San Diego Has 10 Years of Permitted Reserves Remaining

If the remaining quarries within the County were to produce enough aggregate to satisfy demand; permitted reserves would last less than 10 years.

The figure below shows the location of the quarries throughout San Diego County. In addition, it shows the location of planned highway construction projects. Much of these projects will not start until after 2012. By 2012 more than 50% of the active quarries shown on this map will have closed. Thus, the aggregate needed to construct those projects will need to come from outside the County unless new resources are permitted.


By 2030 only 4 quarries will remain in the County. With a very aggressive highway construction program, it is important to ensure adequate supplies of aggregate are available to build those projects. Without permitting more resources there will not be enough local aggregate resources available to support those projects.
