SUBJECT: CARLSBAD RANCH PA~S RESORT
As you requested, Urban Systems associates, Inc. has prepared an evaluation of the Interstate
5/Cannon Road interchange based on both existing 2003 conditions and buildout conditions as
included in the Final Environmental Impact Report for Carlsbad Ranch.
As a result of our evaluation, it can be concluded that:
0 The current peak hour operations at the I-5/Cannon Road interchange ramps are
at levels of service "A" or "B" so that adequate reserve capacity would be available
as the Carlsbad Ranch Resort is constructed without the need for interchange
improvements.
0 The buildout peak hour conditions are expected to be at LOS "D" at the I-5/Cannon
Road ramps without the need for interchange improvements.
0 At buildout, the peak hour conditions at the I-5/Cannon Road interchange are
expected to be at or slightly greater than the 1,500 ILV/HR value that Caltrans
typically uses for design purposes, so that no additional interchange improvements
should be needed through buildout of the City of Carlsbad, including the Carlsbad
Ranch Resort.
Provided below is a discussion of our evaluation:
BUILDOUT FORECAST COMPARISON
The buildout scenario included in the approved Carlsbad Ranch FEIR was based on volumes
provided from the SAN DAG Regional Traffic Model in use at the time of DEIR preyaration, plus
a manual addition of project only traffic from LEGOLAND, since the theme park is a unique
traffic generator. The Regional Traffic Model included the buildout of the City of Carlsbad

General Plan as background traffic. The Year 2020 was assumed as the time frame for the City
of Carlsbad buildout.
The current SANDAG Regional Traffic Model assumes Year 2030 as the design time frame.
However, the previously approved Year 2020 traffic model results are still valid for use in the
evaluation of the Carlsbad Ranch Resort since the recent economic slowdown and slow growth
caused by the economic conditions have extended the design time frame of the traffic model.
An evaluation of the traffic growth rate from Year 2003 to Year 2030 using the approved
Carlsbad Ranch FEIR peak hour projects for buildout indicate that the total growth in approach
volumes at the I-5/Cannon Road interchange is approximately 3.8% per year in the AM peak
hour and 3.1 % per year in the PM peak hour. These growth rates per year are higher than the
approximately 3% growth per year typically assumed when using a "straight-line growth rate"
to predict future traffic volumes. Therefore, the approved FEIR buildout peak hour volumes are
appropriate for use for this evaluation.

The current proposed resort is within the land use assumptions assumed in the approved FEIR
for the Carlsbad Ranch. The table below shows a comparison of the land use assumptions to the
current project.

The similarity of land use to the approved FEIR also applies to the traffic assumptions so that
the project traffic contribution to the I-5/Cannon Road interchange will not change.
EXISTING PEAK HOUR LEVELS OF SERVICE
Attachment 2 includes AM and PM peak hour traffic volumes and levels of service calculations
for the I-5/Cannon Road interchange ramp intersections for current conditions.
The levels of service and capacity utilization percentages are summarized below:

As shown in this table, adequate reserve capacity (up to 90% of capacity equals LOS "D") exists
for the addition of background traffic plus resort traffic without the need for interchange
improvements.

on the buildout peak hour volumes included for the approved EIR analysis.

AM 87% D 89% D
PM 78% C 84% D
As indicated above, acceptable levels of service are expected through buildout without the need
for interchange improvements.
CALTRANS DESIGN VOLUMES AT BUILDOUT
The Caltrans design volumes at interchange ramps typically are at 1,500 Intersecting Lane
Vehicles Per Hour (ILV(HR). An ILY(HR calculation for the current lane configurations and
current peak hour volumes total 1,084-ILV (HR in the AM peak hour and 1,049 ILV (HR in the PM
peak hour. Therefore, reserve capacity exists at the interchange that can accommodate future
traffic including project traffic without the need for additional lanes at the ramp intersections.
Attachment 4 shows the existing conditions ILV(HR calculations.
An ILY(HR calculation for buildout peak hour volumes assumed in the approved FEIR indicates
the interchange would accommodate 1,538 ILV(HR in the AM peak hour and 1,528 ILV(HR in
the PM peak hour under buildout conditions with no additional lanes at the ramp intersections,
as summarized in Attachment 5.

CONCLUSIONS
Urban Systems Associates, Inc.
The current 1-5/Cannon Road ramp intersections operate acceptably and with reserve capacity
by both City of Carlsbad and Caltrans criteria so that project traffic can be added with no
interchange improvements needed.
At buildout, using peak hour volumes contained in the approved Carlsbad Ranch FEIR, the 1-
5/Cannon Road interchange ramps are expected to operate acceptably and within the City of
Carlsbad Growth Management Program requirements of no worse than LOS "D" during peak
hours, with no additional lanes needed at the interchange.
Also at buildout, the I-5/Cannon Road interchange is expected to operate at or near the Caltrans
design volume for a tight diamond interchange without the need for additional lanes at the
intersection.

* All level of service measurements are pased upon HCM procedures for peak-hour conditions.
However, VIC ratios for Roadway Segments may be estimated on an ADT/24-hour traffic volume
basis (using Table D-2 or a similar LOS chart for each jurisdiction). The acceptable LOS for
freeways, roadways, and intersections is generally "D" ("C" for undeveloped or not densely
developed locations per jurisdiction definitions). For metered freeway ramps, LOS does not
apply. However, ramp meter delays above 15 minutes are considered excessive.
** If a proposed project's traffic causes the values shown in the table to .be exceeded, the impacts
are determined to be significant. These impact changes may be measured from appropriate
computer programs or expanded manual spreadsheets. The project applicant shall then identify
feasible mitigation (within the Traffic Impact Study report) that will maintain the traffic facility at
an acceptable LOS. If the LOS with the proposed project becomes unacceptable (see above *
note), or if the project adds a significant amount of peak-hour trips to cause any traffic queues to
exceed on-or off-ramp storage capacities, the project applicant shall be responsible for
mitigating significant impact changes.
*** See Exhibit D-2 for ramp metering analysis.
