Logan Council pauses changes to critical-lands rules after hours of public comment on wetlands, riparian buffers and flood risk

Mike Desimone, a city planning staff member, opened a public hearing on Ordinance 25-11, saying the proposal would amend the city—ritical-lands overlay (Chapter 17.24 of the Land Development Code) to clarify how the city regulates wetlands, floodplains and riparian areas. "We're gonna talk about, ordinance 25 11. It's a proposal to amend the critical lands overlay zone in chapter 17 24 of the land development code," Desimone said, and walked the council through differences between perception and mapped delineations for wetlands and the 100-year floodplain.

The proposed changes would, in many built-up areas, replace the code's three-tier riparian buffer (0-50, 50-100 and 100-150 feet with a 100-foot building setback) with a single 25-foot riparian buffer measured from the ordinary high-water mark. The draft also clarifies that wetland protections apply only to jurisdictional wetlands recognized by the U.S. Army Corps of Engineers, requires wetlands delineations only when a project is within roughly 100 feet of the national wetland inventory mapping, and narrows certain clearing limits and nonconforming-structure rules.

The nut graf: The ordinance is a technical rewrite designed to make riparian and wetland rules easier to administer, particularly for infill lots; opponents warn the changes would reduce protection for mapped and unmapped waterways and increase flood risk, and proponents say the revision corrects impractical setbacks in built neighborhoods and aligns regulation with federal delineations.

Residents, neighborhood leaders and scientists widely addressed the council. Hillary Shukart, a Wilson Neighborhood Council representative, urged using the Logan River Task Force and other local expertise before adopting changes. Suzanne Janicki, an emerita USU geosciences professor, warned the city nalysis had not used modern topographic or LIDAR data and urged larger setbacks due to increasing flood severity. Multiple speakers said the proposed change would reduce buffers from 100 feet to 25 feet and risk future property damage; several asked for more detailed flood mapping and review.

Property owners involved with the Willow Lakes subdivision testified that they had already spent time and money to obtain Corps delineations and that portions of their plat are vested under the rules in effect when their permit and plat were approved. Kent Hogan and Brad Hogan, who described themselves as property owners/developers, said they had followed Army Corps delineation processes and that a 25-foot buffer is reasonable for their site. Mike Desimone explained the distinction between properties that are "platted" or vested and smaller infill lots that are surrounded by existing development.

Council members expressed detailed questions about how the new definition of riparian area would be applied and asked staff for clearer, parcel-level analysis of what land would be affected under the current code versus the proposed text. Several council members said they were concerned about the policy tradeoffs and the number of substantive technical questions raised by the public comments.

Outcome: the council voted unanimously to continue Ordinance 25-11 for further study and refinement; the transcript records a continuance motion and a roll-call vote of ayes from the council, with the item scheduled to return to a future meeting. The meeting record shows conflicting dates offered for the continuance (the body discussed continuing the matter to October 7 but the roll-call referenced October 2); staff said any substantial changes would be referred back to the Planning Commission and that they would provide mapping of vacant/developable land under both the existing and proposed standards.

What remains unresolved: (1) whether the city will formally adopt the proposed 25-foot riparian buffer for infill and the precise geographic areas where the smaller buffer would apply; (2) whether the council will require additional floodplain/LiDAR analysis and explicit treatment of off-site wetlands when adjacent property owners have not delineated them; and (3) whether vested plats (for example, Willow Lakes) retain protections under the prior code. Council directed staff to return with more data and recommended referral back to Planning Commission if the draft is substantially revised.

Ending: The hearing and continuation signaled that the council will not finalize the amendment until staff supplies parcel-level impact analyses and the council can weigh the tradeoffs between infill equity and broader environmental protection.
