Excavation will require <br />simple blading techniques. Excavated material <br />can be spread thinly over interior arecs not to <br />be graded or areas designated for agricultural <br />purposes as shown in Figure 1. If an indepen- <br />dent contractor is required to do the work, a <br />field survey with cross-sections would be <br />necessary to compute the amounts of earth to <br />be moved for bidding purposes. <br /> <br />Graded areas will require seeding, watering, <br />and fertilizing, if necessary, to minimize <br />erosion. <br /> <br />It should be noted that care must be taken <br />during grading operations adjacent to Runway <br />12-30 and Taxiway C to protect existing medium <br />intensity runway lights. Although the light <br />fixtures are stake-mounted and can be easily <br />moved, buried cable must be located and protected. <br /> <br />3. It appears that a small drainage structure is <br />needed to relieve storm water collecting north <br />and east of the airport entrance road. This <br />could be accomplished by the placement of an <br />18-Inch pipe culvert under the entrance road. <br />A field survey will be required, however, to <br />determine the most efficient location of such <br />a structure in terms of outfall effects and <br />capacity. <br /> <br />A-4 <br />
