ACTION REQUESTED

Request commission authorization for the Executive Director to complete design and permitting

of approximately 830 linear feet of concrete pier apron structure at Terminal 91 including

(1) execute a consultant contract to prepare design and construction bid documents and (2) use

port staff for project management, design support, permitting, and enabling construction

activities, all of which in an amount not to exceed $4,000,000 of a total preliminary estimated

project cost between $35 million and $40 million.

Planned redevelopment would include demolition of approximately 62,250 square feet of

condemned existing timber apron and 830 linear feet of seawall (northerly portion of Berth 6 and

entire Berth 8), removal and relocation of existing gangway, floats and boathouses, removal or

relocation of small office structures, and reconstruction of a concrete apron structure at 600

pounds per square foot along the current alignment. The project assumes no increase in

overwater coverage nor will berth dredging be required to accommodate existing vessel classes.

JUSTIFICATION

The redevelopment of Berths 6 and 8 supports the following Maritime Division goals toward

achieving Century Agenda objectives:

2. Prioritize uses that support the commercial fishing industry, with a focus on anchoring the

3. Supports the Port’s strategy to “be the greenest and most energy-efficient port in North

4. Supports anticipated growth in cruise ship operations.

DETAILS

Berths 6 and 8 are the last remaining original timber pier at Terminal 91 and are at the end of

their service life. Approximately 30% of the apron is condemned, and the remaining sections are

they are replacing. This means vessels that may have previously been able to moor at

Fishermen’s Terminal are now too long or draw too much water to remain and are looking to

moor at Terminal 91. Fishing companies are also growing. As an example, both the Ocean Peace

and O’Hara companies have each added additional vessels to their fleets in the past three years.

Critical to the fleet’s success while in port is access to laydown areas, heavy lift capability pier

side, and ample apron space to perform offloads, backloads, and repair work. This project will

replace approximately 62,250 square feet of condemned existing timber pier structure and 830

linear feet of seawall, providing pier apron capable of supporting the fleet’s activities and needs.

Several times during the shoulder seasons the space at Terminal 91 proves inadequate to

fencing; the relocation of the current port police, construction, and operations office structures

and boat house and floats during construction; demolition of the existing A-310 building; and

construction of a pier structure, fender system, and associated utilities to service fishing vessels

and other customers.

Dredging is not expected to be required to accommodate the current vessel demand; however,

future dredging could be achieved if necessary or desired under a separate project, covered by

responsible materials in the design.

Port staff will also work with terminal users and community groups during the design to mitigate

operational and neighborhood impacts of the construction and keep them apprised of the project

plans. The first briefing to the Neighbors Advisory Committee (NAC) is planned for Q1 2020.

Schedule assumptions below reflect current expected durations for design and permitting;

however, many of these durations are highly variable and controlled by local, state, and federal

agencies, which adds schedule risk to the project. The assumptions below are conservative but

manner similar to past facilities and has used typical sections from these past designs to inform

the estimate.

One significant unknown in this work is the potential impact of updated building codes being

implemented by the Seattle Department of Construction and Inspections (SDCI) planned for June

2020. The change to the 2018 International Building Code will add structural requirements for

sites susceptible to liquefaction (most of our waterfront sites), along with new criteria for

tsunami-resistant design. These new criteria include increased complexity of geotechnical

These requirements are new for both the Port and SDCI, which means there will be uncertainty

ALTERNATIVES AND IMPLICATIONS CONSIDERED

Alternative 1 – Maintain the status quo. Continue to enable limited operations of the berths for

workboat moorage and keep the load restrictions and condemnation of dock sections in place.

Cost Implications: This alternative carries significant uncertainty and risk and accordingly much

variability in cost potential. Maintenance costs for the berth are not currently high but would

expand greatly if a deck failure occurred, for example.

This is not the recommended alternative.

dolphins for example), providing linear moorage without direct apron access by trucks, forklifts,

or other heavy equipment.

Cost Implications: This alternative would cost less than full redevelopment but has many

potential options. A reasonable assumption for the floating dock option might be $15 million-

$20 million or approximately half the cost of the full pier reconstruction, depending on the

amenities provided and capacity of the dock.

Pros:

(1) Lower capital cost.

Pros:

(1) Brings the berth back to full operation, replacing the deteriorated creosote pilings
