BACKGROUND In 2020, the engineer's estimate for widening 53rd Avenue S between S 137th Street and 52nd Avenue S for two-way traffic and adding sidewalks was $222,250, plus construction management costs. A barrier to this project was a guy pole that needed to be relocated by Seattle City Light (SCL) before widening for two-way traffic could commence. Due to these factors, this project was identified as cost prohibitive, and as an alternative, the decision was made to convert the roadway to a one-way northbound operation, while a new at -grade pedestrian walkway was installed. All construction was completed by City staff to reduce costs. During the April 12, 2021 Transportation and Infrastructure Services Committee meeting, staff presented three options for Council consideration to improve pedestrian safety and vehicular access on this section of roadway. The Committee members were supportive of Option A, which included installation of raised sidewalks on the east side of the road, design for two-way traffic, and construction as soon as funding became available. DISCUSSION One June 17, 2021, negotiation with SCL came to a resolution and they are expected to remove their guy pole by July 12, 2021, allowing this project to move forward quickly. Due to this new development, the 53rd Ave S roadway widening plans were presented to Miles Resources, LCC, the construction contractor awarded the 2021 Overlay and Repair Program contract by Council on June 7, 2021, in the amount of $1,037,358.40 plus $51,867.92 in contingency. Using existing contract prices, Miles Resources, LLC estimates the road widening could be completed for approximately $50,000. Staff discussed the tremendous cost savings with Administration and the decision to move forward with the additional work was made on June 21, 2021, based on the Committee support from the April 12, 2021 meeting. FINANCIAL IMPACT Widening of 53rd Avenue S is anticipated to add approximately $50,000 to the Miles Resources, LLC contact, after adding the additional work and subtracting known project under -runs. The current estimate falls within the contract contingency of $51,867.92. Contract Budget Miles Resources, LLC Contract $1,037,358.40 Additional Work for 53rd Ave S 50,000.00 Total $1,087,358.40 RECOMMENDATION Discussion only.

BACKGROUND In 2020, the City desired to improve pedestrian safety on the 53rd Ave S between S 137th St and 52nd Ave S. The existing roadway was not wide enough to safely accommodate two-way traffic and pedestrians. With limited funding, the City Street division was utilized to install a new at -grade pedestrian walkway on 53rd Ave S and revise the traffic direction to one-way northbound. At the same time, 52nd PI S was changed to one-way southbound. While pedestrian safety was greatly improved, the one-way street revision created substantial concerns with some residents. Staff was requested to look at options for improvement and report back to the Transportation & Infrastructure Services Committee. ANALYSIS Staff, along with consultant support from KPG, have been considering multiple options to improve the current conditions. With the funding restored to the 2021 Overlay Program, a raised sidewalk along 53rd Ave S and S 137th St is scheduled to be constructed in the Summer of 2021. Per the current design, the traffic on 52nd PI S would be returned to one-way northbound operation per the community's request. Ultimately, the best solution would be to resume two-way traffic on 53rd Ave S. KPG is working on a low-cost solution for restoring two-way traffic in conjunction with the sidewalks, which would widen the roadway to the west. The need to coordinate with Seattle City Light for a pole relocation will likely prevent the work from being included this summer and will be dependent upon funding availability. Additional options for discussion: 1. Option A: Add the sidewalks, keep 53rd Ave S as one-way northbound, return operation on 52nd PI S to northbound and construct in Summer 2021. Design the 53rd Ave S widening for two-way traffic and construct as soon as funding is secured. Cost estimate is under development. 2. Option B: Add the sidewalks, keep 53rd Ave S as one-way northbound, return operation on 52nd PI S to northbound and construct in summer 2021. No widening pursued. 3. Option C: Add the sidewalks, revise 53rd Ave S as one-way southbound, revert the direction on 52nd PI S to northbound and construct in summer 2021. This option will cost more than #2 due to relocating the current signs. Additional traffic issues may appear despite traffic control efforts. FISCAL IMPACT Cost estimates still being developed. RECOMMENDATION Staff was requested to present this item for discussion to update the Council about the 53rd Ave S sidewalk project progress. With recent and continued comments from the area residents, we now recommend pursuing option A, which will provide the best solution for the community.
