Initial Study Page left intentionally blank x / 988 Howard Avenue IniUal Study Project Description 988 Howard Avenue Existing Project Setting The project site, 988 Howard Avenue, is located within the downtown area of Burlingame, in San Mateo County. The 0.35-acre parcel (Assessor Parcel Number (APN) 029-214-220} project site is surrounded by East Lane to the west, Howard Avenue south, and My�tle Road to the north and west. Existing Conditions and Land Use The project site is located within the Myrtle Road Mixed Use (MMU) planning area of the Burlingome Downtown Specific Plan.l MMU allows for a variety of small commerciai, residential, and retail uses. The MMU planning area is meant to serve as a buffer between the downtown commercial district and the residential neighborhoods located east of this area. The praject site is relatively flat and is located approximately 30 feet above mean sea level. The site is located app�oximately 0.2 miles east of the Caltrain tracks and approximately 1 mile west of the San Francisco Bay. The site is fully developed with a gas station/auto repair maintenance business. Vegetation is limited with several shrubs, but includes three (3) deciduous trees {approximately 4 to5 feet high) and one (1} City of Burlingame Street Tree (appraximately 12 feet high). The project site is currently occupied with two attached buildings; a one-story building with a footprint of approximately 1,000 square feet (sf) and a second attached one-story building of approximately 4,OQ0 sf. Fuel pumps and underground storage tank associated with a fuel station are located at the site; however, the gas station has not been active for approximately 2 years Access to the site is provided by driveways at Myrtie Road, Howard Avenue, and East Lane (see Figure 1). Residentia) land uses and several commercial businesses, including a fitness studio and market, surround the site to the east and north. Other key surrounding land uses are shown on Figure 1. As shown, the Caltrain corridor is to the southwest; the Buriingame Caltrain Station approximately p.2 miles west of site; Washington Elementary School approximately 0.1 miles northeast of the site; Burlingame High School is approximately 0.5 miles north of the site; and Washington Park within 0.1 mile of the project site. Proposed Project Components The project includes the construction of a three-story building that would include a mix of retail and commercial uses and an underground parking garage (see Table i). The building footprint would cover approximately 73 percent of the lot (11,160 sf of the 15,352 sf lot). The building height would be 45 feet from average top of curb, measured to the top of the parapet wall on the roof deck. A conditional use permit would be required to exceed the MMU zoning district allowance of 35-foot high structures. Approximately 68 standard commercial parking spaces (8 feet-6 inches x 18 feet) would be provided, which includes car stackers --- --- - that would provide 27 standard commercial spac�s. A detailed description of each level is provided below. The project plans are included as Appendix A. 1 The Downtown Surlingame Specific Plan area is framed by Oak Grove Avenue to the north, Anita Road to the east, Peninsula Avenue to the south, and EI Camino Real to the west.

Second Level - - -_— ... . _ The second level woufd include 11,180 sf of commercial space, including five exterior decks located around the perimeter of the space. Structural columns would be scattered throughout the commercial area for support far #he overall structure. A men and women's restroom and closet are located on northern side of the second level. 2 Initial Sfudy 988 Howard Avenue Third Level The third level would include 11,115 sf of commercial space, inciudi�g five exterior decks that would be located around the perimeter of the space. A men and women's restroom and closet would be located on northern side ofthe third level, directly above the second levei restrooms. Roof Levet The roof level would be accessible via two staircases and an elevator and would contain 3,800 sf of exterior deck space. The deck would include tables, lounge chairs, and landscaping for users of the building. A 42-inch tall glass railing would surround the deck and a low-height parapetwould extend past the deck an additional few feet.z The roof would also contain mechanical equipment and exhaust from the garage. Design and Landscaping The project would be designed with modern design concepts. The ground level lobby and store front would have large floor to ceiling glass windows. The commercial floor would have a similar open feel, with floor to ceiling windows and aluminum sun screens. The commercial floors would also include exterior decks that wrap around the building. The exterior siding would either be finished with stucco, metal panel, or composite wood ranging 6etween beige, brown, and grey colortones. The four existing trees and several shrubs located on the western portion of the project site along East Lane would be removed to accommodate project components. Landscaping on the ground level perimeter would include a variation of permeable pavers, decorative pebbles, traditional planters on top of 42-inch concrete structures, evergreen shrubs, Ginkgo Biloba street trees, and o#her tree planting in 24-inch box structures. The roof level would be landscaped with traditional4-foot square planter pots with 24-inch palm trees or drought tolerant evergreen trees. Utilities The Burlingame Public Works Department provides water and wastewater service to the project site. The project site is connected to the City's utility infrastructure and includes 10-inch water lines and 6-inch sanitary sewer lines. The new building would tie-in to these existing lines. The Department of Public Works has indicated that the 6-inch sanitary sewer line that serves the subject property is at or near capacity. The applicant will need to do an analysis to determine if the sewer main requires upsizing. This analysis will be reviewed by the City and if required, the applicant will be required to pay for their pra-rata share of the upsizing or a designated run of the line, the details of which would be determined by the Department of Public Works prior to building permit approval. The existing 10-inch water line is su�cient to provide for the increased need in water usage for the proposed uses; however new construction is required to compfy with ____- ___. _ _ _ California Fire Code requirements for fire flow, based on the size of the building and type of construction, and hydrant spacing. Upon building permit submittal Central County Fire Department will require that the project comply with State fire code for emergency water supply (hydrants) with regard to the increase of square footage at the project site and necessary flow rate (gallons per minutes); if the existing 10-inch canno# meet Z A parapet is a low protective bar�ier along the edge of a roof, terrace, balcony, etc. 3 Initlal Study 988 Howard Avenue the flow rate the� the applicant would be responsible for upsizing the water line. 7he Street and Sewer Division of the Department of the City Public Works Department maintains Burlingame's stormwater infrastructure. The project site is connetted to an existing 15-inch stormwater line and the new building would tie-in to this existing tine to convey stormwater infrastructure. Bio-swales for stormwatertreatment and ' drainage around the project site would be installed as well. Best ma�agement practices would be implemented with regard to site development, energy efficiency, water conservation, and pollutant cont�ol. Construction The existing buildings, concrete, and paving on the site would be demolished and removed as part of the project. Additionally, the projed wauld remove the underground fuel pumps and storage tank. Principal construction would take between 12 to 18 months. 7he walls of the basement level would require shoring or bracing technique to retain surrounding areas below grade and would not exceed 12 feet in excavation. The project would remove approximately 6,000 cubic yards of soil, which would be disposed af at either �x Mountain (Half Moon Bay) or Dumbarton Quarry (Newark). Typical construction equipment would include dozers, graders, tractors, cranes, forklifts, and generators. No pile driving would be required. Materials would be staged on site, mostly on the eastern portion of the site (adjacent to Myrtle Rd). Construction would occur during the construction hours allowed bythe Burlingame Municipal Code, Section 18.07.110, specifically: Weekdays: 7:00 am — 7:00 pm Saturdays: 9:00 am — 6:00 pm Sunday and Hotidays: 10:00 am —6:00 pm 2013 California Green Building Code The p�oject would comply with the 2013 California Green Building Code and implement energy efficiency measures to comply with the 2013 California Building Energy Efficiency Standards. Water efficiency and conservation measures such as metering, efficient plumbing fixtures, and wastewater reduction would be implemented. Furthermore, outdoor landscaping would be designed with automatic irrigation controllers and sensors to reduce outdoor water usage. The project would install a heating, ventilation, and air conditioning unit (HVAC) and refrigeration system that are energy efficient and reduce potential leak reduction. Access and Circulation The praject site is located just west of US 101 and east of EI Camino Real; both majar traffic corridors providing access to Burlingame. Currently there are four driveways on the site, two would be removed and vehicles would access and exit the project site via entrances either on Howard Avenue or East Lane. The project - � location would provide easy access to the Burlingamc Caltrain stati�n. @icycle parking areas vrould be provided as welL Future employees in the building would be within walking distance to the downtown portion of 6urlingame, on the west side of the Caltrain corridor, where there are a number of restaurants and amenities. 4 IniUal Study Project Approvals The project requires the following approvals: 988 Howard Avenue • Design review— required for new commercial buildings to determine (CodeSection 25.57.010(c)). • Conditional Use Permit for building height (45'-0" proposed whe�e 35'-0" is the maximum allowed in the Myrtle Road Mixed Use District) (Code Section 25.34.055). • Rear Setback variance to relocate the formal front entrance on East Lane (proposed rear setback of 10'-0" where a 20'-0" is the minimum required) (Code Sedion 25.34.060). • Parking variance for reduction of required on-site parking by 5 spaces or consideration far the approval of a car share program. If the City approves the car share program, the project applicant would withdraw the request for parking variance because the car share program would qualify the project for a 10 percent reduction in parking (Code Section 25.70.Q10(a)). • Adoption of a mitigated negative declaration — California Environmental Quality Act (CEQA) clearance • Occupational Safety and Health Administration (OSHA) permit is to be obtained for the shoring at the excavation in the basement per CAL/OSHA requirements • Stormwater Pollution Prevention Plan (SWPPP) to obtain National Pollutant Discharge Elimination System (NPDES) permit • Grading permit • Tree removal permit from the City Director prior to construction IniGal Study Environmental Impacts /ssues �and Supporiinp informaflon SourcesJ: i.

Burlingame is surrounded by the City of Milibrae to the northwest, the Bay to the east, the City of San Mateo to the southeast, and the Town of Hillsborough to the southwest. Most of the City is located on gently sloping valley floor and is a highly developed, urban/suburban area. The western portions of the City are located on foothills rising to the Santa Cruz Mountains that offer scenic views of the 5anta Cruz Mountains, the eay, and the East Bay Hills. The project site lies within the Myrtle Road Mixed Use Area (MMUj in the northeastern portion of the Burlingame powntown Specific Plan area. According the Burlingame Downtown Specific Plan lnitial Siudy/Mitigated Negative Declaration (Burlingame Downtown Specific Plan 1S/MND), Mixed Use Areas should be encouraged to create active pu6lic places. New buildings would contribute to existing character and pedestrian nature of downtown, with active storefronts, windows, and doors at ground level. Architecture would include the types of details that are cammon to Burlingame, and would use similar materials, colors, proportions, window types, and overall compositions. This project is located on a flat, urbanized site surrounded by retail, commercial, and residential uses. Existing development on the project site includes a gas station and an automobile repair business housed in two T T � attached single-story commercial buildings. Remaining portions of the site are fully paved and used for automotive storage. Four trees and small patches of existing landscaping are scattered around the edges of the site. Sightlines within the project vicinity are typically restricted by flat topography, law elevation, and surrounding development. 6 IniUal Study 988 Howard Avenue The surrounding area consists of one- and two-story buildings with an occasional taller structure. The lmmediate neighborhood includes an automotive service garage abutting the property to the north; an automobile storage lot across Howard Avenue; a two-story mixed use building across the Myrtle Road; and on- street parking, automobile storage, and the Caltrain railroad tracks, approximately 0.2 miles west, a�ross East Lane. Many commercia) structures in the area have no setback from the road, while other structures have paved parking lots between the sidewalk and the front of the building. A shadow report was prepared as part of the proposed projed in response to public concern of potentlal aesthetic impacts of the project. While shadow effects are not a CEQA topic, this report is included as Appendix B. Discussion a) Would the project have a substantial adverse effect on a scenit vista? (No Impact) According to the City of Burlingame General Plan (general plan), impor#ant vistas include the hillside leading to the Skyline Ridge as seen from the Bay plain, and the Bay as seen from the hillside. The project would not impact either scenic resource. Public views of the foothills rising to the Santa Cruz Mountains are obscured by existing development and landscaping in the project vicinity. The project would not alter public views of the Bay from the hillside, which would be relatively similar in scale to other existing structures in the Burlingame Downtown Specific Plan area. No impact to scenic vistas would occur. bj Would the project substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway? (No Impact) The intent of ihe California Scenic Highway Program is to protect and enhance California's natura! beauty and to protect the social and economic values provided by the state's scenic resources. State scenic highways are officialfy designated by Scenic Highways Advisory Committee. According the General Plan Scenic Roads and Highways Element, the project is not located near a state scenic highway. Therefore, no impact would occur. c) Would the project substantially degrade the existing visual character or quality of the site and its surroundings7 (Less Than Significant) Construction Construction of the proposed project would involve earthmoving operations and grading activities. As a result, construction equipment, const�uction vehicles, staging areas, and associated construction debris would be visible on the project site for the duration of construction (approximately 12-18 months). The visual character _._ __-_.. __ and quatity of the site would change for a temporary period of time, depending on the work and equipment used. However, the visual effects of construction activities would be similar to other types of development and construction that typically occur within the area and are temporary in nature. IniGal Study Operation 9$S Howard Avenue The proposed prajact would construct a three-story mixed-use structure with a rooftop garden on a currently developed parcel surrounded by residential neighborhoods, commercial uses, and transportation corridors. As discussed below, the project is designed to be compatible with the light/indust�ial vernacular of the existing neighborhood while incorporating a visuai transition fnto the neighboring lyon Hoag neighborhood and creating a pedestrian-oriented atmosphere. Figure 2 depicts renderings of the proposed project. The proposed structure is located Qn the no�thern portion of #he site, adjacentto the northern property line to maximize separation from residentiai developments. The solid vertical mass along East Avenue is consistent with the industrial buildings that face the railroad tracks, while staggered surfaces along Howard Avenue and Myrtle Avenue prevent the structure from looming over the sidewalk and other public areas. The exterior siding would either be finished with stucco, metal panel, or composite wood ranging between beige, brown, and grey color tones. The various architectural textures,.profiles, materials, and color pailets were selected based on their consistency with the visual character of the area; however, the overall design reflects a more madern architectural style than what currently exists in the surrounding community. The project applitant proposes a three-story structure that would measure 45 feet to the top of the parapet from average top of curb. The new structure would greatly exceed the height of the existing single-story building by approximately 35 feet. In response, the p�oject deslgn incorporated upper-story setbacks and balcanies to reduce the stnicture's impasition on the surrounding area. The open roof level would consist of a 3,800 sf exterior deck with landscaping, a glass railing, and a(ow-height parapet. The roof would alsa contain mechanical equipment and exhaust from the garage. The project has been designed forthe pedestrian nature of the Burlingame powntown Specific Plan area. The ground level would feature large floor-ta-ceiling glass windows to provide active storefronts. Commercial floors would have an open feel, with floor-to-ceiling windows, aluminum sun screens, and exterior decks that wrap around the building. The project would also incorporate 820 square feet of landscaping on the ground level perimeter that would include a variety of permeable pavers, decorative pebbles, traditional planters, evergreen shrubs, and street trees. Parking would be underground aod on the ground level. The project applicant is requesting a Rear Setback Variance to locate the formal front yard on East Lane. This variance would allow a 20-foot setback along Myrtle Road, which would be landscaped to create a well-scaled transitian along Howard Street into the mixed-use Lyon Hoag neighborhood. The variance would also result in a 10-foot setback along East Lane. This smalle� setback would have less of a visual impact to East Lane, which is essentially a frontage road alongside the Caltrain tracks that consists of surface parking and low-scale industrial buildings converted into offices. Although the height of the proposed building would be 45-feet, which istaller than the surrounding buildings, the helght is allowed with a Conditional Use Permit and this scale of development was envisioned as part of the Burlingame Downtown Specific Plan. The increased (andscaping and articulated fayade wauCd provide a more pedestrian atmosphere consistent with the SpecificPlan. The project would not substantially deg�ade the visual quality and character of the site and project area and therefore would have a less-than-significant impact. Initial Study 988 Howard Avenue d) Would the project create a new source of substantial light or glare which would adversely affect day or nighttime views in the area? (Less Than Signi�cant with Mitigation Incorporated) The project site is currently developed and urbanized. Streetlights, exterior commercial lighting and vehicular lights exist in the surrounding area and along adjacent corridors. The new building would contribute additional sources of light; however exterior lighting shall be designed and installed to comply with extsting regulations to reduce light poilution. The glass surfaces on the proposed structure would result in increased suniight reffection, ambient light, and glare beyond existing conditions. This is considered a potentially significant impact. The following mitigation measure is anticipated ta reduce this impact to a less-than-significant level. Mitigation Measure AES-1: The projed developer shali install low-profile, low-intensity lighting directed downward to minimize light and glare. Exterior lighting shall be low mounted, downward casting, and shielded. In general, the light footprint shall not extend beyond the periphery of each property. Implementation of exterior lighting fixtures an all buildings shall also comply with the standard California Building Code (Title 24, Building Energy Efficiency Standards) to reduce the lateral spreading of light to surrounding uses, consistent with Burlingame Municipal Code Section 18.16.030 that requires that all new exterior lighting for commercial developments be designed and located so that the cone of light and/or glare from the light element is kept entirely on the property or below the top of any fence, edge or wall. lnitial Study lssues (and Supporting lnformatlon Sourcesj: 988 Howard Avenue Cess Than Sipnlfkant or SlgnffJcortt Poteniially wlth Less Than Sfynl�cont MitiQatlon Siqntficant lmpoct Intotporation /mpact Na fmpoct z. AGRICULTURE RESUURCES— In determining whether impacts to agricuitural resources are signiflicant environmental effects, lead agencies may refer to the California Agricultural Land Evaluation and 5ite Assessment Model (1997) prepared by the California D2partment of Conservation as an optional model to use in assessing impacts on agriculture and farmland.

The project site is not designated for agricultural uses in the General Plan Land Use Map; therefore, the project woufd not conflict with existing zoningforagricultural use. Furthermore, the proposed project site is cu�rently in an urban setting and falls within a planning area of the Burlingame Downtown Specific Plan area, which contains land use policies intended to promote and expand development. Consequently, the project woufd not result in farmland conversion to non-agricultural use.

Air Pollutants of Concern The San Francisco Bay Area (Bay Area) meets all ambient air quality standards with the exception of ground- level ozone, respirable particulate matter (PMla), and fine particulate matter (PM�). High ozone levels are caused by the cumulative emissions of reactive organic gases (ROG) and nitroge� oxides (NOxj. These precursor pollutants react under certain meteorological conditions to form high ozone levels. Controlling the emissions of these precursor pollutants is the focus of the Bay Area's attempts to reduce ozone levels. The -" highest ozone levels in the Bay Area occur in the eastern and southern inland valleys that are downwind of air pollutant sources. High ozone (evels aggravate respiratory and cardiovascular diseases, reduced lung function, and increase coughing and chest discomfort. 11 loitial Study 988 Howard Avenue Particulate matter is another pro6lematic air poliutant of the Bay A�ea. Particulate matter is assessed and measured in terms of respirable particulate matter or particles that have a diameter of 10 micrometers or fess (PMlo) and fine particulate matter where particles have a diameter of 2.5 micrometers or less (PM�.S). Elevated concentrations of PMlo and PMz,s are the result of both region-wide (or cumulative) emissions and localized emissions. High particulate matter leveis aggravate respiratory and cardiovascular diseases, reduce lung function, increase mortality (e.g., lung cancerj, and result in reduced lung function growth 1n children. Toxic Air Contaminants Toxic Air Contaminants (TAC) are a broad class of compounds known to cause morbidity or mortality (usually because they cause cancer} and include, but are not limited to, the criteria air pollutants. TACs are found in ambient air, especially in urban areas, and are caused by industry, agriculture, fuel combustion, and commercial operations (e.g., dry cleaners). TACs are typically found in low concentrations, even near their source (e.g., diesel particulate matter [DPM] near a freeway). Because chronic exposure can result in adverse health affects, TACs are regulated at the regional, state, and federal level. Diesel exhaust is the predominant TAC in urban air and is estimated to represent about three-quarters of the cancer risk from TACs (6ased on the Bay Area average). According to the California Air Resources Board (CARB), dieset exhaust is a complex mixture of gases, vapors, and flne particles. This complexity makes the evaluation of health effects of diesel exhaust a complex scientific issue. Some of the chemicals in diesel exhaust, such as benzene and formaldehyde, have been previously identified as TACs by the CARB, and are listed as carcinogens either under the state"s Proposition 65 or under the Federal Hazardous Air Pollutants programs. CARB adopted and implemented a number of regulations for stationary and mobfle sources to reduce emissions of DPM. Several of these regulatory programs affect medium and heavy duty diesel trucks that represent the bulk of DPM emissions from California highways. These regulations include the solid waste collection vehicle (SWCV) rule, in-use public and utility fle�ts, and the heavy-duty diesel truck and bus regulations. In 2007, CARB approved a new regulation to reduce emissions of DPM and nitrogen oxides from existing on-road heavy-duty diesel fueled vehicles. The regulation requires affected vehicles to meet specific performance requirements between 2014 and 2023, with all affected diesel vehicles required to have 2010 model-year engines or equivalent by 2023. These requirements are phased in over the compliance period and depend on the model year of the vehicle. BAAQMD is the regional agency tasked with managing air quality in the region. At the state level, the CARB (a part of the California Environmental Protedion Agency [EPAJj oversees regional air district activities and ` regulates air quality aYthe state level. The BAAQMD has recently published California Environmental Quality Act (CEqA) Air Quality Guidelines that are used in this assessment to evaluate air quality impacts of projects. 5ensitive Receptors There are groups af people more affected by air potlution than othe�s. CARB has identified the following persans who are most likely to be affected by air pollution: children under 14, the elderly over 65, athletes, and people with cardiovascular and chronic respiratory diseases. These groups are classifed as sensitive receptors. Locations that may contain a high concentration of these sensitive population groups include residentia) areas, hospitals, daycare facilities, elder care facilities, elementary schools, and parks. The ciosest 12 Initial Study 988 Howard Avenue off-site sensitive receptors are residences located above the street Meve( retail shops on the corner of Howard Avenue and Myrtle Road, approximately 50 feet across from the project site. Other sensitive receptors are located, across My�tle Road, to the north, northeast, and east of the project site. Significance Thresholds In June 2010, BAAQMD adopted thresholds of significance to assist in the review of projects under CEQA. These thresholds were designed to establish the level of air pollution emissions that could cause significant environmental impacts under CEQA and were posted on BAAQMD's website and included in the Air District's updated CEQA Guidelines (updated May 2011j.

BAAQMD (Alameda Superior Court Case No. RGI0548693j. The order requires BAAQMD to set aside its approval of the thresholds until it has conducted environmental review under CEQA. The ruling made in the case concerned the environmentai impacts of adopting the thresholds and how the thresholds woutd indirectly affect land use devefopmen# patterns. In August 2013, the Appellate Court struck down the lower court's order to set aside the thresholds. However, this litigation remains pending as the California Supreme Court recently accepted a portion of CBIA's petition to review the appellate court's decision to uphold BAAQMD's adoption of the thresholds. The specific portion of the argument to be considered is in regard to whether CEQA requires consideration of the effects of the environment on a project (as contrasted to the efFects of a project on the environment). Therefore, the significance thresholds contained in the 2011 CEQA Air Quality Guidelines are applied to this project. The project site is located in the northeastern portion of San Mateo County, within the San Francisco Area Air Basin. Ambient air quality standards have been established at both the state and federa( level. The San Francisco Area Air Basin meets all such ambient air quality standards requirements, with the exception of ground-level ozone, respirable particulate matter (PM�) and fine particulate matter (PMz.$). High ozone levels are caused by the cumulative emissions of reactive organic gases (ROG) and nitrogen oxides (NOX). These precursor pollutants react under certain meteorological conditions to form high ozone levels. Controlling the emissians of these precursor pollutants is the focus of the Bay Area's attempts to reduce ozone levels. Discussion a) Conflict with or obstruct implementation of the applicable air quality plan? (No Impact) As noted above in the setting discussion, the San Francisco Bay Area Air Basin is in non-attainment for state and federal standards for 03, PMZS and PMla. Steps needed to achieve compliance with these regulations have been identified, as described below. The state-mandated regional air quality plan is the Clean Air Plan. The Clean Air Plan includes about 55 control measures that are intended to reduce air pollutant emissions in the Bay Area either directly or indirectly. The control measures are divided inta five categaries that include: ■ Measures to reduce stationary and area sources ■ Mobile source measures ■ Transportation control measures �■ Land use and local impact measures ■ E�ergy and climate rneasures A project would be determined to con#lict with or obstruct implementation of the regional air quality plan if it would be inconsistent with the regional growth assumptions, in terms of population, employment, or regional growth in Vehicle Miles Traveled (VMT). The emission strategies in the Clean Air Plan were developed, in part, 14 Ini6a1 Study 988 Haward Avenue on regional population, housing, and employment projections prepared by the Association of Bay Area Governments (ABAG). The project is cansistent with the Myrtle Mixed Use zoning for the site. As such, the use of this site for commercial purposes is already included in the Clean Air Plan. The project would not directly increase the City's population as it does not include residential units. The existing garage and automobile repair shop, on the project site, would be replaced with a single three-story mixed-use building. Due to the close proximity of public transit, including Caltrain, Samtrans, and BART, no net increase in traffic is anticipated with project implementation. Consequently, development of the project would not conflict with population and VMT projections used to develop the Clean Air Plan planning projections (see Section 16). The project would not obstruct implementation of these plans, and therefore no impact would occur. b) Violate any air quality standard or contribute substantially to an existing or projected air quality violation? (Less Than Significantj BAAQMD has established thresholds of significance for the non-attainment air pollutants and their precursors. These thresholds are for azone precursor pollutants (ROG and NOxj, PM,o and PM2.5, and apply to both the construction period and the operational period impacts. The California Emissions Estlmator Model (CaIEEMod) Version 2013.2.2 was used to predict emissions from construction of the site assuming full build out af the project, by inputting the project land use types and size, and anticipated construction schedule. The proposed project land uses were factored into the CaIEEMod land use categories as follows: 22,295 sf of "General Office Building," 1,325 sf of "Strip Mall" (which refers to the proposed retail fand uses}, and 68 parking spaces entered as "Enclosed Parking with Elevator." Additionalfy, the project would require approximately 6,000 cubic yards (cyj of soil export, and default construction settings for the proposed project footprint, all of which were accounted for in CalEEmod. Construction The air quality emissions modeling assumes the project would be constructed over 123 work days (e.g., approximately b months) as a conservative scenario. Average daily emissions were computed by dividing the totat construction emissions by the number of construction days. Table 3 below shows average daily construction emissions of ROG,'NOw PMIo exhaust, and PMZ,S exhaust during tonstruction of the project. As indicated in Table 3, predicted project emissions would not exceed the BAAQMD significance threshalds (see Appendix C for additional information).Construction activities would generate dust and equipment exhaust on a temporary basis during construction activities from site preparation, demolition, ground disturbance, and the --- _ operation of construction equipment and other vehicles. The effects af construction activities would be locally elevated (evels of TACs, ozone precursors (ROG and NOx), PMlo and PM�,S downwind of construction activity (see Table 3). Construction dust has the potentia) for creating a nuisance at nearby properties. Standard Permit Conditions require that all basic BAAQMD BMPs be implemented, as described in Mitigation Measure AQ-1 below. 15 Initial Study 988 Howard Avenue Implementation of the measures recommended by BAAQMD and listed below would reduce the air quality and fugitive dust-related impacts associated with grading and new construction to less than significant.

All equipment shall be checked by a certified mechanic and determined to be running in proper condition prior to operation. 8. Post a publicly visible sign with the telephone number and person to contact at the City of Burlingame regarding dust complaints, This person shall respond and take corrective action within 48 hours. The BAAQMD's phone number shall also be visible to ensure compliance with applicable regulations. Operation In the 2011 CEQA Air Quality Guidelines update, BAAQMD identifies screening criteria for the sizes of land use p�oje�ts that could result in sig�ificant air pollutant emissions. For operational impacts, the screening project size is identified at 346,006 sf for commercial developments. Office p�ojects of smaller size would be expected to have less-than-significant impacts with respect to operational-period emissions. 5ince the project proposes to operate at 22,Z95 sf of office space and 1,325 sf of retail, it is concluded that emissions would be below the 16 Initial Study 98& Howard Avenue BAAQMD significance thresholds for the operational period. Additionally, development would be nearexisting transit with regionai connections and could reduce vehicle-related emissions, as well as potentially provide employment for the surrounding residential uses. Carbon monoxide emissions from traffic generated by the project would be the pollutant of greatest concern at the local level. Congested intersections with a large volume of traffic have the greatest potential to cause high-localized concentrations of carbon monoxide, Air pollutant monitoring data indicate that carbon monoxide levels have been at healthy levels (i.e., below state and federai standards) in the Bay Area since the early 1990s. As a result, the region has been designated as attainment for the standard. The highest measured level over any 8-hour averaging period during the last 3 years in the Bay Area is less than 3.0 parts per millian (ppm), compared to the ambient air quality standard of 9.0 ppm. According to the Air Quality and Greenhouse Gas Assessment prepared for the project, interseckions affected by the project would have traffic volumes less than the BAAQMD screening criteria. Therefore, the project would not cause a violation of an ambient air quality standard for C0. Project construction and operation would not cause a violation of any air quality standards or contribute substantially to an existing or projected air quality violation. Therefore this impact would be less than significant. c) Result in a cumulatively considerable net increase of any criteria poilutant far which the project region is non-attainment under an applicable federal or state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors)? (less Than Significant with Mitigation Incorporated) Past, present and future development projects contribute to the region's adverse air quality impacts on a cumulative basis. By its very nature, air pollution is largely a cumulative impact. No single project is sufficient in size to by itself, result in nonattainment of ambient air quality standards. Instead a project's individual emissions contribute to existing cumulatively significant adverse ai� quality impacts. If a project's contribution to the cumulative lmpact is considerable, then the project's impact on air quality would be considered significant. The BAAQMD CEQA Guidelines state that a significant air quality impact would result if the project would result in a cumulatively cansiderable net increase of any criteria pollutant or a precursorto that pollutant for which the project region is non-attainment under an applicable national or state ambient air qualfty standard (including releasing emissions, which exceed quantitative thresholds for 03 precursors). This is judged by comparing dire+ct and indirect project emissions to the BAAQMD significance thresholds of 54 pounds per day -- - for ROG N0 or PM . and 82 ounds er da for PM Annual si nificance thresholds are 10 tons er ear � w z s, P p Y io• 8 p y for ROG, NO�, or PM2,5i and 15 tons per yearfor PMlo• As stated above, according to BAAQMD, implementation of the proJect would, therefore, result in a less-than- significant cumulative impact to air quality from criteria air pollutant and precursor emissions. Given the nature o#the proposed use (i.e., office/retail) and given the mixed-use land use type, the operational criteria pollutant screening size for the project is 346,000 sf. The project would implement 22,295 sf of office space 17 Initial Study 988 Howard Avenue and 1,325 sf of retaii, and would therefore be below the screening criteria developed by BAAQMD. Given this, the project would not exceed the poilutant emissions thresholds. Therefore, the project's contribution to cumulative air quality impacts is not considered cumulatively considerable. Due to #he project size, operational period emissions would be less than significant. However, because the project proposes to demolish existing facilities ansite, modeling of construction emissions was conducted to quantify project impacts (see Table 3�. The BAAQMD CEQA Air Quality Guidelines consider these impacts to be less than significant if best management practices (BMPs) are employed to reduce these emissions. Implementation of Mitigation Measure AQ-1 would reduce any violation or contribution to existing or projected air quality violations to a less-than-significant level. d) Expose sensitive receptors to substantial pollutant concentrations? (Less Than Significant with Mitigation Incorporated) Operation of the project is not expected to cause any localized emissions that could expose sensitive recepto�s to unhealthy air pollutant levels. No stationary sources of TACs (typically factories, refineries, power plants, etc.), are praposed as part of the project. Construction activity would generate dust and equipment exhausts on a short-term temporary basis. The project would not introduce any new sensitive receptors to the area. Construction equipment and associated heavy-duty truck traffic could generate diesel exhaust, which is a known 7AC. Diesel exhaust and PMzs can pose both potential health and nuisance impacts to nearby receptors. The nearest sensitive receptors are residences located above the street level retail shops on the corner of Howard Avenue and Myrtle Road, approximately 50 feet east of the project site. There are other residences located further from the project site, across Myrtle Road to the north, northeast, and east. Refined community risk assessment modeling forthe project buildout was conducted using CaIEEMod. BAAQMD significance thresholds for cancer causing carcinogens are set at 0.3µ/m3 for PMu, and 5µ/m3 for Diesel Particulate Matter (DPM). Lifetime cancer risks associated with project implementation were calculated using a dispersion model; the maximum modeled annual PM�,S concentration was 0.22µ/m3, and the maximum modeled annual residential DPM concentration was 0.212µ/m3, both of which are significantly lowerthan the BAAQMD significance thresholds. During project construction, the incremental residential childhood cancer risk at the maximally exposed individual (MEI) receptor would be 18.6 in one million and the maximum incrernental residential adult cancer risk would be 1.0 in one million. Cancer risk and non-cancer impacts to adult residents are below BAAQMD significance thresholds of 10 in one million or greater for PMZ,S and DPM (see Appendix C). However, the residential childhood cancer risk of 18.6 in one million is above the BAA4MD threshold of 10 in one million, and would be considered a significant impact. Mitigation Measure AQ-2 would ---- -- -- reduce risks associated with construction emissions, and lncreased cancer risk, to a tess than si;nificant level. The implementation of Mitigation Measure AQ-1 and Mitigation Measure AQ-2 would further reduce impacts from fugitive dust. Any impacts associated with project implementation and the exposure of sensitive receptors to substantial pollutant concentrations would be less than significant. Mitigation Measure AQ-2. The contractorshall select specific equipment during construction in order to minimize emissions. The equipment selection would include the �egulation that all diesel-powered equipment larger than 50 horsepower and operating on the site for more than two days continuously shall, at a minimum, meet the U.S, EPA particulate matter standards for Tier 2 engines ar equivalent 18 Inidal Study 988 Howard Avenue e) Would the project frequently create objectionable odors affeding a substantial number of people? (Less Than Significantj The project would generate localized emissions of diesel exhaust during construction from equipment operation and truck activity. These emissions may be noticeable from time to time by adjacent receptors. However, they would be localized and are not likely to adversely affect people off site by resulting in confirmed odor complaints. No sources of significant odors that would Gause compiaints from surrounding uses are anticipated with the construction of the mixed use building; the proposed uses include office space and retail, neither of which typically produces objectionable odors. Therefore any impacts associated with the creation of frequently occurring, objectionabie odors would be less than significant. 19 Ini6ai Study 988 Howard Avenue Leu Than Signlfiwnt or Sipn�cont Potentiaqy with LessThaq Slgni�cont Mitigatlon Signifitant issaes (ond Supportinp Informatlon SourcesJ: Impact lncorporation Jmpact No ►mppct a.

The project site is located in an urban area and is surrounded by dense commercial and residential devebpment. The project site is completely developed and is currently used as a gas station and auto repair maintenance business. Vegetation on the site is limited to small areas of landscaping along thesidewalk and to several non-native trees along the fence line. 20 Initial Study DISCUSS1011 988 Howard Avenue a) Have a substantial adverse effect, either directly orthrough habitat modifications, on any species identified a5 candidate, sensitive, or special status species in local or regional plans, policies, regutations, ar by the California Department of Fish and Game or US Fish and Wildlife Service� (Less Than Significant with Mitigation Incorporated) The California Natural Diversity Data Base (CNDDB) was reviewed to identify the location of special-status species documented in surrounding areas, and the suitability of onsite habitats to support special-status species was evaluated during the August 2015 site visit. Based on the CNDDB, no specia!-status species have been documented on the project site or within approximately 2 miles of the site. The project site does not provide suitable habitat for any regionally occurring special-status plant or wildlife species forthe following reasons: (1) the site is in a densely developed urban area and is isolated from areas of natural habitat; and (2) the site is paved and is being actively used as a gas station and auto repair maintenance shop. Therefore, impacts to speciaf-status plant and wildlife species from development and aperation of the project are not expected to occur. The trees on and near the project site provide potential nesting habitat for common, urban adapted hird species. The active nests of most native bird species are protected by the Migratory Bird Treaty Act (16 U.S.C. 704) and the California Fish and Game Code (Section 3503j. The proposed project may require the removal of four trees, which could result in the loss of an active bird nests. Additionally, construction noise has the potential to disturb nesting potentially occurring in nearby areas. Therefore, the loss of arr active bird nest protected by the Migratory Bird Treaty Act and/orthe California Fish and Game Code is a potentially significant impact. Mitigation Measure BI�-I; lf construction activities would commence anytime during the nesting/breeding season of native bird spectes potentially nesting near the site (typically February through August in the project region), a pre-canstruction survey for nesting birds would be canducted by a qualified biologist within two weeks of the commencement of construction activities. The pre-construction survey would encompass the project site and surrounding area, within 150 feet, so as to account for construction-related noise. If active nests are found in areas that could be directly affected or are within 150 feet of construction and would be sub�ect to prolonged construction-related noise, a no-disturbance buffer zone should be created around active nests during the breeding season or until a qualified biologist determines that all young have fledged. The size of the buffer zones and types of construction activities restricted within them would be determined by taking into account factors such a� the following: ■ Noise and human disturbance levels at the construction site at the time of the survey and the noise and disturbance expected during the construction activity; ■ Distance and amount of vegetation or other screening between the construction site and the nest; and ■ Sensitivity of individual nesting species and behaviors of the nesting birds. 21 I�U� Study 988 Howard Avenue b) Have a substantiat adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, regulations, or by the California Department of Fish and Game or US Fish and Wildlife Service? [No Impact) During the August 2015 site visit, it was confirmed that no riparian habitat or other sensitive plant communities exist on or nearthe project site. Therefore, no impacts to riparian habitat and other sensitive plant communities would occur. c) Have a substantiai adverse impact on federally protected wetlands as defined by Section 404 of the Clean Water Act (including but not limited to: marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? (No Impact) During the August 2015 site visit, it was confirmed that no creeks, wetlands, and other potentially jurisdictional resources are present on or near the project site. 7herefare, no impacts to federally protected wetlands and other waters would occur. - d) tnterfere substantially with the movement of any native resident or migratory fish or wildlife species or with an established resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites? (Less Than Significant) Wildlife corridors are described as pathways or habitat linkages that connect discrete areas of natura) open space otherwiseseparated or fragmented by topography, changes in vegetation, and ather natural or manmade obstacles such as urbanization. The project site is paved and is surrounded by dense residential and commercial development and does not connect areas of natural open space. Therefore, the project site is not part of an expected wildlife movement corridor. For these reasons, the proposed project would not substantially interfere with the local or regional movement of wildlife species and related impacts would be less than significant. e} Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? (Less Than Significant) The Gity of Burlingame defines a"protected tree" as any tree with a trunk circumference of 48 inches or more measured 54 inches above the ground. The City of Burlingame defines a"street tree" as any woody perennial plant that grows on City property (right-of-way). The proposed project requires the removal of four trees, all of which have a circumference of less than 48 inches and do not meet the definition of a"protected tree". Therefore, the proposed project would have no impact on protected trees. However, one of the trees to be removed is (ocated in the City right-of-way and is a City of Burlingame streettree. 7he proposed project includes planting seven City of Burlingame street trees. Additionally in compliance with the Burlingame ---- -" Municipal Code 11:04.035, prior to removal of any street tree, the project applicant would be required to obtain a permit from the City Arborist. With adherence to such policies and replanting efforts, the impact would be less than significant and no mitigation is required. 22 IniUal Study 988 Howard Avenue fj Conflict with the provisions of an adopted Habitat Conservation Plan, Natura( Conservation Community Plan, or other approved local, Regional, or state habitat Conservation plan? (No Impact) The site is not part of or near an existing Habitat Conservation Plan or Natural Communities Conservation Plan or any other local, regional, or state habitat conservation plan. Therefore, the proposed project would not conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat consenration plan. Therefore, no impact would occur. 23 Initiat Study Issues (and Supporting !»formoUon SourcuJ: s.

The results of this recards search are discussed below and included as Appendix D. A number of archaeological sites, Native American culturat resources, and paleontological resources have been discovered throughout San Mateo County. Given this, there is potential to uncover unrecorded buried cultural resources. The City of Burlingame does not contain buildings and structures that appear to be eligible for listing in the California Register of Historical Resources (CRHR) or the National Register of Historic Places (NRHP). Discussion a) Cause a substantial adverse change in the significance of a historical resource as defined in §15064.5? (No Impactj There are 23 structures within the Burlingame Downtown Specific Plan area that were identi�ed as potentially eligible for the CRHP and the NRHP. In addition, there are 51 structures within the downtown area that convey � -- --- -—certain aspects of Burlingame's histary and heritage, �ut are nat eligibla for the CftHR and PlRHP. Ho�r2v2r, none of these potentially historic resources are on the project site. Acco�ding to the CHRIS records search, no recorded buildings or structures are located within or immediately adjacent to the project site. Therefore, implementation of the project would have no impact on a historical resource. 24 Initial Study 988 Howard Avenue b) Cause a substantial adverse change in the significance of a unique archaeological resource pursuant to §15QG4.5? (Less Than Significant with Mitigation Incorporated} Native American cultural resaurces have been found within San Mateo County, but none have been identified within the project area. The CHRIS records search stated there is a low potential for unrecorded Native American resources in the project area, as well as low potential for un�ecorded histaric-period archaeological resources. Moreover, because the project site is fully developed, construction of the projecc would occur in an area that has been subject to deep subsurface disturbance for over 80 years. Therefore, implementation of the project is anticipated to have no effect on a known unique archaeologica) resource. However, there is a potential ta discover unidentified cultural resources during construction activities. This is considered a potentially significant impact. Implementation of the mitigation measures below would reduce this potentially significant impact to less than significant. Mitigation Measure CUL-1: in the event archaeological resources are encountered during construction, work will be halted within 100 feet ot the discovered materials and workers will avoid altering the materials and their context until a qualified professional archaeologist has evaluated the situation and provided appropriate recommendations. If an archaeologlcal site is encountered in any stage of development, a qualified archeologist will be consulted to determine whether the resource qualifies as an historical resource or a unique archaeological resource. In the event that it does qualify, the archaeologist will prepare a research design and archaeological data recovery plan to be implemented prior to or during site construction. The archaeologist shall also prepare a written report ofthe �nding, file it with the appropriate agency, and arrange for curation of recovered materials. c) Directly or indirectty destroy a unique paleontological resource or site or unique geologic feature? (Less Than Significant with Mitigation Incorporatedj No known paleontological resources have been recorded at the project site or within the vicinity; the nearest known fossi!-bearing site is located at least 4 miles removed. Further, the site is fully developed. A gas station and auto repair maintenance shop currently occupy the site; the gas station is not operational and has been inactive for approximately two years, but the associated underground storage tank remain. Given the lack of known resources and that the fully-developed site has been previously disturbed, the probability of encountering paleontological resources is low. However, construction activities could potentially destroy unknown paleontological resources. This is considered a potentially significant impact. In the event that paleontological resources are discovered during site development, implementation of Mitigation Measure - -- CUL-2 would mitigate this potentially significant impact to less-than-significant level. Mitigation Measure CUL-2: A discovery of a paleontological specimen during any phase of the project shall result in a work stoppage in the vicinity of the find until it can be evaluated by a professional paleontologist. Should loss or damage be detected, additional protective measures or further action (e.g., resource removal), as determined by a professionat paleontologist, shall be implemented to mitlgate the impact. 25 Initial Study 988 Howard Avenue dj Disturb any human remains, including those interred outside of formal cemeteries? (less Than Significant with Mitigation Incorporated) It is possible that unmarked burials may be unearthed during project construction. This is considered a potentially significant impact. If human remains are uncovered, the project applicant would comply with the Califomia Health and Safety Code Section 7050.5 regarding human remains, and the California Public Resources Code Section 5097.98 regarding the treaiment of Native American human remains. As a result, implementation of Mitigation Measure CUL3 would reduce the potential impact to less than significant. Mitigation Measure CUL-3: in the event that human remains are discovered during project construction, there shall be no further excavation or disturbance of the site or any nearby area reasonably suspected to overlie adjacent human remains. The county coronershall be informed to evaluate the nature of the remains.

The eay Area is considered one of the most seismically active areas in the country and is subject to the effects of future earthquakes. The majority of Burlingame (except for the northwestern portion) is essentially fiat (less than 1 percent slopej and is underlain by geologic materials consisting mostly of dense clay and clayey sand alluvial fan deposits dating 1.6 million to 10,000 years. These soils tend toward general stability and have a low infiltration rate (less than 0.2 inches per hour). 27 Initial5tudy 988 Howard Avenue Qualified geotechnical engineers recently completed a geotechnical investigation for a project located at 225 California Drive, which is within less than a 0.1 mile radius. Due to the ciose proximity to that site and the project site, the findings of the investigation related to regionai setting, site conditions and geotogic hazards are assumed to be similar and that report was used to prepare this section (Appendix E). Discussian aj Expose people or structures to potential substantial adverse effects, including the risk of loss, injury, or death involving: i. Rupture of a known earthquake fault, as delineated on ihe most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geotogist for the a�ea or based on other substantial evidence of a known fauit? Refer to Division of Mines and Geology Special Publication 42. (No impact} The following four historically active faults are located within 15.5 miles of the project site: ■ San Andreas Fault (approximately 2.9 miles west) • San Gregorio Fault (approximately 9.9 miles northeast) ■ Monte Vista-Shannon Fault (approximately 10.9 miles southeast) ■ Hayward (Total Length) Fault (approximately �5.5 miles east) The Alquist-Priolo Earthquake Fault Zoning Act (1972) and the Seismic Hazards Mapping Act (1990j direct the State Geologist to delineate regulatory zones to assist cities and counties in preventing the construction of buildings used for human occupancy on the surface trace of active faults. According to the California Department of Conseruation, the project site is not located within an Alquist-Priolo Earthquake Fauft Zone, nor is Burlingame affected byAlquist-Priolo Earthquake Fault 2ones. Additionally, no known surface expression of fault traces cross the site. Therefore, no impact would occur. ii. Strong seismic ground shaking? (Less Than Significant with Mitigation Incorporatedj The City is in relative proximity to historically active faults; as such, there is potential for development within the sphere to be subject to strong seismic ground shaking, including the project site. The intensity of earthquake ground motions would depend on the characteristics of the generating fault, distance to the fault and rupture zone, earthquake magnitude, earthquake duration, and site-specific geologic conditions. The San Andreas Fault is the closest active fault to the project site, approximately 2.9 miles west. Earthquakes along --=-- -- -- this fault are characteristically very strang (iv�odified iviercalii Intensity VIII) and groundshaking of this intensity could result in heavy damage. Given this, implementation of the project would expose people and structures to strong seismic groundshaking if an earthquake were to occur in the area. This is a potentially significant impact. Adherence to Mitigation Measure GEO-1 would ensure maximum practicable protection available to users of the buildings and associated infrastructure and reduce this patential impact to a less-than-significant level. 28 Initial Study 988 Howard Avenue Mitigation Measure GEO-1: Project design and construction shall adhere to Title 18, Chapter 18 of the Burlingame Municipal Code, and demonstrate adherence to the latest seismic design parameters as required by the California Building Cotle including, but not limited to, anchorage, load combinations, and structure integrity. iii. Seismic-related ground failure, including liquefaction? (Less Than Significantj Because the project site is in a seismically active region, some potentiai forseismic-related ground failure exists. The project site is flat and is underlain predominately by stiff to very stiff clays and medium dense to dense sands. Given this, the potentiai for significant seismic settiement is low. The Association of Bay Area Governments mapped the project site as having low potential for liquefaction. Additionally, an analysis perFormed by geotechnical enginee�s (see Appendix E) concluded low potential for liquefaction to affect the site. Therefare, the impact would be less than significant. iv. Landslides? (No Impact) The downtown area of Burtingame expe�iences a grade change of approximately 15 feet (less than 1 percent slopej. The area is relatively flat, without steep or unstable slopes, and does not have an irregular surface. As such, natural slope instability does not affect the project site. Landslides are not considered a hazard in the area. Therefore, no impact would occur. b) Would the project result in substantial soil erosien or the loss of topsoil? jLess Than Signiflcant) The project site is developed and is occupied with a gas station and auto repair maintenance shop. The existing building and asphalt would be demolished and removed as part of the project. Construction activities would be required to comply with the provisions in Appendix J of the California Building Code (CBC) (2007) in regards to grading, excavating, and earthwork construction. Soil erosion after construction would be controlled by implementation of approved landscape and irrigation plans, as needed. Additionally, the building footprint would cover approximately 73 percent of the lot (11,160 sf of the 15,352 sf lot) with the rest of the site mostly paved or landscaped. Therefore, there would be little exposed soil on site that would contribute to soil erosion effects. Further, conformance to the City grading standards and the county Stormwater Management Plan would prevent substantial erosion as a result of construction and implementation associated with the project. Therefore, the impact would be less than significant. c) ee located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially resutt in on or off-site landslide, latera! spreading, subsidence, - -.--- �--- -- liquefaction or collapse? (Less Than Significant �•rith Pllitiga;ion In;.or�crated) and d) Be located on expansive soil, as defined in Table 18-ib of the Uniform Building Code (1994), creating substantial risks to life or property? (Less Than Significant with Mitigation Incorporated) 29 Initial Study 988 Howard Avenue As previously discussed, the project site is not located in an area with high susceptibility to landslide effects or liquefaction owing to its flat topography. The geotechnical report determined the potential for lateral spreading to be low. While the soil is adequate to support the proposed infrastructure, geotechnical engineers recently measured ground water at a depth at 16.5 feet below grade, which could significantly impact excavation and other underground construction. Expansive soils typicaliy have a plasticity index (PIj of 15 orgreater. According to the geotechnical report, test results indicated a PI of 7 for surFace soils, which indicates a low expansion potential to wetting and drying cycles, and a PI of 16 for soils at a depth of 9.5 feet, which indicates medium swelling potential. This is considered a significant impact. The following mitigation would reduce this impact to (ess than significant. Mitigation Measu�e GEO-2: Froject design and construction, including excavation activities, shall comply with Chapter 33 of the CBC, which specifies the safety requirements to be fulfilled for site work. This would include the prevention of subsidence or pavement or foundations caused by dewatering. Adherence must also be demonstrated to Chapter 18 of the CBC, which sets forth building construction standards including, but limited to, expansive soils. e) Adherence to Mitigation Measure GEO-2 would ensure maximum practicable protection available to users of the buildings and associated infrastructure and reduce impacts from expansive soils to a less-than-significant-level. Have soils incapable of adequately supporting the use of septic tanks of alternative wastewater disposal systems where sewers are not available for the disposal of wastewater? (No Impact) The project site would dispose of wastewater using existing wastewater infrastructure operated by the City of Burlingame. No asped of the project would entail any use of septic tanks or alternative wastewater disposal systems. Therefore, no impact would occur. 30 InfUal Study luues (and Supponing lnjormatfon Sources): �.

Gases that trap heat in the atmosphere, GHGs, regulate the earth's temperature. This phenomenon, known as the greenhouse effect, is responsible for maintaining a habitable climate. The most common GHGs are carbon dioxide (COZ) and water vapor but there are also several others, most importantly methane (CH4), nitrous oxide (N20j, hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6)• These are released into the earth's atmosphere through a variety of natural processes and human activities. Sources of GHGs are generally as follows: ■ CO� and N20 are byproducts of fossil fuel combustion ■ N20 is associated with agricultural operations such as fertilization of crops ■ CH4 is commonly created by off-gassing from agricultural practices �e.g., keeping livestock) and landfill operations ■ Chlorofluorocarbons {CFCsj were widely used as refrigerants, propellants, and cleaning solvents but their production has been stopped by international treaty ■ HFGs are now used as a substitute for CFCs in refrigeration and cooling ■ PFCs and sulfur hexafluoride emissions are commonly created by industries such as aluminum production and_semi-conductor manufacturing Each GHG has its own potency and effect upon the earth's energy balance. This is expressed in terms of a global warming potential (GWP), with C0� being assigned a value of 1 and sulfur hexafluaride being several orders af magnitude stronger with a GWR of 23,900. In GHG emission inventories, the weight of each gas is multiplied by its GWP and is measured in units of CO2 equivalents (COZe). 31 Initial Study 988 Noward Avenue An expanding body of scientific research supports the theory that global warming is currently affecting changes in weather patterns, average sea (evel, ocean acidification, chemical reaction rates, and precipitation �ates, and that it would increasingly do so in the future. The climate and several naturally occurring resources within California could be adversely affected by the ciimate change trend. Increased precipitation and sea level rise could increase coastal flaoding, saltwater intrusion, and degradation of wetlands. Mass migration and/or loss of plant and animal species couid also occur, Potential effects of global climate change that couid adversely affect human health inciude more extreme heat waves and heat-related stress; an increase in climate-sensitive diseases; more frequent and intense natural disasters such as flooding, hurricanes and drought; and increased levels of air pollution. The BAAQMD May 2017. CEQA Guidelines included GHG emissions-based significance thresholds. These thresholds include a"bright-line" emissions level of 1,100 metric tons per year for land-use type projects and 10,000 metric tons per year for stationary sources, Land use projects with emissions above the 1,100 metric ton per year threshold would then be subject to a GHG efficiency threshold of 4.6 metrictons per year per capita. Projects with emissions above the thresholds would be considered to have an impad, which, cumulatively, would besignificant. According to the Burlingame Downtown Specific Plan IS/MND, the City adopted the Burlingame Climate Action Plan in June 2009 with the goal reducing GHG emissions to 286,402 MT COZe by 2020.3 Although the Burlingame Climate Action Plan is not an established Climate Action Plan, the City also conforms to the state target for 2050 (emissions at 80 percent below 1990 levels) set forth in Executive Order (EO) 5-03-05. Additionally, EO B30-15 establishes an interim statewide GHG emission reduction target of 40 percent below 1990 levels by 2030. Additionally, the construction and operation of all new buildings in the City are required to comply with energy efficiency standards included in Title 24 of the California Code of Regulations. Title 24 identifies specific energy efficiency requirements for building construction and systems operations that are intended to ensure efficient energy usage over the long-term life of the building. Discussion a) Generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment? (Less Than Significant) GHG emissions associated with development of the proposed project would occur over the short-term from construction activities, consisting primarily of emissions from equipment exhaust and warker and vendortrips. There would also be long-term operational emissions associated with vehlcular traffic within the project _- ___. __,__ vicinity, energy and water usage, and solid waste disposal. Emissions for the proposed project are discussed below and were analyzed using the methodology recommended in the BAAQMD CEQA Air Quality Guidelines. Construction ProJect constructlon activities are predicted to generate 108 MT of COze using the conservative "default" construction scenario outlined in Section 3, Air Quality. Neither BAAQMD nor the City has an adopted 3 Downtown Burlingame Specific Plan IS/MND, May 201D, 32 Initial Study 988 Howard Avenue threshold of significance for constructian-related GNG emissions and project construction emissions would be below the BAAQMD operational significance threshold of 1,100 MT of CO�e annually. Using this threshold, the projecYs impact is considered less than significant. However, BAAQMD encourages the incnrporation of best management practices to reduce GHG emissions during construction where feasible and appiicable. Best management prac�ices may include, but are not limited to; using alternative fueled {e.g., biodiesel, electric) canstruction vehicles/equipment for at Ieast 15 percent of the fleet; using at least 1D percent local building materials; and recycling or reusing at Ieast 50 percent of construction waste or demolition materials (see Mitigation Measure AQ-1}. Mitigation Measures AQ-1 and AQ-2 would reduce construction-related impacts to a less than significant level. Operation Due to the project size, operational periad GHG emissions would be lessthan significant. BAAQMD identified screening criteria forthe sizes of land use projects that could result in significant GHG emissions in their May 2011 update to the CEQA Air Quality Guidelines. For operationa) impacts, the screening projectsize is identified at 53,000 sf for commercial land uses. Mixed use development projects of smaller size would be expected to have (ess-than-significant impacts with respect to operational period GHG emissions. Since the project proposes to operate 22,295 sf of office space and 1,325 sf of retail, it is concluded that emissions would be below the BAAQMD significance threshold of 1,100 MT of COZe annually. Impacts associated with the generation of greenhouse gas emissions, directly or indirectly, wouid be less than significant with project implementation. b) Conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing the emissions of greenhouse gases? (Less Than Significant) As stated above, the project would be subject to the most recent requirements under rule making developed at the state and local level regarding greenhouse gas emissions and would be subject to local policies that may affect emissions of greenhouse gases. Therefore, project implementation would not conflict with an applicable plan, policy, or regulation adopted for the purpose of reducing the emissions of GHGs, and any impacts would be less than significant. 33 Inidal Study lssees (and Suppoeiiny lnformatlon SourcesJ: s.

A Phase I Environmental Site Assessment (ESA) was prepared by Green Environment, Inc. (GEIj in September 2014 to identify and evaluate the potential hazardous materials on and in the project 34 Initial Study 988 Howard Avenue vicinity. Due to the historic and present use of the project site a Phase fl ESA was also conducted to evaluate the subsurface soil and groundwater conditions and to examine any potential impacts resulting from the past use and storage of petroleum hydrocarbons orother chemical substances (see Appendix F). The existing buildings were constructed between 1959 and 1978 and have the potentia) to contain asbestos and lead-based paint. Health hazards associated with asbestos include increased risks of cancer and respiratory-related illnesses and diseases, while lead may cause a range of health effects, including behavioral problems, learning disabilities, seizures and death. Exposure to groundwater contamination, asbestos, and lead-based paint during construction and demolition activities could resuit in a potentially significant hazard to human health unless properly mitigated. Discussion a) Create a significant hazard to the public or the environment through the routine transport, use, or disposat of hazardous materials? (Less Than Significant) The project applicant is propqsing office and retail land uses at the project site. Common chemicals used for such land uses include cleaners, toners, correction fluid, paints, and maintenance materials. Use ofthese types of products and chemical would not invalve substantial use, transport, and disposal of hazardous materials. During construction, paint, building material finishing products, and automotive oil would be used as well. However, such materials are used temporarily and typically do not generate hazardous air emissions or pose a (ong-term threat to human health orthe environment. The project would remove approximately 6,000 cubic yards of soil, which would be disposed of at the appropriate facility. Contaminated soil would be sent to either Ox Mountain (Half Moon Bay) or Dumbarton Quarry (Newarkj, as autlined in the Soils Management Plan (SMP) described in Mitigation Measure HAZ-3 below. Improper disposal could fncrease risk of exposure for nearby residents through direct contact or by adversely affecting soil, groundwater, or other surface waters on and around the site. Mitigation Measure HAZ-4 would ensure proper disposal methods for such resources. Hazardous materials transportation, use, and disposal, as part of the project, would be subject to state and federal hazardous materials laws and regulations. Additionally, the project would comply with hazardous materials policies in the Burlingame Downtown Specific P(an IS/MND. With adherence to local, state, and federal regulation regarding the transport, use, and disposal of hazardous materials, the project would have a less-than-significant impact. bj Create a significant hazard to the public or the environment through reasonably foreseeable upset ,.-. __--_ __ .. -____ _,. and accident conditions involving thQ relerss Qf ha:ar�+ass materials inta th� envirortm�stt? (Less Than Significant with Mitigation Incorporated) The project site is currently developed with a gas station, and an automobile repair business. According to the Phase I ESA, hazardous material use and storage on the project site includes the retail dispensing of gasoline and diesel fuel from underground storage tank via fuel pumps, the use and storage of motor and transmission oils, lubes, greases, antifreeze, Freon, solvents, and lead-acid batteries for automobile repair and service, as well aa potential risk from halogenated volatile organic compounds from an unidentified local area plume. The Phase I report determined that 32 Leaking Underground Storage Tank (LUST) sites are located within 0.5 miles of the project site, and concluded that only 1 of these sites has the potentia) to impact the project site. The 35 initial Study 988 Howard Avenue LUST and 5pills, Leaks, investigations, and Cleanups (SLIC) sites are located at Z15 California Drive, approximately 600 feet southwest from the project site. As described ebove, a Phase 11 ESA was conducted to sample the soil and groundwater at the project site for potential hazardous substances. Based on the Phase il ESA, the soil sample and soii vapor results contain Petroleum Hydrocarbons (TPH), Volatile Organic Compounds (VOCj, and Heavy Metals. However, these levels were determined to be below the environmental screening levels (ESLj published by the RWQCB's Screening for EnvJronmental Concems ot Sites with Contaminated Soil and Groundwater. As a result, exposure to these soi[ contaminants is nat expected tn cause a significant impact to human health during construction and operation of the project. The Phase II also collected groundwater samples at the project site and the samples showed that the TPHmo result of 1,000 µg/L and the methyl tert butyl ethe� (MTBE) result of 28 µg/L (recovered at32 ft below grade) exceeded the thresholds for potable drinking water resource protection. Furthermore, the TPHmo result also exceeded the threshold for non-potable water resources. Operation The project would connect ta the existing municipal services, which would not use the extraction of groundwater for water supply. The San Mateo Health Department was consulted regarding the groundwater contamination and indicated that the groundwater contamination is not a concern for project implementation. The project proposes to construct an office building on the project site; after construction, employees and guests operating from the new building would not come into contact with any contaminated soils/groundwater. Construction As described above, reported groundwater contamination at the proJect site was found to be at approximately 32 feet below ground surFace. Construction workers are not anticipated to come into contact with groundwater because project excavation would reach approximately 12 feet. Additionally, construction workers could potentially be exposed to asbestos and lead-based products during the demolition/construction activities. Although construction workers are not expected to come into cantact with subsurface contaminants, the San Mateo County Health Department requires that aSoils Management Pfan (SMP) 6e submitted fortheir approval prior to issuance of a building permit (Mitigation Measure HAZ3�. The SMP shall address the possibility of encountering subsurface contaminants, including groundwater, during construction activities, and the relevant measures for identifying, handling, and disposing of subsurface contaminants. Furthermore, implementation of the Title 8, California Code of Regulations/Occupationa) Safety and Health --- --- -_(OSHA) requirements, outlined in E".it:b�:i�n M��su: �s HAZ-! and HA?-6 betow would reduce the potential hazard with asbestos and lead-based paint to a less-than-significant level. lmplementation of Mitigation Measures HAZ-1 through HAZ-6 would reduce the impacts associated with demolition and construction to a less-than-significant level. 36 IniUal Study Mitigatian Measure HAZ-1. The contractor shall comply with Title 8, California Code of 988 Howard Avenue Regulations/Occupational Safety and Health (OSHA) requirements that cover construction work where an employee may be exposed to lead. This includes the proper removal and disposal of peeling paint, and appropriate sampling of painted building surfaces for lead prior to disturbance of the paint and disposal of the paint or painted materials. Mitigation Measure HAZ-2. The applicant shall contract a Certified Asbestos Consultant to conduct an asbestos survey prior to disturbing potential asbestos containing buiiding materials and shall implement the Consultant's recommendations for proper handling and disposal. Mitigation Measure HAZ-3. The applicant shall prepare, and submit, a Soils Management Plan (SMP) to the San Mateo County Health Department for approval, priorto the issuance of a building permit. The SMP shall address the possibility of encountering subsurface contaminants, including groundwater, during construction activities, and the relevant measures for identifying, handling, and disposing of subsurface contaminants: ?he SMP shall be submitted to the City priorta issuance of a building permit. Mitigation Measure HAZ�4. The contractor shall ensure #he appropriate handling, storing, and sampling of any soil to be removed fromthe subject property, as perthe SMP, so as to eliminate potential health ancf safety risks ta the public, including construction workers. Mitigation Measure HAZ-5. In the event that g�oundwater, or other subsurface contaminants, are encountered during excavation, grading, or any other demolition/construction activities at the project site, the contractor shall ensure that the procedure for evaluating, handling, storing, testing, and disposing of contaminated groundwater is implemented, as per the SMP (see Mitigation Measure HAZ-3). Mitigation Measure HAZ-6. Workers handling demolition and renovation activities at the project site shall be trained in the safe handling and disposal of residual chemicals, solvents, heavy metals, motor and transmission oils, lubes, greases, antifreeze, Freon, solvents, and lead-acid batteries etc. associated with the former gas station and auto repair maintenance shop. With implementation of Mitigation Measures HAZ 1 through HAZ-6, impacts associated with hazard to the public orthe environment through reasanably foreseeable upset and accident conditions involving the release of hazardous materials into the environment would be less than significant. c} Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? (Less Than Significant) _ --- __ _ _.__..--_ . _.. Washington Elementary School, located approximately 0.1 miles east of the property, is the only school within 0.25 miles of the project site (see Figure 1). As stated above, hazardous materia) use and storage on the project site includes the retail dispensing of gasoline and diesel fuel from underground storage tank via fuel pumps, the use and storage of motor and transmission oils, lubes, greases, antifreeze, Freon, solvents, and lead-acid batteries for automobile repair and service, as well contaminated soil and groundwater from an unidentified plume in the project vicinity. Additionally, during constructian, the project could involve the handling, and disposal, of hazardous was#e products, such as asbestos and lead. Most of the above-mentioned substances are typically found within commercial sites. Handling of such substances from the site would be 37 Initiai Study 988 Howard Avenue regulated by state and federal hazardous material laws, including the Resource Conservation and Recovery Act, The Hazardous Materials Transportation Act, State Water Code, Undergraund Storage Tank Code, Cortese Act (listing of hazardous waste and substances sites), and Praposition 65 (safe drinking water and toxics enforcementJ; all of which would minimize the risk of exposure to nearby land uses, induding Washington Elementary. Additionally, implementation of Mitigation Measures HAZ-1 through HAZ-6 would further reduce potential impacts to risk of exposure to nearby land uses. As stated above, the project would inciude office and retail �and uses on the project site. Common chemicals used in commercial and office settings include cleaners, toners, correction fluid, paints, and maintenance materials. Use of these types of products and chemicais would not emit hazardous emissions or require the handling hazardous or acutely hazardous materials. For these reasons, the project would have a less-than- significant impact to schools with 0.25 mile of project site. d) Be located on a site which is included on a list of hazardous ma#erials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard ta the public or the environment? (No Impactj The State of California Hazardous Waste and Substances Site List (also known as the "Cortese List") is a planning document used by state and local agencies and developers to comply with CEQA requirements in providing information about the location of hazardous materials sites. According to the Department of Toxic Substances Control, the project site is not currently listed on the'Cortese' list pursuant to Government Code Section 659b2.5. Therefore, the project would have no impact. e) For a project located within an airport land use plan or, where such a plan has not heen adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard for people residing or working in the project area? (No Impact) San Francisco International Airport (SFO) is approximately 2 miles north of the project site. According to the Burlingame Downtown Specific Plan IS/MND, the project site is within the 19965an Mateo Comprehensive Airport Land Use Plan (ALUP)°. The ALUP is subject to land use policies and restrictions, which includes a 300 feet height restriction associated with Federal Aviation Administration (FAA} regulations. The proposed project includes the construction of a three story, 45-foot, office building. Given that the height of the building is belaw the 300-foot height restriction, there are no anticipated safety hazards to people residing or working in the project area as a result of p�oject implementation. Therefore, no impact would occur. f� Ecr a project within the vicinity of a private airstrip, would the project result in a safety hazard for people residing or working in the project area? (No Impactj There are no private airstrips within the project vicinity. Therefore, there would be no safety hazards to people residing or working in the project area as they pertain to private airstrips and no impact wauld occur. 4 Burlingame Downtown Specific Plan, 2030.

(No Impact) The project would build the new structure on previously developed commercial land. Access paints to the site would be constructed to ensure proper access for emergency vehicles. Therefore, the project would not conflict with an adopted emergency response or evacuation pian and no impact would occur. h) Expose people or structures to a significant risk of loss, injury or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands? (No Impact) The praject site and the surrounding vicinity are entirely developed. The area does not contain, and is not adjacent to wiidlands. Accordingly, implementation of the project would not resuit in the exposure of people or structures to significant loss, inJury, or death involving wiidland fires and no impact would occur. 39 Ini6al Study BI h� ij J) 988 Howard Avenue tess Thon Sign�cont or Slgnljlcant PotenHalfy with Less Than S/gnificont MI2lqaGon Slgnificant lssuesfandSuppardnglnformationSourtesJ: /mpact ltttorpo�atioe Impact Nolmpact s.

These agencies oversee the implementation of the National Poliutant Discharge Elimination System (NPDES) stormwater discfiarge permits. The SWRCB has imptemented a NPDES Genera) Cvnstruction Permit for the State of California for projects disturbing 1 or more of acres of soil. Construdion activity subject to this permit includes clearing, grading, and disturbances to the ground such as stockpiling or excavation. Dischargers are required to obtain coverage under the General Permit and are required to file a Notice of Intent (NOI) and prepare a stormwater pollution prevention plan (SWPPP) priorto commencement of construction. The City participates in the San Mateo Countywide Pollution Prevention Program (STOPPP), 40 Initial Study 988 Howard Avenue end is required to implement Low impact pevelopment (LID) BMPs under Municipai Regional Stormwater Permit (MRPj(Provision C.3.b.). LID practices include source cantrol BMPs, site design BMPs, and stormwater treatment BMPs onsite or at a joint stormwater treatment facility. eurlingame Water Division of the Public Works Department, which purchases treated water from the San Francisco Public Utilities Commission, provides potable water to the project site. Approximately 85 percent of the water supply comes from the Hetch Hetchy watershed in the 5ierra Nevada Mountains and approximately 15 percent comes from local watersheds. The project area does not contain any natural surface drainage. Stormwater runoff is entirely contained within a storm drainage system that utilizes Burlingame Creek, Ralston Creek, and Ter�ace Creek fo� drainage purposes. The project site does not include any surface waters; the nearest bodyof surface water to the subject property is the San Francisco Bay, located approximately 1 mile east of the project site. Groundwater was encountered intermittently during the Phase II ESA testing at app�oximately 32 feet below ground surface (see Appendix F). According to the Federal Eme�gency Management Agency (FEMAj Flood Insurance Rate Map (FIRMj, the project site is located within Zone 6, which is an area subject to inundation by a 0.2 percent annual chance flood event. Discussion a) Violate any water quality standards or waste discharge requirements? (Less Than Significant) Construction of the new building would involve ground disturbing activities such as trenching, grading, demolition, and vegetation removal. The maximum depth of these activities would be approximately 12 feet below ground surface. Groundwater is approximately 32 feet below ground surface and would therefore not be encountered during construction activities. Construction activlties also have the potential to result in runoff that contains sediment and other pollutants that could degrade water quality if not properly controlted. Sources of pollution associated with construction include chemical substances from construction materials and hazardous or toxic materials, such as fuels. As stated above, over 1 acre of soil would be disturbed during construction; therefore, the project would be subject to a State NPDES General Construction Permit which would require submittal of a N01 to the SWRCB. Erosion control requirements are stipulated in the NPDES Permit issued by the RWQCB. These requirements include the preparation and implementation of a SWPPP that contains BMPS. The purpose of the SWPPP is to identify potential sediment sources and other pollutants and prescribe BMPs to ensure that potential adverse erosion, siltation, and contamination impacts would not occur during construction activities. Implementation of a SWPPP with BMPs would contro) erosion and protect water quality from potential contaminants in stormwater runoff emanating from the construction site. BMPs may include damp street sweeping, providing appropriate covers, drains, and storage precautions for outdoor material storage areas, temporary cover of dIstu�bed surfaces, etc., which would help to protect water quality. Once operational, the project site would generate wastewater associated with office and retail land uses. Such land uses do not contribute significant amounts of pollutants that would violate water quality standards or waste disCharge requirements. Therefore, impacts associated with water quality standards and wastewater discharge requirements would be less than significant. 41 Initial Study 988 Howard Avenue b) Substantially deplete groundwater supplies or interfere substantially with groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the local groundwater table level (e.g., the production rate of pre-existing nearby wells would drop to a level which wouid not support existing land uses or planned uses for which permits have been granted)? (No impact) The project site is fully paved and developed and does not directly contribute to groundwater recharge. The groundwater basin in the existing project site is not currently utilized for potable water. The project does not include plans to use groundwater resources for future uses. The project would not substantially deplete groundwater as there is no plan to create water wells on the site and the future land users on the site would receive municipa) water from the City of Burlingame Water Division of Public Works. Therefore, no impact would occur. c� Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, in a manner which would result in substantial erosion of siltation on- or off-5ite? (less Than Signlficant) and d) Substantially alter the existing drainage pattern of the site or area, including through the alteretion of the course of a stream or river, or substantially increase the rate or amount of surface runoff in a manner which would result in flooding on-or off-site? ( Less Than Significant) There are no natural drainage features on or near the project site. The existing drainage pattern entails the use of (ined channels, culverts, and underground pipes, all of which eventually drain into the San Francisco Bay. Project construction would involve ground disturbing activities. As noted above under item 9a, project construction would be subject to the NPDES General Construction Permit that imposes strict requirements and control on construttion and post-construdion activities. Furthermore, the site is currently developed with areas of impervious pavement. Once operational, the amount of surface runoff generated by the project is not expected to increase compared to existing conditions and the new building would not significantly alter the quantity of impervious surfaces or the existing drainage patterns. No new water intensive activities are proposed that would cantribute substantial additional runoff that could exceed the capacity of stormwater drainage systems in the area. The Street and Sewe� Division of the Department of the City Pu61ic Works Department maintains Burlingame's stormwater infrastructure. The project site is connected to existing 15-inch stormwater lines and the new building would tie-in to these existing lines to convey stormwater infrastructure. Bio-swales for stormwater _., - _- - � . . _ treatrr�ent and drainage around the project site would be installed as well. Additionally, with compliance to state and local regulations, and the implementation of BMPs, impacts to drainage patterns and surface runoff, resulting in erosion or siltation would be minimized. As such, the project would not contribute substantial amounts of sediment to storm drain systems or alter existing drainage patterns to the extent that would result in flooding on-o� off-site. The impact would be less than significant. 42 Initiat Study 988 Haward Avenue e) Create or contribute runoff water which would exceed the capacity of existi�g or planned stormwater drainage systems or provide substantial additional sources of polluted runoff? (less Than Significant) and f) Otheruvise substantially degrade uvater quality? (Less Than Significant) As stated above in c), and d), the proposed project would not alter the existing impervious surFace to a point at which the drainage, and surface runoff, in the area would be affected. Standard Permit Conditions would require the project to Implement a SWPPP with BMPs during construction activities to protect water quality from potential contaminants in stormwater runoff emanating from the construction site. The project would also be subject to the requirements of Provision C.3 of the Municipal Regional Stormwater NPDES Permit. Use of the project site by motor vehicles would typically result in the deposit of various materials on the roadway and adjacent areas that constitute urban pollution as previously discussed. However, such vehicle use would nat be substantially greater than that under existing conditions, and no new significant sources of polluted runoff would be created. With compliance to state and local regulations, and the implementation of BMPs, impacts to surface runoff, resulting in additianal saurces of polluted runoff, or degradation to water quality, would be less than significant. g) Place housing within a 100-year fload hazard area as mapped an a federal Flood Hazard Boundary ar Flood Insurance Rate Map or other flood hazard delineation map7 (No Impact) and h) Place within a 100-year flood hazard area structures which would impede or redirett flood flows? (Na Impactj The project site is categorized by FEMA as Zone B(500-year floodplain}, which is an area subject to inundation by a 0,2 percent annuai chance fload event. The project indudes the canstruction of an office building, and as such, no housing would be constructed as a result af the project. Therefore, na impact wauld occur. i) Expose people or structures to a significant risk of loss, injury ar death irnolving flooding, including flooding as a result of the failure of a levee or dam? jless Than Significant) The closest dam to the project site is Crystal Springs Dam, located approximately 5 miles southwest of the project site. Due to the dam's distance from the project site, it does not pose extensive safety hazards to the ___.. project; the 5-mile distance would significantly reduce the velocity of moving water, and consequently any possible impacts in the unforeseen incidence of dam failure would not expose people or structures within the project vicinity to a significant risk of loss, injury, or death, Additionally, the dam is currently undergoing 43 initial Study 988 Howard Avenue renovations to enhance the safety of the structure in the event of a major earthquakes. Implementation of the project would not signi�cantly change the existing conditions and expase people or structures to significant risk due to failure of a levee ar a dam. Therefore, the impacts due to development in Flood Hazard Areas would be less than significant. jj Inundation of seiche, tsunami, or mudflow? (Less Than Significantj Tsunamis are large ocean waves generated by earthquakes and can be damaging to lowland coastaf areas. The project site is approximately 10 miles away from the Pacific coast, and the risk of damage due to a tsunami is low. According to the Burlingame Downtown Specific Plan IS/MND, downtown Burlingame is located 25 feet above sea level, and any large wave would have dissipated to less than 18 feet by the time it reaches the City. Large earthquakes can afso generate oscillating waves in enclosed bodies of water (seiche), such as bays, lakes and reservoirs. The project site is located approximately 1 mile west of the San Francisco Bay, and 3 miles northeast of Crystal Springs Reservoir (at its closest point), and 5 miles northea5t of the Crystal Springs Dam. Since the project site is not located in the immediate vicinity of any bays, lakes, or reservoirs, the probability of a seiche from either the San Francisco Bay, or the Crystal Springs Reservoir, or dam, having enough momenium to affect the property site is low. Furthermore, as no steep slopes are located in close proximity ta the project site, the possibility of inundation by landslides or mudflows would be remote. Therefore, the impact would be less than significant. 5 County of San Mateo Public Works.2015. Crystal Springs Dam Bridge Replacement Project.

Burlingame is divided into a series of planning areas. According to the Burlingame Downtown Specific Plan IS/MND, the project site and adjacent parcels are within the Myrtle Road Mixed Use (MMU) planning area. The land use designation for MMU is mixed use retail/residential. The land use designation allows for a variety ofsmall commercial, residential, and retail uses. The area is meant to serve as a buffer between the downtown commercial district and the residential neighborhoods to the east. The downtown area contains a variety of land uses, including commercial, office, cultural, civic, and quasi-civic. Discussion a) Physically divide an established community? (No Impact) As previously discussed, the project site is currently developed with commercial land uses within an existing neighborhood. The project would redevelop the site lnto retail and office uses. Given this, implementation of the project would not result in physical division of an established community into two or more areas. Therefore, no impact would occur. b) Conflict with any applicable land use plan, policy, or regulation of an agency with jurisdiction over the .__ __ project (including, but not limited to the general plan, specific plan, loea) coasta! prog�am, or zoning ordinance) adopted for the purpose of avoiding or mitigating an environmental effect? (No Impactj The project site is governed by the General Plan, Burlingame Downtown Specific Plan, and the Burlingame Municipal Code (BMC). According to the Burlingame Downtown Specific Plan IS/MND, the project site and adjacent parcels are designated MMU, which supports retail and office uses. The project would redevelop a vacant commercial property and construct a building with a mix of retail and cammercial uses, which is consistent with Chapter25.34 MMU District Regulations of the BMC, The�efore, the projed would not conflict with any land use plans or policies, and no impact would occur. 45 Inidal Study 988 Howard Avenue c) Conflict with any applicable conservation plan or natural community conservation plan? jNo Impactj According to the Burlingame Downtown Specific Plan IS/MND, the site is not part of or near an existing Habitat Conservation Plan or Natural Communities Conservation Plan or any other local, regional, or state habitat conservation plan. Therefore, the proposed project would not conflict with the provisions of an adopted Habitat Conservation Pian, Natural Community Conservation Plan, orother approved locai, regional, arstate habitat conservation plan.

Additionally, a survey of existing commercial uses in the vicinity of the project site revealed that occasional car washes and servicing at the auto dealership to the northwest are temporary stationary noise sources affecting the site. 48 initial SWdy 988 Howard Avenue A noise monitoring survey was done to quantify ambient noise levels at representative noise-sensitive locations adjacent to the project site. The survey was conducted August 4 to 6, 2015, and included two short- term measurements (ST-1 and ST-2), and two long-term measurements (LT-1 and LT-2j, taken throughout the project site as summarized in Tabie 4.

Additionally, the General Plan established recommended noise emission standards for cnnstruction equipment operating within the City (see Appendix G), and states that no construction noise can be emitted past the property line so as to create a noise leve! increase of more than 5 dBA Lmax above ambient lm,� noise levels. A�lowable hours of construction within the City are between 7:00 am and 7:00 pm on weekdays, 9:00 am and 6:00 pm on Saturdays, and 10:00 am and 6:00 pm on Sundays and holidays, as established by the Burlingame Municipal Code Section 18.07.110. _-_ Discussion a) Expose persons to or generate noise levels in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? (Less Than Significant with Mitigation Incorporatedj Project construction is expected to last 12 to 18 months, and would occur between the hours designated by the General Plan. The development of the project is expected to generate noise, and would temporarily increase noise levels at nearby sensitive land uses. Project construction activities that are expected to impact noise levels within the project vicinity include demolition, site preparation, grading/excavation, trenching, 49 Initial Study 988 Howard Avenue exterior/int�rior building, and paving- all of which utilize heavy construction equipment. Construction activities would intermittently exceed the threshold at noise sensitive receivers to the north and northeast. The following Best Management Practices (BMPs) would reduce construction noise impacts to a less-than- significant level: ■ Noise-generating activities at the construction site or in areas adjacent to the construction site associated with the project in any way would be restricted to the hours of 7:00 am to 7:00 pm, Monday through Friday, and 9:00 am to 6:0� pm on Saturdays, and 10:00 am to 6:00 pm on Sundays and holidays. All internal combustion engine driven equipment would be equipped with intake and exhaust mufflers which are in good condition and appropriate forthe equipment. ■ Stationary noise generating equipment (e.g., concrete crushe�j would be located as far as possible from sensitive receptors, and acoustically shielded with temporary noise barriers, material stockpiles, etc. to reduce noise levels at nearby residences. ■"Quiet" air compressors and other stationery noise sources would be utilized where technology exists. ■ The contractor would prepare a detailed construction plan identifying the schedule for major noise- generating construction activities. This plan shall be distributed to noise-sensitive uses within 1,200 feet of the project site. ■ A"disturbance coordinator° would be designated, and would be responsible f�r 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 as soon as possible. A telephone number for the disturbance coordinator should be posted at the construction site and included in the notices sent to neighbors regarding the construction schedule. The project would increase noise on- and off-site from existing conditions; the project would place future users in an environment that exceeds the standard for the type of land use proposed. The future noise environment at #he project site would continue to result primarily from local transportation, and Caltrain railroad noise within the project vicinity. According to the noise analysis performed for the project, the future exterior noise exposure is calculated to be up to 77 dBA CNEL, which exceeds the Cit�s standard of 65 dBA CNEL. These noise levels at the roof top deck would be reduced by more than 15 dBA as a result of shielding by #he proposed building, parapet walls surrounding the deck, and because of increased distance from the western border of the project. Therefore, exterior operatianal noise sources associated with the project would be reduced to less than 62 dBA, and would not cause a substantial increase in ambient noise levels a6ove existing -- - con itions:— -- With regard to interior noise levels, due to vehicle traffic and the close proximity of the Caltrain, the future users at the site could potentially experience noise levels ranging from 6b dBA CNEL to 73 dBA CNEL LeQ(1-hr), which would exceed interior noise and land use compatibility standards. The State of California's wall and roof-ceiling assemblies exposed to adjacent roadways Sound Transmission Class (STC} rating of at least 50 or a �a Inifial Study 988 Howard Avenue composite Outdoor-IndoorTransmission Class (OITC) rating of no less than 40 would provide at least 35 to 40 dBA of noise reduction in interior spaces. Additionally, the inclusion of adequate forced-air mechanical ventilation systems is normally required so windows may be kept closed at the occupant's discretion. The sound-rated construction materials established in the California Building Cal Green Code in combination with forced-air mechanical ventilation would satisfy the threshold. However, this is a potentially significant impact that would be minimized to fess than significant with the following mitigation measures: Mitigation Measure NOI-1. The contractor shall ensure that the interior noise levels are ma intained at or below 50 dBA leQ�l-n��• Treatments would include, but are not limited to, sound-rated wall and window constructions, acoustical caulking, protected ventilation openings, etc. The specific determination of what noise insulation treatments are necessary shall be conducted on a room-by-room basis during final design of the project. Results ofthe analysis, including the description of the necessary noise contro) treatments, shall be submitted to the City, along with the building plans and approved design, prior to issuance of a building permit. Mitigation Measure NOI-2. The contractor shall install forced-air mechanical ventilation, as determined by the local building official, for all exterior-facing rooms of the office building so that windows can be kept closed at the occupant's discretion to control interior noise and achieve the interior noise standards. With implementation of the above BMPs, and Mitigation Measures NOI-1 and NOI-2, noise-related impacts that would expose people to interior noise levels above standards established by local and state policies would diminish, and noise levels associated with construction and operation of the project would be reduted to a less-than-significant level. b) Expose people to or generate excessive g�oundborne vibration or g�oundborne vibration levels? (Less Than Significant) The California Department of 7ransportation recommends a vibration limit of 0.5 Peak Particle velocity inches per second (in/sec PPV) for buildings that are structurally sound and designed to modern engineering standards; hawever, groundborne vibration levels exceeding 0.3 in/sec PPV could have the potential to result in significant vibration impacts. The construction of the project may generate perceptible vibration when heavy equipment or impact tools (e.g. jackhammers, hoe rams) are used, and construction activities such as demolition, site preparatian work, foundation work, new building framing and �nishing, and paving could result in perceptible groundborne vibration. Vibration levels would vary depending on soil conditions, construction methods, and equipment used (see Table 5). The nearest residential land uses would be - approximately�0 feet northeast the project siie across �vlyrtle Road. At this distance, vioration levels would be expected to be 0.06 in/sec PPV or less. All vibration levels expected at nearby residences would, therefore, be below the p.3 in/sec PPV significance threshold. As a result, any exposure of people to groundborne vibrations exceeding established standards would be less than significant. 51 Initial 5iudy Table 5 Vibration Source Levels for Constructian Equipment 988 Howard Avenue Equipment PPV at 25 ft(in/sec) Approximate L„ at25 ft(VdB)* Upper 1.158 112 Pile Driver (Impactj Range Typical 0.644 104 Upper 0.734 105 Pile Driver (Santc) Range Typical 0.170 93 Clam Shovel Drop 0.202 94 in Soil 0.008 66 Hydromill {slurrywall) 0.017 75 in Rock Vibratory Roller 0.230 94 Hoe Ram 0.089 87 Large Bulldozer 0.089 87 Caisson Drilling 0.089 87 Loaded trucks 0.076 86 Jackhammer 0.035 79 Small Bulidozer 0.003 58 Notes:'VdB—Ybration dedbels Lv— Vibration Level INsec — Inches per secand Source: IBingworth 8 Rodkin, 2015 c) Cause a substantial permanent increase in ambient noise levels In the project vicinity above levels existing without the project? (Less Than Significant) A significant impact woutd occur if the permanent noise level increase due to project-generated noise was 3 dBA Ld„ or greater for existing levels exceeding 60 dBA Ld„ or was 5 dBA Ldn or greater for existing levels at or below 60 dBA Ld,,. Ambient noise levels at the nearest receptors are above 60 dBA CNEL at times, and would exceed 60 dBA CNEL with the project; therefore, the 3 dBA CNEL or greater significance threshold would apply. A review of the Traffic Analysis Report prepared forthe project, concludes that the proposed project would not resuit in a net increase in the overall vehicle trip generation (see Section 16 and Appendix H). As a result the traffic noise generated by the project would be similar to existing conditions. Additionally, an enclosed parking lot would be located on the basement level. However, the entrance and exit would share the same driveway, accessed via East Lane along the western border of the project site. Noise-generating activities (vehicle circulation, engine starts, door slams, etc.) at the parking lot would generally coincide with activities in 52 initial Study 988 Howard Avenue the existing use at the site parking lot, and as a result, the proposed parking lot would not substantially increase ambient noise levels at the project site or in the surrounding vicinity. The project would not result in a permanent increase is ambient noise levels above those noise levels currently generated by existing conditions. d) Result in a substantia) temporary or periodic increase in ambient noise levels in the project vlcinity above le�els existing without the proJect? (Less Than Significant with Mitigation Incorporated) As stated above in a) and c), the development of the project is expected to generate noise, and would temporarily increase noise levels at nearby sensitive land uses. Project construction activities that are expected to impact noise levels within the project vicinity include demolition, site preparation, grading/excavation, trenching, exterior/interiar building, and paving- all of which utilize heavy construction equipment. Construction activities would intermittently exceed the threshold at noise sensitive receivers to the north and northeast. This is considered a significant impact. With implementation of the BMPs stated above, and Mitigation Measures NOI-1 and IVOI-2, temporary increases in ambient noise levels in the projed vicinity would be reduced to a less-than-significant level. e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? (Less Than Significantj SFO is the closest airport to the project site, located approximately 2 miles northeast of the site. While occasional airc�aft overflights are audible, intermittent aircraft noise is not a significant contri6utor to the ambient noise environment. The Burlingame Downtown Specific Plan IS/MND identifies that the project site is within the airport land use plan (ALUP) for SFO; however, the project site does not fall within the fi0 dB CNEL or higher contours of noise generated by planes taking off and landing. As a result, both exterior and interior noise {evels resulting from aircraft would be compatible with the project; therefore the project would result in a less-than-significant impact. f) For a project within the vicinity of a private airstrip, would the project expose people residing or working in the project area to excessive noise levels?

While the projed would provide employment opportunities, it would be uniikely that the development would be large enough to attract growth on a regional level from the amount of jobs it would provide. The project would conform to the Burlingame Downtown Specific Plan, Zoning Code regulations. The project would be an infill-type development. As a result, the project would not indirectly induce growth through intensification and development of surrounding land uses because the surrounding areas are already developed. Additionally, the project would not involve the extension of an existing road or infrastructure that would provide access to other portions of the City and county.

The memo describes the existi�g and future conditions for transportation with and without the proposed commercial develapment. Additionally, information on the regional and local roadway networks, pedestrian and transit conditions, and an anatysis of the effects on transportation facilities associated with the project are included. Additionally, a peer review of the Trip Generation and Parking Analysis was prepared by Abrams Associates in Odober 2015 to corroborate the deductions made by Nelson/Nygaard. The prnject site is located just west of US 101 and east of EI Camino Real; both are major t�affic corridors providing access to Burlingame. Transit facilities serving the projectsite include public transit and pedestrian and bicycle facilities. Two major public mass transit operators, Samtrans and Caltrain, provide service adjacent to the project area. The project site is approximately 0.2 miles from the Calt�ain station, and 0.125 miles from the Samtrans bus station (route 292). Additionally, all of the roads within a 0.25 mile radius of the project site contain sidewalks for pedestrians and 25 percent of the roads include complete bike lanes for bicyclists. 60 Inidal Study Dtscussion 988 Howard Avenue a) Cause an increase in tra�c which is substantial in relation to the existing traffic load and capacity of the street system (i.e., result in a su6stantial increase i� either the number of vehicie trips, the volume-to-capacity ratio on roads, or congestion at intersections)? (less Than Significantj The project site is fully developed with commercial land uses and the lot is paved and generates approximately 674 daily trips. As autlined in the project description, the project proposes the construction of a new three- story building with a basement that would include a mix of retail and office land uses. New occupants of the building would be within walking distance of the downtown area with easy access to retail and restaurants. Additionally, the project site is (ocated 0.2 miles from the Burlingame Caltrain Station and 0.125 miles from Samtrans public transit. Based on the Trip Generation Analysis, implementation of the project would result in a total trip reduction of up to 16Z percent. The standard ITE trip generation rate would be 306 daily trips for proposed office/retail developments of the size and scope of the project; however, the project would generate fewer trips due to the close proximity of public transit and downtown amenities. The Trip generation analysis prepared for the project shows that the number of trips generated by the project would be 256 daily trips, including 27 new AM peak trips and 23 new PM peak trips. As shown in Table 6, the net trips, with pass-by trips included, the project would have a similar amount of daily trips when compared to existing conditions9. Given the project's close proximity to public transit facilities, and the availability of commercial resources to the project site, there is no expected increase in traffic in relation to the existing conditions. Impacts are anticipated to be less than significant.

(No Impact) The City/County Association of Governments of 5an Mateo County 2013 Congestion Management Program (C/CAG 2013, CMPj requires new development projects that generate 100 or more net new peak hour trips to the CMP raadway to implement Travel Demand Management (TDM) measures that would reduce potentia) impacts. The CMP excludes construction traffic from conformance with CMP traffic Level of Service (LOS) standards. 9 A pass-by trlp is made by tra�c already using the adjacent roadway and enter the site as an intermediate stop on the way from another destination. The trip may not necessarily be "generated" by the land use under study, and thus, not a new trip added to the transportation system. 61 IniUal Study 988 Howard Avenue As described in question a), the project site is fully developed with commercial land uses and the lot is paved and generates approximately 674 trips per day. The project would include the construction of a new three- story building with a basement that would include a mix of retail and commercial land uses. Daily vehicle ingress/egress would generate 256 daily trips and thus would be lower than curzent vehicle ingress/egress given the ciose proximity of the proposed project to downtown amenities, and public transit. When taking into account the pass-by traffic from adjacent roadways, the projec� would generate approximately 29 AM peak trips and 32 PM peak trips, which is the same amount of peak hour traffic as the existing gas station. While construdio� activities would require additional trips for hauling material and equipment to and from the project site, such efforts would be temporary in nature and (imited to associated construction activities. The new facility is not expected to generate 100 or more peak hourtrips to the US 101 or SR 82 (CMP roadevays) given that the new facility would generate fewer trips than existing conditions. As such, the project would not significantly conflict with the applicable congestion managernent program, and there would be no impact with project implementation. c) Result in a change in air traffic patterns, including either an increase in traffic levels or a change in location that results in substantial safety risks? (No Impact) SFO is approximately 2 miles north of the project site. According to the Burlingame powntown Specific Plan IS/MND, the project site is within the 19965an Mateo Comprehensive Airport Land Use Plan (ALIJP)10. The proposed development entails the construction of a three-story building, and no aircraft use would be required for operation or construction of any of the project buildout. As such, the project would not lead to an increase in air traffic, and no impact would occur. Therefore, the project would result in n� impact. d) Substantially increase hazards due to a design'feature (e.g., sharp curves or dangerous intersections) or incompatlble uses (e.g., farm equipment)? (Less Than Significant) The project would have two unsignalized entry/exit points; one on East (ane, the other on Howard Avenue. Based on the traffic memorandum prepared for the project, there are no anticipated increases in safety or operational hazards associated with project implementation. Motorists exiting the site would have sufficient site distance at the two proposed driveways. The project site design has been required to confo�m to design standards and is not expected to create impacts to pedestrians, bicyclists, or traffic operations, Therefore, impacts associated with potential increases in hazards due to project design features would be less than significant. e) Result in inadequate emergency access? (less Than Significant) The project would not change the existing roadway systems, and would be easily acce5sible to emergency --_. __ _. vehicles. All lane widths within the project would meet the minlmum width that can accommodate emergency vehides and the final emergency vehicle access plan would be subject to final approval from the Fire Department. Additionally, emergency vehicles have the right of way during an emergency when their sirens are turned on, and other vehicles are required to pull over to the side of the road.

As stated above, the project site is approximate(y 0.2 miles from the Caltrain station, and 0.125 miles from the Samtrans bus station, and would promote continued use of these pubiic transit facilities. The amount of daily trips generated by the project would be less than existing conditions, but similarto existing conditions when accounting for pass-by traffic. Therefore, the project would not result in degradation of the levei of service on any roadway segments currently being.utilized by bus transit in the area and, as such, no significant impacts to transit are expected.

According to the City of Burlingame 2010 Urban Wafer Management Plon, the City's average water demand is 4,32 million gallons per day (mgd), or 82 percent of the City's 5.23 mgd allotted supply. 64 Iniqal Study 988 Howard Avenue Generally, 43 percent of water consumption is from single-family residential uses,l8 percent by multi-family residential uses,l4 percent by industrial uses,l0 percent from commercial uses, 6 percent from ir�igation uses, and 2 percent from institutional uses?1 The City's Public Works Department services the Burlingame's wastewater system. Wastewater flows are carried to the Waste Water Treatment Plant (WWTP) at 1103 Airport Boulevard, which serves the entire City of Burlingame as well as approximately one-third of the Town of Hillsborough. According to the Burlingame Downtown 5pecific Plan IS/MND, average daily flow through the WWTP is 3.2 mgd, or 58 percent of the facility's 5.5 mgd capacity. Burlingame's stormwater system conveys runoff from upstream resldential tributary areas through the Downtown area and east towards the San Francisco Bay. The Street and Sewer Division of the Burlingame Department of Public Works maintains the stormwater inrtrastructure within the City. The aging downtown system is exceeding design capacity, which makes the downtown area prone to flooding during large storm events. x2 The existing site is completely paved, and drains to a catch basin in the northern portion of the site and curbside gutters that empty to a 15 inch stormwater drain line atong Myrtle Road. Allied Waste Industries (AWI) provides solid waste collection, transportation, and disposal services to the City of Burlingame. AWI hauls waste to the San Carlos TransferStation, located at 25 Shoreway Road in San Carlos, then to Ox Mountain Sanitary Landfill, located at 12310 San Mateo Rd, Half Moon Bay. This facility has a maximum throughput of 3,598 tons per day and had a remaining capacity of 26,898,089 cubic yards (as of January May 31, 2011)13.

(No Impact) The project site is fully developed with commercial land uses and the lot is paved. Wastewater generated on the project site would continue to originate from commercial sources and no industrial wastewater would be generated by the project. As a result, no specific changes to the wastewater treatment plan wauld be required to treat these flows.

(Less Than Significant) The project site is fully developed with commercial land uses and the lot is paved. As autlined in the project description, the projectwould construct a newthree-story building with a basement that would include a mix of retai) and commercial land uses. The building footprint would cover approximately 73 percent of the lot (11,160 sf of the 15,352 sf lot). The existing project site is connected to the City's utility infrastructure and includ�s 10-inch water lines and 6-inch sanitary sewer lines. The new building would tie-in to these existing lines. With regards to water and wastewater, the project would increase water demand and wastewater generation because the square footage of the building would increase from the existing site. The Department of Public Works has indicated that the 6-inch sanitary sewer line that serves the subject property is at or near capacity. While the proposed project would not result in a significant increase jn wastewater generation, it may require that the (ine be upsized. The applicant will need to do an analysis to determi�e if the sewe� main requires upsizing. This analysis will be reviewed by the City and if required, the applicant will be required to pay for their pro-rata share of the upsizing or a designated �un of the line, the details ofwhich would be determined by the �epartment of Public Works priorto building permit approval. The existing 10-inch water line is sufficient to provide for the increased need in water usage for the proposed uses; however new construction is required to comply with California Fire Code requirements for fire flow, based on the size of the building and type of construction, and hydrant spacing. Upon building permit submittal Central County Fire Department will require that the project comply with State fire code for emergency water supply (hydrants) with regard to the increase of square footage at the project site and necessary flow rate (gallons per minutesJ. However, as noted in the setting discussion above, the City's water and wastewater infrastructure serving the project site would continue to have capacity to handle the project and would not require construction of additional facilities.

According to AWI, which owns and operates the Ox Mountain Landfill, the landfill has a remaining life period that extends beyond #he existing 15-year agreement at current disposal rates. The existing project site is developed with commercia! land uses. The proposed project would likely increase the overall solid waste generation because the building would increase in size. However, such an increase would be negligible and the Ox Mountain landfill would continue to have plenry of capacity foc such a negligible increase.

(Less than signi�cant) The project site does not provide suitable habitat for any regionally occurring special-status plant or wildlife species for the following reasons: (1} the site is in a densely developed urban area and is isolated from areas of natural habitat; and (2) the site is paved and is being actively used as a gas station and auto repair maintenance shop. Therefore, impacts to special-status plant and wildlife species from development and operation of the project are not expected to occur. Mitigation measures are provided for pre-construction surveys for nesting/breeding birds to further protect such bird communities. Mitigation measures that would adequately protect a known historical resource and any currently unknown cultural resources that may be uncovered during project construdion are also included herein. With this mitigation, the project would not have the poten#ial to degrade the quality of the environment; affect habitat, fish, and wildlife species; or cultural resources:------ C�' IniGal Study 988 Howard Avenue b) Does the project have impacts that are individually limited, but cumulative considerable? ("Cumulative considerable" means that the incremental effects of a project are considerable when viewed in connestion with the effects of past projects, the effects of other current projects, and the effects of probable future projects)? (Less than Significant) The existing project site is currently developed for commercial uses. The project inciudes demolishing the existing structure and constructing a three-story building with a basement and the proposed uses would be a mix of retail and commercial uses. The project would have potential impacts to aesthetics, air quality, biology, cultural resources, geology and soils, hazards and hazardous materials, and noise. Incorporation of mitigation measures would reduce these impacts to a less-than-significant level. The project site is already developed for commercial uses. Although the proposed project would construct a commercial building that would increase the squarefootage from existing conditions, such an increase would not be substantial enough to make a cumulatively considera6le contribution. Furthermore, the project site is governed by the City's Generai Plan, Burlingame Downtown Spetific Plan, and the Burlingame Municipal Code (BMC). According to the Burlingame Downtown Specific Plan IS/MND, the project site and adjacent parceis are designated MMU, which supports retail and office uses. The project would tedevelop a vacant commercial property and construct a building with a mix of retail and commercial uses, which is consistent with Chapter 25,34 MMU District Regulations ofthe BMC. c) Does the project have environmental effects which will cause substantial adverse effects on human beings, either diredly or indirectfy? (Less than Significantj The implementation of the mitigation measures identified herein wou Id redute all potential impacts to a less- than-significant levei. Therefore, the project would thus not result in impacts that would cause substantial adverse effects on human beings, either directly or indirectly. 70 IniGal 51udy References 988 Howard Avenue Abrams Associates.
