Biennial Inspection of Minor Drainage Structures

Description: A Biennial Minor Drainage Inspection is carried out of drainage structures consisting of pipe and culverts within state rights of ways. This inspection is for drainage openings less than 20 feet in span width, which classifies them as a non-brigde structure inspected by Managers to determine their condition not requiring structural analysis per Federal Law. Every other year, a drainage structure is inspected by Managers to determine their condition. Each drainage structure is located by milepost, direction of flow, county, and state route for asset management. Deficiencies that are found are entered into the Department’s Highway Maintenance Management System (H.M.M.S.) for tracking and scheduling of work purposes.
