The average percentage is about 15% and the average daily cost is about $2,500 per day.

Metro King County 2005 Sewer Rate Increase Metro is increasing its 2005 sewer charges for service and for new connections. They have been charging for new connections since 1990, ' and those rates will go up again next year. Generally people pay the'cost up front or over 15 years. There will be a 9% increase in monthly sewer rates, resulting in an average charge of $32.60 per single-family house in 2005. The connection fee is increasing from $18 per month to $34.05. Pam C noted it is City policy to pass on increases from Metro. Recommend ordinance to COW and Regular Meetings. 2. 2004 Small Drainage Bid Award Dennis Craig, Inc. won the contract for the small drainage projects for this year. There are seven projects, including the S. 180th Street underpass drainage repair. There was not a map of where the other six projects were, and staff promised there would be a map when it went to Council. Dennis asked for a rough cost of each of the projects. Funding for the projects will come from the street fund, although staff is working to get the S. 180th project funded separately. The lowest puce was higher than the engineer's estimate. Recommend bid award to COW and Council for approval. 3. Fort Dent Storm water Pump Station #19 The City tried to repair Pump Station 19, but it was too far gone to be repaired. Replacement of the pump station was needed, and some associated drainage improvements were added. Drainage from the parking lot that now goes to the river will be diverted to the pond, and will be cleaned a little more than currently. The winning bid from Western Engineering Constructors, Inc. for $221,588.17 was quite a bit lower than the engineer's estimate. Recommend bid award to COW and Regular Meeting for approval. 4. Fort Dent .Storm water Construction Services_ Penhallegon Associates Consulting Engineers, Inc. (PACE) won the contract to design the improvements needed at Fort Dent drainage. Staff would normally do this, but they are too busy to be able to do that just now. The $50,078 contract will cover about 65 working days in a 90-day period. Dennis thought it was expensive, but he realized staff couldn't afford to do it. Recommend bid award to COW and Regular Meeting for approval. 5. Information Notices Committee members appreciated seeing what the citizens will see in the Hazelnut. They changed the open house in Allentown from 7-9 to 6-8 October 6th. Information. 6. Other Pam C raised the issue of dead plantings on S. 51st near Bonsai. Staff said they thought it was past the time the contractor had to keep them alive, but said they would check. Information.
