Attachment A.1 NSFIH Shoreline Stabilization Phase 4B.pdf

This document is a detailed shoreline layout plan for Naval Support Facility Indian Head Phase 4B, prepared by Coastline Design P.C., dated January 30, 2023. The proposed shoreline restoration project at Stump Neck in Indian Head, Maryland involves stabilizing 500 linear feet of shoreline using comprehensive erosion control measures. The technical drawings include multiple typical sill cross-section profiles and an overall site layout map, demonstrating proposed interventions such as living shoreline techniques, boulder toe installations, sand and gravel fill, filter cloth applications, native plantings, and headland structures.

The project is associated with the Department of the Navy Naval Facilities Engineering Command's Conservation and Rehabilitation of Natural Resources on Military Installations program (CFDA 12.005), which supports environmental management and conservation activities on Department of Defense lands. The cooperative agreement aims to develop a 100% design, secure necessary permits, and implement erosion prevention strategies that will reduce nonpoint source pollution while maintaining compliance with local and state regulatory requirements, including potential permits from Charles County, Maryland, and the US Army Corps of Engineers.
