Document Description
Coastal Development Use Permit to authorize construction and operation of a 67 ft. tall “monopine” (a monopole cell tower disguised as a pine tree) tower with various appurtenant equipment and ground equipment including a 30kw generator, 190 gallon fuel storage tank, one (1) GPS unit, twelve (12) antennas (3 per sector), 24 Remote Radio Units (RRUs), four (4) surge suppressors, two (2) future 4-foot microwave dishes, and trenching for a Power/Telco (fiber) to site location. The facility will operate 24 hours a day 7 days a week. Maintenance workers will visit the site approximately once a month. The generator will be turned on once a week for 15 minutes for maintenance purposes. Maintenance operations are limited to the hours of 8:30am to 4:30pm and shall occur only on weekdays (Monday through Friday). There will be minimal noise from the standby generator. The tower will be built to provide co-location opportunities for future carriers and/or public safety entities. Associated improvements to the subject parcel include trenching for power/telco (fiber) to the wireless communications tower facility, which will require approximately eight (8) cubic yards of earth to be moved. Trenches are 36 inches deep and 12 inches wide, and approximately 70 feet in length. A 20 ft. wide easement of approximately 220 ft. in length is proposed. In total, approximately 35 cubic yards of earth will be displaced. AT&T is participating in a Federal Government funded project called Connect America Fund, the goal of which is to provide under served areas throughout the United States in general and throughout Mendocino County with hi-speed broadband internet, as well as fill a significant mobility coverage gap in the service area. The proposed “monopine” will be located within an 1,800 sq. ft. fenced compound. Elevation of the project site is approximately 170 feet above sea level, giving parcels within the surrounding community and State Route 1 increased potential for line of site to the tower. Up to two (2) carriers will be able to co-locate on the tower, increasing cellular coverage for the community of Caspar, travelers, and emergency services and first responders. Additionally, the facility will provide FirstNet services for First Responders.
