INFORMATIONAL MEMORANDUM
Mayor Haggerton
Utilities Committee
FROM: Bob Giberson, Public Works Director
By: Ryan Larson, Senior Program Manager
DATE: July 18, 2014
SUBJECT: East Marginal Way S Stormwater Outfalls
Project No. 91041204, Contact No. 14 -010
Supplemental Agreement No. 1
ISSUE
Approve Supplemental Agreement No. 1 to Contact No. 14 -010 with KPG, Inc. (KPG) to produce 90% plans, specifications,
and cost estimate for the East Marginal Way S (EMWS) Stormwater Outfalls project.
BACKGROUND
Drainage along the northern portion of EMWS is conveyed to the Duwamish River through four separate outfalls. The outfalls
are owned by Jorgensen Forge, The Boeing Company (Boeing), and two by the King County International Airport. The
Jorgensen Forge outfall was abandoned in 2012 under an order from the Environmental Protection Agency (EPA) and flows
have been temporally diverted to a King County Airport outfall. Boeing is currently in final negotiations with the City to transfer
ownership of their outfall.
KPG was contracted for the design report through Contract No. 14 -010. The City received a 2013 -15 Department of Ecology
(DOE) Municipal Stormwater Capacity grant for the EMWS Stormwater Outfalls project. The grant requires that the project
incorporate Low Impact Development (LID) water quality measures within the outfall basins.
ANALYSIS
The City submitted the required design report to the WA State DOE for review. The DOE is requiring that additional analysis
be done to demonstrate that the planned permeable pavement LID technique proposed in the Design Report is appropriate at
this location due to the areas designation as a Superfund Site. Supplement No. 1 will address the DOE's concerns and take
the design to the 90% level. Completion of final design will be done once additional design and construction funding is
secured.
BUDGET SUMMARY
This project will be funded through the 412 Surface Water Fund using WA State DOE grant funds. In addition to the DOE
Municipal Stormwater grant, the City also received $50,000 in a DOE Watershed Grant. It is proposed that $20,000 from the
DOE Watershed grant be used to fund this design effort.

East Marginal Way South
Stormwater Outfalls Project
Supplement No. 1
Prepare 90% Design
Scope of Work
July 15, 2014
Drainage from East Marginal Way South historically discharged through outfalls owned
and operated by the Boeing Company, Jorgensen Forge, and two King County Airport
storm systems. The Jorgensen Forge outfall was abandoned in 2012 under orders
from the Department of Ecology (DOE) due to contaminants within the conveyance
pipe and this East Marginal Way South discharge has been temporarily diverted to the
King County Airport outfall.
Grant funds may be available from DOE through the 2013 -15 Municipal Stormwater
Capacity Grant Program for permanent outfall modifications. In order to be eligible for
this grant program, the project must incorporate Low Impact Development (LID) water
quality measures to the extent feasible within the outfall basin. An analysis for a
permanent conveyance solution was completed by GHD Consultants in September
2011. This analysis provided conveyance options for the abandoned Jorgensen
Outfall, but did not consider water quality retrofit as required by the current DOE grant
program. The grant program requires all participants to submit a pre- design report to
determine grant eligibility.
Under the original contract authorization, KPG prepared a pre- design report in the
format required for the 2013 -15 Municipal Stormwater Capacity Grant Program based
on previous conveyance analysis and findings of water quality analysis. Maps and
layouts for the pre- design report will be based on aerial mapping, GIS data, and
available as -built data.
DOE has provided comments to this report and determined that the project remains
eligible for design grant funds. This supplement is provided to complete survey,
environmental documentation, geotechnical analysis, and 90% design in accordance
with the attached scope of work and grant funding requirements.

TASK 1 — MANAGEMENT / COORDINATION / ADMINISTRATION
1.1 The Consultant will provide continuous project management for the project duration (8
months).
1.2 The Consultant shall prepare monthly progress reports identifying work in progress,
upcoming work elements, and reporting of any delays, problems, or additional
information needs. The monthly progress reports shall be submitted with invoices.
Task 1 Deliverables:
• Monthly progress reports (8 months).
TASK 2 — SURVEY AND BASE MAPPING
2.1 The Consultant shall perform field surveys and prepare base maps within the project
limits and prepare 1" = 20' detailed topographic base maps of each street corridor.
2.2 The Consultant shall field verify the base map for accuracy.
2.3 The Consultant shall coordinate field utility locates for underground utilities, by
subcontracting with a reputable locate firm to paint horizontal utility locations prior to
topographic survey updates for inclusion on the project base maps.
2.4 Research available public records and perform field ties to show existing right of way
on the project base maps.
Task 2 Deliverables:
• Electronic Base Map showing utility locations, surface features, contours, and existing
right -of -way.
Task 2 Assumptions:
• Basemap will be prepared in AutoCAD Civil 3D 2013 using KPG drafting standards
• Right -of -way Plans, legal descriptions, or acquisition will not be required.
• Potholing, if required, will be provided by private utility owners.
TASK 3 — GEOTECHNICAL EXPLORATION
3.1 GEOTECHNICAL SERVICES: Geotechnical services will support design and
construction of the new storm drain and will be performed by GeoDesign under
subcontract to the Consultant. The purpose of these services will be to explore
subsurface conditions at the proposed locations of the improvements and provide
integrated geotechnical and environmental services to support design of the planned

22
improvements. The specific scope of services will include:
• Review of the pre- design plans and existing geotechnical and environmental
information.
• Attend a kick -off meeting with the project team.
• Plan and perform a subsurface investigation that includes:
• Complete a traffic control plan for the proposed work and obtain
appropriate right -of- way (ROW) permits.
• Identify and mark boring locations based on proposed improvements and
existing utility information. During Phase I of the project for the pavement
rehabilitation along East Marginal Way we encountered numerous utility
conflicts that created challenges with completing borings along the roadway.
Separate site visits will be necessary to locate the borings and complete the
utility locate services and then review locates to verify the proposed locations
are clear of utilities.
• Complete up to 6 subsurface borings to the base of the proposed pavement
section or bioretention cell and complete in situ infiltration tests. Borings will
be completed to a depth of 15 feet BGS or groundwater, whichever is less, to
explore conditions below the base of each facility. Soil samples will be
collected at 2.5 -foot intervals to the bottom of each boring. Samples will be
screened for potential volatile organic compounds with a photoionization
detector. Environmental samples will be collected of material suspect of
contamination.
• Complete in situ falling head tests in each boring to obtain an estimate of the
short -term infiltration rate.
• Maintain a detailed log of the explorations, and obtain samples of soil
encountered.
• Perform geotechnical laboratory testing that includes 3 grain -size determinations
and 3 grain -size determinations with hydrometer tests, up to 7 moisture content
determinations, and 6 cation exchange capacity and organic content tests for
evaluation of soil water quality treatment capacity.
• Perform analytical testing to screen samples suspect of being impacted by
contaminants. Required tests will vary depending on the type of contamination
suspected. We have provided an analytical testing allowance for the tests.
• Provide a draft report that summarizes the results of our investigation and our
conclusions and recommendations regarding the following:
• Subsurface conditions
• Results of environmental screening and analytical testing
• Results of in situ infiltration tests and geotechnical laboratory tests
• Estimated long -term infiltration rates based on our experience, results of in
situ testing, and laboratory testing
• Impacts associated with stormwater infiltration
• Subgrade preparation and fill materials for construction.
• Attend a post draft report meeting to discuss findings and conclusions.
• Prepare a final report that incorporates design team comments on the draft report.
