From ODOT:

A nearly 70 year old drainage system of ditches and pipes, needed to collect and convey surface and groundwater, has failed near Hwy 101 and Beverly Drive. The drainage system also handled run-off from a pond south of the junction of NE Beverly Drive and NE 121st Street. Over the past few years, ditches have been filled and drainage pipes have collapsed, allowing storm water and pond discharge to travel over the ground surface, where it emptied into a storm drain at the edge of US 101. That water, along with sediment gathered during the drainage, overwhelms the storm drain and threatens to erode US 101.

In order to design a new drainage system, we need to inspect the existing system completely. Therefore we need to drain most of the water from the pond. We will begin that process shortly by pumping the water through a network of hoses, ditches and flex pipe, located on ODOT and Lincoln County right of way. The draining water will go into a catch basin which feeds a tributary of Spencer Creek at US 101 and NE 121St Street.

Pumping the pond will also allow us to safely convey the water in a manner that eliminates the threat of erosion to US 101. We will begin pumping the pond in October and continue through the winter ahead. Once the water level of the pond is reduced, we can begin analyzing the current failed drainage system and start designing a one. It would be built no sooner than 2016. It will be necessary to continue pumping the pond, for reasons of geotechnical stability, until a new system is in place.

ODOT is collaborating with Lincoln County and the Beverly Beach Water District, which has jurisdiction over the pond. We understand and agree with the District’s desire to keep a suitable amount of water in the pond to serve as a back-up source of water for firefighting. The project will have little direct impact to travel on US 101. Most of the work will take place east of the highway.

We will offer updates during the winter as we continue to pump. And if you have any questions, please don’t hesitate to contact ODOT.

In an effort to widen our communication outreach, please share this information with anyone who would benefit from it.
