City of Tukwila Allan Ekberg, Mayor INFORMATIONAL MEMORANDUM TO: Transportation and Infrastructure Committ FROM: Bob Giberson, Public Works Director BY: Ryan Larson, Senior Program Manager CC: Mayor Ekberg DATE: September 22, 2017 SUBJECT: 53rd Ave South (S 137th St — S 144th St) Project No. 99110301 Project Update ISSUE Provide the Transportation and Infrastructure Committee an update on the 53rd Ave S Project. BACKGROUND The 53rd Ave S Project will include constructing roadway, drainage, sidewalks, illumination, water and sewer upgrades, and undergrounding of overhead utilities between S 137th St and S 144th St. City Residential Street, Water, Sewer, and Surface Water funds were used to fund the design effort. Transportation Improvement Board (TIB) Funding of $2,141,400 was obtained to fund a portion of the construction and right-of-way with the remaining funding from Seattle City Light, and City bond funds. DISCUSSION The project is currently being designed by KPG and is at the 90% design level. Remaining design work includes completing negotiations with property owners for right-of-way, working with third party utilities on undergrounding and utility relocations, and incorporating final changes into the Plans, Specifications, and Estimate. A contract design supplement will be necessary for added design work relating to utility relocation and adding an irrigation system for the street medians. Right-of-way is needed at various locations to allow the placement of utilities, retaining walls, sidewalks and storm water treatment. To date, all but two of the 15 property owners have agreed to the City's terms. The two remaining properties include a private resident and the Tukwila School District, which owns four parcels that make up the majority of Foster Park. Negotiations will continue with these two property owners but condemnation may be necessary if negotiations fail. The tentative schedule is to complete the design work in November 2017, advertise for construction in December 2017, and open bids in January 2018. Construction is anticipated to begin in February 2018 and be completed by early 2019. During construction, the road will be closed to through traffic, but will remain open to residents only. A signed detour route will be provided. The preliminary cost estimate for construction at 90% design is $7,500,000. Currently there is only $6,060,000 budgeted with the 103 Residential Street Fund having a $1,228,000 shortfall. The 53rd Ave S Project does have Transportation Improvement Board funding and they may be able to assist with additional funding. While bid results have been higher overall in the region, November is a good month to advertise for construction bids. RECOMMENDATION Information only.
