MEMORANDUM
DATE: April 28, 2009
TO: Jamie Rojo, Planning
FROM: Jaimee Bourgeois, Public Works (Traffic)
SUBJECT: New Evolution Fitness Facility CUP - Parking Evaluation
The Applicant of the project is requesting a Conditional Use Permit for a parking reduction and
off-site parking for a health club facility proposed within Parcel A of Enea Plaza. To assess the
feasibility and safety implications of granting such a permit, the City hired Omni Means, a
transportation consultant, to conduct a parking study. The study was completed in February
2009..
Because the project could not provide adequate on-site parking to satisfy the Zoning Ordinance
parking regulations for a health/athletic club, the Parking Study was completed to determine
whether existing parking demand combined with the expected parking demand of the, proposed
health club could be accommodated on-site. The study took into account the concept of "shared
parking"; that is, that parking demand for different uses peaks at different times, resulting in less
total parking required than if all uses peaked at the same timEl. Shared parking opportunity is
analyzed by counting the actual number of parked vehicles each hour over the course of a
typical day. Unoccupied parking spaces at each hourly snapshot are then compared to the
expected parking demand for the health club, which is estimated based on actual data collected
at similar sites.
Following is a brief summary of the study results:
At peak operations, the health club would require 197 parking spaces (this peak occurs
on weekdays around 6:00 p.m.).
At the same time, Parcel A has 131 available parking spaces. Thus, there would be an
on-site deficit of 66 spaces.
The excess demand could be accommodated within the Parcels B-D parking lots.
• If 74 parking spaces on Parcel A are reserved for the existing retail/restaurant businesses
so as not to inconvenience their patrons, then the worst-case on-site deficit would
increase to 108 spaces.
The on-site deficit would not occur only on weekdays at 6:00 p.m. but also at the
following additional times:
o Weekdays at 9:00 a.m. - 23 spaces
o Weekdays at 10:00 a.m. - 80 spaces
o Weekdays at 11:00 a.m. - 51 spaces

o Weekdays at 12:00 p.m. - 15 spaces
o Weekdays at 1:00 p.m. - 8 spaces
o Weekdays at 3:00 p.m. - 8 spaces
o Weekdays at 4:00 p.m. - 61 spaces
o Weekdays at 5:00 p.m. - 84 spaces
o Weekdays at 6:00 p.m.- 108 spaces
o Weekdays at 7:00 p.m. - 63 spaces
o Weekdays at 8:00 p.m. - 33 spaces
o Friday at 6:00 p.m. -- 33 spaces
The excess demand could be accommodated within the Parcels B-D parking lots at each of
these times; however, allowing overflow parking to occur off-site raises several safety concerns
with respect to pedestrian circulation. Although some vehicles parking off-site may be owned by
employees (up to 10 at one time), most would be owned by club patrons. Assuming that the
total parking duration for patrons is approximately 90 minutes, then the expected on-site parking
deficit would result in 356 patrons parking off-site, which equates to 712 pedestrian crossings
across Amador Plaza Road over the course of one day. With such a large volume of
pedestrians crossing Amador Plaza Road, Public Works has thED following concerns:
Some patrons may try to cross mid-block across Amador Plaza Road.
A signalized crossing is available at the Amador Plaza Road/St. Patrick Way intersection.
The eastern leg of the intersection is the 1-680 freeway off-ramp, so motorists are often
traveling at higher speeds as they approach the intersection. Most motorists exiting the
freeway turn right onto northbound Amador Plaza Road and would travel through the
pedestrian crosswalk in which the gym patrons would be crossing. During the weekday
evening peak hour, approximately 400 vehicles make this right turn.
The traffic signal operates with permissive phasing for the eastbound and westbound
approaches; that is, St. Patrick Way and 1-680 off-ramp traffic get a green light at the
same time without protected left-turn phases (i.e., left-turn arrows). Without protected
left-turn phasing, motorists turning from eastbound St. Patrick Way onto northbound
Amador Plaza would travel through the pedestrian crosswalk in which the gym patrons
would be crossing.
Allowing off-site parking if the project is approved would result in a large volume of
pedestrian-vehicle conflicts.
Mr. Enea proposed to the City to build several improvements or incorporate several measures
into the project to help address these safety concerns. Staff has reviewed each and has
determined that they would not adequately respond to the safety concerns. A response to each
proposal is provided in the table on the following page.
Please let me know if you have any questions about Public Works' assessment of the requested
Conditional Use Permit.

Enea P
First, we are proposing, at our sole cost and
expense, to fund the implementation and
construction of an illuminated embedded flashing
light system (embedded in all four sides of the
crosswalk) that would be automatically activated
each time a pedestrian crosses the intersection at
St. Patrick Way and Amador Plaza Blvd.
Second, to further expand on Omni-Means
recommendation we would propose that each new
member of the health club would be required to
review and sign, as part of their membership
agreement, an acknowledgment indicating that
they will agree to park in only designated overflow
parking areas of the center and use only the
crosswalk located at the intersection of St. Patrick
Ways and Amador Plaza Road to access the
Fitness Club from the overflow parking.
Third, signs would be installed in the parking areas
further directing health club members where to and
where not to park. The idea is to keep all overflow
parking as close to the St. Patrick Way / Amador
Plaza Road intersection as possible. This in itself
would deter people from walking across Amador
Plaza Road.
Fourth, although we do not think it would be very
effective, we would agree to construct a barrier
along the west side of Amador Plaza Road
between the first and third driveway entrances.
Fifth, I believe can also pick up about 8 to 9
parking spaces by allowing tandem employee
parking in the current truck loading area. Since
employees working the same shift would come and
go at the same time this does not pose a significant
inconvenience for employees.
While in-roadway warning lights at crosswalks do
have many valuable applications, they are strictly
prohibited for use at controlled crossings, such as
at the signal-controlled intersection of Amador
Plaza Road and St. Patrick Way. This is stated in
the California Manual on Uniform Traffic Control
Devices. This suggested improvement would
therefore not be appropriate.
This proposal is consistent with Omni Means'
recommendation to provide parking location
information to new members and has some merit.
Mr. Enea proposes to extend the
acknowledgement to also cover crossing at the
signalized intersection only. While having
members sign an acknowledgement may
contribute toward their compliance with parking
only in the des gnated areas and crossing only at
the signalized crossing, it does not guarantee that
such behavior will occur. Even with patrons
parking in designated areas and crossing only at
the signal, this would still result in a large number
of patrons having to cross Amador Plaza Road.
Public Works agrees that signage would be
beneficial in communicating the appropriate
locations to park. As stated above, concern
remains about the number of patrons that would
have to cross Amador Plaza Road.
Public Works does not recommend the installation
of a barrier. This would not preclude patrons from
trying to cross at the driveway openings.
Although employees on the same shift generally
arrive and leave at the same time, this type of
parking scenario would likely not be very efficient
or even feasible. If shifts are staggered, then there
is no guarantee that employees of the same shift
only would be parking tandem. More likely, the first
vehicle to arrivE? will be the first to leave, requiring
other employees to leave in the middle of their shift
to move their vehicle.
