Adapting in an Evolving World

2021 Annual Report

Director's Message

Snohomish County Public Works staff members continue to pride themselves on being nimble, diligent, and thorough in maintaining and improving vital infrastructure and finding improved ways of waste disposal and recycling. However, the past two years have brought many changes for everyone due to the pandemic. Through it all, Public Works employees used their skills to adapt and evolve. That evolution has touched everything we do, from operational processes and acquiring materials, to the way we interact with the public and more. I am proud to say we have continued to deliver our services and projects this year despite some sizable bumps in the road.

Supply Chain Challenges

One hurdle this year was obtaining critical materials to complete projects. Scarce materials included everyday items such as paint for road striping and prefabricated culverts for surface water projects. With an abundance of patience and working with our contractors and vendors, we accomplished our goals on time or created a back-up plan with minimal delays in crossing the finish line. 

Department Reorganization

One major evolutionary change in 2021 was the re-organization of the Surface Water Management (SWM) division from Public Works and into a brand-new department. The creation of the Department of Conservation and Natural Resources (CNR) brings together Parks and Recreation, SWM, Energy and Sustainability and Agriculture under the same roof to better steward natural resources. We continue to partner in preserving existing and building new culverts, maintaining high quality surface water infrastructure, and easing environmental burdens on our customers.

Weather Related Emergencies

Safety took on a somewhat new look this past summer as a record heatwave sent temperatures well into the triple digits. Infrastructure issues followed, such as buckling sidewalks and liquifying asphalt. Our Road Maintenance crews proved they are ready for anything, getting emergency repairs completed within days. Road Maintenance crews were also busy in 2021 plowing nearly 100,000 miles of county roads during snow and ice storms in February and December.

Communications Evolution

With the need to keep our customers and residents informed in a prompt manner, Public Works expanded its footprint in social media and digital platforms. We increased our social media presence by creating Public Works-centric Facebook and Twitter accounts. Virtual public meetings and recordings became the norm. Important issues, such as improvements to the busy 84th St NE corridor and updates to the Solid and Hazardous Waste Management Plan, were presented in online public meetings.

Major Awards

Our online outreach was rewarded with the top award in government communications. The 2019 Pathways for Active Transportation Online Open House took first place in the 2021 3CMA Savvy Awards for best interactive communications. Hermes Creative and American In-House Design awards were also received for signage and printed materials. Snohomish County's Solid Waste division was honored in 2021 as a Call2 Recycle Top 100 Leader in Sustainability.

However, awards don’t come much bigger than winning the American Public Works Association Washington State Project of the Year. The 2021 award for projects under $5 million was bestowed on the South Machias/Machias Cutoff project, which was completed in June 2020 and located east of Lake Stevens. 

Public Works was awarded a $22.1 million federal grant to replace the Granite Falls Bridge 102 from the U.S. Department of Transportation’s Rebuilding America’s Infrastructure with Sustainability and Equity (RAISE) grant program during 2021. The grant is one of the largest in the country and totals more than all the grant dollars received for our road projects in 2020 ($17.1 million).

These accomplishments and so many more are highlighted throughout this annual report. However, it is the employees of Snohomish County Public Works who make these accomplishments possible with their hard work, dedication, and ability to adapt to changes. When you get to the final page you will see what I see – our staff of more than 500 work every day towards improving the quality of lives of each Snohomish County resident.

Sincerely,

Kelly Snyder, MPA

Public Works Director

About Public Works 

Public Works is the largest department in the Snohomish County government and responsible for approximately 1,600 miles of county roads, more than 200 bridges and manages about 200 traffic control signals. The department also processes more than 560,000 tons of garbage per year. Its mission is to focus on safety and mobility while practicing fiscal responsibility and preserving the environment. The department budgeted for 559 full-time positions during 2021 and made 102 new full-time hires. In addition to its full-time employees, the department also employed: 

All divisions within Public Works maintain services and work throughout the year. Below are the five different divisions and their directors/managers. 

Litter Wranglers

One of the most popular Snohomish County programs, the  Litter Wranglers , returned in 2021 to maintain the county’s natural beauty. The program was put on hold during 2020 to determine the safest way to move forward during the pandemic. The Litter Wranglers experienced great success during their fourth overall year, collecting nearly 6,000 bags of garbage and cleaning more than 800 road miles.  

The Litter Wranglers find many different things discarded by the side of the road like this TV entertainment center.

The Litter Wranglers solicit citizen tips about excessive litter sites. The crew prioritizes each site and then visits them in the most efficient order. 

The five-person crew of seasonal employees also saves construction and maintenance crews valuable hours by cleaning a work site prior to their arrival, allowing them to work solely on maintaining vital infrastructure.

Each Litter Wrangler is trained as a flagger and learns how to avoid dangerous conditions in the field.

Zoom in and select each road segment to see the quantity of bags collected and miles of road cleaned. 

To zoom in and out, use the + and - buttons in the lower right corner. The color corresponds to the number range of bags collected. 

Adopt-A-Road

You can help maintain Snohomish County’s natural beauty by participating in the  Adopt-A-Road program . It forms partnerships between volunteer groups and Snohomish County Public Works to keep roadsides free of litter and promote community pride. Participants can be families, church groups, businesses, neighborhood groups and more. 

Public Works has multiple programs that help maintain Snohomish County's natural beauty.

Weather Response 

Twice for Snow and Ice

Mother Nature kept Public Works staff busy in 2021 with some extreme weather emergencies. The year started off and ended with snowstorms in February and December that blanketed Snohomish County with snow and ice. Road Maintenance crews worked to plow predetermined priority routes that are primary arterials and main service routes for emergency responders. Once those roads had been cleared, crews moved on to secondary and tertiary routes.

Snohomish County manages more than 1,600 miles of roadway, but because of heavy and frequent snow, crews returned repeatedly to the primary routes to clear new fallen snow before moving to secondary routes and local streets.

Plows not only push the snow out of the way but also put down sand for traction on the remaining ice.

Overall, crews cleared nearly 100,000 miles of county roadway with up to 38 plows out on the streets at any time during the event to keep roads open during both storms. They used nearly 2,200 tons of sand, more than 10,000 tons of sand/salt mix, and 2,300 gallons of anti-icer.   

The Communications staff issued 18 press releases and nearly 60 social media posts leading up to and during the emergency response to keep Snohomish County residents informed. 

Heatwave

In a rare occurrence, a summer heatwave buckled sidewalks and roadways, and liquified some chip seal due to multiple-day, triple-digit record heat in late June. Heat causes concrete to expand, and in extreme situations, overwhelm expansion joints. Damages around the county cost more than $191,000. The majority of the issues took place on Mountain Loop Highway near Granite Falls, Old Highway 99 near Silvana, Machias Rd near Lake Stevens, and Marine Drive in Tulalip. Road Maintenance crews were able to repair most of the damage within weeks of the heatwave. 

Record triple-digit heat buckled many sidewalks in Snohomish County during summer 2021.

Completed Capital Project 

180th St SE Improvement Project - Phase I

The unincorporated area between the cities of Mill Creek and Bothell is one of the fastest growing in the entire county. The 180th St SE corridor runs east/west through the heart of this community and, along with the north/south corridors of 35th Ave SE and Seattle Hill Rd, are some of the main routes for navigating the southwest area of Snohomish County. 

 Phase I of the 180th St SE improvement project  was completed in 2021. The project widened the road from three lanes to five, along with adding sidewalks, bike lanes, curbs, and gutters, from State Route (SR) 527 to 23rd Ave SE. It also improved the health of the two creeks in the area by relocating the merger of Thompson Creek and Silver Creek from the north side of 180th St SE to the south side.

The project separated the creek crossings from one culvert into two, relocated Thompson Creek from the ditch channel along the north side of the road, diagonally under 180th St SE, where it merges with Silver Creek. This creates a more natural flow for Thompson Creek, made space for the street widening, and minimized the need for right-of-way acquisition from property owners.

The new fish-passable stream channel and culverts are the result of coordinated efforts with county staff, the Washington Department of Fish and Wildlife, the Army Corps of Engineers, and the Muckleshoot Tribe. 

New stormwater detention and treatment facilities were created as part of the 180th St SE - Phase I project.

The project also improved the health of Thompson Creek and Silver Creek.

Crews also rebuilt the traffic signals at 180th St SE and Brook Blvd and created new stormwater detention and treatment facilities, and planter strips. Project construction cost more than $10 million and was funded through a Public Works Trust Fund loan of $3 million, a $4 million grant from the Washington State Transportation Improvement Board, developer mitigation fees, and the rest was from the Snohomish County Public Works Road Fund. 

Snohomish County Public Works completed the expansion of 180 th  St SE (SR 527 to 23 rd  Ave SE) from three lanes to five during 2021.

Notable Projects in Progress

35th Ave SE Improvement Project - Phase II

Another important corridor in the southwest area of Snohomish County is the  35th Ave SE corridor . Public Works is improving the area between SR 524 and 180th St SE by adding bike lanes, center turn lanes, planter strips, sidewalks, and stormwater detention and treatment facilities. The corridor is an important north-south route for Snohomish County residents. The project will improve traffic flow and help ease congestion during busy morning and afternoon commutes. The addition of continuous center turn lanes will reduce delays caused by turning vehicles. 

The project is scheduled for completion in summer 2022.  Construction for this project will cost $8.9 million and Snohomish County received a Washington State Transportation Improvement Board grant of $5 million and a Public Works Board loan of $3 million for the project. The rest will be funded through the Snohomish County Road Fund and developer mitigation fees.

This new stormwater detention facility was constructed as part of the 35th Ave SE - Phase II project.

Index-Galena Rd Flood Damage Repair 

Index-Galena Rd is a route that maintains essential travel and emergency services in rural southeast Snohomish County and provides recreational access to parts of the Mt. Baker Snoqualmie National Forest and the Wild Sky Wilderness area. 

Heavy rains during 2006 severely impaired Index-Galena Rd. During the past 15 years, Public Works completed repairs on 10 of the 11 areas that were damaged and began construction on the  final site between milepost 6.4 to 6.9  in 2021. This portion of road was considered a total loss with significant portions of pavement, roadbed, and culverts damaged by the flooding. 

The work includes nearly one mile of reconstructed roadway, allowing the river channel to run where the old road was located, 16 culverts, one reinforced concrete box culvert, a new 180-foot-long bridge, geosynthetic reinforced slopes, structural earth walls, and removal of the asphalt from the damaged roadway and other man-made materials. It is scheduled to reopen in 2023.

Crews will continue to work on the Index-Galena project through 2022 and are scheduled to reopen the road in 2023.

The repairs and reconstruction will cost $23 million. Funding for this project is provided by the Federal Highway Administration Emergency Relief Funds, Federal Highway Administration Federal Lands Access Program Funds, Washington State County Road Administration Board (CRAB) Rural Arterial Program Funds, and Snohomish County Road Funds.  

North Creek Trail – Phase I 

 The North Creek Regional Trail  will become part of a coordinated regional system eventually connecting with the Sammamish River Burke-Gilman Trail in Bothell and the Snohomish County Regional Interurban Trail near McCollum Park. This segment will be located west of Bothell-Everett Highway (SR 527), east of North Road and north of 208th Street SE.

The North Creek Trail project will be completed in three phases.

Public Works began construction on Phase I from SR 524 to Sprague Dr during spring 2021 at a construction cost of $8 million. Public Works was awarded a $1 million construction grant from the Washington State Recreation and Conservation Office. Phase I is schedule to be completed in fall of 2022.

Jim Creek Rd Culvert Replacement

Snohomish County began replacing the existing culvert in the 19900 block of  Jim Creek Rd , east of Arlington, during summer 2021. The existing six-foot by six-foot concrete culvert was deemed a fish-passage barrier. The project replaces the culvert with a single 21-foot steel arch culvert. This project is scheduled to be completed in summer 2022.

This new 21-foot steel arch culvert was installed on the Jim Creek Rd project east of Arlington.

Snohomish County Road Safety Plan 

Public Works staff in the Transportation and Environmental Services division and consultants prepared a draft Snohomish County Road Safety Plan (RSP) in 2021. This document, to be completed in 2022, will provide a blueprint for implementing measures to reduce roadway crashes in an objective and data-driven way. The goal of the project is to bring the rate of fatalities and serious injuries down to zero on unincorporated roads.  

The RSP is aligned with the Washington State Department of Transportation’s Vision Zero plan – Target Zero: Washington State Strategic Highway Safety Plan, which highlights the importance of data-driven collision reduction strategies. 

A key element of the RSP is the collaboration with several partners including WSDOT, the Sheriff’s Office, Fire Districts, the County Council, and others. These partners formed the Safety Advisory Committee which was a forum to share and learn from many perspectives. 

Snohomish County is prioritizing this RSP as fatal and serious injury crashes continue to affect lives across the county, especially the lives of vulnerable users such as pedestrians, bicyclists, and motorcyclists.  

Public Works will use the data, tools, and partnerships outlined in the plan, along with a sustained commitment to fund and implement road safety strategies, in future infrastructure improvements around the county. 

Pavement and Sidewalk Improvements 

Paving and Chip Seal  

Each year Public Works evaluates the county road network to develop the most cost-effective, multi-year plan for preserving and maintaining all county roads. The department is dedicated to maintaining and improving pavement to preserve the county’s roadway network condition and investment.  

 The Asphalt Overlay and Chip Seal program  included work on a total of 58 roads, including eight roads in north county and 50 roads in south county during 2021. Road Maintenance crews chip sealed approximately 38 miles of county roads and placed a full-length, full-width asphalt overlay on 3.7 miles. Meanwhile, contractors were hired and paved 5.1 county miles. 

Paving – Paving, or overlay, focuses on preserving pavement while it is still in fair condition by placing a new layer of asphalt over the existing asphalt. Preserving a road in this manner will maintain an appropriate level of safety, minimize damage caused by water seeping into the roadway base, and preserve the roadway investment in the most cost-efficient manner. A typical asphalt road has a serviceable life of 15-30 years depending upon location, traffic volumes, weather, and truck / heavy vehicle usage. 

Crews overlay a section of road as part of the paving and chip seal program implemented in 2021.

Some roads are identified as needing existing asphalt ground-off prior to placing the new asphalt. Grinding of existing pavement is sometimes needed to match the existing elevation, pre-level the surface if rutting or depressions are present, or to remove surface distress such as cracking. In addition, grinding is usually required along the curb or gutter line. A tack coat is placed for the purpose of creating a good bond between new asphalt and the existing surface. Then hot-mix asphalt is placed on the tack coat and the material is compacted by rollers. Several passes are sometimes necessary to achieve the required compaction. 

Chip Seal – Chip seals are a commonly used and a cost-effective way to preserve and extend the life of a road by 7-10 years. Road Maintenance crews repaired potholes, sealed cracks and/or pre-leveled the road surface by applying a layer of hot asphalt. Crews placed crushed rock along the shoulders and striped or placed temporary markers where necessary. A layer of asphalt oil (chip binder) was applied to the road when weather was sufficiently warm and dry. This step was immediately followed by a layer of crushed rock, which created a “chip seal.” The chips were pressed into place by a roller and the road was ready to use. 

Crews chip seal a section of road as part of the county's paving and chip seal program in 2021.

Kayak Point Rd 

Public Works repaved  Kayak Point Road  and 140th St NW during summer 2021. The total length of the project is approximately 2.3 miles. Prior to the paving contract, Snohomish County crews also performed pavement repairs at some locations, ensuring a smoother drive for residents. This project is part of the Rural Roads Preservation program and is funded by the Federal Surface Transportation Program and the Snohomish County Road Fund. The total was under $1.5 million. 

Approximately 2.3 miles of Kayak Point Rd was paved in 2021.

Airport Rd – Accessible Pedestrian Signal Devices and Ramps 

Public Works installed Accessible Pedestrian Signal (APS) devices and upgraded six ramps along Airport Rd at the intersections of 100th St SW and 94th St SW in Everett. The upgrades bring these intersections in line with the Americans with Disabilities Act and were coordinated with the ADA Public Right-of-Way (ADAPROW) Advisory Committee. Upgraded ramps include detectable warning surfaces and APS pushbuttons that prompt audio cues to help pedestrians who are vision impaired to cross the intersections safely. The $203,000 project was paid for through the Snohomish County Road Fund. 

Upgraded ramps on Airport Rd include detectable warning surfaces.

Damson Rd Damson Rd Sidewalk Extension 

Sidewalk gaps along the west side of  Damson Rd  across from Hilltop Elementary School in Lynnwood were filled in by Public Works in 2021. The project improves pedestrian access for residents and students of Hilltop Elementary School. Funding for the $192,000 project came from the Snohomish County Road Fund. 

The Damson Rd sidewalk improvements are across the street from Hill Top Elementary School.

Curve remediation – HFST  

The Curve Remediation project completed in 2021 improves driving conditions on the curves of 20 separate rural roads. Public Works applied High Friction Surface Treatment to the pavement of six separate roads to give vehicles more traction. Road Maintenance crews also replaced 216 existing signs and added 360 signs to improve driving conditions at selected locations. They are replaced to improve reflectiveness for nighttime driving and the signs that have reached the end of their useful life are sent to a local metal recycler. 

The project was funded by a $1.3 million Highway Safety Improvement Project grant. The Washington State Department of Transportation selected the project to receive the grant funding from the Federal Highway Safety Improvement Program. 

Road and Bridge Maintenance Projects  

The Road Maintenance division routinely performs road and bridge repairs. Those projects include performing subgrade, sidewalk, shoulder, culvert, bridge deck, and ditch repairs, along with the removal of downed or dangerous trees in the county right-of-way, and many other tasks to keep the county’s infrastructure in peak performance.  

 Bridge Inspections and Maintenance 

During 2021, inspections of county bridges were performed by the Engineering Services Bridge Team on 108 county bridges. The county also provided inspection services for 23 city-owned bridges under interlocal agreements. The county had three Under-Bridge Inspection Truck (UBIT) inspections and performed three underwater inspections that involved divers to examine piers below ordinary water levels.

Road Maintenance crews perform regular bridge cleaning and maintenance repairs if needed.

Public Works inspects all county bridges at least every two years in accordance with the National Bridge Inspection Standards (NBIS). A small number of bridges are inspected more frequently due to certain features that require additional monitoring. Some bridges require specific access assistance, equipment and professional services during the inspection process, such as UBIT inspections. To perform UBIT inspections, the county contracts the Washington Department of Transportation (WSDOT). If there is work to be done on the bridges the Road Maintenance Bridge Team will conduct the repairs.

The Snohomish County bridge crew inspects the Wes Smith Bridge 122 during 2021.

Bridge Facts 

County road and bridge teams inspect and inventory 206 bridges that provide continuity between more than 1,600 miles of county roads. This bridge network consists of:  

  • 10 culverts 
  • 23 steel bridges 
  • 29 multi-material bridges 
  • 38 timber bridges 
  • 106 concrete bridges 

Bridges are a big part of Snohomish County's transportation infrastructure and are inspected by the Engineering Services division.

 

Culverts and Drainage Improvements 

Snohomish County Public Works partners with the Surface Water Management division of the department of Conservation and Natural Resources to maintain the county’s surface water infrastructure. Most people do not notice culverts unless something goes wrong as most are usually out-of-sight and out-of-mind. The purpose of culverts and drainage infrastructures is to collect, treat, and convey stormwater runoff and safely convey stream flow. Culverts on streams need to be passable to aquatic species and mimic the natural system as much as possible. They also prevent the water from pooling and flooding roads and private property. 

Culvert and drainage projects in 2021 improved fish passage, replaced rusted and failing infrastructure, and reduced flooding. Most older culverts were designed without regard to fish passage. Others became barriers over time through deterioration or changes in flow due to increased rainfall or land use. Replacing fish-barrier culverts opens additional habitat that is an important component of protecting and restoring fish populations. 

Descriptions of four large projects are shown below. All project locations, including eight more smaller projects, are shown on the map. Funding was provided through the Surface Water Management Utility Fund unless otherwise noted. 

268th St NW Culvert Replacement (near Stanwood)  

Public Works replaced two culverts, a 24-inch and an 18-inch, with a single 18-foot span, 10-foot rise, and 70-foot-long culvert on  268th St NW  during August 2021. The project, which relieves a barrier to fish passage, cost $715,000. 

The new culvert under 268th St NW.

Mann Rd/Haystack Creek Culvert Replacement   

Twin culverts on  Mann Rd/Haystack Creek  were replaced with one 20-foot span by 6-foot rise concrete box culvert and completed in September 2021. The project relieved a barrier to fish passage and helps reduce road flooding. The road elevation was also raised approximately 1,400 lineal feet to accommodate the culvert. Ditches and driveway culverts were installed on the south side of the roadway. Guardrail was installed adjacent to the stream culvert. Construction cost $1.2 million.  

Mouse Creek – Phase II  

Public Works completed the second phase of the  Mouse Creek  Drainage Improvement Project in the fall of 2021. Crews excavated 500 feet of sediment build-up downstream of Sauk Prairie Rd and Mouse Creek Bridge 631. Phase I and Phase II efforts have re-established the historic stream channel, which helps reduce road flooding and improve the passage for Coho and other species of fish. Phase II of the project cost approximately $90,000.  

180th St SE Drainage Improvements  

Drainage improvements were performed along  180th St SE  in the North Creek area to reduce driveway/roadway flooding from the ditch on the south side of 180th St SE. 

Crews upsized the conveyance system including road and driveway culverts and replaced a cross culvert at 83rd Ave SE. Driveways were brought up to current design requirements, where applicable. The project was performed during August and September 2021 at a cost of $492,000. 

Drainage improvements on 180th St SE completed in 2021.

Solid Waste Maintenance and Upgrades  

Solid Waste is constantly working to make the customer experience more enjoyable and efficient at all facilities. To achieve these goals, the division performs regular maintenance and upgrades. During 2021, Solid Waste completed three major projects that will prevent unscheduled shutdowns from equipment failure and move commercial customers and residents through the facilities in a more expedited fashion. 

Just like any mechanically based operation, solid waste facility tools incur wear and tear over time. Solid Waste performed some large maintenance tasks in 2021 to maintain peak processing power, standards, and safety.  All maintenance and upgrades are paid for through public solid waste processing fees collected at county facilities.

Tipping Floor Repairs at ARTS 

In April, Solid Waste conducted repairs to the concrete tipping floor at the Airport Road Transfer Station (ARTS). The tipping floor is where mostly commercial customers park to unload large quantities of refuse for collection at the facility. The floor can wear down over time with all the weight of the mostly large trucks and heavy Solid Waste equipment. Other maintenance was also performed at the same time, such as customer lane restriping.  

The ARTS tipping floor incurs a lot of wear and tear over time. Repairs were performed during 2021 to keep the facility maintained.

Compactor Replacement at NCRTS 

Snohomish County replaced a compactor that has reached the end of its useful life at the North County Recycling and Transfer Station (NCRTS) during October. The compactor crushes refuse brought to the facility by customers so that it can be more efficiently transferred to a landfill.   

The new compactor arrives at the North County Recycling and Transfer Station in October 2021.

Solid Waste Automated Billing 

Making sure customers can move through the Solid Waste facilities in the most expedited and safe manner is a priority for Solid Waste staff. One change that frequent commercial customers experienced this year was the implementation of automated billing. Commercial customers with Solid Waste accounts were able to sign up for this service and receive a card for their drivers to scan as they entered and left the transfer stations. These cards replaced the time-consuming practice of visiting the cashier each time they dropped off refuse. The system then tracks how much that individual business owes the county and bills them in regular intervals. This process moves the trucks through the facility quicker and reduces wait times for all customers. 

Residential customers stop at the scale house to weigh their vehicle prior to and after dumping their load at the transfer stations.

Public Works DEI Plan 

Public Works values the diverse perspectives and lived experiences of our staff and the people of Snohomish County. The department is committed to the principles of equal employment opportunity and envisions a workplace culture that welcomes our differences, gives staff a sense of belonging, and addresses inequalities with an atmosphere of equity. 

During 2021, Public Works developed the Diversity, Equity and Inclusion (DEI) Plan in partnership with the Public Works DEI Task Force that included staff from each division and Surface Water Management, data2insight (an independent consulting firm), and the Public Works Management Team. 

The DEI Plan includes details on the planning process, DEI Framework, history and context for the plan, goals, implementation, and attachments with resources. Public Works staff will be involved in a variety of ways including but not limited to training, work groups, and evaluation. 

Implementation of this four-year plan in 2022 will include measurable, ambitious goals; and a mechanism for ongoing measurement and evaluation that will facilitate collective learning and continuous improvement. 

Public Works aims to provide staff with a work environment free of discrimination and harassment, and that reflects the diversity of our residents. The implementation of this DEI Plan will be consistent with Public Works' vision, mission, values, the department's strategic plan, and with the direction of the County Executive. 

Roads Divisions 

Whether it is clearing the roads during a winter snowstorm, constructing road improvements during the summer, planning road improvements to accommodate growth, or coordinating traffic light synchronization throughout the year, three divisions of Public Works keep residents moving. 

The  Engineering Services  Transportation and Environmental Services , and  Road Maintenance  divisions work together to maintain and improve more than 1,600 miles of roadway and more than 200 bridges. Snohomish County manages about 200 traffic control signals. About half of those signals are within and managed for local cities.

For more on the Roads Divisions  click here .  

 

Solid Waste Division

 The Solid Waste Division , in coordination with many service providers, oversees all county programs and facilities for the disposal of household hazardous materials, garbage and recycling. The division works with local garbage haulers that transport curbside waste collection to transfer stations for consolidation and shipment to a landfill in eastern Washington. 

Residents can also utilize in-person Solid Waste services during visits to one of the county’s three transfer stations, three drop boxes, or the Household Hazardous Waste Drop-off Station.

Financing

Programs and Capital Projects

The funding of Snohomish County Public Works relies on many partnerships. The county submits applications to federal and state agencies to be awarded grants. This enables the county to leverage local taxes, service charges, and fees paid by residents, with those grant dollars in order to complete more projects and provide more services.  

Road Fund – Funding for road construction, planning, maintenance and operations of the county’s network of roads is provided by the Snohomish County Road Fund. The fund includes a property tax levy of $1.05 per $1,000 (2021 rate) of assessed valuation on unincorporated property. Snohomish County received approximately $69 million in 2021 road levy revenues. The county budgeted $9 million in gas tax revenues for 2021.   

Solid Waste Funds – Funding for Solid Waste is primarily generated from facility customer fees and sale of recyclables. 

Grant Funds – Snohomish County Public Works acquires grants in order to stretch local tax dollars and produce more services and projects.  

Did you know? 

Snohomish County was also awarded one of the biggest grants in its history in 2021 for the Granite Falls Bridge Replacement project from the U.S. Department of Transportation’s Rebuilding America’s Infrastructure with Sustainability and Equity (RAISE) grant program. The $22.1 million RAISE grant for Bridge 102 was the largest award in Washington state in 2021 and one of the largest in the country. Construction is targeted to begin in 2025. 

Outreach

Public Works takes pride in having good communication with residents, whether it is during a pandemic, a big snow and ice storm, or during summer construction projects. 

Through the use of open houses, social media, mailers, informational telephone lines, email bulletins, and other forms of communication, the county relies on resident input to form our processes and give us feedback on how to improve our services.
