On January 15, 2008, the San Luis Obispo County Board of Supervisors approved a
Memorandum of Understanding (MOU) between the San Luis Obispo County Flood
Control and Water Conservation District, Zone 3 and Central Coast Salmon
Enhancement (CCSE) to replace the Arroyo Grande stream gauge, which measures
water surface level elevations and flow (see Attachment 1 for MOU). The stream gauge
is a migration barrier for steelhead trout, which is listed as an endangered species by
the federal government. Given the numerous studies required to implement the stream
gauge fish passage improvement project and limited funding opportunities, it took
several years to assemble all of the project components. Funding to implement the
project occurred through the 2014 Fisheries Restoration Grant Program (FRGP)
administered by the California Department of Fish and Wildlife (CDFW).
FRGP was established in 1981 in response to rapidly declining populations of wild
salmon and steelhead trout and deteriorating fish habitat in California. This competitive
grant program has invested millions of dollars to support projects from sediment
reduction to watershed education throughout coastal California. Contributing partners
include federal and local governments, tribes, water districts, fisheries organizations,
watershed restoration groups, the California Conservation Corps, AmeriCorps, and
private landowners.
CCSE is a small, local non-profit organization formed to help communities strengthen,
protect and understand their watersheds and fisheries through education and
engagement. CCSE applied for and received funding through FRGP to implement the
project.
Proiect Description
CCSE DroDoses to modifv an existing broad-crested concrete weir spanning the width of . .
the main stem of ~rroyb Grande Creek (see Attachment 2 for photos). The weir,
combined with a stream gauge, was once used by the United States Geological Survey
(USGS) as a gauging station and is still currently in use by the County of San Luis
Obispo. The gauge consists of a tower structure, stream gauge equipment, stairs down
to the creek from the top of the bank and a concrete platform across the creek channel.
The work site is about thirty-five feet (35') below the top of the bank.
The project will lower this weir to restore reliable access to 3.3 miles of critical steelhead
habitat upstream of the barrier. The barrier modification will provide passage for both
adult and juvenile steelhead trout at both low and high flows by notching the weir to
lower the jump height and reduce velocity. Technical details of passage and flow
conditions resulting from the proposed project have been vetted by an experienced
team of biologists, engineers and other scientists from a range of public agencies, non-
profits, and private firms.
The project will involve accessing the site from Myrtle Street. A crane will be utilized to
lower heavy machinery into the creek and remove demolished concrete. The staging

area for the heavy machinery is at the top of the bank immediately upstream of the
gauge. An access path for manual movement of material into and out of the creek will
be created adjacent to the staging area. The new weir will be poured using a quick set
concrete that requires about 24 hours of cure time.
There may also be issues with the rock slope on the south bank, which may not be
keyed into the channel bed. If the rock slope is not keyed in, it could be affected when
the stream channel naturally adjusts to the new weir elevation during winter flows. To
prevent any impacts to the rip rapped slope, an exploration trench at the toe of the
existing rip rapped slope is proposed to confirm the depth of the existing embedment.
After inspection by the engineer, the contractor will either backfill and compact the
trench or extend the trench along the entire base of the existing rip rapped slope and
backfill with four (4) ton rock.
A concrete grade control structure will also be built to prevent channel incision upstream
of the project site. The grade control structure will be constructed using the quick set
concrete mentioned above. Water will be diverted around the project site during
construction and concrete cure time. Construction is tentatively scheduled to
commence in June or July of 2016.
Specific construction activities of the project include: establishing access and equipment
staging areas; installing Best Management Practices (BMPs) for stormwater
management; installing and removing water diversion; clearing and grubbing the site;
removing debris; demolishing weir concrete; excavating bedrock and native soil;
building forms and pouring concrete to build concrete weir and grade control; and re-
vegetating disturbed areas of the project site. Because this is a State grant, there will
be consistent and thorough pre- and post-construction monitoring and reporting (see
Exhibit D of the Resolution for Technical Specifications and Attachment 3 for an outline
of specific project tasks).
Staff Advisory Committee (SAC)
The SAC considered this project on May 27, 2015. Issues discussed included:
requirement for an encroachment permit for access from Myrtle Street; construction and
generator noise impacts to the surrounding neighborhood; expanded neighborhood
notification about the project; impacts to existing trees and riparian vegetation during
construction; requirement of a stormwater pollution prevention plan (SWPPP) and
erosion control plan; requirement to provide additional information concerning creek
bypass including any pumping requirements, pump hours of operation, who to call with
noise complaints, the size of the pump; requirement to restore site access area to pre-
construction condition; coordinate project work with the County Flood Control District;
and permitting must be accomplished with all agencies involved including the US Army
Corps, State Department of Fish and Wildlife, State Water Board, Flood Control District,
etc.

ANALYSIS OF ISSUES:
Conditions of Approval
Per SAC comments and subsequent clarification of issues with the applicant, project
concerns have either been resolved or met through conditions of approval:
e The applicant is conditioned to obtain an encroachment permit.
e Noise impacts - water from the creek will be re-routed around the work area by
using a sump pump. A generator will be required to continuously pump creek
water for 24 hours per day for about twenty (20) days. To reduce noise impacts
to the surrounding neighborhood and as conditioned, noise control curtains shall
be used around the generator to ensure that the noise levels do not exceed 45
decibels per Municipal Code Section 9.16.040 (Exterior noise level standards).
Neighborhood notification - the applicant sent a letter and left door hangers
earlier this year to surrounding residents informing them about the project and
inviting them to a meeting to discuss potential issues. According to the applicant,
only residents from one household attended the meeting. It was anticipated at
the time that work would commence in July 2015. Because project construction
has been postponed until next year, a condition has been added to require the
applicant to notify all neighbors located within a 500' radius of the project area at
least thirty (30) days prior to earthmoving activities.
Other agency permits - All required State and Federal agency permits have been
obtained, except for the Streambed Alteration Permit pursuant to Fish and Game
Code Section 1600. The project is conditioned to obtain all necessary agency
permits prior to commencing earthmoving operations.
Impacts to biological resources -The project does not include any tree removal,
although trimming of several willow trees will be necessary. The project will also
involve grubbing, which will require removal of some riparian vegetation. A
vegetation restoration plan has been submitted (see Exhibit F of the Resolution).
Mitigation monitoring will occur throughout the project construction to protect any
potential threatened or endangered plant or animal species (see Exhibit
e Stormwater Control Measures - The project is conditioned to prepare a
Stormwater Pollution Prevention PlanIErosion Control Plan prior to the
commencement of any earthmoving activities.
Creek water bypass - As a condition of approval, the applicant is required to
provide additional information concerning pumping requirements, pumping hours
of operation, who to call with noise complaints, and the size of the pump.

Fence - the fence located off of Myrtle Street where access to the site will occur
will be temporarily removed to allow a crane and heavy equipment into and out of
the project site. The fence will be replaced when the work is complete.
0 The County Flood District has approved the project per a Resolution from the
Board of Supervisors (Attachment 3).
It should be noted that the project and water bypass will not restrict flow
downstream.
General Plan Consistency
The Project is consistent with General Plan Objective ClOS2, which states: "Safeguard
important environmental and sensitive biological resources contributing to healthy,
functioning ecosystems." The Project is also consistent with General Plan
Implementing Policy CIOS2-1.6: "Plan, design, and develop sites to: Protect scenic
resources, water quality and natural creekside habitat, including opportunities for wildlife
habitation, rest, and movement. Further the restoration of damaged or degraded
habitat, especially where a continuous riparian habitat corridor can be established."
The project serves the public purpose of furthering the preservation of steelhead trout
and other deteriorating fish habitat. CCSE is a non-profit and a waiver of the application
fee will allow CCSE to implement the Stream Gauge Passage lmprovement Project.
ALTERNATIVES:
The following alternatives are presented for Planning Commission consideration:
1. Adopt the attached Resolution approving Conditional Use Permit 15-001;
2. Do not adopt the attached Resolution; or
3. Provide direction to staff.
ADVANTAGES:
Approving the Stream Gauge Fish Passage lmprovement project will restore reliable
access to 3.3 miles of critical habitat upstream of the stream gauge for steelhead trout,
listed as an endangered species.
DISADVANTAGES:
Approving the project will expose the surrounding neighborhood to construction and
generator noise. However, the generator noise will be reduced to allowable night time
decibel levels with noise control curtains, construction hours will be limited as
conditioned, and the noise exposure will be temporary (approximately 20 days from
project commencement).

The Project: This project uses grant funds approved by the California
Legislature to initiate activities that are designed to restore salmon and steelhead
habitat in coastal streams and watersheds. Years of poor land management within
California's watersheds which combined with natural events has altered native
habitats. This has limited the ability of fish to survive and successfully reproduce in
coastal streams that historically produced large populations of salmon and
steelhead. This proposed project is designed to increase populations of wild
anadromous fish in coastal streams by restoring their habitat.
The project objective is to improve spawning success for adult salmon and
steelhead as well as to increase survival for eggs, embryos, and rearing juvenile
salmonids. Bank erosion and riparian enhancement treatments improve spawning
conditions and embryo survival by reducing sediment yield to streams. Upslope road
decommissioning or upgrading also help address these widespread problems. The
replacement of migration barriers at stream crossings with bridges or natural stream
bottom culverts allow adult and juvenile salmonids access to additional spawning and
rearing habitats. The installation of instream habitat improvement structures recruit
and sort spawning gravel for adult salmon and steelhead, and create summer rearing
pool and over-wintering habitat for juveniles.
The Finding: Although the project may have the potential to cause minor
short-term impacts on soil, vegetation, wildlife, water quality, and aquatic life, the
measures that shall be incorporated into the project will lessen such impacts to an
insignificant level (see initial study and environmental checklist).
Basis for the Finding: Based on the initial study, it was determined there
would be no significant adverse environmental effects resulting from implementing
the proposed project. In addition, the project is expected to achieve a net benefit to
the environment by enhancing and maintaining quality salmonid spawning and
rearing habitat in the twelve-county project area.
The California Department of Fish and Wildlife (CDFW) finds that
implementing the proposed project will have no significant environmental impact.
Therefore, this mitigated negative declaration is filed pursuant to the California
Environmental Quality Act (CEQA), Public Resources Code Section 21080 (c2). This
proposed mitigated negative declaration consists of all of the following:

INTRODUCTION
The 2014 Fisheries Restoration Grant Program (FRGP) in Del Norte,
Humboldt, Los Angeles, Marin, Mendocino, San Luis Obispo, San Mateo, Santa
Barbara, Santa Cruz, Siskiyou, Sonoma, and Ventura counties is a "project" subject
to review under the California Environmental Quality Act (CEQA) (Pub. Resources
Code, $j 21000 et seq.). The FRGP involves funding, in whole or in part, of 90
habitat restoration items. These 90 restoration items are divided into 45 action items
and 45 non-physical items.
The 45 action items, which are discussed in detail in the environmental
analysis that follows (listed in Appendix A, Action Items) are the principal focus of the
environmental analysis set forth below.
The 45 non-physical habitat restoration-related activities are exempt from
CEQA and are implemented within various counties of the CDFW FRGP region.
These action items will not have a significant effect on the existing environment, and
involve the award of grants for projects such as watershed evaluation, assessment,
project planning, technical training, monitoring, and public involvement. Each of
these exempt action items are identified in Appendix A, Exempt Items.
This initial study and the mitigated negative declaration (MND) analyze the
environmental impacts that might result from implementation of the proposed FRGP.
The initial study and MND also serve to address potential environmental impacts
that may occur to the extent an individual restoration activity requires a Streambed
Alteration Agreement (SAA) from the CDFW (See Fish and Game Code, $j 1600 et
seq.). Construction of all or a portion of some of the individual restoration activities
may actually occur in subsequent years, depending on the terms for each respective
individual grant provided by the CDFW.
PROJECT
GOAL AND OBJECTIVES
The primary goal of this restoration program is to maintain and restore natural
watershed processes that create habitat characteristics favorable to salmonids.
The objectives of the restoration program action items are to enhance the
~ -
capability of streams to produce wild anadromous salmonids by maintaining,
restoring, and improving stream habitat essential to salmonid production.
Finally, it is the CDFW's objective to implement this project while not causing
a significant adverse effect on the environment, or reducing the number or restricting
the range of an endangered, threatened or rare species.
BACKGROUND
The CDFW may grant funds for habitat restoration to public and nonprofit
organizations, and Native American tribes. Sections 1501 and 1501.5 of the Fish
and Game Code and Public Resource Code 6217.1 pertain to activities funded by
the CDFW.
The FRGP was established in 1981 and is administered by the CDFW. This
program was initiated by the precipitous drop in the population of fish in coastal
streams, mainly salmon and steelhead. This program was developed as a
mechanism to administer grant funds designated for the restoration of fish
populations. Through the past several decades to the present time, funds allocated
by the California Legislature have been used in this grant program in an effort to
rebuild fish populations (see Fish and Game Code Section 6900 et seq.). Initially,
grants were awarded in three categories: stream restoration, fish rearing, and
education. Since 1997, a more holistic restoration approach has been emphasized
that facilitates habitat enhancement throughout the watershed.
There are many factors responsible for the decline of California coastal
salmon and steelhead stocks. One important factor is the degradation of stream
habitats. Activities in watersheds including logging, mining, road building, livestock
grazing, water diversions, and dam construction have seriously impacted the ability
of fish to survive and reproduce. For example, excessive fine-sediment has reduced
egg and fry survival, removal of riparian vegetation has contributed to increased
water temperatures, habitats have been impaired by water diversions, and culverts
and dams have blocked fish passage. Habitat destruction has been instrumental in
drastically reducing native anadromous fish populations. Natural events such as
wildfire, drought, and floods have exacerbated these problems and accelerated the
alteration of habitat further. The resulting decline in fish populations has caused
extreme financial hardship to a once thriving commercial fishery and drastically
reduced, or in some cases eliminated, a very popular sport fishery. Poor ocean
5
conditions resulting in the collapse of the marine food chain along with the various
factors stated above has culminated in the population crash of the Central Valley
Chinook salmon in 2008 and 2009. This event prompted the closure of recreational
and commercial ocean salmon season in 2008 and 2009. Most stocks have been
reduced to the point where listing under the Federal and State Endangered Species
Acts has become necessary.
The FRGP was instituted as the critical need to restore salmon and steelhead
ha bitat was recognized. Guided by the California Salmonid Stream Habitat
Restoration ~anual4'~ ~dition (Flosi et al., 2009), hundreds of habitat restoration
actions funded by the FRGP have been completed by government agencies, Indian
Tribes and nonprofit groups. Activities have included revegetation with livestock
exclusion fencing, riparian planting, removal of barriers to fish passage, bank
stabilization and other bank protection structures, decommissioning of roads, and
improving drainage systems on existing roads. lnstream structures such as boulder
clusters, wing deflectors, and log cover have also been used. Road crossings that
have impeded fish migration have been replaced with bridges or culverts with natural
stream bottoms allowing fish to access additional stream reaches. Finally, other
watershed improvement activities include installation of fish screens to prevent
entrainment of juvenile salmon and steelhead. These actions create spawning and
nursery habitat. provide escape cover and prevent fine sediments from entering
streams. Project monitoring has shown significant habitat improvements in streams
where this work has taken place. A gradual rebuilding of salmon and steelhead
populations is expected as this program continues.
PROJECT LOCATION
Activities performed in the FRGP typically occur in watersheds that have been
subjected to significant levels of logging, road building, mining, grazing, and other
activities that have reduced the quality and quantity of stream habitat available for
native anadromous fish.
Coastal watersheds previously dominated by mature redwood and Douglas fir
forests, contain extensive road and skid trail systems from tractor logging. These ~- ~
previous mature, forested areas can now be found in various seral stages of
vegetative recovery and are predominate in the coastal FRGP region. Action items
are implemented within the stream course to improve fish habitat. Upslope
restoration actions improve fish habitat by reducing the input of fine sediment to the
stream environment.
Inland locations are usually in watersheds dominated by pine and fir forests,
often with steep unstable terrain; some inland locations are in valley areas in
agricultural use. Most restoration activities are intended to reduce sediment delivery
to streams, and provide spawning and rearing habitat in the streams. Streams
6
flowing through valley areas will be treated to stabilize stream banks and increase
riparian vegetation.
SCHEDULE
The activities carried out in the FRGP typically occur during the annual period
of dry weather. Stream work is normally confined to the period of June 15 through
November 1 or the first significant fall rainfall, which ever comes first. This is to take
advantage of low stream flows and is outside the spawning and egglalevin incubation
period of salmon and steelhead.
Generally, upslope work occurs during the same approximate period. Road
decommissioning and other sediment reduction activities are dependent on soil
moisture content. Equipment access on dirt roads and the ability of equipment to
move soil is inhibited by wet conditions. The scheduling of upslope work may also
be affected by the avoidance of nesting or breeding seasons of birds and terrestrial
animals.
Some activities may continue after November 1, but only where no impact, or
less than significant impacts, will result. This will primarily involve hand-planting of
tree seedlings which typically does not begin until December 1 and may continue
until the end of March. Planting during the wet season is necessary to ensure the
best survival of seedlings.
PROJECT DESCRIPTION
The CDFW releases an annual Proposal Solicitation Notice (Solicitation) for
proposals for fishery restoration and watershed assessment and planning work
throughout California. Following initial review by the CDFW Technical Review Team
(TRT), proposals are sent to appropriate fishery staff for field review, comment, and
scoring, using standardized evaluation criteria. The evaluation process requires
consideration of benefits to the fishery resources, the benefit for targeted species,
project costs, and positive or negative impacts to the environment. The need for work
in particular drainages or sites is evaluated and reviewed by the TRT utilizing the
watershed assessment and planning work funded through the program, and from
other CDFW and agency programs at work in California. The proposals, technical
scores, and comments are forwarded to the California Coastal Salmonid Restoration
Grants Peer Review Committee (PRC). The PRC also evaluates and scores each
proposal, and makes recommendations for funding priorities. After CEQA review is
completed the Director of the CDFW reviews the recommendations of the TRT and
PRC, and makes the final funding decision. Grants are written for the approved
action items.
The FRGP operates under two Regional General Permits (RGP) issued by the
U.S. Army Corps of Engineers (USACE). RGP12 (file number: 2003-27922N) was
issued in 201 0 by the USACE San Francisco District and covers action items
implemented within the regulatory boundaries of the San Francisco District. RGP78
(file number: SPL-2003-01123-BAH) was issued in 2009 by the USACE Los Angeles
District and covers action items implemented within the regulatory boundaries of the
Los Angeles District. The RGP's allow the CDFW, grantees, and other individuals
and groups to conduct fishery habitat restoration activities using methods described
in the California Salmonid Stream Habitat Restoration Manual 4'h edition (Flosi et al
2009) that have been evaluated by CDFW biologists. The National Oceanic and
Atmospheric Administration (NOAA) and the U.S. Fish and Wildlife Service (USFWS)
have issued biological opinions, which are incorporated into the corresponding
RGP's. The biological opinions address the impacts of the CDFW's FRGP and
stipulate the mitigations that shall be implemented to avoid and/or minimize impacts
to listed species.
The FRGP shall submit an annual application for a programmatic Section 401
Certificate to the State Water Resources Control Board. A description of project
work and methods to prevent impacts on water quality shall be provided annually to
the State Water Resources Control Board and to the appropriate regional boards.
The CDFW's lake and streambed alteration agreement process (Fish and
Game Code Section 1600 et seq.) is an integral part of stream restoration planning
and implementation. An agreement is developed for each action item which defines
required measures to minimize disturbance to the stream environment. Procedures
to accomplish this task are contained in the CDFW Lake and Streambed Alteration
Program (1600) webpage http:/lwww.df~.ca.qovlhabcon/l600/. Activities such as
installing replacement culverts to provide fish passage, operating equipment in or
near streams, and installing bank stabilizing structures are all discussed in the
context of minimizing impacts, and all required measures for species protection
discussed in this document are incorporated into the agreement for each project.
All features of this project requiring CEQA review are being provided in
sufficient detail to facilitate public review and clearly define the environmental
evaluation. In order to achieve this goal, the FRGP action items are considered to
fall into two categories corresponding to similar activities and requirements for CEQA
review. These two categories of action items are as follows.
Public Involvement, Plannina, Research, Monitorinq. and Habitat Acauisition -
Exempt Action Items
Exempt action items (exempt items) in this category include watershed
evaluation, assessment, planning, habitat acquisition, and monitoring projects. The
names of 45 exempt items in this category are presented in a list in Appendix A,
Exempt Items. These exempt items all qualify as either statutory or categorical
exemptions under CEQA Guidelines sections 15262 (Feasibility and Planning
Studies), 15306 (Information Collection), and 15313 (Acquisition of Lands for Wildlife
Conservation Purposes). These exempt items will not have a significant effect on
physical conditions including land, air, water, minerals, plants, animals, ambient
noise, historic sites, or aesthetics. Based on these facts, these types of exempt
action items will not be discussed further in this document.
Restoration Element - Maior Action Items
There is a notable difference in the level of activity found under this category.
The names of the 45 major action items (action items) in this category are presented
in a list in Appendix A, Action Items. The location of each action item is illustrated on
a state-wide and on CDFW regional level maps in Appendix A. A detailed
description of each action item in this element is also located in Appendix A, sorted
by county.
Stream bank stabilization may include the use of boulder and cobble armoring
of eroding banks, log cribbing, willow mattresses, or willow siltation baffles.
Revegetation of riparian habitat normally involves the use of willow sprigs or willow or
alder seedlings or transplants to stabilize banks and slopes, promote long-term
shade and channel stability, and enhance large-wood recruitment. Indigenous
stocks (when available) shall be used for all planting projects. Upslope earthmoving
and culvert replacement require large size material and increased volumes to be
moved by heavy equipment and, in so doing, involve certain limited construction
activities. The techniques that are used for these action items have proven
successful on many coastal streams and are detailed in the current version of the
California Salmonid Stream Habitat Restoration Manual 4'h edition. This manual
describes in detail how the work shall be performed in the field.
Typically, these stream habitat restoration activities use dump trucks to deliver
logs, root wads, or quarry rock to staging areas, and front-end loaders to deliver
material to restoration sites. Existing stream crossings are used to access the
stream in most cases. If stream crossings do not exist, the least damaging access
points are selected based upon the size, type, and density of riparian vegetation.
Where use of such access points is necessary, riparian vegetation can be affected,
particularly the upper part of plants may be damaged, with the roots and lower parts
receiving minimal damage. Plants damaged in this way usually re-sprout and
recover. Access to restoration activity sites are identified before implementation of
the action item and shall not create bank erosion or cause the removal of riparian
trees. Staging areas at the activity sites are set up on dry stream banks where there
is a minimum, and less than significant, impact to vegetation. Disturbed or bare
mineral soils resulting from work activities, which are subject to surface erosion, are
seeded and straw mulched.
Hydraulic excavators or backhoes may be used to excavate trenches or
keyways in stream banks to anchor logs or boulder structures. Excavators are used
to place materials, construct instream structures, and stabilize stream banks with
boulders and logs. Willow cuttings are usually placed into the keyway trenches
around the logs or boulders and then the trench is backfilled with cobble and native
soil. This procedure anchors the structure into the stream bank, accelerates the
establishment of willows around the structure, and prevents the stream from scouring
around the newly placed structure.
Action items that stabilize stream banks or small stream-side landslides shall
armor and buttress the landslide or stream bank using boulders, logs, root wads, and
loose rock revetment. Revetments are designed with logs, root wads, and boulders
that extend into the stream to provide instream cover and velocity breaks for
salmonids. Smooth riprap, however, which accelerates water velocities along the
stream bank, is not permitted under this program. When practical, the bank will be
sloped back to a minimum 1.5 to 1 slope. A toe trench will be excavated at the toe of
the landslide or eroding bank. The excavated trench shall be backfilled with boulders
and will extend up to the high-water mark. Rock from the toe trench, up to the high-
water mark, shall be of a size that will withstand normal high flows. Revetments shall
extend upstream and downstream of the unstable reach and shall be keyed into the
stable banks.
Runoff from above the slide or eroding banks shall be diverted away from the
area being stabilized. The slide face shall be re-vegetated using indigenous plants.
Willow cuttings shall be placed in the toe trenches. Browse protectors shall be used
on seedlings to prevent predation by browsing animals.
All work, except for the revegetation, shall take place during the summer and
fall (low flow period) and shall be completed by November 1 or before the first
significant seasonal rainfall, which ever comes first. Planting of seedlings takes
place after December 1, or when sufficient rainfall has occurred, to ensure the best
chance of survival of the seedlings, but in no case later than April 15. All habitat
improvements shall be done in accordance with techniques described in the
California Salmonid Stream Habitat Restoration Manual 4Ih edition.
Upslope action items upgrade or decommission roads by implementing all or
part of the following tasks: road ripping or decompacting; installing or maintaining
rolling dips (critical dips); installing or maintaining waterbars and crossroad drains;
replacing, maintaining or cleaning culverts; outsloping roadbeds; re-vegetating work
sites; and excavating stream crossings with spoils stored on site or end-hauled.
Sites which are expected to erode and deliver sediment to the stream are the
only locations where work shall be authorized under this category. Work shall not be
authorized to improve aesthetic values only.
Removal of road and skid trails shall include retrieving unstable material
sidecast during original road construction and excavation of stream crossings and
other watercourse fill. Stream crossings shall be excavated to original width, depth,
and slope to expose natural channel morphology and armor. Side slopes will
generally match original contours above and below the road. Culverts that are
replaced in fish bearing reaches of streams shall be done in a manner to allow for
unimpeded upstream and downstream fish passage.
When fill material is placed on road benches for permanent storage, the road
bench shall be ripped or decompacted first. The fill shall then be placed against the
cutbank and shaped to blend with the surrounding topography that existed prior to
road construction. Outsloping of the roadbed will occur as needed, to reduce
potential sediment delivery to the stream where there is insufficient fill available to
recontour the site, or where there is evidence that the overall long-term stability of
the site does not justify a full recontour treatment. Where practical, fill shall be
compacted to the top of the filled cut to reduce the potential for fill cut failure. Spoil
material shall be stored in stable locations where it will not erode. If stable spoils
storage sites are not available within the project area, they will be end-hauled to a
stable storage site outside of the project area. Areas chosen for this purpose shall
be devoid of tree and shrub vegetation. Upon completion of each site, woody debris
shall be scattered over the surface of the restored area as mulch.
Road crossing removal may involve some removal of vegetation that has
grown in sediment that has been deposited upslope of road prisms. Most of this
vegetation shall be used as coarse wood mulch on bare soils to reduce surface
erosion. Some of the material shall be transplanted on-site as one component of the
restoration action items. In all cases, disruption of existing vegetation shall be
minimized.
Culvert replacement requires diverting stream flow around the project site and
excavating the existing culvert with heavy equipment. Normally concrete footings are
constructed to support a new bottomless culvert or bridge. If appropriate, grade
control structures are incorporated into the project area to prevent excessive down-
cutting of the stream. All work concerning culvert replacement shall be consistent
with current CDFW and NOAA criteria concerning fish passage. Current NOAA fish
passage guidelines can be found on the web at: - -
http:llwww.westcoast.fisheries.noaa.aov/fish ~assa~elsolutions/index.html. CDFW
fish passage guidelines can be found in Part IX of the California Salmonid Stream - -
~abitat Restoration ~anual 4'h edition, available at
http:l/www.dfq.ca.qov/fishlResourcesiHabitatManual.asp.
11
Fish screens are constructed within existing irrigation diversions to prevent
entrainment of juvenile salmon and steelhead. Fish screens are often composed of
a concrete foundation and walls. A steel framework supports perforated screen
panels with a mechanical cleaning system. A stream flow bypass carries the fish
back to the stream. Current NOAA and CDFW fish screen criteria can be found in
Appendix S of the California Salmonid Stream Habitat Restoration Man~al4'~ edition.
Cooperative fish production located at the Kingfisher Flat Hatchery will be
performed using protocols developed by CDFW and NOAA. Furthermore, the
hatchery will follow the criteria found in Appendix B of the California Salmonid
Stream Habitat Restoration Manual 41h edition and the mitigation measures listed in
Appendix B of this document.
Appendix A contains a list of major action item titles, locations, and
descriptions of work that shall be implemented at each site. The action item designs
are reviewed by the CDFW and are implemented by grantees utilizing heavy
equipment and some hand labor crews. During a pre-project inspection, the grantee
and the CDFW will tour the entire activity area and identify the sites and techniques
necessary to carry out the recommendations. The site-specific recommendations
shall be listed in an inspection report which will be acknowledged by the grantee's
signature, as a required element of the activity. The CDFW shall continue to inspect
the work site during and after completion of the action item. All road upgrading or
decommissioning shall be done in accordance with techniques described in Part X of
the California Salmonid Stream Habitat Restoration Manual 4" edition, available at
http:l/w.dfq.ca.~ov/fishiResourceslHabitatManual.as~ All culvert replacement
projects shall be done in accordance with techniques and criteria consistent with
current CDFW and NOAA guidelines concerning fish passage. Implementation of
each major action item shall be conditioned and controlled to prevent any potentially
significant impacts under CEQA.

Environmental Assessment of Each Maior Action Item
Each action item is assigned to the appropriate category using the established
criteria for each category. The work to be completed for each action item is carefully
evaluated to make this determination. Once this evaluation process is completed,
the action items described under the Restoration Element - Major Action Items
section, are subjected to a systematic environmental analysis. This analysis
ultimately prescribes site-specific conditions which must be applied in order to avoid
potentially significant negative effects on the environment, including such effects on
endangered, rare, or threatened species and their habitat.
First, all major action items listed in Appendix A shall comply with CDFW
policies to protect rare, endangered, and listed animal species. A review of the
CDFW's CNDDB for the entire twelve-county project location indicated which animal
species found on a State or Federal special status list may be present at the work
sites. This site specific information is also attached to each statement of work in
Appendix A. Mitigation measures to avoid impacts to these species are presented
along with other mitigation measures in Appendix B, Mitigation Measures, Monitoring
and Reporting Program. In the absence of site-specific information, species
identified as having potential to be affected at a work site shall be assumed present
at the work site and mitigation measures to avoid impact to that species shall be
implemented. Any site-specific surveys to confirm the presence, or absence, of a
listed animal species at a work site will be performed by qualified biologists according
to protocols described in Appendix B. Streambed Alteration Agreements and grants
for each site shall be conditioned to avoid impacts to any special status species that
could potentially be affected at that site. The CDFW shall ensure that the grantee or
responsible party is aware of all specific conditions that apply to their work site. Also,
the CDFW shall inspect the work site before, during, and after completion of the
action item to ensure compliance with mitigation measures to avoid potential impacts
to endangered, rare, or threatened species. Any violation of the specific
recommendations shall be immediately rectified. Failure or inability to rectify a
particular recommendation will cause all work to cease at that site until a remediation
plan is developed.
Second, all major action items listed in Appendix A shall comply with CDFW
policies to conduct rare plant surveys. A qualified botanist shall be contracted to
complete the surveys using standard protocols. Rare plant surveys shall be
conducted following the Protocols for Surveying and Evaluating Impacts to Special
Status Native Plant Populations and Natural Communities (California Department of
Fish and Wildlife, 2009), Appendix C. A review of the CDFW's current California
Natural Diversity Data Base (CNDDB) for each project located in the entire twelve-
county programmatic project area is attached to the statement of work for each major
action item listed in Appendix A and indicates which plant species found on a State
or Federal special status list that could potentially be affected at the work sites. Rare
plant surveys shall be completed prior to any ground disturbing activities. If any
potentially significant impact cannot be avoided, the action item shall not be
implemented. Any site specific recommendations made by a CDFW biologist, or
other qualified biological consultant, to avoid any potentially significant impacts shall
become part of the work plan and incorporated into the measures required in the
issued streambed alteration agreement (Fish and Game Code Section 1600 et seq.).
The CDFW's grant managers shall ensure that the grantee or responsible party is
aware of, and implements, these site specific conditions during routine inspections.
The CDFW shall inspect the work site before, during, and after completion of the
action item. Any violation of the specific recommendations shall be immediately
rectified. Failure, or inability, to rectify a particular recommendation shall cause all
work to cease until a remediation plan is developed that avoids the potentially
significant impact.
Third, all major action items listed in Appendix A shall comply with CDFW
policies to conduct cultural resource surveys, including archaeological or
paleontological surveys (if necessary). A qualified cultural resource specialist(s)
shall be contracted to complete the surveys using standard protocols. Research
shall be done on available cultural data repositories and a review of cultural
resources with regional experts to identify possible areas of importance within the
twelve-county programmatic project area will occur. Site specific detailed research
shall be done for projects sites deemed likely to encounter cultural resources
(Appendix C & D). Review of cultural surveys shall be completed prior to any ground
disturbing activities. If any potentially significant impact cannot be avoided, the
action item shall not be implemented. Any site specific recommendations made by a
qualified cultural specialist, to avoid any potentially significant impacts shall become
part of the work plan and incorporated into the measures required in the issued
streambed alteration agreement (Fish and Game Code Section 1600 et seq.). The
CDFW's grant managers shall ensure that the grantee or responsible party is aware
of, and implements, these site specific conditions during routine inspections. The
CDFW shall inspect the work site before, during, and after completion of the action
item. Any violation of the specific recommendations shall be immediately rectified.
Failure, or inability, to rectify a particular recommendation shall cause all work to
cease until a remediation plan is developed that avoids the potentially significant
impact.
Through careful design, scheduling, and monitoring, any and all potentially
significant impacts associated with the action items shall be avoided or mitigated to
below a level of significance under CEQA. Additional details regarding
implementation of action items, including required mitigation measures, are detailed
in the environmental checklist section below.
Monitoring
Project monitoring is considered an important element in the activity
development and implementation process. The monitoring process provides
performance control during the activity and also helps provide a measure of the
benefits, insight, and guidance for future projects.
Activity during implementation is overseen by a CDFW grant manager and is
geared to ensure that all regulatory environmental issues are strictly addressed
including air, water, and avoiding impacts to sensitive plant and animal species.
During implementation, activities are carefully monitored to make sure plans are
followed and that the correct materials and techniques are used so that the
objectives of the activities are met while protecting the environment.
Post-activity monitoring begins with information collected immediately after the
activity is completed and documents whether the project was completed as designed
and according to grant specifications. This information includes documenting the
exact location where the activity has occurred with reference points and survey
marks. Final project reports should contain "as-built" descriptions with design
drawings and photographs (both before and after the activity) are collected. A
complete activity description including the objectives of the activity must be retained.
The next phase of post-activity monitoring is designed to assess the efficacy
of the project and shall occur within one to three years after an action item is
complete. The CDFW shall randomly select ten percent of the action items within
each project work type for effectiveness/validation monitoring. A random sample,
stratified by project type and region, shall be chosen from the pool of new restoration
projects approved for funding each year. This evaluation shall be recorded on
standard project evaluation forms. Effectiveness monitoring addresses the physical
response associated with an activity, while validation monitoring evaluates fish
response to the project. Pre-treatment monitoring shall be preformed for newly
selected projects, and post-treatment monitoring will be preformed within three years
following project completion.

MITIGATION MEASURES, MONITORING AND REPORTING PROGRAM FOR
THE 2014 FISHERIES RESTORATION GRANT PROGRAM
SECTION 1: MITIGATION
General mitigation measures are implemented for all action items. Specific mitigation measures
are identifiedfor the various species found at or near the project site.' A CDFW grant manager is
assigned to each action item and is responsible for ensuring the general and specific mitigation
measures are implemented.
I. AESTHETICS
No specific mitigation measures are required to protect aesthetics
II. AGRICULTURE RESOURCES
No spec~f~c mltlgatlon measures are requ~red to protect agr~cultural resources
,111. AIR QUALITY -- -....
No specific mitigation measures are required to protect air quality
IV. BIOLOGICAL RESOURCES
A. General Measures for Protection of Biological Resources
1) m. To avoid impacts to aquatic habitat the activities carried out in the restoration
program typically occur during the summer dry season where flows are low or streams are
dry.
a) Work around streams is restricted to the period of June 15 through November 1 or the
first significant rainfall, which ever comes first. Actual project start and end dates,
within this timeframe, are at the discretion of the Department of Fish and Wildlife (i.e.
on the Shasta River proiects must be completed between Julv 1 and September 15 to
avoid impacts to immigrating and emigrating salmonids). ~hii is to take'ad~anta~e of
low stream flow and avoid the spawning and egglalevin incubation period of salmon
and steelhead.
b) Upslope work generally occurs during the same period as stream work. Road
decommissioning and other sediment reduction activities are dependent on soil
moisture content. Non jurisdictional upslope projects do not have seasonal restrictions
in the Incidental Take Statement but work may be further restricted at some sites to
allow soils to dry out adequately. In some areas equipment access and effectiveness
is constrained by wet conditions.
c) The approved work window for individual work sites will be further constrained as
necessary to avoid the nesting or breeding seasons of birds and terrestrial animals. At
most sites with potential for raptor (including northern spotted owls) and migratory bird
nesting, if work is conditioned to start after July 9, potential impacts will be avoided and
no surveys will be required. For work sites that might contain nesting marbled
murrelets, the starting date will be September 16 in the absence of surveys. The work
window at individual work sites could be advanced if surveys determine that nesting
birds will not be impacted.
d) For restoration work that may affect swallow nesting habitat (such as removal or
modification of bridges, culverts or other structures that show evidence of past swallow
nesting activities), construction shall occur after August 31 to avoid the swallow nesting
period. Suitable nestina habitat shall be netted prior to the breedina season to orevent
nesting. Netting shall b'k installed before any nesting activity begins, generally prior to
March 1. Swallows shall be excluded from areas where construction activities cause
nest damage or abandonment,
e) All project activities shall be confined to daylight hours.
2) Projects shall not disturb or dewater more than 500 feet of contiguous stream reach
3) During all activities at project work sites, all trash that may attract predators shall be
properly contained, removed from the work site, and disposed of regularly. Following
construction, all trash and construction debris shall be removed from work areas.
4) Stagingistorage areas for equipment, materials, fuels, lubricants, and solvents, will be
located outside of the stream's high water channel and associated riparian area where it
cannot enter the stream channel. Stationary equipment such as motors, pumps,
generators, compressors, and welders located within the dry portion of the stream channel
or adjacent to the stream, will be positioned over drip-pans. Vehicles will be moved out of
the normal high water area of the stream prior to refueling and lubricating. The grantee
shall ensure that contamination of habitat does not occur during such operations, Prior to
the onset of work, CDFW shall ensure that the grantee has prepared a plan to allow a
prompt and effective response to any accidental spills. All workers shall be informed of the
importance of preventing spills and of the appropriate measures to take should a spill
occur.
5) The number of access routes, number and size of staging areas, and the total area of the
work site activity shall be limited to the minimum necessary to complete the restoration
action while minimizing riparian disturbance without affecting less stable areas, which may
increase the risk of channel instability. Existing roads shall be used to access work sites
as much as practicable.
6) The access and work area limits shall be identified with brightly colored flagging or fencing.
Flagging and fencing shall be maintained in good repair for the duration of project
activities. All areas beyond the identified work area limits shall not be disturbed.
7) Any construction debris shall be prevented from falling into the stream channel. Any
material that does fall into a stream durino construction shall be immediatelv removed in a
manner that has minimal impact to the streambed and water quality.
8) Where feasible, the construction shall occur from the bank, or on a temporary pad
underiain with filter fabric.
9) Any work within the stream channel shall be performed in isoiation from the flowing stream
and erosion protection measures shall be in place before work begins.
a) Prior to dewatering, the best means to bypass flow through the work area to minimize
disturbance to the channel and avoid direct mortality of fish and other aquatic
invertebrates shall be determined.
b) If there is any flow when work will be done, the grantee shall construct coffer dams
upstream and downstream of the excavation site and divert all flow from upstream of
the upstream dam to downstream of the downstream dam.
c) No heavy equipment shall operate in the live stream, except as may be necessary to
construct coffer dams to divert stream flow and isolate the work site.
d) Coffer dams may be constructed with clean river run gravel or sand bags, and may be
sealed with sheet plastic. Upon project completion, sand bags and any sheet plastic
shali be removed from the stream. Clean river run gravel may be left in the stream
channel, provided it does not impede stream flow or fish passage, and conforms to
natural channel morphology without significant disturbance to natural substrate.
e) Dewatering shall be coordinated with a qualified fisheries biologist to perform fish and
amphibian relocation activities.
f) The length of the dewatered stream channel and the duration of the dewatering shall
be kept to a minimum and shall be expected to be less than 300 contiguous feet or 500
total feet per site.
g) When bypassing stream flow around work area, stream flow below the construction
site shall be maintained similar to the unimpeded flow at all times.
h) The work area shall be periodically pumped dry of seepage. Pumps shall be placed in
flat areas, away from the stream channel. Pumps shall be secured by tying off to a
tree or staked in place to prevent movement by vibration. Pump intakes shall be
covered with 0.125 inch mesh to prevent entrainment of fish or amphibians that failed
to be removed. Pump intakes shall be periodically checked for impingement of fish or
amphibians, and shall be relocated according to the approved measured outlined for
each species bellow.
i) If necessary, flow shall be diverted around the work site, either by pump or by gravity
flow, the suction end of the intake pipe shall be fitted with fish screens meeting CDFW
and NOAA criteria to prevent entrainment or impingement of small fish. Any turbid
water pumped from the work site itself to maintain it in a dewatered state shall be
disposed of in an upland location where it will not drain directly into any stream
channel.
j) Fish shall be excluded from the work area by blocking the stream channel above and
below the work area with fine-meshed net or screen. Mesh shall be no greater than 118-
inch diameter. The bottom edge of the net or screen shall be completely secured to the
channel bed to prevent fish from reentering the work area. Exclusion screening shall
be placed in areas of low water velocity to minimize fish impingement. Screens shall
be regularly checked and cleaned of debris to permit free flow of water.
10) Where the disturbance to construct coffer dams to isolate the work site would be greater
than to complete the action (for example, placement of a single boulder cluster), the action
shall be carried out without dewatering and fish relocation. Furthermore, measures shall
be put in place immediately downstream of the work site to capture suspended sediment.
This may include installation of silt catchment fences across the stream, or placement of a
filter berm of clean river gravel, Silt fences and other non-native materials will be removed
from the stream following completion of the activity. Gravel berms may be left in the
stream channel provided it does not impede stream flow or fish passage, and conforms to
natural channel morphology without significant disturbance to natural substrate.
11) Best management practices associated with fish screens and measures to minimize effects
to salmonids associated with fish screen construction, maintenance, and repair are
presented below:
a) Screening projects shall only take place on diversions with a capacity of 60 cfs or
less. Screening larger diversions shall require separate consultation. Fish screens
shall be operated and maintained in compliance with current law, including Fish and
Game Code, and CDFW fish screening criteria. CDFW screening criteria may be
referenced on the Internet at:
hit~://w.dfq.ca.qov/fish/ResourcesiPraects/Enqin/Enain ScreenCriteria.asu.
b) Notwithstanding Fish and Game Code section 6027, fish screens and bypass pipes or
channels shall be in-place and maintained in working order at all times water is being
diverted.
c) If a screen site is dewatered for repairs or maintenance when targeted fish species are
likely to be present, measures shall be taken to minimize harm and mortality to targeted
species resulting from fish relocation and dewatering activities. The responsible party
shall notify CDFW before the project site is de-watered and streamflow diverted. The
notification shall provide a reasonable time for personnel to supervise the
implementation of a water diversion plan and oversee the safe removal and relocation of
salmonids and other fish life from the project area. If the project requires site
dewatering and fish relocation, the responsible party shall implement the dewatering
and relocation measures as described in this document to minimize harm and mortality
to listed species.
d) If a fish screen is removed for cleaning or repair, measures shall be undertaken to
ensure juvenile fish are not passively entrained into the diversion canal. The area shall
be isolated, cleared of fish, and dewatered prior to screen maintenance or replacement.
If dewatering the work area is infeasible, then the area in front of the screen shall be
cleared of fish utilizing a seine net that remains in place until the project is complete. In
the case of a damaged screen, a replacement screen shall be installed immediately or
the diversion shut down until a screen is in place.
e) Fish screens shall be inspected and maintained regularly (not less than two times per
week) to ensure that they are functioning as designed and meeting CDFW fish
screening criteria. During the diversion season, screens shall be visually inspected
while in operation to ensure they are performing properly. Outside the diversion season
when the screening structure is dewatered, the screen and associated diversion
structure shall be more thoroughly evaluated.
f) Existing roads shall be used to access screen sites with vehicles andlor equipment
whenever possible. If it is necessary to create access to a screen site for repairs or
maintenance, access points shall be identified at stable stream bank locations that
minimize riparian disturbance.
g) Sediment and debris removal at a screen site shall take place as often as needed to
ensure that screening criteria are met. Sediment and debris shall be removed and
disposed at a location where it will not re-enter the water course.
h) Stationary equipment used in performing screen maintenance and repairs, such as
motors, pumps, generators, and welders, located within or adjacent to a stream shall
be positioned over drip pans.
i) Equipment which is used to maintain andlor repair fish screens shall be in good
condition and checked and maintained on a daily basis to prevent leaks of materials
that could be deleterious to aquatic life, wildlife, or riparian habitat.
j) To the extent possible repairs to a fish screen or screen site shall be made during a
period of time when the target species of fish are not likely to be present (for example,
in a seasonal creek, repair work should be performed when the stream is dry).
k) Equipment used to maintain and/or repair fish screens shall not operate in a flowing
stream except as may be necessary to construct coffer dams to divert stream flow and
isolate the work site.
I) Turbid water which is generated by screen maintenance or repair activities shall be
discharged to an area where it will not re-enter the stream. If the CDFW determines
that turbidityisiltation levels resulting from screen maintenance or repair activities
constitute a threat to aquatic life, all activities associated with the turbiditylsiltation
shall cease until effective CDFW-approved sediment control devices are installed
andlor abatement procedures are impiemented.
12) Any equipment entering the active stream (for example, in the process of installing a coffer
dam) shall be preceded by an individual on foot to displace wildlife and prevent them from
being crushed
13) If any non-special status wildlife are encountered during the course of construction, said
wildlife shall be allowed to leave the construction area unharmed, and shall be flushed,
hazed, or herded in a safe direction away from the project site. "Special status wildlife" is
defined as any species that meets the definition of "endangered, rare, or threatened
species" in section 15380, article 20 in Title 14 of the California Code of Regulations, also
known as the "CEQA Guidelines".
14) Any red tree vole nests encountered at a work site shall be flagged and avoided during
construction.
15) For any work sites containing western pond turtles, salamander, foothill yellow-legged
frogs, or tailed frogs, the grantee shall provide to the CDFW grant manager for review and
approval, a list of the exclusion measures that will be used at their work site to prevent take
or injury to any individual pond turtles, salamanders, or frogs that could occur on the site.
The grantee shall ensure that the approved exclusion measures are in place prior to
construction. Any turtles or frogs found within the exclusion zone shall be moved to a safe
location upstream or downstream of the work site, prior to construction.
16) All habitat improvements shall be done in accordance with techniques in the California
Salmonid Stream Habitat Restoration Manual. The most current version of the manual is
available at: htt~:ilwww.dfa.ca.ooviiishiResourcesiHabitatManual.as~.
17) The grantee shall have dependable radio or phone communication on-site to be able to
report any accidents or fire that might occur.
18) Installation of bridges, culverts, or other structures shall be done so that water flow is not
impaired and upstream and downstream passage of fish is assured at all times. Bottoms
of temporary culverts shall be placed at or below stream channel grade,
19) Temporary fill shall be removed in its entirety prior to close of work-window
B. Specific Measures for Endangered, Rare, or Threatened Species That Could Occur at
Specific Work Sites
1) Rare Plants
The work sites for the 2014 grants projects are within the range of a variety of rare plant
species. The plant species found on a State or Federal special status list that might be
associated with the 2014 grants projects, was determined from a search of CDFW's
Natural Diversity Database. Because of the large number of widely scattered work sites
proposed, it is not feasible to survey individual work sites in advance and still be able to
implement the restoration projects, due to time limits on the availability of restoration
funds. Lists of special status plant species that might occur at individual work sites are
presented in Appendix A. Past experience with grants projects from previous years has
shown that the potential for adverse impacts on rare plants at salmonid restoration work
sites is very low. Few sites surveyed for rare plants between 1999 and 2012 were found
to have rare plant colonies; disturbance of rare plants was avoided in all cases. In order
to avoid impacts to rare plants during the 2014 grants projects, the following mitigation
measures will be implemented:
a) CDFW or another qualified biological consultant shall survey all work sites for rare
plants prior to any ground disturbing activities. Rare plant surveys will be conducted
following the "Protocols for Surveying and Evaluating Impacts to Special Status Native
Plant Populations and Natural Communities" (CDFW, 2009). These guideiines are
available in Appendix C or on the web at: htt~:iiwww.dfo.ca.oovlhabcon~~lanti.
b) If any special status piant species are identified at a work site, CDFW shall require one
or more of the following protective measures to be implemented before work can
proceed:
a) Fencing to prevent accidental disturbance of rare plants during construction,
b) On-site monitoring by a qualified biologist during construction to assure that rare
plants are not disturbed, and
c) Redesign of proposed work to avoid disturbance of rare plants
c) If it becomes impossible to implement the project at a work site without potentially
significant impacts to rare plants, then activity at that work site shall be discontinued.
d) CDFW shall ensure that the grantee or responsible party is aware of these site-specific
conditions, and shall inspect the work site before, during, and after completion of the
action item.
2) California freshwater shrimp (Svncaris oacifica)
Of the 45 work sites proposed as part of the 2014 grants program, four occur within the
range of California freshwater shrimp (CFS) (724288 Salmon Creek Dairy Water
Conservation Project, 724330 Devils Gulch In-Stream Large Woody Debris Project,
724350 Green Valley Creek Coho Habitat Enhancement Project - Phase 2, and 724361
Green Valley Creek Off Channel Winter Refugia Habitat Enhancement Project) (Appendix
A). The range of the CFS includes Marin, Napa, and Sonoma counties, excluding the
Gualala River watershed. Therefore, the potential for impacts to CFS shall be mitigated
by complying with all of the mandatory terms and conditions associated with incidental
take authorized by the U. S. Fish and Wildlife Service (USFWS), Biological Opinions (file
no. 1-1-03-F-273 and 81420-2009-1-0748-1). CDFW proposes to implement the following
measures to minimize adverse effects to the CFS and its habitat:
a) Project activities in potential shrimp habitat shall be restricted to the period between
July 1 and November 1.
b) At least 15 days prior to the onset of activities, CDFW shall submit the name(s) and
credentials of biologists who will conduct activities specified in the following measures
to the USFWS. The grantee shall implement any additional conservation measures
requested by CDFW andior the USFWS.
c) CDFW shall be notified at least one week in advance of the date on which work will
start in the stream, so that a qualified CDFW biologist can monitor activities at the work
site. All work in the stream shall be stopped immediately if it is determined by CDFW
that the work has the potential to adversely impact shrimp or its habitat. Work shall not
recommence until CDFW is satisfied that there will be no impact on the shrimp.
d) Where appropriate, a USFWS-approved CDFW biologist will survey each site for
shrimp before allowing work to proceed and prior to issuance of a Streambed
Alteration Agreement. All overhanging vegetation, undercut banks, and tree roots will
be surveyed with a butterfly net or fish net.
e) Prior to the onset of work at a work site that may contain shrimp, the USFWS-approved
CDFW biologist shall conduct a training session for all construction personnel. At a
minimum the training shall include a description of the shrimp and its habitat, the
importance of the shrimp and its habitat, the general measures that are being
implemented to conserve the shrimp as they relate to the work site, and the work site
boundaries where construction may occur.
f) Only USFWS-approved biologists shall participate in the capture, handling, and
monitoring of shrimp. CDFW shall report annually on the number of capture, release
and injuriesimortality and agrees to modify captureirelease strategy with USFWS staff
as needed to prevent adverse effects.
g) In site locations where shrimp are present, CDFW will require the grantee to implement
the mitigation measures listed:
a) Equipment work shall be performed only in riffle, shallow run, or dry habitats,
avoiding low velocity pool and run habitats occupied by shrimp, unless shrimp are
relocated according to the protocol described below. "Shallow" run habitat is
defined as a run with a maximum water depth, at any point, less than 12 inches,
and without undercut banks or vegetation overhanging into the water.
b) Hand placement of logs or rocks shall be permitted in pool or run habitat in stream
reaches where shrimp are known to be present, only if the placement will not
adversely affect shrimp or their habitat.
c) Care shall be taken during placement or movement of materials in the stream to
prevent any damage to undercut stream banks and to minimize damage to any
streamside vegetation. Streamside vegetation overhanging into pools or runs shall
not be removed, trimmed, or otherwise modified.
d) No log or rock weirs (including vortex rock weirs), or check dams shall be
constructed that would span the full width of the low flow stream channel.
Vegetation shall be incorporated with any structures involving rocks or logs to
enhance migration potential for shrimp.
e) No dumping of dead trees, yard waste or brush shall occur in shrimp streams,
which may result in oxygen depletion of aquatic systems.
h) If in the opinion of the USFWS-approved biologist, adverse effects to shrimp would be
further minimized by moving shrimp away from the project site, the following procedure
shall be used:
a) A second survey shall be conducted within 24 hours of any construction activity
and shrimp shall be relocated to the nearest suitable habitat. Shrimp shall be
moved while in the net, or placed in buckets containing stream water. Stress and
temperature monitoring of shrimp shall be performed by the USFWS-approved
bioiogist. Numbers of shrimp and any mortalities or injuries shall be identified and
recorded. Shrimp habitat is defined as reaches in low elevation (less than 116 m)
and low gradient (less than one percent) streams where banks are structurally
diverse with undercut banks, exposed fine root systems, overhanging woody
debris or overhanging vegetation.
b) When no other habitat exists on a landowner's property, the shrimp shall be held in
suitable containers with site water and released at the end of the day. Containers
shall be placed in the shade.
i) If moving the shrimp out of the work area cannot be accomplished, and other
avoidance measures have been deemed inappropriate, CDFW shall drop activities at
the work site from the project.
j) A USFWS-approved CDFW biologist shall be present at the work site until such time
as all removal of shrimp, instruction of workers, and habitat disturbance associated
with the restoration project have been completed. The USFWS-approved biologist
shall have the authority to halt any action that might result in the loss of any shrimp or
its habitat. If work is stopped, the USFWS-approved biologist shall immediately notify
CDFW and the USFWS.
k) If a work site is temporarily dewatered by pumping, intakes shall be completely
screened with wire mesh no larger than 0.2 inch to prevent shrimp from entering the
Dump svstem. Water shall be released or pumped downstream at an appropriate rate . . .. .
to maintain downstream flows during construction. Upon completion of construction
activities, any barriers to flow shall be removed in a manner that would allow flow with
the least disturbance to the substrate.
I) A USFWS-approved biologist shall permanently remove from within the project work
site, any individuals of exotic species, such as bullfrogs, centrarchid fishes, and non-
native crayfish, to the maximum extent possible. The grantee shall have the
responsibility that such removals are done in compliance with the California
Department of Fish and Wildlife.
m) lnvasive non-native vegetation that provides shrimp habitat and is removed as a result
of Program activities shall be replaced with native vegetation that provides comparable
habitat for the shrimp. Re-vegetated sites shall be irrigated as necessary until
vegetation is established. Re-vegetated sites shall be monitored until shading and
cover achieves 80% of pre-project shading and cover and for a minimum of 5 years.
3) Coho salmon (Oncorhvnchus kisufch). Chinook salmon (Oncorhvnchus
tshawvtscha), steelhead (Oncorhvnchus mykiss), and coast cutthroat trout
JOncorhvnchus clarki clarkb
While all of the work proposed under this program will enhance habitat for one or more of
these species, all of the work sites proposed as part of the 2014 grants program could
involve instream work in their habitat (Appendix A). In order to avoid any potential for
negative impacts to these species, the following measures will be implemented:
a) Project work within the wetted stream shall be limited to the period between June 15
and November 1, or the first significant rainfall, or which ever comes first. This is to
take advantage of low stream flows and to avoid the spawning and egglalevin
incubation period of salmon and steelhead. Actual project start and end dates, within
this timeframe, are at the discretion of the Department of Fish and Wildlife (i.e. on the
Shasta River projects must be completed between July 1 and September 15 to avoid
impacts to immigrating and emigrating salmonids). Whenever possible, the work
period at individual sites shall be further limited to entirely avoid periods when
salmonids are present (for example, in a seasonal creek, work will be confined to the
period when the stream is dry).
b) Suitable large woody debris removed from fish passage barriers that is not used for
habitat enhancement, shall be left within the riparian zone so as to provide a source for
future recruitment of wood into the stream, reduce surface erosion, contribute to
amounts of organic debris in the soil, encourage fungi, provide immediate cover for
small terrestrial species and to speed recovery of native vegetation.
c) Prior to dewatering a construction site, fish and amphibian species shall be captured
and relocated by CDFW personnel (or designated agents). The following measures
shall be taken to minimize harm and mortality to listed salmonids resulting from fish
relocation and dewatering activities:
a) Fish relocation and dowatering activities shall only occur between June 15 and
November 1 of each year.
b) Fish relocation shall be performed by a qualified fisheries biologist, with all
necessary State and Federal permits. Rescued fish shall be moved to the nearest
appropriate site outside of the work area. A record shall be maintained of all fish
rescued and moved. The record shall include the date of capture and relocation,
the method of capture, the location of the relocation site in relation to the project
site, and the number and species of fish captured and relocated. The record shall
be provided to CDFW within two weeks of the completion of the work season or
project, whichever comes first.
c) Electrofishing shall be conducted by properly trained personnel following NOAA
Guidelines for Electrofishing Wafers Confaining Salmonids Listed under the
Endangered Species Act, June 2000.
-
d) Prior to capturing fish, the most appropriate release location(s) shall be
determined. The following shall be determined:
i) Temperature: Water temperature shall be similar as the capture location.
ii) Habitat: There shall be ample habitat for the captured fish.
iii) Exclusions from work site: There shall be a low likelihood for the fish to
reenter the work site or become impinged on exclusion net or screen.
e) The most efficient method for capturing fish shall be determined by the biologist.
Complex stream habitat generally requires the use of electrofishing equipment,
whereas in outlet pools, fish may be concentrated by pumping-down the pool and
then seining or dipnetting fish.
f) Handling of salmonids shall be minimized. However, when handling is
necessary, always wet hands or nets prior to touching fish.
g) Temporarily hold fish in cool, shaded, aerated water in a container with a lid.
Provide aeration with a battery-powered external bubbler. Protect fish from
jostling and noise and do not remove fish from this container until time of release.
h) Air and water temperatures shall be measured periodically. A thermometer shall
be placed in holding containers and, if necessary, periodically conduct partial water
changes to maintain a stable water temperature. If water temperature reaches or
exceeds 18 "C, fish shall be released and rescue operations ceased.
i) Overcrowding in containers shall be avoided by having at least two containers and
segregating young-of-year (YOY) fish from larger age-classes to avoid predation.
Larger amphibians, such as Pacific giant salamanders, shall be placed in the
container with larger fish, If fish are abundant, the capturing of fish and
amphibians shall cease periodically and shall be released at the predetermined
locations.
j) Species and year-class of fish shall be visually estimated at time of release. The
number of fish captured shall be counted and recorded. Anesthetization or
measuring fish shall be avoided.
k) If feasible, initial fish relocation efforts shall be performed several days prior to the
start of construction. This provides the fisheries biologist an opportunity to return
to the work area and perform additional electrofishing passes immediately prior to
construction. In many instances, additional fish will be captured that eluded the
previous day's efforts.
I) If mortality during relocation exceeds three percent, capturing efforts shall be
stopped and the appropriate agencies shall be contacted immediately.
m) In regions of California with high summer temperatures, relocation activities shall
be performed in the morning when the temperatures are cooler.
n) CDFW shall minimize the amount of wetted stream channel that is dewatered at
each individual project site to the fullest extent possible.
o) Additional measures to minimize injury and mortality of salmonids during fish
relocation and dewatering activities shall be implemented as described in Part IX,
pages 52 and 53 of the California Salmonid Stream Habitat Restoration Manual.
d) Mitigation measures for the cooperative rearing project at the Kingfisher Flat
Conservation Genetic Rearing Facility (Facility) shall follow the conditions set forth by
the CDFW.
a) The hatchery infrastructure at the Facility shall be maintained in an acceptable
condition and good operating order, such that salmonid eggs and fry will be
handled and reared under the controlled conditions necessary for their successfui
incubation without unnecessary or undue mortality.
b) The Facility Manager on staff shall be a qualified fish aquaculturist with credentials,
education and experience representing a level of expertise commensurate with the
responsibilities associated with spawning, rearing and managing a critically
endangered species.
c) Accurate records shall be kept by the Monterey Bay Salmon and Trout Project
(MBSTP) using CDFW Form 788 and annual report forms. No later than ten (10)
days after completion of spawning operations, the completed forms shall be sent to
the CDFW Fish Rearing Coordinator, Manfred Kittel at 7329 Silverado Trail, Napa,
CA 94558. Completed annual report forms shall be submitted to the CDFW Fish
Rearing Coordinator no later than July 1 of the subject spawning year.
d) Unannounced inspections shall be periodically conducted by the CDFW Fisheries
Biologist, or by CDFW law enforcement personnel, whenever fish are being
spawned. Notice of intent to spawn shall be provided by the Facility Manager to
CDFW via telephone or email, as far in advance of any spawning as is practicable.
e) At all times while the fish trap and holding facilities are in operation or fish are
being held, they shall be closely attended by the Facility Manager or his or her
designee. Names of all designated trapping assistants shall be provided to CDFW
at least 48 hours in advance of carrying out any trapping activities. No other
person not possessing the necessary state and federal permits to handle CCC-
steelhead shall be allowed to participate without first obtaining written approval
from the CDFW Biologist or Fish Rearing Coordinator. As the qualified fish
aquaculturist on staff, the Facility Manager shall have sole authority and
responsibility at all times for proper management and handling of the fish.
f) Free passage past the trap will be maintained for fish when the trap is not being
actively operated.
g) Facility operations shall follow the appropriate aquaculture and hatchery practices
for conservation anadromous hatchery facilities. Practices may be evaluated and
revised in consultation with CDFW's Hatchery Operations Committee to ensure
practices to adhere to conservation principles.
h) If there are disease or pathogen concerns at any point in facility operations,
CDFW's Fisheries Pathology Laboratory shall immediately be contacted and
consulted with to investigate, and remediate if necessary, conditions at the facility
to ensure healthy fish stock.
i) All wild and captive coho salmon shall be spawned in strict accordance with the
Spawning Genetic Matrix (SGM) prepared by Dr. Carlos Garza of NOAA Fisheries.
The SGM is based on the genotype of each individual fish and identifies the most
appropriate spawning pairs with the goal of minimizing risks of outbreeding or
inbreeding depression. All female steelhead shall be spawned with up to four (4)
males taken at approximately the same time the female was obtained.
j) Coho salmon: The Facility is authorized to take eggs from up to 30 male, and 10
female wild coho salmon that return to Scott Creek. At the discretion of the NOAA
biology team and CDFW Fish Rearing Coordinator, wild coho salmon returns from
streams other than Scott Creek shall be appropriately captured, taken to the
Facility and included in the SGM. There are currently 156 captive broodstock coho
salmon being held at the NOAA lab, Warm Springs Hatchery and the Monterey
Bay Salmon and Trout Project (MBSTP), which will also be brought back to the
Facility and spawned in the 2013-2014 spawning season. The Facility is
authorized to rear up to 45,000 coho salmon eggs, total. Steelhead: The Facility
is authorized to take eggs from up to 60 male, and up to 20 female wild San
Lorenzo River returns. In addition, the facility is authorized to take eggs from up to
28 male, and 7 female wild Scott Creek returns. No wild steelhead returns from
any other streams may be taken for propagation purposes. The facility is
authorized to rear up to 45,000 steelhead eggs, total.
k) Disposition of 2013-2014 brood year (BY) coho salmon eggs: Coho salmon shall
be released as follows: 4,000 unfed fry in Scott Creek in spring 2014; 6,000 as
unfed fry at predetermined locations on San Vicente Creek in spring 2014; 5,000
as fingerlings in December 2014: 360 of most robust and morphologically superior
to be kept as broodstock; the remainder (expected approx. 41,000) released in
spring of 2015 as smolts.
I) Planned outbreedings of Scott Creek run fish may occur at the discretion of the
NOAA biology team and the CDFW Rearing Coordinator and will include fish
native to CCC coho salmon runs occurring north of the Goiden Gate Bridge,
preferably coho salmon of Russian River andlor Olema Creek origin and
depending upon availability, suitability and Facility capacity. All other spawning
protocols apply.
m) Any San Lorenzo River steelhead eggs to be used for the Salmon and Trout
Education Program (STEP) program shall be taken from the 40,000 egg allotment,
in batches at the discretion of the CDFW and the Facility Manager.
n) No spawning of any fish may occur at the Facility if there is a pending storm event
that stands to cause a failure at the Facility during the first 48 hours of incubation
(when the eggs can't be moved). Under these circumstances, spawning will be
delayed until storm threats pass.
o) The weir and trap apparatus shall be removed from the stream or, if a permanent
installation, modified to provide free passage of fish past the apparatus, once the
limit of fish or eggs has been reached, whichever event occurs first.
p) San Lorenzo River steelhead may be trapped at the Felton Diversion Dam upon
receipt of permission by the property owner, City of Santa Cruz. Scott Creek coho
salmon and steelhead may be trapped at the weir maintained by NOAA Fisheries
on Scott Creek. All other collection of adult saimonids destined for use in the
Facility program shall be limited to manual collection using dip nets and seines.
Adult fish in the act of spawning shall not be taken. All normal and customary
precautions to ensure the safety and health of the fish shall be taken.
q) Weather and habitat conditions permitting, it is appropriate to begin to capture
returning adult steelhead during the first week of December (between December 5
and December 10,2014).
r) Determination of the use of naturally produced coho salmon in the MBSTP captive
spawning program will be made by CDFW & NOAA Fisheries during the season.
Few, if any, wild coho salmon returns are expected. All captured adult wild coho
salmon will be included, if genetically appropriate, in the spawning matrix to
maximize the genetic diversity of Scott Creek fish used in the restoration effort.
s) All fish shall remain the property of the State of California and their ultimate
disposition remains solely at the discretion of CDFW.
t) All 2013-2014 BY juvenile coho salmon reared at the Facility shall be marked with
a coded wire tag (CWT) and a sub-set with a Passive Integrated Transponder
(PIT) tag (no adipose-clipping) prior to release to prevent inadvertent take via
angling and ensure positive identification of any adult returns via PIT-tag readers
installed on Waddell, Scott and San Vicente creeks. All 201 3-2014 BY juvenile
steelhead reared at the Facility shall be appropriately fin-clipped (via removal of
the adipose fin) prior to release.
u) For anesthetization purposes, the use of tricaine methane sulfonate (MS-222) on
coho salmon and steelhead is authorized to prevent handling stress to the fish
which may have adverse impacts on the viability of their gametes. All coho salmon
treated with MS-222 will be either held in captivity for a minimum of twenty one
(21) days post-treatment, or their spawned-out carcasses properly disposed of per
the direction of the Facility Manager and NOAA biology team. All steelhead
treated with MS-222 must be held for a minimum of twenty one (21) days prior to
release back to the stream. Alternatively, fish may be anesthetized with carbon
dioxide in solution, if it is deemed necessary or acceptable by either the Facility
Manager or NOAA biologist. Fish may not be treated with nor exposed to any other
drug or other chemical during any activity carried out without prior written approval
from the CDFW Fish Rearing Coordinator or his or her designee.
v) No fish or eggs acquired or produced at the Facility shall be possessed,
transferred, or otherwise disposed of except as authorized by the CDFW in writing.
w) All eggs, fry, and rearing juvenile fish shall be held in separate rearing tanks
andlor raceways according to the site plan developed by NOAA Fisheries. This
ensures the fish are separated by species, stream of origin, brood year and family
group (coho salmon) to the extent possible.
x) If specificaily directed by CDFW, all heads of dead adipose-marked adult fish shall
be removed, placed in plastic bags, frozen and shipped to the CDFW Fish Rearing
Coordinator: Manfred Kittel at 7329 Silverado Trail, Napa, CA 94558. Each bag
shall contain only one head and have securely affixed to it a hard cardboard tag
clearly marked with the following information: Species of fish, sex, date and
location trapped, name of Facility, and name of Facility Manager.
y) When performing planned authorized releases of juvenile fish into any water body,
the Facility Manager shall supervise andlor approve any and all staff and
volunteers proposed to participate in such releases to ensure proper handling and
care of fish.
z) When releasing adult or juvenile steelhead into the San Lorenzo River, all proper
precautions to prevent contamination with or transmission of invasive New Zealand
mud snails shall be observed. Waders, boots, hip boots or other personal gear
used during the planned releases shall follow the decontamination
outlined on CDFW's website: http:l/www,dfq.ca.-ovlinvasiveslmudsnail/.
aa) Juvenile steelhead released by this cooperative rearing program have been
deemed to pose minimal competition risk to wild fish since release of juvenile
steelhead is timed based on fish size and smolt stage, season, and water
temperature, ensuring that they quickly exit to the ocean rather than remaining to
rear in fresh water. Juvenile coho salmon released by this program are deemed to
pose no risk to wild fish, since this program was established and is maintained to
recovery the native genetic stock south of San Francisco Bay, originate from the
genetic stock in this region, and are managed by the program to maximize the
genetic integrity of wild fish to the greatest level that is scientifically feasible.
bb) All coho salmon smolts will be planted in Scott Creek, Waddell Creek, San Vicente
Creek, and any other appropriate watersheds as determined, in writing, by CDFW
and NOAA Fisheries. Planting shall occur proximal to the first new moon after the
spring equinox,
e) If these mitigation measures cannot be implemented, or the project actions proposed
at a specific work site cannot be modified to prevent or avoid potential impacts to
anadromous salmonids or their habitat, then activity at that work site shall be
discontinued.
4) Tidewater aoby (Eucvcloqobius newberrvi)
The tidewater goby was listed by the state of California for protection in 1987, and
federally listed in 1994. However, the fish's need for specific kind of habitat means that
the populations are isolated from each other, and subject to extirpation due to various
human activities, such as draining of wetlands, sand bar breaches, pollutant accumulation
in lagoons, and so forth.
Of the 45 work sites proposed as part of the 2014 grants program, none of the projects
will affect tidewater goby or tidewater goby habitat.
5) California red-leqaed froq (Rana aurora dravtoniQ
Of the 45 work sites proposed as part of the 2014 grants program, 17 occur within the
range of the California red-legged frog. Activities proposed for 724233 NOAA SWFSC

Removal from Malibu Creek Watershed (Appendix A) will not remove or degrade
California red-legged frog (CRLF) habitat; however, precautions shall be required at these
sites to avoid the potential for take of CRLF while using heavy equipment. The potential
for impacts to CRLF will be mitigated by complying with all of the mandatory terms and
conditions associated with incidental take authorized by the USFWS, Biological Opinion
(file no. 1-1-03-F-273, 81420-2009-1-0748-1, and 81440-2009-F-0387 for projects within
the San Francisco District of the USACE, and file no. 2008-F-0441 for projects within the
Los Angeles District of the USACE). CDFW shall implement the following measures to
minimize adverse effects to the CRLF and its habitat:
a) Project activities in potential red-legged frog habitat shall be restricted to the period
between July 1 and October 15.
b) At least 15 days prior to the onset of project activities, CDFW shall submit the
names(s) and credentials of biologists who would conduct activities specified in the
fo'low ng measures No project acrlvlr es shal begln unt~l CDFW has rece ved wrltren
approval from the USFWS tnat !ne blo og~stjs 's q-allfled ro conduct rne *or&
c) Prior to the onset of any project-related activities, the approved biologist must identify
appropriate areas to receive red-legged frog adults and tadpoles from the project
areas. These areas must be in proximity to the capture site, contain suitable habitat,
not be affected by project activities, and be free of exotic predatory species (i.e.
bullfrogs, crayfish) to the best of the approved biologist's knowledge.
d) A USFWS-approved biologist shall survey the project site at least two weeks before
the onset of activities. If red-legged frogs are found in the project area and these
individuals are likely to be killed or injured by work activities, the USFWS-approved
biologist will allow sufficient time to move them from the site before work activities
resume. Only USFWS-approved biologists will participate in activities with the capture,
handling, and monitoring of red-legged frogs.
e) Prior to the onset of project activities, a USFWS-approved biologist shall conduct a
training session for all construction personnel. At a minimum, the training shall include
a description of the red-legged frog and its habitat, the importance of the red-legged
frog and its habitat, the general measures that are being implemented to conserve the
red-legged frog as they relate to the project, and the boundaries within which the project
may be accomplished. Brochures, books and briefings may be used in the training
session, provided that a qualified person is on hand to answer any questions.
f) A USFWS-approved biologist shall be present at the work site until such time as
removal of red-legged frogs, instruction of workers, and habitat disturbance has been
completed. The USFWS-approved biologist shall have the authority to halt any action
that might result in impacts that exceed the levels anticipated by the USACE and
USFWS during review of the proposed action. If work is stopped, the USACE and the
USFWS shall be notified immediately by the USFWS-approved biologist or on-site
biological monitor.
g) If red-legged frogs are found and these individuals are likely to be killed or injured by
work activities, the USFWS-approved biologists must be allowed sufficient time to move
them from the site before work activities resume. The USFWS-approved biologist must
relocate the red-legged frogs the shortest distance possible to one of the predetermined
areas. The USFWS-approved biologist must maintain detailed records of any
individuals that are moved (e.g., size, coloration, any distinguishing features,
photographs (digital preferred) to assist in determining whether translocated animals
are returning to the point of capture. Only red-legged frogs that are at risk of injury or
death by project activities may be moved.
h) A CDFW monitoring plan shall be developed to determine the level of incidental take of
the red-legged frog associated with the Restoration Program funded activities in the
area. The monitoring plan must include a standardized mechanism to report any
observations of dead or injured red-legged frog to the appropriate USACE and USFWS
offices.
i) If a work site is to be temporarily dewatered by pumping, intakes shall be completely
screened with wire mesh not larger than 0.125 inch to prevent red-legged frogs from
entering the pump system. Water shall be released or pumped downstream at an
appropriate rate to maintain down stream flows during construction activities and
eliminate the possibility of ponded water. Upon completion of construction activities,
any barriers to flow shall be removed in a manner that would allow flow to resume with
the lease disturbance to the substrate.
j) Ponded areas shall be monitored for red-legged frogs that may become entrapped.
Any entrapped red-legged frog shall be relocated to a pre-determined receiving area by
a USFWS-approved biologist.
k) A USFWS-approved biologist will permanently remove from the project area, any
individuals of exotic species, such as bullfrogs (Rana catesbiana), centrarchid fishes,
and non-native crayfish to the maximum extent possible. The biologist will have the
responsibility to ensure that their activities are in compliance with the Fish and Game
Code.
I) The USFWS-approved biologist(s) who handle red-legged frogs shall ensure that their
activities do not transmit diseases. To ensure that diseases are not conveyed between
work sites by the USFWS-approved biologist, the fieldwork code of practice developed
bv the Declinina Am~hibian Po~ulations Task Force
(f;ttv://www.fw~aoviCentura!s~kcies informationlvrotocois auideIinesldocs/DAFTA.vdf)
shall be followed at all times.
m) The CDFW or USACE shall report any observation of the incidental take of red-legged
frogs associated with the implementation of the Restoration Program projects in
accordance with RGP78. The USFWS and the USACE must review the circumstances
surrounding the incident to determine whether any patterns of repeated authorized or
unauthorized activities are occurring that may indicate that additional protective
measures are required. If, after completion of the review, the USACE and the USFWS
agree that additional protective measures are required and can be implemented within
the existing scope of the action, the USACE must require the CDFW to implement the
agreed-upon measures within a reasonable time frame; if the corrective actions cannot
be implemented with the scope of the existing action, the USACE and USFWS will
determine whether re-initiation of consultation is appropriate.
n) Despite term and condition h of this section (above), the USACE must immediately re-
initiate formal consultation with the USFWS, pursuant to 7(a) (2) of the Endangered
Species Act, if red-legged frogs are taken within the action area at or in excess of the
incidental take anticipated in the Incidental Take Statement section of the U.S, Fish and
Wildlife biological opinion (file no. 2008-F-0441), whether by project or by year.
o) If these mitigation measures cannot be implemented or the project activities proposed
at a specific work site cannot be modified to prevent or avoid potential impacts to CRLF
or its habitat, then project activity at that work site shall be discontinued.
6) Arrovo toad 1Bufo rnicroscaphus californicus~
None of the proposed projects in the 2014 grants program are located within the range of
the arroyo toad.
7) San Francisco Garter Snake (Thamno~his sirtalis tetrataenia)
Of the projects proposed in the 2014 grants program, one (724335 Gazos Creek Rural
Road Sediment Reduction Project) (Appendix A) is located within the range of the San
Francisco garter snake. The potential for impacts to the San Francisco garter snake will
be mitigated by consulting with the USFWS prior to the implementation of the projects. If
mitigation measures cannot be implemented or the project actions proposed at a specific
work site cannot be modified to prevent or avoid potential impacts to the San Francisco
garter snake or its habitat, then activity at that work site shall be discontinued.
8) Least Bell's Vireo (Vireo bellii pusillusl
Following the listing of the least Bell's vireo subspecies as Federally Endangered in 1986,
there has been much conservation, restoration, monitoring, and research that has taken
place in its southern California range leading to increased populations in some areas. Of
the 45 projects proposed as part of the 2014 grants program, none are within the range of
the least Bell's vireo.
9) Marbled murrelet lBrachvrarn~us marmoratus)
The marbled murrelet is listed as endangered under CESA and threatened under ESA
Activities to protect and restore habitat will not remove or degrade suitable habitat for
marbled murrelets, however nesting birds could be disturbed by the noise from heavy
equipment required for projects such as culvert removal or placement of large woody
debris.
12 of the 45 work sites proposed as part of the 2014 grants program are in potentially
suitable habitat for the marbled murrelet. Activities proposed for the sites 724234 North

(Appendix A) will not remove, degrade, or downgrade suitable marbled murrelet habitat.
As a result, direct injury or mortality of murrelets is not an issue. The potential exists for
noise from heavy equipment work at these sites to disrupt marbled murrelet nesting. To
avoid this potential impact, the following mitigation measures shall be implemented:
a) Restoration work in areas considered by the Arcata and Ventura USFWS offices shall
not be conducted within 0.25 mile of occupied or un-su~eyed suitable marbled
murrelet habitat between March 24 and September 15. Restoration work in areas
considered by the Sacramento USFWS Office shall not be conducted within 0.25 mile
of any occupied or un-surveyed suitable marbled murrelet habitat between November
1 and September 15.
b) The work window at individual work sites near suitable habitat may be modified, if
protocol surveys determine that habitat quality is low and occupancy is very unlikely
c) If these mitigation measures cannot be implemented or the project actions proposed at
a specific work site cannot be modified to prevent or avoid potential adverse effects to
marbled murrelet or their habitat, then activity at that work site shall be discontinued.
d) For projects contained in streams and watersheds included in a USFWS Habitat
Conservation Plan the mitigation measures contained within those Habitat
Conservation Plans shall be followed.
10) Northern spotted owl (Strix occidentalis caurinal
The northern spotted owl is listed as threatened under ESA. Restoration activities should
not alter habitat for northern spotted owls, however nesting birds could be disturbed by the
noise from heavy equipment during projects such as culvert removal or placement of large
woodv debris. Disturbance can be avoided bv limitina heavv eouioment work within 0.25 - , ..
miles of suitable spotted owl habitat to the period outside the nesting season.
Of the 45 work sites proposed as part of the 2014 grants program, 25 are in potentially
suitable habitat for the northern spotted owl (724234 North Fork Big River Coho Stream

Phase 2) (Appendix A). None of the activities will remove, degrade, or downgrade
northern spotted owl habitat. As a result, direct injury or mortality of owls is not likely. The
potential exists for heavy equipment work at these sites to disturb spotted owl nesting. To
avoid this potential effect, the following mitigation measures will be implemented:
a) Work with heavy equipment at any site within 0.25 miles of suitable habitat for the
northern spotted owl shall not occur from November 1 to July 31 for projects in areas
under the jurisdiction of the Sacramento USFWS Office and from November 1 to July 9
for projects in areas under the jurisdiction of the Arcata USFWS Office.
b) The work window at individual work sites may be advanced prior to July 9 or July 31
(corresponding to the different time constraints of the Sacramento and Arcata USFWS
office), if protocol surveys determine that suitable habitat is unoccupied,
c) If these mitigation measures cannot be implemented or the project actions proposed at
a specific work site cannot be modified to prevent or avoid potential impacts to
northern spotted owls or their habitat, then activity at that work site shall be
discontinued and CDW must reinitiate consultation with USFWS.
d) For projects contained within streams and watersheds included in a USFWS Habitat
Conservation Plan the mitigation measures contained within those Habitat
Conservation Plans shall be followed.
11) Willow flycatcher (Empidonax fraillitL
Of the 45 work sites proposed as part of the 2014 grants program, two are in potentially
suitabie habitat for the willow flycatcher (724324 Little River Coho Habitat Enhancement
Project and 724378 Rowdy Creek lnstream Habitat Enhancement Project: Reach II)
(Appendix A). None of the activities proposed for these sites will significantly degrade
existing willow flycatcher habitat; however, the potential exists for the noise from heavy
equipment work or harvesting of re-vegetation material at these sites to disrupt willow
flycatcher nesting. To avoid this potential impact, the following mitigation measures shall
be implemented:
a) Heavy equipment work shall not begin within one quarter mile of any site with known or
potential habitat for the willow flycatcher until after August 31 and for the southwestern
willow flycatcher until after September 15.
b) Prior to any work in areas where riparian habitat is present, a qualified biologist shall
do a habitat assessment and determine whether the area within 500 feet of the project
site is suitable for nesting by southwestern willow flycatchers. If not, work may
proceed without further surveys. If the biologist determines that the area is suitable, a
qualified biologist must monitor before and during the project to determine the status of
the southwestern willow flycatchers within 500 feet of the project site.
c) The work window at individual work sites may be modified, if protocol surveys
determine that nesting birds do not occur within 0.25 miles of the site during the
breeding season.
d) Harvest of willow branches at any site with potential habitat for the willow flycatcher
shall not occur between May 1 and August 31. Harvest of willow branches at any site
with potential habitat for the southwestern willow flycatcher shall not occur between
May 1 and September 15.
e) No more than 113 of any willow plant shall be harvested annually. Care shall be taken
during harvest not to trample or over harvest the willow sources.
f) If any willow flycatchers are observed nesting within 500 feet of the project activities,
work shall cease temporarily until is determined that either the birds are not nesting or
young have fledged.
g) DFG shall ensure that the grantee or responsible party is aware of this site-specific
condition, and shall inspect the work site before, during, and after completion of the
action item.
h) If these mitigation measures cannot be implemented or the project actions proposed at
a specific work site cannot be modified to prevent or avoid potential impacts to willow
flycatcher or their habitat, then activity at that work site shall be discontinued.
12) Point Arena mountain beaver (Aplodontia rufa niqra)
The Point Arena subspecies is only found within a disjunct, 24-square mile area in
western Mendocino County, California. The U.S. Fish and Wildlife Service considers the
range of the Point Arena mountain beaver (PAMB) to include areas five miles inland from
the Pacific Ocean extending from a point two miles north of Bridgeport Landing south to a
point five miles south of the town of Point Arena. PAMB can be found along Nulls Creek,
Malio Pass Creek, Irish Gulch, Alder Creek, Manchester State Park, Lagoon Lake, Lower
Hathaway Creek, City of Point Arena, Lower and Middle Brush Creek, and Hathaway
Creek.
Of the 45 projects proposed as part of the 2014 grants program, none of the projects are
in the range of PAMB.
C. Riparian and re-veqetation
1) Planting of seediings shall begin after December 1, or when sufficient rainfall has occurred
to ensure the best chance of survival of the seedlings, but in no case after April 1.
2) Any disturbed banks shall be fully restored upon completion of construction. Revegetation
shall be done using native species. Planting techniques can include seed casting,
hydroseeding, or live planting methods using the techniques in Part XI of the California
Salmonid Stream Habitat Restoration Manual.
3) Disturbed and compacted areas shall be re-vegetated with native plant species. The
species shall be comprised of a diverse community structure that mimics the native riparian
corridor, Planting ratio shall be 2:l (two plants to every one removed).
4) Unless otherwise specified, the standard for success is 80 percent survival of plantings or
80 percent ground cover for broadcast planting of seed after a period of 3 years.
5) To ensure that the spread or introduction of invasive exotic plants shall be avoided to the
maximum extent possible, equipment shall be cleaned of all dirt, mud, and plant material
prior to entering a work site. When possible, invasive exotic plants at the work site shall be
removed. Areas disturbed by project activities will be restored and planted with native
plants.
6) Mulching and seeding shall be done on ali exposed soil which may deliver sediment to a
stream. Soils exposed by project operations shall be mulched to prevent sediment runoff
and transport. Mulches shall be applied so that not less than 90% of the disturbed areas
are covered. All mulches, except hydro-mulch, shall be applied in a layer not less than two
(2) inches deep. Where feasible, all mulches shall be kneaded or tracked-in with track
marks parallel to the contour, and tackified as necessary to prevent excessive movement.
All exposed soils and fills, including the downstream face of the road prism adjacent to the
outlet of culverts, shall be reseeded with a mix of native grasses common to the area, free
from seeds of noxious or invasive weed species, and applied at a rate which will ensure
establishment.
7) If erosion control mats are used in re-vegetation, they shall be made of material that
decomposes. Erosion control mats made of nylon plastic, or other non-decomposing
material shall not be used.
8) CDfW shall retain as many trees and brush as feasible, emphasizing shade producing and
bank stabilizing trees and brush to minimize impacts to the riparian corridor.
9) If riparian vegetation is to be removed with chainsaws, the grantee shall use saws
that operate with vegetable-based bar oil when possible.
10) Disturbed and decompacted areas shall be re-vegetated with native species specific to
the project location that comprise a diverse community of woody and herbaceous
species.
V. CULTURAL RESOURCES
Ground-disturbance will be required to implement the project at certain locations that,
despite efforts to identify cultural resources, have the potential to affect these resources.
The procedure for a programmatic evaluation of archeological resources is provided in
Appendix E. Potential for inadvertent impacts will be avoided through implementation of
the following mitigation measures:
1) CDFW shall contract with an archaeologist(s) or other historic preservation professional
that meets The Secretary of the interior's Professional Qualifications Standards (36 CFR
Part 61, and 48 FR 44716) to complete cultural resource surveys at any sites with the
potential to be impacted prior to any ground disturbing activities. This work may be
augmented with the aid of a Native American cultural resources specialist that is culturally
affiliated with the project area. Cultural and paleontological resource surveys shall be
conducted using standard protocols to meet CEQA Guideline requirements.
Paleontological survey protocols are listed in Appendix D.
2) If cultural and/or paleontological resource sites are identified at a project location, CDFW
will require one or more of the following protective measures to be implemented before
work can proceed: a) fencing to prevent accidental disturbance of cultural resources during
construction, b) on-site monitoring by cultural andlor paleontological resource professionals
during construction to assure that cultural resources are not disturbed, c) redesign of
proposed work to avoid disturbance of cultural resources.
3) CDFW shall report any previously unknown historic, archeological, and paleontological
remains discovered at a project location to the USACE as required in the RGP.
4) CDFW shall ensure that the grantee or responsible party is aware of these site-specific
conditions, and shall inspect the work site before, during, and after completion of the action
item.
5) Inadvertent Discovery of Cultural Resources - If cultural resources, such as lithic debitage,
ground stone, historic debris, building foundations, or bone, are discovered during ground-
disturbance activities, work shall be stopped within 20 meters (66 feet) of the discovery,
per the requirements of CEQA (January 1999 Revised Guidelines, Title 14 CCR 15064.5
(f)). Work near the archaeological finds shall not resume until an archaeologist that meets
the Secretary of the Interior's Standards and Guidelines suited to the discovery, has
evaluated the materials and offered recommendations for further action. Cultural materials
not associated with human interments shall be documented and curated in place.
6) Inadvertent Discovery of Human Remains - If human remains are discovered during project
construction, work shall stop at the discovery location, within 20 meters (66 feet), and any
nearby area reasonably suspected to overlie adjacent to human remains (Public
Resources Code, Section 7050.5). The county coroner shall be contacted to determine if
the cause of death must be investigated. If the coroner determines that the remains are of
Native American origin, it is necessary to comply with state laws relating to the disposition
of Native American burials, which fall within the jurisdiction of the Native American heritage
Commission (NAHC) (Public Resources Code, Section 5097). The coroner will contact the
NAHC. The descendants or most likely descendants of the deceased will be contacted,
and work shall not resume until they have made a recommendation to the landowner or the
person responsible for the excavation work for means of treatment and disposition, with
appropriate dignity, of the human remains and any associated grave goods, as provided in
Public Resources Code, Section 5097.98.
7) Procedures for treatment of an inadvertent discovery of human remains:
a) Immediately following discovery of known or potential human remains all ground-
disturbing activities at the point of discovery shall be halted.
b) No material remains shall be removed from the discovery site, a reasonable exclusion
zone shall be cordoned off.
c) The CDFW Grant Manager and property owner shall be notified and the CDFW Grant
Manager shall contact the county coroner.
d) CDFW shall retain the services of a professional archaeologist to immediately examine
the find and assist the process.
e) All ground-disturbing construction activities in the discovery site exclusion area shall be
suspended.
f) The discovery site shall be secured to protect the remains from desecration or
disturbance, with 24-hour surveillance, if prudent.
g) Discovery of Native American remains is a very sensitive issue, and all project
personnel shall hold any information about such a discovery in confidence and divulge
it only on a need-to-know basis, as determined by the CDFW.
h) The coroner has two working days to examine the remains after being notified. If the
remains are Native American, the coroner has 24 hours to notify the NAHC in
Sacramento (telephone 9161653-4082).
i) The NAHC is responsible for identifying and immediately notifying the Most Likely
Descendant (MLD) of the deceased Native American.
j) The MLD may, with the permission of the landowner, or their representative, inspect
the site of the discovered Native American remains and may recommend to the
landowner and CDFW Grant Manager means for treating or disposing, with appropriate
dignity, the human remains and any associated grave goods. The descendants shall
complete their inspection and make recommendations or preferences for treatment
with 48 hours of being granted access to the site (Public Resource Code, Section
5097.98(a)). The recommendation may include the scientific removal and non-
destructive or destructive analysis of human remains and items associated with Native
American burials.
k) Whenever the NAHC is unable to identify a MLD, or the MLD identified fails to make a
recommendation, or the landowner or hislher authorized representative rejects the
recommendation of the MLD and mediation between the parties by the NAHC fails to
provide measures acceptable to the landowner, the landowner or hislher authorized
representatives shall re-inter the human remains and associated grave offerings with
appropriate dignity on the property in a location not subject to further subsurface
disturbance in accordance with Public Resource Code, Section 5097.98(e).
I) Following final treatment measures, the CDFW shall ensure that a report is prepared
that describes the circumstances, nature and location of the discovery, its treatment,
including results of analysis (if permitted), and final disposition, including a confidential
map showing the reburial location. Appended to the report shall be a formal record
about the discovery site prepared to current California standards on DPR 523 form(s).
CDFW shall ensure that report copies are distributed to the appropriate California
Historic Information Center, NAHC, and MLD.
8) Pursuant to RGP78 and in accordance to 36 C.F.R. Section 800.13, in the event of any
discovery during construction of human remains, archeological deposits, or any other type
of historic property, the CDFW shall notify the USACE archeological staff (Steve Dibble at
213-452-3849 or John Killeen at 213-452-3861) within 24 hours. Construction work shall
be suspended immediately and shall not resume until USACE re-authorizes project
construction.
9) If it becomes impossible to implement the project at a work site without disturbing cultural
or paleontological resources, then activity at that work site shall be discontinued.
VI. GEOLOGY AND SOILS
There is no potential for a significant adverse impact to geology and soils; implementation of
the restoration project will contribute to an overall reduction in erosion and sedimentation.
Existing roads will be used to access work sites. Ground disturbance at most work sites will
be minimal, except for road improvements or decommissioning. Road improvements and
decommissioning will involve moving large quantities of soil from road fills and stream
crossings to restore historic land surface profiles and prevent chronic erosion and sediment
delivery to streams. In order to avoid temporary increases in surface erosion, the following
mitigation measures will be implemented:
1) CDFW will implement the following measures to minimize harm to listed salmonids
resulting from culvert replacement activities and other instream construction work:
a) All stream crossing replacement or modification designs, involving fish passage, shall
be reviewed and approved by NOAA (or CDFW) engineers prior to onset of work.
b) If the stream in the project location was not passable to, or was not utilized by all life
stages of, all covered salmonids prior to the existence of the road crossing, the project
shall pass the life stages and covered salmonid species that historically did pass there.
Retrofit culverts shall meet the fish passage criteria for the passage needs of the listed
species and life stages historically passing through the site prior to the existence of the
road crossing.
2) CDFW shall implement the following measures to minimize ham to listed salmonids
resulting from road decommissioning activities:
a) Woody debris will be concentrated on finished slopes of decommissioned roads
adjacent to stream crossings to reduce surface erosion; contribute to amounts of
organic debris in the soil; encourage fungi; provide immediate cover for small terrestrial
species; and to speed recovery of native forest vegetation.
b) Work sites shall be winterized at the end of each day to minimize the eroding of
unfinished excavations when significant rains are forecasted. Winterization
procedures shall be supe~ised by a professional trained in erosion control techniques
and involve taking necessary measures to minimize erosion on unfinished work
surfaces. Winterization includes the following: smoothing unfinished surfaces to allow
water to freely drain across them without concentration or ponding; compacting
unfinished surfaces where concentrated runoff may flow with an excavator bucket or
similar tool, to minimize surface erosion and the formation of rills; and installation of
culverts, silt fences, and other erosion control devices where necessary to convey
concentrated water across unfinished surfaces, and trap exposed sediment before it
leaves the work site.
3) Effective erosion control measures shall be in-place at ail times during construction.
Construction within the 5-year flood plain shall not begin until all temporary erosion controls
(i.e., straw bales or silt fences that are effectively keyed-in) are in place down slope or
down stream of project activities within the riparian area. Erosion control measures shall
be maintained throughout the construction period. if continued erosion is likely to occur
after construction is completed, then appropriate erosion prevention measures shail be
implemented and maintained until erosion has subsided.
4) An adequate supply of erosion control materials (gravel, straw bales, shovels, etc.) shall be
maintained onsite to facilitate a quick response to unanticipated storm events or
emergencies.
5) Use erosion controls that protect and stabilize stockpiles and exposed soils to prevent
movement of materials. Use devices such as plastic sheeting held down with rocks or
sandbags over stockpiles, silt fences, or berms of hay bales, to minimize movement of
exposed or stockpiled soils.
6) When needed, instream grade control structures shall be utilized to control channel scour,
sediment routing, and headwall cutting.
7) Temporary stockpiling of excavated material shall be minimized. However, excavated
material shall be stockpiled in areas where it cannot enter the stream channel. Available
sites at or near the project location shall be determined prior to the start of construction. If
feasible, topsoil shall be conserved for reuse at project location or use in other areas.
8) For projects located within the USACE San Francisco District, an annual limit on the
number of sediment-producing projects per HUC 10 watershed shall be implemented to
ensure that potential sediment impacts will remain spatially isolated, thus minimizing
cumulative turbidity effects. Sediment producing projects include instream habitat
improvement, instream barrier removal, stream bank stabilization, fish passage
improvement, upslope road work, and fish screen construction (unless the screen is
located in a diversion ditch and is disconnected from the waterway). The limit of projects
shall be as follows:
Proiects funded bv the FRGP that are not authorized under the RGP (i.e., they have
Square mile of HUC 10 watershed
undergone separate consultation) or have already been authorized by the RGP in
previous years(s) do not count toward the limits described above.
Maximum number of instream and
upslope projects per year
9) Each year, all instream projects shall be separated both upstream and downstream from
other proposed instream projects by at least 1500 linear feet in fish bearing stream
reaches. in non-fish bearing reaches, the distance separating sediment- producing
projects will be 500 feet.
10) Upon project completion, all exposed soil present in and around the project site shall be
stabilized within 7 days. Soils exposed by project operations shall be mulched to prevent
sediment runoff and transport. Mulches shall be applied so that not less than 90% of the
disturbed areas are covered. All mulches, except hydro-mulch, shall be applied in a layer
not less than two (2) inches deep. Where feasible, all mulches shall be kneaded or
tracked-in with track marks parallel to the contour, and tackified as necessary to prevent
excessive movement. All exposed soils and fills, including the downstream face of the
road prism adjacent to the outlet of culverts, shall be reseeded with a mix of native grasses
common to the area, free from seeds of noxious or invasive weed species, and applied at a
rate which will ensure establishment.
11) Soil compaction shall be minimized by using equipment with a greater reach or that exerts
less pressure per square inch on the ground, resulting in less overall area disturbed and less
compaction of disturbed areas.
12) Disturbed soils shall be decompacted at project completion as heavy equipment exits the
construction area.
13) At the completion of the project, soil compaction that is not an integral element of the
design of a crossing should be de-compacted.
VII. GREENHOUSE GAS EMISSIONS
No specific mitigation measures are required. Re-vegetation practices will help offset the
short term, less than significant, greenhouse gas emissions.
VIII. HAZARDS AND HAZARDOUS MATERIALS
The project will not create a significant hazard to the public or the environment. At work sites
requiring the use of heavy equipment, there is a small risk of an accident upsetting the
machine and releasing fuel, oil, and coolant, or of an accidental spark from equipment igniting
a fire. The potential for these impacts will be reduced to a less than significant level through
implementation of the following mitigation measures:
1) Heavy equipment that will be used in these activities will be in good condition and will be
inspected for leakage of coolant and petroleum products and repaired, if necessary, before
work is started.
2) When operating vehicles in wetted portions of the stream channel, or where wetland
vegetation, riparian vegetation, or aquatic organisms may be destroyed, the responsible
party shall, at a minimum, do the following:
a) check and maintain on a daily basis any vehicles to prevent leaks of materials that, if
introduced to water, could be deleterious to aquatic life, wildlife, or riparian habitat;
b) take precautions to minimize the number of passes through the stream and to avoid
increasing the turbidity of the water to a level that is deleterious to aquatic life; and
c) allow the work area to "rest" to allow the water to clear after each individual pass of the
vehicle that causes a plume of turbidity above background levels, resuming work only
after the stream has reached the original background turbidity levels.
3) All equipment operators shall be trained in the procedures to be taken should an accident
occur. Prior to the onset of work, CDFW shall ensure that the grantee has prepared a Spill
PreventionIResponse plan to help avoid spills and allow a prompt and effective response
should an accidental spill occur. All workers shall be informed of the importance of
preventing spills. Operators shall have spill clean-up supplies on site and be
knowledgeable in their proper deployment.
4) All activities performed in or near a stream will have absorbent materials designed for spill
containment and cleanuo at the activitv site for use in case of an accidental s~ill. In an
event of a spill, work shall cease imme'diately. Clean-up of all spills shall be$n
immediately. The responsible party shall notify the State Office of Emergency Sewices at
1-800-852-7550 and the CDFW immediately after any spill occurs, and shall consult with
the CDFW regarding clean-up procedures.
5) All fueling and maintenance of vehicles and other equipment and staging areas shall occur
at least 65 feet from any riparian habitat or water body and place fuel absorbent mats
under pump while fueling. The USACE and the CDFW wili ensure contamination of habitat
does not occur during such operations. Prior to the onset of work, the CDFW will ensure
that the grantee has prepared a plan to allow a prompt and effective response to any
accidental spills. All workers will be informed of the importance of preventing spills and of
the appropriate measures to take should a spill occur.
6) Location of stagingistorage areas for equipment, materials, fuels, lubricants, and solvents,
will be located outside of the stream's high water channel and associated riparian area.
The number of access routes, number and size of staging areas, and the total area of the
work site activity shall be limited to the minimum necessary to complete the restoration
action. To avoid contamination of habitat during restoration activities, trash will be
contained, removed, and disposed of throughout the project.
7) Petroleum products, fresh cement, and other deleterious materials shall not enter the
stream channel.
8) Stationary equipment such as motors, pumps, generators, compressors, and welders,
located within the dry portion of the stream channel or adjacent to the stream, will be
positioned over drip-pans.
9) No debris, soil, silt, sand, bark, slash, spoils, sawdust, rubbish, cement, concrete or
washings thereof, asphalt, paint, or other coating material; oil or petroleum products; or
other organic or earthen material from any construction or associated activity of whatever
nature shall be allowed to enter into, or placed where it may be washed by rainfall or runoff
into, waters of the state. When operations are completed, any excess materials or debris
shall be removed from the work area and disposed of in a lawful manner.
10) All internal combustion engines shall be fitted with spark arrestors.
11) The grantee shall have an appropriate fire extinguisher(s) and fire fighting tools (shovel
and axe at a minimum) present at all times when there is a risk of fire.
12) Vehicles shall not be parked in tall grass or any other location where heat from the exhaust
system could ignite a fire.
13) The grantee shall follow any additional rules the landowner has for fire prevention
14) The potential for mercury contamination is largely predicted by the presence of historic
hydraulic gold mines and mercury (cinnabar) mines (California's Abandoned Mines: A
Report on the Magnitude and Scope of the Issue in the State, DOC 2000). Therefore, only
a few limited areas within the geographic scope of this grant program have any potential
for gravels contaminated with elemental mercury, they are: Middle Klamath River, Salmon
River, Scott River, and the Lower Middle and Upper Trinity River. (Though studies by the
USGS failed to find significant levels of methyl mercury near these mines.)
a) Given the limited geographical potential for encountering mercury contamination (from
historic mining) within the geographic scope, and the limited number of projects within
these areas that will either disturb the channel bottom or import gravels for instream
restoration; the following avoidance and mitigation measure will be adhered to: any
gravel imported from offsite shall be from a source known to not contain historic
hydraulic gold mine tailings, dredger tailings, or mercury mine waste or tailings.
IX. HYDROLOGY AND WATER QUALITY
1) lnstream work shall be conducted during the period of lowest flow.
2) Before work is allowed to proceed at a site, CDFW shall inspect the site to assure that
turbidity control measures are in place.
3) The waste water from construction area shall be discharged to an upland location where it
will not drain sediment-laden water back to stream channel.
4) For projects within the USACE San Francisco District, if instream work liberates a sediment
wedge, 80% of the wedge shall be removed before the sediment is liberated. The required
amount can be modified if NOAA or CDFW hydrologists or hydraulic engineers agree that
removing a smaller amount will better protect and enhance fish habitat in the area of the
project (e.g., leaving some sediment to replenish areas downstream that lack suitable
substrate volume or quality).
5) To control erosion durina and after oroiect imolementation. CDFW shall imolement best
management practices, 2s identified by the abpropriate ~egional Water ~iality Control
Board.
6) Sediment-laden water caused by construction activity shall be filtered before it leaves the
right-of-way or enters the stream network or an aquatic resource area. Silt fences or other
detention methods shall be installed as close as possible to culvert outlets to reduce the
amount of sediment entering aquatic systems.
7) If CDFW determines that turbiditylsiltation levels resulting from an activity or activities
constitute a threat to aquatic life, all activities associated with the turbiditylsiltation shall
cease until effective CDFW approved sediment control devices are installed andlor
abatement procedures are implemented.
8) Poured concrete shall be excluded from the wetted channel for a period of two weeks after
it is poured. During that time the poured concrete shall be kept moist, and runoff shall not
be allowed to enter flowing stream. Commercial sealants shall be applied to the poured
concrete surface where concrete cannot be excluded from the stream flow for two weeks.
If sealant is used, water shall be excluded from the site until the sealant is dry.
9) If the CDFW determines that turbidityisiltation levels resulting from an activity or activities
constitute a threat to aquatic life, all activities associated with the turbiditylsiltation shall
cease until effective CDFW approved sediment control devices are installed andlor
abatement procedures are implemented.
10) Prior to use, all equipment shall be cleaned to remove external oil, grease, dirt, or mud.
Wash sites shall be located in upland locations so that dirty wash water does not flow into
the stream channel or adjacent wetlands.
11) Water conservation projects that include water storage tanks and a Forbearance
Agreement, for the purpose of storing winter water for summer use, require registration of
water use pursuant to the Water Code s1228.3, and require consultation with CDFW and
compliance with all lawful conditions required by CDFW. Diversions to fill storage facilities
during the winter and spring months shall be made pursuant to a Small Domestic Use
Appropriation (SDU) filed with the State Water Resources Control Board (SWRCB).
CDFW will review the appropriation of water to ensure fish and wildlife resources are
protected. The following conditions shall then be applied:
a) Seasonal Restriction: No pumping is allowed when stream flow drops below 0.7 cubic
feet per second (cfs) except as permitted by CDFW in the event of an emergency.
b) Bypass Flows: Pumping withdrawal rates shall not exceed 5% of stream flow. If CDFW
determines that the streamflow monitoring data indicate that fisheries are not
adequately protected, then the bypass flows are subject to revision by CDFW.
c) Cumulative impacts: Pumping days shall be assigned to participating landowner(s)
when streamflows drop below 1.0 cfs to prevent cumulative impacts from multiple
pumps operating simultaneously.
d) Pump Intake Screens: Pump intake screens shall comply with the "2000 California
Depaitment of Fish and Game Screening Criteria"' for California streams that provide
habitat for juvenile coho salmon, Chinook salmon and steelhead. The landowner shall
be responsible for annual inspection and maintenance of screens. Additionally, the
landowner shall be responsible for cleaning screens as needed to keep them free of
debris and ensure that screen function complies with the criteria specifications.
e) These conditions do not authorize incidental take of any species, removal of riparian
vegetation, or bed, bank, or channel alteration.
f) CDFW shall be granted access to inspect the pump system. Access is limited to the
portion of the landowner's real property where the pump is located and those additional
portions of the real property which must be traversed to gain access to the pump site.
Landowners shall be given reasonable notice and any necessary arrangements will be
made prior to requested access including a mutually-agreed-upon time and date.
Notice may be given by mail or by telephone with the landowner or an authorized
representative of the landowner. The landowner shall agree to cooperate in good faith
to accommodate CDFW access.
" Fish Screening Criteria are from "State of California Resources Agency Department of Fish
and Game Fish Screening Criteria, June 19, 2000." The "approach velocity" shall be
calculated according to Section 2C "Screens which are not Self Cleaning." These screening
criteria are available at http:i/iep.water.ca.gov/cvFirtiDFGCriteria2.htm.
X. LAND USE AND PLANNING
No specific mitigation measures are required for land use and planning
XI. MINERAL RESOURCES
No specific mitigation measures are required for mineral resources.
XII. NOISE
Personnel shall wear hearing protection while operating or working near noisy equipment
(producing noise levels 285 db, including chain saws, excavators, and back hoes). No other
specific mitigation measures are required for noise.
XIII. POPULATION AND HOUSING
No specific mitigation measures are required for population and housing
XIV. PUBLIC SERVICES
No specific mitigation measures are required for public services.
XV. RECREATION
No specific mitigation measures are required for recreation.
XVI. TRANSPORTATIONITRAFFIC
The project will not affect transportationltraffic, because erosion control and culvert
replacement projects will occur in wildlandlrural sites with very little use. There is a potential
that culvert replacement at some work sites could temporarily interfere with emergency
access. This potential impact will be avoided through implementation of the following
mitigation measure at any sites where emergency access might be necessary:
1) During excavation for culvert replacement, the grantee shall provide a route for traffic
around or through the construction site.
XVII. UTILITIES AND SERVICE SYSTEMS
No specific mitigation measures are required for utilities and service systems
SECTION 2: MONITORING AND REPORTING
CDFW shall implement the following measures to ensure that individual restoration projects
authorized annually through the RGP (RGP12 and RGP78) will minimize take of listed
salmonids, monitor and report take of listed salmonids, and to obtain specific information to
account for the effects and benefits of salmonid restoration projects authorized through the
RGP.
1) CDFW shall provide USACE, NOAA, and USFWS notification of projects that are
authorized through the RGP. The notification shall be submitted at least 90 days prior to
project implementation and must contain specific project information including; name of
project, type of project, location of project including hydrologic unit code (HUC), creek,
watershed, city or town, and county.
2) CDFW Grant Manager shall inspect the work site before, during, and after completion of
the action item, to ensure that all necessary mitigation measures to avoid impacts are
properly implemented.

Each reach shall be constructed so that the elevation at the base of the fence
does not deviate from the contour more than 113 of the fence height. The fence
shall be placed such that water cannot runoff around the end of the fence; this
may be accomplished by constructing end-returns that angle up theslope.
10. The silt fence should be limited to handle an area equivalent to 90 square
meters (100 sy) per three meters (ten feet) of fence. Caution should be used
where the site slope is greater than 1:l and water flow rates exceed three liters
(0.8 gallons) per second per three meters (ten feet) of fence.

CALIFORNIA ENVIRONMENTAL QUALITY ACT:
CDFW is the Lead Agency responsible for compliance with the California Environmental
Quality Act (CEQA; Pub, Resources Code, § 21000 et seq,). CDFW approved the
Project and adopted the MND for the Project in January 2014 (State Clearinghouse
Number 2013122050). In making its determinations and findings, the State Water
Board must presume that the MND comports with the requirements of CEQA and is
valid (Pub. Resources Code, § 21 167.3, subd. (b).). As such, the State Water Board
has reviewed and considered the environmental document and all proposed mitigation
measures.
The State Water Board reviewed and evaluated the impacts to water quality identified in
the MND for the Project. Impacts to water quality were determined to be less than
significant because the mitigation measures adopted in Attachment E (Mitigation
Measures, Monitoring and Reporting Program for the 2014 Fisheries Restoration Grant
Program from Appendix B of the MND) will assure that Project activities will be in
compliance with water quality standards. The State Water Board finds that the
Mitigation Measures, Monitoring and Reporting Program in the MND for the Project,
along with the conditions in the Certification, to be adequate to reduce water quality
impacts to less than significant levels.
WATER QUALlM GERTiFICATlrON:
i hereby issue the Certification for the 2014 Fisheries Restoraiion Grant Program (FILE
NO. SB140031N) certifying that as long as all of the conditions listed in this Gertifiication
are met, any discharge from the referenced Project will comply with the applicable
provisions of the Glean Water Act sections 301 (EFnuent Limitations), 302 (Water
Quality Related Effiuent Limitations), 303 (Water Quality Standards and lmplemeniation
Plans), 306 (National Standards of Perlormance), and 307 (Toxic and Pretreatment
Effluent Standards). This discharge is also regulated pursuant to State Water Board
Water Quality Order No. 2003-0017-DWQ which authorizes this Certification to serve as
Waste Discharge Requirements pursuant to the Porter-Cologne Water Quality Control
Act (Wat. Cade, $1 3000 et seq.).
Except insofar as may be modified by any preceding conditions, all Certification actions
are contingent on (a) the discharge being limited and all proposed mitigation being
completed in strict wrnplian~e with the conditions of this Certification and the
attachments to this Certification, and (b) compliance with all appli~able requirements of
Statewide Wter Quality Control Plans and Poiicies, the Regional Water Boards' Water
QualiQ Control Plans and Policies, and the MND for the Project.

EXHIBIT F
Revegetation Plan Arrovo Grande Stream Gauge Barrier Modification Proiect
Protocols will follow standard and accepted techniques by the California Department of Fish and Wildlife
(CDFW) as outlined in the California Salmonid Stream Habitat Restoration Manual. The objective of this
rcvegetation effort is to restore temporarily disturbed areas to pre-construction condition or better. The
constmction footprint is anticipated to encompass 4 sinall areas, Site 1: (32' X 50') is an ul>land section at
the top of bank that will provide heavy equipment access to the site; Site 2 (lj'X35') is an uplandlriparian
mixed section that runs from the top to the base to the toe of the bank that will provide access for human
foot traffic; Site 3: (5' X 50') is a riparian section at the base of the bottom of the rip rap where
exploratory trenching will occur; and Site 4: (150' X 5') is a riparian section along the toe of bank which
may be impacted by human and heavy machinery traffic. Site 1 is sparsely populated with native
Manzanita shrubs (Photo 5). These slvubs were planted during the construction of the adjacent outfall.
Approximately 8 to 12 shrubs are estimated for removal to accommodate heavy equipment. Site 2 is
populated primarily with poison oak, as well as a few willows. Tlle poison oak coverage is continuous
over this entire site. The access route will be routed to avoid willows. Some willows may be trimmed.
Site 3 contains willows that were also planted during the constmction of the adjacent outfall. An
estimated 15 to 30 willow trunks less than 2 inches in diameter at breast height will need to be removed to
accommodate trenching. Site 4 is populated with primarily herbaceous native and uon-native vegetation.
Shrubby overhanging vegetation will be trimmed but no shrubs nor trees are slated for removal at this
time.
The numbers described above for removal are estimates only. Before construction, the CCC project
coordinator and project biologist will re-tally the number and species of woody vegetation and trees that
will be removed. Replanting of trees, if any, and shrubs will follow established ratios determined within
the CDFG 1600 Permit for the project. The approximate revegetation area is 3 125 square feet.
Revegetation efforts will be conducted differently at each site due the difference in elevation and impacts.
Planting methods will be determined based on impacts and will follow both a passive and active approach
where native local plant species shall be used for revegetation (Table 1). The passive planting approach
will be in the form of hydro-mulch/seed mix that will be sprayed over disturbed upslope areas following
construction activities, if applicable. The seed mix will be all native local species approved by CDFW
using natural mulch materials. Active planting calls for placing rooted plants that were initially grown in a
local nursery specializing in native local species. Site 1 revegetation will be coilducted using an active
approach and will include upland plants. Site 2 revegetation, which is anticipated to be recolonized by
adjacent poison oak, will be conducted using a passive planting approach. Site 3 and 4 revegetation will
be a combination of active and passive approaches with riparian plantings and willow stakes. Bare areas
will be seeded.
Site preparation and installation methods: Immediately after construction, a^ny bare erodible banks will
be covered with hydro-mulch and seeded. After the first rains, usually November - December, tree
species will be planted in an irreplar pattern at approximately 10 foot centers. Shrubs will be installed at
approximately 4 foot centers. Plants will be installed into holes dug to the depth and width two times the
size of a one gallon container. Loose soil will be placed iuto the hole to elevate the plant lo the desired
height. Tree wells will be constructed around plants. Followiilg installation, the plant will be watered to
fill the tree well. The area around plants will be mulched lo maintain soil moisture and inhibit weed
growth. Colored coded pin flags will be placed next to plantings to identify plant species during
monitoring.
Plants at site 1 will be watered by existing imgation lines. No watering will occur at site 2. Watering of
plants at site 3 and 4 will be conducted using hand watering that will be carried out by the project
proponent. The volume of water received by each tree, if any, will be approximately 5 gallons per week
during the dry season until the trees are mature enough lo sustain on their own. Due lo the proximity of
site 3 and 4 to the creek edge the required watering after the first year is anticipated to be minimal. Hand
watering will initially begin on a cycle of once every week and be adjusted based on monitoring and
weather conditions. During wet months, watering will be phased out at the discretion of the CCSE Project
Manager. All plants must survive and grow for at least three years without supplemental water for the
restoration phase of the project to be eligible for acceptance by CDFW.
Materials. Exposed areas will be hydro-seeded with 100% biodegradable, High Performance-Flexible
Growth Medium (HP-FGM) that is manufactured in the United States and is composed of 100% recycled
thennally refined (within a pressure vessel) wood fibers, crimped interlocking man-made biodegradable
fibers, mineral activators, naturally derived cross linked biopolymers and water absorbents. The HI-
FGM is phytosanitized, free from plastic netting, requires no curing period upon application. DFW
approved native erosion control mix from S & S seed and locally collected seed will be broadcast by hand
and added to the hydro-mulch for dispersal.
Maintenance of plants: Project maintenance will consist primarily of ongoing hand weed management
and hand inigation. Monthly monitoring for the first year will show areas requiring weed maintenance
work and indicate soil moisture conditions. The irrigation regime will also be monitored for efficiency
and changed if necessary.
Plants at site 1 will be watered by existing irrigation lines. No walering will occur at site 2. Watering of
plants at site 3 and 4 will be by hand. Hand watering will initially begin on a cycle of once evcry week
and be adjusted based on monitoring and weather conditions. During wet months, watering will be phased
out as deemed appropriate by the project manager.
Success criteria: The active planting approach involves planting rooted shrubs and trees along the
disturbed areas and following established CDFW survival criteria. All plantings must have a minimum of
80% survival the first year and 100% survival thereafter andor shall attain 75% survival after 3 years.
Prior to the mitigation site(s) being determined successful, no woody invasive species shall be present and
herbaceous invasive species shall not exceed 5% of the cover. Prior to invasive species removal efforts,
baseline data capturing the degree of infestation will he recorded.
If the survival, cover, and other requirements have not been met, replacement plantings will be needed to
achieve thc necessary requirements. Any replacement tree stock, which cannot be grown from cuttings or
seeds, shall be obtained from the California Conservation Corps Native Plant Propagation Nursery or a
native plant nursery preferably from a local business. Replacement plants shall be monitored with the
same survival and growth requirements for 3 years after planting. Where suitable vegetation cannot
reasonably be expected to become established, non-erodible materials, such as hydro-mulch fiber shall be
used for such stabilization.
Monitoring methods: Monitoring will achieve short and long term goals and will be used to evaluate
project success. These will be supplemented with annual photoyaphic monitoring or over the time frame
specified by CDPW in the project 1600 permit.
Short term nzonitoring: The site will be monitored monthly for the first year consisting of a visual
inspection of plant health. Surface soil moisture level will he checked. These inspections will be used to
modify management practices.
Long term morziloring: Long term success will be monitored annually for 3 years, consisting of plant
counts. Colored flags will be used to mark plant locations and colors will correspond with different
species for identification purposes.
Exotic species control: The site will be visually monitored for exotic species. Monthly hand weeding
will occur and if populations are too large a CCC crew will be used annually in spring for weed control
Adaptive Contingency Measures: This project will be considered successful if 75% of the plants
installed suivive for the first three years. Longer tern success will be defined by a visual estimation of 75
percent coverage of native species. If performance standards are not met, remediation activities will be
taken. If mortality exceeds 25%, the areas exhibiting mortality will be replanted with sufficient stock and
monitoring will continue. If mortality of any one species reaches 40%, the replanting will be with another
species showing higher success rates.

Arroyo Grande Creek Stream Gauge Modification Proiect (HB 491
Introduction:
Central Coast Salmon Enhancement (CCSE) will implement the project a
Grande Creek Stream Gaucle Modification Proiect. The project will modify an
existing concrete weir used by the County of San Luis Obispo as part of a gauging
station. The design was funded by FRGP and received review from an
experienced team of biologists, engineers, and other scientists from a range of
public agencies, non-profits, and private firms.
Arroyo Grande Stream Gauge was ranked among the top ten (10) steelhead
barriers in San Luis Obispo County by the Steelhead Recovery Coalition of the
South Central Coast, Fish Passage Task Force, and was identified as the highest
priority passage project in Arroyo Grande Creek. All habitat improvement will follow
techniques in the California Stream Habitat Restoration Manual
The Grantee shall not proceed with on the ground implementation until all
necessary permits, consultations, and/or Notice to Proceed are secured.
The project will modify an existing concrete weir and which will restore reliable
access to 3.3 miles of unimpeded stream habitat for steelhead trout migration. The
barrier modification will provide passage for both adult and juvenile life stages at
both low and high flows by notching the weir to lower the jump height and inverting
the notch to reduce velocity. The new weir, which would be about four feet lower in
elevation than the existing weir, meets fish passage criteria established by NOAA
Fisheries and the California Department of Fish &Wildlife,
Proiect Description:

The Grantee will not proceed with on the ground implementation until all
necessary permits and consultations are secured. Work in flowing
streams is restricted per the Army Corp of Engineers Regional General
Permit. Actual project start and end dates, within this timeframe, are at
the discretion of the California Department of Fish and Wildlife.
The Grantee shall notify the Grantor Project Manager a minimum of five
working days before the project site is de-watered and the stream flow
diverted. The notification will provide a reasonable time for Grantor
personnel to supervise the implementation of the water diversion plan and
oversee the safe removal and relocation of salmonids and other fish life
from the project area. If the project requires dewatering of the site, and
the relocation of salmonids, the Grantee will implement the following
measures to minimize harm and mortality to listed salmonids:
Fish relocation and dewatering activities shall only occur between
June 15 and October 31 of each year.
The Grantee shall minimize the amount of wetted stream channel
dewatered at each individual project site to the fullest extent
possible.
All electrofishing shall be performed by a qualified fisheries biologist
and conducted according to the National Marine Fisheries Service,
Guidelines for Electrofishing Waters Containing Salmonids Listed
under the Endangered Species Act, June 2000.
* The Grantee will provide fish relocation data to the Grantor Project
Manager on a form provided by the Grantor.
Additional measures to minimize injury and mortality of salmonids
during fish relocation and dewatering activities shall be
implemented as described in Part IX, pages 52 and 53 of the
California Salmonid Stream Habitat Restoration Manual.
The stream gauge weir design and installation will meet flow carrying
capacity required for a 100-year flood event as identified by specifications
determined by National Oceanic and Atmospheric Administration (NOAA)
Fisheries and the California Department of Fish and Wildlife (CDFW), for
adult and juvenile salmonid fish passage. The project will follow the
National Marine Fisheries Service (NMFS 2001) Guidelines for Salmonid
Passage at Stream Crossings and criteria for fish passage as described in
Volume II, Part IX, of the California Salmonid Stream Habitat Restoration
Manual. The engineered plans for the stream gauge weir installation shall
be visually reviewed and authorized by NOAA Fisheries or California
Department of Fish and Wildlife engineers prior to commencement of
work.
All habitat improvements will follow techniques described in the California
Salmonid Stream Habitat Restoration Manual, Volume I, and Volume II
Part XI and Part XII. The Granteellandowner will maintain the new
crossing, inspect the crossing in a timely manner and remove debris as
necessary during the storm season.
Final structure design and placement will be determined by field
consultation between the Grantee and the Grantor Project Managers. All
habitat improvements will follow techniques described in the California
Salmonid Stream Habitat Restoration Manual.
