(Initial and Ongoing Vegetation Management
Activities): Red-legged Frogs. Before any construction

included in construction/vegetation management
contracts:
i. Vegetation Stockpiles. Because California redlegged frogs could move into areas under debris piles, where they could then be injured or killed
when the debris piles are disposed of, debris
intended for burning, mastication, or other
disturbance, should not be piled on the ground
within 100 feet of any riparian area unless the piles
would be treated on the same day that they are
created. If vegetation piles cannot be treated or
removed daily, they should be dispersed on the
site, to the extent feasible.
ii. Trash Containment during Construction and
vegetation management Activities. Because human
trash associated with construction activities and
vegetation management activities has the
potential to attract predators, all trash shall be
contained in sealed containers and disposed of on
a daily basis.
iii. Mechanical Support for Vegetation Management.

If off-road mechanical support is necessary for
ongoing vegetation management activities,
Mitigation Measure Bio-2a shall be implemented

Before any construction or vegetation management
activities involving off-road mechanical support begin, the following measures shall be completed and/or
included in construction contracts:
i. Pre-activity Survey. No more than 30 days prior to
any initial ground disturbance or vegetation
removal activities, a pre-activity survey for
woodrat nests shall be conducted by a qualified
biologist within areas where ground disturbance or
vegetation removal shall be conducted and within
10 feet of the disturbance and vegetation removal
areas.
ii. Disturbance-Free Buffers. If feasible, a minimum
10-ft buffer shall be maintained between project
construction activities and each nest to avoid
disturbance. In some situations, a smaller buffer
may be allowed if in the opinion of a qualified
biologist, removing the nest would be a greater
impact than that anticipated due to project
activities. Environmentally sensitive area (ESA)
fencing shall be installed to mark the buffer area
around potentially impacted woodrat nests to
keep workers, construction equipment, and
construction materials out of the area where the
nests are located.

relocation plan shall be prepared by a qualified
biologist prior to initial ground disturbance or
vegetation removal activities. At a minimum, the
plan shall include woodrat nest relocation
methods, relocation site habitat requirements,
appropriate relocation sequence with respect to
vegetation management activities, spacing of
nests, timing of relocations, and recommended
protective buffers around nests proposed to
remain in place. The plan shall also include a map
of all woodrat nests, and proposed relocation
areas. Relocation of nest materials shall follow the
following guidance:

If it is determined that disturbance of woodrat
nests cannot be avoided, the woodrats shall be
evicted from their nests prior to the removal of the
nests and onset of ground-disturbing activities to
avoid injury or mortality of the woodrats.

Relocation activities shall follow methods outlined
in the Woodrat Relocation Plan. A qualified
biologist shall monitor and direct all activities
associated with the removal of dusky-footed
woodrat nests (structures). Only as necessary and
to the minimum extent possible, project site
vegetation shall be removed to provide access to
the woodrat nest(s). Following the removal of
vegetation required to access woodrat nests, a
fiber-optic camera shall be used to observe inside
the nest to determine its occupancy prior to
beginning the dismantling process. If young are not
observed, the nest shall be fully dismantled and
materials shall be relocated, as described below. If
dependent young are present, the protocol for

active nests below shall be followed to dismantle
the structure over a two-week period.

Except where dependent young are present,
woodrat structures or nests shall slowly and
progressively be dismantled during a single site
visit. Appropriate personal protective equipment
(e.g. respirator, gloves, and Tyvek suit) shall be
used while dismantling and relocating woodrat
nest material to protect against disease carried by
rodents (e.g., hantavirus). Where feasible, nesting
material or food caches shall be moved to a new
location at least 30 feet outside the disturbance
area, preferably next to a large tree or similar
structure in a riparian or oak woodland habitat, in
an area where it can be used by woodrats to
construct new nests. If no suitable structure is
present, a log pile structure may be constructed to
support the nest materials.

If young are uncovered within the nest prior to or
during the dismantling process, dismantling of the
nest shall be suspended for a period of two weeks
to allow young to develop eyesight and become
mobile. Nest materials shall be placed back on top
of the nest to re-cover the exposed young. After
the two-week period, the above removal
procedures shall be resumed. Within 24 hours of
vegetation removal and completion of nest
dismantling, an additional survey shall be
conducted to confirm no new woodrat nests were
constructed.

encourage day-roosting bats to leave potential
roost trees ahead of tree removal. This process
involves removing small branches and small limbs
containing no day-roost habitat (e.g., crevices) on
habitat trees on Day 1, using chainsaws only. The
following day (Day 2), the remainder of the tree is
to be removed. The disturbance caused by
chainsaw noise and vibration, combined with the
physical modification of the tree, is expected to
cause day- roosting bat species to abandon the
roost tree after nightly emergence for foraging.

Trimmed habitat trees must be removed the next
day to prevent re-occupation of trimmed trees.

If suitable roost trees are not proposed for removal
but would undergo a specific treatment (e.g.,
thinning, crown raising), disturbance shall be
scheduled to take place outside the maternity
roost season. If treatment activities cannot occur
outside the maternity season, a pre-activity
evening survey shall be conducted by a qualified
biologist to determine if the tree is occupied by a
maternity colony. If no bats are detected, work
may proceed without any additional surveys. If a
maternity colony is present, work shall be
postponed until the end of the maternity season
(August 31).
ii. Pre-activity Survey for Work within Pallid Bat
Maternity Season (March through August). Prior to
any initial ground disturbance or off-road
mechanical vegetation removal activities, or
removal or modification of trees to occur during
Pallid Bat Maternity Season, a pallid bat roost
habitat assessment shall be conducted for all trees

and structures on and within 150 feet of the
location of the activity, during the appropriate
time of year when bats would be detectable
(March 1 – August 31). A qualified bat biologist
shall conduct the survey to look for evidence of bat
use within suitable habitat. If evidence of use is
observed, or if high-quality roost sites are present
in areas where evidence of bat use might not be
detectable (such as a tree cavity), an evening
survey and/or a nocturnal acoustic survey may be
necessary to determine if a bat colony is present
and to identify the specific location of the bat
colony.
iii. Avoidance. If an active pallid bat maternity colony or non-breeding roost is located, construction
work or vegetation activities shall be redesigned to
avoid disturbance of the roost, if feasible.
iv. Eviction and Alternative Roost Habitat. If an active pallid bat maternity colony or non-breeding bat
roost is located and construction work cannot be
redesigned to avoid removal or disturbance of the
occupied roost, the individuals shall be safely
evicted by a qualified bat biologist between August
1 and October 15 or between February 15 and
March 15, with the timing determined by a
qualified bat biologist.

If eviction is necessary, alternative roost habitat shall be provided at least 30 days prior to eviction of bats
from the roost. A qualified bat biologist shall
determine the appropriate location for the alternative
roost structure, based on the location of the original
roost and habitat conditions in the vicinity, and
oversee installation of a new roost structure. The

structure shall be placed as close to the affected roost site as feasible, taking into account potential for
disturbance during construction on the site (e.g., the
roost might be placed elsewhere on the larger project
site). The roost structure either shall be built to
specifications determined by a qualified bat biologist
or, with approval of a qualified bat biologist as to
structure type, shall be purchased from an
appropriate vendor. Stanford University shall monitor
the roost for up to three years (or until occupancy is
determined, whichever occurs first) to determine use
by bats. If, by Year 3, pallid bats are not using the
structure, a qualified bat biologist, in consultation
with CDFW, shall identify alternative roost designs or
locations for placement of the roost, place the new
roost at the agreed-upon location, and monitor the
new roost for an additional three years (or until
occupancy has been verified).

riparian habitat within the project site consists of a
mature overstory composed of California bay,
California buckeye, and coast live oak. Riparian
vegetation may be removed during vegetation
treatment activities. All trees removed within mixed
riparian forest habitat shall be replaced with the same species that was removed during project
implementation, which shall be planted within the
same reach where impacts occur or along streams on

other vegetation) that are scheduled to be
removed by these project features may be
removed prior to the start of the nesting season
(e.g., prior to January 15). This would preclude the
initiation of nests in this vegetation and prevent
the potential delay of the project construction due
to the presence of active nests in these substrates.
iii. If it is not possible to schedule construction or
vegetation management activities between
September 16 and January 14, then pre-activity
surveys for nesting birds should be conducted by a
qualified ornithologist to ensure that no nests shall
be disturbed during project implementation. These
surveys shall be conducted no more than seven (7)
days prior to the initiation of all project activities.

During this survey, the ornithologist shall inspect
all trees and other potential nesting habitats (e.g.,
shrubs, ruderal grasslands, trees, horse paddocks)
in and immediately adjacent to the impact areas
for nests.
iv. If an active nest is found sufficiently close to work areas to be disturbed by these activities, the
ornithologist shall determine the extent of a
construction- or disturbance-free buffer zone to be
established around the nest (typically 300 feet for
raptors and 100 feet for other species), to ensure
that no nests of species protected by the MBTA
and California Fish and Game Code shall be
disturbed during Project implementation. On a
case by case basis, the ornithologist may
determine that another buffer distance is
appropriate based on the species, the height and
concealment of the nest, vegetation or topography

Mitigation Measure Bio-13b: Maintain Nesting
Substrate during Vegetation Management. To the
extent feasible, maintain a variety of tree, shrub, and herbaceous nesting substrates during vegetation
management activities. This would involve
maintaining (1) plant species diversity, and structural and age class diversity to accommodate a variety of
tree-nesting species, (2) islands or scattered locations of live and dead or dying trees that support nest
cavity habitat, and (3) islands or scattered locations

Portola Terrace Homes
Stanford University
Project Narrative
September 23, 2024
Overview
Stanford University (Stanford) proposes to develop a portion of University property (often referred to as the “Stanford Wedge”) in the Town of Portola Valley to create 27 single-family residences for Stanford faculty and 12 affordable multifamily housing units. Approximately 10% of the entire project site would be developed, and the remainder of the

75.4-acre site would be preserved as open space. Development would be clustered in the small portion of the property that is flattest and closest to existing infrastructure.

The project objectives are to:
• Maximize single-family housing opportunities in an area the Town has studied and approved for housing. • Include sufficient affordable housing to make progress toward the Town’s fair share low-income housing needs under the Housing Element of the Town’s General Plan, enable a density bonus, and comply with the Town’s inclusionary housing ordinance.
• Cluster development located closest to existing infrastructure on relatively flat land, in a manner that preserves substantial open space and steep slopes in order to foster a sense of community.

Project Site
The project site is a triangular-shaped property of approximately 75.4 acres commonly called the Stanford Wedge property. It is located immediately west of Alpine Road in the northeastern part of the Town. (APN 077-281-020). The site is largely undeveloped, but the portion of the site proposed for development is currently occupied by the Alpine Rock Ranch, a horse boarding facility with stables. Elevations within the project site range from approximately 323 feet to 678 feet above sea level, but the development site is limited to a relatively flat portion along Alpine Road that is surrounded by steep hillsides to the sides and rear of the property.

The Glenoaks Stables are located across Alpine Road from the southeastern boundary of the site. Single-family homes are located to the north, west, and south of the project site.

The property is designated “Conservation-Residential” in the General Plan. That designation includes relatively accessible undeveloped lands with some potential geologic instabilities, which are to be developed using a slopeintensity standard. The Town’s 2015 Housing Element contemplates single-family homes on the site and affordable housing that can help meet the Town’s Regional Housing Needs Allocation (RHNA) requirements.

The site is zoned Residential Estate (R-E) and is subject to the 3.5A residential density combining district, the SD-2 slope-density combining district, and the D-R design review combining district.

Physical Development
The maximum allowable density at the site is governed by the Municipal Code and the State Density Bonus Law (Government Code section 65915). Municipal Code sections 18.50.040 and 18.50.050(A) impose a slope-density formula that yields just over 20 lots for the site. Municipal Code sections 17.20.215, 18.04.055 and 18.44.060(H) allow and require inclusionary housing that may be configured as multifamily housing, resulting in a maximum base density of 18 single-family units and 12 multifamily affordable units (or 30 total base units). By restricting 20% of these units to low-income households, the project qualifies under state law for a 35% density bonus, which would allow 11 additional market-rate units. The project proposes 9 units rather than 11 bonus market-rate units, resulting in a total of 27 market-rate single-family homes and 12 affordable multifamily units on a total of 30 developable lots.

This actual development footprint would be clustered on roughly 6 acres (or 8% of the total site area) of the flattest and most readily developable area of the property next to Alpine Road.

The 27 single-family homes would be located on clustered lots as a planned unit development. Most of these homes would be separated from each other, while 6 of the homes would be configured into 3 duets. Each single-family home would be located on its own lot. The homes would be two stories, each having three or four bedrooms and a study. No accessory dwelling units would be constructed as part of the project. The single-family homes are anticipated to range from approximately 1,800 square feet to 2,100 square feet. Parking in the amounts required by the State Density Bonus Law would be accommodated through a combination of one-car garages and uncovered parking spaces primarily located on each lot. Lot sizes would be in the range of 3,300 to 4,800 square feet. These lot sizes are smaller than those permitted by local zoning but would be permitted pursuant to a State Density Bonus Law incentive/concession. The individual homes would have private fenced rear yards. Each single-family lot would be subject to a ground lease.

The floor areas for different unit types represent gross areas. Gross areas were calculated by summing all of the area within the face of exterior walls at each floor of the building. Stairs are only counted towards the area of the first floor of the building.

Affordable units
Under the Town of Portola Valley’s inclusionary lot requirements, three lots must be developed as affordable housing. Up to 4 affordable units may be placed on each lot provided under the inclusionary housing program, allowing up to 12 multifamily affordable units on the property. At least 6 of the 12 affordable units would be set aside for low-income households.

The 12 multifamily rental units would be clustered on three lots of approximately 6,200 to 8,300 square feet each, with a four-unit building on each lot. Each multifamily building would contain two studio units (approximately 475 SF each), one 1-bedroom unit (approximately 600 SF), and one 2-bedroom unit (approximately 975 SF). The project would provide parking consistent with the requirements of the State Density Bonus Law.

Architectural Style
The intent of the town of Portola Valley Design guidelines are to encourage architectural design that is:
• responsive to the site;
• in harmony with the natural environment;
• compatible with the surrounding neighborhood;
• in keeping with the rural character of the town.

Colors and materials:
• Use colors and materials that blend with the natural environment. • Do not use highly reflective colors and surfaces.
• Concrete driveways visible from off-site should be darkened to blend with the natural environment. • For new construction and remodeling projects that come before the ASCC, colors shall be subject to ASCC approval. The reflectivity value for colors should not exceed 40%, except that the colors for trim should not have a reflectivity value over 50%.
• Homeowners and developers are encouraged to follow the above reflectivity values when repainting buildings.
• Light colored roofs are discouraged and in general should not exceed a reflectivity value of 40%, especially if visible from off site.

The architectural style of the single-family homes and the multifamily buildings could be characterized as traditional in form and modern in execution. Simple gable roof forms, two-story bays, and covered entries would be clad in painted cement fiber siding with wood accents, standing seam metal roofs, and large metal-clad wood windows with narrow trim and crisp detailing. Colors would be muted; gray to gray-blue tones—typically with two colors per building, and gray metal roofs. All colors were selected to meet the Town’s reflectivity values.

Wildfire Management
The buildings as proposed would comply with Wildland Urban Interface (WUI) materials and construction methods for exterior wildfire exposure as required per CBC 701A.3, CRC R337.1.3. All buildings would be equipped with an automatic sprinkler system. A defensible space area within 0

-5’ of the building would be noncombustible. A 4”
000335
vertical noncombustible separation zone on the building would be maintained between the siding and the ground plane (or other built horizontal surfaces).

The proposed buildings would be built with WUI materials and comply with construction methods for wildfire exposure, including:
• Roofs of metal or tile.
• Protected vents in eaves or cornices with baffles to block embers. • Eaves and soffits protected with ignition-resistant or non-combustible materials. • Dual-paned windows with one pane of tempered glass to reduce the chance of breakage in a fire. • Walls made of ignition resistant building materials, such as fiber cement, wall siding, fire retardant, treated wood, stucco, or other approved materials.
• Decks (if provided) would be built with ignition-resistant, non-combustible, or other approved materials.

In addition, a Zone 1 wildfire protection area, consisting of irrigated, low-fuel landscaping would be established around the perimeter of the buildings and common open space areas within the development area. A Zone 2 defensible space would be established, where grasses are kept mowed, dead plant material is removed, and space is kept between shrubs, larger trees, and other combustible materials, would be maintained within 200’ of buildings.

Further out, shaded fuel breaks may be used to reduce the fuel load in the surrounding area. The Zone 1 and Zone 2 areas would be owned and maintained by the project homeowner’s association.

As part of the initial review of the project application, the Town of Portola Valley Planning and Building Department routed the application to the Woodside Fire Protection District (WFPD) for review and comment. The WFPD, in review of the application and site plans, required preparation of a Vegetation Management Plan (VMP or plan) to address existing fire hazards across the parcel through fire behavior modeling and to define mitigations to reduce the hazards identified during modeling. On May 5, 2020, Stanford submitted a Vegetation Management Plan to the WFPD and the Town of Portola Valley as a supplement to its application PLN_ARCH0021-2019 for the Stanford University Faculty Housing Project.

In addition, the WFPD requested an access point to be created in approximately the middle of the development between structures. This access point would be a minimum of 12 feet wide access and consist of an all-weather drivable surface to access the undeveloped remainder parcel behind the development for maintenance and emergency vehicle access/egress and defense. The project layout was modified to conform to this requested access.

Project Layout
The project would be configured as shown in the submittal package. Residential units would be constructed on both sides of a new, private loop road that connects at both ends to Alpine Road. This layout is proposed pursuant to a State Density Bonus Law incentive/concession for relief from the development standard in paragraph 2105.4 of the General Plan Land Use Element, to the extent this provision could be read to apply to the proposed project. That paragraph otherwise might be read to require a layout that includes several small, separated clusters of houses, each with substantial direct frontage on common open space.

The project would include common open space areas, which could be used for recreational purposes. These open space areas include areas that front Alpine Road, creating a visual buffer between the road and the project. Aside from the approximately 6 acres of the project site that would be developed, the remainder of the site would be protected from development by an appropriate legal instrument.

The amount of grading, and cut and fill, are shown conceptually in the plan submittal. The project has been designed so that the grading of the site would “balance”, meaning that dirt brought onto or hauled off the site during grading activities would be minimized.

As a provision of the Vegetation Management Plan, Stanford is proposing the construction of a permanent maintenance road. The purpose of this access road is to provide access into presently inaccessible portions of the site to facilitate annual vegetation management of the undeveloped portions of the site for the off-hauling of materials to a composting site. The access road (which can later be used for access by fire personnel in the event of a wildfire) would provide access and staging and would serve as central landing areas to collect material for off hauling.

Trails
As requested by Town of Portola Valley staff, Stanford has proposed trail routes totaling approximately 1.2 miles in length consistent with or equivalent to the potential routes shown on Diagram A of the General Plan’s Trails and Paths Element. The trail routes are:
• Alpine Road Trail
• Portola Terrace Looped Trail
In developing our proposed trail routes, Stanford overlaid the conceptual routes shown in the Trails and Paths Element of the Town’s General Plan (Diagram A) onto a more detailed topographic map of the Stanford property.

Stanford then analyzed this exhibit and made some alterations to the routes to avoid extreme slopes. These variations are consistent with Principle 3210.1.g of the Trails and Paths Element, which states that trails and paths should “disturb the natural conditions of terrain and vegetation as little as possible.” Stanford then made further alterations to the routes to avoid features like potential wetlands and potential riparian corridors, in accordance with State and Federal environmental laws. These variations also are consistent with both Objective 3209.1.i of the Trails and Paths Element, which states that newly created trails should “ensure that such facilities are designed and used so as to avoid habitat degradation,” as well as Principle 3210.1.p, which calls for designing trails “so as to minimize changes in the natural flow of water across the land.” (For a complete explanation of Stanford’s trail proposal, please refer to the letter from Stanford University to Howard Young, Town of Portola Valley Public Works Director dated May 26, 2020, which is also included in our July 2020 submittal package.) Sustainability
In addition to compliance with the new 2019 Building Energy Efficiency Standards, which require zero net electricity development, including solar electricity generation on-site, and compliance with Town of Portola Valley’s “Green Building” code sections, the project would include the following sustainability features that are not required by regulations or ordinances:
• One Level 2 electric vehicle charging station installed in each single-family residence garage. • All-electric construction with no natural gas connections. • Future homes will be offered to Stanford faculty thus creating a strong jobs-to-housing balance on Stanford lands. This reduces vehicle miles traveled and reduces vehicle emissions.

Funding of Private Amenities
A homeowner’s association or similar mechanism would be used to fund maintenance of:
• Common areas near the residences, including open space/recreational areas, landscaping, and stormwater detention/treatment areas;
• Front yards of the homes;
• Private internal loop street;
• Private segments of utilities; and
• Areas designated as fuel management fire protection areas around the perimeter of the homes.

Stanford University would fund maintenance of the natural undeveloped area located further from the residential units and outside the Zone 1 and Zone 2 wildfire protection areas.

Grading
The philosophy behind developing a grading plan for a residential subdivision is rooted in several key principles that prioritize functionality, sustainability, and community well-being. In the case of the Portola Terrace, the project is proposing a cluster subdivision with relatively small homes and lots. While this type of residential home is very commonplace and popular throughout California, Portola Terrace is introducing this type of neighborhood to Portola Valley. The following is the grading philosophy for the Portola Terrace project:

1. Balance and Harmony with Nature

• The project civil engineers must work with the natural contours of the land with the goal of minimizing disruption to the existing landscape. This approach helps maintain natural drainage patterns and preserves the ecological integrity of the site. • Because of the nature of the design of the homes on relatively small lots, the project architect and civil engineer have worked closely together to design a “system wide” grading plan where all lots and adjacent loop street are designed as an integrated package. • Environmental Protection: The civil engineer has identified all existing environmental elements that require attention. In the case of the Portola Terrace site, the project architect and project arborist work with the civil engineer to preserve as many existing trees as possible.

2. Functionality and Usability
• Accessibility: The grading plan must facilitate safe access for vehicles and pedestrians. This includes designing roads, driveways, and walkways that are both functional and aesthetically pleasing while meeting the requirements of the town of Portola Valley and the Woodside Fire Protection District.
• Site Drainage: A critical aspect is ensuring proper drainage to prevent flooding and erosion. The project civil engineer has designed systems that manage stormwater effectively, enhancing both safety and usability.

3. Sustainability
• Resource Efficiency: The grading plan for the site has minimized the need for excessive earthmoving, reducing construction costs and environmental impact. Working with the project’s geotechnical consultants, the civil engineer aims for a balanced cut-and-fill approach to maintain existing soil and reduce waste, and lessen construction emissions and dust. • Long-Term Viability: Sustainable practices, such as incorporating green infrastructure (like bioswales or permeable surfaces), are encouraged to manage water on-site and promote groundwater recharge.

4. Public Safety and Aesthetics
• Attention is given to the visual impact of grading and the long-term safety of residents, ensuring that slopes and grading transitions are gradual and well-defined.

5. Regulatory Compliance
• Adherence to Standards: Engineers must navigate a complex landscape of local regulations, ensuring that their grading plans meet all legal requirements while also serving the community’s best interests.

Relationship between Town Height Requirements and the Planned Unit Development regulations.

The town of Portola Valley measures building height from the natural grade not finished pad elevation, provided a pad is not excavated below natural ground level. Therefore, a building that, in isolation, is 28 feet in height may actually exceed the Town’s 28-foot height limit if you factor in the amount of fill beneath the house. This situation occurs on lots 12, 19, 20, 22/23 (duet unit) 24, 25 and the three BMR structures in the proposed project as depicted on Sheets A0.03 and A0.04 of the application.

The Town’s Zoning Code (section 18.54.030(E)) authorizes exceptions to height requirements as part of an approved planned unit development (PUD). The applicant is requesting that the above height exceptions be granted as part of the PUD. Alternatively, in the event the Town chooses not to grant exceptions through the PUD process, the applicant requests a waiver of the applicable Town height standards under the Density Bonus Law (Gov’t Code section 65915(e)(1)), as application of these standards would have the effect of physically precluding construction of the project.

Infrastructure
As noted, the project would include a new private road that starts on Alpine Road, runs through the developed area, and terminates at another location on Alpine Road. Utilities would be installed underneath the new private road, and then extended to individual residences as necessary.

The project anticipates receiving utility service from the following providers:

• Electricity: Pacific Gas & Electric Company
• Solid Waste & Recycling: GreenWaste Recovery, Inc.
• Water: California Water Services Company
• Sewer: West Bay Sanitary District
The project would construct sewer and water lines from existing mains located in Alpine Road to reach the project site. (In the case of water, a new water line would be extended within Alpine Road to the nearest water connection point as determined by California Water Services Company.) The project would fund or construct such offsite improvements as are needed to create additional capacity to serve the incremental demand of the project.

Stormwater management would be accommodated on site through the use of stormwater detention and bioretention treatment facilities. The project would be designed to meet the stormwater treatment quality standards stated in the C.3 Stormwater Technical Guidance and the stormwater runoff quantity and rates stated in the “Hydromodification Management” guidelines.

Construction
All project construction would occur by or under the direction of Stanford, without custom development of homes.

Depending on when project approvals are obtained, construction is anticipated to commence in spring 2021 and take approximately 24 – 30 months. Site grading activities would take approximately six to eight months, and would utilize equipment that meets BAAQMD Tier Four requirements.

Construction would require removal of 177 (123 listed as “significant” and 54 “non-significant” trees) of the project site’s existing trees as outlined on sheet 3.1 of the Vesting Tentative Map package. (Note: This number may change as the project is reviewed by the Town of Portola Valley.) As part of the construction of the Project, 55 new trees would be planted, as outlined on sheet L3.1 of the Landscape Plans contained on the ASCC submittal package. (Note: This number was reduced from previous submittals based on comments received by Town committees and the WFPD.)

Construiction E~est M~tnagemtent Practices (BMPs)

SAN MATEO COUNTYWIDE
\Nater Polluti1on
Preivention Pro1~ra m
Construction projects are required to implement tlte stormwater best management practices (B:M[P) on this page, as they apply to1 your project, all year long.

Clean Water. Healthy Community.

Materials & VVaste Managemen1t
Non-Hazardons Materials
Benm and cover stockpiles of sand, dirt or other construction material with tarps when rain is forecast or if not actively being used within 14 clays.

Use (but don't overuse) reclaimed water for dust control.

Hazardous Materials
D Label all hazardous materials and hazardous wastes (such as pesticides, paints, thinners, solvents, fuel, oil, and antifreeze) in accordance with city, county, state and federal regulations.

D Store hazardous materials and wastes in water tight containers, store in appropriate secondary containment, and cover them at the end of every work day or during wet weather or when rain is forecast.

Follow manufacturer's application instructions for hazardous materials and be careful not to use more than necessary. Do not apply chemicals outdoors when rain is forecast within 24 hours.

Arrange for appropriate disposal of all hazardous wastes.

Waste Management
Cover waste disposal containers securely with tarps at the end of every work day and during wet weather.

D Check waste disposal containers frequently for leaks and to make sure they are not overfilled. Never hose down a dumpster on the construction site.

D Clean or replace portable toilets, and inspect them frequently for leaks and spills.

Dispose of all wastes and debris properly. Recycle materials and wastes that can be recycled (such as asphalt, concrete, aggregate base materials, wood, gyp board, pipe, etc.)
D Dispose of liquid residues from paints, thinners, solvents, glues, and cleaning fluids as hazardous waste.

Construction Entrances and Perimeter
Establish and maintain effective perimeter controls and stabilize all construction entrances and exits to sufficiently control erosion and sediment discharges from site and tracking off site.

Sweep or vacuum any street tracking immediately and secure sediment source to prevent further tracking. Never hose down streets to clean up tracking.

Equipment Managemelllt &
Spill Control
Maintenance and Parking
D Designate an area, fitted with appropriate Bl\~Ps, for vehicle and equipment parking and storage.

Perform major maintenance, repair jobs, and vehicle
and equipment washing off site.

D If refueling or vehicle maintenance must be done
onsite, work in a bermed area away from storm drains
and over a drip pan or drop cloths big enough to collect fluids. Recycle or dispose of fluids as hazardous waste.

D If vehicle or equipment cleaning must be done onsite, clean with water only in a bermed area that will not
allow rinse wa1ter to run into gutters, streets, storm
drains, or surface waters.

D Do not clean vehicle or equipment onsite using soaps, solvents, degreasers, or steam cleaning equipment.

Spill Prevention and Control
D Keep spill cleanup materials (e.g., rags, absorbents and cat litter) available at the construction site at all times.

Inspect vehicles and equipment frequently for and
repair leaks promptly. Use drip pans to catch leaks
until repairs are made.

Clean up spills or leaks immediately and dispose of
cleanup materiials properly.

D Do not hose down surfaces where fluids have spilled.

Use dry cleanup methods (absorbent materials, cat
litter, and/ or rags).

Sweep up spilled dry materials immediately. Do not
try to wash them away with water, or bury them.

Clean up spills on dirt areas by digging up and
properly disposing of contaminated soil.

Report significant spills inunediately. You are required by law to report all significant releases of hazardous
materials, including oil. To report a spill: 1) Dial 911 or your local emergency response number, 2) Call the
Governor's Office of Emergency Services \Varning
Center, (800) 852-7550 (24 hours).
l~arthmoving
.,-,. ,, ,, ~,1~ '..if(',·•,
Schedule grading and excavation work
during dry weather.

D Stabilize all denuded areas, install and
maintain te:mporary erosion controls (such
as erosion control fabric or bonded fiber
matrix) until vegetation is established.

Remove existing vegetation only when
absolutely necessary, and seed or plant
vegetation :for erosion control on slopes
or where construction is not immediately
planned.

D Prevent sediment from migrating offsite
and protect storm drain inlets, gutters, ditches, and drainage courses by installing and maintaining appropriate BMPs, such as fiber rollls, silt fences, sediment basins, gravel bags, berms, etc.

D Keep excavated soil on site and transfer iit
to dump trucks on site, not in the streets.

Contaminated Soils
If any of the following conditions are
observed, test for contamination and
contact the Regional Water Quality
Control Board:

Unusual soil conditions, discoloration,
or odor.

Abandoned underground tanks. Abandoned wells
Buried barrels, debris, or trash.

Paving/ Asphalt Work
Avoid paving and seal coating in wet weather or when rain is forecast, to prevent materials that have not cured
from contacting stormwater runoff.

Cover storm drain inlets and manholes
when applying seal coat, tack coat, slurry
seal, fog seal, etc.

Collect and recycle or appropriately
dispose of excess abrasive gravel or sand.

Do NOT sweep or wash it into gutters.

Do not use water to wash down fresh
asphalt concrete pavement.

Sawcutting & Asphalt/Concrete Removal
Protect nearby stonn drain inlets when
saw cutting. Use filter fabric, catch basin
inlet filters, or gravel bags to keep slurry
out of the storm drain system.

Shovel, abosorb, or vacuum saw-cut
slurry and dispose of all waste as soon
as you are finished in one location or at
the end of each work day (whichever is
sooner!).

D If sawcut slurry enters a catch basin, clean
it up immediately.
c:oncrete, Grout & Mortar
Application
Store concrete, grout, and mortar away
from storm drains or waterways, and on
pallets under cover to protect them from
rain, runoff, and wind.

Wash out concrete equipmen1Jtrucks
offsite or in a designated washout
area, where the water will flow into a
temporary waste pit, and in a manner
that will prevent leaching into the
underlying soil or onto surrmmding areas.

Let concrete harden and dispose of as
garbage.

When washing exposed aggregate,
prevent washwater from entering storm
drains. Block any inlets and vacuum
gutters, hose washwater onto dirt areas, or
drain onto a bermed surface to be pumped
and disposed of properly.

Protect stockpiled landscaping materials
from wind and rain by storing them under
tarps all year-round.

Stack bagged material on palllets and
under cover.

Discontinue application of any erodible
landscape material within 2 days before a
forecast rain event or during wet weather.

Stor drain pol luters ma be liable or fines o up to $10 000 per d II Painting & Paint Removal
Painting Cleanup and Removal
Never clean brushes or rinse paint
containers into a street, gutter, storm
drain, or stream.

D For water-based paints, paint out brushes
to the extent possible, and rinse into a
drain that goes to the sanitary sewer.

Never pour paint down a storm drain.

D For oil-based paints, paint out brushes to
the extent possible and clean with thinner
or solvent in a proper container. Filter and
reuse thinners and solvents. Dispose of
excess liquids as hazardous waste.

D Paint chips and dust from non-hazardous
dry stripping and sand blasting may be
swept up or collected in plastic drop
cloths and disposed of as trash.

Chemical paint stripping residue and chips
and dust from marine paints or paints
containing lead, mercury, or tributyltin
must be disposed of as hazardous waste.

Lead based paint removal requires a statecertified contractor.

Dewatering
Discharges of groundwater or captured
runoff from dewatering operations must
be properly managed and disposed. When
possible send dewatering discharge to
landscaped area or sanitary sewer. If
discharging to the sanitary sewer call your
local wastewater treatment plant.

D Divert run-on water from offsite away
from all disturbed areas.

D When dewatering, notify and obtain
approval from the local municipality
before discharging water to a street gutter
or storm drain. Filtration or diversion
through a basin, tank, or sediment trap
may be required.

D In areas of known or suspected
contamination, call your local agency to
determine whether the ground water must
be tested. Pumped groundwater may need
to be collected and hauled off-site for treatment and proper disposal.
