VRLB Grading and Drainage Plan.pdf

This is a Grading & Drainage Plan, a technical construction drawing showing the site plan for a project at the scale of 1"=30'. The plan illustrates the grading layout, drainage systems, and utility infrastructure for what appears to be a commercial or institutional facility. Key features depicted include enhanced swales (#1A, #1B, #1C) for stormwater management, perforated finger drains with 4" diameter piping, and a 6" storm pipe system. The plan designates specific elevation points (ELEVs) for various spots and features, including spot elevations ranging from approximately 450 to 467 feet. The drawing identifies critical infrastructure elements such as sanitary line-A, limits of construction areas, and multiple headwall installations with designated drainage coefficients (DAP 4.31). The plan also indicates asphalt paving areas along Brainard Avenue and defines areas with specific finishing treatments. Numerous reference numbers (453-465) correspond to different sections of the grading and drainage work. This technical document would serve as construction guidance for contractors implementing site grading, stormwater management, and associated drainage infrastructure improvements.
