EXHIBIT C
Stormwater Infrastructure Ownership Resolution and
Seattle Public Utilities Easements Needed from the Port of Seattle
This Exhibit of the Port of Seattle-City of Seattle Interlocal Agreement (ILA) Regarding Stormwater Utility
Operations includes proposed resolution of infrastructure ownership issues and easements needed by
the City of Seattle identified during the development of the Stormwater Map Books (SW Map Books).
1. Shilshole Bay Marina
The Port and City identified eight storm drainage "systems" that needed clarification of ownership
and/or property rights. These "systems" are shown on Attachment 1 and can be found in the
Seaport SW Map Book pages 3-5 (5/12/2016). The drainage "systems" involve a mix of
infrastructure on the adjacent hillside, pipes and inlets in the road that were originally installed by
the City when Seaview Drive was constructed, pipes that were extended by the Port from City lines
with few or no Port connections, and lines that may no longer exist or be operational.
A. Ownership Resolution
Using street use permit data, side-sewer card data, Seattle Public Utilities (SPU) and Port GIS data on
infrastructure, construction and current ownership records, and any existing easement records for
each "system," the Port and City verified current ownership and discussed future ownership of each
system. The construction information, current ownership, and resolution of ownership issues are
described below and summarized in Table 1.
i. North 1 and North 2. The drainage on North 1 and North 2 starts on Burlington Northern
Santa Fe Railroad (BNSFRR) property. Drainage infrastructure was likely first constructed by
the railroad. The City installed drainage in right of way (ROW) when Seaview Drive was
constructed. The lines were extended by the Port when Shilshole Bay Marina (SBM) was
constructed. North 1 and North 2 are natural drainages. On North 1, the City has inlets in
the roadway and the Port has two catchbasins behind a Port-controlled fenced area. On
North 2, the City has inlets in the roadway and the Port installed a sediment vault. The
sediment vault is partly on Port property and partly in ROW in Port parking area.
Since North 1 and North 2 involve BNSFRR, the City and the Port, the ownership of these
lines will be as follows: 1) the City owns and is responsible for maintaining drainage
structures from the western edge of BNSFRR property line to the western edge of the
sidewalk, and 2) the Port owns the infrastructure from the western edge of the sidewalk to
the outfall.
The Port and City recognize that North 2 is a natural drainage course that drains BNSFRR
property. The City and the Port will continue to work cooperatively to address sediment
concerns, including working with BNSFRR. The City will continue to implement municipal
authorities described in Section 3 of the ILA.

ii. Central 1, Central 2, South 2 and South 4. These four lines were originally installed by the
City when Seaview Drive was constructed. The lines were extended by the Port when the
SBM was constructed. Because the Port has few or no connections to these systems, the
City intends to take ownership of the portions extended by the Port if these lines are in
acceptable condition to SPU. SPU and the Port will work out the responsibilities and costs to
CCTV the lines and clean them. SPU and the Port will jointly discuss the condition, identify
needed repairs and timing of repairs, and identify any work needed before the City takes
ownership. The work to resolve the ownership will be completed within one year of the
signing of the ILA. If City agrees to take these lines, SPU and the Port will enter into an asset
transfer agreement. There will be no charge between the City and the Port for the transfer.
If the Port and City cannot reach agreement on conditions and repairs, the Port will continue
to own the extended portions of the stormdrains.
iii. South 1. Port owns the majority of South 1, which was constructed by the Port to serve Port
property. The City will own and operate the portion of the line in the road to the western
edge of the sidewalk.
iv. South 3. The City assumes ownership of South 3 given existing SPU easements in this
location. The Port and SPU will field verify what infrastructure exists. These may be
drainage, sewer or combined lines.
B. Easement Acquisition
Following ownership resolution of Central 1, Central 2, South 2 and South 4, the Port will grant the
City one Master Easement for the SBM area. SPU and the Port will evaluate if the existing
easements on South 3 should be incorporated into the new Master Easement. The easement work
will be completed within two years of the signing of the ILA. The Port will not charge the City for
these easements.

2. Terminal 91
Two stormdrains from the hillside above Terminal 91 drain City ROW (Attachment 2). These
connections are on page 8 and 9 of the Seaport SW Map Book. Construction documentation could
not be found. These drains are:
1) Port Connection 12: pipe from catch basin/structure in the gutter along 23rd Ave W (near W
Crockett St) to the connection with Port approximately at MH D027-236.
2) Port Connection 13: pipe from MH at the dead end of W Plymouth St to the connection with
Port approximately at MH D027-037.
A. Ownership Resolution. The City assumes ownership of the two storm drains since they drain
City rights-of-way. The Port and SPU will work together to determine the specific connection
locations taking access into consideration. The connection points will be agreed upon within one
year of signing of the ILA.
B. Easement Acquisition. After determining the connection points, the Port will grant the City one
master easement for the two locations within two years of signing the ILA. The Port will not
charge the City for the easement.
3. Terminal 115
In 1993, the Port reconstructed a City storm drain around a building on T-115 as shown in
Attachment 3, Storm Drain Relocation Vault Plan 877-53. The plan notes that an easement was to be
acquired. As part of the reconstruction work, a storm drain under the building was abandoned.
A. Easement Acquisition and Relinquishment. The Port will grant the City an easement. The City
will relinquish the existing easement (recording #7510150842) accepted by Ordinance #105301
for the pipe that was abandoned during construction. The Port will not charge the City for the
easement since this work was to be completed more than 20 years ago.
4. Vicinity of South Spokane Street and East Marginal Way near T-104
The City will need to acquire a master easement for infrastructure in the vicinity of Terminal 104
along South Spokane Street area and East Marginal Way (see Attachment 4). This area is shown on
Seaport SW Map Book page 28. A title report initiated by SPU shows a complex parcel ownership,
and that City infrastructure cross back and forth between public and Port-owned property.
A. Easement Acquisition. The City and the Port will work cooperatively to create an accurate map
of parcel ownership and infrastructure ownership in order to identify easements needed. This
work will be completed within one year of the signing of the ILA. The Port will then grant the
City one master easement in this area within two years of the signing of the ILA. The Port will
not charge the City for the easements.

Limitations of Translatable Documents
PDF files are created with text and images are placed at an exact position on a page of a fixed size.
Web pages are fluid in nature, and the exact positioning of PDF text creates presentation problems.
PDFs that are full page graphics, or scanned pages are generally unable to be made accessible, In these cases, viewing whatever plain text could be extracted is the only alternative.
