CWS will be starting to work on a variety of local issues
Several Clean Water Services projects will be going on in the King City area over the next few months that will reduce flooding and even improve the landscape.
Carrie Pak, CWS engineering division manager, made a presentation at the Citizen Participation Organization 4K (King City) meeting Jan. 27 about the projects, and Ryan Sandhu, CWS field operations division manager, provided additional information following the meeting.
The first project is a multi-agency one involving King City, Tigard, the Oregon Department of Transportation and CWS that will construct three water-quality swales within the median of Highway 99W along King City.
One swale will be located between Royalty Parkway and Durham Road; another swale will be located near the low spot north of Fisher Road; and the third swale will be sited between Fisher Road and Versailles.
The swales will total approximately 800 feet in length, according to Sandhu, who added, "The primary purpose of the project is to improve storm-water runoff by providing treatment of impervious-area runoff that is not currently treated."
Pak elaborated, explaining, "Clean Water Services was awarded a grant for the project. We will scrape it out and put in good soil and plants, which will provide drainage for almost 30 acres.
"We anticipate construction to start in May or June 2014, and we hope it will look nicer too."
The second project is improving a drainage problem at the intersection of Highway 99W and Beef Bend Road.
"This is a long-standing issue as drainage from Beef Bend/Tigard flows to open conveyance and an under-capacity 18-inch ODOT storm line," Pak said. "There is a possibility for multi-agencies - King City, Clean Water Services and ODOT - to address this issue along with the sidewalk project grant that King City has been granted (for a sidewalk along the west side of 99W from Beef Bend to Royalty Parkway).
"Additional details and options will be explored in the near future."
Sandhu added, "We are now patrolling that area. If a big rain storm is coming, we will check it in the morning and again in the afternoon to make sure the inlets are not blocked and are open.
"(King City City Manager) Dave Wells and I talked last fall about the city getting the sidewalk grant, and we're hoping we can maybe do the sidewalk and drainage projects together. It will be nice to get that area fixed for people."
A third issue is flooding at the intersection of King George and King Charles, where one garage especially floods during heavy rain along with a nearby cul de sac.
"About three years ago, we put in a newer catch-basin, which was a fairly economic solution," Sandhu said. "It has worked well except for a couple of large storms when the system gets overwhelmed."
Sandhu explained that the project fell under the CWS small works program, which has an annual budget of $50,000,
Pak added, "The proposed fix involves directing runoff to a nearby storm pipe with adequate capacity. The CWS Board of Directors has approved construction of this project during its meeting on Feb. 4, and work should be starting soon."
A fourth issue is street flooding on Queen Mary, with Pak noting, "We believe the flooding is associated with ODOT structure at 99W. We are exploring options with ODOT."
Sandhu added, "There's no better way (to prevent flooding) than for us to go out when it's raining hard and make sure inlets aren't blocked with debris and that the catch-basins stay open."
Finally, there is one more issue looming over (or under) the Garden Villas section of King City that CWS can't do anything about.
A private system of six-inch sanitary sewer lines runs under many homes and yards, while the minimum standard calls for lines eight inches in diameter.
"I went and talked to their homeowners' association in 2010 about the situation," Sandhu said. "Instead of constructing the lines in the right-of-way, they go under homes and yards and through lots - it's not the usual way. We've had folks call about back-up problems, and they talk to our crews when they are out there.
"The fix would be for the folks to get together and form a local improvement district to lay new lines in a more accessible area.
These are the homes along Matador, Monterey, Riviera, 129th and so on - it's a large number of residents affected, but we can't expend funds to replace the system."
When asked about the Garden Villa situation, King City Civic Association Administrator J. Patrick Moore said that the logical place to lay new lines is the alleyways between the back yards of the homes, which are meant for the placement of utilities.
Pak noted at the CPO meeting, "It is not built to city standards. We can provide the expertise, but we can't spend public money on it."
