About this file
This is a civil engineering design drawing for the Seward Housing project located in Seward, Alaska, prepared by the U.S. Coast Guard Civil Engineering Unit in Juneau. The drawing, designated as sheet C-201 (Typical Sections), is part of the final design for construction dated December 2025 and was developed by BDS Architects in Anchorage, Alaska, with consulting engineering services provided by RESPEC Company, LLC.
The drawing presents two typical cross-sectional details for the housing development: Support Building Option 1 Typical Section (F1) and Duplex Typical Section (D1). Both sections illustrate site grading and fill requirements, including structural fill compacted to 95% maximum density per ASTM 1557d standards, placement in lifts not exceeding 12 inches, and a 4-inch topsoil layer with seeding on improved areas. Key design features include a 6-foot high wooden fence, a 5-foot maximum retaining wall, a 1.5% minimum/6% maximum slope on the asphalt driveway along Phoenix Road, and organic material removal from building footprints and driveways. The sections show existing ground conditions, finish grades, and structural fill requirements to accommodate building placement and site improvements. The USCG project number is 13611688, with the A/E project number 525001.000.
