Metropolitan Seattle, predecessor in interest to King County, a Washington County corporation
("County"), entered into an"Agreement for Joint Use and Oversizing of Sewerage Facilities
("1969 Agreement"); and
WHEREAS, Section 6 of the 1969 Agreement provided for the construction of a Relief
Sewer, or"alternate relief system" at such time as the sewer downstream from the Mill Creek
Interceptor was approaching its maximum capacity, estimated in the 1969 Agreement at 8.6
million gallons per day; and
WHEREAS, said downstream sewer has approached or is exceeding its maximum
capacity; and
WHEREAS, Section 6 of the 1969 Agreement also established that the City and the
District would jointly pay the County's cost to construct the Mill Creek Relief Sewer or an
alternate relief system with no cost to the County; and
WHEREAS, the County and the City have determined that engineering limitations make
construction of the Mill Creek Relief Sewer, as originally contemplated under the 1969
Agreement, technically unfeasible; and
WHEREAS, the City has obtained the right-of-way and is currently constructing an
arterial roadway, know as the 277th Street Corridor, with its eastern terminus at the intersection
of the Kent Kangley Highway (SR 516) and 116th Avenue Southeast (in the City's "East Hill"
area) and with its western terminus at the intersection of Auburn Way North/East Valley Highway
and Southeast 277th Street in the Green River Valley; and
WHEREAS, a major component of the City's 277th Street Corridor Project is a bridge
that links the region's East Hill area to the valley floor by crossing over the Green River; and
WHEREAS, most of the area being served by the Mill Creek Interceptor and planned to
be served by the Mill Creek Relief Sewer lies in the vicinity of the East Hill area and the District's
service area; and
WHEREAS, the County is contemplating the design and construction of a regional sewer
interceptor project, which will serve the City of Auburn, City of Black Diamond, City of Kent and
the District by providing increased regional capacity and the relief envisioned in Section 6 of the
aforementioned 1969 Agreement; and
WHEREAS, construction of any new crossings over or under the Green River is
potentially damaging to the river environment and necessary permits are extremely difficult to
obtain; and
WHEREAS, the City is amenable to designing and constructing two (2) twenty-four inch
sewer transmission facilities as part of its 277th Street Corridor Green River Bridge construction
project to provide the County the option to utilize this river crossing for its new regional
interceptor system, should the County's final planning incorporate that river crossing as part of its
ultimate design; and
WHEREAS, in consideration of the City's payment at all costs of design and construction
of these two (2) twenty-four inch sewer transmission facilities on its 277th Street Corridor Bridge
construction project, the County agrees to accept the various costs expended by the City on this
project as full and complete payment of the obligation to pay for construction of the Mill Creek
Relief Sewer or alternate relief system under the 1969 Agreement, and the County further agrees
to release both the City and the Soos Creek Water& Sewer District from any additional financial
obligation to construct the Mill Creek Relief Sewer or alternate relief system under the 1969
Agreement;

Section 1. The City will design and construct two (2) twenty-four inch sewer
transmission facilities as part if its overall 277th Street Corridor Green River Bridge construction

interceptor system from the County's East Hill area to connect to the County's main sewer
interceptor system in the Green River Valley that leads to the County's sewage treatment plant in
Renton, Washington.
Section 2. In consideration of the City's payment of all costs for design and construction
of these two (2) twenty-four inch sewer transmission facilities on its 277th Street Corridor Bridge
