This layer displays possible locations of culvert structures on the county and local road networks in the state of Wisconsin. The layer was developed using other sources that were combined into the WICDI Culvert Database. Duplicate locations as well as structures on the state, US and interstate highway systems were removed from these locations to the extent practical, although some locations may remain. This layer is not to be considered as an all-inclusive list of culvert locations, but rather to be used as a starting point to begin collecting inventory data on pipe, box, arch, and small bridge structures with a span along the roadway between 6 feet and 20 feet. Field reviews of these locations will be required.
<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN STYLE="font-size:12pt">This data set begins the process to collect the inventory data on small bridge and large pipe structures between 6 feet and 20 feet in span length, as measured along the roadway required by the current state budget.  Locations must be field verified and basic structure data gathered.  Data from this data set can be downloaded from the WisDOT Open GIS Data website, filtered for the specific county or municipality doing the collections.  Data can be downloaded as a CSV, KML or shape files depending on the end user's capabilities to view and use the data.  Once downloaded, the locations must be field verified and updated using the Excel template spreadsheet provided by BOS.  A word and editable PDF have also been created for those that prefer printed copies or for structures that are not included in the data set provided.  These files can be found at the following link, along with basic instructions.</SPAN></P><P><SPAN /></P><P><SPAN STYLE="font-size:12pt">All found structures shall be consolidated into the template spreadsheet using the provided headings and data lists to be used to collect the inventory.  Once complete, this spreadsheet will be sent back to the BOS State Ancillary Structures PM for inclusion into the HSIS database.  Each county should consolidate the local municipalities into a single spreadsheet to send to BOS.  It is critical that for this initial inventory, only fields shown on the form and spreadsheet are used to allow for efficient transfer of data into HSIS.  Any critical findings or serious concerns regarding structures found shall be immediately forwarded to the structure's owner and the county so the condition issues can be addressed.</SPAN></P><P><SPAN STYLE="font-size:12pt">While the initial inventory is being collected, other procedures for inspection, maintenance, etc. will be developed.</SPAN></P></DIV></DIV></DIV>
