Document Description
The project site is located south of West Temple Avenue and west of Bonita Drive within the southeastern portion of the Mt. SAC Campus in the City of Walnut, Los Angeles County, California. The project proposes to construct a new self-supporting 100-foot-high communication tower and related improvements, including outdoor equipment and a 6-foot-high chain-link fence. The proposed communications tower would replace the existing 40-foot-high tower, at a location slightly southeast of the existing tower on Reservoir Hill. The existing tower site consists of a power pole, concrete pad, chain-link fence, radio cabinet, steel pole with concrete base, transformer, power sub-panel, and telco cabinet. Removal of these facilities is included as part of the proposed project. A gravel pad, and two existing tanks with concrete support are also located on the site. The new 100-foot-high self supporting tower is comprised of a pier foundation, one JamPro-JMPC single bay antenna, and three Browning-BR6155 antennas. The proposed tower would support 2-way communication for the campus associated with the Emergency Operations Center (EOC), the Altertus campus emergency mass notification system, and broadcast transmission for the campus radio station, 90.1 FM Mt. Rock.
