Culvert Inventories

WRC GIS staff can assist your town with conducting and updating culvert inventories. A typical inventory includes inventory consists of, 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.

Inventory data is entered into the Vermont Online Bridge Culvert Inventory Tool (VOBCIT), available at For towns, WRC creates a large map (3 feet by 4 feet), a large-scale culvert atlas, and a spreadsheet of information about all culverts in town. Some towns do their own inventory updates directly in VOBCIT and have WRC just create the maps.

WRC has begun doing a higher level of inventory on larger culverts as part of several Better Backroads projects. We examine the culvert and nearby stream segment to see if there might be some geomorphic issues, and if so, recommend that an engineer or river scientist take a closer look.


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.

Culvert Data

The status of each town’s culvert data is shown below.

All culvert data are stored in the Vermont Online Bridge Culvert Inventory Tool (VOBCIT), available at WRC can make available in digital or paper format any map, atlas, or spreadsheets we have created for each town. Simply contact a WRC GIS staff member.
