TOP 2050 Update

The City is conducting a technical update to TOP!

The Ontario Plan was and still is a groundbreaking approach to comprehensive planning. TOP is a “Business Plan” connecting a long-term strategic vision to fiscal sustainability, aligned with budget and daily operations, and a clear framework for implementation. TOP ultimately is a “Plan of Action” that requires the City to update its provisions periodically and is the chief guiding document for all City decisions.

Guided by new leadership, Ontario is taking the opportunity to revisit and refine the Plan. The City is focusing on conducting technical updates to conform with state law (housing, community health, environmental justice, climate adaption, and mobility), bringing long-term growth and fiscal projections into alignment with current economic conditions, and advancing the Tracking and Feedback component and Implementation Plan.

Get Involved with the TOP Technical Update!

Over the last few years, the City has led public outreach efforts for various neighborhood initiatives, citywide plans, housing needs and fair housing assessments, and community projects, such as the Transformative Climate Communities (TCC) program, Recreation and Parks Master Plan, Active Transportation Master Plan, and others.

The TOP technical update builds upon the input we have already received from the community and continues the conversation in an ongoing effort to communicate with the community about the five topics driving the TOP update (web based maps).
