ACTION REQUESTED: 
Request authorization for the Chief Executive Officer to execute a Developer Extension
Contract, and supporting Bill of Sale, Right of Entry and Easement documents, with the Highline
Water District in support of the BMF project, a component of the Rental Car Facility (RCF)
program. 
SYNOPSIS: 
The BMF project includes the construction of facilities and improvements to support the rental
car consolidated busing operation and existing employee parking busing operations. These new
facilities and improvements are located on Airport property in the vicinity of 28th Avenue South
and South 194th Street and are shown on the attached site and site utility plan (Attachment A).
The Commission previously authorized the budget for this agreement on February 2, 2010 and
the project is funded by a combination of Customer Facility Charge (CFC) revenues or bonds,
and the Airport Development Fund (ADF). The Developer Extension Contract specifically
includes a Bill of Sale that will transfer the ownership of the completed water facilities, built by
the Port as part of the BMF project, to the Highline Water District. The total estimate value of
these water facilities is approximately $150,000. 
BACKGROUND:
In February 2008, the Port of Seattle and Highline Water District entered into an Interlocal
Agreement, clearly identifying that Highline Water District was the exclusive water service
provider for Airport properties in this area. In order to proceed with the development of the
BMF project, the Port of Seattle needs to execute a Developer Extension Contract with Highline
Water District. The Developer Extension Contract ensures that the water main improvements 
constructed as part of the BMF project and turned over to the Highline Water District meet the
requirements of the District.
