SEC TION 3. Planned Community Findings
Finding #1: The site is so situated, and the use or uses proposed for the site are of such characteristics that the application of general districts or combining districts will not provide sufficient flexibility to allow the proposed development.
T
he project is consistent with Finding #1 because:
The proposed project includes provides larger, family-serving units, as well as additional affordable housing units. This requires exceeding the allowable floor area, lot coverage, and height to achieve. Additionally, to provide this number of family-serving units, there is less available space on site to provide commercial space and parkland dedicated land. The project is otherwise in compliance with Zoning district requirements.
Finding #2: Development of the site under the provisions of the PC planned community district will result in public benefits not otherwise attainable by application of the regulations of general districts or combining districts. In making the findings required by this section, the planning commission and city council, as appropriate, shall specifically cite the public benefits expected to result from use of the planned community district.
The project is consistent with Finding #2 because:
The primary public benefit for this project is additional housing units to assist the City in reaching their Regional Housing Needs Assessment goals. The project proposes 75 units, the majority of which are 2- and 3-bedrooms to serve families. The project proposes 20% of the units to be designated Below Market Rate, including 6 very-low income, 5 low-income, and 4 moderate-income.
Finding #3: The use or uses permitted, and the site development regulations applicable within the district shall be consistent with the Palo Alto Comprehensive Plan, and shall be compatible with existing and potential uses on adjoining sites or within the general vicinity.
The project is consistent with Finding #3 because:
This project is consistent with the Palo Alto Comprehensive Plan, as described further in Architectural Review Finding #1 below. The surrounding uses are currently mostly one- to two-story buildings with commercial/personal services, office use, and similar uses. The site is adjacent to an approved mixed use, 4 -story building at 788 San Antonio which is currently in the building permit process. This project is located in the Housing Incentive Program corridor, which allows for higher density residential uses along a portion of San Antonio Road and is anticipated to change the overall character of the neighborhood in this area from low -density commercial uses to high -density residential uses over time.
SECTION 4. Architectural Review Findings
Finding #1: The design is consistent with applicable provisions of the Palo Alto Comprehensive Plan, Zoning Code, coordinated area plans (including compatibility requirements), and any relevant design guides.
The project is consistent with Finding #1 because:
I
n conformance with the following Comp Plan Goals and Policies, the project will include high quality design compatible with surrounding development.
Comp Plan Goals and Policies How project adheres or does not adhere to Comp Plan
The Comprehensive Plan land use designation for
the site is Service Commercial.
The project proposes high-density housing in an
area designated for high-density housing.
Land Use Element
Policy L-1.3 Infill development in the urban
service area should be compatible with its
surroundings and the overall scale and character
of the city to ensure a compact, efficient
development pattern.
This project proposes to redevelop three existing
commercial buildings into a single multiple-family
residential condominium building within the
Housing Incentive Program (HIP) area.
Policy L-2.5 Support the creation of affordable
housing units for middle to lower income level
earners, such as City and
school district employees, as feasible.
This project includes 15 BMR units.
Policy L-2.11 Encourage new development and
redevelopment to incorporate greenery and
natural features such as green
rooftops, pocket parks, plazas and rain gardens.
The proposed building includes a central
courtyard and rooftop garden.
Policy L-6.1 Promote high-quality design and site
planning that is compatible with
surrounding development and public
spaces.
The proposed residential building is being
considered within the context of other projects
being developed in the HIP area, and will meet
the high-quality standards of the Architectural
Review Board.
Policy L-6.7 Where possible, avoid abrupt
changes in scale and density between residential
and non-residential areas and between
residential areas of different densities. To
promote compatibility and gradual transitions
between land uses, place zoning district
boundaries at mid-block locations rather than
along streets wherever possible.
While the proposed project is somewhat out-of-
scale with the existing neighbor to the left, it is
similar in density and scale to the HIP project
approved for the right side adjacent neighbor,
and other projects proposed for the HIP area.
Policy T-1.19 Provide facilities that encourage
and support bicycling and walking.
The building includes sufficient short and long
term bicycle parking.
A
s a PHZ project, the zoning development standards are custom built for the building, and therefore this project will be in compliance with zoning through the ap proval process. No other design guidelines or documents apply to this location.
Finding #2: The project has a unified and coherent design, that:
a. creates an internal sense of order and desirable environment for occupants, visitors, and the general community
,
b. pr
eserves, respects and integrates existing natural features that contribute positively to the site and
the historic character including historic resources of the area when relevant, c. is consistent with the context-based design criteria of the applicable zone district, d. provides harmonious transitions in scale, mass and character to adjacent land uses and land use designations,
e. enhances living conditions on the site (if it includes residential uses) and in adjacent residential areas.
The project is consistent with Finding #2 because:
There is internal order between the pedestrian entries, car entry, retail space and amenity space. There are separate, defined entrances for the residents and retail tenant. There is no historic character to preserve.
The proposed five story building is consistent with the applicable context- based design criteria, and scale, mass, and character is consistent with prior and proposed projects anticipated for the HIP area.
Finding #3: The design is of high aesthetic quality, using high quality, integrated materials and appropriate construction techniques, and incorporating textures, colors, and other details that are compatible with and enhance the surrounding area.
The project is consistent with Finding #3 because:
The project incorporates a variety of materials, including glass, gray and beige equitone panels, blue and brown metal panels, and landscape elements. This palette is appropriate for a residential building, and relates to the adjacent 788 San Antonio project while being distinct.
Finding #4: The design is functional, allowing for ease and safety of pedestrian and bicycle traffic and providing for elements that support the building’s necessary operations (e.g. convenient vehicle access to property and utilities, appropriate arrangement and amount of open space and integrated signage, if applicable, etc.).
The project is consistent with Finding #4 because:
The design is functional. The bicycle parking is located at the ground level; the car parking is provided below grade, with driveway access at the northern end of the project site. The tenants will have private balcony space, and communal open space in the courtyard and rooftop garden. The building includes separate trash rooms for the commercial and residential components, and a loading space is located off of San Antonio Road, as well as in the below-grade garage. The primary entrances for the residential and the commercial spaces are well-defined with appropriate area available for signage.
Finding #5: The landscape design complements and enhances the building design and its surroundings, is appropriate to the site’s functions, and utilizes to the extent practical, regional indigenous drought resistant plant material capable of providing desirable habitat that can be appropriately maintained.
The project is consistent with Finding #5 because:
The project is consistent with the finding in that the project provides landscaped area in the front, rear, central courtyard, and rooftop garden. Three existing trees, including two protected Coast Live Oak, will be preserved. All plants proposed are low to moderate water use, and most are native or regionally adapted.
Finding #6: The project incorporates design principles that achieve sustainability in areas related to energy
efficiency, water conservation, building materials, landscaping, and site planning.
The project is consistent with Finding #6 because:
In accordance with the City’s Green Building Regulations, the building will satisfy the requirements for CALGreen Mandatory + Tier 2. The project includes a “cool” high albedo membrane roof, electric vehicle charging outlets, and drought tolerant and native landscaping.

T
he Addendum to the Housing Incentive Program Expansion and 788 San Antonio Road Mixed-Use Project Environmental Impact Report (SCH # 2019090070) identifies the mitigation measures that must be implemented to reduce the impacts associated with the project. The California Environmental Quality Act (CEQA) was amended in 1989 to add Section 21081.6, which requires a public agency to adopt a monitoring and reporting program for assessing and ensuring compliance with any required mitigation measures applied to proposed development. As stated in section 21081.6(a)(1) of the Public Resources Code:
... the public agency shall adopt a reporting or monitoring program for the changes made to the project or conditions of project approval, adopted in order to mitigate or avoid significant effects on the environment.
Section 21081.6 also provides general guidelines for implementing mitigation monitoring programs and indicates that specific reporting and/or monitoring requirements, to be enforced during project implementation, shall be defined as part of adopting an IS-MND.
The mitigation monitoring table lists those mitigation measures that would be included as conditions of approval for the project. To ensure that the mitigation measures are properly implemented, a monitoring program has been devised which identifies the timing and responsibility for monitoring each measure.

AIR QUALITY
A
Q-1 Construction Mitigation. For individual projects in the HIP expansion area that exceed the BAAQMD air
pollutant and precursor screening levels, the project
proponent for that particular development shall conduct a quantifiable analysis to measure construction-related impacts to air quality for all construction phases as
described in the BAAQMD CEQA Guidelines (2017). If
project construction would exceed BAAQMD thresholds
for criteria pollutants, the City shall require the
construction contractor(s) to implement additional
BAAQMD-approved measures beyond Basic Control
requirements and demonstrate that such measures
would reduce emissions to below thresholds. Additional
measures for development projects that exceed
significance criteria may include, but are not limited to:
1. All exposed surfaces shall be watered at a
frequency adequate to maintain minimum soil
moisture of 12 percent. Moisture content can be
v
erified by lab samples or moisture probe.
2. All excavation, grading, and/or demolition
activities shall be suspended when average wind
s
peeds exceed 20 mph.
3. Wind breaks (e.g., trees, fences) shall be installed on the windward side(s) of actively disturbed
ar
eas of construction. Wind breaks should have
at maximum 50 percent air porosity.
4. Vegetative ground cover (e.g., fast-germinating
native grass seed) shall be planted in disturbed

areas as soon as possible and watered
appropriately until vegetation is established.
5. The simultaneous occurrence of excavation,
grading, and ground-disturbing construction
activities on the same area at any one time shall
be limited. Activities shall be phased to reduce
the amount of disturbed surfaces at any one
time.
6. All trucks and equipment, including their tires,
shall be washed off prior to leaving the site.
7. Site accesses to a distance of 100 feet from th
e
p
aved road shall be treated with a 6 to 12-inch
compacted layer of wood chips, mulch, or gravel.
8. Minimizing the idling time of diesel-powered
construction equipment to two minutes.
9. The project shall develop a plan demonstrating
that the off-road equipment (more than 50
horsepower) to be used in the construction
p
roject (i.e., owned, leased, and subcontractor
vehicles) would achieve a project wide fleet-
average 20 percent NOX reduction and 45
pe
rcent PM reduction compared to the most
recent ARB fleet average. Acceptable options for
reducing emissions include the use of late model
engines, low-emission diesel products,
alternative fuels, engine retrofit technology,
after-treatment products, add-on devices such as
particulate filters, and/or other options as suc
h
b
ecome available.
10. Use low VOC (i.e., ROG) coatings beyond the
local requirements (i.e., Regulation 8, Rule 3:
Architectural Coatings).
11. Requiring that all construction equipment, diesel
trucks, and generators be equipped with Best
Available Control Technology for emission
reductions of NOX and PM.

12. Limiting import/export of soils or limiting the
number of hauling trips per day to reduce
emissions of NOX associated with hauling truck
trips.
13. Phasing construction activities to reduce daily
equipment use.
BIOLOGICAL RESOURCES
BIO-1 Nesting Bird Surveys and Avoidance – HIP expansion area. Construction, grading, site preparation and other ground-disturbing activities required for development
allowed by the proposed HIP expansion that would
involve vegetation or tree removal shall be prohibited
during the general avian nesting season (February 1 –
August 31), if feasible. If nesting season avoidance is not feasible, the applicant shall retain a qualified biologist, as approved by the City of Palo Alto, to conduct a
preconstruction nesting bird survey to determine the
presence/absence, location, and activity status of any
active nests on or adjacent to the development site. The extent of the survey buffer area surrounding the site
shall be established by the qualified biologist to ensure that direct and indirect effects to nesting birds are
avoided. To avoid the destruction of active nests and to protect the reproductive success of birds protected by
the MBTA and CFGC, nesting bird surveys shall be
performed not more than 14 days prior to scheduled
vegetation clearance and structure demolition. In the
event that active nests are discovered, a suitable buffer (typically a minimum buffer of 50 feet for passerines and a minimum buffer of 250 feet for raptors) shall be
established around such active nests and no construction shall be allowed within the buffer areas until a qualified biologist has determined that the nest is no longer active (i.e., the nestlings have fledged and are no longer reliant on the nest). No ground disturbing activities shall occur within this buffer until the qualified biologist has
confirmed that breeding/nesting is completed and the

BIO-2 Special-Status Plant Species Botanical Surveys. A qualified biologist shall conduct a protocol level botanical survey, including a site visit during the blooming period of the target species in March through July. If the CRPR 1 rank plant is found, the plants shall be avoided by
installing protective fencing and warning construction
personnel of their presence through the WEAP training.
If special-status plants species cannot be avoided,
impacts shall be mitigated at a minimum ratio of 1:1
(number of acres or individuals restored to number of
acres or individuals impacted). A restoration plan shall be prepared and submitted to the City for review and
approval and to CDFW for review. The restoration plan
shall include, at a minimum, the type and area of habitat to be established, restored, enhanced, and/or preserved; goals and objectives of the mitigation project; a
monitoring plan including performance standards and
success criteria; and maintenance activities to occur
during monitoring. The applicant shall implement the
measures prior to commencement of ground

mufflers and engine shrouds, as applicable, shall
be in good condition and appropriate for the
equipment. During construction, all equipment,
fixed or mobile, shall be operated with closed
engine doors and shall be equipped with
properly operating and maintained mufflers,
consistent with manufacturers’ standards.
Electrical Power. Electrical power, rather than
diesel equipment, shall be used to run
compressors and similar power tools and to
power temporary structures, such as
construction trailers or caretaker facilities.
Equipment Staging. All stationary equipment
(e.g., air compressors, portable generators) shall
be staged as far away from sensitive receptors as
feasible. Where feasible, construct temporary
noise barriers around stationary equipment in a
manner that fully blocks the line of sight to
residential windows in the adjacent apartment
complex.
Equipment Idling. Construction vehicles and
equipment shall not be left idling for longer than
five minutes when not in use.
Workers’ Radios. All noise from workers’ radios
shall be controlled to a point that they are not
audible at sensitive receptors near construction
activity.
Smart Back-up Alarms. Mobile construction
equipment shall have smart back-up alarms that
automatically adjust the sound level of the alarm
in response to ambient noise levels.
Alternatively, back-up alarms shall be disabled
and replaced with human spotters to ensure
safety when mobile construction equipment is
moving in the reverse direction.
Sound Barrier. During the demolition, site
preparation, grading, building, and paving phases

of construction, temporary sound barriers shall
be installed and maintained facing sensitive
receptors (e.g., residential units, educational
facilities) located within 100 feet of the center of
construction activity. Temporary sound barriers
shall, at a minimum, block the line of sight
between noise-generating construction
equipment and adjacent windows at sensitive
receptors and shall be placed as close to the
source equipment as feasible. Such barriers shall
be field tested to reduce noise by at least 10 dBA
at sensitive receptors. A sound barrier can
achieve a 5 dBA noise level reduction when it is
tall enough to break the line-of-sight from the
source equipment to the sensitive receptor, and
it can achieve an approximate 1 dBA additional
noise level reduction for each 2 feet of height
after it breaks the line of sight (FHWA 2011).
Mobile sound barriers may be used as
appropriate to attenuate construction noise near
the source equipment.
Disturbance Coordinator. The applicant shall
designate a disturbance coordinator who shall be
responsible for responding to any local
complaints about construction noise. The noise
disturbance coordinator shall determine the
cause of the noise complaint (e.g., starting too
early, bad muffler) and shall require that
reasonable measures warranted to correct the
problem be implemented. A telephone number
for the disturbance coordinator shall be
conspicuously posted at the construction site.

redirected until an archaeologist has evaluated the
nature and significance of the find and an appropriate
Native American representative, based on the nature of
the find, is consulted. If the County, in consultation with local Native Americans, determines that the resource is a tribal cultural resource and thus significant under CEQA, a mitigation plan shall be prepared and implemented in
accordance with state guidelines and in consultation with Native American groups. The plan would include
avoidance of the resource or, if avoidance of the
resource is infeasible, the plan would outline the
appropriate treatment of the resource in coordination
with the archeologist, if applicable, and the appropriate Native American tribal representative.
