RESOLUTION No. 97-06
A RESOLUTION OF THE TOWN COUNCIL OF THE TOWN OF TRUCKEE
APPROVING A MITIGATED NEGATIVE DECLARATION
FOR THE GLENSHIRE DRIVE BRIDGE REPLACEMENT PROJECT
WHEREAS, the Town of Truckee has studied several alignments to replace the Glenshire
Drive bridge over the Truckee River and selected a preferred alignment to analyze the potential
environmental effects which may result from construction of the bridge along the preferred
alignment; and
WHEREAS, the Town prepared an Initial Study pursuant to the California Environmental
Quality Act, identifying the significant environmental effects of the project and the mitigation
measures necessary to eliminate or reduce the significant effects to a less-than-significant level; and
WHEREAS, a Mitigated Negative Declaration was proposed for the project based on the
findings of the Initial Study; and
WHEREAS, notice was provided to the public by publication in the Sierra Sun, a local
newspaper of general circulation, that the Town Council proposed to adopt a Negative Declaration,
and a public review period of 32 days was established from June 13, 1996 to July 15, 1996 for the
Town to receive written comments on the proposed Negative Declaration; and
WHEREAS, the Town Council considered all public comments received during the public
review process prior to approving the Negative Declaration; and
WHEREAS, the Town Council finds the project is subject to the Department ofFish and
Game filing fee for a Negative Declaration.
NOW THEREFORE BE IT RESOLVED BY THE TOWN COUNCIL OF THE
TOWN OF TRUCKEE, AS FOLLOWS:
SECTION 1. The Negative Declaration is on file in the office of the Town Clerk, and
referenced herein, is hereby approved for the Glenshire Drive Bridge Replacement Project. The
following finding is made in approving the Negative Declaration:
The Initial Study identified several potentially significant effects. However, revisions were
made to the project prior to the release of the Negative Declaration for public review which
would avoid the effects or mitigate the effects to a point where clearly no significant effects
would occur. No revisions have been made to the Negative Declaration subsequent to the
public review period, and there is no substantial evidence that the project as revised may
have a significant effect on the environment. This finding is further supported by the
findings contained within the Initial Study.
SECTION 2. The Mitigation Monitoring and Reporting Program attached hereto as Exhibit
"B" and referenced herein is hereby adopted pursuant to Section 21081.6 of the California
Environmental Quality Act.
SECTION 3. The Town Engineer is hereby directed to file a Notice of Determination for
the Negative Declaration with the Nevada County Recorder.
The foregoing Resolution was introduced at a Regular Meeting of the Town Council of the Town
of Truckee, held on the 3rd day of April, 1997, by Councilmembe r Carpenter who moved it's
adoption, which motion duly seconded by Councilmember Florian was upon roll call carried and the
Resolution adopted by the following vote:
AYES: Councilmembers Carpenter, Florian, McCormack, Susman, and Mayor Drake
NOES: None
ABSENT: None

MITIGATION MONITORLNG &ND REPORTING PROGRAM
GLENSlllRE DRIVE BRIDGE REPLACEMENT PROJECT
(BRIDGE NO. 17C-044)
This Mitigation Monitoring and Reporting Program is structured in the following mamaer:
Approving Person/Agency - The person or government agency responsible for
ensuring that the mitigation measure has been implemented and the project complies
with the mitigation measure.
Schedule - The time during the project when the mitigation measure must be
implemented or reviewed for effectiveness.
Town's Responsibilities - Those items which must be addressed or submitted by the
Town as par~ of the monitoring program.
Measure Review - A description of how the approving person/agency will ensure that
the mitigation measure has been implemented.
Enforcement Action - A description of the enforcement mechanisms which will be
utilized if the project does not comply with the mitigation measure.
The Town Engineer is responsible for ensuring that the project complies with all mitigation measures
and that documentation is provided by the "Approving Person/Agency" demonstrating compliance with
the mitigation measure. The "Approving Person/Agency" is responsible for ensuring mitigation
measure compliance and forwarding docmnentation to the Town Engineer upon mitigation measure
compliance. The "Approving Person/Agency" may document mitigation measure compliance by
signing the original mitigation monitoring checklist on file with the Town Engineer; signing a copy of
the mitigation monitoring checklist and forwarding it to the Town Engineer; or forwarding to the Town
Engineer a Ietter staring that the mitigation measure has been complied with.
The Town Engineer will verify that all applicable mitigation measures have been complied with at the
following project time periods:
Preconstruction, i.e., prior to the issuance of any grading or building permits for the
project and prior to the start of construction.
Construction.
Postconstruction.
The Town Engineer is responsible for ensuring that the project complies with all applicable mitigation
measures during its operation.
The Town of Truckee Deparanent of Public Works is responsible for addressing or submitting those
items described for each mitigation measure and complying with the requirements of the mitigation
measure. The Depaxr~nent of Public Works is also responsible for informing people working on the
project under the Town's direction of the requirements of the mitigation measures.
Mitigation measures will be enforced in accordance with the provision of the ordinance or re~m~lations
under which the mitigation measure is being implemented. There are several actions which may be
taken under these ordinances to enforce the mitigation measures, and the type of action taken by the
Mitigation Monitoring Program, Page 2
Town to enforce the mitigation measure will be base on the level of non-compliance and the sensitivity

Mitigation Monitoring Program, Page 4
3. WATER
Impact:
The supports for the temporary falsework, the temporary bridge, and the piers of the new bridge will
be placed within the 100-year floodplain of the Truckee River. The Lahontan RWQCB prohibits
disturbance or the use of fill within this floodplain unless appropriate mitigation is implemented (John
Short, Lahontan RWQCB, pen. comm.). The project measures and the mitigation measures will be
implemented to satisfy the requirements of the Lahontan RWQCB Basin Plan.
Mitigation Measure 3a: Mitigation for the temporary disturbance of the floodplain and riverbed of the
Truckee River will be completed according to the requirements of Lahontan. Typically, this involves
riverbank restoration in the vicinity of the proposed project. Mitigation for the permanent disturbance
of the floodplain (i.e., the footings of the two columns) will also be completed according to the
requirements of Lahontan.
Mitigation Measure 3be The established erosion control regulations of Caltrans, the CDFG, and the
ACOE (e.g., Caltrans Standard Specifications Type D Erosion Control) will be followed during
construction of the proposed project. In addition, the Town of Truckee will adhere to the site-specific
water quality and erosion control measures presented in the permits issued by the ACOE and the
CDFG.
Mitigation Measure 3c: A detailed hydrological study will be prepared for the proposed project. The
effect of the temporary and permanent fixtures of the proposed bridge on the hydrology of the project
area will be discussed in this study, including expected impacts to waterflow and base flood eievation.
While significant hydrological impacts, including flooding impacts, are not expected to result from the
proposed project (Norman Braithwalte, pers. comm.), additional measures suggested as a result of the
findings of the hydrological study will be implemented to mitigate for expected site-specific impacts.
Approving Person/Agency: Town Engineer
Schedule:
a. Preconstruction
b. Construction

g. The Town Engineer will verify that the additional measures, if necessary, are
implemented.
4. AIR QUALITY
Impact: Short-term increases in PMto will occur during project construction (i.e., during the summer
to fall construction period in 1997 and 1998), as dust is created by construction vehicles and
equipment.
Mitigation Measure 4ac Open burning of vegetation cleared from the project area will be
conditionally prohibited. Cleared vegetation shall be treated by legal means other than open burning,
including chipping, sbxedding, or grinding. Open burning of cleared vegetation will be permitted only
upon NSAQMD acceptance of documentation showing that alternatives are not possible or
economically feasible. At no time shall materials generated by the proposed project be burned at
another site, unless such action is approved in advance by the NSAQMD.
Mitigation Measure 4b: Fugitive dust emissions resulting from clearing and other construction
activities shall be minimized at all times to the satisfaction of the APCO. Measures such as the use of
dust palliatives or the regular application of water shall be applied to minimize dust emissions. Access
or haul roads to the project area will be treated as necessary to prevent offsite migration and
accumulation of di~., soils, or other materials which could result in increased levels of PM~o.
Mitigation Measure '4c: When transporting materials during site preparation or construction,
measures shall be implemented to prevent materials from spilling or blowing onto streets and highways.
Earthen materials shall be adequately sprayed with water prior to transport onto public roads. If
requested by the NSAQMD, a dust control plan shall be prepared and approved prior to the initiation
of ;ire preparation and construction.
Approving Person/Agency: Town Engineer, APCO.
Schedule:
a. Preconstruction
b. Construction
Mitigation Monitoring Program, Page 6
Town's Responsibilities:
Co
During construction, the Town will dispose of graded vegetation by other means than
by burning.
In accordance with Mitigation Measure 2a, the Town shall submit to the NSAQMD a
letter indicating specific dust control measures to be employed on-site for the duration
of site preparation and construction. Dust controls may include applications of
regularly applied water using mobile water trucks or sprinklers, graveling or paving
haul roads, using truck load covers, using mud gates at site exits, or using chemical
palliatives for soil treatments. These or other dust control methods will be utilized
when and where necessary, to the satisfaction of the APCO, in order to prevent on-ske
fugitive dust emissions, or off-site migration of fugitive dust or entrained soils. This
letter must be submitted by the Town at least 30 days prior to initiation of site
preparation, with subsequent approval by the NSAQMD prior to construction starmp.
The Town Engineer will verify that the APCO has approved the method of vegetation
disposal and the requirements of the NSAQMD have been met.
The Town Engineer will verify that the APCO has approved the method of controlling
fugitive dust emissions and the requirements of the NSAQMD are incorporated into the
grading plan.
If required, the Town will prepare a dust control plan for approval by the APCO.
The Town will prevent spilling as directed above.
Measure Re,dew:
The Town Engineer shall verify that a dust control plan, if necessary, has been
prepared and approved by the APCO.
The Town Engineer shall verify that spilling is prevented during construction.
6, BIOLOGICAL RESOURCES
Impact: The temporary loss of approximately 9,420 m2 and the permanent loss of approximately
13,480 m2 of vegetative communities, including wildlife habitat, will result from the proposed project.
Because revegetafion measures, including replanting of trees, will be implemented as part of the
proposed project, the loss of wildlife habitat will be mitigated to a less than significant level.
Mitigation Measure 6a: During construction, care will be taken to limit the amount of disturbance to
riparian habitat. Disturbance to the Truckee River and surrounding habitat will be limited to the extent
feasible (thereby lessening the potential for impacts to special-status amphibian, reptile, bird, and
mammal species). Erosion control measures (i.e., Caltrans Standard Specifications Type D Erosion
Control) will be implemented during construction to limit siltation in the river and impacts to other
special-status species habitat within the project area.
Mitigation Measure 6b: As required and directed by the USFS, construction of the proposed project
will comply with the applicable management requirements and constraints of the Tahoe National Forest
Land and Resource Management Plan Riparian Area Management Guideline #46 and the Guidelines for
Management in Riparian Areas and Streamside Management Zones (Appendix F, Guideline A-i; USFS
1990; Rick Maddalena, Tahoe National Forest, pers. comm.). Impacts to riparian vegetation will be
limited during construction, and revegetation of this habitat so as to replace the riparian functions and
Mitigation Monitoring Program, Page
values lost will be completed. Erosion control measures will be implemented to limit impacts to the
Truckee River and its fisheries.
Mitigation Measure 6c: To prevent construction impac:s to nesting cliff swallows, exclusionary
nemng will be hung from the existing bridge in early March of the year the bridge is to be demolished.
Exclusionary, herring will not be necessary if the bridge is demolished between November and January,
since swallows will not be present within the project area during that time and impacts are not
expected. The proposed bridge will provide nest sites for swallows once the existing bridge is
removed.
Mitigation Measure 6d: As required by the CDFG as part of the 1601 Streambed Alteration
Agreement, by the USFWS as part of the ACOE 404 Permit, and by the Town of Truckee's General
Plan Conservation and Open Space Policies 1.3 and 1.4, the fiparian habitat that is temporarily
disturbed during construction and the approximately 40 m2 of riparian community that will be
permanently lost as a result of the proposed project will be revegetated. The approximately 40 m2 of
riparian community, will be replaced in kind within the existing fight-of-way at a 3: I ratio (i.e.,
approximately 120 m: or 0.03 acres) so as to replace the riparian functions and values lost (Jeff Finn,
CDFG, pets. corem; Mark Littlefietd, USFWS, pers. comm.). This replacement will result in no net
loss of riparian vegetation. The Town will plant the appropriate numbers and species of trees and
shrubs so that the mitigation area will resemble the project area prior to disturbance. Material that
cannot be feasibly collected onsite will be obtained from a nursery source. The mitigation area will be
actively irrigated for the first and second summers after planting, reducing the amount of irrigation by
one half in the third summer, and ceasing the irrigation in the fourth summer. A ten year monitoring
program will be completed, with intensive monitoring during the ~st three years, then less intensive
monitoring in years five, eight, and I0. The Town will adhere to the success criteria established by
the CDFG and the USFWS for the mitigation area, including replanting, as necessary.
Approving Person/Agency: Town Engineer, USFS, ACOE, CDFG.
Schedule:
a. Construction
b. Postconstruction
Town's Responsibilities:
The limits of construction within riparian areas and within the Truckee River will be
clearly marked on construction drawings and, where possible, with construction
reno;rog. Construction workers will be made aware of requirements to limit
construction activities to designated areas. Erosion control measures will be
implemented in accordance with Mitigation Measures 2a, 2b, 2c, and 3b.
Impacts to riparian vegetation will be limited in accordance with Mitigation Measure
6a. Erosion control measures will be implemented in accordance with Mitigation
Measures 2a, 2b, 2c, and 3b.
Revegetation of riparian areas will be completed in accordance with Mitigar2oa
Measure 6d.
If demolition occurs outside the November to lanuary window, the Town shall hang
exclusionary netting from the eMsting bridge in early March of the year of demolition.
After construction is complete, the Town shall complete replanting, irrigation, and
monitoring as discussed above. Monitoring shall be completed by a qualified
representative of the Town and reports completed during years one through three, five,
Mitigation Monitoring Program, Page
eight, and 10. These reports shall be fi/ed with the CDFG and the USF'WS. If the
revegetation efforts do not ad_here to agency success criteria, the Town shall implement
necessary remedies as directed by the USFWS and the CDFG.
Measure Review:
During regular inspections of the construction site, the Town Engineer will verify that
construction activities are limited to designated areas.
The Town Engineer will verify that the USFS is satisfied with the measures being
implemented.
The Town Engineer shall verify that the exclusionary netting is in place in early March
of the year of demolition.
The Town Engineer shall verify that revegetation, irrigation, and monitoring efforts
have been completed at the necessary intervals and that the ACOE and CDFG are
satisfied with the revegetation efforts.
13. CULTURAL RESOURCES
Impact: The charcoal oven within the project area is typical of many other ovens that have been
inventoried in the region. The proposed project has the potential to impact this oven, however, with
the implementation of the mitigation measure discussed below, these impacts are expected to be less
than significant.
While the prehistoric lithic scatter within the project area is sparse and has been greatly disturbed,
therefore is not eligible for listing on the NRHP, it is located within an are." '~ith the potential to
contain other prehistoric sites. The proposed project could impact this are= however archaeological
monitoring during construction will render these impacts less than significant (see mitigation measures
below).
Mitigation Measure 13a: If artifacts (paleontological or archaeological) or unusual mounts of stone,
bone, or shell are uncovered during construction activity, construction work shall be halted and a
qualified archaeologist shall be consulted for an onsite review. Mitigation measures, as recommended
by the archaeologist and approved by the Community Development Director in accordance with
Appendix K of the CEQA Guidelines, shall be implemented prior to recornmencement of construction
activities. If any bone appears to be of human origin, the Nevada County Coroner and the Native
American Heritage Commission will be contacted.
Mitigation MeasUre 13b: Trenching or grading in the area of the bulldozed refuse deposit and the
prehistoric lithic scatter will be monitored by an archaeologist. If artifacts or other resources are
found, construction work shall be halted and appropriate mitigation implemented.
Mitigation .Measure 13c: A sample of charred wood present on the charcoal surface oven will be
retrieved for dendrochronological dating. The oven itself need not remain in place, since numerous
similar ovens are present within the project vicinity. However, none of these ovens has been precisely
dated and knowledge of their period of use is imprecise.
