These documents are infrastructure utility maps for Ellington Field Air National Guard facility, dated 2020. The five maps illustrate the size and material composition of five critical utility systems serving the installation, with all maps scaled at 1 inch = 190 feet when printed on ANSI E (34"x44") paper.

The Sanitary Sewer map displays gravity mains, service lines, pump stations, and related components constructed of concrete (co), metal (me), and plastic (pl) materials, with pipe sizes ranging from 6 inches to 8 inches. The Storm Drainage map identifies stormwater inlets, outlets, pipes, culverts, and trench drains using similar material designations. The Water Distribution map shows the potable water system including control valves, fire hydrants, fittings, and water mains of 2-inch and 8-inch diameter metal construction, with notation of non-NGB (National Guard Bureau) assets. The Electrical Distribution map depicts overhead primary lines, underground primary and secondary systems, transformers, lighting, switches, and access points serving Building 1289 and adjacent structures. The Gas Distribution map shows the natural gas main distribution network with 2-inch metal piping, control valves, and gas meters serving the installation. All maps include installation boundaries, building footprints, pavement areas, fencing, and watercourse lines for spatial reference, along with standardized material abbreviations and legends for identification of active and abandoned utility infrastructure.
