Cultural Resources Survey for a Joing Task Force Six (JTF-6) Action in Webb, Maverick, and Dimmit Counties, Texas

Abstract

In an effort to aid United States Border Patrol efforts to combat smuggling and illegal immigration in south Texas, road improvements have been proposed along the U.S.-Mexico international border in three south Texas counties by Joint Task Force Six (JTF-6). JTF-6 Operation Number JT513/515/425-98 consists of a single action in Webb, Maverick, and Dimmit counties, Texas. This action includes the repair/upgrade of approximately 211.0 km (131. 1 mi) of existing roads, the construction of roughly 176.7 km (109.8 mi) of new roads (totaling 387.7 km (240.9 mi), the excavation of three borrow pits, the construction of an equipment storage area, two helipads, one airfield, and two base camp areas for this and future JTF-6 rotations. The proposed activities associated with this JTF-6 action are distributed among nine separate project area segments in the Laredo and Carrizo Springs, Texas, Border Patrol sectors. These nine project segments consist of the Rio Bravo, Laredo River Road, Galvan Ranch, Stone Ranch, Swartz Ranch, State Highway 277, Farm-to-Market Road 2644, State Highway 83, and Farm-to Market Road 3338 segments. The protection of the cultural resources falls under the jurisdiction of the U.S. Army Corps of Engineers. Geo-Marine, Inc. (GMI), was contracted to conduct a systematic cultural resources inventory survey of the proposed impact areas.
