Weighing a property around Waskom? The Longview flood zone map tells you whether it sits in a FEMA flood zone, and it costs nothing to check. This Longview guide covers: locating a parcel on FEMA's map, reading the zone codes, and pairing it with the Texas county CAD map.
Checking the Longview flood zone map step by step
Flood zones come from FEMA's Flood Map Service Center: search an address around Scottsville, then open the map view for that panel. A tract near Scottsville without an address can still be found: zoom in from Interstate 20 then click the parcel area.
The viewer Harrison County publishes
Begin with the Texas county CAD map; it maps every tax parcel around Marshall and Hallsville. For a tract near Waskom, type a street address, an owner's name or a parcel number, and the matching parcel lights up. Out toward Waskom, a pop-up or side panel typically gives the owner of record, acreage on the tax roll, a parcel ID and in many cases the last transfer.
Limits of the parcel data
The acreage figure is an estimate; just a licensed surveyor can set the real lines for a parcel near Uncertain. With a lot near Uncertain, records update in batches, so a deed recorded last month can take weeks to appear.
Beyond the mapped zones
Low-lying fields near Waskom aren't always studied in detail, so ask neighbors about past flooding. Marshy spots near Uncertain can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
Neighboring parcel maps
Harrison County borders Caddo Parish, LA, Gregg County, Marion County, Panola County, and Rusk County, and each of those keeps its own parcel map. A tract near the line by Marshall can be split across two assessors' files, so check the adjacent map too. For acreage around Hallsville, our state page links every neighboring county map for Texas.
Questions to ask before you buy
Ask the listing agent about past flood claims on the property near Marshall; getting a quote early keeps the budget honest.
City limits and county records
Longview lies within Harrison County, Texas, so its parcels are on the county's map. For a parcel near Hallsville, the municipality handles things like zoning, permits and utilities within town limits, but the county runs assessment and recording. Lots just outside the city limits out by Uncertain often follows county rules, not municipal ones.
Reading A, AE and X
Zone AE includes a base flood elevation (BFE), which plain A zones lack; builders around Hallsville design to it. If the land is near Hallsville, a low-risk label isn't a guarantee: according to FEMA, floods happen outside mapped zones too.
Recorded documents worth pulling
The map is an index, not the title: deeds, subdivision plats and easements covering ground around Waskom sit with the County Clerk. In and around Scottsville, have ready the book and page from the tax record to skip a name search.
