Site Due-Diligence Bundle — One-Call Fatal-Flaw Scorecard

Takes a coordinate and a radius and returns one site-screening scorecard that runs fifteen environmental, hazard, regulatory, and opportunity checks at once, instead of calling fifteen separate actors. Each site comes back as a single row with a rolled-up fatal_flaw_count, a flags list, an opportunities list, and a plain-language summary. Built as a fast pre-screen for site selectors, developers, and the consultants who scope the real studies.

What it screens (15 layers)

Layer (layers key)	Source	Result type
epa_contamination	EPA ECHO (echodata.epa.gov) — RCRA hazardous-waste handlers and TRI reporters within the radius	flag
flood_risk	FEMA National Risk Index (county) resolved via the FCC block geocoder	flag on high inland/coastal flood risk
critical_habitat	USFWS ESA Critical Habitat, Final + Proposed	flag (ESA Section 7)
protected_lands	USGS PAD-US protected/conservation lands (point-in-polygon)	flag
seismic_design	USGS ASCE 7-16 seismic design web service	flag on high Seismic Design Category / site-specific study
wildfire_exposure	NIFC WFIGS active perimeters and incidents	flag when in or near an active fire
karst_terrain	USGS CONUS_Karst national karst/pseudokarst compilation (OFR 2014-1156), 7 layers	flag — Elevated (near-surface soluble rock) or Moderate (buried/pseudokarst) tier
landslide_hazard	USGS US Landslide Inventory (mapped polygons + points)	flag — inside a mapped slide, or a mapped slide within the radius
levee_proximity	USACE National Levee Database (NLD) Leveed Areas	flag — behind a mapped levee, with an editorial 0–100 levee_risk_score
impaired_waters_303d	EPA ATTAINS Clean Water Act §303(d) impaired/threatened waters (Esri Living Atlas mirror)	flag — in or near a listed/impaired waterbody, with listed pollutant causes
transmission_grid	HIFLD transmission lines + substations within the radius	opportunity (interconnection proximity)
ira_energy_community	DOE/NETL IRA energy-community layers (coal closure + Fossil Fuel Employment MSA)	opportunity (10% ITC / +10% PTC bonus)
state_tank_spill_registry	EPA UST Finder national baseline (registered UST facilities + LUST releases) plus state registries — NY DEC Spills (Socrata), CA SWRCB GeoTracker, TX TCEQ PST/LPST, FL DEP petroleum contamination — within the radius	flag on any currently open case; registered tank facilities are counted but informational
gas_pipeline_proximity	US DOT NTAD Natural Gas Pipelines (sourced from EIA) — nearest pipeline segment and right-of-way encroachment band	flag when the nearest pipeline is inside the tight <500ft band
calfire_fhsz	CAL FIRE Fire Hazard Severity Zone (SRA/LRA/pending/federal), California only	flag on a Very High FHSZ hit; outside California is an informational clear

Every layer returns { status: clear | flag | opportunity | unavailable, detail, metric fields, citation }. A layer that errors upstream is marked unavailable — never silently reported as clear — and one bad layer or one bad coordinate never crashes the run. National wildfire data is fetched once per run and reused across all sites; the impaired-waters FeatureServer base URL (which Esri renames quarterly), the NY tank/spill geo capability, and the EPA UST Finder service name are also resolved once per run and reused. The CAL FIRE FHSZ layer resolves its layer-role IDs once per run too, and skips the network call entirely for any asset outside California.

Key output fields (one scorecard row per site)

• fatal_flaw_count — how many of the fifteen layers returned flag. Zero means nothing flagged; null if the coordinate was invalid.
• flags — each flagged constraint as a readable sentence (contamination, flood, critical habitat, protected land, high seismic, active wildfire, karst/sinkhole susceptibility, landslide hazard, behind a levee, impaired waterbody nearby, an open tank/spill case, a gas pipeline inside the <500ft band, a Very High CAL FIRE FHSZ hit).
• opportunities — positive findings (grid interconnection proximity, IRA energy-community bonus eligibility).
• unavailable_layers — layers that could not be screened this run (upstream error/timeout), treated as not-screened rather than clear.
• layers — the full per-layer object with each verdict, its metrics, and its citation.
• site_screen_summary — one-line roll-up.
• radius_miles, disclaimer, checked_at, error.

How radius works

radiusMiles (default 1; 1–25 in the Console editor, down to 0.25 via API) drives the distance-based layers: EPA, critical habitat, grid, the wildfire proximity flag, the landslide nearby-search, the impaired-waters proximity check, the state tank/spill registry, and the gas-pipeline proximity check. The point-in-polygon-only layers — protected lands, flood/NRI county, seismic, IRA energy-community, karst terrain, the USACE levee check, and the CAL FIRE FHSZ check — are exact intersect tests and ignore it.

Who uses it

• Site selectors and corporate real estate teams pre-screening a shortlist of parcels for deal-killers before ordering full studies.
• Renewable-energy and infrastructure developers checking grid proximity and the IRA energy-community bonus alongside the full environmental/hazard constraint stack in one call.
• Phase I ESA and environmental consultants scoping the assessment with a fast regulatory-records and sensitive-receptor read.
• CRE lenders and insurers pulling flood, wildfire, seismic, karst, landslide, levee, contamination, tank/spill, pipeline, and CalFire wildfire-zone exposure on a collateral address.
• AI agents turning a coordinate into a structured constraint profile.

FAQ

Is this a Phase I Environmental Site Assessment? No. It is an informational multi-source pre-screen to scope and prioritize — not a substitute for an ASTM E1527 Phase I, a legal ESA or land determination, a flood certificate, a stamped engineering study, or tax advice. Confirm every flag with the authoritative agency and a licensed professional.

What isn't screened? The EPA layer covers RCRA and TRI facilities via ECHO; Superfund/SEMS records without coordinates, the IRA brownfield category, and NWI wetlands are out of scope, so a clear result does not rule those out. (The standalone epa-contaminated-site-screener actor covers six EPA programs if you need deeper contamination detail.) The karst, landslide, levee, and impaired-waters layers are also compiled national datasets that can lag ground truth or draw boundaries conservatively/coarsely — a "clear" result on any layer does not rule out an undocumented local condition, and nearest_distance_* fields on the landslide and impaired-waters layers are straight-line proximity proxies, not drainage or engineering delineations. The tank/spill registries layer carries a national EPA UST Finder baseline (registered UST facilities + LUST releases anywhere in the US) plus deeper state spill/cleanup registries in NY, CA, TX, and FL — TX/FL records without coordinates are matched at county level, and outside those four states state-level spill cases beyond the EPA baseline are not screened; the CAL FIRE FHSZ layer covers California only (elsewhere it is an informational clear with no network call); and the gas-pipeline proximity layer flags only the tight <500ft right-of-way band — a pipeline farther away is informational only, not a fatal-flaw flag.
