The Superior Town Council is scheduled to consider a revised Rock Creek Ranch development plan Sept. 14 that would replace a planned 360-unit apartment project with up to 226 for-sale homes, including 34 permanently deed-restricted affordable ownership units.

The Town Council agenda packet schedules a public hearing on the proposed 25th amendment to the Zaharias property’s planned-development plan, case PDA-2026-02.

The proposal covers a 22.68-acre, long-vacant site east of South 88th Street and north of Hodgson-Harris Reservoir. The developer’s presentation describes 110 detached single-family homes and 116 townhomes, with a maximum density of 10 homes per acre.

The plan also includes a community and playground area, a public trail and wildlife-viewing area, and at least a 100-foot reservoir buffer that would be dedicated to the town. Buildings would be limited to three stories and 45 feet, following a Planning Commission recommendation.

Proposed traffic improvements include a signal at South 88th Street and Promenade Drive, turn lanes at both site entrances and developer-funded transportation improvements. The presentation estimates 131 morning peak-hour trips and 161 afternoon peak-hour trips and lists about $1.3 million in reimbursement to the town for South 88th Street infrastructure improvements.

The developer estimates that producing the 34 affordable homes would leave an approximately $9.7 million financing gap. Its proposed financing package includes about $2.21 million in fee waivers, a $2 million seller contribution or purchase-price reduction, and a request to raise the metropolitan district’s authorized property-tax cap to 50 mills. The presentation estimates that the higher cap could allow about $4.5 million in district reimbursement, compared with $2.25 million under the existing cap.

The mill-cap request is not a final homeowner cost. The developer’s presentation uses an example 80% area-median-income Boulder County household earning $121,472 annually and estimates about $329,000 in principal-and-interest financing after accounting for other monthly housing costs. The estimate assumes a 6.75% interest rate and would not apply to every buyer.

The presentation also projects about $777,830 in annual property-tax revenue from the completed development and enrollment of 41 elementary-school, 24 middle-school and 30 high-school students. It says the Boulder Valley School District can accommodate those projections.

If the council advances the amendment, the project would still require final development-plan review before final maps are executed and recorded.
