BACKGROUND
The City of Santa Clarita (City) completed two bridge widening projects on McBean Parkway
and Newhall Ranch Road. These projects removed approximately 200 native trees within the
work zones around the bridges.

In accordance with the California Environmental Quality Act, the National Environmental
Protection Act, and the Natural River Management Plan, the City is required to plant 900 trees
to mitigate the original 200 trees removed during the construction of the McBean Parkway and
Newhall Ranch Road Bridge Widening projects. The City is required to maintain the new trees
for five years until they reach the prescribed tree growth and survivability requirements. This
will include the use of temporary low -flow irrigation for the establishment and then a weaning
off period for long-term sustainability.
Following the completion of the bridge widening projects, and after the severe statewide
drought, the City began the mitigation process by planting 980 replacement trees propagated
from adjacent native tree cuttings in 2020. Additional trees were planted to ensure survivability
requirements were met. The trees were planted near the riverbed and maintained for the first
year of the required five-year growth and survival objectives by a separate contract.
This project will secure the tree growth and survivability requirements for the remaining four
years. The maintenance activities will include monitoring, adjusting, and repairing of the
irrigation system; management of non-native plants and removal of litter from the site;
monitoring the trees for impacts from disease and/or damage (e.g. rodent browsing); and
implement viable treatment(s) or replacement of trees when necessary. The maintenance
activities will also include annual monitoring of growth and survival objectives and create a
report compiled to summarize the site's performance and condition. When completed, the
seven -acre area will provide high value habitat for native wildlife. This project supports the
Santa Clarita 2025 theme of Sustaining Public Infrastructure.
On June 9, 2021, a Request for Proposal (RFP) for the maintenance of the project was prepared
and posted on BidNet. The RFP asked firms to identify their relevant experience with similar
projects and to demonstrate their approach to this project. On June 28, 2021, the City received
two proposals. Based on the evaluation criteria set forth in the RFP, the following is a summary
of the firms' rankings:
Rank Companv Location Score
(Maximum 100 Points)

The HELIX restoration services team has worked on hundreds of projects
throughout Southern California with an emphasis on delivering cost-effective
solutions that benefit the environment. Specific relevant experience on similar
projects related to the Scope of Work provided include projects for Orange County
Waste and Recycling, Stadium Wetland Mitigation, and Southern California Edison
On -Call contracts. Each of these projects required tree planting, irrigation
installation and maintenance, and on -going long-term maintenance to keep tree
survivorship high. At Orange County Waste and Recycling, HELIX has planted and
maintained hundreds of trees at Santiago Canyon mitigation site and at the Olinda
Alpha Landfill. Trees are being hand watered by HELIX crews since automated
irrigation is not possible. At Stadium Wetland, HELIX planted thousands of
willows, cottonwoods, and sycamores and an automated irrigation system across 57 acres of active river channel.
On Southern California Edison projects, HELIX has served as both the installation and maintenance contractor, as
well as biological monitor for tree restoration and habitat restoration sites within Los Angeles County.

HELIX is leading a 57-acre habitat mitigation project within the
San Diego River channel, between Interstate (1-) 15 and 1-805,
south of the former Qualcomm Stadium in the Mission Valley
area of San Diego. The restoration project is serving as mitigation
for multiple public utilities projects for the City of San Diego.
Work is being performed in accordance with regulatory permits
for Regional Water Quality Control Board (RWQCB) 401 Permit
R9-2013-0124; California Department of Fish and Wildlife (CDFW)
Streambed Alteration Agreement 1600-2014-0192-R5; and United
States Army Corps of Engineers (USACE) Nationwide Permit 27 SPL-2014-00416-DB.
The project area includes a one -mile -stretch of river and ranges in width from 300 to 800 feet. Initial phases of
the project included development and implementation of a SWPPP and removal of over 27 acres of non-native
species within the river channel using hand tools and heavy equipment. Removal of non-native vegetation
occurred during winter of 2016-2017, one of the wettest years on record with frequent flooding of the project
site, which HELIX performed under a tight schedule to clear the majority of areas prior to bird nesting season.
Following removal of non-native species, HELIX installed an overhead temporary irrigation system over
approximately 30 acres, followed by native plant and seed installation. Over one thousand trees were installed
in the project area, including willows, sycamores, cottonwoods, and oak trees. The native plant material will aid
in stabilization of the disturbed areas within the river channel and provide native habitat for species such as the
least Bell's vireo. The project is currently in year four of the five-year maintenance period and meeting all
success criteria.

Response File
Under SCE, HELIX is performing restoration and maintenance in areas temporarily disturbed by construction of
the TRTP. HELIX maintains irrigation on approximately 500 scrub oaks (Quercus berberidifolia) species. TRTP
Segment 1 restoration sites are along approximately 13 miles of National Forest Service lands within the ANF.
Kinsey 12kv Underground Replacement Habitat Restoration Maintenance. HELIX is conducting the habitat
maintenance, monitoring, and reporting for the revegetation area associated with the Kinsey 12 kV underground
replacement project in Los Angeles County, near Pyramid Lake. The habitat maintenance activities include weed
abatement, watering, and remedial measures. Restoration monitoring includes maintenance monitoring and
annual monitoring of the revegetation areas. HELIX will also be assisting SCE with negotiating sign -off of the
revegetation area within the ANF.
West of Devers Upgrade Project. HELIX is providing project support on SCE's West of Devers transmission line
project by restoring areas temporarily impacted by construction to pre-existing conditions. Restoration activities
include, but are not limited to, weeding, replanting, reseeding, and providing supplemental irrigation to
established plantings. HELIX is also performing monthly qualitative monitoring and annual quantitative
monitoring on all active restoration areas and preparing an annual report to document site progress.
3. Plan of Study/Scope of Work
Following review of the documents provided as part of the RFP, HELIX understands the growth, survivorship, and
non-native species requirements of this Project. Additionally, HELIX has direct experience of the site, having
installed, and conducted Year 1 of the maintenance period for this project. Because of this experience and other
similar projects, HELIX's approach to maintain and monitor the Project to success are clear and direct, including
managing the existing irrigation system to establish deep rooted trees, promote growth and reduce mortality,
remove non-native species, and monitor the health of trees. This section describes in greater detail our
approach to the successful maintenance and monitoring expected under this contract as presented in the Scope
of Work.
Task 1 Irrigation System. Tree mitigation sites require maintenance of the irrigation system to successfully
achieve the Project's survivorship and height requirements. Because HELIX installed the irrigation system, HELIX
is uniquely positioned to maintain and manage performance of all parts of the irrigation system until trees are
determined to be self-sustaining.
Sub -Task: HELIX biological monitors and field personnel will visit the project monthly during the warmer
months of the year, April through October, and confirm water is being delivered to all tree species. In these
months, HELIX schedules monthly maintenance during which the crew walks drip lines to every plant to
confirm watering and make any required adjustments. HELIX will maintain drip irrigation lines into the
watering dishes (12 total) through the end of Year Three. If watering dishes are broken or missing, HELIX will
replace the watering dishes.
During maintenance events, HELIX staff come prepared with irrigation replacement parts, like valves, piping,
anchors, connections, supports, and controllers to fix any problems that have occurred since the previous
visit. A maintenance event consists of the field personnel monitoring the system under operation and fixing
any identified issues.
HELIX will utilize monitoring report data from the monitoring and annual reports to address specific issues at
each tree or general trends associated with the irrigation system. HELIX will confirm, through
correspondence with the City, that each tree is watered every month. Managers and monitors will
communicate maintenance items to the crews. Each crew has an iPad equipped with software applications
HELIX Response File I Page 4 of 28
Environmental Planning
noes„��„ G..P Tree Mitigation Site Maintenance Years Two through Five I PROPOSAL # ENG-20-21-21
Response File
such as e-mail, Survey123, and Collector, and managers send daily schedules to crew via e-mail. Both
Survey123 and Collector are data management software applications that have been tailored to report field
activities on restoration sites. Crews will send maintenance event reports using Survey123 and Collector so
that managers can review and confirm work has been completed.
The irrigation system will be adjusted accordingly to account for temperature, precipitation, and growth
patterns. HELIX will develop an irrigation plan to ensure trees are getting watered adequately in warm, dry
months and not overwatered in cool, wet months. At the successful completion of Year One, HELIX
anticipates reducing water output in Years Two and Three, allowing trees to grow with supplemental water
and develop naturally independent root systems. HELIX will monitor changes to the trees' reaction to
reduced water, assessing signs of stress, and HELIX will adjust irrigation timers as needed per the monitor's
recommendations. As directed by the biologist if trees are self-sustaining, HELIX will stop irrigating at the
end of Year Three. Through HELIX's understanding of species growth and climate, HELIX will make necessary
adjustments to the irrigation system aiding deep root establishment and healthy tree growth through the
end of Year Three. Irrigation will remain in place until success criteria are met, following which, it will be
removed and properly disposed of.
After the completion of Year Three, HELIX will leave the irrigation system in place until final success criteria
are met. Once final success criteria are met, HELIX will remove and dispose of the irrigation off -site at the
end of Year Five, per the City's approval. The water supply connection will be capped. HELIX will work the
City while the irrigation remains in place in Years Four and Five and turn on the irrigation per the City's
direction for emergency measures to keep trees alive. After Project completion, the Project will be a wildlife
habitat free of man-made irrigation materials.
Output: The output for this task is a constantly functioning irrigation system with a regularly managed
watering schedule during through Years Two and Three of the project, with the expected completion and
removal of the system in Year Five following two years of tree survivorship without irrigation.
Task 2 Tree Care, Maintenance, and Replacement. HELIX will use regular monitoring methods and
adaptive management techniques to meet tree survivorship and height criteria.
Sub -task: HELIX will monitor the mitigation site quarterly (four times per year) during Years Two through
Five. At quarterly monitoring visits, general tree health observations will be recorded, including overall
health of the stand and evidence of rodent and/or insect damage. General site observations will also be
recorded, including human intrusion/impacts, hydrologic conditions (e.g., the presence of surface water),
observations of adjacent native vegetation, and evidence of natural events (e.g., flooding or fire). A list of all
wildlife species observation will also be recorded. The RFP specifies that each tree be individually inspected
during the quarterly visit. However, based on prior experience on the mitigation sites, HELIX believes that a
general observation inspection may be sufficient. The quarterly monitoring visits as proposed in this Scope
of Work will be ample, to detect issues such as disease or herbivory to the trees that may affect the project's
likelihood of meeting the success criteria at the end of Year Five. Additionally, the success criteria are based
on tree height and survivorship. Based on the data collected by HELIX during Year One, the project is already
on track to meet the success criteria. Following each quarterly monitoring visit, HELIX will prepare a report
summarizing the monitoring as described above. The report will also include a map highlighting any areas
within the mitigation site requiring special attention (i.e., protection cages in the event of severe herbivory,
dense patches of non-native plants).
HELIX Response File I Page 5 of 28
Environmental Planning
noes„��„o G..p Tree Mitigation Site Maintenance Years Two through Five I PROPOSAL # ENG-20-21-21
Response File
HELIX maintenance crews will work directly with the biological monitor to implement adaptive management
techniques that promote tree growth and survivorship. During the biological monitoring visits, trees will be
monitored for physical damage, stress from lack of water, disease, non-native plants in the dripline, and
mortality. HELIX maintenance personnel will implement measures that address the biologist's maintenance
list. HELIX's GIS team will create site specific graphics and GIS files to show the biologist's maintenance list
spatially. To promote moisture retention, HELIX will maintain a two -inches deep mulch layer at
approximately three feet in diameter, and six inches away from the trunk of the tree to reduce rot.
If trees are damaged due to herbivory, HELIX will install protective cages as a physical barrier or cover the
trunk's surface area with Miller's Hot Sauce as an herbivore deterrent. In the case a disease, damage, or
impaired health that can be remedied by a physical or chemical treatment, HELIX will communicate the
health effect and preventative measure to the City and implement the protective measure after approval.
HELIX will install up to 100 herbivory cages with T-Posts and chicken wire at a 4-foot diameter.
HELIX will analyze the data of survivorship and tree height in Year Two to identify areas where mortality and
lack of height is most present on -site and where robust trees are commonly found. HELIX will install willows
closer in wetter portions of the site, such as the northeastern area and in the channel going through the
southwestern portion of the Project site. Cottonwoods will be installed in drier portions of the project area
compared to the willow planting locations, as cottonwoods requires less water. Trees will be spaced
accordingly to reduce competition for water, sunlight, and nutrients. Because the project is approaching
Years Two and Three, timing supplemental planting while the irrigation is still operating is essential aide in
successful roots establishment. HELIX will install up to 50 replacement trees in February and March each
year as part of this scope of work. Additional trees will be planted at the cost provided in the Cost File.
Output: Quarterly monitoring visits by the biologist will identify maintenance and tree care and replacement
needs that will be outlined in a monitoring report. HELIX crews will implement biologist recommendations
to ensure success criteria are met, including herbivory and insect deterrents, tree replacement, and non-
native removal within the tree well.
Task 3- Management of Non -Native Plants — HELIX will treat and remove non-native plants on -site
through mechanical, hand, and herbicide application with a not -to -exceed non-native cover goal of 10%.
Sub -task: Weeds will be carefully treated using appropriate herbicide only after approval from the City. In
areas where chemical control is utilized, the intent is to treat weeds before they reach a mature state where
seeds will disperse. Any rain or high wind (exceeding 10 miles per hour) prevents the application of
herbicide. HELIX employs licensed applicators with current and active licenses in both Categories B and F
and HELIX is a licensed Pest Control Business.
If weeds have already established seed heads, either the seed head or the entire plant will be removed
mechanically or by hand and disposed of outside of the restoration area. HELIX staff are trained in native
and non-native species identification in Santa Clarita. Additionally, staff undergo annual trainings, such as
"Plant of the Week" and "Weed of the Week". In these trainings, HELIX personnel are tested on
identification skills through hands on and multiple-choice criteria. HELIX managers and monitors will train
employees on species found on -site and monitor maintenance to provide quality control while on -site.
Crews will be prepared to conduct maintenance activities and are equipped with equipment and materials
needed to perform weed abatement. Herbicide application equipment will be properly stored, and
equipment shall include backpack sprayers, spill kits, and Personal Protective Equipment. Hand weeding or
mechanical efforts will be performed as -needed and make use of line trimmers, mowers, gloves, hula hoes,
HELIX Response File I Page 6 of 28

Response File
shovels, picks, scissors, and hand loppers for cutting seed heads, as well as burlaps for disposing of non-
native material off -site.
Task 4 Site Maintenance. HELIX will maintain the site's T-Post perimeter around the Project and the
delineator between the two Project areas. HELIX will also remove man-made debris in the work area.
Sub -task: HELIX will monitor the perimeter of the project for gaps where T-Posts are absent on -site. In
these areas, HELIX will install new t-posts to maintain the Project's boundary. Also, HELIX will remove man-
made materials and objects brought into the Project area, excluding homeless encampments which will be
reported to the City. Man-made materials will be placed alongside the City trail that runs south of the
Project area. HELIX will coordinate with the City on staging locations along trails for debris that will be
picked up by City crews. Upon completion of Year Five, HELIX will remove the Project's permitter and
delineator T-Posts, and HELIX will coordinate with the City whether they prefer to retain possession of the
T-Posts.
Output: A clearly demarcated project boundary using T-posts will be maintained during the Project, and
then removed at completion. Trash and other non -natural materials will be removed or placed alongside
the trail for City crews to pick up.
Task 5 Negligence and Vandalism. HELIX included $3,000 per year of owner's allowance for repairs
needed because of negligence or vandalism by other, as determined by the City. HELIX will work with the City for
any expenditure of this allowance. Normal wear and tear are not subject to this allowance.
Sub -task: To be determined based on as -needed work approved by the City.
Output: To be determined based on as -needed work approved by the City.
Task 6 Monitoring and Annual Reporting. HELIX will monitor and report on site conditions including
the 50 representative trees in Areas A and B (mitigation sites) annually during Years Two through Five.
Sub -task: Annual monitoring will occur Years Two through Five. During annual monitoring visits, the
following data will be collected for the 50 representative trees: species; overall tree performance rating
(rated 1 [poorest] through 5 [best]); tree height (measured to the nearest 1/10t" of a foot); trunk diameter
(measured to the nearest 1/101" of an inch, measured at six inches above the mulch surface or at breast
height [diameter at breast height (DBH)-54 inches above the mulch surface if the tree exceeds this height]);
vigor; and the presence of damage and/or disease. Additionally, all 980 trees within the mitigation sites will
be assessed for survivorship. During the annual monitoring visit, all plant and animal species observed/
detected will be noted, an assessment of percent cover of non-native species will be performed, and a total
of six photo stations will be monitored annually. Annual and quarterly monitoring data will be drafted into
an annual report to include information such as project background, monitoring methods, results,
conclusions and recommendations, plant and animal species lists, and tree evaluation data. An ISA Certified
Arborist will oversee and sign the report.
Output: HELIX will prepare a report summarizing the data collected during the annual monitoring visit as
described above. The report will also include a summary of whether the restoration effort is progressing and
meeting the required success standards. The report will be submitted to the City each year by December
31 st.

4. Schedule
HELIX project managers and supervisors monitor weather conditions to ensure crews are most effective in
meeting tree and non-native plant maintenance needs. HELIX has experience working in all types of weather
conditions and understands seasonal scheduling to prepare for upcoming maintenance events.
Furthermore, late winter season rain events followed by warm weather are the catalysts for new weed cycles in
winter and spring. HELIX personnel will be tracking these events and working them into the schedule for
watering and weed control by the season.
Seasonally Driven Maintenance Schedule
Year Round: Pest control, irrigation system maintenance, and herbivory protection.
Summer to Fall: Weeding and irrigation system water increase, and repair.
Winter: Replacement planting, irrigation system water reduction and turn off system during rain
events; non-native grasses begin emerging (fusillade application).
Spring through Summer: Weed abatement, and irrigation system maintenance.
Irrigation Schedule

5. Program Management
HELIX has a depth of qualified personnel whose experience working on similar projects has led to a specific
skillset and systematic approach to completing tasks like those in the RFP Scope of Work. Habitat mitigation
maintenance requires a team with experience and expertise in managing these types of projects, in order to
plan for, schedule, implement, and report on work effectively to meet tree mitigation and non-native plant
cover goals while doing so at manageable costs. Our approach to completing maintenance relies on five steps
that we have tailored over years of experience on mitigation projects.
Program Management System Steps
1) Develop site -specific plans, maps, and reporting tools.
2) Ensure operation excellence by providing skilled staff, supplies, and equipment to perform
maintenance efforts safely and effectively.
3) Monitor weather conditions and seasonally -driven events.
4) Coordinate schedule and activities regularly with the project team and City.
5) Perform and report on work activities.
Step 1 requires project managers and biologists to formulate site -specific plans and upload data into software
applications such as Collector to be used in the field. Reporting tools include Survey123 forms that will collect
and store data from maintenance and monitoring visits. By developing and standardizing this information at the
beginning of the project, communication is effective, and information flows freely and accurately across the
project team.
Step 2 requires systematic training and communication of team members on the project goals. HELIX project
managers, monitors, and foreman will communicate daily via phone calls and emails to ensure work is
performed according to schedule and scope. Crews will be constantly trained on native and non-native plant
species, proper planting and maintenance techniques, site boundaries, irrigation system operation, and other
information required for the successful completion of maintenance program events.
Step 3 requires managers and monitors to track weather conditions, and the potential for those conditions to
effect the project. Drought, fire, and heavy rainfall events all have the potential to disturb progress of the trees
or create conditions that require maintenance needs, such as non-native removal or erosion repair. HELIX tracks
these conditions closely and changes schedules accordingly to ensure that progress success is met. The ability to
quickly respond to these site -altering events is often the most critical part of a successful maintenance program.
Step 4 requires coordinated scheduling prior to, during, and after each maintenance and monitoring event.
Before each maintenance event, the project manager will send a detailed email including maps and scope of
work for the crew to perform the next day. This direction is based on information that the crew has reported as
a result of the most recent work, or similar reporting from a manager, biological monitors, or the City staff,.
HELIX will work closely with the City during scheduling to ensure project needs are addressed.
Step 5 requires timely and effective completion of the scheduled work, and confirmation through reporting.
Following the completion of work, the crew will provide a daily report using two software applications. First,
they will distinguish work area and activities in the Collector app, which shows specific locations on a geo-
referenced map application. Secondly, they fill out a Survey123 application form, which is considered their main
daily report. Broken down by task, the foreman will list the specific acres and basic description of work

performed. Other important information provided on the daily report includes the date, names of crew
members, hours and crew members per task, herbicide use, non-native species observed, safety concerns,
major equipment used, and general site concerns.
HELIX's project managers will use the information in the daily reports to track progress, herbicide use, and time
between treatments at the project. Since the application of this tool provides specific information on given
areas, it allows for faster identification for areas of concerns, and it can lead to the discovery of certain trends
within areas that would be otherwise difficult to detect.
HELIX's project managers and senior management are highly effective at tracking schedules and implementing
measures to ensure projects are completed within established budgets and scheduled milestones. The proposed
project schedule is based on the Scope of Work outlined in the RFP is provided in the previous Section 4.
Schedule.
