A project that would transform a golf course into a sand mine in Rancho San Diego is getting pushback. People living in the area are concerned about the impact on the environment and their health.

"It's hard to believe that this project, the application is even being considered by anyone," said Brian Lorenz, who lives one-quarter mile from the proposed project site.
