SPONSOR'S Staff has calculated that the Fort Dent Sewer Lift Station #6 is over capacity during large
SUMMARY events at the Starfire Sports Complex. The best solution is to reroute the flows from Lift
Station #5 that serves Family Fun Center and the business park along Interurban Ave S
and leave Lift Station #6 to just serve Fort Dent Park. The estimated costs have escalated
to $917,500 and a transfer of funds is needed from other projects so that this project can
be completed this year.

ISSUE
The existing sewer Lift Station #6 that services Fort Dent Park is over capacity during large
events at the Starfire Sports Complex.
BACKGROUND
Lift Station #5 serves Fort Dent Business Park and the Family Fun Center and then pumps its
flow to Lift Station #6. Lift Station #6 takes the flows from Lift Station #5 and the Starfire
Sports Complex and pumps to the Renton Treatment Plant. It was determined during testing in
2003 and reconfirmed on July 27, 2006, that the two pumps at Lift Station #6 each have a
capacity of 230 gallons per minute (gpm)
The consultants for Starfire Sports Complex, Berryman Henigar, Inc., stated in their August
8, 2003, design report that the sewage flows from the sports complex would be approximately
125 gpm and that the amount would be reduced to 83 gpm by the use of low flow toilets and
other plumbing fixtures.
In June 2006, the City of Tukwila contracted with ADS Environmental Services to monitor
sewer flows going into and out of Lift Station #6. The placement of the flow monitors allows
the City to accurately calculate the amount of sewage generated just by the Starfire Sports
Complex.
ANALYSIS
On July 15 and 16, 2006, the opening weekend of the All Nations Cup Soccer Tournament, the
design capacity of Lift Station #6 was exceeded 10 times in 48 hours. The flow peaked at 292
gpm on July 16, 2006, at 4.30 p.m. The sewer flow rate of 292 gpm indicates that both pumps
are needed at the same time to keep up with demand. Lift Station #6 was not designed for this
high amount of flow Even though the lift station contains two pumps, it is designed so that
only one pump is needed to keep up with the peak demand. The second pump acts only as a
backup
The City has calculated that the July 16 peak flow of 292 gpm was a combination of 118 gpms
from Lift Station #5 and 174 gpm from the Starfire Complex. Starfire's flow is double the
quantity estimated by Starfire's consultant, Berryman and Henigar

In 2003, the City determined that with the addition of the Starfire Sports Complex, Lift Station
#6 capacity would be exceeded. If at all possible, the City did not want to upgrade the sewer
force main from Lift Station #6 to the Renton Treatment Plant because it is located in the tow of
the Green River levee and goes under the BNSF/UP railroad tracks. Also, to accommodate
Starfire's construction schedule and to keep costs down, the City decided that the best solution
was to reroute the flows from Lift Station #5 along Interurban Ave S to an existing gravity
sanitary sewer With the new gravity sewer installed in Interurban Ave S, Lift Station #6 could
be dedicated entirely to the Starfire Sports Complex.
The City created a CIP project for the Starfire Sewer Upgrade, page 11 in the 2006 CIP
Construction was estimated at $755,000, including contingency and construction management.
The City had expected to receive $205,000 from Starfire and $400,000 from King County The
City committed $150,000 to the project.
Since that time, materials and labor costs have escalated significantly The estimated cost of the
project has grown to $917,000, see breakdown below Adding to the City's funding problem is
Starfire's reluctance to contribute (now under litigation) and King County's reduction of their
contribution from $400,000 to $150,000 The funding shortfall is $617,500 To make up for
this shortfall, it is proposed that dollars be removed from Traffic Calming, Macadam Winter
Garden, Codiga Farm Park, S 144" St Sidewalk Study, the 303 Fund, and the Sewer GIS
Inventory Project. The funds are still available and have not been obligated at this time.
The construction costs and the revenue sources for the new gravity sewer in Interurban Ave S
are listed below The page numbers listed are in reference to the 2006 CIP

Utilities Committee
August 8, 2006 5:00 p.m.
Present: Jim Haggerton, Chair; Pam Linder, and Verna Griffin
Jim Morrow, Director of Public Works; Frank lriarte, Deputy Director, Bob Giberson, Acting City Engineer; Mike
Cusick, Senior Engineer, Pat Brodin, Operations Manager Gail Labanara, Public Works Analyst; and Diane
Jenkins, Administrative Assistant to the Council.
Business Aaenda
A. AT &T Corooration Franchise Aareeriment
Mr. Frank Iriarte related that AT &T submitted a franchise packet on June 28, 2006. AT &T recently acquired Touch
America's fiber optic system and recently purchased conduits and associated fiber infrastructure from 360 Networks.
They would like to expand their fiber optics network (a map showing the expansion was reviewed). It was noted that
AT &T did want some changes to the standard agreement such as a reduction of the administrative fee from 55.000 to
52,500, changes in the requirement to underground the utilities, challenged providing'as- builts,' etc. None of these were
incorporated into the standard franchise agreement. Mr Haggerton noted that both underground and above ground are
considered part of cities' rights -of -way. He referred to the third 'Whereas, the City Council...from the standpoint of
benefits to be derived by focal business He asked if AT &T was only going to provide service to businesses. Mr Made
indicated that at this time, they have no installations planned for residential customers. In the future, as they seek
additional expansion, this issue could be addressed. A draft of the proposed franchise agreement was provided. There
should be no construction activity other than'accessing manholes and pulling fiber along the conduit route. Unanimous
approval; forward to Committee of the Whole.
B. Citv Government Channel
Mr. blade indicated that the City has notified Comcast of its intent to operate a dedicated government channel as
authorized by the franchise agreement. This is in addition to the public access channel. This would allow the City to
broadcast a wide array of public information such as road closures and public meeting notices to residents and
businesses. Ms. Linder noted that the Council has not yet decided to televise council meetings due to funding; additional
equipment would be required. Mr Iriarte continued and related that there will be approximately 525,000 in capital costs.
These costs could be paid from either the City's general fund or via a 25 cent fee to Comcast's subscribers. There are
approximately 4,300 subscribers and they would be assessed this amount on a monthly basis for two years. Ms. Griffin
requested that Comcast be asked how this fee would appear on a customer's bill. Concern was expressed on the number
the fees and taxes placed on many services such as cell phones. Mr Haggerton conveyed that only Comcast subscribers
would be able to view this information, however, this would be another tool which could be used to facilitate
communication with residents. Unanimous approval; forward to Committee of the Whole.
C. Budget for CWA and RCFCs
Mr. Pat Brodin reported that increases are projected for Cascade Water Alliance (CWA) for 2007 on wholesale supply and
Regional Facilities Charges (RCFCs). The philosophy for RCFCs is that 'growth pays for growth' in order to keep rates
reasonable for consumers. In 2006, the RCFC almost doubled. In 2006, the fee was $4,648 and it is being proposed to
increase to $5,297 This is based on current construction estimate of 4% rather than the original assumption of 3 A
copy of an article, 'Rising costs are hurting road projects statewide,' related that due to rising asphalt and other raw
materials, there are dramatic increases in construction projects. A copy of the member payments for the CWA was
reviewed and discussed. Mr Morrow stated that it is the intent that all developers' costs are paid upfront or made knovm
to the consumer so that these costs could be financed by them. Information only.
D. Fort Dent Park Sewer
Mr. Morrow indicated the capacity of lift station #6 that services Fort Dent ParkWStarfire is over capacity A sewer flow
monitor was used during the opening weekend of the All Nations Cup and the design capacity was exceeded 10 times in
48 hours. Even though the lift station has two pumps, it is not designed for this high amount of flow. It is designed for one
pump to serve as back -up; crews alternate the pumps. This must be remedied. Because of the placement of the flow
ymonitors, it was determined that Starfire's flow is double the quantity estimated by Stafire consultant, Berryman and
Henigar. The graphs showing the flow were/ reviewed. You are required to deal with the maximum amount of flow.
Mr. Morrow explained the rationale for not u Jgrading the sewer force main from lift station #6 to the Renton Treatment
Plant it is located in the tow of the Green River levee and goes under the railroad tracks. To accommodate Starfire's
construction schedule and keep costs down (see article referenced above), the best solution would be reroute the flows
from lift station #5 along Interurban Ave. S to an existing gravity sanitary sewer Then lift station #6 could be dedicated to
Stafire Complex. Family Fun Center recently made application for Phase 3 of their project which will be smaller than
originally proposed. Mr. Morrow reviewed funding for the project In 2003, construction was estimated at 5755,000 with
Starre contributing 5205,000 (approximately 30% of the Fonstruction cost) and King County, 5400,000. The City had
committed 5150,000. Since that time, construction costs have greatly escalated and the estimated cost for the project is
5917,500. At this time, Stafire is reluctant to make a contribution and King County reduced its commitment to 5150,000.
To make up the 5617,000 shortfall, a reallocation of projects within the Capital Improvements Project (CIP) budget was
proposed. He reviewed the reallocation of budget from traffic calming (5190,000), Codiga Farm (538,000), S. 144" St.
sidewalks/I-5 overpass (525,000), 303 Fund (5300,000) and sewer GIS inventory (590,000). With the Fort Dent revenue
(5150,000) and King County's contribution (5150,000) this would total 5943,000 for this project. These projects will be
funded at a later date. As a contingency, if the bids are higher than expected, funds from the winter park could also be
used. Mr Haggerton noted that he would inquire as to why King County's contribution was reduced.
Unanimous approval; forward to Committee of the Whole.
