Description: The dataset represents the six public use airport referral areas of the Comprehensive Airport Land Use Plan for Sonoma County (CALUP). The CALUP Chapter Eight established these geographic boundaries for referral of projects to the Sonoma County Airport Land Use Commission. Within each referral area, noise compatibility standards, safety compatibility standards, airspace protection standards, and other land use policies are to be applied comprehensively. Where any parcels of land are subject to more than one set of land use compatibility standards or policies, the most restrictive standard shall apply. In establishing the referral area boundaries, a distinction can be made between the referral area of each of the six public-use airports in the County; defined as the area within which noise, airspace, or safety factors may affect land use compatibility - and the more limited area within which a close look at compatibility is essential. The latter is the primary referral area while the remaining portions of the airport influence area are treated as a secondary referral area. The limits of the airport referral areas are set by the various compatibility zones described in Chapter 8. Except at the Sonoma County Airport, the airport referral area is bounded by the outer edge of the F.A.R. Part 77 conical surface. At Sonoma County Airport, the F.A.R. Part 77 approach surface for Runway 32 extends the boundary to the southeast. In addition, the 55 CNEL contour extends the boundary a short distance beyond the conical surface to the northwest off the end of Runway 14-32. The secondary referral areas for each airport lie within the larger primary referral area. They include areas exposed to noise above 55 CNEL and beneath commonly used flight tracks and traffic patterns. These areas are discussed in greater detail below. In the secondary referral area, airport compatibility problems will seldom arise. The principal concern within the secondary referral area is the proposed construction of any structure to a height substantially in excess of that permitted under the land use zoning for that area. Exhibits C1 through C6 (refer below for online access to exhibits) show the referral area boundaries for each airport. As already noted, they encompass areas which are either beneath or near to the typical aircraft flight tracks or are projected to be affected by future noise levels of 55 CNEL or greater. Wherever possible, the boundaries follow roads or other easily identifiable geographic features. In some instances, parcel lines are used. A brief discussion of the factors considered in drawing each set of referral area boundaries can be reviewed online at CALUP, 8.2.1.a through f (http://www.sonoma-county.org/prmd/docs/airport/ch8-excerpt.htm). To note, the descriptions of each airport's physical features, its use, and its environs are found in Chapters Two through Seven of the CALUP for Sonoma County.
