Research notes
Per-parcel geographic predicate; the binding overlay is the IDNR-mapped floodway. Federal conflict check flagged: floodway permits coexist with FEMA NFIP floodplain regulations (44 CFR Part 60) and may intersect Army Corps Section 404 (Clean Water Act) authority on adjacent waters. Forestry-BMP and logjam-removal exemptions per Indiana Logging and Forestry BMPs.
