3.10.7 ~: The 10-story building may interfere with aircraft executing a base leg approach to Runway 12 over the Project site. F~10.iil~: The City hereby makes finding (1). Facts in Support of Findings: (a) Exhibit 25 of the Airport Study depicts arrival profiles for Runway 12 from the pattem altitude of 800 feet MSL directly over the location of the 1 O-story abeam the runway), (2) a left base approach at 60 knots; and (3) a left base approach at 100 knots. From this Exhibit, it can be determined that an aircraft in the traffic pattern or on a base leg approach to Runway 12 overflying the 10-story office building would be at altitudes ranging from about 304 to 497 feet MSL, or from 157 to 352 feet over the top of the building. (b) Exhibit 25 also shows the relationship of the existing Paragon building to such approaches. As can be seen from the exhibit, aircraft currently fly much closer tO the top of the Paragon building (from 131 to 276 feet) than they would to the Project (from 153 to 346 feet). 3.10.8 ~: The 151 foot high building could have a deleterious effect on the operation of an air navigation facility (the San Carlos Tower) in that it could severely restrict the minimum altitude for aircraft descending on a short base to final approach to Runway 12 over the proposed building. F~a.~JJlg~: The City hereby makes finding (1). Facts in Support of Findings: (a) Aircraft executing a base to final approach to Runway 12 from the vicinity of the KNBR tower would be at altitudes of approximately 300 to 360 feet MSL as they pass over the site of the 10-story building. Therefore, the minimum clearance over the top of the building would be approximately 150 feet. (b) Aircraft on such an approach to Runway 12 would fly much closer to the top of the existing Paragon building (approximately 130 feet). Moreover, if 150 feet clearance were required over the top of any building in the San Carlos Class D airspace, the 222-foot high Oracle building would be the controlling object. (c) At least three existing buildings in the immediate vicinity of the Project would require that altitudes in excess of 300 feet MSL be maintained if a descending aircraft is to maintain 150 feet of clearance over these buildings on approach to Runway 12. To clear the DHL building by 150 feet, an aircraft would have to be at an altitude of about 316 feet MSL as it passed by the Project site. To -25- EAFNDGCCDOC 7/11/96 9:56 AM
