Body
________________________________________________________________________________
Executive Summary
Castle Rock Water is seeking Town Council approval of a Resolution (Attachment A)
to extend the Services Agreement with AECOM Technical Services, Inc. for the Craig and Gould North Infrastructure Improvements Project through September 30, 2023. A purchase order was authorized for these services on December 15, 2020 in the amount of $501,459 and the balance of funds will be carried over into 2023 to cover the remaining cost under this agreement. Construction is currently underway and approximately 75% complete with an anticipated completion date of June 1, 2023.
Notification and Outreach Efforts
Town staff will continue with community outreach efforts to keep impacted property owners informed of progress and disruptions through the duration of construction. Project details and updates are also provided on the Town website,CRgov.com. A community celebration is tentatively planned for May 2023 to express appreciate to those residents and businesses impacted by this work. More information on this event will be communicated to the community and Council once it becomes available.
History of Past Town Council, Boards & Commissions, or Other Discussions
The Craig and Gould North project was last presented to Town Council on December 20, 2020 at which the time Council awarded the original agreement to AECOM.
Discussion
This neighborhood has had a history of concerns including flooding of private property, water main breaks and sanitary sewer backups. This project will reduce flooding hazards, unnecessary utility disruptions and improve traffic and pedestrian use of the right-of-way. This project will implement infrastructure upgrades similar to those previously completed in the Craig and Gould South neighborhood in 2005 (see Attachment B). Specifically, the proposed improvements include:
• 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.
The original agreement with AECOM Technical Services, Inc. terminated on December 31, 2022. An extension is needed through September 2023 to complete the scope of work.
Budget Impact
