The Project includes the construction, operation, and maintenance of a proposed 1.5 million gallon welded steel water reservoir and approximately 5,816 linear feet (1.1 miles) of 12-inch diameter ductile iron water transmission pipeline along the east side of Irwin Road that would connect to existing pipeline located at the intersection of Irwin Road and Gabilan Street. Approximately 4,000 linear feet (0.75 miles) of the Project is located within land owned by the County of San Bernardino and 1,800 linear feet (0.34 miles) of the Project lies within Bureau of Land Management (BLM)-lands. The reservoir would be constructed on a 1.03-acre site that would require permanent right-of-way from BLM.
