DuPont right-of-way, stormwater, and wall lines
DuPont’s right-of-way chapter requires a permit before work in the public rights-of-way, and its definition of work names sidewalks and driveway openings. Owners and occupants keep the frontage in good repair. After notice, the owner has 60 days to obtain a public works permit and finish a required repair before the city acts.
The stormwater chapter adopts the 2019 Ecology manual for Western Washington and its later editions. The city’s 2024 stormwater management plan lists footing drains, foundation drains, and uncontaminated crawl space pump water among allowable discharges. Numeric triggers are not stated in the city text we reviewed, so drains and added paving are put to the city.
Under the state residential list, a retaining wall no taller than four feet is exempt unless a surcharge presses on it. Exempt decks must also stay within 200 square feet and 30 inches above grade. The city’s 2011 rock-wall standard adds an engineer rule for rock walls above four feet. Grading, approach permits, and the code edition stay open until the city answers.
Nearby, we also build in Steilacoom, Lakewood, Lacey, and Yelm, and we serve the rest of western Washington.
