6.18.3 Requirements:

Tree size and planting shall conform to the requirements of Appendix VII, Tree Planting Specifications.

Guard rails shall be installed in all areas where fill slopes in excess of the required 3:1 have been approved. Appropriate slope treatment and erosion control measures shall be provided for all slopes in excess of 3:1 and rip-rap may be required on all slopes in excess of 2:1, unless otherwise specified by the Board.

Street signs shall be installed at all intersections in conformity with the specifications of the Department of Public Works. Until such time as each street is accepted by the Town as a public way, the sign posts at the intersection of each street with any other street, shall have affixed thereto a sign designating such street as a private way. Upon application for acceptance of the streets, the costs for advertising for hearing, for data collection in support of the street acceptance, for permanent signs and for any other costs related to the acceptance of the street shall be paid by the applicant.

Provisions shall be made for street lighting connections at locations determined by the Board.

No rule or regulation shall require, and no Planning Board shall impose, as a condition for the approval of a plan of a subdivision, that any of the land within said subdivision be dedicated to the public use, or conveyed or released to the Commonwealth or to the county, Town or Town in which the subdivision is located, for use as a public way, public park or playground, or for any other public purpose, without just compensation to the owner thereof.

Before approval of a plan by a Planning Board, said Board shall also in proper cases require the plan to show a park or parks suitably located for playground or recreation purposes or for providing light and air and not unreasonable in area in relation to the area of the land being subdivided and the prospective uses of such land, and if so determined said Board shall by appropriate endorsement on the plan, require that no building may be erected on such park or parks for a period of not more than three years without its approval.

The final grading shown on any approved Form C plan shall not be amended or changed without prior review and approval of the Board except as may be deemed minor by the Board's staff as defined in Section VI.F.7. below. In reviewing proposed amendments or changes, the Board shall consider the impact of such amendments or changes upon the subdivision as: a) changes in the direction of storm water; b) changes in velocities of runoff; c) impacts on abutting properties; d) impacts on street drainage systems; e) impacts on natural drainage channels, water courses or streams.

Lot slope requirements in the residential zoning districts shall be as follows:

a. The slope of land at any point, stated as a percentage, shall be defined as the change in elevation over a horizontal distance measured perpendicular to the contours divided by the distance over which the change occurs multiplied by 100.

Slope = (Change in elevation/horizontal distance measured perpendicular to contours ) x 100

b. All natural slopes exceeding 25% over a horizontal distance of 10 feet as measured perpendicular to the contour are protected and shall remain in their natural state.

c. All cut-and-fill slopes within or contiguous to the street right-of-way shall be planted with suitable, well rooted, low growing plant materials or grass as determined by the Board, with advice from the Board's Designee. A wood chip or comparable mulch shall be used with ground cover plants to minimize erosion. Planting of sod may be required.
