CITY OF DUBLIN
AGENDA STATEMENT
City Council Meeting Date: November 8, 1993
SUBJECT:
Tri-Valley Transportation Plan
Report by: Public Works Director Lee Thompson
EXHIBITS ATTACHED:
l)~atrix listing suggested Plan Potential Alternatives
2) ~List and map of expected roadway system
3)/Letter explaining potential projects for a regional
transportation improvement fee
4) ~sample resolution and letter proposal for extending
the scope of work and fees for the Tri-Valley
Transportation Plan
RECOMMENDATION: 1)
~{Y+-
Approve the extension of the scope of work for the Tri-
Valley Transportation Plan and authorize the transfer
of $4,375 from the City's budgeted Contingent Reserve
to pay Dublin's share of the cost.
2) Direct Councilmember Moffatt to deliver the following
recommendation to the Tri-Valley Transportation
Council:
a) As the firs,t.order of work, run the TVTC model
with the up-tO-date agency approved land use and
roadway plan, resulting in the "expected" scenario
(see the additional scope of work, Exhibit 4).
b) Report back to member agencies the problems
identified in the expected scenario and refer the
potential study alternatives back to the member
agencies for review and input prior to proceeding
on the alternative scenario and the Plan scenario.
c) After receiving each agency's comments on the
Transportation Plan Alternatives, analyze the
Study alternative solutions which will fit the
deficiencies found in the new model run.
FINANCIAL STATEMENT:
Additional cost to Dublin for the Study is $4,375. A
budget transfer will be required.
DESCRIPTION: The Tri-Valley Transportation Council (TVTC) has
prepared an area-wide traffic model and is charged with developing a Year 2010
transportation plan based on planned (but not necessarily approved) transportation
improvements and land uses. In order to go forward, the TVTC has requested
direction from the member agencies for further studies to match the expected rate of
growth with the assumed transportation system together with the desired levels of
service on the transportation system. These studies will need to be undertaken if
it is assumed that the variables will not match after the next model run.
A set of potential study alternatives has been developed by the Plan consultant and
they are categorized into four general areas:
1) Emphasize additional road improvements, primarily on the freeway system.
2) Emphasize transit improvements, including express bus service, density
transfers to transit nodes, and reduced levels of service on freeways.
3) Emphasize policy options, including improving arterial streets, reduced level
of service standards, and mandatory trip reductions.

4) Emphasize growth management including density transfers to transit nodes, and a
reduction in the rate of growth by the Year 2010.
A number of model runs have been undertaken as the various agencies have developed
their individual land uses programs, rates of growth and roadway systems. These
previous model runs indicate that there may be level of service problems on a number
of roadway segments (below LOS D on streets and LOS E on freeways). However, the
land use numbers on the last model run are not accurate and need to be revised.
These revisions may impact the deficiencies identified in the last model run. In
addition, it should be noted that the method of developing the Transportation Plan
is different from that used to analyze the Eastern Dublin Plan. CEQA required
Dublin to analyze land uses already approved by General Plan; while the Tri-Valley
Transportation Plan includes a list of approved projects, as well as projects still
on the drawing board but that may be approved.
As the latest land use and road system data input has not been run on the TVTC
model, Staff believes it is premature to consider study alternatives to rectify
unknown specific problems.
Staff would propose that this study alternative review be done after the expected
scenario model is run and the deficiencies are known.
Staff does agree that the consultant has had to do substantial additional work, and
that the project has been extended out in time due to the changes in the anticipated
land uses as a number of large General Plan changes have been processed by several
agencies in the study area. These changes will continue to happen between now and
the horizon year of 2010; however, TVTC is going to take a snapshot of the current
thinking and develop a transportation plan which will at least identify potential
transportation deficiencies given the most up-to-date land use assumptions
identified by the Tri-Valley agencies. As projects proceed and change over the next
sixteen years, modifications will have to be made to the plan to keep it up to date.

Re: Tri~ Valley Regional Transportation ImpacJ Fu
Dear Martin:
This letter responds to your request for modeling information that would he used to support a
regional trnnsportiltion impact fcc;. At the outset of our Transportation Plan/Action Plan study,
we prepared a preliminary analysis [or a potential impact fee program. The attached memo
describes this potential impact fee program.
.
The initial project list that we developed includes projects that we nre certain will he needed and
that are not fully funded at this time. Our recently completed year 2010 base forecasts have
confirmed the need for these fiJciltties:
1. 1-5801I-680 interchange improvements .
2. Route 84, six-lane freeway from 1.680 to 1-580
3. 1.680 auxiliary lanes, Diablo Rd. to Bollinger. Canyon Rd.
4. BART extension to East Dublin
5. 1-680/A1costa interchange improvements
6. 1-580lFoothil1 interchange irnprovcmenl3 _"~_
The preliminary analysis was presented to the Tri-Vallcy Transportation Council in March. 1992-
Their d~ision was to postpone further consideration of an impact fee untillhc CDmpletion of the
Tri-Yalley Tnmsportation Plan. However, lhey also reiterated their policy position atlhat time,
which is that impact fee monies collected in the Tri-Vallcy must be spent in the Tri-Valley.
Regarding your ~equest for select link ;miJlysis to study congested locations: the Tn-Valley TAC is
prepared to provide these data. llowever, we arc going to wait untillaler in the plan proces:!.
. We also want to stipulate that we intend 10 use our .composite" 2010 hase forccast (which will be
based on ABAG Projections '92) for the analysis of congested locations.

Re: Additional Scope and Budget for Tri- Valley Transportation Plan
Dear Brian;
This letter documents our request" for additional budget to exocute the additional scope
of work that has boon requested for the Tri.Valley Transportation Plan. The follo\l;'ing
describes the additional scope of work.
Scope of Work
Meeting Attendance. We have exhausted our budget fol' meeting attendance be<:ause
the project has gone longer than anticipated. With this extra budget request we have
allowed for attendance at about fifteen more meetings. This allowance will1ast for about
eight months given our current rate of meet.in~ attendance.
zone Splits. We have recaived requests from Contra Costa County, Dublin, and
Livarmore to add zones to the model. These will provide additional detail in the
Dougherty ValJoy, Tasaajara Valley, East Dublin, and North Livermore areas. In
addition to adding zones. we 'Nom be adding some street network to these areas. The
individual jurisdictions will be providing land use data to go with the new zones.
"Expected" Scenario. We need to make many changes to the highway and transit
networks and to the land use data in our 2000 and 2010 "expected" scenarios. Thcs~
changos respond to requests from roany jurisdictions to reviso our earlier assumptions.
We need to'rerun the Mexpect.edll scenarios and provide pluts showing forecast volumes,
transit ridership, volume-to-capacity ratioB, and intersection turning movements to
ostablish a basis trom which to evaluato the ultimate Transportation Plan. .
Additlonal Scenario. This will be the next step toward development of the ultimflte
plan. We have already run the four scenarios that were Bpecified in our original scope of
work. These allowed UBto define the parameters of 3. compromise plan, but they were
not enoui'h to result in the final plan. We have prepared a matrix of choices lor the
TVTC, which will allow them to give us direction for this additional scenariO. We
anticipate that t..~iB B<:enario will be close to the final plan. The product of this task will
be 0 fully documented model run including volume forecasts, link vIe ratios, intersection
levels of service, and transit ridership.
Plan Sc'enarlo. The results of the additional scenario descrihed above wiU 00 reviewed
in detail with the TVTC, and from that we will define the final plan. Thia task will be to
run the final plan "With themodel and document the results-attainment ofilia T80s on

February 1994. The remainder of the schedule, which ('xtends through June 1994, is to
rev.i~ the draft plan fl!it travels through the approval process. Four TVTC meetings are
anticipated to get final approvai.

at thn endofDecember 1993. This will document existing conditions and transportatiqn
service objectives on the Routes of Regional Significance and will also describe the plan
