Subject: Biological resources letter report for the approximately 0.68-acre parcel located at 1530 Scenic Drive located in the City of Pasadena, Los Angeles County, California Dear Trenman Yau:
Bargas Environmental Consulting (Bargas) is pleased to provide this biological resources letter report for the approximately
0.68-acre parcel located at 1530 Scenic Drive (hereafter, Project) located in the City of Pasadena, Los Angeles County, California. As described herein, no special status biological resources were observed on or in the vicinity of the property during the survey, and none have more than a low potential to occur on or in the vicinity of the site. Further, the proposed Project is unlikely to have an effect on wildlife movement and is not located within or adjacent to preserved areas or Significant Ecological Areas identified by the County of Los Angeles. Accordingly, the site has no value as habitat for endangered, rare, or threatened species. The following letter details the resources analyzed during desktop analysis and methods used during the field survey.
Project Location & Description
The Project is a single-family residential project located at 1530 Scenic Drive (APN 5704025002) in t he City of Pasadena, Los Angeles County, California. The P roject is a 2 -story home with an area of approximately 4000 square feet house , including a 2,800 square foot basement garage. The parcel size is approximately 0.68-acre.
Methods
This report is informed by data from a desktop analysis of the literature and numerous resource databases, as well as the field survey, the methods for which are described below.
Definitions
This report will use the following definitions for areas referred to herein:
• Project site: The Project site is defined as the 0.68 acres being analyzed for Project entitlements. • Biological Study Area: The Biological Study Area is defined as the Project site and a 250-foot buffer. This is the area within which biological resources were fully analyzed. • Regional Study Area: The Regional Study Area is defined as the Project site and a 3-mile buffer. The Regional Study Area was used as the basis for determining special status biological resource records for consideration in this report.
Desktop Review
Prior to conducting the field survey, Bargas conducted an initial review of literature and data sources to characterize the biological conditions and to compile records of sensitive biological resources that could potentially occur in the Biological Study Area. The methods used for this analysis are described below.

Biological Setting
The biological setting includes terrain, hydrology, soils, land uses, and other features that support or inhibit biological resources in an area. In order to better understand the biological setting of the project, the following resources were reviewed in detail:
• US Fish and Wildlife Service’s National Wetlands Inventory to determine if surface waters and wetlands have been mapped on or adjacent to the Biological Study Area.
• US Geological Survey’s National Hydrography Dataset to determine if hydrological features have been mapped on or adjacent to the Biological Study Area.
• US Department of Agriculture National Resource Conservation Service Web Soil Survey to map and describe soil(s) within the Biological Study Area.
• Google Earth Pro aerial map images of the Biological Study Area, including historical aerial images.
Special Status Species & Habitats
It is important to create a well-defined list of habitats and species that could reasonably be expected to occur on the Project site in order to analyze potential Project effects on biological resources effectively. The following describes how the list of potentially-occurring special status biological resources was assembled.
Data Sources
Species and habitat occurrences were queried from the following resources:
• US Fish and Wildlife Service’s Information for Planning and Consultation portal (IPaC) for a list of federally listed species and designated critical habitat recommended for impact analysis consideration, based on an upload of the Biological Study Area limits.
• California Department of Fish and Wildlife’s California Natural Diversity Database (CNDDB) for special status species and habitat records within the Regional Study Area. • California Native Plant Society’s Inventory of Rare and Endangered Plants for a list of special status plant species occurrences within the USGS 7.5-minute quadrangles that overlap the Regional Study Area.
Special Status Designations Considered
A variety of agencies and respected non-profit organizations assess the conservation status of plant and wildlife species, however, not all are applicable to this report. The following special status designations were considered when determining special status species to be discussed in this report:
• Federal Status: Species listed as Endangered (FE) or Threatened (FT), as well as species Proposed as Endangered (FPE), Proposed as Threatened (FPT), Proposed for Delisting (FPD), and Candidates (FC) for listing under the Federal Endangered Species Act.
• California Status: Species listed as Endangered (CE) or Threatened (CT), as well as species that are Candidates for Endangered (CCE) status, Threatened (CCT) status, or Delisting (CCD) under the California Endangered Species Act. Also considered are species listed as Fully Protected (FP) and Species of Special Concern (SSC). • CNPS Status: All California Rare Plant Ranks (CRPR) maintained by the CNPS Inventory of Rare and Endangered Plants.
• Vegetation Communities: All vegetation communities mapped by the CNDDB.

Occurrence Potential
Following the desktop review, field surveys, and habitat analyse s, Bargas assessed the potential for the occurrence of special status species in the B iological Study Area. Biological conditions (vegetation communities, wildlife habitats, disturbances, etc.) and the habitat and life cycle requirements of special status species identified for analysis in the desktop review were considered. “Recent” occurrences are defined as observed within the past 30 years. Based on these considerations, species were assigned to the following categories:
• Present: Species is known to occur in Biological Study Area based on recent surveys, CNDDB (within 30 years), or other records.
• High: Species with known recent recorded occurrences/populations near the B iological S tudy Area and highly suitable habitat occurs within the Biological Study Area. Highly suitable habitat includes all necessary elements to support the species (e.g., elevation, hydrology, soils, cover, habitat type, food resources). • Moderate. Species with known recent recorded occurrences/populations near the B iological S tudy Area; however, habitat within the B iological S tudy Area has been moderately disturbed, fragmented, or is small in extent. Moderately suitable habitat includes several elements to support the species (e.g., elevation, hydrology, soils, cover, habitat type, food resources). Furthermore, moderately suitable habitat may also be located at the edge of the species’ range, or there are no reported occurrences nearby. • Low. Species with few known recent recorded occurrences/populations near the Biological Study Area and habitat within the Biological Study Area is highly disturbed or extremely limited. A low potential is assigned to annual or perennial plant species that may have been detectable during a focused survey in the appropriate blooming period but was not found; however, small populations or scattered individuals are still considered to have a low potential to occur. Additionally, species for which poor-quality habitat may support the species within the B iological Study Area, but the reported extant range is far outside the Biological Study Area and/or any species observations would anticipate being migratory (i.e., not likely to reproduce within the Biological Study Area). • Presumed Absent/No Potent ial. Focused surveys were conducted and the species was not detected, or the species was found in the desktop review, but suitable habitat (soil, vegetation, elevational range) was not found in the Biological Study Area, or the Biological Study Area is not within the known geographic range of the species.
The potential for bird species were further distinguished into those that may: 1) nest within or near the Biological S tudy Area; 2) forage within or near the Biological Study Area; and/or 3) occur on or near the Biological Study Area only as transients during migratory flights or other dispersal events.
Field Surveys
Bargas biologists Jane Gao and Marcus England performed a reconnaissance-level biological survey on September 28, 2022, from 0815 to 0900h. The goal of the survey was to record all observations of plant and wildlife species and determine the suitability of habitats on the Project site for potential special status species. The Project site was examined on foot and by binoculars to view distant wildlife. Wildlife and plant species observed were recorded by hand in a field notebook.
General photos of Project site conditions were taken using an iPhone camera using the Solocator app.
Seasonal and temporal factors may have influenced species detected. The survey was conducted in September and may have missed potentially occurring migrants, breeding species, and other season -specific flora and fauna. In addition, the survey was performed during the day and was limited to diurnal wildlife species.
Survey dates, times, personnel, and weather conditions are summarized in Table 1 below.

Other Considerations
Wildlife Movement
Effects on wildlife movement are an important consideration when assessing the potential impacts of any project. At a small enough scale, any project or activity can potentially affect the movement of wildlife if any wildlife are present at all.
In general, however, the term “Wildlife movement corridor” means an area of habitat that is important for the movement of wildlife between larger habitat areas. Wildlife movement corridors are important for maintaining population levels and genetic diversity.

Wildlife require space to roam in search of food, shelter, mates, or for seasonal migration. Fragmentation of wildlife movement from human development can disrupt the normal flow of essential ecosystem functions. The extent of habitat movement requirements is dependent on the taxa and is crucial to the survival of many species. Overall wildlife movement has become restricted due to man -made barriers, such as roads, structures, development, walls or fencing, and even agricultural fields. It is particularly important to maintain habitat and landscape connectivity and wildlife movement between regional habitat blocks for wide-ranging and low-density mammalian carnivores that require a large home range for survival, including Bobcat (Lynx rufus), Coyote (Canis latrans), and Mountain Lion (Puma concolor).
The Project site is unlikely to be of importance to wildlife movement because of significant existing anthropogenic site disturbance to habitats and surrounding residential development. As such, the proposed Project would not significantly affect wildlife movement.
Nesting Birds
Birds – including native species protected by the Migratory Bird Treaty Act and California Fish and Game Code – have the potential to nest in nearly any environment, including those heavily altered by anthropogenic activity. On the Project site, trees and shrubs provide ample locations for potential nesting, although no nesting was observed.
Discussion
Any project resulting in ground disturbance has the potential to impact biological resources. However, this proposed Project is located in an established residential neighborhood. No special status species has more than a low potential to occur. Further, the proposed Project is unlikely to have an effect on wildlife movement and is not located with or adjacent to preserved areas or Significant Ecological Areas identified by the County of Los Angeles. It is recommended, however, that the following measures be taken:
• If construction occurs during the nesting bird season (February 1 to September 30), a nesting bird survey should be conducted within one week of construction initiation. If active nests of Migratory Bird Treaty Act- protected species are identified during the survey, and the surveying biologist determines that the nests could be impacted, the biologist should develop a written plan including measures to ensure the protection of nesting bird resources. • An arborist survey should be conducted if it has not been conducted already. The consulting arborist will map the location and health of native and non -native trees on the Project site and determine what mitigation (replacement) may be required if tree impacts are expected.
