Weighing a property around Sweetwater? A quick look at the Nolan County flood zone map shows whether it sits in a FEMA flood zone, and it costs nothing to check. What this Nolan County guide covers: finding the address on FEMA's map, reading the zone codes, and confirming the outline on the county map.
Checking the Nolan County flood zone map step by step
The official source is FEMA's Flood Map Service Center: type an address near Blackwell, and choose the dynamic map. A tract near Maryneal without an address can still be found: zoom in from the nearest road then click the parcel area.
Getting to the right map
Parcels around Blackwell appear on the Texas county CAD map, which opens without registering. Closer to Roscoe, type a street address, an owner's name or a parcel number, and the matching parcel lights up. For acreage around Maryneal, write down the parcel ID from that panel; every clerk in the county asks for it first.
Field tips
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Maryneal, so load it before you lose signal. A printout of the tract near Roscoe is a good backup.
Nolan County in a few facts
Sweetwater holds the county offices, where most land records are kept. Smaller places on the map include Blackwell, Roscoe, and Maryneal, where town lots give way to larger tracts. Roughly 14,306 people call Nolan County home (Census estimate, 2023) spread over roughly 912 square miles. The county was organized in 1881, and some chains of title near Roscoe are long.
Who handles what
For assessment questions about property around Maryneal are handled by the appraisal district, which maintains the tax roll. Building or septic questions for a lot near Blackwell are for the local planning and health departments, and the answer depends on jurisdiction.
Zones on the Nolan County flood zone map
For property near Maryneal, A and V zones mark the Special Flood Hazard Area, meaning a 1% or greater chance of flooding each year. For land near Maryneal, a shaded X area marks moderate flood hazard, roughly the 100- to 500-year range; unshaded X means minimal mapped risk.
A short flood checklist
Request for any Elevation Certificate for the house near Maryneal; getting a quote early avoids surprises.
Use the county map alongside FEMA
FEMA doesn't draw property lines, so pair it with the Texas county CAD map to see exactly which lot near Blackwell you're looking at.
Low spots and local drainage
Small streams around Maryneal may not have detailed mapping, so ask neighbors about past flooding. Wet ground around Blackwell is a separate issue from flood zones; the National Wetlands Inventory mapper shows mapped wetlands.
Recorded documents worth pulling
When the details count, get the recorded deed from the County Clerk; the viewer just points to it, whether the land is near Blackwell or elsewhere in the county. Long-held tracts near Blackwell can sit on a long string of deeds, so a title company is worth hiring on a real sale.
Next door to Nolan County
The county meets Coke County, Fisher County, Jones County, Mitchell County, and Runnels County, and each of those keeps its own parcel map for land near Maryneal. Acreage along the edge near Blackwell may show up across two assessors' files, so open the neighboring map too. With a lot near Blackwell, the Platbookmapper state page links each neighboring county map across Texas.
Money questions tied to the zone
If the land is near Sweetwater, an Elevation Certificate from a surveyor helps: it can change the insurance price a lot. New construction in a floodplain near Sweetwater can trigger elevation rules; check with the county or town building office early.
A word on accuracy
For a parcel near Roscoe, acreage on the record is an assessed number; only a licensed surveyor sets the real lines on the ground. For a home near Blackwell, owner names and values update on a schedule, so a deed recorded last month can take weeks to appear.
Reading the legal description
Rural deeds near Roscoe commonly use metes-and-bounds descriptions, a series of courses and distances from a starting point. Subdivision lots in Sweetwater usually use lot and block from a recorded plat instead, making them easier to find. Keep the legal description for land near Blackwell for any title or survey request.
