Map Sheet 52
Aggregate Availability in California

Map Sheet 52 (scale 1:1,100,000), by Susan L. Kohler, 2002, compares the forecasted 50-year demand for construction aggregate to the currently permitted construction aggregate resources for 32 resource areas in California. The 26-page report that accompanies the map sheet contains information on aggregate resources (production, price, transportation, quality and use, comparison of sand and gravel to crushed stone, and factors affecting aggregate demand). Below is a portion of Map Sheet 52.

 

 

Map Explanation

The purple and blue pie diagrams show fifty-year aggregate demand compared to current permitted aggregate resources for each aggregate study. The actual 50-year demand tonnage is shown on the map located next to the pie diagram. Red halos around the pie diagrams represent aggregated study areas with less than 10 years of permitted aggregate resources remaining.

Aggregate production areas are shown on the map as black triangles. The relative size of each symbol corresponds to the amount of yearly production for each mine or group of mines.
