Tennessee two-site — official parcel, GIS, flood, and climate portals (primary references)

Purpose: Stable pointers to official or primary web tools used for desk research on SITE_HOME (Anderson County, Claxton) and SITE_FARM (Campbell County, Demory)—without embedding parcel-specific outcomes in the wiki. Use with Parcel evidence intake and validation workflow — two-site and Tennessee two-site — evidence hardening audit (2026-04).

Not provenance for: Legal boundaries (use deed, survey, recorded plat); utility depths (use 811 locate + as-builts); soil management interpretations (use local NRCS + Extension).

Evidence summary

Field Content
Abstract Primary URL index for desk research on Claxton / Demory planning anchors: TN statewide parcel viewer, county assessor entry points, WSS, USGS elevation, FEMA flood maps, NOAA climate normals—no parcel outcomes embedded.
Authority mix State / county .gov tools + federal agencies (NRCS, USGS, FEMA, NOAA)—no third-party aggregators as authorities.
Decision relevance Screening access, drainage, flood hazard, soils process, seasonal norms—supports parcel worksheets and V*/G* gates; does not replace deed, survey, or local floodplain determination.
Canonical wiki links Local evidence package — East Tennessee two-site · Parcel intelligence package · Parcel evidence intake workflow · Evidence hardening audit (2026-04)

Key claims (public-safe):

  • TN Property Viewer and county assessor maps are not legal surveys—official disclaimer language applies.
  • FEMA MSC is for NFIP map desk screening; LOMR / local admin may supersede.

Open questions / follow-ups

  • Homestead WSS AOI capture in raw/ when filed.
  • Nearest NOAA station choice vs on-farm weather telemetry.

Statewide — property and assessment mapping

Resource URL Role
TN Property Viewer (Comptroller / TNGIC) tnmap.tn.gov/Assessment/ State map viewer for assessment parcels; search by county, owner, address, parcel ID; includes imagery and FEMA flood overlay options per viewer documentation. Disclaimer: map ≠ legal survey.
TN Comptroller — Property Assessments comptroller.tn.gov/office-functions/pa/ Hub for assessment programs, parcel data stewardship, links to RE assessment search tools.
TN Real Estate Assessment Data (parcel search) assessment.cot.tn.gov/RE_Assessment/ Searchable assessment records (coverage per state disclosure—not all functions are statewide uniform).

County assessor — Anderson (SITE_HOME)

Resource URL Role
Anderson County Property Assessor — GIS acassessor.com/geographic.html County GIS entry; links Web App for parcel visualization. Disclaimer on site: mapped data not a legal survey—verify with deed / County Clerk.
Anderson County Property Assessor — search acassessor.com/search.html Property search landing.

County assessor — Campbell (SITE_FARM)

Resource URL Role
Campbell County — Property Assessor (official county site) campbellcountytn.gov/elected-officials/property-assessor/ Office hub: reappraisal cadence, contact, links to state search tools for maps/values.

Soils — national (operating area)

Resource URL Role
Web Soil Survey (WSS) websoilsurvey.nrcs.usda.gov NRCS — define AOI, soil map, interpretations for land use. Process capture in vault: Web Soil Survey — product home page (capture).
SSURGO / gSSURGO (data products) nrcs.usda.gov/wps/portal/nrcs/detail/soils/survey/geo/?cid=nrcs142p2_053627 National soil survey data products—not a substitute for WSS workflow on your AOI.

Elevation / topography (United States)

Resource URL Role
USGS National Map / 3DEP usgs.gov/the-national-map-data-delivery Elevation and topographic products; use for rough slope/drainage desk context—field verify.
USGS TN usgs.gov/centers/tennessee-water-science-center Regional water science context; not parcel engineering.

Flood hazard (United States)

Resource URL Role
FEMA Flood Map Service Center msc.fema.gov/portal/home Official NFIP map search and FIRMette exports. Use for regulatory flood zone desk screening—confirm with local floodplain admin if building or insuring.
FEMA — Flood zones explained fema.gov/flood-insurance/rate-map/flood-zones Educational context for zone letters—not a site determination.

Climate — normals and historical climate (United States)

Resource URL Role
NOAA NCEI — U.S. Climate Normals ncei.noaa.gov/products/land-based-station/us-climate-normals Normals (temperature, precipitation, etc.) for station-based planning—pick nearest representative station; not microclimate at a fence line.
NOAA — Climate.gov climate.gov Portal for regional climate narratives and tools—supporting context only.
