Land Use Properties Of Concrete Mixing Plants

The Challenges and Benefits of Mixed-Use Facilities

Diversification of uses in mixed-use facilities aids greatly in efficiency. To begin, the land is used more efficiently. "If we were to separate the uses, the traditional, ‘horizontal’ mixed-use communities (where they’re not integrated in one component), are much more land consumptive," says Davis.
