3.10.7 Potential Effect: The 10 -story building may interfere with aircraft executing a <br />base leg approach to Runway 12 over the Project site. <br />F ndin s T City hereby makes finding (1). <br />Facts in Suonort of Findings: <br />(a) Exhibit 25 of the Airport Study depicts arrival profiles for Runway 12 <br />from the pattern altitude of 800 f MSL directly o ver the location of the <br />10 -story building for thred scenarios: (1) a close -in. pattern (approximately 2,300 <br />feet abeam the runway), (2) a left base approach at 60 knots; and - :( 3 ) a left base <br />ap proach at 100 dots.. From this Exhibit, it can be determined that an aircraft in <br />the traffic pattern or on a base leg approach to Runway 12 overflying the 10 -story <br />office buildin g would be at altitudes ranging f corn about X04 to 497 feet .MSL, or <br />from 157 tv 3 52 . feet over the top o f the -building. <br />(b) Exhibit .25 also shows the relationship of the existing Paragon building to <br />such approaches. As can be seen from the exhibit, aircraft currently fly much <br />closer to the to p g of the Parag building (from 131 to .276 .feet) than they would <br />to the Project (from 153 to .346 feet). <br />3.10.8 Potential Effect: The 151 foot high building could have a deleterious effect on <br />.the operation of an air navi g ation facility (the San Carlos Tower) in that it could <br />severely restrict the <br />Minimum altitude for aircraft descending on a short .base to <br />final approach to Runway 12 over the proposed building. <br />Findin s; The pity hereby makes finding (1). <br />Facts in Su ort of Findn s: <br />(a) Aircraft executing a base to final approach to Runway 12 from the vicinity <br />of the KNBR tower would be at altitudes of approximately 300 to 360 feet MSL <br />as they y pass over the site of the 10- story building. Therefore, the <br />clearance over the top of the building would be approximately 15 0 . feet. <br />(b) Aircraft on such an approach to .Runway 12 would fly .much closer to the <br />to of the existin. .P on buildin (app 130 feet). Moreover 150 <br />P g � g <br />feet clearance were rewired over the top of any building in the San Carlos Mass <br />� hi <br />airspace, the 222 -foot h Oracle building would be the controlling object. <br />p � <br />(c) At least three existing buildings in the inimediate vicinity of the Project <br />would <br />require that altitudes <br />in excess of 300 feet MSL be maintained if a <br />descendin g aircraft is to maintain 150 feet of clearance over these buildings on <br />FNDNGPI .DOC <br />513419610:51 AM <br />
