Grading will occur as site preparation for building <br />and road construction. An average of ten (10) inches of topsoil <br />materials will be salvaged prior to disturbance, and stockpiled for <br />reclamation. <br />2.04.10 Vegetation Information <br />Kent Crofts of IME Consulting performed an initial vegetation survey of <br />the proposed disturbed area in February, 2007with site sampling <br />during the summer of 2007. The full report is provided in Exhibit J. <br />Two vegetation communities were identified: Juniper-Grassland and <br />Disturbed Grassland. Sample adequacy was achieved at the 90% <br />confidence interval for plant cover, herbaceous production and woody <br />plant densiity for the Juniper-Grassland Predisturbance Area and <br />corresponding Juniper-Grassland Reference Area. Sample adequacy <br />was also achieved for plant cover and herbaceous production on the <br />Disturbed F~redisturbance Area. Sample adequacy was achieved for <br />plant cover on the Disturbed Reference Area. <br />Statistical analysis of data indicated that the selected reference areas <br />were statisitically similar to the pre-disturbance areas and therefore, <br />would be appropriate as areas for measurement of final revegetation <br />success. <br />2.04-29 Revised 11/05/07 <br />
