Schulte City of Carlsbad Planning Dept. 2075 Las Palmas Avenue Carlsbad, CA 92009-4859 Subject: Sudan Interior Mission Development Proposal Dear Lance: SANDAG staff has reviewed the proposed development by the Sudan Interior Mission. These comments have not been reviewed by the SANDAG Board of Directors acting as the Airport Land Use Commission. Attached is a copy of the adopted airport noise/land use compatibility matrix. Residential development between the 60 and 65 CNEL contour should meet two conditions which are described on the back of the matrix. Those conditions are noise attenuation and an avigation easement. Thank you for allowing us an opportunity to participate in the city’s review process. If you have any questions, pleae call Ruth Potter or myself. Sincerely, JA~K KOERPER Special Projects Director JK/dab MEMBER AGENCIES: Cities of Carlsbad, Chula Vista, Coronado, Del Mar, El Cajon, Encinitas, Escondido, Imperial Beach, La Mesa, Lemon Grove, National City, Oceanside, Poway, San Diego, San Marcos, Santee, Solana Beach, Vista and County of San Diego.

AATRiX COMPATIBLE The outdoor day night average sound level Is sufficiently attenuated by conventional construction that the indoor noise level is acceptable, and both indoor and outdoor acthfitles associated with the land use may be carried out with essentiaily no inter- ference from aircraft noise. CONDITIONALLY COMPATIBLE The outdoor day night average sound level will be aitenuated to the Indoor level shown, and the outdoor noise level Is acceptable for arsoclated outdoor activities. U INCOMPATIBLE The day night average sound level Is severe. Although extensive mitigation techniques could make the indoor environment acceptable lor performance of activities the outdoor environment would be Intolerable for outdoor activities assoclated with the land use. This matrix should be used with reference to the Implementation Directives shown on the reverse. AIRPORT NOISE/LAND USE COMPATIBILITY MATRIX IMPLEMENTATION DIRECTIVES All the uses specified are "compatible" up to the noise level indicated. Specified uses are also allowed as "conditionally compatible" in the noise levels shown if two specific conditions are met and certified by the local general purpose agency: o Proposed buildings will be noise attenuated to the level shown on the matrix based on an acoustical study submitted along with building plans. o In the case of discretionary actions, such as approval of subdivisions, zoning changes, or conditional use permits, an avigation easement for noise shall be required to be recorded with the County Recorder as a condition of approval of the project. A copy shall also be filed with the affected airport operator. For all property transactions, appropriate legal notice shall be given to all purchasers, lessees and renters of property in "conditionally compatible" areas which clearly describes the potential for impacts from airplane noise associated with airport operations. Notice also will be provided as required on the state Real Estate Disclosure form. Identified uses proposed in noisier areas than the level indicated on the matrix are considered "incompatible .I' The directives below relate to the specific "conditionally compatible" land use categories identified by number on the matrix. 3. 4. 5. 6. a. New schools, preschools and libraries located within the 60-65 dB DNL contours must be subjected to an acoustical study to assure that interior levels will not exceed 45 dB DNL. New residential and related uses located within the 60-65 dB DNL contours must be subjected to an acoustical study to assure that interior levels will not exceed 45 dB DNL. Appropriate legal notice shall be provided to purchasers, lessees, and renters of properties in this conditionally compatible zone in the manner previously described. "Residential hotels" are defined as those that have 75% or more of accommodations occupied by permanent guests (staying more than 30 days) or those hotels which have at least 5 0 percent of their acco m modat ions containing kitchens. Transient Lodging is defined as hotels and motels, membership lodgings (Y's, etc.), suite or apartment hotels, hostels, or other temporary residence units, not defined as residen- tial hotels, above. Within the 60-70 dB DNL contours, buildings must be subjected to an acoustical study to assure that interior levels do not exceed 45 dR DNT,. Appropriate legal notice shall be provided to purchasers, lessees, and renters of properties in this conditionally compatible zone in the manner previously described. Office buildings include many types of office and service uses: business and business services; finance, insurance, real estate; personal services; professional (medical, legal and educational); and government, research and development and others. Within the 65- 70 dB DNL contours, buildings must be subjected to an acoustical study to assure that interior levels do not exceed 50 dB DNL. Appropriate legal notice shall be provided to purchasers, lessees, and renters of properties in this conditionally compatible zone in the manner previously described. For new commercial retail uses located within the 65-75 dB DNL contours, buildings must be subjected to an acoustical study to assure that interior levels do not exceed 50 dB DNL. Appropriate legal notice shall be provided to purchasers, lessees, and renters of properties in this conditionally compatible zone in the manner previously described.
