Standard Measures: The City would implement the
following best management practices as recommend
by BAAQMD for all projects during construction to
reduce dust impacts:
• All exposed surfaces (e.g., parking areas, staging
areas, soil piles, graded areas, and unpaved access
roads) shall be watered two times per day.
• All haul trucks transporting soil, sand, or other
loose material off-site shall be covered.
• All visible mud or dirt track-out onto adjacent
public roads shall be removed using wet power
vacuum street sweepers at least once per day. The
use of dry power sweeping is prohibited.
• All vehicle speeds on unpaved roads shall be
limited to 15 mph.
• All roadways, driveways, and sidewalks to be
paved shall be completed as soon as possible.
Building pads shall be laid as soon as possible
after grading unless seeding or soil binders are
used.
The City and
contractors shall be
responsible for
implementing this
standard measure
during all phases of
construction.
This standard
measure shall be
printed on all

prot
ected tree shall be securely fenced off at the
“protected perimeter,” which shall be either the
drip line or other limit as may be established by

measures shall be utilized, as approved by the
Director, to allow the roots to obtain oxygen,
water, and nutrients as needed. Any excavation,
cutting, filling, or compaction of the existing
ground surface within the protected perimeter, if
authorized at all by the Director, shall be
minimized and subject to such conditions as may
be imposed by the Director. No significant change
in existing ground level shall be made within the
drip line of a protected tree. No burning or use of
equipment with an open flame shall occur near or
within the protected perimeter. All brush, earth
and other debris shall be removed in a manner
which prevents injury to the protected tree.
• No oil, gas, chemicals or other substances that
may be harmful to trees shall be stored or dumped
w
ithin the protected perimeter of any protected
t
ree, or at any other location on the site from
which such substances might enter the perimeter
of a
protected tree. No construction materials shall
be stored within the protected perimeter of a
protected tree.

tunnels shall be made below the roots. Trenches
shall be consolidated to service as many units as
possible. Trenching within the drip line of
protected trees shall be avoided to the greatest
extent possible and shall only be done under the
on-site directions of a Certified Arborist.
• No concrete or asphalt paving shall be placed
within the dripline of protected trees [selected for
preservation]. No artificial irrigation shall occur
within the root zone of oaks.
• No compaction of the soil within the root zone of
protected trees [selected for preservation] shall
occur.
The Tree Ordinance also allows the Director to impose
additional conditions for work encroaching on the
protected perimeter of a protected tree. Where
construction activities overlap with heritage tree
dripline the following protection measures will be
required as conditions of approval:
• A Tree Protection Zone (TPZ) equal to the
dripline radius plus 10 feet shall be the standard

which ground disturbance shall be limited to the
maximum extent feasible.
• Where possible, temporary protective fencing
shall be installed around the TPZ of each tree
designated for preservation prior to
commencement of any construction activity
conducted within 25 feet of the TPZ, of a tree
designated for preservation.
• Many existing trees in the project area selected for
preservation are situated too close to project
improvements (e.g., trail alignments), where
fencing around the TPZ is infeasible. In those
cases, high visibility temporary fencing shall be
wrapped around the tree trunk to signify the tree is
to be saved and to alert machine operators to
avoid damaging the tree. Extreme caution shall be
taken to avoid mechanical injury to tree trunks,
scaffold branches and root flares. As soon as
required work is complete within the TPZ,
temporary protective fencing shall be installed
around the TPZ and shall remain in place as long
as ground disturbance activities are taking place.

• The fence shall consist of highly visible material
(e.g., orange safety fencing) to prevent inadvertent
encroachment by heavy machinery. Heavy
equipment use, excavation, fill, grading,
trenching, drainage changes or other soil
disturbance shall be limited within the TPZ.
Material storage, vehicle parking, and trash
disposal shall not occur within the TPZ.
• Grading and soil compacting shall be restricted
within the TPZ to the maximum extent feasible. If
any significant roots (2-inch diameter or greater)
are uncovered within the TPZ they shall be kept
moist at all times with use of damp burlap fabric,
and buried as soon as feasible.
• Grading and/or trail construction within the TPZ
of heritage trees shall be monitored periodically
by a Certified Arborist. All necessary tree work
should be performed by an ISA-Certified Arborist
or comparable tree specialist. Improper pruning
can be harmful to health and structure of trees. No
tree pruning will be permitted unless approved by
a Certified Arborist. Any pruning of existing trees
shall be performed by a licensed tree care
professional and shall comply with the ANSI

cleaned prior to and after use. All branches being
removed shall be cut to, but not beyond, the

that maintains the balance and structure of the

• Site drainage should be designed to create positive
drainage away from the trunk of preserved trees,
and to prevent ponding within the TPZ.

is planned March 1 through April 14, or September
1 through October 14 (outside the winter
hibernation, and bat maternity roosting season), a
qualified biologist should implement passive
exclusion measures to prevent bats from re-
entering the structures. After sufficient time to
allow bats to escape and a follow-up survey to
determine if bats have vacated the roost,
demolition may continue and impacts to special-
status bat species will be avoided. For tree removal
that occurs during this time, trees should be felled
in a two-step method as follows:
o Remove limbs of trees first and leave them
unprocessed on the site for at least 24 hours.
o After the 24 hour period passes, the remainder
of the tree can be felled and debris can be

disturbance. The biological monitor will conduct a
training session for all construction workers before
work is started on the project. If any CTS are
encountered during ground disturbing activities, all

ornithologist, in consultation with CDFW, will
determine the extent of a construction-free buffer zone to be established around the nest, typically 50 to 250
feet with the lesser distance for smaller passerine birds and the greater distance for raptors, to ensure that
raptor or migratory bird nests will not be disturbed
during project construction. Project activities may

incorporate, but would not be limited to, the following best management practices:
• Maximize the physical separation between noise
generators and noise receptors. Such separation
includes, but is not limited to, the following
measures:
o Locate stationary equipment to minimize noise
impacts on the community;
o Minimize backing movements of equipment;
• Construct temporary noise barriers, where feasible,
to screen noise-generating equipment. Temporary
noise barrier fences would provide a five dBA
noise reduction where the noise barrier interrupts
the line-of-sight between the noise source and
receptor when constructed in a manner that
eliminates any cracks or gaps.
• Use quiet construction equipment whenever
