This site is 7.4480 acres with approximately 40 small slabs of concrete, possibly an old mobile home community.  There are no buildings, a couple small remnants of old fencing, one large tree and multiple small trees.  There is one well, but it is unknown whether or not it is septic.  There are two large sink holes approximately 4 feet in diameter with one having two pipes that empty into it.  There are multiple wires protruding out of the ground throughout the property next to the concrete slabs.  There is a small road that runs along each side of the property (see Map 3).  There is a drainage ditch and multi-family housing currently being built that borders the northwest end of the site.  A school on the northeast end with a single-family housing subdivision on the southeast.  A shopping center including a car repair shop to the west and a gas station on the southwest ends of the site.  The entire site is approximately 0.15 miles in length.

There is evidence of hazardous waste disposal of old oil filters and discarded tires from the car repair shop.  There is discarded building material on the site from the new multi-family development, as well as, various types of trash from people walking through the site.  There is an underground storage tank at the gas station which is located on the corner of Bandera Rd. and Huebner Rd.
