Milton Fonseca

Fifty-Year Aggregate Demand Compared to PermittedAggregate Reserves*The pie charts show the projected 50-year demand foraggregate as of January 2011 compared to currentlypermitted aggregate reserves (in short tons). The 50-yeardemand for a particular study area is graphically representedby one of four pie diagram sizes. Study area boundaries areshown on the index map of aggregate studies (lower left).* Permitted aggregate reserves are those portions of the resources for which local lead agencies(counties and cities) have issued mining permits. Non-permitted aggregate resource informationis given in each aggregate study report. See accompanying text for references to these reports.

LEGEND50-year demand that will not be met by existingpermitted reserves.Permitted aggregate reserves.50-year demand is 25 to 200 million tons.

50-year demand is > 200 to 500 million tons.

50-year demand is > 500 to 800 million tons.

50-year demand is more than 800 million tons.

50-year demand for aggregate is 100 million tons;permitted resources total 25 million tons of the50-year demand.

25/100 Million Tons (permited reserves/ 50-year demand)17 to 20 Years (years of permitted reserves remaining)

50-year demand for aggregate is 510 million tons;permitted reserves are greater than or equal to the50-year demand.

550/510 Million Tons (permited reserves/ 50-year demand)More Than 50 Years (Years of permitted reserves remaining)

Examples

< 0.5 Million Tons per Year

> 0.5 - 1.5 Million Tons per Year

Map Usage and LimitationsThis map is intended to provide general information about the current availabilityof California's permitted construction aggregate reserves to state, regional, andlocal land-use planners and decision-makers. It is designed to assist planningagencies in considering construction aggregate needs in the regional planningprocess. However, the map is not intended to be used as the sole source ofinformation about construction aggregate availability, or as the basis for site-specific land-use decisions. Although the statewide and regional information onthis map may be useful to local decision-makers, the more detailed informationcontained in the referenced aggregate studies should be used for local land-usedecision-making purposes.
