Getting into the Texas county CAD map

What the map covers, from Marshall to the back roads
Marshall is the county seat, and other towns on the map include Hallsville, Longview, Scottsville, and Uncertain. Out in the countryside, Elysian Fields, Gill, and Harleton appear as small knots of lots along the road network. Harrison County was created in 1842 and takes its name from Jonas Harrison. The county's land area is about 900 square miles, and the Census Bureau estimated 70,895 residents there in 2023. Neighborhood lots cluster near Hallsville, while the countryside toward Karnack still holds larger parcels. Public land in or near the county, including Caddo Lake National Wildlife Refuge, changes how nearby private land sells.
Reading property lines on the Harrison County plat map
On rural tracts near Karnack, the parcel lines can drift from the fences on the ground, sometimes by more than a few feet. Texas rural land is described by original survey and abstract number, not sections and townships, and the Harrison County appraisal map usually shows the abstract lines. If a neighbor's fence near Longview and the map disagree, neither one is proof. A survey is.
The Harrison County economy in brief
Federal business data for 2022 shows 1,399 establishments in the county, with retail trade, other services, and professional and technical services at the top of the list. The local economy leans harder than average on oil and gas extraction, support activities for mining and drilling, and pipeline transportation. For land near Longview, the deed history matters as much as the map: minerals may belong to someone else entirely. Keep that in mind when you compare parcels in Harrison County: who works here shapes what land sells.
Behind the map: land records in Harrison County
Behind each Harrison County parcel is an assessment by the appraisal district and a deed recorded with the county. Property values in Harrison County come from its appraisal district, a separate political subdivision with its own board that sets one value per property for every local taxing unit. If you need a plat for a lot in Hallsville, look for the plat book and page or the subdivision name in the parcel record, then request that document from the recording office.
