Grays Harbor County, WA -- North Beach, at the Mouth of the Copalis River. Not the San Diego Neighborhood of the Same Name.

Pacific Beach, WAA Cabin Town Built Over a Cold War Submarine-Listening Post

Pacific Beach, Washington is a small, unincorporated Grays Harbor County community on the "North Beach" stretch of Washington's outer coast, roughly 15 miles north of Ocean Shores along State Route 109 and just north of Griffiths-Priday Ocean State Park at the mouth of the Copalis River. It shares a name with the far larger, far more famous Pacific Beach neighborhood of San Diego -- covered separately on this site -- and the two have nothing else in common: this Pacific Beach is a quiet, low-density vacation-cabin community with a 2020 Census population of 280, part of Grays Harbor County's unincorporated North Beach corridor rather than an incorporated city or a San Diego neighborhood. What most write-ups skip entirely is the town's actual origin story: a beachfront resort hotel built in the early 1900s that the U.S. Navy took over in 1942 for anti-aircraft training, that the Air Force ran as a Cold War radar station in the late 1940s, and that the Navy then rebuilt into a classified Sound Surveillance System (SOSUS) station tracking Soviet submarines until 1987 -- a facility that, decommissioned, is today a military-and-DoD-family recreational resort occupying a real share of the town's oceanfront. That single fact shapes almost everything a buyer needs to understand about this market, and it's the throughline for both pages linked below.

Defining Local Fact
A former Cold War Navy submarine-surveillance (SOSUS) station, decommissioned in 1987, is now a military/DoD-family-only oceanfront resort occupying a meaningful share of the town's shoreline lodging

What Pacific Beach, Washington Actually Is

Start with the disambiguation, because it matters for search results and for a buyer's own due diligence: this Pacific Beach is a small unincorporated community in Grays Harbor County on Washington's rugged, sparsely developed outer Pacific coast -- not the dense, well-known Pacific Beach neighborhood of San Diego, California, which this site covers as a separate market (pacific-beach-ca-ca). The two share nothing but a name. Washington's Pacific Beach sits on the "North Beach" stretch of coastline north of Grays Harbor itself, along State Route 109, in a corridor that also includes Ocean Shores, Oyhut, Copalis Beach, Moclips, and the private planned resort community of Seabrook. It sits immediately north of Griffiths-Priday Ocean State Park, a 364-acre state park at the mouth of the Copalis River, and its beach falls within the "Mocrocks" razor-clam management zone the Washington Department of Fish and Wildlife uses for the stretch of coast running from the Copalis River north to the Quinault Indian Nation's reservation boundary near the Moclips River. Before 2010, Pacific Beach was counted as part of the Moclips census-designated place; it became its own separately tracked CDP with the 2010 Census, and its most recently confirmed official population is 280 residents at the 2020 Census -- a genuinely tiny number that should recalibrate expectations for everything from transaction volume to civic infrastructure.

The town's actual history reads more like a Cold War case file than a typical beach-resort backstory. The first homesteader arrived in 1862, and by 1904 a resort developer named Dr. Edward Lycan was building out what became the Pacific Beach Hotel, which opened in 1906 fronting a stretch of beach reported at nearly two miles long. A 1915 fire destroyed the original building; it was rebuilt and had grown, by 1930, into a 50-room hotel with 25 additional cabins, drawing guests that reportedly included the actor Frederic March. That civilian resort era ended abruptly in 1942, when the U.S. Navy took over the property as an anti-aircraft training center, installing gun positions on the beach itself and using the former hotel as barracks. The Air Force ran a temporary Cold War radar station on the site starting in 1948; after the Air Force left, the Navy returned and built something considerably more consequential -- a classified Sound Surveillance System (SOSUS) installation used to monitor Soviet submarine movement in the Pacific, which remained in operation until 1987.

When SOSUS was decommissioned in 1987, the site didn't return to civilian hands -- it was converted into a Navy Morale, Welfare and Recreation (MWR) resort and conference center, operating today as "Navy Getaways Pacific Beach" (also listed as the Pacific Beach Resort and Conference Center), open to active-duty and retired service members, Department of Defense employees, and their families rather than the general public. The property underwent a multi-million-dollar renovation of its 30 oceanfront cottages in 2010 and now also offers hotel rooms, suites, and an RV park and campground on the ocean bluff. For a buyer evaluating Pacific Beach's real estate and rental economics, this is not a footnote: a genuine share of the town's best oceanfront lodging inventory is federal property operating outside the civilian real estate and short-term-rental market entirely, which changes the comp set and the competitive landscape here compared with a fully open-market resort town of similar size.

Beyond the Navy resort, Pacific Beach's population figures illustrate a real limitation of small-town data generally: the 2020 Census count of 280 is the most reliable official figure this research found, but American Community Survey-based estimates for the same community vary wildly depending on source and year -- one dataset puts the 2019-2023 five-year estimate at 46 residents, while another shows a 2023 single-year figure declining from 76 to effectively 0. None of those numbers should be read as more accurate than the decennial Census count; they're presented here specifically so a reader understands why any "current population" claim for a town this small deserves skepticism rather than being treated as settled fact.

Griffiths-Priday State Park, Razor Clams & What There Actually Is to Do

Griffiths-Priday Ocean State Park sits directly at Pacific Beach's southern edge, at the mouth of the Copalis River -- a genuinely large park for the area at 364 acres, with a reported 8,316 feet of ocean shoreline plus another 9,950 feet of freshwater shoreline along the Copalis River and adjacent Connor Creek. Its centerpiece is the Copalis Spit, a small peninsula that functions as a refuge for migratory shorebirds. The park's origin is a genuinely specific, sourced story rather than a generic "beautiful park" claim: Washington's State Parks and Recreation Commission accepted a 128-acre donation at the site on July 19, 1958, under the will of Judge Austin E. Griffiths, who had died in 1952; the will specified the park be named for his wife Ella Montgomery Griffiths and his foster parents Philip and Ann Priday, the couple he emigrated with from England in 1872. Today the park supports picnicking, fishing, clam digging, beachcombing, birdwatching, mountain biking, and seasonal gray whale viewing, and it functions as Pacific Beach's de facto front yard for anyone buying here specifically for beach access.

The other defining local activity is razor clamming, which is a genuine driver of the North Beach's small tourism economy rather than an incidental pastime. Pacific Beach sits within WDFW's "Mocrocks" razor-clam beach zone, one of the state's primary open-dig areas, and clam-season weekends bring a real, if modest, bump in demand for the area's motels, restaurants, and vacation-rental inventory up and down the North Beach corridor. For dining and lodging beyond the Navy's military-only resort, most visitors and residents rely on nearby Moclips (home to the long-running Ocean Crest Resort) and the newer, privately developed planned community of Seabrook a short distance north -- Seabrook is itself a notable local landmark as the area's dominant civilian-market resort draw, and it matters for a Pacific Beach buyer's own market data too: Zillow's own home-value tracking groups Pacific Beach together with Seabrook under a single combined "Seabrook-Pacific Beach" regional index rather than reporting the two separately, a real data wrinkle covered in more depth on the real-cost page.

Property Tax
Grays Harbor County's effective property tax rate runs roughly 0.87% of assessed value as of 2026, with a county-wide range of about 0.8%-1.2% depending on which special taxing districts serve a given parcel -- see the real-cost page for worked dollar examples and the honest caveat that this is a county figure, not a Pacific Beach-specific one.
Home Prices
Search-synthesized figures for Pacific Beach itself conflict meaningfully -- one aggregator's own numbers show both a roughly $429,620 median home price and a separate $930,000 median listing price for what it calls "the priciest city in Grays Harbor County." This page states that contradiction honestly rather than picking one number; see the real-cost and investment-outlook pages for the full picture and why it's unusually hard to pin down here.
State Tax Structure
Washington levies no personal income tax, but it does charge state sales tax (6.5%) plus a Grays Harbor County local add-on, combining to roughly 8.9%-9.1% depending on the specific taxing district -- a real difference from no-sales-tax coastal states covered elsewhere on this site.
Flood & Tsunami Exposure
Pacific Beach and neighboring Copalis Beach are both explicitly named on Washington's newest Cascadia-subduction-zone tsunami hazard and evacuation maps; a standard homeowners policy does not cover flood or tsunami damage, and Washington flood-insurance premiums are commonly cited in a roughly $396-$1,500/year statewide range. See the real-cost page for the full, honest breakdown.

Independent research. No ads. No sponsored listings. This is a pilot "thin market" build (hub + 2 topic pages) for a very small, lower-priority destination, not the site's full 22-page research format. Nearly every primary-source domain this research tried to fetch directly this session -- Wikipedia, HistoryLink.org, Washington State Parks (parks.wa.gov), the Grays Harbor County website, GraysHarborTalk, NOAA, Zillow, DataUSA, and several insurance-guide and resort-history sites -- was blocked by this session's network egress policy, so every fact below comes from search-result synthesis rather than a directly re-fetched, re-verified primary page. Facts used: search-synthesized Wikipedia and HistoryLink.org content on Pacific Beach's founding (1862 first homestead; Dr. Edward Lycan's 1904-1906 resort build), the Pacific Beach Hotel (1906 opening, 1915 fire and rebuild to 50 rooms + 25 cabins by 1930, Frederic March as a reported guest), and its 1942 Navy anti-aircraft, 1948 Air Force radar, and Navy SOSUS (operational until 1987) military history; Navy MWR's own "Navy Getaways Pacific Beach" / Pacific Beach Resort and Conference Center listings (via Campendium, TheDyrt, and militarycampgrounds.us) for the site's current military/DoD-only recreational use, 30 cottages, and 2010 renovation; Washington State Parks and Washington Trails Association content on Griffiths-Priday Ocean State Park's 364 acres, shoreline footage, the 1958 Judge Austin E. Griffiths bequest, and permitted activities; the Washington Department of Fish and Wildlife's Mocrocks razor-clam beach zone definition; Point2Homes, washington-demographics.com, and a 2020 Census citation for Pacific Beach's population (280 official 2020 Census count; conflicting, unreliable ACS-based estimates of 46 and a 76-declining-to-0 figure, both disclosed rather than resolved); Zillow's own combined "Seabrook-Pacific Beach WA" home-value region grouping (confirmed by its listed region URL, though the current index figure itself could not be fetched); Calcuris and Ownwell-style aggregator citations for Grays Harbor County's 2026 effective property tax rate (~0.87%, range ~0.8%-1.2%) and county median tax bill ($2,441/year on a $279,500 home, a county figure, not Pacific Beach-specific); Avalara and SalesTaxHandbook for Washington's state sales tax (6.5%) and Grays Harbor County's combined local rate (~8.9%-9.1%); betterflood.com-sourced Washington flood-insurance premium range ($396-$1,500/year, statewide); Washington DNR/Emergency Management and Spokesman-Review reporting (via search synthesis) confirming Pacific Beach and Copalis Beach are named on Washington's newest Cascadia-subduction-zone (M9.0 scenario) tsunami hazard and evacuation maps; and Grays Harbor County's own short-term-rental framework (Ordinance 469, adopted March 22, 2022; County Code 17.60.020; governed by RCW 64.37) via search-synthesized county planning-department content. Genuine, disclosed gaps: this research could not directly confirm a current, address-specific Pacific Beach home sale price, property tax bill, or insurance quote; the $429,620 median-home-price and $930,000 median-listing-price figures cited for Pacific Beach come from the same secondary aggregator and conflict with each other in a way this research could not resolve or independently verify; no Pacific Beach-specific shoreline erosion-rate data was found (unlike some other coastal markets on this site); water/sewer infrastructure (municipal vs. well-and-septic) for Pacific Beach specifically was not confirmed; and the exact acreage and amenities of the separate, smaller "Pacific Beach State Park" (distinct from the larger Griffiths-Priday State Park referenced above) could not be verified this session because its source page was blocked.
