Concrete Overlays in DuPont, WA

Concrete overlays in DuPont: what to know

The city’s maintenance chapter places sidewalk and driveway upkeep on the owner. Once notified, the owner gets 60 days to secure a public works permit and complete the repair before the city steps in, so frontage repair is scoped as owner work with a permit. The right-of-way chapter also requires a permit before work on sidewalks or driveway openings begins, so the frontage piece waits for that permit.

A private overlay is checked against the 2019 Ecology manual that the city adopts. The city text we reviewed does not state the manual’s thresholds, so whether a resurfacing coat counts as new or replaced impervious surface is confirmed with the city before the coat is ordered. No DuPont overlay rule has been located, so the coat is scoped on the city’s written answer.

Permits and rules in DuPont

We confirm which frontage pieces are repairs the city can order and which are owner maintenance, and we confirm the impervious question for the slab in writing. Any frontage piece waits for its right-of-way permit, and the coat is not ordered until both answers are on file. The scope records each reply with its date.

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

How we approach it

Split the frontage sidewalk from the private slab
Confirm whether a coat adds impervious surface
Hold the frontage piece for its right-of-way permit
Record each city reply with its date on the scope

Questions from DuPont homeowners

Does a DuPont overlay need a permit?

Frontage work in the rights-of-way needs a permit before it starts. A private slab overlay goes to the stormwater question, and the city’s written answer on impervious area sets the scope.

Who keeps a DuPont sidewalk in repair before an overlay?

Upkeep of the frontage sits with the owner under the city’s maintenance chapter, so a repair becomes part of the owner’s scope. If the city gives notice, the owner gets 60 days to secure the permit and finish the work.

Does a new coat count as replaced surface in DuPont?

The city text we reviewed does not say. The city adopts the 2019 manual, so the impervious question goes to the city in writing before any material is ordered.
