B. 
Commercial communication facilities in industrial or commercial zoning districts that are not over seventy-five feet above ground level are not subject to the requirements of this chapter.
C.

(Ord. CS 600 §1, 1995)
Communication facilities, including communication towers, antennas, microwave dish antennas, and equipment shelters, may be permitted in any zoning district subject to approval of a use permit or staff approval permit by the appropriate authority as follows:
A. 
Planning Director—Any communication facilities that meet the siting standards of this chapter are subject to a staff approval permit, pursuant to Chapter 21.100. Prior to action by the planning director on communication facilities in the A-2 (General Agriculture) district, surrounding property owners and appropriate agencies shall be notified as provided in Section 21.96.040(A).
B. 
Planning Commission—Any communication facilities, including ancillary equipment buildings, that do not meet the siting standards of this chapter are subject to issuance of a use permit by the planning commission, pursuant to Chapter 21.96.
(Ord. CS 600 §1, 1995)
A. 
General Standards.
The following standards apply to all communication towers, antennas, microwave dish antennas, and equipment shelters:
1. 
The facility shall be located in any area other than a residential district or historical site (H-S) district or an area designated Residential on the General Plan map.
2. 
The facility shall meet all yard requirements for structures in the particular zoning district in which it is located.
3. 
The communication facilities shall not significantly displace or impair agricultural operations, including crop dusting, on the subject parcel or surrounding parcels.
4. 
Identification signs, including emergency phone numbers of the service provider, shall be posted at all tower and equipment sites.
5. 
All unused or obsolete towers and equipment shall be removed from their respective sites within six months after their operation has ceased, at the landowner's expense.
B. 
Siting Standards for Communication Towers.
1. 
The tower shall be a monopole design unless the planning director determines that it would not be visible to the general public, in which case a lattice tower design may be approved.
2. 
The height of the tower shall not exceed one hundred thirty feet above ground level.
3. 
The tower shall be located a distance equal to at least twice the height of the tower from residential structures on adjoining properties.
C. 
Siting Standards for Antennas, Including Microwave Dish Antennas.
1. 
Antennas may be mounted on communication towers, water towers, billboards, building facades, or other structures if they are screened or mounted in an aesthetically acceptable manner. Both the antenna and any screening structure are subject to all applicable building code requirements including building structure and wind load integrity.
2. 
The overall height of the antenna, including mounting hardware or base, shall not exceed ten feet above the height of the building or structure on which it is mounted, or the height of the building plus the horizontal distance from the antenna to the edge of the roof, whichever is greater.
D. 
Equipment shelters shall be a maximum of six hundred square feet in size.
(Ord. CS 600 §1, 1995)
To minimize the number of communication towers throughout the county, service providers shall employ all reasonable measures to co-locate their antenna equipment on existing towers prior to applying for approval of new towers. All county agencies and service providers shall be encouraged to permit co-location of microwave dishes and cellular facilities on appropriate existing structures subject to reasonable engineering requirements.
(Ord. CS 600 §1, 1995)
Decisions on use permits or staff approval permits may take into consideration the aesthetic impact of the proposed microwave dish antennas and/or communications facilities and may include conditions of approval for the purpose of reducing the visual impact of the antenna and/or facility as seen from adjacent properties or for the purpose of reducing the potential of safety or health hazards. Such conditions may include, but are not limited to, partitions, screening, landscaping, mountings, fencing, height of antenna, and site location within parcel.
(Ord. CS 600 §1, 1995)
In addition to the requirements listed herein, cellular communication facilities are subject to all other applicable regulations and permits, including those of the Public Utilities Commission (PUC) of the state of California and the Federal Communication Commission (FCC).
