Driveways & sidewalks in Silverdale: what to know

The approach follows Section 4.3, Road Approaches, of the county road standards adopted June 8, 2020 as Ordinance 588 (2020). Section 4.3.3, Construction Criteria, requires every approach to be paved to the right-of-way line or 3 feet beyond the end of the radius, whichever is greater, and it sets the minimum thickness at 3 inches of compacted hot-mix asphalt (HMA) over 2 inches of crushed surfacing top course, or 6 inches of reinforced concrete. The road approach brochure points to Figures 4-3 through 4-5 for design examples. We have not read those figures, so the width and grade limits are confirmed with county staff before forming.

The slab on private ground is judged apart from the approach. The building brochure says a driveway or sidewalk needs a permit when it rises more than 30 inches over grade or spans a basement or lower story, and the line drops to 18 inches on shoreline parcels. The road approach brochure says an approach built with a new home needs no separate permit, so we check the job type first.

Permits and rules in Silverdale

Before quoting, we check the slab height against the 30-inch line and the shoreline status of the parcel, and we confirm the road approach permit with Kitsap County DCD. The approach is scoped with its paving thickness and its right-of-way line. Any county reply still outstanding stays marked open on the scope until it is in writing.

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

Questions from Silverdale homeowners

Is a county road approach permit needed where a Silverdale drive reaches a county road?

Yes, when the driveway connects private property to a county road, according to Kitsap County’s road approach brochure. The same brochure says that building the approach with a new home needs no separate permit, so we confirm the job type before the scope is set.

How thick does the paving under a Silverdale approach need to be?

Section 4.3.3 of the county road standards requires at least 3 inches of compacted hot-mix asphalt (HMA) over at least 2 inches of crushed surfacing top course, or 6 inches of reinforced concrete. Gravel county roads may instead use a 4-inch layer of that same material. We confirm which option applies to the road before the forms go in.

When does a Silverdale walk or drive slab need a building permit?

The building brochure says a driveway or sidewalk needs a permit when it rises more than 30 inches over grade or spans any basement or lower story. On shoreline parcels the line drops to 18 inches. We measure the height above grade, check for any story below, and confirm the answer with county staff before scheduling.
