Town Council Agenda Date: December 17, 2024
Body
________________________________________________________________________________
Executive Summary
Castle Rock Water (CRW) seeks Town Council approval of a Resolution (Attachment A) approving an agreement (Exhibit 1) with S.J. Louis Construction, Inc., Sedalia Lift Station and Force Main to Plum Creek Water Reclamation Authority Project, for the amount of $633,203.00, plus a 10% contingency, for a total authorization amount of $696,523.30.
The Sedalia Lift Station and Force Main to Plum Creek Water Reclamation Authority (PCWRA) Project will improve water quality, fuel high quality economic development in a key corridor, allow CRW to capture reuse water supplies, create economies of scale, and support existing employers.
This project is to design and build the main wastewater conveyance system for Sedalia and the surrounding area. The project is funded by the American Rescue Plan Act (ARPA) through Douglas County with CRW acting as the Project Manager for the project and eventually owning and operating the system for the benefit of the community. Douglas County has approved the project award and agreement with S.J. Louis Construction, Inc.
The construction delivery method for the project is a Progressive Design-Build method. Phase 1 of the project includes a work product up to 60% design which is the basis for this Agreement. At 60% design, a Guaranteed Maximum Price or a lump sum price is negotiated and CRW has the option to accept either for the completion of the project. A Phase 2 Agreement is then negotiated for final design and construction. This Phase 2 Agreement will need to be approved by Douglas County and by Town Council. The entire project is scheduled to be completed by December 31, 2026.
Notification and Outreach Efforts
Douglas County has posted a news article on their web page about this Highway 85 Southern Corridor Wastewater Project. ToCR has entered into an Intergovernmental Agreement (IGA) with Douglas County for this project.
CRW has developed a stakeholder group that includes key potential customers for the wastewater project. This group is meeting to review all aspects of the project and provide CRW and Douglas County input.
Plans are currently being made with Douglas County and CRW to encourage residents and businesses that are not current stakeholders to participate in the sewer trunkline planning and construction along with hooking up to the system.
History of Past Town Council, Boards & Commissions, or Other Discussions
Castle Rock Water Commission recommended approval of the Amended and Restated IGA with Douglas County for the Highway 85 Wastewater Collection and Treatment System on May 22, 2024.
The Amended and Restated IGA with Douglas County for the Highway 85 Wastewater Collection and Treatment System was approved by Town Council on July 2, 2024.
Douglas County approved the IGA on July 2, 2024.
Discussion
This project will benefit Sedalia residents and businesses by eliminating the need for onsite septic systems for their respective residential and facility wastewater treatment. The reduction of onsite wastewater treatment systems along the East Plum Creek corridor will assist in improving the water quality of East Plum Creek and Plum Creek, a water supply source for the Town of Castle Rock (ToCR).
This project will build a lift station to pump wastewater from Sedalia through a pipeline (forcemain) back to PCWRA. Attachment B shows potential lift station locations and force main routes. Sewer trunk lines and connections to residents and businesses will need to be constructed through potential customer financial inputs and / or system development fees to take full advantage of this project. The key stakeholders (customers) planning to discharge into the lift station for conveyance to PCWRA are the Douglas County School District, CORE Electric, Sedalia Water and Sanitation District water customers, current developers with development proposals in-process with Douglas County.
