Exhibit A
Madsen Creek Improvement Project - Phase 1
Scope of Work
Background
The flood and sediment deposition problems experienced along Madsen Creek are
typical of small streams in reaches of transitioning channel slope. Madsen Creek
collects runoff from a large upland glacial moraine plateau and then descends 400 feet
through a steep hillside ravine before flowing onto the floodplain of the Cedar River.
The creek slope begins to flatten as it emerges from the ravine and flows across a small
alluvial fan, and further flattens as it flows across the Cedar River floodplain. The rapid
decrease in channel slope reduces the stream's ability to convey both water and
sediment, causing sediment to deposit within the channel. To address sediment
deposition and reduce flooding, King County constructed a sediment collection basin at
the outlet of the ravine and a high flow flood bypass channel extending from the
sediment basin to the Cedar River. The system has performed relatively well since it
was installed in the 70s or 80s; however, after 30 to 40 years of use, the City has
initiated this project to determine if modifications can be made to reduce or solve
recurrent flood problem at several sites within the system.
Based upon initial inspection of the system, review of existing project documents, and
discussions with City staff, the following scope of work describes the tasks that will be
completed by the consultant team to evaluate the existing system and to identify both
near-term and long-term actions to reduce or eliminate flooding. For organization
purposes, the project will be divided into two phases: Phase 1 will be an Existing
Condition Assessment, and Phase 2 will include Preliminary Design and Analysis.

Task . Survey an ase Map Creation
Task Lead: PGS
Approach: PGS will complete a detailed topographic survey of the channel network to
collect the data required to complete the hydrologic, hydraulic, geomorphic, and
environmental assessment tasks, and to prepare the project base map needed to
identify, lay-out, and develop alternative solutions. With help from the City, PGS will
obtain right-of-entry permissions as needed to access private property. The survey will
begin upstream from the sediment basin and continue downstream to the Cedar River
along both the constructed high flow bypass and the low flow channel, including
detailed survey of:
➢ Sediment basin bathymetry and upland topography, along with all visible inlet,
outlet, and bypass structures (weirs and culverts)

by the hydraulic modeling team. Formats will be determined prior to mapping
efforts.
Task 6. Environmental Assessment
Task Lead: Herrera
Available environmental data will be gathered and reviewed as part of Task 2. Data will
be used to create layers within the GIS base map which will be used while conducting
field work.
Herrera biologists will conduct a site visit to assess existing habitat conditions and
ecological functions provided at the project site, delineate wetlands, and identify the
ordinary high-water mark (OHWM) of Madsen Creek.
Fish Habitat. Biologists will take measurements and notes on the characteristics of
aquatic habitat and fish species presence from the sedimentation basin downstream to
the confluences of Madsen Creek and the high flow bypass channel with the Cedar River
(e.g., substrate, water depth, inlet/outlet conditions, fish passage barriers,vegetation,
large woody debris, pools, etc.). The habitat characterization work will focus on habitat
for key salmonid species that currently use the creek, and that may use it in the future if
habitat improvements are implemented.
Wetlands. Biologists will delineate the boundaries of identified wetlands located within
the project area. Wetland delineations will extend to within 200 feet of the project site
limits (the study area) to determine if buffers associated with off-site wetlands will be
affected by the project. Where property access is not provided, Herrera will estimate
wetland conditions from the project site and other publicly accessible areas. The
wetland determination and delineation will be conducted using the routine
determination method outlined in the U.S. Army Corps of Engineers (USACE) Wetland
Delineation Manual, and the Interim Regional Supplement to the Corps of Engineers
Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region.
Delineated wetlands will be classified according to US Fish and Wildlife Service (USFWS)
and hydrogeomorphic classification systems and typed in accordance with City of
Renton and King County codes and Washington State Department of Ecology (Ecology)
Washington State Wetland Rating Systems for Western Washington. The functions of
wetlands will be assessed using the Ecology rating system. The City of Renton and King
County codes will be used to identify the regulated buffer widths of the wetlands.
Biologists will flag the boundaries of the wetlands and all test plots.
Streams. The OHWM will be determined using the definition set forth in WAC 173-22-
030(11) and the guidance outlined in Determining the Ordinary High Water Mark for
Shoreline Management Act Compliance in Washington State. This involves using
sequentially numbered flags to identify the OHWM as evidenced by abrupt changes in
topography, dominance of perennial vegetation, sediment deposits, drift lines, and signs
of scouring. Biologists will flag the boundaries of the OHWM. The City of Renton and
King County codes will be used to type Madsen Creek and determine the regulated
buffer width.
Hydrologic Monitoring. Herrera will provide two field technicians to install hydrologic
monitoring equipment, including a stream gage near the 149th Ave SE culvert and up to
six ground water monitoring wells. Several wells will be installed in the wetland located
at the confluence of Madsen Creek and the Cedar River, in addition to locations where
Madsen Creek may be realigned and/or wetlands created in the project area. The
stream gage and monitoring wells will be used to monitor surface water and shallow
groundwater levels. The stream gage and monitoring wells will be equipped with a
water level data logger that will be programmed to continuously record water levels
once per hour. One barometric pressure data logger will also be installed on the site at a
secure location to correct the absolute pressure measurements for the stream gage and
monitoring wells for atmospheric pressure. The monitoring wells will be installed by
hand using an auger. The depth of each monitoring well will exceed five feet below the
ground surface but will be less than 10 feet deep (monitoring wells less than 10 feet
deep are exempt from Ecology's well construction and reporting requirements).
After the stream gage and monitoring wells are complete, Herrera will return to the site
on three occasions to upload data and ensure the data loggers are functioning properly.
The ground surface and top elevation of the stream gage and each monitoring well will
be surveyed by others. This scope does not include decommissioning of the stream gage
or wells after monitoring is complete.
Upon completion of the environmental assessment, Herrera will prepare a written
summary that will describe fish species present in the study area, and the characteristics
of aquatic habitat, wetland, and riparian land cover throughout the study area. It will
also summarize the methods and results of the delineations and habitat assessment.
The summary will present the classification of delineated critical areas and regulated
buffer widths and the results of hydrologic monitoring. The preliminary maps will be
refined based on field investigations to create final maps that document existing
conditions.
Assessment results will be presented to the City during the Task 11 Existing Conditions
meeting.
Assumptions:
➢ Off-site wetlands within 200 feet of the project site will be evaluated based on
available property access.
➢ Field work will be conducted by teams of two biologists in up to five 10-hour
field days.
➢ Wetland, OHWM, and test plot flags will be surveyed by PGS. Herrera biologists
will provide field maps of all flag locations to PGS.
➢ Up to six monitoring wells and one staff gage will be installed and monitored at
the site.
➢ Installation of monitoring equipment will be performed by two scientists in two
field days; data collection will be performed by one scientist on three separate
visits.
Deliverables:
➢ Draft and final written documentation will be prepared for inclusion in the Task
11 Existing Conditions report.
➢ Presentation of results will take place in conjunction with Task 11 Existing
Conditions presentation.
Task 7. Permit Identification anStrategy
Task Lead: Herrera
The permitting analysis will identify the full range of permits and approvals that may
apply to proposed project solutions. The study area contains and is adjacent to multiple
regulated environmentally sensitive areas including the Cedar River, Madsen Creek,
wetlands, and buffers. These areas will be identified and mapped during the
Environmental Analysis (Task 6) and added to the GIS project base map. The footprint
of proposed project actions will be added to the base map to determine if they would
impact sensitive areas and whether they can be refined to avoid or minimize impacts.
Members of both the Environmental and Permitting teams will participate in the
identification and evaluation of proposed actions with the goal to minimize impacts to
sensitive areas to improve the ability to obtain required permits and to minimize/avoid
the need for mitigation. Once the actions have been identified, Herrera will prepare a
written summary that presents federal, state, and local regulatory implications that
pertain to the project, and evaluates the permitting feasibility and relative difficulty of
the proposed project actions. The summary will include a permit matrix that identifies
the suite of permits required for each action, and for each permit, the responsible
regulatory agency, required permit support documentation, and the estimated review
timelines.
A summary of potential permits will be presented as part of the Task 11 Existing
Condition presentation.
Assumptions:
➢ This task does not include meeting with regulatory agencies.
Deliverables:
➢ Draft and final written documentation will be prepared to be included in the
Task 11 Existing Conditions Report.
➢ Presentation of results will take place in conjunction with Task 11 Existing
Conditions presentation.
"ask 8. Hydrology
Task Lead: WSE
Madsen Creek drains approximately 2.2 square miles on the Fairwood Plateau, a highly
urbanized area south of the Cedar River and east of Renton. Land-use on the plateau
includes high density residential and golf course development. Downstream of the
plateau basin land-use includes areas of steep forested hillslopes, a mobile home park, a
large Church, high density residential development, and the less developed floodplain of
the Cedar River. For this project an existing HSPF hydrologic model of the basin will be
obtained, refined and run to provide hydrologic data for analysis and input for the
hydraulic model described in Task 9.
The HSPF model will have 10 to 15 subbasins delineated at significant hydraulic controls
and key points of interest. Land use and soils data for the model will come from past
mapping studies, refined as necessary using aerial photography to capture significant
recent development in the basin. The hydrologic model will include several large
stormwater management facilities including the West Basin pond, the New Life Church
detention facility, and if hydraulically significant the sedimentation pond near
Wonderland Estates.
Rainfall and evaporation data to drive the HSPF model will be obtained from local gages
and past studies. The period of record will be extended from approximately 1949 to
2017, allowing simulation of all recent and historical flood events. Flow frequency and
flow duration analyses will be conducted at up to 10 locations to characterize hydrology
at key points of interest. Environmental low flow analyses will also be performed at
locations as needed for the environmental assessment described in Task 6. Design flow
hydrographs will be extracted from the HSPF output and formatted for use in the
hydraulic model. The results of the investigation will be summarized and included in the
Existing Condition report and presented to the City during the Existing Condition
presentation.
If proposed project actions will alter flow distribution within the system, the HSPF model
will be modified to reflect those actions and post project data will be extracted and
analyzed to inform development and selection of various project actions.
Assumptions:
➢ The start date and time step for hydrologic modeling will be based on
meteorologic data available from previous studies—the period of record will be
extended as possible using readily available precipitation data.
➢ Control structure data for the detention facilities will be provided by the City.
Deliverables:
➢ Updated HSPF model
➢ Flow frequency results
➢ Flow data for use as inputs to hydraulic modeling and environmental
assessments
➢ Flow data as required to evaluate sediment transport and deposition
➢ Written Summary to be included in the Existing Condition report (Task 11).
➢ Hydrologic analysis results will be presented during the Existing Condition
presentation (Task 11).
Task 9. Hydraulic Modeling
A HEC-RAS hydraulic model of the stream network will be developed and used to
evaluate existing conditions and proposed alternative solutions. The complexities of the
lower portions of the conveyance system within the Cedar River floodplain are best
characterized using a one-dimensional (1D) split-flow HEC-RAS model because it can
simulate natural as well as constructed channels along with multiple hydraulic
structures (culverts, weirs, etc.),junctions and flow splits. Several culvert crossings are
choked with sediment, leading to limited conveyance capacity and frequently
surcharged conditions, which will be represented in the model. Weirs will be added to
represent any levee or bank overtopping locations, along with the flow split at the 149th
Ave SE crossing where high flows are diverted north along the roadway ditch (former
main channel). The detailed topographic and structural survey from Task 4 will be used
to develop the geometric inputs to the hydraulic model and the model will be run with
unsteady flow assumptions, using upstream as well as lateral inflow hydrographs
(largely from the local stormwater drainage system) provided by the HSPF modeling
from Task 8.
HEC-RAS includes advanced capabilities to simulate two-dimensional (2D) flow. If
beneficial to the project, a 2D model will be developed for the lower reach of the
natural Madsen Creek channel as it passes through Ron Regis Park to better characterize
the flow patterns and possible flood risk within the park and to neighboring private
property. A 2D model may also be developed further upstream to cover the natural
channel reach and adjacent floodplain along New Life Church; however, it is likely this
reach can be reasonably and accurately represented using 1D cross sections. WSE will
obtain the City's approval before performing any 2D modeling.
The HEC-RAS model will be utilized to evaluate the performance of proposed actions
during the design phase of the project. The model will be run to evaluate system
performance over a range of discharges, including the 100-year event which will be the
design flood.
The assumptions and results of the investigation will be summarized and included in the
Existing Conditions Report and presented during the Existing Condition presentation
(Task 11).
Assumptions:
➢ If observed high water marks from previous floods can be identified and
surveyed, WSE will attempt to calibration the HEC-RAS model. If high water
marks do not exist, WSE will set model parameters based upon judgement and
experience.
Deliverables:
➢ 1D unsteady branch flow HEC-RAS model covering entire system, with potential
2D components if created
➢ Hydraulic results for key events to assess existing hydraulic characteristics
➢ Written summary to be included in the Existing Condition Report (Task 11)
➢ Results will be presented during the presentation of the Existing Condition
Assessment (Task 11)
Task 10. Sediment Transpar and Deposition
Task Lead: WSE
Sediment transport and deposition will be evaluated to understand the physical
processes that have caused sediment to deposit within various parts of the system. This
knowledge is critical for developing enduring solutions that will require minimal short
and long-term maintenance. The system is prone to sediment deposition because the
channel slope flattens significantly in the reach between the sediment basin to the
Cedar River. WSE will evaluate existing condition sediment transport and deposition
processes/characteristics by completing three tasks: 1) identifying historical sediment
deposition locations, quantities, and material gradation; 2) field sampling and lab
analysis to determine sediment grain size distribution and characteristics; and 3)
sediment transport and deposition analyses utilizing observed sediment deposition
quantities, grain size data, and the hydraulic model.
Documentation of historical sediment deposition locations and quantities will include
comparison of current and past channel bed elevation data (assuming past channel
surveys and/or channel profiles were surveyed or recorded), review of sediment basin
and channel sediment removal records, and discussions with City and County personnel
involved in channel maintenance. Figures will be created to identify sediment
deposition locations and calculations performed to estimate sediment deposition
quantities.
Field activities will involve the identification and classification of sediment grain sizes
based upon Wolman Pebble counts and laboratory grain-size sieve analyses. WSE
anticipates performing 5 to 8 Wollman Pebble counts and collecting up to 10 bulk
sediment samples for laboratory sieve analyses. Sample locations will be determined
based upon field observations.
Sediment transport and deposition characteristics within the sediment basin and
channel network will be analyzed utilizing the observed sediment data, supported by
hydraulic modeling. The goal is to identify and understand how sediment moves
through the system and to identify what is causing it to deposit at various locations.
The results of the investigation will be summarized and included in the Existing
Condition Report and presented during the Existing Condition presentation.
Assumptions:
➢ City will provide sediment removal dates and quantities if it exists
Anticipated Results:
➢ Figures showing sediment deposition areas and bed level changes
➢ Sediment grainsize distribution curves
➢ Written summary to be included in the Task 11 Existing Condition Report
➢ Results will be presented during the Task 11 Existing Condition presentation
Task r Existing Condition Report and Presentation
Task Lead: WSE
Methods and results of Tasks 1 through 10 will be documented in an Existing Condition
summary report.
Key findings will be presented to the City in a meeting held at City Hall. The consultant
team will also present a range of potential actions to improve the system, actions that
will be identified in Task 12.
Assumptions:
➢ The meeting will last up to 2 hours and will be held at City Hall.
➢ The consultant team will complete Phase 2, Task 12, prior to the meeting so that
a list of possible actions can be presented and discussed. These actions will not
be included in the Existing Condition report, but rather in the Preliminary Design
and Analysis Report (Task 16).
Deliverables:
➢ WSE will provide the draft report to the City as a digital PDF document. If
desired, the text will also be provided as Word file so that the City can provide
comments using the Word track changes feature. Upon receipt of comments,
the consultant will modify the report and submit the final report as digital PDF
file along with one hard copy.
Part 2. Alternatives Analysis and Preliminary Design
Task • .. Identification of Potential Actions
Task Lead: WSE
Using the knowledge gained during the Existing Condition Assessment, the consultant
team will identify potential solutions to reduce flooding and preserve or enhance
habitat. Because the system is so complex and includes many different features, the
preferred alternative will likely consist of multiple individual solutions ("actions") that
each address a specific problem, yet collectively achieve the best project. A preliminary
list of potential actions will be created including simple sketches to illustrate concepts as
needed. These will be presented to and discussed with the City during the meeting in
Task 11. The goal in the meeting will be to seek the City's direction as to which actions
appear feasible and therefore should be carried forward to the next task (Task 13).
The actions presented to the City shall be divided into 2 categories:
➢ Improvements that can be implemented in the short or medium term while
providing some flooding reduction benefits
➢ Improvements to be implemented in the long term that would substantially
reduce or eliminate the risk of flooding, but that would require permitting,
funding and coordination with King County and state agencies.
Assumptions:
➢ The preliminary list of actions will be presented in the form of simple sketches or
descriptions. No detailed design work or technical analyses will occur as part of
this task
Deliverables:
➢ List of potential actions and as needed simple sketches to be presented at the
Task 11 meeting
Task 13. Assessment and r°eenin of Individual Actions
Task Lead: WSE
Based upon the outcome the Task 11 meeting, the consultant team will develop concept
level preliminary designs for 8 to 10 actions. The team will evaluate their likely
performance based on the following criteria:
➢ Flood hazard reduction benefits
➢ Ecological impacts and benefits
➢ Permit acquisition success potential
➢ Mitigation requirements and costs
➢ Capital cost
➢ Maintenance requirements and costs
The consultant team will develop a brief written summary for each action that compares
relative performance based on the six criteria listed above and will use this information
to develop a screening matrix to compare actions. Each action will receive a numerical
score for each evaluation criteria based upon the criteria's perceived importance. The
scores for each action will then be summed to identify the actions that have the
greatest potential for success. Based upon the screening scores, the consultant team
will group the most promising actions into two alternatives to present to the City in Task
14.
Assumptions:
➢ The number of actions to be evaluated will be agreed to by the consultant and
City during the meeting in Task 11. For budgeting purposes, it is assumed that 8
to 10 actions will be developed and evaluated.
Deliverables:
➢ One to two-page summary describing the performance of each action relative to
the six screening criteria
➢ Screening matrix showing the numerical score for each action
➢ Identification of two alternatives to initiate discussions in the next task
Task 14. Meeting with City to Identify a Preferred Alternative
Task Lead: WSE
A two-hour workshop will be held at City offices to review and discuss the actions, the
screening matrix, and the two alternatives. The goal will be to identify a preferred
alternative that includes actions the City feels are best suited to meet the project goals
and objectives. The preferred alternative will then be carried forward to the second
stage of preliminary design (Task 15).
Assumptions:
➢ Two-hour workshop to be held at City Hall
Deliverables:
➢ Presentation materials
Task 15. Preliminary Design of Preferred Alternative
Task Lead: WSE
The consultant team will develop a preliminary design for the preferred alternative. The
team will conduct technical analyses needed to evaluate and refine the design to:
➢ Improve hydraulic and sediment transport performance
➢ Minimize impacts to and/or improve habitat
➢ Minimize need for off-site habitat mitigation
➢ Simplify permit acquisition requirements
➢ Reduce capital costs
➢ Reduce/ minimize maintenance requirements
A planning level preliminary design set will be prepared with sufficient detail to allow
the consultant team to prepare a construction cost estimate that the City can use to
seek grant funding and initiate the permitting process. It is possible that elements of
the preferred alternative will be constructed at different times. The consultant team
will develop the plan set and cost estimate in a manner that will allow the City to seek
funding and implement different elements of the project at different times.
The consultant team will meet with City staff in a two-hour meeting to review the
design, the performance results, and to identify/discuss any refinements that may be
needed. Following this meeting the consultant team will finalize the preliminary design
plan set and cost estimate.
Assumptions:
➢ Two-hour meeting will be held at City Hall
Deliverables:
➢ Planning-level preliminary CAD design plan set
➢ Final planning-level preliminary design plan set
➢ Itemized cost estimate for the preliminary design
Task , Preliminary Design Summary Report
Task Lead: WSE
Approach: WSE team members will prepare a report that documents methods and
results of the Phase 2 investigation and presents the preferred alternative.
Assumptions:
➢ None
Deliverables:
➢ Final CAD files for the preferred alternative
➢ Two-hard copies of the plan set
➢ Itemized cost estimate spreadsheet
➢ Final hydrologic and hydraulic models
➢ WSE will provide the draft report to the City as a digital PDF document. If
desired, the text will also be provided as Word file so that the City can provide
comments using the Word track changes feature. Upon receipt of comments,
the consultant will modify the report and submit the final report as digital PDF
file along with one hard copy.
➢ Any other data generated during the project that the City would like to have for
their records (e.g. GIS files/layers, survey data, etc.)
