Also, King County will hold a community meeting on Wednesday, April 30, to discuss project details and get public comment on landscape and facility design, such as site layout, aesthetics and appearance of aboveground facilities. The meeting is scheduled to run from 6-8:30 p.m. at the Richmond Beach Congregational Church, 1512 N.W. 195th St. King County protects public health and water quality by conveying and treating the region's wastewater. The pump station serves part of Shoreline and collects sewage from the Ronald Wastewater District and Highlands Sewer District. Project engineers have determined that King County must replace the aging pump station and part of the Boeing Creek trunk sewer. King County also needs to build an underground wastewater storage pipe to help limit overflows to nearby Puget Sound. Construction is tentatively scheduled to run from 2004-2006. What to expect during testing Beginning the week of March 31, the contractor will use a drilling truck to gather soil and groundwater data. The work will take about eight weeks, and no weekend work is planned. Work will take place according to City of Shoreline standards along selected street right-of-ways from King County's Richmond Beach Pump Station at Northeast 198th Street and Richmond Beach Drive south to about 10th Avenue Northwest and Innis Arden Way. King County will get the permission of property owners if it needs to conduct tests outside the public right-of-way. Nearby residents and property owners will receive a map and other information about the project. The drilling truck will operate from 8 a.m. to 5 p.m. weekdays. The work crew will spend about half a day at each location. During work hours, nearby residents and park users may hear some equipment noise. When the crew finishes its work, workers will cover each test hole. The crew will clean the site and haul away all excavated material. Project needs and plans The Hidden Lake Pump Station sends sewage north through the Boeing Creek trunk sewer to the Richmond Beach Pump Station and on to the City of Edmonds' wastewater treatment plant. King County has an agreement with Edmonds in which the city treats some county flows in exchange for the county treating some city flows. The Hidden Lake station, located at the corner of 10th Avenue Northwest and Northwest Innis Arden Way, is nearly 40 years old. It is under capacity and does not meet current King County pump station design standards, including odor and noise control standards. The station now overflows into Puget Sound about three times a year. With increased pumping capacity and pipeline storage, the station could handle what's called a five-year storm. A five-year storm has a statistical chance of happening an average of once in five years. Sections of the Boeing Creek sewer are also in poor condition and under capacity. King County restored the sewer's condition in the early 1990s by relining some corroded sections. But the relining reduced capacity. King County plans to replace about 12,000 feet of the sewer along the existing route and improve odor control in problem areas. Also to limit overflows to Puget Sound during peak storms, King County is planning to build a 500,000-gallon underground storage pipe. The pipe would store wastewater temporarily during peak storms.

A contractor for King County's Wastewater Treatment Division will be conducting soil and groundwater investigations this April and May in west Shoreline. King County will use the information in designing its Hidden Lake Pump Station, a storage pipe and nearby sewers.
