Title
Resolution of the Town Council of the Town of Castle Rock Approving the Renaming of South Interstate 25 Road to South Wilcox Street [from Plum Creek Parkway to Crystal Valley Parkway]
Body
________________________________________________________________________________
Executive Summary
Staff is seeking Town Council approval for renaming of South Interstate 25 (East Frontage Road) to South Wilcox Street. This renaming will establish name continuity from Plum Creek Parkway to Crystal Valley Parkway. Establishing a continuous South Wilcox corridor within the Town limits will significantly improve navigation for emergency responders, enforcement boundaries, delivery services, residents and future land development activity along the corridor.
Additionally, during the design process of the Crystal Valley Interchange, it was recognized that using a single street name on the identification and wayfinding signs associated with the new intersections, in particular the roundabout on the east side of I-25, would reduce initial construction costs, as well as ongoing maintenance and future replacement costs.
The proposed street name and address changes will not take effect until after the annexation of the roadway is finalized. A resolution for the annexation of the roadway is scheduled for Town Council consideration in the near future.
Discussion
Associated with the construction of the Crystal Valley Interchange, in 2023 the Town entered into an Intergovernmental Agreement (IGA) with Douglas County (County) that transferred ownership of parcels purchased by the county for the sole purpose of constructing the interchange. With these conveyances and the requirements of the IGA, the Town assumes full responsibility for the maintenance and operation of the entire section of roadway.
Staff is currently in the process of annexing the conveyed property into the municipal boundaries and under Town jurisdiction. As part of this process, Town staff is initiating the formal street renaming to improve street name continuity within the Town limits.
The current roadway is named South Interstate 25 Road from Crystal Valley Parkway north to the southern boundary of the Town which is located near the car dealerships. There currently is no distinctive signage marking the transition from South Wilcox Street to South Interstate 25 along this corridor.
When a street name change is proposed within Town limits, the Town of Castle Rock initiates the process by submitting a formal referral request to Douglas County Planning and Addressing. This referral identifies the proposed street name revision and any required address changes.
Douglas County, as the authority responsible for address assignment, reviews the corridor to ensure all updated addresses are sequential, consistent with the regional address grid, and compliant with County addressing standards. Upon Douglas County’s approval, the Town may proceed with public notification efforts, Council review, and any required annexation actions. Following Town Council approval, Douglas County finalizes and records the official street name and assigns the new addresses, which then become effective on the recorded date.
The renaming to South Wilcox Street will require 61 properties to change their addresses as seen on the attached map.
Following the Town policy on street name change, staff coordinated with the Town’s Community Relations team and prepared a notification letter requesting public feedback via a website link. The letter was mailed to all affected addresses on October 9, with the comment period ending on October 31. The Town received three comments, all in favor of the street name change, citing that it would help reduce confusion.
In addition to the Town’s outreach efforts, Douglas County Planning & Addressing will provide further notification in accordance with their established policy. A notice of pending address changes will be sent to all affected residents and businesses shortly after the start of the new year, offering an additional opportunity for property owners to provide comments or request clarification. Following Town Council’s Second Reading for the roadway annexation, Douglas County will issue the final address change letter. The updated addresses will become official upon formal recording of the new street name.
Budget Impact
The budget impact of the proposed street name change is not yet known. A total of 61 addresses would be affected by the change, including 1 church, 55 businesses, and 5 residences. While the Town does not have an established policy regarding reimbursement for address-change expenses, providing assistance may be considered a neighborly and supportive approach given the community impact. On past projects, including the North Meadows Extension, residents that experienced a change to their address as a result of a street name change were given $50 each to offset any costs associated with the re-addressing of their property.
Typical costs for residents are relatively minimal, generally $50 for updated driver’s licenses, checks, and incidental items resulting in an estimated total of approximately $250 for the five affected residences. The church is anticipated to incur higher expenses, estimated at $1,500, primarily for signage and printed materials. Businesses are expected to bear significant impacts. Using an average cost of approximately $800 per business covering signage, vehicle decals, website updates, and printed collateral, the total expected cost for all affected businesses is approximately $43,250. Together, these impacts result in a preliminary community-wide estimated cost of $45,000. Should reimbursement be requested, such requests will be reviewed and considered on a case-by-case basis. This expense was anticipated during budget development, and Finance has confirmed that sufficient funds are available to cover the cost.
Additional local street signs required for the name change will be fabricated and installed in-house by the Town’s Signs and Markings Department, minimizing external costs. This cost falls within the Public Works Department’s budget.
Staff Recommendation
This item was reviewed with the Public Works Commission at their December meeting. They formally recommend that Town Council direct staff to complete the street name change to South Wilcox Street. They also recommend that Town Council direct staff to work with individual property owners on a case-by-case basis to assist with reimbursement requests, and that the total reimbursements should strive to stay under $45,00
