Driveways & sidewalks in Snoqualmie: what to know

SMC 12.19.030(A) requires a Type A right-of-way construction permit before work begins in the public right-of-way. Its examples include driveways, curbs, stormwater infrastructure, and sidewalks. We treat every cut at the curb or the walk as a right-of-way matter. On the building side, SMC 15.04B.090(C)(6) exempts driveways accessory to residential buildings built under the International Residential Code when they sit 30 inches or less above adjacent grade and no basement or story lies below them.

Our grade survey for a Snoqualmie drive records the street edge, the drive midpoint, and the garage floor, so the pitch can be checked on paper. Where the soil drains quickly, roof and drive water goes to a separate outlet on the lot rather than onto the street or a neighbor’s yard. Snoqualmie’s stormwater code adopts the 2021 King County Surface Water Design Manual with the city’s addendum, so we confirm the addendum’s current threshold for the lot before the apron is formed.

Permits and rules in Snoqualmie

Ahead of scheduling, we check whether the curb and walk work needs a Type A right-of-way construction permit, and we check the drive against the building exemption in SMC 15.04B.090(C)(6). A separate test under SMC 15.20.030(C) covers clearing and grading, and that section’s grading-volume and new-impervious-area conditions are checked against the drive. The schedule waits for the city’s written answer.

Rules change and vary by parcel, so we confirm the current requirements with the city before we start.

Questions from Snoqualmie homeowners

Do I need a permit at the curb for a Snoqualmie driveway?

Work in the public right-of-way does. SMC 12.19.030(A) requires a Type A right-of-way construction permit before any work there, and driveways and curbs are among its examples. A drive that stays on your lot is a building question, so we check both before the forms go in.

Who repairs a broken sidewalk panel at my Snoqualmie frontage?

A panel in the public right-of-way is a right-of-way question under SMC 12.19.030(A), which names sidewalks among its examples. Who keeps up the frontage walk is a question for city staff, so we confirm it before we quote the repair.

Could I make my Snoqualmie driveway wider?

A wider slab on your lot is judged under the building exemption in SMC 15.04B.090(C)(6), which covers driveways that sit 30 inches or less above adjacent grade. A wider connection to the street is a right-of-way question under SMC 12.19.030(A), so we measure both before drawing the new layout.
