A more thorough explanation:

Definition: Density zoning is a type of zoning that allows for planned-unit development by modifying lot size and frontage requirements, as long as other land in the development is set aside for public needs like parks or schools. It is also known as cluster zoning.

Example: A city wants to develop a new residential area. Instead of requiring each lot to have a certain size and frontage, they allow for density zoning. This means that some lots may be smaller or have less frontage, but there will be public areas like parks or schools included in the development. This allows for more efficient use of the land and can create a more cohesive community.

Explanation: Density zoning allows for more flexibility in the development of a new area. By allowing for smaller lots and modifying frontage requirements, developers can create a more efficient use of the land. The requirement to set aside land for public needs ensures that the community has access to important amenities like parks and schools. This type of zoning can also create a more cohesive community by encouraging shared public spaces.
