Backyard ADU plan in riverfront buffer draws technical questions from commission

Thorson Ail, a professional wetland scientist representing Backyard ADUs, described a constrained lot where the applicant proposes a roughly 650-square-foot ADU attached near an existing garage and partly within the 100-foot buffer to riverfront resource areas. "The client has done a lot of work trying to find the best location for it," Thorson told the commission, emphasizing efforts to keep the structure away from mapped wetland flags and to provide mitigation plantings in accordance with riverfront-area regulations.
