Impact 4.8.1 Implementation of the proposed project
could result in direct and indirect loss of
habitat and individuals of endangered,
threatened, rare, proposed, and candidate
status, as well as plant species identified
by the California Native Plant Society with
a rating of List 1A or 1B (i.e., rare,
threatened, or endangered plants).
PS MM 4.8.1a If ground-disturbing activities and vegetation
removal are scheduled to occur within two years of
the currently valid rare plant surveys (June 2011),
no additional rare plant surveys are required. If the
rare plant surveys are no longer valid due to a lapse
in time of project construction commencement
(including phasing), rare plant surveys are
warranted as follows: Prior to any vegetation
removal or ground-disturbing activities for each
phase of development, focused rare plant surveys
shall be conducted to determine the presence of
special-status plant species with potential to occur
in the impact areas. Surveys shall be conducted in
accordance with Guidelines for Assessing the
Effects of Proposed Projects on Rare, Threatened,
and Endangered Plants and Natural Communities
(CDFG, 2000). These guidelines require rare plant
surveys to be conducted at the proper time of year
when rare or endangered species are both
“evident” and identifiable. Field surveys shall be
scheduled to coincide with known blooming
periods and/or during periods of physiological
development that are necessary to identify the plant
species of concern. If no special-status plant species
are found, then the project will not have any impacts
to the species and no additional mitigation measures
are necessary.
If special-status plant species are located within
temporary impact areas, then additional mitigation
is necessary (see below). If any of the species are

known locations of Donner Pass buckwheat), the
Town shall consult with the USFWS and/or CDFG,
as applicable, to determine appropriate avoidance
and mitigation for special-status plants, which may
include, but is not limited to the following
measures:
If special-status plants are identified and will not be
directly impacted, protective fencing would be
required to ensure that the plant or plants are not
destroyed, crushed, or damaged during
construction. A buffer zone will be established and
the area will be fenced off. Signs will be posted to
publicize the sensitive nature of the area.
For special-status plants that will be directly
impacted, efforts shall be made to salvage portions
of the habitat or plant populations that will be lost
as a result of implementation of the proposed
project by transplanting the plants that would be
adversely affected by the proposed project for
planting in a new area in appropriate habitat. The
transplantation area will be located in an area that
would support that species and be preserved in
perpetuity. A propagation program shall be
developed for the salvage and transfer of rare,
threatened, or endangered plant populations from
the site before the initiation of construction
activities. Permits may be required from the CDFG
or USFWS, which will ensure that certified
biologists are involved in the propagation and
transport of rare, threatened, or endangered plant
species. (Note: Propagation methods for the
salvaged plant population must be developed on a
case-by-case basis and must include the
involvement of local conservation

If an active nest is located during pre-construction
surveys, USFWS and/or CDFG (as appropriate)
shall be notified regarding the status of the nest.
Furthermore, construction activities shall be
restricted as necessary to avoid disturbance of the
nest until it is abandoned or the biologist deems
disturbance potential to be minimal. Restrictions
may include establishment of exclusion zones (no
ingress of personnel or equipment at a minimum
radius of 500 feet around an active bald eagle or
osprey nest, 250 feet around an active other raptor
nest, and 100 feet around an active migratory bird
nest) or alteration of the construction schedule.

•
Prior to any ground disturbances or construction
within 20 feet of the archaeological site CA-NEV-
785, the following mitigation shall be
accomplished:
•
All land disturbance and construction shall
avoid site CA-NEV-785 and a buffer area of 20
feet around the perimeter of the site shall be
established.
•
A Historic Properties Treatment Plan shall be
completed using the Archaeological Testing
and Data Recovery Approach outlined in the
Archaeological Inventory Survey prepared for
the proposed project (Genesis Society, 2013)
which is included as Section 4.9.5 of the Draft
EIR.

Prior to initiation of ground-disturbing
activities, formal archaeological testing of the
prehistoric site shall be completed as well as
evaluation of the significance of any cultural
materials encountered during any formal
archeological testing in accordance with the
recovery methods and analytical techniques
and approaches described in the

• Upon completion of formal archaeological
testing or any mitigative-level data recovery
excavations recommended on the basis of
testing results, initial ground-disturbing
impacts to untested portions of the prehistoric
site shall be monitored per the specifics
identified in the Monitoring Plan of the
Archaeological Inventory Survey, included in
Section 4.9.5 of the Draft EIR. Monitoring
shall ensure that any inadvertent discoveries
of previously undocumented and unknown
cultural materials encountered are evaluated
and that an appropriate level of data recovery
is undertaken in the event of such a discovery.
Monitoring shall involve one or more
archaeologists (depending on the number of
pieces of equipment operating at once) during
initial land clearing, grading, and other
ground-disturbing impacts at the site or within
the 20-foot buffer and shall include the
presence of a Native American representative.
Timing/Implementation: As a condition of project approval, and
implemented during project
construction for each phase
Monitoring/Enforcement: Town of Truckee Planning Division
MM 4.9.2b If, during the course of construction, cultural
resources (i.e., prehistoric sites, historic sites, exotic
rock [non-native], or unusual amounts of shell or
bone, isolated artifacts, or other features) are
discovered, work shall be halted immediately within

Truckee Community Development Department shall
be notified, and a professional archaeologist that
meets the Secretary of the Interior’s Professional
Qualifications Standards in prehistoric or historical
archaeology shall be retained to determine the
significance of the discovery. Determination of
impacts, significance, and mitigation shall be made
by a qualified archaeologist (in consultation with
recognized local Native American groups, if the
resources are of Native American association). Prior
to the commencement of project excavations, all
construction personnel shall be informed of the
potential to inadvertently uncover cultural resources
and human remains and the procedures to follow
subsequent to an inadvertent discovery of cultural
resources or human remains.

Impact 4.9.3 Approval of the proposed Coldstream
Specific Plan could result in the potential
disturbance of paleontological resources
(i.e., fossils and fossil formations) on the
project site.
PS MM 4.9.3 A note shall be placed on the improvement plans
stipulating that if paleontological resources are
discovered on-site, the applicant shall retain a
qualified paleontologist to observe grading
activities and salvage fossils as necessary. The
paleontologist shall establish procedures for
paleontological resource surveillance and shall
establish, in cooperation with the project
developer, procedures for temporarily halting or
redirecting work to permit sampling, identification,
and evaluation of fossils. If major paleontological
resources are discovered, which require
temporarily halting or redirecting of grading, the
paleontologist shall report such findings to the
