244th AVENUE WATERMAIN EXTENSION

 

See Capital Improvement Projects Figure

 

PROJECT UPDATE (January 30, 2008)

 

The City of Sammamish is proposing to construct a road extension on 244th Avenue NE from NE 3rd to NE 8th Street, and to make other road improvements between SE 8th Street and NE 3rd Street. A portion of the road extension will include a bridge across the wetlands just west of Allen Lake.

 

As part of this road improvement project, the District plans to complete a 12" watermain extension to link NE 8th Street and Main Street in the District's 550 pressure zone. This will provide redundancy and better flow from the Section 36 Tanks to the District's distribution system. The design will also include the relocation of District facilities that pose conflicts with the City's proposed road improvements between SE 8th Street and NE 3rd Street, and at NE 8th and 244th Avenue NE.

 

In March 2007, the District hired HDR Engineering Inc. to prepare the design of the 244th Avenue Watermain Extension Project, SE 8th to NE 8th Project. The project includes 2,000 feet of watermain from NE 3rd Way northward to NE 8th Street. Due to the proposed road revisions, the depth of cover over the District facilities will force the District to relocate the existing watermains (8", 12", and 18" DI) and existing sewer forcemains (10" DI) within 244th Avenue NE and NE 8th intersection. The project also includes the installation of watermain and a casing for the sewer forcemain on the City's proposed bridge j ust north of NE 3rd Way and west of Allen Lake.
