Pacific Aggregates, Inc., produces sand and gravel products for use in making concrete.

Shifts run through the day and night. In late November, 2009, the plant instituted a complete closure between midnight and 3 a.m., after which a maintenance shift comes on.

In 2010, on-site plant tours for the public will be scheduled as outreach continues. On the Web, visit or e-mail

Operations include heavy rolling stock to push and move gravel and sand. Hard rock material is mined locally in Lake Elsinore.

Weather station used to regulate operation under variable conditions

An onsite weather monitoring system tracks wind and other data that can result in a plant shut down, such as when winds that can carry fugitive dust exceed 25mph.

If fugitive dust or other air quality problems are observed, the public should telephone AQMD immediately to report it. The toll free phone number is 1-800-CUT-SMOG.

RIGHT:  All trucks must exit over a track out device (think industrial strength washboard), which loosens and removes debris that would otherwise be deposited along the path of travel. Pacific Aggregates has over 1500 feet of paved roadway onsite for added dust control.

Recent improvements to Lake Street will require all trucks to make a right turn entry into Pacific Aggregates from Lake Street (across from Alberhill Community Park), and exit only at the new intersection and traffic signal at Nichols Road and Lake St.
