Yelm council approves interlocal agreement with Thurston County to begin annexation planning

YELM — The Yelm City Council on Dec. 9 approved an interlocal agreement with Thurston County that lays out how the two jurisdictions would divide responsibilities if the city moves forward with an annexation.

"Approval of the interlocal agreement does not approve the annexation. It's just a prerequisite," planning and building manager Gary Cooper told council members as he introduced the draft agreement and the next steps. The council voted to approve the agreement after a brief public hearing that drew no testimony.

Cooper said the agreement is intended to "pass the baton" between county and city staff, covering property records, permits in progress, stormwater maintenance records and other administrative matters that must be resolved before a formal annexation ordinance can be considered. He estimated affected property owners would see a small increase in property taxes if annexed — "about $10 per month," he said — and said existing private wells could remain in use until they fail.

During the discussion, staff clarified that properties within 200 feet of city water or sewer mains would be required to connect; other details would be communicated to residents as the process proceeds. Cooper said the city would mail a six-page letter and frequently asked questions to property owners in the study area the next day and host an open house on Dec. 23 at the community center.

Councilor Blittman moved to adopt the interlocal agreement; the motion was seconded and passed by voice vote. Cooper said staff would return to council with a proposed annexation ordinance on Jan. 16 if the city moves forward.

What happens next: affected property owners will receive a mailed notice and FAQ, the city will hold a Dec. 23 open house at the community center, and staff expect to return with a proposed ordinance for council consideration on Jan. 16.
