This document is a set of construction drawings for the Detroit River International Wildlife Refuge Pavement Restoration and Improvement project. The drawings include site plans, grading and drainage plans, construction details, and electrical schematics for a pavement rehabilitation project at the refuge in Michigan.

The project encompasses site preparation, grading, and surface improvements across multiple areas of the refuge. The drawings specify concrete pavement sections, curb and gutter installations, parking lot layouts, and associated drainage infrastructure. Electrical work includes signage, lighting, and utility connections. Construction details are provided for typical pavement profiles, concrete walk sections, curb inlet sections, and grille longitudinal sections. The drawings incorporate topographic survey data and demonstrate drainage patterns across the site. General notes address existing soil conditions, compaction requirements, and sustainable site design principles. The document serves as the technical reference for contractors to execute the refuge's pavement restoration work in compliance with federal standards and environmental considerations appropriate for wildlife habitat protection.
