Council rejects Avalon Bay conditional‑use permit for 435‑unit proposal at former Welby Gardens after marathon hearing

Arvada City Council voted on the conditional‑use permit for Avalon Bay’s proposal to build 384 multi‑family units and 51 town homes (435 total) on the former Welby Gardens nursery, but the motion to approve the CUP failed after an extended hearing and debate.

Todd Nicotra, a Colorado director for Avalon Bay, summarized the application as a 20.1‑acre infill plan intended to deliver a mix of housing types and to fund environmental cleanup under Colorado’s voluntary cleanup program. “Change is coming,” he told the council; “what we are proposing is more compatible with the surrounding area than the vast majority of uses that are actually allowed on the land today.”

Planning staff and planning commission recommended approval, saying the mixed‑use suburban (MXS) zoning allows single‑use residential configurations and that the conceptual plan met the city’s conditional‑use criteria on balance. Planning staff noted the CUP itself is a use determination; detailed designs, including stormwater and remediation plans and the final building plans, will be reviewed at the site‑plan stage if the CUP had been approved.

Opponents — many speaking as pooled HOA or neighborhood groups — urged denial. Their principal arguments included: - Fire and emergency access: Several speakers and the Fire‑Marshall’s commentary said the proposal lacked two independently usable, separated fire‑apparatus access routes required by code for projects of this scale. Neighbors said the proposed secondary/contingent route relied on access through Morningstar senior living property or converged into shared internal circulation, creating a single point of failure in an emergency. - Traffic and cut‑throughs: Neighbors and Jefferson County reviewers questioned the applicant’s traffic‑distribution assumptions and said that added peak‑hour traffic would encourage drivers to use residential streets as cut‑throughs, worsening safety for nearby neighborhoods. - Environmental contamination: Multiple environmental professionals and local residents said the site has legacy pesticide contamination (public speakers cited elevated dieldrin readings) and urged a full CDPHE voluntary cleanup plan and materials‑management plan be completed and approved before any residential approvals.

After rebuttal and extended council questioning — including detailed exchanges about site layout, independent emergency access, the scope and timing of remediation and the city’s authority under the MXS zoning — council took a motion to approve the conditional use on final reading. That motion failed when several council members concluded the application did not adequately demonstrate consistency with some elements of the comprehensive plan and conditional‑use criteria, particularly on access/traffic and evidence of environmental remediation in the record. The planner’s and applicant’s positions that the use is allowed under MXS and that the voluntary cleanup process would be invoked did not persuade the council majority.

What happened at the meeting: The planning commission had recommended approval; more than 100 residents and pooled groups delivered testimony over several hours. Council members who opposed approval said the record lacked evidence that key findings (for example, adequate, prior‑or‑as‑part‑of‑development facilities and mitigation) could be made now. Council members who supported the motion emphasized the site’s mixed‑use zoning, the developer’s commitment to remediation via CDPHE’s program, and the need for attainable housing in West Arvada.

Next steps: The applicant may revise the project, refile a modified application, or pursue site‑plan steps if they choose to address the council’s concerns. Neighbors and referral agencies asked for clearer, documented remediation and traffic‑mitigation commitments in the record before any future decision.
