Research notes
State no-net-loss regime that runs alongside Clean Water Act §404 and §401 water-quality certification. Coordinated through the joint federal-state Wetland Permit Application. Per-parcel geographic predicate keyed to National Wetlands Inventory + local LGU-mapped wetland inventory. Federal conflict check enabled for §404 / §401 overlap.
