A Model For Other Towns – Relocating Valmeyer Town To Mitigate Flood Risk
Old Valmeyer Business District
After the 1993 flood destroyed Valmeyer, Illinois, GIS-driven flood analysis guided the relocation of the town to higher ground. Captured in the photo above is the remains of Old Valmeyer’s former business district —a visible reminder of flood risk and mitigation.
Valmeyer Relocation Analysis
As part of my class on GIS Data Formats, Design, and Quality, I created an online web map to update parcel information and digitize new road layers for the town of Valmeyer, which relocated to higher ground to mitigate flood risks.
Tasks Involved
- Updating the new Valmeyer town location parcels with current metrics for elevation and slope.
- Calculating distances from the old town location to assist in disaster management analysis.
- Digitizing new road layers to aid emergency vehicle routing in the new town site.
The project was then shared via a publicly accessible web map on ArcGIS Online here.
