EXHIBIT A
ADDENDUM TO FINAL ENVIRONMENTAL IMPACT REPORT –
Del Rio Road Commercial Area Specific Plan
(Certified by the Atascadero City Council on June 26, 2012
and amended by the Council on September 22, 2020)
1.1 INTRODUCTION
The California Environmental Quality Act (CEQA) requires public agencies to analyze and
consider the environmental consequences of decisions to approve development projects
that they exercise discretion over. CEQA achieves this objective by requiring agencies to
prepare Environmental Impact Reports (EIR’s) for projects with the potential to cause
significant impacts on the physical environment. EIR’s are public documents that analyze
environmental effects related to the planning, construction, and operation of a project,
and indicate ways to reduce or avoid possible environmental damage. An EIR also
discloses growth-inducing impacts, effects found not to be significant, significant
cumulative impacts, and significant impacts that cannot be avoided, if any. The purpose
of an EIR is to inform. EIR’s are not policy documents that recommend project approval
or denial.
As a lead agency, the City of Atascadero prepared an Environmental Impact Report (EIR)
for the Del Rio Road Commercial Area Specific Plan in compliance with the California
Environmental Quality Act (CEQA) (Public Resources Code, section 21000 et seq.) and
the State CEQA Guidelines (California Code of Regulations, Section 15000 et seq., as
amended). The City Council certified the Final Environmental Impact Report (Final EIR)
for the Del Rio Road Commercial Area Specific Plan at a public hearing on June 26, 2012.
As noted in the Final EIR, the analysis in the Final EIR was at a “project” level of detail,
which anticipated the potential impacts of future approvals to implement the project.
Public Resources Code Section 21166 limits the ability of an agency to require an
additional EIR, once one has been certified for a project. Section 21166 provides as
follows:
§21166. Subsequent or Supplemental Impact Report; Conditions.
When an environmental impact report has been prepared for a project pursuant to this division, no
subsequent or supplemental environmental impact report shall be required by the lead agency or by any
responsible agency, unless one or more of the following events occurs:
(a). Substantial changes are proposed in the project which will require major revisions of the
environmental impact report.
(b). Substantial changes occur with respect to the circumstances under which the project is being
undertaken which will require major revisions in the environmental impact report.
(c). New information, which was not known and could not have been known at the time the
environmental impact report was certified as complete, becomes available.
The CEQA Guidelines further refine the circumstances under which a supplemental or
subsequent EIR may be required. Guidelines Section 15162 provides as follows:
15162. Subsequent EIRs and Negative Declarations.
(a) When an EIR has been certified or negative declaration adopted for a project, no subsequent EIR
shall be prepared for that project unless the lead agency determines, on the basis of substantial evidence in
the light of the whole record, one or more of the following:
(1). Substantial changes are proposed in the project which will require major revisions of the
previous EIR or negative declaration due to the involvement of new significant environmental
effects or a substantial increase in the severity of previously identified significant effects;
(2). Substantial changes occur with respect to the circumstances under which the project is
undertaken which will require major revisions of the previous EIR or negative declaration due to
the involvement of new significant environmental effects or a substantial increase in the severity
of previously identified significant effects; or
(3). New information of substantial importance, which was not known and could not have been
known with the exercise of reasonable diligence at the time the previous EIR was certified as
complete or the negative declaration was adopted, shows any of the following:
(A). The project will have one or more significant effects not discussed in the previous
EIR or negative declaration;
(B). Significant effects previously examined will be substantially more severe than shown
in the previous EIR;
(C). Mitigation measures or alternatives previously found not to be feasible would in fact
be feasible and would substantially reduce one or more significant effects of the project,
but the project proponents decline to adopt the mitigation measure or alternative; or
(D). Mitigation measures or alternatives which are considerably different from those
analyzed in the previous EIR would substantially reduce one or more significant effects on
the environment, but the project proponents decline to adopt the mitigation measure or
alternative.
In 2017, the City amended the Del Rio Specific Plan to accommodate the Hilton Hotel on
the western portion of the “Annex” site of the Del Rio Specific Plan to allow for a hotel
instead of retail development. That amendment recognized a reduction in vehicle trips
and associated environmental impacts. A four-story, 120-room hotel, north of Del Rio
Road, between Hwy 101 and El Camino Real has been recently completed as a result of
that amendment.
In 2017, Walmart notified the City that they would no longer be pursuing the development
of their Del Rio store in Atascadero. In 2019, development plans were officially withdrawn
and the site is being marketed for sale. On July 12th, 2020, the tentative parcel map and
associated Master Plan of Development for the project expired. In 2020 amendments to
the Specific Plan were adopted modifying the list of allowed uses on the site, including
the removal of high traffic generating uses, and mitigation measures were modified to
recognize the reduction in trips and traffic impacts through an addendum to the EIR.
The City is currently processing a Master Plan of Development for the North-East project
site within the Del Rio Specific Plan. The master plan proposes a mix of uses allowed
within the existing Commercial Retail (CR) zoning designation and as modified by the
Specific Plan overlay zone. As traffic impacts and peak hour timing vary from the previous
EIR addendum, a new addendum is being prepared to ensure that mitigation measures
are appropriately correlated to the impacts and to show that impacts remain the same or
are reduced as required by CEQA. The analysis has also shifted from Level of Service
(LOS) to Vehicle Miles Traveled (VMT) with the enaction of new State law. This
addendum considers newly enacted State requirements and reviews traffic impacts
based on VMT, as currently required under CEQA.
Before acting on the proposed amendments, the Planning Commission and the City
Council must apply the standards outlined above to determine whether a subsequent or
supplement EIR is required.
After reviewing the facts and analyzing the circumstances, City staff has determined that
a new EIR is not required because none of the circumstances described in CEQA Section
21166, as implemented by CEQA Guidelines Section 15162, would occur. Staff has
prepared an addendum to discuss these issues and the basis for this determination.
2.0 Del Rio Road / US 101 Interchange / Del Rio Road & El Camino Real
The certified Final EIR for the Del Rio Road Commercial Area Specific Plan included a
traffic analysis originally completed in 2010 for the Specific Plan. In 2019 and 2020,
following Walmart’s cancelation of the Atascadero store and submittal of the Annex site
Master Plan of Development amendment, staff consulted with W-trans to complete a
traffic sensitivity analysis of the Del Rio Road Interchange corridor to assess the intensity
of development that can be accommodated in the vicinity of the Del Rio Road interchange
while maintaining acceptable operations and identify final buildout configurations. New
future growth assumptions were factored in as well as updated regional modeling to ensure
the most accurate impact analysis.
The July 2020 Analysis considered the following:
1. In addition to a higher-altitude evaluation of the traffic generated by predictive land
use development scenarios completed in 2019, the 2020 analysis incorporated
regional growth and 20-year forecast scenarios in order to allow Caltrans to
determine long-range impacts to their facilities and ensure informed future
planning efforts.
2. The analyses investigated the traffic signal configurations, roadway geometrics, and
right-of-way impacts including delay time and queue length. The 2020 analysis
concluded that the mitigation measures proposed (detailed below) are feasible and
appropriate to the impacts.
3. Caltrans owns and operates the two traffic signals at the ramp intersections of Del
Rio and US 101. Caltrans priority will be mainline traffic operations on US 101 and
ensuring exiting traffic does not queue onto the mainline traffic lanes from off ramps.
The analyses studied the timing of the traffic signals and ramp queuing in
preparation for coordinating with Caltrans on implementing the proposed mitigation
measures.
The most recent analysis and addendum modified mitigation measures in response to
changing land use patterns and more current development proposals. Table 1 below
shows the current mitigation measures and recommended timing changes based on the
Marketplace Development plan:
Vehicle Miles Traveled Analysis
While the City of Atascadero has not yet adopted VMT standards the State Office of
Planning and Research (OPR) has published recommended thresholds which are applied
below. OPR’s Technical Advisory on Evaluating Transportation Impacts in CEQA
provides guidance for evaluating VMT for various project types.
Mixed-use projects can evaluate the individual components separately or focus the
analysis on the dominant use. As shown in Table 4, the non-residential components of
the project generate over 90 percent of the project’s daily trips and are therefore the
dominant use. OPR also notes that local- serving retail can be presumed to have a less-
than-significant impact because these uses don’t typically generate new demand, but
instead shift travel patterns as customers shift to more convenient shopping locations.
The proposed retail uses on the site are anchored by a 32,400 sq.ft. grocery store which
is expected to be local serving.
OPR’s suggested threshold for office uses is 15 percent below the regional average of
work VMT. Work VMT captures trips from home to work. The SLOCOG Travel Demand
Model was applied to estimate the work VMT.
The project’s VMT was estimated using the SLOCOG Travel Demand Model. The
regional VMT is summarized in Table 2.
The project is expected to increase overall regional VMT slightly and reduce residential
and office VMT. This reduction in office VMT and residential VMT indicates a less-than-
significant impact to VMT. The retail component of the project is considered local-serving
and is presumed to have a less than-significant VMT impact.
The provision of commercial uses in a predominantly residential area improves the jobs-
housing balance which shortens commute trips lengths. The mix of uses on the project
site provides destinations serving project residents as well as other residents nearby. This
is consistent with SB 743 and regional planning goals to encourage mixed-use infill
developments.
Summary
The certified Final EIR, with the inclusion of mitigation measures in the certified Final EIR,
modified with input from Caltrans, concluded that, in order to mitigate impacts created by
the completion of the Del Rio Road Commercial Area Specific Plan, a new 5-legged
roundabout would be needed at the US 101 / Del Rio Road interchange. With the revised
land-use development scenarios including updated future regional impacts and future
anticipated development within the City, the new 2020 traffic analysis concluded that
construction of roundabouts is not warranted and that alternative mitigation strategies can
be implemented that will maintain functionality of the overpass and intersections.
With the revised land-use development scenarios for the Specific Plan area and updated
projections for local and regional growth, traffic impacts at the Del Rio / 101 interchange
and at the Del Rio / El Camino Real intersection decrease. The supplemental traffic
analysis completed for the Del Rio Marketplace in 2022 show that there are no "new
significant environmental effects or substantial increase in the severity of previously
identified significant effects." (Section 15162(a)(1)). Conditions have been included for
the project that modify the timing of mitigations measures and mitigation measures have
been updated to include this revised timing.
2.1 Application of CEQA Guideline Section 15612
Is there substantial evidence in the record revealing that there have been substantial
changes proposed in the project which will require major revisions of the previous
EIR due to the involvement of new significant environmental effects or a substantial
increase in the severity of previously identified significant effects as a result of the
Master Plan of Development amendment and revised land use development
scenarios?
No. The City has completed extensive analyses of the revised traffic impacts based on
the modified land use development scenarios and the estimated foreseeable regional and
local future impacts. Under the anticipated land use scenarios throughout the Specific
Plan area and the submitted Master Plan of Development for the Del Rio Marketplace,
the modified development pattern will result in a decrease in traffic impacts until full build-
out of the area, supporting modified mitigation timing, both at the interchange and local
intersection. As noted above, the original EIR analyzed the impacts of the Specific Plan
Amendment with regionally serving commercial retail uses throughout the majority of the
project. The 2020 addendum analyzed land uses comprised of a mixture of residential,
retail, office park, and tourist serving uses. With the supplemental traffic analysis
identifying uses in both the Specific Plan area, as well as an update to the baseline and
regional traffic modeling, impact timing is modified and mitigation is proposed that
responds to these changes. The amendment to the mitigation measures responds to the
Master Plan of Development for the Del Rio Marketplace, ensuring that development
within the Specific Plan area does not degrade the interchange to unacceptable levels.
The proposed modification allows for property development to proceed with construction
of identified improvements and fair-share fees associated with impacts that necessitate
improvements at full area build-out. Therefore, no new significant environmental effects
or a substantial increase in the severity of previously identified significant effects has
been identified with this analysis that would result in major changes to the FEIR. The
proposed amendments, as has been shown, maintain the environmental impact
resulting from development within the Specific Plan area and modify mitigation timing
to respond to proposed development plans.
Is there substantial evidence in the record revealing that there have been substantial
changes with respect to the circumstances under which the project is undertaken
which will require major revisions of the previous EIR due to the involvement of new
significant environmental effects or a substantial increase in the severity of previously
identified significant effects as a result of the MP Annex LLC’s proposed hotel use
within the Specific Plan?
No, there is no evidence suggesting that there have been substantial changes with
respect to the circumstances under which the project is undertaken which will require
major revisions to the previous EIR due to the involvement of new significant impacts or
increases in the severity of previously identified impacts. All uses proposed are allowed
or conditionally allowed within the underlying Commercial Retail (CR) zoning designation.
The additional traffic supplemental analysis reveals that no new significant environmental
effects would result from the development plan and there will be no increase in the
severity of any previously identified significant effects. It has been shown that the
proposed amendments will in fact decrease the immediacy of traffic impacts to the Del
Rio / 101 interchange as well as the Del Rio / El Camino Real intersection.
Is there substantial evidence in the record revealing that there is new information of
substantial importance related to the proposed amendments, which was not known
and could not have been known with the exercise of reasonable diligence at the time
the previous EIR was certified that shows: (1) the project will have one or more
significant effects not discussed in the EIR, (2) significant effects previously shown
will be substantially more severe that shown in the previous EIR, (3) mitigation
measure or alternatives previously found to be infeasible would in fact be feasible, or
(4) there are considerably different mitigation measure or alternatives from those
analyzed in the previous EIR that would substantially reduce one or more significant
effects?
No, there is no evidence suggesting that there is new information of substantial
importance relating to new significant effects or the severity of previously identified
significant effects, or new alternatives or mitigation measures or the efficacy of previously
considered alternatives or mitigation measures. At the time of the certification of the
original EIR, traffic impacts and mitigations were identified based on the construction of
a regional retail center on the Annex portion of the Specific Plan area and a Walmart store
on the Major Tenant site. The 202 EIR Addendum analyzed a modified land use pattern
and determined that impacts would be substantially less with full project area build-out,
eliminating the need for round-abouts at the affected intersections. This new analysis
reveals that no new significant environmental effects would result from the development
of the Marketplace project as proposed, and in fact there will be a modification in traffic
patterns and peak-hour impacts that allow for modified mitigation measure timing and
signal function. As a consequence of this conclusion, it can be concluded that no new
mitigation measures or alternatives need be analyzed.
3.0 BASIS FOR DECISION TO PREPARE AN ADDENDUM
CEQA Guidelines Section 15164 explains when an addendum to an EIR is required:
(a) The lead agency or a responsible agency shall prepare an addendum to a
previously certified EIR if some changes or additions are necessary but none
of the conditions described in Section 15162 calling for preparation of a
subsequent EIR have occurred.
(b) An addendum to an adopted negative declaration may be prepared if only
minor technical changes or additions are necessary or none of the conditions
described in Section 15162 calling for the preparation of a subsequent EIR
or negative declaration have occurred.
(c) An addendum need not be circulated for public review but can be included
in or attached to the final EIR or adopted negative declaration.
(d) The decision-making body shall consider the addendum with the final
EIR or adopted negative declaration prior to making a decision on the
project.
(e) A brief explanation of the decision not to prepare a subsequent EIR pursuant
to Section 15162 should be included in an addendum to an EIR, the lead
agency's required findings on the project, or elsewhere in the record. The
explanation must be supported by substantial evidence.
Although the project description has been refined with the submittal of a more
precise development plan, an addendum is appropriate because impacts have been
shown to decrease or say the same from the previously certified FEIR as amended
and because none of the conditions described in Section 15162 calling for
preparation of a subsequent EIR have occurred.
More specifically, the project will reduce or maintain the level of anticipated traffic
intensive development, therefore maintaining acceptable levels of service and
supporting reduced VMT. These occurrences do not constitute substantial changes
to the project or the circumstances due to the involvement of new significant
environmental effects or a substantial increase in the severity of previously identified
significant effects. Similarly, neither subsequent considerations nor statutory
changes constitute new information that would show new effects or substantially
more severe effects. Likewise, there are no known mitigation measures that would
in fact be infeasible or that the project proponents have declined to implement.
Furthermore, there have been no other changes, evidence or new information which
would require revisions to the previous EIR. Because none of the criterion in section
15162 has been met, an addendum is appropriate.

Draft Transportation Impact Study Introduction
Executive Summary
This study evaluates the potential transportation impacts of the proposed Del Rio Marketplace project
in the City of Atascadero. The project includes a grocery store under Phase 1 and additional retail, light
industrial, office, and residential uses under Phase 2. The following sections summarize the key
findings:
Intersection Operations: The study intersections operate acceptably under Existing Plus Approved
Plus Project Conditions except at the Del Rio Road/El Camino Real (#4) intersection where the
following improvements are recommended prior to occupancy of the first phase:
• Add a westbound left turn lane with permissive phasing,
• Modify the southbound and northbound left turns to protected-permissive phasing,
• Restripe the eastbound approach to a left, through, and right turn lane and modify the left
turn to protected-permissive phasing,
• Add overlap phasing to the southbound right turn pocket currently under construction,
• Replace eight-inch traffic signal heads with 12-inch heads,
• Install yellow reflective tape on all backplates,
• Install new signage and replace non-reflective signs, and
• Optimize signal timings including updating pedestrian and yellow clearance times.
In addition, the following improvements are recommended under Cumulative Conditions:
• Del Rio Road/Ramona Road (#1): Realign Ramona Road approximately 200 feet west of the
existing location to provide greater separation from the US 101 Southbound Ramps.
• Del Rio Road/US 101 Southbound Ramps (#2): Construct an eastbound right turn lane and
optimize the coordinated signal timing with the Northbound Ramps.
• Del Rio Road/US 101 Northbound Ramps (#3): Construct a westbound right turn lane and
optimize the coordinated signal timing with the Southbound Ramps.
The improvements recommended prior to Phase 1 at the Del Rio Road/El Camino Real (#4)
intersection operate at level of service (LOS C) under Cumulative Conditions with the addition of
project traffic. No traffic signal coordination or restriping of the northbound approach are required
for acceptable queuing.
We recommend the project construct the improvements at Del Rio Road/El Camino Real (#4) and
make a fair share contribution towards the recommended improvements west of El Camino Real.
Site Access and On-Site Circulation: As shown on Figure 2, the project proposes two driveways
on El Camino Real and two on Del Rio Road with limited access proposed and recommended at two
of the driveways. We recommend truck turning templates for deliveries and fire access be applied to
the ultimate site plan and frontage improvement designs. We also recommended convenient sidewalk
connections between all buildings and the frontage improvements, and crosswalks and bike parking be
provided at key locations.
Vehicle Miles Traveled (VMT): The project is expected to have a less-than-significant impact to
VMT.

Draft Transportation Impact Study Introduction
1.0 Introduction
This study evaluates the potential transportation impacts of the proposed Del Rio Marketplace project
in the City of Atascadero. The project includes a 32,400 square foot (s.f.) grocery store under Phase 1
and 203,700 total s.f. including additional retail, light industrial, office, and residential units under Phase
2. The project location and study intersections are shown on Figure 1. The site plan is shown in Figure
2.
The following intersections were analyzed during the weekday PM peak hour:
1. Del Rio Road/Ramona Road
2. Del Rio Road/US 101 Southbound Ramps
3. Del Rio Road/US 101 Northbound Ramps
4. Del Rio Road/El Camino Real
5. Del Rio Road/Del Rio Marketplace/Del Rio Ranch
6. El Camino Real/Del Rio Marketplace Southern Driveway
The level of service (LOS) and queuing are reported for each of the study intersections. The
intersections were evaluated under the following scenarios:
• Existing Conditions reflects recent traffic counts and the existing transportation network.
• Existing Plus Approved Plus Phase 1 adds approved and constructed projects plus Project-
generated grocery store traffic to Existing Conditions volumes.
• Existing Plus Approved Plus Project (Phase 1 and 2) adds approved and constructed
projects plus Project-generated traffic to Existing Conditions volumes.
• Cumulative Plus Project represents future traffic conditions reflective of the buildout of
land uses in the area, including the proposed Project.
Each scenario is described in more detail in the appropriate chapter.
1.1 BACKGROUND
The project would develop the northeast corner of El Camino Real/Del Rio Road (known as the
‘Annex East’) east of the US 101/Del Rio Road interchange. Past studies identified the need for new
roundabouts along Del Rio Road to accommodate traffic from the Walmart project and other area
development. The withdrawal of the Walmart project enabled identification of smaller and less costly
improvements to maintain traffic flows and acceptable operations.
1.1.1 Del Rio Road Interchange Traffic Analysis
The Del Rio Road/US 101 Interchange Traffic Sensitivity Analysis (W-Trans, March 2020) was prepared to
evaluate multiple land use alternatives and their potential impacts to the Del Rio Road/US 101
interchange. This analysis resulted in the abandonment of the roundabout concept in favor of lower
cost improvements to the signalized intersections along the corridor. Mitigation 1 would add a
westbound right turn lane to the Del Rio Road/US 101 NB Ramps and Mitigation 2 would retime the
signals and modify the Del Rio Road/El Camino Real intersection to construct a southbound right
turn lane and provide more efficient signal phasing. Combined, these two mitigations would result in
acceptable operations under the most intensive likely scenario.

Draft Transportation Impact Study Introduction
1.1.2 Del Rio Commercial Area Specific Plan
The proposed project is in the Del Rio Commercial Area Specific Plan. The Specific Plan was amended
to accommodate the withdrawal of the Walmart project and interest in alternative land uses. The
amendment and Final Environmental Impact Report (FEIR) Addendum were supported by the Del
Rio Specific Plan Amendment Traffic Analysis (W-Trans, August 2020) that describes existing and future
traffic operations along Del Rio Road.
The traffic analysis identifies four mitigations, effectively the same as Mitigation 1 and 2 described
above in the Del Rio Road Interchange Traffic Analysis section, which can accommodate the planned
growth with acceptable traffic operations. It also concludes that a large regional retail project on the
Walmart site would require widening the Del Rio Road overcrossing. The amendment assumed this
site would be a Business Park.
Since the amendment, additional information about project development east and west of the Del Rio
Interchange has been received from applicants. In May 2021, CCTC prepared the Del Rio Ranch
Transportation Impact Study for the former Walmart site south of Del Rio Road. The proposed project’s
land uses included light industrial, multi-family dwellings, RV campsites, a hotel, a conference center,
an amphitheater, and a small shopping center. In January 2022, CCTC prepared the Barrel Creek Draft
Transportation Impact Study located north of Del Rio Road and west of US Highway 101. The proposed
project’s land uses included light industrial, single family dwellings, multi-family dwellings, a hotel, a
restaurant and a winery and brewery.
The amended Specific Plan recommended that the traffic signal modifications described in mitigation
4 at the Del Rio Rd/El Camino Real (#4) intersection be completed prior to occupancy of the Business
Park. The Specific Plan mitigations and recommendations are summarized in Table 1.
Central Coast Transportation Consulting March 2022

Draft Transportation Impact Study Introduction
Table 1: Amended Specific Plan Mitigation Summary
Consistent with the amended Specific Plan, we recommend the Del Rio Rd/El Camino Real (#4)
intersection improvements be completed prior to occupancy of the proposed project.
Amended Specific Plan Potential Study Area Mitigations CCTC Recommendation
#1: This mitigation measure includes the addition of a westbound right-turn lane to
the intersection of Del Rio Rd/US 101 NB Ramps, such that there would be two
westbound lanes on Del Rio Rd from El Camino Real to US 101 NB Ramps. This
would require widening Del Rio Rd, the construction of a retaining wall on the north
side, and reconstruction of the curb return. By splitting westbound traffic into
through and right-turn lanes, the queue length could be reduced by providing drivers
two lanes to stack in rather than one for both movements combined. Additionally,
splitting through and right-turning traffic would allow turning drivers to bypass
through drivers who are waiting for a green light, reducing delay and improving
operations at Del Rio Rd/US 101 NB Ramps.
Existing Plus Approved Plus
Project volumes operate
acceptably without the
additional westbound right turn

Northbound Ramps (#3).
Recommend project pay their
fair share toward future
improvements.
#2: This mitigation measure would involve several modifications to the traffic signal
at Del Rio Rd/El Camino Real to more efficiently orchestrate the movement of
conflicting traffic. This modification involves the replacement of the northbound left-
turn protected phasing (green arrow) with protected-permissive phasing (green arrow
that goes to green ball or flashing yellow arrow), and the southbound left-turn
protected phasing with permissive phasing (green ball or flashing yellow arrow). The
eastbound and westbound phases, which currently activate at the same time, would
be split to operate sequentially, or one direction and then the other. These changes
would require modification to the existing signal infrastructure to incorporate updated
signal heads. In addition, this mitigation includes adjustment to the signal phasing in
terms of recalls, phase lengths, and the overall cycle length.
Protected -permissive phasing is
recommended on both the
northbound and southbound
approaches, see #4. Eastbound
and westbound split phasing
not recommended as interim
measure based on unacceptable
operations with project traffic.
#3: 'This mitigation measure would combine Mitigation 1 and 2.Not recommended, see #2.

project construct the following
improvements prior to
occupancy:
- Restripe eastbound approach
to a left, through, and right turn
lane.
- Install westbound left turn
lane.
- Modify all approaches to
protected-permissive phasing
except westbound.
- Install southbound right turn
overlap.
- Update signal timing.
#4: This option includes any modifications that may be required to achieve
acceptable operations with the addition of traffic that would be generated by the
Amended Specific Plan scenario. In addition to Mitigation 1 and Mitigation 2 above,
the intersection of Del Rio Rd/El Camino Real would need to be further modified to
reconfigure the eastbound approach from through/left-turn and right-turn lanes, to
left-turn lane and through/right-turn lanes, essentially moving the through movement
from the left lane to the right lane. This may require widening the eastbound
departure (on the east leg of the intersection) to avoid excessive lateral shifting of
through traffic. With a dedicated eastbound left-turn lane, the eastbound-westbound
split phasing could be replaced with concurrent timing, as well as protected-
permissive phasing for the eastbound left-turn movement. With protected left-turn
phasing in the eastbound direction and a prohibition of eastbound U-turns, it would
be possible to include a southbound right-turn overlap, which is a green arrow that
enables southbound right turning drivers to continue without stopping concurrently
with the eastbound left-turn movement. Additionally, the signal at Del Rio Rd/El
Camino Real would need to be coordinated with the signals at Del Rio Rd/US 101
NB Ramps and Del Rio Rd/US 101 SB Ramps. This would require extending the
interconnect hardware between the ramp signals to Del Rio Rd/El Camino Real, and
potentially upgrading the signal hardware at Del Rio Rd/El Camino Real to be
compatible with interconnect technology if it is not already. (Note: Existing
interconnect conduit and cable.)

Draft Transportation Impact Study CEQA Transportation Analysis
2.0 CEQA Transportation Analysis
This section presents analysis relevant to the California Environmental Quality Act (CEQA), notably
analysis of the existing setting, plan consistency, vehicle miles traveled (VMT), and transportation
safety.
2.1 EXISTING CIRCULATION NETWORK
The existing roadways adjacent to the proposed project are described below.
• US 101 is a four-lane freeway serving intercity and regional travel. There is a full access
interchange at Del Rio Road.
• El Camino Real is a major arterial paralleling US 101. There are two to four travel lanes, Class
II bikeways, and intermittent sidewalks.
• Del Rio Road is a minor arterial west of El Camino Real and a collector east of El Camino Real.
There are two travel lanes, intermittent Class II bike lanes, and intermittent sidewalks. There
are proposed Class II bike lanes through the study area.
The existing study intersections are described below:
• Del Rio Road/Ramona Road (#1) Side-street stop controlled with marked crosswalk on the
south leg only.
• Del Rio Road/US 101 Southbound Ramps (#2): Existing traffic signal with marked crosswalk
and pedestrian signals on the south leg only.
• Del Rio Road/US 101 Northbound Ramps (#3): Existing traffic signal with marked crosswalk
and pedestrian signals on the south leg only.
• Del Rio Road/El Camino Real (#4): Existing traffic signal with marked crosswalks and
pedestrian signals on all legs.
2.1.1 Transit
The San Luis Obispo Regional Transit Authority (RTA) operates fixed route transit service in the study
area. RTA Route 9 is a bus service traveling between San Luis Obispo, Santa Margarita, Atascadero,
Templeton, Paso Robles, and San Miguel with hourly headways on weekdays and reduced frequency
on weekends. The closest bus stops to the project site are on El Camino Real south of Del Rio Road
at Mission Oaks Plaza.
2.2 CEQA TRANSPORTATION THRESHOLDS
The CEQA transportation thresholds are described below.
2.2.1 City of Atascadero
While the City of Atascadero has not yet adopted VMT standards the State Office of Planning and
Research (OPR) has published recommended thresholds which are applied below. OPR’s Technical
Advisory on Evaluating Transportation Impacts in CEQA provides guidance for evaluating VMT for various
project types.
Mixed-use projects can evaluate the individual components separately or focus the analysis on the
dominant use. As shown in Table 4, the non-residential components of the project generate over 90
percent of the project’s daily trips and are therefore the dominant use. OPR also notes that local-

10Del Rio Marketplace
Draft Transportation Impact Study CEQA Transportation Analysis
serving retail can be presumed to have a less-than-significant impact because these uses don’t typically
generate new demand, but instead shift travel patterns as customers shift to more convenient shopping
locations. The proposed retail uses on the site are anchored by a 32,400 s.f. grocery store which is
expected to be local serving.
OPR’s suggested threshold for office uses is 15 percent below the regional average of work VMT.
Work VMT captures trips from home to work. The SLOCOG Travel Demand Model was applied to
estimate the work VMT.
While LOS is not an allowable CEQA metric it remains in planning documents for the City of
Atascadero and is analyzed under the local transportation analysis section of this report.
2.2.2 Caltrans
Caltrans has eliminated LOS consistent with SB 743 and now relies on VMT and safety to evaluate
transportation impacts. Caltrans recently issued a series of policy documents related to transportation
impacts and CEQA determinations. Caltrans published a VMT-Focused TIS Guide in May 2020 which
replaced the prior guide reliant on LOS. The TIS Guide notes that lead agencies have the discretion to
choose VMT thresholds and methods, and generally conforms to OPR guidance.
2.3 RTP CONSISTENCY
SLOCOG’s 2019 Regional Transportation Plan (RTP) serves as a blueprint planning the region’s
transportation system. It integrates land use and transportation planning to identify and prioritize
regional transportation improvements.
Figure 13-7 of the RTP shows an existing jobs-housing imbalance within subregions, with the Central
County subregion having more than two jobs per housing unit and all other subregions having less
than one job per housing unit. This imbalance causes congestion and increases trip lengths as
commuters travel to and from the Central County for work.
The RTP’s Action Strategies direct new growth to existing mixed-use corridors since these areas
support a more efficient transportation network. El Camino Real is one of four corridors identified in
the RTP as the priority areas for growth.
The proposed project conforms to the RTP’s preferred growth scenario by adding jobs to a mixed-use
corridor in the North County subregion, thereby improving the jobs-housing balance in the region and
improving land use location efficiency.
2.4 VEHICLE MILES TRAVELED (VMT)
The project’s VMT was estimated using the SLOCOG Travel Demand Model. The regional VMT is
summarized in Table 2.
Central Coast Transportation Consulting March 2022
11Del Rio Marketplace
Draft Transportation Impact Study CEQA Transportation Analysis
Table 2: VMT Analysis
The project is expected to increase overall regional VMT slightly and reduce residential and office
VMT. This reduction in office VMT and residential VMT indicates a less-than-significant impact to
VMT. The retail component of the project is considered local-serving and is presumed to have a less-
than-significant VMT impact.
The provision of commercial uses in a predominantly residential area improves the jobs-housing
balance which shortens commute trips lengths. The mix of uses on the project site provides
destinations serving project residents as well as other residents nearby. This is consistent with SB 743
and regional planning goals to encourage mixed-use infill developments.
2.5 EMERGENCY ACCESS
The project proposes four driveways, two on Del Rio Road and two on El Camino Real. We
recommend truck turning templates for fire access be applied to the ultimate site plan and frontage
improvement designs to confirm adequate emergency access. Fire Department approval is also
required on all development plans.
2.6 COLLISIONS
CCTC obtained traffic collision data from the Statewide Integrated Traffic Records System (SWITRS),
the City’s collision database, and the Caltrans Traffic Accident Surveillance and Analysis System
(TASAS). The US 101 Northbound and Southbound ramp intersections have a total collision rate
lower than the statewide average.
The average collision rate at the Del Rio Road/El Camino Real (#4) intersection exceeds the statewide
average collision rate for similar facilities. Approximately 30 percent of collisions were caused by
improper turning, 20 percent auto right-of-way violations, and an additional 20 percent unsafe speed.
50 percent of collisions involved a fixed object and approximately 20 percent of collisions were
broadside. No pedestrian, bicycle, severe injury, or fatal collisions occurred. We recommend the
following be completed with the improvements at Del Rio Road/El Camino Real (#4):
• Replace eight-inch traffic signal heads with 12-inch heads.
• Install yellow reflective tape on traffic signal backplates.
• Install LEFT TURN YIELD ON GREEN (R10-12) and TURNING VEHICLES YIELD
TO PEDESTRIANS (R10-15) signs as needed.
• Replace signs to comply with CAMUTCD Table 2A-3 for sign reflectivity.

Draft Transportation Impact Study Local Transportation Analysis
3.0 Local Transportation Analysis
While LOS is not an allowable CEQA metric it remains in planning documents for the City of
Atascadero. The study intersections were analyzed with the Synchro 10 software package applying the
HCM 6th Edition methods, except where unusual signal phasing required the use of HCM 2000.
The City’s Circulation Element specifies that level of service (LOS) C or better operations shall be
maintained as the standard at all intersections and on all arterial and collector roads. Upon City Council
approval, LOS D is acceptable where residences are not directly impacted and improvements to meet
the City’s standard would be prohibitively costly or disruptive.
Caltrans has eliminated LOS consistent with SB 743 and now relies on VMT and safety to evaluate
transportation impacts.
3.1 EXISTING OPERATIONS
Traffic count data at the study intersections was collected in February 2022. Consistent with recent
studies in the area, only the weekday PM peak hour was analyzed since this is the hour which dictates
future improvements. Additionally, the project is expected to generate more vehicle trips during the
PM peak hour than during the AM peak hour, as shown in the trip generation section of this report.
Figure 3 shows the existing traffic volumes and lane configurations. Traffic count sheets are provided
in Appendix A. Table 3 summarizes the LOS, with detailed calculation sheets included in Appendix
B.

3.2 EXISTING PLUS APPROVED PLUS PROJECT CONDITIONS
The amount of traffic affecting the study locations is estimated in three steps: trip generation, trip
distribution, and trip assignment. Trip generation refers to the total number of trips generated by the
site. Trip distribution identifies the general origins and destination of these trips, and trip assignment
specifies the routes taken to reach these origins and destinations.
3.2.1 Trip Generation
The Institute of Transportation Engineers (ITE) Trip Generation Manual 11th Edition was used to
estimate the trip generation of the Del Rio Marketplace project. Pass-by and internal capture trips were
deducted to obtain total external trips. Table 4 summarizes the project trip generation.
Table 4: Trip Generation
The proposed project would generate 5,495 net new trips per weekday, including 327 AM peak hour
trips and 397 PM peak hour trips. The project trip generation is similar to the original Specific Plan as

Table 7: Existing Plus Approved Plus Project PM Peak Hour Intersection Queues
All study locations operate with acceptable LOS with the addition of project traffic except Del Rio
Road/El Camino Real (#4). The eastbound left turn movement queue exceeds storage at the
intersection with the addition of project traffic.
At Del Rio Road/US 101 Southbound Ramps (#3), the addition of project traffic would cause the
eastbound through movement queue to block the upstream intersection of Ramona Road.
3.3.1 Recommended Improvements
The following intersection improvements are recommended with the addition of project traffic:
• Del Rio Road/Ramona Road (#1): Ramona Road carries low volumes, the queues reported at
the Southbound Ramps would not be exceeded 95 percent of the time, and average queues
are not expected to block Ramona Road. Do Not Block Intersection Markings per the
California Manual on Uniform Traffic Control Devices (CAMUTCD) Section 3B.17 could be
considered to address this infrequent blockage.
• Del Rio Road/El Camino Real (#4): The following improvements would bring the
intersection operations to LOS B with acceptable queuing and are recommended prior to
occupancy of the first phase:
o Add a westbound left turn lane with permissive phasing,
o Modify the southbound and northbound left turns to protected-permissive phasing,
o Restripe the eastbound approach to a left, through, and right turn lane and modify
the left turn to protected-permissive phasing,

3.4 SITE ACCESS AND ON-SITE CIRCULATION
This section discusses issues related to site access and on-site circulation. On-site circulation
deficiencies would occur if the project designs fail to meet appropriate standards, provide adequate
truck access, or would result in hazardous conditions.
The American Association of State Highway and Transportation Officials (AASHTO) states that,
“ideally, driveways should not be located within the functional area of an intersection or the influence
area of an adjacent driveway.”
As shown on Figure 2, the project proposes two driveways on El Camino Real and two driveways on
Del Rio Road. Full access is proposed at the northern driveway on El Camino Real across from an
existing driveway and on Del Rio Road across from the future Del Rio Ranch entrance. Right-in/right-
out only turns are recommended and proposed at the eastern driveway on Del Rio Road due to the
proximity to the Obispo Road intersection. Left-in/right-in/right-out only turns are recommended
and proposed at the southern driveway on El Camino Real due to the proximity to the Del Rio
Road/El Camino Real (#4) intersection.
To maintain sight distance at project driveways, all landscaping, signage, or other obstructions shall
comply with City Standard Drawing Number 414.
Preliminary truck turning templates provided by the applicant may have used a larger design vehicle
than necessary and showed the need for one way travel on the internal circulation system during
deliveries. Truck turning templates for truck deliveries and fire access should be applied to the ultimate
site plan and frontage improvement designs. We recommend two-way travel with allowance for
oncoming vehicles be provided on roadways fronting buildings.
We recommend convenient sidewalk connections between all buildings, the frontage improvements,
and crosswalks at key locations. Convenient and secure bike parking should also be provided at the
market, plazas, and/or building entrances.
3.5 CUMULATIVE PLUS PROJECT CONDITIONS
Cumulative Conditions (2035) represent build-out of the land uses in the region. Cumulative traffic
volume forecasts were developed based on the Del Rio Commercial Area Specific Plan Amendment Traffic
Analysis (W-Trans, August 2020), Del Rio Ranch Traffic Impact Study (CCTC, May 2021), and the Barrel
Creek Draft Traffic Impact Study (CCTC, January 2022). The amended Specific Plan analysis forecasts
were updated to include the Del Rio Ranch and Barrel Creek projects as currently proposed. In
addition, the forecasts were updated based on the difference between the 2022 counts and the 2018
data previously used in the Specific Plan amendment. The estimated trips from the existing hotel were
also subtracted from the cumulative base volumes.
Figure 6 shows the Cumulative Plus Project traffic volumes, respectively. Under Cumulative
Conditions, a peak hour factor (PHF) of 0.92 was used for the analysis. In addition, two percent trucks
were assumed under Cumulative Conditions.

Table 9: Cumulative and Cumulative Plus Project PM Peak Hour Queues
The following LOS and queuing deficiencies are reported:
• Del Rio Road/US 101 Southbound Ramps (#2): The eastbound through movement queue
length further blocks the Ramona Road intersection and the westbound through movement
exceeds the storage length on the US 101 overpass. The southbound offramp approach queues
would not affect US 101 freeway operations.
• Del Rio Road/US 101 Northbound Ramps (#3): The eastbound through movement queues
exceed the storage length on the US 101 Overpass and the westbound queue would reach El
Camino Real. The northbound offramp approach would not affect US 101 freeway
operations.
• Del Rio Road/El Camino Real (#4): The intersection operates unacceptably, and the
northbound left turn and eastbound left/through queue length exceeds the available storage.
3.5.1 Recommended Cumulative Improvements
The following improvements are recommended at the study intersections under Cumulative Plus
Project Conditions:
• Del Rio Road/Ramona Road (#1): Consistent with recent studies in the area, realigning
Ramona Road approximately 200 feet to the west would provide greater separation from the
US 101 ramps and accommodate the queues.
• Del Rio Road/US 101 Southbound Ramps (#2): Consistent with recent studies in the area,
optimizing signal timings would improve corridor operations. In addition, an eastbound right

turn lane is recommended to reduce queuing on the US 101 overpass. The turn lane could use
the existing Ramona Road intersection approach and be constructed when the Del Rio
Road/Ramona Road (#1) intersection is realigned.
• Del Rio Road/US 101 Northbound Ramps (#3): Consistent with recent studies in the area,
constructing a westbound right turn lane and optimizing signal timings would improve
corridor operations.
• Del Rio Road/El Camino Real (#4): The improvements recommended under Existing Plus
Approved Plus Project Conditions operate at LOS C with acceptable queuing under
Cumulative Plus Project Conditions. The natural cycle length at the US 101 Ramp intersections
is shorter than the El Camino Real intersection due to the number of intersection approaches
and crosswalk lengths. With an additional turn lane added in each direction between the US
101 Northbound Ramps and El Camino Real, traffic signal coordination or restriping of the
northbound approach is not required or recommended.
With the recommended improvements, all study intersections would operate acceptably at LOS C or
better and queuing would not encroach into the deceleration distance needed for vehicles exiting US
101.
All recommended intersection improvements have been previously identified in historic studies except
the eastbound right turn lane at Del Rio Road/ US 101 Southbound Ramps (#3).
We recommend the project make a fair share contribution towards the cost of the improvements at
Ramona Road and the US 101 Ramp intersections. We recommend the project construct the proposed
improvements at Del Rio Road/El Camino Real (#4) prior to occupancy of the first phase.

Concurrent with the addition of the right turn lane noted above, the
intersection of Del Rio Road/El Camino Real shall be reconfigured at
the eastbound approach from through /left-turn and right-turn lanes,
to left-turn lane and through/right-turn lanes, moving the through
movement from the left lane to the right lane.
This includes widening the eastbound departure (on the east leg of the
intersection) to avoid excessive lateral shifting of through traffic. With
a dedicated eastbound left-turn lane, the eastbound-westbound split
phasing shall be required to be replaced with concurrent timing, as well
as protected-permissive phasing for the eastbound left-turn movement.
With protected left-turn phasing in the eastbound direction and a
prohibition of eastbound U-turns, a southbound right-turn overlap shall
be provided, which is a green arrow that enables southbound right-
turning drivers to continue without stopping concurrently with the
eastbound left-turn movement. Additionally, the signal at Del Rio
Road/El Camino Real shall be coordinated with the signals at Del Rio
Road/US 101 North Ramps and Del Rio Road/US 101 South Ramps.
This will require extending the interconnect hardware between the
ramp signals to Del Rio Road/El Camino Real, and potentially
upgrading the signal hardware at Del Rio Road/El Camino Real to be
compatible with interconnect technology if it is not already.
All development within the Specific Plan area shall be responsible for
paying their fair share towards these improvements as a special impact
fee. The special impact fee will be in addition to the Citywide impact
fees in place at the time of development and shall be collected prior to
issuance of any permit. Should a developer construct the improvements,
any costs of the installed improvements in excess of the project’s
proportional share, may be eligible for a TIF fee credit. Any potential
TIF fee credit will be calculated by the City and will comply with any
City resolution guiding TIF Fee credits in place at the time of
construction of the improvements. The developer constructing the
improvements may also be eligible for reimbursement from other
development within the Specific Plan area should improvements be
installed prior to Specific Plan build-out.

Prior to issuance of building permits for any land use that exceeds 293
traffic capacity cumulative weekday p.m. peak hour trips within the
Specific Plan area, the following improvements shall be completed, as
determined by a traffic analysis for each project and subject to the
approval of the City Engineer:
Widening the eastbound approach to Del Rio Road/El Camino
Real to three lanes that extend upstream to Del Rio Road/US
101 North Ramps, with one lane each assigned to left turns,
through lanes, and right turns.
The westbound approach to US 101 north ramps shall be
widened to include a right-turn only pocket.
A second northbound left-turn lane at Del Rio Rd/El Camino
Real shall be constructed to accommodate traffic leaving the
commercial developments and heading toward the freeway.
Overlaps to traffic signal operations shall be added to further
improve traffic flow.
The Del Rio Road overpass shall to be widened to four lanes,
with a through/left-turn combined lane and through lane
approaching eastbound to Del Rio Road/US 101 North Ramps
and left-turn and through/left-turn combined lanes on the
westbound approach to Del Rio Road/US 101 South Ramps.
At Del Rio Road/US 101 South Ramps, the southbound
approach shall be expanded to include an additional left-turn
lane, and the phasing shall be modified to split the eastbound
and westbound approaches.
Interconnect shall be provided between all three signals to
coordinate cycles.
Should a developer construct the improvements, any costs of the
installed improvements in excess of the project’s proportional share, may
be eligible for a TIF fee credit. Any potential TIF fee credit will be
calculated by the City and will comply with any City resolution guiding
TIF Fee credits in place at the time of construction of the
improvements. The developer constructing the improvements may also
