for design, project management and permitting of the upgraded fender system on Pier 91
at Terminal 91 in the amount of $625,000; 2) Construction of initial work to address
current operational concerns at the end of this cruise season for up to $500,000; and
3) Pre-purchase of materials for initial construction and purchase of camel barges to be
used starting with the 2011 cruise season at a cost not to exceed $1,000,000. The total
amount of this request is $2,125,000, and the total estimated project cost is $5,700,000. 
SYNOPSIS:
The business activity generated at Terminal 91 from the fishing and cruise industries is a
significant source of maritime employment and state and local tax revenue. However,
replacement of the current fender system at Pier 91 (P91) is necessary to continue
operations in this area. This replacement/upgrade will allow the Port to meet obligations
of current lease agreements, long term preferential berthing agreement with cruise lines,
arrange annual preferential berthing agreements and increase utilization of this multi-use
facility. It will also improve water quality by removing ACZA-treated timber piles from
the marine environment and replacing them with non-reactive steel piles.

The current fender systems at P91 are a mix of steel and wood timber designs. Although
this pier has served a variety of large commercial vessels for many years, the fender pile
system on the outer face which protects the concrete dock structure was not originally
designed for docking cruise ships. The current fender design on P91 is very similar to the
fender system which formerly served cruise vessels at Terminal 30 (T-30). To complete
the fender system set-up during cruise operations, floating steel breasting barges are
positioned between the cruise ship and fender piles. These are necessary to hold the
cruise ship off the dock, a safe workable distance, to allow access into the lower ship
holds throughout tide cycles for luggage handling and ship provisioning.
During the five years of cruise terminal operations at T-30, several wooden timber piles 
were broken as a result of cruise vessel docking. Consistent with the performance of the
T-30 timber fender pile, the east cruise berth at P91 which also has timber fenders has
experienced several broken piles since opening the new facility in 2009. The timber
fender piles on the east berth of P91 and the steel breasting barges which were relocated
from T-30 are reaching the end of their usable life and need to be upgraded. The existing
steel fender piles on the west berth of P91 appear to be working fine for cruise operations
and are showing no signs of failure. 
The Capital Development Division requests approval to design and permit a new fender
system to replace the failing systems on Pier 91 which will be designed to serve all
cruise, fishing and industrial vessel moorage into the future; and also to address
immediate operational concerns for continued cruise vessel docking on the east berth in
the first phase of construction to be complete before the 2010 cruise season. 
ADDITIONAL BACKGROUND: 
The former cruise berths located at the T-30 Cruise Facility were moved to Terminal 91
as part of the Terminal 30 Cargo Reactivation and Cruise Relocation to Pier 91 project.
The new Smith Cove Cruise Terminal at Terminal 91 was opened in April 2009.
Engineering analysis done prior to opening the new cruise terminal indicated that the Port 
would need to upgrade the existing fender system serving the cruise berth at some point 
in the future. Prior to constructing the new cruise facility on P91, it was determined that
the current fender systems would be adequate for opening the facility and berthing the
cruise vessels scheduled for the new terminal in 2009 with the understanding that the Port
would closely monitor the performance of fender piles on P91 and the used breasting
barges throughout the initial cruise season. 
Several failures of the timber piles occurred on the east berth last year causing the need
for a critical work authorization in August 2009 to replace specific areas of fender piling.
Continued close monitoring of the fender system this year has identified additional failure
of the timber fender pile in other areas of the east berth.

PROJECT DESCRIPTION AND JUSTIFICATION: 
Design, Project Management and Permitting 
The current fender system at Pier 91 consists of steel and timber fender piles consistently
spaced around the entire finger pier. 
The current timber system on the east side of the pier was built in 1997, and although
suited for large commercial vessels, the system was not designed for use by cruise
vessels. 
The current steel system on the west side of the pier was built in 2005, and while it was
not explicitly designed for cruise vessels, it is not expected to need full replacement as
part of this project. The design will include a full evaluation of the current system and
any modifications required. 
The east and west berths currently service fishing and industrial customers, and cruise
vessels from April to October of each year. During cruise season, floating steel camel
barges are secured to the pier which holds the cruise vessel a distance away from the
dock necessary to provide space between the dock and the ship for loading and unloading
luggage and ship provisioning. 
Phase 1 Construction 
While the existing steel fender system on the west side has been performing well; there
have been a significant number of timber piles on the east that have broken. In August
2009, Port crews installed 16 temporary steel piles to supplement the existing system on
the east berth necessary to complete the cruise season. While these temporary steel piles
have been performing well, there have been additional timber piles that have broken this
season. 
To address this immediate concern, staff propose installing the first 10-20 steel piles to
address these weakened areas in advance of the full replacement of the east side timber
system. This would be accomplished using a small works contract to remove and drive
the piles, and Port crews to tie the new piles into the existing structure similar to the
method used for the previous critical work. However, these piles would be incorporated
into the permanent fender system. In order to avoid continued breakdown of the system
and to prevent interruption of the cruise operations, these upgrades are necessary. 
Addressing the issue this way allows for a timely solution to the immediate concern,
while allowing the full design and permitting to continue at the same time.

Pre-purchase of phase 1 materials and replacement camel barges 
To support the initial phase of work the long lead items such as steel piles and HDPE
facing will need to be pre-purchased. Also the project includes the replacement of the
existing steel camel barges with upgraded camel barges. As these offer superior
performance to the current barges and could be used with the existing systems, staff is 
requesting authorization to purchase the new camel barges to be placed in service starting
with the 2011 cruise season. 
PROJECT STATEMENT AND OBJECTIVES: 
Project Statement: 
Upgrade the existing fender systems at Pier 91 to provide a continuous steel fender
system with adequate capacity to service industrial, fishing and cruise customers. 
Project Objectives: 
Adequately protect the pier structure during all types of vessel berthing and provide safe
and secure moorage for all vessel operations. 
PROJECT SCOPE OF WORK AND SCHEDULE: 
Overall project scope would include fender upgrade of each 1,200 foot cruise berth
including the replacement of the old and deteriorated fender pile system with a new steel
fender system, replacement of the camel barge equipment, and evaluation of the existing
steel fender system to ensure capacity for all users of the facility. 
Design and permitting scope under this authorization is to include preparation of plans,
specifications and estimates for completing this work, submission of all applicable permit 
applications required for in-water work to construct the new facilities, separate permit for
construction of the first phase of work, and pre-purchase of long lead items and
replacement camel barges. Staff will return to Commission to request approval to
advertise remaining Phase 2 work once design is complete.

Key risk factors                 Key risk factors include permitting delays and potential cost
overruns due to project complexity/timeframe. 
Project schedule could be delayed due to project complexity,
permitting delays, in-water work constraints, and the need to
minimize disruptions to terminal operations and existing
tenant/customers. This risk is partially mitigated by a
phased construction approach. 
Procurement of steel piles and other construction materials
are long lead items. Delays in material delivery may
adversely impact planned construction timing. 
Project cost for analysis        $5,700,000 (preliminary cost estimate) 
Business Unit (BU)            Cruise Operations 
Effect on business              Fender system replacement will preserve existing revenue
performance                    from Terminal 91 cruise operations. 
At completion, incremental depreciation expense from the
steel fender system replacement project is estimated at
$285,000/year, based on a 20 year asset life. 
IRR/NPV                  No incremental revenue. NPV is present value of project cost.

(in $000's)
ECONOMIC IMPACTS AND BUSINESS PLAN OBJECTIVES: 
Replacement of this essential protective system will allow continued operation of
industrial, fishing and cruise industry activity in this area. This replacement will allow the
Port to meet obligations of current lease agreements, long term preferential berthing
agreement with cruise lines, arrange annual preferential berthing agreements with fish
trawler fleet and achieve our objective to increase utilization of this multi-use facility. 
Based on business activity data collected in 2007 and 2008 at Terminal 91, Fisherman's
Terminal and the Maritime Industrial Center, it was estimated that commercial fishing
activity generated $814,400,000 in business revenue; 5,607 direct jobs; 8,028 induced
jobs; 1,337 indirect jobs; and $167,600,000 in state and local taxes. 
In 2010 the cruise industry will bring an estimated $425,000,000 in annual business
revenue; 4,447 jobs and $18,900,000 in state and local taxes to our region. 
STRATEGIC OBJECTIVES 
This project supports the Port's strategies to "Ensure Airport and Seaport Vitality" and
"Exhibit Environmental Stewardship through our Actions", by:

Replacing the fender system at the subject Terminal so that the Terminal can continue
servicing cruise, fishing and industrial customers. 
Improving water quality by removing ACZA treated timber piles from the marine
environment. 
Replacement of the fender system in this area is a renewal and replacement project
for the Seaport. It will help protect revenue the Port currently receives and meet its
lease and contractual obligations. 
Meet Environmental Obligations 
The project will meet environmental obligations by removing treated timber fenders. In
addition the project will: 
Acquire all necessary and required permits from appropriate agencies prior to start of
construction;
Comply with all conditions stipulated by permit authorizations; 
Use best management practices to reduce water quality impacts during construction,
and; 
Use vibratory pile driving techniques to reduce noise impacts to endanger species. 
Develop and Maintain Community Support 
This project will develop and maintain industry support by retaining longstanding
tenant/customers in our harbor, with their related employment and the necessary purchase
of goods and services to service, maintain, repair and upgrade the vessels while at port. In
addition, the permit process requires notification of neighboring communities, agencies
of interest and appropriate environmental groups. Comment is expected and welcome. 
ALTERNATIVES CONSIDERED AND THEIR IMPLICATIONS: 
Alternative 1: Wait for full design and permitting before starting any work. This
alternative carries a high risk of further failures and loss of berthing capability. This
alternative is not recommended. 
Alternative 2: Install further temporary piles to address the short term risk. Piles would
need to be removed prior to permanent solution. This alternative is not recommended. 
Alternative 3: Install the entire system immediately. This alternative presents significant
challenges in design and permitting schedule, including need to place piles outside of the
accepted environmental permit window, which may not be approved by permitting
agencies. This alternative is not recommended.

COMMISSION AGENDA 
Tay Yoshitani, Chief Executive Officer

Alternative 4: Proceed with an initial phase of construction, complete the full design
and apply for permits. This provides protection for the short term, and allows this
fix to be incorporated in the final system. This is the recommended alternative.
