AIRPORT MASTER PLAN runway with a C-III RDC. As a result, some significant improvements would be required to accommodate RSA standards if Runway 17/35 or Runway 8/26 move into the C-III RDC category. Figure 4-1 and 4-2 identify the impacts of expanding the Runway RSA and ROFA dimensions (i.e. ROFA dimension impacts are discussed in the next section) for Runway 8/26. As Figure 4-1 shows, the RSA and ROFA associated with the approach end of Runway 8 would extend over the existing location of Airport Drive. Consequently, Airport Drive would need to be relocated outside the RSA and ROFA or the threshold of Runway 8 would need to be relocated approximately 300 feet to the east if the runway was moved to a C-III RDC. Additionally, it should be noted that the ROFA for Runway 8/26 will extend into the ramp area for the Taxiway Kilo Development Area. Since the ROFA clearing standard precludes parked aircraft, a small portion of the ramp will not be usable for aircraft parking. Figure 4-2 shows that a similar issue exists at the approach end of Runway 26 where the airport perimeter road passes through the C-III RSA and ROFA. In this case, the roadway would need to be closed or relocated outside of the RSA/ROFA or the threshold of Runway 26 would need to be relocated approximately 295 feet to the west. If the roadway is not close or relocated, it would be necessary to protect the RSA and ROFA informational signs directing vehicle desiring to cross through the RSA/ROFA to contact ATCT for permission. These issues would make it difficult to move Runway 8/26 to C-III standards without making significant infrastructure modifications. Facility Requirements Chapter Page 16 of 70 October 2020
