The Wisconsin Coastal-Management Data Infrastructure (WICDI) Project provided data, tools and training to coastal communities in Wisconsin. Increased frequency and intensity of rain events can cause damage to infrastructure including culverts. Culverts were inventoried and mapped to help identify at-risk culverts and justify infrastructure upgrades or replacements. WICDI provided resources needed for coastal and culvert managers to quickly and appropriately respond to damages or identify vulnerable culverts before catastrophe.

What You’ll Find in the Inventory & App

One of the outputs of the WICDI project is a standardized culvert database, developed with support from partners across the state.

The database is available for download with full metadata from geodata@wisconsin here. An online culvert app, allowing access to the dataset, is available here.

The app differentiates culverts using symbology based on data source. Each culvert can be clicked on to get the full list of attributes and values. Download of the dataset from the app is facilitated with a link to the Geodata@Wisconsin record.
