What this data holds
- Acreage isn't in EPA's national data, so we don't show site sizes.
- We hold no flood data for these sites.
- We show the city and county, not street addresses.
- Zoning: Check zoning with the city.
- Grant recipients report these sites to EPA. A flag is EPA's record, not a site visit.
