INFORMATIONAL MEMORANDUM
TO: Transportation and Infrastructure Services Committee Meeting
FROM: Hari Ponnekanti, Public Works Director/City Engineer
BY: Mike Perfetti, Senior Surface Water Project Manager
CC: Mayor Ekberg
DATE: April 1, 2022
SUBJECT: Riverton Creek Flapgate Removal Project
Project No. 99830103, Contract No. 20-075
Change Order No.1
ISSUE
Approve Change Order No. 1 to Contract 20-075 with AtWork! Commercial Enterprises, LLC of Bellevue, WA.
BACKGROUND
At Work! Commercial Enterprises is nearing completion of the initial clearing, planting and 1 -year maintenance period
associated with the Riverton Creek Flapgate Removal Project, Phase 2. This phase restored 1.48 acres of native riparian
vegetation along Riverton Creek and 0.45 acres along the Duwamish River.
DISCUSSION
To protect this investment, enable success, and meet grant commitments, the City will maintain the restoration work for a 10 -
year period. Generally, the first 3 or so years are the most critical periods of plant establishment, where plants need
supplemental water and weed control to survive and outcompete invasive, non-native plants such as Himalayan Blackberry
and Reed Canary grass. Change Order No. 1 will increase the contract amount and provide a two-year contract extension
ending on April 30, 2024, which will allow AtWork! to provide restoration during this critical establishment period.
FISCAL IMPACT (All amounts include sales tax)
The Riverton Creek Flap Gate Removal Project construction, including both phases, was initially budgeted at $918,000. The
low bid for the first phase, which was recently awarded, exceeded the budget and is utilizing all CIP funds dedicated for this
project. The initial AtWork! contract was funded through Surface Water Utility Funds transferred from the 205 Levee
Certification CIP and WRIA 9/CWM grant funds.
Change order No. 1 includes additional compensation of $57,031.80, raising the tax -inclusive contract total to $163,122.40.
This compensation will utilize project contingency allocated in the initial contract and the remainder from the 2022 CIP of the
Green the Green Program CIP. The City has a pending no -match grant application for $40,000 to assist with funding this work.
Contract Amount Fund Source Budget
Initial Contract $106,090.60 205 Levee CIP $66,669.66
Change Order No. 1 $57,031.80 Green the Green CIP 46,452.74
WRIA 9/CWM Grant 50 000.00

RECOMMENDATION
Council is being asked to approve Contract 20-075 Change Order No. 1 for the Riverton Creek Flap Gate Removal Project
Restoration Phase II to AtWork Commercial Enterprises, LLC in the amount of $57,031.80 and consider this item on the
Consent Agenda at the April 18, 2022 Regular Meeting.

CITY OF TUKWILA CAPITAL PROJECT SUMMARY
2021 to 2026
PROJECT: Tukwila 205 Levee Certification Project No. 91341203
DESCRIPTION: Reconstruct the Tukwila 205 Levee to provide 500 -year level of flood protection and obtain levee certification.
The US Army Corps of Engineers no longer provides levee certification services to federally authorized
levees. The existing certification expired in August 2013. Certification is required for the Federal Emergency
JUSTIFICATION: Management Agency to accreditate the levee system as providing a 100 -year level of flood protection. A
study of the Tukwila 205 Levee found approximately 80% of the levee could not be certified in its current
condition and will require repair or reconstruction.
STATUS: A levee assessment has been completed.
MAINT. IMPACT:
Certification process is expected to lead to additional levee repair projects that are required to meet the
certification criteria. Certification is valid for a 10 -year period.
The City has petitioned the King County Flood Control District to make levee improvements to upgrade the 205
Levee to provide a minimum of 100 -year level of protection, and where construction is needed, construct to a
COMMENT: 500 -year level of protection. KCFCD has agreed to begin design of several projects in 2020, which will take
approximately 15 years to complete and will require extensive work with the City of Tukwila and property
owners. A full time employee to monitor this project will be required and listed in 2021 through 2026.
