CITY OF TUKWILA nnlnitial Signed by: J KAAS k.G(,c,bd, Thomas McLeod, Mayor ATTEST/AUTHENTICATED: ,--Signed by: Andy Youn-Barnett, City Clerk APPROVED AS TO FORM: Signed by: C�. S d Office of the City Attorney CONSULTANT: Northwest Hydraulic Consultant, Inc. By. ®. Printed Name: Vaughn Collins Title: Principal CA revised May 2020 Page 5 Scope of Work Background and Understanding In 2015, Northwest Hydraulic Consultants completed an interior drainage assessment for the "Tukwila 205" levee system as one part of a levee certification study. In early 2025, the results of the study were packaged for a FEMA LOMR with reporting, workmaps, and annotated FIRMs. The interior drainage flood hazard areas from this study show new interior drainage flooding around the north side of Southcenter Mall. This scope of work provides additional documentation to explain this change to various interested parties, minor updates to the FEMA package, and adds an on-call task for further coordination should the need arise. Work to be Completed Under This Contract Task 1: Marl Revision and Summary Memorandum a) NHC will revise the flood mapping shown on the workmap and annotated FIRM to reflect recent changes at the corner of Baker Blvd and Andover Park E resulting from the Prose Southcenter development. The interior drainage letter previously prepared for FEMA will also be updated to discuss the revisions. b) NHC will prepare a summary memorandum for internal City use. The memorandum will describe: • An overview of levee certification generally, why certification of the Tukwila 205 levee is being pursued, and the SQRA completed by the Corps. • A narrative history of flood mapping around Southcenter with a focus on the depression near Macy's. The narrative will include a brief historical timeline of key changes to NFIP regulations, and a timeline of prior interior drainage mapping efforts. • Parcels affected bythe newflood mapping, including a table of parcel numbers and a figure showing their locations • Options for Macy's, and the City, including the City potentially taking ownership or easement of the Southcenter pump station. The description will include a high-level discussion of the implications for Macy's should it be mapped in the floodplain as it pertains to future development, as well as insurance requirements. c) NHC will attend three meetings with City management and/or private property representatives. Deliverables: • Revised Workmap, annotated FIRMs, and summary updated FEMA report to include changes from Prose Southcenter development. • Summary memorandum for City use (draft and final) • PowerPoint presentation for use in meetings Assumptions: • Because the Prose Southcenter information is in pdf format, revised grading and mapping will be approximate based on the information in the pdfs. • Meetings will be led by City staff with NHC support. NHC support will consist of preparing a brief PowerPoint presentation and being available to answer questions at the meetings. • The PowerPoint presentation will cover the results and findings documented in the summary memorandum. • The scope does not include any additional modeling to see how the FIRM would change if the Southcenter pump station were to be included. Task 2: Respond to FEMA Comments Under this task, NHC will respond to further FEMA comments should they arise. NHC has 24 hours budgeted under this task. As it is impossible to predict in advance what comments FEMA will have, an amendment may be required if addressing the comments requires effort above this estimate. Task 3: Miscellaneous Support Under this task, the City may request floodplain management support from NHC on an as -needed basis. The support is anticipated to include minor consultations, reviews, phone calls, or meetings. This taskwill not be billed without prior authorization from the City. To authorize work under this task, NHC will provide an estimated of the number of hours required to complete the requested support and the City will authorize the request. Approval will be via email. Budget: The estimated budget for this scope of work is $32,350. A detailed budget breakdown including hours and labor categories is shown below.
