof. Such costs, if unpaid for more than 60 days, shall, along with attorneys' fees for their collection, become a lien on the property and enforceable in the same manner as a property tax lien.
(f) 
The private road can only be offered for dedication to the Town of Rhinebeck if it conforms to the Town highway specifications in effect on the date of the offer of dedication. However, the Town Board shall be under no obligation to accept such an offer of dedication, even if the road conforms to Town highway specifications. In the event such dedication becomes necessary to ensure public safety, the cost of bringing the road up to Town highway specifications shall be fully borne by the HOA.
(g) 
The subdivision plat shall show the road clearly labeled "private road."
(h) 
Road design shall comply with the standards for private roads in these Subdivision Regulations.
(i) 
When a private road is approved, the subdivider shall establish a road maintenance endowment fund, of a sum to be specified by the Planning Board, to ensure the proper long-term maintenance of the road(s). This fund shall be administered by the HOA, with the Town Board named as a third-party enforcing agent, and shall be used for road reconstruction and its supporting engineering review and inspection. The Planning Board shall devise a maintenance schedule prior to approval, and this schedule shall be incorporated into the documents creating the fund.
(j) 
The Planning Board may waive the requirement of a private road maintained by a HOA if it finds, after consulting with the attorney for the Planning Board or the Town Attorney, that a common drive providing access to a maximum of four dwelling units, maintained pursuant to a recorded maintenance agreement, executed by the applicant as a condition of subdivision approval, will provide the same protections to lot owners and the Town as would a private road owned by an HOA. Issuance of a "no action" letter from the New York State Attorney General's Office shall be a condition of such waiver.
(7) 
Common driveways. Common driveways will be permitted in the Town of Rhinebeck in accordance with the following specifications, in addition to any design guidelines or standards which may be adopted by the Town Board. The common driveway is defined as that portion of the driveway that provides access to two or more individual parcels. The common driveway becomes a private access at the point at which it provides access to one parcel. A plan and profile for the common driveway shall be prepared by a licensed professional engineer and submitted for approval by the Planning Board.
(a) 
Number of lots. A maximum of four lots can be served by one common driveway.
(b) 
Length. The common portion of the driveway shall not exceed 1,200 feet in length. The individual private extensions leading from the common driveway are not restricted by this section.
(c) 
Design. Common driveways shall be designed and built in accordance with the approved subdivision plan to allow for the passage of all vehicles expected to use the driveway year round.
(d) 
The traveled way shall be a minimum width of 12 feet with two-foot shoulders on each side.
(e) 
Maximum grade shall be 12% and minimum grade shall be 0.5%. Grades at intersecting roadways shall not exceed 3% for the first 30 feet from the sidelines of the intersecting edge of pavement.
(f) 
The driveway may be gravel or paved. A minimum gravel base of 12 inches, with no aggregate larger than six inches, shall be required. An additional two-inch wearing surface shall be dense, graded, crushed stone for all common driveways.
(g) 
The driveway shall be paved 15 feet from the edge of existing pavement or to the property line, whichever distance is lesser, unless other specifications are approved by the Planning Board.
(h) 
Culverts or water crossings shall comply with the Town highway specifications.
(i) 
Common driveway identification. A permanent marker, meeting the specifications of the Planning Board and the Dutchess County 911 addressing system, shall be placed at the end of the driveway where it meets the street. The marker shall show all 911 locations and street numbers. Should the common driveway split, permanent markers shall also be placed at the intersections indicating which homes are located on either side of the split. Lettering shall have a minimum size of four inches and shall be painted black or another contrasting color or shall be permanently etched in the marker.
(j) 
Bond. The common driveway shall meet the Subdivision Regulations' bonding requirements.
(k) 
Inspections. The common drive shall be inspected by the Town Engineer to ensure the use of the required materials and proper construction. Funds for these inspections shall be escrowed as set forth in the Subdivision Fee Schedule and Article XIV of the Zoning Law.[5]
[5]
Editor's Note: See Ch. 125, Zoning.
(l) 
Building permits and certificates of occupancy. The common driveway shall be complete up to a point 15 feet beyond the common access point, between the dwelling and the Town road, including drainage, crushed gravel and grading, and all identification markers shall be installed prior to the issuance of a building permit.
(8) 
Minimum design standards.
(a) 
Streets and related improvements shall be designed to reflect the rural, scenic and agricultural character of the Town of Rhinebeck. Where approval is sought for a subdivision on land of a rural, scenic, environmentally sensitive or agricultural nature, the Planning Board is empowered to and may, in consultation with the Town Highway Superintendent and designated Town Engineer, waive strict compliance with the requirements of the Town Street and Highway Specifications in order to allow roads more in keeping with the character of the rural landscape. In such cases, the Board will consider the following factors before approving a deviation from the Town Street and Highway Specifications requirements:
[1] 
Zoning district and density of land use.
[2] 
Number of lots and probable traffic volume generated by the proposed subdivision.
[3] 
Projected future development likely to use the road.
[4] 
Other public uses of the road (e.g., farm or recreational access).
[5] 
Road length.
[6] 
Design of the road and of the development with respect to preservation of open space, scenic resources, and other conservation measures.
(b) 
The following design guidelines and standards shall apply to rural roads:

A 50-foot right-of-way is required by State Highway Law, but grading and clearing within the right-of-way should be reduced to the minimum necessary.
Note: Standards are not given for arterial streets, as they would in all probability be built by the state or county.
101 Cul-de-sac with Offset Island.tif
(c) 
Residential collector road. A residential collector road collects traffic from residential areas and channels it to larger roads, such as county and state highways. These roads are designed for a speed of 30 miles per hour to 35 miles per hour. It is well-traveled and accommodates a variety of vehicles, including large delivery trucks, school buses, pick-up trucks, vans, and cars. Average annual daily traffic (AADT) ranges from 50 trips to 400 trips. Bicycle lanes and sidewalks or trails are separated from the road by at least a six-foot grassy aisle.
101 Residential Collector Road.tif
(d) 
Residential and farm access road. A residential and farm access road provides access to farms and residential areas and is primarily traveled by cars, small trucks, and farm vehicles and is shared with pedestrians and bicyclists. AADT is generally 50 trips to 200 trips. These roads are designed for a speed of 25 miles per hour to 30 miles per hour. Traffic on this road is fairly light, but it may include occasional school buses and large trucks, such as milk trucks and farm equipment.
101 Res and Farm Access Road.tif
(e) 
Private road. A private road, which may be unpaved, serves a limited number of single-family residences or a recreational area. Pedestrians and bicyclists share the road with vehicles. Private roads are designed for a speed of 15 miles per hour to 25 miles per hour. Private roads are maintained by homeowners' associations or through common use and maintenance agreements, approved by the Planning Board and Town Attorney.
101 Private Road.tif
C. 
Bicycle paths and sidewalks. The Planning Board shall consider the design of bicycle paths in the subdivision, and if required, such paths shall be designed to maximize the safety of path users, shall be a minimum width of six feet, should be constructed of bituminous concrete over a gravel foundation, and shall be constructed as necessary to connect the proposed subdivision with the Town's network of trails and bicycle paths. The Planning Board shall consider the design of sidewalks in the subdivision, and if deemed appropriate and required by the Planning Board, such sidewalks shall be a minimum width of five feet, shall be constructed of concrete to ADA standards and shall connect the proposed subdivision with the Town's network of trails and bicycle paths. Shared paths accommodating both bicyclists and pedestrians are also desirable as illustrated below.
101 Bicycle Paths and Sidewalks.tif
D. 
Parks and public open space. Adequate lands for parks and other public open space purposes shall be provided in any subdivision of land for residential purposes throughout the Town of Rhinebeck.
(1) 
Amount of land dedicated. In general, the Planning Board shall require that 10% of the total land area within the subdivision be set aside and shown on the plat for park and public open space purposes, including trails and other linkages between neighborhoods. All lands designated on the plat as park or public open space must be deemed suitable for this purpose by the Planning Board based upon overall consistency with the Town Comprehensive Plan and a site-specific analysis of the lands' topographic, geologic, hydrological and locational characteristics. The Planning Board may establish such conditions on the subdivision concerning access, use, and maintenance of such park and public open space lands as deemed necessary to ensure the preservation of the lands, in perpetuity, for their intended purposes. Such conditions shall be clearly noted by the licensed land surveyor and/or professional engineer on the plat prior to final plat approval and subsequent recording of the plat in the Office of the Dutchess County Clerk.
(2) 
Information to be submitted. In the event that an area to be used for park or public open space is required to be shown, the subdivider shall submit, prior to final plat approval, to the Clerk of the Planning Board, drawings of such area at a scale of not less than 20 feet to the inch and showing the following features thereof:
(a) 
The boundaries of the area, giving lengths and bearings of all straight lines; and radii, lengths, central angles and tangent distances of all curves.
(b) 
Existing features such as streams, ponds, clusters of trees, rock outcrops and structures, existing and proposed.
(c) 
Existing and, if applicable, proposed changes in grade contours of the area and of the area immediately adjacent, for a distance of not less than 100 feet, with such contours to be at an interval of not more than two feet.
(d) 
Plans for improvements of said area, not limited to grading, seeding, fencing, landscaping, the provision of play and related equipment, and addressing conditions relating to the protection of the public health and safety.
(3) 
Payment in lieu of dedication. In cases where, because of the size, topography, or location of the subdivision, or because of the size of the individual lots provided within the subdivision or of the proposed open space, the requirements for land dedication or reservation for parks and other public open space, the Planning Board shall alternatively require, under § 277 of the Town Law, that a payment be made into a special fund for Town recreation site acquisition and/or improvement in lieu of such land dedication or reservation within the subdivision. Such payment shall be a condition of approval of the final plat and shall be assessed on a per-lot or per-dwelling-unit basis in accordance with the Subdivision Fee Schedule established and annually reviewed by the Town Board upon recommendation of the Planning Board. Such fee shall be imposed only after the Planning Board has made a finding that a proper case exists for requiring that park or recreational facilities are needed by the subdivision's residents for recreational purposes. The Planning Board, in making such findings, shall evaluate present and anticipated future needs for park and recreational facilities, based upon the cumulative demands of all recently approved and pending subdivision applications on Town recreational facilities and the resulting need to expand recreational facilities in the near future as a result of the proposed subdivision and other subdivisions and may rely on the projections and other analysis of need in the Recreational Needs Assessment for the Rhinebeck Community dated September 12, 2006, as updated from time to time. This fee shall not apply to any proposed lot presently developed with a residential structure and legally occupied within the past 12 months for residential purposes. No final plat shall be signed by the Chair of the Planning Board until such payment has been received by the Town Clerk and receipt therefor provided to the Clerk of the Planning Board.
E. 
Public improvements and utilities.
(1) 
Placement. Underground improvements required by the Planning Board in accordance with Article V, § 101-5.1, and public franchise utilities shall be placed in the street right-of-way between the street paving and the right-of-way line. Where topography makes such placement impracticable, perpetual unobstructed easements at least 20 feet in width shall be provided for along lot frontages abutting the street lines, with satisfactory access to the street. Wherever possible, easements shall be continuous from block to block and their layout shall be as regular as possible. Subject to the discretion of the Town Board, an underground public improvement or utility operated for revenue by the Town or by a special district may be installed by the Town in a private street, provided a public easement of satisfactory size is obtained for such improvement or utility. Before the street is paved, the subdivider shall install underground service connections for all required improvements and utilities to the property line of each lot within the subdivision.
(2) 
Service connections.
(a) 
Water. Where an appropriate community water main already exists and is physically and legally accessible, the subdivider may connect into said main and provide a water connection for each lot in accordance with Article 12 of the Town Law, the Public Health Law, and other applicable laws, rules and regulations. Where an appropriate water main does not exist or is not accessible, the subdivider shall install at his or her own expense such main, together with all necessary valves, cutoffs, fire hydrants, pumps, storage tanks, meters and other equipment necessary to make such water system conform to the standards of the Town.
(b) 
Sewage disposal. Where an appropriate community sanitary sewer system is reasonably accessible physically and legally, the subdivider shall install at his or her expense the necessary connections into the system and provide a sewer connection for each lot. The Planning Board may require shared or community sanitary sewage disposal systems for conservation subdivisions, where single-family attached dwellings or small hamlet-sized lots are proposed. Shared or community sanitary sewage disposal systems are encouraged for all other conservation subdivisions except for large farm or conservancy lots.
(c) 
Stormwater management system. The subdivider shall install all necessary stormwater management facilities at his or her expense, in accordance with the standards of the Town and of all authorities having jurisdiction. Where an appropriate stormwater management system is reasonably accessible, the subdivider shall make proper connection thereto.
[1] 
Otherwise, the subdivider shall provide means and methods for stormwater management satisfactory to the Planning Board and all other utilities having jurisdiction. In either event, the stormwater management facilities provided shall be fully consistent with the stormwater management design standards which may be promulgated and from time to time reviewed and modified by the Planning Board and the State of New York. The stormwater management system shall be large enough to accommodate potential runoff from the entire upstream drainage area, whether inside or outside of the subdivision. The designated Town Engineer shall approve the design and size of facilities based on anticipated runoff from at least the twenty-five-year storm under conditions of total potential development permitted by the Zoning Law[6] in the watershed. The cost of a culvert or other drainage facility in excess of that required for the particular subdivision may be deemed to be the responsibility of the Town, or may be pro rated among the upstream property owners.
[6]
Editor's Note: See Ch. 125, Zoning.
[2] 
The subdivider's engineer shall also study and report on the effect of each subdivision on the existing downstream drainage system outside the area of the subdivision; and this report shall be reviewed by the designated Town Engineer. When it is anticipated that the additional runoff incident to the development of the subdivision will overload an existing downstream drainage facility during a twenty-five-year storm, the Planning Board shall notify the Town Board of such potential condition. In such case, the Planning Board shall not approve the plat until provision has been made for the improvement of said condition.
F. 
Realignment or widening of existing streets. Where the subdivision borders an existing street proposed for realignment or widening, the Planning Board may require that land be reserved on the subdivision plat to permit the proposed improvement to be carried out. Similarly, the Planning Board shall require in its review of any subdivision plat abutting a user/roadway, as defined under § 189 of the Highway Law, the reservation of 24 3/4 feet from the center line of such user roadway for highway purposes and recommend Town Board acceptance of such land when offered for dedication by the subdivider.
G. 
Pedestrian and bicycle ways.
(1) 
Adequate provision shall be made for convenient and safe movement of pedestrians and bicyclists in any subdivision of land for residential purposes throughout the Town of Rhinebeck. All streets designated as collector roads shall have an improved pedestrian path, sidewalk, bikeway or bike path provided on at least one side of the street. Any such sidewalk or pedestrian path shall be so placed that there will be a distance of not less than six feet between the sidewalk and the street pavement. A bikeway, or combined bicyclist/pedestrian path, not less than six feet in width, may be alternatively situated adjacent to the street pavement and be visually separated therefrom by striping on both its inner and outer edges.
(2) 
To the extent considered practicable by the Planning Board, and in consideration of public health, safety and general welfare, the Planning Board may require that additional or alternatively located pedestrian and bicycle ways be provided within a residential subdivision to provide access to parks or public spaces, school sites, neighborhood shopping facilities, or similar destinations. Any such pedestrian or bicycle way may be situated within either a public right-of-way or established within a suitable easement.
H. 
Private water supply and sewage disposal facilities.
(1) 
Where community water supply and/or sewage disposal facilities are not available, the Planning Board shall ascertain as a part of subdivision plat review and approval that each prospective lot and dwelling unit may be adequately served by acceptable water supply and sewage disposal facilities, including shared or community septic disposal facilities, and ensure that all such on-site water supply and sewage disposal facilities shall be designed and installed in accordance with the requirements of the Dutchess County Health Department.
(2) 
To the extent authorized by the Public Health Law and the Dutchess County Health Department, the Planning Board may, in accordance with Article X of these regulations, waive this requirement for proposed lots in excess of five acres and instead accept a note on the plat advising of applicable Health Department permit requirements which must be met prior to the issuance of a building permit by the Town of Rhinebeck. No waiver shall be granted unless an examination of soil conditions and percolation and deep tests have been conducted by a licensed professional engineer and written certification is provided to the Planning Board that an on-site system(s), complemented by an appropriate water supply system, can be designed to serve not less than a three bedroom dwelling in accordance with Dutchess County Health Department requirements and design standards.
I. 
Street trees. Trees shall be planted on both sides of a newly installed street, in locations approved by the Planning Board, except where unnecessary due to the presence of significant, preservable existing vegetation, which shall be identified on the subdivision plat. Street trees shall generally:
(1) 
Be located near the property line, in a manner that will not obstruct sight distance nor impede street maintenance, and be spaced approximately 30 feet to 40 feet apart, subject to variations made necessary by driveways and street corners as well as by the species of trees planted;
(2) 
Have a caliper of three inches or larger measured at breast height and be not less than 10 feet in overall height at the time of planting; and
(3) 
Be approved as to species by the Planning Board, in consultation with the Conservation Advisory Council.
J. 
Maximum development envelopes and conservation areas on lots. The Planning Board shall consider, as part of subdivision plat review and approval, the required depiction of a maximum development envelope within any proposed residential building lot for the purposes of protecting and otherwise mitigating potential adverse impacts on significant environmental features, including but not limited to wetlands, wetland buffers, and stream corridors, historic and archaeological sites, scenic and other visual resources, mature woodlands and wildlife habitat, and maintaining natural buffers, whether of landform or vegetation, between individual residential building sites, two or more subdivisions, either public or private streets and roadways, or adjacent nonresidential land uses.
(1) 
Any such maximum development envelope shall encompass the land area occupied by the residential building, driveway access thereto, and supporting improvements, including water supply and sanitary sewage facilities, stormwater improvements and franchise utilities, and shall further provide reasonable land area for lawn and accessory structures. The maximum development envelope might otherwise be cited as a "maximum disturbance area."
(2) 
The remainder of the lot shall be considered a private conservation area subject to a conservation easement, covenant or other restriction, approved by the Planning Board and recorded in the Dutchess County Clerk's office simultaneously with the filing of the approved subdivision plat. The conservation easement or other restriction shall typically prohibit the construction of any residential accessory structures or related improvements within the conservation area except as may be specifically set out therein and either prohibit or otherwise restrict clearing, grading, and removal of vegetation.
