If you have been waiting for fast internet in Mason County, the map is getting smaller. Mason County Public Utility District No. 3 has been connecting fiberhoods across the county through the winter and into spring 2026 — and two of the county’s biggest expansion projects are in their final stages right now.
In March alone, PUD 3 lit up three neighborhoods: Pacific Ridge connected on March 18, Arcadia Shores on March 25, and Fern Way on March 26. Each connection means residents who may have been running on dial-up-equivalent speeds — some areas were getting as little as 1.5 Mbps — are now able to access gigabit service: symmetrical 1000/1000 Mbps fiber, the same kind of speeds most Seattle households take for granted.
Cloquallum Communities: 680+ Homes, October 2026 Target
The Cloquallum Communities Fiberhood is one of the largest single projects in PUD 3’s fiber buildout, serving more than 680 customers across the greater Cloquallum area. This project is funded through an American Rescue Plan Act (ARPA) grant that PUD 3 was awarded in late 2023 through the Washington State Broadband Office.
The main fiber backbone was completed in July 2025. Individual home connections began in September 2025 and are expected to wrap up by October 2026. In a significant milestone, the Cloquallum Fiberhood — along with Wivell Road and Loertscher Road fiberhoods — officially connected on February 10, 2026, meaning the first Cloquallum homes are already online. The October 2026 date marks full project completion for the entire service area.
Three Fingers Fiber: Federal ReConnect Grant, Final Connections Underway
The Three Fingers Fiber Project was funded through a federal ReConnect Program grant awarded to PUD 3 in early 2020. Construction of the mainline distribution network is complete. PUD 3 is now in the customer connection phase, working through individual service hookups with an April 2026 project completion deadline.
Like all PUD 3 fiber, Three Fingers runs on an open-access network — meaning multiple internet service providers can deliver service over the same fiber cable. Residents aren’t locked into one provider. Unlimited, symmetrical gigabit speeds (1000/1000 Mbps) are available from participating retail providers.
What PUD 3’s Fiber Network Means for Mason County
Mason County is largely rural, and rural broadband access in Washington State has historically lagged well behind urban and suburban areas. PUD 3’s aggressive fiberhood buildout — which uses a neighborhood-based sign-up model to determine construction priority — has been one of the most significant public infrastructure investments in the county in years.
The combination of federal ReConnect grants, ARPA funding, and the state Washington Broadband Office partnership has allowed PUD 3 to extend fiber to communities that private carriers have never reached and likely never would on a commercial basis. For residents who have been working from home on spotty satellite connections or driving to the library to upload files, these connections are genuinely life-changing.
For Mason County as a whole, reliable broadband is increasingly a prerequisite for economic development — attracting remote workers, supporting small businesses, enabling telehealth, and making rural property competitive with suburban alternatives.
Is Fiber Coming to Your Area?
PUD 3 uses a fiberhood model: neighborhoods that meet a minimum sign-up threshold get prioritized for construction. If your neighborhood hasn’t been connected yet, the way to move it up the list is to sign up and encourage neighbors to do the same. Check current project status and sign up at pud3.org.
For residents in areas already built out, connection to your home requires scheduling an installation with PUD 3 and then selecting a retail internet service provider. Visit PUD 3’s service zone map to check your address.

Frequently Asked Questions
Which Mason County neighborhoods got fiber in March 2026?
PUD 3 connected Pacific Ridge on March 18, Arcadia Shores on March 25, and Fern Way on March 26, 2026. The Cloquallum Fiberhood and adjacent Wivell Road and Loertscher Road fiberhoods also came online in February 2026.
When will the Cloquallum Communities Fiberhood be fully complete?
The project targets full completion by October 2026. More than 680 homes and businesses in the Cloquallum area are included. Individual connections began in September 2025 and are being installed in stages through the October deadline.
What speeds does PUD 3 fiber provide?
PUD 3’s fiber network supports symmetrical gigabit service — 1000 Mbps download and 1000 Mbps upload — through its participating retail internet providers. This is a significant upgrade for areas that previously had speeds as low as 1.5 Mbps on legacy connections.
How is PUD 3 funding its fiber expansion?
The buildout is funded through multiple sources: a federal ReConnect Program grant (Three Fingers Fiber), an American Rescue Plan Act grant through the Washington State Broadband Office (Cloquallum Communities), and PUD 3’s own fiberhood program funded through customer sign-up revenue. No property taxes are being raised for this expansion.
What is PUD 3’s open-access fiber model?
Unlike most private ISPs, PUD 3 builds and owns the fiber infrastructure but allows multiple retail service providers to deliver internet, TV, and phone service over the same cable. Customers choose their preferred provider. This prevents monopoly pricing and gives Mason County residents more options than they typically have in rural areas.
How do I get fiber internet through PUD 3 in Mason County?
Check your address on PUD 3’s service zone map at pud3.servicezones.net. If your area is built out, you can schedule an installation with PUD 3 and then select a retail internet provider. If your area hasn’t been built yet, signing up on the fiberhood waitlist helps push your neighborhood toward the construction threshold.
