Dear Mr. Hofhian: Woodland Hills
Linscott, Law & Greenspan Engineers has prepared the following pickup / drop off.
assessment for the proposed Element Education School project, located at 6797
Embarcadero Lane, Suites A-C, within the Bluwater Crossing development in the
City of Carlsbad. This study focuses on assessing the vehicular circulation associated
with the pickup and drop off (loading) of students along Embarcadero Lane. Since
the project will provide the option of curbside pickup / drop off as well as loading
parking spaces, this study assesses both loading options.
PROJECT DESCRIPTION
The Element Education School project proposes to develop an 11,617 square foot
school / daycare facility to accommodate a maximum of 220 students with 18 staff.
The project will offer three distinct educational programs for children and students of
varying ages: My Element Montessori; Community Montessori; and Dehesa Charter
School.
Loading vehicles will access Embarcadero Lane via Avenida Encinas from the south,
pick up or drop off children / students using either the curbside service or the Philip MUnSCOt1.PE(IS2.}
provided loading parking spaces and depart Embarcadero Lane to the north. The staff Jack M. Greenspan, PEmoo
facilitated curbside service will be offered to parents required to sign younger William A. Law, PEIRetI
children and students into and out of daycare / school, as an alternative to parking, as Paul W. Wilkinson, PE
well as to parents of older students who wish to load at the curb. John P. Keating, PE
David S. Shender, PE
John A. Boatman, PE
The project will provide a total of 22 assigned parking spaces for staff (six within the Clare M. Look-Jaeger, PE
underground parking garage and 16 on Embarcadero Lane, south of the loading Richard E, Barreno, PE
spaces) and ten 15-minute parking spaces on Embarcadero Lane for student loading Keil 0. Maberry, PE

north). Figure 1 shows the project's site plan and parking designations on
Embarcadero Lane.
The project's three educational programs will be located within the same building of
the existing Bluwater Crossing development and will offer flexible pickup and drop
off times and staggered start and end times. The existing facility is currently vacant.
The three programs are described further below:
My Element Montessori (Suite A) daycare center will serve a maximum of 72
children, ages three to five, at any one time in three classrooms (24 students
per classroom) with a total of eight staff. Classroom I will offer two half day
programs, one in the morning and One in the afternoon. Classroom 3 will offer
an extended day program with flexible start and end times. The start and end
times of the three classrooms will be staggered. Parents will have the option of
picking up and dropping off their children by either utilizing the provided
curbside loading service or parking in one of the ten 15-minute parking spaces
provided on Embarcadero Lane. The proposed My Element Montessori
classroom schedules are summarized below in Table A. Pickup and drop off
times will be strictly monitored and enforced and parents who arrive early will
be instructed to return during the designated pickup time assigned for their
child's classroom.

five to twelve, in three classrooms (32 students per classroom) with a total of
seven staff. Classroom 3 will offer an extended day program with flexible
start and end times. The start and end times of the three classrooms will be
staggered. Parents will have the option of picking up and dropping off
students by either utilizing the provided curbside loading service or parking in
one of the ten 15-minute. parking spaces provided on Embarcadero Lane. The
proposed Community Montessori classroom schedules are summarized below

Dehesa Charter School (Suite B) will serve a maximum of 52 middle and
high school students with a total of three staff. Hours of operation will be
between 9:00 AM and 4:00 PM. Core classes will be offered on Mondays and
Wednesdays, tutoring labs will be offered on Tuesdays, and electives will be
offered on Thursdays. All classes offered are optional and intended to
supplement other off-site educational programs, most specifically home
schooling. As such, students may enroll in as many or as few classes as they
would like.
Dehesa Charter School students are expected to get to school by either getting
picked up / dropped off, using public transit or driving themselves. Use of
public transportation, especially the nearby Coaster Station (approximately 0.1
miles away, or a three-minute walk) will be encouraged. Designated parking
for the students of Dehesa Charter School will not be provided, and all non-
designated parking within the Bluwater crossing development will be limited
to three-hours. Since no designated student parking will be provided it was
estimated that 5% of the Dehesa Charter School students would drive their
own vehicles to school (with 75% being picked up / dropped off and 20%
using transit). This equates to approximately three (3) students who are
expected to park either in the time restrictive non-designated parking within
the Bluwater crossing development or along Avenida Encinas. No designated
crosswalks are provided within the immediate vicinity of the Project either
along Embarcadero Lane or Avenida Encinas and students will be encouraged
to exercise caution as they make their way from their cars to school. For
students getting picked up or dropped off, parents will have the option of

utilizing the provided curbside loading service or parking in one of the ten 15-
minute parking spaces provided on Embarcadero Lane.
PROJECT TRAFFIC LOADING ESTIMATE
A site specific trip generation was developed given the project's three unique
educational programs with staggered start and end times and flexible pickup and drop
off times. A standard project trip generation using rates from the SANDAG (Not So)
Brief Guide of Vehicular Traffic Generation Rates for the San Diego Region is
included in Attachment A for reference.
The number of vehicles expected during loading operations were calculated every
fifteen minutes for peak loading times during the AM and PM hours based on the
total number of children / students, program start and end times, and an estimated
child or student per vehicle factor (1 child per vehicle for My Element Montessori
attendees and 1.5 children per vehicle for Community Montessori and the Dehesa
Charter School attendees). It was estimated that 100% of My Element Montessori and
Community Montessori attendees would participate in loading operations and that.
75% of Dehesa Charter School attendees would participate in loading operations,
with the remaining 20% using transit and 5% driving themselves. Given the unique
operating characteristics of the Dehesa Charter School where student attendance is
not required, 80% student attendance was assumed. The results are summarized in
Table C. As shown in Table C, peak loading is expected between 8:00 and 9:00 AM
with 110 total loading vehicles and between 2:45 and 3:45 PM with 78 total loading
vehicles.
The number of loading vehicles summarized in Table C was used to assess the
project's loading operations. Since the project will provide the option of curbside
pickup / drop off as well as 15-minute loading parking spaces, this study assesses
both loading options. As shown on Figure 1, Zone A: Curbside Pickup / Drop off,
located within the traffic circle, on Embarcadero Lane, will provide space for
approximately three loading vehicles. This area will be suitably identified as an active
loading zone with the appropriate curb markings and / or signage. Zone B: Pickup /
Drop off Parking, primarily located just south of Zone A (with one space located just
north of Zone A) will provide a total of ten 15-minute parking spaces for parents who
wish to park and accompany their child into or out of school. Loading operations for
both Zone A and Zone B are assessed below.
LOADING ASSESSMENT - ZONE A: CURBSIDE PICKUP! DROP OFF
As mentioned above, Zone A, located within the traffic circle on Embarcadero Lane,
will provide space for approximately three loading vehicles for parents who wish to
N:2396\Repert'EIement Education Loading Study_Revised Feb 2015 Final_Clean.docx
Mr. Bill Hofman
February 24, 2015
Page 5
utilize the curbside loading service. Thru traffic will be able to traverse the traffic
circle mostly unimpeded by vehicles utilizing the curbside loading service.
During AM drop off operations, 60% .of My Element Montessori loading vehicles
were assumed to utilize the curbside loading in Zone A (with the remaining 40%
parking as discussed further in the following section), with each vehicle requiring an
average of approximately two minutes of curbside drop off time. In order to account
for longer processing times associated with PM pickup operations caused by some
parents arriving early and having to wait for school to get out, 50% of My Element
Montessori loading vehicles were assumed to utilize the curbside loading in Zone A
(with the remaining 50% parking in Zone B as discussed further in the following
Section), with each vehicle requiring an average of approximately three minutes of
curbside pickup time. It was assumed that parents who arrive early would be more
likely to park rather than wait in the curbside Zone A. It should, be noted that the
pickup and drop off operations will be strictly monitored and enforced and most
parents who arrive early will be instructed to return during the designated pickup time
assigned for their child's classroom.
Similarly, during AM drop off operations, 70% of Community Montessori loading
vehicles were assumed to utilize curbside loading in Zone A (with the remaining 30%
parking), with each vehicle requiring an average of approximately one minute of
curbside drop off time. In order to account for longer processing times associated
with PM pickup operations caused by some parents arriving early and having to wait
for school to get out, 60% of Community Montessori loading vehicles were assumed
to utilize curbside loading in Zone A (with the remaining 40% parking in Zone B),
with each vehicle requiring an average of approximately two minutes of curbside
pickup time. It was assumed that parents who arrive early would be more likely to
park rather than wait in the curbside Zone A. Again, pickup and drop off operations
will be strictly monitored and enforced and most parents who arrive early will be
instructed to return during the designated pickup time assigned for their child's
classroom.
All of the Dehesa Charter School loading vehicles were assumed to use Zone A, with
each vehicle requiring an average of approximately one minute of curbside loading
time for drop off and two minutes for pickup.
Based on these assumptions, and the three loading stalls provided within the traffic
circle, a curbside loading assessment was conducted as summarized in Table D. As
shown in Table D, the Zone A demand is not expected to exceed the calculated
capacity, which could result in loading vehicles blocking the adjacent 15-minute
parking to the south, except between 8:00 and 8:15 AM when the demand exceeds
N:2396ReportEIement Education Loading Study_Revised Feb 2015 Final_Clean.docx
Mr. Bill Hofman
February 24, 2015
Page 6
capacity by three vehicles due to both My Element Montessori and Community
Montessori students loading at this time. However, this demand exceedance is
minimal and only expected between 8:00 and 8:15 AM. Furthermore, parents will
likely opt to use the 1 5-minue spaces in Zone B when Zone A is full. Therefore, Zone
A is not expected to adversely affect vehicular circulation on Embarcadero Lane or
impede Zone B loading. Furthermore, in no case are loading operation queues from
Zone A expected to extend to the assigned residential parking spaces, just south of
Zone B, or to the driveway leading to the adjacent apartment complex.
LOADING ASSESSMENT -ZONE B: PICKUP! DROP OFF PARKING
Zone B, primarily located just south of Zone A on Embarcadero Lane, will provide a
total of ten 15-minute parking spaces for parents who wish to park and accompany
their child into school. During AM drop off operations, 40% of My Element
Montessori loading vehicles were assumed to utilize Zone B, with each vehicle
requiring an average of approximately six minutes of drop off time. In order to
account for longer processing times associated with PM pickup operations caused by
some parents arriving early and having to wait for school to get out, 50% of My
Element Montessori loading vehicles were assumed to utilize Zone B, with each
vehicle requiring an average of approximately ten minutes of pickup time. It was
assumed that parents who arrive early would be more likely to park rather than wait
in the curbside Zone A. It should be noted that the pickup and drop off operations will
be strictly monitored and enforced and most parents who arrive early will be
instructed to return during the designated pickup time assigned for their child's
classroom.
Similarly, during AM drop off operations, 30% of Community Montessori loading
vehicles were assumed to utilize Zone B, with each vehicle requiring an average of
approximately four minutes of drop off time. During PM pickup operations, 40% of
Community Montessori loading vehicles were assumed to utilize Zone B, with each
vehicle requiring an average of approximately eight minutes of pickup time. All of
the Dehesa Charter School loading vehicles were assumed to use Zone A, and were
therefore not included in the Zone B assessment.
Based on these assumptions, and the ten loading spaces provided, a parked loading
assessment was conducted as summarized in Table E. As shown in Table E, peak
Zone B demand is expected between 8:00 and 8:15 AM when both My Element
Montessori and Community Montessori students are loading. During this time the
loading demand was calculated at 15 vehicles with a capacity of 25 vehicles.
Therefore, Zone B is not expected to adversely affect vehicular circulation on
Embarcadero Lane and the parking demand is not expected to exceed the capacity.
N:2396Repon'EIement Education Loading Study_Revised Feb 2015 Final_Clean.docx
Mr. Bill Hofman

Furthermore, excess loading parking is expected to be available should Zone A
exceed capacity as detailed above.
SPECIAL EVENTS
Each of the project's three educational programs are expected to host special events
approximately twice a semester. These special events could include an open house,
parent teacher conferences, or student performances. The majority of the special
events will be held during the early evening hours. The three educational facilities
have agreed not to host special events concurrently with each other to minimize the
parking demand. A majority of the reserved staff spaces will be made available to
parents along with the Zone B loading spaces during these special events. Any
additional parking need can be accommodated on Avenida Encinas. A cursory
assessment found approximately 130 on-street parking spaces on Avenida Encinas
within a quarter-mile of the Project. Therefore, given the above, Project's limited
number of special events are not expected to result in parking problems.
CONCLUSIONS AND RECOMMENDATIONS
No significant pickup / drop off loading operation issues were identified in
association with the proposed project, either in Zone A or Zone B. Therefore, it is
expected that the project will not impede vehicular circulation or parking on
Embarcadero Lane.
It is recognized that certain assumptions were required to conduct this analysis.
Therefore, to further ensure efficient and safe loading operations the following are
recommended:
Pickup and drop off operations should be strictly monitored and enforced.
Parents who arrive early for pickup should be instructed to return during the
designated pickup time assigned for their child's classroom, as needed. In
addition, monitors should ensure that loading vehicles do not block residential
parking spaces or the adjacent intersection just south of the school. Should
issues arise such as congestion or inefficient loading, the project should
consider staggering start / dismissal times above what is currently proposed
and / or provide additional flexible pickup / drop off times.
The curbside loading service assumed in this study must be provided to ensure
the project will not impede vehicular circulation or parking on Embarcadero
Lane. Curbside loading should be adequately attended to by staff members or
parent volunteers during peak pickup / drop off times to ensure that the
loading times assumed in this assessment are maintained.

The staggered start / dismissal times and flexible pickup / drop off times as
noted in this report must be implemented to ensure the project will not impede
vehicular circulation or parking on Embarcadero Lane.
The loading circulation plan (access Embarcadero Lane from the south and
depart to the north) should be enforced to prevent loading vehicles from
utilizing parking on the west side of Embarcadero Lane and to prevent
children and students from crossing Embarcadero Lane.
The use of transit whenever possible by appropriate age groups should be
encouraged.
