Medical Lake panel recommends rewrite of subdivision code, urges higher maintenance guarantee pending state law check

The Medical Lake Planning Commission voted June 25 to recommend that city council adopt a rewrite of the city's subdivision code that formalizes lot-line adjustments and streamlines review procedures while asking staff to verify whether the code's current 110% maintenance guarantee can legally be increased.

Lisa, the city planner, told commissioners the packet included nine substantive changes, including a new chapter to allow lot-line adjustments that ensure minimum lot-size, setbacks and utility easements remain compliant. "A lot line adjustment is when you have two or more properties and you're moving the line in between them, and essentially what we're looking for when you do that is that the lot that's being created still meets our minimum lot size standards," she said, explaining staff's aim to formalize a process that city staff have been administering informally for years.

The rewrite also clarifies review timelines and application completeness requirements. Staff said the municipal code now cites state review timelines and sets clearer criteria for preliminary plats, short plats, surveys and infrastructure requirements so applicants and reviewers can determine completeness within the state-mandated 28-day window.

Commissioners spent the most time on the maintenance-guarantee (performance-bond) level in the proposed code. Commissioner Bob raised concern that the current code's 110% guarantee may be outpaced by construction-cost increases. "As I understand, 110% is what's in the current code," he said, noting lender practices and rising costs. Several commissioners responded that 150% is commonly used and provides greater assurance the city could complete unfinished work without costly legal action.

Staff did not commit to unilaterally raising the percentage but agreed to research state law limits and advise whether the city can require a higher guarantee. The commission voted to forward the subdivision-code amendments to city council with the modification that staff check RCW and other constraints on the 110% figure; if legally permissible, staff will recommend increasing the guarantee before council adoption.

The recommendation to council includes reorganizing streets and utilities standards into distinct code titles and aligning citations to critical-area and shoreline provisions. Staff noted the changes are intended to improve clarity and administrative consistency rather than to alter substantive policy beyond the lot-line-adjustment permission.

Next steps: the commission's recommendation will be transmitted to city council for consideration; staff will report back on any applicable state-law constraints regarding the maintenance-guarantee percentage prior to council action.
