Unexpected work increases cost of 212th and 76th intersection project, City Council committee learns

    Changes to a replacement sewer line plus increased costs to convert overhead power and facilities to an underground system means that the City of Edmonds will pay more than budgeted for 212th Street Southwest and 76th Avenue West intersection improvement project.

    That was the report that Public Works Director Phil Williams and City Engineer Rob English gave to the Edmonds City Council’s Parks, Planning and Public Works Committee Tuesday night.

    The good news is, the city has the funding — from federal and state grant dollars as well as the city’s sewer, water and stormwater funds — to cover the increased costs, estimated at $171,922, although that amount could change after figures are reviewed and finalized, English said.

    The full council will hear a report on the project during its business meeting next week, as the council is being asked to authorize Mayor Dave Earling to approve a budget change order.

    The city had estimated in November that it would need an additional $425,000– plus a $300,000 overall increase to the management reserve — to cover expenses associated with digging a deeper-than-expected replacement sewer line as part of the intersection project.

    English explained that the sewer line estimate was based on the city’s records, plus information received verbally from the contractor. However, on Dec. 21, the contractor submitted written invoices that were $109,530 more than the city’s estimate in November. The final amount paid to the contractor may be less, since staff is in the process of verifying the documents submitted, English added.

    In addition, Snohomish County PUD submitted an invoice for $206,855 for its work to move overhead power lines at the intersection underground, which was $28,355 more than the utility’s original estimate. The additional amount covers extra work by PUD to install a temporary power service to maintain power to Dairy Queen during the underground conversion. The utility also had to install a temporary service to maintain power to the traffic signal controller at the intersection’s southwest corner.

    Frontier Communications also anticipates a 25 percent increase over its original budget for work to relocate overhead facilities. English said he hasn’t yet received an invoice from Frontier — or specific reasons for that increase — but attributed it to how complicated the project was overall.

    Staff is recommending that the contract be increased by $109,530 for the unforeseen sewer main replacement work. This cost will be paid by sewer utility funds with smaller contributions by the city’s water utility fund and grant dollars. In addition, the recommendation calls for a management reserve increase of $165,185 to pay for the additional sewer line work, plus $28,355 for PUD work and $27,300 for Frontier.

    The goal of the 212th/76th project is to enhance traffic flow by increasing the capacity of the intersection while decreasing delays. This includes adding dedicated left- and right-turn lanes on 76th Avenue, and new traffic signaling that will allow simultaneous flow of traffic north and south. In addition to moving utilities underground, the project included replacement of sewer and water pipe as well as a new stormwater detention basin.

    The intersection project was one of several public works projects discussed during Tuesday night’s committee meeting. The committee (consisting of Councilmembers Neil Tibbott and Kristiana Johnson) agreed to refer the following items to next week’s consent agenda for approval:

    – A public access easement for a private home being built on the northeast corner of 755 Bell Street.

    – A supplemental agreement with Stantec Consulting Services, Inc. to provide on-call staffing to fill in for a public works employee returning to work part-time after being on maternity leave.

    – Extension of an interlocal agreement with the cities of Mountlake Terrace and Lake Forest Park to support the Lake Balllinger/McAleer Creek Watershed Forum, which is working to address water quality and flooding issues related to Lake Ballinger. Under the agreement, which runs through Dec. 31, 2020, Edmonds will annually provide $1,600 toward administrative expenses and up to $12,000 to fund a federal lobbyist.

    – A supplemental agreement with OTAK to provide consultant support as the city seeks new bids for the 238th Street Southwest Walkway Project. (Earlier bids received in 2017 were rejected because they exceeded the project budget, and the city plans to rebid the project this year.)

    The committee also agreed to bring before the full council next week a staff recommendation regarding funding for the Dayton Street Pump Station project, which is aimed at addressing ongoing flooding at Dayton Street. The city is seeking a $500,000 FEMA Hazard Mitigation Grant for the project, but awarding of those grants has been delayed due to natural disasters that FEMA has been addressing in recent months, English said. While the city is waiting to hear back on that grant, staff is asking the council to approve a low-interest, $545,000 loan through Snohomish County. The estimated loan would be in addition to the federal grant, as the total preliminary estimated cost for the Dayton Street project is $1.45 million.

    Finally, the committee heard from Public Works Director Phil Williams that the long-awaited lighting has been installed at Pine Street next to Highway 104, and the city has received several positive emails in response to the project.

    In addition, during a brief business meeting prior to the committee meetings, the entire council approved a resolution to ratify the council president and president pro tem election that took place on Dec. 5, 2017. The resolution corrects the original ordinance, which mistakenly had an effective date of Dec. 15, 2017.

    1. Indeed it has become a much broader intersection, which raises a simple question. Will there be
      time enough for the students to run across the street without fear of being hit?? Before this change
      over, it was at times difficult for students to get across the street, and now it is made all the more
      difficult and dangerous. Time will tell….


    2. Surely, for any project, the City of Edmonds staff expect an increase in cost of at least 10% over on any job?
      I know that is applicable on any home job repairs I need. This type of over run happens often: the 5 ways corner roundabout was approximately $66,000.00 over cost, the park repair buffer off 76th west was about 1 million extra and a City lawsuit under Mayor Cooper. And the costs go on……
