Applicant/Architect: Dale Meyer, AIA, Dale Meyer Associates APNs: 029-121-040 & 029-121-050 Property Owner: Litke Properties, Dennis F. & Michele J. Trimble Lot Area: 24, 637 SF (0.56 acres) General Plan: High density residential use (50+ DU/AC) Zoning: R-4 Adjacent Development: Multi -family residential CEQA Statue: Refer to attached Mitigated Negative Declaration No. 537-P and Addendum Current Use: Multi -family residential dwelling units, two separate lots with a total of 18-units in five structures Proposed Use: 20-unit residential condominium building Allowable Use: Multiple family, duplex and single family dwellings Summary: On November 28, 2005, the Planning Commission approved an application for mitigated negative declaration, condominium permit and special permit for front setback landscaping for a new, four-story, 17-unit condominium building at 1441-1445 Bellevue Avenue, zoned R-4. The applicant is now proposing an amendment to the approved application to reconfigure the floor plan of the building so that it contains twenty units instead of the 17 units approved. With the original project, unit sizes ranged from 806 SF to 3925 SF, with nine of the units exceeding 2000 SF in size. With the revised project, the units range from 780 SF to 2384 SF, and four units exceeding 2000 SF. The building footprint is essentially the same as with the approved application. On November 13, 2006, the Planning Commission reviewed the original request for changes to the approvedproj ect to increase the number of units from 17 to 20 and revise the facade. The Commission voted to continue the hearing on this item to allow the applicant time to make requested changes to the design of the building facade. The Commission directed that the item be brought back on the consent calendar when the following changes had been made. • Provide a mansard roof around the entire building, roofed with the same dark real slate shown in the original proposal; • the stone quoins can be changed to stucco quoins throughout; • the project shall contain 20 dwelling units of the smaller sizes proposed in the second submittal; • the window pattern and balconies should be revised to match the pattern in the second proposal; • all other stone surfaces, except the quoins, should be kept especially around the entry and window trim as shown on the original; and • the fluting around the windows (gull wing) can be done in stucco. The applicant has submitted revised plans and a letter of explanation date stamped December 20, 2006 in response to the Commission's comments. The applicant notes the following changes: • The mansard roof of dark real slate around the perimeter was put back into the design; • Stucco quoins were used throughout, and quoins were added at corners where space allowed; Addendum to Mitigated Negative Declaration and amendment to Condominium Permit and Special Permit for Front Setback Landscaping 1441 & 1445 Bellevue Avenue • Revised project contains 20 dwelling units, minor changes were made to Unit 20 in order to accommodate the mansard roof; • The window pattern proposed with the previous submittal were retained. • Window and door trims, keystones, balusters and railing on rear fourth floor deck, medallions, front entry and pilasters and building trim will be cast stone as noted on the revised plans; and • Quoins, fluting around windows (gull wing), pilasters not at entry will be stucco as noted on the revised plans. Project Description: The applicant, Dale Meyer Associates, is proposing to demolish five structures containing a total of 18 dwelling units and build a new, four-story, 20-unit condominium building with two levels of below -grade parking at 1441-1445 Bellevue Avenue, zoned R-4. The project requires the following planning approvals: • Addendum to Mitigated Negative Declaration, a determination based on the revised project that with mitigation measures there are no significant environmental effects as a result of this project; • Condominium permit for a new, four-story, 20-unit residential condominium project (C.S. 26.30.020); • Special permit for front setback landscaping with a circular driveway (47 % (1300 SF) front landscaping proposed where 50% (1383 SF) is required (CS 26.30.070 e, 1)). If a circular driveway is provided a special permit may be requested to reduce the required front setback landscaping to 45% (1245 SF); and • Tentative condominium map and tentative and final parcel map for lot combination (see Public Works Engineering Staff Report). The two existing parcels will be merged to create a single 24,637 SF lot (0.56 acres). The project requires a condominium permit and a tentative parcel map to merge the two lots and create the condominium parcels. Because two affordable units are proposed, the applicant is using the incentive for height which allows the building height of 45'-8". The applicant is also requesting a special permit for front setback landscaping with a circular driveway to allow 47% (1300 SF) front landscaping proposed where 50% (13 83 SF) is required (CS 26.30..070 e,1). If a circular driveway is provided a special permit may be requested to reduce the required front setback landscaping to 45% (1245 SF). The project as amended requires a total of 44 parking spaces (40 spaces for the 20 units, 3 guest spaces and one delivery space), and a total of 45 parking spaces are proposed. The original project also proposed 45 parking spaces; and there are no changes proposed to the two -level parking garage. A semicircular driveway served by two curb cuts provides access/egress from the site on Bellevue Avenue and provides an on -site parking area for deliveries. There is 5,222 SF of common open space proposed at the rear site, where 2,000 SF is required. The common usable open space is located at the rear of the property on the other side of the bridge and includes the creek. The 75 SF per unit of private open space required is met, with each unit exceeding this requirement with private open space ranging from 75 SF to 440 SF. Inclusionary Zoning: The original project was submitted prior to the adoption of the Inclusionary Zoning regulations which require that affordable units be included with any residential projects with 4 or more units. With inclusionary zoning, the revised project with 20 units proposed requires two affordable units, one unit for every 10 dwelling units with fractions rounded up. Although not required, the original proposal included two affordable units (Unit 4,826 SF & Unit 5, 806 SF). The revised project also includes two affordable units (Unit 4, 780 SF & Unit 5, 818 SF) Since the applicant is providing two affordable units, as required under the Inclusionary Zoning regulations, the project is eligible for up to two of three incentives offered. The applicant has chosen to use the incentive for a building height up to 46' (building height of 45'-8" proposed) without a conditional use pemut and the incentive that allows up to 50% of the required parking spaces to be compact (12 compact spaces (26.6%) proposed). -2- Addendum to Mitigated Negative Declaration and amendment to Condominium Permit and Special Permit for Front Setback Landscaping 1441 & 1445 Bellevue Avenue Addendum to Mitigated Negative Declaration: A mitigated Negative Declaration was prepared for the original project, and was approved by the Planning Commission on November 28, 2005, along with the project approval. An addendum has been prepared for the revised project which analyzes the proposed changes to the project (see attached addendum dated October 17, 2006). Based on this analysis, and on the analysis contained in the Mitigated Negative Declaration for the project, it has been determined particularly since the footprint and envelope of the project stay the same, that the revised project falls within the scope of the original mitigated negative declaration. The conditions of approval from the original project which represent the mitigation measures for the Mitigated Negative Declaration will be incorporated into the conditions of approval for the revised project (refer to attached Mitigated Negative Declaration No. 537-P).

Staff Comments: See attached. Criteria for Permitting a Residential Condominium: The following condominium standards shall apply to all land and structures proposed as a part of a condominium project and shall be evaluated and processed pursuant to the procedural requirements set forth for conditional use permits in title 25 of this code. No condominium project or portion thereof shall be approved or conditionally approved in whole or in part unless the planning commission, or city council upon appeal or review, has reviewed the following on the basis of their effect on: (a) Sound community planning; the economic, ecological, social and aesthetic qualities of the community; and on public health, safety and general welfare; (b) The overall impact on schools, parks, utilities, neighborhoods, streets, traffic, parking and other community facilities and resources; and (c) Conformity with the general plan and density permitted by zoning regulations. Findings for Residential Condominium: Based on the findings stated in the attached minutes of the Planning Commission's November 13, 2006 regular action meeting, and that the revised plans submitted address the Planning Commission's comments regarding the design of the proposal and the revised project contains 20 units rather than the 17 units provided in the original approval, which increases the housing stock in an area which is adjacent to downtown and to transit, the project is found to be compatible with the residential condominium criteria. Findings for a Special Permit: In order to grant a special permit for front setback landscaping, the Planning Commission must find that the following conditions exist on the property (Code Section 25.51.020 a-d): (a) The blend of mass, scale and dominant structural characteristics of the new construction or addition are consistent with the existing structure's design and with the existing street and neighborhood; (b) the variety of roof line, facade, exterior finish materials and elevations of the proposed new structure or addition are consistent with the existing structure, street and neighborhood; (c) the proposed project is consistent with the residential design guidelines adopted by the city; and (d) removal of any trees located within the footprint of any new structure or addition is necessary and is consistent with the city's reforestation requirements, and the mitigation for the removal that is proposed is -4- Addendum to Mitigated Negative Declaration and amendment to Condominium Permit and Special Permit for Front Setback Landscaping 1441 & 1445 Bellevue Avenue Special Permit Findings: Based on the fact that the applicant has provided a circular driveway which accommodates access for delivery vehicles and adequate on -site landscaping is provided throughout the site, it is found that the required special permit findings can be made.

AMENDMENT TO TENTATIVE CONDOMINIUM MAP AND TENTATIVE AND FINAL PARCEL MAP FOR LOT COMBINATION PROJECT ENGINEER: VICTOR VOONG Reference staff report October 13, 2006, with attachments. CP Monroe presented the report, reviewed criteria and staff comments. One hundred -two conditions were suggested for consideration which include the mitigation monitoring plan. Commissioner asked if this project is denied, does the original approval stand. CA responded yes. Commissioner asked if the changes to the project were considered as minor in the context of the Mitigated Negative Declaration. CP responded yes, the addition of three dwelling units and the traffic impacts are minor, parking is provided on the site and the foot print of the building is essentially the same, no change is proposed to the common open space or site landscaping, each unit is provided with private open space, arranged in a more uniform pattern. There were no further questions from the Commission. Chair Brownrigg opened the public hearing. Dale Meyer, architect, 857 Burlway Road, represented the project. He described briefly the changes proposed to the project noting that there is a slight increase in floor area on the forth floor because of the removal of the mansard roof on the rear half of the building; lot coverage is reduced slightly; he noted that the reason for the changes to the number ofunits, size of units and building are based on the changes in the residential market since they did their original market study before applying for the original project. Noted that the rear fagade can be seen from the common open space, feel that there is sufficient articulation in the building to make up for the loss of detail on the rear of the building, no changes are proposed to the common open space and the trees and creek provide a screen to the rear of the building and so changes to the building would not affect use of the common open space; when changed the number of dwelling units looked at the entire fagade , decided to break up the long side walls by removing the mansard roof so the side would look like two elements; proposed change in stone trim to reduce the number of penetrations through the stucco and reduce the maintenance costs for future homeowners association. Commissioners asked: liked the continuous mansard roof and the way the building looked before, can you do the same exterior with a new interior arrangement of 20 units? Architect noted most of the addition units are on the third and fourth floors because gained floor space when removed the mansard roof, putting the mansard back on would reduce at least two of the forth floor units (numbers 18 and 20). Commissioner noted that removal of the mansard roof appears to add about 500SF. Commissioner expressed concern that some people like smaller units but do not think that these will be any more affordable, but the quality of the exterior of the building has been reduced, how is this better for the community? Architect commented that from the last review heard guiding direction to increase the number of units and reduce the size, some of the other items such as removal of stone quoins look at making the building more cost effective, need to balance the cost of construction with the sale price of the units. Commissioner noted that additional dwelling units are good for the community; how did you address the water proofing of the two stories below grade parking garage, is there funding to build the necessary retaining wall and keep it from collapsing? Architect noted worked with engineer on method of water proofing basement area, also will use zipax which is a material used to water proof water storage tanks, have retained a water proofing consultant. Commissioner noted 0 City of Burlingame Planning Commission Unapproved Minutes November 13, 2006 originally wanted driveway relocated to the right side of the lot to give neighbors at 1435 Bellevue more separation from the impact of this project, the mansard roof provided some reduction to the impact, now want to remove half of that, units 18 and 20 most affected have big closets and bathrooms which can be adjusted to accommodate the addition of the mansard roof, would suggest that put 20 units in the original design or build original proposal. Architect noted could put 20 units in the original design with some exterior adjustments for windows and balconies. Commissioner noted hate to see the quality of this initial design spoiled, was not on the commission at the time of the action on the original, but would support that project. Commissioner noted would support changing the quoins from stone to stucco, think there is little difference in appearance and a big difference in cost, agree what like is the mansard roof with darker colored real slate effectively hides the fourth floor from the neighbors. There were no further comments from the floor. The public hearing was closed. Commissioners comments: As understand it, if approve this revision the applicant can build either project? CA noted until the approval for the original expires. More smaller units is an advantage to the city, not see mansard as critical, changes on the elevations are fine, when it is built the details on either set ofplans would fit in; agree about adding more units, but design should be more in keeping with original; think that the window and balcony arrangement is better with the second proposal but the mansard roof should extent around the entire building. Chair Brownrigg made motion to place this item on the consent calendar when the applicant has addressed the following: ■ a mansard roof around the entire building, roofed with the same dark real slate shown in the original proposal; ■ the stone quoins can be changed to stucco quoins throughout; ■ the project contain 20 dwelling units of the smaller sizes proposed in the second submittal; ■ the window pattern and balconies should be revised to match the pattern in the second proposal; ■ all other stone surfaces, except the quoins, should be kept especially around the entry and window trim as shown on the original; and ■ the fluting around the windows (gull wing)can be done in stucco. The motion was seconded by C. Deal. Comment on the motion: commission wants to be careful not to design the building for the architect and over correct for the changes; to have the whole building in stucco is too much, stone accents have an impact; willing to do away with the stone veneer on the first floor. Chair Brownrigg called for a voice vote on the motion to continue this item to a time when revised plans have been submitted to the Planning Department, have been plan checked and there is space on an agenda. The motion passed on a 7-0 voice vote. The continuation includes the Tentative Map. This action is not appealable.

This letter is in response to the Planning Commission study session comments on October 23, 2006 regarding the above referenced project: Our clients observed a change in the market place, as we were getting ready to start the construction documents. They decided to wait and see what was happening in the economy, with the interest rates, world politics, and the market direction. Because of this information, the clients determined that a reduction in the size of the larger units was desirable. This allowed us to increase the number of smaller units in the project as discussed with the Planning Commission during a previous hearing. The changes to the floor plans allowed us to also take another look at the elevations. Review of historical French buildings produced examples where the most prominent facades (street elevations) are the most elaborate. We used this idea to create additional interest to the side elevations by breaking the length into two visual elements. 2. The view from the common open space was considered. We felt it worked very well because of the considerable amount of articulation in the fagade, including various height changes, the large redwood tree, and the creek. The clients requested that we look for some alternate means of construction in order to reduce the construction time. Some of the detailing was revised to accommodate that request.

CITY OF BURLINGAME SPECIAL PERMIT APPLICATION for circular driveway & 45% front landscaping 1441-1445 BELLEVUE AVENUE f AUG ® 12006 CITY OF BURLINGAME PLANNING DEPT. 1. The proposed structure will be a beneficial addition to the surrounding neighborhood by exhibiting aesthetically pleasing architectural details and forms executed by good construction practices. A circle driveway will be provided that will remove drop-off and delivery congestion from the street. The circle driveway will be screened by landscaping fronting the street and also by the existing street trees that will remain. The neighboring property on the right side of the proposed project is a three-story condominium building. The neighboring property on the left side of the proposed project is a three and a half story condominium project. The proposed project is a four-story condominium building with the fourth floor within a mansard roof that slopes back from the face of the building, thereby creating a structure that is not as massive. In addition, the rear one-third of the property across the creek will not be developed. Instead it will be tiled open space with pergolas and a fountain and will be landscaped beautifully to create a lush, cool park like setting next to the creek. 2. The proposed project will integrate well and improve the aesthetics of the surrounding neighborhood with the use of classic French architectural detail. The project was designed with classical elements found in this type of architecture. Several structures in this neighborhood have elements of classical architecture in their detailing and therefore our proposed structure will integrate well into this neighborhood. The character of the proposed project will have a positive influence in the neighborhood by setting an example of classic architectural style with the use of clean lines, symmetry and repetition. 3. The proposed project is designed to be compatible with the surrounding neighborhood by using traditional detailing that will continue to be elegant and timeless throughout the years. Parking and garage patterns was taken into consideration by designing an efficient garage with ample spaces to accommodate each unit as well as visitor spaces to reduce on -street parking use and traffic congestion. A circle driveway is designed into the project to help ease traffic congestion by providing an area off-street where drop-offs and deliveries can occur. The proposed building will integrate well with structures on adjacent properties by it's location, architectural detailing and landscaping. The proposed building is located past the average block front setback and set in on the sides by more than is required by the City's zoning code. The proposed building's architectural style is French using classic French architectural details. New landscaping around the building will screen and buffer the proposed building from adjacent properties. 4. 5 trees on the proposed circular driveway will be removed. 14 - 24" box trees are proposed to replace the existing trees being removed.

CP Monroe presented the report, reviewed criteria and staff comments. Ninety-four conditions which include the mitigations from the Mitigated Negative Declaration were suggested for consideration. There were no questions of staff. Chair Auran opened the public hearing. Dale Meyer, architect, represented the project; Michael Callan, landscape architect for the project, 1400 Rollins Road; Abraham Landis, 1547 Bellevue Avenue; Mark Engleman, 1435 Bellevue, # 105, Redwood Crest Homeowners Association, spoke. Applicant summarized the revisions made to the plans in response to the Commission's comments at study; Commissioners noted regarding revised plans that there is no closet in the bedroom in unit 5; that because of the orientation of the sun and the project, the depth of the fourth floor deck on the rear of the building will have a big impact on the light access to the building next door; clarified that what looks like balconies on the front of the building are actually decorative wrought iron grills; concern about the survival of the redwood tree at the rear, commissioner noted that with removal of the Cypress growing next to the redwood, the redwood will fill out; for safety, outdoor fire place should not be wood burning nor should a shed for storing wood be located in the public open space, gas with timed turn-off valves for grill and fireplace would be safer and more practical; feel that the structure is not placed correctly on the site, too close to the building on the right, driveway should be reversed and building moved to the left, this is so serious cannot support the project; common open space has a real sense of space but needs a sink with running water, a toilet, and the bridge needs to remain central to the open space and building but also should not be built against the redwood tree, be sure foundation ofbridge protects redwood roots; two story below grade parking garage located next to a creek raises serious questions about sump pumps running 24 hours a day, where the water is pumping to so creek will not be contaminated, not want to see fossil pillows used to clean water; CP noted that the mitigations from the Mitigated Negative Declaration address these drainage and water quality issues, including various sump pumps, back up generators and drainage receptors, and the mitigations are implemented as conditions of approval; important that the sump pumps and emergency generators are sound baffled so that they cannot be heard by the neighbors or by the residents of the proj ect; on the balconies on the southwest elevation the balconies are cantilevered from the cornice and look awkward, they should be moved to align with the balconies below and corbels added below the uppermost balconies to visually attach them to the structure; the window pattern still seems monotonous, could be more interesting; the plans show the roof to be real slate, would not like to have a revision from this material later; SE Bell noted that it is important that the excavation for the garage and the parking is built in one season because of the creek, otherwise the hole should be properly shored to insure that it will not fail because of the proximity of the creek and adjacent development, the project should be bonded to insure this; there is limited opportunity to install big trees, would be nice to replace the Liquid Ambers on the street with a bigger, evergreen species, but that is up to the City; on the right side elevation should install "forest scale" tree to establish proper screening, Podocarpus on the left side should also be replaced with two "forest scale" evergreen trees, these would hide the limited space between buildings; Pittosporum along the right side property line should not be trimmed in order to provide the highest screen possible for residents in the adjacent building; check with Department of Fish and Game about what should be planted along the creek bank to stabilize it, at least filter M City of Burlingame Planning Commission Minutes November 28, 2005 fabric should be put on the bank and material planted through it, concerned about erosion during and after construction. Continued public comment: part of this building faces his condominium, will be all that is visible from all windows, now sees greenery; will reduce the value of his condominium; studies show this kind of change can have an effect on the mental health of older people; bought condominium 10 years ago, three story building, not expect visual impact of four story building next door. Redwood Crest Condominium would like to work with the developer on selecting the fence between the two properties, would like to leave existing vegetation at the front and start fence back some; concerned about the crooked telephone pole in the right-of-way at the front, would like it installed so it is up right now and in the future would like the service placed underground. Applicant noted they would work with the homeowners association on the selection of the fence between the two properties.

INTRODUCTION This Mitigated Negative Declaration addendum has been prepared in compliance with Section 15164 of the implementing guidelines of the California Environmental Quality Act (CEQA Guidelines), which permits a lead agency (in this case, the City of Burlingame) to prepare an addendum to the previously prepared mitigated negative declaration if some changes or additions to that mitigated negative declaration are necessary, but none of the changes are sufficiently substantial to warrant preparation of a new (or a subsequent mitigated negative declaration pursuant to Section 15162 of the CEQA Guidelines. As approved by CEQA Guidelines Section 15164, this addendum maybe included in, or attached to the Mitigated Negative Declaration, but it need not be circulated for public review. On November 28, 2006, the Planning Commission approved a Mitigated Negative Declaration and approved a condominium permit and special permit for front setback landscaping for the proposed four-story, 17-unit residential condominium. The applicant has now submitted an amended proposal with the same building footprint and parking layout. The applicant proposes to reconfigure the floor plan to provide 20 smaller units instead of the 17 units approved, and to make changes to the exterior fagade of the building. The addendum for the Mitigated Negative Declaration has been prepared for the revised project now proposed atl441-1445 Bellevue Avenue, Burlingame. The revised project differs in the following key respects: FLOOR PLANS • Reconfigured the floor plans on the second and third floors to increase the number of units per floor from four to five; and reconfigured the fourth floor plan to increase the number of units from three to four (total of 3 additional units); • With the original project, there were two 1-bedroom units, seven 2-bedroom units and eight 3-bedroom units proposed. The revised project includes two 1-bedroom units, seventeen 2-bedroom units and one 3-bedroom units proposed. The total number of bedrooms was reduced from 40 bedrooms to 39 bedrooms); and • The number of required on -site parking spaces increased from 41 to 44 (40 parking spaces required for the 20 units, plus three guest parking spaces and one delivery space). However, there in no change in the number of parking spaces proposed on the site (45 on -site parking spaces). DESIGN CHANGES Front (Northwest) Elevation • Stone quoins at corners and stone veneer around arched windows replaced with stucco quoins and veneer; • Second and third floor windows and/or doors changed from arched to rectangular; and ADDENDUM FOR MITIGATED NEGATIVE DECLARATION 1441-1445 BELLEVUE AVENUE • Metal railing removed from fourth floor windows. RiLyht Side (Southwest) Elevation • Rear half of fourth floor changed from slate mansard style roof to stucco siding with baluster and railing added at roof edge; • Second and third floor windows and/or doors changed form arched to rectangular; • Sizes and locations of windows and doors changed; • Additional balconies added; • Fourth floor balconies now line up with those on the second and third floors; and • Stone quoins removed at rear wall corner. Rear (Southeast) Elevation • Fourth floor changed from slate mansard style roof to stucco siding with baluster and railing added to the roof edge; • Second and third floor windows and/or doors changed form arched to rectangular; • Sizes and locations of windows and doors changed; • Decorative molding removed from arched windows; and • Stone quoins removed at wall corners. Left Side (Northeast) Elevation • Fourth floor changed from slate mansard style roof to stucco siding with baluster and railing added to the roof edge; • Second and third floor windows and/or doors changed form arched to rectangular; • Sizes and locations of windows and doors changed; • Decorative molding removed from arched windows; • Stone quoins removed at rear corner; and • Stone quoins and stone veneer around arched windows replaced with stucco quoins and stucco veneer. There is no change proposed to the building footprint or building height, and the parking layout in the two levels of underground parking remains the same as the approved project. The proposed density of the project would increase from 30.4 units per acre to 35.7 units per acre. The General Plan designates this site and the surrounding area for high density residential use (50+ units per acre). The proposed increase in density still falls below the density allowed in the General Plan. C. IMPACTS TO TRANSPORTATION/TRAFFIC (PARKING SUPPLY) With the revised project, the total number of units would increase from seventeen units to twenty units. However, the number of 3-bedroom units was reduced. With the original proposal there were eight 3-bedroom units, seven 2-bedroom units and two 1-bedroom units, which results in a requirement for 37 parking spaces. The revised project includes one 3-bedroom unit, seventeen two - bedroom units and two 1-bedroom units. This results in a requirement for 40 parking spaces. Both the original and the revised projects require three guest parking spaces and one delivery space. The total parking required increases from 41 spaces to 44 spaces. As with the original proposal, the project proposes to provide 45 on -site parking spaces (31 standard, 12 compact and 2 disabled accessible), where the zoning code requires 44 parking spaces. -2- ADDENDUM FOR MITIGATED NEGATIVE DECLARATION 1441-1445 BELLEVUE AVENUE No changes are proposed to the on -site circulation. The original analysis of the on -site circulation prepared by Hexagon Transportation Consultants dated January 30, 2004 concluded that the parking layout does not create any hazardous conditions. With inclusionary zoning, the applicant may use up to two of three incentives offered including increasing the building height up to 46'-0", reducing the common open space byup to 50% or 200 SF (whichever is greater), or increasing the number of compact parking stalls (50% of required parking may be compact if more than 10 parking spaces are required). The applicant has chosen to use the compact parking incentive for the project (12 of the 44 required parking spaces are proposed to be compact, where 22 compact spaces are allowed with this incentive). A 24'-0" clear back-up aisle is provided for all parking spaces. Parking for a delivery vehicle is provided in the proposed semi- circular driveway. The applicant submitted a traffic and parking study prepared by Hexagon Transportation Consultants dated January 30, 2004. The study looks at the potential traffic impacts from the change in the number of dwelling units on the site (18 existing units, 17 units with the original proposal) as well as an analysis of the on -site and on street parking and circulation. Based on the analysis in the traffic study, the project as originally proposed resulted in a net decrease in trip generation, both because the number of units was to decrease, and because the trip generation rate for condominium units (owner occupied) is less than for apartment units (rental). With the proposed increase in units from 17 to 20 units, the trip generation would be the same as under existing conditions with 18 apartment units. Therefore, the project will not create a substantial increase in the traffic generation in the area. All arterial, collector, and local roadway systems in the City have the capacity to accommodate the incremental traffic or trip generation produced by the proposed increase of two dwelling units for this project compared to existing conditions. The proposed condominium building meets the on -site parking requirements established in the Zoning Code and in the most recent Condominium Ordinance. D. IMPACTS TO AESTHETICS The footprint and the envelope of the proposed four-story condominium building have not changed with the revised project, and the overall style of the building has not changed. The shadow simulation prepared for the original project would still apply to the project as revised. There are several revisions which have been made to the fagade of the building. Window locations and shapes have been revised, and the style at the rear of the building has been altered, with the mansard roof replaced with stucco siding with a baluster and railing added at the roof edge. In addition, there have been changes to building materials, the proposed stone quoins and trim at the corners and on the front and left side elevation have been replaces with stucco quoins and trim. The Mitigated Negative Declaration and Addendum for the proposal identifies potential impacts in the areas of transportation and circulation, noise and aesthetics. All of these potential impacts were determined to be reduced to less than significant with the implementation of the mitigation measures identified in the initial study. With the proposed changes in the project, no additional impacts are anticipated, and the identified mitigation measures are still applicable to the revised project. -3- CITY OF BURLINGAME NEGATIVE DECLARATION APR - 4 2005 COUNTY MANAtAER File No. ND-537- P The City of Burlingame by Margaret Monroe on April 4, 2005, completed a review of the proposed project and determined that: (XX) It will not have a significant effect on the environment (XX) No Environmental Impact Report is required. Project Description: The applicant is proposing anew, four-story, 16-unit condominium building with two levels of below -grade parking at 1441-1445 Bellevue Avenue, zoned R-4. The site now consists of two lots which contain a total of 18 apartment units, in five structures. All of the existing structures on -site will be demolished and the two parcels will be merged to create a single 24,637 SF lot (0.56 acres). The project will include four 4-bedroom units, six 3-bedroom units, five 2-bedroom units and one 1-bedroom unit. The project requires a total of 37 parking spaces (34 spaces required based on the number of bedrooms, plus three guest parking spaces). The applicant is proposing 41 on -site parking spaces in the two-story below -grade garage, which is accessed from a driveway along the left side of the property. The project requires a condominium permit and a tentative parcel map to merge the two lots and create the condominium parcels. The applicant is requesting a conditional use permit for building height of 45' 8" where a conditional use permit is required for height over 35'. The applicant is also requesting a variance for 42.7% (1169 SF) front setback landscaping where 60% (1660 SF) is the minimum required. This proj ect was submitted prior to the adoption of the Inclusionary Zoning regulations which require that affordable units be included with any residential projects with 4 or more units. The 16-unit proposal would require two affordable units, one unit for every 10 dwelling units with fractions rounded up. The applicant is proposing that Unit 4, the one -bedroom unit, will be an affordable unit. If the applicant were to provide two affordable units, as required under the Inclusionary Zoning regulations, then the applicant may have a building height up to 46' without a conditional use permit. However, since there is only one affordable unit where two are required for the incentive to apply in this case, a conditional use permit for building height is still required. A semicircular driveway served by 2 curb cuts provides access to the site from Bellevue Avenue and provides an on -site parking area for deliveries. The project meets all other zoning code and condominium permit requirements. Reasons for Conclusion: This project is in -fill development and is consistent with the General Plan and zoning. The project is a reuse of two lots which are currently developed with multiple -family residential structures. The proposed 16-unit residential condominium building meets all R-4 (multi -family residential) zoning regulations with the exception of a conditional use permit for height and front setback landscaping. variance. Adjacent land uses along Bellevue Avenue, Almer Road, Floribunda Avenue, and El Camino Real will not be adversely affected by this proposal since these lots are primarily developed in multiple family residential Mitigated Negative Declaration 1441-45 Bellevue Avenue page 2 uses. No new transportation methods or corridors will be needed since the site is served with adequate roadway and circulation capacity now and with parking to zoning code on site will not impact on street parking or travel lanes. No new recreational or governmental facilities will need to be extended or created to support the proposed development because the project proposes to reduce the number of residential units on -site by two in an area already developed and fully served with facilities appropriately sized. Referring to the initial study for all other facts supporting findings, it is found that there is no substantial evidence that the project will have a significant effect on the environment.

Description of the Project: The applicant is proposing anew, four-story, 16-unit condominium building with two levels ofbelow- grade parking at 1441-1445 Bellevue Avenue, zoned R-4. The site now consists of two lots which contain a total of 18 apartment units, in five structures. All of the existing structures on -site will be demolished and the two parcels will be merged to create a single 24,637 SF lot (0.56 acres). The project will include 16 dwelling units: four 4-bedroom units, six 3-bedroom units, five 2-bedroom units and one 1-bedroom unit. The project requires a total of 37 parking spaces (34 spaces required based on the number of bedrooms, plus three guest parking spaces). The applicant is proposing 41 on -site parking spaces in the two-story below -grade garage, which is accessed from a driveway along the left side ofthe property. The project requires a condominium permit and a tentative parcel map to merge the two lots and create the condominium parcels. The applicant is requesting a conditional use permit for building height of 45' 8" where a conditional use permit is required for height over 35'. The applicant is also requesting a variance for 42.7% (1169 SF) front setback landscaping where 60% (1660 SF) is the minimum required. This project was submitted prior to the adoption of the Inclusionary Zoning regulations which require that affordable units be included with any residential projects with 4 or more units. The 16-unit proposal would require two affordable units, one unit for every 10 dwelling units with fractions rounded up. The applicant is proposing that Unit 4, the one -bedroom unit, will be an affordable unit. If the applicant were to provide two affordable units, as required under the Inclusionary Zoning regulations, then the applicant would be allowed a building height up to 46' without a conditional use permit. However, since there is only one affordable unit where two are required for the incentive to apply in this case, a conditional use permit for building height is still required. A semicircular driveway served by 2 curb cuts provides access to the site from Bellevue Avenue and provides an on -site parking area for deliveries. The project meets all other zoning code and condominium permit requirements. 9. Surrounding Land Uses and Setting: To the right and left sides of the subject property are residential condominium buildings. The property at the rear of the subject property is a commercial building zoned C-1, subarea B, with office uses including real estate and mortgage brokers. The surrounding area is planned for high density residential uses (51 plus units per acre) and is zoned R-4 (multi -family residential). The proposed residential density is 28 dwelling units per acre and is within the densities allowed for this area in the General Plan. 10. Other public agencies whose approval is required: A permit will be required from the Bay Area Air Quality Management District for demolition of the existing structures. A Streambed Alteration Permit is required by the California Department of Fish and Game because of the proximity of construction adjacent to Ralston Creek as well as the location of the two-story below grade parking garage. Additional permits may also be required from the California Regional Water Quality Control Board as well as the Army Corp of Engineers. 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.

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 notbe 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.

("Cumulatively considerable" means that the incremental effects of a 1 X project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects)? c) Does the project have environmental effects which will cause substantial adverse effects on human beings, either 1 X directly or indirectly? 10 Initial Study Summary 1441-1445 Bellevue Avenue 18.

LAND USE AND PLANNING SUMMARY: The General Plan designates this site for high density residential uses, which allows for the construction of 50 plus units per acre. The R-4 zone permits condominium buildings and requires a condominium permit and a tentative parcel map to merge the two parcels and create the condominium parcels. The 16-unit condominium building will be located on a 0.56 acre site, which results in a density of 28 units per acre, which is within the range established by the high density residential General Plan designation. The project requires a conditional use permit for building height of 45' 8" where a conditional use permit is required for height over 35'. The project also requires a variance for 42.7% (1,169 SF) front setback landscaping where 60% (1,660 SF) is the minimum front setback landscaping required. The Planning Commission may grant a conditional use permit and a variance if findings can be made as required in the zoning code. The project meets all other requirements of the R-4 zoning district. A tentative parcel map to merge the two lots is required to create the developable site. 2. POPULATION AND HOUSING SUMMARY: This site and the surrounding area are planned for high 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 does not convert rental housing to condominiums but is anew construction project that will result in a new condominium building consistent with other such developments in the area. The total number of units on these two combined parcels will be reduced by two from 18 to 16. However the overall number of bedrooms on this site is increasing from 20 bedrooms to 41 bedrooms, therefore allowing a greater total number of people to reside on the site. An analysis of the effect of this project on the housing stock was prepared for the applicant by Cashin Company. This analysis states that within a mile radius of the subject site that there are approximately 1,261 apartment units. The vacancy rate for apartments in Burlingame in mid-2004 was about 10%. Rental values have declined approximately 20% in the last few years. Therefore it is assumed by this analysis that tenants in the building at 1441 and 1445 should not have a hard time finding replacement housing. The report also states that both 1441 and 1445 are economically obsolete buildings with the cost of upgrading the buildings to current code standards being financially infeasible. Both buildings are in need of both structural upgrades and seismic corrections. Both have reached the limit of their lifespan. 3. GEOLOGY SUMMARY: Setting Geoforensics prepared a geotechnical investigation for this project. In addition Bay Area Geotechnical Group performed two studies for the project: geology, soils and seismic setting report and geotechnical consultation —dewatering. The analysis is based on a review of existing literature, geologic, soil and seismic hazard maps, as well as a site reconnaissance and previous Geotechnical Investigation for the site property (GeoForensics Inc., 2002). The information from these sources has been summarized and included in the following geologic analysis. 13 Initial Study Summary 1441-1445 Bellevue Avenue Bay Area Geotechnical Group performed studies a site reconnaissance on February 11, 2004. The site is located within a residential area in the south portion of Burlingame, California. The prominent site features consist of five one- and two-story wood, brick and stucco apartment buildings, with concrete paved parking areas in the south lot (1445 Bellevue Avenue) and asphalt paved parking areas in the north lot (1441 Bellevue Avenue). Ralston Creek bisects both lots, with the portion on 1445 Bellevue contained by concrete retaining walls supporting the two-story apartment building above, and the portion on 1441 Bellevue is an open flow channel with concrete and rock -lined sides and bottom, with landscaped vines and trees along the upper banks. Access to the one -and two-story wood -framed apartment structure across the creek is by a wood footbridge. The footbridge is supported on what appears to be shallow foundations with concrete lining the slope bank along the west portion below the bridge. The greater San Francisco Bay Area is recognized by Geologist and Seismologists as one of the most active seismic regions in the United States. Three major fault zones pass through the Bay Area in a northwest direction and have produced approximately 12 earthquakes per century strong enough to cause structural damage. The faults causing such earthquakes are part of the San Andreas Fault System, amajor rift in the earth's crust that extends for at least 700 miles along the western portion of California. The San Andreas Fault System includes the San Andreas, Hayward, and the Calaveras Fault Zones, as well as other strike -slip faults in the northern Coast Ranges. Geology of the general site area is dominated by alluvium of different ages. Based on a review of the Geologic Map of the Montara Mountain and San Mateo 7'/ 'Quadrangles, San Mateo County, California (USGS Map I-2390), by Earl H. Pampeyan (1994) the site is mapped as Older Alluvium. Pampeyan describes these materials as consisting of "weathered, unconsolidated to moderately consolidated gravel, sand, silt, and clay in various proportions and combinations, chiefly older alluvium fan deposits; locally this includes younger alluvial and colluvial deposits." The active (surface rupture within the last 11,000 years) San Andreas Fault Zone is located approximately 2.5 miles (4 kilometers) west-southwest of the site. In 1999, the U.S. Geological Survey cited a 70 percent probability that a Richter magnitude 6.7 earthquake (Working Group on California Earthquake Probabilities, 1999) would occur on one of the active faults in the San Francisco Bay Region in the following 30 years. Recently, this probability was decreased to 62 percent, as a result ofnew data and new methodologies. A 21 percent probability is still attributed specifically to the potential for a magnitude 6.3 earthquake to occur along the San Andreas fault by the year 2031. No active earthquake fault zone boundary or active fault trace cuts the subj ect property. The nearest earthquake fault zoned as active by the State of California Division of Mines and Geology (CDMG) is the San Andreas Fault zone located approximately 4 kilometers west-southwest of the subject site. The site is relatively level with the west side of the property sloping gently down to the east towards Ralston Creek, which runs north to south across the back one-third of the lot. The east side of the property slopes gently down to the west towards the creek. Surface gradients range from 20:1 to 10:1 (horizontal to vertical, H:V). During the original development of the property, it appears that up to 5 feet of fill was required to create the existing level building pad. The banks of the creek generally form 2:1 slopes varying from 4:1 to 1:1 down from the pads, On the east side of the creek borings drilled for the geotechnical investigation encountered 2.5 feet of sandy clay fill. Below this fill is old topsoil consisting of stiff lean clay with sand to a depth of 6 feet. Below this was loose clayey sand which graded to stiff lean clay to a depth of 12 feet. On the west side of the creek similar soil conditions were encountered in 14 Initial Study Summary 1441-1445 Bellevue Avenue the borings. The borings first penetrated 7 to 7.5 feet of firm to very stiff lean clay material with varying amounts of gravel and sand (topsoil and fill). This material was underlain by native sandy lean clay in a stiff to very stiff condition to depths of 12 to 17 feet. Below 17 feet, either a loose to medium dense sand with clay or clayey sand/sandy lean clay was encountered in the borings. The hazard due to large-scale seismically induced landsliding is relatively low for the site. However, as with any slope, minor sloughing of the steeper creek slopes could occur during earthquake shaking. The proposed improvements should not be affected by any such sloughing, as the building will be supported on foundations embedded below the bottom of the creek. The banks of the creek will have to be maintained to mitigate soil bank erosion. In May 2002, groundwater was encountered at depths of 16.5 and 23.5 feet below ground surface on the north and west limits of the property. The groundwater rose to 9 and 17 feet respectively after one hour. However during periods of heavy rain or in the winter, a higher groundwater table than that encountered during the field exploration may exist. The water in the creek will also saturate the soil immediately adjacent to the creek. Ground shaking occurs when earthquakes occur at some distance from a site. The peak ground acceleration at a site is dependant upon the magnitude of an individual earthquake, the distance from the site, and the type of formation (bedrock, soft soil), among other factors. The current building code design should be followed by the structural engineer to minimize damage due to seismic shaking. The site should be considered to have a Soil Profile Type SD as defined in Table 16-J of the Uniform Building Code(1997). Improvements should be designed to resist shaking from a Seismic Source Type A, located about 2.5 miles (4 kilometers) from the site. Alternately, site -specific accelerations may be used by the structural engineer for the design of the proposed improvements. Soil liquefaction occurs when a loose to medium dense, saturated granular soil (silty sands and sands) undergoes a rapid loss in strength due to an increase in pore pressure generated within the soil mass. This total loss of shear strength is induced by strong ground shaking associated with earthquakes. Based upon the subsurface investigation, the proposed site is underlain by resistant clay rich materials at shallow depths. Therefore, liquefaction is unlikely to affect the subject property. Dynamic densification typically occurs in loose sand deposits located above the ground water level when subjected to strong ground motions associated with large earthquakes. No loose soils are present at shallow depth below the site. Therefore, dynamic densification of the near surface soils is unlikely to affect the subject property. Project Impacts The proposed development will consist of demolition of the existing apartment buildings and the existing wood bridge over the creek, and construction of a single condominium building with an underground parking area. The two -level underground parking area will have an approximate finish floor elevation of 14.0 feet for the lower floor, which will be significantly lower than the creek bottom, which is about 23 feet below grade at the north edge of the site. The portion of the lot to the east of the creek will be developed into an open, common area accessed by a new pedestrian bridge. The existing concrete retaining walls at the southern portion of the creek will remain. The areas of environmental concern that may be associated with implementation of the proposed project include the potential to expose people or structures to substantial adverse effects, including the risk of loss, injury, or death involving: 9 Rupture of a known earthquake fault, as delineated on the most recent Alquist-Priolo Earthquake Fault 15 Initial Study Summary 1441-1445 Bellevue Avenue Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault. Refer to Division of Mines and Geology Special Publication 42. • Strong seismic ground shaking. • Seismic -related ground failure, including liquefaction. • Potential to be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on- or off -site landslide, lateral spreading, subsidence, liquefaction or collapse. • Potential to be located on expansive soil, as defined in Table 18-1-B of the Uniform Building Code (1997), creating substantial risk to life or property. The CEQA Guidelines state that the exposure of people or structures to major geological hazards is considered a significant adverse impact. The potential geologic, soils, and seismic effects of the proposed project can be considered from two points of view: (1) construction impacts; and, (2) geologic hazards to people or structures. The basic criterion applied to the analysis of construction impacts is whether or not construction of the project will create unstable geologic conditions that would last beyond the short-term construction period. The analysis of geological hazards is based on the degree to which the site geology could produce hazards to people or structures from earthquakes, ground settlement, or other geologic hazards, features or events. Although projects can have impacts on the local geologic environment through induced slope instability and soil erosion, most projects do not affect the regional and sub -regional geologic environment. However, projects can be affected by regional, sub -regional, and area wide geologic conditions. Many seismic events, particularly large magnitude earthquakes, are felt regionally and sub -regionally. Injury, damages, and property loss tend to occur along and near linear earthquake fault zones of regional extent and in areas of soil and geologic conditions susceptible to rapid ground motion, settlement, or instability. One such susceptible hazardous condition is the occurrence of steep and potentially unstable slopes. Such conditions are common in the foothills of the coast range, but are not found on this property. The occurrence and extent of significant damage may be localized, as dictated by site -specific geologic conditions. Most seismic experts agree that for planning and project evaluation purposes, a large, damaging earthquake event should be anticipated to occur within the design life of all projects in the San Francisco Bay Area. Regional and local geologic impacts that could significantly impact the project will primarily be damages to the infrastructure (utilities, roads, etc.). Following the discussion of impacts, mitigation measures are presented that address the potentially significant geologic impacts associated with the proposed residential development on the project site. Most of the defined measures require proper engineering design and construction practices, which, if implemented, will reduce potentially significant impacts to an insignificant level. No active faults cross the subj ect property, but nearby faults and regional sources of seismicity could cause strong to violent ground shaking at the subject property. In the event of a major earthquake on a nearby fault or within the San Francisco Bay Region, ground shaking at the project site could be strong to violent. The intensity of the seismically -induced ground shaking would be a direct result of the distance from the epicenter and the magnitude of the earthquake. Damage to the proposed building and streets at the site would likely occur in this event. Seismically induced ground shaking is a potentially significant impact. 16 Initial Study Summary 1441-1445 Bellevue Avenue The seismic impacts from a large magnitude earthquake would be significantly reduced with implementation of the mitigation measures listed in the section below; however, property damage and loss of life could still occur. It is projected that a local earthquake along the San Andreas or Hayward faults will result in moderate to violent ground shaking in the proj ect site area. Moderate ground motions can be expected during earthquakes of lesser magnitude on nearby faults and during larger magnitude earthquakes on more distant faults. Violent ground shaking can be expected to occur during peak magnitude earthquakes on nearby sections of the S an Andreas. Completion of the mitigation measures as described in the section below for the identified seismic hazards will reduce the impact of the seismic hazards on humans. Potentially expansive soils underlie the site. Expansive soils shrink and swell in volume during changes in moisture contents. Changes in moisture occur seasonally or because of irrigation and can cause damage to foundations and pavement sections. The possibility of expansive soils is considered a potentially significant impact. Implementation of the mitigation measures listed in the section below would reduce the impact from expansive soils to less than significant. The proposed project plans call for excavations for the underground parking garage to extend to approximately 20 feet below the existing ground surface. Excavations are proposed to extend to the southern property line adjacent to existing structures on adjacent properties. Excavations could potentially affect structures on adjacent properties located within several feet of the proposed excavations. These effects could include failure of cuts and settlement or failure of foundations on adjacent properties. The potential for unstable excavations is considered a potentially significant impact. Implementation of the mitigation measures listed in the section below will reduce the impact from unstable excavations to a less than significant level.

HYDROLOGY AND WATER SUMMARY: Setting Hydrology and Water Quality Report was prepared for this project by Bay Area Geotechnical Group in November, 2004. At the time of this report, the site consists of two adjacent lots encompassing 24,388 square feet, and containing five multiple family buildings. Ralston Creek crosses the eastern portion of the two lots in a northerly direction, and is straddled by a 2-story multiple family building at the southeast portion of 1145 Bellevue Avenue. The creek below this structure is lined with concrete bags before passing underneath this building where the creek channel is lined with rock -lined concrete retaining walls on both sides. It should be noted that the creek is contained within a 72-inch-diameter culvert where it crosses the lot to the south and upstream of the site, and is predominantly an underground stream through the City of Burlingame. The concrete walls end at the property line to 1441 Bellevue Avenue, where the creek banks are vegetated soil sloping at gradients of approximately 4:1 before dropping off to the creek channel at an approximate gradient of 1:1. Noticeable drainage features now on the site consist of drop inlets at the centers and sides of the parking areas, with most pipes leading to storm drain facilities beneath Bellevue Avenue. One drop inlet at the center of the lot at 1441 Bellevue has two pipes, one draining toward the street and one with a visible trench patch on the asphalt leading to the creek. Closer to the creek on 1445 Bellevue Avenue, the asphalt surface slopes toward the creek, and water flow is drained toward the creek through breaks in the wood curb. It was also noted that south of the footbridge there are two septic boxes. At 1441 Bellevue Avenue, drainage on the concrete surface is accomplished by two small drains at the eastern portion of the parking area. (The drainage most likely leads to the creek, but the consultant was unable to find the outlet pipe.) Drainage features at the site consist of several drop inlets in the asphalt parking areas, with most leading to storm drain collectors in the street. One 6" storm drain pipe apparently leads to Ralston Creek. Based on the water study by Kavanagh Engineering, the 100-year flood level of the creek will have a maximum elevation of approximately 31 to 29 feet above MSL (mean sea level) at the project site, which is below and approximately 10 feet away from the existing wood curb along the west side of the creek. The creek channel is 6 to 7 feet deep. W Initial Study Summary 1441-1445 Bellevue Avenue At the time of the consultants site visit, Ralston Creek had approximately 6 inches of flowing water. It was also noted that the channel bottom contained much debris, and a fallen tree lay across the creek at the south end of 1441 Bellevue Avenue. The one multiple family building across the creek and northeast of the other buildings is accessed by a wood pedestrian bridge; parking for this building is limited to the other (west) side of the creek. No drop inlets were noted at this location and it is assumed that surface water flows into the creek. Project Impacts Drainage at the site will be modified by construction of the previously described underground parking area, as well as the size of the proposed multiple family building and construction done to meet current City regulations. Although the surface water drainage, such as from rainwater leaders, currently discharges directly into the creek, the City policy requires that all surface stormwater run-offbe drained to the street and into the storm drainage system. Clean subsurface ground water from the depressed parking area can be pumped to discharge directly into Ralston Creek, provided that the water meets water quality standards and is approved by the Department of Fish and Game and the Regional Water Quality Control Board. Surface run-off from wet cars that enter the two-story below grade garage and any from water that may flow into the garage will be required to drain to the local sanitary sewer system due to the lower elevation of the parking areas and the possibility of contamination of the drain water from vehicles. The proposed development will replace the surface parking consisting of relatively impervious asphaltic concrete and landscaped areas with subsurface parking west of the creek. The existing multi -family building east of the creek will be replaced with a common area consisting of a patio and bark covered play areas. The existing drainage goes either to the local storm drain system or possibly, into the creek. Drainage for the proposed development will be pumped to the street to flow into the local storm drain system. As the proposed development will most likely have similar drainage measures to the existing, there should be no significant change in the quality of surface water runoff collected on -site. There may a minor increase in surface water flow west of the creek, because of the removal of most of the landscaped areas in that location. Significant changes arising caused by construction activities may impact the storm water quality, and will be discussed further below. The proposed development will change the type and method of drainage, and will be impacted by flooding during major storms. The flow of the creek and its hydraulic gradient will not be significantly -altered by the proposed development, because the retaining walls for the culvert beneath the existing apartment building at the southwest corner of the site will remain and the open channel area will be kept. Therefore, the construction will not increase the flood risk from the creek. The proposed finished floor for the living areas has an elevation of 32.5 feet, with the 100-year flood elevation of approximately 29.5 feet, which follows the FEMA guidelines for construction of residential structures in flood plains (minimum 2 feet above the flood elevation). However, the proposed depressed parking area will be approximately 10 feet below the bottom of the creek, and is approximately 16 feet lower than the 100-year flood level along the creek. Drainage for the below grade parking area will be dependent on the operation of sump pumps, by construction and maintenance of flood walls, and other drainage measures to prevent surface water from flowing into the below grade parking area during a major storm. Backup gas powered water pumps should be installed if the electrical powered water pumps fail to operate. These items are included as mitigations measures in the section below. The City Engineer 19 Initial Study Summary 1441-1445 Bellevue Avenue requires curb cuts to be designed so that they rise above curb top sufficiently to prevent water in the curb from flooding from the street into below grade garages. Sand bags would be a back up for extreme flooding conditions. If the garage does flood, the damage would be mainly to the parked cars and not to the concrete basement structure, and therefore, it is not considered to be a potentially significant impact. The tops of the existing concrete walls which contain the creek beneath the apartment building at the southwest corner of the site have elevations of approximately 29 to 31 feet above MSL (mean sea level), and in some portions are lower than the 100-year flood elevation. If these sections ofwalls are not raised, localized flooding may occur during a major storm, as the freeboard for the wall sections during a 100- year flood is less than one foot, and may aggravate the existing surface and subsurface drainage. Mitigations for these corrective actions have been included below to reduce the chance of flooding of the creek. Excavation for the depressed parking area will most likely be impacted if shallow groundwater is encountered, particularly if the excavation is accomplished during the winter months. During the geotechnical consultants site visits in March and August 2004, the creek had a few inches of water flow. It appears the summer water flow is coming from drainage from an office building garage located to the rear of the property. The borings drilled for the geotechnical investigation conducted by BAGG at the site in May, 2002 encountered groundwater at approximately 16 feet below the ground surface. Excavation that is lower than the creek bottom may require use of sheet piles or other impervious temporary soil retaining structures during excavation. There is a possibility that during peak runoff that the creek may spillover. Mitigation is listed below that will address the impact of this water spillover to less than significant. The basement will be supported on a drilled pier and grade beam foundation system. The drilled piers will extend from the grade beams approximately 12 to 14 feet below the ground surface constructed within the basement, which will be 25 to 30 feet below the ground surface. The piers would therefore encounter groundwater requiring that the water be pumped out of the pier holes just before placing the concrete, or that the concrete be placed by tremie method from bottom up, (the water would be displaced by concrete and forced out of the pier holes). There could be a situation at times where groundwater intrusion into the pier holes during construction may come into contact with concrete. This water can not be discharged into creek and would require a system for on -site treatment which would need to be reviewed and approved by the City Engineer. Minor stream flows during excavation can be diverted by constructing a temporary dam in the creek bed and forcing the water to flow into a closed pipe. This pipe wall would extend past the dewatering zone of influence and be placed within the creek bed. Dewatering of the basement and/or basement foundation excavations maybe accomplished by installing pump(s) in shallow sump(s) in the excavation. Water from the excavation would be directed to the streambed to flow into the diversion pipe. The location of the water discharge will depend on the quality of the water. Clean water obtained from the gravel drains located behind the garage retaining walls can be discharged into the creek where the creek channel is concrete lined. The volume of water is estimated to range between 0 to 5 gallons per minute, varying with the season. Surface water flow from the completed garage parking stalls which contains oil and grease from the parked cars, should be discharged into the sanitary sewer system. Water generated during construction of the basement garage that is filtered with gravel and filter cloth and needs to be treated on - site and discharged to the storm drain system as approved by the City Engineer. 20 Initial Study Summary 1441-1445 Bellevue Avenue Part of the Clean Water Act is the National Pollution Discharge Elimination System (NPDES) that regulates storm water discharge. In San Mateo County this program is administered through the Storm Water Pollution Prevention Program (STOPPP). Construction sites that disturb one acre or more of land are required to get a Storm Water Pollution Prevention Plan (SWPPP) or Notice of Intent from the Regional Water Quality Control Board. The subject property, when combined, is less than one acres, 0.56 acre (24,637 SF), therefore a SWPPP is not required. However, during construction best management practices (BMP's) must be used to reduced storm water run-off and construction erosion and sedimentation. Under STOPPP the project should also be designed to reduce long term water quality impacts by using site design and source control measures that will help keep pollutants out of the storm water runoff. The County's permit from the State Regional Water Quality Control Board contains new C.3 regulation. These new regulations establish a lower threshold for requiring site design and source control standards for development projects. As of February 15, 2005, Group #1 requirements will require that a new development or redevelopment project which creates, or replaces, one acre or more of impervious surface will be required to meet the new C.3 regulations. Group 2 will become effective August 15, 2006, and will reduce the standards set forth in Group 1 from one acre to 10,000 SF. The proposed development is less than one acre and would not fall under the Group 1 requirements. The proj ect would meet the criteria for the Group 2 requirements. However, because of the effective date Group 2 does not apply to this proj ect. Because this development is adjacent to Ralston Creek, the site is considered a sensitive environment. The project will be required to implement best management practices (BMP's) during construction to mitigate any possible impacts of construction on the creek. The storm water coordinator for the City is also suggesting site design measures that would reduce the long term water quality impacts such as reducing impervious surfaces, draining rooftop downspouts to splash blocks or bubble ups, and the use of landscaping as a storm drainage and treatment feature. In summary, the proposed development may be satisfactorily built with minimal impact to the existing hydrological conditions provided adequate mitigation measures for storm water protection and associated drainage and erosion control measures are adhered to. However, the construction of the proposed below grade parking area will be the most difficult to manage. Mitigation measures listed in the section below will reduce the impact on existing hydrological conditions to a less than significant level. Mitigation: • that all surface stormwater run-off shall be required to drain to the street into the storm drainage system; • that clean subsurface ground water encountered during excavation and pier drilling shall be discharged into Ralston Creek, provided that discharge into the creek is approved by the Department of Fish and Game and the Regional Water Quality Control Board; • that a subsurface drainage system shall be installed in the walls and/or foundation of the two-story below grade garage for the collection of ground water intrusion; this water shall be discharged into the creek, provided that it is approved by the Department of Fish and Game and the Regional Water Quality Control Board; • that the finished parking area (garage) surface drainage and run-off shall be required to drain to the local sanitary sewer system because of the possibility of contamination from vehicles; this drainage 21 Initial Study Summary 1441-1445 Bellevue Avenue system shall be connected to gas powered pumps connected to a self activating emergency generator; short floodwalls may also be required to prevent water from the creek spilling over into the below grade area; • that biodegradable fertilizer shall be used on -site due to the close proximity to Ralston Creek; • that minor stream flows shall be controlled by constructing a temporary dam in the creek bed and forcing the water to flow into a closed pipe, which shall extend past the dewatering zone of influence, also to be placed within the creek bed; dewatering of the basement and/or basement foundation excavations may be accomplished by installing pump(s) in shallow sump(s) in the excavation; water shall be directed to the streambed to flow into the diversion pipe; water discharge location will depend on the quality of the water; clean water obtained from the gravel drains located behind the garage retaining walls can be discharged into the creek where the creek channel is concrete lined. • that to minimize flooding and/or spillover of the creek during peak runoff, the existing concrete retaining walls beneath the apartment building at the southwest corner of the site, which will be exposed with the demolition of the apartment building spanning over the creek, shall be raised, as the western wall redirects the flow to a more northerly direction, and short floodwalls or earthen berms at the top of the open channel shall also be installed, as required; • that water that comes into contact with concrete during pier drilling or pouring shall not be discharged into the creek, and shall be treated on -site with treatment approved by the City Engineer, and shall be discharged as approved by the City Engineer; • that in order to minimize flooding in the excavation from shallow groundwater and spilling from the creek excavation for the below grade parking area shall be accomplished during the dry season, April 15th to October 15th; • that erosion and sediment control plans shall be submitted and approved by the City before issuance of a demolition, grading or construction permit; • that site work shall be limited to the dry months, from April 15 to October 15; • that prior to issuance of a demolition, grading or construction permit protective silt fences shall be installed along the open channel of the creek; the protective fence shall be installed between the top of the creek bank and at least two feet below the top of the areas to be graded, and also no lower than the ordinary high water line; • that prior to issuance of a demolition, grading and building permit the applicant shall obtain all necessary permits and approvals from the Department of Fish and Game and the Regional Water Quality Control Board, and shall provide a copy of these approval to the City of Burlingame. 5. AIR QUALITY SUMMARY: The proposed application is for a 16-unit multiple family condominium building to replace the existing 18 residential units on site. The overall housing density for this site will be reduced, therefore the total number of vehicle trips to and from the site will also be reduced. For this reason long term emissions from this site will be also be reduced as a result of this project.' The site is within walking distance of countywide bus and rail services, with several transit routes which run along El Camino Real, less than one -quarter mile from the site. The site is also two blocks from the Burlingame Avenue Commercial Area which offers neighborhood services, retail shops and grocery stores. The site is zoned for residential multi -family rental and condominium development. 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. 22 Initial Study Summary 1441-1445 Bellevue Avenue The short term air quality will be impacted as a result of the demolition of the existing five structures on the site and the construction of the new residential condominium building. The wood pedestrian bridge over Ralston Creek will also be demolished and re -constructed as part of this project. Prior to the demolition the structures are required to be surveyed by a specialist certified by the Division of Occupational Safety and Health. This survey shall include taking samples and testing all materials suspected of containing asbestos. Any materials containing asbestos in amounts greater than 1 % must be removed prior to demolition as required by Bay Area Air Quality Management District (BAAMD) Regulation 11, Rule 2, paragraph 303.1 through 303.13. Particulate matter less than 10 microns in size (PMIo) is of most concern to the Bay Area Air Quality Management District (BAAMD). PMIo can be generated during various construction actives, including demolition, grading, excavation, and from vehicle and equipment exhaust. The construction equipment and materials can also emit carbon monoxide and ozone precursors. However the Bay Area Air Quality Management District standards state that housing projects with 530 units or less will not produce potentially significant levels of these emissions. This proposal is well below the BAAQMD thresholds and will not produce potentially significant emissions as a result of construction. Mitigation: • that demolition of the existing structures and any grading or earth moving on the site shall be required to receive a permit from the Bay Area Air Quality Management District prior to issuance of a demolition permit from the Burlingame Building Division; and all requirements ofthe permit shall be complied with during construction; • that all active construction areas shall be watered at least twice daily, especially during the demolition and excavation phase of the project; • that water that may run off the site due to the dust control measures required shall not be allowed to run-off into Ralston Creek or into the storm drain system; • that sandbags shall be installed around the perimeter of the site to prevent water run off from the dust control activity from spilling onto the public right-of-way or on to adjacent properties; • that trucks to and from the site hauling soil, sand or other loose material shall be covered or that a minimum of two feet of freeboard shall be maintained; • that during construction soil stabilizers shall be applied to unpaved access roads, parking areas and staging areas at the construction site; • that at a frequency required by the Engineer, the paved access road, parking areas and staging areas at the construction site shall be sprayed with water to maintain a clean areas; • that the public street shall be swept as required by the City Engineer with a water sweeper if visible soil materials are carried beyond the construction site; • that excavation and grading activities shall be suspended immediately if winds exceed 25 mph; • that sandbags or other erosion control measures shall be installed to prevent silt runoff from the site to public roadways; • that any demolition on this site shall comply with BAAQ MD Regulation 11, Rule 2, which governs the handling of asbestos -containing materials; this rule requires that a survey be done of all the building materials to be removed prior to commencement of any demolition; the property owner shall be responsible for having a professional on -site that is familiar with the implementation ofRegulation 11, Rule 2 of the BAAQMD to supervision the removal or demolition of an asbestos containing 23 Initial Study Summary 1441-1445 Bellevue Avenue materials; • that during demolition and construction all hazardous materials shall be stored, handled and disposed of properly; and that any coating or sealant to be used shall comply with the BAAQMD Regulation 8, Rules3 and 51 for volatile organic compound (VOC) content, which governs the application of architectural coatings and adhesive and sealant products. 6. TRANSPORTATION/CIRCULATION SUMMARY: Setting The site is an interior infill lot on Bellevue Avenue, between Almer Road and El Camino Real. Bellevue Avenue and Almer Road are collector streets serving high density residential uses and as access to commercial uses. El Camino Real, a state highway, is a major arterial roadway for the region. El Camino Real is located approximately 500 feet west of the subject property, Almer Road is located less than 100 feet east of the subject property. Bellevue Avenue is 36 feet wide and the speed limit is 25 miles per hour. On -street parking on both sides of the street is limited to two -hours. The applicant has submitted a traffic and parking study prepared by Hexagon Transportation Consultants dated January 30, 2004. The study looks at the potential traffic impacts from the change in the number of dwelling units on the site, as well as an analysis of the on -site and on -street parking and circulation. Project Impacts Trip Generation: The study uses the trip generation rates for multiple family development in the Institute of Transportation Engineers (ITE) Trip Generation manual, seventh edition, 2003. The study compares the peak hour traffic expected from the existing 18 apartment units to the peak hour traffic from the proposed 16 new condominium units. The rates shown in the ITE manual indicate that there is a higher trip generation rate for rental units than for condominiums (owner occupied) units during the PM peak hour. The trip generation estimated for the project indicated that there would be approximately 2 fewer AM peak -hour trips and 3 few PM peak -hour trips. The traffic volumes at the site driveways will be less than the existing volumes that the driveways on each site (two separate properties now), with one inbound and six outbound vehicles in the AM peak hour and six inbound and two outbound vehicles in the PM peak hour. Site Access: The existing site has access by two driveways, one for each of the two properties. The proposed project would also include two driveways. One driveway is proposed at the eastern end of the site to access the underground garage, this driveway is 30 feet wide. Burlingame Municipal Code 25.70.025 (2)(b) requires either one 18 foot wide driveway or two twelve foot wide driveways for access to parking in areas with more than 30 vehicles. The second driveway provides access to the semi -circular driveway in front of the new residential condominium building. It is 16 feet wide and is located on the western portion of the lot. The semi -circular driveway connects to the eastern driveway. The purpose of the semi -circular drive is to provide passenger drop off at the entrance and to provide a place for delivery trucks to park off the collector street to make deliveries or pickups. The project complies with Municipal Code Section 26.30.070(b)(2) requiring temporary parking for service vehicles in the driveway between the front property line and the face of building for proj ects of 3 or more units. The study notes that there is adequate sight distance at the driveways, except for the visual obstruction caused by cars parked by the driveways at the curb on the street. The Burlingame City Engineer reviewed the proposal and has recommended that the 30 foot driveway be reduced in size to 24 feet and shifted east. This would create one additional parking space, for a total of two spaces, in between the two driveways. The net loss of on- 24 Initial Study Summary 1441-1445 Bellevue Avenue street parking in front of this site will be one parking space. The reason for the suggested change however is to eliminate the jog, or S, that the proposed driveway does right before the street. This is an unsafe maneuver that the City Engineer feels can be remedied by having a straight exit path out of the garage. The City Engineer also notes that having a 30' wide driveway at the proposed location may confuse approaching vehicles about right-of-way onto the site. The driveway could create a situation where a vehicle is exiting the circular driveway, as another vehicles is entering the garage conflicts with a vehicle coming up the ramp out of the garage. To avoid this possible scenario the City Engineer suggests that the driveway be reduced in width to 24 feet; that directional arrows and signage shall be placed on the circular driveway indicating one-way; and a yield sign or striping shall be placed near the end of the circular driveway where it ends and merges for exit with the driveway access to the garage. The City Engineer is also requiring that the driveway elevations at the garage entrance be 12 inches above the gutter flow line on Bellevue Avenue to reduce flooding from the street into the garage. On -site Circulation: The Hexagon study also includes an analysis of the on -site circulation. The study notes that the street -level circular drive can serve as a drop off area for residents and delivery trucks, with enough room for two to three vehicles in tandem. However, since the drive aisle of the semi -circular driveway varies from 12 to 16 feet in width, it cannot accommodate longer term parking because another vehicle would not be able to pass a parked vehicle. The study further notes that the slope of the ramp to the below -grade parking meets the City's regulations regarding ramp slopes. The width of the ramps is 18 feet, which meets the City's requirements for two way traffic. The ramps to the two levels of below grade parking will have a maximum grade of 18.3 percent, with 8 percent transitional slopes at each end. Code section 25.70.025(2)(d) of the zoning ordinance requires review of driveways slopes in excess of 15 percent but less than 20 percent by the Public Works Department. The City Traffic Engineer notes that 15 percent is generally the most comfortable slope for drivers. He notes that the proposed 18 percent slope will work with the transition slopes at the top and bottom of the slope. The vertical clearance for the ramp for level 1 is shown as 8 feet 2 inches and for level 2 is shown as 7 feet 10 inches, which is in compliance with City regulations, Municipal Code Section 25.70.025(2)(b) which requires a minimum vertical clearance of 7 feet. The parking aisle within the underground garage terminates in a dead end. The end stall in a dead-end garage needs to be wider to allow for adequate maneuvering to exit in a forward direction. The end space is proposed to be ten feet wide, which is required for a space next to a wall. Planning staff has determined that this space does meet City standards because it can be exited in three maneuvers or less. The guest spaces in the garage are shown on the first level of parking near the entrance. The parking study notes that this is an appropriate location because there would be a problem if a guest were to try to find a space near the end of the aisle and discover that there are no spaces available. It is not possible for a car to turn around at the end of the aisle if all spaces are full. It would be helpful if signs could be posted at the guest parking area indicating that the remaining spaces are not for guest parking, to prevent guests from inadvertently entering the dead-end aisle. There should also be an intercom with a buzzer located at the garage entrance to allow guests of 1441-45 Bellevue to contact residents to automatically open the garage door so that guest can have access to the guest parking spaces located in the garage. A key pad should be provided for residents so access to the garage is controlled. 25 Initial Study Summary 1441-1445 Bellevue Avenue Parking supply: The project proposes to provide 43 on -site parking spaces, where the zoning code requires 37 parking spaces (34 spaces based on the number of bedrooms for residents, plus 3 guest parking spaces). There are two disabled accessible spaces proposed, as required by the California Building Code. Therefore the applicant is proposing 6 additional spaces beyond those required by the zoning code. There are 39 standard parking spaces, 9 feet wide by 20 feet deep, proposed within the two level below grade garage. Spaces adjacent to a wall require an additional foot of width to allow for maneuvering, all of the end spaces meet this requirement. Three parking spaces will be compact with an 8 foot width and 17 foot depth. The two van accessible parking spaces have an 8 foot loading areas as required by the California Building Code. All of the parking spaces are 90 degree parking and have the required 24 foot back up space. All spaces can be accessed (in and out) in three or less maneuvers as required by Code Section 25.70.025(l)(c). Based on the analysis in the traffic study, this project will decrease the trips generated in the area. All arterial, collector, and local roadway systems in the City have adequate capacity to accommodate the existing traffic or trip generation produced by the existing 18 rental units. Therefore the reduction of two units and shift to 16 condominium units will have no additional impact on the existing service levels. The proposed condominium building meets the on -site parking requirements established in the Zoning Code and in the most recent Condominium Ordinance. Pedestrian Access to and from Parking There are three exits for pedestrians from the garage to street level or into the building; an elevator and adjacent stairwell located at the center of the building, and another stairwell located at the northwest corner of the building. Although pedestrians could use the vehicular access ramp to exit the garage, it will be steep and pedestrian use is highly discouraged. The traffic and parking study includes a recommendation that signs be posted at both ends of the ramp warning against the use of the ramps by pedestrians. There was additional concern expressed in the report about the handicap -accessible parking space and passenger loading area being located across the main drive aisle from the elevator and near the access ramp. It was suggested that the project architect consider relocating these spaces to the south side of the drive aisle. In response the project architect has submitted revised plans which relocate the handicap - accessible parking spaces with the passenger loading to the south side of the drive aisle so they are located adjacent to the elevator lobby. All disabled accessible parking spaces will be located on the first level below grade. Construction Parking and Traffic The applicant has submitted a letter stating their plans for construction staging and parking during construction. All construction materials will be staged on the subject property. They are planning on having a forklift at the site to help make this possible. Dumpsters necessary for the demolition and construction will remain on the street for no more than two or three days at a time each week. The workers that will be performing the demolition and construction on this site will park either on the construction site, or 2 blocks northwest of the site in public parking lots. The number of construction workers on -site will vary during different stages of construction. An estimate of the number of workers needed during the various construction stages is: demoliton-2; excavationion/underpinning-6; foundation- 6; framing-12; plumbing/electrical-6; sheetrock-8; trim-6; and finishes-8. It is anticipated that the average 26 Initial Study Summary 1441-1445 Bellevue Avenue number of workers that will on -site at once will be between 7 and 10. Mitigation: • that in order to reduce the occurrence of visitors in the below grade garage from entering a dead-end aisle with no maneuvering space to exit, a sign shall be posted near the guest parking spaces which directs visitors to the area designated for guest/visitor parking; all parking spaces in the below grade garage in this area shall be assigned directly to residential units on the site and shall be closely managed by the homeowners association; • that signs shall be posted at both ends of the ramp accessing the below grade parking warning pedestrians against the use of ramps for pedestrian travel; • that the proposed 30 foot driveway shall be reduced to 24 feet, or a size approved by the City Traffic Engineer, and shall be shifted east; • that the circular driveway at the front shall have proper signage indicating that it is a one-way driveway with the entrance on the western driveway; • that the circular driveway at the front shall have yield signage at the end where it merges with the driveway that provides entrance and exit to the underground garage; • that the driveway elevation at the garage entrance shall be 12 inches above the gutter flow line on Bellevue Avenue or at an elevation approved by the City Engineer; • that all dumpsters located on the public street shall obtain the necessary encroachment permits from the City of Burlingame Public Works Department prior to locating the dumpsters on the street; • that all personal involved with the demolition and/or construction of the proposed project at this site shall be required to park in the public parking lots and garage in the immediate vicinity; • that since all guest parking is provided in the below grade garage there shall be an intercom with a buzzer to each unit, and a keypad access shall be provided so each tenant can operate the security gate to the garage on demand. 7. BIOLOGICAL RESOURCES SUMMARY: The site was fully developed and used forresidential uses. In 1926 the structure to the west was built and in 1936 the structure on the eastern portion of the site was built. A large part of the vegetation on this site is ornamental including a maple, cherry -plum, Portugal laurel, walnut, juniper, English ivy and bird -of -paradise. There are also native species on the site including coast redwood, coast live oak and a cypress. Burlingame Code Section 11.06 defines a protected tree as any tree with a circumference of 48 inches or more when measured 54 inches above natural grade. There are three protected size trees that are proposed for removal as a part of this project: a cedar, a magnolia and a date palm. Because the date palm falls within the footprint of the proposed building a tree removal permit is not necessary. However the cedar and magnolia will both require a protected tree removal permit from the Burlingame Park Department. The proposed landscape plan for the project complies with the on -site reforestation requirements. There are several other trees located on -site that will remain during and after construction. For these trees tree protection measures shall be installed on the site prior to the start of demolition on the site and shall remain installed throughout construction. There is a 40 inch coast redwood tree located in the center of the property towards the rear. The arborist report recommends that exploratory excavation be done on what is now an asphalt driveway to determine the extent of root growth in area around this tree. If extensive roots are found in the area the plan may need to be modified to change the shape of the building to preserve construction damage to the roots, or if possible the foundation plan may need to be modified to 27 Initial Study Summary minimize damage to the roots of the redwood tree. 1441-1445 Bellevue Avenue Ralston Creek flows through this site and is located primarily at the rear. This creek carries runoff from the watershed in the Burlingame Hills to San Francisco Bay. On this site the streambed is channelized, lined with stone wall. There is a small portion of the creek that flows through concrete retaining walls under and existing building on the eastern border of the property. The channel contains concrete, debris and small amounts of silt, without vegetation. English ivy covers the banks above the stream. The landscape plan for this project notes that the English ivy along the creek will be replaced with native ground cover such as wild lilac. During a biological resources survey prepared by LSA Associates no wildlife species were observed and no birds nests were found on the site. Birds such as English sparrows and Brewer's blackbirds, which are common in urban environments, may periodically nest or forage on this site. Because this area has been developed for many years and has had regular human disturbances the area has a low habitat value for wildlife. There were no sensitive biological resources identified on the site that would be adversely affected as a result of this proposal. Although Ralston Creek itself will not be altered by this project, the applicant will be removing and replanting existing vegetation along the creek bed. The Fish and Game Code Section 1602 states that when the bed, bank or associated vegetation along a water body is altered that a Streambed Alteration Permit must be issued by the California Department of Fish and Game prior to starting work on the site. The City of Burlingame will require a copy of the approved Streambed Alteration Permit prior to issuance of any grading, demolition or construction permits related to this project. The project may also be subject to review of the Army Corps of Engineers and the California Regional Water Quality Control Board. Additional mitigations may be required by these agencies. Mitigation: • that prior to issuance of a grading, demolition, or construction the project shall comply with the City's tree protection and urban reforestation requirements as approved by the City Arborist; • that the property shall apply for protected tree removal permits as per the City Arborist's August 26, 2002 memo; • that the property owner shall obtain the necessaryreview and permits from the California Department of Fish and Game, Army Corps of Engineers and the California Regional Water Quality Control Board and provide copies of such approvals prior to issuance of the demolition and/or building permits; • that tree protection measures shall be installed under the supervision of a licensed aborist prior demolition or construction and shall be inspected by the City Arborist; • that prior to demolition or construction any trees that will likely suffer root loss or soil compaction as a result of this proj ect shall be deeply irrigated and fertilized; and a long term maintenance plan shall be prepared and submitted to the City Arborist for approval; • that protected trees that will have soil fill or the construction of hardscape within their root zone as part of this project shall have a root aeration system installed prior to said fill or hardscape; and all hardscape shall be of pervious material; • that all trees which border any area where grading or soil compaction is likely to occur shall be mulched to depth of 8-16 inches or as required and approved by the City Arborist or as required and W Initial Study Summary 1441-1445 Bellevue Avenue approved by the City Arborist; • that any trees located in areas where construction traffic is likely to occur shall be mulched to help reduced soil compaction as required by the City Arborist; • that soil siltation fences shall be installed and maintained to keep soil from disturbing areas out of the root zones of protected trees as required and inspected by the City Arborist. 8. ENERGY AND MINERAL RESOURCES SUMMARY: All gas and electric services are in place to the site with capacity to handle the increase in the number of overall bedrooms on -site, from 20 bedrooms to 41 bedrooms. Although the proposed structure contains units that are significantly larger than the existing, ranging in size from 859 SF to 3,900 SF, the incremental increase to the use of energy is insignificant primarily because the new construction will comply with Title 24 requirements, while the dwellings removed were built before these energy conserving requirements. This project will also result in only one main structure where the dwellings will be located, there will be no dwellings located at the rear of the property on the other side of the Ralston Creek, so with this proposal services will be limited to one building. 9. 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. In the case of residential buildings having four or fewer dwelling units, the owner/operator can sample and test suspected asbestos containing materials rather than hiring a certified consultant. Prior to the demolition, the structures are required to be surveyed by someone certified by the Division of Occupational Safety and Health. This survey shall include tasking samples and testing all materials suspected of containing asbestos. If anymaterials containing asbestos in amounts greater than 1 % are found Bay Area Air Quality Management District shall be notified immediately and all asbestos must be removed prior to demolition as per (BAAMD) Regulation 11, Rule 2, paragraph 303.1 through 303.13. Any hazardous materials to be used during construction shall be properly handled and stored in compliance with Central County Fire Department Requirements. 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. BMP's (best management practices) are required to ensure that runoff from the site does not contribute to pollution of adjacent waterways. The Fire Marshal has required that the building be protected by an approved automatic sprinkler system and a fire alarm system which is required to be monitored by an approved central station. This requirement will reduce potential fire hazards for the project. Burlingame also participates in a county- wide mutual aid program for large-scale fires and related emergencies. The City of Burlingame's water system that serves this site is rated as a Class 3 system by the Insurance Services Offices, and is adequate for fighting fires at this infill location. Mitigation: • that the applicant shall install fire sprinklers and afire alarm system monitored by an approved central station as required by the Fire Marshal prior to the final inspection for building permit; • that any demolition on this site shall comply with BAAQMD Regulation 11, Rule 2, which governs 29 Initial Study Summary 1441-1445 Bellevue Avenue the handling of asbestos -containing materials; this rule requires that a survey be done of all the building materials to be removed prior to commencement of any demolition; the property owner shall be responsible for having a professional on -site that is familiar with the implementation ofRegulation 11, Rule 2 of the BAAQMD to supervision the removal or demolition of any asbestos containing materials; • that during demolition and construction all hazardous materials shall be stored, handled and disposed of properly; and that any coating or sealant to be used shall comply with the BAAQMD Regulation 8, Rules3 and 51 for volatile organic compound (VOC) content, which governs the application of architectural coatings and adhesive and sealant products. 10. NOISE SUMMARY: Setting The site has been developed for over 78 years with residential dwellings. The proposed project will not permanently increase the existing ambient noise levels because it is replacing structures of similar use, which will comply with current construction standards, including increased insulation, which also provides for noise attenuation. The applicant submitted a noise and vibration study, Environmental Noise & Vibration Impacts Elevations for Chateau Bellevue prepared by Nigel Breitz Acoustics. This report was reviewed by a third party consultant TRA (Thomas Reid Associates). TRA determined that the approach, methodology and documentation in the report are appropriate. In order to establish a baseline the noise study prepared for this project measured the average ambient noise levels at the front and rear property lines on the site during the week. The L,onoise levels at the front are between 55 dBA and 60 dBA and at the rear they in the 50 dBA to 55 dBA range. In addition, the site is located outside the designated noise -impacted area from San Francisco International Airport. The proposed 16-unit condominium building will be replacing 18 existing apartment units currently located on the site so fewer people will be exposed to noise impacts. Based on the information in the traffic and parking study prepared for this project there will be approximately 20 fewer vehicle trips per day, therefore there will be less noise associated with vehicle traffic to and from the site. Noise measurements are reported as A -weighted levels, called dBA, where speech is usually 65 dBA. CNEL is the Community Noise Equivalent Level metric, and is calculated by averaging hourly Leq levels over each hours of the day. LeQ is a metric used to denote noise levels averaged over some period of time. Title 24 of the California Code of Regulations (CCR) requires an acoustical study for residential development if exterior CNEL levels exceed 60 dBA on a proj ect site. For residential land uses where the project outdoor noise levels are between CNEL 60 dBA and 70 dBA they are defined as "Conditionally Acceptable". These noise levels may be permitted after a detailed analysis and the inclusion of noise reduction provisions in the exterior shell of the design. The analysis to be done, as per CCR, states that acoustical analysis must demonstrate how interior noise levels not more than 45 dBA CNEL can be achieved in habitable rooms. If the 45 dBA CNEL can only be achieved by shutting the windows then other ventilation must be provided for fresh air and interior noise level. Project Impacts Construction Noise: The City of Burlingame, General Plan, Noise Elements states the community noise standard: no one shall be allowed to cause any noises to be emitted past the property line to create any noise that would cause the ambient Lto noise level to be increased by more than 5 dBA. As with any construction project, during construction noise levels will temporarily result in ambient levels greater than 30 Initial Study Summary 1441-1445 Bellevue Avenue the existing average ambient levels. During construction hours the Llo noise level will typically range from 65 dBA to 75 dBA, and at times could reach 85 dBA to 90 dBA for brief periods. So noise levels will exceed the existing ambient level by 15 dBA to up to 90 dBA during construction. Because it is possible that multiple pieces of equipment will be operating simultaneously, and at times maybe required to operate closer than 15 feet from the property line for short periods of time, the maximum noise may increase briefly to 90 dBA. This is an estimate of aggregate noise levels. This maximum could also be the result of noise reflections off of close neighboring buildings. Reflection of sound off of the adjacent building typically can increase measured noise level by up to 3 dBA. The proposal includes significant excavation for a two-story below grade garage. However piles will not be driven into the ground for the garage. Instead poured in place piles will be used, the holes will be pre - drilled and piles will be placed into the holes and concrete will be poured around the piles. A large tracked excavator will be used to remove the existing structures and foundations, and has a noise level of 80 to 85 dBA at 15 feet from the equipment. The other equipment to be used on this project includes dozers, concrete mixers, and trucks which have noise levels that are about 75 dBA at 50 feet from the equipment. The City of Burlingame Noise Element contains a table that lists the maximum allowable noise levels from construction equipment. This data is presented in peak noise level in dBA and is measured at distance of 50 feet from the said equipment. However, the report submitted measures the noise level at 15 feet from the equipment. Because this lot is only 123 feet at its widest portion, the noise level should be considered at closer distances. The noise study prepared for this project notices that noise for a localized source in a field radiates spherically. As the noise radiates it decreases by 20 log, meaning that from a 15 foot distance to a 50 foot distance there would be a decrease of —1 OdB. Therefore, the noise level of an excavator operating 15 feet way is 85 dB, and is in principal the same as a level of 75 dB for an excavator operating at a 50 foot distance (which is the maximum allowed in Table 4-6 of the City of Burlingame Noise Element). At the time of the preparation of this document there was no contactor on board to verify the length of time that the excavator will be on -site. However, the project architect anticipates that the excavator will be used for approximately 8 weeks. In order to mitigate the noise level of the excavator, the work with this piece of equipment shall be limited to only 6 hours per day, not before 9:00 a.m. and not later than 3:00 p.m.. The other pieces of equipment proposed for use on this site will likely include a backhoe, concrete mixer, concrete pump, emergency electric generator, one or more compressors, one or more j ack hammers, and saws. This type of equipment will generally operate at 75 dBA at 50 feet, consistent with the City of Burlingame Noise Element. Construction Vibrations Impacts: The Environmental Noise & Vibration Impacts Elevations for Chateau Bellevue prepared by Nigel Breitz Acoustics for the proposal also looked at vibration impacts caused by the construction. The study used the criteria of the American Association for Highway and Transportation Officials (AASHTO) to measure building damage from ground vibration. This criteria states that superficial damage such as cracks in paint or plaster, begins to occur when peak ground vibration velocities are greater than 0.2 in./second (inches of movement per second). However, it is common for people to become disturbed when ground vibrations levels exceed half of this level 0.1 in./sec. 31 Initial Study Summary 1441-1445 Bellevue Avenue Vibrations caused by construction are anticipated to be felt by neighbors during demolition of the existing structures when concrete is removed, during the pre -drilling of holes for piles and when excavation is done closer than 30 feet from neighboring properties. However, according to this study peak ground vibrations levels are proj ect to remain significantly below the criterion for superficial damage at 0.2 inches per second. Ground vibrations should be monitored when the activities of concern (during demolition of the existing structures when concrete is removed, during the pre -drilling of holes for piles and when excavation is done closer than 30 feet from neighboring properties) begin. The vibration monitoring should begin when the initial activity is located away from the neighbors in order to project the levels of vibrations that will be created when the work is located a few feet from the neighbors. The monitoring necessary would use a ground vibration measuring system including transducer that must be calibrated traceable to the Nation Institute of Standards NIST. Other instruments used to do this monitoring include a (linear) broadband measuring system and an octave band or fraction octave band spectrum analyzer. A Construction Coordinator should be appointed prior to issuance of demolition and building permits for this project. He or she should be available to neighbors through out the construction process. All construction must abide by the construction hours established in the Municipal Code, which limit 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. There shall be no construction on holidays. All construction activity that will result in L,o noise levels of 85 dBA or higher shall be limited to the hours of 9:00 a.m. to 3:00 p.m. Monday through Friday, to reduce the impact of the intense construction noise and vibration to 6 hours per day only. Noise impact on residents after construction: The noise measurements taken at the existing site indicate that the site is already subject to noise from local road traffic, aircraft, train, and the discharge of water into Ralston Creek from the office building basement that sits behind the subject property. The L,onoise levels at the front are between 55 dBA and 60 dBA and at the rear they in the 50 dBA to 55 dBA range. The projected CNEL at the front of the site is 59 dBA and 57 dBA at the rear of the site. These projections are for the lower floors though, because they will be shielded from existing noise sources by the neighboring buildings, therefore they will required no noise attenuation features other than Title 24 requirements. The proposed 4th floor however will not be shielded from the adjacent buildings and is anticipated to have exposure to a CNEL of 60 or 61 dBA, and would required noise attenuation features to achieve an interior CNEL of 45 dBA. These features would include stucco exterior, acoustical lining in exterior walls, a minimum of STC-31 windows or greater (STC-33 or STC-34 ) with proper mechanical ventilation. It is assumed that with the use of these mitigation measures, that noise impacts to the residents in this condominium building would be less than significant. Mitigation: • that all construction shall be done during the hours of construction imposed by the City ofBurlingame Municipal Code; these hours are between 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. There shall be no construction on holidays; construction activity that will result in L,o noise levels of 85 dBA or higher shall be limited to the hours of 9:00 a.m. to 3:00 p.m. Monday through Friday; • that noise emission levels from construction and demolition on the site shall not exceed the values listed in table 4-6 of the City of Burlingame's General Plan Noise Element; 32 Initial Study Summary 1441-1445 Bellevue Avenue • that at no time shall the noise levels due to construction exceed levels greater than 90dBA; • that ground vibration levels 3 feet from the nearest occupied residential structures shall not exceed 0.1 in./sec. and vibrations shall be monitored during the demolition of the existing structures when concrete is removed, during the pre -drilling of holes for piles and when excavation is done closer than 30 feet from neighboring properties ; • that a Construction Coordinator shall be appointed prior to issuance of demolition and building permits for this project; the name and phone number of this coordinator shall be provided to the neighbors and to the Planning and Public Works Departments; the Construction Coordinator shall be responsible to the most practicable extent possible to mitigate construction impacts; • that all internal combustion engines operating on this subject property shall be fitted with noise suppression mufflers; • that the method of construction and materials used in construction shall insure that the interior noise level within the building and inside each unit does not exceed 45 dBA in any sleeping area; • that the proposed 4ch floor shall include noise attenuation measures to achieve an interior CNEL of 45 dBA, these features would include some or all of the following: stucco exterior, acoustical lining in exterior walls, a minimum of STC-31 windows or greater (STC-33 or STC-34 ), and proper mechanical ventilation. 11. PUBLIC SERVICES SUMMARY: Because the project is infill, and represents a decrease in the resident population on the site because of the reduction of two units (from 18 rental units to 16 condominium units) and is located on an already developed site, the existing public and governmental services in the area have capacities that can accommodate the proposed 16 condominium units. 12. UTILITIES AND SERVICE SYSTEMS SUMMARY: Settin There is a new 10-inch sanitary sewer main that was installed in January 2005 on Bellevue Avenue that connects to a 12-inch sanitary sewer main in California Drive and extends ultimately to the wastewater treatment plant located near San Francisco Bay in Burlingame. There is a storm drain at the intersection of Almer Road and Bellevue Avenue that connects to a 6' x 6' box culvert that ultimately flows to San Francisco Bay at the Burlingame Lagoon. This culvert empties into Ralston Creek under the street on Bellevue Avenue. This is the creek that runs through the rear of the property. The domestic water line runs down Bellevue Avenue and currently serves this site is a 6-inch cast iron pipe. This line comes down Bellevue from the west, and serves the other multi -tenant buildings on this block. The proposed project will be served by existing utilities in place in the area, or will be required to connect to these systems. During demolition, the existing underground utility lines to be abandoned shall be identified, removed and the ends shall be capped outside of the building envelope. All new utility connections (laterals) to serve the site and that are affected by the development will be installed to meet current municipal code standards; sewer laterals from the main onto the site to serve the new structure will be checked and replaced as required by the Public Works Department. The current solid waste service provider is Browning Ferris Industries (BFI). Waste collected in Burlingame is hauled to Ox Mountain Landfill. 33 Initial Study Summary 1441-1445 Bellevue Avenue Project Impacts Although the surface water drainage, including from rainwater leaders from this site, currently discharges directly into Ralston. Current City policy requires all surface run-off to drain to the street into the storm drainage system. The storm water from the proj ect will drain to the street, then it will flow down the curb and gutter and into the 6' X 6' box culvert that connects with the Ralston Creek culvert east of the site. Because of the below -grade parking garage included in the project, the City Engineer requires that an electric sump pump system and a back up emergency generator to power the system be installed. Clean subsurface ground water which collects along the outside walls of the below grade garage can be pumped to discharge into Ralston Creek, provided that this disposal is approved by the Department of Fish and Game and the Regional Water Quality Control Board. Drainage into the two-story below grade garage and surface run-off from wet vehicles that enter the below grade parking garage will be required to drain to the local sanitary sewer system because of the possibility of petroleum product contamination. In order to have the pressure to serve all of the fixtures and the fire sprinkler system in the new building the existing 6-inch cast iron pipe domestic water line in Bellevue may need to be replaced with a larger service line. This will be determined after the applicant prepares a water demand study as required by the Public Works Department for the proposed building prior to obtaining a building permit. On -site recycling of west stream is required and trash enclosures must be appropriately sited and accessible to Browning Ferris Industries (BFl). Construction activities would generate waste during the construction phase. The general contractor would be required to prepare and execute a recycling plan to reduce demolition and construction material in the waste stream. Recycled construction waste shall be transported 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 per cent 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 prior to issuance of a demolition permit. It is required that recycling records documenting compliance shall be kept and submitted to the City prior to scheduling the final inspection of the project. Mitigation: • that the contractor shall submit the "Recycling and Waste Reduction" form plan to the Burlingame Building Division that demonstrates how 60 percent of construction demolition material will be diverted from the waste stream to be approved by the Chief Building Official and the applicant shall be required to document implementation of the recycling before a final inspection can be scheduled; • that all surface storm water runoff created during construction and future discharge from the site shall be required to meet National Pollution Discharge Elimination System (NPDES) standards as adopted by the City of Burlingame and shall be directed as required by the Department of Public Works; • that sewer laterals from the site to the public sewer main shall be checked and shall be replaced to city standards as required by the Public Works Department; • that all abandoned utilities and hookups shall be removed as directed by the City Engineer; • that storm water run-off shall drain from the site to the street into the storm drain system; • that clean subsurface ground water into the depressed parking area shall be pumped to discharge into 34 Initial Study Summary 1441-1445 Bellevue Avenue Ralston Creek, provided that this is approved by the Department of Fish and Game and the Regional Water Quality Control Board; • that drainage and run-off into the two-story below grade garage shall drain to the local sanitary sewer system due to the lower elevation of the parking areas and the possibility of contamination from vehicle drainage; • that the applicant shall prepare a water demand study for the proposed building prior to obtaining a building permit to determine the adequacy of the existing domestic water line to supply the proposed condominium building as well as the required fire sprinkler system for the building; if it is determined that the domestic water line needs to be increased the applicant shall replace the water line in the street to city standards as required by the City Engineer. 13. AESTHETICS SUMMARY: The proposed sixteen -unit condominium building would replace five structures with similar uses on two lots. The project will merge the two lots and develop them with one structure with access to Bellevue Avenue via a semi -circular driveway at the front of the building. In this particular location, the land is flat and the area fully developed; no distant views or vistas are present. The proposed four-story condominium building inter] ects a break in the skyline by being placed between a three-story building to the left, 1435 Bellevue Avenue which is approximately 36 feet in height, and a three-story building to the right, 1457 Bellevue Avenue which is approximately 37 feet in height. The proposed building will have a mansard roof with arch top dormer so that the fourth floor is set within the roof formation to reduce the appearance of the four story building by tucking the fourth floor into the roof formation. The building design incorporates balconies, delicate wrought iron detail, and trims, moldings and other decorative architectural elements that set it apart from the surrounding structures. The windows will be wood framed with mullions, and the roof will be slate. The exterior material proposed is stucco, but the base of the building will have stone veneer detailing with stone quoins. This residential condominium building has been designed in a manner that is consistent with the existing size and mass of existing structures in the area and complies with the regulations for mass and bulk contained in the R-4 zoning regulations. The R-4 zone has a 35 foot height limit, with a conditional use permit for heights up to six stories or 75 feet in height. The applicant is requesting a conditional use permit for a proposed height of 45' 8". Existing Condition: A shadow simulation was done on the existing buildings located at 1441 and 1445 Bellevue Avenue using AutoCAD 3D. Field measurement were used for the adjacent and existing buildings and for placing them in the appropriate locations within their sites. This study concluded that the current buildings on -site have the most shadow impact on December 21 at 10:00 a.m., 12:00 p.m. and 3:00 p.m. when 1441 Bellevue casts a shadow on the northeast corner of the building 1435 Bellevue Avenue. At 3:00 p.m. this impact is most intense when the front building at 1441 Bellevue Avenue casts a shadow on the first floor of the right side section of the building at 1435 Bellevue, this is the portion that is setback approximately half way down the right side property line nearest 1441 Bellevue. There is no shadow impact from the existing structures at 1441 and 1445 Bellevue on either 1435 or 1457 Bellevue for the following times: March 21, June 21 (DST) and September 21 (DST) at 10:00 a.m., 12:00 p.m., and 3:00 p.m.. However, on March 21 and September 21 (DST) at 10:00 a.m., 12:00 p.m. and 3:00 p.m. a shadow is cast from 1457 Bellevue onto the entire south face of the existing building at 1445 Bellevue. 35 Initial Study Summary 1441-1445 Bellevue Avenue Light and Shadows: The applicant conducted a shadow analysis of the proposed structure, as well as a comparison with the shadows which would be cast by a three story building of the same configuration. The applicant created shadow simulations using two different methods. A three-dimensional model of the proposed structure was made, and using the Pacific Gas & Electric Company (PG&E) Heliodon, shadow simulations were generated. In addition, the applicant has provided computer -generated shadow simulations using AutoCAD 3D modeling Version 2000. Thomas Reid Associates (TRA) reviewed the shadow studies prepared by Dale Meyer Associates to determine if the shadow lengths and angles depicted were accurate. TRA's analysis determined that the methodology of each report meets industry standards and appears to be appropriate to show the shadow impacts of the project. When determining the impact of shadows, the time of day that is most critical is the period between 10:00 a.m. and 3:00 p.m., when the impacts are the most noticeable because sunlight is greatest and its loss from shadows cast would be the most adverse. The simulations for both the four-story project and the three- story alternative show the shadows at 10:00 a.m., 12:00 noon and 3:00 p.m. at four times of year, spring equinox (March 21st), summer solstice (June 21st), fall equinox (September 21st) and winter solstice (December. 21st). All times noted are Pacific Standard Time unless otherwise noted with Daylight Savings Time (DST). Four-story Analysis: The shadow study shows that with the four-story project, the most severe impact would be at 3:00 p.m. on December 21 (Figure 13.3) when the entire first floor, approximately half of the second floor (front portion) a quarter of the third floor (front portion) of 1435 Bellevue Avenue (to the east of project) would be shaded. It is estimated that six large windows, three small windows and one egress door would be located in this shaded area. December 21 is known as the winter solstice when the sun appears at its lowest point in the sky at this time of day and this time of year. Therefore, the shadow cast by the proposed four-story building will put the entire front section of 1435 Bellevue Avenue in shadow (to the east of the project). The adjacent property at to the east, 1435 Bellevue Avenue (to the east of the project) will also be affected by shadows on March 21 at 3:00 p.m. and September 21 at 4:00 p.m. (DST) (Figure 13.1) when a shadow will be cast on two-thirds of the first floor, covering two large windows and one small window. The second floor would be partially shaded, however there are no windows in this area. The shadow on March 21 at 3:00 p.m. and September 21 at 4:00 p.m. (DST) (Figure 13.1) would wrap around to the front of the building and would put a corner of the first floor and shade one and a half large windows on the front elevation. The study indicated that there would be no shadow impact on 1457 Bellevue Avenue (to the west of the project), which is located on the right side of the subject property. There would be no impact on 1435 Bellevue Avenue (to the east of the prof ect) at the following dates and times: at 10:00 a.m. and 12:00 p.m. on March 21 (Spring Solstice) and December 21 (Winter Solstice); at 11:00 a.m. and 1:00 p.m. (DST) on June 21 (Summer Solstice) and September 21(Fall Solstice); and at 4:00 p.m. on June 21 (Figure 13.2). The rear of this property is bordered by the C-1, Subarea B zone, which does not have residential uses. The property directly behind the proposed condominium building is currently an office building that contains no residences that would be affected by the shadow changes cast by the site.

The existing redwood tree near the creek is proposed to remain, however the cedar tree next to it will be removed. The redwood tree is depicted in the Pacific Gas & Electric Company (PG&E) Heliodon shadow simulations. The existing pittosporum trees near the location of the new bridge over Ralston Creek will remain. The majority of the existing trees located in front of the existing structures will be removed and replaced with new landscaping. There is an existing 16" Magnolia located to the right of the front building at 1445 Bellevue that will be removed and four 24" box size Yew Pines will be planted as replacement. However, the two liquid amber trees that are located within the City right-of-way will remain. Three-story Alternative: The shadow study for the three-story alternative, 35 foot tall building, (using the same building footprint, but a three-story structure) shows that as with the four story option the biggest shadow impact would be on December 21 at 3:00 p.m. (Figure 13.6). On December 21 at 10:00 a.m. and 12:00 p.m. a three story building would cast shadows on the right front corner of the building to the east, 1435 Bellevue Avenue. This shadow would increase and extend down to the right side of 1435 Bellevue (to the east of the project) by 3:00 p.m. on December 21 (Figure 13.6). There would be no shadow impact on the building to the left, 1435 Bellevue Avenue (to the east of the project), on March, June and September 21 at 10:00 a.m., 12:00 p.m. and 3:00 p.m.. On March and September 21 at 10:00 a.m., 12:00 p.m. and 3:00 p.m. (Figure 13.4) the building to the right of the proposed project, 1457 Bellevue Avenue (to the west of the project), would cast a shadow the first floor of the proposed building. Conclusion: When comparing the existing conditions with the proposed four story building the biggest impact on the adjacent properties will be at 3:00 p.m. on December 21 (Figure 13.3) when the entire first floor, approximately half of the second floor (front portion) a quarter of the third floor (front portion) of 1435 Bellevue Avenue (to the east of the project) would be shaded. However as stated above, December 21 is when the sun appears at its lowest point in the sky at this time of day and this time of year. Therefore, the shadow cast by the proposed four-story building will put the entire front section of 1435 Bellevue Avenue (to the east of the project) in shadow. Where currently with the existing building configuration the most shadow impact is also on December 21 at 10:00 a.m., 12:00 p.m. and 3:00 p.m. when 1441 Bellevue casts a shadow on the northeast corner of the building 1435 Bellevue Avenue (to the east of the project). At 3:00 p.m. this impact is most intense when the front building at 1441 Bellevue Avenue casts a shadow only on the first floor of the right side section of the building at 1435 Bellevue (to the east of the project). Currently on March 21 or September 21 there is no shadow impact from the existing structures at 1441 and 1445 Bellevue on 1435 (to the east of the project) or 1457 Bellevue (to the west of the project). With the new four-story building proposed 1435 Bellevue Avenue (to the east of the project) will be affected by shadows on March 21 at 3:00 p.m. and September 21 at 4:00 p.m. (DST) (Figure 13.1) when a shadow will be cast on two-thirds of the first floor, covering two large windows and one small window. The second floor would be partially shaded, however there are no windows in this area. The shadow on March 21 at 3:00 p.m. and September 21 at 4:00 p.m. (DST) (Figure 13.1) would wrap around to the front of the building and would put a corner of the first floor and shade one and a half large windows on the front elevation. 37 I 1 , ,h 3 ST'4iYRV ll7 UOLDII "dG MARCH 2 flit, 3pm SE li"`tl'fEflMBE R 21st, 4p m (DST) FIGURE 13.4 1435 1457 TOM u �,d Y MY 1�8�r6``��'��41h"�PYi I 9 � � t it =Y } J h I • ! � 1 f 1 I�d Y i' ��� �1 4 '"�� I'_"] � I � I I _ � h ,�µ � I 4 I Y , r-.-i 1 l II II l t r � I rl � ; �. �'mnti� r rw ,vi x" yy rye vp r , 3 STORY BUILDING FIGURE 13.5 mWW 3 STORY BUILDING DECEMBER 21st, 3pm FIGURE 13.6 Initial Study Summary 1441-1445 Bellevue Avenue Burlingame has not established a community standard for shadow impacts, and most jurisdictions do not have such criteria for significance. The following considerations are often used to judge the significance of shadow impacts in environmental documents. a. Would the shadow substantially affect the use of public open space or publicly accessible private open space? This can be examined using net new shadow on public open space during mid -day hours. b. Would the shadow substantially affect other public areas, such as sidewalks with high pedestrian volumes? Those effects are usually judged to have a high threshold of significance because sidewalks are more transient in use and activity. c. New shadow on private property, such as side yards, back yards, patios, decks, windows, skylights, and similar areas are not considered significant effects, since it would not affect large numbers of people or a public amenity. When new shadows are created on such private areas by development that is consistent with the applicable zoning controls for setback, height and building mass, it is considered to be typical conditions that can arise in a developed urban area, and not considered to be a significant adverse impact on the environment. Although both the three and four story alternatives would cast shadows on the property to the right, 1435 Bellevue Avenue (to the east of the project), on December 21 at 3 :00 p.m. (Figure 13.3) it is not considered a significant effect because it is not affecting large numbers of people (18 units at 1435 Bellevue Avenue) or a public amenity. Also on December 21 the sun is positioned at its lowest point in the sky, therefore creating longer shadows than during other days and months. This date and time would result in the most shadow impact with the entire first floor shaded, approximately half of the second floor and a quarter of the third floor shaded with the four story alternative. Where the three story alternative on December 21 at 3:00 p.m. (Figure 13.6) three quarters of the first floor, and approximately a third of the second floor would be shaded. Based on these established criteria, the proposed four story building, as well as the three story alternative, would not be considered to have significant shadow impacts. Exterior lighting provided for the project will be required to conform to the City's Illumination Ordinance (1477), which requires all illumination to be directed onto the site. Mitigation: • that this project shall comply with Ordinance No. 1477, Exterior Illumination Ordinance. 14. CULTURAL RESOURCES SUMMARY: When this project was initially reviewed there was concern that 1445 Bellevue Avenue was the former location of the American Red Cross during World War II. However after further research it was discovered that the Red Cross was actually located at 1449 Bellevue Avenue, which is now known as 1457 Bellevue Avenue. The structure formerly occupied by the Red Cross was demolished in late 1982 or early 1983 to make way for the existing 18-unit condominium building that was approved for construction by the Planning Commission on November 8, 1982. The two properties, 1441 and 1445 Bellevue Avenue, involved in this project have been developed in residential uses for many years prior to this proposal. No local information has been found which would suggest that either of the existing buildings have any local significance. As a result, these structures do not appear to be eligible for listing in the California Register of Historic Resources or the National Register of Historic Places. As such, the structures are not considered to be an historic resource as defined Initial Study Summary 1441-1445 Bellevue Avenue in Section 21084.1 of the California Environmental Quality Act. Any archeological or historic, cultural, or ethnic sites, which may have been in or near the locations, were disturbed or destroyed by previous development prior to this proposal. Should any cultural resources be discovered during construction, work will be halted until they are fully investigated. Mitigation: • 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. 15. 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 sites involved in this project are not presently zoned or used for recreational uses. The site as it is currently developed contains five structures, one of which is located at the rear of the property which is access via a wooden pedestrian bridge that straddles Ralston Creek. As part of this proposal the multiple family structure will be removed and the approximately 5,000 SF area on the other side of the creek will be developed as common usable open space for use of the residents on site. There will be a paved courtyard area with foundation in the center, along with pergola at each end of the courtyard. This open space area will also contain an outdoor fireplace, a barbeque and outdoor furniture. The surrounding area will be fully landscaped. Therefore this proposal will result in a new recreational opportunity on -site for residents of the condominium building proposed with this project.
