Thornton City Council has approved annexation and zoning for Creekside Gardens, a proposed 416-unit mixed-use development at the southwest corner of East 104th Avenue and Washington Street. Evergreen Devco's plan includes 250 market-rate apartments, a 166-unit senior-living community and commercial space, according to The Real Deal.
The decision arrives as Thornton faces a substantial long-term housing requirement. The city's 2024-2029 Housing Needs Assessment projects 50,000 to 65,000 additional residents by 2040 and says the city will need 20,000 to 25,000 new homes to accommodate that growth. Thornton separately estimates that 11,500 to 12,000 additional housing units will be needed by 2032, according to the city's housing webpage.
Senior housing is a documented need, but affordability is unsettled
The senior component responds to a demographic trend identified in city planning documents. Thornton's Housing Needs Assessment says the city's senior population grew to 14,270 in 2022 and is projected to reach 25,115 by 2032. The city's draft 2026 Annual Action Plan also identifies a shortage of affordable senior housing, from assisted living through full care.
Those figures establish a local need for additional housing for older residents, not the affordability or eligibility of Creekside Gardens' planned units. The same draft action plan says 59% of Thornton renters are cost burdened and lists limited accessible and affordable housing as city obstacles. No rents, income restrictions or subsidy arrangements for the project have been announced.
Approval follows years of water-supply conflict
Thornton's approval process has unfolded against the backdrop of the city's long-running effort to build a pipeline from water rights in the Cache la Poudre River basin. The city began acquiring those rights in the 1980s and received water-court approval in 1996, while permitting disputes and legal challenges delayed the project for decades, according to Lyons Gaddis.
A major legal obstacle was removed in 2025 when Save the Poudre dropped its challenge after a Larimer County judge upheld the county's construction permit, The Colorado Sun reported. The Real Deal describes Creekside Gardens as one of the first major projects to advance after Thornton resumed selling new water taps, but the available reporting does not establish the project's specific tap allocation, water-service conditions or whether its approval depends on any particular pipeline milestone.
Water remains an active constraint rather than a settled issue. Thornton's water department says the city manages a diverse portfolio that includes senior rights dating to the 1860s, while its current water page lists Stage 1 drought restrictions. Those citywide facts provide context for the approval but do not confirm project-specific supply or conservation requirements.
What the approval does—and does not—establish
Creekside Gardens would occupy 26 acres, with the apartment and senior-living portions accounting for most of the announced residential program. The project is being led by Evergreen Devco, with Ryan Companies associated with the senior-living component, according to The Real Deal.
Council approval permits the development to proceed through subsequent design, engineering and construction stages; it does not guarantee that all components will be built at once or establish a firm opening date. The project's total cost, final rents, affordability requirements, construction schedule and any future expansion of commercial space remain undisclosed in the available records.
