Brijandez, Roberto's Automotive Repair Shop The request is to operate an automotive repair facility (minor auto repair) in an existing building at 1655 Broadway within the C-C-P (Central Commercial/Precise Plan) zone. The C-C zone allows minor automotive repair through the conditional use permit process. BACKGROUND Conditional use permits for minor automotive repair in eXlstmg buildings are generally considered by the Zoning Administrator. However, staff has concerns regarding the suitability of this use in this particular location. As a result, the application has been forwarded to the Planning Commission for consideration. It should be noted that the use has physically been relocated to this address, although it apparently will not be put into operation unless this permit is approved. The Enviromnental Review Coordinator has determined that this project IS exempt from enviromnental review under CEQA as a Class 5 exemption. ISSUES 1. Noise impacts on the adjacent trailer park to the east; 2. Limited size of facility and resultant potential for work to occur outside the building; 3. Compatibility of auto repair use with surrounding general retail and service commercial tenants. RECOMMENDATION That the Planning Commission adopt attached Resolution PCC-97 -1 0 denying the conditional use permit for a minor automotive repair facility at 1655 Broadway, Suite 15, in accordance with the findings contained therein. Page 2, Item ..A..... Meeting Date 8/28/96 DISCUSSION Site Characteristics The project site consists of a 1,904 sq. ft. space within an existing 4 acre commercial strip center located at the southeast corner of Broadway and Anita Street. Other existing tenants within the center include retail and office uses, a laundromat, and two automotive repair facilities at the north end of the building facing Anita Street. Zoning and Land Use North - South - East - West - C-C-P C-C-P R-2-P C-C-P Commercial Center Commercial Center Residential Trailer Park Commercial center The project site is located approximately in the center of an existing commercial strip center; one adjoining tenant space is currently occupied by a sewing machine shop; the other adjoining space is currently vacant. The shopping center is bounded by Anita Street to the north and Broadway to the west; used automobile sales businesses are located on the property to the south. The easterly adjacent property is a residential trailer park Proposal The proposal is for a minor automotive repair facility to include tune-ups, oil changes, and lubrication services for passenger cars and light duty pick -up trucks. The business would operate Monday through Friday from 9:00 a.m, to 7:00 p,m., and Saturday and Sunday from 10:00 a,m. to 5:00 p.m., with the last half-hour of each day reserved for shop and equipment clean-up and paperwork. Customer service areas are at the front of the suite and the vehicle service area is at the rear. The applicant states that customers would arrange for work and sign work orders (presumably while me vehicle is parked in front of the shop), and then would drive the vehicle to the work bay entrance, where it is picked up by an employee and moved into one of the service areas. The facility would have four employees, and the applicant estimates that an average of four vehicles per hour would be serviced on a moderate-volume day. The service area contains two lifts, and has enough space to service a maximum of four vehicles at anyone time. Page 3, Item ...L Meeting Date 8/28/96 ANALYSIS Staff has three basic concerns with this proposal. One concern is with noise, which is a potential concern with all auto repair uses. The other two concerns are related to the size and location of this particular facility, Size in terms of the potential for work to occur outside the building, and location in terms of situating an auto repair operation in the middle of general retail and service commercial tenant spaces. The following issues are interrelated, but have been separated for discussion purposes: Noise A primary concern is noise. As noted, the service area is accessed through a roll-up door at the rear of me space, facing the trailer to the east. Since the roll-up door would remain open during hours of operations, the noise associated with testing vehicle engines (e.g. "gunning" the engine) and pneumatic wrenches, for example, could negatively impact the adjacent residents. There is only a wood fence separating the two properties, with trailers situated adjacent to and above the fence line, only 50 ft. distant from the roll-up door. The applicant has provided a noise study in order to evaluate potential noise impacts on the easterly adjacent residents, as well as on the two adjoining tenant spaces (see attachment). Although the study concludes that the operations would be expected to comply with the City noise ordinance, it found that noise created by both pneumatic wrench use and the revving of engines would exceed acceptable limits. In order to conclude that the sound level at the adjacent trailer park would comply with City standards, the study assumes that revving engines and the use of pneumatic wrenches would not occur for more than 15 minutes per hour. Staff is concerned with establishing a use that has the potential to create adverse noise impacts based upon factors which in essence cannot be reasonably controlled or monitored, i.e" the amount of time in any hour that engines may be revved or pneumatic wrenches may be used. Also, although the higher sound levels might occur only intermittently and less than 15 minutes in any hour, the noises would nonetheless likely represent a disturbance to the adjacent residents. At best, this is a marginal location from a noise perspective. Limited Size of Facilitv As noted earlier, the total size of the tenant space is 1,900 sq, ft., and the area available inside to park vehicles is just about the size of four directly adjoining parking spaces set side to side and front to rear. In actuality auto service facilities will often allow work on vehicles to spill outside the building, onto service drives and into parking areas. Outside work is a violation of the Zoning Ordinance, but the impacts are generally not too great with a larger freestanding facility which is well Page 4, Item ....A.... Meeting Date 8/28/96 separated from residential areas and other commercial uses. In this instance, with directly adjacent residential and adjoining commercial uses, there can be little tolerance for outside work. It is probably reasonable to believe that with such limited space inside the building, work could not be scheduled so that repairs would not occasionally occur outside the building. Tenant Compatibilitv The noise study showed that noise from the proposed service and repair operations measured in the adjacent tenant spaces was well within the limits that would comply with the city standard for residential uses (the City has no noise standards for the interior of commercial buildings). Again, however, it is difficult for us to believe that the noises and activities associated with auto repair would not be at least a potential disturbance to an adjacent retail or service commercial use such as a beauty salon or card shop. Whereas automotive repair facilities have previously been approved in commercial centers, they are typically located on freestanding pad sites, at the outer ends of buildings, or amongst primarily automotive-related businesses, rather than in the middle of a row of in-line shops in a commercial strip center. The auto repair uses that have been approved in this center, for instance, have been restricted to the spaces fronting on and with sole access off of Anita Street. CONCLUSION For the reasons noted, staff does not believe that the required findings for approval can be made and therefore has directed the application to the Planning Commission, As noted earlier, the use has already been relocated to the subject space, apparently due to a misunderstanding of the applicable regulations. The applicant recognizes and understands the potential problems and concerns of staff, but believes that the operation can be properly operated and controlled to minimize any potential conflicts.

PCC-97-1O RESOLUTION OF THE CITY OF CHULA VISTA PLANNING COMMISSION DENYING A CONDITIONAL USE PERMIT FOR A MINOR AUTOMOTIVE REPAIR FACILITY AT 1655 BROADWAY, SUITE 15, WITHIN THE C-C-P CENTRAL COMMERCIAL/PRECISE PLAN ZONE. WHEREAS, a duly verified conditional use permit application was filed with the City of Chula Vista Planning Department on July 30, 1996 by Jose Brijandez, and; WHEREAS, said application requests approval to for a minor automotive repair facility at 1655 Broadway, Suite 15, within the C-C-P Central Commercial/Precise Plan zone, and; WHEREAS, the Environmental Review Coordinator has determined that this proposal is exempt from environmental review under CEQA as a Class 5 exemption, and; WHEREAS, the Zoning Administrator did not believe that the required findings for approval could be made, and therefore referred the matter to the Planning Commission for review, and; WHEREAS, the Planning Director set the time and place for a hearing on said application and notice of said hearing, together with its purpose, was given by its publication in a newspaper of general circulation in the city and its mailing to property owners within 500 feet of the exterior boundaries of the property at least 10 days prior to the hearing, and; WHEREAS, the hearing was held at the time and place as advertised, namely August 28, 1996 at 7:00 p.m. in the Council Chambers, 276 Fourth Avenue, before the Planning Commission and said hearing was thereafter closed, and; WHEREAS, the Planning Commission considered all reports, evidence, and testimony presented at the public hearing with respect to the application. NOW, THEREFORE BE IT RESOLVED THAT THE PLANNING COMMISSION DOES hereby find, determine, resolve, and order as follows: I. Findings. 1. That the proposed use at the particular location is necessary or desirable to provide a service or facility which will contribute to the general well being of the neighborhood or the community. The proposed use at this particular location is not necessary or desirable to provide a service which will contribute to the general well being of the neighborhood because of the potential for negative noise and other impacts on surrounding uses and the fact that other automotive repair facilities exist nearby which provide similar services to the community. 2. That such use will not, under the circumstances of the particular case, be detrimental to the health, safety or general welfare of persons residing or working in the vicinity, or injurious to property or improvements in the vicinity. The proposed use has the potential to be detrimental to the general welfare of persons residing and working in the vicinity due to potential noise disturbances caused by automobile engines revving, loud tools, etc. on adjacent residents located 50 feet away, incompatibility of activities with adjoining retail and service commercial tenants due also to noise, and the potential for work to occur outside the building. 3. That the proposed use will comply with the regulations and conditions specified in the code for such use. There are no specific regulations or conditions specified in the code for this type of use. The use must be regulated by conditions imposed in a conditional use permit. In this case, given the proximity of the site to residential uses, it will be very difficult to impose and enforce conditions which are adequate to limit negative noise and other impacts. 4. That the granting of this conditional use will not adversely affect the general plan of the city or the adopted plan of any governmental agency. The granting or denial of this permit would not adversely affect the General Plan or the adopted plan of any governmental agency. II. Denial of Permit. In accordance with the findings above, the Plaffi1ing Commission hereby denies this request. III. A copy of this resolution shall be transmitted to the applicant.

The purpose of the survey was to determine if the proposed auto repair shop will comply with the City of Chula Vista Noise Ordinance requirements, and to evaluate the shop's compatibility with the adjacent businesses. The following is the results of the survey: Background Robertos Automotive Repair Shop has applied to the City of Chula Vista for a permit to operate an automotive repair shop. The shop will perform tune up, oil change and lubrication services between the hours of 9:00 a.m. and 7:00 p.m, Monday through Friday, and 10:00 a.m. and 5:00 p,m" Saturday and Sunday. Noise is generally defined as unwanted or annoying sound that is typically associated with human activity and which interferes with or disrupts normal activities, Although exposure to high noise levels has been demonstrated to cause hearing loss, the principal human response to environmental noise is annoyance. The response of individuals to similar noise events is diverse and influenced by the type of noise, the perceived importance of the noise and its appropriateness in the setting, the time of day and the type of activity during which the noise occurs, and the sensitivity of the individual. Airborne sound is a rapid fluctuation of air pressure above and below atmospheric pressure. Sound levels are usually measured and expressed in decibels (dB). Most of the sounds one hears in the environment do not consist of a single frequency, but rather a broad band of frequencies differing in sound level. The intensities of each frequency add to generate sound. This method, commonly used to quantify environmental sounds, consists of evaluating all of the frequencies of a sound according to a weighting system that reflects that human hearing is less sensitive at low frequencies and extremely high @ P'''''-''''''-'''''-,o,,,,, Mr. Steve Palma August 6, 1996 Page 2 frequencies than at the mid-range frequencies. This is called "A" weighting, and the decibel level measured is called the A-weighted sound level (dBA). In practice, the level of a noise source is conveniently measured using a sound level meter that includes a filter corresponding to the dBA curve. Although the A-weighted sound level may adequately indicate the level of environmental noise at any instant in time, community noise levels vary continuously. Most environmental noise includes a conglomeration of noise from distant sources that create a relatively steady background noise in which no particular source is identifiable. A single descriptor called the Leq (equivalent sound level) is used. Leq is the energy-mean A-weighted sound level during a measured time interval. It is the 'equivalent' constant sound level that would have to be produced by a given source to equal the fluctuating level measured. Noise sensitive receptors are land uses associated with indoor and/or outdoor activities that may be subject to stress and/or significant interference from noise. They often include residential dwellings, mobile homes, hotels, motels, hospitals, nursing homes, educational facilities and libraries. The closest noise sensitive receptor to the project site is a mobile home park located along the east property line. The property line is approximately 50 feet from the bay doors of the automotive repair shop. The City of Chula Vista noise ordinance (Chapter 19.68, Section 19.68.030) regulates noise from stationary sources across property lines. The maximum permitted property line sound level is based on an hourly average and is a function of the time of day and land use zone. The applicable sound level limit at the boundary of two zones is the more restrictive of the two zones. The automotive repair shop is located in a CC (commercial zone) and the mobile homes are located in an R-2 zone ( residential) (Steve Griffin, City of Chula Vista), Therefore, the maximum permissible hourly sound level is 60 dBA Leq between the hours of 7 :00 a.m. and 10:00 p.m. Apparatus and Procedure A Larson Davis Model 700 ANSI type 2 integrating sound level meter was used to quantify the ambient noise environment and to measure sound levels from various equipment. A one hour sound level measurement was taken between 8:00 a.m. and 9:00 a.m. at the property line prior to equipment measurement to quantify the ambient noise environment. The one hour sound level was 52 dBA Leq. The measurements were taken with the assumption that all automotive repair will take place within the building and that the bay door will be open. Sound levels were measured at approximately 5 feet from the equipment within the building, and at the property line adjacent to the mobile homes. The results of the measurements are summarized in Table I. Sound levels were also measured within the adjacent businesses (Units 14 and 16). The measurements were taken at approximately 5 feet from the adjoining waiL The results of the measurements are summarized in Table 2.

Maximum measured sound levels from the pneumatic wrench and revving engine were as high as 66 dBA. Although the sound levels from the pneumatic wrench and revving engine exceed 60 dBA at the property line, a noise source of 66 dBA would have to be used for 15 minutes per hour to exceed an hourly average of 60 dBA at the property line. Since noise from all of these sources would be intermittent, the hourly sound level at the property line would be expected to be less than 60 dBA and comply with the City Noise Ordinance. Mr. Steve Palma August 6,1996 Page 4 The measurements presented in Table 2 show that sound levels ranged between 42 and 45 dBA inside of Unit 14, and 41 and 46 dBA inside of Unit 16. The City of Chula Vista does not have a noise standard for the interior of commercial buildings. However for comparison, some communities such as the City of San Diego, require that the interior of new office buildings built near airports not exceed a maximum sound level of 50 dBA during an overflight. Noise levels from Robertos Automotive Repair Shop within Units 14 and 16 will be less than 50 dBA. This concludes the analysis, Please feel free to call me at 458-9044 if you have any questions.
