What is the General Plan?

The General Plan is the guide for the future social, physical, and economic development of the City. It is comprised of text, diagrams and maps to effectively communicate how the General Plan is to be implemented, and it is a key tool for influencing the quality of life. The plan is a basis for land use decision-making used by policymakers such as the Planning Commission and the City Council.

Beyond serving as “the legal underpinning for land use decisions," the Governor's Office of Planning and Research casts the role of the General Plan in a more aspirational light: "it is a vision about how a community will grow, reflecting community priorities and values while shaping the future.”

Why is a General Plan required?

State law mandates that each city and county in California adopt a “comprehensive, long-term general plan.” The purpose is to plan for important community issues such as new growth, housing needs, and environmental protection. A general plan is used to project future demand for services such as sewer, water, roadways, parks, and emergency services. 

 What goes into the General Plan?

There are both State-mandated and optional “elements,” or chapters, that go into a general plan. These elements make up the framework for decision-making regarding growth and development in the City. State law requires that a general plan address the following seven core topics: Land Use, Circulation, Housing, Conservation, Open Space, Noise, and Safety. The City of Diamond Bar’s General Plan will also include additional elements for Community Character and Placemaking, focusing on urban design and creation of vibrant new spaces; as well as Community Health and Sustainability, focusing on promoting community wellness, meeting the needs of a changing population, and sustaining the city equitably, fiscally, and environmentally.

 Why is the Plan being updated?

Diamond Bar’s existing General Plan was adopted in 1995, and now needs to be comprehensively reexamined to ensure that it reflects the city’s goals and priorities for the next 20 years. Many of the objectives of the existing General Plan have been met, and new opportunities and challenges have arisen. A new plan is needed to manage Diamond Bar’s future growth, revitalize key opportunity sites, attract high quality businesses and jobs, protect natural resources, promote high quality design of buildings and public spaces, maintain public safety and municipal services, and accommodate the needs of an aging population – all of which contribute to the quality of life that residents have come to expect. A comprehensive update to our General Plan will enable us to proactively and opportunistically guide the City through another 20-year cycle of growth and change.

What is an Environmental Impact Report (EIR)?

An environmental impact report is a detailed analysis of the environmental effects of a plan or development project. The EIR identifies alternatives to the proposed project and presents ways to reduce or avoid environmental damage. Under the California Environmental Quality Act (CEQA), a general plan is considered a “project,” and thus requires that an EIR be completed in conjunction with the plan. Community members can provide input at two different phases in the EIR process: in response to the Notice of Preparation (NOP), which declares that an EIR is going to be prepared, and to the Draft EIR itself.

What is a Climate Action Plan (CAP)?

​A CAP is a roadmap that outlines policies, programs and implementation strategies designed to reduce a city’s GHG emissions. CAPs are made up of three broad components: an inventory of current emissions, GHG targets and forecasts, and corresponding GHG mitigation measures. Read more about CAPs here
