The public comment period closed on May 20, 2002, Three comment letters were received. E. Identification of Environmental Effects An Initial Study conducted by the City of Chula Vista (including an attached Environmental Checklist form) determined that the proposed proj ect will not have a significant environmental effect, and the preparation of an Environmental Impact Report will not be required. This Mitigated Negative Declaration has been prepared in accordance with Section 15070 of the State CEQA Guidelines, Water Construction activities and operational activities associated with urban development generate various pollutants that enter municipal storm drainage systems through both storm water and non-storm water runoff. Transported by runoff, these pollutants eventually feed into and pollute natural water bodies. The City of Chula Vista is a Municipal Copermittee under the February 21, 2001, California Regional Water Quality Control Board, San Diego Region Order No, 2001-01, NPDES No. CASOl08758 ("Order"), which regulates the treatment of urban runoff prior to its discharge into municipal storm drainage systems. Appropriate erosion control measures will be required during construction to prevent the discharge of sediment into the storm drainage system. In addition, the proposed development is required to implement permanent, post-construction best management practices (BMPs), consisting of non-structural (i.e" maintenance practices) and/or structural (e,g., biofiltration, mechanical filtration devices) methods. Compliance with the Order through the implementation of appropriate BMPs, as specified below in Section F, would mitigate this potentially significant impact to below a level of significance, Noise Single-family residential development is situated to the east of the project site; the nearest residential property boundary is approximately 185 feet ftom the edge of the proposed skate park, No other sensitive receptors are located within the immediate vicinity of the site. In order to assess the potential noise impacts of the proposed skate park to the residences to the east, an acoustical analysis was conducted by Pacific Noise Control, the results of which are contained in their report dated July 18, 2002. 2 The acoustical analysis assessed the proposal with respect the regulations contained in Chapter 19.68, Perfonnance 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 decibels (dB), at or beyond the boundary of single-family residential properties: 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.ill- Weekends: 8:00 a.m. to 10:00 p.m. 45 dB Leq (one-hour) 55 dB Leq (one-hour) A noise measurement was conducted bctween II :35 a.m, and 11 :55 a,m. on May 29, 2002, at the residential development closest to the project site in order to detennine the typical daytime ambient noise leveL The measured noise level was 51 decibels, which was primarily attributable to vehicles traveling on Interstate 805, Traffic noise from East Palomar Street and Oleander Avenue was also audible and three cars traveled along Sipes Circle during the noise measurement period. During the peak traffic periods, the hourly average noise level is typically approximately two to three decibels greater than the late morning hours. To detennine the approximate noise levels that would be generated at the skate park and to detennine potential noise impacts, eight noise measurements were conducted at several existing skate parks with similar characteristics as the proposed facility, including the Carlsbad Safety Center Skate Park in Carlsbad and the Civic Center Skate Park in Vista. Ultimately, the noise level data from the Carlsbad facility was used because the proposed skate area is about the same size and because this facility had the greatest number of skaters during the noise measurements, The peak noise levels generated during the noise measurements were typically associated with skaters jumping onto skate curbs and down into the skate bowls; these peak noise levels would range up to approximately 65 dB at the property lines of the nearest residences to the project site. Also, people talking and shouting generated noise at the skate parks, The maximum number of skaters observed during the noise measurements at the Carlsbad facility was 28 with a measured average hourly equivalent noise level of 53 dB at a distance of 50 feet from the skate park. The measured noise level was increased to account for the noise level associated with the capacity of the proposed skate park of up to 60 skaters. In tenns of decibels, the approximate doubling of the number of skaters is equivalent to an increase of approximately three dB- This increase assumes that the additional skaters would generate a noise level that is proportionally equal to the measured noise level of 28 skaters. Thus, based on the noise measurements, and after adjusting for a capacity of 60 skaters, the typical skateboard activities would generate a one-hour average noise level of up to approximately 56 dB at a distance of 50 feet from the edge of the skate park. The property boundary of the closest residences to the proposed skate park are situated along Sipes Circle, approximately 185 feet to the east. At full capacity, the one-hour average noise level would range up to approximately 48 dB at the closest residences. This noise level would comply with the City noise ordinance one-hour average noise level limit of 55 dB between the hours of 7:00 a.m. to 10:00 p,m. on weekdays and 8:00 aÆ, to 10:00 p,m. on 3 weekends; however, this noise level would not be in compliance with the noise ordinance one-hour average limit of 45 dB beyond these hours. Therefore, in order to avoid a potential violation of the noise ordinance, which is considered a significant noise impact, the skate park will be closed between the hours of 10:00 p.m. and 7:00 a.m. on weekdays and 10:00 p.m. and 8:00 a.m. on weekends, as specified below in Section F. Aesthetics (Glare) The proposal includes floodlights on 50-foot poles at the four corners of the skate area to enable the utilization of the facility after dark Pursuant to Sections 19.66,060 and 19.66.100 of the Chula Vista Municipal Code, no direct or sky-reflected glare shall be pell11itted rrom floodlights so as to be visible at the lot line of an establishment or use. The only neighboring land use that would potentially be affected by glare associated with the proposed lighting is the residential development east of the site. Immediately to the north of the site are lighted ballfields, which are also within Greg Rogers Community Park. Implementation of the mitigation measure contained below in Section F would ensure that the proposed lighting complies with the aforementioned glare regulations of the Chula Vista Municipal Code and, therefore, would not result in a significant glare impact. Air Oualitv Potentially significant, short -tell11 air quality impacts would occur during construction. Construction emissions would come rrom heavy equipment exhaust and fugitive dust generated by excavation and grading operations, The implementation of the mitigation measures specified below in Section F would reduce this potentially significant impact to below a level of significance, F, Mitigation Necessary to Avoid Significant Impacts Water L Prior to the issuance of any grading pell11it, the City Engineer shall verify that the final grading plans and specifications comply with the provisions of California Regional Water Quality Control Board, San Diego Region Order No, 2001-01 with respect to construction-related water quality best management practices. 2, Prior to the approval of any improvement plans or the issuance of any building pell11it, the City Engineer shall verify that the final plans and specifications comply with the provisions of Cali fomi a Regional Water Quality Control Board, San Diego Region Order No, 2001-01 with respect to penn anent, post-construction water quality best management practices (BMPs). If one or more of the approved post-construction BMPs is non- structural, then a post-construction BMP plan shall be prepared to the satisfaction of the City Engineer prior to the commencement of construction; compliance with said plan shall become a pell11anent requirement of the Mitigation Monitoring and Reporting Program. 4 Noise 3. To ensure compliance with the exterior noise regulations contained in Section 19.68,030 of the Chu]a Vista Municipal Code, the skate park shall be closed between the hours of ]0:00 p.m, and 7:00 a,m. on weekdays and between 10:00 p.m. and 8:00 a.m. on weekends. Aesthetics (Glare) 4, To ensure that the project complies with the glare regulations contained in Sections ]9.66,060 and ]9.66.100 of the Chu]a Vista Municipal Code, exterior lighting shall be adequately directed and shielded, as necessary. Prior to the final approval of the construction documents, a lighting analysis demonstrating that the proposed exterior lighting plan complies with the glare regulations of the Municipal Code shall be prepared to the satisfaction of the Environmental Review Coordinator. Following the installation of the exterior lighting and prior to final acceptance of the installation, compliance with the glare regulations of the Municipal Code shall be verified through a nighttime field inspection to the satisfaction of the Director ofP]anning and Building. Air Qualitv 5, Dust reducing measures shall include watering of graded surfaces in accordance with the most stringent County of San Diego Air Pollution Control District and California Air Resources Board rules and regulations and the restriction of all construction vehicles and cquipment to travel along established roadways at specified speeds. 6. During construction, stockpiled materials that can potentially become airborne shall be covered or watered in accordance with the most stringent County of San Diego Air Pollution Control District and California Air Resources Board rules and regulations. 7, During construction, dirt and debris shall be washed down or swept up as soon as practicable to reduce the resuspension of particulate matter caused by vehicle movement over such material. Approach routes to the construction area shall be cleaned daily of construction-related dirt and debris. 8. In accordance with California Vehicle Code Section 23] ] 4, vehicles transporting loads of aggregate materials must cover/tarp the material, or if not covered, the material must be no nearer than six inches from the upper edge of the container area where the material contacts the sides, front, and back of the cargo container area, and the load shall not extend, at its peak, above any part of the upper edge of the cargo container area, 9. Construction equipment shall be tuned prior to the start of construction and shall be maintained in proper working order in order to minimize air pollutant emissions; use of low pollutant-emitting construction equipment, including electrical-powered equipment, shall be used as practical. 10. Soil disturbance and travel on unpaved surfaces shall be suspended when wind speeds exceed 25 miles per hour. 5 G. Consultation 1.

Comments: a) In order to detennine and evaluate the surface and subsurface conditions on the subject site and to present recommendations for foundation systems and grading requirements as they pertain to the proposal, a geotechnical engineering study was conducted by Allwest Geoscience, Inc., the results of which are contained in their report entitled "Geotechnical Engineering Study for the Chula Vista Skate Park, Boys and Girls Club," dated March 20, 2002. The subject site is a roughly rectangular cut-fill graded pad currently used primarily as a playground. The site is relatively level with a fall of approximately I to 2 percent toward a paved drain at the southeast corner and the parking lot on the southwest corner. The soil and ground water conditions beneath the site were explored by drilling six borings to depths of 5 to 30 feet below the existing grade. Disturbed and undisturbed samples of the soils encountered were obtained at frequent intervals in the borings and were subjected to laboratory testing. The earth materials underlying the site consist of man-made fill and sandstone bedrock belonging to the San Diego fonnation. A thin veneer of reworked natural soil or fill overlies the northwesterly portion of the playground area, and deepens to 22 feet or more in the southeasterly portion of the area. Groundwater was not encountered in the borings; further, none is expected that would affect the perfonnance of the site. No active or potentially active faults are known to transect the site. The subject site is not within the limits of the currently established Earthquake Fault Zone as defined by the Alquist-Priolo Earthquake Fault Zoning Act and does not require a special fault study. Although the site could be subjected to strong ground shaking in the event of an earthquake, this hazard is common in southern California and the effects of ground shaking will be addressed through compliance with the applicable building codes and proper structural engineering design. Because of the dense nature ofthe underlying bedrock, and the lack of groundwater in the underlying fill soil, the potential for liquefaction at the site is considered low to very low. Based upon the results of the geotechnical engineering study, the proposed project is considered feasible from a geotechnical engineering point of view provided the engineering recommendations of the report are followed, b) 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. Page - 3 e) Appropriate erosion control measures will be identified in conjunction with the preparation of final grading 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 the landscaping and improvement plans for the project. Therefore, no significant increase in soils erosion would result. t) As described above (IlL e.), no significant erosion or siltation impacts are anticipated to result from the proposed development. g) See IILa. above, Potentially Potentially Significant Less than IV.

Comments: a) The proposed grading and development of the previously graded, largely unimproved site would result in changes in absorption rates, drainage patterns, and the rate and amount of surface runoff. A drainage study will be prepared in conjunction with the preparation of final grading and improvement plans and properly designed drainage facilities will be installed at the time of site development. Surface runoffwill be Page - 4 collected on-site and discharged into the existing City stonn drainage system; no significant impacts to the City's stonn drainage system are anticipated to result from the proposed development b) The project site is beyond the limits of the 500-year floodplain and is not in proximity to any bay or ocean; therefore, no exposure of people or property to water related hazards would result from the proposed development c) See Mitigated Negative Declaration, Section E. d) The proposed development of the site would result in the creation of impervious surfaces on the site which, in turn, would result in an increase in surface runoff. However, the increase in runoff that would result from the project would be nominal in comparison to the volume of water in water bodies downstream of the site, e) Surface runoff will be collected on-site and discharged into the existing City stonn drainage system; based on the planned stonn water drainage methodology, the size of the proposed development, and the location of the project site relative to natural water bodies, the project would not result in any changes in currents, or the course of direction of water movements, in either marine or fresh waters, £) According to the geotechnical engineering study prepared for the project (AlIwest Geoscience, Inc,), 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, No alterations to the course or flow of flood waters downstream of the site are expected to result from the proposed development of the site, j) The project site is within the service area of the Otay Water District The operation of the proposed public library facility is not anticipated to result in a significant net increase in the consumption of water otherwise available for public consumption.

Comments: a) Based on the limited amount of site grading that will be necessary to accommodate the proposed development and the projected amount of project-generated traffic, 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 skate park would not generate a significant amount of pollutants and skate park patrons and employees would not be exposed to an atypical level of urban pollutants. See Section E. of the Mitigated Negative Declaration regarding significant, short-term construction-related air quality impacts. c) The proposed development and operation of an outdoor skate park on the project site would not alter air movement, moisture, or temperature, or cause any change in climate. d) Neither development nor operation of the proposed skate park is anticipated to create any objectionable odors, e) Based on the projected amount of project-generated traffic, the proposal would not result in a substantial increase in stationary sources of air emissions or the deterioration of ambient air quality. Stationary sources of air emissions generated by the proposed library facility would be nominal. PotentiaUy VI. TRANSPORT A TION/CIRCULA TION.

(An equivalent of 2400 or more average daily vehicle trips or 200 or more peak-hour vehicle trips,) Page - 6 Comments: a) No standard trip generation rates exist for skate parks; therefore, for the purposes of conducting a worst-case analysis of the project's traffic impacts, the trip generation rate for a more intensive recreational use (bowling alley) was utilized, In addition to bowling alleys being a more intensive use on a per acre basis, it is anticipated that a significant number of skate park patrons will either bicycle or walk to the facility. Based on the bowling alley trip generation rate of300 average daily trips (ADT) per acre, the proposed skate park would generate 390 ADT. The primary access roads serving the project site, East Palomar Street, Oleander A venue, and East Naples Street, currently operate at level of service (LOS) A; with project-added traffic, these streets are projected to continue to operate at LOS A. Therefore, even under a worst-case trip generation scenario, the project is not anticipated to result in any traffic congestion, b) Vehicular access to the project site would be via the existing Boys and Girls Club driveway on Oleander A venue. No traffic safety hazards are anticipated to result trom the project. c) The proposed site plan provides for adequate emergency access from Oleander Avenue, d) The existing Boys and Girls Club parking lot is considered adequate for the proposed skate park facility, particularly since most skate park users are anticipated to either be dropped off or to travel to the facility by bicycle or on foot. e) The proposal would not result in any hazards or barriers for pedestrians or bicyclists. f) No conflicts with adopted policies supporting alternative transportation would result. Bicycle racks would be provided on-site, g) No rail, navigable waters, or aircraft facilities exist in the vicinity of the project site; therefore, the proposed development of a skate park on the project site would not result in any rail, waterborne or air traffic impacts, h) The proposed skate park is projected to generate much less than 2,400 average daily trips and 200 daily peak-hour trips; therefore, the project is not considered a "large project" under the Congestion Management Program.
