Do You Need a Permit to Clear or Grade Land in Jefferson County?
Most small residential clearing and grading jobs in Jefferson County, WA do not need a county permit. Mowing brush, pulling a few stumps, touching up a gravel driveway or leveling a pad on flat, dry ground is usually fine. The answer changes fast when the work touches a critical area. Wetlands, streams, steep or slide-prone slopes and shoreline lots fall under the Critical Areas Ordinance, JCC 18.22, and need county review before a machine shows up. Cuts, fills or cleared areas over the county's thresholds [VERIFY current thresholds] need a grading permit. Any project that disturbs an acre or more also needs a Washington Department of Ecology construction stormwater permit. Inside Port Townsend city limits, the City of Port Townsend Development Services office has its own rules. Eaglemount Excavation, LLC in Chimacum walks lots across the county and can tell you which of these applies before you spend money on a plan.

Eaglemount Excavation, LLC clears lots and grades building pads all over Jefferson County from our base in Chimacum, and the first question on almost every call is the same: do I need a permit for this? The honest answer is that it depends on where your lot is and what the ground is doing. Most small jobs on flat, dry ground do not need a county permit. Add a wetland, a creek, a steep bank, a shoreline or an acre of bare dirt and the answer flips. This guide walks through the triggers so you can sort out which side you are on before anyone starts a machine.
Which jobs need a permit and which do not?
You probably do not need a county permit when:
- You are mowing or brush-hogging blackberries, scotch broom and small alder on dry, flat ground.
- You are touching up an existing gravel driveway in the same footprint.
- You are moving a small amount of soil that does not change where water runs and will not hold up a building. [VERIFY current county cut and fill thresholds]
- The lot has no wetland, stream, steep slope or shoreline on it or next to it.
You very likely need a permit, or at least a county review, when:
- Any part of the work is inside a critical area or its buffer under JCC 18.22.
- You are cutting or filling more than the county’s grading thresholds. [VERIFY current thresholds]
- The project will disturb one acre or more, counting future phases.
- You are building a house, shop, driveway or wall that needs a building permit anyway. The grading rides along with it.
- The lot is inside Port Townsend city limits.
- You are harvesting timber to sell, or converting forest land to a home site.
If you are not sure, the cheapest step is a phone call to the permit office before the excavator shows up.
What is the Critical Areas Ordinance and how does it affect clearing?
Jefferson County’s Critical Areas Ordinance is Chapter 18.22 of the county code. It protects land the county has decided is fragile, or dangerous to build on. If your project touches one of these areas, or the buffer around it, you need county review even for work that would otherwise be exempt. The Jefferson County Department of Community Development (DCD) runs that review for everything outside Port Townsend city limits.
Wetlands
Wetlands on the Peninsula are not always obvious. Many are wooded and dry out by August. Skunk cabbage, sedges, standing water in February and soft, dark soil are all signs. The county rates wetlands by category and sets a buffer around each one. Clearing or filling inside a wetland or its buffer without approval is one of the fastest ways to get a stop-work order. The county may require a wetland delineation by a qualified biologist before it will act on your permit.
Streams and fish habitat
Creeks, seasonal drainages and ditches that connect to salmon streams carry buffers under the ordinance. Working in the water itself, or changing how it flows, also brings in the Washington Department of Fish and Wildlife, which issues a Hydraulic Project Approval for work in or near state waters. Replacing a culvert on a fish-bearing stream is a good example. That is a planned job with a permit in hand, not something to knock out on a dry weekend.
Steep slopes and geologically hazardous areas
Much of the county is glacial till sitting on clay, and the bluffs along Port Townsend, Discovery Bay, Marrowstone Island and Hood Canal move. The ordinance flags slopes over a set steepness [VERIFY current slope threshold], mapped landslide areas and erosion hazard areas. Cutting into the toe of a slope or piling fill on top of one can start a slide. That is why the county often asks for a geotechnical report from a licensed geologist or engineer before it approves grading there. If you are still deciding whether to buy a sloped lot, a site evaluation before you close is money well spent.
Shorelines
Lots on saltwater, lakes and larger rivers fall under the county’s Shoreline Master Program, a separate set of rules layered on top of the critical areas code. Shoreline jurisdiction reaches inland from the water’s edge, so a lot that is not on the beach can still be inside it. Clearing, grading and bulkhead work in that zone need a shoreline permit or an exemption letter before you start.
When does grading by itself need a county permit?
Jefferson County has adopted building and grading code that sets thresholds for how much you can cut or fill without a permit. The rules generally look at four things: how deep the cut is, how deep the fill is, whether the fill will support a structure, and whether the work changes a drainage course. Small cuts and fills below the thresholds are exempt. Anything bigger needs a grading permit, and larger volumes can also trigger a State Environmental Policy Act (SEPA) review. [VERIFY: current Jefferson County cut and fill depths and volumes that trigger a grading permit and SEPA review.] We leave the numbers out on purpose. Thresholds change, and a wrong number on a web page is worse than a five-minute call to DCD.
What is the one-acre stormwater rule?
If your project will disturb one acre or more of ground, and stormwater from the site could reach a ditch, creek or the bay, you need coverage under the Washington Department of Ecology Construction Stormwater General Permit. That is a state permit, separate from anything the county issues. Smaller lots count if they are part of a larger common plan of development, such as a short plat where each lot is under an acre but the whole project is not.
Coverage means filing a Notice of Intent with Ecology, publishing a public notice, writing a Stormwater Pollution Prevention Plan and having a certified erosion control lead inspect the site while work is active. Ecology charges an annual permit fee [VERIFY current fee]. Plan on roughly a month from filing to coverage [VERIFY current Ecology processing time], so this is not a permit you pull the week before the machines arrive. Under an acre, you still have to keep mud on your lot. Silt fence, straw wattles and a rocked construction entrance are standard on any winter job we do, and if the site has a water problem to begin with, drainage is usually the first thing to fix.
Port Townsend city limits or Jefferson County: which office do you call?
Where your lot sits decides who you talk to.
- Inside Port Townsend city limits: the City of Port Townsend Development Services Department handles building, clearing and grading permits. The city has its own critical areas code and tree conservation rules that can apply to removing trees on a city lot. [VERIFY current city clearing, grading and tree permit triggers.]
- Everywhere else in the county, including Cape George, Kala Point, Chimacum, Port Hadlock, Irondale, Port Ludlow, Quilcene and Brinnon: Jefferson County DCD.
The line is not always where people think. Plenty of addresses with a Port Townsend mailing address sit outside the city and fall under the county. Check the parcel on the county’s online map or ask either office. Our Port Townsend page covers the city side in more detail.
What about septic, drainfields and Environmental Health?
Septic is its own track. Jefferson County Environmental Health reviews on-site septic systems, and your drainfield and its reserve area are protected ground. You cannot clear, grade, drive over, park on or fill on top of a drainfield or the reserve area set aside for its replacement. Wells need to stay 100 feet from any drainfield, including the neighbor’s, and there are setbacks from property lines, foundations and surface water as well. Before we grade a pad or cut a driveway, we ask for the septic as-built or the site evaluation so we know where those areas are. If you are planning a new system, your septic designer and your excavator should be talking to each other early.
Does cutting trees need a permit too?
Brush and small trees on a home site usually do not. Merchantable timber can. If you are harvesting trees to sell, or clearing forest land to build on, the Washington Department of Natural Resources may require a Forest Practices Application, and converting forest land without the right approval can put a six-year building moratorium on the parcel. Inside Port Townsend, the city’s tree rules apply on top of that. Our land clearing crew can tell you when a job has crossed from brush into timber.
What can your excavator decide for you, and what can’t they?
An experienced operator can read a lot from a walk around the lot. We can tell you where the ground looks wet, where a bank is likely to move, whether a project is close to an acre, and whether the job looks like it needs a permit. What we cannot do is issue the permit, decide where a wetland boundary is, sign a geotechnical report or promise that the county will approve something. Those calls belong to DCD, Ecology, a biologist or an engineer. A contractor who says “don’t worry about it” on a lot with a creek is putting your property at risk, not theirs.
Who pulls the permit?
The property owner is responsible for the permit in the end, and either the owner or the owner’s agent applies. [VERIFY: whether Eaglemount applies for grading permits as the owner’s agent, or the owner applies and Eaglemount supplies the site plan and grading details.] Either way, we help with the parts a permit technician will ask about: a site sketch, cut and fill quantities, where the spoils go, and the erosion control plan.
How long does a permit take, and what does it cost?
Simple grading permits with no critical areas issues move fastest. Anything that needs a wetland delineation, a geotechnical report or a shoreline permit takes longer, because you are waiting on a consultant first and county review second. [VERIFY: typical Jefferson County DCD turnaround for a stand-alone grading permit and for critical areas review.] County permit fees come from the county’s fee schedule [VERIFY], and consultant reports are billed separately by the consultant. Our on-site estimate is free. Permit paperwork and drawings, when you want us to handle them, are billed from [YOUR PRICE].
What happens if you clear or grade without a permit?
Code enforcement in Jefferson County usually starts with a complaint from a neighbor or an inspector driving by. From there you can get a stop-work order, a notice of violation, fines [VERIFY current amounts] and an order to restore the site. Restoration is the expensive part. Replanting a wetland buffer or rebuilding a slope costs far more than the permit would have. Unpermitted grading also shows up later, when you try to sell, refinance or pull a building permit for the house.
When should you call Eaglemount?
Call at the idea stage, before you have paid for a survey or a set of plans. A lot walk with Dusty costs you nothing and often saves a wasted trip to the permit counter. We handle site prep and grading, land clearing and retaining walls across Jefferson County, and we are used to working alongside the county, septic designers and geotechs. If you already have a permit in hand, send it over and we will build the job to match it. Request an estimate and tell us the parcel number or address, and we will tell you which of the rules above we think apply.
Questions we get asked
Do I need a permit to clear brush on my own lot in Jefferson County?
Usually no, as long as the lot is flat and dry and you are clearing blackberries, scotch broom, small alder and similar brush without moving much soil. You do need county review if any of that brush is in a wetland, a stream buffer, on a steep slope or in shoreline jurisdiction. Cutting merchantable timber to sell can also require a Washington DNR forest practices application. When in doubt, call Jefferson County DCD before you start.
What is the Critical Areas Ordinance?
The Critical Areas Ordinance is Chapter 18.22 of the Jefferson County Code. It protects wetlands, streams and fish habitat, geologically hazardous areas such as steep and slide-prone slopes, frequently flooded areas and aquifer recharge areas, plus a buffer around each one. If any part of your clearing or grading falls inside a critical area or its buffer, the county reviews the project first, even when the work would otherwise be too small to need a permit.
Who pulls the permit, me or the excavator?
The property owner is responsible for the permit, and either the owner or the owner's agent files the application. [VERIFY: whether Eaglemount applies for grading permits as the owner's agent or the owner applies and Eaglemount supplies the site sketch, cut and fill quantities and erosion control plan.] Either way, we help with the parts the permit technician will ask about, and we will not start grading on a lot that needs a permit until it is issued.
How long does a Jefferson County grading permit take?
It depends on whether critical areas are involved. A simple grading permit on a flat lot with no wetland, stream, slope or shoreline issue is the fastest path. [VERIFY: current Jefferson County DCD turnaround for a stand-alone grading permit.] Projects that need a wetland delineation, a geotechnical report or a shoreline permit take longer because you wait on the consultant first and the county second. The Ecology stormwater permit for one acre or more adds its own timeline on top of that.
What happens if I grade without a permit?
You risk a stop-work order, a notice of violation, fines [VERIFY current amounts] and an order to put the site back the way it was. Restoration is the expensive part. Replanting a wetland buffer or rebuilding a cut slope costs far more than the permit would have. Unpermitted grading also surfaces later, when you sell, refinance or apply for a building permit for the house and the county compares the lot to its records.
