Planning commission forwards Longmont Gateway Northwest annexation to city council after heated traffic and safety debate

The Longmont Planning & Zoning Commission on June 17 voted 5–2 to forward the Longmont Gateway Northwest annexation, proposed Residential Mixed Neighborhood (RMN) zoning and a concept plan to the Longmont City Council for final consideration.

Senior planner Kristen Cody told the commission the annexation would bring approximately 266 acres into the city and apply RMN zoning that anticipates a range of housing types and densities — roughly 6 to 18 dwelling units per acre — with lower‑intensity homes bordering existing neighborhoods and greater intensity near U.S. 287. Cody said the annexation and concept plan are high‑level approvals only and that detailed entitlements (subdivision, site plans, utilities and roadway designs) will return for later review.

The applicant, Actis, represented by Chris Neils and planner Candace Bernett of Kimley Horn, described a multi‑phase project that the team said responds to council guidance for additional density and seeks to provide ‘‘missing‑middle’’ housing and a transit connection. Neils said the team reworked circulation and transit plans after prior public feedback, adding a proposed signal and reserving four acres for RTD’s bus rapid transit terminus.

Neighbors who live in the adjacent Willis Heights area and other nearby subdivisions voiced strong opposition during a public hearing. Twelve residents spoke, repeatedly raising concerns about increased traffic volumes and cut‑throughs, pedestrian and emergency access, water and sewer availability, wildlife impacts, and potential changes to neighborhood character. Susan Felix said county law enforcement had expressed concern that the development could bring increased transient activity to the neighborhood; she added, “If they put this building in on this property, it's just going to cause more crime and more people sleeping in the neighborhood.” Several speakers challenged applicant traffic counts and asked for updated, multi‑day counts rather than short or holiday counts.

Commissioners focused questions on three technical issues raised by neighbors and county reviewers: access points, fire‑safety access requirements, and environmental/historic protections. Assistant Fire Marshal Mark Samson told the commission that under the adopted International Fire Code and local amendments, projects proposing more than 25 dwelling units require two independent public access points separated by a minimum distance computed from the lot diagonal; he said the two right‑in/right‑out accesses proposed on U.S. 287 are too close together to meet that separation, which is why a Rosland Avenue connection was included on the concept plan. Samson characterized that requirement as a public‑safety necessity rather than a convenience for cut‑through trips.

Historic preservation staff said the site contains an intact historic farmstead. Jennifer Huitt Apperson, staff liaison to the Historic Preservation Commission, said the HPC recommended that the annexation agreement include a preservation plan that gives “particular consideration” to preserving the primary farmhouse, possibly by relocating it on site, rather than allowing its demolition.

On wildlife and environmental issues, staff confirmed a species and habitat report was submitted at the conceptual stage noting prairie dogs and nesting‑bird protections; Cody said detailed mitigation and mapping (for raptor nests, wetlands, drainage design, and prairie‑dog management) will be required and reviewed at the subdivision and site‑plan stages.

Traffic consultant Kimley Horn told commissioners that the proposed signal at the north project entrance is warranted, that CDOT is coordinating corridor safety improvements, and that the mitigation recommendations in the traffic study (turn lane storage, signage and signalization) would remain applicable as the design advances. The consultant said that if Rosland is required to be a full public access the network would still operate acceptably from an engineering perspective, but that engineers generally prefer emergency‑only access to avoid placing neighborhood traffic on local streets.

Several commissioners said they were persuaded by the staff and applicant case that the parcel could be developed in a way consistent with Envision Longmont goals and that necessary technical issues could be managed through conditions and later reviews. Vice Chair Earl and Commissioner Lang dissented in the final vote, expressing discomfort with a potential public access through the Willis Heights neighborhood and with outstanding traffic details. The clerk recorded a 5–2 vote forwarding the annexation, RMN zoning and concept plan to city council (Yes: Commissioners Edgely Wells, Poland, Arment, Boon, Jordan. No: Lang, Vice Chair Earl).

What happens next: the annexation and concept plan will be scheduled for a city‑council public hearing and decision. Staff and the applicant will need to resolve specifics on access (public vs. emergency Rosland connection), finalize drainage and water‑rights strategies, submit detailed wildlife and historic‑preservation mitigation proposals, and supply further traffic modeling if Rosland is designated for public access.
