AIRPORT MASTER PLAN <br />related to the currentRDC for each runway. Each of these aspects of runway design <br />are discussed in more depth in the subsections below. <br />Additionally, since the Forecast chapter identified the potential for the critical <br />aircraft to move into the C-III category, an analysis was completed to determine the <br />impacts of each of the three runways moving into the C-III category and the ability <br />for each runway to meet C-III design standards. Table 4-11, Future Runway Design, <br />identifies the potential limitations/constraints of shifting the critical aircraft for each <br />runway into the C-III category. <br /> <br />TABLE 4-11 <br />FUTURE RUNWAY DESIGN <br />SAN MARCOS REGIONAL AIRPORT <br />FAA Design Runway Runway Runway <br />Item <br />Standard (C-III)13/3117/358/26 <br />Runway Design: <br />Width (ft)150100100100 <br />RSA Width (ft)500500150150 <br />RSA Length beyond R/W end (ft)10001000300300 <br />OFA Width (ft)800800500500 <br />OFA Length beyond R/W end (ft)10001000300300 <br />ROFZ Width (ft)400400400400 <br />ROFZ Length beyond R/W end (ft)200200200200 <br />Runway Setbacks -Runway Centerline to: <br />Parallel Taxiway Centerline (ft)400630N/A630 <br />Holdline (ft)250250 - 290200250 - 290 <br />Aircraft Parking Area (ft)500705N/A710 <br /> <br />Source: FAA AC 150/5300-13. <br />The areas where the existing infrastructure or a protected surface would have to be <br />modified are shown in red text. The cells highlighted in yellow notate items where a <br />potential limiting factor exists that could hamper a move to C-III standards. Each of <br />these areas are discussed in more detail in the subsections below. An analysis of <br />the Runway Protection Zones (RPZs) is also provided later in this chapter. <br />Runway Width <br />FAA AC 150/5300-13 (current series) delineates the requirements for runway width. <br />At present, all runways at the San Marcos Regional Airport are 100 feet wide. This <br />width meets the minimum runway width recommended in AC 150/5300-13 for <br />runways with a C-II RDC (Runway 13/31) and exceeds the B-II RDC standard <br />(Runway 8/26 and Runway 17/35) of 75 feet. <br />Facility Requirements Chapter Page 14 of 70 <br />October 2020 <br /> <br />
