Suiriect Millenia — Alexan Project
Linscott, Law & Greenspan, Engineers (LLG) has prepared this memorandum to
summarize the results of a parking and traffic circulation assessment for the Alexan
project. The project proposes the construction of the following land uses on Parcels 3,
5 and 6, located within the Millenia development in the City of Chula Vista:
• 294 apartment units
• 3 townhomes
• 12 live /work units (12 townhomes + 4,200 square feet (SF) of retail space)
• 2,084 SF of restaurant space + 282 SF of outdoor seating
• 4,467 SF of commercial space
Figure .1 illustrates the project location.
Attachment contains the project site plan.
Parking Assessment
The Urban Land Institute (ULI)'s Shared Parking, 2nd Edition reports the following
parking demand rates for the corresponding project land uses:
WeekdaRates
■ Residential (rental) =1.65 spaces / unit
■ Residential (owned) = 1.85 spaces / unit
■ Family Restaurant = 10.5 spaces / 1,000 SF
■ Community Shopping Center ( <400,000 SF) = 3.6 spaces / 1,000 SF
Weekend Rates
• Residential (rental) = 1.65 spaces / unit
• Residential (owned) = 1.85 spaces / unit
• Family Restaurant = 15.0 spaces / 1,000 SF
• Community Shopping Center ( <400,000 SF) = 4.0 spaces / 1,000 SF
To determine the total parking required for the project, the ULl parking demand rates
listed above were applied to the corresponding project land uses and summed
together for both the weekday and weekend scenarios. The total parking required is

the maximum between the weekday and weekend scenarios. As a result, the
calculated parking demand for the project is 586 spaces.
Attachment B contains a breakdown of the parking demand calculations.
It should be noted that the calculation is conservative as it does not account for any
parking reductions due to the live -work component of the project, the application of
parking strategies such as improving walkability, bikeability, and access to Bus Rapid
Transit (BRT), and the long -term synergy between land uses within Millenia. If these
factors are taken into account, the calculated parking demand would be reduced to
452 spaces.
Attachment C contains more information on the parking reduction factors and the
right -sized parking demand calculations.
The project proposes to provide 606 parking spaces (483 on -site and 123 on- street)
which is more than the required parking per the ULI rates. Section 03.15.002 of the
form based code states that "all available on- street parking shall be counted towards
satisfying a project's total required parking."
rfa !cCirculafion
LLG assessed several components pertaining to the traffic circulation of the proposed
project. The traffic volumes reported in the Addendunr to the Focused Buildout
Ti affic study for the Proposed Eastern Urban Center dated May 15, 2008, were
utilized in our evaluation. It should be noted that the above study assumed the project
lots generate approximately 6 times more traffic than the anticipated project trip
generation. Attachment D contains the excerpts of the addendum.
Based on our review of the traffic volumes and proposed roadway and intersection
configurations depicted in the project site plan, all the driveway intersections are
estimated to operate at acceptable level of service.

a. Because the five -work units are residentially- driven (commercial sF < 50% of live-work GFA), a rate of 1.85 1du was utilized.
b. For outdoor dining areas, up to 200 s.f, is exempt from minimum parking requirements. Above 204 s.f., a minimum of 5 spaces per ksf should be provided.
c. A shared parking analysis based on the UU methodology was conducted to determine the reduction factor
d. The implementation of the following long -term parking strategies were assumed. The reduction factor were obtained from the Millenia PMP report:
1. Access to Bus Rapid Transit
2. Improve walkability,
3. Improve blkeability
4. Improve user information and marketing
