3.10.5 Y~/.t_elllhlll, lle~: Aircraf~ approaching the airport from the vicinity of the KNBR tower would not be able to see aircraft climbing out after departure on Runway 30 behind the Project buildings, especially the 10-story office building. Eillllil~: The City hereby makes finding (1). Facts in Support of Findings: (a) Exhibit 24 of the Airport Study shows the line-of-sight from the vicinity of t.h_~ _I(_-NI~'.~II~. t. OW~r _t>V~' ~ 1_ 0-Sl~kry huilrlln~o tD t~ C~'-t~nrlocl eonterlj.la~ nn Rll~way 30. The exh~it shows that amving aircraft in the vicinity of the KNBR tower would have to be below 700 feet MSL for the 10-story building to block the line of sight from the aircraft to the extended runway centerline. Aircraft in this area typically are at an altitude of about 1,200 MSL. Similarly, aircraR in the traffic pattern would also have an unobstructed view of the airport and extended runway centerline. (b) The existing Paragon building, because of its position nearer the extended runway center line, already impedes the line of sight from the KNBR tower in this area. The Project would not impair this line of sight. 3.10.6 P_olrdl.fial.F,~[e~: Project buildings may interfere with the Belmont Slough Departure from Runway 30, as well as with arrivals in the local trafficpattem. F_iB_0iII~: The City hereby makes finding (1). Facts in Support of Findings: (a) The base leg or crosswind turns would most likely occur anywhere from 7,200 to 10,000 feet from the ATCT (or from 5,600 to 8,400 feet from the nearest runway end). At a distance of 7,200 feet from the tower, controllers would not be able to see any objects below 200 feet MSL behind the 10-story building. At a distance of 10,000 feet from the control tower, only objects behind the lO-story office building below 265 feet MSL would not be visible to controllers. This would not represent a problem, as aircraft in these areas operate well above these altitudes. -24- 7/11/96 9:56 AM
