Culvert Inventories

Every town in the Windham Region has culvert inventory.  A typical inventory includes, at a minimum, information on material, size, condition, location, and header type and condition. Inventories often are conducted by a WRC GIS staff person along with a member of the town road crew.  WRC GIS staff can assist your town with conducting and updating culvert inventories.

Inventory data are stored in Vermont's culvert data website,  VT Culverts (vtculverts.org, or https://vt-culverts-vapda.hub.arcgis.com/) . For many towns, WRC creates a large map (generally 3 feet by 4 feet), a multi-page culvert atlas, and a spreadsheet of information about all culverts in town. 

Why Conduct an Inventory?

A culvert inventory can be useful for many purposes, including creating a culvert repair and replacement schedule for capital improvement planning, documenting culvert condition at a specific point in time ahead of another flood event, and more easily identifying which culverts are damaged during a future flood event for hazard mitigation planning and disaster reimbursement.
