ACTION ITEM                   Date of Meeting   November 14, 2017 
DATE:    October 27, 2017 
TO:     Dave Soike, Interim Executive Director 
FROM:   Stephanie Jones Stebbins, Managing Director, Maritime Division and Director, 
Marine Stormwater Utility 
Srini Pendikatla, Stormwater Utility Program Manager 
SUBJECT:  2018 Marine Stormwater Utility Rates 

ACTION REQUESTED 
Request Commission authorization for the Executive Director  to  increase the Marine
Stormwater Utility 2018 rates by 7.75 percent. 
EXECUTIVE SUMMARY 
The requested authorization will provide a 2018 rate structure to be adopted by the Marine
Stormwater Utility, in support of utility obligations to protect stormwater and rehabilitate Port
assets. 
JUSTIFICATION 
A rate increase at the proposed level of 7.75% allows for our capital program to move forward.
This allows us to stay on track with our assessment of the overall system, maintain capital
investments on our infrastructure and pursue green stormwater infrastructure pilot projects.
Our rates will continue to be 12 to 15% below City rates. 
DETAILS 
The Marine Stormwater Utility was formed in 2014 to enable the Port to provide services,
facilities, systems, and programs for surface water and stormwater management and pollution
control. A benefit of Utility work is water quality protection in the Puget Sound. The Utility
collects stormwater fees from the Port, Northwest Seaport Alliance (NWSA) and their tenants
and reinvests the income into maintaining and upgrading the stormwater infrastructure. Prior
to creating the utility, most of the stormwater fees paid by the Port and its tenants were
diverted from the properties of the Port and its tenants to address City of Seattle priorities. 
The Utility Charter included rates for 2015 through 2017. The rates apply to all Port-owned
maritime property, which includes land managed by the NWSA. Tenants pay stormwater fees

based on the area of their leaseholds. The stormwater fees for the remaining unleased land in a
facility are paid by the operating business. The operating business is either the NWSA or the
specific Port business (Economic Development, Maritime Operations, Cruise, etc.) that oversees
the unleased property. 
Scope of Work 
All money collected by the Utility must be spent on stormwater expenses. To date, $1.7 million
has been committed/spent on capital for equipment to get the Utility up and running.
Additionally, approximately $5.7  million has been spent on expense activities, primarily
performing the assessments to obtain baseline data, urgent repairs, and administrative costs in
operating the Utility. Other efforts include billing and policy creation, and working with the City
on the interlocal agreement. There is an additional $6 million committed for capital works
through 2021, and about $7.5 million projected to complete the assessments by 2019, as well
as additional administrative costs. 
Four rate scenarios were considered for 2018 with the following criteria: 
(1) Maintain adequate spending levels to meet the Port's Environmental Long Range Plan
and Utility Charter responsibilities including rehabilitation of infrastructure and
funding stormwater compliance program by 2020. 
(2)   Continue progress on Century Agenda Goal to complete Port-wide stormwater line
assessments by end of 2019. 
(3)   Maintain 45 days of operations and maintenance expense cash reserve for financial
prudency. 
Schedule 
Once approved by Commission, the 2018 rates will be adopted by the Utility effective January
1, 2018. 

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  Increase rates by 4% consistent with the last 3 years and cut capital an average
of 36.6% from the Capital Planning forecast annually through 2021. 
Cost Implications: Projected revenue in 2018 will be $5,153,456 with a cash balance of
$305,290 by 2021. 
Pros: 
(1)   Full system assessments will be completed by the goal date of end of 2019. 
(2)   Increase at this level is expected by tenants and will likely result in minimal feedback. 
(3)   Port rates will be 16-20% lower than City drainage rates in 2018.
