Residents push consultants to compare new modeling to Richmond's corrected FEMA maps
Summary
A resident said his property — previously cleared of regulatory flood designation after a 2013 correction — appears blue in the consultants' model; he asked the team to overlay the town's corrected regulatory maps so the community can understand differences between regulatory and modeling outputs.
A recurring topic was how the consultant modeling relates to Richmond's regulatory maps. One resident said his property, which was removed from the FEMA-regulated floodplain after an expensive 2013 correction, now appears inundated in the consultant's model and urged an overlay so property owners can reconcile differences.
Consultants responded that this is a non-regulatory analysis and that mapping accuracy and model tolerance can produce differences. They agreed to look at the town's past hydraulic studies and, where feasible, show overlays or explanatory notes in the report so readers can compare the model output and the official regulatory maps. "If you're gonna have a map, you can also have a section that has in your... that is the deferm map," a resident said, requesting a side-by-side comparison for clarity.
