ACTION REQUESTED 
Request Commission authorization for the Chief Executive Officer to complete the design,
purchase materials and proceed with construction by Port Crews of the T-91 Lighting Upgrades
project, for a total cost of $1,035,000. This request seeks a single Commission authorization to
combine design, materials purchase, and construction. 
SYNOPSIS 
The purpose of this project is to reduce energy usage while providing improved lighting at
facilities and parking for Piers 90 and 91 at Terminal 91. Existing exterior lighting for Piers 90,
91 and Cruise Parking is inefficient and has surpassed its useful life span. Lighting requirements
for work areas have changed over the years, requiring improved lighting for activities in marine
loading and unloading areas. The Port currently provides area lighting to its tenants and
customers without the ability to vary light levels based on lighting needs. Conversion of
inefficient High Pressure Sodium fixtures to more efficient Light Emitting Diode (LED) fixtures
and installing lighting controls will reduce electrical energy usage by more than 75%, reduce
GHG emissions, reduce light spillage and glare to surrounding neighborhood and provide a safe,
well lit working environment. Seattle City Light will pay an estimated $200,000 toward the cost
of this project as incentives to implement energy efficient modifications. 
Installation of lighting fixtures is anticipated to begin in January 2014 and be completed in April
2014. Commissioning will take place immediately following installation and is expected to be
complete in May 2014. The schedule is dependent on material lead times, weather, crew
availability  and terminal operations schedules.  Combination of authorization for design,

materials purchase, and construction is requested because the design and construction portions
are small in comparison to the materials purchase. 
BACKGROUND 
Pier and parking lighting for both Pier 90 and Pier 91 is provided by high mast lighting atop 65-
foot poles. The high mast poles and fixtures were originally installed in the 1970s and most have
only received minor upgrades and improvements. The existing lighting consists primarily of 381
1000W High Pressure Sodium (HPS) lighting arranged in four, six and eight fixture arrays.
Existing lamps requires re-lamping at 3-7 year intervals for all 381 of the existing area lighting
fixtures. Many of the existing fixtures are old and in poor condition due to the corrosive
environment. Port maintenance estimated $185,000 of needed maintenance to sustain operation
of the existing area lighting in 2014. Ongoing maintenance for the next five years is expected to
cost an additional $145,000 and will cost over $260,000 for years 6-10. 
Existing exterior lighting for Piers 90, 91 and Cruise Parking consumes approximately 950,000
kWh of energy per year, costing the Port in 2013 about $57,000 in electricity fees. Replacement
of existing fixtures with high efficiency LED lighting coupled with operational changes to
lighting patterns will reduce energy consumption by up to 76% based on calculations using
Seattle City Light Energy Conservation tools.  This maximum reduction translates into an
electricity cost reduction of approximately $42,000 per year. Over the ten-year lifespan of the
LED fixtures, inflation-adjusted electricity costs total approximately $237,300 compared to the
inflation adjusted electricity cost of over $806,500 without modernizing current lighting systems.
Electrical costs alone will be reduced nearly $569,206 over the ten-year lifespan of the fixtures.
Reducing electrical consumption also has a net effect of reducing 3,759 tons of greenhouse gas
emissions (GHGs) over the ten-year lifespan due to reduced electrical generation needs.

LED lighting has many advantages over High Pressure Sodium lighting. LED lighting delivers
white light, which is a full-spectrum light (see examples in Attachment-C) and can be directed to
areas where the light is needed. Unlike HPS lighting, which is a yellow light, LED lighting
enables users to differentiate colors that are not clearly identifiable under HPS lighting. Safety
features such as pavement markings, cautionary signage, and other features become more legible
under LED lighting. LED lighting can be dimmed, turned off and instantly turned back on to
respond to needs. HPS requires up to 30 minutes to come back on; for this reason, once existing
fixtures have been turned on, they tend to be left on all night. HPS typically has a life span of

15,000-25,000 hours depending on lamp and ballast quality. Current LED lighting is rated at
50,000-60,000 hours (11-13 years). 
The project also plans to install modern lighting controls to manage lighting from a central
location.  Modern controls provide accurate energy use monitoring and can provide reliable
reports to determine lighting energy usage. When the piers and other operating areas or portions
of the piers are unoccupied, the lights will automatically dim to a security level. In unoccupied
mode, the lights will also respond to occasional occupants (a person leaving a vessel for
example) by sensing movement and elevating light levels for safety. Also, in an emergency
situation, the Port can respond by instantly lighting the entire property or specific portions. 
Engineering design for the project is minimal. Berger ABAM / Wood Harbinger (Electrical
Engineering) is working through the Port's Infrastructure IDIQ Contract to performpreliminary
design, provide lighting fixture and control specifications, and estimate costs for the project. The
consultant will provide product specifications and wiring diagrams. Material costs make up the
predominant cost of the project and will be competitively bid. Installation will be performed by
Port Crews to allow continuity of Terminal operations. Wood Harbinger will provide bid
documents and support through installation. They will oversee commissioning with the Controls
Contractor, Port Electricians, and a Seattle City Light Energy Conservation Official. 
PROJECT JUSTIFICATION AND DETAILS 
The Terminal 91 Lighting Upgrade project will reduce electricity usage by approximately
$42,000 per year, reduce maintenance costs, reduce GHG emissions by over 400 tons per year,
allow accurate monitoring of energy use, provide improved lighting illumination levels and
quality of light in the loading/unloading areas of Piers 90 and 91 and the cruise parking area. 
Project Objectives 
Improve lighting performance: Improve lighting illumination levels to provide a safer,
more effective workplace for pier activities and visitors to the Port. Improve security
through enhanced visibility on the piers. 
Energy Efficiency: Reduce terminal outdoor lighting electrical energy usage by 76%. 
Carbon Reduction: Avoid greenhouse gas emissions from deferred energy generation
Controllability: Lighting controls will enable the Port to deliver light as is needed and
accurately monitor and measure energy used. 
Reduce light and glare: Fixtures will be shielded to conserve night sky darkness and
reduce light and glare spillage to neighborhoods. 
Reduce Maintenance Costs: Fixture maintenance and replacement at Piers 90, 91 and
the cruise parking will be reduced from approximately $592,000 to $110,000 for LED
lighting over the next ten years. 
Economic Responsibility: Total cost of ownership of lighting systems replaced meets a
financial objective of simple payback in approximately eight years. Seattle City Light
Energy Conservation Resources will provide rebates to the Port for a portion of the cost
associated with this project. Seattle City Light will pay an estimated $200,000 toward
the cost of this project as incentives to implement energy efficient modifications.

Inclusion of controls with "Revenue Grade Energy Metering" will enable the Port to
accurately calculate the cost for lighting use. 
Compliance: Installed lighting will comply with federal OSHA, Washington State
Labor and Industry standards, Coast Guard and other applicable regulations and
standards. LED lighting will enhance the capability of existing security cameras
through delivery of full spectrum light evenly distributed throughout. 
Sustainability: Modern LED fixtures are expected to have a life span of 10-13 years 
versus 3-5 year replacement for existing lamps. Controls will enable the Port to limit
lighting to the hours and levels required by the users resulting in extended fixture life.
Replacement lights will be rated for marine environment and include bird deterrents to
avoid buildup of corrosive materials.

Budget Status and Source of Funds 
Initial project design, preliminary energy audit, acquisition planning and project initiation and
management was funded from Seaport expense funds for $90,000 to determine feasibility of
project before requesting Commission action. This project was included in the 2013 Plan of
Finance as a Green Initiative Project under CIP C800160 for $835,000. While the gross project
cost is $1,035,000, the Port is expected to receive $200,000 from Seattle City Light's energy
incentive fund as a rebate, which brings the net cost to the Port to $835,000. The project will be
funded by the general fund.

STRATEGIES AND OBJECTIVES 
This project aligns with the Port's commitment to be the nation's leading green and energy-
efficient port. Upon completion, The Terminal 91 Lighting Upgrade project will reduce
electricity usage by 721,435 kw/hrs per year translating to an operation cost savings of
approximately $42,000 per year, reduce maintenance costs, reduce GHG emissions by over 400
tons per year, allow accurate monitoring of energy use, provide improved lighting illumination
levels and quality of light in the loading/unloading areas of Piers 90 and 91 and the cruise
parking area.
TRIPLE BOTTOM LINE 
Economic Development 
This project provides necessary infrastructure upgrades that will improve customer safety and
security, reduce operating costs and control future maintenance costs.
Environmental Responsibility 
Replacement of existing fixtures will reduce port-controlled greenhouse gas emissions and
reduce light and glare from Terminal 91 yard lighting. 
Community Benefits 
Neighbors of the Terminal 91 vicinity will be shielded from light and glare and appreciate the
active controls,  which will automatically reduce lighting levels when work is not being
performed or the property is not occupied. 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1)  Do not upgrade Terminal 91 lighting. Maintenance costs will continue to
increase due to an aging system, and energy use costs will continue to rise due to utility rate
increases. Alternative 1 is not recommended.

COMMISSION AGENDA 
Tay Yoshitani, Chief Executive Officer 
September 26, 2013 
Page 7 of 7 
Alternative 2)  Authorize $945,000 for a total project budget of $1,035,000 to upgrade to
lighting at Terminal 91. The lighting upgrade will potentially reduce energy used for lighting the
terminal by up to 76% while improving the quality of light and reducing light pollution.
Maintenance costs as well as energy costs will be reduced. This is the recommended
alternative.
