Council workshop reviews proposed critical‑lands code changes, including smaller riparian and wetland setbacks

City planning staff led a workshop on proposed amendments to the city’s Critical Lands Overlay (Chapter 7.2.24), focusing on riparian setbacks, wetland buffers and procedures for review and mitigation. The council did not vote; a public hearing was scheduled for the next regular meeting.

Community Development staff said the proposed changes aim to simplify regulations in an already largely developed city and to resolve conflicts encountered in recent projects. Key proposals include narrowing certain riparian and wetland setbacks (staff proposed a 25‑foot standard in many cases rather than the current tiered 50–100–150 foot approach), clarifying that city rules apply only to jurisdictional wetlands as defined by the U.S. Army Corps of Engineers, and allowing parks, trails, utilities and stormwater facilities within buffers when designed and approved by the city. Staff noted overlapping jurisdictions (floodplain, Corps jurisdictional wetlands, state stream alter permits) and sought to reduce duplicative reviews.

Using Willow Lakes and Hogan Estates as case studies, staff showed mapping of potential wetlands, FEMA‑recognized floodplains and proposed lot layouts under the revised standards. Staff said Willow Lakes will include a conservation easement along the river and mitigation work in a man‑made channel that the state now considers jurisdictional; those mitigation steps include creating wetlands and improving riparian habitat. Staff acknowledged the proposed changes would affect buildable unit counts: for one project the proposed setback reductions allowed about 25 units versus about 10 units under the previous rules.

Councilmembers asked about past flood events and how modern floodplain protections differ from older development; staff said current standards require finished floors at least one foot above base flood elevation and that any fill in floodplains must be accounted for on site. Staff also told the council the Planning Commission recommended approval at its hearing and that the council will hold a formal public hearing at the next meeting (August 19).

Staff framed the proposal as a balance: protect important resources while allowing the city to construct roads and infrastructure without excessive acquisition costs or unworkable setbacks on mostly built‑out land. Councilmembers requested additional review, said they would file written comments, and acknowledged that the revisions grew out of recent project experience.
