Within the Medium- and High -Density Residential designation, existing residential units legally built in excess of the dwelling
units per acre standard may be rebuilt at the same higher density subject to other zoning code standards. The allowable
density or number of units to be redeveloped would be limited to the 1990 General Plan density with a 25% incentive bonus for
Medium -Density or a 50% incentive bonus for High -Density; or the existing number of units, whichever is less.

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.

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.

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
