How We Got Here
In 2019, the City Council adopted the Diamond Bar General Plan 2040. During the process, we learned that residents felt Diamond Bar lacked a clear community focal point and wanted a vibrant, walkable downtown—similar to many of our neighbors.
The City is working with the community to plan the creation of an inviting Town Center, envisioned to feature pedestrian-only plazas and paseos lined with shops, restaurants, entertainment venues, community gathering spaces, and urban living opportunities.
TAP
Report
In 2021, the City engaged the Urban Land Institute – Los Angeles Chapter (ULI-LA) to assemble a Technical Assistance Panel (TAP) to study the area and make recommendations for design considerations, local policy changes, and investments needed to make the Diamond Bar Town Center a reality.
Specific Plan
In 2022, the city engaged Torti Gallas + Partners in Los Angeles, to create the Town Center Specific Plan. After a robust public outreach process, including a week-long design “charrette”, the Torti Gallas team, developed a Public Review Draft of the Town Center Specific Plan, including Objective Design Standards and other implementation mechanisms to bring the plan to fruition.
