Concrete Driveways & Sidewalks in SeaTac, WA

Driveways & sidewalks in SeaTac: what to know

The city’s right-of-way page gives driveway access points and pedestrian walkways as examples of right-of-way projects, along with stormwater drainage systems, utility lines, and pavement work. A driveway that touches a storm drain or ditch can therefore carry more than one permit question at once.

On the lot, the clearing and grading code exempts maintenance of existing driveways within their existing road prisms. A new drive is measured differently. 2,000 square feet of new or replaced impervious surface is a trigger on the city’s STE page, and so is 50 cubic yards of cut or fill. We total the new and replaced surface before the layout and confirm which trigger, if any, applies.

Permits and rules in SeaTac

We confirm with the city whether the apron, curb, or walk falls in the City right-of-way, and whether the new and replaced surface on the lot reaches a clearing and grading trigger. We also confirm the business license requirement for work in SeaTac, since the city code says no person may engage in business in the city without first being issued one.

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

How we approach it

Settle the permit path for the apron, curb, and walk before the forms go in
Total the new and replaced impervious surface against the 2,000 square foot trigger
Measure any cut or fill against the 50 cubic yard trigger before the grade is changed
Hold sidewalk and curb work until the city’s permit path is set

Questions from SeaTac homeowners

Does a new driveway in SeaTac need a right-of-way permit?

Work inside the City right-of-way is covered by the city’s right-of-way permit, and driveway access points appear among its examples. We confirm whether the apron, curb, or walk on your lot falls inside the right-of-way before the forms go in.

How much new paving in SeaTac triggers a clearing and grading permit?

The city’s STE page lists 2,000 square feet of new or replaced impervious surface as a trigger, along with 7,000 square feet or more of land-disturbing activity and 50 cubic yards or more of cut or fill. We total the drive and walk against those numbers before the layout.

Does concrete work in SeaTac need a city business license?

The city code says no person may engage in business in SeaTac without first being issued a business license, and it lists installing or constructing real or tangible personal property among the covered activities. We confirm the license requirement for each SeaTac job before we bid it.
