Scoggins Dam safety teeters on politics
Washington County officials are hopeful that funds will come
The tide appears to be turning for Scoggins Dam, an earthquake-vulnerable structure that contains the Henry Hagg Lake reservoir near Forest Grove.
The 151-foot-high earthen dam, built in 1975 and long in need of seismic repairs and added capacity, has been mired for years in a political and bureaucratic morass stretching from Washington County to Washington, D.C.
But hopes for a bigger, safer dam have been rising this year, as support for the project picked up. The repair projects key elements are now attached to an appropriations bill queued up for a vote in Congress before years end.
Weve gotten more traction on this project in the last 18 months than we have in the last five years, says Mark Jockers, government and public affairs manager for Clean Water Services.
The path to change:
Jan. 16: Oregon Sens. Ron Wyden and Jeff Merkley introduce a bill to the Senate that allows for critical upgrades to federally owned dams, including Scoggins. The bill was co-sponsored by Sens. Dianne Feinstein, D-Calif., and Brian Schatz, D-Hawaii.
Jan. 25: Wyden leaves the helm of the Energy and Natural Resources Committee to join the powerful Senate Finance Committee as chairman.
Feb. 27: Washington County Chairman Andy Duyck flew to Washington, D.C., to testify before a Senate subcommittee on energy and natural resources. He spoke in favor of the Wyden-Merkley bill and stressed the importance of Scoggins Dam to the region.
June 18: The Senate Energy and Natural Resources Committee passed S. 1946.
July 31: The Senate Energy and Water Appropriations Committee took another tack, adding statutory language to raise the funding cap for vulnerable dams; reauthorize the Safety of Dams Act; and provide reclamations with the authority to perform seismic repairs at the same time as adding capacity.
It was a win-win, says Jockers of the long-awaited magic words. It more than accomplished the goal of the legislation and responds directly to the call Chair Duyck made in his testimony.
Getting permission for the Bureau of Reclamations to do both jobs at once had been a hard-fought battle for the dams future. A 2012 estimate placed the seismic upgrades alone at $340 million. Its not yet known how much adding 14 feet to the dams height will cost, but its cheaper to do both at once, Jockers says.
Water use growing
While seismic fears grab the headlines, the need for increased water capacity at the dam is real and its critical. Washington County has the highest population growth rate of any county in Oregon, 1.5 percent annually, with a 2013 head count of 554,996, according to U.S. Census data.
Scoggins Dam spans a tributary of the Tualatin River, storing water for farm irrigation, municipal and industrial use. In addition to residential needs, businesses have grown, in some cases astronomically. Intel Corp. arrived in Oregon in 1974, drawn in part by an abundant water supply.
We came for reliable water, electricity and because the local government really wanted us to come here, says Jill Eiland, corporate affairs director for Intel in Oregon, Washington and Colorado.
Intel is the states largest for-profit employer, with 17,500 employees. On Aug. 26, Intel indicated it would stay quite awhile longer, striking a deal with Washington County and the city of Hillsboro to receive a 30-year tax break on the companys local investments of up to $100 billion.
Its been five years since the August 2009 Safety of Dams study by the U.S. Bureau of Reclamation revealed Scoggins Dam was at high risk of damage in the event of a 9.0-or-higher earthquake.
According the National Performance of Dams Program at Stanford University:
Oregon Building Codes werent updated until 1994 to take earthquakes into account, nearly 20 years after the dam was built.
Flooding from the 53,000-acre-feet of water behind the dam would affect more than 4,445 people along the Tualatin River Basin, from Forest Grove to Lake Oswego and West Linn.
The Stimson Lumber Mill is less than a mile southeast of the dam. In the event of a 9.0-or-higher earthquake, the mill would be hit within 15 minutes with 17,000 tons of water reaching a maximum height of 25 feet.
Scoggins Dams seismic deficiencies qualify it for funding from the Bureau of Reclamations Safety of Dams Act. Federal funds should cover 85 percent of the cost, with the remaining 15 percent split among local stakeholders with water stored behind the dam: Tualatin Valley Irrigation District (farmland), Clean Water Services and the cities of Beaverton, Hillsboro and Forest Grove.
But there hasnt been enough federal money to fund the huge backlog of dam safety work thats needed, according to February testimony from Bob Quint, senior adviser to the Bureau of Reclamation. In Reclamations inventory of 476 dams, 370 are classified as high hazard dams and dikes, he said. Just 11 dams would fit under the bureaus spending cap for 2014. Six additional dams, including planned work at B.F. Sisk Dam in California and Scoggins Dam in Oregon, are in need of risk-reduction action, with combined costs estimated at $1 billion.
Though theres some risk that Scoggins will get thrown overboard as the appropriations bill motors closer to a vote, experts dont think so.
An appropriations bill has to be passed or the government stops working. Its more likely to pass this time, says Jockers. Weve been working with both the Senate and House Committee staff on this and, although their report language varies slightly, all indications are that both committees are supportive.
Doing nothing is not an option. We have to address this and make it safer, sooner, and with more water capacity.JW_DISQUS_ADD_A_COMMENT
