Longmont City Council approved the first reading of Ordinance 2026-62, covering the proposed Dry Creek annexation and concept plan, by a 7–0 vote on Sept. 22. The council added measures to deter neighborhood cut-through traffic and separately voted 6–1 to require historic-preservation review of an existing silo before preliminary-plat approval, according to the Sept. 22 minutes included in the Oct. 6 council packet.
The traffic condition directs future development, to the maximum extent feasible and with City Engineer approval, to deter northbound through-traffic on Boxelder Drive. It calls for physical controls and signs to deter right turns from the development onto Quail Road, and signs discouraging through-traffic on Boxelder. The traffic amendment passed 7–0.
The silo condition requires referral to the Historic Preservation Commission before preliminary-plat approval. The commission is to review and comment on the silo’s potential historic or cultural significance and opportunities for preservation or adaptive reuse. The referral does not require the silo to be preserved; a separate proposed motion to require preservation was withdrawn.
The amended plan also retains traffic-study and bike-share conditions. The bike-share condition requires any option to be publicly accessible and compatible with the city’s system; it passed 6–1. The traffic study recommends a westbound right-turn lane at the project entrance on Clover Basin Drive and signal-timing changes at Airport Road and Clover Basin Drive. The proposal calls for updating the study with each final plat and building or funding applicable transportation improvements.
The proposed annexation covers about 7.95 acres along Clover Basin Drive and Airport Road in unincorporated Boulder County. Requested Residential Mixed Neighborhood zoning would allow detached, attached and multifamily housing, with maximum densities of 7 to 15 units per acre depending on the housing mix. The applicant anticipates providing 12% of the housing on site as affordable housing; the number and mix of homes have not been set.
