Final answer:
Local government officials administer and control the "Subdivision Map Act," which regulates land subdivision to align with public health, safety, and welfare.
Step-by-step explanation:
The "Subdivision Map Act" is administered and controlled by local government officials. The act is a set of regulations in California that governs the division of land and the requirements for the subdivision of real estate. Its primary purpose is to ensure that land is developed in a manner that is consistent with public health, safety, and welfare, including thorough consideration of environmental impacts. Local government officials, such as planning commissions and city councils, administer the act by reviewing and approving or denying proposed subdivision maps according to established local ordinances that are in alignment with the act's requirements. It is important to understand that regulation of development is a significant aspect of local government function, where land-use controls like zoning, subdivision regulation, and building codes come into play. Such processes are closely linked to the official map or master plan of a municipality, guiding future development in structured and sustainable ways.
