SUMMARY:
I. EXECUTIVE SUMMARY:
Valley Internet is pursuing a use permit to construct and operate a new wireless communications facility consisting primarily of a 50-foot-tall lattice tower and associated equipment within a 1,450 square foot fenced lease area on property located at Assessor Parcel Number 0180-100-010, in an unincorporated area of Solano County.
Pursuant to Section 28.81(E)(2)(a) of the County Zoning Regulations, Planning Commission approval is required for new facilities which are not co-located or grouped.
II. OBJECTIVE:
The proposed project is part of a broader initiative funded by the American Rescue Plan Act (ARPA) to expand access to reliable, high-speed internet in underserved and unserved areas of rural Solano County. This effort aims to improve digital connectivity to support critical services such as telehealth, remote education, emergency communications, and economic development in rural communities.
The project directly supports Solano County’s Strategic Broadband Development Plan, which seeks to close the digital divide, a longstanding challenge that predates the COVID-19 pandemic. Valley Internet, the applicant, has partnered with the County’s General Services Department and has been awarded ARPA funding to assist in implementing this initiative.
This wireless communications facility is one component of a larger network expansion effort. The applicant has submitted an additional use permit application for a similar facility approximately three miles from this proposed project site and has indicated the presence of another tower within the Fairfield city limits. Collectively, these installations are intended to enhance broadband coverage and contribute to the County’s goal of achieving equitable digital access for all residents. The contract between the County and Valley Internet is in place through December 15, 2026 (Attachment B)
III. LOCATION:
The project site is in southern Solano County, within the Cordelia Hills area, approximately 1.15 miles southwest of the City of Fairfield, situated between Interstates 80 and 680. As designated in the Solano County General Plan, the property lies within the Western Hills agricultural region, which is characterized by rolling grasslands, oak woodlands, and elevated plateaus. The region’s steep topography and soil conditions limit its agricultural productivity, making it generally suitable for grazing activities.
The subject property is zoned Exclusive Agriculture with a 20-acre minimum parcel size (A-20). It is currently undeveloped and primarily used for cattle grazing. Access to the site is provided via internal ranch roads that connect to Gold Hill Road.
IV. PROJECT DESCRIPTION
The proposed wireless communications facility consists of a 50-foot-tall, self-supporting lattice tower. The installation will include twelve (12) antennas, two (2) battery enclosures, one (1) network enclosure, and one (1) backup generator, for a total of four (4) ground-mounted equipment cabinets. The facility will also feature a six-panel, ground-mounted solar array, which will provide the power necessary to operate the site independently, eliminating the need for external electrical service. All components of the facility will be located within a 1,450-square-foot lease area. This area will be enclosed by a chain-link fence for security.
Access to the site will be provided via existing internal ranch roads. The property owner holds access easements that permit use by the owner, guests, and invitees, provided such use does not result in a surcharge. Valley Internet, as an invitee, will utilize the access route minimally, limited to the initial construction of the facility and periodic maintenance.
As a self-sustaining, unmanned facility, the project does not require additional utility connections or infrastructure improvements.
V. ANALYSIS
A. General Plan Consistency:
The proposed project is on land designated as Tri-City/County Cooperative Planning Area by the Solano County General Plan (Figure LU-1 Land Use Diagram). The project as designated and conditioned is consistent with the General Plan goals and policies including but not limited to those related to the protection of open space and agriculture.
The facility has been designed to be visually unobtrusive and self-sustaining, utilizing solar power to avoid the need for external utility connections. This approach aligns with the intent of the Tri-City and County Cooperative Plan to preserve open space and minimize infrastructure impacts in agricultural areas.
B. Zoning Consistency:
The subject property is located within the Exclusive Agriculture “A-20” zoning district. This district requires issuance of a use permit to authorize new wireless communication facilities subject to conditional approval by the Planning Commission.
Wireless facilities are required to be of minimum functional height, with additional provisions for co-location. Facilities sited more than ¾ of a mile from a designated scenic corridor are limited to 65 feet in height. A bonus height of up to 20 feet for a maximum of 105 feet is permissible for operators collocating on a single tower.
The proposed project is located approximately 6,500 feet from Interstate 80 and about 10,000 feet from Interstate 680. It lies outside of the ¾-mile designated scenic corridor and has been designed to minimize visual impacts. It remains below the maximum allowable height while maintaining sufficient elevation to provide effective service to the area.
Due to its off-grid design, the facility lacks the capacity to support co-location. It cannot accommodate additional radios or ancillary equipment from other providers, as the limited tower space, structural load capacity, and site footprint restrict expansion. Introducing additional carriers could also result in signal interference, increased maintenance demands, and inconsistent power usage, all of which could compromise system reliability.
As designed, the facility will exclusively support Valley Internet’s equipment. The proposal complies with zoning regulations for new wireless communication facilities located outside scenic corridors and adheres to the 65-foot height limit.
Alternative Analysis
Per Section §28.81(F) of the Zoning Regulations, an Alternative Analysis has been provided as required for any facility requiring a use permit before the Planning Commission. The Alternative Analysis considers alternative locations and designs for the proposed facility, including those alternative sites which would not require a use permit. At minimum, alternatives in the analysis include:
1. Co-location at all existing wireless communication facilities whether in the unincorporated County, a city, or an adjacent county.
2. Lower, more closely spaced wireless communication facilities, and
3. Mounting on any existing non-residential structure within 2-miles of the proposed facility in unincorporated Solano County.
The project proponent has submitted an Alternatives Analysis (Attachment C), which evaluates potential sites within a two-mile search radius, representing the area where a coverage gap was identified. The alternative locations were ultimately deemed infeasible due to a combination of factors, including insufficient line-of-sight coverage, lack of supporting infrastructure, inadequate building height or structural integrity, and the absence of leasing rights.
Design Consistency with the Surrounding Environment
The proposed facility is in a rural setting characterized by rolling grasslands, oak woodlands, and elevated plateaus. Due to the region’s steep topography and soil conditions, the land has limited agricultural productivity and is primarily suited for grazing.
The lattice tower has been carefully sited and designed to blend with the natural environment to the greatest extent feasible. A Visual Impact Study (Attachment D) submitted by the applicant demonstrates that the tower’s visibility diminishes significantly with distance from publicly accessible viewpoints. The facility will be centrally located within a 508.80-acre parcel, where natural features such as valleys, ridgelines, and mature oak trees help further screen the structure from view. The nearest residence is located over 0.5 miles to the west and more than one mile to the east.
The lattice tower design was selected for its ability to accommodate multiple antennas at lower heights compared to monopoles, while also offering reduced visual impact due to its open, non-reflective structure. Its transparency allows it to visually recede into the landscape, especially at greater distances.
In accordance with §28.81 of the Zoning Regulations, which encourages stealth design elements, the applicant has proposed a lattice structure that naturally integrates with the surrounding environment and minimizes visual intrusion.
Radio-Frequency Exposure Report
In accordance with Section 28.81(H) of the Zoning Regulations, the project proponent has submitted a Radio Frequency (RF) Environmental Evaluation Report demonstrating that RF emissions from the proposed facility, when combined with emissions from nearby facilities, will remain within the exposure limits established by the Federal Communications Commission (FCC).
A Radio Frequency Site Compliance Report (Attachment D), prepared by SiteSafe, was provided to evaluate RF exposure levels associated with the proposed wireless communication equipment. The report references the FCC’s Maximum Permissible Exposure (MPE) limits, which define acceptable exposure thresholds for both the public and occupational settings.
The analysis concludes that there are no modeled RF exposure levels on any accessible ground-level walking or working surfaces that exceed FCC limits. To ensure ongoing compliance, the site will be required to include appropriate RF notice signage, Network Operations Center (NOC) contact signage, and maintain locked or restricted gate access.
C. Airport Land Use Compatibility
As seen in the Travis Air Force Base Land Use Compatibility Plan, the project is located within Compatibility Zone “D” which prohibits hazards to flight and requires Airport Land Use Commission (ALUC) review for objects taller than 200 feet above ground level (AGL). At 50 feet Above Ground Level (AGL) this project is consistent with the ALUC guidelines and does not require further review.
ENVIRONMENTAL ANALYIS
D. Environmental Determination:
The Department of Resource Management is recommending that the project be exempt from the California Environmental Quality Act (CEAQ) pursuant to CEQA Guidelines Section 1503, New Construction of Conversion of Small Structures. This exemption consists of structures, and installation of small new equipment and facilities or structures, and installation of small new equipment and facilities in small structures. The guidelines state examples including, but not limited to, utility extensions and appurtenant structures.
The project consists of a new cellular tower and associated equipment, contained within a 1,450 square foot lease area. There is no evidence in the record that the project would result in substantial, or potentially substantial, adverse environmental changes to any of the physical conditions within the area, including land, air, water, minerals, flora, fauna, ambient noise, or objects of historic or aesthetic significance. It has been determined that the project is not in an environmentally sensitive location, is not on a hazardous waste site, will not cause substantial change in the significance of a historical resource, and will not result in damage to scenic resources within a scenic highway. Staff therefore recommend that the project be found categorically exempt from CEQA under CEQA Guidelines Section 15303.
The County further finds that the project is not subject to any exceptions to the categorical exemptions as set forth in CEQA Guidelines Section 15300.2:
1. Location. The project will not be in an environmentally sensitive area.
2. Cumulative Impact. A review of the subject property and surrounding parcels shows no active projects that would result in cumulative environmental impacts. The exception for cumulative impacts does not apply.
3. Significant Effect. The proposal to entitle a wireless facility does not involve unusual circumstances or environmental conditions that would distinguish it from similar projects. The exception for significant effects does not apply.
4. Scenic Highways. The project will not damage scenic resources (e.g., trees, historic buildings, or rock outcroppings) within a state-designated scenic highway. The facility will not expand in a way that would require removal of scenic resources. The exception of scenic highways does not apply.
5. Hazardous Waste Sites. The project site is not listed pursuant to Government Code Section 65962.5. The exception for hazardous waste sites does not apply.
6. Historical Resources. The project is not located on a historic resource site and will not result in substantial adverse changes to historical resources. The exception of historical resources does not apply.
E. Good Neighbor Policy
On April 9, 2024, the Board of Supervisors adopted a Good Neighbor Policy, which encourages project proponents to engage with the community early in the process to promote transparency and foster public dialogue prior to formal public hearings.
For this project, the applicant chose not to participate in the Good Neighbor Policy outreach process.
F. Public Notice
Consistent with Sections 28.106 and 28.04 of the Solano County Code, a public hearing notice was published in the Daily Republic at least 15 days prior to the public hearing. In addition, all property owner’s within ½ mile of the project site received written public notice.
