Project Description

The applicant requests Use Permit and Design Review approval to construct a new 30-foot-tall wireless communications facility (WCF) on an 400 square foot concrete slab on a lot located in San Anselmo (on the grounds of San Domenico School). The WCF entails building a new 30-foot tall, 17-foot by 17-foot wide at the base and 13-foot wide at the top structures disguised as a water tower structure. Additional facilities associated with the WCF would be located approximately 330 feet from the water tower structure in an 423 square foot fenced area. The two location would be connected via underground cables. The WFC would be setback at least 650 feet from all property lines.

The WCF would include the following: (1) approximately 400 square foot concrete slab; (2) 30-foot-tall structure disguised as a water tower structure; (3) nine 8-foot-tall antennas enclosed within the water-tower portion of the structure; (4) an approximately 423 square feet area enclosed by an eight-foot-tall wood fence; (5) 30 kw backup diesel generator; (6) three backup power/battery cabinets; (7) rack mounted equipment which includes telecom cabinets and equipment enclosures. Various site improvements would also be entailed in the proposed development, including widen the gravel roadway to 12 feet to access the proposed WCF, and general site improvements to implement the proposed project.

Conditional Use permit approval is required for telecommunication facilities under the Marin County Code, Implementation Plan Section 22.62.060(D); and Design Review approval is required pursuant to Marin County Code Section 22.42.010.
