Polygon Section 106 / NEPA screening

Click the map to drop a center point and choose a buffer (or drag a polygon shape), then run a single-click screening that intersects against every layer SHPO owns: BLM SMA, NPS units, tribal nations, FEMA NFHL, ADOT historic routes, AZ State Parks, EPA Superfund (NPL/non-NPL), the entire NRHP catalog, NID dams, FHWA NBI pre-1945 bridges, HIFLD cell towers, and OSM historic features.

Why this matters

Today, SHPO reviewers manually compose this screening report by opening 8-10 GIS tabs and cross-referencing PDFs. The 2023 RFI estimated $3.5M for a custom-built equivalent. Here it’s a single page powered by open data with the same layer set the agencies publish authoritatively.
