8.00 DESIGN STANDARDS
- Location and Alignment
- All streets in the subdivision shall be designed so that, in the opinion of the Board, they will provide safe vehicular travel. Due consideration shall also be given by the subdivider to the attractiveness of the street layout in order to obtain the maximum livability and amenity of the subdivision.
- The proposed streets shall conform to any current Master, Comprehensive or other duly adopted Town Plan, as provided in §8.02 of these Rules.
- Provision satisfactory to the Board shall be made for the proper projection of streets, or for access to adjoining property which is not yet subdivided.
- Reserve strips prohibiting access to streets or adjoining property shall not be permitted, except where, in the opinion of the Board, such strips shall be in the public interest.
- Streets entering opposite sides of another street shall be laid out either directly opposite one another, or with a minimum offset of one hundred twenty-five (125) feet between their centerlines.
- The minimum centerline radii of curved streets shall be seventy-five feet. Greater radii may be required for principal streets.
- Streets shall be laid out so as to intersect as nearly as possible at right angles. No street shall intersect another at less than sixty (60) degrees. The vertical grade of the street shall not exceed a slope of four (4) percent for a minimum distance of one hundred (100) feet from the intersection.
- Property and pavement edge-lines at street intersections shall be rounded or cut back to provide for a curb radius of at least twenty feet.
- The maximum linear grade for streets, measured at the centerline, shall be as follows: major streets, five percent; secondary streets, eight percent; and minor streets, ten percent.
- All vertical curves shall be designed to provide a minimum sight distance of 200 feet on major streets, 150 feet on secondary streets and 100 feet on minor streets, measured at three and one-half (3 1/2) feet above the pavement.
- 4. Deadend Streets
- Deadend streets shall not be longer that eight hundred (800) feet unless, in the opinion of the Board, a greater length is necessitated by topography or other local conditions.
- Deadend streets shall be provided at the closed end with a turnaround having a radius of at least fifty (50) feet, measured at the pavement edge, and a property line radius of at least sixty-five (65) feet, which line shall be used to compute street frontage.
- Temporary deadends, where further extension of the street or connection with another street is planned or projected, shall be provided with a temporary turnarounds, either “L” shaped or “hammerhead” shaped, with an inside radius of at least twenty feet and a depth of at least thirty feet from the street centerline. Temporary easements shall be provided as needed. When the street is extended or connected, the temporary easement shall be terminated, the temporary turnaround removed, and the landscape restored. Temporary turnarounds may not be used in computing street frontage to meet zoning dimensional requirements. The Town shall not release the performance bond or covenant for a development until any temporary deadend street(s) have either been extended to the proposed final length and connected to another street or the temporary turnaround has been replace with a permanent turnaround as described in §8.06 (4b). In no case shall a temporary turnaround remain in place for longer than five (5) years.
- 5. Easements
- Easements for utilities shall be at least twenty (20) feet wide.
- Where a subdivision is traversed by a water course, drainage way, channel, or stream, the subdivider shall convey to the Town of Huntington, a storm water easement or drainage right-of-way which conforms substantially to the lines of water course, drainage way, channel, or stream. Said easement shall be within boundaries which are no closer than five (5) feet, measured horizontally, from the annual high water line. In no case shall said easement have a width of less than twenty (20) feet.
- Wherever possible, easements shall be continuous from lot to lot and street to street, shall be along rear or side lot lines, and shall create a minimum number of irregularities
- 6. Curb Cuts
- Driveways shall be at least nine feet wide and have a curb return at the roadway with a three (3) foot radius.
- Where rolled curbs or no curbs exist, the driveway flare shall have a three foot radius.
- Driveway cuts shall be at least fifty (50) feet from any intersection, measured between nearest edge-lines, irrespective of radii.
- Guard Rails
- 8. Site Maintenance
- Asset Preservation; Conflicts
The minimum width of street rights-of-way shall be forty (40) feet for minor streets, forty-four (44) feet for secondary streets and forty-eight (48) feet for major streets. Greater width shall be required by the Board when deemed necessary for present or future needs. In any case, the developer will clear the right-of-way as specified in §9.02, and only to the extent necessary for the roadway, drainage, utilities, and public safety, consistent with §8.00 (Design Standards) of these Rules.
Street width shall mean the width of the top course of pavement, not including curbs, and shall be based on projected traffic volume generated by the development, using the formula of ten (10) average daily trips (ADT) per dwelling unit and the following:
|Not more than 300 ADT||Minor street:||twenty (20) foot minimum width|
|Not more than 500 ADT||Secondary street:||twenty two (22) foot minimum width|
|More than 500 ADT||Major street:||twenty four (24) foot minimum width|
Guard rails shall be provided at any hazardous points along any streets within the subdivision, including, for example, high fills or fills on sharp curves or along deep ditches. Guard rails should be of a type which does not detract from the attractiveness of its surroundings, such as Core-10 or other context-sensitive designs.
All utilities shall be installed underground at the time of initial construction.
Work sites shall be kept reasonably clear of debris at all times. Prior to the issuance of a Certificate of Occupancy of a house within a subdivision, the roadway base pavement, berms, and sidewalk base, at a minimum, shall be installed from the nearest town road, or completed subdivision street, to the farthest property line of the lot on which said house is located. During subsequent construction, paved surfaces servicing houses for which Certificates of Occupancy have been issued shall be kept free of dirt and other debris. During all phases of construction, all drainage ditches, pipes, and related structures for control of stormwater shall be kept open and clear of debris.
Upon completion of the subdivision, the subdivider shall remove all temporary structures, rubbish, and surplus materials from the area within thirty (30) days. All paved surfaces shall be swept clean and catch basins shall be cleared of any debris.
As provided in §8.04 of these Rules, due regard shall be shown for all natural features, such as topography, ridgeline features, large trees, wooded areas, water courses, scenic points, historic spots, and similar community assets which, if preserved, will add attractiveness and value to the subdivision. The Planning Board may require that it be given limited site development control in particularly sensitive areas of town, such as near the town center or on ridgelines which are visible from significant portions of the surrounding area.
Where any standards in §8.06 are in conflict with §8.04 in the context of the plan for a proposed subdivision, the Planning Board may deviate from the standards to the extent that safety of the residents of the subdivision and the Town of Huntington is not significantly compromised.
In all cases, it shall be the goal of the subdivider and the Planning Board to design a subdivision which is in harmony with the character of its immediate surroundings and the Town of Huntington.
