Proiect Setting The approximately L7-acre project site, located within the City of Chu]a Vista at 678 Third A venue, between I Street and J Street, contains an occupied muJti-story commercial office bui]ding and 166-space surface parking lot (see Exhibit A), Land uSeS surrounding the project site consist of the following: North: Salvation Anny Community Center South: Hemy's Market grocery store East: Medical offices West: Single-family residences B. Proiect Description The proposed project consists of the construction and operation of a three-level (ground level with two levels above) parking structure within the rear (western) portion of the project site to accommodate the parking needs of the existing on-site commercial office building (see Exhibit B), Construction of the proposed parking structure would increase the number of on- site parking spaces from 166 to 239, a net increase of 73 spaces. Ground level parking on- site, comprised of surface parking to the east of the parking structure and the ground level of the parking structure, would decrease from 166 to 138 spaces. Levels two and three of the parking structure would contain 51 and 50 spaces, respectively. Level three of the parking structure would be open with no roof or cover, and would be lighted with 12-foot high pole lights, The existing 6-foot high masomy wall along the northern, western, and southern property lines would remain. The existing surface parking lot extends to approximately three feet from the wall along the western property line; the proposed parking structure would be set back 10 feet from the western property line wall, with existing trees maintained and new trees planted within this 10-foot setback area, Existing Carrotwood trees along the entire perimeter of the project would be retained and six new 24-inch box AlIeppo Pine trees would 1 be planted in between the Carrotwood trees along the western property line. The proposed parking structure requires the approval of a Design Review Permit by the City of Chula Vista Design Review Committee, C. Compliance with Zoning and Plans The project site is zoned C-O (Administrative and Professional Office Zone) under the City's Municipal Code and is designated "Commercial - Professional & Administrative" under the City's adopted General Plan, The proposed parking structure would be compatible with the existing zoning and land use designation of the site. D, Public Comments On Novcmber 22, 2002, a Notice of Initial Study was circulated to property owners within a SOO-foot radius of the project site. The public comment period closed on December 6, 2002. No comment letters were received. K Identification of Environmental Effects An Initial Study conducted by the City of Chula Vista (including an attached Environmental Checklist form) determined that the proposed project will not have a significant environmental effect, and the preparation of an Environmental Impact Report will not be required, This Negative Declaration has been prepared in accordance with Section 15070 of the State CEQA Guidelines. . Noise Single-family residential properties, separated from the project site by an existing six-foot high masonry wall along the western property line, are situated immediately west of the project site. Commercial properties are situated to the north and south and medical offices are situated to the east of the project site across Third Avenue, In order to assess the potential noise impacts of the proposed parking structure, a noise technical report was conducted by RECON, the results of which are contained in their report dated December 12, 2002, and are summarized below. Noise Standards The noise technical report assessed the proposal with respect the regulations contained in Chapter 19.68, Performance Standards and Noise Control, of the Chula Vista Municipal Code (noise ordinance). Pursuant to the noise ordinance, no person shall operate, or cause to be operated, any source of sound at any location within the city or allow the creation of any noise on property owned, leased, occupied or otherwise controlled by such person which exceeds the following equivalent sound level (Leq) for anyone-hour period, expressed in A- weighted decibels, dB(A), at or beyond the property boundary: 2 All Residential (Except Multiple Dwelling) Weekdays: 10:00 p.m, to 7:00 a,m. Weekdays: 7:00 a.m. to 10:00 p,m, Weekends: 10:00 p,m. to 8:00 a-ID. Weekends: 8:00 a.m. to 10:00 p,m. 45 dB(A) Leq (one-hour) 55 dB(A) Leq (one-hour) Commercial Weekdays: 10:00 p.m. to 7:00 a.m, Weekdays: 7:00 a,m. to 10:00 p.m. Weekends: 10:00 p.m, to 8:00 a.m, Weekends: 8:00 a.m, to 10:00 p.m. 60 dB(A) Leq (one-hour) 65 dB (A) Leq (one-hour) Noise Measurements The official business hours of the office bui1ding are from 7:00 a.m. to 6:00 p.m. Monday through Friday and 7:00 a,m. to 5:00 p,m. on Saturday, Although employee access to the parking lot and office building is not limited to these hours, based on current usage and observations, nighttime activity (10:00 p.m, to 7:00 a.m.) and weekend activity is atypical. Noise measurements were taken on the project site on two separate days. Measurements I and 2 were taken on Monday, October 21,2002, consisting of two 20-minute measurements taken between 10: 15 a,m. and II :05 a.m, Measurement 3, consisting of a three-hour measurement, was taken on Thursday, November 21, 2002, between 6:00 a.m, and 9:00 a.m. All measurements were taken along the western perimeter of the project site adjacent to the single-family residences to the west; measurements 1 and 3 were taken directly west of the office building and measurement 2 was taken to the northwest of the building, The location of measurement I was shielded from Third A venue traffic noise by the office building; the overall noise level for measurement I was 53,1 dB(A) Leq for the 20-minute measurement period. The location of measurement 2 had a small, but direct line of sight to traffic on Third Avenue; the overall noise level for measurement 2 was 52,2 dB(A) Leq for the 20-minute measurement period. Traffic in the on-site parking lot was counted during these noise measurements and was classified as to the area of the lot accessed by each car; the time each traffic activity occurred was also noted, In the absence of parking lot activities and other single events, such as sirens and aircraft flyovers, the background noise level without parking lot activity was estimated a graph of the noise measurement data to be 47 dB(A) Lcq. This background noise was subtracted from the overall total measured noise; the resulting noise was assumed to be the noise level produced by parking lot activities alone. The result was a noise level of 5 L9 dB(A) Leq at 45 feet from the source. This reference noise level corresponds to an activity volume of 33 vehicles over one hour and a per-vehicle noise level of35.8 dB (A) at 50 feet from the source. The location of measurement 3 was shielded from Third A venue traffic noise by the office building; the overall hourly noise levels for measurement 3 were 54.4 dB (A) Leq between 6:00 a.m. and 7:00 a,m" 55.6 dB(A) Leq between 7:00 a.m. and 8:00 a.m., and 53.1 dB (A) Leq between 8:00 a.m. and 9:00 a.m. Traffic in the on-site parking lot was counted during the noise measurements and was classified as to the area of the lot accessed by each car; the time each traffic activity occurred was also noted, During the heaviest-use hour of 8:00 a.m. 3 to 9:00 a,m., 67 vehicles accessed the rear parking area, 8 parked in the area to the north of the building, and 23 parked in the area to the south of the building. These traffic counts correspond to 23 percent, 68 percent, and 69 percent of the spaces to the north, south, and rear of the building, respectively. This measured hour is assumed to represent the busiest, or worst-case, daytime hour for parking lot activity. Although the total noise measured was loudest between 7:00 a.m, and 8:00 a.m., the heaviest use of the parking lot was between 8:00 a.m. and 9:00 a,m. The higher average noise levels in the earlier hours can be attributed to background noise from the roadways and other sources. Therefore, the data from 8:00 a.m, to 9:00 a.m. was used to establish a reference noise level for this noise measurement The average background noise level without parking lot activity was estimated from a graph of the noise measurement data to be 50.4 dB(A) Leg, This value was subtracted from the measured noise level, which resulted in a noise level of 50.0 dB(A) Leg at 52.5 feet from the sourcc due to parking lot activity, This reference noise level corresponds to an activity volume of 67 vehicles over one hour, which corresponds to a per-vehicle noise level of 32,2 dB(A) at 50 feet from the source. Projected Existing Noise Levels In order to obtain a reference noise level for use in noise projection calculations, the per- vehicle noise levels obtained from the measurements were log-averaged, resulting in a reference noise level of 33.7 dB(A) per vehicle at 50 feet from the source. The reference noise level was adjusted for distance and the number of vehicles accessing the site in order to calculate the existing noise level during the worst-case daytime hour at the western property boundary on the residential side of the existing six-foot high masonry wall. Taking into account noise attenuation associated with the wall, parking lot activity noise was calculated to be 49.6 dB(A) Leg (one-hour) on the residential side of the wall. The existing worst-case daytime noise level at the commercial project boundaries, on the adjacent properties' side of the wall, due to parking lot activity noise was calculated to be 50.8 dB (A) Leg (one-hour) to the north and south of the project site, Field visits were conducted to assess weekend and nighttime usage of the parking lot At 3:45 p.m, on Saturday, November 9, 2002, eight cars were parked in the lot At 11:10 a.m. on Sunday, November 17, 2002, six cars were parking in the lot At 9:07 p.m. on Thursday, November 21, 2002, three cars were parked in the lot Based on these observations, it is assumcd that the busiest nighttime-use hour is weekdays from 6:00 a.m. to 7:00 a.m, The existing noise level for the nighttime hour at the residential and commercial project boundaries (between 6:00 a.m. and 7:00 a.m.) was calculated to be 41.5 and 423 dB(A) Leg (one-hour) due to parking lot activity, respectively. Future Acoustical Environment and Impacts (Residential - Daytime) To calculate the future worst-case hourly noise level at the residential-use project boundary due to parking lot activity, the reference noise level of33.7 dB (A) per vehicle at 50 feet from the source was adjusted to reflect future conditions with the proposed parking structure. Adjustments to this reference level and resulting noise levels were calculated for each section of the parking lot (side section-north, side section-south, rear ground level, rear second level, and rear third level). The future hourly vehicle activity volume for each section was assumed to be 69 percent of the parking spaces in each section, which was the highest level of hourly 4 activity observed among the three existing portions of the parking lot. It was assumed that half of the traffic accessing the parking structure would pass through each side lot and, because the ground and second levels of the parking structure will provide access to the third level, adjustments were made for the volume of vehicles passing through the ground and second levels, Five decibels was subtracted ITom the rear and side ground level parking area noise levels to account for the reduction provided by the six-foot high masonry wall on the western property line, Reductions to the noise levels on the second and third levels of the parking structure were made to account for the three-foot high concrete panels proposed along the western perimeter of the parking decks. The resulting future worst-case noise level at the residential-use project boundary on the residential side of the wall due to parking lot activity noise was calculated to be 54.2 dB (A) Leg (one-hour), which would not exceed the City's daytime hourly noise standard. Future Acoustical Environment and Impacts (Residential - Nighttime) By using the reference noise level of 33.7 dB(A) per vehicle and the applicable distance and wall noise level adjustments, the maximum number of cars that could access the parking lot per hour, distributed evenly throughout the lot, without exceeding the residential nighttime noise limit, was found to be 40. Furthermore, under a worst-case scenario assuming all of the cars accessing the site were to park in the upper levels of the parking structure, the maximum number of cars that could access the parking lot per hour without exceeding the noise limit was found to be 23. Since no typical nighttime activity is expected, and occasional use would be low, this number of cars per nighttime hour is not expected to be exceeded; therefore, noise levels are expected to comply with City standards, Future Acoustical Environment and Impacts (Commercial) The future worst-case daytime noise level at the northern and southern commercial-use project boundaries due to parking lot activity noise was calculated to be 53,6 and 53.7 dB (A) Leg (one-hour) on the adjacent properties' side of the wall, respectively, Use of the parking lot during nighttime hours is anticipated to be inITeguent, but would not be prohibited, By using the reference noise level of33.7 dB(A) per vehicle and the applicable distance and wall noise level adjustments, the maximum number of cars that could access the parking lot per hour, distributed evenly throughout the lot, without exceeding the commercial nighttime noise limit, was found to be 850, which is much less even than the worst-case daytime level of activity and is greater than the proposed number of parking spaces, Construction Noise Noise associated with earthwork and construction would result In short-term noise generation, Although construction activities arc exempt from the exterior noise standards of the Chula Vista Municipal Code described above, the Municipal Code prohibits construction Monday through Friday from 10:00 p,m. to 7:00 a.m. and from 10:00 p.m. to 8:00 a.m. on Saturdays and Sundays. Compliance with the allowable construction activity periods of the Municipal Code would ensure that construction noise would not cause a significant nuisance noise impact to residents and businesses in the immediate vicinity of the project site. 5 - Aesthetics The western façade of the proposed 25-foot high parking structure would be set back ten feet from the western property line of the project site, which is separated from single-family residential properties to the west by an existing six-foot high masonry wall (see Exhibit B). Therefore, a portion of the proposed parking structure would be visible from the rear portion of single-family residential properties to the west. Existing mature Carrotwood trees are situated on the project site along the masonry wall that separates the project site from the adjacent single-family residential properties, To achieve a greater degree of vegetative screening of the proposed parking structure from the west, six new 24-inch box Alleppo Pine trees would be planted in between the existing Carrotwood trees along the western property line (see Exhibit C). Three-foot high concrete walls are proposed along the western façade of the second and third levels of the parking structure, which, in addition to attenuating vehicle noise, would aid in screening vehicles parked along the western perimeter of these levels. The proposed parking structure is an allowable accessory structure with the C-O zone in which it is proposed to be constructed, The existing six-foot high masonry wall, the existing and proposed new trees along the western property line, and the proposed 10-foot setback between the wall and the western façade of the parking structure would screen and minimize the intrusiveness of the proposed 25-foot high parking structure. Although the proposed parking structure would result in a change to the viewshed of the adjacent residential properties, given the zoning of the project site, the location of the site on an established, intensively developed commercial corridor, and the moderate height and bulk of the proposed structure, the impact of this change would not rise to a level of significance under the California Environmental Quality Act as implemented by the City ofChula Vista. The proposal includes downward-facing, non-spill exterior lighting on 12-foot high poles on the upper level of the parking structure. Pursuant to Sections 19,66.060 and 19.66.100 of the Chula Vista Municipal Code, no direct or sky-reflected glare shall be permitted from lighting so as to be visible at the lot line of an establishment or use. The proposed lighting would be required to comply with the glare regulations of the Chula Vista Municipal Code and, therefore, would not result in a significant glare impact. F.

Comments: a) A geotechnical investigation of the project site was conducted by Geocon, Incorporated, the results of which are contained in their report entitled "Geotechnical Investigation - Corporate Plaza Parking Structure, 678 Third Avenue, Chula Vista, California," dated October II, 2002, The purpose of the investigation was to observe and sample prevailing soil conditions underlying the site and to provide recommendations relative to geotechnical aspects of the proposed development. The scope of the investigation included a site reconnaissance, field investigation, laboratory testing, and engineering analyses. The field investigation was perfonned on September 14, 2002, and consisted of a site reconnaissance and drilling three exploratory small-diameter borings, which were drilled to depths of 40 feet. The soil conditions encountered in the borings were visually examined, classified, and logged. Laboratory tests were perfonned on selected soil samples obtained from the borings to detennine pertinent physical properties for engineering analyses, The soils encountered during the field investigation consisted of undocumented fill and fonnational soils of the Bay Point Fonnation. Groundwater was not encountered during the field investigation and is not anticipated to significantly impact the proposed development. A review ofthe geologic literature indicates that there are no known active or potentially active faults at the site or in the immediate vicinity and no evidence of faulting was encountered in the subsurface exploration program, The Rose Canyon Fault, located approximately 6,5 miles northwest of the site, is the closest known active fault. Earthquakes that might occur on the Rose Canyon, Coronado Bank, Newport- Inglewood-Offshore, Elsinore, and other faults within the southern California/northern Baja California area are potential generators of significant ground motion at the site, The Rose Canyon Fault, postulated as having the potential to generate a maximum earthquake of magnitude 6.9, is the most significant potential source of ground motion at the site due to its proximity. The site could be subjected to moderate to severe ground shaking in the event of an earthquake on any of the faults within the region. However, the seismic risk at the site is not considered significantly different from that of surrounding developments, No landslides were encountered during the site investigation and none are known to exist on the property or at a location that would impact the proposed development. Due to the high density of the underlying soils and the lack of penn anent near-surface groundwater, the potential for Jiquefaction occurring at the site is considercd "very low." Based upon the results of the geotechnical investigation, the proposed project is considered feasible from a geotechnical engineering point of view provided the structure is designed in accordance with the applicable building regulations and provided the engineering recommendations contained in the report are followed. Page - ) b) See IILa, above, Proper engineering design would ensure that no such soils-related impacts would result. c) The proposed site has been previously graded; further changes in topography to accommodate the proposal would be nominal. d) No unique geologic or physical features exist within the proposed development area of the site. e) Appropriate erosion control measures will be identified in conjunction with the preparation of final construction plans and will be implemented during construction, All portions of the development area disturbed during construction will either be developed or appropriately landscaped in accordance with final construction plans for the project. Therefore, no significant increase in soils erosion would result. t) See IILe. above. No significant erosion or siltation impacts are anticipated to result from the proposed development. g) See IILa. above. PotentiaUy Potentially Significant Less than IV. WATER.

Page - 4 Comments: a) The proposed construction of a parking structure on the entirely developed project site would not result in a change in the on-site absorption rate. The site presently drains via sheet flow towards Third A venue, where a stonn drain inlet exists in the street approximately 250 feet to the south, The submittal ofa drainage study would be required prior to the issuance of construction pennits to demonstrate that existing in!Tastructure would be adequate to serve the project; no significant impacts to the City's stonn drainage system are anticipated to result from the project. b) The project site is beyond the limits of the 500-year floodplain and is not in proximity to any bay or oeean; therefore, no exposure of people or property to water related hazards would result from the proposed development. c) Through construction pennit conditions of approval, the proposed project will be required to implement construction and post-construction Best Management Practices (BMPs), where applicable, in accordance with the City ofChula Vista Stonn Water Management Standards Requirements Manual in order to prevent pollution of downstream water bodies, d) Based on the size and nature of the proposed development, and the location of the project site relative to natural water bodies, the projeet would not result in any changes in the amount of surface water in any water body, in eurrents, or the course of direction of water movements, in either marine or fresh waters, e) See lV,d. above, f) According to the geotechnical investigation prepared for the projeet (Geocon, Incorporated, 2002), groundwater was not encountered in the exploratory borings. No changes in the quantity of groundwater, or other impacts to groundwater, are expected to result from the proposed development of the site. g) See IV.f. above, h) See IV.f. above, i) See IV.b, above.

Comments: a) Based on the limited amount of site !,'Tading necessary to accommodate the proposed development and because the proposal would not result in an increase in traffic generated by the existing on-site office building, the proposal would not result in the violation of any air quality standard or contribute to an existing or projected air quality violation. b) The operation of the proposed parking structure is not anticipated to result in an increase in the exposure of sensitive receptors to pollutants. To the contrary, the provision of ample parking to meet the present needs of existing office building tenants is anticipated to reduce the time spent by employees and clients searching for on- and off-site parking, thereby potentially reducing automobile emissions generated in the vicinity of the project site, c) The proposed parking structure is not anticipated to significantly alter air movement, moisture, or temperature, or cause any change in climate. d) Neither development nor operation of the proposed parking structure is anticipated to create any objectionable odors, e) Because the proposal would not result in an increase in traffic generation, the proposal would not result in an increase in non-stationary sources of air emissions or the deterioration of ambient air quality. No stationary sources of air emissions would be associated with the proposed parking structure. Potentially VI. TRANSPORTATION/CIRCULATION.
