Kinsman Road Project Completed 4 Months Early; Opens Next Week

By News Desk, News Partner , 

 Covering a half-mile of roadway in West Wilsonville, the $8.6 million extension is a “real win-win for the public,” city officials said.

WILSONVILLE, OR – From the City of Wilsonville: The City of Wilsonville announces that the new Kinsman Road extension that connects SW Barber Street to SW Boeckman Road is opening on budget and four months ahead of schedule during the week of Jan. 15.

In addition to providing another routing connection for travelers, construction of the roadway incorporated simultaneously other water- and sewer-installation infrastructure projects that resulted in reduced public disruption and costs.

Originally scheduled for completion in June 2018, the $8.6 million half-mile-long roadway segment, located between Villebois and the industrial westside of Wilsonville, connects two major arterials that greatly improves the city street-grid and provides increased connectivity for both freight and residential traffic.

The new Kinsman Road extension was constructed as a heavy-duty concrete roadway complete with sidewalks and bike lanes that also provides increased public access to the Wilsonville Transit Center, including SMART Central bus and Tri-Met WES commuter rail service.

City engineer Zach Weigel, PE, who oversaw the project, indicates that advance planning and permitting activities, favorable weather and well-coordinated government agencies and contractors contributed to the early completion of the project.

City Community Development Director Nancy Kraushaar, PE, said, “The Kinsman Road extension project is a real win-win for the public that provides new travel routing options, as well as reduced costs for additional major water and sewer projects.”

City engineers worked to combine $5.1 million of other public infrastructure projects with the long-planned road extension in order to more efficiently use taxpayer-funds. The Kinsman Road project included the installation of a $4.0 million segment of a major drinking-water pipeline and a $1.1 million sanitary sewer pipe. S

imultaneous construction of the road, Willamette Water Supply Program (WWSP) water pipeline and sewer project allowed various local governments to all save money and minimize disruption to the public by utilizing one contractor and sharing common costs, such as contractor mobilization, traffic control, permitting, project design, right-of-way acquisition and environmental protections that all three projects would have incurred if performed separately.

The Willamette Water Supply Program, a partnership between the Tualatin Valley Water District (TVWD) and the City of Hillsboro, installed nearly 3,000 feet of 66-inch diameter pipeline that is the first completed section of 30 miles of large-diameter water-supply pipeline from Wilsonville to Hillsboro and Beaverton.

The pipeline is made of half-inch thick steel with welded joints, a cement mortar lining inside the pipe, and a highly durable polyurethane coating on the outside. Future segments of the pipeline are to connect along Boeckman Road to the east and on Kinsman Road to the south of Barber Street.

The City also installed over 3,000 feet of new sewer line in the acquired road right-of-way that is designed to serve the regionally significant Coffee Creek industrial area now under development.

The Coffee Lake wetlands complex adjoins both sides of the Kinsman Road extension. The west side of the new roadway features an extra-wide sidewalk and benches for wildlife and habitat viewing. Fencing along the road and a series of wildlife corridor passages beneath Kinsman Road, including round and box culverts, were constructed to improve safety for both drivers and wildlife.

These details maintain wildlife corridors within an urban landscape and mirror the natural resource protection previously achieved with the Boeckman Road project that also crosses the wetlands.

The project design team was led by OBEC Consulting Engineers, and Emery and Sons Construction Group of Salem managed the construction project. The water-supply pipe was manufactured by Northwest Pipe Co., which specializes in large-diameter steel pipelines.

A total of 90 local jobs are estimated to have been sustained during the course of the 12-month-long project.

Funding for the combined $13.7 million road-sewer-water pipeline project came from City transportation and wastewater system development charges, federal/state funds (U. S. Dept. of Transportation Multimodal Transportation Enhance Program (MTEP) through the Statewide Transportation Improvement Program (STIP) and Surface Transportation Program Urban (STP-U)), and the ratepayers of the TVWD and City of Hillsboro.



Underground river: Pipeline to bring water to westside

North Portland company supplies large pipes for $1.2 billion Willamette Water Supply Program that us underway in Washington County

Westside suburbs are mounting a $1.2 billion project to take drinking water from the Willamette River, with a Portland company playing a major supporting role.

Northwest Pipe Co. has so far provided all of the pipe for the Willamette Water Supply Program, one of the largest public infrastructure projects ever undertaken in the region.

When it is completed, the project will draw water from the Willamette River in Wilsonville and provide it to communities in Washington County through more than 30 miles of pipe, a water treatment system, two reservoirs and numerous pumping stations.

Northwest Pipe, located in the Burgard Industrial Park in far North Portland, has won all three contracts awarded for the pipe so far. It is on track to produce 19,500 feet of pipe for the first three stages of the project. The sections ranges from 48 to 66 inches in diameter, and from 48 to 60 feet long.

A call to action: Imagine a ‘day without water’

by Mark Knudson and Kevin Hanway

Washington County residents can take practical steps to safeguard public safety in emergencies

Imagine: No water to drink, fight fires, water crops, shower, or flush the toilet. Some communities in America already have experienced how difficult it can be to go a day without our most precious resource: Water.

Oct. 12 is Imagine a Day Without Water — an opportunity to raise awareness and talk about the value and importance of water in all our lives.

This year, the U.S. has endured 49 separate weather, climate and flood disasters. These events have caused billions of dollars of damage and led to the second most disaster-laden season on record. The majority of these events severely affected water quality and availability.

For Tualatin Valley Water District (TVWD) and the city of Hillsboro, these disasters reinforce the importance of maintenance of water infrastructure and the need for investment in reliable and resilient water systems. Why? So we can restore access to high-quality, safe drinking water and water for fire protection as quickly as possible after an emergency.

Earthquakes are high on the list of natural disasters that can interrupt our drinking water supply. Communities often are without reliable, safe, water supplies following a large earthquake. Restoring water service to hospitals, schools, homes and businesses — as well as for firefighting — can sometimes take months. This is a critical threat to public health, public safety and the region’s economy.

The good news is some new infrastructure is coming.

TVWD and the city of Hillsboro are currently partnering to develop the mid-Willamette River at Wilsonville as an additional water supply source for Washington County by 2026. The Willamette Water Supply Program (WWSP) will design and build a water treatment plant, storage tanks, and more than 30 miles of large-diameter transmission pipeline traveling from Wilsonville to Hillsboro.

This new water delivery system is designed to withstand the impacts of a Cascadia earthquake or other natural disasters so that water service can be restored quickly and our communities can recover sooner. Not only will this new water infrastructure increase the resiliency and reliability of the region’s water supply, but the mid-Willamette River will also become an additional source of high quality water for both TVWD and the city of Hillsboro.

Primary goals of TVWD and the city of Hillsboro are to protect public health and provide customers access to quality water as quickly as possible after an emergency. In addition to their investments in the new WWSP water infrastructure project, TVWD and the city support these goals by investing in maintenance and upgrades of the treatment plants, pumps, pipes, and storage facilities that work seamlessly to deliver water to your tap. These water system facilities are managed by our highly skilled professional staffs who, like the systems they oversee, operate in the background of our busy modern lives. We also are industry leaders that work in partnership with other agencies on regional emergency planning and seismic preparedness.

However, depending on our public institutions to take care of us when disaster strikes isn’t enough. TVWD and the city of Hillsboro call all customers to action.

TVWD and the city of Hillsboro are dedicated to doing our part to strengthen and maintain water infrastructure to bring clean, safe water to customers in the aftermath of a major disaster.

City and TVWD officials encourage area residents to create an emergency response plan and compile personal emergency response kits, with water, food, a first-aid kit and other supplies necessary to keep you and your family going for a minimum of 72 hours.

We hope you will join us in reflecting on the value of water and preparing in advance so a day without water doesn’t become our reality.

Mark Knudson is the CEO of Tualatin Valley Water District and Kevin Hanway is director of the city of Hillsboro Water Department.

Hillsboro’s new water system is under construction

Hillsboro Tribune, Written by John William Howard Friday, October 06, 2017

“The Willamette Water Supply pipeline will eventually run from Hillsboro to the Willamette River in Wilsonville, supplying water to Hillsboro customers and the Tualatin Valley Water District, which serves more than 200,000 Washington County customers.”

The Willamette Water Supply pipeline is one of the most expensive infrastructure projects in Oregon.

As developers work to the lay the foundation for Oregon’s largest housing development south of town, a second set of crews have been laboring underground to install one of Oregon’s most-costly infrastructure projects.

The Willamette Water Supply pipeline will eventually run from Hillsboro to the Willamette River in Wilsonville, supplying water to Hillsboro customers and the Tualatin Valley Water District, which serves more than 200,000 Washington County customers.

The price tag for the 30-mile pipeline project is around $1.2 billion.

The project will take years to complete, but workers are currently digging a trench for the section of the pipeline slated to pass under Southeast Tualatin Valley Highway and follow Southwest Cornelius Pass Road all the way to Highway 26. On a tour of the site on Monday, a handful of workers in white hard hats scurried around a 48-inch pipe at the bottom of a deep pit south of TV Highway as steel plates plunged into the earth.

A few yards from the pit, a future extension of Cornelius Pass Road winds through the land where 8,000 homes and apartments will be built over the next decade. This is the Reed’s Crossing neighborhood, one of the large developments that make up South Hillsboro.

Hillsboro city officials say the pipeline project is not designed to quench the thirst of South Hillsboro, which is slated for completion around the same time as the pipeline. In June, Hillsboro Water Department Director Kevin Hanway told the Tribune the pipeline will supply water to Hillsboro residents for the next 50 years.

The city selected the mid-Willamette project over ideas to raise the level Hagg Lake and purchasing water from Portland, among other options.

Project officials say laying the pipeline allows the Hillsboro and TVWD to build infrastructure without tearing up newly-built roads, saving millions in construction costs.

“We’re building the pipeline before South Hillsboro is built,” said Andre Tolme, project manager. The project worked with the Oregon Department of Transportation to reconfigure the intersection of Cornelius Pass and TV Highway to cut down on lane closures, limiting the impact on drivers, Tolme said. The project will also coincide with a county widening project of Cornelius Pass Road north of TV Highway.

This is one of several such worksites along the path of the pipeline. In Sherwood, crews are blasting through a hillside to lay pipeline and extend Southwest 124th Avenue. They’ve already tunneled under railroad tracks, and are grinding rock for gravel infill used in other portions of the project.

Steve Clapper, a supervisor with the pipeline project, said crews have been blasting to clear some sections of roadway. The blasted rock is reused as roadbed to save on hauling costs.

“We’re keeping the material on site,” Clapper said.

Here, the pipeline is more than five feet across — tall enough to walk in. Each section of the pipe is 50 feet long, weighing in at 20,000 pounds. The pieces are welded together with the only joints at valve sections, which according to project officials, will have a better chance of withstanding earthquakes.

The majority of the money spent building the project is staying in the Portland Metro area, a major selling point for the project partners. According to project documents, the partners have spent $41.3 million on the project so far. Most of that has gone to 85 local contractors and businesses. Kerr Contractors is working on the 124th Avenue and South Hillsboro projects, the first two portions of pipeline construction.

Looking ahead

Beginning in 2018, crews are scheduled to continue pipeline extension from TV highway to Southeast Frances Street in Hillsboro. Construction from Southwest Farmington Road is set to begin in 2019.

The longest stretch of the pipeline, a 7.7-mile section southwest of Beaverton, runs from Farmington Road south to Bull Mountain, and should begin construction in 2018.

The project also calls for a water treatment plant and pump station, slated for construction in Sherwood beginning in 2022. Storage tanks will be built near Cooper Mountain Nature Park in Beaverton beginning in 2022, and along with the treatment plant, are among the final scheduled portions of the project set to wrap up in the first quarter of 2026.

Tolme said the project doesn’t call for a new intake facility on the Willamette River. The project can simply expand portions of the current facility, which is located just upriver of the Interstate 5 crossing in Wilsonville.

In Tigard’s future, Willamette water could be a must-have

The Times,  Written by Mark Miller, September 12, 2017

“The Tigard City Council expressed interest late last year in becoming a community partner in the Willamette Water Supply Program, a major infrastructure project spearheaded by the Tualatin Valley Water District and the City of Hillsboro.”

Since 1999, Tigard’s city charter has expressly forbid the city from using the Willamette River as a source for its drinking water supply without voter authorization.

But in the future, the president of the Tigard City Council suggested Tuesday, Sept. 12, Tigard may have no other option but to draw from the Willamette River as its water needs grow.

The Tigard City Council expressed interest late last year in becoming a community partner in the Willamette Water Supply Program, a major infrastructure project spearheaded by the Tualatin Valley Water District and the City of Hillsboro. While no formal agreements have been signed yet to make it official, under the terms presented at Tuesday’s meeting, Tigard would purchase a 10 percent share of an expanded water intake on the Willamette River — a capacity of up to 15 million gallons per day (mgd) from which it could draw as needed, once construction is complete, and provided infrastructure is in place to treat and pipe that water to Tigard.

City Councilor John Goodhouse characterized the city’s purchase of a share in the Willamette intake as a “down payment” of a little more than $3 million, which project consultant Dennis Koellermeier — Tigard’s former public works director — said is a substantially smaller investment than what was originally estimated. In other words, by buying in now, Tigard can give itself the option of drawing from the Willamette River in the future.

That option remains a theoretical one unless and until voters either repeal the 1999 charter amendment or vote to explicitly authorize the use of the Willamette River as a drinking water source.

“We still have a charter amendment that disallows the use of Willamette River water by the City of Tigard until we go back out for a vote to possibly change that,” said Mayor John L. Cook. “So that also would have to come at some point in the future.”

Jason Snider, the council president, suggested that necessity could make that an easy choice for voters.

“At some point, it may come to a question of whether we’re going to run out of water or if people are going to approve this,” Snider said.

About two-thirds of Tigard, along with neighboring Durham, King City and unincorporated Bull Mountain, currently receives its water from the Clackamas River, through a partnership project with Lake Oswego that just came online last summer. Tigard’s future plans include a further expansion of that partnership, increasing its current 14 mgd capacity up to 18 mgd.

Even factoring in a 6 mgd contingency source in the form of aquifer recovery and storage wells, though, Tigard officials have said they expect the city to struggle to meet demand within its water service area by the late 2060s, due to projected population growth.

Growth estimates are also what prompted Hillsboro and the Tualatin Valley Water District to embark upon the Willamette Water Supply Program, which carries an estimated total price tag of about $1 billion, one of the costliest infrastructure projects in Oregon history.

Construction work has already begun on the project. It is scheduled to begin supplying Willamette River water to Hillsboro and the Tualatin Valley Water District by 2026.

The Tualatin Valley Water District is the water provider for about one-third of Tigard, in the city’s north and east.

If the joint project comes online as expected, that would mean hundreds of thousands of Washington County residents will be drinking Willamette River water within a decade — joining water customers in Sherwood and Wilsonville who already do so. That could be significant, Koellermeier suggested.

“My view is that by that time, the world will have changed,” Koellermeier said of the point when Tigard may need to seek voter approval to tap the Willamette. “A good share of Washington County will now be using Willamette River water. There will be good experiences there.”

Some of those county residents will be Tigard residents as well. The Tualatin Valley Water District is the water provider for about one third of Tigard, in the city’s north and east.

The Tualatin Valley Water District is currently a wholesale customer of the Portland Water Bureau, along with a dozen other water districts and municipalities in the Portland area, including Tualatin.

Tigard bought water from Portland prior to the completion of the Lake Oswego-Tigard Water Partnership, at which point it switched over to the Clackamas River supply.

Boeckman Road Reopens Tuesday; One Week Ahead Of Schedule, Officials Say

The reopening of Boeckman Road marks another step forward for the Kinsman Road Extension Project, which is set to be complete summer 2018.

Hillsboro Water Department Celebrates National Infrastructure Week, Ongoing Pipeline Projects

The Willamette Water Supply Program is just one example of Hillsboro’s commitment to supporting water infrastructure.

By Travis Loose (Patch Staff) – May 16, 2017 1:48 pm ET

HILLSBORO, OR — Officials with the city’s Water Department on Monday announced the City of Hillsboro’s support and participation in national Infrastructure Week, which from May 15 to May 19 asks city governments across the country to advocate for local projects that support the roads, bridges, railways, energy systems, and utilities used by U.S. residents every day.

In Hillsboro, water utilities have been a priority for years, with past city leaders showing foresight by implementing plans decades ago that have not only benefitted Hillsboro residents today but also laid the groundwork for improvement projects that will support residents well into the future.

One example of Hillsboro’s penchant for forward thinking investments is the Willamette Water Supply Program (WWSP), a drinking water infrastructure project that has brought the Tualatin Valley Water District (TVWD) and City of Hillsboro together to construct a 30-mile, large diameter water pipeline from the mid-Willamette River at Wilsonville to North Hillsboro, near Bethany.

“This major water infrastructure project spans across five cities in Washington County, including Wilsonville, Tualatin, Sherwood, Beaverton, and Hillsboro,” Willamette Water Supply Program Director Dave Kraska said in a statement on April 25. “We have divided the work up into smaller pieces over several years. This allows and provides local and regional businesses of all sizes an opportunity to be a part of this historic project that will benefit the local economy, provide jobs, and support regional economic development.”

What are the five biggest things planned for 2017? We asked city officials

New water system, renewing the tax levy and South Hillsboro construction will all be on the city’s radar next year.


Hillsboro city officials are preparing for 2017, and a new slate of projects on the horizon will require more of a commitment than most New Year’s resolutions if they’re going to be launched next year.

As work continues on construction in South Hillsboro, city officials are setting their sights on several other projects in the next several months, according to city spokeswoman Corinne Weiss.

“Success to us means working together (with residents and area businesses),” Weiss said. “This coming year we have many great opportunities, and of course some challenges, but we will work to maintain excellent services and plan for a bright future for Hillsboro.”

One of the most important initiatives is convincing voters to renew the city’s longstanding local option tax, which is set to expire in 2018. The tax helps pay for police and fire department services and the city’s parks department.

If the city council follows through with city staff’s Dec. 6 recommendation, residents could vote on the tax renewal as early as May 2017.

In the city’s water department, a years-long plan to build a shared water system with Tualatin Valley Water will continue, as crews work to build the Willamette Water Supply Program pipeline, which will draw water from Wilsonville and pump it to Hillsboro.

Project officials anticipate construction at the intersection of Cornelius Pass Road and the Tualatin Valley Highway to begin in the early part of 2017.

A large portion of the 30-mile pipeline will pass through the South Hillsboro development as well, which will also see more construction throughout the year.

Colin Cooper, the city’s planning director, said 2017 will be about tying together community aspirations and the city’s plans.

“A significant focus (of the year) will be on improving mobility and a balance of housing options for community members,” Cooper said.

Some of that work will focus on the continued revitalization of downtown Hillsboro and the future of the former Hank’s Thriftway property, which the city acquired earlier this month. No plans have yet to be announced for the property, but the city is said to be looking at a mix of residential and commercial uses for the site.

The New Year will also mark a new chapter for community areas for leisure, play and relaxation.

“One of the best things about living or working in Hillsboro is our great quality of life, of course made even better by all our fantastic parks, trails and natural areas, fun recreational programs and a healthy and growing arts and culture scene,” said Parks & Recreation Director Dave Miletich. “In 2017, we will continue to offer great things, and new plans include opening the Orenco Woods Nature Park, developing a plan for the city-wide Crescent Park Greenway and creating a Community Cultural Arts Strategic Plan.”

While the Orenco Woods Nature Park will open in February, the Crescent Park Greenway is still in the planning stages.

Envisioned as a natural greenway loop, wrapping 16 miles around the city, Crescent Park will be a collection of natural areas, parks and trailheads connected by “linear greenspace,” Weiss said.

To help inform the plan’s details, city officials throughout the year will invite residents to community events to view content developed by city staff and note areas of interest.

“Proactive outreach and communication are essential to our ability to deliver great services to the community and to plan innovative, effective solutions to challenges we face as a growing community,” Weiss said.

Part of that outreach includes continuing to build on the city’s commitment to its youth, Weiss said.

“From providing School Resource Officers, to maintaining the sports fields at our high schools, to partnering on safe routes to schools, to helping support (Hillsboro School District) events and programs, such as the College and Career Pathways Program, the city remains committed to working together to give our students the best chance for success,” Weiss said, also noting the community events put on by the city, such as Celebrate Hillsboro, Pix on the Plaza, and OrenKoFest.

“In 2017, we will build on our efforts to engage with our diverse residents, partners, and businesses in creative ways, so that the Hillsboro community can continue to grow great things together.”

Pipeline work won’t disrupt traffic this year

An extension of Kinsman Road is under construction, with the pipeline planned for its right-of-way

The first pieces of the Willamette Water Supply Program (WWSP) pipeline have been laid in the Kinsman Road Extension project.

Created by the Tualatin Valley Water District (TVWD) and the City of Hillsboro, the WWSP is going to tap into the mid-Willamette River at Wilsonville to create additional water supply source for the TVWD and Hillsboro. Although the pipeline will run through Wilsonville, the City of Wilsonville won’t be paying for construction or using the water. The City is, however, partnering with WWSP and funding the $8.3 million Kinsman Road Extension. Negotiations with the WWDP about compensation for the use of the Wilsonville water treatment plant and for other inconveniences the City will undergo are ongoing.

Design for the WWSP started in January 2014 and has been in various phases of design with construction starting in 2016. Despite the City of Tualatin opting out in August and the City of Beaverton still deliberating if they want to be involved in the project, the first steps in the regional water system partnership to supply additional water to the area are underway.

Starting with its intake source at the Wilsonville water treatment plant in the mid-Willamette, the nearly 30-mile stretch of mostly 66-inch diameter water pipeline will have water storage tanks and water intake improvements to the existing water treatment plant.

The construction project began in July with work to extend Kinsman Road, combining existing infrastructure projects to help minimize congestion and reduce expenditures by not having multiple construction crews and management agencies, according to WWSP Media and Community Relations Coordinator Marlys Mock.

For the Kinsman project, a nearly half-mile extension of Kinsman Road, north of Barber Street to Boeckman Road, is set to improve north-south access, improve freight and residential mobility and add bike lanes, sidewalks and nature crossings.

While roadway infrastructure is being added, an upsized sanitary sewer pipe as well as a section of the WWSP water pipeline will be installed in the right-of-way. The estimated $8.3 million Kinsman project is being funded by the City of Wilsonville with partial federal aid assistance from the Federal Highway Administration, providing $3.6 through a combination of two federal grants.

“This cost includes design, property acquisition, permitting and construction for the roadway project,” Civil Engineer Zach Weigel said. “The project also includes upsizing and relocation of a sanitary sewer pipe at an additional total estimated cost of $1.4 million of which no federal grant money is included.”

One of the City’s WWSP project advisors, Mike Kohlhoff, said that the City is still in negotiations with the WWSP about compensation for the use of the water treatment plant and for other inconveniences the City will undergo. Kohlhoff said that they hope to reach an agreement by the end of the year but that there is no set timeline.

Whatever the negotiated figure comes out to be, according to Mock, the project is taking advantage of every cost-cutting measure available without sacrificing quality, including using Portland-based Northwest Pipe Company. By using the local company, the project is saving trucking costs while hauling the 66-inch pipes, benefitting the local economy.

Although the WWSP is priced in total at $1.2 billion, Wilsonville taxpayers shouldn’t be concerned about their taxes increasing.

“It’s not paid by taxes at all,” Mock said. “The project is funded by ratepayers in the TVWD and City of Hillsboro service district area and there’s going to be a bond spread out over time.”

City, water district officials celebrate pipe installation

The Willamette Water Supply Program saw its first bit of tangible progress this month, bringing one step closer the Willamette River-sourced secondary water supply for Hillsboro and the Tualatin Valley Water District service.

The primary source of water for Hillsboro is the Tualatin River, fed by the Hagg Lake and Barney reservoirs.

On Oct. 10, officials with the project, in coordination with engineers working on the Kinsman Road Extension in Wilsonville, installed the initial stretch of pipeline in the right-of-way as part of the city’s Kinsman Road construction project — a nearly half-mile long road extension with bike lanes and sidewalks north of Barber Street to Boeckman Road.

“This is a historic moment toward the completion of the Willamette Water Supply System,” said Program Director Dave Kraska. “Installing this first pipe is the beginning of following through on the vision and good planning taken by TVWD and the city of Hillsboro over the years. It is a big step forward in making this important regional reliable drinking water supply a reality.”

The Willamette Water Supply Program is a partnership between the city of Hillsboro and TVWD to bring water to ever-expanding Washington County.

Tualatin Valley Water District serves about 22,000 residents in Washington County from Hillsboro to Beaverton and Tigard. When finished, the project is expected to supply water to more than 300,000 residents and some of the state’s largest employers for the next 100 years.

The project will take a decade to complete, with several portions of the project to be installed as areas work on previously planned road construction.

According to project officials, the Kinsman Road construction represents one of many coordinated, combined construction partnership opportunities along the 30-mile water pipeline’s route, which will ultimately result in significant cost savings for water ratepayers by eliminating the need for multiple construction projects.

Marlys Mock, the project’s spokeswoman, said officials are constantly looking for ways to improve the pipe’s final route — while working with each of the projects’ engineers — in an effort to prevent costly projects from becoming even more so as a result of incorporating the pipe’s construction.

This was evident in a recent pipeline route alteration on Cornelius Pass Road in Hillsboro.

“The Cornelius Pass Road change eliminates the previous 205th/206th (Avenue) ‘bump out,’ which will decrease the route length and the number of stream crossings,” Mock told the Tribune.

“The revised route will also save construction time and project cost. Through careful evaluation of the proposed routing we are creating a more efficient, cost effective and less intrusive project.”

A second alteration, along the Tualatin-Sherwood route near Sherwood, was made to protect natural resources in the area, said Mock.

“The (new) route also takes advantage of possible opportunity projects — lessening traffic impacts along the busy Tualatin-Sherwood Road by combining efforts with Washington County,” Mock said, “which is (also) planning road improvements along the preferred pipe alignment.”

The next stick of pipe will be laid in conjunction with the 124th Avenue Extension Project — an interim two-lane road between Tualatin-Sherwood and Grahams Ferry roads. The project, which Mock anticipates will begin in November, will also construct safety improvements on Tonquin and Grahams Ferry roads.

Completion of the Kinsman project is projected for late 2017, and late 2018 for the 124th Avenue project.
