Concrete Driveways & Sidewalks in Fall City, WA

Driveways & sidewalks in Fall City: what to know

A driveway that links an adjacent parcel directly to a maintained county road needs no right-of-way permit, but it must still follow the county’s road standards. Other private work inside the county road right-of-way does need a permit, and a limited permit lapses one year after it is issued. Sidewalks and driveways that rise 30 inches or less from grade, with no basement or story underneath, fit the exemption list in King County Code 16.02.240.

The drainage side counts the whole hard surface. Driveways, patios, and parking areas are named as non-structure impervious surfaces, so they count toward the total, and once new and replaced hard surface reaches 2,000 square feet, the residential drainage review applies. Cumulative earth moving above 100 cubic yards is tracked on the same lot, so a regraded apron is totaled with the rest of the job.

Permits and rules in Fall City

Before a pour date, we check the apron against the county road frontage, confirm whether the connection is direct or needs county right-of-way approval, and total the lot’s hard surface against the 2,000 square foot line. Where the work touches a county road, we ask King County in writing and hold the apron until that reply is filed. A limited permit lapses one year after issue, so we schedule the apron inside that window.

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

Questions from Fall City homeowners

Does a Fall City driveway that meets a county road need a right-of-way permit?

A driveway linking an adjacent parcel straight to a maintained county road needs no right-of-way permit, though the link must follow the county’s road standards. Other private work in the county road right-of-way does need one, and a limited permit lapses one year after issue, so we check the connection with King County before pouring the apron.

Does replacing a Fall City driveway trigger county drainage review?

It can. The residential drainage guidance counts 2,000 square feet of new and replaced impervious surface, and driveways are named among the non-structure impervious surfaces. We add the drive to the walk and patio, then confirm whether the lot reaches the line before the layout is final.

When does a Fall City driveway’s height change the county answer?

King County Code 16.02.240 exempts sidewalks and driveways that rise 30 inches or less from grade and have no basement or story beneath them. A taller drive, or one over a space below, falls outside that exemption, so we measure the finished height and ask King County before forming it.
