Lone Tree Council approves 17-acre RidgeGate project anchored by King Soopers Marketplace

Lone Tree City Council approved a development plan for a new King Soopers Marketplace in the RidgeGate community, clearing the way for a large retail anchor on a 17-acre parcel east of Interstate 25 at RidgeGate Parkway. The project calls for a 123,000-square-foot grocery marketplace, a gas station and six stand-alone commercial buildings, positioning the site between RidgeGate Parkway eastbound on the south and RidgeGate Parkway westbound on the north.

Developers have said construction is anticipated to begin in early 2026, with King Soopers and other shops projected to open in 2027. A separate report lists a summer 2026 opening for a new King Soopers, a date that is not explicitly tied to the RidgeGate site in that account and creates a timing discrepancy that city officials and King Soopers can clarify before construction begins. The council vote in April 2025 provided the approvals needed to move forward with site plans and permitting.

King Soopers public affairs head Jessica Trowbridge framed the project as a community investment. “King Soopers is excited to continue growing in Douglas County with a new location in the RidgeGate community. This store allows us to expand access to fresh, affordable, and delicious food through a convenient one-stop shopping experience. We look forward to serving our neighbors, creating new jobs, and further strengthening our connection to the community,” she said.

Local reporting also repeated a corporate comment that the project “allows us to grow our footprint, better serve our loyal customers, and invest in the future of this community.” That account associated similar new-store projects with multimillion-dollar investments and sizable hiring, including reports that comparable marketplace openings have created more than 250 jobs and represented a $23.6 million investment in other markets. King Soopers is a Denver-based grocery chain that operates marketplace-format stores that are larger than traditional locations and typically sell non-grocery items alongside full grocery assortments and amenities such as coffee shops, specialty counters, fuel stations and pharmacy drive-thrus.

For RidgeGate residents the immediate impacts will include new retail choices, potential employment opportunities and added traffic around the RidgeGate Parkway interchange and adjacent neighborhoods. Planners will need to address access, parking and traffic mitigation as construction proceeds. The project also raises questions for local oversight: officials and the developer will need to confirm the final construction schedule, the number of permanent and seasonal jobs expected on site, and the exact investment tied to the Lone Tree project.

Next steps for readers include watching Lone Tree City Hall permit filings and developer updates for construction milestones and projected opening dates. Community members concerned about traffic, deliveries or neighborhood impacts should monitor public hearings and planning documents as the RidgeGate King Soopers moves from plan to pavement.
