AB - 3800 City Council Regular Meeting - 14 Apr 2025 SUBJECT/TITLE: Amendment 1 to CAG-24-023 with WSP USA Inc. for the Lind Ave SW Storm System Improvement Project RECOMMENDED ACTION: Refer to Utilities Committee DEPARTMENT: Public Works Utility Systems Division STAFF CONTACT: Troy Solly, Surface Water Civil Engineer III EXT.: 7313 FISCAL IMPACT SUMMARY: Amendment No. 1 to CAG-24-023 with WSP USA Inc. increases the total amount of this agreement by $349,657, from $549,954 to $899,611. Services provided under this amendment are associated with the design of water quality treatment facilities. This work is funded by a Water Quality grant from the Department of Ecology (CAG-24-261) in the amount of $297,500 approved by Council on December 9, 2024. Additionally, the proposed 2025 Carry Forward/Q1 Adjusted Surface Water Utility Capital Improvement Program budget for this project (427.475523.015.594.31.63.000) is $1,161,463.31, includes sufficient funding to cover the city’s matching requirement. SUMMARY OF ACTION: The Lind Ave SW Storm System Improvement project was initiated to reduce flood risk along SW 43rd Streetby designing and constructing a new 48-inch trunk line storm system along Lind Ave SW and SW 39th St that would discharge to Springbrook Creek. Under existing conditions, untreated stormwater runoff from Lind Ave SW and SW 39th St is discharged directly into Springbrook Creek. At the discharge point for this project, Springbrook Creek is categorized by the Washington State Department of Ecology to be impaired across multiple water quality indicators. The Lind Ave SW Storm System Improvement project provides an opportunity to add runoff treatment retrofits to reduce pollutant discharge to Springbrook Creek. PW/Surface Water Engineering secured a grant (CAG-24-261) from the Department of Ecology thatfully covers the design of water quality treatment facilities. With this grant, the scope of this project expanded from a drainage improvement project to a multi-benefit project that would providetreatment for stormwater runoff along Lind Ave SW from SW 43rd St to SW 39th St and along SW 39th St from Lind Ave SW to Springbrook Creek. Treatment facilities installed along the project corridor would discharge to the proposed 48-inch pipe.The treated area consists of approximately 6 acres, with roughly 4 acres of pollution generating impervious surface. The drainage subbasin is zoned as mixed commercial arterial, commercial office, industrial light, and industrial medium. Roads within the project area have sidewalks, planter strips, and curb and gutter, but have no stormwater runoff treatment facilities. The existing agreement with WSP USA, Inc. covers the design of the conveyance improvements up to30%.This amendmentadds engineering services associated with the design ofwater quality treatment facilities covered by the Ecology grant. These servicesinclude preliminary (30%) design to identify the types, sizes, and locations of the stormwater quality retrofits, 60% and 100% design, as well as datacollection, reporting, and modeling work required to deliver these submittals. The design of water quality treatment facilities on this project will be evolved in tandem with the drainage improvements design. A future amendment associated with the AGENDA ITEM #1. a) engineering services required for final design of the drainage improvements is anticipated in the fourth quarter of 2025. The addition of the water quality treatment design work will not impact the overall project schedule for construction, which is planned to start in 2027. EXHIBITS: A. Site Map B.

The limits of the stormwater quality retrofit potion of the project coincide with proposed stormwater conveyance improvements. The engineering design work includes preliminary design (approximately 30%) to identify the types, sizes, and locations of the stormwater quality retrofits as well as any other data necessary for final design and plans preparation. A Draft Design Report for the stormwater quality retrofits will coincide with the submittal of the conveyance project Final Design Memorandum completed as part of the stormwater conveyance portion of the project. Additional stormwater quality submittals, including 60% through 100% design, will generally coincide with the stormwater conveyance project submittals . The following tasks beginning at Task 50 (Task no. 50 was selected to allow for future task to be added sequentially to the existing conveyance contract) will be added to the contract for the design of stormwater quality retrofits. Where task match up with the Ecology Grant Agreement, the grant agreement task number is included as reference. Task 50 – WQ Retrofit Administration, Meetings, and Quality Assurance The City of Renton (City) received a water quality retrofit grant from the Washington State Department of Ecology (Ecology) to provide enhanced treatment along the project corridor. This task includes setting up a work plan, preparing an amendment with the City for this supplement work, tracking the work under this task separately in terms of costs and efforts (as subtasks within the original contract). This task includes: • Monthly progress reporting on WQ Retrofit activities and costs. Costs will be tracked and summarized separately from the Conveyance project. These costs will be tracked as part of ECY Task 3. • Miscellaneous coordination with the City using email and telephone conversations. Most coordination is assumed to be completed by monthly 30-minute status calls. • Development of Work Plan for project including scope, budget, assignments, and deliverables. • Updating a project schedule to reflect the WQ Retrofit integrated with the Conveyance project. • Quality assurance and tracking of quality control of project deliverables. Task 50 - Assumptions • The project duration is anticipated to be from approximately December 2024 through June 2026. If the project schedule is extended, it could result in additional project management effort. • All coordination with Ecology will be through the City (applies to all tasks). Task 50 - Deliverables AGENDA ITEM #1. a) • Project correspondence as needed. • Monthly Progress Reports. • Up to twenty 30 minute monthly status calls Task 51 – SEPA Checklist (ECY Task 2.3 and 2.4) Consultant will prepare a Draft and Final SEPA checklist using the standard form from the Department of Ecology.

This alignment is preliminary and may be subject to change. This task will include the development of a Water Quality Retrofit Design Report for review by the City and Ecology. The report will include the following elements: - Review and identify potential locations for treatment BMPs and assess their feasibility (e.g., BMPs to be likely located around existing inlets and will need to consider available space (within ROW), sidewalk restoration, potential ADA compliance, maintenance access, and utility conflicts). This work will also include inlet spacing analysis calculations to ensure that when the new treatment units are located, they will meet City standards. - Review and selection of type of treatment BMP system (e.g., consider most appropriate BMP systems (with target of enhanced treatment for metals having Ecology’s GULD) such as modular wetland, Filterra, EcoStorm Plus, BioPod or other City requested treatment type BMPs). Depending on the individual site constraints, different type BMP systems may be recommended for AGENDA ITEM #1. a) different locations. Treatment options will be evaluated based on factors such as existing infrastructure, landscape integration, utility conflicts, spatial constraints, cost, and maintenance requirements. - Identification of potential utility conflicts and need for additional potholing. The existing survey base map will be the basis for the stormwater quality pre-design. Additional survey needs, including potholing, will also be identified as part of the pre-design work. Consultant will assess whether planned potholes for the proposed trunkline can also be used to provide data for WQ treatment BMPs. Any potholes required will be completed under the Task 54 Allowance Supplemental Surveying and Potholing. - Preliminary sizing that includes a simple hydrologic model (using WWHM or MGSFlood software) to estimate water quality treatment and bypass flow rates. Sizing and analysis will follow sizing requirements as set forth in the 2019 Surface Water Management Manual for Western Washington (2019 SWMMM) to provide enhanced treatment of the individual catchment areas. - Sizing of the treatment units. - Preliminary plan and profile for each proposed BMP. - Assessing roadway restoration that may be required (e.g., sidewalk reconstruction, ADA compliance, curb replacement, landscape restoration/irrigation, pipe installation for downstream connection, and utility conflicts). - Estimating the construction cost of the water quality retrofits.

Alia Company in the amount of $270,425.00 is available in the approved Surface Water Utility Capital Improvement Program budget for the Burnett Ave S and Williams Ave S Storm System Improvement Project (427.475517.015.594.31.63.000). 2025 Q1 Adjusted Budget - $2,689,687 YTD expenditures thru March 1, 2025 - $479,894 Remaining amount owed on existing contracts - $863,351 Change Order #1 Amount - $270,425 Remaining Budget if change order 1 is authorized - $1,076,017 SUMMARY OF ACTION: Construction of the Burnett Ave S and Williams Ave S Storm System Improvement Project began in October 2024. This project improves stormwater drainage and storm water quality through the installation of approximately 2,650 feet of new storm pipe, 49 structures, and two stormwater quality treatment units. Following trenching and storm system installation on Williams Ave S between the Cedar River and the intersection with Tobin Ave S, the project team determined that restoring pavement in that portion of the project through asphalt overlay will not be feasible. The right-of-way in this area contains a dense network of underground utilities whose installation over the years has resulted in multiple trench patches and a poor/uneven road surface. If the contractor were requested to restore pavement through grind and overlay, it would result in the same substandard pavement depth and uneven road surface that would not meet current city street restoration standards. Surface Water Engineering determined that a full depth road replacement in this area is needed to achieve a road surface and pavement depth that meets current city standards, with a higher quality and more durable (i.e. sustainable) product compared to the original plan. This deviation from the original pavement restoration approach requires executing Change Order 1 to increase the Hot-Mix Asphalt (HMA) and Crushed Surface Top Course (CSTC) quantities. Change Order 1 adds a new bid item to pay forfull depth road excavation on Williams Ave S from the intersection with S Tobin S to roughly the Williams AGENDA ITEM #2. a) Ave S bridge over the Cedar Riverat a cost of$119,925.Additionally, Change Order 1 increases the quantity of trench backfill associated with storm system installation work on the entire project.
