PEDESTRIAN EASEMENT Pedestrian easements over the sidewalk areas (portion on private property) and through the interior pedestrian paths and plazas shall be prepared by the developer, approved by the City Attorney and recorded against the subject property prior to issuance of building permits. MITIGATIONS (CEQA) The project shall provide the following mitigations to reduce project impacts to an insignificant level per the Mitigated Negative Declaration: 28. AIR QUALITY Impact: Construction of the proposed project could result in significant short-term air quality impacts associated with dust generation. Mitigation: The BAAQMD has prepared a list of feasible construction dust control measures that are expected to reduce construction impacts to a less-than-significant level. The following mitigation would be implemented during all phases of construction on the project site: ■ Use dust-proof chute for loading construction debris onto trucks. ■ Water all active construction areas at lest twice daily or as often as needed to control dust emissions. ■ Cover all truck hauling soil, sand, and other loose materials or ensure that all trucks hauling such materials maintain at least two feet of freeboard. � ■ Pave, apply water three times daily or as often as necessary to control dust, or apply non-toxic soil stabilizers on all unpaved access roads, parking areas and staging areas at construction areas. ■ Sweep daily or as often as needed with water sweepers all paved access roads, parking areas and staging areas at construction sites to control dust. ■ Sweep public streets daily or as often as needed to keep streets free of visible soil material. ■ Hydroseed or apply non-toxic soil stabilizers to inactive construction areas. ■ Enclose, cover, water twice daily or apply non-toxic soil binders to exposed stockpiles (dirt, sand, etc.). ■ Limit vehicle traffic speeds on unpaved roads to 15 mph: ■ Install sandbags or other erosion control measures to prevent silt runoff onto public roadways. ■ Replant vegetation in disturbed areas as quickly as possible. 29. BIOLOGICAL RESOURCES Measure: Preconstruction surveys for nesting raptors shall be conducted by a qualified ornithologist to ensure that no raptor nests will be disturbed during project construction. This survey will be conducted no more than 14 days prior to initiaiion of demolition/construction activities during the early part of the breeding season (January through April) and no more than 30 days prior to demolition/construction activities 8 Resolution No. 6183 U-2002-06 Apri128,2003 Page 9 during the late part of the breeding season (May through August). If active nests are found, the ornithologist, in consultation with the CDFG, will determine the extent of a construction-free buffer zone to be established around the nest. Measure: Heritage and Specimen Tree Protection ■ For trees to be retained, chain link fencing and other root protection shall be installed around the dripline of the tree prior to any project site work. ■ No parking or vehicle traffic shall be allowed under root zones, unless using buffers approved by the Project Arborist. ■ No trenching within the critical root zone area would be allowed. If trenching is needed in the vicinity of a Heritage or Specimen tree, the Project Arborist shall be consulted before any trenching or root cutting beneath the dripline of the tree. ■ Wood chip mulch shall be evenly spread inside the tree projection fence to a four-inch depth. ■ The Project Arborist shall oversee all tree relocation and maintenance activities. The movement of as large of root ball as possible, at least 20 feet in diameter, will be required. ■ All trees retained shall be deep root fertilized (using a solution of 22-14-14) after the trees have been removed. Fertilizing shall be repeated annually for five years injected into root zone by hydraulic spray equipment. 30. HAZARDS AND HAZARDOUS SUBSTANCES Impact: Ongoing Operations. Because the site allows medical office uses there is a potential that the current and future users could use, store, or handle limited quantities of hazardous materials in its operations. Of particular concern would be if a new use introduced hazardous materials in proximity to the residential uses proposed as part of � the project. Impact: Demolition Activities. Buildings on the project site were found to contain asbestos and lead. Other materials including chlorofluorocarbons, mercury, PCBs, fuel, oils, and other chemicals may also be present on the project site. Removal/relocation and transportation of hazardous materials at the site could result in an accidental release that could potentially pose health risks to workers, the public, and the environment. As part of the demolition, asbestos and lead paint contamination would be removed and disposed of in accordance with a�plicable re�ulations. This will include, conducting samplin� of suspect Asbestos Containing Materials (ACMs) to fully characterize the materials in accordance with BAAQMD requirements prior to demolition, retaining a Certified Asbestos Consultant or Site Surveillance Technician for on-site construction supervision of the asbestos abatement pro�ram to ensure utilization of proper work practices, and ensuring that lead paint only be abated by workers trained bX the California Department of Health Services. State re�ulations require that air monitoring be performed durin�and following renovation or demolition activities at sites containing lead-based paint or asbestos. Appropriate modifications to renovation/demolition activities would be required if airborne lead levels exceed the current Federal OSHA action levels. 9 Resolution No. 6183 U-2002-06 Apri128, 2003 Page 10 Mitigation: Conformance with the following Federal, State and local laws would reduce the potential for hazardous materials impacts from the potential use of hazardous materials on the site: ■ The Accidental Release Prevention Program (ARPP) replaced the California Risk Management and Prevention Program effective January 1, 1997. Senate Bill 1889 requires businesses that handle threshold quantities of regulated substances on the federalist (Section 68.130 of Title 40 of the Code of Federal Regulations) to submit a Risk Management Plan by June 21, 1999. Businesses that handle more than a threshold quantity of a state regulated substance that is not also over the federal threshold quantities would be required to implement an ARPP upon request of the local government implementing agency. New businesses or users of regulated substances above threshold quantities will be required to submit a Risk Management Plan prior to using these substances. The City of Cupertino reviews the risk management plans as the Certified Unified Program Agency (CUPA) for businesses within the City. ■ The Federal Hazardous Material Transportation Act was passed to reduce the likelihood and minimize the impact of transportation accidents involving hazardous materials. The law specifies packaging requirements for different types of hazardous materials, and requires detailed manifesting of the contents of a vehicle to inform responders to a transportation accident of the materials involved. ■ Section 25536 of the State of California Health and Safety Code regulates siting of hazardous materials users, and requires special plans for any facilities which store, handle and/or emit certain quantities of hazardous materials. The City and the Bay Area Air Quality Management District (BAAQMD) locally administer this State � regulation. ■ The Uniform Building Code and Uniform Fire Code contain storage requirements for hazardous materials such as corrosives, flammable liquids, and gases. Many of the safeguards in the Uniform Building Code and Uniform Fire Code improve overall safety and provide for some containxnent in the event of a fire or accidental release. They are meant to protect the personnel who work in on-site structures and allow occupants to escape from unsafe buildings. They are intended to prevent releases of materials that could have off-site consequences or to protect the surrounding community by ensuring that containment occurs onsite. ■ AB 2185 and AB 3777 contain requirements for emergency response plans. The purpose of these plans is to assist local agencies in preparing for a hazardous materials spill. Emergency plans identify the potential for accidents in community, define a chain of command in the event of an emergency, outline escape routes if necessary, and provide other emergency procedures. The Plan provides the overall framework for emergency response to various types of hazards and contains a specific response action plan for hazardous materials incidents that is implemented by the responsible agencies. Each responsible agency then maintains detailed operation procedures for responses to hazardous materials problems. The following project specific measures would be included in the project to ensure that hazardous materials impacts are reduced to a less than significant level: 10 Resolution No. 6183 U-2002-06 Apri128,2003 Page 11 ■ All demolition activities would be undertaken according to OSHA, and EPA standards to protect workers, and offsite occupants from exposure to asbestos and lead based paint. ■ If loose or peeling lead-based paint is identified at the building(s) it will be removed by a qualified lead abatement contractor and disposed of in accordance with hazardous waste regulations. ■ If friable asbestos-containing materials are present, the materials will be abated by a certified asbestos abatement contractor in accordance with the regulations and notification requirements of the BAAQMD. ■ Building materials classified as hazardous materials would be disposed of in conformance with Federal, State and local laws. ■ Proof of conformance with regulatory requirements would be provided to the City at the time of issuance of demolition permits. Impact: Implementation of the project could result in non-point source pollution from oil and grease from parked cars, and herbicides and pesticides used to maintain the landscaping. Construction activities cold result in contaminated runoff from graded surfaces and soil accumulation in streets and driveways, which would increase sediments in stormwater, drainages, and local waterways. Mitigation: 'The project would be required to comply with the National Pollution Discharge Elimination System (NPDES) General Construction Activity Storm Water Permit administered by the Regional Water Quality Control Board. Prior to construction grading the applicant will file a"Notice of Inten� (NOI) to comply with the General Permit and prepare a Storm Water Pollutant Prevention Plan (SWPPP) which � will address measures that would be included in the project to minimize and conirol construction and post-construction runoff. These measures would include: ➢ Restricting grading to the dry season or meet City requirements for grading during the rainy season; ➢ Burlap bags filled with drain rock will be installed around storm drains to route sediment and other debris away from the drains; ➢ Providing temporary cover of disturbed surfaces to help control erosion during construction; , ➢ Provide permanent cover to stabilize the disturbed surfaces after construction has been completed. The project will include post-construction structural controls as permanent features of the project where feasible, and Best Management Practice (BMPs) for reducing contamination in storm water runoff. These measures could include regular sweeping of parking lots and driveways, installation of vegetative swales, installation of fossil filters or similar controls in storm water catch basins, and stenciling onsite catch basins to discourage illegal dumping. 11 Resolution No. 6183 U-2002-06 Apri128,2003 Page 12 31. NOISE Impact: The project may include stationary noise sources (i.e., roof-top mechanical equipment) that could exceed the noise standards of the General Plan. Mitigation: Once plans are developed showing the placement of rooftop mechanical equipment, the project plans would be reviewed by an acoustical specialist to calculate if the limits established in the Noise Element would be met. Noise attenuating measures would be required if the noise performance standards would be exceeded. Impact: The project could expose residences to noise levels in excess of standards established by the Cupertino General Plan and the state. Mitigation: Noise abatement measures would be incorporated into the design of building R-2. If residential land uses are located adjacent to De Anza Boulevard, noise control measures would be incorporated into the project's design so that the interior noise level would be reduced to 45 dBA or less. Sound rated building elements may also be necessary. Pursuant to the requirements of the State Building Code, adequate mechanical ventilation must be provided so that windows may be assumed to be closed at the discretion of the building occupants in order to control environmental noise intrusion. The building's design shall be reviewed by a qualified acoustical consultant during the design phase, and the necessary noise control treatments incorporated into the design. Usable open space would be situated at a location that provides acceptable noise levels. Impacts: Noise generating activities associated with demolition and construction of the proposed project would temporarily elevate noise level in the area surrounding the project site. Mitigation: In compliance with the City of Cupertino's Noise Ordinance, the following measures would be unplemented: ■ Grading, construction and demolition activities shall be allowed to exceed the noise limits of Section 10.48.040 of the City of Cupertino Noise Ordinance during daytime hours 7:00 am to 8:00 pm; provided the activity meets one of the following two criteria: (1) no individual device produces a noise level more than 87 dBA at a distance of 25 feet, or (2) the noise level on any nearby property does not exceed 80 dBA. ■ All noise generating construction equipment shall be fitted with high quality mufflers and abatement devices,which are in good condition. ■ Grading, street construction, or underground utility work is not allowed within seven hundred fifty feet of a residential area on Saturdays, Sundays, and holidays, or during the nighttime period, except for emergencies. ■ Nightkime construction activities shall not be allowed unless they meet the nighttime standards of Section 10.48.040 Daytime and Nighttime Maximum Noise Levels. For residential areas, the maximum noise level on the receiving property is 50 dBA. For non-residential the maximum is 55 dBA. 12 Resolution No. 6183 U-2002-06 Apri128,2003 Page 13 Additional measures could include the following: ■ Construct temporary plywood noise barriers to shield adjacent noise-sensitive land uses from consiruction noise prior to the demolition phase of the project. The temporary noise barriers should be at least 10 feet to 12 feet high to shield noise generated by heavy-equipment exhaust stacks. ■ Equip all internal combustion engine driven equipment with intake and exhaust mufflers which are in good condition and appropriate for the equipment. ■ Unnecessary idling of internal combustion engines should be strictly prohibited. ■ Avoid staging of construction equipment within 200 feet of residences and locate all stationary noise-generating construction equipment, such as air compressors and portable power generators, as far practical from existing noise sensitive receptors. Construct temporary barriers to screen stationary noise generating equipment when located in areas adjoining noise sensitive land uses. ■ Utilize "quiet" air compressors and other stationary noise sources where technology exists. ■ Route all construction traffic to and from the project site via designated truck routes. Prohibit construction related heavy truck traffic in residential areas where feasible. Prohibit construction truck traffic in the project vicinity prior to 7:00 a.m. or after 5:00 p.m., Monday through Friday. ■ Control noise from construction workers' radios to the point where they are not audible at existing residences bordering the project site. ■ Notify adjacent residents to the project site of the construction schedule in writing. ■ Designate a "noise disturbance coordinator" who would be responsible for responding to any local complaints about construction noise. The disturbance coordinator would determine the cause of the noise complaint (e.g., starting too � early, bad muffler, etc.) and would require that reasonable measures warranted to correct the problem be implemented. Conspicuously post a telephone number for the disturbance coordinator at the construction site and include it in the notice sent to neighbors regarding the construction schedule. (The City should be responsible for designating a noise disturbance coordinator and the individual project sponsor should be responsible for posting the phone number and providing construction schedule notices). Impact 1: Generation of Noise Levels Exceeding Performance Standards. The project may include stationary noise sources such as roof-top mechanical equipment and commercial uses that would have deliveries and loading areas that have the potential to exceed the noise performance standards. This is a potentially significant noise impact. Proposed commercial uses that have deliverv areas and receive regular deliveries have the potential to exceed noise performance standards at noise sensitive receivers. Policy 6-31 of the Cupertino Noise Element regarding delivery areas states: "Be sure new commercial or industrial " developments plan their delivery areas so they are awav from existing or planned homes". The nearest homes to the site are the multi-family �artments which lie across the Torre Avenue /Rodri�ues Avenue intersection. Due to 13 Resolution No. 6183 U-2002-06 Apri128,2003 Page 14 the distance between the noise source and receivers and the high ambient noise level at the intersection,it is unlikely that an im�act will result from onsite delivery activities. The pro�ect may include rooftop HVAC equipment for the new commercial /office or residential buildings. This equipment would have the potential to exceed the noise performance standards at the nearest noise sensitive residential receivers depending on the�roximity of the proposed buildin�s to the nearest receivers. At this stage of project plannin�, the exact specifications and locations of the mechanical equipment is not ,yet known. Project mechanical equipment should be designed to meet the noise performance standards at the nearest residential land uses. Rooftop mechanical equipment should not generate hourly noise levels above 60 dBA Leq during the daytime or 50 dBA Leq at night. This is a potentially significant, but mitigable noise impact. Mitigation Measures: Once plans are developed showing the placement of rooftop mechanical equipment, and the number and type of the equipment are known, the project plans should be reviewed by an acoustical specialist to calculate if the limits established in the noise performance standards would be met. Noise attenuating measures would be required if the noise performance standards would be exceeded. With the incorporation of the above mitigation measure, the impact would be considered less than significant. Delivery areas could be treated in the same manner. Impact 2: Exposure of Persons to Noise Levels in Excess of Standards The project could expose persons to noise levels in excess of standards established in the local general plan and noise ordinance, or applicable standards of other agencies. This is a potentially significant impact. Throughout the site, noise exposure levels range from 50 to 70 dBA Ldn. Noise levels are highest along De Anza Boulevard. Proposed residential and commercial uses adjacent to De Anza Boulevard could be exposed to noise levels of up to 71 dAB Ldn in the future, exceeding the level considered normally acceptable in the noise and land use compatibility guidelines set forth in the City's Noise Element for both residential and commercial/office uses. Building R-2, contains mixed-use commercial/office and residential uses and will border De Anza Boulevard to the northwest. The portion of the building adjacent to De Anza will be exposed to levels which exceed the standards. The city considers commercial/office uses "normally acceptable" in noise environments up to 70 dBA Ldn, and "conditionally acceptable" at noise levels between 70 and 75 dBA Ldn. Residential land uses at this noise exposure would fall under the city's "normally unacceptable" range and may exceed the standard of 45 dBA Ldn or less as set forth by the City of Cupertino and in Tit1e 24, Part 2 of the State Building Code. Normally, the exterior-to-interior noise level reduction provided by California construction is about 15 dBA with the windows open and about 25 dBA with the windows closed. Commercial buildings typically provide about 30 dBA of noise 14 Resolution No. 6183 U-2002-06 Apri128,2003 Page 15 reduction with windows closed. Therefore, where the exterior noise exposure is 60 dBA or less, interior noise levels would be expected to be 45 dBA or less, and in compliance with the 45 dBA Ldn interior noise standard. In areas where the exterior exposure is from 60 to 70 dBA, standard construction with the windows closed would be sufficient to achieve the 45 Ldn interior noise goal. In areas where the exterior noise exposure is greater than 70 dBA further abatement measures would need to be implemented. This is a potentially significant impact. Mitigation Measures: Incorporate noise abatement measures into the design of building R-2 and locate residential uses and outdoor-use areas furthest from De Anza Boulevard towards the eastern end of the building. Commercial uses which adjoin De Anza Boulevard will be subject to noise levels of up to 71 Ldn at ground level and possibly higher levels at subsequent floors in the future. Normal commercial retail construction with fixed windows with internal ventilation would typically provide enough noise reduction to meet standards. When architectural plans are developed, further studies may be helpful to meet the special need of occupants in particularly noise sensitive situations. If residential land uses are located adjacent to De Anza Boulevard, noise control treatrnents would need to be incorporated into the project's design so that the interior noise level would be reduced to an Ldn of 45 dBA or less. Sound rated building elements may be necessary. Pursuant to the requirements of the State Building Code, adequate mechanical ventilation must be provided so that windows may be assumed to be closed at the discretion of the building occupants in order to control environmental noise intrusion. The building's design shall be reviewed by a qualified acoustical consultant during the design phase, the necessary noise control treatments incorporated , into the design, and a report prepared and submitted along with the building plans prior to issuance of a building permit. The report shall specify that the necessary noise control treatments have been incorporated into the design. These measures would reduce the impact to a less-than-significant level. Impact 3: Project-Generated Traffic Noise. The operation of the proposed project will generate a slight increase in traffic volumes along the local roadway network serving the project site. This increase in traffic will not increase noise levels substantially at noise sensitive receptors in the project vicinity. This is a less than significant impact. Based upon a review of the traffic study prepared by Fehr £� Peers, traffic noise generated by the project would increase existing noise levels by about 0 to 2 dBA Ldn at nearby residential receptors in the project vicinity. The calculated increase in noise levels as a result of project-generated traffic would be less than significance threshold of 3 decibels. Traffic volumes on streets with relatively few existing vehicular trips (e.g., Torre Avenue and Rodriguez Avenue) will increase, yet the relatively low volumes and the resulting noise levels will be below ambient daytime noise levels in the area. The additional vehicular irips would add approximately 1 to 2 dBA Ldn along these roadways. Noise levels generated by traffic along Pacifica Drive would also increase by 15 Resolution No. 6183 U-2002-06 Apri128,2003 Page 16 about 1 to 2 dBA as a result of the increased vehicular trips resulting from the project. This is a less than significant impact. Mitigation Measures: None required. Impact 4: Project Construction Noise generating activities associated with the construction of the proposed project would temporarily elevate noise levels at noise sensitive receptors bounding the project site. This is a potentially significant impact. The construction of the project would generate noise, and would temporarily increase noise levels at adjacent receptors. Noise impacts resulting from construction depend on the noise generated by various pieces of construction equipment, the timing and duration of noise generating activities, and the distance between construction noise sources and noise sensitive receptors. Construction activities generate considerable amounts of noise, especially during the demolition phase and the construction of project infrastructure when heavy equipment is used. Tables 4 and 5 show typical noise levels generated by construction equipment at a distance of 50 feet from the source and at a distance of 50 feet from the construction activity center, respectively. The highest maximum noise levels generated by project construction would typically range from about 90 to 98 dBA at a distance of 50 feet from the noise source. Typical hourly average construction generated noise levels are about 81 dBA to 89 dBA measured at a distance of 50 feet from the center of the site during busy construction periods. Construction generated noise levels drop off at a rate of about 6 dBA per doubling of distance between the source and receptor. Shielding by buildings or terrain result in much lower construction noise levels at distant receptors. Typically, small residential,commercial, or office construction projects do not generate significant noise impacts when standard construction noise control measures are enforced at the project site and when the duration of the noise generating construction period is limited to one construction season(typically one year) or less. Construction noise associated with projects of this type are disturbances that are necessary for the construction or repair of buildings and structures in urban areas. Reasonable regulation of the hours of construction, as well as regulation of the arrival and operation of heavy equipment and the delivery of construction materials, are necessary to protect the health and safety of persons, promote the general welfare of the community, and maintain the quality of life. Construction noise impacts primarily result when construction activities occur during noise-sensitive times of the day (early morning, evening, or nighttime hours), the construction occurs in areas immediately adjoining noise sensitive land uses, or when construction durations last over extended periods of time. Limiting the hours when construction can occur to daytime hours is often a simple method to reduce the potential for noise impacts. In areas immediately adjacent to construction, controls such as constructing temporary noise barriers and utilizing "quiet" construction equipment can also reduce the potential for noise impacts. 16 Resolution No. 6183 U-2002-06 Apri128, 2003 Page 17 Mitigation Measures: In compliance with the City of Cupertino's Noise Ordinance, the following measures would be assumed to be in place: ■ Grading, construction and demolition activities shall be allowed to exceed the noise limits of Section 10.48.040 of the City of Cupertino Noise Ordinance during daytime hours 7:00 a.m. to 8:00 p.m.; provided the activity meets one of the following two criteria: o No individual device produces a noise level more than 87 dBA at a distance of 25 feet(7.5 meters); or o The noise level on any nearby property does not exceed 80 dBA. ■ All noise generating construction equipment shall be fitted with high quality mufflers and abatement devices which are in good conditions. ■ Grading, street construction, or underground utility work is not allowed within seven hundred fifty feet of a residential area on Saturdays, Sundays, and holidays, and during the nighttime period, except in emergencies. ■ Nighttime construction activities shall not be allowed unless they meet the nighttime standards of Section 10.48.040 Daytime and Nightkime Maximum Noise Levels. For residential areas the maximum noise level on the receiving property is 50 dBA. For nonresidential the maximum is 55 dBA. In addition to these measures provided by the city,we also recommend the following: ■ Construct temporary plywood noise barriers to shield adjacent noise-sensitive land uses from construction noise prior to the demolition phase of the project. The temporary noise barriers should be at least 10 feet to 12 feet high to shield noise generated by heavy-equipment exhaust stacks. ■ Equip all internal combustion engine driven equipment with intake and exhaust mufflers which are in good condition and appropriate for the equipment. ■ Unnecessary idling of internal combustion engines should be strictly prohibited. ■ Avoid staging of consiruction equipment within 200 feet of residences and locate all stationary noise-generating construction equipment, such as air compressors and portable power generators, as far practical from existing noise sensitive receptors. Construct temporary barriers to screen stationary noise generating equipment when located in areas adjoining noise sensitive land uses. ■ Utilize "quiet" air compressors and other stationary noise sources where technology exists. ■ Route all construction traffic to and from the project site via designated truck routes. Prohibit construction related heavy truck traffic in residential areas where feasible. Prohibit construction truck traffic in the project vicinity prior to 7:00 a.m. or after 5:00 p.m., Monday through Friday. ■ Control noise from construction workers' radios to the point where they are not audible at existing residences bordering the project site. ■ Notify adjacent residents to the project site of the construction schedule in writing. ■ Designate a "noise disturbance coordinator" who would be responsible for responding to any local complaints about construction noise. The disturbance 17 Resolution No. 6183 U-2002-06 Apri128,2003 Page 18 coordinator would determine the cause of the noise complaint (e.g., starting too early, bad muffler, etc.) and would require that reasonable measures warranted to correct the problem be implemented. Conspicuously post a telephone number for the disturbance coordinator at the construction site and include it in the notice sent to neighbors regarding the construction schedule. (The City should be responsible for designating a noise disturbance coordinator and the individual project sponsor should be responsible for posting the phone number and providing construciion schedule notices).
