Kent Auburn Phase B construction update – summary of work as of October 2017 (see map of project below)

As of November 3, 2017 approximately 4.200 feet of pipeline have been installed. The contractor plans to continue work until rains and ground conditions cause them to stop for the winter.

Pacific – the contractor has finished the pipeline construction along Frontage Rd. They crossing Ellingson Rd. and expect to be done here in early November; this crossing is being done at night to reduce traffic impacts.

Algona – the contractor has been locating utilities (potholing) and installing the dewatering system (pumps, pipes, and generators) along Seattle Blvd. Pipeline construction along Seattle Blvd. should begin by mid-November. Work along the Interurban Trail corridor is expected to take place next spring.

Auburn – pipeline construction has been progressing, working south from Main St. West in Auburn. They are also currently working on pipe boring under SR-18, and under some railroad crossings. Work is expected to reach just north of 15th Street Southwest before stopping work for the winter. Work along Perimeter Rd. is expected to take place next spring.
