The drawings include site plans, profiles, and detailed construction specifications for the culvert, nature-like weir, stream channel modifications, erosion control measures, and planting plans. Key components include a 12'x8' precast concrete box culvert, boulder-armored channel bed, stream bank stabilization using coir fiber matting and native plants, and extensive landscape restoration using native trees and shrubs. The project also includes a temporary traffic detour plan, roadway modifications, and detailed planting specifications listing specific native plant species and their required sizes and spacing.
