It is a priority project with the Water Resource Inventory (WRIA) 9 and the Salmon <br />Recovery Fund Board. The goals of the project are to restore fish passage between Gilliam Creek and <br />the Green River, enhance habitat, and maintain or improve flood protection, maintenance and operation <br />of the tide gate system. <br />ANALYSIS <br />This contract amendment will include nine tasks to further design development and support upcoming <br />National Oceanic and Atmospheric Administration (NOAA) Grant application(s). Tukwila used Otak's <br />work product to apply for two NOAA grants ($19.7M/22.6M) in 2023, both were unsuccessful. NOAA <br />provided Tukwila feedback to improve future applications. This project has a complex set of <br />requirements in one of the more complex urban settings for fish passage with State 1-405, local arterial <br />roads (66th Ave S & Tukwila Pkwy) and the Federal 205-levee. The project is adapting to feedback, as <br />well as recent damage to the upstream streambanks at the 66th culvert inlet <br />FISCAL IMPACT <br />Otak has provided a cost estimate not to exceed $138,270.00 to perform additional design and <br />engineering services. Total grant funding for this project is $1,350,000.00. <br />Otak Contract 22-068 (original) <br />Otak Contract 23-191* <br />Otak Contract 24-093 <br />24-093 Amendment No. 1 <br />Grants <br />Total: <br />Consultant <br />$330,622.00 <br />($39,500.00) <br />$402,934.42 <br />$138,270.00 <br />Budget <br />$1,350,000.00 <br />$871,826.42 $1,350,000.00 <br />* = Contract amount is the balance remaining in expired contract 22-068. <br />RECOMMENDATION <br />Council is being asked to approve Amendment No. 1 to Contract 24-093 with Otak for additional design <br />and engineering services in the amount of $138,270.00 and to consider this item on the Consent Agenda <br />at the October 7, 2024, Regular Council Meeting. <br />Attachments: CIP '23 '28, Pg 81.pdf, Contract 24-093 Amend #1.pdf <br />43 <br />
