Most notable <br />is the surrounding communities' future gravel, asphalt and concrete needs. Other factors include: <br />^ Local, State, and Federal Economic Trends <br />^ Future Local Growth Trends <br />^ Major Public and Private Improvement Projects - <br />Rail and Airport Improvements <br />School Buildings <br />Governmental Buildings <br />^ Major Commercial Buildings <br />One method of determining the I'rfe of an operation is to evaluate the past demand for gravel resources. By <br />using the last three years of production, in conjunction with the remaining resource, it is forecasted that the <br />gravel within the e~anded area will be depleted in about 25 years. It should be pointed out that forecasts are <br />based on current and past information. Inherent with any forecast is a degree of uncertainty. A 25 year life <br />span is a relatively short period of time for a sand and gravel operation such as ebsts at the Gypsum Ranch PiL <br />USE , AREA <br />IN AC. <br />OF TOTAL <br />Epsting Permd 120.9 77.8 <br />Pro sed Addition 34.6 ! 22.2 <br />TOTAL 155.6 i <br />Gravel Extraction 92.6: 59.5 <br />Sta in Area 36.6 23.5 <br />No Disturbance and Buffer Areas 26.4 17.0 <br />Rev. 08/10/03 <br />
