The City of Glendora Planning Department has processed an application (Project Number: PLN18-0016), related to the development of a self-storage facility at 919 S. Lone Hill Avenue. The project proposal included text amendments to the City’s General Plan, establishment of site specific development standards, a development plan review, and related environmental review.


The approximately 1.29-acre project site is vacant and void of any buildings or structures; it was a former Caltrans-owned property that has previously been disturbed. The site is bound by major auto dealerships to the south and southeast across a Los Angeles County Flood Control channel (San Dimas Wash) and Lone Hill Avenue; Interstate 210 to the north; a park-and-ride lot to the east, across Lone Hill Avenue; and undeveloped open space and a Metrolink rail line to the west

The City’s General Plan land use designation of the project site is Light Industrial. Per the City’s zoning map, the project site is zoned PR (Planned Redevelopment).


On June 4, 2019, the Planning Commission formally considered the application requests and recommended City Council approval of draft resolutions and an ordinance related to the proposal. On July 9, 2019, the City Council held a public hearing to receive and consider all evidence and reports related to the project application and approved the following requests:

1) Text amendments to the Glendora General Plan to increase the maximum floor area ratio permitted from 0.35 to 2.1 for all properties within the City that have a land use designation of Light Industrial, a zoning designation of Planned Redevelopment (PR), and are bordered on all sides by government-owned land or facilities; and

2) Establish site-specific development standards and permitted uses (e.g. setback, building height and parking standards) for the site located within the PR zone at 919 S. Lone Hill Avenue; and

3) Development Plan Review to allow the construction of a proposed self-storage facility structure and related site improvements on the project site. The facility would include an approximately 40-foot tall building that includes 113,868 gross square feet within three stories, plus a basement level. Vehicular access to the site would be via a new driveway off Lone Hill Avenue, which would connect to an internal east-west drive aisle running the full length of the northern portion of the site from Lone Hill Avenue to the rail line. Access into the self-storage facility would be controlled via computerized access gates.

The City Council will have a required second reading regarding the adoption of the Ordinance establishing the project's site specific development standards on August 27, 2019. 

With assistance from the City's environmental consultant (Placeworks), the City completed an Initial Study of the project in accordance with the California Environmental Quality Act (CEQA). The Draft Initial Study concluded that the project will not have a significant effect on the environment with the inclusion of mitigation measures and a Draft Mitigated Negative Declaration ("MND"), and Mitigation Monitoring Reporting Program were prepared. The public review period for the Initial Study and Draft MND commenced on April 11, 2019, and concluded on May 1, 2019. The Initial Study and Draft MND were also adopted by the City Council on July 9, 2019. 


Construction plans are being prepared by applicant and plans have yet to be submitted to City for Plan Check review for applicable permits from the Building Division and Public Works Departments.
