Pulling a Clearing and Grading Permit? Here's What the King County Clearing and Grading Bond Covers
If King County told you that you need a financial guarantee before your clearing and grading permit is issued, you are in the right place. That guarantee is often called a King County clearing and grading bond, and it is a normal part of moving dirt, cutting into a slope, or reshaping a site in unincorporated King County. It is usually straightforward once you know what the county is asking for.
We have been writing surety bonds since 1971, and we place these guarantees across Washington every week. If you already know your permit number and the amount the county set, we can move quickly. Give us a call at 800-333-7800 and we will walk you through it.
What a King County Clearing and Grading Bond Actually Is
A surety bond is a three-party promise. You are the principal, the one doing the work. King County is the obligee, the party requiring the bond. The surety is the company that stands behind you. If you finish the clearing, grading, drainage, and restoration work the way your approved permit says, nobody ever touches the bond and it quietly expires.
If the work is left unfinished or does not meet the permit conditions, the county can make a claim against the guarantee to cover the cost of correcting it. Here is the part people miss: a surety bond is not insurance for you. If the surety pays a claim, you are expected to pay the surety back. That is why the county accepts it.
It is one of many Washington surety bonds tied to local permits, and among the more common ones we see out of King County.
Who Needs One, and When It Comes Up
King County generally requires a clearing and grading permit when the work crosses certain thresholds. That includes moving more than 100 cubic yards of material, filling three or more feet deep, excavating five or more feet deep, adding new impervious surface, or clearing land inside the Urban Growth Boundary. Work in or near critical areas, such as wetlands, steep slopes, or landslide hazard areas, can trigger it too.
When your permit involves restoration, drainage, or site reclamation the county wants to see finished, the Permitting Division will condition the permit on a financial guarantee. That is the moment the bond comes into play, and you typically cannot get final approval until the guarantee is in place.
A note on geography. This page is about unincorporated King County, where the Department of Local Services is the permitting authority. A project inside the City of Seattle answers to a different agency, so you would look at a Seattle grading bond instead, and a job in Bellevue would call for a Bellevue clearing and grading bond. Same idea, different obligee. If you are not sure which applies, we can help you sort it out.
How the Bond Amount Gets Set
There is no flat amount for these guarantees. King County sets the number based on the estimated cost to complete and restore the improvements tied to your permit, meaning the clearing, grading, drainage, and restoration work. The county calculates that figure using current construction, landscaping, and environmental cost data adjusted for the region, and the director may add a contingency.
What that means for you is simple. A small grading job carries a small guarantee, while a large project that reshapes a slope and rebuilds a drainage system carries a much larger one. Because the amount is variable, the smart move is to have your permit paperwork in hand when you call us. If you do not have the number yet, we can still get you started.
Your annual premium is only a small percentage of that bond amount, not the full amount. Most applicants with reasonable credit are pleasantly surprised at how affordable it is.
The Technical Side: Code, the Permitting Division, and What the Guarantee Secures
Clearing and grading in unincorporated King County is governed by King County Code Chapter 16.82, with critical area protections layered in through Title 21A. The Department of Local Services, Permitting Division administers these permits, reviews your plans, inspects the work, and manages the guarantee.
The county's financial guarantee rules sit in Title 27A of the King County Code. King County recognizes more than one form of guarantee, including cash deposits, an assignment of funds through an insured bank or credit union, and surety bonds. Because the accepted form can depend on the phase of work, it is worth confirming with the Permitting Division, or with us, what your permit calls for before you commit.
So what does the guarantee actually secure? In plain terms, it protects the finished condition of your site: drainage that conforms to the approved plans, erosion and sediment control, water quality protection, removal of any geologic hazard the work created, and the restoration the permit requires. King County does not publish a single standalone bond form you download and sign for this. The guarantee is issued through the permit itself, tied to your specific conditions and amount, which is why the number is customized to your project. You can read more on the county's financial guarantees sheet. Once the work is inspected, the Permitting Division releases the guarantee, reducing it proportionately on phased projects as sections are approved.
Frequently Asked Questions
How much does a King County clearing and grading bond cost?
You pay an annual premium that is only a small percentage of the total bond amount the county requires, not the full amount. The exact premium depends on the bond size and your credit. The best way to get a real number is to call us with your permit details.
Why does King County require this guarantee at all?
The county wants assurance that the site will be finished safely, with drainage, erosion control, and restoration done to plan. The guarantee gives King County funds to correct or complete the work if it is abandoned, so an unfinished grading job does not become a drainage or slope hazard.
Is this the same as a Seattle grading bond?
No. This bond is for unincorporated King County, where the Department of Local Services is the permitting authority. A project inside the City of Seattle answers to a different agency with its own guarantee, so match the bond to the jurisdiction that issued your permit.
How long does it take to get the bond?
Often the same day. If you have your permit number and the amount the county set, we can usually get your bond issued quickly so it does not hold up your permit. Larger amounts may take a little more review.
What happens if a claim is made against the bond?
If King County makes a valid claim because the work was not completed or did not meet the permit, the surety may pay the county up to the bond amount, and you are then responsible for reimbursing the surety. Finishing your permitted work as approved is what keeps the bond claim-free. Once the county inspects and approves the work, the Permitting Division releases the guarantee.
