General Plan Designation: Mixed Use — Office/Residential (North Burlingame/Rollins Road Specific Plan) 7. Zoning: TW (Trousdale West) (Chapter 25.40), Off -Street Parking Regulations (Chapter 25.70) 8. Description of the Project: The proposed project consists of a new four-story 79-unit assisted living facility at 1818 Trousdale Drive. The project would include demolition of the existing one-story office building and existing parking lot and provide for the new building with one level of below -grade parking (see Figure 2). The proposed assisted living facility would contain a total of 79 units. The main pedestrian entrance to the facility is proposed at the corner of Ogden Drive and Trousdale Drive, with a pick-up and drop-off area on Ogden Drive. The first and second floors would contain assisted living units and related common activity and support services. The third floor would contain suites for memory -impaired residents. The fourth floor is also intended for memory -impaired residents and would be similar to the third floor but with lower staffing requirements and increased amenities for residents. Common areas on the first floor include the dining room, bistro, and parlor. Other amenities such as media rooms, activity rooms, hair salons, etc., are located on the different floors throughout the facility. The assisted living units are a mix of one -bedroom, two -bedroom and "Denver" units that can accommodate one or two persons. Typical units range in size from 450 square feet to 680 square feet (Mithun Architects 2005a). The proposed exterior of the building would include stucco walls, vinyl clad double -hung wood windows, stained wood windows and doors at first floor public places, and a concrete tile "terra cotta" roof. On the first floor, low retaining walls with a wrought iron decorative railing and a metal and glass trellis canopy over the corner entrance and connecting walkways are Sunrise Assisted Living Facility Draft IS/MND MHA Inc. 5 June 2006 CITY OF BURLINGAME proposed. The proposed building, as measured to the roof ridge, is 56 feet, 7 inches above average top of curb on Trousdale Drive. The project would include a total of 36 parking spaces in the below -grade parking garage (24 standard, 10 compact, and 2 disabled -accessible spaces). The ingress/egress ramp to the below -grade parking garage is located on Ogden Drive along the left side property line. On - site parking for a delivery van and facility shuttle is provided at the rear of the building accessible from Trousdale Drive. Drop off/pick up of persons would be conducted in the below -grade parking garage as well as at street level on Ogden Drive. The applicant projects a maximum of 23 full-time and 13 part-time employees on weekdays and 13 full-time and 11 part-time employees on weekends. The applicant anticipates a maximum of 15 visitors per day (Sunrise Development 2005). The project landscape plan includes installation of trees, shrubs, groundcover, vines, site furniture, patios and decorative paving to be installed throughout the site. The project also includes installation of street trees along Trousdale Drive (Golden Rain trees) and Ogden Drive (Chinese Tallow trees) as required by the North Burlingame/Rollins Road Specific Plan. All 13 existing trees would be removed and approximately 50 new trees would be planted. Discretionary review for the project will include: • Conditional Use Permits for exceptions from the North Burlingame -Rollins Road Specific Plan and TW District zoning requirements for height above 35 feet along Trousdale Drive and along Ogden Drive. • Variances from the TW District zoning requirements to allow a proposed trellis canopy to encroach into the 10 foot front setback on Trousdale Drive and Ogden Drive. • Design review by the Planning Commission. 9. Surrounding Land Uses and Setting: The site is located at the northwest corner of Trousdale Drive and Ogden Drive. There is currently a one-story, vacant office building (approximately 15,000 square feet) and associated surface parking (64 spaces) on the site. The property is bordered to the west and south by multi -family residential buildings and to the east and north by offices and medical uses. The temporary main entrance for the Peninsula Medical Center is located across the street at the southeast end of the hospital site. This entrance will be used as the main entrance to the hospital for patients, visitors, and emergency vehicles for the next (approximately) six years, while the new hospital is under construction. After the new hospital is occupied, this entrance will become the hospital's emergency and main staff entrance. The project site is flat at the center with a grade change (cut) of 3-5 feet on the uphill sides adjacent to Trousdale and Ogden Drives. Other than the existing building and surface parking, there are 13 trees on the property, most of which are within 10 feet of Trousdale and Ogden Drives, though located on the applicant's property. 10. Other public agencies whose approval is required: None. 6 MHA Inc.

J ENVIRONMENTAL ANALYSIS 1. Land Use and Planning The project site is currently occupied by a single -story, vacant office building (approximately 15,000 square feet) and associated surface parking, and was most recently used by State Farm Insurance as a claims office. The property is bordered to the west by multi -family residential buildings and to the east, south and north by offices and medical uses. The temporary main entrance to the Peninsula Medical Center is located across the street at the southeast end of that site. This entrance will become the emergency and staff entrance to the hospital when the construction of the new hospital is complete in 2010. Replacement of the office building by an assisted living facility for seniors would not physically divide the community because it would be bounded by compatible residential and medical uses on all sides. Compliance with the policies and regulations of the North Burlingame -Rollins Road Specific Plan and with the TW (Trousdale West) District zoning is discussed below. North Burlingame -Rollins Road Specific Plan The project site lies within the Trousdale West area of Burlingame and land use is governed by the North Burlingame -Rollins Road Specific Plan (Burlingame 2004). The site is further located within the North of Trousdale Drive subarea and the El Camino Real Design District of the Specific Plan. The designated land use for the subarea is "Mixed -Use — Office/Residential," which includes multi- family residences, offices, health services, financial institutions and residential care facilities for the elderly. The proposed land use is therefore consistent with the Specific Plan land use designation. Policies included in the North Burlingame -Rollins Road Specific Plan emphasize access to area transportation hubs, the economic benefits of the two subareas, mixed use development and health service opportunities, street design, and visually attractive development. Policies related to design are addressed in the Aesthetics and Visual Resources section. The proposed project complies with all other policies of the Specific Plan. The Specific Plan, however, requires a Conditional Use Permit for height above 35 feet along both roads, not to exceed 60 feet on Ogden Drive and 75 feet on Trousdale Drive. The proposed maximum height (52'6" along Ogden Drive and 567' along Trousdale Drive) is less than the maximums prescribed in the Specific Plan (Hurin 2005a). Exceptions to these criteria may be granted by approval of a Conditional Use Permit. The identified conflicts with the Specific Plan criteria are potentially significant impacts. Those impacts are addressed in the mitigation of visual impacts in the Aesthetic and Visual Resources Sunrise Assisted Living Facility Draft IS/MND MHA Inc. 17 June 2006 CITY OF BURLINGAME section (see Mitigation Measures 2.1, 2.2, and 2.3). With the implementation of proposed landscape improvements and these mitigation measures, the impacts of the exceptions would be reduced to a less than significant level. The policy considerations of the Specific Plan criteria to encourage a more urban, pedestrian -oriented design are most appropriately addressed through the Conditional Use Permit and Design Review processes. Zoning Ordinance The project is subject to the land use limitations and standards of the TW (Trousdale West) district in the Zoning Ordinance (Burlingame 2005d). These zoning requirements were adopted for the Trousdale West District on September 19, 2005 to provide consistency with the North Burlingame - Rollins Road Specific Plan. The TW provisions allow a group residential facility as a "permitted use." The TW District regulations and the Specific Plan do not limit the density of the facility, so there is no conflict with density provisions of the Zoning Ordinance. The building setbacks generally comply with the setback requirements of the TW District, except that the setbacks for the trellis canopy in the front (Ogden) and side (Trousdale) yards are less than 10 feet, where a minimum of 10 feet is required. A variance from those front setback limitations would therefore be required. The Minimum Building Frontage requirements of the TW District zoning specify that a minimum of 60% of the building must be located at the 10-foot setback line along both Ogden and Trousdale Drives. The project complies with the requirement along both roads. The project would also require a Conditional Use Permit to allow the building height on both Ogden and Trousdale Drives to exceed 35-foot review line for the TW zone. A maximum height of 56 feet 7 inches is proposed along Trousdale Drive and a maximum height of 52 feet 6 inches is proposed along Ogden Drive. These heights are consistent, however, with the maximum heights allowed with a Conditional Use Permit (75 feet on Trousdale and 60 feet on Ogden). The identified conflicts with the TW District zoning standards are potentially significant impacts. Those impacts are addressed in the mitigation of visual impacts in the Aesthetic and Visual Resources section (see Mitigation Measures 2.1, 2.2, and 2.3). With the implementation of proposed landscape improvements and these mitigation measures, the impacts of the variances and conditional use permit exceptions would be reduced to a less than significant level. There are no Habitat Conservation Plans or similar natural resource plans applicable to the project area. Therefore, no impacts on such plans would occur from implementation of the proposed project. 2. Aesthetics and Visual Resources The information in this section is summarized from a visual impact analysis prepared by 2M Associates (2M Associates 2005). The project area consists of a minimally -distinctive urban environment with a moderate to low degree of scenic integrity. Vegetation consists of sparse street trees and mixed ornamental landscape around individual developments. The streetscapes of Trousdale Drive and Ogden Drive are dominant. From a public perspective, the existing project site is distinctive only for its landscaping. This includes five mature olive trees located along Ogden Drive. The land use immediately surrounding the project site consists of two to four-story multi- family residential buildings to the west, and one to three-story office buildings and retail stores to the north, east, and south. Visibility The project site is not in the direct terminus from any surrounding street's line of sight. Because of the low -profile development now existing on the property, the project site is not readily noticeable 18 MHA Inc. Sunrise Assisted Living Facility Draft IS/MND June 2006 CITY OF BURLINGAME from El Camino Real. Direct views to the site are limited to an approximately one block area along Trousdale Drive, Ogden Drive, and from the intersection of Marco Polo Way and Trousdale Drive (see Figure 3). North Burlingame/Rollins Road Specific Plan The project site is located within the North of Trousdale Subarea and the El Camino Real Design District of the North Burlingame/Rollins Road Specific Plan (City of Burlingame 2004). The Specific Plan Design Guidelines emphasize enhancing the urban aesthetics of the area and establishing a pedestrian -oriented streetscape. Under the land use designation of "mixed -use - office/residential," building height and bulk considerations within the El Camino Real design district of the specific plan are addressed through the following standards (these standards are intended in the Specific Plan to be mandatory and are reflected also in the TW (Trousdale West) District zoning regulations): • Build -to Lines. The Build -to Line prescribes a very specific setback that defines the space between the sidewalk and the front fagade of a building. The Build -to Line for both Trousdale and Ogden Drives is 10 feet. • Minimum Percent Frontage. New buildings on both Trousdale and Ogden Drives shall have a minimum 60% of their frontages built to the Build -to Line. • Maximum Building Heights. The maximum building heights for the project site are: - Trousdale Drive: 75 feet maximum. - Ogden Drive: 60 feet maximum Corner parcels fronting onto streets where two standards meet may have the higher maximum building height wrap around the corner onto the street where the lower maximum building height is otherwise required for a distance of 30 feet. • Street Trees. The Specific Plan also presents recommendations for street trees and alternates. These include: Trousdale Drive Golden Rain Tree Red Oak (Koelreuteria paniculata) (Quercus rubra) Ogden Drive Red Flowering Gum Chinese Tallow Tree (Eucalyptus ficifolia) (Sapium sebiferum) Visual Impact Analysis In addition to field observations conducted in October and November 2005, the visual impact analysis is based on review of the following information: ground -level photographs of the project site from representative viewing locations along Trousdale and Ogden Drives; project plans and drawings provided by the applicant (Mithun 2005a); and relevant City of Burlingame plans and policies as contained the Burlingame General Plan and North Burlingame/Rollins Road Specific Plan. The assessment employed a line -of -sight analysis to consider the net visual presence that could result from development as seen from key publicly -accessible observation points. These points are illustrated in Figure 3.

Direct Views to Project Site Photo Locations La M .I 0 200' 400' 1 FEET A series of post -project photo -montages were prepared to present a reasonably accurate depiction of overall project visibility and the general impact of the proposed building mass and scale on the site. Elevation drawings provided by the applicant were used as the basis of the building design in the photo -montages. The photo -montages do not include building color and fenestration or related site improvements including, but not limited to, landscaping, lighting, signs, or plaza areas. The photo -montages were based on the applicant's original set of plans, dated May 23, 2005. The revised plans orient the building to Ogden Drive rather than Trousdale, and move the building frontage closer to the street to better comply with the North Burlingame/Rollins Road Specific Plan. The photo -montages have not, however, been modified, as the materials, height and massing of the buildings would be very similar to the original and result in no new significant building mass impact. Impacts on Scenic Vistas There are no designated state or county scenic vistas within the El Camino Design District or the immediate project area. The project site is not visible from any state or county scenic highway within Burlingame. No mitigation is required relative to views from a scenic vista. El Camino Real 20 MHA Inc. Sunrise Assisted Living Facility Draft IS/MND June 2006 CITY OF BURLINGAME and Trousdale Drive, however, are designated as Scenic Connectors in the City's General Plan, and are discussed below under Visual Character of the Site and Surroundings. Because of the height of the proposed structure, easterly views from approximately 10 private housing units that front Ogden Drive would be foreshortened. These views now look over the open parking area of the existing site. They would be replaced with views that, to varying degrees, would be directed to focus on the project's perimeter landscaping and the vehicular ramp leading down to the parking garage and the northeast corner garden area. With the implementation of the following mitigation measure, the potential impacts will be reduced to a less than significant level. Mitigation Measure 2-1: To screen views to the parking garage ramp from the residences to the west, plans shall include a trellis structure planted with vines to span over the ramp or additional space for planting trees whose canopy will be sufficient to cover the driveway. Landscaping and Trees The proposed project would remove virtually all site vegetation (Gates 2005), including trees along Ogden Drive and Trousdale Drive. New street trees proposed (Chinese Tallow trees on Ogden and Golden Rain trees on Trousdale) are consistent with the street trees required by the Specific Plan. The proposed landscaping would establish a sense of unity and would enhance the vividness of the Ogden Drive and Trousdale Drive landscapes while also enhancing northern views from Trousdale Drive passing by Ogden Drive. No significant impacts are expected and no further mitigation is required. Visual Character of the Site and Surroundings Figure 3 illustrates the general area from which the proposed project would be distinctly noticeable. The project would be most visible to the general public from Trousdale Drive. The length of time the project would be seen is dependent on the time spent at nearby traffic lights, but would generally be shorter than one minute. The landscape plan (Gates 2005), including proposed street trees, accent plantings, trellises, a monument sign, and garden walls would generally enhance the character of the existing landscape and advance the goals, objectives, policies and implementation actions of the City of Burlingame General Plan and North Burlingame/Rollins Road Specific Plan. The proposed building structure, at a maximum height of 56 feet 7 inches along Trousdale Drive and 52 feet 6 inches along Ogden Drive, conforms with the maximum height limits for Trousdale (75 feet) and Ogden (60 feet) Drives as identified in the North Burlingame/Rollins Road Specific Plan and the TW District regulations, but requires a Conditional Use Permit to exceed the 35 foot review line. While this height is considerably taller than existing buildings in the immediate area, the Specific Plan anticipates and directs such an increase in height and intensity within its boundaries. The building setbacks generally comply with the Build -to Line of 10 feet as identified in the Specific Plan (except for the trellis canopy, which encroaches closer than 10 feet). The proposed setbacks would be a maximum of 10 feet for at least 77.5% of the Ogden Drive frontage and 60% of the Trousdale Drive frontage, in compliance with the zoning specifications. The intent of the Build -to Line and Minimum Percent Frontage requirements is to establish a streetscape design that is more urban in character and encourages greater pedestrian activity. This evaluation of the urban design components of the project is not addressed through environmental review of the project, but is considered through the Planning Commission's design review. The proposed design allows for adequate landscaping, is visually consistent with the multi -family residential development on the west side of Ogden, and is generally consistent with the urban design parameters of the Specific Plan. Sunrise Assisted Living Facility Draft IS/MND MHA Inc. 21 June 2006 CITY OF BURLINGAME Figures 4 through 11 illustrate existing views and a reasonably accurate depiction of overall project visibility and the general impact of the proposed building mass and scale as seen from four viewing locations around the project site (see Figure 3). These images are not intended to represent the details of the proposed design and associated landscaping. The photo -montages are, as noted previously, based on the applicant's original plans submitted in May of 2005. Revised images have not been developed as staff and the environmental consultant determined that no new significant massing or view impacts would result from the new design, given its similarity in materials, height, and building mass. Trousdale Drive west of Sequoia Drive is designated as a local scenic route. The connector portions of Trousdale Drive and El Camino Real provide connections between the tree -lined portion of El Camino Real to the south and the wide open vistas on Trousdale Drive west of Sequoia Drive. El Camino Real and Trousdale Drive between Sequoia Drive and California Drive are designated as Scenic Connectors in the City's General Plan, and the Plan's Scenic Roadway Action/Implementation Guidelines outline several policies related to protecting and enhancing scenic roads. While most of these policies pertain to scenic highways and roads (not scenic connectors), policies SR(2) and SR(8) suggest landscape treatment and design review should be required to enhance all scenic routes. Landscaping for the project will be improved significantly over existing conditions and the Planning Commission will review the project's design to assure that building articulation, colors, and other design elements are visually attractive from Trousdale and Ogden Drives. These measures will also minimize the view impacts from El Camino Real, although the project will not be highly prominent from that road. No further mitigation is required. Light and Glare As seen from the surrounding streets, there is a potential for sun reflection from the proposed structure to create glare because of the open character of the project development site. Mitigation Measure 2-2 will help reduce potential glare as seen from the nearby street system and adjacent residences. Mitigation Measure 2-2: Flat, non -reflective paint or integrated coloring shall be used in all exterior building materials throughout the project. Direct or vagrant nighttime lighting would be seen in foreground views from the nearby streets and adjacent residences, which could cause a significant visual impact. Implementation of the following mitigation measure cannot eliminate the new light sources, but would reduce project nighttime glare to a less -than -significant level. Mitigation Measure 2-3: Prior to issuance of a building permit, a detailed Exterior Lighting Plan shall be provided to the City of Burlingame for review. The lighting plan shall be based on the following standards: a. The cone of light from all light fixtures shall be focused on the site and stray light shall be controlled through use of low -brightness fixtures with optical controls. b. All exterior light sources shall be shielded and fully blocked from off -site views, except for the street address. c. No uplighting of the structure or vegetation shall be permitted from any outdoor light fixture. d. On -demand exterior lighting systems shall be employed where feasible. Area lighting and security lighting will be controlled by the use of timed switches and/or motion detectors. The implementation of the above measures would reduce the potential light and glare impacts to a less than significant level. 22 MHA Inc.

Sunrise Assisted Living Facility Draft IS/MND June 2006 CITY OF BURLINGAME 3. Traffic and Transportation The information in this section was prepared by Fehr & Peers Transportation Consultants. The project site is located just west of El Camino Real, between US Highway 101 (US 101) and Interstate 280 (1-280) near the Peninsula Medical Center. Specifically, the project sits at the corner of Trousdale and Ogden Drives. The Millbrae BART/Caltrain station is located about one-half mile to the northeast. Traffic Impacts Traffic operations at intersections are typically described in terms of "Level of Service" (LOS). LOS is a qualitative measure of the effect of several factors on traffic operating conditions, including speed, travel time, traffic interruptions, freedom to maneuver, safety, driving comfort, and convenience. It is generally measured quantitatively in terms of vehicular delay and described using a scale that ranges from LOS A to F, with LOS A representing essentially free -flow conditions and LOS F indicating over -capacity conditions with substantial congestion and delay. Analysis of study intersections is typically conducted using methods described by the Transportation Research Board (TRB) in the 2000 Highway Capacity Manual (HCM). For intersections, LOS is based on "control delay." Control delay is defined as the delay directly associated with the traffic control device (i.e., a stop sign or a traffic signal) and specifically includes initial deceleration delay, queue move -up time, stopped delay, and final acceleration delay. These delay estimates are considered meaningful indicators of driver discomfort and frustration, fuel consumption, and lost travel time. Tables 1 and 2 present the relationship between LOS and control delay for signalized and unsignalized intersections, respectively. Background Conditions Traffic Operations An EIR was recently prepared for the proposed reconstruction of the Peninsula Medical Center. That EIR states that with the addition of traffic from currently -approved but not yet constructed projects and the expected traffic from the proposed reconstruction of the Peninsula Medical Center, four nearby intersections are expected to operate at the following LOS in the AM and PM peak hours, as shown in Table 3. Trip Generation Fehr & Peers conducted trip generation studies at three existing similar sized Sunrise Assisted Living facilities in Northern California. These studies were conducted in 2003 as part of a traffic study for another Sunrise Facility in Palo Alto, California. The trip generation studies at other sites were performed by counting the number of cars entering and exiting each of the three sites during typical weekday peak periods (7:00 to 9:00 AM and 4:00 to 6:00 PM). The number of cars entering and exiting each site during the peak hour of the two-hour peak period observed were divided by the number of rooms at each of the sites to determine the average number of inbound and outbound vehicle trips generated per room during typical weekday AM and PM peak hours at each site. The average of the three peak hour trip generation rates was calculated to determine the average peak hour trip generation rate per room for a typical Sunrise Assisted Living Facility. This average trip generation rate, based on observations at three similar facilities in Northern California, was compared to the national average trip generation rate for assisted living facilities, as reported in Trip Generation, 7th Edition, Institute of Transportation Engineers (ITE).The average trip generation rates based on local studies of Sunrise Assisted Living Facilities in Northern California are slightly higher than the ITE rates for land use #253 (Assisted Living Facility) based on dwelling units or occupied rooms. Therefore, the analysis in this report of the proposed Burlingame facility is based on the higher trip generation rates, which are from field measurements of similar uses, and hence present a conservative forecast. Table 4 shows the trip generation rates Sunrise Assisted Living Facility Draft IS/MND MHA Inc. 27 June 2006 CITY OF BURLINGAME Table• -• Intersection L• A < 10.0 Operations with very slight delay, with no approach phase fully utilized.

SOURCE: Fehr & Peers, September 2005 per room derived from studies at three similar sites and the resulting forecasts for the proposed Burlingame facility, based on the number of rooms. The proposed project will have a project staffing population of 32 employees. The peak number of staff at any given time is expected to be 22 employees, between 10 AM and 2 PM. Shift changes during which some staff will be arriving at the same time as other staff is leaving are expected to occur between 6:00 and 7:00 AM and 2:00 and 3:30 PM. This will fall outside of the typical weekday peak period, and is consistent with other Sunrise Assisted Living Facility sites. Therefore, the peak hour trip generation rates shown in Table 4 are reflective of proposed staffing at the Burlingame facility. As reported in the Peninsula Medical Center Replacement Project EIR, the main daytime period during which hospital shift changes occur is between 2:00 and 4:00 PM on typical weekdays. The proposed Sunrise project staff would turn over during approximately the same time, between 2:00 and 3:30 PM. Thus the effects of the two shift changes would be combined. However, the amount of staff turning over during this afternoon time associated with the proposed assisted living facility project would be less than 30, compared to the 389 afternoon trips generated by the Peninsula Medical Center project. As shown in Table 4, the proposed 79-room facility would generate 9 total trips during a typical weekday AM peak hour and 27 total trips during a typical weekday PM peak hour. This is based on the assumption that the proposed Burlingame facility will generate traffic at a rate consistent with the three other Sunrise Assisted Living facilities surveyed in Northern California. Project Impacts The City of Burlingame has jurisdiction over all city streets and city -operated traffic signals. Several regional agencies, including the City/County Association of Governments (C/CAG), coordinate and establish funding priorities for intra-regional transportation improvement programs. C/CAG is the Congestion Management Agency (CMA) that sets the state and federal funding priorities for improvements affecting the San Mateo County Congestion Management Program (CMP) roadway system. C/CAG-designated CMP roadway system components in Burlingame include State Route (SR) 82 (El Camino Real), US 101, and 1-280. There are two CMP-designated intersections in the vicinity of the proposed project, El Camino Real/Millbrae Avenue and El Camino Real/Broadway. The level of service standard for each of these intersections is LOS E. However, no CMP Sunrise Assisted Living Facility Draft IS/MND MHA Inc. 29 June 2006 CITY OF BURLINGAME intersections were evaluated in this analysis due to the combination of relatively low expected project -related traffic generation and the relative distance of CMP intersections from the proposed project site. The City of Burlingame does not have a formally -adopted LOS standard for non-CMP intersections. However, transportation analyses performed in the City have historically assumed that intersections should operate at LOS D or better during the AM and PM peak hours. This standard is consistent with most cities in the Bay Area and is assumed to be the LOS standard for this project for non-CMP intersections. Therefore, if the proposed project were to contribute traffic to a non-CMP intersection in a way that it would cause the AM or PM peak hour LOS to deteriorate from LOS D or better to LOS E or F, the proposed project would be said to have a significant impact to traffic operations. Similarly, if the proposed project were expected to contribute substantial amounts of traffic to a non-CMP intersection operating at LOS E or F without the project, the proposed project would be considered to have a significant impact to traffic operations. C/CAG has also adopted guidelines for the land use component of the CMP. The purpose of the guidelines is to reduce the impacts of the traffic created as a result of new development. The guidelines must be followed for all projects that generate 100 or more net new peak hour trips on the CMP network and are subject to CEQA review. If a project meets the above mentioned criteria, the project sponsor should determine if a combination of acceptable options/measures will fully reduce the net number of trips that this project is anticipated to generate on the CMP roadway network (including the first 100 trips). As shown in Table 4, the proposed project would generate 27 PM peak hour trips, well below 100 peak hour trips, and is therefore exempt from this requirement. As requested by the City of Burlingame, the analysis of traffic impacts associated with the proposed Sunrise Assisted Living facility project was limited to a comparison of expected project trip generation with intersection operations analyzed in the Peninsula Medical Center Replacement Project EIR. As shown in Table 3, above, all four adjacent intersections are expected to operate at acceptable LOS D or better in the AM and PM peak hours with the addition of traffic from other approved but not yet constructed projects and traffic from the reconstruction of the Peninsula Medical Center. The proposed Sunrise Assisted Living project would add 9 trips during the AM peak hour and 27 trips during the PM peak hour. If it is assumed that all project trips, both AM and PM peak, travel through each study intersection, the proposed project would not cause any of the study intersections to deteriorate to an unacceptable LOS E or F. Furthermore, based on engineering judgment, it is not likely that project trips would cause left -turn lanes to overflow and block traffic in the adjacent lanes in the near -term. Therefore, the proposed project would have a less than significant impact to intersection operations in the near term. The amount of traffic that is added to each intersection as a result of the proposed project is provided in Table 5. The current peak hour of traffic varies for each of the four intersections studied. In addition, the forecasted peak hour of traffic generation of the proposed project site varies from the intersection peak hours. However, in order to capture a conservative assessment of traffic impacts, a worst -case is assumed that all of the intersection peak hours occur simultaneously, and correspond identically to the peak hour of traffic generation of the proposed project. As noted earlier, the Peninsula Medical Center staff and the Sunrise Assisted Living facility staff would turn over at approximately the same time, between 2:00 and 4:00 PM. According to the Peninsula Medical Center Replacement Project EIR, without the reconstruction of the Peninsula Medical Center, study intersections would operate at acceptable levels of service during this time. The proposed assisted living project would not generate traffic volumes during this time at high enough levels to deteriorate intersection levels of service to unacceptable levels. 30 MHA Inc.

As requested by City of Burlingame, new intersection LOS calculations were not performed, given the relatively low amount of project -generated traffic and the relatively good operations of study intersections. SOURCE: Fehr & Peers, 2005 Cumulative Impacts Cumulative Conditions are presented to establish the long-term future transportation operating conditions. A Cumulative Conditions analysis was performed to identify potential project impacts under conditions expected to occur in year 2020. The Peninsula Medical Center Replacement Project EIR includes an analysis of expected Year 2020 operating conditions at the four study intersections. To derive Year 2020 traffic volumes, the Peninsula Medical Center Replacement Project EIR analysis assumed that near -term traffic volumes would increase by approximately one percent per year to account for growth in traffic associated with adjacent development. In addition to the one percent annual growth rate, additional traffic associated with full utilization of the newly - opened and currently underutilized Millbrae BART Station and traffic associated with approved and pending projects in the area, including buildout of the Millbrae Station Area Specific Plan, was added. The resulting Peninsula Medical Center Replacement Project EIR cumulative conditions analysis indicated that all four study intersections would operate at acceptable LOS D or better during the AM peak hour in Year 2020. The intersection of El Camino Real/Trousdale Drive would deteriorate to LOS E in the PM peak hour by Year 2020, while the other three study intersections would continue to operate at acceptable LOS D or better. The projected Cumulative Conditions intersection operations are summarized in Table 6. The traffic characteristics of the proposed Sunrise Assisted Living facility project are consistent with the assumptions made with respect to background traffic growth due to development in this area in the Peninsula Medical Center Replacement Project EIR analysis of Cumulative Conditions. Thus, no additional cumulatively significant impacts are expected as a result of the proposed Sunrise Assisted Living facility. However, the proposed project would contribute to a previously - identified cumulatively significant impact at the intersection of El Camino Real/Trousdale Drive. The Peninsula Medical Center Replacement Project EIR identified mitigation at the intersection of El Camino Real/Trousdale Drive that would reduce the cumulative impact at this intersection to less than significant levels (LOS D, to be precise). Because the expected traffic volumes associated with the Sunrise Assisted Living facility are assumed to be included in the traffic forecasts in the Peninsula Medical Center Replacement Project EIR analysis, no additional Sunrise Assisted Living Facility Draft IS/MND MHA Inc. 31 June 2006 CITY OF BURLINGAME Table 6: Peak Hour Worst -Case Intersection Traffic Impact (Cumulative Conditions) Ogden Drive & Trousdale Drive AM 1,754/13 1,763/B 3% PM 1,640/A 1,667/A 9% Marco Polo Way & Trousdale Drive AM 1,705/C 1,714/C 4% PM 1,582/B 1,609/B 10% Magnolia Drive & Trousdale Drive AM 2,167/B 2,176/B 2% PM 2,264/B 2,291 /B 7% El Camino Real & Trousdale Drive AM 3,963/D 3,972/D 1% PM 4,580/E 4,607/E 3% Note:Cumulative volumes without the proposed project were derived by subtracting project total traffic volumes from the total Cumulative plus Project Conditions traffic volumes, based on the worst -case assumption that all traffic uses each study intersection. As requested by the City of Burlingame, no additional LOS calculations were performed for the Cumulative No Project scenario. 2 Cumulative plus Project Conditions traffic volumes and LOS obtained from Peninsula Medical Center Replacement Project EIR, Cumulative + Project Conditions. Since the proposed project is consistent with assumptions for development in this area made in the Peninsula Medical Center Replacement Project EIR to develop cumulative forecasts, the cumulative plus project traffic volumes from that report can be assumed to include the proposed project and are the same as the forecasts for the cumulative analysis for the proposed project. 3 Percentage shown does not include approved projects, such as the Peninsula Medical Center Replacement Project. This represents a worst -case assumption for purposes of calculating project contribution. SOURCE: Fehr & Peers, 2005 mitigation is necessary based on this analysis, and the intersection is still expected to operate at LOS D under Cumulative plus Project Conditions. The Sunrise Assisted Living facility contribution towards the cumulative traffic growth above baseline conditions at this intersection is three percent of the total increase in traffic volume. There is a potential that the project's proximity to the Millbrae Intermodal Transit Station could reduce employee vehicle trips. According to one source, 10 percent of all work trips within a one- half mile of a transit center may be eliminated (Victoria Transport Policy Institute, TDM Encyclopedia. 2003). However, the number of employees making trips to and from the site during peak hours is expected to be quite low given that the employee shifts are generally expected to occur during off-peak hours. Therefore, to be conservative, this analysis does not include a reduction in vehicle trips due to the site's proximity to transit. Passenger Loading and Unloading The majority of the unloading and loading of residents from vehicles would occur inside the parking garage in the vicinity of the main elevator, or in a proposed 60-foot passenger loading zone, designated by a white curb, or in a proposed 84-foot passenger loading zone on Ogden Drive. A designated loading/unloading area has been identified in the garage for off-street passenger loading. The loading/unloading area will be located west of the garage entrance (near Elevator A), where entering and exiting vehicles would be able to maneuver around stopped cars. 32 MHA Inc. Sunrise Assisted Living Facility Draft IS/MND June 2006 CITY OF BURLINGAME Some paratransit vehicles may have difficulty maneuvering in the garages. Implementation of the following mitigation measure would reduce the likelihood that larger vehicles would travel through the garage and would reduce potential circulation impacts to a less than significant level. Mitigation Measure 3-1: The garage shall be restricted to allow passenger vehicles only. Delivery trucks and paratransit vehicles shall use either the service/delivery parking area with access from Trousdale Drive or the 84-foot passenger loading zone on Ogden Drive just south of the proposed garage driveway, for loading and unloading purposes only. Analysis of the June 15, 2006 project site plan found passenger loading and unloading to work adequately. However, the following two issues were identified: • Although feasible, parking maneuvers into and out of stalls 9 and 10 may be difficult for larger passenger vehicles, particularly if a vehicle is stopped in the garage loading zone. • Because on -street parking in the area is sometimes scarce, parking enforcement of the on -street loading area may be required at times. Deliveries Larger vehicles making food deliveries and collecting trash are expected to use the east side of the project site with access to the off-street parking area from Trousdale Drive. There are two designated parking spaces for delivery vans and Sunrise service vehicles. The project's service driveway would be located across the street from the main entrance to the Peninsula Medical Center; however, it would be offset by approximately ten feet and would not precisely line up. Vehicles turning left out of the Hospital driveway would conflict with service vehicles turning left into the project driveway off of eastbound Trousdale Drive. Because of this, the project driveway serving the service parking area will permit right turns in and out only. In addition, the volume of vehicles using the proposed project service driveway would be very low (likely less than ten trips per day) and primarily limited to service vehicles. Because of these factors, the offset of the driveways is considered a less than significant impact. Mitigation Measure 3-2: The driveway serving the small off-street parking area on the eastern side of the proposed project shall be restricted to allow right turns in and out only, to the satisfaction of the City's Traffic Engineer. On -Site Circulation and Garage Access The proposed project would provide a single -level subterranean parking facility. Parking stalls would be located along the facility perimeter and in the center, with a one-way, counterclockwise, circulation aisle in the middle. Access to the parking area would be provided via a driveway from Ogden Drive. This driveway would have restricted sight distance at Ogden Drive due to the following elements: • An existing concrete wall on the north side of the driveway would limit the driver of an exiting vehicle's ability to see vehicles traveling southbound on Ogden Drive, north of the project site. • Street parking on both sides of Ogden Drive, adjacent to the project driveway, limits a driver's ability to see oncoming traffic from both directions. These sight distance concerns create a potential significant safety impact for exiting vehicles. Also, landscaping higher than 3 feet would further restrict sight distance. With the implementation of the following mitigation measure, however, potential sight distance impacts would be reduced to a less than significant level. Sunrise Assisted Living Facility Draft IS/MND MHA Inc. 33 June 2006 CITY OF BURLINGAME Mitigation Measure 3-3: Visible signage shall be posted prohibiting left -turns for vehicles exiting the garage driveway. A "no parking" zone shall be installed between the garage driveway and the loading zone to improve sight distance for exiting vehicles that will be required to turn right. Furthermore, landscaping near the garage driveway shall be maintained not to exceed the three-foot height of the proposed iron fences near the garage entrance/exit. The proposed subterranean parking facility was also reviewed with respect to vehicular circulation. Passenger cars and vans (including larger SUVs and other vehicles as long as 19') would be able to circulate within parking aisles and enter/exit the garage ramp. However, delivery trucks and small buses (approximately 30' long) would have some difficulty negotiating turns and turning into the garage from the entrance ramp. It is probable that delivery trucks and small buses would have to reverse direction or back up to complete turns, which might not be an option if other vehicles are waiting behind to enter/exit the garage or if parking stalls are being utilized. The implementation of Mitigation Measure 3-1 above would limit the garage to passenger vehicles and vans and would require larger vehicles to use the parking area adjacent to Trousdale Drive or to provide for a white curb loading/unloading zone on Trousdale in front of the project entrance. On -Street Parking Trousdale Drive is a 4-lane arterial roadway with parking on both sides near the project site (Figure 12). Ogden Drive is a 2-lane local collector roadway with parking on both sides. Parking along both streets is currently unmarked and unrestricted in terms of time limits. The June 15, 2006 site plan indicates a proposed red curb area directly in front of the project site's building, along the north side of Trousdale Drive. This will result in the elimination of several on -street parking spaces. SOURCE: MHA Inc. 2005 SNVINONMSNTNL CONSULTING, INC. 34 MHA Inc. Sunrise Assisted Living Facility Draft IS/MND June 2006 CITY OF BURLINGAME In addition, as discussed earlier, the eastern side of Ogden Drive is proposed to include an 84-foot passenger loading zone, with no other parking allowed between the project driveway and Trousdale Drive. This will result in further elimination of on -street parking spaces. In total, approximately ten on -street parking spaces are expected to be removed with implementation of this project. Off -Street Parking Fehr & Peers performed research on parking demand at other Sunrise Assisted Living facilities in Northern California. Data collection indicates that the average peak parking demand is approximately 0.43 spaces per room. Using the average peak demand rate from this study, total peak parking demand for the project would be 34 spaces, based on a 79-room facility. Section 25.70.034 of the City of Burlingame's Zoning Code states that for Group Residential Facilities for the Elderly "there shall be provided one parking space for each three residential units where such facilities are designed as separate units; if designed as lodging rooms, one space for each four lodgers, plus one space for each two people employed on the premises." According to Mithun Architects, in an e-mail to the City of Burlingame (Mithun 2005b), the greatest number of "residents" that the proposed facility would accommodate is 95. In addition, the maximum number of employees on the premises would be 22. According to the Zoning Code, this use would require a total of 35 parking spaces. Therefore, the 36 parking spaces that are proposed for the project would meet the minimum supply requirements set forth in the Zoning Code. Currently, Trousdale Drive and Ogden Drive both allow some on -street parking, so additional spaces would be available on the street in the event of any occasional overflow needs. According to the Americans with Disabilities Act (ADA) requirements, at least 2 handicap parking spaces are required where there between 25 and 50 total parking spaces are proposed. One of these spaces must be dedicated to van access, with a ceiling height of 8'-2". The site plan presently meets these requirements. The size of the loading/unloading area (between the two handicap spaces) and access to the elevator is adequate. The proposed subterranean parking facility would be secured with an automatic gate, and accessed only by an entry card or intercom access. Employees would be allowed to use the entry card system, while visitors would use the intercom system. It is possible that visitors will use available on -street parking instead of the garage given the inconvenience of using the intercom system. However, if on -street parking in the area begins to approach full occupancy, it is likely that more visitors will utilize the garage, meaning that on -street parking spillover from the proposed project is likely to occur mainly during times when there is an excess of on -street parking. Parking Facility Dimensions Sections 25.70.020 and 25.70.025 of the City of Burlingame's Zoning Code, Standards for Parking Spaces, state that parking stalls shall be a minimum of 9 feet wide by 20 feet long. Compact spaces must be a minimum 8 feet wide by 17 feet long and labeled "COMPACT CAR". Parking aisles shall be a minimum 24 feet wide where there are perpendicular parking stalls. Columns or similar structures may not protrude more than 6 inches into any parking space. If more than three vehicle maneuvers are needed to enter or exit the space, then the size of the space must be increased to what is deemed as an "acceptable" dimension by the City of Burlingame's Department of Public Works. According to the proposed project site plan, the width and length of all parking stalls (this includes handicap and compact spaces) and aisles are compliant with the City of Burlingame's Zoning Code. Sunrise Assisted Living Facility Draft IS/MND MHA Inc. 35 June 2006 CITY OF BURLINGAME Bicycle and Pedestrian Circulation Currently, there are sidewalk facilities on both sides of Trousdale and Ogden Drives. These sidewalks are 5 feet wide. The site plan indicates that the existing sidewalks surrounding the proposed project site would be widened to between 8 and 10 feet. This would enhance the pedestrian circulation system near the project site. There are two nearby pedestrian crossings on Trousdale Drive. The first is at Magnolia Avenue. This signalized intersection provides controlled crossings on all legs and provides pedestrian access to the nearby retail shops at Burlingame Plaza Shopping Center and medical services at Peninsula Medical Center. This crossing also features an audible signal for the visually -impaired. During a site visit during the morning peak period on September 22, 2005, Fehr & Peers observed that pedestrian signal timing assumes an average walking speed of four feet per second. This is consistent with the minimum requirements suggested by the Manual on Uniform Traffic Control Devices (MUTCD). However, due to the high proportion of senior citizens that were observed walking near the proposed project site and the additional seniors expected as a part of this proposed project, the City may consider retiming the signals to account for a lower pedestrian crossing speed. This is not suggested as mitigation of a project impact, but rather based on observations of existing conditions. Retiming the traffic signals to accommodate a lower pedestrian speed may have secondary effects to traffic operations, however. The City should consider the trade-offs between accommodating the slower speeds of a senior population and the potential traffic impacts. The second nearby pedestrian crossing of Trousdale Drive, at Marco Polo Way, is unsignalized. The intersections of Marco Polo Drive and Ogden Drive with Trousdale Drive function as a four- way intersection, although two of the legs, Ogden Drive and Marco Polo Way, are offset by approximately 90 feet. Eastbound vehicles on Trousdale Drive must stop at Marco Polo Way and westbound vehicles on Trousdale Drive are required to stop at Ogden Drive. The crosswalk is located on the eastern leg of this intersection, at Marco Polo Way. This crosswalk is outfitted with a high -visibility warning sign (seen in Figure 13) that alerts drivers of the nearby pedestrian crossing. As shown in the June 15, 2006 site plan, the project's main pedestrian entrance would be located at the corner of Ogden and Trousdale Drives. The proposed project would enhance sidewalks at its frontage along these streets by nearly doubling the width of the existing sidewalks. The project also proposes to provide a covered ramp/pathway between the white curb loading area on Ogden Drive and the project entrance. Therefore, the project would have a beneficial impact to pedestrian circulation. According to the City of Burlingame's Bicycle Transportation Plan, there are no existing or planned bicycle routes that connect to streets immediately adjacent to the project site. There are currently bike lanes on Murchison Drive and El Camino Real. Although access to these facilities from the project site would not be on designated bicycle facilities, both the Murchison Drive and El Camino Real facilities are close and should not be difficult to reach. Therefore, the proposed project's impact to bicycle circulation is expected to be less than significant. The proposed bicycle parking area adjacent to parking stall number 16 will be sufficient to accommodate the project needs. The project would provide for two bicycle parking racks with a total capacity for 16 bicycles. The garage would be accessible only through secure entry via card or intercom access at the parking garage's driveway gate. Thus, an adequate supply of secure and covered bicycle storage would be provided by the project. 36 MHA Inc.

Noise The noise generated by demolition of the existing building and construction of the project could result in short-term construction -related noise impacts to surrounding receptors such as workers and residents. The cumulative effect of this noise is increased with the simultaneous construction at the Peninsula Medical Center site, particularly if construction occurs at different times of the day. The project would result in some vibration at adjacent properties during demolition and construction. Vibration effects would dissipate over short distances and while they may be felt at nearby buildings, vibration would be minor enough not to jeopardize the integrity of any surrounding buildings or otherwise have any significant effects. Implementation of the following mitigation measures will reduce impacts during construction to less than significant levels. Mitigation Measure 4-1: The project contractor shall implement best management practices for noise reduction, such as muffling and shielding intakes and exhausts of gas powered tools, generators, and other noise -producing equipment. Construction activities shall abide by the construction hours in the Municipal Code and by further restrictions placed on the Peninsula Medical Center, which limit construction hours to 7:00 a.m. to 6:00 p.m. Monday through Friday and 9:00 a.m. to 6:00 p.m. on Saturday. There shall be no construction on Sundays and holidays. Mitigation Measure 4-2: Trucks shall be fully loaded to minimize the number of necessary trips and to further reduce noise related to truck travel. Mitigation Measure 4-3: No radios shall be used by construction personnel on the site at any time. Other noise related to facility operations would include minimal noise from deliveries, and noise from the sump pumps and emergency generator for the site. While the noise level of the generator is rated at 90 to 105 decibels, the generator would be located in the underground parking garage, Sunrise Assisted Living Facility Draft IS/MND MHA Inc. 37 June 2006 CITY OF BURLINGAME and would be soundproofed with a sound trap in the exhaust ducts to reduce noise impacts to residents (Mithun 2005b). The generator would only be used in case of emergency and for testing for 30 minutes once a month. Noise impacts from the generator are therefore not considered to be significant. The project is located in the northwest corner of the San Francisco International Airport Planning Area Boundary and residents could be subject to noise from aircrafts operating on flights to and from the airport (FAA 2005). Noise exposure could represent a significant effect to residents. The North Burlingame/Rollins Road Specific Plan calls out specific measures for any new developments within the Airport Planning Area to mitigate noise. Implementation of the following mitigation measure will reduce impacts from airplane overflights to less than significant levels. Mitigation Measure 4-4: The project applicant shall retain a qualified acoustical engineer familiar with aviation noise impacts to prepare an acoustical study, in accordance with State Title 24 requirements. The acoustical study shall identify methods of design and construction to comply with the applicable portions of the Uniform Building Code Title 24, Appendix 36, Sound Transmission Controls and with the FAA Part 150 Noise Compatibility Program so that construction shall achieve an indoor noise level of 45 dBA, or less, as measured for aircraft noise events (Taken from Chapter 7, Section 2 of the NB/RR Specific Plan). Mitigation Measure 4-5: The project sump pumps and generator shall be located in the underground garage and shall be soundproofed with a sound trap in the exhaust ducts. The sump pump shall be baffled to further minimize noise levels to residents. Project plans shall indicate the location of this equipment and noise mitigation prior to issuance of building permits. 5. Air Quality Demolition of the existing building could potentially generate airborne pollutants such as asbestos and particulate matter (PM10). Demolition activities are regulated by the Bay Area Air Quality Management District (BAAQMD) and require a notification and fee for the permit under Regulation 11, Rule 2 of the BAAQMD Rules and Regulations (BAAQMD 1998). Grading and construction would involve soil disturbance and could result in dust emissions (particulates less than 10 microns [PM,o]) that significantly impact air quality. Construction -related dust emissions would vary from day to day, depending on the level and type of activity, silt content of the soil, and weather. The BAAQMD approach to CEQA analyses of construction impacts is to emphasize implementation of effective and comprehensive control measures, rather than detailed quantification of emissions (BAAQMD 1999). The BAAQMD has identified a set of feasible PM10 control measures for construction activities. Compliance with the following rules and regulations of BAAQMD would reduce potential air quality impacts to less than significant levels. Mitigation Measure 5-1: Demolition of the existing structures shall be required to receive a permit from the Bay Area Air Quality Management District prior to issuance of a demolition permit by the Building Department. All requirements of the permit shall be complied with during construction. Mitigation Measure 5-2: The following notes shall be incorporated on the grading and building plans prior to issuance of grading or building permits, and the measures shall be implemented during construction activities: a. Water all active construction and disturbed areas at least twice daily during dry periods. 38 MHA Inc. Sunrise Assisted Living Facility Draft IS/MND June 2006 CITY OF BURLINGAME b. Cover all trucks hauling soil, sand, and other loose materials or require all trucks to maintain at least two feet of freeboard. c. Pave, apply water three times daily, or apply (nontoxic) soil stabilizers on all unpaved access roads, parking areas, and staging areas at construction sites. d. Sweep daily (with water sweepers) all on -site paved access roads, parking areas, and staging areas at sites of construction activity. Dust, sediment, and debris shall not be washed into the storm drain system. e. Sweep streets daily (with water sweepers) if visible soil material is carried onto adjacent public streets. Dust, sediment, and debris shall not be washed into the storm drain system. f. Excavation and grading activities shall be suspended and dust control measures shall be implemented when winds exceed 25 miles per hour. g. Comply with all required National Pollutant Discharge Elimination System (NPDES) regulations during construction and operations. Traffic related air quality impacts would be less than significant. The project would generate approximately 36 peak hour trips (Fehr & Peers 2005), well below the 100 peak hour trips requiring air quality analysis by the BAAQMD. 6. Hazards and Hazardous Materials A Phase I Environmental Site Assessment (ESA) was conducted for the project site in late 2004 (Kleinfelder 2005). Results of the ESA indicate that previous commercial use of the property involved generation of small quantities of hazardous waste, but did not indicate any documented releases at the site. A groundwater sample collected at the site showed no detectable concentrations of analyzed constituents. The ESA concludes that past and present activities on the site are unlikely to have impacted groundwater at the property. A survey was conducted in 2004 to assess the potential for asbestos and lead paint at the onsite building slated for demolition (Kleinfelder 2004a). Asbestos (2% chrysotile) was detected in joint compounds on approximately 1,500 square feet of the non -asbestos -containing drywall system in the mechanical room of the onsite building. The material was observed to be in good condition at the time of the inspection. Lead -containing paint was also detected on the exterior eave fascia board of the onsite building. The asbestos and lead paint survey report makes several recommendations to ensure appropriate measures are implemented prior to and during demolition of the existing building. Mitigation Measure 6-1 ensures that these recommendations are implemented to reduce risks from potential hazardous materials exposure to less than significant levels. Mitigation Measure 6-1: All recommendations outlined in the December 20, 2004 Asbestos and Lead Paint Survey Report conducted for the property by Kleinfelder shall be implemented prior to and during demolition of the existing building on the site. 7. Geology, Soils and Mineral Resources The applicant's geotechnical consultant performed a feasibility level geotechnical study in December 2004 (Kleinfelder 2004b). The purpose of the feasibility -level geotechnical investigation was to explore and evaluate the subsurface conditions at the site, to identify geotechnical conditions that may impact development of the site, and to discuss general geotechnical guidelines for preliminary planning and conceptual design. Sunrise Assisted Living Facility Draft IS/MND MHA Inc. 39 June 2006 CITY OF BURLINGAME Seismic Impacts The San Francisco Bay Area is considered by geologists and seismologists to be one of the most seismically active regions in the United States. On the basis of current technology and historical evidence, it is reasonable to conclude that during its useful life, the proposed development would be subjected to at least one severe earthquake (magnitude 7 to 8+) that could cause considerable ground shaking at the site. The site would likely also periodically experience small to moderate magnitude earthquakes. Some degree of structural damage could result from seismic shaking, but the risk is reduced, to less than significant levels through adherence to seismic design codes. The site is a level site in the urban environment and would not be subject to seismically induced landslides. The Kleinfelder analysis (Kleinfelder 2004) suggested that the sands encountered between depths of about 30 to 37.5 feet have a high liquefaction potential in one of the borings taken on the property; however, the other boring showed essentially non -liquefiable soils. The potential ground settlement as a result of soil liquefaction could be on the order of 1 inch. This magnitude of settlement could cause significant structural damage unless appropriate structural design is incorporated. Implementation of the mitigation measures outlined below would reduce potential impacts to less than significant levels through geotechnical design requirements. Soils Impacts The near -surface clay soil has a moderate expansion potential. This soil layer extends about 18 to 19.5 feet below ground surface. Mitigation should be incorporated to prevent potentially damaging structural effects associated with building on expansive soils. Soil erosion during demolition and construction would not be an issue at the proposed project site. The area is currently nearly all impervious surfaces from a prior use, and the existing structures and pavement would be demolished. There are no receiving water bodies that could be impacted by erosion and the site is fairly level and located within an urban corridor. The project would be connected to the existing sewer systems located in the utility corridor along Trousdale Avenue. The project would not require an on -site septic leach field septic system. Mineral Resources Impacts There are no mineral resources in the project area that could be impacted by project activities. Potentially significant seismic and soils impacts would be mitigated to less than significant levels through implementation of the following mitigation measures: Mitigation Measure 7-1: The recommendations by Kleinfelder in the Feasibility -Level Geotechnical Study dated December 30, 2004 shall be implemented at each appropriate phase of project construction. As recommended in the feasibility -level investigation, a design level geotechnical investigation shall also be prepared when specific details regarding building type, loads, and dimensions have been formalized. The supplemental investigation shall include additional subsurface exploration, and laboratory testing and engineering analyses. Recommendations of the investigation, particularly related to expansive soils, liquefaction, and groundwater, shall be implemented. Mitigation Measure 7-2: The project shall be required to meet all construction requirements of the California Building and Fire Codes, including seismic standards for structural stability and other related construction considerations. 40 MHA Inc. Sunrise Assisted Living Facility Draft IS/MND June 2006 CITY OF BURLINGAME 8. Hydrology and Water Quality Water Quality Issues The project is not located in proximity to any water bodies or drainage channels. Construction activities would involve ground disturbance and represent a small potential to contribute pollutants into site run-off water. All construction projects must comply with the City of Burlingame NPDES permit requirements to prevent stormwater pollution. Compliance with the City's NPDES permit also requires implementation of construction Best Management Practices (BMPs) and erosion and sediment control measures during all phases of the project's construction (including demolition). The project would follow any other NPDES requirements as applicable. The disturbance area is approximately 43,100 square feet, which is just less than 1 acre, so that a Notice of Intent (NOI) from the State Water Resources Board is not required. The following mitigation measure should also be implemented if work is to be completed during the wet season (October through May) to reduce potential impacts to water quality to less than significant levels. Mitigation Measure 8-1: If the project is constructed during the wet season (October through May), an erosion control and/or sediment control plan, compliant with the City's NPDES (stormwater control) requirements, shall be prepared and implemented, to the satisfaction of the Public Works Department, prior to the onset of the wet season, and maintained throughout the construction period. Mitigation Measure 8-2: All project grading, construction and subsequent operations shall comply with the provisions of the City's NPDES requirements. A Stormwater Pollution Prevention Plan (SWPPP) outlining construction phase and post -construction phase measures to reduce pollutant discharge from the site shall be submitted for review and approval by the Public Works Department prior to issuance of grading or building permits. Drainage and Stormwater Drainage Capacity The project would not create a net increase in impervious surface area. The current site development includes 36,644 square feet of impervious surface area, and after demolition and construction of the proposed project the impervious surface area would decrease to 28,055 square feet. The current office space is surrounded by ground level parking, while the proposed facility would have underground parking, thus reducing some of the proposed impervious surface as compared to the existing situation. The project would not deplete groundwater or alter existing drainage patterns, which currently flow off -site via storm drains. The project falls within the El Portal/Trousdale Watershed. The El Portal/Trousdale Creek watershed drains Burlingame's northwest hillside area from Skyline Boulevard through the Mills Estates residential area, including the Peninsula Medical Center site. The stormwater is carried from El Camino Real through pipelines and surface flow entering the Trousdale and El Portal open channels. Stormwater is pumped from the Rollins Road area from an open ditch along Gilbreth Road to the El Portal channel. Stormwater from the industrial area is collected and pumped to the El Portal channel by the Cowan pump station. The combined stormwater is carried within the El Portal channel through floodgates to San Francisco Bay. The El Portal Creek System chapter of the Citywide Storm Drain Report (2000) states that the existing capacity of the storm drains is adequate for existing development, including pump stations and back-up pumps. The report states that since most properties are substantially covered with impervious surface in the North Burlingame/Rollins Road Specific Plan (in which the proposed site lies), there should be no additional capacity needed for infill development. No significant impacts on stormwater capacity would result from project implementation. Sunrise Assisted Living Facility Draft IS/MND MHA Inc. 41 June 2006 CITY OF BURLINGAME Flooding The project area lies within Zone C, which is defined as "areas of minimal flooding" on the Flood Insurance Rate Map (FEMA 1981). The project area is outside of any 100- and 500-year flood zones and there would little to no risk of flooding at the project site. There are two dams that could impact Burlingame residents in the event of dam failure: Spencer Lake Dam and Crocker Dam (ABAG 2003). Dam failure could result in flooding and potential impact to approximately 2,800 people (City of Burlingame 1975) in these areas, designated as the Burlingame and Crocker Dam failure inundation areas (Wong 2005). The flood zone for dam failure is approximately 1.5 to 2 miles south of the proposed project site in the vicinity of Broadway Avenue. The proposed project would therefore not subject residents to potential flooding resulting from dam failure. Tsunamis are rare in California because of the lack of submarine earthquake faults. The highest tsunami in the past 120 years was 7.4 feet at the Golden Gate resulting in a two -foot run-up along the San Mateo shoreline (City of San Mateo 2000, San Mateo County 1998). The Burlingame coast is somewhat susceptible to minor damage; however, the project area would not likely be affected since it is located about 1 mile from the Bay. Industrial development and U.S. Highway 101 act as a barrier between the development area and the Bay. No significant flooding impacts would result from project implementation. 9. Biological Resources The site has been fully developed and used for office uses since at least 1963. The site is not near any water bodies or riparian habitat. The project is an infill project and does not currently support habitat for any listed or sensitive species. Common species would include squirrels and other rodents and avian species. The land use change from a commercial office building to an assisted living facility would not impact any wildlife species or communities. The only biological resources of concern are on -site trees that may provide nesting opportunities for common bird species such as European starling (Sturnus vulgaris) and mourning dove (Zenaida macroura). The applicant's arborist prepared an inventory of on -site trees and a landscape plan, both of which were used to determine the extent of Protected Tree (see definition below) impacts. The site currently has 13 trees, including: • 5 Olive trees between 24 and 30 inches diameter at breast height (dbh) • 6 Privet trees between 4 and 6 inches dbh • 2 Prune trees at 14 inches dbh All of the existing trees would be removed to accommodate the building. Burlingame Municipal Code Title 11.06.020 ("Urban Reforestation and Tree Protection Ordinance") calls for the preservation of trees and vegetation, which are considered a vital part of the City's character. The City defines a Protected Tree as: • Any tree with a circumference greater than 48 inches when measured 54 inches above natural grade; or • A tree or stand of trees so designated by the city council based upon findings that it is unique and of importance to the public due to its unusual appearance, location, historical significance, or other factor; or • A stand of trees in which the Director of Parks and Recreation has determined each tree is dependent upon the others for survival. 42 MHA Inc. Sunrise Assisted Living Facility Draft IS/MND June 2006 CITY OF BURLINGAME The Municipal Code has provisions to allow for the removal of Protected Trees through the granting of a Protected Tree Removal Permit by the Director of the City of Burlingame's Parks and Recreation Department. Permit conditions would likely require tree replacement or reforestation with the following guidelines: • Replacement shall be three 15-gallon size, one 24-inch box size, or one 36-inch box size landscape tree(s) for each tree removed; • Any tree removed without a valid permit shall be replaced by two 24-inch box size, or two 36-inch box size landscape trees for each tree removed; • Replacement of a tree may be waived by the director if a sufficient number of trees exists on the property to meet all other requirements of the Urban Reforestation and Tree Protection Ordinance; • Size and number of the replacement tree(s) shall be determined by the director and shall be based on the species, location and value of the tree(s) removed; • If replacement trees cannot be planted on the property, payment of equal value shall be made to the City. Such payments shall be deposited in the tree -planting fund to be drawn upon for public tree planting. The five olive trees to be removed would be considered Protected Trees. The proposed landscape plan would provide for many larger size trees to meet the City's tree replacement requirements, and would replace the 13 trees to be removed with approximately 50 trees of 24-inch box or 30- inch box size. The following conditions, however, should be implemented, as recommended by the City arborist, to ensure minimal impacts to existing trees and future trees and landscaping applied to the property. Mitigation Measure 9-1: Tree grates selected by the City and consistent with the North Burlingame/Rollins Road Specific Plan design criteria shall be installed around trees to be installed in sidewalk areas on Trousdale Drive, per City guidelines. Mitigation Measure 9-2: The project landscaping plan shall be reviewed and approved by the City Arborist prior to issuance of any grading and/or building permits, and all landscaping shall be installed prior to scheduling final inspection. This work shall include installation of all trees within sidewalk areas and the installation of the curb, gutter and sidewalk. With the implementation of the above mitigation measures, potential biological impacts would be reduced to a less than significant level. 10. Cultural Resources The project parcel has been in a developed condition since prior to 1963. Former building occupancy was by Pacific Telephone and Telegraph Company and more recently by State Farm Insurance. The existing building was constructed in 1956, and has no local significance (Hurin 2005b). The structure does not appear eligible for listing in the California Register of Historic Resources. As such, the structure is not considered to be an historic resource as defined in Section 21084.1 of CEQA. Any archaeological or historic, cultural, or ethnic sites, which may have been in or near the project location, were disturbed or destroyed by previous development prior to this proposal. Should any cultural resources be discovered during construction, work would be halted until they are fully investigated to prevent significant impacts to undiscovered resources. The following mitigation measure will assure that potential impacts are reduced to a less than significant level. Mitigation Measure 10-1: Grading and/or construction shall stop immediately if archaeological or paleontological resources are uncovered during grading or other onsite excavation activities. Work shall not resume in the area of the discovery until a qualified Sunrise Assisted Living Facility Draft IS/MND MHA Inc. 43 June 2006 CITY OF BURLINGAME archaeologist (or other equivalent specialist) provides an evaluation of the significance of the resources and what can be done to preserve them. Disposition of the identified resource shall be implemented compliant with State law prior to further work within 50 feet of the location of the resource. 11. Population and Housing Burlingame's population of 28,158 in 2000 is only 3 percent larger than its 1970 population. The Association of Bay Area government's projections anticipate, however, that the City would continue to grow, reaching a population of 31,500 by 2010. With the turn toward growth, there has been a decrease (from 23.6% in 1990 to 19.1 % in 2000) in the number of residents over 65 years of age. The year 2000 population over 65 years old in Burlingame is 4,287. Currently there are 521 nursing home beds in Burlingame: 60 licensed spaces in small group assisted living facilities, 90 assisted living units in a retirement home, and 371 nursing home/convalescent care licensed beds. Two of these facilities have been built since 1994 and provide 72 licensed beds for Alzheimer patients. These facilities support the needs of the city's more fragile, disabled elderly and younger residents who might need transitional assistance from the hospital. The proposed project would provide 79 units of senior housing with 95 beds. Because these units are for senior assisted care, they would not count towards Burlingame's share of regional housing needs, according to the State's current definition of a residential unit. However, the project does comply with Burlingame's General Plan and Housing Element goals to encourage special purpose housing (Goal D: Encourage Special Purpose Housing). The increase of approximately 95 new residents at maximum occupancy of the facility is less than 2 percent of the City's estimated growth through 2010. The project would require demolition of an existing office building, eliminating potential jobs associated with the office space. The facility would, however, provide 23 full time and 13 part time employee positions. The project would cause a reduction in office space of 16,000 square feet; the proportion of this loss to overall office space in Burlingame, however, would not generate a significant impact on employment in the City. The project area is also currently zoned for commercial use as well as for senior living facilities, and the project therefore provides an appropriate alternative use of the site. The project would not create significant impacts related to population, housing or job growth. 12. Public Services Fire Protection The Burlingame Fire Department is part of the consolidated San Mateo Central County Fire District, which serves Burlingame and the Town of Hillsborough. There are no boundaries between stations (meaning all stations can serve any location). Calls are dispatched from Redwood City to the nearest available station for land line phones and from either Burlingame Police or the Highway Patrol for cell phone emergency calls (Yballa 2005). In most cases, a fire engine can be on the scene of an emergency within 5 minutes. The three nearest stations and locations include: • Station 34: 799 California Drive (2.0 miles from proposed project site) • Station 35: 2832 Hillside Drive (1.9 miles from proposed project site) • Station 36: 1399 Rollins Road (2.0 miles from proposed project site) Each station has an engine with at least three personnel assigned to it. The fire station on California Drive has two engines, one of which is a 105-foot aerial truck with a minimum of three 44 MHA Inc. Sunrise Assisted Living Facility Draft IS/MND June 2006 CITY OF BURLINGAME personnel assigned to it. There is at least one chief officer on duty at all times at each station (City of Burlingame 2005a). The project would add a maximum of 95 residents in a new four-story building. Proper fire precautions must be incorporated into the project to reduce the chance of a fire and reduce the impact if one were to occur. Standard Fire Department review and Uniform Fire Code regulations would require compliance with the Fire Code for this type of use, and would assure that impacts are not significant. Emergency Medical Services American Medical Response is the County contracted ambulance service. The nearest emergency medical clinic is located at 1606 Rollins Road, and the Peninsula Medical Center emergency entrance is directly across Trousdale from the site. The Fire Department would respond to ambulance calls in many emergencies. All fire engines are staffed with at least one paramedic. The Burlingame Fire Department can often put a paramedic on the scene much faster than the private ambulance company. The proposed project would be expected to incrementally add to the demand for emergency medical services. The expected age of the facility's residents may translate to a higher frequency of calls for service than might be expected for a similarly sized conventional multifamily residential development. The fact that the facility would be staffed 24 hours per day may offset potential calls for service, because of the ability of the staff to address non -critical or non -emergency needs that might otherwise result in a call for service. The facility would be located across Trousdale Drive from the emergency entrance to the Peninsula Medical Center, which would expedite emergency treatment of residents. The addition or relocation of up to 95 residents within a city of approximately 28,000 citizens would not require the expansion of medical services Police Protection The City of Burlingame Police Department provides police protection. Burlingame has a lower crime rate than the average for a U.S. city (City-data.com 2005). Because of the nature of the project as a senior assisted living facility, increases in police protection needs, when compared to the prior office use, are not expected. Schools Implementation of the proposed project would have no impact on schools because of the age of the residents at the facility and the fact that school aged children would not be residents at the facility. Parks and other Public Facilities There are approximately 17 parks and playgrounds in the City of Burlingame (City of Burlingame 2005b). Use of these facilities would be limited because of the reduced mobility of residents of the facility. Many of the residents' activities would be provided directly by the facility operator. Up to 23 full-time and 13 part-time employees would be needed to operate the facility. This small number of employees, the limited opportunity for use of recreational facilities, and the lower mobility of residents would result in little or no impacts on local parks or any other public facilities. 13. Recreation There are approximately 17 parks and playgrounds in the City of Burlingame (City of Burlingame 2005b). Use of these facilities would be limited because of the services provided to the residents Sunrise Assisted Living Facility Draft IS/MND MHA Inc. 45 June 2006 CITY OF BURLINGAME on -site, the reduced mobility of residents of the facility, and the limited free time of the staff. There would be no significant impacts to public recreational facilities. The project includes the construction of recreational facilities within the building. The facility is designed to be a self-contained community with several indoor recreational options in activity rooms, card rooms, media rooms, craft rooms, dining and living rooms, etc. There is also an outdoor terrace to allow residents easy access to outside areas. The staff has their own lounge for breaks. Since these recreational outlets are located within or as a part of the building, they would not result in any physical effects to the environment, other than in conjunction with the overall building program. 14. Utilities Stormwater Facilities The project would use the existing storm drain system, connecting to an existing 48-inch Reinforced Concrete Pipe (RCP) storm drain line in Trousdale Drive near the southeast corner of the site. The current development on the site includes impervious surfaces over approximately 85 percent of the site. The project would reduce the impervious surfaces to approximately 64 percent of the project site. Drainage is generally directed on the surface or through storm drains to the southeast corner of the site, where it connects to the City's storm drain. To assure that drainage impacts do not result from storm flows, however, the following measure should be implemented. Mitigation Measure 14-1: The applicant shall submit a site drainage plan to the City Engineer for review and approval prior to issuance of grading or building permits. The plan shall show all site drainage flowing to the street level by gravity. The plan shall show the direction and volume of drainage and shall confirm that no drainage enters neighboring properties. Groundwater from the foundation perimeter drain shall be directed to onsite landscaping/swales, with excess water drained to the City storm drain system. Sewer Facilities All new utility connections to serve the site and that are affected by the development would be installed to meet current code standards. New sewer laterals from the sewer main to serve the new structure would be checked and replaced if necessary. There is an existing 12-inch sanitary sewer line in Trousdale Drive. The project would include installation of a 6-inch sewer lateral to this connection. The sewer system in Burlingame is gravity fed to lift stations located in the industrial sections of the city, then to the Treatment Plant at 1103 Airport Boulevard. Wastewater generation for the project is estimated at 3,496 gallons per day (Mithun 2005b). Wastewater generation for the existing office building is estimated at 945 gallons per day (Mithun 2006), based on standard engineering calculations for an office building of this size. Actual water usage, however, based on historical water consumption records (Hurin 2006) indicate that the average wet season demand for the months of October -April of 2001-02, 2002-03, and 2003-04 was approximately 754 gallons per day. Wet season water use tends to better approximate sewer demand since there is considerably less irrigation during those months. The 2004-05 and 2005-06 months were not included since building occupancy was sporadic during those periods. Based on the 754 gallons per day for the existing building, the net increase in sewer demand for the proposed project would be 2,742 gallons per day (3,496 — 754 gallons per day). The capacity of the 12-inch main in Trousdale Drive is under review as part of a larger sewer and water study by the Peninsula Medical Center project team. A 6-inch main running in a southerly direction on the east side of the site and serving new residential development also contributes to 46 MHA Inc. Sunrise Assisted Living Facility Draft IS/MND June 2006 CITY OF BURLINGAME the 12" main and will be considered in the analysis (Nakashima 2006). Mitigation Measure 14-2 will require the applicant to prepare a sewer study to assess the additional impact of the Sunrise project and determine if the added sewage flows can be accommodated by 1) the existing line in Trousdale Drive or 2) the upgraded line if required for the hospital project. If the analysis determines that the 12" main requires upgrading, the Sunrise project will be required to contribute to the improvements. Mitigation Measure 14-2: The applicant shall prepare and submit to the City Engineer a sewer study that assesses the impact of this project to determine if the additional sewage flows can be accommodated by 1) the existing line in Trousdale Drive or 2) the upgraded line (if required) for the hospital project. If the analysis results in a determination that the 12" main requires upgrading, the applicant shall contribute the project's fair share, as calculated by the City Engineer, of funding for the improvements. According to the North Burlingame/Rollins Road Specific Plan (p. 49), "the aggregated change of land uses in the Specific Plan area will create lesser demands on water supply and sanitary sewer capacities than the existing uses, so changes in infrastructure or demand on water supply caused by the plan are not anticipated)." Therefore, with the verification of capacity or upgrade of the 12" line in Trousdale Drive, the project will not result in a significant impact on sewer capacity or cause significant environmental effects from the expansion of existing facilities. Water Supply The applicant's engineer has estimated water use for the project at a maximum of 3,796 gallons per day (Mithun 2005b). The City of Burlingame supplies water service to residents. The City's sole source of potable water is the San Francisco Public Utilities Commission system. The nearest water main is in Trousdale Drive bordering the site. In November of 2000, the City of Burlingame adopted an Urban Water Management Plan. The plan includes the City's water consumption needs and anticipated supplies to accommodate current needs and future growth. The Plan indicates that projected growth anticipated by the Association of Bay Area Governments (ABAG) population projections for Burlingame and development anticipated in the Housing Element Update can be accommodated by the existing system and allotments from the Hetch Hetchy system. Growth related to the project would be minimal and would fall within the ABAG projections and Housing Element update projections; therefore no new water entitlements would be required. Solid Waste The current solid waste provider is Allied Waste. Allied Waste hauls waste collected in Burlingame to Ox Mountain Landfill. Construction activities would generate waste during the construction phase. The general contractor is required to recycle construction debris and to reduce the waste stream. Construction debris is sorted and transported separately. After reclamation and recycling from demolition, solid waste generated during operation of the project would be typical of living facility use, and would not be considered substantial. The project's 95 residents plus 25 employees would generate approximately 528 pounds of trash per day. This is not considered an unusual amount of garbage and is a less than significant impact. Electricity and Natural Gas Electricity and natural gas would be provided by Pacific Gas & Electric (PG&E). Capacity and facilities exist to connect to PG&E's system. Potential impacts on utility systems are therefore not considered significant.

A conditional use permit is required for a group residential facility for the elderly in the TW zoning district. The proposed assisted living facility will contain a total of 79 units. The main entrance to the facility is proposed at the corner of Trousdale and Ogden Drive. A second entrance is provided off Ogden Drive. The first and second floors will contain assisted living units and related common activity and support services. The third floor will contain suites for memory -impaired residents. The fourth floor is similar to the third floor but with lower staffing requirements and increased amenities for residents. The assisted living units consist of one -bedroom, two -bedroom and a "Denver" unit which can accommodate one or two persons. The proposed facility will contain 37 one - bedroom units, 20 two -bedroom units and 22 "Denver" units. Typical units range in size from 395 SF to 635 SF. The proposed exterior will include stucco walls, vinyl clad double -hung wood windows, stained wood windows and doors at first floor public places, and a concrete tile "terra cotta" roof. On the first floor, a decorative railing above a low retaining wall is proposed along Ogden and Trousdale Drive. At the main entrance to the facility, located at the corner of the building at Ogden and Trousdale Drive, a metal and glass canopy is proposed to clearly identify the entrance. The canopy extends out from the face of the building and its edge would be located 3'-0" from the property line along Ogden Drive and on the property line along Trousdale Drive. A front setback variance is required for the proposed canopy on the first floor along Ogden Drive (3'-0" proposed where 10'-0" is required for a length of 48'-0"). A side setback variance is required for the proposed canopy on the first floor along Trousdale Drive (0'-0" proposed where 10'-0" is required for a length of 48'-0").

A conditional use permit is required for a group residential facility for the elderly in the TW zoning district. The proposed assisted living facility will contain a total of 79 units. The main entrance to the facility is proposed at the corner of Trousdale and Ogden Drive. A second entrance is provided off Ogden Drive. The first and second floors will contain assisted living units and related common activity and support services. The third floor will contain suites for memory -impaired residents. The fourth floor is similar to the third floor but with lower staffing requirements and increased amenities for residents. The assisted living units consist of one -bedroom, two - bedroom and a "Denver" unit which can accommodate one or two persons. The proposed facility will contain 37 one -bedroom units, 20 two -bedroom units and 22 "Denver" units. Typical units range in size from 395 SF to 635 SF. The proposed exterior will include stucco walls, vinyl clad double -hung wood windows, stained wood windows and doors at first floor public places, and a concrete tile "terra cotta" roof. On the first floor, a decorative railing above a low retaining wall is proposed along Ogden and Trousdale Drive. At the main entrance to the facility, located at the corner of the building at Ogden and Trousdale Drive, a metal and glass canopy is proposed to clearly identify the entrance.
