Analysis was proposed for adoption, and (4) a public notice was posted 10 days in advance of the
meeting.
NOW THEREFORE, BE IT RESOLVED THAT the City Council of the City of Dublin, in
accordance with Government Code § 66001(a) and based on the information presented in the
2020 Nexus Study, adopts and approves the 2022 TVTD Fee rates shown in the table above and
makes the following findings:
1. Identify the purpose to which the fee is to be put. Response: TVTC policy, as expressed
Reso. No. 86-22, Item 6.1, Adopted 06/21/2022 Page 4 of 5
through the TVTC Action Plan, is that new development shall contribute for the mitigation of their
impacts on Routes of Regional Significance and that the cost-sharing of recommended
improvements will be implemented through the Tri-Valley Transportation Development Fee
regional impact fee program. The fee advances a legitimate public interest by enabling the TVTC
to fund improvements to transportation infrastructure required to accommodate and mitigate the
impacts of new development. This finding is documented by the analysis of the projected increase
in future travel generated by the new development that is projected to occur in the Tri-Valley.
Growth in new residents and employees is projected to increase the cumulative average daily
delay on the Tri-Valley regional roadways in the morning and evening peak hours, excluding
effects from more cut-through traffic.
2. Identify the use to which the fee is to be put. Response: The TVTD Fee will be used to
fund projects to expand capacity, traffic signal coordination, and other traffic improvements,
improve safety, improve regional transit, improve active transportation/bicycle options, and
mitigate the impacts of additional congestion on Routes of Regional Significance to serve new
development as designated in the Strategic Expenditure Plan. The projects/public facilities to be
funded by the fee are identified in the 2020 Nexus Study and the SEP and the Prioritization of
Projects and Funding Plan.
3. Determine how there is a reasonable relationship between the fee’s use and the type of
development project upon which the fee is imposed. Response: Based on the analysis in the 2020
Nexus Study, the new development projects within the Tri-Valley will generate additional trips
which will impact the transportation system in the region, including on Routes of Regional
Significance. As illustrated in the 2020 Nexus Study, the planned projects will expand and improve
capacity on the Routes of Regional Significance and alleviate congestion to accommodate the
increased trips generated by new development. Thus, there is a reasonable relationship between
the use of the fee for these projects and the new development generating these additional trips
on which the fee will be imposed.
4. Determine that there is a reasonable relationship between the need for the public facility
and the type of development project on which the fee is imposed. Response: The need for the
planned projects is based on the forecasted increase in congestion on Routes of Regional
Significance, as well as other transportation impacts resulting from new development. The 2020
Nexus Study analyzed the contribution by each land use based on the proportion of average
AM/PM trips generated by each land use. As demonstrated in the Study, there is a reasonable
relationship between the need for the planned projects and the types of development upon which
the fee is imposed because the planned projects will mitigate the transportation impacts generated
by new development.
5. Determine that there is a reasonable relationship between the amount of the fee and the
cost of public facilities or portion of the public facilities attributable to the development on which
the fee is imposed. Response: The 2020 Nexus Study demonstrates that there is a reasonable
relationship between the amount of the proposed fee and the cost or portion of the cost of the
public facilities attributable to the development on which the fee is imposed because each land
use category’s share of the total trips generated was multiplied by the applicable project costs
and then divided by the total number of units, square feet or trips that will occur within the
development horizon. In this way, there is a reasonable relationship between the amount of the
fee and the cost attributable to each land use type because the fee applicable to each land use
type is based on the number of trips generated by that applicable land use type. Furthermore, the
2022 TVTD Fee is proposed to be set at between 6% to 15% of the justified maximum fee rate
Reso. No. 86-22, Item 6.1, Adopted 06/21/2022 Page 5 of 5
and thus, the amount of the fee is lower than the actual costs attributable to new development.
BE IT FURTHER RESOLVED THAT the City of Dublin will:
1. Require each project developer to pay the TVTD Fee prior to issuance of building permits
for the project, or no later than occupancy, and to the extent permitted by law.
2. Levy the TVTD Fee on all development projects not exempt from payment of the fee.
3. Apply the TVTD Fee on all significant changes to existing development agreements
adopted after the effective date of the JEPA. The TVTD Fee shall be applied to all components of
a project that are subject to an amended or renewed development agreement. As used herein,
“significant” means any of the following: (a) change in land use type (e.g., office to retail); (b)
intensification of land use types (e.g., increases in square footage of approved Office); (c)
extension of the term of development agreements; and (d) reduction or removal of project
mitigation requirements or conditions of approval.
BE IT FURTHER RESOLVED THAT the City Council of the City of Dublin finds that the
foregoing recitals are true.

EXECUTIVE SUMMARY
Completed and adopted in early 2008, the Tri-Valley Transportation Council (TVTC) Nexus Study: Fee
Update (“2008 Nexus Study”) identified 22 projects that the TVTC elected for eligibility to receive funding
from the Tri-Valley Transportation Development Fee (TVTDF). The first 11 projects (List A, Table 13) were
adopted into the original program in 1995. The second set of 11 (List B, Table 13), were new projects that
were included in the 2008 Nexus Study. The travel demand modeling documented in the 2008 Nexus Study
projected that these projects would reduce the congestion created by new development within the Tri-
Valley.
Since 2008, there have been changes in the funding, planning and traffic conditions under which the TVTDF
was originally developed. In addition, many of the 27 original projects have been completed and the TVTC
has identified 23 new projects (List C, Table 14) to be considered. Based on these factors an updated nexus
study is needed to support updates to the TVTDF.
FORECAST GROWTH
New development within the Tri-Valley is forecast to add 33,312 household and 63,947 jobs between 2018
and 2040. This growth will produce an increase of 57,596 average AM/PM peak hour trips.
PROJECT BENEFITS
Based on forecast projection, the vehicle hour of delay is expected to increase by 60 percent during the
AM and 88 percent during the PM peak. With the construction remaining improvement projects, this delay
is expected to decrease by 15 percent during the AM peak and 23 percent during the PM peak when
compared to the 2040 No-Build Scenario. In addition, these projects will result in other benefits to the Tri-
Valley Area including improving roadway safety, improving roadway operations, and increasing bicycle
ridership.

Note: Hours of delay are based on trips with origin or destination in the TVTC region.
UPDATED FEE
The total investment for projects eligible to receive TVTDF funding is estimated to be $4.470 billion, where
$3.677 Billion is unfunded. An additional reduction was applied to account for external “cut-though” trips on
roadway congestion projects. Future development within the Tri-Valley area is not responsible to pay for
these trips since these trips are caused by growth outside of the Tri-Valley area. This reduces the total
unfunded cost to be covered by the maximum TVTDF to $2.928 billion. Note that this does not change the
overall project costs.
The $2.928 billion unfunded cost was allocated across future development land use type based on the
proportion of forecast peak-hour trips to determine the Total Fee per Land Use. Then the maximum fee
schedule was determined by dividing Total Fee per Land Use by the 2020-2040 Growth as shown in Table
E-1 below.
Table E-1: Maximum Fee by Land Use Category
Land Use Type Growth Maximum Fee
Single-Family Residential 15,857 DU $43,976 per DU
Multi-Family Residential 17,456 DU $25,928 per DU
Retail 5,117,500 SF $84.52 per SF
Office 6,796,800 SF $58.72 per SF
Industrial 9,289,800 SF $33.81 per SF
Other 12,441 trips* $50,839 per trip*
* Average AM/PM trip
The maximum fee schedule shown in in Table E-1 would generate sufficient revenues to fund the total
unfunded cost of all selected projects, however TVTC jurisdictions are not obligated to apply this fee
schedule. For instance, the TVTC jurisdiction set rates at approximate 1/3 of the maximum fee calculated
in the 1995 and 2008 Nexus studies to help foster growth within the Tri-Valley area, while providing a
regional funding source that could be used to match and help compete for Federal and State transportation
grants and funding programs.

August 2021 │ Final 1
1 INTRODUCTION AND BACKGROUND
1.1 BACKGROUND AND HISTORY
In 1991, the seven jurisdictions of Alameda County, Contra Costa County, Dublin, Pleasanton, Livermore,
Danville, and San Ramon signed a Joint Powers Agreement (JPA) that established the Tri-Valley
Transportation Council (TVTC). The purpose of the JPA was for the joint preparation of a Tri-Valley
Transportation Plan/Action Plan (TVTP/AP) for Routes of Regional Significance (RRS) and cost sharing of
recommended improvements. The TVTP/AP was prepared and presented to all member jurisdictions in
April 1995 and updated in 2000. The TVTP/AP created a common understanding and agreement on the
Tri-Valley’s transportation concerns regarding prioritizing projects for funding and implementation.
In addition to the project priorities, the TVTP/AP also recommended the development of a TVTDF to allocate
a fair share of regional infrastructure cost to go towards new development. The nexus study for the fee
program, completed in 1995, justified allocating the unfunded cost needed to complete all of the 11 projects
identified in the TVTP/AP to new development. The TVTC, however, recommended scaling back by roughly
two-thirds the total amount the fee program would collect from the maximum funding needed. The TVTC
and its member jurisdictions subsequently created and adopted the TVTDF in 1998 through a Joint Exercise
of Powers Agreement (JEPA). The original Strategic Expenditure Plan (SEP) was adopted in 1999.
The JEPA called for a periodic update of the fee program to reflect any significant changes in population
growth, project status, and other conditions that would require revisions to the fee program. Since 1995,
there have been substantial changes in the funding, planning, and traffic setting in which the TVTDF was
originally developed. New funding sources were established; the TVTP/AP was updated in 2000; projects
were completed; project schedules and/or funding plans shifted; traffic patterns changed; and new regional
transportation projects were identified through various traffic studies. The TVTC responded to these
changes by directing the Technical Advisory Committee (TAC) to conduct its first update to the fee nexus
study to update the fee and project list.
Completed and adopted in early 2008, the first update to the TVTC Nexus Study: Fee Update (“2008 Nexus
Study”) identified 22 projects that the TVTC elected for eligibility to receive funding from the TVTDF. The
first 11 projects (List A, Table 13) were adopted into the original program in 1995. The second set of 11
(List B, Table 13), were new projects that were included in the 2008 Nexus Study. The travel demand
modeling documented in the 2008 Nexus Study projected that these projects would further reduce
congestion created by new development within the Tri-Valley. A revised fee structure was released by
TVTC for consideration by each member agency in late 2008. While each member agency communicated
support for the revised fee structure, it was not approved by all member agencies pending preparation and
approval of a corresponding SEP. A TVTC SEP Subcommittee was therefore formed to commence
preparation of an SEP.
To facilitate the progress of existing projects while an update to the SEP was underway, an Interim Funding
Plan was approved by TVTC in April 2010. The Interim Funding Plan matched the programmed amounts
and priorities established in the 2004 SEP Update. It also included a revised disbursement timeline to reflect
the current Joint TVTDF account balance and projected fee collections over the next five years.
With respect to the TVTC JEPA, in October 2013 TVTC entered into a new Joint Exercise of Powers
Agreement (JEPA) comprised of seven member agencies: the County of Alameda, the County of Contra
Costa, the City of Livermore, the City of Pleasanton, the City of San Ramon, the City of Dublin, and the
Town of Danville. The purpose of the new JEPA agreement was to establish the TVTC as a
separate agency responsible for planning, coordinating, and receiving disbursement of traffic impact fee
Tri-Valley Transportation Council │ 2020 Nexus Fee Update Study

revenues from member agencies to help implement transportation improvement projects within the Tri-
Valley Area.
Strategic Expenditure Plan (SEP)
In January 2015, the TVTC adopted Resolution No. 2015-01 – Adopting the updated Tri-Valley
Transportation Development Fee Schedule as a two-year phase-in plan, with no change during the initial
year (FY 14-15), an increase to 25% of the maximum allowable rate by the fee nexus study in the second
year (FY 15-16) and a final increase to 35% of the maximum allowable rate by the third year (FY 16-17).
The new fee was based on the Fee Nexus Study adopted in 2008.
In November 2015, a review of the 2008 Nexus Study was conducted to determine if the analysis
establishing a reasonable relationship between the unexpended fees and the purpose for which those fees
were collected remained valid. This review analyzed the 2008 Nexus Study Fee Update with current traffic
conditions, forecasted growth, and project updates and found that the analysis establishing a reasonable
relationship between the unexpended fees and the purpose of which those fees were collected was still
valid. The review also identified a number of conditions that had changed since the completion of the 2008
Nexus Study, such as growth projections were lower in the more recent forecasts than at the time of the
2008 Nexus Study. This translated to lower trip generation rate from new development. In addition, a
number of the projects in the Nexus Study had been completed or had a change in project description or
cost estimate. However, due to inflation and updated cost estimates, the total unfunded project cost had
only decreased by 9 percent. The minor decrease in unfunded cost, paired with a decrease in expected
new peak hour trips to which the fee would be applied, meant that the maximum fee identified in the 2008
Nexus Study would be higher in an updated calculation.
In January 2017, the TVTC approved the 2008 TVTC Nexus Study Validation Review and adopted the
2017 Strategic Expenditure Plan (SEP)* Update. At that time, the TVTC elected to maintain the current fee
rate, with exception of the annual Construction Cost Index (CCI) adjustment. The 2017 SEP update
incorporated and built upon the updated project descriptions, funding programs, and progression of the
TVTDF over the previous six years. Some of the transportation improvement projects on the original list
were completed and schedules and funding for others had changed. The JEPA, adopted in 2013, required
approval for the SEP, by a supermajority of the TVTC – six members.
Since 2008, there have been changes in the funding, planning and traffic conditions under which the TVTDF
was originally developed. In addition, many of the 22 projects have been completed and the TVTC has
identified 16 new projects (List C, Table 14) to be considered. Based on these factors the 2020 updated
nexus study was undertaken.
On August 16, 2021, the TVTC approved Resolution No. 2021-10 Adopting the Tri-Valley Transportation
Council 2020 Nexus Fee Update Study.

2 FORECAST OF NEW DEVELOPMENT AND TRAVEL DEMAND
This chapter describes the methodology, assumption, and results for travel demand forecasting.
2.1 METHODOLOGY AND APPROACH
Travel demand forecasting was conducted using the current version of Contra Costa Transportation
Authority Travel Demand Model (CCTA TDM). The use of the CCTA TDM is consistent with the previous
2008 Nexus Study. Based on the outcome of initial discussions with the TAC, the following steps were
taken regarding the development of travel demand forecasts:
• Travel demand forecasting was reaffirmed to be based on the latest version of CCTA TDM. In 2019,
the CCTA TDM was updated to incorporate assumptions consistent with the current (as of 2017)
Metropolitan Transportation Commission (MTC) Regional Transportation Plan (RTP). A 2018 base
year validation was also completed as part of that update. The growth projections were based on
a base year of 2020 and a horizon year of 2040. Note that the CCTA TDM base year was updated
to reflect 2020 conditions and that the 2040 horizon year was also modified to address the specific
needs of this study.
• Land use assumptions for households and employment were broken down for the 2020 base and
2040 horizon years by jurisdiction and were distributed to member agencies for review. Detailed
data submitted to each jurisdiction included household and employment data at the traffic analysis
zone (TAZ) level. In addition, supplemental data from the Alameda County Transportation
Commission (ACTC) travel demand model was also provided to member agencies within Alameda
County. Kimley Horn worked closely with the individual agencies to appropriately finalize growth
forecasts prior to their use in the final modeling for this study.
Given that a recent land use forecast for the Tri-Valley region already exists as incorporated into the 2019
update of the CCTA Model, it is important to provide a context for the basis of this forecast. Specifically, the
focus of this effort, unlike the more recent application of the CCTA model which was in support of a Region‐
Wide RTP, is confined to a limited area that primarily includes City of Dublin, Pleasanton, Livermore,
Danville, and San Ramon and parts of unincorporated Contra Costa and Alameda counties. As this
constitutes sub‐area analysis (although the entirety of the model will be used during analysis), the typical
best practice includes carefully assessing land use within the study area to make sure that it is prepared in
a manner consistent with the specific goals of the study for which the TDM will be applied. It is important to
note that TDMs used in support of RTPs are prepared in accordance with strict control totals and, as such,
their land use forecasts do not necessarily reflect certainty as to whether a given development will occur,
rather they are more akin to a process of prioritization (the forecaster determines the magnitude and
location of development that is most likely to occur rather than determining whether something will NOT
occur). Not surprisingly, local jurisdictions sometimes have more detailed perspectives on whether certain
concentrations of development within their communities will occur before the RTP planning horizon. A land
use assessment, such as that carried out as part of a typical sub‐area analysis, is often an opportunity to
reconsider jurisdictional land use input without the necessary limitations that an RTP puts on land use
forecasting.
Based on these considerations and information shared by the TAC members, as well as input from staff
from the member agencies at several individual agency meetings, it was determined that the 2040 land use
forecast for the study area as included in the 2019 version of the CCTA TDM had unlikely development
patterns in several locations within the study area as compared to the collective perspectives of member
Tri-Valley Transportation Council │ 2020 Nexus Fee Update Study
August 2021 │ Final 5
agencies. Accordingly, it was agreed that a process to refine the existing CCTA forecast in a manner that
could be reasonably justified based on readily available information and data would be undertaken.
Specifically, this forecast is intended to reflect both realistic and achievable 2040 growth within the study
area, and not necessarily circumstances that would be reflective of the full potential of the study area or an
overly conservative approach such as a “worst‐case” scenario.
2.2 TRAVEL DEMAND FORECAST
This section presents the growth forecast based on feedback from member agencies.
2.2.1 HOUSEHOLD GROWTH
Table 1 and Figure 1 summaries the estimated household growth between 2020 and 2040 the resulted
from the process described in the prior section. Between 2020 and 2040 there is an expected total growth
of 33,312 households within the Tri-Valley Area. This equates to a 24 percent change or an annual growth
rate of 1.09%.

2.2.3 COMPARISON WITH 2008 NEXUS STUDY
A comparison of the total growth (base year to horizon year) and the annual growth rates between the 2008
Nexus Study and the 2020 Nexus Study forecast is presented in Table 8. The household growth estimated
in the current 2020 Nexus Study is approximately half as much as estimated in the 2008 Nexus Study. The
employment growth is estimated to be slightly lower than the 2008 Nexus Study. A slower build-out results
in smaller amount of development being available to pay towards improvement projects.

Table 11, Table 12, Figure 12, and Figure 13 presents a comparison of the employment growth between
2008 Nexus Study and the 2020 Nexus Study. All employment types except for Other are forecast to
experience less growth than anticipated in the 2008 Nexus Study. Retail and Other employment experience
higher growth at 15% and 8% more than 2020 estimate. For Agriculture employment, there was a -7%
difference. Service, manufacturing, and trading employment experienced the greatest difference, ranging
from -37% to -43% compared to employment numbers anticipated for 2020 in 2008 Nexus Study. While the
actual numbers differ from the anticipated growth assumed in 2008 Nexus Study, the 2020 Nexus Study is
anticipating similar growth trends as the previous study for all employment types.

3 IMPROVEMENT PROJECTS AND COST ESTIMATES
This chapter presents the 38 improvement projects included as part of the 2020 Nexus Updates.
3.1 IMPROVEMENT PROJECTS
There are 38 improvement projects that the TVTC has included in the Tri-Valley Transportation
Development Fee (TVTDF) for the 2020 Nexus Study. Of those projects, 15 projects exist in the current
TVTDF and 23 that are to be considered as part of this nexus update study.
3.1.1 CURRENT PROJECT LIST
Current projects are divided into two lists. The first list, List A, includes 7 projects that were included in the
original program adopted in 1995. The second list, List B, includes 8 projects that were included in the 2008
Nexus Study.
Out of the 27 existing projects, 10 projects have been completed and are no longer considered for further
funding. In addition, two projects (B-9 Danville Boulevard/Stone Valley Road I-680 Intersection and B-11a
I-680 HOV Direct Access Ramps) have been removed from the project list and are no longer being
considered for funding (for a total of 12 projects removed from the prior lists). The remaining projects have
not been fully completed. Table 13 summaries the projects in List A and B along with their total project
costs and their remaining unfunded cost. Detailed description of projects in Lists A and B are provided in
Appendix A.
3.1.2 NEW SELECTED PROJECT LIST
With almost half of the current project list completed and no longer receiving funding, TVTC reviewed and
selected additional projects to be considered for receiving funding from the TVTDF. This selection process
involved a comprehensive planning process to develop a project list that mitigates the impacts of new
development based on feasibility and stakeholder support. From this process, 23 additional projects (List
C) were identified to receive funding from the TVTDF. List C projects, along with their total project costs
and their remaining unfunded costs are listed in Table 14. Detailed descriptions of projects in List C are
provided in Appendix B.
3.2 UNFUNDED COST
Tables 13 and 14 presents total project cost and their remaining unfunded cost. The total investment for
projects eligible to receive TVTDF funding is estimated to be $4.470 billion, where $3.677 billion is
unfunded. An additional reduction was applied to account for external “cut-though” trips on roadway
congestion projects. Future development within the Tri-Valley area is not responsible to pay for these trips
since these trips are caused by growth outside of the Tri-Valley area. This reduces the total unfunded
cost to be covered by the maximum TVTDF to $2.928 billion. Note that this does not change the overall
project costs.
The funded amount includes the current TVTDF amount currently allocated toward projects as well as
additional federal, state, regional, or local funding sources. Based on input received from member
Tri-Valley Transportation Council │ 2020 Nexus Fee Update Study
August 2021 │ Final 20
jurisdictions, it is anticipated that approximately $793.24 million of funding has been identified for the current
project list. Appendices A and B include a cost estimate and a portfolio of likely funding sources.

4 NEXUS FINDINGS
This chapter presents the relationship of between the increase travel demand from new development, the
cost of improvements needed to accommodate that growth, and the impact fee to fund those investments.
4.1 OVERALL METHODOLOGY
Impact fees may be calculated using a purely technical method that would fund the cost of facilities required
to accommodate growth. The four steps followed in any development impact fee study include the following:
1. Prepare growth projections;
2. Identify facility standards;
3. Determine the amount and cost of facilities required to accommodate new development based on
facility standards and growth projections; and
4. Calculate the public facilities fee by allocating the total cost of facilities per unit of development.
This nexus study results in a calculation of the maximum fee based on the list of projects identified in
Chapter 3 (and described in Appendices A and B) to the greatest extent technically defensible under the
Mitigation Fee Act. Consistent with the TVTC’s directions, the full cost of funding these improvements is
used to calculate the maximum fee rates the TVTC could apply to all new residential and non-residential
development in the Tri-Valley between 2020 and 2040.
4.2 MITIGATION FEE AC T FINDINGS
Development impact fees are one-time fees typically paid when a building permit is issued and imposed on
development projects by local agencies responsible for regulating land use (cities and counties). To guide
the widespread imposition of public facilities fees, the State Legislature adopted the Mitigation Fee Act (Act)
with Assembly Bill 1600 in 1987 and subsequent amendments. The Act, contained in California Government
Code Sections 66000 through 66025, establishes requirements on local agencies for the imposition and
administration of fee programs. The Act requires local agencies to document five findings when adopting
a fee.
The five statutory findings required for adoption of the TVTC updated impact fee were adopted when the
first TVTC fee was adopted in 1995 and subsequently again when the Nexus Study was updated in 2008
and 2017. They are presented here and supported by the Nexus Analysis section (Chapter 2) of this report.
All statutory references below are to the Act. This sample framework for the Mitigation Fee Act findings is
only to provide local agencies with guidance and is not a substitute for legal advice. Local agencies will
customize the findings for their jurisdiction and consult with their legal counsel prior to adoption of the
updated TVTDF.
4.2.1 PURPOSE OF FEE
For the first finding, the local agency must identify the purpose of the fee (Section 66001(a)(1)). The TVTC
policy, as expressed through the TVTC Action Plan, is that new development shall contribute for mitigation
of their impacts on the Routes of Regional Significance, and that the cost sharing of recommended
improvements will be implemented through the TVTDF regional impact fee program. This is administered
by the seven jurisdictions of Alameda County, Contra Costa County, Dublin, Pleasanton, Livermore,
Danville, and San Ramon, which all signed a joint powers authority (JPA). The fee advances a legitimate
Tri-Valley Transportation Council │ 2020 Nexus Fee Update Study
August 2021 │ Final 23
public interest by enabling the TVTC to fund improvements to transportation infrastructure required to
accommodate new development.
4.2.2 USE OF FEE REVENUES
For the second finding, the local agency must identify the use to which the fee is to be put. If the use is
financing public facilities, the facilities shall be identified. That identification may, but need not, be made by
reference to a capital improvement plan, as specified in Section 65403 or 66002, may be made in applicable
general or specific plan requirements, or may be made in other public documents that identify the public
facilities for which the fee is charged (Section 66001(a)(2)). The TVTDF will fund expanded facilities on the
Routes of Regional Significance to serve new development. These facilities include the following:
• Roadway widening;
• Roadway extension;
• Traffic signal coordination and other traffic improvements;
• Freeway interchanges and related freeway improvements;
• Active transportation (pedestrian/bicycle) improvements;
• Safety improvements needed to mitigate the higher volume of traffic generated by new
development on a major arterial or other regional facility; and
• Improvements required for regional express bus and rail transit.
4.3 BENEFIT RELATIONSHIP
The nexus must show a reasonable benefit relationship between the fee’s use and the type of development
project upon which the fee is imposed. In other words, the nexus must demonstrate that the improvement
projects will mitigate the impacts of new development upon which the fee is imposed. This section describes
the methodology and results for establishing the benefit relationship.
4.3.1 METHODOLOGY
The previous 2008 Nexus Study used a model-based delay methodology to determine how List A and List
B would mitigate the impacts of new development by comparing vehicle hours of delay (VHD) from the
2005 base year with the Future 2030 No-build and Future 2030 Build scenarios. Given that some of the
new recommended projects cannot be effectively analyzed using this same methodology, additional
methodologies are being introduced as part of this update to appropriately assess the benefits of some
select projects.
To facilitate this approach, projects were aggregated into different improvement categories. These
categories include roadway capacity, transit, safety, pedestrian/bicycle, intersection, and technology. If the
project’s benefit could not be sufficiently analyzed based on model-delay, either because the project could
not be reflected in the model or that the model is insensitive to the benefits associated with a specific project,
the project was categorized as a safety, pedestrian/bicycle, intersection, or technology improvement and
accordingly analyzed using off-model techniques. Since these improvement categories improve different
aspects of the transportation system, differing methodologies and measures of effectiveness (MOEs) are
necessary to appropriately evaluate their anticipated benefit to the transportation system. It should be noted
some projects could be categorized into multiple improvement types; however, projects were limited to the
category which best reflects their primary benefit for the purposes of supporting this Nexus Study. Table

each project was categorized is included in Appendix C.

4.3.2 ROADWAY CAPACITY AND TRANSIT IMPROVEMENTS
Roadway capacity projects include improvements that involve increasing capacity such as widening a
roadway to add additional through lanes or extending existing roadways. Transit projects include
improvements that upgrade or expand existing transit service or assist with the implementation of new
transit routes and services. Both roadway capacity and transit improvement projects were evaluated based
on region wide delay derived using the CCTA travel demand model. Morning and evening region wide peak
hours of delay from the two future scenarios, 2040 No-Build (without improvement projects) and 2040 Build
(with improvement projects), were compared to the 2020 base year conditions.
The 2040 No-Build scenario is based on a year 2040 transportation network that will carry all of the locally
produced or attracted new trips, but that only includes improvements that are expected to be funded under
the financially-constrained RTP without the proposed Tri-Valley Transportation Development Fee projects
(List A, B, and C). The 2040 Build scenario is based on a year 2040 transportation network that includes
all the additional improvements that are expected to be funded with the updated Tri-Valley Transportation
Development Fee. Both the 2040 No-Build and 2040 Build project scenarios include all of the travel
associated with new development within the Tri-Valley. Under both scenarios, travel associated with
through trips was excluded from the resultant delay summary (i.e., trips that have origins and destinations
outside the Tri-Valley). Excluding through trips is common practice for this analysis given that the impact of
this travel is not generated by land uses within the Tri-Valley area and therefor assessing a fee is
impractical.
The improvement projects were evaluated using the aggregate regional peak-hour average weekday VHD
delay on all the significant roadways (includes freeways, expressways arterials, and major collectors) in the
Tri-Valley Transportation Council │ 2020 Nexus Fee Update Study
August 2021 │ Final 25
Tri-Valley on the 2020 Base Year networks and the 2040 No-Build and Build networks. The aggregate VHD
provide a reasonable system wide measure of the impact of new development on congestion and mobility.
According to the CCTA travel demand model, between 2020 and 2040, if no projects are undertaken, the
number of AM peak hours of delay is expected to increase 60 percent from 24,718 to 39,570 hours, while
the number of PM peak hours of delay is expected to escalate 88 percent from 15,613 to 29,376 hours. If
the projects are undertaken, the number of AM peak hours of delay would decrease 15 percent compared
to the 2040 No-Build scenario, whereas, the number of PM peak hour of delay would decrease 23 percent.
This modest improvement demonstrates that the proposed improvement projects only partially mitigate
future congestion by ne w development. Table 16 and Figure 14 show the comparison between the Future
2040 Build and Future 2040 No-Build scenarios.
In the aggregate, the comparison between the three scenarios showed that: 1) the 2020 Base Year
conditions are better than the Future 2040 No-Build conditions; 2) the Future 2040 Build conditions are
better than the Future 2040 No-Build; and 3) the Future 2040 Build conditions are not better than the 2020
Base Year conditions. These comparisons demonstrated that, in the aggregate, new development does not
fund infrastructure needed to address existing deficiency caused by existing development.

In addition to reducing VHD, many roadway capacity and transit projects include additional secondary
benefits to the transportation system. Many of these projects will result in safety benefits, as congestion
can often exacerbate unsafe motoring conditions. Additionally, specific project attributes such as modifying
interchanges or widening roadways to provide additional lanes so vehicles can safely maneuver along the
roadway or provide space for slower moving vehicles during peak times can also improve safety. Other
common project benefits may include pedestrian and bicycle improvements either directly or indirectly. For
example, interchange can often be barriers for bicycles and pedestrian, however several of the interchange
projects (e.g. C-12: Hacienda/I-580 Interchange Improvements and C-13: Fallon/El Charro Interchange
Improvements) include bicycle and pedestrian improvements which close existing gaps and encourage
more pedestrian and bicycle activity.
Based on this analysis it is determined that the planned projects identified in this report will expand the
capacity of the Routes of Regional Significance to accommodate the increased trips generated by new
development and thus, there is a reasonable relationship between the use of the fee for these projects and
the new development on which the fee will be imposed.
4.3.3 SAFETY IMPROVEMENTS
Safety projects involves safety-related improvements such as shoulder widening, installing guardrail,
installing median barriers, or realigning roadway. For these projects, a crash reduction factor was calculated
based on each safety improvements being implemented. The crash reductions were subsequently applied
to crash forecasts for the purpose of identifying future benefits. The safety improvements considered in the
evaluation are listed below:
• California Highway Patrol (CHP)
Enforcement Area
• Intersection
Improvement • Shoulder Widening
• Guard Rail Update • Roadway Median Barrier • Signal Timing Optimization
• Guardrails • Roadway Realignment • Speed Feedback Signs
• High Friction Pavement • Retaining Walls • Increased Super elevation
• Additional Turn Lanes
Each of the safety elements for the proposed improvements were converted to a total number of annual
crash savings in the region based on the Caltrans’ Local Roadway Safety Manual (LRSM) and Federal
Highway Authority’s (FHWA) Crash Modification Factors (CMF) Clearing House guide. CMFs are based on
before and after research of safety improvement implementations. They indicate the proportion of future
crashes that may be prevented by implementing a given countermeasure, reducing the crash frequency for
an intersection or roadway segment. In other words, a CMF is a multiplicative factor used to compute the
expected number of crashes after implementing a given countermeasure at a specific site.
The CMF was applied to a crash forecast which was based on 5-years of historical crash data which
resulted in fatality or injury. The reduction in crashes was then then converted to annual crash saving based
on Highway Safety Improvement Program (HSIP) crash saving dollar amounts shown in
Table 17.

Fatal $2,190,000
Serious $2,190,000
Moderate $142,300
Minor $80,900
Table 18 shows the overall annual crashes saving from traffic injuries that were potentially eliminated. Note
that this analysis excludes property costs and as such should be conservative. Also note that the forecast
only considers the effect of new traffic impacts and excludes the effect of existing conditions for the
purposes of establishing Nexus.

As shown in Table 19, there is a direct cost benefit to the investments made for roadway safety
improvements in the region. While it is difficult to estimate an absolute percentage in reduced peak hour
delays, the expected reductions in crashes will also enhance system reliability and resilience.
4.3.4 PEDESTRIAN/BICYCLE IMPROVEMENTS
While projects may include pedestrian and/or bicycle improvements, out of the 38 projects, project C-11
Iron Horse Trail Improvements is the only project that predominantly focuses on pedestrian and bicycle
improvements. Project C-11 consists of various improvements to the Iron Horse Trail within the TVTC
boundaries including overcrossing construction, closing existing gaps, and adding safety improvements
through the trail system. Pedestrian and bicycle improvement were evaluated based on NCHRP 552
Guidelines for Analysis of Investments in Bicycle Facilities. This approach relies on spatial analysis
techniques to determine the likely number of new active transportation users resulting from the introduction
of a new pedestrian/bicycle improvement. Table 19 shows the comparison between the Future 2040 Build
and Future 2040 No-Build scenarios.

Total Facility Users 2,006 2,817 5,415
Tri-Valley Transportation Council │ 2020 Nexus Fee Update Study
August 2021 │ Final 28
As shown in Table 19, Project C-11 could add over 2,500 bicycle trips per day on the Iron Horse Trail by
2040 which will provide an alternative to congested vehicular travel as well as significant health and
recreational value. Closing existing gaps in the trail will also encourage bicycle trips for other trip purposes
beyond just commute trips, including school, commercial and recreational trips.
Project C-11 improvements will result in additional secondary operational and safety benefits. Currently
many at-grade crossings are located at intersections with high vehicular, pedestrian, and bicycle volumes
which are regularly disrupted by conflicting at-grade operations given required traffic signal phasing. These
improvements will help improve vehicular traffic operations by relocating pedestrian and bicycle traffic away
from vehicular traffic helping to offset the transportation impacts associated with future development. These
improvements will also provide safety benefits by reducing the potential for vehicle-bicycle and vehicle-
pedestrian conflicts. Using the same methodology described in the previous section, a separate safety
analysis was conducted to quantify the safety benefits of all the C-11 project. Table 20 summarizes the
safety benefit for Project C-11.

4.3.5 INTERSECTION IMPROVEMENTS
There are two projects in List C with intersection improvements. Project C-4: Vasco Road & Dalton Avenue
intersection Improvements, includes the addition of a traffic lane, signal optimization, and other
improvements such as shoulder widening and roadway alignment to improve safety. Vasco Road is a major
commute corridor connecting the City of Livermore and City of Brentwood. The intersection at Dalton
Avenue provides access to the communities in the San Ramon Valley. With the planned and anticipated
residential and industrial development along the corridor, this intersection is expected to have significant
delays during the peak hours of commute.
Project C-8: Santa Rita and I-580 Interchange, will construct a second southbound left turn lane from Santa
Rita onto Pimilico Drive. The City of Pleasanton General Plan has identified this intersection to have a
reduced Level of Service under build out conditions.
4.3.6 TECHNOLOGY IMPROVEMENTS
There are two technology projects in List C. While Project C-10: Innovate 680 consist of multiple
components including transit infrastructure and service improvements, roadway improvements, and
technology enhancement, this project has been categorized as a technology improvement because TVTDF
funding is being requested only for the Advance Technology component of the project. Other project
components are expected to be funded through alternative sources. The Advance Technology component
consist of implementing three technology-related strategies to improve operation along the I-680 corridor.
Strategies include providing an enhanced 511 mobile app and implementing a shared autonomous vehicles
(SAV) program to shift travel away from single occupant vehicles by providing travelers with better
information about mode choice opportunities, resultant travel time, cost per trip, and the availability of
Tri-Valley Transportation Council │ 2020 Nexus Fee Update Study
August 2021 │ Final 29
transit. Other technology strategies include integrating adaptive ramp metering and/or corridor/incident
management systems which can help improve the efficiency and safety of the transportation system.
Project C-15: Technology Enhancements proposes to provide connectivity for transit and vehicles between
local arterials and regional facilities. The project is expected to be completed in three phases - Feasibility,
Design, and Construction. The TVTDF will help fund the feasibility study phase of the study, since the
details of the design and construction phase are unknown at this time. The feasibility study will focus on the
first and last mile connectivity opportunities at key transit hubs and along major transit routes in the Tri-
Valley area. Leveraging existing and emerging technology, such as connected and autonomous vehicles,
may help increase safety and mobility for all modes. These technologies may also help with increasing
transit ridership or expanding transit service to less-served areas, especially for communities that currently
lack service. Given that the resultant projects are intended to offset the impacts of future development, the
feasibility study is appropriate to include in the TVTC project list.
4.4 BURDEN RELATIONSHIP
The need for the TVTDF is based on the forecasted increase in congestion on routes of regional significance
as well as other transportation impacts resulting from new development. Consistent with the methodology
from the 2008, the contribution by each land use was based on the proportion of average AM/PM trips
generated by each land use. As demonstrated in this Study, there is a reasonable relationship between the
need for the planned projects and the types of development upon which the fee is imposed because the
planned projects will mitigate the transportation impacts of said new development.
4.4.1 TRIP RATE
The 2008 Nexus Study used the 7th Edition of Institute of Transportation Engineers (ITE)’s Trip Generation
Handbook to develop the trip rates for each land use category. Since then, three additional editions of the
Trip Generation Handbook have been published for use, ending with the most recent 10th Edition. It was
determined that for all categories except the ‘Other’ category, the trip rates would be developed using the
10th Edition rather than the 7th Edition for this update. In addition, consistent with the 2008 Nexus Study,
the trip rates were developed based on adjacent street traffic rather than peak -hour of generator. A 30-
percent reduction was also taken for retail trips to account for pass-by trips, consistent with the 2008 Nexus
Study. Table 21 below summarizes the comparison in average AM and PM peak-hour trip rates by land
use type. As shown in Table 21, every land use category results in a lower trip rate using the 10th Edition
when compared to the 7th Edition.

4.4.2 TOTAL TRIPS BY LAND USE
The total number of trips generated by the growth in either dwelling units or square-feet for each land use
category are shown in Table 22. As shown in Table 22, a total of 57,596 trip ends are generated by the
land use growth between 2020 and 2040. The growth attributable to single-family residential units generates
the largest number of trips, 13,716, or almost 25-percent of the total trips. The growth attributable to
industrial employment or industrial buildings generates the fewest number of trips, 6,178, or just over 10-
percent of the total trips.

4.5 FEE ESTIMATION
As required by the Mitigation Fee Act, the following section outlines the methodology for calculating the
proposed fee and demonstrates how there is a reasonable relationship between the amount of the proposed
fee and the cost of the public facility or portion of the public facility attributable to the development on which
the fees will be imposed.
The following steps were taken to determine the fee for each land use type:
1. Determine total unfunded cost.
2. Determine average AM/PM forecast peak-hour trips generated
3. Determine Fee per Land Use Category
4. Determine Maximum Fee
4.5.1 TOTAL UNFUNDED COST
The total investment for projects eligible to receive TVTDF funding is estimated to be $4.470 billion,
where $3.677 billion is unfunded. An additional reduction was applied to account for external “cut-though”
trips on roadway congestion projects. Future development within the Tri-Valley area is not responsible to
pay for these trips since these trips are caused by growth outside of the Tri-Valley area. This reduces the
total unfunded cost to be covered by the maximum TVTDF to $2.928 billion. Note that this not change the
overall project costs.
4.5.2 PEAK-HOUR TRIP FORECAST
Section 4.4.2. describes how the peak hour forecast was determined. Based on Table 22, an average of
57,596 AM/PM peak hour trips are generated by the land use growth between 2020 and 2040.

August 2021 │ Final 31
4.5.3 FEE PER LAND USE CATEGORY
To determine the total project cost by category, each land use category’s share of the total trips generated
by land use growth was multiplied by the total cost. An example calculation is shown below: 𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆 𝐹𝐹𝐹𝐹𝐹𝐹𝑆𝑆𝑆𝑆𝐹𝐹 𝑅𝑅𝑆𝑆𝑅𝑅𝑆𝑆𝑅𝑅𝑆𝑆𝑆𝑆𝑅𝑅𝑆𝑆𝐹𝐹𝑆𝑆=$𝑋𝑋𝑋𝑋𝑋𝑋 𝑀𝑀𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑀𝑀𝑆𝑆 × 13,716 𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆 𝐹𝐹𝐹𝐹𝐹𝐹𝑆𝑆𝑆𝑆𝐹𝐹 𝑅𝑅𝑆𝑆𝑅𝑅𝑆𝑆𝑅𝑅𝑆𝑆𝑆𝑆𝑅𝑅𝐹𝐹𝑆𝑆𝑆𝑆 𝑇𝑇𝑇𝑇𝑆𝑆𝑇𝑇𝑅𝑅57,596 𝑇𝑇𝑇𝑇𝑅𝑅𝐹𝐹𝑆𝑆 𝐴𝐴𝐴𝐴𝑆𝑆𝑇𝑇𝐹𝐹𝑅𝑅𝑆𝑆 𝑇𝑇𝑇𝑇𝑆𝑆𝑇𝑇𝑅𝑅 =$𝑋𝑋𝑋𝑋𝑋𝑋 𝑀𝑀𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑀𝑀𝑆𝑆
The total cost by land use category is shown in Table 23. As shown in Table 23, the total cost ranges from
$396.27 million for industrial uses to $879.78 million for single-family residential uses.

4.5.4 MAXIMUM FEE
To determine the maximum fee per dwelling unit, square-foot, or trip depending on the land use category,
the total cost per category was divided by the total number of units, square-feet, or trips that occur between
2020 and 2040. An example calculation is shown below 𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆 𝐹𝐹𝐹𝐹𝐹𝐹𝑆𝑆𝑆𝑆𝐹𝐹 𝑅𝑅𝑆𝑆𝑅𝑅𝑆𝑆𝑅𝑅𝑆𝑆𝑆𝑆𝑅𝑅𝑆𝑆𝐹𝐹𝑆𝑆=$𝑋𝑋𝑋𝑋𝑋𝑋 𝑀𝑀𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑀𝑀𝑆𝑆15,857 𝐷𝐷𝐷𝐷𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆 𝑈𝑈𝑆𝑆𝑆𝑆𝑅𝑅 =$𝑋𝑋𝑋𝑋𝑋𝑋 𝑝𝑝𝑆𝑆𝑝𝑝 𝑅𝑅𝐷𝐷𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆𝑆 𝑢𝑢𝑆𝑆𝑆𝑆𝑅𝑅
The maximum fees are summarized in Table 24. As shown in Table 24, the maximum fee for a single-
family residential unit is $43,397 while the maximum fee for one square-foot of retail use is $84.52.
Historically the TVTC has not applied the maximum fee schedule. For both the 1995 and 2008 nexus
studies, the TVTC jurisdiction set rates at approximate one-third of the maximum fee calculated in the 1995
and 2008 Nexus studies to help foster growth within the Tri-Valley area, while providing a regional funding
source that could be used to match and help compete for Federal and State transportation grants and
funding programs.

5 NEXT STEPS
This report documents the findings needed to adopt a fee schedule to fund the improvements projects
elected to receive funding from the TVTDF. Below are next steps needed for the TVTC to adopt a fee
schedule that is most appreciate for their needs.
5.1 ADJUSTMENT TO MAXIMUM FEE CALCULATION
As previously discussed, the maximum fee would generate sufficient revenues to fund the total unfunded
cost of all selected projects. However, if the TVTC adopts fee schedule below the maximum, this would
result in revenue shortfall and TVTC would need to take one or both of the following actions:
• Increase funding from other sources
• Fund selected projects or project phases
5.1.1 INCREASE FUNDING FROM OTHER SOURCES
TVTC could reduce the funding shortfall for specific projects by increasing funding form other federal,
state, regional, and local fund sources. Some potential funding sources as listed below:
• Federal
o One Bay Area Grant Program (OBAG)
• State
o State Transportation Improvement Program (STIP)
o Senate Bill 1 (SB 1)
o Office of Traffic Safety (OTS) Grant
o Active Transportation Program (ATP)
• Regional
o Transportation Fund for Clean Air (TFCA) County Program Manager (CPM) Fund Local
o Measure B & Measure BB
o Measure J
• Local
o Traffic Impact/Mitigation Fees
o Development Fees
o General Purpose Funds
5.1.2 FUND SELECTED PROJECTS OR PROJECT PHASES
TVTC could determine to fund the full amount for selected projects or fund certain phases of the project
such as the planning or design phase of a project.
5.2 UPDATE STRATEGIC EXPENDITURE PLAN (SEP)
Once the final fee schedule has been adopted TVTC should update the SEP to set priority for which
projects should be funded first.

A -11. EXPRESS BUS/BUS RAPID TRANSIT (BRT) – PHASE 2
TVTC Project Sponsor: City of Dublin
Lead Agency: Livermore Amador Valley Transit Authority (LAVTA)
Project Description: Project A-11 is Phase 2 of the Express Bus/BRT, which consists of two phases. The
express bus route associated with Phase 1 of the project has been operating since January 2011.
Phase 2 includes upgrades to and expansion of the initial Rapid Project, as well as some project
refinements, updates, and maintenance/replacement of original project elements and equipment based on
evaluation of the existing components and conditions at the time of funding. The transit system priorities
include the following elements:
• A technologically advanced transit system
• A multi-modal transportation system that supports the local economy
• Prioritized regional transfers and connections
• Reliability and efficiency that maximizes value to taxpayers and the community
Phase 2 will consist of five key potential elements (based upon conditions at time of funding):
1. Advanced Technology – Design and installation of advanced technologies and road features
allowing rapid transit to operate quickly and efficiently, and help to mitigate delay in dwell times,
boardings, and travel times. Some of the advanced technologies and road features that LAVTA is
considering for Phase 2 are: transit signal priority (TSP), enhanced stations, queue jumps,
environmentally friendly coaches and advanced onboard technology, advanced fare collection
systems, level boarding, dedicated travel lanes, and better integrated park and ride facilities and
transit centers. Element 1 is currently budgeted at $2 Million.
2. North/South Express Bus/Rapid Service – In keeping with the Alameda Countywide Transit
Plan, and in order to provide a strong foundation for LAVTA’s System, I-680 service expansion,
North/South Express Bus/BRT service, and other Express/Rapid service options, will be explored
and considered. Element 2 is currently budgeted at $6.5 Million.
3. Dublin Extension – Continued study and planning will be done on how best to integrate the
planned extension of Dublin Boulevard and the planned Livermore BART Extension into LAVTA’s
Express Bus/BRT service. Element 3 is currently budgeted at $6.5 Million.
Tri-Valley Transportation Council │ 2020 Nexus Fee Update Study

4. Pleasanton Alignment – Complete “Rapidization,” of the Livermore to Pleasanton alignment will
be evaluated, with advanced technology and improved service elements planned for the south side
of I-580, and possible connection to the existing Rapid service. Element 4 is currently budgeted at
$1.5 Million.
5. Park and Ride Lots – In working with local cities and Alameda County, LAVTA will consider
improved park and ride elements to support bus, biking, and walking access in the Tri-Valley, and
to improve the accessibility of transportation alternatives that would ease congestion on I-580.
These options might include: construction of new lots, smart signage, improved bicycle storage,
increased pedestrian accessibility and safety, enhanced multi-modal elements on coaches, and
increased or revised bus service to rail stations and regional transit connections. Element 5 is
currently budgeted at $2 Million.
Status: Phase 1 is fully completed and operational, as of January 2011. Phase 2 is in the research, design,
and planning stage. In August 2016, LAVTA realigned the Express Bus/BRT Route (Route 30R) to serve
Las Positas College, and transformed existing Route 10 into an Express Bus/BRT (Route 10R) operating
through Pleasanton to BART. The transformation of Route 10 into Route 10R was the first step in
implementation of the Phase 2 Pleasanton Alignment. LAVTA intends to implement additional items from
Phase 2 (Advanced Technology) to both Routes 10R and 30R in 2017, which includes upgrading the traffic
signal priority onboard the buses and at key intersections along both Rapid routes. Costs for Phase 2 have
been updated to reflect current pricing for the project elements listed above. Phase 2 Scope of work,
schedule, and full funding parameters are not known at this time.

C-11C IRON HORSE TRAIL CROSSING AT DUBLIN BOULEVARD
TVTC Project Sponsor: Dublin
Project Description: This project will build a bicycle and pedestrian bridge over Dublin Boulevard in order
to connect two segments of the Iron Horse Trail. This bridge will create a total separation between vehicles
and bicyclists/pedestrians. This will eliminate the possibility of motorized vehicles and pedestrians having
a collision, making this segment of the road safer for all users. Along with this, congestion will be reduced
as cars will no longer have to wait for pedestrians. This reduction of congestion will also allow for the transit
to operate more efficiently. Pedestrians and bicyclists will also not have to wait for a walk signal since they
will be able to continue their walk or ride without stopping.
The bridge will follow ADA requirements so that disabled people will be able to use it as well. This bridge
will also be aesthetically pleasing in order to attract users and improve the user’s experience. The bridge
will also connect BART to Dublin in a safe manner, encouraging recreational user of the Iron Horse Trail
and the opening of local businesses. This safe and fast route of crossing the Iron Horse Trail will promote
walking and bicycling for both recreational and commuting purposes in Dublin, this encouraging the shift
from motorized vehicles to alternative forms of transportation.
Status: The project is currently in the final design phase. Additionally, Environmental Analysis of the
project is currently in-progress.

C-11G IRON HORSE TRAIL BICYCLE/PEDESTRIAN OVERCROSSING –
TOWN OF DANVILLE
TVTC Project Sponsor: Danville/CCC/CCTA
Project Description: The Iron Horse Trail (IHT) is an 18-mile regional non-motorized trail that runs
north/south through the San Ramon Valley providing critical access to adjacent land uses. The construction
of overcrossings at key locations will develop attractive travel alternatives for congestion relief for commute
trips as well as better facilities for school, shopping, and recreations trips. For the scope of this project, the
proposed overcrossing location is Bollinger Canyon Road. At this location, the overcrossing will provide
substantial benefits including:
1. Improve safety by eliminating conflicts between pedestrians, bicyclists, and motorists;
2. Improve motor vehicle circulation by removing the at-grade crossings;
3. Reduce and eliminate unsafe crossing maneuvers by pedestrians and bicyclists;
4. Enhance safety by providing an environment that encourages walking and bicycling along the
Iron Horse Regional Trail; and
5. Increase trail usage by improving the connectivity at the Bollinger Canyon Road and Crow
Canyon Road crossings.

C-11H IRON HORSE TRAIL SYSTEM-WIDE IMPROVEMENTS
TVTC Project Sponsor: Contra Costa County, Town of Danville, City of San Ramon, Alameda County,
City of Dublin, City of Livermore, and City of Pleasanton
Project Description: As the primary regional multi-modal corridor between Contra Costa and Alameda
County, the Iron Horse Trail is the spine for active modes of travel in the East Bay. The proposed project
for the Iron Horse Trail includes safety, operational, and capacity improvements within the TVTC boundary
from Alamo to Livermore. The proposed project and associated cost estimate includes safety improvements
at roadway crossings, a proposed parallel path to separate users according to speed, and a buffer between
users traveling at high or low speed. The improvements would include features such as passive detection
at road crossings, actuated flashers or warning signals at roadway crossings, high visibility markings, minor
grading, construction of a new 10 foot wide parallel asphalt path with shoulders, and a buffer between high
and low speed corridors which may include vegetation or fencing to maintain safe separation. Other safety
improvements may be necessary to fit site conditions and as determined through additional study.

C-16 I -680 EXPRESS BUS SERVICE
TVTC Project Sponsor: Alameda CTC, in partnership with CCTA
Project Description: This project proposes to construct capital improvements and purchase buses in order
to establish an express bus service on I-680. This project requires the construction of the I-680 Express
Lane Gap Closure project, closing the gap in the express lanes between Alcosta Blvd and State Route 84,
in order to utilize the express lanes to avoid congestion, reduce travel time, and improve reliably, as part of
an express bus service between the Tri-Valley communities and Silicon Valley. This express bus service
would likely be combined with and become part of similar efforts by Contra Costa Transportation Authority
(CCTA) and their Innovate 680 program, with the intent to serve the entire I-680 corridor extending from
Martinez to San Jose, utilizing buses to provide access to additional commute options, including BART,
Amtrak, Caltrain, VTA light rail, local bus service, and Greyhound, for those living along the corridor.
The service would operate weekdays only, with proposed 20-minute headways during peak periods and
one-hour headways during off-peak hours. The service would be bi-directional to avoid substantial
deadhead time and to maintain a high level of service. New electric buses would be purchased as part of
this project.
Tri-Valley Transportation Council │ 2020 Nexus Fee Update Study
August 2021 │ Final 65
The project proposes to place express bus stops in the Tri-Valley area at the West Dublin/Pleasanton BART
Station and at a future park and ride to be constructed at the Bernal Avenue interchange in Pleasanton.
Understanding that the express buses must merge across all lanes of traffic to access the express lane,
these stop locations are spaced to efficiently serve the Tri-Valley area while also maximizing the express
lane distance the bus is able to utilize in-between bus stops.
The estimated costs below assume that at each bus stop location there would be construction of roadway
and bus stop improvements, including installation of transit amenities such as shelters, bike lockers,
lighting, and real time information signs.

Subject: TVTC SEP 2021 Update – AB 602 Supplemental Analysis
As the 2020 TVTC Nexus Study was adopted in August of 2021, prior to the implementation of
Assembly Bill 602 (AB 602), the Nexus Study and its resultant fee program is not subject to its
requirements. However, TVTC has undertaken this supplemental analysis to guide future analysis
requirements and to help inform the TVTC how AB 602 may impact the program when the next Nexus
Study update1 is completed. This analysis was approved by TVTC Board on April 18, 2022.
Background
Assembly Bill 602 (AB 602)
Assembly Bill 602 was approved and signed into law on September 28, 2021. Among other things,
this bill requires that impact fee nexus studies adopted on and after January 1, 2022 must, as
appropriate, identify the existing level of service, the new level of service, and include an explanation
as to why the new level of service is necessary for each public facility included in an impact fee
program. It should be noted that the basis for the required level of service analyses is not specifically
defined in AB 602 and that as a practical matter, level of service methods applied to various public
facilities need to vary depending on the type of facility being analyzed and the information available.
AB 602 also requires that studies adopted after July 1, 2022 either calculate a fee levied or imposed
on a housing development project proportionately to the square footage of the proposed units, or
make specified findings explaining why square footage is not an appropriate metric to calculate the
fee.
2020 Nexus Study
The performance analysis conducted in support of the 2020 TVTC Nexus Study analyzed the benefits
of proposed projects in the aggregate based on specific improvement categories. This aggregate
approach is an industry-accepted method when evaluating project impacts on a regional, system-
wide basis. This method is especially appropriate where a fee program is targeted to regional
improvements, as is the case with TVTC’s fee program. These categories included roadway
capacity, transit, safety, pedestrian/bicycle, intersection, and technology. Since these improvement

categories improve different aspects of the transportation system, differing methodologies and
measures of effectiveness (MOEs) were necessary to appropriately evaluate their anticipated benefit
to the transportation system. It should be noted that some projects have multiple beneficial project
elements and thus could be analyzed using more than one analysis technique (i.e., a project can
have both a congestion benefit and a safety benefit). However, for the purposes of this analysis,
project analysis was limited to the basis which best reflects the primary benefit and/or purpose of the
project.
Level of Service Analysis
Methodology
Table 1 summarizes the methodology and measure of effectiveness (MOE) that was used to evaluate
existing and future conditions for public facilities included within the 2020 TVTC Nexus Study. As
described in the prior section, the methodology and MOE selected were dependent on the type of public
facility being analyzed and the data available.

Roadway Capacity
Analysis of roadway capacity projects was completed based on the HCM concept of Level of Service
(LOS). The HCM LOS for a roadway facility is a qualitative measure used to describe operational
conditions. LOS ranges from LOS A (free flow traffic with minimal delay) to LOS F (heavy congestion
operating near or over capacity). As discussed in the following sections, Freeway, State Route, and
Interchange projects were evaluated using methodologies defined in the HCM 6th Edition, while
arterial roadway analyses were completed based on a volume/capacity (V/C) methodology commonly
applied for project analyses undertaken by the Alameda County Transportation Commission (ACTC).

For existing conditions, AM (7-9) and PM (4-6) peak period traffic volumes were obtained from the
Caltrans Traffic Census Program2 or recent publicly accessible traffic studies conducted within the
Tri-Valley area. These traffic counts were then evaluated to determine the highest AM and PM peak
hours of traffic which is the basis of the analysis contained herein. Future 2040 No Build and 2040
Build peak hour volumes were developed using post-processed data from a version of the CCTA
travel demand model updated to reflect input from the TVTC member jurisdictions. Further
information on the travel demand model’s development is provided within the 2020 TVTC Nexus
Study. Generally speaking, forecast volumes were developed using the “difference method”, which
involves adding forecasted traffic growth (future minus existing estimated traffic volumes from the
travel demand model) to an existing count.
In cases where a project is proposing a new roadway segment (C-4 Dublin Boulevard – North
Canyons Parkway Extension and C-5 El Charro Road Widening), a parallel roadway segment was
used as the basis for evaluating project need.
A minimum level of service standard of LOS F was used for roadway analyses.
Freeway
Freeway facilities were analyzed using the HCM 6th edition methodology for basic freeway segments.
As shown in Table 2, LOS is determined based on the density of traffic flow.

Arterial
Alameda County Transportation Commission (ACTC) and Contra Costa Transportation Authority
(CCTA) evaluate arterials using different methodologies. ACTC’s methodology is based on volume-
to-capacity (v/c) ratios while CCTA evaluates arterials based on intersection level of service. This
analysis was evaluated based on the ACTC methodology given the nature of the analysis
requirements. During the design phase of a project, it is anticipated that more detailed operational
analysis will be completed.
Arterial level of service analysis assumed a per-lane capacity of 800 vehicles per hour. The LOS
criteria shown in Table 4.

1 For All-way stop-control intersection (AWSC), LOS is defined based on average intersection delay. For side-street stop-
controlled intersections (SSSC), LOS is defined based on the worst movement delay.
Source:Highway Capacity Manual, 6th Edition
Transit
Transit projects were evaluated based on service frequency LOS from the Transit Capacity and
Quality of Service Manual (TCQSM)under which LOS criteria varies depending on the type of transit
service. As shown in Table 6, LOS for urban scheduled transit service3 is determined on headway or
the time between buses/trains. For intercity schedule transit services, commuter or express buses,
LOS is determined on the number of trips provided each day.
For this analysis, all transit projects were evaluated on the basis of the urban scheduled transit
service LOS criterion as the projects are anticipated to operate throughout the day on a fixed
schedule. A level of service standard of LOS F was used for this analysis. In addition, other benefits
such as increases in ridership, as well as resultant system-wide VMT reductions may also be
evaluated.
Safety
The number of crashes per million vehicle miles travelled (crash/M-VMT) were calculated for the
project segment based on the observed number of crashes within 5 years. The number of crashes for
the future no build conditions were estimated based on the Safety Performance Functions (SPF)
described in Highway Safety Manual (HSM) 2010. SPFs are regression equations that estimate the
average crash frequency for a specific site type as a function of annual average daily traffic and the
segment length. The reduction in crashes in the Future 2040 Build scenario were calculated by
applying Crash Modification Factors (CMF) based on proposed safety improvements for each project.
For the purposes of this study and based on the observed data reviewed, a threshold designation
was established for crashes per million-VMT of more than 1.
3 Urban schedule transit service includes all scheduled service within a city, as well as service
between cities within a larger metropolitan area.

Pedestrian / Bicycle
Pedestrian / Bicycle improvements were evaluated using the modified level of traffic stress (LTS)
methodology used in the Montgomery County Bicycle Master Plan4 in Maryland. This methodology is
based on the original LTS methodology developed in 2012 by the Mineta Transportation Institute and
San Jose State University5. Both methodologies assign a traffic stress level base on street/traffic
attributes (e.g. traffic speed, traffic volume, number of lanes, etc.). As shown in Table 7, the original
LTS has four stress levels, while the Montgomery County methodology provides three additional
stress levels. The Montgomery County methodology also includes criteria for separated bikeways,
two-lane roads, and industrial streets. For the purpose of this analysis, a threshold of LTS 4 was
used.

Intersection
Intersection improvements were evaluated using the HCM intersection methodology. As shown in
Table 5, intersection LOS is based on delay. Existing AM (7-9) and PM (4-6) traffic volumes were
obtained from recent publicly accessible traffic studies. Future 2040 No Build and 2040 Build volumes
were developed based on the “difference method” previously described. A level of service standard of
LOS F was used for this analysis.
Technology
Technology projects included in the 2020 TVTC Nexus Study include studies to evaluate and identify
potential technology-based solutions. Since these are studies and not public facilities, no MOE or
Page 8

thresholds were established at this time. AB 602 acknowledges that level of service analysis is not
possible for certain types of projects. However, a qualitative assessment was conducted to determine
how the technology being studies may result in delay or congestion reduction to offset the impacts
related to future growth.
Results
This section presents a summary of results for each project.
Roadway Capacity
Freeway
Freeway analysis was used to evaluate the following projects:
· B-1 I-580/I-680 Interchange (westbound to southbound)
· C-3 Dublin Boulevard – North Canyons Parkway Extensions
· C-7 I-680 Express Lanes – Hwy 84 to Alcosta
Project B-1 evaluated multiple segments along I-580 and I-680. In the existing conditions, these
segments operated at LOS D or LOS F. Even though some segments continue to operate at LOS F
with the Project in 2040, there will be a reduction in volume-to-capacity ratio (v/c).
Even though Project C-3 is a local roadway, the I-580 segment between Fallon Road and Airway
Boulevard was analyzed because the Dublin Boulevard-North Canyon Parkway extension would
divert local traffic from this freeway segment. In existing condition, the I-580 segment between Fallon
Road and Airway Boulevard operates at an unacceptable LOS F. Even though some segments
continue to operate at LOS F with the Project in 2040, there will be a reduction in v/c.
For Project C-7, future development will increase congestion along I-680 and will improve with the
construction of the project.
State Route
State Route analysis was used to evaluate the state route portion (SR-84/Isabella Avenue) of
Projects A-2b SR 84/I-580 Interchange.Future development will change the LOS from LOS B or
better in existing condition to LOS C through LOS E in 2040 No Build condition. Project A-2b will
improve LOS to LOS B or better.
Arterial
Arterial analysis was used to evaluate the following projects:
· A-2b SR 84/I-580 Interchange
· B-6 Jack London Boulevard Extension
· C-5 Camino Tassajara/Tassajara Road Widening Project (East of Blackhawk Drive to North
Dublin Ranch Drive)
· Roadway capacity portion of Project B-8 El Charro Road Widening
Page 9
kimley-horn.com 4637 Chabot Dr., Suite 300, Pleasanton, CA 94588 925-398-4840
Project A-2b evaluated Portola Avenue along the I-580 overpass. This segment operates at LOS F in
existing and 2040 No Build conditions. Project A-2b will improve operations to acceptable levels of
service.
Project B-6 evaluated Jack London Boulevard, east of El Charro Road. This segment operates at
LOS F in the existing and 2040 No Build conditions. With the project, Jack London Boulevard may
continue to operate at LOS F; however, there will be a reduction in v/c.
For Project B-8, future development will increase congestion along Camino Tassajara and will cause
the roadway to operation at LOS F in 2040 No Build conditions. Project B-8 will improve operations to
acceptable levels.
Since Project C-5 will extend El Charro Road south of Stoneridge Road/Jack London Boulevard, a
parallel route along Santa Rita Road was analyzed. Future development will increase congestion
along Santa Rita Road and will cause the roadway to operate at LOS F. Project C-5 will improve
operations to acceptable levels.
Interchange
Interchange analysis was used to evaluate the following projects:
· B-3 I-580/First Street Interchange Modification
· B-4 I-580/Vasco Road Interchange Modification
· B-5 I-580/Greenville Road Interchange Modification
· C-6 Sunol/680 Interchange Improvements
· C-9 Stoneridge/I-680 Interchange
· C-12 Hacienda/I-580 Interchange Improvements
· C-13 Fallon/El Charro Interchange Improvements
For Project B-3, the I-580/First Street interchange operates at LOS C or better in the existing
condition. Future development will increase the delay at the interchange. Project B-3 will reduce delay
compared to 2040 No Build conditions.
For Project B-4, the I-580/Vasco Road interchange operates at LOS E or better in the existing
condition. Future development will cause this interchange to operation at LOS F in the PM peak.
Project B-4 will improve operations to acceptable levels of LOS C or better.
For Project B-5, the I-580/Greenville Road interchange operates at LOS E or better in the existing
condition. Future development will cause this interchange to operate at LOS F in PM peak. Project B-
5 will improve operations to acceptable levels of LOS E or better.
For Project C-6, the I-680/Sunol Boulevard interchange operate at LOS F in the existing and 2040 No
Build conditions. Project C-6 will improve operations to acceptable levels of LOS B or better.

kimley-horn.com 4637 Chabot Dr., Suite 300, Pleasanton, CA 94588 925-398-4840
For Project C-9, the I-680/Stoneridge Drive interchange operates at LOS B in the existing condition.
Future development will increase delay at the interchange. Project C-9 will reduce delay compared to
2040 No Build conditions.
For Project C-12, the I-580/Hacienda Drive interchange operates at LOS C or better in the existing
condition. Future development will increase delay at the interchange. Project C-12 will improve
operations compared to 2040 No Build conditions.
For Project C-13, the I-580/Fallon Road interchange operates at LOS A or better in the existing
condition. Future development will increase delay at the interchange. Project C-13 will improve
operations compared to 2040 No Build conditions.
Transit
Transit projects include the following projects:
· A-11 Express Bus/Bus Rapid Transit (BRT) – Phase 2
· C-14 Valley Link Rail (Phase 1
· C-16 I-680 Express Bus Service
For Project A-11, both 10R and 30R routes have 15-minute headways (LOS C) in the existing
condition. Without the improvements proposed in Project A-11, congestion from future development
may increase the headway for these routes. Improvements proposed in Project A-11, such as transit
signal priority, queue jumps, dedicated travel lanes may allow 10R and 30R to operate more quickly
and efficiently.
Project C-14 would construct new stations and a transit line, so there is no LOS for existing or 2040
No Project conditions. It is anticipated that Valley Link would operate on similar headways as BART
which is 15 minutes in the AM peak and 20 minutes in the PM peak, which equates to LOS C. In
addition, the Valley Link EIR reports a 0.3% reduction in average weekday VMT between No Build
and Build condition.
Project C-16 would establish a new express bus service, so there is no LOS for existing or 2040 No
Project conditions. It is currently proposed that the bus would run on 20-minute headways during the
peak period, which equates to LOS C.

Technology
There are two technology projects: C-10 Innovate 680 and C-15 Technology Enhancements. Since
these are studies and not public facilities, no MOE or thresholds were established at this time. However,
a qualitative assessment was conducted to determine how the technology being studied may result in
delay or congestion reductions or other benefits.
Project C-10 Innovate 680 consists of multiple components including transit infrastructure and service
improvements, roadway improvements, and technology enhancement, this project has been
categorized as a technology improvement because TVTDF funding is being requested only for the
Advance Technology component of the project. Other project components are expected to be funded
through alternative sources. The Advance Technology component consists of implementing three
technology-related strategies to improve operation along the I-680 corridor. Strategies include providing
an enhanced 511 mobile app and implementing a shared autonomous vehicles (SAV) program for first
and last mile connectivity and access at Mobility Hubs, to shift travel away from single occupant vehicles
by providing travelers with better information about mode choice opportunities, resultant travel time,
cost per trip, and the availability of transit. Other technology strategies include integrating adaptive
ramp metering and/or corridor/incident management systems which can help improve the efficiency
and safety of the transportation system.
Project C-15 Technology Enhancements proposes to provide connectivity for transit and vehicles
between local arterials and regional facilities. The project is expected to be completed in three phases
- Feasibility, Design & Construction. The TVTDF will help fund the feasibility study phase of the study,
since the details of the design and construction phase are unknown at this time. The feasibility study
will focus on the first and last mile connectivity opportunities at key transit hubs and along major transit
routes in the Tri-Valley area. Leveraging existing and emerging technology, such as connected and
autonomous vehicles, may help increase safety and mobility for all modes. These technologies may
also help with increasing transit ridership or expanding transit service to less-served areas, especially
for communities that currently lack service. Given that the resultant projects are intended to offset the
impacts of future development, the feasibility study is appropriate to include in the TVTC project list.
AB 602 Proportional Allocation
Future development is responsible for paying for its proportional use of public facilities, rather than
the full unfunded cost of projects. Under AB 602s project-specific analysis methods , the proportional
allocation of costs for certain projects under the 2020 TVTC Nexus Study would be lower.ܣܤ 602 ܲݎݎݐ݈݅݊ܽ ܣ݈݈ܿܽݐ݅݊ %=2040 ܰ ܤݑ݈݅݀ ܩݎݓݐℎܧݔ݅ݏݐ݅݊݃ ܸ݈ݑ݉݁
