INFORMATIONAL MEMORANDUM
TO: Transportation and Infrastructure Services Committee
FROM: Hari Ponnekanti, Public Works Director
BY: Sherry Edquid, Levee and Floodplain Project Manager
CC: Mayor Allan Ekberg
DATE: June 2, 2023
SUBJECT: Wetland and Environmental Mitigation
Consultant Selection
Multiple Project Nos.
ISSUE
Execute a contract with Raedeke Associates Inc. to provide consultant services to fulfill the plant
establishment and monitoring requirements at landscape mitigation sites associated with four
completed capital projects.
BACKGROUND
Projects undertaken by the City that are within established Shoreline or Wetland buffer areas are subject
to the Shoreline Management ordinances (Ord. 2625, Ord. 2626, Ord. 2627). Each project listed below
has mandatory plant establishment and monitoring requirements that were established in their approved
permits. The purpose of this contract is to comply with the permit requirements by developing
documentation and plans as needed to meet required mitigation performance standards.
• Southcenter Parkway Extension (98400437)
• Tukwila Urban Center Pedestrian Bridge (90510403)
• 42nd Ave S. Bridge Phase III (99410303)
• Interurban Avenue Improvements (90301402)
The scope of work entails site assessment, review of existing documentation, monitoring, compliance
documentation and adaptive management planning to achieve permit compliance and project closeout.
Monitoring in the past has been done by a different consultant with inconsistent results. Staff
recommended not renewing the contract. A flood event in 2020 damaged a portion of the mitigation area
associated with the Tukwila Urban Center Pedestrian Bridge and FEMA monies have been obtained to
repair the damage.
DISCUSSION
The City issued a Request for Qualifications (RFQ) and three consultant firms submitted proposals in
response. Raedeke Associates Inc. was selected based on their qualifications and years of
experience performing similar work for various municipalities in the Puget Sound region.

Scope of Services
For Professional Services Agreement
This document shall serve as an Agreement for Professional Services between Raedeke
Associates, Inc. and the City of Tukwila for the project known as:
City of Tukwila – Mitigation Site Monitoring
RAI#2023-032
- 001 Tukwila Urban Center Pedestrian Bridge
- 002 Southcenter Parkway Extension
- 003 Interurban Avenue Improvements
- 004 42nd Avenue South Phase III
PROJECT LOCATION
The project consists of 4 separate mitigation sites: Southcenter Parkway Extension, Interurban
Avenue Improvements, Tukwila Urban Center Pedestrian Bridge, and 42nd Avenue South Phase
III. All sites to be evaluated are located in the City of Tukwila, Washington. A list of mitigation
sites received from Sherry Edquid, as well as maps retrieved on-line from the City of Tukwila and
King County websites depict the study sites.
PROJECT SUMMARY
This Agreement authorizes Raedeke Associates, Inc. to provide an evaluation of the sites listed
above, to prepare new mitigation plans for each site, to oversee construction implementation, and
to conduct performance monitoring at each site after construction has completed.
PERFORMANCE OF SERVICES
Services are performed per the U. S. Army Corps of Engineers (COE) Wetlands Delineation
Manual (Environmental Laboratory 1987), as updated for this area by the regional supplement to
the COE wetland delineation manual for the Western Mountains, Valleys, and Coast Region
(COE 2010). The COE wetlands manual is required by state law (WAC 173-22-035, as revised)
for all local jurisdictions.
The ordinary high water mark (OHWM) of streams will be determined using definitions provided
by the Washington State Shorelines Management Act of 1971: “that mark that will be found by
examining the bed and banks and ascertaining where the presence and action of waters are so
common and usual, and so long continued in all ordinary years, as to mark upon the soil a
character distinct from that of the abutting upland, in respect to vegetation.” (RCW
90.58.030(2)(b) and WAC173-22-030(6). The OHWM will be delineated using procedures
outlined in the 1994 Washington Department of Ecology Shoreline Administrators Manual.

PROJECT SUMMARY
This Agreement authorizes Raedeke Associates, Inc. to prepare a new mitigation plan for the
Tukwila Urban Center Pedestrian Bridge mitigation site and to provide oversight during
construction activities.
SCOPE OF WORK
• Project Initiation and Background Review: This task includes initial coordination with the
City of Tukwila and review of background information, including available reference maps and
documents from regulatory or resource agencies, including information on wetlands, streams,
and soils. We will utilize information and documents provided by the City.
• Field Evaluation: We will utilize previously collected information on vegetation, soils, and
hydrology to support our findings, as well as other notes and supplemental aerial imagery
pertinent to making a determination of wetland and buffer extent. Upon review of this
information, we will perform site visits to gather additional data and evaluate the extent of
wetlands and buffers, and to identify deficiencies from permit performance standards. This
task assumes up to 4-staff hours.
• Summary Memo: This task involves preparation of a technical memorandum summarizing
the conditions of the site. The report is intended to provide the City of Tukwila with a
preliminary understanding of status of the mitigation site relative to the goals and objectives
of the mitigation effort.
• Mitigation Plan: This task involves preparation of new mitigation plans created in CAD, if
necessary (assumes up to 15 staff-hours).
• Construction Site Visits: This task includes site visits for pre-construction and mid-
construction meetings to coordinate with the City and their contractors, and inspect to confirm
the mitigation site is being constructed per the approved new plans (assumes up to 12 staff-
hours).
• Performance Monitoring: The project biologist would conduct a site visit during August or
September to document existing site conditions, including plant survival, health, and invasive
species presence, and to determine if the site is meeting the required performance
standards. During the monitoring visit, the project biologist would count plants and estimate
vegetative cover in the sample plots, and take photos to document the health of the mitigation
area (assumes up to 4 hours for two staff, for a total of 8 staff-hours)
• Performance Monitoring Report: After completion of the monitoring site visit, Raedeke
Associates, Inc. will prepare a technical memorandum to serve as documentation of the
existing conditions for the site. This report will include data collected in the mitigation areas,
a color photo-plate depicting the mitigation site, and graphics showing the general
configuration of the mitigation site and its plantings. The cost estimate includes one round of
review and revision (up to 1 staff-hour) in response to city comments.
186
• Project Coordination and Administration: This task includes correspondence and
coordination with the City of Tukwila or their consultants with regard to scheduling and
information acquisition for the project and to provide in-house administration as necessary
during the course of the project (assumes up to 1 staff-hours).
