Consultant Selection and Agreement
ISSUE
Approve OTAK, Inc. to design the Riverton Creek Flapgate Removal Project.
17_Ta:(�1T�1�P►17
The Riverton Creek Flapgate Removal Project began in 1999 with the goal of restoring salmon access to Riverton Creek
through the removal of culverts and flapgates at the mouth, which are a partial barrier to salmon migration. Early work
included project feasibility and preliminary design plans, which could be used to apply for project grant funding. Now, with
committed City funding and two grant applications pending approval, City staff would like to resume project design and
permitting.
DISCUSSION
The current MRSC Consultant Roster was reviewed and four firms were short- listed to submit proposals. The firms were:
DEA; Herrera; OTAK; and Parametrix. The proposals were reviewed and scored against stated criteria by a panel of three
staff members. OTAK received the highest score and was selected as the firm that best met the project's requirements.
OTAK was also recently contracted by the City to assist with the City's NPDES Phase II — Low Impact Development (LID)
code update.
FINANCIAL IMPACT
After negotiations, OTAK will provide design and permitting services for the Riverton Creek Flapgate Removal Project for a
fee of $105,363.00 and the 2017 CIP has $108,000.00 budgeted. There is also a 2016 Puget Sound Acquisition and
Restoration (PSAR) grant awaiting a state appropriation of up to $551,070.00, which is anticipated to become available
following the current legislative session.
Council is being asked to approve the design consultant agreement with OTAK, Inc. in the amount of $105,363.00 for the
Riverton Creek Flapgate Removal Project and consider this item on the Consent Agenda at the April 17, 2017 Regular
Meeting.

Exhibit A - Scope of Work
Riverton Creek Flapgate Removal Project
City of Tukwila
April 03, 2017
Otak Project No. 32740
Introduction and Background
Tukwila has adopted policies to identify and restore habitat and ecological function along the
Duwamish River where restoration can succeed with existing conditions and adjacent uses. The
removal of flapgates and perched culverts at the outlet of Riverton Creek is a key opportunity to
remove a fish barrier and re -open a historical stream outfall and restore rearing and migrating habitat
adjacent to the Duwamish.
For this project, the City is requesting Otak to finalize the design of the Riverton Creek Flap Gate
Removal improvements initiated by a previous consultant working for the City. This will include
taking the 75- percent design to final design and preparing construction documents, updating
environmental assessment reports and technical supporting documents, and providing technical
support to obtain permits. This project may also include construction support services.
Based on our discussions with the City, the project will be accomplished in two phases — Phase 1 -
Intake Review and Charter Meeting, Phase 2 - Permitting and Final Design. If construction support
or other supplemental services are requested, a supplement will be submitted to add Phase 3
services. This scope of work describes activities within the first two phases — initially with broad
terms, and then with specific tasks for each phase.
Phase I— Intake Review and Charter Meeting
The first step we will take is performing a detailed review of the 75- percent design including all
reports and supporting documentation made available by the City. This review will include a field
visit to assess the existing conditions and note any discrepancies from the data and descriptions
from the 75- percent design which was performed from 2009 -2011. The Intake Review will also
include development of a simple Permitting Strategy Plan that identifies all regulatory requirements
and design criteria for various agencies so that permitability of all project elements can be
confirmed. After the Intake Review, we will facilitate a project Charter Meeting with Tukwila to
assess how project challenges have been addressed as part of the completed existing design (75-
percent level) and what will need to be addressed by the Otak team.
After the Charter Meeting has been completed, but prior to completion of Phase 1, Otak will review
the scope of work for Phase 2 and, if required and authorized by the City, make any adjustments in
the scope, schedule and budget for City review and contract processing. Upon completion of Phase
23
1, a contract supplement will be prepared, if necessary, to carry the project into final design and
construction document preparation. Otak will not proceed beyond Phase 1 Intake Review and
Charter Meeting without authorization of the City.
Phase 2 — Permitting and Final Design
In Phase 2, Otak will bring the 75- percent plans completed by another consultant up to a 100 -
percent complete construction documents, including plans, specifications, and construction cost
estimate (PS &E).
Project Criteria
The City will designate the project parameters and design criteria. Reports and plans, to the extent
feasible, shall be developed in accordance with the latest edition and amendments as of the date of
the Notice to Proceed, of the following documents. Changes in any design standards or
requirements after work has begun may result in Extra Work.
