Contract for Consultant Services related to the Supplemental Environmental
Impact Statement and Planned Action for the Tukwila Urban Center Plan
Background
As you will recall, a Supplemental Environmental Impact Statement (SEIS) is required for the
ruc Plan to analyze impacts and ensure that these impacts will be addressed as development
occurs. At our last COW meeting, the contract for the SEIS consultant was discussed. Concerns
were raised about the adequacy ofruC utilities and how utilities were being addressed in the
ruc Plan and the ruc SEIS. This memo will briefly describe how inITastructure for the water,
sewer and storm utilities will be addressed in the SEIS.
Current Infrastructure Plans and Impact Mitigation Mechanisms
Water and Sewer Utilities
Comprehensive plans for these utilities are now in final review by state agencies and will come
before the City Council for review and approval sometime this spring. Both comprehensive
utility plans are based on the development anticipated throughout the City, including that
described in the ruc Plan. The plans describe known and anticipated deficiencies for the
Tukwila water system, again including those located in the ruC. The plans then list, prioritize
and attach costs to infrastructure projects that will address these deficiencies. The water and
sewer utility rate structures provide funding for upgrades and maintenance to existing facilities.
The City's concurrency ordinance requires developers to pay for service to new projects,
including construction and dedication of any major facilities (lift stations, etc.) needed due to a
given project Sufficient water supply and sewer treatment capacity exist to serve all
development anticipated by the ruc plan.
Storm Drainage
The City Comprehensive Surface Water Plan was updated in 2004. This plan describes current
deficiencies for the Tubvila stormwater system. The plan then describes, prioritizes and attaches
costs to projects addressing these deficiencies. The surface water utility rate structure provides
for upgrades and maintenance to existing public facilities. The City does not have a concurrency
ordinance for stormwater facilities. This is because developers are required to ensure that no

impacts to water quality or the peak discharge rate occur. The City's stonnwater ordinance then
requires developers to de.sign and construct on-site stonnwater improvements to perfonn to City
standards, including on-site water-quality treatment. Theoretically, under this system, no further
downstream capacity or treatment is needed.
The exception is when there is no City system to discharge to. In this case, the developer would
be required to construct a conveyance system to get the stonnwater to either the City system or
directly to the river. The developer would also be required to mitigate any ancillary impacts of
the conveyance project as a condition of development.
Adequacy
In general, utilities are adequate within the roc. The primary exceptions to this are:
1) The mostly-undeveloped TOD area between the Sounder commuter rail station and West
Valley Highway, Current development in this area is spotty, as is the utility inftastructure
supporting it. Deficiencies in this area for all utilities are described and the costs are assigned in
the relevant utility plan.
2) The area east of the Mall near Andover Park West. A sewage line and the sewage lift station
in this area are reaching capacity. These projects are slated for construction in 2008 and 2010
respectively in the Tukwila CIP,
3) A storm drainage deficiency in the vicinity of Andover Park East and Minkler. This is slated
for upgrade in 2007 in the Tukwila CIP.
SEIS Approach to TUC Utilities
For each utility, the SEIS will surrunarize roc deficiencies outlined in each of the utility
comprehensive plans and describe
1) how current city plans and ordinances will address current deficiencies,
2) how current city plans and ordinances will address additional future inftastructure needed
due to development anticipated within the roc Plan
