Aurora City staff briefed the council on May 20 and advanced several intergovernmental agreements to address stream restoration, erosion and flood control in the Cherry Creek watershed and Westerly Creek near Stanley Marketplace.
Jess Kopier, manager of environmental compliance services, described a proposed IGA for Cherry Creek Reach One. She said the project addresses erosion, water‑quality improvements within the reservoir and protection of Aurora’s Ramart raw water lines. “The cost associated with this agreement would be Aurora's anticipated contribution under this for 2026 would be $1.1 million,” Kopier said, adding that federal and state funds are expected to supplement the total project cost of about $3.6 million.
Andrea (staff) summarized an amendment to a Mile High Flood District IGA for stream restoration at Arapjo Road upstream of Reach One. Aurora’s historical cost share is roughly 20%; the current amendment was presented as a $400,000 Aurora contribution to complete design work, with possible future amendments and construction contributions to be determined based on benefit allocation.
Staff presented a seventh amendment for the 22nd Avenue/Westerly Creek outfall (area by Stanley Marketplace) that would add regional drainage, flood control, water‑quality and trail improvements. The district’s contribution for the amendment was presented as $250,000 and Aurora’s as $560,000; staff noted prior contributions by the private partner (Pros) totaling about $3.4 million in earlier cycles.
Council Member Lawson asked whether Stanley Marketplace or developers contributed to the improvements; staff said there had been shared funding over time but they would follow up with historical details and confirm developer contributions.
The items were advanced from consent with council members indicating support to move the items forward; no roll‑call vote tally was recorded in the transcript. Staff said some construction‑phase contributions remain to be negotiated and that future amendments may set final shares.
Next steps: staff will return with confirmation of historical developer contributions and any construction‑phase funding details if required.
