Api Locus Environmental History Lookup

Address-level environmental record proximity. Perfect for: 'environmental hazards near an address', 'EPA TRI / RCRA sites near a property', 'is there a polluter nearby', 'radon zone for an address', 'environmental due diligence for a property'. Returns proximity-ranked EPA Toxics Release Inventory + RCRA facilities, nearest large-quantity generator, and the county radon/background composite. National. Not a contamination or safe/unsafe verdict.

Locus

Api Locus Flood Zone

FEMA flood zone for an address. Perfect for: 'flood zone for an address', 'FEMA flood designation', 'is this property in a floodplain', 'is this address in a 100-year flood zone', 'flood risk lookup'. Returns the FEMA NFHL flood-zone designation, 0.2%-annual-chance and BFE/floodway flags at the geocoded point, with source provenance. National. Not a flood insurance quote or a safe/unsafe verdict. Charge-free when the flood lookup fails.

Locus

Api Locus Nei Emissions Nearby

EPA National Emissions Inventory facility and pollutant rows near an address. Perfect for: environmental diligence, facility emissions research, per-pollutant tonnage, and distance-ranked industrial context. Summary is bounded; detailLevel=full returns the large facility-pollutant matrix. Periodic inventory estimates only, not monitoring, ambient concentration, exposure, health evidence, or a burden score. Charge-free when no facility rows resolve.

Locus

Api Locus Pfas Occurrence

EPA UCMR 5 PFAS results for an address or explicit PWSIDs. Perfect for: 'PFAS results for this address', 'was this utility tested for PFAS'. Addresses resolve via EPA service-area boundaries (point-in-polygon) with per-boundary provenance and confidence (provider vs machine-modeled); containment is evidence, not proof. Detection and non-detect counts stay distinct; lithium excluded. Entry-point samples, not a tap; no safe/unsafe verdict. Charge-free when out of coverage or unresolved.

Locus

Api Locus Workplace Employment Context

Census LODES workplace jobs and broad industry sectors within a radius. Perfect for: commercial site selection, tenant diligence, daytime employment, and labor context near a selected site. Returns annual block-level aggregates only; excludes worker demographics. Jobs are not shoppers, visits, foot traffic, sales, demand, or a forecast. Charge-free when the state snapshot is missing, stale, unavailable, or no workplace block falls in the radius.

Locus

Api Locus Zoning

Zoning district + overlays for an address. For 'what is the zoning', 'is this parcel being rezoned', 'zoning changes near an address', 'is nearby redevelopment changing this area'. Returns the official district/overlays from wired municipal/county layers. Zoning matters most as a CHANGE (rezonings, zoning bills) and vs NEIGHBORS; pair with development cases, legislation, capital projects, transfers. Not a buildability, variance, entitlement, or value ruling. Charge-free when out of coverage.
