Parks & Recreation
PARKS & RECREATION
Key Assets: Whatcom County is genuinely home to Mount Baker, a 10,781-foot stratovolcano and the second-highest peak in Washington, which holds the world record for the most snowfall recorded in a single ski season – an astonishing 1,140 inches (95 feet) during the winter of 1998-99 at Mount Baker Ski Area, still recognized as an unofficial world record. The Mount Baker Wilderness spans nearly 120,000 acres within the Mount Baker-Snoqualmie National Forest. Bellingham itself, nicknamed the “City of Subdued Excitement,” hosts Western Washington University and Whatcom Falls Park, a 241-acre park with four waterfalls running through the heart of the city. The county sits on the unceded traditional territory of the Coast Salish Peoples
Notes: Mount Baker’s world-record 1,140-inch single-season snowfall is a genuinely extraordinary and well-documented natural superlative, among the most striking facts covered anywhere in this project.

About Whatcom County
Whatcom County is Washington’s eighth most populous county and the 288th most populous in the United States, covering 2,107 square miles from the Canadian border south to the Skagit County line, and from the San Juan Islands-facing coast east to the North Cascades wilderness.
Bellingham (population ~93,000, the county seat) is one of the Pacific Northwest’s most consistently celebrated livable cities – a college town with a vibrant arts and outdoor culture anchored by Western Washington University (WWU) (enrollment ~16,000). Bellingham’s position on Bellingham Bay with views of the San Juan Islands and the North Cascades gives it an extraordinary natural setting. The city’s Fairhaven neighborhood – a Victorian-era village district with independent shops, restaurants, and a ferry terminal serving the San Juan Islands – is one of the most distinctive neighborhood commercial areas in Washington. Boundary Bay Brewery and a thriving craft beer scene reflect Bellingham’s progressive, outdoor-oriented culture.
Lynden (population ~16,000) is a distinctly Dutch-American community in the Nooksack River valley – settled by Dutch immigrants in the late 19th century, Lynden maintains strong Dutch Reformed church culture, dairy farming heritage, and a windmill at the center of its downtown that symbolizes its heritage.
Ferndale (population ~14,000) is a rapidly growing community along I-5 between Bellingham and the Canadian border – significant industrial and residential development including a major BP refinery complex that is one of Whatcom County’s largest employers.
Blaine and Birch Bay anchor the county’s Canadian border communities – Peace Arch State Park and the Peace Arch monument spanning the US-Canada border are iconic landmarks, and the Peace Portal Plaza outlet mall has historically attracted Canadian shoppers before exchange rate and retail changes altered that pattern.
Mount Baker – a 10,781-foot stratovolcano in the county’s eastern Cascade section – anchors the county’s ski and wilderness recreation economy. Mt. Baker Ski Area holds the world record for snowfall in a single season (1,140 inches in 1998–99).

Probate & Estate
Losing someone and having to deal with courts and paperwork at the same time is hard. This section won’t make that easier, but it should tell you what to expect, what it costs, and where to go – so at least you’re not walking in blind.
Where to go
Whatcom County Superior Court 311 Grand Avenue, Suite 301, Bellingham, WA 98225 (360) 778-5560
Whatcom County was founded March 9, 1854, named for Chief Whatcom, in Washington’s northwest corner along the Canadian border, county seat Bellingham. Washington has NO separate probate court and has NOT adopted the Uniform Probate Code – probate is handled through the Superior Court in each county, under Title 11 RCW.
Step 1: figure out which path applies
Washington probate is entirely discretionary – the law does not require a probate proceeding to be filed after a death, regardless of whether there was a will. Probate is typically pursued only when the decedent owned real property titled solely in their name, or personal property exceeding the small estate threshold.
Small Estate Affidavit (RCW 11.62.010) – available when the decedent’s entire probate estate does not exceed $100,000 (personal property only, not counting the surviving spouse’s community property interest), and at least 40 days have passed since death. No court filing is required – the successor presents the sworn affidavit directly to whoever holds the asset. All debts must be paid or provided for first.
Nonintervention Powers (RCW 11.68) – Washington’s signature alternative to full court-supervised probate. If the estate is solvent, the Superior Court MUST grant the personal representative nonintervention powers upon request (unless the will specifically forbids it). Once granted, the representative can sell, mortgage, and distribute estate property, and ultimately close the estate by filing a Declaration of Completion – all without further court orders, notice to beneficiaries, or hearings.
Full/Supervised Administration – required only when nonintervention powers are denied or not sought, typically in contested or insolvent estates.
TEDRA (Trust and Estate Dispute Resolution Act, RCW 11.96A) – Washington’s framework for resolving probate, trust, and estate disputes.
Step 2: filing for administration
The person seeking to serve as personal representative files a petition with the Whatcom County Superior Court Clerk’s Office, along with the original will (if any) and a certified death certificate.
The court appoints the personal representative and issues Letters Testamentary (with a will) or Letters of Administration (without one).
The personal representative petitions for nonintervention powers, which the court must grant if the estate is solvent (unless the will forbids it).
Once granted, the representative pays debts, manages and distributes property, and notifies creditors, without further court supervision.
The estate is closed by filing a Declaration of Completion.
What it costs
Filing fees and probate costs vary by estate complexity; confirm current Whatcom County Superior Court fees directly.
Washington HAS a state estate tax, separate from any small estate affidavit or nonintervention process. For deaths on or after July 1, 2026, the applicable exclusion amount is $3,000,000 (RCW 83.100.020), with rates from 10% to 20%. There is NO portability between spouses.
The federal estate tax exemption is far higher, at $15,000,000 for a 2026 death.
