Which type of plan aims to prevent conflicts between competing land uses, such as a daycare next to an oil refinery?

The correct answer is a land use plan. This type of plan is specifically designed to manage and regulate how land is utilized in a given area, ensuring that incompatible land uses are separated to prevent conflicts and enhance the quality of life for residents. For instance, placing a daycare next to an oil refinery could pose significant safety risks and diminish the daycare's viability due to noise, air quality, and traffic concerns.

A land use plan typically involves zoning regulations, which delineate areas for specific activities (residential, commercial, industrial, etc.) and establish buffers or transition areas to minimize adverse impacts. This planning approach is critical in urban development, where competing interests and land uses coexist.

Other types of plans, such as speculative plans, vision/framework plans, and site master plans, serve different purposes. Speculative plans often arise from assumptions about potential future development without firm commitments. Vision/framework plans outline broad goals and aspirations for an area but do not provide the detailed regulations necessary to prevent land use conflicts. Site master plans focus more on the layout and design of a particular site rather than the interrelations of land uses in the broader context.
