EXHIBIT A - SCOPE OF SERVICES
SW 43rd St and Lind Ave SW Storm System Improvement Project - Phase 1
Renton, Washington
November 29, 2023
I. INTRODUCTION
The purpose of this project is to improve stormwater system conveyance capacity on SW 43rd Street
between Lind Ave S and East Valley Road by constructing a new pipeline conveyance system along Lind
Ave SW generally between SW 43rd Street and Springbrook Creek. The project area is shown on
Attachment A.
SW 43rd St has been the location of a reoccurring flooding problem generally between East Valley Road
and Lind Ave S, most notably at the intersection of SW 43rd St and Lind Ave SW. Significant amounts of
standing water in the right-of-way within this area has resulted in the closure of SW 43rd St multiple times
in the between December 2019 and March 2022.
Analysis of the area conducted as part of the Eastside Green River Watershed Plan (EGRWP) in 2007
identified that a new storm system along Lind Avenue SW and SW 39th street with an upgraded outfall to
Springbrook Creek would provide a solution to the flooding issue on SW 43rd Street. Analyses of recent
flooding events by city staff suggests that a combination of factors likely contributes to the flooding issue.
These factors include undersized pipes, insufficient inlet capacity, flow patterns in upstream basin areas,
and high tailwater conditions at the existing pipe system outfall. This project will include assessment of
multiple alternatives to improve flood conditions.
The design effort will be phased. Phase 1 will include field survey; preparation of base map reflecting
survey and all utilities; geotechnical investigations and analysis; hazardous material investigations; review
of existing hydrologic/hydraulic models and reports; use of an update to an existing hydrologic/hydraulic
model for proposed project alternative analysis and design; preliminary environmental evaluations;
preliminary design memorandum that includes an alternatives evaluation and selects the preferred
alternative; and preliminary design (approximately 30%) plans for the recommended solution. The focus
of these investigations will be along the prior alignment defined in the ESGRWP (i.e., between the
intersection of SW 43rd Street and Lind Ave SW, north along Lind Ave SW and then west along SW 39 th
Street to Springbrook Creek), however this alignment will be validated as a part of the Phase 1 work.
Phase 2 of the design effort will include detailed environmental investigation and permits, construction
plans, construction contract specifications, and construction cost estimates.
This contract is for Phase 1 of the scope of work. A preliminary scope of work and budget for Phase 2 has
been submitted separately to the city, however, this is for preliminary planning purposes. The scope of
work and budget for Phase 2 will be refined following the completion of Phase 1.
Existing System Description
SW 43rd Street includes an enclosed pipe system that extends west from East Valley Road to the
intersection with Oakesdale Ave SW. At this location the system is split with most of the flow extending
north to discharge to Springbrook Creek at SW 41st Street in a 54-inch diameter pipe. The other portion
of the system continues west in a 36” diameter pipe to discharge to Springbrook Creek about 1,400 feet
2
west of Oakesdale Ave SW. The main area of flooding is at SW 43rd Street and Lind Ave SW where a
drainage system from the City of Kent flows north consisting of both pipes and open channels. This system
receives runoff from local drainage as well as, overflows from Upper Springbrook Creek where it crosses
SR-167. At the upstream side of SR 167, Upper Springbrook Creek may at time overtop its north bank and
flow north into a wetland along the east side of SR 167. There are several culvert crossings along this
wetland that likely pass flow from the wetland on the east side of SR-167 to a wetland on the west side
of SR-167. The wetland on the west side of SR-167 flows west and north through a system of pipes and
open channels to the intersection of Lind Ave SW and SW 43rd Street. At the downstream side of the Upper
Springbrook crossing of SR-167, a private property owner placed a sandbag coffer dam to prevent high
flow from Upper Springbrook Creek overtopping its bank to flow north into the wetland along the west
side of SR-167 which then drains to the problem area. The extent to which these Upper Springbrook Creek
overbank flows (on both the downstream and upstream side of the SR-167 crossing) contribute to the
flooding issues at SW 43rd St and Lind Ave SW are uncertain and probably variable over time due to
sedimentation occurring within the system.
Along the currently envisioned alignment (i.e., the project area) along Lind Ave SW to SW 39 th Street and
then west to Springbrook Creek, there is a system that begins just north of SW 43rd Street that collects
local drainage and extends north to SW 34th Street and then west along SW 34th Street to discharge at
Springbrook. This drainage system crosses a BNSF local rail line between SW 41st St and SW 39th St. Along
SW 39th St there is a street drainage system beginning a couple hundred feet west of Lind Ave SW that
extends west to Springbrook Creek at an existing outfall that is conveyed within an existing drainage
easement. This system also crosses a local BNSF line.
II. DESIGN CRITERIA
The city will designate the basic premises and criteria for the design. In addition, design reports and plans,
to the extent feasible, shall be developed in accordance with the latest edition of the following
documents:
1. Washington State Department of Transportation/American Public Works Association (WSDOT/
APWA), Standard Specifications for Road, Bridge, and Municipal Construction 2023 edition, or as

Task 5 - Hazardous Materials
The work under this task will be performed by consultant to conduct a hazardous materials environmental
assessment to support the design of a new drainage system for the SW 43rd St and Lind Ave SW Storm
System Improvement Project. The intent of this effort will be to identify and evaluate the project area
(approximately 3,000 ft) for the potential presence of subsurface contaminants that may be encountered
during the project construction. The hazardous Materials assessment for the project corridor will include
the following tasks:
1. Review Environmental Records: Upon notice to proceed, consultant will obtain and review readily
accessible environmental records for the project corridor and adjacent properties. A
subcontracted database service, such as Environmental Data Resources, Inc. (EDR), will be used
to obtain a listing of environmental regulated properties for the project corridor and immediate
vicinity. Available records and databases include Environmental Protection Agency (EPA) listed
and Washington State Department of Ecology (Ecology) listed sites.
2. Review Historical Records: Obtain and review historical aerial photographs, topographic maps,
and Sanborn Fire Insurance maps, as provided by EDR, for the project vicinity.
3. Online File Review: Review technical documents and reports available online from EPA and
Ecology concerning previous environmental investigations for the project site and adjacent
properties.
4. Reconnaissance: Conduct a visual reconnaissance of the project corridor to observe current land
uses and activities pertaining to the potential for subsurface contaminants to adversely impact
the project. Properties being considered for right-of-way acquisition (if any) will be included as
part of the visual reconnaissance. The reconnaissance will be limited to features readily observed
from public access corridors and shall not include entering private properties or viewing
conditions within buildings. The site reconnaissance will include noting the presence and
approximate locations of environmental conditions or associated physical features identified
during the environmental records review.
5. Hazardous Materials Evaluation: Evaluate the resulting data with respect to potential impacts of
subsurface contaminants on development and construction of the corridor project. This might
include identifying areas of potential soil contamination, management and disposal of
contaminated soil, and treatment requirements for dewatering effluent.
6. Draft and Final Hazardous Materials Analysis: Prepare a hazardous materials analysis summarizing
the hazardous materials evaluation. The hazardous materials analysis will be prepared in
9
accordance with the local agency and Washington State Department of Transportation
requirements for a “standard” (i.e., mid-level technical memorandum) to “comprehensive” (i.e.,
full scale report) hazardous materials environmental assessment, whichever is deemed
appropriate. The hazardous materials analysis may include recommendations for any additional
environmental assessment work, potential impacts on property acquisition and construction, and
potential mitigation measures that could be used to minimize contaminant-related impacts.
Assumptions:
1. An environmental hazardous materials analysis is not considered to be a Phase I Environmental
Site Assessment (ESA) that adheres to the American Society for Testing and Materials standards.
If the hazardous materials analysis reveals issues that could impact the project corridor, more
detailed investigations, which may include Phase I ESAs or Phase II ESAs, may be recommended.
If further investigation is recommended, a scope of work and cost estimate will be provided at
that time.
2. The hazardous materials analysis may be presented as part of the State Environmental Policy Act
(SEPA) submittal for the project.
3. Review of Plans and Specifications (in terms of hazardous material considerations) will be in Phase
2 of the project.
4. One round of review of the Hazardous Materials Analysis report will be required.
Task 5 Deliverables
1. Draft and Final Hazardous Materials Analysis
Task 6 - Hydrologic/Hydraulic Modeling of Tributary Drainage Basin
Consultant will use a City-provided model to evaluate the existing system capacities and the proposed
improvements to reduce flooding. This model is a SWMM 5 model developed by Watershed Science &
Engineering (WSE) for the King County Flood Control District (KCFCD). This work will include the following
tasks:
1. Update Existing Model
a. The existing model will be updated to model the Lind Ave system, the SW 43rd Street
system and its two existing outlets to Springbrook Creek. The existing pipe systems will
be based on the existing storm drainage record drawings and project survey. The model
will be extended to include Upper Springbrook Creek and include a representation of the
overflows from Upper Springbrook Creek on both the east and west side of SR-167. This
work will include a site visit by hydraulic modelers to verify model assumptions and
parameters. The system additions south of SW 43rd Street will be based on existing
information on pipe infrastructure from City of Kent/WSDOT as well as Lidar based cross
sections of Upper Springbrook Creek to fill data gaps where previously not surveyed. The
model extends will include the system along Lind Avenue SW north to SW 34th Street and
then west along SW 34th Street to Springbrook Creek, SW 43rd Street west to Oakesdale
Ave SW, with split flow to the west to Springbrook Creek and north along Oakesdale Ave
SW to Springbrook Creek.
10
b. Consultant will review the prior model cross sections along Springbrook Creek for
comparison with updated survey. If needed, cross sections of Springbrook Creek will be
updated in the model. In addition, Consultant will also assess Manning’s roughness
coefficients and update model if warranted.
c. Model Validations and Adjustments. Consultant will simulate up to three recent storms
that resulted in flooding. The intent of this work is to use recent storm observations and
historical precipitation data to validate the model performance. This work will include the
following.
i. Initial runs using existing model that has been extended and updated based upon
existing available data. Initial model runs will simulate identified storm events
that resulted in flooding.
ii. A set of storm simulations using updated Springbrook Creek cross section survey
from Task 3 to assess effects of any historical sediment deposition and or
adjustment of roughness coefficients.
iii. A set of storm simulations using a range of assumed system overflows from Upper
Springbrook Creek (i.e., backing into a range of overflows that would be needed,
if any, to create the observed flooding conditions).
iv. Selection of one recorded storm event as an additional design event to be used
in alternatives analysis along with the city’s standard design events.
v. Prepare a brief modeling validation memo that summarizes the work and
identifies the need for any further survey and/or model adjustments.
d. Run the 2-, 10-, 25-, and 100-yr design storm events under existing conveyance system
geometry and land use conditions. It is assumed that the prior modeling established these
design events. It is also assumed that these storm events are for the previously defined
“Conveyance” storm as defined in the East Side Green River Watershed Plan verses the
“Storage event” (which reflects a large event at the Howard Hanson Dam the required
the Black River Pump Station to curtail pumping rates).
e. Identify flooding locations in the existing system under a range of simulated events.
2. Preliminary Modeling of Alternatives
a. Using the updated Model from Task 6.1, Consultant will evaluate upstream and
downstream flooding reduction benefits resulting from up to 3 proposed alternative pipe
alignments. It is assumed the main pipe alignment of interest is a new system running
north from SW 43rd Street along Lind Avenue SW (leaving the SW 43rd St system in place)
and then west along SW 39th Street to outfall into Springbrook Creek. It is assumed that
it would replace the existing outfall (versus a new outfall, to reduce environmental
concerns and permit implications). Between SW 41st Street and SW 39th Street there is
an existing system that ranges from 48-inch to 54-inch pipe. Within this segment, it will
initially be assumed that the proposed system will be a parallel system to make use of the
existing conveyance capacity. South of SW 41st Street, where the existing system is
smaller diameter (i.e., 15-inch) Consultant will evaluate whether to replace the existing
system or have a parallel system. The above assumptions may be updated as the design
progresses.
11
b. Consultant will determine water surface elevations for the proposed alternative during
recorded flooding events as well as the 2-, 10-, 25-, and 100-year storm events under the
scenario described below.
i. Determine the required pipe size to convey the 25-year and 100-year flows and
the recorded storm event from Lind Avenue SW to the new proposed outfall at
SW 39th Street (assuming backwater elevation) under existing land use.
ii. These pipes will be designed at a minimum in accordance with the criteria
specified in Section 1.2.4 of the SWDM to accommodate a 25-year storm event.
To simplify the modeling of alignments, only key junctions will be included (i.e.,
change in direction or where major trunks connect, and not every manhole).
iii. When sizing, consultant will consider benefits of increasing pipe sizes to build
some conservatism into the analysis as well the benefit of Springbrook Creek
channel maintenance (i.e. vegetation control and/or sediment removal).
iv. Consultant will bracket likely worst-case range of flows that the problem area
could receive from Upper Springbrook Creek system overflows. This could look at
removal of privately installed sandbag dam as well as deposition at the SR-167
culvert that results in significant overbank flows into the wetland along the east
side SR-167. This may also include assumptions about future conveyance
improvements within the city of Kent that could be implemented. The worst-case
assumptions will be discussed with the city of Renton in advance of this work.
v. Consultant will consider changes to hydrology due to climate change and evaluate
the performance of the selected alternative under future flow conditions.
Analysis may include upsizing the system for future performance and resiliency.
vi. Consultant will also review current land use assumptions and assess whether they
are suitable for modeling of future conditions.
vii. Analysis may also include upsizing upstream conveyance elements so that the
model does not contain upstream flooding (which would attenuate flows).
3. Modeling of Recommended Alternative
Following the completion of the Alternative Analysis and Preliminary Design Memorandum (as a
part of Task 9), a model of the recommended alternative will be prepared to support the 30%
design. This model will include the individual manholes and structures along the trunk system.
4. Document the methods, parameters and conclusions, including existing capacity restrictions.
Documentation of the analysis will be incorporated into the preliminary design memorandum.
Task 6 Assumptions
1. Except as noted herein, no other substantive changes, such as redefining sub-catchments or land
use analysis, are anticipated for the existing model provided by the City.
2. The modeling of the system along SW 43rd Street east of Lind Ave SW to of East Valley Road as
well as the system along Lind Ave SW north of SW 39th Street to Springbrook Creek will be based
upon city as-builts (since this system is not surveyed under Phase 1 work).
3. Catch basin inlet analysis, if requested by the city, will be performed under Phase 2.
4. It is understood that Consultant has not had opportunity to review the model (to be provided by
the city but obtained through King County as a part of other planning work in the basin).
12
Consultant has estimated level of effort based on assumptions that the existing model is generally
in reasonable condition in terms of valid model assumptions and its framework set up.
Task 6 Deliverables
1. Brief memo summarizing model input and assumptions for City review.
2. Portions of the Draft and Final Preliminary Design Memorandum described in Task 9 related to
the hydrologic/hydraulic modeling.
Task 7 Critical Area Study
As previously noted, Consultant will complete environmental work for this project in two phases. Phase 1
will focus on determining the existing conditions within the project area. Phase 2 will focus on
environmental reviews and permitting needed to complete the project.
Phase 1 environmental work includes a Critical Areas Study. Consultant (WSP) biologists will conduct a
site visit to assess the project area for the presence of critical areas and formally delineate wetlands and
streams within the project area. If present, wetland and stream boundaries will be:
• Delineated in accordance with the criteria and methods described in the USACE 2010 Regional
Supplement to the USACE Wetland Delineation Manual: Western Mountain, Valleys, and
Coast Region (USACE 2010).
• Ordinary high-water mark (OHWM) on both banks within the project limits will be delineated
in accordance with the Washington State Department of Ecology (Ecology) methodology
found in Determining the Ordinary High-Water Mark on Streams in Washington State (2010).
• Flagged at approximately 30-foot intervals, depending on the complexity of the wetland-
upland boundary, for survey.
• Mapped using sub-meter resource grade GPS equipment.
• WSP will characterize the wetland conditions using the Washington State Wetland Rating
System for Western Washington 2014 Update and associated Rating Forms. Wetland
determination forms and rating forms will be completed for all wetlands delineated.
Consultant will prepare a wetland and stream assessment report to summarize the findings of the wetland
delineation and OHWM determination, including a map of the wetland and stream boundaries. Consultant
will prepare maps for the report using collected GPS data of wetland boundaries, data points and streams.
The report is intended to document existing conditions observed during the fieldwork. A draft wetland
and stream assessment report will be provided to the city for one round of review and comment.
Consultant will provide responses to comments and participate in a comment resolution meeting, if
necessary. Following resolution of comments, WSP will prepare the final wetland and stream assessment
report for the city.
Assumptions
• WSP will delineate up to 2 wetlands within the project area as indicated by a preliminary
review of existing information available on the City COR Map.
• Wetlands outside, but within 300-feet of the project limits will be evaluated using publicly
available information and observations noted during the site visit.
• Formal wetland and stream delineation will occur within the project limits or existing City
right-of-way.
13
• The City will obtain all right of entry within the project corridor prior to any fieldwork. If right
of entry cannot be obtained, WSP will use best professional to assess wetland presence from
areas of public access or City right-of-way.
• WSP will provide two wetland biologists to conduct the site visit. Delineation of the wetlands
and OHWM can be completed within one 10-hour day, including roundtrip travel.
• Consultant will provide formal survey of delineated wetlands and flagged OHWM boundaries.
• The wetland and stream report will be prepared to meet the requirements of the City of
Renton Critical Area Ordinance.
• The wetland report will only document existing conditions at this time. WSP will not prepare
any impact analysis to wetlands, streams, or their respective buffers in this Phase.
• There will be one round of City review on the draft wetland report.
• Permit applications are not included in this Phase.
Deliverable
• Draft and final wetland and stream assessment report, including datasheets and rating forms.
Task 8 Cultural Resources
The project is anticipated to require a permit from the U.S. Army Corps of Engineers and is therefore
defined as a federal undertaking by the National Historic Preservation Act (NHPA) and the project must
comply with Section 106 of the NHPA and its implementing regulations (36CFR800).
Task 8.1 Coordination and Project Management
Consultant (ESA) will maintain regular communication with the project Consulting team regarding
progress, budget, and schedule, and coordinate with the necessary agencies and contractors. This task
includes time for client and internal team meetings. Consultant (ESA) will provide monthly progress
reports and invoices and for the duration of the tasks.
Task 8.2 – Archival Literature Review and Field Visit
Consultant (ESA) will conduct archival research at the Washington State Department of Archaeology and
Historic Preservation (DAHP), relevant libraries, within its own research library, and online repositories to
identify recorded and potential cultural resources in the project’s study area. Consultant will also review
project-specific environmental and geological background information developed during the project by
other team members.
Consultant will conduct a pedestrian survey of the project area to confirm the assumption that the entire
project area is covered by impervious surfaces or appears to be previously disturbed by installation of
utilities and roadways. Consultant will photograph and document the project area.
If requested by the city, Consultant will solicit Tribal technical information to be included in the Technical
Report. The letter will include project description, the proposed APE, and Consultant’s recommendation
for further cultural resource study.
Deliverables:
• Email soliciting Tribal technical information. ESA will contact the Suquamish Tribe,
Snoqualmie Indian Tribe, Muckleshoot Indian Tribe, Tulalip Tribes, and the Squaxin Island
Tribe.
• Information gathered during this task will be included in the Technical Report (Task 8.3).
14
Task 8.3 – Technical Report
Consultant (ESA) will summarize the findings and recommendations from Task 8.2 in a Technical Report.
The report will meet the DAHP standards for a cultural resources assessment (April 2023).
Deliverables:
• One Draft Report (Word format) for review by WSP and city.
• One Final Report (PDF format) for WSP and city.
• If DAHP requires revisions to the report, ESA will prepare up to one Revised Final Report (PDF
format) and one revised site form update for re-submittal to DAHP under the direction of
AGENCY.
Assumptions:
• The project is anticipated to last up to 18 months from Notice to Proceed to closeout.
• The Study Area will be 1-mile radius of the project footprint for archaeological resources. For
aboveground historic resources (buildings, structures, and objects), the Study Area will
include the project area and the immediately adjacent parcels.
• WSP will provide ESA with copies of any regulatory correspondence regarding project
requirements or review.
• Because the project area is completely paved or covered with impervious surfaces, subsurface
archaeological survey will not be required by agencies.
• Because the project will not result in permanent aboveground changes, ESA assumes that a
historic resources inventory will not be required by agencies.
• ESA will open the project in DAHP’s WISAARD system and upload the final report for submittal
to DAHP, under direction of the city.
• ESA assumes that no historic property inventory will be needed to complete Phase 1 of the
Project Schedule
Task 9 - Alternatives Analysis and Preliminary Design Memorandum
This task builds on the existing information developed about the project area to assess various alternatives
that may be considered for the project improvements. The alternatives that may be considered could
include the following:
x Consideration of alternative alignments along the planned corridor (Lind Ave SW and SW 39th St)
to best work with traffic, utility conflicts, and other considerations.
x Consideration of alternative alignments. A brief investigation will be done to look at an alternative
alignment of Lind Ave SW to SW 34th Street and then west on SW 34th Street to Springbrook
Creek, and an alternative alignment of SW 43rd St west to Oakesdale Ave SW and then north on
Oakesdale Ave SW to Springbrook Creek. Note that since survey and geotechnical information will
not be done along this full alignment length, the alternative comparison will be limited. Should
this alignment be worth further investigation, a scope adjustment will be needed.
x Consideration of additional pipe system improvements along SW 43 rd Street between Lind Ave
SW and East Valley Road (EVR). Note that this may be more limited evaluation because it is not
surveyed under Phase 1, in part because it is unknown if conveyance improvements are needed
in conjunction with the new system along Lind Ave SW.
15
x Consideration of what assumptions should be made on upstream flow contributions from the City
of Kent (i.e., Upper Springbrook Creek system overflow) and effects on conveyance sizing. This
assessment will incorporate observations made from the site visit (Task 2), input from
Stakeholders (Task 10) as well as well has hydrologic/hydraulic modeling (Task 6). The intent is to
bracket the range of flows that could be contributing to the flooding problem, and its effect on
alternative sizing (if its affect changes pipe sizing) and what it may mean in terms of costs,
constructability, and other advantages and disadvantages.
Alternatives Analysis and Preliminary Design Memorandum: Up to three alternatives will be defined and
evaluated. These alternatives will include a mix and match of the above considerations. Consultant will
work with city to define the three alternatives prior to completing the evaluation. A concept figure will be
developed for each. The alternative will be compared on the basis of cost, performance, constructability,
permitting implications and other advantages and disadvantages. Additional factors to be considered
(likely within the advantages and disadvantages discussion), include geotechnical considerations, traffic
impacts, access, dewatering, property impacts, utility conflicts, utility relocation, roadway restoration,
and acquisition needs, and potential maintenance considerations. The analysis will consider potential
conflicts with utilities, alignment alternatives and pipe configurations, construction methods and
construction phasing and sequencing to minimize cost and traffic impacts. The results of this alternatives
analysis will be summarized in a Preliminary Design Memorandum which will summarize the evaluation
in an alternatives analysis matrix and recommend a preferred solution. This memorandum will also
include a summary of the basis for design of the recommended alternative.
Final Preliminary Design Memorandum and 30 Percent Design Drawings: Following city review of the draft
Preliminary Design Memorandum, consultant will finalize the Preliminary Design Memorandum to
incorporate city comments and also prepare and include 30 percent design drawings for the preferred
alternative. The Final Preliminary Design Memorandum will include the design criteria, alignment, layouts
and identifying problems, conflicts, and mitigation measures. For the 30 percent design and added section
of the memo will discuss conflicts with utilities, alignment alternatives, pipe materials, construction
methods and construction phasing and sequencing to minimize cost and traffic impacts. There are 23
anticipated drawings for the 30% design to include the following:
1. Title sheet, location map, and index of drawings.
2. Legend and Abbreviations
3. Key Map
4. Existing utilities data (pothole schedule)
5. Plan and profile sheets, 11 sheets (Scale of 1” = 20’ at full size 22”x34”) (based on 4,200 feet
project length and 400 feet per sheet)
6. Preliminary Details (assuming 1 sheet of key details)
7. Plan/profile sheets for key utility relocations (3 sheets)
Task 9 Assumptions
1. While the portion of SW 43rd St from Lind Ave SW to EVR will be analyzed and discussed in the
report in terms of recommendations, this area will not have been surveyed and will not be
included in the 30% design drawings.
16
2. Restored or replaced roadway, sidewalks, ramps, and driveways are assumed to be restored to
meet current City/ADA standards (note however, the roadway restoration plans will be completed
in Phase 2).
3. Restoration Plans and Temporary Erosion and Sediment Control (TESC) Plans will not be
developed under the Phase 1 scope.
4. Utility relocation design for franchise utilities is included in final design.
5. Revisions to 30% design based upon city reviews will be completed under the Phase 2 scope of
work.
6. Traffic control for the intersection of SW 43rd Street and Lind Ave SW will be discussed in the
report; however, no plans will be included in this phase.
Task 9 Deliverables
1. Draft and Final Preliminary Design Memorandum; Final memorandum to include 30 percent
design drawings for preferred alternative.
2. 30% design cost estimate
3. Phase 2 Work Plan and Schedule
Task 10 – Phase 1 Stakeholder Coordination
