Final answer:
Planning controls for California property are mainly handled by local and state governments, with some federal oversight. The complex history of land grants and zoning affects today's property planning, reflecting the influence of previous and current government policies on the development of regions such as Los Angeles.
Step-by-step explanation:
The level of government currently in charge of planning controls for California property is primarily at the local and state levels, with some influence and overarching regulations set by the federal government. In California, local governments, including city and county authorities, have significant control over zoning, land use, and other planning decisions. The state government also has its regulations and laws that can impact property planning, such as environmental regulations, building codes, and provisions regarding affordable housing. Lastly, the federal government plays a role, particularly in areas that involve federal funding, interstate commerce, or lands managed by federal agencies.
California's property planning history is influenced by many layers of government and policies that have evolved over time. The government policies from nearly a century ago continue to affect neighborhoods today, as observed in the case of Los Angeles where interactive maps show how historical zoning and land division have shaped current urban landscapes. Furthermore, historical land grants, such as the El Encino ranch, highlight the interplay of Spanish, Mexican, and American influences in property distribution and claims.
