Improvement standards

A. Streets and appropriate drainage facilities within a residential compound shall be designed and constructed in compliance with this section. The Planning Board shall have the authority to require additional improvements in order to protect the public health, safety and welfare, if warranted by the characteristics of the parcel, or if the street will be used by persons other than residents of the compound.
B. Private rights-of-way within a residential compound shall meet the following design standards:
- (1) A right-of-way intersect width at the existing public road or private right-of-way of at least 30 feet, for a distance of 50 feet.
- (2) A paved staging area of at least 50 feet in length from the edge of pavement of the street it intersects with, with a minimum width of 20 feet of pavement, and sloped not more than 4% grade for the 50 feet it extends from the street line.
- (3) Where possible, a compound street center line angle intersection with the street center line of 90° (perpendicular with the existing road).
- (4) Pavement for the staging area, and any proposed or existing grading beyond the staging area of greater than 6%, shall be paved in accordance with road construction standards in Chapter 450, Land Development and Subdivision Regulations, Article XIV, § 450-62.
- (5) A wear surface, on that portion of the private right-of-way extending beyond the staging area, of a minimum of 12 inches of graded gravel, placed over a properly prepared base, graded and compacted to drain from the crown at a slope of 2%.
- (6) Proper drainage appurtenances, where required, to prevent washout and excessive erosion, with particular attention to the staging area, so that water draining onto the street surface from the staging area is eliminated to the maximum extent feasible.
- (7) A wear surface, on that portion of the private right-of-way extending beyond the staging area, with a minimum width of 16 feet for its entire length.
- (8) A cul-de-sac, or other teardrop or loop, of not less than 60 feet in radius provided at the end of each terminus, or alternatively, a hammerhead design may be employed with dimensions as approved by the Fire Chief and Director of Public Works.
C. For residential compounds proposed off of an existing private right-of-way, the Planning Board shall require that the applicant improve the existing road to meet or exceed the minimum standard for the residential compound (Subsections A and B above), and if the existing private road will service a total of more than five lots, the Planning Board shall require improvements to exceed the minimum standards contained in Subsections A and B above, including but not limited to paving and drainage improvements. The applicant shall secure the permission and agreement of all parties with legal access to the private right-of-way to perform such upgrades and to be included in a maintenance agreement.
D. Mailboxes shall be located at the entrance to the private right-of-way for access from the Town road. Street numbers shall be clearly marked in compliance with 911 laws.
E. In the event that erosion is causing sediment for the compound to be deposited on Town roads, the compound will be in violation of Chapter 305, Soil Erosion and Sediment Control, and Chapter 450, Land Development and Subdivision Regulations. Owners of the compound lots will be required to take remedial action.
F. Utilities such as electric, phone and cable are allowed to be above ground.
