:;..ry¡:: 3.0 FY 1993 AIRPORT IMPROVEMENT PROJECTS The FY 1993 Allport Improvement Projects will include a continuation of the apron rehabilitation program (approximately 15 acres), rehabilitation and reconstruction of the airport access road from the terminal building to the last end of the apron, and clearing of obstructions from the R/W 12-30 drainage outfall channel that may have contributed to a back-up of stonn water causing the water to sit on the airfield and percolate up through the pavement. Detailed engineering cost estimates of the proposed improvements are included in the following pages. 4.0 FY 1994 AIRPORT IMPROVEMENTS PROJECTS It is anticipated that the FY 1994 Airport Improvement Projects will include a continuation of the apron rehabilitation program (approximately 15 to 30 acres), installation of MITL on all taxiways leading to lighted runways, and installation of the emergency back-up electrical generator. 5.0 FUNDING CONSIDERATION The funding sequence for these airport improvement projects is predicted on the ability of the City of San Marcos to fund the local, sponsor's share on an annual basis. To date, it appears that an annual total project cost of approximately $1,000,000 is attainable which has caused the entire program of improvements to be extendêd over a three to four year period as FAA funding is available. Perhaps, most importantly, the October 1990 preapplication appears to have been based on several assumptions which were later found to be either not applicable or invalid. Primary among those was the ability to simply overlay the existing concrete. As was determined during the pavement evaluation process, this type of improvement would have created severe maintenance and repair costs in the future due to the deterioration of much of the concrete pavement and the lack of strength gained from a two inch overlay. These types of project assumptions caused the October 1990 preapplication projects to be considerably underestimated; possibly by as much as fifty percent. In addition, highway and airport construction costs are in an increasing mode due to the relatively high quantities of work available. All of these factors have combined to potentially increase the total project cost of all of the improvements. .
