Committee advances LMO text amendment to require multimodal transportation analyses, lowers trip threshold

Chair Becker opened discussion of a proposed text amendment to the town's Land Management Ordinance that would change "traffic impact analysis" to a multimodal "transportation impact analysis," broaden mitigation tools, and lower the development threshold that triggers the plan.

Missy Lueck, the town's director of planning, told the committee the planning commission held a public hearing on April 16 and unanimously recommended the amendment. "We're proposing to reduce the threshold from 100 peak-hour trips to 50, include multimodal infrastructure such as bike paths and sidewalks in the analysis, expand the list of mitigation options and shift subject-matter approval to the town engineer," Lueck said.

Lueck cited recent projects that would have been affected under the new standard, including a 147-unit project on Jonesville Road and a 132-unit office-way project, and said the update is part of the town's growth-management strategy. She also described new standards for unsignalized intersections and elimination of the prior practice of discounting background trips generated by existing development.

Committee members asked whether lowering the threshold would make redevelopment of blighted areas harder or more costly. One committee member raised concerns that stricter mitigation requirements could make projects financially infeasible in areas the town wants to revitalize; the member urged staff to consider exemptions or targeted language for workforce or redevelopment areas. Lueck said affordable-housing thresholds would not change under the amendment and that the town can consider location-based exemptions if the council directs staff to pursue them.

During public comment, attorney Chester Williams warned of legal constraints on mitigation requirements. "You can require a developer to mitigate the adverse impacts that his or her development is going to cause, but you cannot require a developer to mitigate pre-existing problems," Williams said, arguing that denying credit for previously existing trips could raise federal constitutional issues.

Committee members and staff debated process and discretion. A staff member explained that planning-commission review provides back-and-forth about mitigation findings, but that some subjectivity remains and the proposed amendment seeks to limit it where possible. Multiple members asked staff to prepare additional analysis, including sample studies showing how older projects would have been different under the new rules.

After deliberation the committee voted to forward the proposed text amendment to the full town council with a recommendation for approval with conditions, asking staff to incorporate the committee's concerns and produce clarifying language on applicability, downstream impacts and exemptions for redevelopment or workforce housing.

The amendment will next go to full council, where the policy questions raised in committee (how to treat blighted/redevelopment areas, the town's tolerance for level-of-service declines and the legal limits on exactions) are expected to receive further attention.
