Craig & Gould Infrastructure Improvements
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.
With input from residents and considerations from Castle Rock Water 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 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 Interstate 25, ultimately discharging to East Plum Creek. Additionally, opportunities for installing detention and water quality features will be explored to the extent feasible.
- 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.
Final engineering design is currently underway and the project is scheduled for construction to begin late summer 2020.
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 $6.6 million.
