QUALIFICATIONS
In-house services provided by HELIX include CEQA and
NEPA document preparation; regulatory permitting;
biological and aquatic resource assessments; arboriculture services; archaeological resources investigations; historic resource evaluations; acoustical/noise studies; air
quality/GHG analyses; visual resource assessments; land use and planning services; public engagement; mitigation monitoring and compliance; landscape architecture; and
GIS mapping and analyses. Our expertise in helping clients comply with codes and regulations addressing these topics comes from our extensive experience navigating the
complex regulatory environment.

Our staﬀ have extensive experience helping public and
private clients across various sectors navigate the
complexities of complying with local, state, and federal environmental laws and regulations. They have
implemented all aspects of the environmental process and regularly employ strategies to minimize delays and manage costs. Our staﬀ are trained to assist clients in determining the appropriate environmental documentation and review
process for each project. Our experience with
environmental processing also includes preparing and

HELIX also has extensive experience providing environmental training to contractors and other project personnel to help ensure that project requirements and protection measures are explained before construction and as construction progresses.

CONSULTING EXPERTISE
Aesthetics We oﬀer several HELIX staﬀ who are experienced in preparing Visual Impact Assessments (VIA) that evaluate the visual impacts of a given project on the environment, including the potential for degradation of scenic views, view blockage, and related issues of light, glare, and shadow impacts. As a ﬁrst step, HELIX staﬀ often help determine viewsheds and key observation points from which to evaluate visual impacts. Our capabilities range from computer-generated “before and after” simulations of a project to narratives of potential visual impacts. Measures to reduce potential visual impacts are identiﬁed as necessary and may include suggestions related to site layout, bulk and scale of buildings, lighting, and landscape.

Agriculture/Forestry Resources HELIX provides technical and environmental evaluations of agricultural resources and related issues under the State CEQA Guidelines. This includes preparing agricultural technical studies to assess existing and potential agricultural resources, evaluate project-related impacts to and from these resources, and identify potential mitigation options where appropriate. HELIX is also experienced in preparing agricultural assessments under the California Department of Conservation Land Evaluation and Assessment (LESA) Model guidelines and Farmland Conversion Impact Rating assessments under the federal Farmland Protection Policy Act (FPPA).

Air Quality/Greenhouse Gas Studies/Energy & Climate Action Plans HELIX prepares air quality impact and air pollution analyses, including dispersion modeling, that meet CEQA/NEPA requirements. Our staﬀ is proﬁcient in regional air authority regulations and the conformity requirements of the Clean Air Act. HELIX has been preparing and conducting emissions analyses in this rapidly changing ﬁeld following the evolving requirements for global climate change and GHG emissions accounting. We also prepare Climate Action Plans and Energy Action Plans, which guide community eﬀorts for reducing GHG emissions.

Biological Resources, Urban Forestry, and Regulatory Permitting HELIX’s skilled biologists, botanists, arborists, and wetland scientists have the range of expertise needed to assess biological resources found within the City. HELIX conducts biological resource assessment surveys, vegetation community mapping, and other biological analyses to identify the likelihood of the occurrence of special-status species or habitats, make recommendations for further studies, and/or identify mitigation measures or permits that may be required.

HELIX’s biologists prepare reports summarizing biological resources based on the preliminary information assembled about biological resources in Los Angeles County and the data collected in the ﬁeld. Our reports

7 CITY OF SANTA CLARITA| On-Call Environmental Planning Services contain information about the project site and the limit of study, baseline information (e.g., soils, California Natural Diversity Database, etc.), potentially occurring special-status species, and the ﬁeld survey results.

HELIX also provides comprehensive tree management and urban forestry services. Our International Society of Arboriculture (ISA)-certiﬁed arborists are also ecologists and regulatory experts with extensive experience in local, regional, state, and federal regulatory compliance, and we use this expertise to coordinate closely with our clients to avoid and minimize project impacts on arboricultural resources. To help land managers and project applicants protect tree resources (on project sites and other locations such as urban areas or in preserved/protected areas) and/or better manage the health of their trees, our arborists use high-precision Global Positioning System (GPS) units to map arboricultural resources, create GIS-based tree inventories, and develop comprehensive tree protection and mitigation plans for long-term care.

HELIX also has extensive experience in the delineation of aquatic resources according to the 1987 U.S. Army Corps of Engineers Wetland Delineation Manual, the Arid West Supplement, and applicable local, state or federal wetlands regulations. We also track evolving permit requirements, including the 2023 U.S. Supreme Court ruling on the Clean Water Act (Sackett v. Environmental Protection Agency). We map wetlands and other waters of the U.S. and the state and facilitate the veriﬁcation of aquatic resources delineation maps, both preliminary jurisdictional determinations and approved jurisdictional determinations with the U.S. Army Corps of Engineers (USACE).

Finally, our experience includes working closely with regulatory and other resource agencies, including the U.S.

Fish and Wildlife Service (USFWS), California Department of Fish and Wildlife (CDFW), Regional Water Quality Control Board (RWQCB), and the USACE in formal consultation and permitting processes. As part of on-call contracts, our staﬀ often responds to urgent and next-day requests, including support for pre-activity surveys, meetings, and monitoring needs. In emergencies, we can provide same-day service and help crews minimize environmental damage without hindering their ability to act.

Cultural and Tribal Cultural Resources HELIX
oﬀers a full range of cultural resources services
to support the CEQA and NEPA processes,
including cultural surveys, inventorying,
monitoring, archaeological studies, historic
studies, historic structure assessments, Section
106 consultation, Historic American Buildings

We supplement our team with Bargas to provide paleontological consulting peer review, technical reporting, and monitoring services.

Hazards & Hazardous Materials HELIX planners routinely address potential project impacts related to hazards and hazardous materials in accordance with Appendix G of the State CEQA Guidelines. Our subconsultant, Geocon, also oﬀers extensive experience assisting clients in complying with federal, state, and local laws and regulations and provides multi-disciplinary environmental engineering services, including environmental assessments, soil and groundwater investigations, remediation engineering, regulatory compliance, and risk- based corrective action studies to support the CEQA and NEPA processes.

Hydrology & Water Quality Our team regularly assesses impacts associated with hydrology and water quality, including impacts related to ﬂooding, surface water quality, groundwater, and drainage in accordance with Appendix G of the State CEQA Guidelines. With technical support provided by PACE, the HELIX team oﬀers the full suite of skills needed to assess both the construction and operational impacts of proposed infrastructure and development projects.

Land Use/Planning HELIX’s environmental planning staﬀ includes experts who assess potential land use compatibility issues related to land development projects. Several of our specialized planners, including the assigned program manager, are active American Institute of Certiﬁed Planners (AICP) members. HELIX is experienced in evaluating the long-term compatibility of adjacent uses, short-term construction impacts related to noise and dust, and potential long-term and cumulative issues such as visual character, noise, and odor are also considered.

Noise Assessments HELIX's in-house acoustical specialists prepare technical studies that help clients comply with applicable local, state, and federal environmental laws and regulations, including local noise ordinances, CEQA, NEPA, and the state and federal Endangered Species Acts. We frequently conduct studies predicting equipment, construction, and/or transportation noise impacts on sensitive uses, such as residential developments or recreational areas. In addition to evaluating the impact of noise on humans, HELIX specializes in evaluating noise impacts on wildlife, especially threatened and endangered bird species. We provide monitoring services to ensure a project's speciﬁed noise level goals are achieved.

Population/Housing For both public and privately initiated projects, HELIX environmental planners assess whether a project would induce substantial population growth directly or indirectly. Direct impact analyses often consider adopted local and regional planning documents and projections. In contrast, indirect impact analyses frequently address whether the project will extend roads or other infrastructure that could induce growth. Our planners will also address whether the project could displace people or require the construction of replacement housing elsewhere. HELIX specialists and planners conduct socioeconomic, economic, and community impact studies to support NEPA documentation. This includes but is not limited to Community Impact Assessments (CIA), Health Impact

9 CITY OF SANTA CLARITA| On-Call Environmental Planning Services Assessments (HIAs), and Environmental Justice Impact Assessments in compliance with NEPA and/or local Sustainable Communities Strategies.

Public Services/Utilities/Recreation In addition to working closely with public service, parks and recreation, and public utility providers to assess the impacts of their proposed projects pursuant to CEQA and NEPA, HELIX is well-versed in coordinating between cities and public agencies, utilities, civil engineers, and construction contractors to determine the on- site and oﬀ-site public service and utility needs for public and privately initiated development projects and our in-house landscape architects bring a unique understanding of park and recreational design and operational activities. Once we understand the breadth of the project’s public services, utilities, and recreational components, HELIX staﬀ can assess the short-term, long-term, direct, and indirect impacts of the proposed activities. These often include impacts associated with lighting, air quality, GHG emissions, noise, and cultural and biological resources.

Transportation HELIX is an industry leader providing a wide range of environmental consulting services for projects involving all modes of transportation. Our team brings extensive experience coordinating directly with Caltrans, regional transportation and transit agencies, and local jurisdictions on local transportation projects, including those with federal funding. HELIX has worked with the Federal Railroad Administration (FRA), Federal Transit Administration (FTA), and Federal Highway Administration (FHWA; directly and via Caltrans Department of Local Assistance) as federal lead agencies under NEPA.

Together with our subconsultant, LLG, we also analyze the impacts of development projects relative to transportation. Speciﬁcally, LLG provides local mobility analyses and vehicle miles traveled (VMT) assessments for projects that include complex multi-modal components, intricate access and circulation networks, expansive study areas with multi-jurisdictional forecasting requirements and impact criteria, a wide array of land use types, and mixed-use development programs. They deeply understand VMT assessments and methods to reduce signiﬁcant VMT impacts, including preparing transportation demand management programs.

Wildﬁre To assist in impact analyses related to wildﬁre hazards and evacuation, HELIX has included Firewise 2000. Firewise 2000 specializes in developing professional wildﬁre risk assessments, Fire Protection Plans, and Fuel Modiﬁcation Plans for residential and commercial developments, individual homeowners, and public land management agencies. Established in 1997, their staﬀ includes a registered forester, Certiﬁed CEQA Wildland Fire Consultants, retired certiﬁed arborist, ﬁre prevention specialists, and retired ﬁre suppression operations personnel who are recognized experts in developing reports detailing wildﬁre risk and associated ﬁre hazards.

CITY OF SANTA CLARITA

HELIX has provided environmental services to the City for multiple projects under direct contracts with the City and through private development contracts, with the City serving as the lead agency. Recent projects include:
+
Newhall Ranch Road Bridge & McBean Parkway Environmental Mitigation HELIX conducted environmental mitigation for road widening projects in the City. Tasks included non- native plant removal, fencing, irrigation installation, and tree planting as part of the installation phase throughout a 7-acre project area. The streambed restoration project is located within the Santa Clara River and San Francisquito Creek areas, covered by an umbrella set of environmental authorizations known as the Natural River Management Plan. A joint Environmental Impact Report (EIR)/Environmental Impact Statement (EIS) and master permits, which include a USACE 404 permit, CDFW Streambed Alteration Agreement, and Los Angeles RWQCB Waste Discharge Requirements, covers much of the Santa Clara River and its tributaries within the City of Santa Clarita. The impacts of the Newhall Ranch Road Bridge are being mitigated by removing and monitoring exotic, highly invasive vegetation, such as giant reed and salt cedar, in three locations. HELIX biological monitors performed a tree inventory and assessment for a subset of the mitigation trees in the 7-acre mitigation site. The assessment determined existing conditions in relation to performance standards. Tree height, diameter, canopy spread, and GPS location were collected for each tree. Overall tree health, as well as the presence of disease/pathogens and damage, were also assessed. HELIX also conducted non-native plant removal, fencing, irrigation installation, and tree planting. Approximately 1,000 cuttings were installed and irrigated using drip irrigation. HELIX continued maintenance for one year under this contract, which required re-planting, irrigation repair, and non-native plant removal. HELIX ﬁeld biologists also provided vegetation mapping, prepared environmental awareness training materials, conducted surveys for sensitive wildlife, and conducted monitoring to help contractors avoid sensitive biological resources. Following the ﬁnal approval of this contract, the City awarded HELIX a separate long-term maintenance contract for an additional 4-year period.

+ Creekside Commons HELIX provided environmental services for a four-acre aﬀordable housing development in the City. Tasks included CEQA Class 32 Categorical Exemption, development of construction and operational period criteria pollutant and GHG emissions inventories, biological resources, cultural resources, air quality technical reports, and the preparation of a noise technical report incorporating analysis of construction and operational noise, as well as exposure of the project to oﬀ-site traﬃc noise. A particular focus was analyzing noise from the adjacent Metrolink track and assessing potential impacts to the open space located to the east. Work performed for CRP Aﬀordable Housing & Community Development, with the City as the lead agency.

+ Bouquet Canyon Road Project HELIX provided biological entitlement and regulatory permitting services for a 54-acre residential development in the City. HELIX prepared due diligence documentation identifying biological constraints and recommended solutions before the client acquired the project site.

Upon property acquisition, HELIX managed biological and cultural resources surveys, prepared biological technical reports, and processed regulatory permit applications for the project. HELIX also worked closely with the project geotechnical engineer to identify and avoid known biological constraints, including jurisdictional waters, rare plants, and nesting birds, as part of geotechnical ﬁeld investigations on the project site. A qualiﬁed biologist then monitored the geotechnical work, making ﬁeld adjustments to access routes and boring locations to help avoid adverse eﬀects on biological resources. HELIX developed on- and oﬀ-site mitigation approaches to compensate for impacts on jurisdictional streambeds and oak trees, working with its in-house habitat restoration staﬀ, local mitigation banks, and local conservation agencies. HELIX recently led pre-construction surveys on the project site as required by the project regulatory permits and is leading the biological monitoring and on-site mitigation implementation. Work is being performed for Integral Communities with the City as the lead agency.

+ Via Princessa Park CEQA & Environmental Studies The City is proposing to construct a park and regional inﬁltration facility in an area of vacant City-owned land along the south bank of the Santa Clara River in the Canyon Country community. The project will include athletic ﬁelds with sports ﬁeld lighting, park amenities, a pedestrian and vehicle railroad undercrossing, a subterranean regional stormwater inﬁltration facility, buried bank protection, a storm drain culvert extension, and restoration of the existing drainage channel. HELIX performed biological surveys for the project, including a general biological survey and vegetation mapping, a jurisdictional and wetland delineation, rare plant surveys, least Bell’s vireo surveys, Crotch’s bumble bee surveys, burrowing owl surveys, and a tree inventory.

HELIX worked closely with the project design team to minimize jurisdictional impacts. HELIX prepared the biological technical report and processed regulatory permit applications for the project. Work was performed as a subconsultant, with the City as the lead agency.

CITY OF IRVINE
As-Needed Environmental Services

HELIX has been providing the City of Irvine with as-needed environmental services since 2016. Services include the preparation of technical studies and CEQA-related documents, as well as peer review of technical studies and CEQA documents prepared by others. Representative task orders include:
+ Irvine Planning Areas 12 and 40 General Plan Amendment/Zone Change Peer Review HELIX performed a peer review of the IS for the Planning Areas 12 and 40 General Plan Amendment and Zone Change to revise the land use designations from industrial and commercial to medium-high-density residential. The total aﬀected area was approximately 33 acres. The project application was subsequently withdrawn.

When the application was later re-submitted, the HELIX team performed peer reviews of an applicant- prepared EIR Addendum, biological resources assessment, Phase I ESA, and geotechnical investigation.

+ Irvine Amphitheater at Great Parks Neighborhood HELIX completed a peer review of several technical studies prepared by others, managed subconsultants in their peer reviews of technical studies prepared by others and prepared an Addendum to a Supplemental EIR to evaluate the construction and operation of a temporary amphitheater. The proposed project involved using a temporary amphitheater for three years within an undeveloped portion of the park at the decommissioned Marine Corps Station El Toro.

Key issues included traﬃc, light, and noise impacts on future residential uses, as well as a future wildlife corridor. HELIX prepared a second Addendum to the Supplemental EIR to evaluate the construction and operation of a permanent amphitheater and conducted air quality/GHG and noise impacts modeling to support the Addendum.

+ Bommer Canyon Community Park HUD NEPA Checklist HELIX prepared a HUD NEPA Checklist for rehabilitating the three-acre Cattle Camp Area in Irvine's Bommer Canyon Community Park. The project included improvements to increase park access. HELIX's initial review anticipated that renovating the existing structures to be Americans with Disabilities Act (ADA)-compliant would qualify for a NEPA Categorical Exclusion under HUD's NEPA guidelines. Qualifying for the NEPA Categorical Exclusion was contingent on ﬁnding that the renovations would not conﬂict with Section 106 of the National Historic Preservation Act (NHPA) or the federal ESA. HELIX prepared the EA Determinations and Compliance Findings for HUD-assisted Projects and HUD NEPA Checklist and received concurrence from the California State Historic Preservation Oﬃcer regarding the ﬁnding that the Cattle Camp facilities are not considered signiﬁcant historical resources.

+ Hollandia Dairy Farm/Facility Odor Remediation Plan Peer Review Hollandia Dairy is a processing facility that produces dairy products on site, including homogenizing and packaging milk, ice cream, and seasonal milk products. To comply with the requirements of the Vallecitos Water District and the Encina Wastewater Authority, the dairy is required to pretreat wastewater eﬄuent from the processing facility before it is discharged into the sanitary sewer system. Since December 2023, the City of San Marcos and the San Diego Air Pollution Control District (APCD) have received consistent complaints about odors from the facility. To address these complaints, the City of San Marcos initiated an investigation to determine if a violation of the City’s odor nuisance ordinances had occurred, conﬁrming the presence of odors oﬀ- site. To resolve the code compliance issues, the dairy prepared a Remediation Plan. HELIX was tasked with conducting a third-party review of the dairy’s odor remediation plan and providing recommendations on a quantitative method the City of San Marcos can use to evaluate the eﬀectiveness of odor mitigation eﬀorts.

Additionally, as a consultant on the City’s Qualiﬁed Consultant List, HELIX has prepared technical reports and CEQA documents for privately initiated development projects proposed in the City, including the following recent project.
+ Home2 Suites Hotel San Marcos HELIX prepared technical reports and an Addendum to a 2018 IS/MND to document how the modiﬁed project was adequately addressed in the prior IS/MND.

PROGRAM MANAGEMENT & QA/QC
HELIX has developed a project management system based on over 33 years of leading or participating in more than 350 on-call service contracts. Once an agreement is issued and signed, the master on-call contract, scope of work, and budget are all available for any staﬀ to review at any time in the digital project folder in the HELIX system.

Yara Fisher, AICP, will serve as the program manager and the City's primary point of contact. When the HELIX program manager receives a task order request from the contract owner, they work to determine the required services and assign an appropriate task order manager based on speciﬁc needs. The task order manager prepares the task order scope and budget with input and review by the program manager and the client. The scope of work is as detailed as possible so that both the client and HELIX clearly understand what is and is not included. The budget is prepared to address the task order scope, incorporating senior staﬀ for those tasks that are more complex and less senior staﬀ for more straightforward tasks to minimize costs. Once HELIX receives authorization to proceed, work begins, and any additional information HELIX needs is requested. This phase can involve conference calls, lists of information needs, in-person kick-oﬀ meetings, ﬁeld meetings, and other approaches to ensure the work is completed eﬃciently and accurately.

To implement and manage the scope of work and budget, the task order manager provides assignments that include the approved scope, the assigned budget/hours, the schedule for completion, and other detailed directions, such as available background information, client expectations, and report format requirements. The set deadlines consider that quality assurance reviews are required before submitting any work to the client.

HELIX’s project managers are highly eﬀective at tracking schedules and implementing measures to ensure projects are completed within scheduled milestones. To achieve a successful outcome, HELIX prepares clear, tailored schedules for each project that specify key milestones for deliverables and connections between tasks. If potential bottlenecks are identiﬁed, we provide solutions to avoid schedule delays. We create task schedules using Microsoft Project, which indicates task predecessors, concurrent tasks, and critical milestones. If certain tasks take longer than expected, we look for ways to expedite other tasks to keep the project on track. We build in extra time in the planning stage as a contingency to address unforeseen delays. These management and scheduling tools result in eﬃcient and successful completion of project tasks.

HELIX also employs several management tools tailored for the completion of ﬁeld-oriented tasks. A successful day in the ﬁeld relies on preparation in the oﬃce. Before any ﬁeld activity, HELIX staﬀ review the scope of work and budget. Any questions are vetted well before the actual ﬁeld visit, and the ﬁeld team prepares an action plan. Preparation for a ﬁeld visit may include collecting ﬁeld maps (both hard and digital copies), discussing access to the site, evaluating any safety-related items, and consensus regarding data collected and how it will be recorded. Following each ﬁeld activity, associated staﬀ reconvene to ensure that everyone is safe and the required data has been successfully collected in the desired format. The technical staﬀ processes ﬁeld data in the desired format and passes it to the task order manager for review.

As a project moves forward, HELIX uses Deltek Vantagepoint, an integrated cost tracking and invoice billing software. This system incorporates the agreed-upon billing rates for the contract, allowable expenses, and subconsultant budgets. Staﬀ enter their time daily, allowing managers to track project budgets in real time and quickly react to any issues. Invoices are customized to provide essential information, including the names and billing rates of each assigned staﬀ member, the nature of the work completed, the percentage of work completed, and the remaining budget. Deltek Vantagepoint has a robust accounts payable tracking system, an electronic invoice tracking system, and an electronic accounts receivable system that allows for detailed project

21 CITY OF SANTA CLARITA| On-Call Environmental Planning Services budget management. HELIX has customized reports that enable a project manager to track and provide information to the client on speciﬁc billing aspects of the project with high-level detail and without delay.

Customized invoice forms can also be created. HELIX project managers can create backup informational reports and graphics to accompany invoices often needed on construction and maintenance projects to verify unit billings and work completion. All invoices and expenses are reviewed and approved by the assigned project manager in our online system. Invoices for each task order are reviewed by the task order manager and the program manager. A summary of services provided during the month and the status of task order budgets are provided in a format preferred by the client.

Quality Assurance/Quality Control (QA/QC) Process To ensure the high quality of our analytical and documentation processes, HELIX has developed a comprehensive QA/QC program that applies to our activities and work products. The fundamental objectives of HELIX's QA/QC program are to ensure that work products fulﬁll the scope of services and that the City's speciﬁc needs are both fully deﬁned and met. HELIX's quality assurance policies are integrally connected to our project management approach. Our quality assurance approach also integrates elements such as following the appropriate "style guide" for each work product, either using our template or an agency's, which ensures a high-quality and consistent look and feel to our work products.

All HELIX-written products are reviewed by the task manager and a separate quality control (QC) reviewer. The QC reviewer is typically the program manager but may also be another senior staﬀ person (e.g., principal planner or senior scientist). The assigned task manager will ﬁrst thoroughly edit work products completed by technical staﬀ. Then, the assigned QC reviewer reviews and edits the document. The task manager will then ensure all revisions and edits are made before submission.

No draft document will be submitted to the City without this QC review. Documents are reviewed for content, grammar, spelling, format, and accuracy. Appropriate signiﬁcance guidelines, acronyms, project naming conventions, etc., are agreed upon upfront with the City and communicated to the HELIX staﬀ to ensure consistency throughout the project documentation. A technical editor also reviews and edits reports for writing clarity, spelling, word use, grammar, etc. The technical editor and/or a word processor also review the ﬁnal product for formatting, including page endings, table formats, and heading levels. The technical editor also ensures that documents intended for public distribution are consistent with the accessibility requirements of Section 508 of the Rehabilitation Act (29 United States Code Section 794d) and California Government Code Section 7405 et seq. Graphic work products, such as maps, are checked by a senior GIS specialist and the assigned program manager to ensure that graphics portray the required information in an attractive format; information sources are clearly identiﬁed; an accurate scale and north arrow are provided; legible and informative labels are used in the map and its legend; color coding or patterns (if used) are distinguishable; ﬁgure and report titles are provided and are accurate; and the map fulﬁlls the scope of work and adheres to the City's speciﬁcations and requirements. A ﬁnal check of the ﬁnished hard copy and/or electronic ﬁles is also conducted before a submittal goes out our door. This multiple-step internal QA/QC system will ensure that submitted documents and support materials are of the highest quality and meet the City's and other applicable agency requirements and expectations.
