This document is a U.S. Army Corps of Engineers contract amendment for the Brunswick Harbor Entrance Channel Widener Maintenance project, solicitation number W912HN-25-B-A021. The amendment, dated 11 December 2025, updates contract drawings for sheets VH102 (Revision 3), VH105, VH106, and VH109 (all Revision 2). The project involves maintenance dredging of the Brunswick Entrance Channel in Glynn County, Georgia, with specific survey data and dredging area boundaries detailed across multiple sheets. The drawings include precise soundings, navigation channel critical points, and notes about anomalies that must not be disturbed, with most anomalies having a 100-foot buffer zone and one (A6) having a 50-foot buffer. The survey was conducted in February 2025 and uses Mean Lower Low Water (MLLW) vertical datum and NAD83 Georgia State Plane East horizontal datum.
