SPECIFIC REQUEST(S) OR RECOMMENDATION(S) & BACKGROUND AND JUSTIFICATION
RECOMMENDATIONS
Approve the following comments on the Draft Regional Transportation Mitigation Program
(RTMP) for transmittal to TRANSPAC:
- The RTMP requirement should only be evaluated for development projects that generate a
net increase of more than 100 peak hour trips, consistent with existing Measure C-1988
Growth Management Program requirements for traffic studies of local impacts.
- The RTMP requirement should only be evaluated for Regional Routes that have a
signalized intersection impacted by 50 or more interregional peak hour trips, consistent
with existing Measure C-1988 Growth Management Program requirements for traffic
studies of local impacts.
- The RTMP should be revised to clarify that an increase in interregional trips alone does
not require an inter-jurisdictional agreement(s), but that such agreements are only
triggered if the traffic increase is substantial in relation to the existing traffic load and
capacity of the Regional Route.
FISCAL IMPACT
None directly to the General Fund. A RTMP for Central County would imp se n additional cost

Report on Draft Regional Transportation Mitigation Program for Central ,County 5D,,)-

on development in the unincorporated areas of Central County. Funds generated from the Program would be
used for specified transportation improvements in Central County.
BACKGROUND/REASONS FOR RECOMMENDATIONS
The Contra Costa Transportation Authority (Authority) has requested each of the four regional transportation
planning committees to develop regional transportation mitigation programs (RTMPs) so that new
development will "pay its way" and not create unmet demand for transportation facilities. TRANSPAC, the
transportation planning committee for the central region of Contra Costa, has developed a draft RTMP for
review by participating jurisdictions (see Exhibit A). TRANSPAC will review the comments from each
jurisdiction to develop a RTMP for adoption by TRANSPAC and local jurisdictions which will fulfill a
requirement of the Measure C-1988 Growth Management Program.
Proposed RTMP Requirements
The draft program creates a requirement for an inter-jurisdictional agreement to mitigate traffic impacts
should a proposed development meet or exceed the established interregional trip threshold for Routes of
Regional Significance.
An interregional trip is defined as any trip outside the "home" jurisdiction in which the development is
located.
RTMP requirements are triggered if a development project generates 50 interregional trips in any one hour on
a Regional Route as defined in the Authority's Comprehensive Countywide Transportation Plan. TRANSPAC
jurisdictions are required to execute a developed-sponsored mitigation agreement with any TRANSPAC or
other jurisdiction determined to be impacted by the proposed development project. Such a development
project will be responsible for mitigating its proportionate share of impacts via an inter-jurisdictional
agreement(s).
The required California Environmental Quality Act (CEQA) assessment for a development project is to be used
to determine if impacts on a Regional Route need to be mitigated. The agreement will be developed in
cooperation with affected jurisdictions and are to include the identification, implementation and monitoring
mechanisms(s) for mitigation of impacts.
Concerns of County Staff
The RTMP appears to require traffic studies of development projects not typically covered under current
Measure C-1988 requirements. Presently, the Growth Management Program requires a traffic study for any
project that generates a net increase of more than 100 peak hour trips. Conceivably, under the RTMP,
projects that generate 100 or fewer peak hour trips would require a traffic study to determine if 50 or more
peak hour trips occur on a Regional Route outside the "home" jurisdiction. It would be more appropriate to
determine if the RTMP requirement is triggered as part of our current traffic studies conducted pursuant to
Measure C-1988. Such studies would determine if the threshold of 50 interregional peak hour trips is
exceeded by the development project on any Regional Route.
The RTMP appears to require an evaluation of mitigation measures at locations not typically required under
current Measure C-1988 requirements. Presently, the Growth Management Program requires traffic studies
to evaluate any signalized intersection where 50 or more peak-hour trips are added by a development project.
Conceivably, under the RTMP, a traffic study would need to evaluate mitigation measures at any Regional
Route location that receives 50 or more interregional trips, even if these trips exit the Regional Route before
crossing any signalized intersection location. This could include sections of Regional Routes that only have
unsignalized intersections or right-turn-in/right-turn-out intersections.
The requirement for an inter-jurisdictional agreement(s) appears to be intended to address impacts associated
with environmental thresholds. However, certain sections of the RTMP suggest that exceeding the
interregional trip threshold on a Regional Route by itself is an impact that must be mitigated. Increases in
traffic alone do not create a significant adverse traffic impact (see the first sentence in the proposal). Such
impacts occur only if the traffic increase is substantial in relation to the existing traffic load and capacity of
the street system. In some cases, 50 additional trips may be a significant, at other locations it may not. The
intent of the RTMP would be clearer if it defined when an impact is significant and requires consideration of
mitigation. For instance, a significant adverse traffic impact from a project could be defined as an
exceedance of the Traffic Service Objective for a Regional Route.

Dear Mayor Cooper:
TRANSPAC,the Regional Transportation Planning Committee for Central Contra Costa, is requesting the
assistance of your jurisdiction in the development of a Regional Transportation Mitigation Program (RTMP).
The RTMP is required by the Contra Costa Transportation Authority (C(-,fA) as part of each jurisdiction's
compliance with the Measure C Growth Management Program.
TRANSPAC has developed the attached draft RTMP for review by your jurisdiction. Please note that we
have consulted with your Manager and worked with technical staffs to develop the proposed RTMP
approach. At this time,we would appreciate comments from your Council and staff on the general direction
as well as specific requirements of the draft RTMP. TRANSPAC intends to use your comments to develop
a RTMP for adoption by TRANSPAC and local jurisdictions which will fulfill the requirements of the
Measure C Growth Management Program.
The draft RTMP combines the environmental assessment requirements of the California Environmental
Quality Act (CEQA) with the development and execution of an intetjurisdictional agreement which details
the mitigation of traffic impacts should a proposed development meet or exceed an established interregional
trip threshold on Routes of Regional Significance.
The intedurisdictional agreement is based on the "Oakhurst model" in which the City of Clayton executed
agreements with the Cities of Concord and Walnut Creek to pay for improvements to Ygnacio Valley Road
which was impacted by the proposed development.
TRANSPAC would appreciate receiving your written comments on the RTMP at your earliest convenience.
Please do not hesitate to contact me or Barbara Neustadter,TRANSPAC Manager at(510) 268-8980,if you
have questions or require additional information.
Sincerely,

, .DRAFT
REGIONAL TRANSPORTATION MITIGATION PROGRAM (RTMP) v
This program mates a requirement for an interjurisdictional agreement(s) to mitigate traffic impacts
should a proposed development meet or exceed the established interregional trip threshold for Routes
of Regional Significance.
1. The Regional Transportation Mitigation Program (RTW) requires the execution of an
interjurisdictional agreement(s) to mitigate the impacts of development generating interregional
trips at or above the threshold on Routes of Regional Significance (Note: a jurisdiction may
voluntarily choose to address impacts of interregional trips on roads other than Routes of
Regional Significance.).
2. For the purposes of the RTW, 'interregional trip' is defined as any trip outside of the 'home'
jurisdiction in which the development is located. The RTW is geared to an assessment of the
impacts of interregional trips on Routes of Regional Significance. Nexus and rough
proportionality requirements are to be individually addressed as part of the proposed
development's environmental assessment under the California Environmental Quality Act,
(CEQA) as amended.
3. The requirements of the RTMP are to be followed if a development project generates SO
interregional trips in any one hour on a Route of Regional Significance as defined in the Central
County Action Plan and/or the Comprehensive Countywide Transportation Plan. Jurisdictions
are to execute a developer sponsored mitigation agreement(s) with any TRANSPAC or other
jurisdiction determined to be impacted by a proposed development. For the purpose of
determining if the 50 trip threshold is met, a cumulative trip analysis must be completed as part
of the CEQA assessment. This cumulative analysis is to review trips not only generated by the
proposed development, but also trips from "related past, present, and reasonably foreseeable
probable future projects.' If such cumulative analysis meets the trip threshold and results in
impacts, the proposed development is responsible for mitigating its proportionate share of the
impacts via an inter urisdictional agreement(s).
4. The required CEQA environmental assessment for a development project is be used to determine
if impacts on Routes of Regional Significance need to be mitigated.
A. If a development project meets or exceeds the threshold established above and the
environmental assessment can be accomplished by a Negative or Mitigated Negative Declaration,
the jurisdiction will undertake a focused traffic study to determine if the requirements of the
RTW apply. The traffic study will assess traffic impacts on Routes of Regional Significance
beyond the home jurisdiction.
Should the requirements apply, the intesjurisdictional agreement(s) on mitigation measures,
actions and/or fees would require the voluntary consent and sponsorship of the project applicant.
(Note: if such voluntary consent is not achieved, CEQA requires that an EIR be prepared, see
Section 4B.) The agreement(s) will be developed in cooperation with affected jurisdictions and
are to include the identification, implementation and monitoring mechanism(s) for mitigation of
impacts (e.g. Central County Action Plan and Countywide Comprehensive Transportation Plan
mitigation measures, actions, paymnt of fees, etc.)
D. If a development project meets or exceeds the threshold and the environmental assessment
requires the preparation of an Environmental Impact Report (EIR), the Elk will include an
analysis of traffic impacts outside the home jurisdiction to determine if the requirements of the
RIW apply. Should the requirements apply, an interjurisdictional agreement(s) establishing
the developer responsibility to mitigate impacts (e.g. Central County Action Plan and
Countywide Comprehensive Transportation Plan mitigation measures, actions, payment of fees,
etc.) is required. The agreement(s) will be developed in cooperation with the affected
jurisdictions and include the identification, implementation and monitoring mechanisms) for
mitigation requirements.
C. If a development project does not exceed the threshold (even under the cumulative analysis)
and the required CEQA assessment is accomplished through a Categorical Exemption, Negative
or Mitigated Negative Declaration, the jurisdiction is not. required to develop an
interjurisdictional agreement(s). Such development projects are li Wy to be small infill projects
which are to be encouraged to promote jobs/housing balance,if residential, or increased services
and sustainability, if non-residential.
TRANSPAC may amend this program with the approval of its member jurisdictions.
