Currently Phase 2 of the TIB street improvements are under design. Without the grant for
Phase 3 and in order to complete the entire highway, we will have to change the scope of the
project to a budget of only $9.5 million. We may however be able to include additional
monies from WSDOT and bring the budget to $12.5 million. Funding with or without the
WSDOT contribution will require a change in project scope and approval from Council. We
will then direct the current design to include any changes.

Tukwila International Blvd. Phases 2 3 (S 116 St to S 138 St)
Scope and Budget Alternatives
Project No. 95 -RWO3
ISSUE
Present scope alternatives based on secured funding and potential funding from WSDOT.
BACKGROUND
This project was presented to Transportation Committee in February 2003 where project limits
were discussed. The resulting consensus was the preference to complete roadway
improvements from the north limit of Phase 1 (S 138 St) to as far north as possible with the
available funding (just north of the Sabey development). This would eliminate having a "gap"
in improvements where Phase 3 is currently identified.
The City has subsequently learned about a WSDOT funded project that overlaps the City's
Phase 3 project and a portion of Phase 2. City staff is in discussions with WSDOT to transfer
state funds to the City to complete all desired /needed improvements with one project managed
by the City.
KPG, Inc., is under contract with the City to design Phase 2 of T.I.B. improvements. They
have developed scope and budget alternatives for the project limits from S 138'" St to S 116t St
based on the different funding scenarios. The estimated costs with descriptions of included and
excluded scope items are shown in the attached spreadsheet.
ANALYSIS
All alternatives are based on the same project limits from S 138 St to S 116t St. The scopes
and budgets shown are based on: 1) the original information developed within the design
report, 2) the current secured funding, and 3) the current funding plus the budgeted state
funds. The description shown for each funding alternative identifies scope items that are
assumed to be included or excluded in order to fit within each estimated budget.
RECOMMENDATION
Discuss the alternatives presented and provide direction to staff on desired scope items in order
to proceed with design of improvements.

South 138th STreet to South 116th Street
Scope and Budget Alternative
December 12, 2003
Underground all aerial utilities
New Illumination system
5 lane roadway section
4" planters with 8' sidewalks both sides
provide medians where left turn access is not required
4" planter with 8' sidewalk on west side for pedestrian connection to the Green River trail
No undergrounding - pole relocations only
Illumination on relocated utility poles
Transition to 4 lane section at Southgate and Riverton Creek crossings to reduce wall costs
Typically 4' planters with 6' sidewalks reduce to 6' sidewalk and no planter in some locations
to reduce wall costs
Minimal medians
Use roadway shoulder for pedestrian connection to Green River Trail
No undergrounding - pole relocations only
Budget would allow a new illumination system
5 lane roadway section
4' planters with 6' sidewalks both sides
provide medians where left turn access is not required
Curb or planter separation for pedestrian connection to Green River Trail

DRAFT

1. Tukwila International Boulevard Because the City did not receive a $4 million grant from
TIB they were hoping for, Phase 3 of TIB is short of funding. To address the issue, the
department decided to combine KPG's Phase 2 and 3 designs to see what kinds of savings they
could get. They showed the Committee some options they have found thus far. As
undergrounding costs are very high, the option saving the most money does not include
undergrounding from about S. 139` north on the highway. To do the two projects together with
only Tukwila money, one lane would be taken out in parts, with no planters in some positions,
and a road shoulder to get to the river. However, it is possible we will be able to use some
WSDOT fluids they had scheduled for using in the same area. If so, though there would still be
less undergrounding than if full funding were available, but five lanes would be maintained, and
medians would be put in where there are no left turns. The Committee agreed that changing the
undergrounding ordinance would be a policy decision the Council would need to make before we
could consider option 2 or 3. Joan said that topic is an item on the Council Retreat Agenda.
Information
2. Transportation Imnact Fees A recent court case showed that the City needs to formalize its
impact fee process. The long -term goal will be to change the Transportation Concurrency
ordinance. For now they have devised a table with impact fees based on the methodology in the
current comp plan. They showed the cost for several sections of roadway or intersections
calculated according to the RCW. Cost ranged from $280 /trip to $12,900 for the most expensive
cost/trip. Trips are calculated on the number of 4 -6 p.m.weekday peak trips. When asked what
other cities did, Cyndy said there is a large range of costing methods. Some cities have a flat fee,
and others negotiate every case. Some have different per cost trips for different areas of their
city. The Committee pointed out that the highest three cost/trip (Southcenter Parkway S. of 180`
Southcenter Blvd 51 t -TIB; and Klickitat Southcenter -I -5 flyover) should be looked at for options
that would reduce their high costs. Brent pointed out that one trip could involve several of these
areas, each with a separate cost/trip. Reschedule.
3. 2004 Committee Agendas Jim had a list of 11 potential committee agenda items. Some are
very large items, such as funding options for infrastructure improvements in the TUC. Almost
each of the policies could take several meetings. Staff mentioned that Renton wants a meeting
with the Transportation Committee to talk about the Strander project February 9` Information.
4. Relocation of City Light Facilities The Sound Transit (S.T.) project will require
undergrounding some Seattle City Light facilities. Staff pointed out those areas where they will
not be required to underground, areas where they'll need to raise the wire heights, and areas that
will be undergrounded. The area on S. 154 (Southcenter Boulevard) from 42 to TIB is still
under discussion, with the City's view that it needs to be undergrounded. Sound Transit wants
this agreement to be a separate contract with the City. With only four crews for the whole South
end, City Light will lend Sound Transit two of those four crews for this project. Information.
