Envision

King County works to build and operate facilities that benefit the local community, environment, and economy on all our projects. The good news is King County can now earn a certificate for these efforts. The Envision program provides a framework to help measure how well an organization incorporates sustainability on infrastructure projects.

Envision is similar to LEED.

King County owns and operates the Sunset and Heathfield pump stations in Bellevue. The pump stations and sewer force main pipe send sewage from Sammamish, Issaquah, and Bellevue to be cleaned at the county’s wastewater treatment plant in Renton. This project will upgrade the pump stations and the connected sewer force main pipe with additional capacity to serve the area’s growing population. The project will also upgrade the underground connection structure to Eastgate Trunk near I-90.

The pump stations and connected force main pipe have served the area for 50 years. They need to be upgraded to keep up with the growing population. This project will ensure King County can provide continued reliable sewer service to the growing area for years to come.

Four new pumps, new electrical and controls systems, new standby generators, and new heating and air conditioning systems will be installed at each pump station. Current designs include new rain gardens at each pump station and a new green roof at the Sunset Pump Station. The connecting force main pipe will be replaced with a larger one. The roof on each pump station will be replaced. The current building footprints are not expected to change.

The project team has finished the preliminary design phase. At this point, the project team knows the general layout and type of pump station equipment that will be used. The general route of the force main pipe and construction methods have also been determined. The team will complete the final design by the end of 2016. Construction is expected to begin in 2017 and end in 2020.

Reliability, efficiency, lifecycle cost, permitting, operations and maintenance needs, environmental impacts, community input, and sustainability are some of the factors the project team considers.

Yes! On March 3, 2015, King County will host an open house at Vasa Park Ballroom. The County is asking for input on the new fencing and lighting Sunset Pump Station. Individuals may also provide feedback through an online open house at http://sunsetheathfield.publicmeeting.info/ 

More than 250 neighbors and community members were surveyed so the project team could learn about the community’s interests and concerns. Based on their answers, King County knows neighbors want to maintain the look and feel of the project area and reduce traffic impacts during construction.

Noise is expected to remain at current levels, and will continue to comply with the City of Bellevue noise ordinance requirements. The team has already tested baseline level noise and is awaiting noise study results.

Most construction activity near Vasa Park is expected to occur between November and March. Access to and from Vasa Park will be maintained at all times. King County will work closely with Vasa Park throughout construction to minimize impacts to the park.

The new force main pipe will be installed along Southeast 35th Place, 164th Place Southeast, and Southeast 38th Street force main pipe construction is anticipated to begin in 2017 and two different construction methods will be used. You can expect to experience road closures, noise, traffic control, and detours. You will see signs, crew members, trucks, and equipment on site. King County will work with the community to reduce construction impacts when possible.

Most of the work will occur inside each pump station. Improvements outside of the building include new landscaping and a larger generator. You will see crew members, trucks, and equipment on site. King County will work with the community to reduce construction impacts when possible.

The project team will continue to collect and review information on animals, plants, creeks, and wetlands in the area. King County will work with the community, City of Bellevue, and appropriate government agencies to make sure all environmental restoration activities meet the neighborhood’s needs and legal requirements. Low-impact construction methods will be used where the new force main pipe crosses Vasa Creek. Trees and other plants may need to be removed during construction. The county will re-plant new trees and plants in their place at the end of the project when possible.

No permanent artwork is expected at either pump station. Project and King County wastewater information may be installed at a kiosk along the I-90 trail system between West Lake Sammamish Parkway Southeast and Southeast Eastgate Way. This signage would help educate community members about the project. The community would be able to share input on the design.

Our team is planning to partner with local schools to educate students about wastewater. The county is happy to set up a site tour for classes that want to learn about their sewer service. For more information, contact De’Sean Quinn at
 desean.quinn@kingcounty.gov or  206-477-5417.

The project team will continue designing elements of the project through 2016. Most of their work won’t be visible day to day. Although, you may see crews in the area collecting data or completing field investigations. King County will continue to work with the community and notify them before construction begins.
