The Very -Low Traffic category allows commercial uses with daily trip generation rates of less than 3 trip ends per 1,000 square -feet of floor area. Allowable uses under this standard include mini -warehouse developments. The Low Traffic category allows commercial uses with daily trip generation rates between 3 and 20 trip ends per 1,000 square -feet of floor area. Allowable uses under this standard include general offices, hospitals, motels, hotels, and furniture stores. The Moderate Traffic category allows commercial uses with daily trip generation rates of between 20 and 75 trip ends per 1,000 square -feet of floor area. Allowable uses within this standard include general retail uses, car dealers, medical and government offices, auto repair, and dry cleaners. The High Traffic category allows commercial uses with daily trip generation rates in excess of 75 trip ends per 1,000 square -feet of floor area. Allowable uses in this category include restaurants, convenience markets, service stations, and banks. LAND USE ELEMENT • PAGE LU -27 General Commercial The General Commercial designation is intended to permit a wide range of commercial uses which serve both local and regional needs. These areas should have exposure and access to major transportation routes since significant traffic can be generated. General Commercial areas should be insulated from the most sensitive land uses, either through buffers of less sensitive uses or on- site mitigation techniques. The most intense commercial uses should be encouraged to locate on sites of adequate size to allow appropriate mitigation. Appropriate uses include those found in the Neighborhood Commercial designation plus junior department stores and retail clothing stores, theaters, restaurants, hotels and motels, and automobile sales and service establishments. In the General Commercial designation, the allowable floor area ratios (FAR) are 0.20 for high traffic generating uses, 0.30 for moderate traffic generating uses, 0.40 for low traffic generating uses, and 0.75 for very low traffic generating uses (see Table LU -4). Development within this range would typically result in combinations of one- and two-story commercial buildings. Buildings in excess of two stories may be permitted in select areas where the additional height would not impact surrounding uses. maximum numoer or stories is tour. Because of the wider range of uses and more building intensity permitted in the General Commercial designation, the population density within this designation will also be more intense than that found in the Neighborhood Commercial designation. The standard mix of uses in this designation would generate an average population density of 27 employees per acre. A development that consisted of office use only would require up to 60 employees per acre. Residency hotels such as single room occupancy (SRO) hotels may be located in the General Commercial district. These hotels would have resident populations of up to 117 persons per acre. PAGE LU -30 + LAND USE ELEMENT Costa Mesa Gen Institutional uses are also appropriate in the General Commercial designation, provided that land use compatibility and traffic issues have been addressed. Institutional uses would require a discretionary approval. As complementary uses, residential and other noncommercial uses may be allowed through the Planned Development process. Residential densities in planned development projects shall not exceed 20 dwelling units per acre. The corresponding population density is up to 50 persons per acre. Noncommercial uses would be subject to the same floor area standards as commercial uses in this designation. The adoption of General Plan amendment (GP -02-06) established a site-specific FAR of 0.40 and trip budget of 186 AM peak hour trips and 281 PM peak hour trips for the 4.4 -acre site located at 1626/1640 Newport Boulevard. These two standards allow the development of medical office uses or similar "moderate -traffic" generating uses provided that the site-specific trip budget is not exceeded. Facilities that transfer, store, or dispose of hazardous wastes that are generated at another source (off-site) are most appropriately located in the Industrial Park and Light Industry land use designations; however, a facility with a purpose and scale of operation that is compatible with this commercial designation may be allowed pursuant to the issuance of a conditional use permit. General Commercial developments are mainly located along major arterials such as Harbor Boulevard, East 17th Street and Bristol Street south of the 1-405 and SR -55. Compatible zoning districts include CL, C1, C1 -S, C2, PDC, AP, MU and P. Commercial Center The Commercial Center designation is intended for large areas with a concentration of diverse or intense commercial uses serving local and regional needs. Appropriate uses include a wide variety and scale of retail stores, professional offices, restaurants, hotels and theaters. Intense service uses, such as automobile repair and service, should be discouraged. Because of the large service area, direct access to major transportation corridors is essential. Development within this designation is intended for a variety of intensities ranging from one- to four-story buildings. The allowable floor area ratios are 0.25 for high traffic generating uses, 0.35 for moderate traffic generating uses, 0.45 for low traffic generating uses, and 0.75 for very -low traffic generating uses. In conjunction with approval of Home Ranch Alternative A, a site-specific FAR of 0.41 was established for the 17.2 -acre IKEA site. (IKEA is a large retail/warehouse use.) This property is located at the southeast corner of South Coast Drive and Harbor Boulevard. A trip budget of 43 AM peak hour trips and 431 PM peak hour trips was also adopted for the IKEA site. A maximum allowable FAR of 0.40 for office uses was also established for the remaining 45.4 acres located south of South Coast Drive. The combined trip budget for this site and the 14.5 -acre Industrial Park parcel located to the north of South Coast Drive is 1,593 AM peak hour trips and 1,569 PM peak hour trips. The North Costa Mesa Specific Plan provides more FAR, building height, and trip budget information for Segerstrom Home Ranch (Area 1). LAND USE ELEMENT + PAGE LU -31 TABLE LU -8 INDUSTRIAL BUILDING INTENSITY STANDARDS The Very -Low Traffic category allows industrial uses with daily trip generation rates of less than 3 trip ends per 1,000 square -feet of floor area. Allowable uses under this standard include mini -warehouse developments. The Low Traffic category allows industrial uses with daily trip generation rates between 3 and 8 trip ends per 1,000 square -feet of floor area. Allowable uses under this standard include a wide range of manufacturing and assembly uses. The Moderate Traffic category allows uses with daily trip generation rates between 8 and 15 trip ends per 1,000 square -feet of floor area. Allowable uses under this standard include support of office, research and business park type uses. The High Traffic category allows uses with daily trip generation rates in excess of 15 trip ends per 1,000 square -feet of floor area. Allowable uses under this standard include support commercial service uses and restaurants. Industrial Park The Industrial Park designation is intended to apply to large districts that contain a variety of industrial and compatible office and support commercial uses. Industrial parks are characterized by large parcels and landscaped setbacks which lend to the creation of a spacious campus -like environment. Industrial parks must have proximity to freeways and other major transportation routes in order to provide the accessibility they require. An internal circulation system consisting of lesser highways is also necessary to accommodate the vehicle demands created. Industrial parks have major physical separations from areas designated for other uses in order to maintain their distinctiveness and avoid potential land use incompatibilities. Development within this designation would consist of one- and two-story buildings. Additional height may be permitted when compatible with adjacent development and the uses are consistent with other constraints such as height limits near John Wayne Airport. The Industrial Park portion of the Home Ranch site may include buildings up to five stories in height near the center of the development. The North Costa Mesa Specific Plan provides more building height information for Segerstrom Home Ranch (Area 1). In the Industrial Park designation, the allowable floor area ratios are 0.20 for high traffic generating uses, 0.30 for moderate traffic generating uses, 0.40 for low traffic generating uses, and 0.75 for very low traffic generating uses. The exception to the above standards is the 14.5 -acre Segerstrom Home Ranch site. This site is governed by the maximum allowable FAR standard of 0.40, a LAND USE ELEMENT • PAGE LU -V Development within this designation would be characterized by a combination of one- and two-story buildings. Because of the location of Light Industry areas and their proximity to residential uses, higher buildings should be restricted to areas that will not impact the surrounding residential uses. The allowable building intensity standards are floor area ratios (FAR) of 0.15 for high traffic generating land uses, 0.25 for moderate traffic generating land uses, 0.35 for low traffic generating uses, and 0.75 for very -low traffic generating uses. The average population density would be 31 employees per acre, and 53 employees per acre for office uses based on standards provided in Table LU -5. Additionally, this type of development is intended to revitalize areas of the city, without exceeding the capacity of the General Plan transportation system. Mixed - Commercial uses may be allowed provided that the commercial use is determined to be complementary to the industrial area. Commercial recreational uses may also be appropriate under the same condition. Institutional uses may also be appropriate in this industrial designation provided that land use compatibility and traffic issues have been addressed. Institutional uses would require a discretionary review and approval process. Combinations of residential, institutional and commercial uses may be allowed through the Planned Development zone process. Floor area ratios and population densities for commercial projects would be similar to the Neighborhood Commercial land use designation. Residential densities in Planned Development projects are not to exceed 20 dwelling units per acre. The corresponding population density range is up to 50 persons per acre. The largest concentrations of Light Industry land are in the southwest industrial area along Placentia Avenue between 19th and Victoria Streets.

Facilities that transfer, store, or dispose of hazardous wastes that are generated at another source (off-site) may be allowed in this land use designation, subject to the issuance of a Conditional Use Permit. LAND USE ELEMENT t PAGE LU -39 Costa Mesa Gene�erralPlan Compatible zoning districts include MG, PDI, MU and CL INSTITUTIONAL AND OPEN SPACE Costa Mesa's large portion of land set aside for public, semi-public, and open space type uses is designated under one of three land use designations: Public/Institutional, Golf Course, and Fairgrounds. Public/institutional The Public/Institutional designation is intended for both publicly and privately owned land that provides recreation, open space, health and educational opportunities as well as uses that provide a service to the public. Since this designation includes many different types of land uses, the land use map has been further labeled to identify the individual uses within this designation. Areas that are included in this designation are park sites, health care facilities, educational institutions, religious facilities, fairgrounds, and public facilities. As many of the uses in this designation are recreational and open space in nature, levels of building intensity are minimal. The maximum building intensity for this designation is a floor area ratio of 0.25 and a population density of 44 employees per acre. The adoption of GP -02-5 established a site-specific floor area ratio of 0.35 for the 9.44 -acre Civic Center. This General Plan amendment recognized existing development intensity and allowed an expansion to the Police Facility. The Civic Center contains the 5 -story City Hall, the 2 -story Police Facility, Fire Station Number 5 and the Communications Center. Compatible zoning districts include I&R, I&R-S, and P. Golf Course Three golf courses are located within the City's planning area. Two of these, the City's course and Mesa Verde Country Club, are located within the current City limits. Santa Ana Country Club is in the unincorporated area east of Newport Boulevard. Because of the large area devoted to open space, the building intensity for this designation is a floor area ratio of 0.01. The compatible zoning district is I&R PAGE LU -40 • LAND USE ELEMENT Fairgrounds This designation recognizes the unique land uses associated with the 150 -acre Orange County Fairgrounds and Exposition Center. This property is owned by the State of California, and the City has limited permitting authority. However, it is the goal of the City to work closely with the State to ensure that the impacts associated with the development and use of this site are appropriately addressed and mitigated. Of particular concern are traffic -related impacts and land use compatibility. The maximum allowable floor area ratio for this designation shall be 0.10. The compatible zoning district is I&R. GENERAL PLAN/ZONING RELATIONSHIP The relationship between the 2000 General Plan land use designations and zoning districts is shown in Table LU -9. This table indicates how properties should be zoned to be consistent with the General Plan Land Use Plan Map. As presented in the table, there are 15 General Plan land use designations and 21 zoning categories. HOUSING AND EMPLOYMENT PROJECTIONS Providing a land use arrangement that encourages a correlation of employment and housing opportunities is a local and regional responsibility. Providing sufficient commercial land to support residential development is primarily a local responsibility, although commercial uses which serve regional needs are provided as well. Sufficient land must also be established to meet the recreational needs of the local community, although regional needs are often accommodated by land within individual cities. Refer to Table LU -3, Population, Housing, and Employment, to review historical data for Costa Mesa's population, number of housing units, and employment opportunities.

NOISE ELEMENT • PAGE N-7 Costa Mea Gen_eraf Plan addition to establishing noise emission standards for interstate commerce activities. STATE NOISE STANDARDS The Office of Noise Control in the State Department of Health Services has developed criteria and guidelines for local governments to use when setting standards for human exposure to noise and preparing noise elements for General Plans. These guidelines include noise exposure levels for both exterior and interior environments. In addition, Title 25, Section 1092 of the California Code of Regulations sets forth requirements for the insulation of multiple -family residential dwelling units from excessive and potentially harmful noise. The State indicates that locating units in areas where exterior ambient noise levels exceed 65 CNEL is undesirable. Whenever such units are to be located in such areas, the developer must incorporate into building design construction features which reduce interior noise levels to 45 dBA CNEL. Tables N-2 and N-3, below, summarize standards adopted by various State and Federal agencies. Table N- 3, Noise and Land Use Compatibility Matrix, presents criteria used to assess the compatibility of proposed land uses with the noise environment. Table N-4, State Interior and Exterior Noise Standards, indicates standards and criteria that specify acceptable limits of noise for various land uses throughout Costa Mesa. These standards and criteria will be incorporated into the land use planning process to reduce future noise and land use incompatibilities. These tables are the primary tools which allow the City to ensure integrated planning for compatibility between land uses and outdoor noise. CITY NOISE STANDARDS The City of Costa Mesa maintains a comprehensive Noise Ordinance within the City Code which sets standards for noise levels citywide and provides the means to enforce the reduction of obnoxious or offensive noises. NOISE ORDINANCE The City Noise Ordinance establishes outdoor and indoor noise standards. The ordinance is designed to control unnecessary, excessive and annoying sounds generated on one piece of property from impacting an adjacent property, and to protect residential areas from noise sources other than transportation sources. The basic noise standards contained in Table N-2, City Noise Ordinance Standards -Residential, below, are for the daytime period (7:00 a.m. to 11:00 p.m.) and apply to both outdoor and indoor residential areas. Between the hours of 11:00 p.m. and 7:00 a.m., the noise standards are 5 dBA more stringent for exterior areas and 10 dBA more stringent for indoor areas. The Citv Noise standards.
