BACKGROUND
The Newhall Ranch Road Bridge Environmental Mitigation project will implement streambed
restoration within the areas of the Santa Clara River (River) and San Francisquito Creek (Creek)
to mitigate the permanent impacts resulting from the Newhall Ranch Road Bridge Widening
project, as authorized through the environmental permits.
In accordance with the provisions of the Natural River Management Plan (NRMP), this project
will remove, maintain, and monitor exotic, highly invasive vegetation, such as Arundo donax
(Giant Reed) and Tamarix spp (Salt Cedar). Mitigation will occur in three areas, described as
(A), (B), and (C) on the attached location map. The NRMP evaluates proposed projects and their
permanent impacts along the River, and is a joint Environmental Impact Report/Environmental
Impact Study that includes authorizations through the U.S. Army Corps of Engineers 404 permit,
California Department of Fish and Wildlife Streambed Alteration Agreement, and the Los
Angeles Regional Water Quality Control Board Waste Discharge Requirements.
The highly invasive, non-native vegetation from the areas within the River has overgrown and
displaced the native vegetation resulting in diminished habitat for wildlife and over consumption
of limited groundwater. By abating and managing the new growth and re -growth of the invasive
vegetation, native plants will re-establish in the area and, in time, native habitats will return.
Another benefit to the abatement of the invasive, non-native plants is the reduction of their
potential contribution to wildfires. These plants, when dry, are highly combustible and, when
growing in a concentrated area, have contributed to the spread of wildfires.
The first year of the Newhall Ranch Road Bridge Environmental Mitigation project will include
the removal of non-native vegetation, and the remaining five years will provide ongoing
maintenance for the streambed restoration to ensure complete abatement and promote the
recruitment of native species that will support indigenous wildlife. This project supports the
Sustaining Public Infrastructure theme of the City of Santa Clarita's (City) five-year strategic
plan, Santa Clarita 2025.
On February 22, 2022, a Request for Proposal (RFP) was prepared and posted on BidNet. On
March 24, 2022, the City received three proposals. Staff reviewed and scored the firms on a 100-
point scale as follows:
Rank Company Location Score
1. HELIX Environmental Planning, Inc. La Mesa, CA 88.33
2. Gothic Landscape, Inc. Santa Clarita, CA 84.00
3. Habitat Restoration Sciences, Inc. Vista, CA 83.33
The scoring system was based on the following criteria: an understanding of the project's
objectives and responsibilities, approach to the required work, consultant's previous experience
with similar projects, experience working within the Santa Clarita Valley, qualifications of the
project team and their resources, and organization of the proposal.

Packet Pg. 161
HELIX Environmental Planning, Inc. (HELIX) demonstrated an in-depth understanding of the
project's needs and provided a detailed scope of work and approach to the project. The
contractor possesses a valid C27 State Contractor's License and is in good standing with the
Contractors State License Board. In addition, HELIX employs personnel who possess active
Category B licenses for landscape maintenance and Category F aquatic licenses. Based on their
experience and qualifications with previous projects and the completeness of their proposal, staff
recommends awarding the maintenance contract to HELIX. The requested contingency will be
used for any unforeseen conditions that may occur during the contract period.
California Government Code 4526 prescribes the selection of professional environmental
services to be based on demonstrated competence and professional qualifications necessary for
the satisfactory performance of the services required and does not authorize the selection of
professional environmental services based on costs. Staff opened HELIX's cost proposal and
negotiated a final contract at a fair and reasonable price for the services requested in the RFP.
ALTERNATIVE ACTION
Other action as determined by the City Council.
FISCAL IMPACT
Upon approval of the recommended actions, adequate funds will be availabe in expenditure
accounts R1006229-516101 and R1006303-516101 to support the recommended contract.

1. Plan of Study/Scope of Work
This section describes our approach to the successful maintenance and monitoring expected under this
contract as presented in the Scope of Work for the Newhall Ranch Road Bridge Environmental
Mitigation project.
Task 1. Year One Activities
Sub -task 1.1. Delineate work area, survey perimeter, place markers, flagging, and create GIS
shapefile.
Prior to abatement activities, the biological monitor and Contractor will delineate and record the
boundary of the work area. The work areas will be defined by the acreage of specific non-native species
to be removed at each of the three areas (Area A, B and C). At Area A, the work area will be up to 4.3
acres of Arundo and tamarisk. At Area B, a total of 1.8 acres of tamarisk that had been previously
treated, and at Area C, an area of 2.6 acres consisting primarily of tobacco tree and other non -natives.
• For Areas A and B, the biological monitor will record the perimeter of the work area using a
handheld Geographic Position Device (GPS) device with sub -meter accuracy (e.g., Trimble
GeoXH; 1.1c).
• Shapefiles (.shp, .shx, .dbf, and .prj) of the Area A and B boundaries and mapped Arundo and
tamarisk to be abated within Area A will be provided to the City (1.1e).
• The biological monitor will establish permanent photo stations throughout the work area that
will be used to monitor vegetation each year for the duration of the project (six years). Six photo
stations will be established for Area A, four photo stations will be established for Area B, and six
photo stations will be established for Area C.
OUTPUT
✓ Shapefiles (.shp, .shx, .dbf, and .prj) of the work area boundary and mapped Arundo and
tamarisk will be provided to the City within seven days of completing the work described in this
sub -task.
Sub -task 1.2 Biological Monitor —Activities and Qualifications
Pre -Work Biological Surveys
Prior to the start of each quarterly maintenance event in Year 1, a biological monitor will survey the
work area for nesting birds, aquatic species, and other sensitive wildlife. The survey results will be valid
for 48 hours after the survey is complete. This sub -task includes six pre -work surveys for the first
quarterly event, one pre -work survey for each the second and third quarterly events, and two pre -work
survey for the fourth quarterly event. The total number of pre -work surveys included in this sub -task is
10(1.2a). This task will be performed by HELIX as well as sub -consultants.
During the pre -work surveys, the biological monitor will slowly and systematically walk the work area to
detect the presence of nesting birds, aquatic species, and other sensitive wildlife. The biological monitor
will record all species observed during the pre -work surveys with a handheld GPS device. If active nests
are observed during the pre -work surveys, the biological monitor will establish an appropriate setback
buffer to avoid direct and indirect impacts and work will be allowed to continue. An appropriate buffer
will be determined based on the species and location of the nest relative to the proposed work. The
biological monitor will coordinate with the City if an appropriate buffer cannot be established to allow
work to continue (1.2b). If the biological monitor observes any threatened or endangered bird species
(e.g., least Bell's vireo [Vireo bellii pusillus], southwestern willow flycatcher [Empidonax traillii extimus],
yellow -billed cuckoo [Coccyzus americanus]) within 300 feet of the proposed work activities, the City will
be contacted immediately. Following coordination with the City, work may proceed if the biological
monitor does not detect any nesting behavior (1.2d). If terrestrial vertebrate species are found, the
biological monitor will record the observation location and ensure that the vertebrates are allowed to
leave the work area unharmed during work. The biological monitor will direct work away from
individuals as necessary to avoid harming the species (1.2c).
This sub -task does not include species -specific focused surveys or moving of sensitive species, which
could require a permitted biologist and/or a biologist with a Scientific Collectors Permit for the species
of interest. Based on the proposed maintenance activities, HELIX assumes wildlife species can be
avoided by directing work away from individuals as necessary so that no physical relocation of species
would be required.
Biological Monitoring
The biological monitor will perform the following tasks during each maintenance event:
• Help ensure no vehicles, equipment, or work may occur in, or passes through, standing or
flowing water (1.2e).
• Verify that no portions or pieces of the removed Arundo and tamarisk remain within the stream
channel (1.2f).
• Inspect in -coming and out -going equipment for Aquatic Invasive Species (AIS) prior to initiating
maintenance activities, particularly the New Zealand mudsnail (Potamopyrgus antipodarum),
zebra mussel (Dreissena polymorpha) and quagga mussel (Dreissena rostriformis bugensis). The
biological monitor will approve or deny access into the work area after inspecting for AIS (1.2g).
• Monitor bird nesting activities within the work area and up to 300 feet of the work area limits
(1.2h).
• Monitor litter and waste management compliance (1.2i).
• Prepare daily monitoring reports (1.2j), which will address all aspects listed in the RFP. One
report will be prepared to summarize the daily monitoring activities and provide a daily
inspection log (Sub -task 1.8a).
• Conduct Worker's Education and Awareness Program (WEAP) training. A brochure will be
provided to project personnel during the WEAP training meeting. The biological monitor will
provide WEAP training to all regular site personnel regarding sensitive biological resources,
resource avoidance, project goals, and best management practices. The biological monitor will
maintain a sign -in sheet to record all attendees. After the initial WEAP training, training will only
be provided to new staff (1.2k).
This sub -task assumes 30 days of biological monitoring during the first maintenance event (the initial
removal effort), one day of biological monitoring during each of the second and third maintenance
events, and four days of biological monitoring during each of the fourth maintenance event for a total of
36 monitoring days and preparation of 36 daily monitoring reports/daily inspection logs. This task
assumes a biologist will be present daily during the entirety of the initial removal effort. The first and
fourth quarterly events are anticipated to occur in the nesting season (generally defined as February 15
through September 15). The second and third quarterly events are anticipated to occur outside of the
nesting season (generally defined as September 16 through February 14). This sub -task also assumes
preparation of one WEAP brochure and conducting one WEAP training prior to each quarterly
maintenance event (four trainings total). If all crew members have previously received training, a new
training will not be provided. HELIX biologists and sub -consultants may perform biological monitoring
activities under this sub -task.
OUTPUT
✓ Coordination with the City via email if nesting birds are detected during the biological
monitoring activities, including a GIS figure of all nest locations and proposed buffers.
✓ Thirty-six daily monitoring reports/daily inspection logs provided to the City weekly as an
electronic PDF.
✓ One WEAP brochure.
Sub -task 1.3 Botanist
The botanist will select target plants (primarily Arundo and tamarisk) for removal and determine
removal methods (i.e., completely remove or cut -and -treat). The botanist will coordinate with the
biological monitor regarding pre -activity surveys, site access, and prevention of harm to habitat and
potential nesting bird activities. Additionally, the botanist will coordinate with the licensed herbicide
applicator regarding adjacent native plants to ensure their protection. The botanist will also assist in
maintaining and approving daily monitoring logs.
OUTPUT
✓ No expected output.
Sub-task-1.4: Licensed Pest Control Applicator
HELIX employs licensed, qualified applicator license (QAL) holders to manage and supervise activities
during the project implementation and maintenance activities involving herbicide application.
Tasks performed by the QAL holder include:
• Coordination with botanist and biologist regarding perennial species management and
treatment schedules, appropriate herbicides, and application techniques.
• Coordination with biologist to ensure equipment and materials follow the requirements of the
Aquatic Invasive Species Control Plan.
• Storage, application, and reporting of herbicide are done in accordance with all regulatory
requirements.
• Implementation of integrated pest management principles, including the reduction of herbicide
application when feasible, precision targeting of individuals, control of drift, wind monitoring,
and scheduling herbicide during appropriate times of year.
• Ordering and verifying all herbicide applied is undiluted, recorded and applied during the correct
weather conditions.
• Quality assurance/control visits to supervise and verify application occurred properly and plant
die -off is visible following application.
OUTPUT
✓ Maintain and record keeping an active qualified applicator license categories B and F throughout
the project duration.
✓ Daily record keeping of herbicide use on the project site.
✓ Monthly summary reports for County regulations requiring herbicide reporting.
✓ Regular quality control/site observation reports verifying that herbicide application is performed
consistent with applicable labels.
Sub-task-1.5: ALL equipment and vehicles shall be decontaminated of Aquatic Invasive Species
HELIX will follow requirements set forth in the Aquatic Invasive Species Control Plan (Plan) as required
by the project RFP documents.
• Worker's Environmental Awareness Plan training for all employees to identify potential aquatic
invasive species on equipment and within the project site.
• Clean and inspect all equipment, hand tools, trucks, trailers, and vehicles that are operating
within the streambed.
o Equipment intended to be operated in the streambed will be cleaned off -site and will
follow the specifications for cleaning listed in the RFP, including adequate flow rate,
nozzle pressure, and water temperature.
OUTPUT'
✓ Representative photographs of the vehicles and equipment cleaning.
✓ Removal of any equipment not cleaned correctly.
✓ Certification that proper cleaning procedures were followed.
Sub-task-1.6: Exotic Vegetation removal, handling, transport, disposal, and herbicide application
HELIX will employ the following tasks during the initial removal of Arundo and tamarisk. The methods
will be selectively applied based on site access, sensitive resources, and surface soil and water
conditions present at the time of work.
• Mobilization, staging area, and access control
o HELIX will develop a staging area in coordination with project biologists and the City.
The staging area will be located outside the streambed, will have temporary
construction fencing delineating its perimeter as well as a portable restroom and
storage container to house chemicals such as herbicide and equipment, and will be
managed daily for dust, track out, and cleanliness. The staging area will also include
secondary containment for equipment to prevent any potential oil leaks from reaching
the soil. Equipment will be staged within the staging area during non -working hours,
including the end of each workday. HELIX will also coordinate access from the staging
area into the streambed where invasive removal is required. All HELIX crew and sub -
consultants will undergo Worker's Environmental Awareness Program (WEAP) training
before work to ensure they are able to identify potential sensitive species and
avoidance areas in the field. As part of the WEAP, crew members will be trained to avoid
surface water with equipment and vehicles.
• Hand cutting and herbicide application
o Hand cutting of invasive species will be performed in areas where equipment cannot
access due to surface water, access issues related to nesting birds, or where native
species are intermixed with invasive species requiring careful removal to avoid impacts
to native species. Hand cutting will be performed using chainsaws and in teams of two
vegetation management crew members. One employee will safely handle standing
vegetation materials, clearing any foreign debris such as rocks or trash at the base of the
plant, allowing for safe and straightforward access to the cutting point for the second
employee. The second employee will be equipped with a chainsaw to make a clean cut
through the vegetation near the base or close to ground level. The first employee will
then handle the cut material and lay it down in a pile out of the way of the remaining
standing vegetation to be cut. The second employee will use a backpack sprayer to
apply an appropriate herbicide, such as Aquamaster or equivalent, mixed with high -
contrast blue dye, to the freshly cut material within a few minutes after cutting. If calm
weather conditions are not present during initial cutting, HELIX will perform a follow-up
cut -stump treatment in following days when winds speeds and associated risk of
chemical drift are low.
• Equipment removal
o Equipment removal will be performed using equipment such as an excavator or
skidsteer. Equipment cutting will be done to prevent mulching, mowing, or masticating
the material into fine pieces so that it can be removed in -tact from the streambed.
Equipment may be used to remove Arundo and tamarisk from within the streambed, or
by staging on adjacent upland areas where equipment can reach into the streambed for
removal. Equipment removal will only occur in stands of vegetation that are
homogenous stands of non-native species, void of any native species.
• Equipment Loading and Hauling
o HELIX will use equipment to load material into a truck and trailer or off -road utility
vehicle with landscape trailers to haul to the staging area. The loading equipment will
use a grapple bucket to pick up previously cut material and place it into the stake -bed
trailer, where it will be secured before hauling. The material will be hauled to the
staging area for processing.
• Hand hauling
o In locations where equipment, including the utility vehicle and trailer, is not accessible,
vegetation management personnel will hand -carry cut material to a suitable location,
whether an equipment access point, a winching access point or a staging area. Teams of
two will carry material by hand and place it in locations to avoid impacts to native
species and other sensitive resources.
• Winching
o HELIX will winch material out of the streambed in certain zones. Winching will be done
in teams of four. Winching will include a truck parked in adjacent upland areas
immediately outside the streambed. Upland adjacent area use is considered acceptable
per the Newhall RFP language. Two crew members in the streambed will tie bundles of
non-native material to the attached rope. One crew member will guide the rope as
winching occurs. One crew member will be operating the winch attached to the truck.
Winched material will then be loaded into a trailer and/or dumpster and taken to the
staging area for processing. A dumpster and/or chipper may be staged within each
winching operation zone. No other materials or equipment would be staged within
winching operation zones.
• Chipping
o Chipping will generally occur inside the staging area. Chipped material will remain on
site and spread as ground cover in adjacent upland areas or staging areas, as approved
by the City.
• Hauling to landfill
o Material that cannot be chipped will be picked up and hauled to Chiquita Landfill for
disposal.
• Site Clean -Up and Demobilization
o Tracks will be cleaned once per week within the streambed where equipment is used.
Tracks will be raked by hand or using a chain link fence panel attached to the back of the
utility vehicle. At the end of the initial removal period, the staging area will be cleared of
all fencing, dumpsters, equipment, and other project -related items.
• Quarterly Maintenance
o After initial removal, three additional maintenance activities will occur during the first
twelve months to treat resprouting invasive species. Herbicide will be applied to Arundo
and tamarisk showing signs of regrowth.
OUTPUT
✓ Mobilization and staging area creation.
✓ Vegetation removal of Arundo and tamarisk.
✓ Chipping of material.
✓ Site -clean up and demobilization.
✓ Retreatment of resprouting invasive species.
Sub -task 1.7 Project Goals
The project will be deemed successful if the following criteria are met by the end of Year Six:
• Arundo and tamarisk treated within the work areas during Year 1 will be completely dead at the
end of Year Six. If there is new growth of these species (either from propagules or seed) in areas
distinct from those initially identified and treated during the first year, these shall not be a
factor in evaluating the success criteria. However, these new populations will be treated as
described in Sub -task 1.6 above and reported separately in the annual report described in Sub -
task 1.8 below.
• There are no additional non-native cover requirements throughout the work area for species
besides Arundo and tamarisk.
OUTPUT
✓ No expected output.
