Five conditions that shape a Washington site plan
Washington layers a state framework over local administration, and that framework decides more of the site plan than it does in most states. Five conditions change what a Washington plan must show and how fast it moves.
1. The urban growth area line decides what a parcel can become
The Growth Management Act (GMA, RCW 36.70A) requires the most populous and fastest-growing counties, and their cities, to designate Urban Growth Areas (UGAs) and adopt comprehensive plans with consistent development regulations [6]. Urban-scale development (dense residential, most commercial, public sewer) is directed inside UGAs; land outside is held to rural densities and resource-land protections, with no urban services and heightened critical-areas and water-availability review [6]. GMA also requires transportation concurrency and authorizes impact fees for roads, parks, schools and fire under RCW 82.02.050 [6]. The first line of a Washington site data table is whether the parcel sits inside the UGA.
2. Local permit decisions run on statutory clocks
SB 5290, enacted in 2023 and amending Chapter 36.70B RCW, requires GMA-planning jurisdictions to issue a final decision within 65 days for permits that need no public notice, 100 days for permits that need public notice, and 170 days for permits that need both notice and a hearing [1]. The clock runs from the determination of completeness and excludes applicant-caused delays, and it replaced the historic 120-day clock [1]. Building permits are excluded, and jurisdictions over 20,000 population report annual permitting performance to Commerce [7]. Seattle implemented SB 5290 through Ordinance 127300, effective November 24, 2025 [8]. Washington also vests a project to the regulations in force when a complete application is filed: when the 2021 building codes took effect on March 15, 2024, complete applications submitted before that date vested to the 2018 codes [9]. Completeness starts the decision clock and fixes the rules, so the first submittal carries weight. Read more on why your permit clock starts later than you think.
3. The architect seal line sits at 4,000 square feet
RCW 18.08.410 sets out what is not the practice of architecture. In the Attorney General's words, that covers "design work for residential buildings with four or fewer dwelling units, design work for farm buildings, design work for buildings not exceeding four thousand square feet, and interior design services not affecting public health or safety" [2]. AGO 2022 No. 3 adds that "Washington law provides no bright line rule for distinguishing between design documents that must be completed by an architect and those that must be completed by an engineer," and that "It is primarily up to local building officials to determine which types of documents are required or sufficient" [2]. Submittal checklists therefore vary, and some jurisdictions require a stamped site plan or civil set below the state architect exemption.
4. Stormwater and critical areas come off the buildable area first
Ecology requires Construction Stormwater General Permit coverage when a project disturbs one or more acres and discharges to surface waters, or is part of a larger common plan disturbing one acre or more [3]. Ecology's manuals set nine Minimum Requirements, from MR1 Stormwater Site Plan to MR9 Operation and Maintenance, generally triggered at 2,000 sq ft of new plus replaced hard surface for the lower requirements and 5,000 sq ft for the higher ones, which include runoff treatment and flow control [10]. Low impact development must be used "where feasible," and on-site stormwater management (MR5) is a compulsory pathway [10]. Every GMA jurisdiction must also adopt critical areas ordinances protecting wetlands, fish and wildlife habitat conservation areas, streams, geologically hazardous areas, frequently flooded areas and critical aquifer recharge areas, using "best available science," with wetland buffers keyed to category (I to IV) and habitat score under the Washington State Wetland Rating System [11]. Buffers, and the area the engineer of record needs for flow control and treatment, come off the site before the layout is drawn. See how detention and retention reshape a site.
5. Shorelines and water supply are state gates
Shoreline jurisdiction under the Shoreline Management Act (RCW 90.58) extends 200 feet landward from the ordinary high water mark, plus associated wetlands and floodplains [4]. Development over the substantial development threshold, $8,504 effective July 1, 2022 (WSR 22-11-036), needs a Substantial Development Permit, and shoreline conditional use permits and variances require Ecology approval [4]. Inland, RCW 19.27.097 requires evidence of an adequate water supply before a building permit issues [12]. The 2016 Whatcom County v. Hirst decision halted some rural development; ESSB 6091 (effective January 19, 2018) then removed individual impairment review for permit-exempt wells in most basins, with the Skagit and Yakima basins treated differently [12].
Approval layers: state, county and city
| Layer | Body | What it decides | Authority |
|---|---|---|---|
| State | Department of Ecology | Construction stormwater coverage; approval of shoreline conditional uses and variances; water resource rules | [3, 4, 12] |
| State | State Building Code Council | Building, fire and energy codes, with state amendments | RCW 19.27 [13] |
| State | WSDOT | Access connection permits on managed access highways outside cities and towns; traffic impact review | RCW 47.50 [14] |
| State | Department of Health | Transient accommodation licenses | RCW 70.62 [15] |
| State | DNR and WDFW | Aquatic lands leases; Hydraulic Project Approvals for work in or near water | RCW 79.105; RCW 77.55 [16] |
| County | County departments (King County Local Services, Snohomish PDS, Pierce Planning and Public Works, Clark Community Development) | Zoning, site plan review, plats, critical areas and SEPA in unincorporated areas | County codes |
| City | City planning and building departments | Their own codes inside municipal boundaries | City codes |
| Courts | Superior court under LUPA | Review of land use decisions; petition filed and served within 21 days | RCW 36.70C.040 [5] |
Jurisdictions typically type permits from Type I (ministerial, staff, no notice) through Type V (legislative: rezones and comprehensive plan amendments), with Type III quasi-judicial decisions made by a Hearing Examiner after a hearing. Pierce County codifies tiers in PCC 18.30.020: site plan review and short plats are Tier 2 administrative decisions, while preliminary plats, conditional use permits and variances go to a Hearing Examiner hearing at Tier 3 [17]. Everett defaults land use decisions to REV I minor administrative review, with REV II and III for preliminary plats and discretionary actions (EMC 15.02.060) [18]. In Chandrruangphen v. City of Sammamish (February 12, 2026), the Washington Supreme Court held that the three-day mailing extension does not apply to decisions sent by email, so the LUPA clock runs from the send date, and that service must be on the properly designated official [19].
Who prepares and seals what
Washington does not put a blanket seal on every site drawing. It sets thresholds, and then leaves the final call to the local building official [2].
| Document | Who seals it | Rule |
|---|---|---|
| Building design above the RCW 18.08.410 exemptions | Washington-registered architect, or engineer where the work is engineering | RCW 18.08.410; AGO 2022 No. 3 [2] |
| Engineered stormwater (MR1 Stormwater Site Plan, flow control, treatment), public infrastructure, significant grading, structural design | Professional engineer | Ecology CSWGP [3] |
| Boundary and topographic surveys, records of survey, plats and short plats | Professional land surveyor | RCW 58.09; RCW 58.17; WAC 332-130 [20] |
| A licensee's final documents | Seal, signature and date of the licensee "who prepared or directly supervised the work" | WAC 196-23-020 [20] |
| A licensee's preliminary documents | Stamped, but need not be signed or dated | WAC 196-23-020 [20] |
RCW 18.43.070 requires plans, specifications, plats and reports prepared by a registrant to be signed, dated and stamped [21], and under WAC 196-23-010 every Washington PE or PLS uses a board-authorized seal [22]. The CSWGP SWPPP and stormwater site plans are engineering deliverables [3].
Our preliminary site plan is unsealed: the layout, buildings, internal roads, drive aisles, parking, pads and units, and the yield, with a site data table that carries UGA status, zoning, density against the cap, setbacks, buffers and parking required against provided. You use it to choose a site, raise capital, brief a lender, get a contractor's price and take it to a pre-application conference (see where unsealed site plans are accepted). The engineer, architect and surveyor of record then build the sealed set on it. That is the same split a site plan consultant or site plan architect works within; for the general rules, see who prepares a site plan, do I need an architect for a site plan and preliminary vs final site plan.
Statewide overlays
| Overlay | Rule | Source |
|---|---|---|
| Building codes | 2021 editions, effective March 15, 2024; local amendments may not reduce minimum performance standards | RCW 19.27 [13, 23] |
| Construction stormwater | Coverage at one acre with discharge to surface waters; apply at least 60 days before discharging; CESCL inspections on sites of one acre or more | Ecology CSWGP [3] |
| Erosivity waiver | Available for one to five acres of disturbance; not available above five acres | Ecology CSWGP [3] |
| Minimum Requirements | MR1 to MR9, triggered at 2,000 and 5,000 sq ft of new plus replaced hard surface, plus a 1-acre disturbance threshold | SWMMWW; SWMMEW [10] |
| Municipal stormwater permits | Phase I and II permits push the manual into local codes, so the MRs bind private projects | Ecology [24] |
| Critical areas | Mitigation sequencing (avoid, minimize, mitigate); buffers by wetland category | GMA; Ecology [11] |
| Shorelines | 200 feet from the ordinary high water mark; $8,504 threshold; some fish-passage and habitat projects exempt | RCW 90.58; RCW 90.58.147 [4, 16] |
| Water supply | Evidence of adequate water before a building permit | RCW 19.27.097; RCW 90.94 [12] |
| On-site septic | Administered by local health jurisdictions | WAC 246-272A |
| SEPA | Environmental checklist; DNS, MDNS or EIS | RCW 43.21C; WAC 197-11 [25] |
The 2021 codes were delayed twice from July 1, 2023, first to October 29, 2023 and then to March 15, 2024, partly because of the 9th Circuit's California Restaurant Association v. Berkeley decision [26].
SEPA. WAC 197-11-800 exempts minor new construction below thresholds. GMA-planning jurisdictions may adopt flexible thresholds by ordinance: residential exemptions at any level between 4 and 30 dwelling units in the UGA, and commercial buildings between 4,000 and 30,000 sq ft; where no ordinance is adopted, the minimum levels apply [25]. The base exemption covers four detached single-family units, four multifamily units and agricultural structures up to 10,000 sq ft, excluding feedlots [27]. Raising thresholds takes 60-day notice to tribes, agencies, Ecology and the public, plus WSDOT consultation [25]. Each jurisdiction's adopted threshold decides whether a project needs a checklist, and a threshold determination and its appeal can add months.
State highway access. WSDOT is the access permitting authority for managed access highways outside incorporated cities and towns. Managed access highways have five classes, from Class 1 (most restrictive) to Class 5 (least restrictive), and four access connection permit categories; limited access highways do not receive access connection permits [14]. A traffic impact analysis is triggered under Design Manual Ch. 1130.09 when a proposal adds 10 or more AM or PM peak-hour trips to an individual approach or intersection leg, or 25 or more to a state highway segment or intersection, or degrades the level of service below the applicable threshold [28]. Local jurisdictions set their own thresholds inside their boundaries.
Ground and climate. The Cascadia Subduction Zone and crustal faults, including the Seattle Fault, put site class, liquefaction analysis and geotechnical reports on larger projects. Mount Rainier lahar hazard zones drive Pierce County planning. Puget lowland glacial till, perched groundwater and landslide-prone coastal bluffs drive geologically hazardous areas review. West of the Cascades, high rainfall drives the stormwater regime; east of the Cascades, wildfire risk is significant and the Eastern Washington manual governs.

Asset registries
| Asset | State layer | Local layer |
|---|---|---|
| RV parks | Water supply and sewage disposal reviewed by the local health jurisdiction [46]; on-site sewage systems under WAC 246-272A | Local zoning |
| Campgrounds and glamping | Camps under WAC 246-376 [47]; three or more units rented for under 30 days are transient accommodations under WAC 246-360 [48] | Clallam County treats glamping cabins as an unlisted use needing a conditional use permit (CCC 33.05.010) [49] |
| Hotels | DOH license under RCW 70.62 and WAC 246-360 for three or more lodging units rented for under 30 days [15] | Set locally |
| Fuel retail | Ecology UST program under WAC 173-360A, effective October 1, 2018; a license for each tank (WAC 173-360A-0200) [50] | Set locally |
| Car washes | Ecology Pub. 95-056 washwater practices [51] | Spokane requires oil/water separators and sand traps [52] |
| Marinas | Shoreline permits, DNR aquatic lands lease (RCW 79.105), WDFW Hydraulic Project Approval (RCW 77.55), typically USACE Section 10/404 [16] | Set locally |
| Self storage and industrial | SEPA exemption for commercial buildings set between 4,000 and 30,000 sq ft by each jurisdiction [25] | Local zoning, critical areas and stormwater review |
RV parks and campgrounds. No state RV park design standard (density, site size or separation) has been verified for Washington; water supply and sewage disposal are reviewed by the local health jurisdiction [46]. The RV park site plan, campground site plan and glamping site plan hubs carry the layout standards from the states that publish them.
Fuel retail. Ecology's UST rule, WAC 173-360A, took effect October 1, 2018, replacing the repealed Chapter 173-360. Ecology regulates more than 8,500 tanks at more than 3,400 facilities, and installation and site assessment require certified service providers [50]. See the gas station site plan hub for canopy, dispenser and circulation layouts.
Car washes. Washington has no single statewide car wash rule; the constraint is washwater. Ecology Pub. 95-056 calls for a wash pad that extends at least 4 ft past the vehicle, grit traps inspected daily and cleaned at least weekly, and API separators cleaned above 3 in of oil, and storm-drain discharge may need an NPDES permit [51]. Those dimensions belong on the car wash site plan from the first draft.
Hotels and marinas. A hotel site plan answers to the DOH transient accommodation license [15]. A marina site plan needs shoreline permits, an aquatic lands lease, an HPA and typically a Corps permit [16]; see marina permitting across USACE, coastal and local overlays.
Growth, timelines and bottlenecks
Per OFM's April 1, 2026 estimates, over 62% of population growth occurred in the five largest metropolitan counties: Clark, King, Pierce, Snohomish and Spokane [53]. Franklin (2.6%), Adams (2.1%) and Benton (1.6%) were the fastest-growing counties by percentage, and the incorporated cities and towns reached 5,396,145, up 0.8% [53]. From April 2025 to March 2026 Washington added 41,000 housing units, 62% of them multifamily, and King County led with 14,160 new units, 35% of the state total [54]. Clark County grew by roughly 7,600 to about 550,000, second in the state for numeric growth [55].
The recurring stalls are SEPA threshold determinations and appeals; critical-areas review, with wetland delineations, buffers and mitigation reports from qualified professionals; stormwater review under the Minimum Requirements, especially LID feasibility and flow control; transportation concurrency and traffic impact analysis; and water or utility availability. Resubmittals most often follow incomplete stormwater site plans, missing geotechnical or critical-areas reports, and conflicts with the comprehensive plan or zoning. The first Annual Permitting Performance Report under SB 5290, released September 2025 and covering 2024, gives emerging benchmarks; early Pierce County data showed construction permits averaging well within the 120-day deadline, with some final subdivisions behind schedule [7].
Proof points
- Statutory clocks in force. Seattle Ordinance 127300 implemented SB 5290 effective November 24, 2025 [8].
- Strict appeal service. Chandrruangphen v. City of Sammamish, decided February 12, 2026, runs the 21-day LUPA clock from an email send date [19].
- Glamping by conditional use. A Clallam County Hearing Examiner decision treats glamping cabins as an unlisted use that needs a conditional use permit [49].
- Housing output. King County added 14,160 units in the year to March 2026, 35% of the state total [54].
- Code vesting. Complete applications filed before March 15, 2024 vested to the 2018 codes [9].
What the engineer of record adds
The preliminary plan fixes the program, the layout and the yield. The Washington engineer and architect of record add the MR1 stormwater site plan, the SWPPP, flow control and treatment design, grading, utilities and the structural and seismic design, and seal the permit set. The land surveyor adds the boundary, topography and any plat. Qualified professionals add the wetland delineation and critical-areas reports, and the geotechnical engineer adds the site class and liquefaction work. For the full scope, see site plan services; compare the neighboring state, Oregon, or see service areas and start a project.
Frequently asked questions
Do I need a licensed architect to stamp my site plan in Washington?
Not necessarily. Buildings of 4,000 sq ft or less, residential buildings with four or fewer dwelling units, and farm buildings are outside the statutory practice of architecture (RCW 18.08.410), but a local building official may still require sealed documents [2].
Can a drafter prepare a site plan in Washington?
Yes, for exempt structures and for work prepared under the direct supervision of a licensed professional who seals the final documents (WAC 196-23-020) [20]. The preliminary site plan is the unsealed draft the engineer and architect of record build the sealed set on.
When do I need a Construction Stormwater General Permit?
When the project disturbs one acre or more, or is part of a larger common plan disturbing one acre or more, and discharges to surface waters. Apply at least 60 days before discharging [3].
How long does a city or county have to decide a land use permit?
How long do I have to appeal a land use decision?
What is the shoreline permit threshold?
Development over $8,504 in cost or fair market value within 200 feet of a shoreline generally requires a Substantial Development Permit [4].
Is a pre-application conference mandatory?
It depends on the jurisdiction. It is mandatory in Clark County before a Type II or III submittal, for Spokane Valley commercial building applications, for most Spokane County land use applications and for a defined list in Bellingham; it is optional in Bellevue, Everett and Vancouver [35, 42, 41, 43, 44, 18, 37].
What triggers a traffic impact analysis on a state highway?
WSDOT treats a proposal as significant when it adds 10 or more AM or PM peak-hour trips to an individual approach or intersection leg, or 25 or more peak-hour trips to a state highway segment or intersection [28].
