Final Mitigation Monitoring and Reporting Program (MMRP)

Los Angeles Harbor Department Section 2 Mitigation Monitoring and Reporting Program
MM BIO-1b: Bat Roosting Habitat Timing: Prior to Project construction (focused
biological surveys of bats), during Project construction
(2013-2015), and after Project construction (postconstruction
survey of bats)
The following activities shall be required with regard to bat
roosting habitat:
a. Prior to construction, a qualified biologist shall conduct
three focused bat surveys between March and November to
conclude presence/absence of roosting bats within Pacific
Coast Highway Bridge and Dominguez Channel Bridge. A
pre-construction survey for roosting bats shall be performed
within 30 days prior to removal of palms within the BSA. If
no active roosts are found, then no further action will be
needed. If either a maternity roost or hibernacula (structures
used by bats for hibernation) is present, the measures below
will be implemented to avoid and reduce impacts to roosting
bats;
b. Prior to the anticipated bat roosting season (March to
November) exclusionary devices will be installed. Installation
of these devices will be completed prior to February 1
(beginning of bird breeding season) and will remain until
construction is completed. A pre-clearance survey will be
conducted at least one day prior to installing exclusionary
devices to determine if bats are present. Exclusionary devices
installed will include plastic sheeting, plastic or wire mesh,
expanding foam, or plywood sheets. A pre-construction
survey will also be completed at least one week prior to
construction to verify exclusionary devices are successful and
no bats are present. If bats are detected, an agency-approved
bat biologist will be consulted to discuss additional measures
to exclude bats.
c. If active maternity roosts or hibernacula are found in
trees or structures to be removed or renovated as part of
project construction, the project should be redesigned to avoid
the loss of the occupied roost if it is possible to do so. If an
active maternity roost is located and the project cannot be
redesigned to avoid removal of the occupied palm or
structure, demolition should commence before maternity
colonies form (i.e., prior to March 1) or after young are flying,
Methods: This measure shall be incorporated into the
BNSF’s bid and contract specifications approved by
LAHD for all construction work to ensure contractor(s)
are aware of potential work area limitations. The
contractor(s) shall adhere to these specifications
throughout construction activities. Biologists will
survey site for active bird nests of native bird species,
and for roosting bats. If nests and/or roosting bats are
present, a protection barrier or protection zone, as
described in the MMBIO-1a and MM BIO-1b, shall be
established, and construction will avoid those sites. The
protection barrier or zone will remain until a qualified
biologist determines that the young have fledged or the
nest or roosting is no longer active. Enforcement shall
include oversight by BNSF’s project/construction
managers.
