roadways. The OSRD Plan shall incorporate the Four-Step Design Process, according to Section 6 below, and the Design Standards, according to Section 7 below, when determining a proposed design for the development. In addition to those requirements for a Conventional Yield Plan listed in Section 4.A (1), an OSRD Plan shall contain the following information:
Topography at two-foot intervals and approximate location of any wetlands (as defined by MGL Chapter 131, Section 40 and by Sturbridge Conservation Commission Regulations) to include any abutting parcels within two hundred (200’) feet.
The location of existing landscape features, including forests, farm fields, meadows, wetlands, riverfront areas, water bodies, archaeological and historic structures or points of interest, rock outcrops, boulder fields, stone walls, cliffs, high points, major land views, forest glades, major tree groupings, noteworthy tree specimens, and habitats of endangered or threatened wildlife, as identified as primary and secondary resources according to Section 6.A. Proposals for all site features to be preserved, demolished, or altered shall be noted on the OSRD Plan.
The location, names, widths and condition of adjacent streets, approaching or near the proposed development and the proposed lines of streets, ways, driveways, easements and any parcel of land intended to be dedicated for public use or to be reserved by deed covenant for use of all property owners in the development, or parcels of land or lots to be used for any purpose other than private residential shall be so designated within the development in a general manner.
Proposed roadway grades.
Official soil percolation tests for the purpose of siting wastewater treatment options shall be required as determined by the Planning Board. However, a narrative explanation shall be prepared by a Massachusetts Certified Professional Engineer detailing the proposed wastewater systems that will be utilized by the development and its likely impacts on-site and to any abutting parcels of land. For example, the narrative will specify whether individual on-site or off-site systems, shared systems, alternative to Title V systems, or any combination of these or other methods will be utilized. Additionally, the narrative shall describe potential flows and shall explain how the proposal will meet Massachusetts Department of Environmental Protection (MADEP) and local standards for wastewater systems whether individual or shared.
