Steilacoom code titles and the state rule
Steilacoom’s code is published by title, and five of them touch concrete and drainage work. SMC 12.20 requires a street work permit before anyone cuts, digs, or disturbs a street, curb, or other improvement, and it names driveway and curb-cut work. A new public sidewalk needs its own extension application under SMC 12.16.010. Chapter 13.70 requires a site development permit for earth moving over 50 cubic yards, and SMC 13.12.020 sets the permit and connection charge for a storm connection. SMC 13.28.020(a) bars stormwater from the sanitary sewer. Chapter 15.04 adopts the 2021 International Building Code and Residential Code, and SMC 15.04.060(a)(1) exempts driveways, decks, sidewalks, and platforms 30 inches or less above grade when no basement or story lies below. The state four-foot rule still governs a retaining wall: a wall not over four feet from the footing to the top is exempt unless it carries a surcharge or impounds a Class I, II, or III-A liquid. Title 18 sets fence and wall limits in street setbacks under SMC 18.20.080.
