Attachment 11 - Erosion and Sediment Control Plan (APP E).pdf

This is an Erosion and Sediment Control Plan (ESCP) appendix for a federal construction project at U.S. Army Garrison Fort Wainwright, Alaska.

The project involves repair of a deteriorated parking lot at Building 3200, covering 0.11 acres of gravel shoulder and area behind sidewalk repairs, with a total existing asphalt parking lot of 7,278 square yards. ACME Construction Inc. is the contractor, with work scheduled from January 30, 2020 to May 30, 2020. The ESCP outlines site control measures including installation of erosion control Best Management Practices (BMPs) such as fiber rolls/wattles as perimeter sediment control, catch basin inlets protected with silt fabric and straw wattles, and on-site detention with sediment collection and reuse. The plan requires temporary soil stabilization measures including compaction and mulching if construction activity ceases for more than 14 days. Construction access routes will be marked and maintained, with paved surfaces swept daily to prevent debris and material spillage. Inspections will be performed every seven calendar days and documented using the provided ESCP Construction Inspection Report form (Attachment A), which captures general project information, weather conditions, site-specific BMP compliance, and overall site issues including stabilization measures, perimeter controls, discharge points, storm drain inlet protection, sediment tracking, trash management, and equipment fueling practices. A final inspection will verify stabilization completion and removal of temporary BMPs, serving as the project closeout.
