To improve fish passage through Coal Creek, the city is considering building a new bridge over the stream. Bellevue also may budget money this year to replace the aging sewer line that goes under Meydenbauer Bay.
These are just two of several projects the Bellevue Environmental Services Commission may recommend the City Council include in the Utilities Department's 2009-2015 capital investment program. Other possible additions to the water, sewer and storm and surface water CIP would expand reservoir capacity for downtown, wastewater capacity for the Wilburton area and drinking water supply for all of Bellevue west of Interstate 405.
The Commission will consider resident input, and an open house is set for 5 to 6:15 p.m., Thursday, at City Hall, in Conference Room 1E-112. A public comment session will follow at 6:30.
The budget for the current seven-year Utilities CIP is approximately $79 million. New projects being considered are listed below, with costs shown in 2008 dollars:
- Replace the Coal Creek culvert under Coal Creek Parkway south of the intersection with Forest Drive. The preferred replacement alternative is a 40-foot bridge, estimated to cost $5.5 million.
- Expand water reservoir storage volume to serve downtown Bellevue. The estimated cost, not including site acquisition (if needed), is estimated at $5 million and would be recovered from benefiting properties.
- Increase the wastewater system capacity for planned redevelopment within the Wilburton area. The estimated cost is estimated at $4.6 million and would be recovered from benefiting properties.
- Expand the inlet supply capacity and associated piping from the regional drinking water supply line to areas west of Interstate 405. This project will cost approximately $4 million.
- Increase the wastewater sewer trunkline capacity to allow planned development in the west portion of downtown Bellevue. Upgrades would occur from Bellevue Way Southeast and Southeast Third Street to 102nd Avenue Southeast and Southeast Sixth Street, with the optimal alignment to be determined. The cost of this project is approximately $3.3 million.
- Replace a portion of the sewer line in Meydenbauer Bay with a new line on city-owned property and an ongoing program to evaluate other sewer lakelines along the shores of Lake Washington and Lake Sammamish. The estimated seven-year cost is approximately $2.6 million.
- Relocate several water and wastewater pipes ahead of the state Department of Transportation’s State Route 520 expansion and I-405/SR 520 Braids projects. The estimated cost of the water projects is $1.5 million, and the estimated cost of the wastewater projects is $2.6 million.
- Add on-site generation to three sewer pump stations, to bring the total pump stations with on-site generators to 18 out of 38. The cost of this project is approximately $1 million.
- Replace Bellevue's analog-tone wastewater telemetry system with modern electronic technology. This will allow two-way communication and system operation rather than just monitoring. This project will cost approximately $350,000.
Utilities is also considering a change to one project in the current CIP:
- Accelerate the small-diameter water main replacement program over a 10-year period. The result would increase pipeline replacement from the current rate of 1.5 miles per year to five miles per year, focusing on asbestos cement pipe.
These proposals are under consideration only; there is no assurance they will be included in the final CIP recommended to the City Council. Staff and the ESC will consider citizen input before making CIP recommendations to the City Council later this year.

Citizen comments may be submitted in writing during or following the open house, or citizens are welcome to speak to the Environmental Services Commission immediately following the open house. Those who cannot attend the meeting can send e-mails to the Environmental Services Commission. The deadline for comments is 5 p.m., Monday, July 21. Letters can be sent to the Environmental Services Commission, c/o Utilities Department, P.O. Box 90012, Bellevue, WA 98009-9012.
After public hearings in the fall, a final list of projects will be adopted by the City Council before the end of the year.
