ACTION ITEM                            Date of Meeting    September 10, 2019 
DATE:     August 5, 2019 
TO:        Stephen P. Metruck, Executive Director 
FROM:    Elizabeth Leavitt, Senior Director, Environment and Sustainability 
Arlyn Purcell, Director, Aviation Environment and Sustainability 
SUBJECT:  Procurement of an Indefinite Delivery, Indefinite Quantity (IDIQ) Professional Service 
Agreement for Hydraulic and Hydrology Support Services 
Total estimated contract cost:                      $   750,000 
ACTION REQUESTED 
Request Commission authorization for the Executive Director to execute one indefinite delivery,
indefinite quantity (IDIQ) consulting agreement for hydraulic and hydrology support services in
support of the Port's Aviation and Maritime Divisions with a cumulative total amountnot to
exceed $750,000 over five years. No funding is associated with this request. 
EXECUTIVE SUMMARY 
The Aviation Environmental Department proposes to advertise and select one qualified firm to
provide hydraulic and hydrology services. This IDIQ would be used to ensure development and
redevelopment projects meet the conveyance, pumping, detention, and water quality
treatment requirements of National Pollutant Discharge Elimination System (NPDES) permits
held by the Port. These services will help the Port meet our Century Agenda Strategy 4  to be
the greenest, and most energy efficient port in North America. 
This procurement will allow the Port to responsibly manage finances by providing a costeffective
means to utilize professional services for tasks that have variable workloads, are often
time sensitive, and require specialized expertise that cannot be effectively provided by Port
staff. The requested action is primarily for Aviation Division as there is a known demand for this
service at the Airport. At this time, Maritime does not anticipate a need for hydraulic analysis
however to provide flexibility Maritime has been identified as a potential user. The contract
administration will be performed by Aviation Environmental.  Funding for Service Directives
under this contract will either be from projects which have already been authorized or from
previously-authorized division operating budgets.  Consequently, there is no funding request
associated with this request.

JUSTIFICATION 
Services under this contract will support the Port's Century Agenda Strategy 4  to be the
greenest, and most energy efficient port in North America, and specifically Objective 14  Meet
or exceed agency requirements for stormwater leaving Port-owned or operated facilities.
Ongoing hydraulic and hydrology analysis is essential to ensure that the Airport maintains the
goal of 100 percent treatment and flow control of stormwater runoff that leads to our local
salmon-bearing streams and ultimately Puget Sound. 
Failure to comply with conditions of the NPDES permits will result in permit violations and
potential fines. Additionally, repeat violations can lead to more stringent permits in the future
that would increase the cost and resources to comply. Lastly, permit violations can increase
public scrutiny for Port operations and facilities, as well as decrease favorable relations with our
neighboring communities. 
Diversity in Contracting 
The Diversity in Contracting Department has been contacted regarding this procurement and an
aspirational goal of seven percent has been established for women- and minority-owned
business enterprise. 
DETAILS 
This contract will provide specialized hydraulic and hydrology expertise to support on-going
programs and future development projects. Work under this contract will occur primarily at the
Airport, with occasional small projects needed at Maritime properties. Individual service
directives consisting of a scope, fee agreement, and schedule will be negotiated and processed 
before any work is performed. Service directives will span over the life of the contract, which is 
expected to be five years. 
The Port's Building Department and NPDES permit require specific hydraulic and hydrology
submittals and analyses for the approval of permits for land-use changes (new construction or
re-development). 
Scope of Work 
Typical services would include  modelling,  studies and  investigations, design, permitting,
inspection, and design review for these types of project components: 
(1)   Stormwater 
(2)   Industrial wastewater 
(3)   Sanitary sewer 
(4)   Potable water and fire protection 
(5)   Streams and open channels 
(6)   Dam and embankment safety and stability 
(7)   Erosion and sediment control

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Costs for Alternatives 1 and 2 were estimated using best professional judgment. 
Alternative 1  Prepare separate procurements each time hydraulic/hydrology services are
needed. 
Cost Implications: $825,000 to 900,000 (plus approximately additional 0.1 to 0.15 FTE Port
staff) 
Pros: 
(1)   Smaller procurements spread out over many years instead of the one-time large
procurement effort. 
(2)   Ability to change consultants if need be. 
Cons: 
(1) Would require each new consultant to "start from scratch" for each small project.
Piece-meal smaller contracts (likely by different entities) would not provide the
necessary consistent and accurate tracking for ongoing changes to physical systems
(e.g., drainage system) and projects occurring over several years. 
(2)   Increased risk of model failures and inaccuracies. Many projects occur in the same
drainage basin and would not be able to establish/track baseline and ongoing
changes. 
(3)   Would increase overall consultant fees by an approximate 10 to 20 percent, as well as
increase Port staff time to procure and manage multiple smaller contracts. 
This is not the recommended alternative.

Meeting Date: September 10, 2019 
Alternative 2  Modeling and analysis conducted by Port staff. 
Cost Implications: $800,000 (consultant training and transition over first few years), in addition
approximately 1.0  2.0 new Port FTE, as well as software procurement/upgrades/licensing not
included in the cost implications. 
Pros: 
(1)   Contract  administration  would  be  eliminated  once  Port  staff  are  hired  and  fully
trained. 
(2)   Port environmental teams would increase overall technical capabilities. 
Cons: 
(1)   Requires a long transition period for consultant to train new Port staff. 
(2)   Current staff does not have experience or sufficient expertise in this area; several
years of training would be required. 
(3)   Potential hires in this specialized field are in short supply in this region due to high
demand. 
(4)   Costly specialized software to procure and maintain. 
This is not the recommended alternative. 
Alternative 3  Current proposal, IDIQ contract with work being done via Service Directives
along with existing Port staff management and interaction. 
Cost Implications: $750,000 
Pros: 
(1)   Lowest cost alternative 
(2)   Proven successful past model to complete this work. 
(3)   Avoids the Port having to develop staff with a highly specialized expertise. 
(4)   Third-party oversight (i.e., a "different set of eyes") 
Cons: 
(1)   Procurement effort. 
(2)   Competing needs with consulting firms other clients. 
This is the recommended alternative. 
FINANCIAL IMPLICATIONS 
Funding for Service Directives under this contract will either be from projects which have
already  been  authorized  or  from  previously-authorized  division  operating  budgets.
Consequently, there is no funding request associated with this request. 
ADDITIONAL BACKGROUND 
The Airport has had a National Pollutant Discharge Elimination System (NPDES) permit since
1980 that governs stormwater runoff, industrial wastewater, and sanitary discharges. Hydraulic

and hydrology support necessary to comply with the NPDES permit has been sourced via two
past indefinite delivery, indefinite quantity (IDIQ) consulting agreements since 2010. In 2010 an
IDIQ contract was awarded for $750,000. In 2016, a $6 million IDIQ contract was awarded
which included a much broader scope including environmental review and permitting that
served both maritime and aviation environmental.  The requested  IDIQ will replace the
hydraulic and hydrology scope of the existing contract which is nearing capacity.
