About this source

US Army Corps of Engineers public datasets. No auth. - searchDams (NID, ~91k dams via bulk CSV, 24h cache) - getRegulatoryDistrict (point lookup → 1 of 39 districts for Section 404 routing) - searchLevees, searchLocksAndDams, searchNavigationFacilities, searchFUDS, searchCorpsProjects - getWetlandRegion (point lookup → wetland supplement region) - getReservoirStatus (CWMS — current pool % for flood/conservation/total) Federal scope: dams, levees, locks, navigation, defense cleanup, civil works projects, reservoir pool levels, wetland-rule supplements. IENC layers have no state/county columns — use bbox or near. CWMS reservoirs and Corps projects also lack STATE; state filters fall back to bbox or district mapping.

    RIBITS acreage/status/permit. State/county match STATE_LIST and COUNTY_LIST.

  • getBankServiceAreas

    read

    Get the service-area polygons a mitigation bank can sell credits into, by bank id.

    Required paramsbankId

    Call searchMitigationBanks first. Returns service areas, not bank records.

  • searchDams

    read

    NID dams. Filters: state, county, bbox, near, hazardClass, ownerType, primaryPurpose.

    Backed by bulk CSV with a 24h in-memory cache (first call hydrates).

  • getRegulatoryDistrict

    read

    USACE regulatory district lookup: district, division, contact for a lat/lon (Army Corps).

    Required paramslatlon

  • searchLevees

    read

    Combined IENC LEVEE_LINE + LEVEE_AREA. Use bbox, near, or a recognized state.

    No county column; unknown state matches nothing. geometryType: line or polygon.

  • searchLocksAndDams

    read

    Locks FS + IENC dam + lock layers. riverSystem accepts curated bboxes.

  • searchNavigationFacilities

    read

    Docks FS (~20.5k). Filters: state, county, bbox, near, facilityType.

  • searchFUDS

    read

    Formerly Used Defense Sites. Filters: state, bbox, near, programCategory. No county column.

    programCategory examples: BD, CON, OE, HTRW, MMRP.

  • searchCorpsProjects

    read

    Corps civil works projects. State filter maps to district codes (no STATE or county column).

    Districts cross state lines: state TX also returns NM/CO rows. Check lat/lon.

  • getWetlandRegion

    read

    Wetland-rule supplement region lookup for a lat/lon (USACE Army Corps).

    Required paramslatlon

  • getReservoirStatus

    read

    CWMS reservoir pool levels (flood/conservation/total). Filter by state/bbox/near.

    poolType default flood. state = bbox (neighbor edge rows); state field blank.

  • getServiceInfo

    read

    Schema + record counts for any of the 9 services (USACE Army Corps of Engineers).
