mount CMRS antennae. Examples would include manmade trees, clock towers, bell steeples, light poles, silos, existing utility poles, existing utility transmission towers and other similar alternative design structures". 17.08.047 Building mounted CMRS facility: "means any facility where the CMRS antennae are proposed to be mounted on an existing or proposed building, and excluding any facility meeting the definition of a freestanding CMRS facility or the definition of an alternative tower structure". Staffs determination is that the CMRS facility meets the definition of a building mounted facility as the antennae are not mounted within, or camouflaged or concealed by a structure within the definition of ATS. As a building mounted facility in an AO zone district, the facility is required to secure authorization of a Special Review Use as defined in Section 17.40 of the LMC (SRU). SUMMARY OF PROPOSAL / STAFF COMMENTS: On May 9, 2008, AT&T Mobility submitted an application to place nine (9) roof mounted, unscreened, antennas on the roof of the existing office building located at 315 South Boulder Road. The applicant proposed a series of roof mounted antennae array with all support mechanical equipment to be located in the basement of the office building. Staff worked with AT&T to revise design elements of the request to incorporate screening of the antennae. Screening was requested given the proximity of the antennae to the roof parapet and therefore the resulting visibility from the adjoining property lines. Relocating the antennae with an increased setback from the parapet was not possible given the location of existing roof top HVAC equipment. The height of the existing building is 26'6". The overall height of the mounted antennae is approximately 32', which is less than maximum building height of 35'. The Planning Director, based upon compliance with CMRS design standards set forth in Section 17,42.030, issued an administrative approval for the building mounted CMRS in June of 2008. Based upon that administrative approval the applicant submitted a building permit application in July of 2008, and received an approved building permit in August of 2008. The facility was constructed in accordance with approved plans and finaled out by the Building Safety Division on October 30, 2008. Based upon receiving a call from a tenant of 315 South Boulder Road, staff reviewed the administrative approval and determined that the administrative approval had been issued in error. As noted in the Background discussion, a building mounted CMRS in an AO zone district is required to be processed as a Special Review Use. Upon this determination that an error had been made, staff proceeded to establish required public notice for the SRU hearing and notified the applicant and the owner as such. CMRS Design Standards Section 17.42.030 of the LMC, defines design standards applicable to all CMRS facilities as well as those that are specific to roof mounted panel antennae. Under general standards, facilities are to be designed so as to be compatible in color, texture, 3
