What to check before buying land in St. Francis County

Ordered by what St. Francis County's numbers point to. Every parcel differs, so treat this as where to look first.

  1. 1.Expect wetlands; map them before you plan

    About 60% of St. Francis County's mapped soils are hydric (formed under saturated conditions, a federal wetland indicator) and 58% are poorly or very poorly drained (USDA SSURGO).

    Open the National Wetlands Inventory mapper at the parcel. Filling or draining a wetland can need a Clean Water Act Section 404 permit, and wet ground limits septic fields and building pads.

  2. 2.Budget for a perc test and maybe an engineered septic

    USDA rates 100% of St. Francis County's mapped soils "very limited" for conventional septic absorption fields and 0% "not limited".

    Without city sewer you need a septic permit from the county or state health department. Make the offer contingent on a passing soil or perc test; mound and aerobic systems can cost several times a conventional one.

  3. 3.Put flood checks first in St. Francis County

    21% of the county's area is in the 1%-annual-chance (100-year) floodplain FEMA's National Risk Index uses for inland flooding; 12% of its mapped soils flood occasionally or frequently.

    Look up the FEMA flood zone at the pin, not the parcel's address. If any of the land is in zone A or V, price flood insurance before you offer, ask for an elevation certificate, and check whether the access road floods too.

    Guide: Flood zones before buying land

  4. 4.Confirm legal road access and power

    The 2020 Census classified 99% of St. Francis County's land area as rural.

    Rural tracts are often sold without recorded access or a power line nearby. Get the title company to confirm a recorded easement or public road frontage, and ask the electric co-op what a line extension costs.

  5. 5.Find out where the water comes from

    At least half of St. Francis County was in severe drought (D2) or worse in 15% of the 262 weekly U.S. Drought Monitor maps from 2021 to 2026.

    Ask whether the land has a public water connection, an existing well (and its log and yield), or neighbors' well depths from the state well database. For a new well, check permits and typical depth with the state agency first.

    Guide: Wells, public water and water rights

  6. 6.Sanity-check the price per acre

    Farm real estate in St. Francis County averaged $3,503 an acre including buildings in the 2022 Census of Agriculture, and 26% of its mapped soils are prime or of statewide importance.

    Compare the asking price with recent sales of similar tracts, not the county average, which mixes cropland, pasture, timber and homesites. If an ag tax valuation applies, ask what the rollback taxes would be if you change the use.

It says how common flood-prone land is in St. Francis County, not whether a given parcel floods. For that, look up the zone at your exact point on the FEMA Flood Map Service Center or run the free check.

Questions about buying land in St. Francis County

How much of St. Francis County, AR is in a flood zone?

About 21% of St. Francis County's area is in the 1%-annual-chance (100-year) floodplain used by FEMA's National Risk Index (December 2025), 13th highest of 75 counties in Arkansas. Whether a given parcel is in a flood zone depends on its exact location, so check the FEMA map at your pin.

How much does land cost per acre in St. Francis County?

The 2022 Census of Agriculture put the average value of farm land and buildings in St. Francis County at $3,503 an acre, 34th lowest of 75 counties in Arkansas (the median Arkansas county was $3,631). It's a self-reported average across farms, so small homesites and recreational tracts often sell for more per acre.

Will a septic system work on land in St. Francis County?

Often, but test first. USDA soil surveys rate 100% of St. Francis County's mapped soils very limited for conventional septic absorption fields, usually because of wetness, slow permeability, shallow rock or flooding. A perc or soil test on the parcel decides what system the health department will permit.

Is there good farmland in St. Francis County?

19% of St. Francis County's mapped soils are prime farmland, 61% are prime only if drained, irrigated or protected from flooding, and 6.4% are farmland of statewide importance (USDA SSURGO). The 2022 Census of Agriculture counted 211 farms averaging 1,356 acres.

How often is St. Francis County in drought?

Since 2021, at least half of the county was in severe drought or worse in 15% of weekly U.S. Drought Monitor maps, and in extreme drought in under 1%. On 2026-10-27, 100% of the county was in moderate drought or worse.

Check the parcel, not just the county

County numbers tell you what to look for. The free check looks at your exact point in St. Francis County: flood zone, slope, soils, wetlands, roads, power and more. The full report is $29.

What these numbers can't tell you

  • County shares describe St. Francis County as a whole; a parcel can be entirely in or out of a flood zone, wetland or poor soil.
  • It doesn't look at the whole parcel, its boundaries, title, easements, zoning or permits.
  • It isn't a survey, appraisal, elevation certificate, soil or perc test, or Phase I environmental site assessment.
  • It can't see local distribution power lines, driveways, legal access, wells or mineral rights.
  • Maps lag behind the ground, and distances are straight-line, not driving distance.
