The Eocaya Self-Storage project is located within the Village 3 North Business Park. The Project proposes toconstruct 12S,80SSFofself-storage and a1,192SFsupporting office. The City ofChula Vista Municipal Code, Chapter 19.62 and the Village 3 North Planned Community District Regulations,Section Vill. Parking Regulations, do not include a category for "oe|f'otoragefad|itieo." Therefore, it is more appropriate and reasonable to apply the provisions outlined in the PC District Regulations, Section VIII.B.7. which states: "The parking requirement for uses not specifically listed /n the matrix shall be determined by reference to CVMC Chapter 19.62(Off-Street Parking and Loading), or if not included therein, the approving authority may determine the parking requirement for the proposed use based on the basis ofrequirements for similar uses, and unany trgficengineering and planning data that is appropriate tuestablishment ofominimum requirernent.^ Per the PC District Regulations,several other sources were considered to determine the minimum parking requirement for the Project. Minimum parking requirement were obtained from the City of San Diego Municipal Code, as well as the Institute of Transportation Engineers (ITE) Parking Generation 4th Edition manual. Excerpts from the parking requirement sources are provided in Attachment A. Table 1 applies these minimum parking requirements tothe Project.

The Project proposes to provide 21 total parking spaces, which exceeds the minimum number of parking spaces calculated per the parking requirements presented in Table 1. As such, the total parking spaces provided are sufficient for the Project land use and no additional parking spaces would be needed.

They are typically referred to as"self-storage"facilities. Each unit is physically separated from ' other units, and access is usually provided through an overhead door or other common access point. Database Description • Average parking supply ratio: 0.2 spaces per 1,000 square feet (sq. ft.)gross floor area (GFA) (two study sites). The Saturday parking demand ratio for a site with 1,400 storage units was 0.77 vehicles per 100 � - storage units. Parking demand data at this site were collected for six consecutive hours between 1:00 and 7:00 p.m., and the peak period of demand occurred between 4:00 and 5:00 p.m. The following table presents a time-of-day distribution of parking demand for three study sites.
