Title
Update: Wireless Communication Facilities
Body
________________________________________________________________________________
Executive Summary
In 2018, the Town’s Wireless Code was revised to align with updated State and Federal regulations. Additionally, processes for handling applications for new wireless communication facilities (WCFs) were streamlined. As the Town grows, so do the demands for cellular coverage in the community. Providers, driven by market demand, are responsible for determining technology, location and timing for installation of new WCFs.
The following discussion provides a brief update of the Town’s approach to handling WCFs in the community, plus information regarding existing and proposed wireless communication facilities within Town boundaries.
Discussion
Background
Town Council, in 2018, approved updates to the Town’s Wireless Code. In addition to ensuring compliance with Federal and State regulations, updates to the wireless code provided accommodation for small cell technology in the right-of-way. Along with compliance with the updated Code, wireless providers utilizing Town right-of-way will be required to enter into a Master License Agreement with the Town that has additional standards and requirements for design, operations and fees.
Wireless Communication Facilities (WCFs) include macro and small cell technologies. Macro facilities are larger scale sites, typically stand-alone towers or rooftop locations, which provide larger scale cellular coverage. A small cell facility is defined as a wireless facility in which an antenna would fit into an enclosure that does not exceed three cubic feet in volume. These facilities are most commonly placed on light poles or traffic signals. Small cells are typically utilized to increase the capacity of an existing coverage area rather than expanding the size of the coverage area. More information about small cell WCFs can be found in Attachment A.
Town Wireless Communication Facilities
When a provider requests installation of a new WCF within Castle Rock, approval can be either administrative or by Council action dependent on the required land use approval process for the specific wireless communication facility. For WCFs located on Town property (outside of right-of-way), the Town will act as a property owner first and land use regulator second. The Town acting as the property owner, rather than the land use regulator, has much more discretion in making a decision about locating wireless communication facilities on a specific Town property. Site locations within Town-owned right-of-way go through a permitting process managed by the Town’s Development Review Team.
Master License Agreements (MLAs) provide a base agreement with providers that stipulate standards for design, operation, applicable fees, and expedite the application process for small cell locations in the right-of-way. The Town currently has three MLAs in place with Verizon and infrastructure providers Zayo Group and SQF (Tilson Infrastructure).
There are currently 33 WCFs within Town boundaries including 10 macro and 23 small cell facilities. As of August 22, 2025, there are 14 small cell sites installed within the public right-of-way. There are an additional two small cell sites within the public right-of-way approved but the timing is unknown for the installation of the proposed infrastructure. Town Council approved a T-Mobile wireless communication facility that is an addition to the pool house at Butterfield Park on March 19, 2024. Construction is anticipated sometime in 2025. However, once the Town approves the addition of a new WCF, the actual construction timeline is determined by the provider.
Town staff is prepared and ready to assist wireless providers with infrastructure applications and will continue to follow approved Code requirements to ensure timely responses to all applications and safe construction of any approved wireless site. Since 2020, the Town has received 46 applications for wireless infrastructure including updates to existing infrastructure (such as antenna replacements) or new cell sites. The following table summarizes the applications by status with counts shown by the year of the application.

Table 1: 2020 – 2025 (YTD) WCF Application Status. Dates are based off when application was received, not final decision.
Verizon has been installing small cell sites within the public right-of-way. They currently have 16 approved locations, 14 of which have been installed. There are no further sites currently under review.
Tilson Infrastructure has submitted 13 small cell applications currently under review. If approved, these sites will be used by T-Mobile. Based on discussions with Tilson and its consultants, the company anticipates building approximately 55 small cells across the Town, supported by about 13 miles of new underground fiber.
Town staff has conducted a pre-application meeting for a proposed new cell tower location at Fire Station 152 to serve the Crystal Valley area. If the applicant chooses to move forward, the project will require public hearings before Planning Commission and Town Council.
Town staff is ready and available to assist wireless providers to work through all aspects of permitting and construction.
Staff has developed a map that is available at https://www.crgov.com/cellsites to show locations of current and proposed WCFs. A sample of this map is shown below.
While the Town has little control over the wireless infrastructure in Castle Rock due to federal laws and market forces, staff continues to monitor cell site applications in the community. Staff will continue to ensure that infrastructure is permitted and constructed properly according to Town procedures. Periodic updates will be provided in the future in an effort to keep Town Council apprised of any updates and changes regarding cell site in Castle Rock.
Conclusion
