SUBJECT:  Salmon Bay Marina Docks D-E Replacement Design  CIP C801070 

Amount of this request:                 $500,000 
Total estimated project cost:          $5,900,000 

ACTION REQUESTED 
Request Commission authorization for the Executive Director  to execute  project design
services, in an amount not to exceed $800,000, including $300,000 previously authorized, in
support of the Port's replacement of the existing Docks D-E at Salmon Bay Marina, including the
associated bulkhead portion and dredging permitted under the existing Master Use Permit. 
EXECUTIVE SUMMARY 
The purchase of the Salmon Bay Marina property by the Port in 2018 included an approved
Master Use Permit (MUP) for new facility in-water and upland improvements as well as a
permit from the U.S. Army Corps of Engineers, and associated regulatory agencies, that allows 
for the dredging required with the replacement of three existing recreational boat docks at the
west end of the marina (refer to accompanying PowerPoint). The Salmon Bay Marina Docks D -E
Replacement project proposes to take advantage of the existing in-water permits before they
expire in February 2020 and replaces the three existing concrete float docks with two new
wider concrete float docks, and associated dredging, to provide improved continued moorage
for recreational boats and bring the float docks up to the Port's service and safety standards.
The proposed work also includes reinforcement of the existing timber bulkhead with new steel
sheet piling, and dredging of the applicable marina area. 
A $5,900,000 placeholder amount for total project costs has been included in the 2019 Capital
Budget and Plan of Finance. This amount is based on a preliminary estimate and will be
finalized in the course of completing the project design which is currently at a 0% stage.

COMMISSION AGENDA  Action Item No. 6k                                   Page 2 of 5 
Meeting Date: January 8, 2019 
JUSTIFICATION 
Under the existing MUP and dredging permits these improvements are required to begin 
construction by February 2020. 
In addition to upgrading facility assets to the Port's standard for service and safety, the
replacement of Docks D-E at Salmon Bay Marina supports the following Maritime Division goals 
toward achieving Century Agenda objectives: 
1.     Continue to grow the economic value of the maritime cluster including the number of
local jobs and business revenue. 
2.     Generate new revenue to support the Port's commitments to stakeholders. 
3.     Prioritize development that maximizes utilization of facility assets. 
4.     Be the greenest, and most energy efficient port in North America. 
Prior to the advertisement for construction bids, the project manager will work with the 
Diversity in Contracting Program team to determine Women & Minority Business Enterprises
(WMBE) participation opportunities in accordance with the terms of Resolution No. 3737. The
requirement for a project labor agreement will be determined as well in coordination with
Labor Relations. 
Staff is recommending moving forward with this project at this time, as the permits would 
expire if we delay.  As we move forward with design, we will be refining costs and looking for
tenants that will use both the uplands and the new docks, and refining revenue projections.
We will return to Commission for construction authorization and will continually review
whether the financial information supports moving forward. 
DETAILS 
The proposed Salmon Bay Marina in-water improvements, permitted under the existing MUP, 
consist of replacing existing concrete float Docks D East, D West, and E with two new 12-feet
wide floating concrete docks (150 lineal feet and one 170 lineal feet in length) secured by steel
piles, accessed via gangways, and equipped with electrical power and water utilities to serve
the needs of recreational vessel customers. The existing float docks, which are secured by a mix 
of piles including creosote treated timber piles, have a limited remaining service life, negligible 
utility services, and pose a safety risk due to their mature condition. Approximately 200 lineal
feet of the existing timber bulkhead will be reinforced with new steel sheet piling installed
behind it as well. 
The permitted dredging consists of a maximum of 11,900 total cubic yards of sediment to be
removed using a barge-mounted clamshell and/or hydraulic dredge in accordance with U.S.
Army Corps of Engineers permitting requirements. The area to be dredged is approximately an
acre in area and the existing current water depth, which varies between approximately 5 and
15 feet, will be increased to a maximum depth of 16 feet beyond the proposed dredge slope

that will extend outwards from the bulkhead.  The existing permit allows for approximately
9,300 cubic yards of sediment to be disposed at a designated open-water Elliott Bay Puget
Sound Dredged Disposal Site, while the remaining estimated quantity of approximately 2,600 
cubic yards of unsuitable material will require disposal of at an appropriate upland facility.
Final suitable and unsuitable sediment quantities and disposal locations are subject to required
approval by the Dredge Material Management Program. All removed sediment is planned to be
transported to the designated disposal site(s) via barge. 
Required project environmental mitigation improvements include a nearshore habitat bench to 
be installed along the bulkhead and topped with a fish-friendly gravel mix, the installation of
shot-rock armoring to ensure stability of a portion of the proposed dredge slope and topped
with mixture of sand and gravel for habitat enhancement, and a total of twelve 35-feet long by
6-feet wide translucent polycarbonate panels to be installed in the metal roofs of the existing
covered moorage (Docks A-C) to allow natural light penetration to the water below. 
Scope of Work 
Facility  improvements  are  anticipated  to  include,  but  are  not  necessarily  limited  to,  the
following: 
1.  Demolition and disposal of existing concrete float docks D-E 
2.  Dredging of applicable marina area up to a 16' maximum depth 
3.  Installation of new steel sheet piling behind existing timber bulkhead 
4.  Installation of new concrete float docks, gangways, and associated utility services 
5.  Implementation of applicable environmental best management practices

Meeting Date: January 8, 2019 
Avoids temporary construction impacts to existing facility customers 

Cons 
Missed opportunity to take advantage of existing in-water permits included in property
purchase. Re -procurement of these permits by the Port will require an estimated five to
six years, substantial additional cost, and the future permit requirements will likely be
more stringent. 
Missed opportunity to replace existing, limited service life, facility assets 
Missed opportunity for improving long-term financial viability of Salmon Bay Marina 
This is not the recommended alternative 
Option Two: Approve SaBM Docks D and E Replacement Design Funds 
Pros 
Takes advantage of existing in-water permits included in property purchase that would
otherwise require five to six years to re-obtain and likely contain more stringent
requirements 
Replaces existing, limited service life, facility assets with new long-term improvements 
meeting Port standards for service and safety 
Creates multiple in-water environmental benefits 
Improves long-term financial viability of Salmon Bay Marina 
Allows us to retain option of using permits as we look for tenant that will utilize both
uplands and new docks 
Cons 
Requires major Port investment of funds 
Creates temporary construction impacts to existing facility customers 
This is the recommended alternative
