3.10.15 ~: Construction of the Project could expose people to frequent <br /> and/or high levels of aircral~ noise. <br /> <br /> aY. Jil.0J.!~: The City hereby makes finding (1). <br /> <br /> Facts in Support of Findings: <br /> <br /> (a) Airport noise concerns are normally directed at residential land uses. <br /> Office and commemial uses are generally deemed compatible with all but the <br /> <br /> '(b) The Project is locmed within the CNEL 55-60 dB noise comour for the <br /> Airport. Business and professional uses are considered compatible with noise <br /> levels up to CNEL ?0 dB. <br /> <br /> (c) The 1 O-story building will not reflect or otherwise increase alrcraf~ noise <br /> in residential areas. <br /> <br />3.10.16 P3~ltaliaLKlI~: When operating in the Airport traffic pattern, pilots seeking to <br /> .avoid Project office buildings might tend to operate their aircraft further to the <br /> east. Pilots also might choose, for safety reasons, to avoid the project area by <br /> flying farther out. Both of these circumstances might create an increase in noise <br /> over residential areas in Redwood Shores. This would affect citizens in the <br /> Belmont Channel area and along Bridge Parkway. <br /> <br /> F_Jatlil~: The City hereby makes finding (1). <br /> <br /> Facts in Support of Findings: <br /> <br /> (a) The analyses conducted in order to evaluate safety issues concluded that <br /> the 10-story building is not an obstruction to air navigation. Therefore, aircraft <br /> will not have to avoid it by flying around the building and over existing <br /> residential areas. As a result, noise levels from aircraft will not increase in these <br /> residential areas. <br /> <br /> (b) The location of the 10-story office building would not require aircraft in <br /> the traffic pattern to fly their downwind leg further east, thereby moving noise <br /> further into Redwood Shores residential areas. The location of the building is <br /> about 1~500 feet offthe extended runway centerline. The downwind leg of the <br /> traffic pattern is typically flown from 1,000 to 3,000 feet abeam the runway. This <br /> would place the building within the inner portion of the traffic pattern. The outer <br /> portion of the pattern would be over the noise sensitive area of Redwood Shores. <br /> The pattern altitude in either case is 800 feet MSL, and the building location <br /> would have no effect. <br /> <br /> -32- <br /> EAFNDGCC.DOC <br /> 7/I 1/96 9:56 AM <br /> <br /> <br />
