§ 88-24.406. Location requirements.

Except as otherwise specified in Sections 88-24.402 and 88-24.404, the location requirements of this section apply to all facilities in all zoning districts:

(a)

Collocation Encouraged. The collocation of facilities with existing or proposed collocation-eligible facilities is encouraged.

(b)

Proximity of Towers. No new tower may be located within one thousand feet of an existing tower, unless the zoning administrator finds both of the following:

(1)

The cumulative visual and aesthetic impacts of the tower will be less than significant with or without the incorporation of mitigation measures identified during the California Environmental Quality Act environmental review process for the tower.

(2)

The existing tower is not a collocation-eligible facility, or collocation is not otherwise possible.

(c)

Avoiding Impacts to Ridges, Scenic Ridges, and Peaks.

(1)

No facility may be located on a ridge or peak unless the facility is required to close a significant gap in coverage. The zoning administrator will determine whether the facility is required to close a significant gap in coverage based on information provided by the applicant in accordance with subsection 88-24.604(a)(5). If it is feasible to close the significant gap in coverage by collocating a new facility on an existing facility on or near the ridge or peak, the new facility must be collocated. If it is not feasible to close the significant gap in coverage by collocating a new facility on an existing facility on or near the ridge or peak, in its application for a permit under this chapter the applicant must explain why collocation is infeasible.

(2)

Notwithstanding anything to the contrary in subsection 88-24.406(c)(1), no facility may be located within fifty horizontal feet of any ridge or peak within the Mount Diablo area, or within fifty horizontal feet of any scenic ridge located in a non-urban area, unless the zoning administrator finds that the facility will not result in significant visual or aesthetic impacts with or without the incorporation of mitigation measures identified during the California Environmental Quality Act environmental review process for the facility. No facility may extend above the height of a ridge or peak within the Mount Diablo area, or above the height of a scenic ridge in a non-urban area, unless the zoning administrator determines that an extension of the facility above the ridge, peak, or scenic ridge will not result in significant visual or aesthetic impacts.

(d)

Setback Requirements. A facility that is used for AM, FM, international, or television broadcast service, or that receives television signals for processing and distribution over a cable network (a cable "headend" facility), must meet the setback distance that is the greater of: the setback requirement that applies within the zoning district in which it is located; or a distance equivalent to one hundred ten percent of the height of the facility. All other ground-mounted antenna support structures or towers must meet the setback requirements that apply in the zoning district where the facility is located.

(e)

High-Visibility Facilities. A high-visibility facility must be located within the facility site at a location that the zoning administrator finds will have the least visual and aesthetic impacts to the surrounding lots. If a building exists on a lot, no high-visibility facility may be located on the lot between the face of the building and any public street, bikeway, trail, or park.
