Clustering of units is encouraged. Gross acreage includes the property at issue plus a share of adjacent roads and any adjacent,permanently dedicated,open lends. 2 Usage intensity calculations shall include all people(e.g.,employees,customers/visitors,etc.)who may be on the property at a single point in time, whether indoors or outside. Multiplier bonus for Special Risk-Reduction Bldg.Design is 1.5 for Zone 2 and 2.0 for Zones 3,4,5,and 7. (Appropriate risk reduction measures are specified in the California Code of Regulations,Title 24,Part 2.) 3 Open land requirements are intended to be applied with respect to an entire zone. This is typically accomplished as part of a com- munity general plan or a specific plan,but may also apply to large(10 acres or more)development projects. 4 The uses listed here are ones that are explicitly prohibited regardless of whether they meet the intensity criteria. In addition to these explicitly prohibited uses,other uses will normally not be permitted in the respective compatibility zones because they do not meet the usage intensity criteria. 5 As part of certain real estate transactions involving residential property within any compatibility zone(that is,anywhere within an airport influence area),information regarding airport proximity and the existence of aircraft overflights most be disclosed. This re- quirement is set by state law. Easement dedication and deed notice requirements indicated for specific compatibility zones apply on- ly to new development and to reuse if discretionary approval is required. 6 Hazards to flight include physical(e.g.,tall objects),visual,and electronic forms of interference with the safety of aircraft operations. Land use development that may cause the attraction of birds to increase is also prohibited. 7 Examples of highly noise-sensitive outdoor nonresidential uses that should be prohibited include amphitheaters and drive-in thea. ters. Caution should be exercised with respect to uses such as poultry farms and nature preserves. 8.

However,the Federal Aviation Administration may require marking and lighting of certain objects. 10 This height criterion is for general guidance. Shorter objects normally will not be airspace obstructions unless situated at a ground elevation well above that of the airport.Taller objects may be acceptable if determined not be obstructions. 11 Natural gas&petroleum pipelines less than 36 inches below the surface.
