Dear Ms. Kurz:
Thank you for including the California Department of Transportation (Caltrans) in the
environmental review process for the Sunbow II, Phase 3 Draft Environmental Impact
Report (DEIR). The proposed project is located near Olympic Parkway and Interstate
805 (I-805). The mission of Caltrans is to provide a safe, sustainable, integrated, and
efficient transportation system to enhance California’s economy and livability. The
Local Development-Intergovernmental Review (LD-IGR) Program reviews land use
projects and plans to ensure consistency with our mission and state planning priorities.
Caltrans has the following comments:
Traffic
A significant VMT impact was identified in the project’s March 2021-
Transportation Impact Analysis (TIS). The TIS proposes the use of an Adaptive
Traffic Signal Control (ATSC) as one of the project’s mitigations. Caltrans
recommends that the ATSC be implemented as a mitigation instead of only
contributing towards a fair share.
Verification with Caltrans Signal Operations branch will be required to ensure the
proposed Adaptive Traffic Signal Control (ATSC) mitigation method will function
as proposed at intersection number 1- Orange Avenue/I-805 Southbound
Ramps and intersection number 2 - Olympic Parkway/I-805 Northbound Ramps.

The project will produce substantial impacts at intersection 1 and 2. If the signals
are already optimized, and if the ATSC will not be implemented or will not
function as a proposed mitigation, Caltrans recommends other improvements.
Please consider the following:
- Extend the left turn lanes for the southbound I-805 off-ramp to E. Orange
Avenue at intersection number 1.
- Extend the right turn lanes at the northbound I-805 off-ramp to Olympic
Parkway at intersection number 2.
- Both improvements would add storage for the additional trips being
generated from the project.
As part of the TIS, please provide an existing storage and queue length table for
all scenarios at intersections 1 and 2. (existing, existing + project, existing +
project + cumulative, near-term 2024 and long-term 2035). See table below as
an example.
Signal Operations
The signal timing sheets marked ‘Do Not Duplicate’ are not to be duplicated or
included in the report. They need to be removed from the TIS, and any copies
needed should be requested from Caltrans.
The Traffic Impact Analysis needs to show the impact to the I-805 off ramps with
the proposed adaptive system. Adaptive systems do not add capacity, so the
report must include the additional capacity needed and how this storage will
be obtained. Also, please add a discussion of whether the segment is saturated
and how these conditions will be mitigated.

Complete Streets and Mobility Network
The City of Chula Vista Active Transportation Plan, approved in May 2020,
identifies class II bicycle lanes for Orange Avenue and Olympic Parkway.
The existing conditions for active transportation infrastructure at Orange
Avenue/Olympic Parkway and I-805 interchange includes transverse crosswalk
markings and narrow shoulders that are not clearly marked as bicycle lanes.
There are improvements that will enhance the pedestrian and bicycle
infrastructure at this location and that will also complement the traffic signal
improvements.
These active transportation improvements at the Orange Avenue/Olympic
Parkway and I-805 interchange include (but are not limited to):
- Pedestrian and bicycle signage
- Enhanced visibility crosswalks
- Lane width reductions and other roadway striping reconfigurations to
create wider class II bicycle lanes and improved bicycle facility
approaches to the interchange
- Bicycle detection at traffic signals
- Green pavement markings for bicycle lanes
Right-of-Way
Any work performed within Caltrans’ Right-of-Way (R/W) will require
discretionary review and approval by Caltrans and an encroachment permit will
be required for any work within the Caltrans’ R/W prior to construction.
If you have any questions, please contact Roger Sanchez at (619) 987-1043 or by email
at roger.sanchez-rangel@dot.ca.gov.
Sincerely,

Responses to Caltrans Letter on Sunbow II, Phase 3 Environmental Impact Report, dated June 16, 2021
Traffic and Signal Operations
This comment states that the project’s Transportation Impact Analysis (TIA) identifies a significant vehicle
miles travelled (VMT) impact. The comment further states that use of adaptive traffic signal control (ATSC)
is proposed as mitigation. As discussed in the TIA, the project would exceed the VMT threshold by 1.4%
(refer to Table 5-1 of the TIA). However, through implementation of CAPCOA measure LUT-1: Increase
Density, the project VMT calculated via the proxy site would be reduced by 8%, thereby reducing project
VMT below the significance threshold. The TIA does not propose ATSC as mitigation for VMT impacts.
The CEQA Guidelines and relevant case law provide that: “a lead agency for a project has the authority to
require feasible changes in any or all activities involved in the project in order to substantially lessen or
avoid significant effects on the environment, consistent with applicable constitutional requirement such
as the ‘nexus’ and ‘rough proportionality’ standards established by case law.” CEQA Guidelines 15041. See
also Nollan v. California Coastal Comm’n 483 U.S. 825 (1987) and Dolan v. City of Tigard, 512 U.S. 374
(19194). Cities cannot include the cost attributable to existing deficiencies in public facilities but may
include the cost attributable to the increased demand for public facilities reasonably related to the
development project. (Gov’t Code Section 66001(g).) The City cannot require the entire ATSC to be
installed by the applicant or the other improvements listed in the letter because the project's effects are
resolved by the applicant's payment of the TDIF fees. There is no nexus for the conditions requested by
Caltrans and therefore cannot be legally imposed by the City.
CEQA Guidelines section 15064.3, which implements SB 743, establishes VMT as the most appropriate
measure of transportation impacts, resulting in a shift away from the level of service (LOS) analysis that
evaluated a project's impacts on traffic conditions and traffic delay on nearby roadways and intersections.
SB 743 stated that upon certification of the CEQA Guidelines by the California Natural Resources Agency,
"automobile delay, as described solely by LOS or similar measures of vehicular capacity or traffic
congestion, shall not be considered a significant impact on the environment" pursuant to CEQA. See CEQA
Guidelines Section 15064.3 that specifically establishes that a project's effect on automobile delay shall
not constitute a significant environmental impact. Under CEQA a significant impact must exist for
mitigation to be required. Intersection delay does not constitute a significant impact, therefore the ATSC
(and the other Caltrans suggested conditions) cannot be mitigation measures.
As part of the TIA, a project -specific Local Mobility Analysis (LMA) was prepared that focuses on
automobile delay/LOS. The LOS analysis was conducted to id entify roadway deficiencies in the project
study area and recommend project improvements to address such deficiency. The LMA was prepared
for existing plus project conditions, near -term without project conditions, near -term with project
conditions, and year 2035 conditions. The City’s goal for acceptable levels of service is generally LOS D
or better at signalized and unsignalized intersections and LOS C along roadway segments. The LMA is a
City requirement for transportation analysis that is not tied to CE QA; therefore, implementation of
measures to address LOS -related effects does not constitute CEQA mitigation.
The LMA determined that the project would result in effects associated with unacceptable LOS under the
General Plan LOS standards. While Olympic Parkway is built-out and the provision of additional lanes is
considered physically infeasible, it is recommended that payment of the City’s Transportation Development
Impact Fee (TDIF) should be applied towards other planned network enhancements included in the Eastern
TDIF program that would reduce traffic on Olympic Parkway. The majority of the ADTs on Olympic Parkway
are lower under Year 2035 model conditions (which assumes buildout of the City’s General Plan Circulation
Element and includes Project traffic) as compared to the Existing ADTs, counted in January 2020. Table 17-1 of
the TIA shows that, on average, the Year 2035 traffic volumes are 6.1% lower as compared to the Existing ADTs,
which supports the assertation that the contribution of TDIF funds towards other planned network
enhancements included in the Eastern TDIF study will reduce the amount of traffic on Olympic Parkway,
thereby addressing the Project’s substantial cumulative effect identified in the LMA.
In addition, it is recommended that the project provide a fair share contribution toward the provision of ATSC
modules to each signalized intersection along the Olympic Parkway corridor between the I-805 Ramps and La
Media Road (refer to Appendix K for further details). These TDIF and other requirements associated with LOS
deficiencies would be included as part of the project’s conditions of approval, outside of this EIR. However, as
noted above, there is no nexus for installing the entire ATSC system or the other conditions requested by
Caltrans and therefore cannot be legally imposed by the City.
In light of the above discussion, neither the additional queueing analysis nor the requested physical ramp
improvements are within the scope of CEQA. As there is no significant CEQA impact resulting from this
project, the TIA does not need to include a queueing analysis of the I-805 off ramps. In summary, the
information and issues raised by this letter revolve around delay/LOS, which is no longer a valid measure
of impacts that are to be analyzed in a traffic study. See CEQA Guidelines Section 15064.3.
