What to check before buying land in Ray County

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

  1. 1.Put flood checks first in Ray County

    22% of the county's area is in the 1%-annual-chance (100-year) floodplain FEMA's National Risk Index uses for inland flooding; 31% 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

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

    USDA rates 96% of Ray 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.

    Guide: Perc tests and septic systems

  3. 3.Confirm legal road access and power

    The 2020 Census classified 99% of Ray 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.

  4. 4.Check wildfire exposure and insurance

    FEMA rates Ray County's wildfire risk very low, and 28% of the county's area is in the wildfire exposure zone the National Risk Index uses.

    Ask an insurer for a quote early; some carriers won't write new policies in high-hazard areas. Check access for fire trucks, nearby fire stations and the vegetation around the building site.

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

    About 16% of Ray County's mapped soils are hydric (formed under saturated conditions, a federal wetland indicator) and 13% 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.

  6. 6.Check the soils if you plan to farm, graze or garden

    Farm real estate in Ray County averaged $5,276 an acre including buildings in the 2022 Census of Agriculture, and 41% 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.

The floodplain share is the area FEMA's National Risk Index counts as exposed to inland flooding, mostly mapped 100-year flood zones. It says how common flood-prone land is in Ray 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 Ray County

How much of Ray County, MO is in a flood zone?

About 22% of Ray County's area is in the 1%-annual-chance (100-year) floodplain used by FEMA's National Risk Index (December 2025), 16th highest of 115 counties in Missouri. 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 Ray County?

The 2022 Census of Agriculture put the average value of farm land and buildings in Ray County at $5,276 an acre, 33rd highest of 114 counties in Missouri (the median Missouri county was $4,462). 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 Ray County?

Often, but test first. USDA soil surveys rate 96% of Ray 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 Ray County?

18% of Ray County's mapped soils are prime farmland, 14% are prime only if drained, irrigated or protected from flooding, and 23% are farmland of statewide importance (USDA SSURGO). The 2022 Census of Agriculture counted 958 farms averaging 271 acres.

How often is Ray County in drought?

Since 2021, at least half of the county was in severe drought or worse in 3.1% of weekly U.S. Drought Monitor maps, and in extreme drought in 0%. On 2026-10-27, 0% of the county was in moderate drought or worse.

Can I check a specific property in Ray County?

Yes. Enter the address or drop a pin anywhere in Ray County on the free check. It shows which checks return data at that exact point, and the full report costs $29: flood zone, slope, soils, wetlands, roads, power lines, wildfire and more, each with its source.

Check the parcel, not just the county

County numbers tell you what to look for. The free check looks at your exact point in Ray 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 Ray 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.
