Recreation and Conservation Office (RCO) Amendment No. 2
ISSUE
Authorize the Mayor to sign Amendment No. 2 to the RCD grant agreement 18-083 for the Riverton Creek
Flap Gate Removal Project.
BACKGROUND
The City entered into a grant agreement (RCO # 17-1048R) for design and construction of the Riverton Creek
Flapgate Removal Project on January 31, 2018.
DISCUSSION
The CUv. through VVR|A 8, requested a cost increase to accommodate design changes that resulted from
Salmon Recovery Funding Board comments on the preliminary design submittal. Amendment No. 2 includes
$100.000 in additional funding from the RC{}, as well as o reiteration of the special conditions and slight
modification to the agreement description.
FISCAL IMPACT
Sponsor match will come primarily from Cooperative Watershed Management (CVVM) funds, which are
allocated from the King County Flood Control District to VVR|Aa 7`8.8 & 10 to help implement high priority
projects. The WRIA 9 Forum approved $140,000 for the Riverton Creek Flapgate Removal Project on May 9,
2019 and that agreement will become available in the fall of 2019. The remainder of the match will come from
dedicated 2019-2020 Surface Water Utility Revenue. The overall C|P budget will be increased due tothis
additional funding.

Request for returned funds
Date of request: May 1, 2019
Lead Entity: WRIA 9 Green Duwamish and Central Puget Sound
Project Title: Riverton Creek Flapgate Removal Project
PRISM #: 17-1048
Project Sponsor: City of Tukwila
Amount being requested: $241,436
Please provide the following:
1. Justification and need for the cost increase (and any uncertainties associated with the amount)
Cost increases include (see attached drawings):
• Habitat enhancement: add LWD in lower channel (addresses SRFB comment)
• Habitat enhancement: step channel down at confluence w/ Duwamish R. to create
salmonid access at low water conditions; current design shows no access at elevations
below el —+2; Increase bridge abutment wall height to account for channel grade step
down
• Habitat enhancement: modify LWD installation at outlet from pool to allow slower
release of water at low tide, and thus, create pool in backwater area during low water
2. Timeline for allocating funds
The need for funding is immediate. Maintaining the construction schedule for the 2020 fish
window depends on this additional funding so that the city can make progress on design and
submit permit applications.
3. Description of LE approval process
The WRIA 9 Lead Entity Implementation and Technical Committee evaluates and approves most
project cost and scope increases. Projects requests requiring involvement from the Watershed
Ecosystem Forum are elevated. Most projects in good standing with clear justification for the
request are evaluated at the ITC level. Project sponsors are requested to attend and present the
request, or if the sponsor cannot attend, the lead entity coordinator or another proxy will
present. Upon approval the lead entity coordinator will submit the request to RCO. The project
has already received preliminary approval by the ITC. The sponsor will be presenting this request
to the ITC on February 20t' for final approval.
4. Description of project
The City of Tukwila will improve habitat conditions along the lower 1300 lineal feet of Riverton
Creek and restore fish access between the creek and the Duwamish River, providing off -channel
rearing habitat for salmonids, including the ESA listed Chinook salmon, steelhead, and bull trout.
The property is located along the Green River Trail on the left bank of the Duwamish River at RM
6.5, all within the tidally influenced estuary. Restoration will include a) adding large wood to the
creek channel, b) removing invasive vegetation and installing native plants to establish a native
riparian buffer along 400 ft on the Duwamish River and on each side of the creek, including a
acre emergent wetland, c) removing two perched culverts with flapgates d) installing a new
pedestrian bridge for the Green River Trail and structural reinforcement to the adjacent
roadway (Tukwila International Blvd). The site is across the river from Duwamish Gardens and
Chinook Wind habitat restoration projects, and adjacent to the SR 599 off ramp to Tukwila
International Boulevard. Reconnecting the creek to the river requires construction of a
structural sheet pile wall to protect the southern Tukwila International Boulevard bridge
abutment. The pedestrian bridge and an interpretive sign will provide an opportunity for people
to experience nature and view wildlife. This Duwamish River bank is categorized as 'critical' on
the Muckleshoot Tribes Sun Aspect Map, identifying a most critical need of shade based on solar
aspect.
