Craig & Gould Infrastructure Improvements

Updated May 3, 2021

Castle Rock Water and Castle Rock Public Works are planning infrastructure improvements in the Craig and Gould North neighborhood to address stormwater flows, upgrade street pavement, and replace aging water and sanitary sewer mains as appropriate. The project will reduce flooding hazards, unnecessary utility disruptions and improve traffic and pedestrian use of the right-of-way. This infrastructure will be upgraded to meet current design criteria standards and will be similar to improvements completed in the Craig and Gould South neighborhood in 2005. 

Project Scope

With input from residents and considerations from Castle Rock Water and the engineering design firm, infrastructure designs have been finalized. View a map of the overall project improvements

  • 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 ADA 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 designed and 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 under 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 will complete 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.


Final design engineering, permitting and property acquisition are currently in progress. The project is tentatively scheduled for construction to begin in the summer of 2021, and continue for 12 months. 


AECOM Technical Services, Inc. has been awarded the contract for engineering design, surveying, permitting and geotechnical services for upgrading the streets, alleys, storm drainage, water and sanitary sewer infrastructure in the Craig and Gould North neighborhood. 

Cost of the project for design and construction is estimated at $7.9 million.
