Full report
Clackamas County commissioners have unanimously approved two boundary changes bringing Happy Valley redevelopment sites into Clackamas County Service District No. 1 (CCSD1), clearing the way for the properties to seek sewer service.
The more substantial of the two actions, Boundary Change Proposal 2026-009, covers a property at 14548 SE 172nd Avenue. County staff said the petitioner plans to redevelop the site as a mixed-use project with multifamily and commercial uses. Submitted information identified 199 multifamily units.
The board approved the annexation 4-0 after receiving no public testimony. Staff said the application complied with applicable codes and ordinances, notices had been issued, and no objections had been received.
Commissioners also approved, by the same 4-0 vote, Boundary Change Proposal 2026-004 for 11801 SE Mount Scott Boulevard. The property, already annexed to the City of Happy Valley, is seeking a CCSD1 sewer connection to support future redevelopment.
Unlike the second case, the Mount Scott Boulevard hearing drew a comment from a nearby resident, who said the property backs on to his home and asked what the planned sewer work and redevelopment could mean for his backyard, view and trees. The resident said he was not opposed to the proposal but wanted further information.
Assistant County Counsel Jeff Muns said county staff could discuss the sewer annexation with the resident, while development approvals would proceed through the City of Happy Valley's land-use process, where there would be further opportunities for input.
Staff said the Mount Scott Boulevard annexation had received Department of Revenue approval and complied with Happy Valley code, the county comprehensive plan, relevant annexation ordinances, state statutes and Metro Code. Neither boundary change involves county general funds.
