There are over 1,600 documented culverts and small bridges in the SNHPC region, each one has been assigned a score based on risk factors. You can explore stream crossings in your community in the GIS map below. We encourage you to use this resource to learn more about crossings in your area and as a communication tool for discussing vulnerability.
