PROJECT TITLE: Diamond Bar Town Center Specific Plan (Project) PROJECT LOCATION: The Planning Area is bounded north by the Pomona Freeway (SR60), on the east by a neighborhood of singlefamily homes, on the south by Golden Springs Drive, and on the west by Prospectors Road and the Fall Creek private residential condominium community. PROJECT APPLICANT/ LEAD AGENCY: City of Diamond Bar, Community Development Department PROJECT DESCRIPTION : The proposed Diamond Bar Specific Plan (Project) would establish a regulatory framework to guide the transformation of approximately 45 acres of existing suburbanstyle retail shopping centers into a pedestrianoriented downtown, or Town Center, providing housing opportunities, retail, restaurants, and entertainment uses within the City of Diamond Bar. The Project is anticipated to result in the development of up to 2,055 housing units (an increase of 705 units); 200 hotel rooms (an increase of 103 rooms); 40,000 square feet of public open space (an increase of 40,000 square feet); and 446,000 square feet of commercial space (a net decrease of 64,000 square feet), including retail, dining, and entertainment uses, as compared to development anticipated for the area under the General Plan, as amended by the 2022 Housing Element Update. The proposed increase in density is consistent with the major conclusions of the Urban Land Institute Los Angeles Technical Assistance Panel (TAP) report, which found that higher residential densities are appropriate for achieving a viable, mixeduse Town Center. The Project would also include supporting infrastructure and development standards implemented through adoption of the Specific Plan and associated entitlements. The Project includes concurrent legislative actions consisting of a General Plan Amendment and zoning map and text amendments. These actions would revise the General Plan land use designations and the zoning applicable to the Project Planning Area as necessary to ensure consistency with, and implementation of, the Specific Plan's framework, including maximum residential density and permitted uses. ENVIRONMENTAL DETERMINATION: Pursuant to the provisions of the California Environmental Quality Act (CEQA), the City prepared a Draft Supplemental Environmental Impact Report (SIR) for the proposed Project. The environmental analysis evaluated the Project and provides a supplement to the Diamond Bar General Plan 2040 Certified EIR, as amended by an Addendum to the Certified EIR that was adopted for the City's 20212029 Housing Element Update (on August 11, 2022). Outreach efforts to solicit citizen and public agency input throughout the SIR process included the following actions: Notice of Preparation: The City submitted a Notice of Preparation (NOP) to the California Office of Planning and Research State Clearinghouse (SCH) on June 5, 2023, informing the agency of the City's intent to prepare an SIR for the Proposed Project. The City concurrently advertised the NOP on the City's Town Center website ( www.downtown4db.com and circulated it to public agencies and members of the public to solicit input in defining the scope of the SIR. A 30day public comment period comments on June 5, 2023, and ended on July 5, 2023. Scoping Meeting: A public scoping meeting to facilitate public input was held at the Diamond Bar City Hall Windmill Community Room on June 8, 2023. Draft SIR: The Draft SIR was published and made available for review and comment by public agencies and the public at large for a 45day period that commenced on August 25, 2025, and concluded on October 10, 2025. A Notice of Completion/Availability (NOA) was concurrently submitted to the SCH and posted on the project website. Final SIR: The Final SIR, incorporating comments and responses to the Draft SIR will be completed and posted on the project website on January 30, 2026. Responses to comments will also be sent to commenting agencies and organizations on the same date. At the hearing, the City Council will consider whether to certify the SIR, adopt the mitigation monitoring and reporting program, and adopt the Statement of Overriding Considerations.
