Part 2 of 7 Final Design Salem Stormwater Drawings_Addendum A.pdf

This document is a phasing and erosion control key plan for a federal construction project managed by the U.S. Department of Veterans Affairs (VA). The plan is prepared by Mabbett, an architectural and engineering firm, and is designated as 100% Final Design documentation for the District Obtain Visitor Discharge project.

The document consists of ten detailed site plans showing six construction phases (Phases 1 through 6) with corresponding erosion and sediment control measures. Each phase map identifies construction areas, materials and equipment storage locations, staging areas, and the placement of erosion control devices including silt fences, construction entrances, sediment barriers, and other environmental protection features. The plans include comprehensive legends identifying temporary erosion control infrastructure, permanent site improvements related to erosion control, and designated no-disturbance areas. Key notes on each plan address contractor responsibilities regarding materials staging, compliance with environmental specifications, proper installation and maintenance of erosion controls, coordination with safety requirements, and the requirement that erosion control devices be installed prior to construction beginning and removed after completion. The phased approach ensures sequential development while maintaining environmental protection throughout the project duration. The project number is QC101, and the documents are dated within the 2010-2025 timeframe based on the footer information provided.
