Snoqualmie committee advances critical‑areas ordinance with 250‑sq‑ft single‑family exemption

Snoqualmie

The Snoqualmie Community Development Committee voted to forward proposed updates to the city—s critical‑areas ordinance to the full City Council, endorsing larger riparian protection zones while preserving a 250‑square‑foot exemption for previously permitted single‑family yards.

The committee—s move follows a presentation by Jeff Gray, a senior scientist with OTEC, who said state guidance from the Washington Department of Fish and Wildlife (DFW) frames the change from the traditional term "stream buffers" to "riparian management zones." Gray told the committee that these areas "provide five main ecological functions: stream morphology, fish habitat, large wood, stream temperature, pollutant removal and nutrient dynamics." He said the proposed draft code tracks DFW—s recommended buffer distances, subject to local constraints.

Why it matters: The proposed changes increase buffer widths around streams in Snoqualmie (in many places where implementation is possible) and could affect future development, permitting and property improvements. Committee members stressed that much of the city is already encumbered by mapped wetlands, stream channels and floodplain, which limits where wider buffers can be applied without further field verification.

What the ordinance would change: The draft ordinance (as presented) would rename stream buffers to riparian management zones and would, in broad strokes, increase buffer distances to align with DFW recommendations: Type F (fish‑habitat) streams would move from roughly 75 feet to about 200 feet; smaller non‑fish streams would move to a DFW minimum of about 100 feet. The draft also adds two implementation provisions: an exemption for "functionally isolated" riparian zones (areas separated from the watercourse by a road, structure or other barrier) and a limited allowance for single‑family properties.

Single‑family exemption and Planning Commission proposal: The Planning Commission had recommended increasing the single‑family allowed improvement area from 250 to 500 square feet; during committee discussion several council members, including Council Member Johnson, favored retaining the 250‑square‑foot exemption as a negotiated compromise reached with Fish and Wildlife and consultant input. Director Davis said staff would amend the agenda bill to reflect the 250‑square‑foot allowance and move the ordinance to Council for first reading.

Flood hazard and timing: Gray reviewed flood‑hazard considerations and said staff is not proposing immediate changes to finished‑floor freeboard in the city code because King County—s hydraulic modeling (which showed a modeled 1.4‑foot reduction in the 100‑year base flood elevation in parts of the city following county projects) has not been incorporated into FEMA official maps. Gray said FEMA map updates and a potential letter of map revision are expected as part of a 2026–2027 schedule; staff said they will revisit local freeboard requirements after those official map changes. Director Davis and Council Member Johnson noted the ordinance requires two council readings and that RCW timing could affect adoption schedules toward the end of the year.

City projects: Gray said downtown projects within shoreline jurisdiction (including the model train museum and certain gateway parcels) would not be affected by the changes because shoreline regulations already govern Type S streams such as the Snoqualmie River. The Snoqualmie Valley Hospital and the dog park are vested or under construction and would not be changed by the draft. Mill site phase 2 and 3 could face minor impacts depending on later DFW stream typing and project plans.

Committee action and next steps: The committee directed staff to amend the agenda bill to reflect a 250‑square‑foot single‑family exemption and to forward the ordinance to City Council for its initial reading at the next council meeting, with a second reading to follow as required by city code. No formal roll‑call vote on the ordinance was recorded at the committee level; Chair Louis Washington closed the item by noting there were no objections to moving forward: "There are no objections. We'll move forward."
