City of Tukwila <br />Allan Ekberg, Mayor <br />TO: Transportation & Infrastructure Committe <br />FROM: Bob Giberson, Public Works Director <br />BY: Mike Perfetti, Habitat Project Manager <br />CC: Mayor Ekberg <br />DATE: April 07, 2017 <br />SUBJECT: Riverton Creek Flapgate Removal <br />Project No. 99830103 <br />Consultant Selection and Agreement <br />ISSUE <br />Approve OTAK, Inc. to design the Riverton Creek Flapgate Removal Project. <br />17_Ta:(�1T�1�P►17 <br />The Riverton Creek Flapgate Removal Project began in 1999 with the goal of restoring salmon access to Riverton Creek <br />through the removal of culverts and flapgates at the mouth, which are a partial barrier to salmon migration. Early work <br />included project feasibility and preliminary design plans, which could be used to apply for project grant funding. Now, with <br />committed City funding and two grant applications pending approval, City staff would like to resume project design and <br />permitting. <br />DISCUSSION <br />The current MRSC Consultant Roster was reviewed and four firms were short- listed to submit proposals. The firms were: <br />DEA; Herrera; OTAK; and Parametrix. The proposals were reviewed and scored against stated criteria by a panel of three <br />staff members. OTAK received the highest score and was selected as the firm that best met the project's requirements. <br />OTAK was also recently contracted by the City to assist with the City's NPDES Phase II — Low Impact Development (LID) <br />code update. <br />FINANCIAL IMPACT <br />After negotiations, OTAK will provide design and permitting services for the Riverton Creek Flapgate Removal Project for a <br />fee of $105,363.00 and the 2017 CIP has $108,000.00 budgeted. There is also a 2016 Puget Sound Acquisition and <br />Restoration (PSAR) grant awaiting a state appropriation of up to $551,070.00, which is anticipated to become available <br />following the current legislative session. <br />Council is being asked to approve the design consultant agreement with OTAK, Inc. in the amount of $105,363.00 for the <br />Riverton Creek Flapgate Removal Project and consider this item on the Consent Agenda at the April 17, 2017 Regular <br />Meeting. <br />Attachments: Location Map <br />2017 CIP, Page 108 <br />Consultant Agreement <br />W: \PW Eng \PROJECTS\A- DR Projects\Riverton Flap Gate Removal (99830103 98 -DR03) \Consultant Selection\Phase 2 \scoping \Info Memo Otak PE 040717 gl SM.docx 15 <br />
