The City Plarmer has determined the project is exempt from the Califomia Environmental 22 Quality Act (CEQA) because it will not have a significant effect on the environment. This determination is pursuant to State CEQA Guidelines Section 15061(b) (3), which states "when it can be seen with certainty that there is no possibility that the 24 activity in question may have a significant effect on the environment, the activity is not subject to CEQA." 25 " 26 27 28 PC RESO NO. 6855 -2- 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 PASSED, APPROVED, AND ADOPTED at a regular meeting of the Planning Commission of the City of Carlsbad, Califomia, held on January 4, 2012, by the following vote, to wit: AYES: NOES: Chairperson Schumacher, Commissioner Black, L'Heureux, Nygaard, Scully and Siekmann ABSENT: Commissioner Amold ABSTAIN: MICHAEL SCHUMACHER, Chairperson CARLSBAD PLANNING COMMISSION ATTEST: DON NEU City Planner PC RESO NO. 6855 -3- Underline/Strikeout Exhibit Section II.C.5 Exhibit X'1 Land Use Element the area commonly referred to as the "downtown." Permitted land uses may include retail stores, offices, financial institutions, restaurants and tourist-serving facilities. Residential uses can be intermixed throughout the area. The Village Area is regulated by the Carlsbad Village Master Plan. f. Office and Related Commercial (O): This classification designates areas that are compatible with and environmentally suited for office and professional uses, as well as related commercial uses. This designation is especially appropriate for medical office use. Office and related commercial land use can be used as buffers between retail commercial areas and residential uses. 4. PLANNED INDUSTRIAL (PI) Planned Industrial land uses include those areas currently used for, proposed as, or adjacent to industrial development, including manufacturing, warehousing, storage, research and development, and utility use. Agricultural and outdoor recreation uses on lots of one acre or more are considered to be a proper interim use for industrially designated areas, 5. GOVERNMENTAL FACILITIES (G) This classification of land use designates areas currently being used for major governmental facilities by agencies such as the city, county, state, or federal government. Facilities within this category may include uses such as civic buildings, libraries, maintenance yards, police and fire stations and airports (McClellan- Palomar Airport). Smaller facilities, such as branch libraries, may be found in other land use designations, such as commercial, and are not shown on the land use map. The largest facility within this classification is the McClellan-Palomar Airport located at the center of the City. The airport, owned and operated by San Dlego County, serves as a major-general aV^ationis classified by the Federal Aviation Administration as a commercial .service airport and provides general aviation, business jets and limited commuter San ailiins_.seryices_.to -faotlity-fof Diego County. More detailed northern discussions related to the airport may be found under Special Planning Considerations, as well as in the Noise, Circulation, and Public Safety Elements. 6. PUBLIC UTILITIES (U) This category of land use designates areas, both existing and proposed, either being used or which may be considered for use for public or quasi-public functions. Primary functions Include such things as the generation of electrical energy, treatment of waste water, public agency maintenance storage and operating facilities, or other primary utility functions designed to serve all or a substantial portion of the community. Sites identified with a "U" designation indicate that the City is studying or may in the future evaluate the location of a utility facility which could be located within a one kilometer radius ofthe designations on a site for such a facility. Specific siting for such facilities shall be accomplished only by a change of zone, and an approved Precise Development Plan adopted by ordinance and approved only after fully noticed public hearings. 7. SCHOOLS This land use classi^cation represents both existing and proposed school sites necessary to serve the ultimate planning area. Sites are designated as elementary, junior high, high school, continuation school, and private school facilities. For additional discussion see Special Planning Considerations A. Schools. 8. OPEN SPACE & COMMUNITY PARKS (OS) The Land Use Map shows the generalized boundaries of constrained lands and presently designated open space, including existing parks and special resource areas. It is not intended that the map show all future open space. The Open Space and Conservation Element ofthe Underiine/Stnlieout Exhibit Section II.D.4 Exhibit X-1 Land Use Element 2. VILLAGE The Village is the segment of the community located in the "downtown" Carlsbad. The Carlsbad Village Master Plan provides an overall development strategy to create a strong identity for the Village, revitalize the area, enhance the economic potential of the Village and establish specific site development standards. The intent of the Carlsbad Village Master Plan is to preserve the village character of the area by creating a pedestrian scale environment of specialty shops, services, and restaurants complemented by residential and mixed-use development. Carlsbad Village Master Plan should be referred to for more detailed information. 3. COASTAL ZONE PROGRAMS In 1972, California voters approved Proposition 20 which led to the enactment of the State law (California Coastal Act of 1976) which regulates any development within California's Coastal Zone. The Coastal Act requires that individual jurisdictions adopt Local Coastal Programs (LCP) to implement the State law at a local level. Carlsbad's Local Coastal Program is consistent with the General Plan, but it Is a separate document containing separate land use policies and implementation measures which must also be complied with in addition to the General Plan. Approximately one-third of the City is located within the Coastal Zone. The City's coastal zone has been divided into six segments and each segment is regulated by separate LCPs (See Map 4: Local Coastal Program Boundary). The boundaries of the City's Coastal Zone which were established by the State are depicted on the Land Use Map, Almost every conceivable type of development proposal within the Coastal Zone from removal of natural vegetation to the construction of huge master planned communities, requires the approval of a Coastal Development Permit (CDP) in addition to any other permits or entitlements. The land use policies, programs and regulations of the relevant LCP shall be referred to in addition to the General Plan, the Municipal Code and other pertinent regulations for guiding land use and development within the Coastal Zone. Although the City has adopted LCP segments for all of its Coastal Zone, It only has authority to issue Coastal Development Permits within the Redevelopment segment. In the remaining five segments the Califomia Coastal Commission currently retains Coastal Development Permit authority. Carlsbad is actively pursuing the lengthy task of effectively implementing the five LCP segments in order to transfer permtt authority to the City. In those circumstances where an issue is not addressed by the Local Coastal Program Land Use Plan, but is addressed by the City of Carlsbad General Plan, no coastal development permit, or exemption may be granted unless the project considered is found by the appropriate authority to be consistent with the City of Carlsbad General Plan, In those circumstances where an issue is addressed by both the Local Coastal Program Land Use Plan and the City of Carlsbad General Plan, the tenns of the Local Coastal Program Land Use Plan shall prevail. 4. McCLELLAN-PALOMAR AIRPORT Caiifornia , jaw requires preparation of airport land use compatibility plans for each public-use and military airport in the state. The basic functipri of such plans is to promote compatibility between airports and the land uses that surround them For McClellan-Palomar Airport, a Gsuftty-GW/ned -faGiirty. 4s-fe9u(stecl by the San Dieqo County Afrport Land Use Commission Goin^vehensive • Land Um Plan. • McClell^n- Paiomaf-{Gi=lJP-}- -prepared—by- -the-Safr- As&oe4ation--of—GovernmeBts (SAMQAGlhas prepared , and adopted the McCleljan-Paiomar Airport Land Use Comoatibihtv Plan (ALUCP).

If the City chooses to overrule a finding of the Airport Land Use Commission as stated in the CLUPAUUCP, it may do so by a two-thirds vote if it makes a specific findings that the General Plan and the CLUP are is consistent with the intent of „state airport land use planning statutes. To limit noise impacts on noise sensitive land uses, the City has designated areas surrounding the Airport for predominately planned industrial uses. To accomplish this, a significant amount of nonresidential land has been designated on the plan, possibly exceeding what is needed to serve and accommodate future residential uses located exclusively in Carlsbad. As such, future re-designation of planned residential areas to non-residential uses to accommodate future airport growth would not be supported. (Also see UA designations.) 5. AGRICULTURE Agriculture is an important resource in Carlsbad. The City's agricultural policies are intended to support agricultural activities while planning for the possible future transition of the land to more urban uses consistent with the policies of the General Plan and the Carlsbad Local Coastal Program (LCP). The City's LCP protects agricultural lands from the premature conversion to more urban land uses by establishing programs which require mitigation for conversion of agricultural property to urban uses. It also has established methods to benefit agriculture in the community by providing financial assistance through cash programs. While the City encourages agriculture, it recog- nizes the potential problems associated with ag- ricultural land use. For example, to prevent the destruction of sensitive wild and archaeological resources, clearing and grubbing of natural areas for agriculture requires a permit and environmental review. Also, the City encourages conservation techniques in agricultural activities to reduce soil erosion and water usage, 6. REGIONAL ISSUES As a member of the San Diego Association of Governments (SANDAG), the City is participating with other cities in the county to develop a Regional Growth Management Strategy. This effort recognizes the fact, that as separate entities, each city cannot solve region- wide issues. Together, however, a strategy can be developed to establish a framework for a "regional community" \Anth an improved quality of life. Carlsbad recognizes its role as a participant in this effort which focuses on the following nine Important environmental and economic factors: a. Air Quality b. Transportation System and Demand Management c. Water d. Sewage Treatment e. Sensitive Lands Preservation and Open Space Protection f. Solid Waste Management g. Hazardous Waste Management h. Housing i. Economic Prosperity. 7. AREAS NEEDING ADDITIONAL PLANNING For a variety of reasons, there are areas within the City that have unresolved land use considerations which should be addressed prior to the occurrence of a significant amount of further development. The City has planned for these areas on a General Plan level but due to their unique characteristics they will require a more specific level of planning review to ensure that such characteristics are addressed comprehensively. More specific levels of review may include such mechanisms as specific plans, site development plans, special studies, or overlay zones. Locations that have been identified as having unresolved planning considerations are discussed bhefly below for detemiination at a future time. Other areas may be identified in the future as also requiring additional review. Undeiiine/Striifeout Exhibit Section III.

Underline/Strikeout Exhibit Section I.O Exhibit X-2 ciRCiLiT/0:\i:iJ:Mt::\T Safety Elements. All these elements address vahous aspects of the circulation system and together they provide the basic policies and guidelines for the development of a safe, efficient and aesthetically pleasing transportation network. These elements should be referred to for more detailed discussion. For example, the public facilities discussed in the Circulation Element are also discussed in the Land Use Element. It is the policy of the City of Carlsbad that the Circulation Element be consistent with all other elements of the General Plan. manner within a climate of increasingly strict environmental guidelines. The City must also find ways to refine the existing circulation network in the developed portions of the City to accommodate increased redevelopment activity and the development of surrounding communi- ties. Finally, it is recognized that the City circulation system is a part of the larger regional, state, and national transportation systems. As such, the City circulation system will continue to be influenced by the demands placed upon it by larger transportation system needs. D. THE CITY OF CARLSBAD SETTING E. CAPITAL IMPROVEMENT PROGRAM The dominant natural and manmade features In Carlsbad, which establish the framework within which the circulation network must function, include the Pacific Ocean to the west, the three natural lagoons extending from the ocean to the interior of the City, the steep hills and canyons which punctuate the eastern half of the community^ Highway 78 along the northern boundary, the Coast Highway, the AT&SF railroad and Interstate 5. These features all serve to separate the coastal portion of the City from the interior portion. There are three major, existing, arterial roads in the City, including, El Camino Real which runs north and south through the center of the City, Palomar Airport Road which runs east and west through the center of the City, and Rancho Santa Fe Road which runs along the southern and easteriy boundary of the City, In addition, Carlsbad has a gefteFal--avtatKjft oommirteFGommerclal service airport located in the central portion of the City adjacent to the intersection of Palomar Airport Road and El Camino Real. Goals, objectives, and policies and programs related to air transportation are included in this element, but are also discussed in the Land Use Element. Given the existing topographic constraints, the City has developed an integrated land use and circulation plan to take advantage ofthe natural landform features and the existing transportation facilities. A major challenge for the City in the future will be to complete the remaining roadway segments of the Circulation Element in a timely The construction of unbuilt circulation element roads and public utilities will be brought about through a combination of construction activities undertaken by the development community and the City of Carlsbad. The guiding theme for the construction of the circulation element infrastruc- ture is the provision of facilities prior to or concurrent with the need for such facilities. To this end the City has established the Grovrth Management Program, the Capital Improvement Program and a development exaction program consisting of public facility impact fees and direct developer construction of putilic road, public trail and utility improvements. The Grovrth Management Program establishes minimum standards for the provision of basic public infrastructure including circulation element roads, sewer collection, sewer treatment, water distribution and flood control. In addition, the Growth Management Program requires the preparation of Local Facilities Management Plans to ensure that the public facility standards are met through buildout for each of the 25 local facility zones.

BACKGROUND AND INTENT The goal of the Noise Element is to achieve and maintain an environment which is free from objectionable, excessive or harmful noise. The Noise Element Identifies and defines existing and future environmental noise levels from sources of noise within or adjacent to the City of Carlsbad by means of Noise Contour maps. Establishes goals, objectives and policies to mitigate these noise impacts. Provides policies and action programs to implement the Goals and Objectives. "The Goal of the Noise Element is to achieve and maintain an environment which is free from objectionable, excessive or harmful noise." B. STATE LAW Section 65302(f) of California's Planning and Zoning Laws requires a Noise Element which identifies and appraises noise problems in the community. The Noise Element shall recognize the guidelines established by the Office of Noise Control in the State Department of Health Services and shall analyze and quantify, to the extent practicable, as determined by the legislative body, current and projected noise levels for all of the following sources: 1. 2. 3, 4. Highways and freeways; Primary arterial and major local streets; Passenger and freight online railroad operations and ground rapid transit systems; Commercial, general aviation, heliport, helistop, and military airport operations, aircraft overflights, jet engine test stands, and all other ground facilities and maintenance functions related to airport operation; 5. Local industrial plants, including, but not limited to, railroad classification yards; and 6. Other ground stationary noise sources identified by local agencies as contributing to the community noise environment. Noise contours shall be shown for all of these sources and stated in terms of community noise equivalent level (CNEL) or day-night average level (Ldn). The noise contours shall be prepared on the basis of noise monitoring or following generally accepted noise modeling techniques for the various sources identified In paragraphs (1) to (6), inclusive. The noise contours shall be used as a guide for establishing a pattern of land uses in the Land Use Element that minimizes the exposure of community residents to excessive noise. The Noise Element shall Include implementation measures and possible solutions that address existing and foreseeable noise problems, if any. The adopted Noise Element shall serve as a guideline for compliance with the state's Noise Insulation Standards. C. RELATIONSHIP TO OTHER ELEMENTS The Noise Element is correlated with the Land Use, Circulation, and Housing Elements of the General Plan. The Land Use Element is related to the Noise Element in that noise can have a significant impact on land use. The Circulation Element is related to the Noise Element in that the majority of the noise created in Carlsbad is created by trains, planes or automobiles. The Housing Element relates to the Noise Element by promoting desirable residential environments which buffer existing and future residents from undesirable noise impacts. Consistent with state law, it is the policy of the City that the Noise Element be consistent with all General Plan Elements. II. SOURCES OF NOISE A. CIRCULATION Page 1 Underiine/Strikeout Exhibit Exhibit X-3 XOISE liLl-'M\-\T 1. ROADS Roadway traffic noise is the most extensive noise problem faced by Carlsbad. Barring any dramatic changes in truck or automobile usage pattems, it is likely that the amount of traffic in Carlsbad will grow with the City's population. New development is occurring adjacent to major roadways throughout the City. Unless precautionary measures are taken, serious noise problems could result. "Roadway traffic noise is the most extensive noise problem faced by Carlsbad." Vehicular noise has three main component sources: engine/transmission noise, exhaust noise and tire noise. The intensity of noise emissions from any given vehicle vAW vary with its size and other factors, such as speed, acceleration, braking, roadway grade and conditions of the roadway surface. Thus a busy downtown arterial with stop and go traffic is often noisier than an open highway with comparable traffic volumes. Noise contours have been prepared for all Circulation Element roadways in Carlsbad as shown on the current and future noise exposure maps (See Map 1: Existing Noise Exposure Contour Map and Map 2: Future Noise Exposure Contour Map). Interstate 5 has the greatest existing and projected roadway noise emissions. In addition, 1-5 impacts the greatest number of existing dwellings. There are a considerable number of existing single family and multi-family dwellings which are impacted by freeway noise levels in excess of 65 dBA CNEL. For these existing dwellings, noise attenuation is difficult. Constmction of solid barriers along the freeway is possible, but cost may be prohibitive. The City can, however, educate property owners as to the methods of insulating existing residential units from freeway noise through the use of barriers and insulation materials. The City's "Development Review: Noise Guidelines Manual" is a useful reference. While other routes within the City have a lesser impact than does 1-5, many roads will still have significant noise impact potential and new projects should therefore tie subject to noise impact evaluation. It Is important that new development fronting on major roadways be compatible with the recommendations of this element. The action plan section of this element contains the measures Intended to caused by traffic noise. avert future problems 2.

RAIL The Atchison, Topeka and Santa Fe (AT&SF) Railroad runs parallel to the coastline through its 6 1/2 mile length in Carlsbad. The railroad right- of-way is 100 feet wide throughout most of the area south of Tamarack Avenue and expands to 200 feet in width as it travels north of Tamarack through the downtown beach area and central business district. Cun-ently AMT-RAGtC-Amtrak operates several dally passenger trains between San Diego and Los Angeles. Additionally, a number of freight trains pass through Carisbad daily, some after 5 P.M. These evening and nighttime freight trains are of particular concern because they run during the hours when people are more sensitive to noise. By the end of 1993, it is projected that a commuter rail will run at least four daily trips from Oceanside to San Diego with two stops in Carlsbad. Ultimately, up to 20 commuter trains may travel through the City at high speed. There are several sources of railroad noise. The majority of the noise emanates from the locomotive (and its component systems, such as exhaust devices and cooling fans) and from the interaction between the rail and train wheels. The rhythmic clacking noise emitted by trains result from friction of the wheel at rail joints. Roughness on either the rail or wheel can also contribute to increased noise emissions. Safety devices such as warning whistles and wig-wags with bells used at grade crossings can contribute significantly to railroad noise. The Page 3 Underiine/Strikeout Exhibit Exhibit X-3 state of California Public Utilities Commission requires these warning signals as trains approach grade crossings to warn motorists and pedestrians. "A combined program of noise mitigating design and building sound insulation will help control future noise problems near the railroad." For existing residential units, noise reduction is a problem. It is often difficult and expensive to install sound insulation materials on existing structures. Also, the State Uniform Building Code standards for sound insulation apply only to new structures. Construction of noise barriers along the railroad right-of-way could attenuate noise levels significantly. However, the railroad right-of-way is owned by the AT&SF Railroad, whose consent would be necessary before any barrier could be constructed. Also cost and aesthetic impact may be prohibitive factors in the construction of noise barriers. The Land Use Element of the General Plan designates a substantial amount of land bordering along the railroad right-of-way for residential use. New residential development and nonresidential development wilt occur adjacent to the railroad. The City does have the ability to regulate site design and requires sound insulation for new development in the vicinity of the railroad. A combined program of noise mitigating design and building sound insulation will help control future noise problems near the railroad. New projects should maximize the physical separation of structures from the railroad tracks. Additionally, project design should stress the orientation of units away from the railroad, limiting or acoustically designing window openings onto the right-of-way, and construction of noise barriers such as solid walls, earthen berms, or berm/wall combinations, B. LAND USE To a great extent, the future ambient noise levels of the City will be determined by the type, intensity and location of future land uses. Future noise levels will also be affected by the construction of new roadways to serve new development and by land uses that generate noise. Noise levels may affect the desirability or livability of a community. Noise may also negatively impact the economic viability of a community by reducing the desirability of an area as a place to live, work, play, or shop. For these reasons, noise continues to be an important consideration of the City in future land use planning. 'To a great extent, the future ambient noise levels of the City will be determined by the type, intensity and location of future land uses." Some land uses are more compatible vrtth higher noise levels than are others. For example, schools, hospitals, churches and residences are generally considered more sensitive to noise intmsion than are commercial or industrial activities. To respond to the sensitivity of certain land uses to higher noise levels, this element includes policies to reduce noise impacts on noise-sensitive uses such as residences. It may be appropriate to develop noise-sensitive uses such as residences, hospitals, or churches in noisy areas. In these instances, it is important that the proper measures are used to reduce noise impacts. In all cases sensitive site plan design is to be used as the first method to reduce noise impacts on a project. Sensitive site plan design measures will include, for example, increasing the distance between the noise source and the receiver; placing non-noise sensitive uses such as parking areas, maintenance facilities, and utility areas between the source and the receiver; using non-noise sensitive structures, such as a garage, to shield noise sensitive areas; and, orienting buildings to shield outdoor spaces from a noise source. These and other noise mitigation techniques are discussed in more detail in the City's Noise Guidelines Manual available in the Planning Department. C. OTHER MOBILE SOURCES 1. OFF ROAD MOTORCYCLE NOISE Page 4 Underiine/Strikeout Exhibit Exhibit X-3 SOISE ELEMliM Motorcycle noise has been a problem in Carisbad. In particular, complaints have been registered against recreational use of dirt bikes or two-cycle engine motorcycles. The Police Department continues to enforce the prohibition of motorized off-road vehicles within the City, except as permitted at the Carisbad Raceway. Local jurisdictions have the authority to control loud or faulty mufflers, horn blowing, off-road vehicles and vehicle speed. Although noise limits may be set for off-road vehicles, they are rarely necessary since statutes against trespassing nearly always apply. Most trail bikes are not outfitted with the necessary lights, fenders, mufflers, sparit arresters or baffles required by law. Consequently they are not licensed and cannot be legally operated on public streets. Continued police enforcement against these unlicensed vehicles would likely reduce motorcycle noise on public streets. 2. MOTORBOAT This noise problem does not affect very many of Carisbad's residents. However, in response to noise complaints, the City has adopted a maximum speed limit for boats on the Agua Hedionda Lagoon and has purchased a boat for enforcement. The reduction in speed does reduce noise somewhat. If further control appears warranted, the City should consider setting curfews on the use of the lagoon or limit the types of boats which could use the lagoon. 3. MODIFIED VEHICLE EXHAUST SYSTEM Vehicles operating on city streets which have faulty or modified exhaust systems can cause significant local noise impacts, especially when operated in a "hot rod" manner: Continued enforcement of the vehicle code is encouraged in order to control this contributor to noise pollution. III. NOISE CONTOUR MAPS The noise contour maps contained herein, show 1990 and 2010 noise contours for the following transportation systems (See Maps 1: Existing Noise Exposure Contour Map (1990) and Map 2: Future Noise Exposure Map (2010): (1) Interstate 5 (2) State Highway 78 (3) Circulation Element Roadways of the Carlsbad General Plan (4) Rail (5) McClellan-Palomar Airport Substantial changes in traffic patterns or the availability of new noise contour data may indicate the need for revisions of this element. Consequently, the noise contours contained in this element should be reviewed and revised periodically. Noise levels for McClellan-Palomar Airport are expressed in terms of Community Noise Equivalent Level (CNEL), measured at 5 dB increments and are mapped for the range of §3 60 to 75± dBA CNEL. Noise levels for freeways, prime arterials and the railroad are expressed as CNEL down to the 60 dBA. All other transportation modes shown on the contour map are expressed as CNEL down to the 55 dBA. Community Noise Equivalent Level (CNEL) is based upon A-weighted noise level, number or duration of noise events, and time of occurrence throughout the 24 hour day. The CNEL measurement weights noise occurrences in the evening and nighttime greater than those in the daytime. Please refer to the Carlsbad "Noise Guidelines Manual" for more information regarding CNEL and general noise science. The airport's projected noise contours identified in the adopted Comprehen&ive - -McClellan- Palomar Airport Land Use Compatibility Plan for MoCieUan-P-alomar A if port are included in this element (See Map 3: Compatibility Policy Map: NgiseA4Fport-44oiS6- ContouFs-FutoPe-Gondrtions Map).

A. 3 A City which controls mobile sources of noise to help assure that mobile noise sources do not substantially contribute to the noise environment. B. OBJECTIVES B.I To achieve noise compatibility between Industrial/commercial and surrounding land uses and achieve an acceptable noise environment in industrial/commercial areas. B. 2 To achieve noise impact compatibility between land uses through the land use planning/development review process. 8.3 To actively control mobile noise violations. C. IMPLEMENTING POLICIES AND ACTION PROGRAMS Page 6 Underiine/Strikeout Exhibit Exhibit X-3 SOISE E}J-:ME.\E C.I Encourage the development of compatible land uses in areas which are subject to excessive noise levels. C.2 Develop specific noise standards for use in revieviflng noise sensitive development. C.3 Require the use of project design techniques, such as, increasing the distance between the noise source and the receiver; placing non-noise sensitive uses such as parking areas, maintenance facilities, and utility areas between the source and the receiver; using non- sensitive structures, such as a garage, to shield noise sensitive areas; and, orienting buildings to shield outdoor spaces from a noise source to minimize noise impacts during any discretionary review of a residential or other noise sensitive project. C,4 Continue to enforce the State Motor Vehicle Code as it applies to excessive noise. The Carisbad Police Department should continue to reduce the number of excessively noisy vehicles on city streets. The Department should also continue to deter persons from operating their motor vehicles in a noisy manner. C.5 Enforce the policy of the City that sixty (60) dBA CNEL is the exterior noise level to which all residential units should be mitigated. 65 dBA CNEL is the maximum noise level to which residential units subject to noise from McClellan-Palomar Airport should be permitted. Additional disclosure actions for new development in the Airport influence Area as depicted in the McClellan-Palomar Airport ,Land Use Compatibiiitv Plan (ALUCP), such as favigation easements, deed restrictions, recorded notice, etc.J may be required of developers/sellers of noise impacted residential units. For residential properties identified as requiring a noise study, a study shall be prepared by an acoustical professional. This study shall document the projected maximum exterior noise level and mitigate the projected exterior noise level to a maximum allowable noise level as identified in this policy. Interior noise levels should be mitigated to 45 dBA CNEL when openings to the exterior of the residence are open or closed. If openings are required to be closed to meet the interior noise standard, then mechanical ventilation shall be provided. If the acoustical study shows that exterior noise levels cannot be mitigated to the level allowable as identified in this policy or less, the development should not be approved without one or more of the following findings: (1) Changes or alterations have been required in, or incorporated into, the project which avoid or substantially lessen the significant environmental effect (noise). (2) Changes or alterations to avoid or substantially lessen the significant environmental effect (noise) are within the responsibility and jurisdiction of another public agency and not the City of Carisbad. Such changes have been adopted by such other agency or can and should be adopted by such other agency. (3) Specific economic, social, or other considerations make infeasible the mitigation measures or project alternatives to avoid or substantially lessen the significant environmental effect (noise). If a project is approved with exterior noise levels exceeding the level allowable pursuant to this policy, all purchasers of the impacted property Shalt be notified in writing prior to purchase, and by deed disclosure in writing, that the property they are purchasing is, or will be, noise impacted and does not meet Carlsbad noise standards for residential property. Notwithstanding project approval, no residential interior CNEL should exceed 45 dBA. C.6 Require that a "Noise" Study be submitted with all discretionary applications for Page 7 Underiine/Strikeout Exhibit Exhibit X-3 SOISE EI.KMESI residential projects of five or more single family dwelling units or any multiple family dwelling units located within or 500-feet beyond the 60 dBA CNEL noise contour lines as shown on Map 2: Future Noise Exposure Contour Map. C.7 Enforce the policy of the City that site design techniques such as increasing the distance between the noise source and the receiver; placing non-noise sensitive uses such as parking areas, maintenance facilities and utility areas between the source and the receiver; using non-noise sensitive structures, such as a garage, to shield noise-sensitive areas; and orienting buildings to shield outdoor spaces from a noise source, be the first tool used to mitigate noise impacts on noise sensitive land uses rather than the construction of walls or berms. C,8 Recognize that mitigation of existing or future noise impacts from Circulation Element roadways, AT&SF railroad or McClellan-Palomar Airport for existing or future development within the City, shall not be funded by the City. However, the City shall assist applicants with the processing of necessary permits for mitigating noise on private property, which permits may include right-of-way permits, encroachment permits, retaining wall permits and zoning variances. The City shall also assist property owners in the establishment of assessment districts, to fund noise mitigation improvements, in accordance with established City policies and procedures, C.9 Discourage the exclusive use of noise walls in excess of 6 feet in height as mitigation for noise along Circulation Element roadways. CIO Utilize natural barriers such as site topography or constmcted earthen berms to mitigate noise on a project. When noise walls are determined to be the only feasible solution to noise mitigation, then the walls shall be designed to limit aesthetic impacts. When over-height walls are necessary to mitigate noise, a berm/wall combination vrtth heavy landscaping, a terraced wall heavily landscaped, or other similar innovative wall design technique shall be used to minimize visual impacts. CIRCULATION ROADS A. GOAL To provide a roadway system that does not subject surrounding land uses to significantly adverse noise levels. B. OBJECTIVE To design and manage all roadways to maintain acceptable noise levels. C. IMPLEMENTING POLICIES AND ACTION PROGRAMS C.I Take measures to reduce traffic noise on streets throughout Carisbad. This will include continued enforcement of applicable sections of the California Vehicle Code regarding equipment and/or operation of motor vehicles. C.2 Consider noise impacts in the design of road systems and give special consideration to those road corridors in scenic or noise sensitive areas. C.3 Review traffic flow systems and synchronize signalization, wherever possible to avoid traffic stops and starts, which produce excessive noise, and to adjust traffic flow to achieve noise levels acceptable to surrounding areas. C.4 Apply the residential noise policies of this element in the review of proposals for the construction or improvement of any roadway, railroad, transit system or other noise producing facility. AIRPORT A. GOAL A City that achieves long-term compatibility between the airport and surrounding land use. Pages Underiine/Strikeout Exhibit Exhibit X-3 SOISE I J.EMESI B.

A technique used in the State of California for quantifying aircraft and community noise levels. CNEL is based on A-weighted noise measurements, in which both the magnitude of noise and frequency of occun-ence are measured. It incorporates factors of amplitude and the pitch of noise, hearing sensitivity of the human ear, duration of noise, and time of day penalty factors. The CNEL measure weights nighttime and evening noise occurrences greater than daytime ones. A unit for measuring the relative loudness of sounds equal approximately to the smallest degree of difference of loudness ordinarily detectable by the human ear. An A-weighted decibel compensates for the hearing sensitivity of humans by discriminating against the lower frequencies according to an approximate relationship to the sensitivity ofthe human ear.

SECTION 1207 /HCO 1& HCD 2] SOUND TRANSMISSION 1207.1 Purpose and scope. The puipose of this seclion is lo esiablish uniform minimum noise insulation performance standards lo protect persons wllhin hotels, motels, dormitories, apartment houses and dwellings other than detached sin- gle-family dweUings from the effects of excessive noise, includ- ing, but not limiled to, hearing loss or impairment and interference wilh speech and sleep. This seclion simU apply to all buildings for which applications for building permits were made subsequent lo August 22,1974. 1207.2 Definitiotts. The following special definitions shall apply to this section: SOUND TRANSMISSION CLASS (STC) is a single-number rating used to compare walls, floor-ceiling assemblies and doors for iheir sound-insulating properties wilh respect to speech and small household appliance noise. The STC is derivedfrom laboratory measurements of sound transmission loss across a series of 16 lest bands. Laboratory STC ratings should be used to Ihe greatest extent possible in determining that Ihe design complies with ihis sec- tion. FIELD SOUND TRANSMISSION CLASS (FSTC) is a sin- gle-number rating similar to STC, except that the transmission loss values used lo derive the FSTC are measured in the field. All sound transmitted from the source room to the receiving room is assumed to be through ihe separating wall or floor-celling assembly. This section does nol require determination of the FSTC, and field-measured values of noise reduction should not be reported as transmission loss. IMPACT INSULATION CLASS (IIC) is a single-number rat- ing used 10 compare the effectiveness of floor-ceiling assem- blies in providing reduclion of impact-generated sounds such as footsteps. The IIC is derivedfiom laboratory measurements of intact sound pressure level across a series of 16 test bands using a standardized tapping machine. Laboratory HC ratings should be used lo the greatest extent possible in determining that the design complies wilh this section. FIELD IMPACT INSULATION CLASS (FIIC) is a sin- gle-number rating similar lo Ihe UC, except thai the impact sound pressure levels are measured in the field NOISE ISOLATION CLASS (NIC) is a single-number raHng derived from measured values of noise reduclion between two enclosed spaces that are connected by one or more paths. The NIC is not acfjusled or normalized lo a standard reverberation time. NORMAUZED NOISE ISOLATION CLASS (NNIC) is a single-number rating similar to the NIC, except that the mea- sured noise reduction values are normalized to a reverberation time of one-ha^second NORMAUZED A-WEIGHTED SOUND LEVEL DIFFER- ENCE (Dn) means for a specified source mom sound spec- trum, Dn is the difference, in decibels, between the average sound levels produced in Iwo rooms after adjuslmenl to the expected acoustical conditions when the receiving room under test is normally furnished. DAY-NIGHT AVERAGE SOUND LEVEL (Un) is the A-weighted equivalent coruinuous sound exposure level for a 24-hour period wilh a 10 db adjustment added to sound levels occurring during nighttime hours (10 p.m. to 7 a.m.). COMMUNITY NOISE EQUIVALENT LEVEL (CNEL) is a metric similar ta the Ldn, except that a 5 db adjustment is added lo ihe equivalent continuous sound exposure level for evening hours (7p.m. to 10p.m.) in addition to the 10 db night- time adjustment used in the Ldn. I2Q7.2.I Masonry, The sound transmission class of con- crete masonry and clay masonry assemblies shall be calcu- lated tn acconJance with TMS 0302 or determined through testing in accordatKe with ASTM E 90. 1297.3 Relevant standards.

Such costs shall be chargeable to the con^jlainanl if the field tests show coit^liance with this chapter. If the tests show noncompliance, testing costs shall be borne to the owner or builder. 1207.5 Local modification. The governing body of any city or county or city and county may, by ordinance, adopt changes or modifications to the requirements of this section as set forth in Section 17922.7 of the Health and Safety Code. 1207.6 IiUerdwelling sound transmission control 1207.6.1 Wall and floor-ceiling assemblies. Hfi/I and floor-ceiling assemblies separating dweUing units or guest rooms fiom each other and from public or service areas such as interior corridors, garages and mechanical spaces shall provide airborne soimd insulation pr walls, arid both air- borne and impact sound insulation for floor-ceiling assem- blies. Exception: Impact sound insulation is not required for floor-ceiling assemblies over nonhabitable rooms or spaces nol designed lo be occupied, such as garages, mechanical rooms or storage areas. 1207.7Airborne sound insolation. All such acoustically rated separating wall and floor-ceiling assemblies shall provide air- borne sound insulation equal to that required lo meet a sound transmission class (STC) rating of 50 based on laboratory tests as defined in ASTM B90andE 413. Field-tested assemblies shall meet a noise isolation class (NIC) rating of 45 fbr occu- pied units and a normalized noise isolation class (NINIC) rat- ing of 45 for unoccupied units as defined in ASTM E 336 and E 413. ASTM E 597 may be used as simpl^ed procedure for field tests of the airborne sound isolation between rooms in uruxcu- pied buildings. In such tests, the minimum value ofDn is 45 db for compliance. Entrance doors from interior corridors together with their perimeter seals shall have STC ratings nol less than 26. Such tested doors shall operate normally with commercially {mail- able seals. Solid-core wood-slab doors J% inches (35 mm) thick mini- mum or 18 gauge insulated steel-slab doors wilh compression seals all arourui, including the threshold, may be considered adequate without other substantiating InformatiorL Field tests of corridor walls should not include segments with doors. If such tests are impractical, however, the NIC or NNIC rating for the composite wall-door assembly shall not be less than 30. Penetrations or openings in construction assemblies for pip- ing, electrical devices, recessed cabinets, bathtubs, soffits or heating, ventilating or exhaust ducts shall be sealed, lined, insulated or otherwise treated to maintain the required ratings. 1207.8 Impact sound insulation. AU acoustically rated sepa- rating fioor-ceiling assemblies shall provide impact sound insulation equal to that required to meet a IIC rating 50 based on laboratory tests as defined in ASTM E 492 and E 989. Field-tested assemblies shall meet a field impact insulation class (FllC) rating of 45 for both occupied and unoccupied units as defined in ASTM E1007andE 989, wiOi ihe exception that the measured impact sound pressure levels shall not be normalized lo a standard amount of absorption in the receiving room. Floor coverings may be included in the assembly lo obiain Ihe required ratings. These coverings must be retained as a per- manent part ofthe assembly and may be replaced only by olher floor coverings that provide tke required impact sound insula- tion. 1207.9 Tested assemblies. Laboratory-tested wall or floor-celling designs having STC or IIC ratings of 50 or more may be used by the building official to determine compliance wiA this section during plan review phase. Field tests shall be required by the building official when evidence of sound leaks or flanking paths is noted, or when the separating assembly is not built according to the approved design. Generic sound transmission control systems as listed in the Catalog of STC and IIC Ratingsfor Wall and Floor-Ceiling Assemblies, as published by the Office erf Noise Control, Cali- fomia Department of Health Services, or the Hre Resistance Design Manual, as published by the Gypswn Association, may be used to evaluate construction assemblies for their sourid transmission properties. Other tests from recognized laborato- ries may also be used. When ratings for essentially similar assemblies differ, and when ratings are below STC or HC 50, field testing may be used lo demonstrate that the building com- plies with this section. Fbr field testing, rooms should ideally be large and reverber- ant Jbr reliable measurements lo be made in all test bands. This is often not possible fbr bathrooms, kitchens, hallways or rooms with large amounts of sound-absorptive materials. Field test results should, however, report the measured values in atl bands, noting those which do nol meet relevant ASTM criteria for diffusion. It should be noted that STC ratings do nol adequately char- acterize the sound insulation of construction assemblies when the intruding noise is predominantly low-pitched, as is often produced by amplified music or by large pieces of mechanical equipment. It should also be noted that the transmission of impact sound from a standardized lapping machine may vary consitlerably for a given design due to differences in specimen size, flanking transmission through associated structure and the acoustical response of the room beiow. Laboratory UC values should therefore be used with caution when estimating the perfor- mance cf hard-sutfaced floors in the field. Additionally, HC ratings may not always be adequate to characterize the subjec- tively annoying creak or boom generated by footfalls on a lum- ber floor. 1207.10 Certification. Field testing, when required, shall be done under the supervision ofa person experienced in the field of acoustical testing and engineering, who shall forward test results to the building qfficial showing that the sound isolation requirements stated above have been met. Documentation of 2010 CALIFOHNIA BUILDING CODE 597 Strikeout/Underline Exhibit Noise Guidelines Manual, September 1995 Exhibit X-6 INTERIOR ENVIROrmENT field test results should generally follow the requirements out- lined in relevant ASTM standards. 1207.11 Exterior sound transmission control, 1207.11.1 Application. Consistentwith local land-use stan- dards, residential structures located in noise critical areas, such as proximity to highways, county roads, city streets, railroads, rapid transit lines, airports or industrial aretis, shall be designed to prevent the intrusion of exterior noises beyond prescribed leveb. Proper design shall include, but shall not be limiled to, orientation ofthe residential struc- ture, setbacks, shielding and sound insulation cf the build- ing Itself. 1207.11.2 Allowable interior noise levels. Interior noise levels attributable to exterior sources shall not exceed 45 db in any habitable room. The noise metric shall be either the day-night average sound level (Ldn) or the community noise equivalent level (CNEL), consistent with the noise element ofthe local general plan. Note: Ldn is the preferred metric for implementing these standards. Worst-case noise levels, either existing or future, shall be used as the basis for determining compli- ance with this section. Future noise levels shall be pre- dicted fbr aperiod <^ at least 10 years from the time of building permit {^plication. 1207.113 Airport noise sources. Residential structures to be located where Ihe anrwal Ldn or CNEL (as defined in Title 21, Division 2.5, Chapter 6, Article I, Section 5001, Callfomia Code of Regulations) exceeds 60 db shall require an acoustical analysis showing that the proposed design will achieve prescribed allowable interior levei For pub- lic-use airports or heliports, the Ldn or CNEL shall be determinedfrom the airport land-use plan prepared by the county wherein the airport is located. For military bases, the Ldn shall be detennined from the facility Air Installation Compatible Use Zone (AICUZ) plan. For all other airports or heliports, or public-use airports or heliports for which a land-use plan has nol been developed, the Ldn or CNEL shall be determined from the noise element ofthe general plan ofthe local jurisdiction. When tdrcraft noise is not the only significant source, noise levels from all sources shall be added lo detennine the composite site noise level 1207.11.4 Other noise sources. Residential structures to be located where the Ldn or CNEL exceeds 60 db shall require an acoustical analysis showing that the proposed design will limit exterior noise to the prescribed allowable interior level The noise element ofthe local general plan shall be used to the greatest extent passible to identify sites with noise levels potentiaUy greater than 60 db. 1207.12 CompUance, Evidence of compliance shall consist of submittal of an acoustical analysis report, prepared under the supervision of a person experienced in the field qf acoustical engineering, with the application for a building permit. The report shall show topographical relationships of noise sources and dwelling sites, identification of noise sources and their characteristics, predicted ttoise spectra and levels at the exte- rior of the proposed dwelling structure considering present cmd future land usage, basis for the predlaion (measured or obtained from published data), noise attenuation measures to be applied, and an analysis cfthe noise itisulation effectiveness ofthe proposed construction showing that the prescribed ulte- rior noise level requirements are met. If interior allowable noise levels are met by requiring that windcnvs be unopenable or closed, the design for the structure must also specify a ventilation or air-conditiorung system to provide a habitable interior environment. The ventilation sys- tem must not compromise the dwelling unit or guest mom noise reduction. 1207,13 Field testing. When inspection indicates lhat the con- struction is not in accordance wilh the approved design, or that the noise reduction is compromised due to sound leaks orfiank- ing paths, field testing may be required. A test report showing compliance or noncompliance with prescribed Interior allow- able levels shall be submitied to the building official. Measurements of outdoor sound levels shall generally fol- low the guidelines in ASTM E1014. I^ld measurements ofthe A-weighted airborne sound insu- lation of bmldingsfrom exterior sources shall generaUy follow the guidelines in ASTM E 966. For the purpose of this standani, sound level differences measured in unoccupied tmits shaU be normalized to a receiv- ing roam reverberation time of one-half second. Sound level differences measured in occupied units shall not be normalized lo a standard reverberation time. SECTION 1208 INTERIOR SPACE DIMENSIONS 1208.1 Minimmn room widths. Habitable spaces, other than a kitchen, shall oot be less than 7 feet (2134 mm) ui any plan dimension. Kitchens shall have a clear passageway of not less than 3 feet (914 mm) between counter fronts and ^pliances or counter fronts and walls.
