C IT Y OF ALO ALT Agenda Date: To: From: Subject: March 7,2013 Architectural Review Board Elena Lee, Senior Planner 1 Architectural Review Board Staff Report Department: Planning and Community Environment 210-216 Bryant St. [12PLN-00493]: Request by Young and Borlik Architects, on behalf of Real Estate Management Associates, for Architectural Review of a 370 sq. ft. second floor addition and fa<;ade improvements, including a Design Enhancement Exception to allow an encroachment into the side yard daylight plane, to an existing four unit multi-family building. Environmental Assessment: Exempt from the provisions of CEQ A, 15301 (Existing Facilities). RECOMMENDATION Staff recommends the Architectural Review Board (ARB) recommend approval of the proposed project based upon the findings contained in Attachment A and conditions of approval contained in Attachment B. BACKGROUND The 5,300 sq. ft. site is located in the Multi-family residential RM-30 zoning district. The property is currently developed with a two-story, four unit apartment building with an attached four car garage that is accessed from a 13 -foot wide alley at the rear of the site. Four uncovered parking spaces are provided in front of the garage. The building's first and second floors each have one one-bedroom unit and one two-bedroom unit. The 2,714 sq. ft. four-unit building is considered a legal non-confoffiling facility due to its small front yard setback and extra density. The existing first floor encroaches ten feet into the required 20 foot front setback. Based on the maximum density for the current RM-30 zoning designation, a total of three units would now be allowed. The property is bounded by Bryant Street to the northeast, two-unit residential buildings to the nOl1hwest and the southeast, and an alley to the southwest. The properties located across Bryant Street and on the other side of the alley are single family homes and multi-family residential developments. The building is less than 50 years old and is not considered historic. 12PLN-00493 Page 1 of3 PROJECT DESCRIPTION The applicant is proposing to add approximately 370 sq. ft. to the second floor and remodel the building. The addition is proposed at the front of the building, above the existing first floor. The addition will set back more than twenty feet from the front property line, six feet from the side property lines and ten feet from the rear property line, in compliance with current development standards. This addition would enable the second story 'unit at the front of the building to be reconfigured to accommodate a new master bathroom, a larger living room and a private balcony. The applicant also proposes to remove a partially open stairwell in the garage. The first floor area formerly occupied by the stairwell would be converted to storage, while the second floor space would enable a slight increase to the rear unit with the creation of a study and a new 55 sq. ft. private balcony. There are no significant changes proposed for the configuration of the two first floor units, other than the relocation of doorways, reorientation of the bathroom, and addition of a laundry area. The project also includes minor changes to the stairs and landings for the first floor unit and a new wood fence. "{he applicant proposes some fa9ade changes, with the greatest change being the windows. The majority of windows would be replaced with sliders with divided lights. On the front elevation, the size of two existing windows on the first floor would be reduced. The window on the right would be made smaller to accommodate the kitchen sink below. The second floor front elevation would receive two new windows and a sliding glass door, leading to the new balcony. On the right side elevation, two existing first floor windows in the center would be replaced with new sliders of the same size, one door would be removed, and the window closest to the street would be replaced with a sliding glass door. The first floor unit's stairway/landing is being shifted towards the interior for the new sliding glass door. The windows on the second floor are being retained and resized. The window towards the rear is being relocated and enlarged, with the window nearest to the street being enlarged. The sliding glass door would now lead to a private balcony instead of the stairwell. On the rear elevation, the sliding glass door that currently leads to the stairwell to be removed is deleted. One of the three windows is also proposed to be removed. Along the left side elevation, the applicant is proposing to replace the two windows on the first floor, and reduce the size of the right side bathroom window. The new rear balcony can be seen at the top left comer. The second floor addition can be seen toward the front of the building, including a new hipped roof dormer element that is part of the redesigned living room and the new balcony to the right. A window would be added to the far left on the second floor for the kitchen. The second floor would keep two windows on either side of the entry, both slightly smaller than the original. Staff has included a condition requiring that all windows be converted to sliders to retain consistency across the entire building. Staff has also included another condition requiring the applicant to modify the proportion of the window located to the right on the first floor of the front elevation, so it is more consistent with the other windows on the same elevation. New composition shingle roof would be installed and stucco wall treatment would be included, to match the existing building. 12PLN-00493 Page 2 of3 DISCUSSION Zoning Compliance As discussed above, the subject building is legal non-conforming in terms of density and setbacks. The addition would be consistent with the current development standards of the RM-30 zoning designation for floor area maximums and setbacks. No additional bedrooms are proposed that would trigger the requirement for additional parking. However, as discussed below, the applicant is requesting a Design Enhancement Exception . (DEE) to encroach into the side yard daylight plane along the right side property line. Design Enhancement Encroachment The applicant is requesting a DEE to allow an approximately 13-foot portion of the new second floor addition to encroach approximately four feet into the side yard daylight plane. Chapter 18.13.040 of the Palo Alto Municipal Code (PAMC) establishes a daylight plane requirement along the side and rear of the property. The applicant is requesting the exception because of site constraints, including the large oak tree, and because the proposed alignment allows the addition to maintain the existing wall and roof eave lines of the building. As set forth in Attachment A, the required findings can be made for the proposed exceptions. The granting of the DEE would assist in the retention and enhancement of four existing residential rental units. ENVIRONMENTAL REVIEW The project would be an alteration to an existing facility and new construction not exceeding 10,000 square feet, qualifying for a Class 3 Categorical exemption per section 15301 of the California Environmental Quality Act.

(1) The project is consistent and compatible with applicable elements of the city's Comprehensive Plan in that the site has a Comprehensive Plan Land Use Designation of Multi-Family Residential and the use is consistent with the designation as a residential building. The project is consistent with Policy L-12 in that the project would preserve the character of the residential neighborhoods with a.design that is compatible with the neighborhood and existing structures. (2) The design is compatible with the immediate environment of the site in that the project would retain the scale and architectural character of the area. The proposal is for a small addition that is being kept within the existing footprint of the building and the same height. The surrounding buildings are of similar size and scale. (3) The design is appropriate to the function of the project in that the addition, open space and other building improvements would enhance building as a residence and the overall neighborhood. (5) The design promotes harmonious transitions in scale and character between different designated land uses. The project provides sufficient setbacks and substantially similar building heights to maintain an appropriate transition in scale and character between this use and adjacent properties. (7) The planning and siting of the addition and other related improvements on the site create an internal sense of order and provide a desirable environment for residents, visitors and the general community, in that the addition makes good use of available space on this narrow lot by building above existing first floor. (8) The amount and arrangement of open space are appropriate to the design and function of the structures because it provides additional private open space while retaining a landscaped setback from the site's perimeters. (9) Sufficient ancillary functions are provided to support the main functions of the project in that the proposal includes sufficient parking and areas to accommodate the trash and recycling needs of the development. The addition is minor that would not increase demand for ancillary functions. (10) Access to the property and circulation thereon are safe and convenient for pedestrians, cyclists and vehicles in that the existing walkways, parking spaces and driveways are being retained. . (11) Natural features are appropriately preserved and integrated with the project, in that the existing mature redwood tree is being retained and protected. (12) The materials, textures, colors and details of construction and plant nlaterial are appropriate expression to the design and function of the site because they will be compatible to the existing building and architectural style. (13) The landscape design concept for the site, as shown by the relationship of plant masses, open space, scale, plant forms and foliage textures and colors create a desirable and functional environment in that the majority of landscaping, including a nlature redwood tree, are being retained on site. (14) Plant material is suitable and adaptable to the site, capable of being properly maintained on the site, and is of a variety that would tend to be drought-resistant and to reduce consumption of water in its installation and maintenance. (15) The design is energy efficient and incorporates renewable energy design elements, including the replacement of single pane windows with more energy efficient dual pane windows. (16) The design is consistent and compatible with the purpose of architectural review as set forth above. Findings 4 and 6 are not applicable to this project. ATTACHMENT A DRAFT DESIGN ENHANCEMENT EXCEPTIONS FINDING 210-216 Bryant St.lFile No. 12PLN-00493 The reque-sted-I)esign-Enhanee-ment-Exeeptions ED EEs) are eonsistent-with the findings as stated in Palo Alto Munidpal Code (PAMC) Chapter 18.76.050 (e). The Design Enhaneement Exeeption is being requested to allow four foot maximum eneroaehment into the side yard daylight plane. 1. There are exceptional or extraordinary circumstances or conditions applicable to the property or site improvements involved that do not apply generally to property in the same zone district, in that: The 50 x 106 foot site is uniquely eonstrained in that it is a very narrow lot and is an already developed site. The property is also eonstrained by a 40.5" diameter proteeted redwood tree. 2. The granting of these Exceptions will enhance the appearance of the site or structure, or improve the neighborhood character of the project and preserve an existing or proposed architectural style in a manner which would not otherwise be accomplished through strict application of the minimum requirements of Title 18 and the standards for review set forth in this Chapter, in that: Granting the DEE to allow eneroaehment into the side yard daylight plane would allow the preservation of a mature redwood tree on the west side of the property. It would also allow the addition to be in plaeed above the existing first floor and where the existing wall and eave lines ean be preserved. 3. The Exception is related to a site improvement that will not be detrimental or injurious to property or improvement in the site vicinity, and will not be detrimental to the public health, safety, general welfare or convenience, in that: The requested DEEs will not be detrimental or injurious to property or improvement in the site vidnity as the exeeption is very minor in seope. The addition would be plaeed above the existing first floor and would retain the existing side yard setbaek. The DEE would allow the existing building design to be maintained, while allowing an aging building to be updated and beeome more funetional. ATTACHMENT A CONTEXT-BASED DESIGN CONSIDERATIONSIFINDINGS 210-216 Bryant St.l12PLN-00493 PUrsuant-to-PAM C18.1l.060(b), in addition to the-findings for Architectural·Review . contained in PAMC 18.76.020(d) 'Multiple Family Context-Based Design Criteria,' the following additional findings have been made in the affirmative: 1. Massing· and Building Facades: Massing and building facades shall be designed to create a residential scale in keeping with Palo Alto neighborhoods, and to provide a relationship with streets. The project is a snlall addition that nlaintains the existing design and scale of the building. It is sinlilar in size and scale to the other residential buildings in the neighborhood. The street facing fayade is proposed to be improved with more windows. 2. Low-Density Residential Transitions: Where new projects are built abutting existing lower-scale residential development, care shall be taken to respect the scale and privacy of neighboring properties. The proposed addition is small in scope and would not increase the number of units. It is similar in size to other neighborhood buildings. The new balconies are placed towards the front and rear, respecting the privacy of the adjacent properties. 3. Project Open Space: Private and public open space shall be provided so that it is usable for the residents and visitors of the site. The proposed addition is small in scope but includes two new balconies for additional private open space. The addition is proposed above the first floor, which would allow existing common open space to be retained. 4. Parking Design: Parking shall be accommodated but shall not be allowed to overwhelm the character of the project or detract from the pedestrian environment. The existing garage at the rear of the property is being retained. So the garage will not detract from the pedestrian environment along the street. 5. Large (multi-acre) Sites. Large (in excess of one acre) sites shall be designed so that street, block, and building patterns are consistent with those of the surrounding neighborhood. This finding is not applicable to this project since the site is approximately 5,300 square feet in area. 6. Housing Variety and Units on Individual Lots: Multi-family projects may include a variety of unit types such as small-lot detached units, attached rowhousesltownhouses, and cottage clusters in order to achieve variety and create transitions to adjacent existing development. The project proposes the retention of an existing four unit residential complex, which contributes to the existing variety of residences in this multi-family neighborhood. 7. Sustainability and Green Building Design. Project design and materials to achieve sustainability and green building design shall be incorporated into the project. The project will be required to comply with the City's Green Building Ordinance. Specifically, the applicant proposes to replace existing single pane windows with more energy efficient dual pane windows.

YOUNG AND BORLIK ARCHITECTS, INCORPORATED Attachment C 480 LYTTON AVENUE SUITE 8 PALO ALTO, CA 94301 TELEPHONE (650) 688-1950 FAX (650) 323-1112 Amy French, Planning Manager Planning Division City of Palo Alto 285 Hamilton Ave. Palo Alto, CA 94301 Re: Project Description Letter for ARB Submittal Design Enhancement Exception findings Remodel and addition to 210-216 Bryant St. Dear Ms. French, WEB www.ybarchitects.com November 27, 2012 Departrl !c,rll (Yi ;'I;::'"!I .\[ig & Community E.nvironrnent This letter is to serve as the project description letter for the proposed improvement to the four-unit apartment building at the above address. The property is zoned for RM-30 multi-family development, is 5,300 sf in size at approximately 50 feet wide and 106 feet deep, considered substandard per the current zoning standards. It is currently developed with an existing two-story apartment building with four units. Two of the apartments are two­ bedroom units and the other two are one-bedroom units. Based on lot size, the permitted density in the current zoning of up to 30 units per acre would allow only three units where four exist. The total floor area of all the units is 2,714 sf, where 3,180 sf is allowed. The existing structural coverage is 2,272 sf where 2,210 sf is allowed. There are currently 8 parking spaces on site (four covered and four· uncovered). Based on the existing number of bedrooms, the current zoning would require four covered parking spaces and three uncovered parking spaces .. Plans of the existing apartment building are found on the City's microfilm records, and built to the standards in affect at that time (1960's). The proposed project would add approximately 370. sf to the second floor of the building. No additional bedrooms would be added in this design. The interior of Apartment 214 upstairs would be remodeled throughout with an addition at the front side to increase the size of the unit. This added floor area and the window relocations would accommodate a new second bathroom and increase the living room space. A shallow bay window added facing the interior side adds some definition.to break up the length of that elevation. The addition of a new covered outdoor balcony would also add private outdoor space, where none existed before. The interior of Apartment 216 upstairs would also be remodeled throughout, with associated window relocations per the new plan. There would be a small increase in size of the unit from the inclusion of a portion of the existing rear stairwell, which all sits below the existing roof structure. The remaining portion of the stairwell would be converted to an outdoor balcony for private open space. The interior of Apartment 212 downstairs would be remodeled, with associated window relocations per the new plan, but with no increase in size. Theinterior of Apartment 214 downstairs would remain the same, with only window replacements at the existing locations to match the rest of the building, and with no increase in size. Minor interior wall modifications would allow an interior laundry machine closet. The total proposed square footage of the building would be 3,084 sf, within the allowable 3,180 sf. limit. Re: ARB submittal for 210 -216 Bryant There would be no increase in the number of apartment units, with regards to the existing non-conforming density on the lot. There would be no change to the number of bedrooms, or triggered changes to the required parking spaces, with regards to the existing non-conforming parking space size and back up distances. There would be no change to the existing structural building coverage. The second floor addition would conform to the required front yard setback of 20 feet, but there would be no change to the existing non-conforming front setback of 10 feet of the fIrst floor below, The addition would conform to the side yard setback of 6 feet, as does the rest of the structure. We have improved the conditions related to outdoor space on the lot, even though there have been no changes to the number of bedrooms to affect the requirement. The only change would be an addition in floor area that would still leave the project within the allowable limit. The new portions of the building would be constructed to match the existing, with composition roofing and stucco exterior siding. New windows throughout would replace the existing single pane windows. An existing large heritage redwood tree that sits about mid depth on the lot would remain and be protected throughout construction. Also as part of this project we ask for a Design Enhancement Exception with regards to a 13 foot section of the proposed second floor addition that would encroach into the required side yard daylight plane. The existing second floor is about 51 feet in length, and stacks on top of the first floor below. Under current zoning standards that portion of the existing structure' encroaches into the required daylight plane. The proposed addition in this project would align and blend with the existing second floor, which would maintain the regular eave line and proportions of the existing structure. We feel keeping the alignment of the second floor wall and eave line would maintain the architectural style, which is very balanced and regular. Conforming with the daylight plane for this short section would push the wall line over about 4 feet, and introduce offsets which would make the front elevation off-balanced not consistent with the original architecture. Based on the text in 18.76.050, the purpose of the Design Enhancement Exception (D.E.E.) is to 1) enhance the proposed project without altering the function or use of the site or impact on surrounding properties and 2) enable the preservation of the architectural style of the existing improvements on site. As part of this proposal, the use, function, number of units, etc. would remain consistent with the existing conditions, and considering that 51 feet of the second floor has existed in this configuration for the entire life of the building, this small extension would not change the relationship or impact on the adjacent properties. Additionally, the regular nature of the architecture would be preserved by maintaining the existing wall and eave line, rather that introducing offset wall lines that would add eccentricities and change the balance of the elevation from the street. The exterior wall line of the addition as proposed also makes allowance for a new balcony to provide private outdoor space for this apartment, which does not currently exist, and would not meet the minimum size and dimensions if the addition were shifted for the daylight plane. The granting of this exception to the daylight plane only would not result in a floor area that exceeds the allowable limit. There would be no impact on the existing parking, with no reductions or triggered increases in the required number of spaces. Since the additional area will be added to the second floor, there will not be a decrease in the open space or landscaped area on the site. With regard to the required findings of a D.E.E.: 1. The lot is constrained by the existing location of the structure on the site and by the dominance of the large redwood tree that sits adjacent to it on this narrow lot. There would be no options to add floor area onthe first floor that would conform to the current zoning setbacks yet not have pg.2 Re: ARB submittal for 210 -216 Bryant significant impacts on the tree root zone or necessitate its removal to achieve the same size addition. These existing physical features are unique to this property and are unlike any others in its immediate area. 2. The approval of this exception for this minor encroachment into the daylight plane would allow the regular geometry of the architecture would be preserved, by maintaining the existing wall lines and roof eave lines of the original architecture. A strict application of the daylight plane per the current zoning would force a shift to the second floor that would set the walls and roof line of the second floor off center above the first floor walls and roof below . 3. The exception to the daylight plane at this short section of the addition would be a minor 13 foot extension of the existing 51 foot second floor wing of the structure. Related to the adjacent neighbor, an existing mature coast live oak would screen the portion of the addition, and there would be no windows at the addition to overlook that side. The minor portion of addition would not be detrimental to the vicinity, and it would be hard to perceive it as detrimental to the public health, safety, welfare, or convenience.

Zone: RP. Environmental Assessment: Categorically exempt from California Environmental Quality Act (CEQA) requirements. RECOMMENDATION Staff reconunends the Architectural Review Board (ARB) conduct a preliminary review of the proposed project and provide conlments on the proposed design to staff and the applicant. No formal action may be taken at a preliminary review; comments nlade at a preliminary review are not binding on the City or the applicant. Staff has summarized key issues to provide a framework for comments. BACKGROUND Site Information The 4.57 acre project site is located on the west comer of the intersection of Hanover Street and Page Mill Road within the Stanford Research Park. The project site is currently laid out as two independent parcels, each having one two-story office building and at-grade parking. The L-shaped project site has the Stanford Channel dividing the comer portion of the site from the deeper and narrower interior portion. The total floor area of the existing buildings is 86,925 square feet (sf) and is currently occupied by Mercedes Benz and Robotex. The project site is surrounded by existing Research and Development uses, with the exception of the Mayfield Fire Station that is across Hanover Street. The parcel (1082 California Avenue) that backs up to the project site, along with two others, will be developed as a housing site by Stanford in accordance with the Mayfield Agreement to construct 180 market rate units. Project Description The proposed project includes demolition of the existing two commercial buildings and rebuilding of one two-story building containing the same amount of floor area (86,925 sf). The new structure would also include a below grade garage providing 121 spaces, bike storage and showers. The proposal shows the new office building located on the comer portion of the lot and the surface parking located on the interior portion of the lot; the Stanford Channel separates the new building from the parking lot. The parking lot will be landscaped and planted with numerous trees, and will include photo voltaic (PV) solar panel canopies to function as additional shade cover, in addition to producing clean energy for the site. The design of the building creates a center courtyard that provides the primary circulation connection between the building and the adjacent surface parking lot, as seen in Figure 1 below. In addition to a pedestrian bridge, a vehicle bridge is proposed over the channel providing a secondary vehicle access to the site. The conceptual plan includes the planting of new trees, drought tolerant landscape materials, and bio-swales for storm water retention in the parking lot. The proposed design includes a masonry base with metal and glass elevations with deep set windows. The materials proposed are warm toned glass fiber reinforced concrete (GFRC), Champagne Bronze metal skin, spandrels and metal sunshades, and the use of clear glass, glass sunshades and fritted clear glass around the elevations. The applicant intends to exceed the Cal Green Tier 2 standards, with a LEED Platinum project and significant on-site production of electricity with the use ofPV panels. Additional information has been provided by the applicant for reference in Attachment A. In the applicant's Project Narrative (Attachment A) reference is made to a request for a Design Enhancement Exception (DEE) for the use ofPV panels to meet the parking lot shade requirement, instead of trees, and staff determined that an exception was not needed to utilize structures in order to meet this parking lot shading requirements. ••••••••••• ~ •• : •• ::::.::.:.::.: ::.:.'.-:,-..:::.":':.:.:.::.;:.... • •••••••••••••••••.••••••••••••••••••••••• ""!; , I i ···········~r~~~for~·Jr -" Trash Enclo ure -" ·······;)_. ___ ._r- Hanover Street Figure 1: Conceptual Site Plan 1400 Page Mill Road [13PLN-00003] I Page 2 DISCUSSION Zoning Compliance The proposed conceptual plan appears to be in general compliance with the Zoning Code with the exception of one structure. One of the proposed PV canopies is located within the 20 foot side setback (See "A" in Figure 1), and the RP zone district does not allow for accessory structures to encroach into the setback. An alternative approach to this placement is to locate the PV canopies in the areas identified as "B" and or "C" in Figure 1 above. Floor Area Ratio The proposed project intends to utilize the same amount of floor area that currently exists today for the two commercial buildings. This floor area exceeds what would be permitted to be constructed today, but is allowed, based upon PAMC 18.70.100(c): "A noncomplying facility in the commercial CS, CN and CC zones and the industrial MOR, ROLM, RP and OM districts, except for those areas designated as special study areas, existing on August 1, 1989, which when built was a complying facility, shall be permitted to be remodeled, improved or replaced in accordance with applicable site development regulations other than floor area ratio, provided that any such remodeling, improvement or replacement shall not result in increased floor area." Parking Lot Design The parking lot will need to comply with the requirements of P AMC code section 18.54 for the parking lot design. With the information that has been provided in the conceptual plans, the parking lot appears to be deficient in the number of landscaped islands provided (one for every ten spaces in a single row). All projects requiring discretionary review within a commercially zoned property should, where feasible, include the following: • Incorporation of recycled water usage into the design of landscape and irrigation systems; • Consideration of plants suitable for irrigation with recycled water; • The installation of the infrastructure necessary to connect the irrigation system to the City's recycled water supply, if available in the foreseeable future. Performance Criteria The project is subject to meeting the Performance Criteria found in Palo Alto Municipal Code (P AMC) Section 18.23. These criteria are intended to provide additional standards to be used in the design and evaluation of developments in multi-family, commercial and industrial zones. The criteria are intended to make new developments and major architectural review projects compatible with nearby residential and business areas and to enhance the desirability of the proposed developments. There are nine specific design elements that are applicable to approval of RP zoned projects, in addition to the required ARB findings. For this project, the Performance Criteria are applicable to the rear portion of the surface parking lot that backs up to the future residential development associated with the Mayfield Agreement. The four design elements applicable to this particular project include: (1) Lighting, (2) Visual, Screening and Landscaping, (3) Parking, and (4) Vehicular, Pedestrian, and Bicycle Site Access. Attachment B provides the complete list of Performance Criteria for reference. 1400 Page [13PLN-00003] Page 3 DEPARTMENTAL REVIEW City department written comments are included in Attachment C. The comments provided at this stage of the project are relatively typical of commercial development. One specific comment was received from the Solid Waste Group that requires the trash enclosure, along the drive aisle near the garage entrance, to be enlarged. ENVIRONMENTAL REVIEW No environmental review is required for this Preliminary Review application, as it is not considered a project under the California Environmental Quality Act (CEQA). An Environmental Assessment will be prepared for the review with the formal application.

The site, at the southwest corner of Page Mill Road and Hanover Street, is a prominent gateway location within the Stanford Research Park. The site is approximately 4.6 acres and carries the Research Park (RP) zoning designation. It currently contains two 2-story office buildings and surface parking. The existing building at 1400 Page Mill Road is currently occupied by two tenants, Mercedes Benz and Robotex. The other existing building on the project site is 2670-2680-2690 Hanover Street, which is currently occupied by Stanford Hospitals and Clinics. The proposed new 86,925 square foot building will contain the same total floor area as the two existing buildings together. The proposed single-building design allows for a more efficient use of the site and substantially more landscaped area than exists on the site currently. The building will be two stories above grade with a single level subterranean parking garage. The entrance to the parking garage will be along a secondary entry drive from Hanover Street. The main entry to the property will be from Page Mill Road. The building will utilize high-quality materials, high performance design parameters, and an extremely energy efficient envelope. As a result, it will present an outstanding example for future buildings within the Park. The project will significantly exceed the required CAL Green Tier 2 standards, with objectives of LEED Platinum certification and a substantial portion of electricity produced onsite with photovoltaic panels. The building will provide excellent indoor air quality, abundant natural daylighting without glare, and excellent thermal comfort for occupants. Each elevation of the proposed building is designed and engineered based on solar aspect to minimize solar heat gain and solar glare on the interior spaces. Horizontal and vertical architectural sunshades are used in multiple compositions to respond to the specific solar orientation of each fac;ade. This advanced design philosophy will create a building that will be a high performance, energy efficient workplace with substantially reduced energy consumption and increased occupant comfort, compared to current standard Class A office designs. The site slopes down towards the north from approximately 50' at the highest point along the southern boundary to approximately 42' at Hanover Street. There is an existing exposed Santa Clara Valley Water District drainage channel traversing the site west to east that must remain in place. The new building will be adjacent to the Water District easement, and set back 50' from both the Page Mill and Hanover right of ways.

We propose to cover a portion of the surface parking with canopies of photovoltaic panels for shade and clean power generation. The project is requesting a Design Enhancement Exception (DEE) for the use of photovoltaic canopies over a portion of the surface parking in lieu of parking lot trees. These PV panels are essential to provide clean electrical power for the building, while also providing shade for cars within that portion of the parking lot. In the portion of the surface parking field nearest Page Mill, the project would include a grove of trees planted in excess of the density required by code. This will provide a more heavily landscaped appearance from the street and will minimize the visibility of the solar panels from Page Mill. The primary entry to the site will be from Page Mill Road. The entry drive and visitor parking area will be within the grove of trees described above, which marks a transition from busy Page Mill Road to the calm landscaped setting of the proposed new building. From the entry parking area there will be filtered views of the prominent lobby within the central courtyard. The courtyard will be a landscaped gathering space that embodies the "working in the garden" theme that has been the design guidepost for this building. This courtyard is temporal in its function as it provides both building access and gathering spaces for people throughout the day. The landscape design proposes to use a palate of drought tolerant and California adapted plants that will decrease water consumption and decrease use of harsh landscape chemicals. Storm water retention areas are incorporated into the landscape design as visual and aesthetic features to illustrate the sustainable connection between our local climate, plant communities and the cycle of water through ecosystems. The landscape design seeks to capture themes we see in the local environment such as grasslands, woodlands, and flowering plants that are attractive to native butterRies and birds. We look forward to feedback from the Architectural Review Board and the City of Palo Alto on this proposed redevelopment project.

Site Forces: Drainage Channel, Slope and Parcel Configuration 4 One significant site force is the fixed drainage channel and its easement that runs east -west through the entire site, and must remain relatively untouched. Besides width and length constraints, it also dictates height parameters since it is part of a larger drainage system. The drainage channel lies within an easement held by the Santa Clara Valley Water District and drainage requirements preclude placing a building on or over the drainage channel. The natural grade of the site begins at a low point on Hanover Street and slopes upward to a high point as you drive south up Page Mill Road toward Highway 280. The developable parcels are configured in an "L" shape with a long and narrow portion of the site located south of the drainage channel. The long and narrow portion of the site is poorly suited for large office buildings or parking garages/structures due to the narrow width dimension. This combination of forces led to the proposed configuration of surface parking and photovoltaic arrays to the south of the channel, and the two-story building with one level of under-building parking to the north. ·.;/.~.~:f~ ,,.:.·.·l: ..

Taken together they surround the building so that one's experience is working in a garden. The architecture is informed by the surroundings and the unique conditions facing each building fa~de. Hanover Street is quiet and unassuming, whereas Page Mill Road is busy and prominent. The south side of the building is sunny and private affording unique main entry solutions. The west side of the building is narrow with a garage entry and service area. Each elevation is tuned to its unique solar conditions as well, which vary dramatically at each point on the compass. 5 Following is a description of how key elements have been designed to respond to their place on the site: r-'-'---' __ ·_v·_·~·· ____ • ~~"~'1 I Tr.nl'ormar--~I Tralh encloture I I j Hanover Str.et Highlighting the Hanover Page Mill Corner -: I i 'i I I ~ !

At the intersection one sees that the north (on Hanover Street) is completely unshaded and very glassy. By contrast, the east elevation is a composition of horizontal and vertical sunshades because that is what is needed to address solar gain from morning sun. The vertical fins and their spandrel backdrop on the east elevation are glass rather than metal, and are designed to catch the morning light to make the vertical fins glow and sparkle. This creates a symbolic distinction between the east elevation of gentle morning light, and the south and west elevations where the mid-day and afternoon sun is stronger and more intense. Materials: As one moves from the Hanover -Page Mill corner up Page Mill to the entry drive, one is first exposed to the building's basic materials and organization of parts. The building is a metal and glass composition, with a masonry base that appears to "lay" up against the lighter building creating deep set windows, and anchoring the structure to the ground. Masonry: Warm toned GFRC Metal Skin, Spandrel & Metal Sunshades: Champagne Bronze Glass: Clear Glass Sunshades: Translucent clear glass Glass Spandrel: Fritted clear glass It should be noted that a wonderful dynamic quality of the Champagne Bronze metal material is the way it changes tone depending on how light hits it.

The Grove & Introduction to the Photovoltaic Arrays: Building users enter the site into "The Grove," a heavily landscaped parking court that allows for passenger drop off, and employee and visitor parking under a canopy of trees. To the west past The Grove, one sees a photovoltaic array over the back parking area that is a key element in the energy story of the project. The Grove screens the PV array from the street, maintaining the green open landscape feeling of the Research Park for those passing by. Entry sequence: One experiences trees, then entry courtyard, then photovoitaics beyond. South Facing Entry Garden: From The Grove you see the building lobby located within a courtyard garden.

The garden is made up of several zones. After crossing the bridge you enter a bosque of trees. The parking garage below the building was held back so that they can be planted in 9 full depth soil. Beyond that, much of the garden is on podium and utilizes small plaza trees or shrubs, benches, bike racks and low planting beds. The space is both the way to get to the lobby, and a large, social interactive and collaborative people space. Given that people enjoy sunlight, the southern orientation will set it up to be a desirable place to be. Shade is provided primarily by the bosque of trees, and we anticipate umbrellas over seating areas .. North Facing Hanover Garden: The building geometry captures a garden the same width, but shallower depth, on the north Hanover side of the building. Because of the grades dictated by the drainage channel, that particular garden is several feet above Hanover Street, and +/-50' back from the street. This garden will have a more quiet character, and will allow users to take advantage of the peacefulness and cool shaded temperatures offered on the north side of the building in summer. Service & Entry to the Below Grade Parking Structure: On the west side of the building and around the corner from the main entry is the garage entry and service area, with direct access from a Hanover Street driveway. A building of this sort has little truck traffic, however there is a need to accommodate Fed-Ex and day-to-day deliveries. Taking advantage of the natural grades a small area is created where trucks may park behind a landscape screen. Incorporated into the same area are trash enclosure and transformer.

GOAL 2: Highly Energy Efficient and Onsite Solar Energy 10 The project's sustainability goal is ambitious. It is being designed to use far less electricity than conventional buildings, and then generate the majority or all of the electricity it needs from onsite solar panels. The bar is high and per standardized measurement methods, the actual success will not be validated until the building has been in operation for a year. In addition, an important goal of the ownership is to demonstrate that buildings can achieve a very high level of sustainability within the economics of today's rent rates. This comes from the fact that they have occupied this site for the past 50+ years, and feel they want to help advance the state of the art by showing that you can offer sustainability and comfort in a building of lasting quality. The strategy to achieve this goal is to make the buildings themselves as energy efficient as possible through integrated design. By controlling the amount of glass, and carefully shading each exposure for optimum efficiency the design team has drastically reduced the amount of energy the building needs. Triple glazing and thermally detached skin help make the envelope energy efficient. Shading is a combination of building elements as well as glass and metal sunshades -each optimally tuned for their particular exposure. The depth and placement of shades is therefore different of each exposure. Once we have the building using as little energy as possible, we provide much of that energy through a photovoltaic array that extends across the building's roofs, and on shade structures over the back parking area. Solar power will offset the building's electricity needs for cooling, lighting, and plug loads. A natural gas boiler will be used to provide heat in winter, comprising 15-20% of the building's total energy consumption. Note that to accommodate this we are asking for a DEE to replace some of the required parking lot trees with a photovoltaic array.

This is because the building needs to limit direct sun penetration (smaller windows), and take control of the amount of lighting and cooling. This project is designed to tackle that conundrum through its shading strategy which controls direct sunlight penetration as well as glare. The interior will be light and airy and comfortable because direct glare and solar gain (heat) will be minimized during the hot summer months. The highly energy efficient shell of the building, combined with reduced glare and solar gain, will result in steady and comfortable temperature regimes within the building for all occupants. Working in a Garden: The project embraces an indoor/outdoor way of living and working, and the site plan orchestrates this experience to maximum effect. Much of the parking is in an underground garage, affording a generous garden site for the buildings. Approaching visitors and passersby will see the 'California Garden': a broad, sweeping landscape which surrounds the perimeter. With a drought tolerant and climate adaptive planting palette, the 'California Garden' recalls the regional landscape, tailored and refined into a distinctly contemporary garden suited to its Palo Alto setting. A stately oak tree frames the balcony at the most prominent corner of the building, sited on the prow of the rise that sweeps around the Hanover -Page Mill corner. The planting opens up and the topography arcs down to grade as one moves south toward the site entrance, revealing the building monument sign marking the main entrance to the property. A double allee of broad canopy trees flank the main entry, providing a shady grove to welcome visitors. Through the Main Entry Grove, and across the bridge over the drainage channel, the building entrance is approached though a generous central courtyard, composed of a series of garden seating and dining spaces ranging from intimate to spacious in scale, and leading to the main lobby entrance of the building. This main courtyard is mirrored by a smaller, more private courtyard located on the north side of the building. The courtyard planting continues the theme of regionally appropriate, low water use planting, but with a distinctly lush and gardenesque character. The courtyards form the heart of the site and the focal point for occupants of the building, providing ample opportunity for outdoor workplace, meetings, gatherings, dining and retreat. They are designed for optimal outdoor comfort, providing shade, and a range of flexible use spaces in a calming, green setting. Viewed from the office, the landscape provides a verdant backdrop and privacy screen to either the public streets, adjacent buildings or the large interior courtyards. Throughout the site, storm water retention is treated as a garden feature; elegantly planted with fescues and ornamental grasses and integrated into the topography of the site. Generous tree planting around the perimeter and within the courtyards will provide ample shade for years to come.

Additional comments may follow pending revised submittal: OFFSITE Irvl PROVEIVI ENTS: SIDEWALK, CURB & GUTTER: As part of this proJect, the applicant must replace the existing sidewalks, curbs, gutters or driveway approaches in the public right-of-way along the frontages of the property that are damaged or non-standard. Contact the Public Works' inspector at 650-496-6929 to arrange a site visit so the inspector can determine the extent of replacement work. The site plan must show the extent of the replacement work or include a note that Public Works' inspector has determined no work is required. The plan must note that any work in the right-of-way must be done per Public Works' standards by a licensed contractor who must first obtain a Permit tor Construction in the Public Right-ot-Way ("Street Work Permit") from PWE at the Development Center. STREET RESURFACING: The full width of the street shall be resurfaced (grind and overlay) along the frontage of the project on Hanover Street and the Southbound lanes of Page Mill Road. LED STREETLIGHTS: LED streetlights installed per city standards shall be provided on all public streets that front the site. PEDESTRIAN IMPROVEMENTS: Bulb-outs, median refuges, or other improvements to the pedestrian crossing Hanover Street and Page Mill Road shall be considered in accordance with input from the Transportation Division. BICYCLE IMPROVEIVlENTNS: The extent of Hanover street adjacent to the property line of the proposed project may warrant striped Class II bike lanes and associated 4 to 3 auto lane conversion in accordance with the 2012 City , ot Palo Alto Bicycle and Pedestrian Transportation Plan. Additional guidance and input to come from the Transportatron Division. STREET TREES: The applicant may be required to replace existing and/or add new street trees in the public right-of-way along the property's frontage. Call Public Works' arborist at 650-496-5953 to arrange a site visit so he can determine what street tree work will be required for this project. The site or tree plan must show street tree work that the arborist has determined including the tree species, size, location, staking and irrigation requirements. Any removal, relocation or planting of street trees; or excavation, trenching or pavement within 10 feet of street trees must be approved by the Public Works' arborist. The plan must note that in order to do street tree work, the applicant must first obtain a Permit tor Street Tree Work in the Public Right-ot-Way (nStreet Tree Permit'') from Public Worksl Urban Forestry. 1 STORM WATER TREATMENT: This project must meet the latest State Regional Water Quality Control Board's (SRWQCB) C.3 provisions. The applicant is required to satisfy all current storm water discharge regulations and shall provide calculations and documents to verify compliance. All projects that are required to treat storm water will need to treat the permit-specified amount of storm water runoff with the following low impact development methods: rainwater harvesting and reuse, infiltration, evapotranspiration, or biotreatment. However, biotreatment (filtering stormwater through vegetation and soils before discharging to the storm drain system) will be allowed only where harvesting and reuse, infiltration and evapotranspiration are infeasible at the project site. Vault-based treatment will not be allowed as a stand-alone treatment measure. Where stormwater harvesting and reuse, infiltration, or evapotranspiration are infeasible, vault-based treatment measures may be used in series with biotreatment, for example, to remove trash or other large solids. Reference: Palo Alto Municipal Code Section 16.11. 030( c) The applicant must incorporate permanent storm water pollution prevention measures that treat storm water runoff that are site specific. The prevention measures shall be reviewed by a qualified third-party reviewer who needs to certify that it complies with the Palo Alto Municipal Code requirements. This is required prior to the issuance of a building permit. The third-party reviewer shall be acquired by the applicant and needs to be on the Santa Clara Valley Urban Runoff Pollution Prevention Program's (Program) list of qualified consultants. (http://www.scvurpppw2k.com/consultants2012.htm?zoom highlight=con sultants) Any consultant or contractor hired to deSign/and/or construct a storm water treatment system for the project cannot certify the project as a third-party reviewer. Within 45 days of the installation of the required storm water treatment measures and prior to the issuance of an occupancy permit for the building, third-party reviewer shall also submit to the City a certification for approval that the project's permanent measures were constructed and installed in accordance to the approved permit drawings. The project must also enter into a maintenance agreement with the City to guarantee the ongoing maintenance of the permanent C.3 storm water discharge compliance measures. The maintenance agreement shall be executed prior to permit issuance. The applicant is required to paint the "No Dumping/Flows to Matadero Creek" logo in blue color on a white background, adjacent to all storm drain inlets. Stencils of the logo are available from the Public Works Environmental Compliance Division, which may be contacted at (650) 329-2598. A deposit may be required to secure the_ return of the stencil. Include the instruction to paint the logos on the construction grading and drainage plan. Include maintenance of these logos in the Hazardous Materials Management Plan, if such a plan is part of this project. BEST MANAGEMENT PRACTICES (BMP's): The applicant is required to submit a conceptual site grading and drainage plan. In order to address potential storm water quality impacts, the plan shall identify BMP's to be incorporated into the Storm Water Pollution Prevention Plan (SWPPP) that will be required for the project. The SWPPP shall include permanent BMP's to be incorporated into the project to protect storm water quality. (Resources and handouts are available from PWE. Specific reference is made to Palo Alto's companion document to "Start at the Source"[ entitled "Planning Your Land Development Project"). The elements of the PWE-approved 2 conceptual grading and drainage plan shall be incorporated into the building permit plans. The developer shall require the contractor to incorporate BMP's for storm water pollution prevention in all construction operations, in conformance with the SWPPP prepared for the project. It is unlawful to discharge any construction debris (soil, asphalt, sawcut slurry, paint, chemicals, etc.) or other waste materials into gutters or storm drains. (PAMC Chapter 16.09). PARKING STRUCTURE DRAINS: Drains within the covered floors of the parking structures shall be connected to oil-water separators and sanitary sewer lines. Stormwater runoff from any exposed surface or roof parking areas without canopies need to be treated per C.3 requirements. GREASE/OIL REMOVAL DEVICE: If there will be a kitchen and food serving area in the new building, any drains in the food service facilities shall be connected to a grease removal device and located on private property. LOADING DOCK: Any loading dock areas shall be covered and graded so that no storm water enters and flows through the space. Any runoff from the loading dock area shall be kept isolated from the storm drainage system. If the loading area/dock contains a drain, it shall be connected to the sanitary sewer through a manually operated fail-safe valve. SANTA CLARA VALLEY WATER DISTRICT: The proposed project is within 50 feet of a creek or channel which the Santa Clara Valley Water District (SCVWD) has jurisdiction. Prior to the issuance of a building permit, the SCVWD must review the plans and the applicant shall obtain the required permits. Please include relevant permit forms on the plan sheets submitted for a building permit. SANTA CLARA COUNTY ROADS AND AIRPORTS: Page Mill Road faUs under the jurisdiction of Santa Clara County and any work done in the county right of way requires a permit from the Santa Clara County Roads and Airports. PUBLIC ACCESS EASEMENT: The sidewalk at the corner of Page Mill Road and Hanover Street deviates onto private property. A public access easement will be required for the section of sidewalk that overlaps onto private property. The following comments are provided to assist the applicant at the building permit phase. You can obtain various plan set details, forms and guidelines from Public Works at the City's Development Center (285 Hamilton Avenue) or on Public Works' website: http://www.cityofpaloalto.org/gov/depts/pwd/permits.asp Include in plans submitted for a building permit: GRADING & EXCAVATION PERMIT: Since more than 10,000 square feet of the land area on the project site is being disturbed, a Grading and Excavation Permit needs to be obtained from PWE at the Development Center before the building permit can be issued. Refer to the Public Works' website for "Excavation and Grading Permit Instructions." For the Grading and Excavation Permit application, various documents are required including a grading and drainage plan, soils report, Interim and Final erosion and sediment control, storm water pollution prevention plan (SWPPP), engineer-stamped and signed shoring plan, and a copy of the Division of Occupational Safety and Health (DOSH) excavation permit. Refer to our website for "Grading and Excavation Permit Application" and guidelines. Except for the soils report and the DOSH permit, include the required documents and drawings in the 3 building permit set drawings. Indicate the amount of soil to be cut and filled for the project. GRADING AND DRAINAGE PLAN: The plan set must include a grading and drainage plan prepared by a licensed professional that includes existing and proposed spot elevations and showing drainage flows to demonstrate proper drainage of the site. Other site utilities may be shown on the grading plan for reference only, and should be so noted. No utility infrastructure should be shown inside the building footprint. Installation of these other utilities will be approved as part of a subsequent Building Permit application. Site grading, excavation, and other site improvements that disturb large soil areas may only be performed during the' regular construction season (from April 16 through October 15th) of each year the permit is active. The site must be stabilized to prevent soil erosion during the wet season. The wet season is defined as the period from October 15 to April 15. Methods of stabilization are to be identified within the Civil sheets of the improvement plans for approval. SOILS REPORT: A detailed site-specific soil report prepared by a licensed soils or geo-technical engineer must be submitted which includes information on water table and sub-grade construction issues. Measures must be undertaken to render the basement waterproof and able to withstand all projected hydrostatic and soil pressures. No pumping of groundwater is allowed. In general, PWE recommends that structures be constructed in such a way that they do not penetrate existing or projected ground water levels. DEWATERING: Excavation for sub-grade structures may require dewatering. PWE only allows groundwater drawdown well dewatering. Open pit groundwater dewatering is not allowed. If dewatering is required, the dewatering plan must be submitted to Public Works as part of a Street Work Permit. Dewatering is only allowed from April through October due to inadequate capacity in our storm drain system. The geotechnical report for this site must list the highest anticipated groundwater level. If the deepest excavation is expected to be within 3 feet of the highest antiCipated groundwater level, the contractor can determine the actual groundwater depth immediately prior to excavation by installing piezometers or by drilling exploratory holes. Alternatively, the contractor can excavate and hope not to hit groundwater, but if he does, he must immediately stop excavation and submit a dewatering plan to PWE for approval and install a drawdown well system before he continues to excavate. Public Works may require the water to be tested for contaminants prior to initial discharge and at intervals during dewatering. If testing is required, the contractor must retain an independent testing firm to test the discharge water for the contaminants as specified by Public Works. BASEMENT DRAINAGE: Due to high groundwater throughout much of the City, PWE prohibits the ongoing pumping and discharge of groundwater. Sub-grade drainage systems such as perforated pipe drainage systems at the exterior of the basement walls or under the slabs are not allowed. PWE recommends that a waterproofing consultant be retained to design and inspect the vapor barrier and waterproofing systems for the basement. BASEMENT SHORING: Shoring for the basement excavation, including tiebacks, must not extend onto adjacent private property or into the City right-of-way without having first obtained written permission from the private property owners and/or an encroachment permit from PWE at the Development Center. 4 SWPPP: If the proposed development will disturb more than one acre of land, the applicant will be required to comply with the State of California's General Permit for Storm Water Discharges Associated with Construction Activity. This entails filing a Notice of Intent to Comply (NOI), paying a filing fee, and preparing and implementing a site specific storm water pollution prevention plan (SWPPP) that addresses both construction-stage and post-construction BMP's for storm water quality protection. The applicant is required to submit two copies of the NOI and the draft SWPPP to PWE for review and approval prior to issuance of the building permit. STORM WATER POLLUTION PREVENTION: The City's full-sized "Pollution Prevention -It's Part of the Plan" sheet must be included in the plan set. Copies are available from Development Center or on our website. Also, the applicant must provide a site­ specific storm water pollution control plan sheet in the plan set. IMPERVIOUS SURFACE AREA: Since the project will be creating or replacing 500 square feet or more of impervious surface, the applicant shall provide calculations of the existing and proposed impervious surface areas. The calculations need to be filled out in the Impervious Area Worksheet for Land Developments form which is available at the Development Center or on our website, then submitted with the building permit application. WORK IN THE RIGHT-OF-WAY -If any work is proposed in the public right-of-way, such as sidewalk replacement, driveway approach, curb inlet, storm water connections or utility laterals, the following note shall be included on the Site Plan next to the proposed work: "Any construction within the city right-of-way must have an approved Permit for Construction in the Public Street prior to commencement of this work. THE PERFORMANCE OF THIS WORK IS NOT AUTHORIZED BY THE BUILDING PERMIT ISSUANCE BUT SHOWN ON THE BUILDING PERMIT FOR INFORMATION ONLY," LOGISTICS PLAI\J: The contractor must submit a logistics plan to PWE prior to commencing work that addresses all impacts to the City's right-of-way, including, but not limited to: pedestrian control, traffic control, truck routes, material deliveries, contractor's parking, concrete pours, crane lifts, work hours, noise control, dust control, storm water pollution prevention, contractor's contact, noticing of affected businesses, and schedule of work. The plan will be attached to a street work permit. LEASE LINE ADJUSTMENT: According to City of Palo Alto records, multiple leased lots exist within the footprint of the proposed project. Copies of documents associated with the lease line adjustment must shall be completed and ~ttached to the planset prior to issuance of a building permit. FINALIZATION -OF BUILDING PERMIT: The Public Works Inspector shall sign off the building permit prior to the finalization of this permit. All off-site improvements shall be finished prior to this sign-off. Similarly, all as-builts, on-site grading, drainage and post-developments BMP's shall be completed prior to sign-off. 5 From: Mullen, Jarrett Sent: Tuesday, February 19, 2013 3:34 PM To: Campbell, Clare Subject: RE: 1400 Page Mill PWE Comments Hi Clare, Thank you for catching the easement and the stream corridor protection requirements. I incorrectly assumed the drainage channel was not subject to the requirements. However, I checked with Joe Teresi and he confirmed that the stream corridor protection measures do apply for th is project. The channel is known as the "Stanford Channel" and per section 18.40.140 (b)(3)(a), any projects on this site are subject to the regulation. Since the channel already appears to have a reinforced concrete lining, the applicant may be able to obtain an exception to place structures and parking lots within the 20' of the stream bank or a 2:1 slope (horizontal:vertical) from the toe of the bank. The last paragraph of 18.40.140 (b)(3)(a) details the requirements for an exception. I've pasted it below. Exceptions to this requirement may be granted by the director of public works where the applicant provides a geotechnical slope stability analysis, demonstrating that the proposed development would not threaten the stability of the stream bank slope, require introduction of hardscape in order to maintain the stream bank slope, or be at risk of damage from future bank stability or erosion, and demonstrating how maintenance and repair of the stream could be provided with the proposed development in place, subject to compliance with requirements (b) through (i) below and with all applicable zoning setbacks. Let me know if there's anything else you need.

The City is under a legal obligation to meet the provisions of the California Integrated Waste Management Act (AB 939), which requires that 50 percent of the waste generated in the City be diverted from landfill. In 2005, the City adopted a Zero Waste Policy and developed plans to reduce waste to landfills by 73% by 2011 and 90% by 2021. In order to achieve this goal, adequate, accessible, efficient and safe storage of garbage, recyclables and compostables is needed. Provisions for materials storage areas are pursuant to Chapter 5.20 of the Palo Alto Municipal Code (P AMC). Applicability. These guidelines apply to new and modified multi-family (5 or more units) residential developments and non-residential developments. Final approval of the design elements of any project remains with the Architectural Review Board, pursuant to PAMC 18.76.020. Guidelines. 1) Enclosures shall be adequate in capacity, nUITlber and distribution to serve the development. An adequate number of bins and containers to allow for storage and collection of garbage, recyclables and compostables shall be supplied for each enclosure, as specified by the Public Works Department. (PAMC 5.2.080). 2) An enclosure is required for each parcel and must be located on private property and may not be located in alleyways or other City owned rights-of-way, where they may disrupt circulation patterns. (PAMC 5.2.120). 3) Enclosures should accommodate garbage, recyclables and compostables within the same enclosure to allow for equal access and convenience. The design should provide adequate and accessible interior areas so that users of enclosure do not have to shuffle receptacles. 4) The enclosure should be constructed on a flat area with a grade of no more than 2%, in order to ensure that containers can be safely serviced and returned to the enclosure. Enclosure capacity must provide for and maintain adequate space between containers to allow for access to and maneuverability of the containers for service. Enclosures that do not conform may incur additional service fees by the City's waste hauler. 5) The enclosure should be constructed at street level and in a location that is within 25 feet from the street or serviceable area. Enclosures located beyond 25 feet from the street or lof3 S:\PWD\OPS~ MSC\RECYCLING\BuildingandPlanning\ Trash_and ~arbage _enclosure Jequirements\Enclosure _ 20Q9 _ commercial.doc Updated July 2009 serviceable area, or not at street level will incur additional service fees by the City's waste hauler. City's waste hauler does not enter interior areas of buildings. 6) The enclosure may not be located in any required parking, landscape or setback area, or surrounded by curbing that restricts access to the area or enclosure. 7) A concrete apron should be constructed eithe~ in front of each enclosure or enclosure or at the point of receptacle pick-up by the collection vehicle. The concrete apron is necessary to accommodate the weight of the collection vehicle while servicing the enclosure. 8) Collection vehicle travel aisles, including concrete pads, should accommodate a vehicle weight of 60,000 lbs. 9) Receptacle travel/service paths should be constructed of materials to allow unrestricted movement of receptacles and minimize noise disturbances. 10) Driveways or travel paths shall provide unobstructed access for collection vehicles and provide a minimum clearance of 20 feet vertical clearance. A 40-foot turning radius is required for collection vehicles. For safety reasons, a turnaround must be provided for any travel aisle that would otherwise require the collection truck to back up a distance greater than 150 feet. 11) Where enclosures are located in an enclosed area, such as a parking garage, arrangements may be made with the City's waste hauler to have pick-up occur outside the structure. Receptacles cannot block sidewalk, be placed in the street, gutter, or on/in front of utility meters. If pick-up occurs inside the structure, it must meet vehicle access requirements as specified by the City's waste hauler and additional services fees will be incurred. 12) Each enclosure should be enclosed on four sides, one of which includes a gate or door. The contents of the enclosure should be fully screened from public view by masonry or other opaque and durable material. Chain link enclosures are strongly discouraged (P AMC 18.63.030).The gate/door should open the full width of the enclosure. The structure should incorporate the architectural features of the project (PAMC 18.28.030). 13) Storage areas and enclosures must be covered and be designed to prevent water run-on to the area and run-off from the area (PAMC 16.09.106). Drains that are installed beneath dumpsters serving food service facilities, shall be connected to a grease removal device (PAMC 16.09.032). 14) Properties with food service facilities should size enclosures to accommodate storage space for fats/oils/grease collection bins. 15) The property owner is responsible for arranging the pick up of garbage, recyclable and compostable materials. The property owner must maintain the enclosure so that no discarded materials are placed outside of the receptacles or enclosure (PAMC 5.20.130). 2of3 S:\PWD\OPS­ MSC\RECYCLING\BuildingandPlanning\Trash _and_garbage _enclosure Jequirements\Enclosure _2009_ commercial.doc Updated July 2009 16) The property owner must provide unrestricted access to the property for the purpose of collection service. If access is limited to the property, the City's collection service contractor must be given keys or cards to access the property or ensure that access to the property is available by 4:00 a.m. for collection. (PAMC 5.20.150). Multi-Family Specific. 1) Inclusion ofrecyclables and compostables storage space within the interior of the residence, such as a closet or roll-out drawers for containers below the sink. Recommended allocation is three cubic feet. 2) If development includes chutes, then three chutes must be provided directly adjacent to on another for garbage, recyclables and compostables. Chutes should be fire-proof, cleanable, secure. Non-Residential Specific.

Here are my comments on the site plan: • Because net square footage does not increase} a traffic impact analysis will not be required. Vehicle Parking: • For parking lotsl a landscaped island or buffer is needed every 10 spaces (to break up the number of continuous parking stalls). • Provide dimensions of parking stalls and drive aisles and driveways for more detailed review. • Hedges along northwest property line at driveway to Hanover -Keep landscaping to 36" height or lower within 6 feet of back of sidewalk. Bike Parking: • IncllJde bike parking requirement and proposed in calculations on sheet MP 0.1 • All short term bike parking (racks) need to be on the street level within 50 feet of the main public entrances / courtyard. • Short term bike park (racks) are not allowed in the below-grade garage level. Long term bike parking (lockers or secure bike room) may be located in the garage. Thanks} Rafael Rafael Rius, P.E.

BACKGROUND The ground floor space fronting University, outdoor dining plaza and rotunda were remodeled in 2012 for La Boulange Restaurant; the ARB reviewed that application in May 2012. The plans for this project do not reflect the 2012 project, which included corten steel for the entry canopy, the door and window framing, the posts and rails of the railing, and the trim on the rotunda. PROJECT DESCRIPTION The fa<;ade renovation to the existing five-story building would include new clear glass windows, a new steel and glass awning, the removal of the existing curtain wall and column furring, which would be replaced with new aluminum composite metal panels, column covers and soffit. The composite panels are proposed to wrap the exterior columns, cornice and interstitial area between 12PLN-00402 Page 1 of3 the first and second floor. A new window system would replace the existing system above the first floor. The applicant proposes to replace the existing entry canopy at the south comer with a new canopy that wraps the building and extends down the High Street elevation. No favade modifications are proposed for the rotunda, first floor window system, or internal areas within the exterior shell. The north egress tower would be painted an off-white color, "China White". The materials board will be displayed at the public hearing. Project building materials include composite metal panels, clear dual-glazed anodized aluminum windows, fritted glass, laminated glass, and stainless steel canopy frame. The comer architectural treatment would include clear glass curtain wall extending above the existing roofline. Two low wattage, 3" diameter LED light fixtures would light a future sign that is envisioned to be placed at the top of the comer system (see Attachment F). No signage is proposed at this time. DISCUSSION Context-Based Design Considerations and Findings The site is subject to both Architectural Review approval and Context-Based Considerations and Findings pursuant to Palo Alto Municipal Code (P AMC) 18.18.11 O(b). To facilitate ARB discussion, the Architectural Review findings are provided as Attachment A and the context based considerations are provided as Attachment B. Downtown Urban Design Guide The purpose of the Downtown Urban Design Guidelines is to advise the applicant, staff and the ARB on downtown development design. The document was not intended to be a regulatory document. The subject site is located in an area defined as the University Avenue District, which is identified as the center of the downtown area. The University Avenue District, one of seven distinctive districts, is known for heightened activity and liveliness on the street. It is also known as an important vehicular and pedestrian corridor. The Guidelines recommend reinforcing the retail core by maintaining the strong connection of ground floor uses between Alma and Cowper Streets. It also recommends encouraging the development and enhancement of the qualities of University Avenue which make it an exciting outdoor and pedestrian environment. Those qualities include the vibrant and eclectic architecture, outdoor food service and entertainment. The project proposal is to update and revitalize an existing commercial/office building with distinctive modem finishes. The glass canopy is proposed to wrap the building and extend down High Street. The wrapping canopy provides a more pedestrian feel to the comer, adding greater interest to the pedestrian level. The restaurant and outdoor eating area will remain. The favade renovation to the site will enhance the prominent comer and pedestrian experience. The design generally conforms to the Guidelines. Pedestrian Combining District The pedestrian Co:rnbining District is intended to foster the continuity of retail stores and display windows and to avoid a monotonous pedestrian environment in order to establish and maintain a healthy retail district. Palo Alto Municipal Code (P AMC) Chapter 18.30 charges the ARB to ensure compliance with regulations. Proposals must include design features intended to create pedestrian or shopper interest, to provide weather protection for pedestrians and to preclude blank 12PLN·00402 Page 2 of3 walls or building faces. The applicant proposes a new window system to replace the existing system above the first floor. The project includes the wrapping canopy system around the building. As noted there is no work included to the existing rotunda, first floor window system or outdoor seating area. The proposed renovation will enhance the pedestrian experience. ENVIRONMENTAL REVIEW Pursuant to the requirements of California Environmental Quality Act (CEQA), the project is categorically exempt from CEQA, per Section 15301, Existing Structures.

The design of new projects shall promote pedestrian walkability, a bicycle friendly environment, and connectivity through design elements. The proposed building renovations would increase a pedestrian canopy, maintain existing setbacks, and maintain the outdoor dining area, creating an inviting and active pedestrian environment. 2) Street Building Facades. Street facades shall be designed to provide a strong relationship with the sidewalk and the street (s), to create an environment that supports and encourages pedestrian activity through design elements. The overall design intent is to update and modernize the building's exterior materials. The proposed project would upgrade and improve the building's appearance, maintaining the existing restaurant on the ground level that would continue to contribute to an active pedestrian oriented area. 3) Massing and Setbacks. Buildings shall be designed to minimize massing and conform to proper setbacks. The building fa9ade is generally consistent with nearby building facades and setbacks. The proposal would not alter the existing locations, setbacks, or size of the building. 4) Low Density Residential Transitions. Where new projects are built abutting existing lower scale residential development, care shall be taken to respect the scale and privacy of neighboring properties. The building is not directly adjacent to residential development and would not impact the privacy or scale of residential properties. 5) Project Open Space: Private and public open space shall be provided so that it is usable for the residents and visitors of the site. The project would not reduce pedestrian access to and from the site and would maintain the existing sidewalk width. 6) Parking Design: Parking shall be accommodated but shall not be allowed to overwhelm the character of the project or detract from the pedestrian environment. The project is not required to provide any additional parking as no new floor area would be added to the existing building. 151 University Avenue (PLN-000402) Page 1 of2 In conclusion, the proposed project at 151 University Avenue [12PLN-00402] is consistent with the Context-Based Design Criteria for all of the reasons and findings specified above. 151 University Avenue (PLN-000402) Page 2 of2 ATTACHMENT C CONDITIONS OF APPROVAL 151 University Avenue 12PLN-000402 Planning and Environmental Division 1.

Composite panels will wrap the exterior columns, cornice, and interstitial area between the 'first and second floor. A new window system and protruding corner window system will replace the exiting .system above the first floor. We propose to replace the entry canopy at the south corner of the building with a new canopy that wraps the building and extends down High St. We find the design adds emphasis to the corner entry. The change to rectilinear geometry helps the corner read as an intersection of elements. There is no work to the existing rotunda, 'first floor window system, or internal areas within the exterior shelf. We propose to paint the north egress tower. Materials include cbmposite metal panels, clear dual-glazed anodized aluminum windows, fritted glass, laminated glass, stainless steel canopy frame, and two low wattage 3" diam. LED light fixtures at the top of the corner system to illuminate signage. 3.
