Tree Canopy Clearing - Amend 0005.pdf

This document is a technical drawing detailing tree canopy clearing specifications for a walkway installation in an environmentally sensitive area, likely part of the SERE Parking Lot Expansion project for the Department of the Navy Naval Facilities Engineering Command. The drawing provides specific guidelines for selective hand clearing, including requirements that no grading, filling, or land-disturbing activities occur beyond specified areas, and all work through wetland areas must be completed from temporary matting or uplands to prevent site disturbance.

Key technical specifications include: maintaining a 6-inch height differential between existing grade and walkway, cutting vegetation under the wood walkway to allow installation, and ensuring all clearing is done manually with no mechanized equipment. The drawing emphasizes preservation of the natural environment, specifying that existing vegetation should be minimally altered, debris must be removed from the project site, and all hand clearing must be reviewed and approved by the contracting officer prior to commencing work. The technical details suggest a precise and environmentally conscious approach to site preparation for the walkway installation.
