Craig and Gould Infrastructure Improvements

Castle Rock Water and the Public Works Department are completing infrastructure improvements in the Craig and Gould North neighborhood to address stormwater flows, upgrade street pavement, and replace aging water and sanitary sewer mains. The project will reduce flooding hazards and improve traffic and pedestrian use of the right-of-way. Infrastructure is being upgraded to meet current design criteria standards and will be similar to improvements completed in the Craig and Gould South neighborhood in 2007.

Project scope

With input from residents and considerations from Castle Rock Water, the Public Works Department and the engineering design firm, infrastructure designs have been finalized. 

  • Streets - Existing streets will be reconstructed to current residential design criteria, with the addition of curb and gutter, new asphalt pavement, dedicated on-street parking, signing and striping, and profile grade improvements where feasible. Also, paved sidewalks, crosswalks and Americans with Disabilities Act compliant ramps will be installed to facilitate pedestrian movement in the neighborhood.
  • Storm Drainage - The neighborhood currently lacks a modern storm drainage collection system and is susceptible to localized flooding during storm events. A new storm sewer system will be constructed in conjunction with the street improvements to safely and efficiently capture storm flows in the area. An outfall system will then convey these flows along Sixth Street, under the Union Pacific Railroad and connect to the existing storm sewer under Wilcox Street.
  • Water and Sanitary Sewer - Partial improvements to the existing water mains and sanitary sewer mains in the neighborhood have been implemented in the past as necessary. This project is completing upgrades to the remaining portions of these systems before they become critical, taking advantage of the street and storm sewer construction to minimize inconvenience and disruption to residents. Water service connections and sanitary sewer laterals will also be replaced where new mains are installed.

Access and disruptions

Road closures and restricted driveway access will be necessary, and street parking will be unavailable within the work zone. Detours for the public will also be necessary, but local access for residents at all times will be a priority. Traffic control plans from the contractor have been approved by the Public Works Department to ensure no disruptions to emergency or other services occur.

Temporary disruptions to water services will occur periodically throughout the project as necessary to complete the tie-ins for new water mains and service lines. Disruptions to sanitary sewer services will also occur at some properties when individual service lines are connected to the new sanitary sewer mains. To minimize any inconvenience, affected customers will be given advance notice, typically a minimum of 48 hours, when these disruptions are planned. Services will be disrupted for approximately four to six hours, for each effort.

Please plan to set water aside for drinking and sanitation purposes (for example, fill a bathtub with some water and use a bucket to transfer water to the toilet for flushing) during the temporary water disruptions. If you notice any air, sediment or discoloration in your waterlines after the shutdown, run cold water from the furthest faucet in the house, and from several faucets, to clear things up.


November 2021 through November 2023


AECOM Technical Services, Inc. completed the engineering design, surveying, permitting and geotechnical services for upgrading the streets, alleys, storm drainage, water and sanitary sewer infrastructure. JBS Pipeline, LLC is the construction contractor.

The cost of the project for design and construction is estimated at $8.7 million.

Oct. 6, 2023

We are in the final stages of completing the Craig and Gould Infrastructure Improvement project. As you all know, the project has experienced numerous challenges. The weather in May and throughout the summer has delayed final completion.  Progress has been slow, but we are working with the contractor to finalize landscaping, driveways, and damaged or incomplete elements of the project. We are continuing to conduct onsite engineering surveys to address these outstanding issues.

The Craig and Gould North construction was originally scheduled from November 2021 through August 2023. Due to the weather, final completion has been pushed to the end of November. Again, final completion is dependent upon weather. Please, know that the Town is doing everything in our power to reach final completion as soon as possible. We are anticipating that concrete, paving and landscaping crews will be working diligently in the next few weeks and remain dedicated to the project until finalization.  

Thank you again for your patience and understanding as we bring this project to closure.  Please reach out to us directly if you have any concerns or issues via email.
