Description of the Project: The proposal is to construct a new two and one half story single family dwelling with an attached garage at 2838 Adeline Drive, zoned R-1. The proposed house would cover 16.3% (4,343 SF) of the 26,576 SF lot, where 40% (10,630 SF) is the maximum lot coverage allowed. The house would have a total floor area of 7,797 SF (0.29 FAR) where 8,000 SF (0.30 FAR) is the maximum allowed. There would be three covered attached parking spaces provided for this five bedroom house. The applicant is seeking design review for a new single family dwelling and a special permit for an attached garage. The subject property is currently vacant and heavily vegetated with shrubs and trees, predominantly Blue Gum Eucalyptus. There are also Coast Live Oaks, California Bay Laurel and Acacia on this site. As part of the development of this parcel the applicant will be removing 40 trees from this site,15 of which are of protected size. Burlingame municipal code section 11.06.020(f) defines a protected tree as any tree with a circumference of 48 inches or more when measured 54 inches above natural grade. The lot has a slope of between 21% and 22%. Code section 25.70.025(2)(d) states that the maximum driveway slope shall not exceed 15 percent. The project includes grading and building retaining walls on this slope in order to build an access driveway to the more level portion of the lot where the proposed house will be constructed. This project is subject to CEQA review because of the removal of the trees and the slope on the lot. 9. Surrounding Land uses and Setting: The property is located in the Burlingame hills. It is currently a vacant lot with a slope of between 21 % and 22%. This subject property, along with the property directly across the street were both once part of the larger Sisters of Mercy property, which was annexed into the City in the 1970's. The two properties extended to the west from the main campus, and are surrounded by single family residential properties that are located in unincorporated County of San Mateo. The subject property and surrounding properties are heavily vegetated with trees and shrubs. 10. Other public agencies whose approval is required: There are no permits required from other public agencies. However, San Mateo County is a responsible agency. ENVIRONMENTAL FACTORS POTENTIALLY AFFECTED: The environmental factors checked below would be potentially affected by this project, involving at least one impact that is a "Potentially Significant Impact" as indicated by the checklist on the following pages. Land Use and Planning X Biological Resources X Aesthetics Population and Housing Mineral Resources Cultural Resources X Geology and Soils Hazards & Hazardous Recreation Materials X Hydrology & Water X Noise Agricultural Resources Quality Air Quality Public Services X Mandatory Findings of Significance Transportation/Traffic X Utilities and Service Systems DETERMINATION: (To be completed by the Lead Agency). On the basis of this initial evaluation: I find that the proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION will be prepared. I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because revisions in the project have been made by or agreed to by the project proponent. A MITIGATED NEGATIVE DECLARATION will be prepared. X I find that the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. I find that the proposed project MAY have a " potentially significant impact" or " potentially significant unless mitigated" impact on the environment, but at least one effect (1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and (2) has been addressed by mitigation measures based on the earlier analysis as described on attached sheets. An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that remain to be addressed. I find that although the proposed project could have a significant effect on the environment, because all potentially significant effects (1) have been analyzed adequately in an earlier EIR or NEGATIVE DECLARATION, and (2) have been avoided or mitigated pursuant to that earlier EIR or NEGATIVE DECLARATION, including revisions or mitigation measures that are imposed upon the proposed project, nothing further is required.

The Zoning Code requires a minimum lot size of 10,000 SF for lots annexed to the City of Burlingame after May 31, 1960, where the subject property is 26,576 SF in area. The Zoning Code allows one unit per lot in this area. The project is subject to single family residential design review. The general plan would allow a density of 8 units to the acres and the application is for 1 unit to a half acre. Therefore, this proposal is consistent with the General Plan and zoning requirements. The subject property was once part of the Sisters of Mercy property, which abuts the subject property on the northeast side. The entire Sisters of Mercy campus was annexed from the San Mateo County jurisdiction into the City of Burlingame in the 1970's. The surrounding properties are developed with single family residences, all of which are within unincorporated San Mateo County. The lot slopes between 21% and 22% from front to rear. Code Section 25.70.025(2)(d) states that the maximum driveway slope shall not exceed 15 percent. The project includes grading and construction retaining walls in order to construct build an access driveway to the more level portion of the lot where the proposed house will be constructed. The maximum slope on the driveway will be 18%. The proposed residence conforms to all measurable requirements of the zoning code; however a special permit is required for an attached garage. The Planning Commission determines compliance with design review criteria. Population and Housing Summary: This site and the surrounding area are planned for low -density residential uses. The proposed infill residential development conforms to the City of Burlingame General Plan and Zoning Code regulations and does not represent any alteration to the planned land use in the area. The project is consistent with the City's Housing Element. The proposed project will create more housing by adding another dwelling unit where there is currently a vacant parcel. Geologic Summary: The site is located in the Burlingame Hills in a semi -urban setting, with most of the lots in vicinity over 10,000 SF in area. The subject property has a steep slope at the front of the property and then gently slopes and levels off toward the rear. It is approximately 110 feet wide by 247 feet deep. The average difference in elevation from the top of the lot to the rear of the lot is 53 feet. The first third of the lot has a 2 1. 1 to 22.1% slope. The site is approximately 3 miles northwest of the San Andreas Fault, and 17 miles northwest of the Hayward Fault, but is not within the Alquist-Priolo zone. There are no known faults on the site. The seismic exposure will be reduced with the incorporation of seismic construction requirements of the California Building Code, 2001 Edition. The USGS maps designate the soil type as br, which is bedrock that varies from well -consolidated sediments to deeply weathered igneous intrusive and extrusive rocks. Under seismic conditions this site is categorized in C zone, and would experience very strong shaking. However, most Burlingame soils are reasonably stable. The applicant's soils report states that soil borings on the property confirm that the site is underlain by colluviums fill over sandstone bedrock. Because of the strong subsurface materials and the absence of subsurface flows, it is unlikely that liquefaction of the foundation soils would occur. The soils report notes that there is some natural overburden material on this steeply sloping site, with some potential for creep. It is suggested that the foundation is to be of a drilled pier and grade beam design, penetrating into the underlying sandstone bedrock material a minimum of 8 feet, with an expected overall depth of 18 feet with a minimum of a 16" diameter. Due to the creep potential on this site the soils engineer states that the piers 11 Initial Study Summary 2838 Adeline Drive shall be designed to resist a lateral active pressure of 50 pounds per cubic foot acting on the top five feet of the pier. There will be no pile driving for the piers. The piers will be drilled and then poured in place. As per San Francisco Bay Regional Water Quality Control Board, all clearing and earth moving activities shall only occur during dry weather, April 15 through November 14. This time line is also suggested in the soils report for this project. To commence construction the site would first need to be cleared of vegetation and shrubs to allow access for the construction of the retaining walls. The retaining walls would be erected prior to the removal of the trees on -site and would increase slope stability. Once the retaining walls are constructed it would allow stabilization for the driveway construction. The construction of the retaining walls and the driveway would then provide easier access for the removals of the trees. While excavation occurs, the temporary shoring shall be required to prevent movement of exposed materials. All excavation and slope cutting will require temporary shoring to be analyzed by an engineer. The retaining walls shall also be designed to resist lateral earth pressure and additional lateral pressures caused by surcharge loads applied at the ground surface behind the walls. The soils reports calls out that any imported fill materials on the site shall be non -expansive materials with a Plasticity Index of 12 or less. The retaining walls would have a sub -drain system consisting of a four inch diameter perforated pipe bedded in drain rock wrapped with filter fabric to a height of two-thirds the height of the wall. The walls would be backfilled and compacted to at least 90 percent relative compaction. Retaining walls shall be waterproofed. The project will be required to meet all the requirements, including seismic standards, of the California Building and Fire Codes, 2001 Edition, as amended by the City of Burlingame, for structural stability. Mitigation: • That there shall be no pilling driving as part of this project. • That the house foundation be a drilled pier and grade beam design, penetrating into the underlying sandstone bedrock material a minimum of 8 feet, with an expected overall depth of 18 feet with a minimum of a 16" diameter. • That the piers shall be designed to resist a lateral active pressure of 50 pounds per cubic foot acting on the top five feet of the pier. • That all clearing and earth moving activities shall only occur during dry weather only, April 15 through November 1, as per the San Francisco Regional Water Quality Control Board and that all NPDES and STOPPP requirements shall be met on the site at all times during construction • That at the commencement of construction, the retaining walls shall be erected prior to the removal of the trees on -site and prior to the grading of the driveway. • That no demolition or grading shall occur until the City Arborist has reviewed and approved all required arborist reports; and during excavation and slope cutting temporary shoring shall be required to prevent movement of exposed materials. All shoring shall be analyzed by licensed engineer, and shall be approved by the City Engineer prior to any construction. 12 Initial Study Summary 2838 Adeline Drive • That the retaining walls shall be designed to resist lateral earth pressure and additional lateral pressures to the levels required by a license soils engineer and approved by the City; caused by surcharge loads applied at the ground surface behind the walls. • That all imported fill materials on the site shall be non -expansive materials with a Plasticity Index of 12 or less. • That all retaining walls shall have a sub -drain system consisting of a four inch diameter perforated pipe bedded in drain rock wrapped with filter fabric to a height of two-thirds the height of the wall. • That all retaining walls shall be backfilled and compacted to at least 90 percent relative compaction. • That all retaining walls shall be waterproofed. • That the project shall be required to meet all the requirements, including seismic standards, of the California Building and Fire Codes, 2001 Edition, as amended by the City of Burlingame, for structural stability; an the construction plans and design shall be approved by the Building Department and all necessary permits issued before any grading, tree removal or construction occurs on the site. Water Summary: This project is an in -fill development project with a new residence on a currently vacant parcel. The subject property is not adjacent to a waterway. The project site is located in Flood Zone C, which is outside the 100-year flood zone. During the soils investigation by the applicant's engineer it was noted that there was some erosion evident from Adeline Drive, but the runoff has ceased due to the construction of a berm at Adeline Drive. No sub -surface flows were found on the site, but maybe present during winter storm episodes. Because of the strong subsurface materials and the absence of subsurface flows, it is unlikely that liquefaction of the foundation soils would occur on this site. There is an existing 3 inch screwed steel waterline in the general vicinity. However because there is no existing water service to this site the applicant had the Burlingame Fire Department perform a flow test on the two nearest hydrants to the subject property, located in front of 2825 and 2839 Adeline Drive in order to determine if there adequate water pressure to supply the domestic water supply for a new single family dwelling on this line. Based upon the results from this test and the calculations done by the applicant's plumber, there is enough pressure on this line to supply the new dwelling without having a potentially significant impact on pressure to existing dwellings in the area. The test results clearly indicate that this line is not large enough to serve the domestic water line and the fire sprinkler system. As an alternative option the application will be supplying water to the fire sprinkler system using the water from the proposed swimming pool that will be located at the rear of the house. The pool will have approximately 36,000 gallons of water when filled. If activated, the pool water will be fed to the fire sprinkler system by a suction pump that will powered from the main electrical service, and will also be connected to the back up generator. The City of Burlingame's Fire Marshal has accepted this alternative as an adequate means of water supply for the fire sprinkler system. 13 Initial Study Summary 2838 Adeline Drive The project will need to have an erosion and sedimentation control plan that describes BMPs, (best management practices) that will be implemented for storm water management and erosion control. This plan will need to be show and describe what type of erosion control measures will be administered to prevent soil, dirt and debris from entering storm drain systems and how these measures will be maintained. These measures may include, but not be limited to, the following; sediment basins or traps, berms, silt fences, straw bale, storm drain inlet protection soil blankets, and covers for soil stock piles. These measures need to be installed to stabilize denuded areas and to maintain temporary erosion controls and sediment control continuously until permanent erosion controls have been established. The site plan should clearly show the property lines; existing and proposed topography; areas to be disturbed by cut and fill; the location for soil storage and disposal areas; and existing vegetation and sensitive areas to be protected. All construction materials and waste, including solid wastes, paints, concrete, petroleum products, chemicals, wash water or sediment, shall be stored, handled and disposed of properly to prevent the discharge of all potential pollutants into stormwater. This information should be noted on the erosion and sedimentation control plan. No vehicles or equipment shall be cleaned, fueled or maintained on -site, except in designed areas in which runoff is contained and treated, and this area should also be clearly shown on the plan. All off -site and on - site runoff shall be diverted around exposed construction areas. How this will be accomplished must be shown on plan and approved by the City prior to commencement of any grading or construction activity on the site. Mitigation: • That the applicant shall connect with the existing 3 inch screwed steel water line on Adeline Drive for the domestic water supply for the new single family dwelling, in accordance with the City of Burlingame Public Works standards. • That the applicant shall use the swimming pool on -site for the water supply for the residential fire sprinkler system, with a suction pump that will powered from the main electrical service, and will also be connected to the back up generator, all system details shall be reviewed and approved to be in accordance with standards acceptable to the City of Burlingame's Fire Marshal prior to issuance of a building permit. • That the applicant shall submit an erosion and sedimentation control plan describing BMPs (Best Management Practices) to be used to prevent soil, dirt and debris from entering the storm drain system; the plan shall include a site plan showing the property lines, existing and proposed topography and slope; areas to be disturbed, locations of cut/fill and soil storage/disposal areas; areas with existing vegetation to be protected; existing and proposed drainage patterns and structures; watercourse or sensitive areas on - site or immediately downstream of a project; and designated construction access routes, Staging areas and washout areas; this plan must be approved by the City Engineer, Public Works Department prior to any grading or construction work on the site. • That the erosion and sedimentation control plans should include notes, specifications, and/or attachments describing the construction operation and maintenance of erosion and sediment control measures, including inspection frequency; methods and schedule for grading, excavation, filling clearing of vegetative cover and mulch, including methods and schedules for planting and fertilization; and provisions for temporary and permanent irrigation. 14 Initial Study Summary 2838 Adeline Drive • That off -site runoff shall be diverted around the construction site and all on -site runoff shall be diverted around exposed construction areas. • That methods and procedures such as sediment basins or traps, earthen dikes or berms, silt fences, straw bale dikes, check dams storm drain inlet protection soil blanket or mats, and covers for soil stock piles to stabilize denuded areas shall be installed to maintain temporary erosion controls and sediment control continuously until permanent erosion controls have been established. • That all construction materials and waste, including solid wastes, paints, concrete, petroleum products, chemicals, wash water or sediment, shall be stored, handled and disposed of properly to prevent the discharge of all potential pollutants into stormwater. • That no vehicles or equipment shall be cleaned, fueled or maintained on -site, except in designed areas which runoff is contained and treated. Air Quality Summary: The proposed application is for one single-family dwelling on an existing vacant site. While this project will accommodate people for habitation where the previous use was as open space and access to a water tank for use by the Sisters of Mercy campus, the change in emissions is insignificant. The subject property is zoned for low -density residential development and with proper adherence to regional air quality requirements during construction, the proposed project will not create any deterioration in the air quality or climate, locally or regionally. There is no demolition of existing structures on this site because it is vacant, so no permits are required from the Bay Area Air Quality Management District. Mitigation: • That dust control should be implemented where required during grading, which includes spraying cut areas where there is significant particulate matter created by soil disturbance. Transportation/Circulation Summary: The site is on Adeline Drive, a collector street that provides access to El Camino Real, a regional arterial. This project will not create a permanent substantial increase in the traffic generation in the area. All arterial, collector, and local roadway systems in the City have the capacity to accommodate any incremental traffic or trip generation produced by the proposed increase of one dwelling for the current proposal. The proposed single-family dwelling meets the on -site parking requirement established in the zoning code. Adeline Drive is 50 feet wide, but does not have sidewalk, curbs or gutters. There is a narrow area that provides a vehicular pull out, however vehicular access will be limited to this site until the driveway is constructed. The construction vehicles required for the proposed project may create a temporary impact on public safety, access, and circulation. Once the driveway is constructed there will be direct access onto the site for construction vehicles and tree removal machinery. Biological Resources Summary: The site is currently vacant with a large concentration of trees. Most of the trees on the property are Blue Gum Eucalyptus, but there are also Coast Live Oaks, California Bay Laurel and Acacia. The applicant has submitted an arborist report that was reviewed and found acceptable by the City Arborist. 15 Initial Study Summary 2838 Adeline Drive As part of this proposal the applicant is proposing to remove all of the Eucalyptus on the site. The trees are proposed for removal because they are within the construction area for the proposed house and driveway. The Blue Gum Eucalyptus are also a non-native species that are very oily and can pose extreme fire danger. They usually serve as a windbreak or screen barrier, but they are not acting as either on this site. The arborist notes that the age and size of the trees make them a poor choice for a landscape tree and as they often shed limbs during high winds, which is another reason not to locate these trees near residences. As observed on the site, they are also overshadowing many of the desirable native Coast Live Oaks on this property. The City Arborist has stated that the after cutting the Eucalyptus that the stumps need to be ground immediately. Immediately after the removal of the trees on this site or no later than 4 weeks after the cutting of the trees, either permanent or temporary measures also needs to be installed to prevent erosion and soil instability on the slope. The arborist's report submitted by the applicant notes that the existing Coast Live Oaks on this property are in overall good health. Tree protection measures must be implemented during construction to protect the Oaks and other trees on site to prevent potentially significant impacts to the health of the trees. These measures include covering the root zones with 4 inches of mulch, and covering them with a layer of plywood to reduce soil compaction around the tree. It is also recommended that the trunks of the oak trees be wrapped with wooden planks with highly visible orange netting wrapped around the planks to attached them to the trunk rather than using nails or screws. If there are low limbs that will be in the way of construction traffic the arborist's recommends trimming the limbs rather than having them ripped off. The arborist states that the Oak trees will benefit from structural pruning and a lowering of the soil grade at the root collar. During construction all clearing limits, easements, setbacks, sensitive or critical areas, buffer zones for trees, and drainage courses are should be clearly delineated with field markers or fencing. The adjacent properties and undisturbed areas should also be protected from construction impacts with vegetative buffer strips, sediment barriers or filters, dikes or mulching. All of tree protection measures should be taken prior to the beginning of tree removal activities, grading and construction and issuance of a building permit. In accordance with the City's Reforestation Ordinance, each lot developed with a single-family residence is required to provide a minimum of 1, 24-inch box -size minimum, non -fruit tree, for every 1,000 SF of living space. The proposed landscape plan for the project complies with the reforestation requirements. The arborist also recommends a reforestation program for this site as part of this project. The landscape plans indicate that the following trees will be planted in 24" box size: 3 Japanese Maples, 5 Southern Magnolias, 7 Coast Live Oaks,10 Carolina Cherry Laurels, 3 Olive Trees, 1 Jacaranda, and 4 Pittosporum Undulatum. Mitigation: • That within 24 hours after cutting down the Eucalyptus trees on the site, the stumps shall be ground. • That the site shall be terraced, either permanently or temporarily, immediately after the removal of the trees on this site and no later than 4 weeks, after cutting the trees to prevent erosion and soil instability on the slope. • That the root zones of Oak trees to remain on -site shall be covered with 4 inches of mulch, and then covered with a layer of plywood to reduce soil compaction around the tree. • That the trunks of the Oak trees shall be wrapped with wooden planks with highly visible orange netting wrapped around the planks to attached them to the trunk, no nails or screws shall be used for attachment. 16 Initial Study Summary 2838 Adeline Drive • That low limbs, identified and marked by a licensed arborist, that will be in the way of construction traffic shall be trimmed as directed by a licensed arborist prior to construction to avoid having them ripped off by construction vehicles. • That all clearing limits, easements, setbacks, sensitive or critical areas, buffer zones trees, and drainage courses are clearly delineated with field markers or fencing installed under the supervision of a licensed arborist and inspected by the City Arborist; and that adjacent properties and undisturbed areas shall be protected from construction impacts with vegetative buffer strips, sediment barriers or filters, dikes or mulching as designed by and installed with the supervision of a licensed arborist to standards approved by the City Arborist. • That all of tree protection measures shall be taken prior to beginning any tree removal activities, grading or construction on the site. • That a licensed arborist, hired by the applicant, shall inspect the construction site once a week or more frequently if necessary and certify in writing to the City Arborist and Planning Department that all tree protection measures are in place and requirements are being met. • That in accordance with the City's Reforestation Ordinance a reforestation program for this site shall include planting the following 24" box size trees: 3 Japanese Maples, 5 Southern Magnolias, 7 Coast Live Oaks, 10 Carolina Cherry Laurels, 3 Olive Trees, 1 Jacaranda, and 4 Pittosporum Undulatum at the locations shown on the approved landscape plan prior to scheduling the final inspection. • That a licensed arborist shall provide a post -construction maintenance program to the property owners with instructions on how to maintain them and identify warning signs of poor tree health; the property owners shall be responsible for the maintenance of the trees for 3 years after construction is finalled by the City and shall bear the penalty fee should the trees not survive the 3-year period; the trees shall be inspected for compliance twice a year by the City Arborist during the 3-year period. Energy and Mineral Resources Summary: All gas and electric services are in place for service to the homes on the surrounding lots, with capacity to handle the addition of one single-family residence proposed with the current application. The incremental increase to the use of energy is insignificant because the new residence will comply with Title 24 requirements. Hazards Summary: This project has been designed to comply with all applicable zoning regulations. By its residential nature, this project will not be releasing any hazardous materials into the environment and will not interfere with any emergency response or evacuation plans the City of Burlingame may need to implement. There are no known health hazards on the site. Compliance with the California Building and Fire Code requirements as amended by the City of Burlingame will ensure that people in the new structure are not exposed to health hazards or potential health hazards. NPDES (BMP's) are required to ensure that runoff from the site does not contribute to pollution of adjacent waterways. (See mitigations under Geologic Summary) Noise Summary: The site has been undeveloped and vacant for many years. With the development of a single family dwelling there will be increase noise in the area resulting for habitation of another family in this area. The noise will be general residential noise such as vehicles coming to and from the house, sounds from the residents when using the backyard and proposed swimming pool, noises from putting out garbage cans. The new structure 17 Initial Study Summary 2838 Adeline Drive will be compliant with current construction standards, including increased insulation, which also provides for noise attenuation. The construction of the foundation will be a pier and grade beam design, and will not require the driving of piles. However, due to the depth required for the piers, and the large amount of drilling is required for this project. The hours for drilling shall be limited to Monday through Saturday from 8:00 a.m. to 4:00 p.m., with no drilling on Sundays or Holidays. The remainder of the construction must abide by the construction hours established in the municipal code, which limits construction hours to 7:00 a.m. to 7:00 p.m. Monday through Friday and 9:00 a.m. to 6:00 p.m. on Saturdays and 10:00 a.m. to 6:00 p.m. on Sundays and holidays. Mitigation: That drilling of piers shall be limited to Monday through Saturday 8:00 a.m. to 4:00 p.m., with no drilling on Sundays or Holidays. All other construction shall be done in accordance with the California Building Code requirements as amended by the City of Burlingame, and limits to hours of construction imposed by the City of Burlingame Municipal Code, 7:00 a.m. and 7:00 p.m. on weekdays, 9:00 a.m. and 6:00 p.m. on Saturdays and 10:00 a.m. to 6:00 p.m. on Sundays and holidays. Public Services Summary: The subject property is a vacant lot that is located within the City of Burlingame jurisdiction. However, all of the surrounding properties are within unincorporated San Mateo County. There is an agreement with San Mateo County that the City of Burlingame will respond to all police and fire calls in unincorporated areas of San Mateo County in the Burlingame Hills areas. Burlingame Fire Station 35 is located at 2832 Hillside Drive, just a few blocks away from the subject property and would be the first to respond to emergencies at this site with an excellent response time. The subject property is currently vacant with no vehicular access. The lot slopes steeply from Adeline Drive for approximately the first third of the lot until it levels off to the area where the single family dwelling is proposed to be built. Due to the 20-22% slope on this lot, the driveway proposed to access the house will meander and will not accommodate the turning radius for a fire truck. The City Fire Marshal is requiring a paved throat at the top of the driveway that will accommodate a single fire engine. The applicant is proposing to have a 20' wide by 40' deep paved turnout at the top of the driveway that will allow parking for a fire truck on -site, without blocking circulation on Adeline Drive. The Fire Marshal has also required installation of stairs to emergency personnel direct access down the slope from Adeline Drive to the house. The plans also include a staircase from the turnout down to the lower driveway to allow direct access to the structure for emergency response personnel. The Fire Marshal has requested that this staircase be lighted at tall times for safe passage. Mitigation: That the applicant is shall construct a minimum paved turnout of 20' wide by 40' deep at the top of the driveway to provide parking for a fire truck on -site. That the applicant shall construct a staircase to code standards from the turnout at the top of the driveway to the lower driveway to allow direct pedestrian access to the structure for emergency response personnel. • That the staircase from the turnout at the driveway entrance to the lower driveway shall be lighted from dusk to dawn daily for safe passage. 18 Initial Study Summary 2838 Adeline Drive Utilities and Service Systems Summary: The subject property is vacant and there are no utilities on -site. There is an existing 8 inch sewer on Adeline Drive that serves the existing residences on the block. This line has the capacity to accommodate the new single family dwelling. The applicant will be required have a sewer pump to pump waste water up to the existing sewer main on Adeline Drive. To prevent flooding a backflow prevention device is required to be installed as per Ordinance Number 1710, effective June 18, 2003. The site is sloped steeply from the front to the rear away from the street. Storm drainage is normally required to be drained to the street frontage, however in this case that is not an appropriate solution. Storm drainage shall be designed to flow to the rear of the subject property where there is a drainage channel that flows to Mills Creek, which is located approximately 600 feet north of the subject property. Because of this arrangement NPDES and STOPPP compliance is very important. (See Water Summary section). The current solid waste service provider is BFI, which sends solid waste collected in Burlingame to Ox Mountain Landfill. Construction activities would generate waste during the construction phase. The general contractor will be required to recycle and to reduce the waste stream by transporting the construction waste separately. Solid waste generated during operation of the project would be typical for residential use, and would not be considered substantial. The City of Burlingame has recently adopted an ordinance requiring recycling of construction waste and demolition debris. The ordinance requires that 60 percent of the total waste tonnage generated from project construction shall be diverted from the waste stream. The applicant is required to complete a Recycling and Waste Reduction Form to be reviewed and approved by the Chief Building Official. It is required that records shall be kept and submitted to the City prior to the final inspection of the project. Mitigation: • That the contractor shall submit the "Recycling and Waste Reduction" form to the building department to be approved by the Chief Building Official that demonstrates how that 60 percent of the total waste tonnage generated from proj ect construction shall be diverted from the waste stream and the property owner shall be responsible for the implementation of this plan. • All runoff created during construction and future discharge from the site will be required to meet National Pollution Discharge Elimination System (NPDES) standards. Aesthetics Summary: The site is currently vacant, so the proposed house will have a visual impact on the existing views. The project is subject to residential design review approval by the Planning Commission. The proposed house will be cover 16.3% of the lot and will be 7,797 SF in area. The height as measured from adjacent grade, will be 25'6" and will be setback 63' from the street and —8.61' below the average top of curb. The exterior material will be cedar shingle siding, with a sandstone water table, and a composition roof. The attached garage will have stucco exterior. The windows will have divided lights with wood trim. Exterior lighting provided on the lot will be required to conform to the City's Illumination Ordinance (1477), which requires all illumination to be directed onto the site. Just beyond the rear property line, the Sister's of Mercy have a pedestrian trail on their property which they allow the public to use. During environmental scoping for this project the Planning Commission requested that the applicant look at the view impact of this project, particularly the rear elevations, from the trail. The applicant 19 Initial Study Summary 2838 Adeline Drive has submitted the attached digital images showing the proposed structure from three different vantage points, along with the flowing summary: Prepared by: Doug Johnson of Fat Box Location A The existing photo is taken from the neighboring property. The oaks to remain area shaded by the existing eucalyptus trees. The oaks will develop more fully when the eucalyptus are removed. The oak shown to the left at the initial planting will remain. The tree to the right is a new olive tree located inside the driveway turn. It has a moderate growth rate and an average height of approximately 20 feet. All ground covering is new. After 5 years the oak tree and the olive tree should be more full and the ground covers should fill in. Location B The existing photo provided is taken from the ground level. The digital images are from a point further above the ground level to obtain a better view. The existing photo shows some of the eucalyptus trees to be removed. These trees will be in a flat area of the driveway at the lower garage. The initial planting shows several of the Carolina Cherry Laurels to be planted at the property line fence. After 5 years, these trees should fill in as an effective screen as they have a fast growth rate and an average height of approximately 20 feet. Location C The existing photo was taken from the tail on the property owned by the Sisters of Mercy. The eucalyptus trees shown will be removed. Some trees in the foreground are on the neighboring property and will remain. At the initial planting, the new wall will be built with a chain link fence on top. The house will be visible over/through the Waxleaf Privet. However, after approximately 5 years, the newly planted Waxleaf Privet should block most of the view form the tail as this shrub grows at a fast rate of approximately 12 feet tall. In summary, with the proposed building placement and landscape plan, views from surrounding properties will be minimally impacted. The views from Adeline Drive, from the neighboring property and from the Sisters of Mercy trail at the rear will be filled vegetation from growth from the new plantings. Although the most obvious visual change will be from Adeline Drive where additional paving will be evident with the construction of the driveway. The neighborhood is composed of mostly two-story dwellings. The subject property will be consistent with the development in this area. Mitigation: That this project shall comply with Ordinance No. 1477, Exterior Illumination Ordinance. That the applicant shall provided landscaping on the site as shown on the plans approved by the Planning Commission. All shall be drip irrigated and installed prior to scheduling the final building inspection. That the project shall obtain Planning Commission design review approval before any tree removal, grading or construction takes place on the site. Cultural Resources Summary: Based on other construction activity in the area, it is unlikely that any historical relics will be encountered during construction. Should any archeological or historic, cultural, or ethnic resources be discovered during construction, work will be halted until they are fully investigated. 20 Initial Study Summary Mitigation: 2838 Adeline Drive • That should any cultural resources be discovered during construction, all work shall be halted until they are fully investigated by a professional accepted as qualified by the City Planner and the recommendations of the expert have been executed to the satisfaction of the City. Recreation Summary: The proposed project does not replace or destroy any existing recreational facilities, nor does it displace any proposed or planned recreational opportunities for the City of Burlingame. The site involved in this project is not presently zoned or used for recreational uses. The applicant has no intention of accessing the subject property from Sisters of Mercy trail located at the rear. Mitigation: • That if the applicant finds it necessary to access the subject property from the Sisters of Mercy trail, the applicant shall be responsible for repairing any damage to the trail. SUMMARY OF MITIGATION MEASURES: 1. That there shall be no pilling driving as part of this project. 2.

Please refer to the location indicated on the digital image to the corresponding location on the Landscape Plan. Refer to the Plant List provided for the sizes and growth rate of the individual plants. Location A The existing photo is taken from the neighboring property. The oaks to remain are shaded by the exisitng eucalyptus trees. The oaks will develop more fully when the eucalyptus are removed. The oak shown to the left at the initial planting will remain. The tree to the right is a new olive tree located inside the driveway turn. It has a moderate growth rate and an average height of approx. 20 ft. All ground covering is new. After 5 years the oak tree and the olive tree should be more full and the ground cover should fill in. Location B The existing photo provided is taken from the ground level. The digital images are from a point further above the ground level to obtain a better view. The existing photo shows some of the eucalyptus trees to be removed. These trees will be in a flat area of the driveway at the lower garage. The initial planting shows several of the Carolina Cherry Laurels to be planted on the property line fence. After 5 years, these trees should fill in as an effective screen as they have a fast growth rate and an average height of approx. 20 ft. Location C The existing photo was taken from the trail on the property owned by the Sisters of Mercy. The eucalyptus trees shown will be removed. Some trees in the foreground are on the neighboring property and will remain. At the initial planting, the new wall will be built with a chain link fence on top. The house will be visible over/through the Waxleaf Privet. However, after approx. 5 years, the newly planted Waxleaf Privet should block most of the view from the trail as this shrub grows at a fast rate to approx. 12 ft tall.
