Infrastructure & Broadband in Mason County
From fiber-optic broadband to road maintenance to failing septic systems, Mason County's infrastructure needs require strategic investment and responsible planning.
Building for the Future
Infrastructure is the backbone of a thriving community.
Infrastructure is the invisible backbone that supports everything else in a community — economic development, public safety, education, healthcare, and quality of life. In Mason County, that backbone needs significant attention. From the roads and bridges connecting rural communities to the broadband networks enabling modern commerce and education, our infrastructure has not kept pace with the demands of a growing and changing county.
The good news is that meaningful progress is being made. Mason PUD 3 has extended fiber-optic broadband to 51.4% of homes in the county, a remarkable achievement for a rural utility. The county has allocated $4.165 million for road projects in 2026 and secured a $1.5 million bridge award. But the scale of unmet need remains significant, with approximately 4,000 residents actively requesting broadband service and critical infrastructure challenges throughout the county.
One of the most pressing and often overlooked challenges is the county's aging septic infrastructure. With over 26,000 onsite septic systems — many installed decades ago and nearing the end of their useful life — Mason County faces a looming crisis that affects public health, water quality, and the ability to accommodate new development.

Challenges Facing Mason County
The Digital Divide
While Mason PUD 3 has achieved impressive progress with fiber-to-the-home reaching 51.4% of county residences, nearly half of homes still lack access to reliable broadband internet. Approximately 4,000 residents have actively requested service, and projects like the Cloquallum Fiberhood are working to reach underserved areas. Without broadband, families cannot fully participate in remote education, telehealth, or the modern economy. Small businesses and home- based entrepreneurs in unserved areas operate at a significant disadvantage.
Aging Road and Bridge Network
Mason County maintains hundreds of miles of roads and dozens of bridges that serve as the only connections for many rural communities. The $4.165 million allocated for 2026 road projects and the $1.5 million bridge award represent important investments, but the maintenance backlog continues to grow as infrastructure ages and traffic increases. Winter storms and heavy logging truck traffic take a particular toll on rural roads, and bridge weight restrictions can isolate communities and force long detours.
Septic System Crisis
Over 26,000 onsite septic systems serve homes and businesses throughout Mason County, and many are aging, failing, or inadequately maintained. Failed systems contaminate groundwater, streams, and marine waters, contributing to water quality problems in Hood Canal and other sensitive waterways. For individual homeowners, replacing a failing system can cost $15,000 to $40,000 or more — a devastating expense for families on fixed incomes. The Belfair sewer system investment addressed this issue in one growth area, but large portions of the county remain dependent on onsite systems.
Capacity for Growth
As Mason County grows, infrastructure must keep pace. New housing developments, commercial projects, and industrial facilities all require reliable water, sewer, power, broadband, and transportation connections. Without proactive infrastructure planning, growth is either blocked entirely or occurs in ways that strain existing systems and degrade service for current residents.
Karen's Approach to Infrastructure
Strategic investment that builds for the future while addressing today's needs.
Karen brings a financial planner's perspective to infrastructure: you have to think long-term, prioritize wisely, and make every dollar count. As a commissioner, she will work to ensure Mason County makes smart infrastructure investments that address critical needs today while positioning the county for sustainable growth.
Close the Broadband Gap
Karen will work to support Mason PUD 3's continued fiber expansion, advocate for state and federal broadband funding for rural areas, and explore innovative approaches like the Cloquallum Fiberhood model to bring connectivity to the nearly 4,000 households still waiting. Universal broadband access is essential for economic opportunity, education, and healthcare in the modern era.
Prioritize Road and Bridge Maintenance
Karen supports a data-driven approach to road and bridge maintenance that prioritizes safety-critical repairs and maximizes the value of every transportation dollar. She will work to pursue state and federal transportation grants and ensure that the county's road maintenance program addresses the needs of rural and underserved communities that depend on county roads.
Address the Septic Challenge
Karen will work to explore programs that help homeowners maintain, repair, or replace failing septic systems, including financial assistance for low-income families. She supports expanding sewer infrastructure in growth areas where it makes environmental and economic sense, building on the successful Belfair model while protecting the county's waterways and groundwater.
Maximize Grant Funding
Karen will work to ensure Mason County aggressively pursues every available state and federal infrastructure grant. From USDA Rural Development programs to state broadband funding to federal transportation and water quality grants, there are significant resources available for communities that prepare strong applications and demonstrate clear need.
Coordinate Infrastructure with Growth Planning
Karen supports aligning infrastructure investment with the county's comprehensive plan to ensure new development is supported by adequate roads, broadband, water, and sewer capacity. This prevents the costly pattern of development outpacing infrastructure that creates problems for both new and existing residents.
