1 Introduction
Dudek has prepared this Biological Resources Technical Report (BRTR) for the City of Glendora (City) for the Grand Estates (proposed Project or Project). The Project proposes to develop 12 new single-family residential lots and one lot for two private streets located on privately owned land within the City of Glendora, Los Angeles County, California.

The Project site includes several flood control easements within the northern portion of the property. Thus, the proposed Project also includes the installation of three debris basins (per Los Angeles County Flood Control Department requirements) and construction of a new access road within the northern portion of the property.

The purpose of this report is to: (1) describe the conditions of biological resources within the Project area in terms of vegetation, flora, jurisdictional waters and wetlands, wildlife, and wildlife habitats; (2) quantify potential direct and indirect impacts to biological resources that will result from the proposed Project; (3) discuss those impacts in terms of biological significance in view of federal, state, and local laws and City policies; and (4) discuss mitigation measures that will reduce significant biological impacts to a less-than-significant level consistent with federal, state, and local regulations, including the California Environmental Quality Act (CEQA). This BRTR presents the findings of several biological surveys conducted at the Project site by Dudek, including a general biological reconnaissance survey conducted on May 15, 2019, jurisdictional delineation update on July 18, 2019, focused special-status bird surveys from April to July 2019, focused special-status plant surveys conducted in May and July 2019, and a general biological reconnaissance survey conducted on January 22, 2022.

1.1 Project Location
The approximately 27-acre property is located on privately owned land at 950 North Silent Ranch Drive within the City of Glendora in eastern Los Angeles County, approximately 23 miles east of downtown Los Angeles, as shown on Figure 1, Project Location. The general Project area lies north of I-210, east of SR-39, and west of SR-57 bordered by the Cities of Azusa to the west, San Dimas to the east, Citrus, Covina and Charter Oaks to the south, and unincorporated Los Angeles County to the north. The Project area is in Township 10 North, Range 6 West, and Section 4 as shown on the U.S. Geological Survey (USGS) 7.5-minute Glendora, CA and Azusa, CA quadrangle maps (USGS 2018). The northern approximately 16 acres of the property is zoned Open Space - Natural and are designated as a “building restriction area”, and the southern approximately 11 acres is zoned for single-family residences.

1.2 Project Description
The proposed Project would develop 12 new graded pads and a Private Street in the southern section of the Project site. Each residential lot would accommodate custom home development at a future date. One existing home and its associated residential lot is also included within the Project boundaries. Although the ultimate timing and design of each residential home would occur at an unknown future date subject to economic market conditions and the buyer’s preferences, for the purposes of the impact evaluation within this IS/MND, the construction and long-term occupancy of the properties is assumed and analyzed. The existing single-family residence in the southwestern corner of the Project site would remain in place. As such, upon buildout, the Project site is expected to support a total of 12 residences, all of which would be located within the 11-acre southern section of the Project site, which is zoned for single-family residential use.

Item #8. Page 496

GRAND ESTATES PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT 8375 2 MARCH 2022
The approximately 11-acre southern section of the site would be developed with residential uses and the approximately 16-acre northern section of the site would remain as open space, with the exception of flood control.

The new lots would range in size from approximately 32,000 square feet to 20,000 square feet. The existing singlefamily residence is on a 86,010 square foot lot.

The Private Street would be constructed along the southeastern edge of the Project site, providing access to each residential lot. The street would be privately held by the Homeowner’s Association (HOA), which would be established for the proposed development, once the new custom homes are constructed and occupied. More specifically, covenants, conditions, and restrictions of the HOA would be approved prior to grading so that all hydroseeding, watering, maintenance of the HOA areas and the habitat restoration areas; additional mitigation requirements; and other conditions or approvals would be established prior to construction of the proposed Project.

The City would impose this as a condition of approval of the Tentative Tract Map. Entrance to the Project site would be gated, with a gate controller and turn-around located within the Private Street adjacent to Lots 13 and 14.

Flood Control Facility Improvements
The northern 16 acres of the Project site are zoned open space and would be designated as a “building restriction area.” No habitable structures would be constructed within the northern section of the Project site, except for the proposed flood/debris control facilities. The LACFCD determined that with implementation of the proposed Project, potential debris flows during rain events from the undeveloped hillside areas to the north of the site could not be adequately captured by the existing debris control structures, which are filled to capacity and no longer function as intended. Therefore, the existing three flood control/debris check dam structures would be removed and larger flood/debris control facilities would be constructed within generally the same location, to protect the new residential development from safety hazards associated with flooding and debris flow.

Each spillway inlet would be approximately 5 feet tall, would include a debris barrier rack to filter out large woody debris, and would connect to a 36-inch reinforced concrete pipeline that would connect to the storm drain system in the residential area below. An asphalt maintenance access road would be constructed to the north of the residential development and to the south of the inlets and the debris basin, to allow maintenance vehicles to access the drainage facilities. The access road would be paved and would be 20 feet wide with 40-foot diameter turnarounds to allow for vehicular and maintenance equipment site ingress/egress and connect to the proposed Private Street. Ramps would be constructed from the access roads to the top of the earthen debris basins to allow for vehicle access.

Landscape and Fuel Modification Improvements
Retaining walls would be screened by shrubbery. Anticipated landscape trees include canyon live oak, black walnut, Brisbane box, hollyleaf cherry, and Chinese pistache. All on-site lots would be equipped with landscaping irrigation. A 6-foot masonry screen wall would be constructed on the eastern edge of the Tract Map, which would serve as aesthetic fencing but also as wildfire protection between the Project site and the adjacent residential uses to the east.

Areas adjacent to the proposed debris basins would be subject to minimal grading/grooming to remove loose surface materials and reduce loose debris from running off into the debris basin facilities, as required by the Item #8. Page 497

LACFCD. Upon completion of the Project, the affected slopes would be hydroseeded with native seeds to facilitate the reestablishment of vegetative cover.

Offsite Components
A subterranean water, sewer, and storm drain infrastructure are the only off-site features required for Project implementation. The trenching required for pipeline installation and connection to subterranean existing utility infrastructure would be within paved roadways/driveways. Storm drain improvements along Palm Drive would require trenching within the existing sidewalk. The sidewalk would be repaved once storm drain improvements are implemented, as a condition of approval for the Project.

Short-Term Construction Activities
The first phases of construction would consist of site preparation and grading. During grading, the total cut is anticipated to be approximately 93,000 cubic yards, and the total fill is anticipated to be approximately 96,500 cubic yards, with 2,300 cubic yards of imported soils required. This includes 73,000 cubic yards of cut materials and 32,000 cubic yards of fill materials within the debris basin infrastructure hillside area, and 20,000 cubic yards of cut materials and 64,500 cubic yards of fill materials within the residential development area. Construction activities would occur in one phase, and could take place Monday to Friday from 7:00 a.m. to 6:00 p.m., with no work allowed on Saturdays, Sundays, or federal holidays, with the exception of interior work.

2 Regulatory Setting
This chapter outlines the federal, state, and local regulations pertinent to the biological resources located on the Project site.

2.1 Federal

2.1.1 Federal Endangered Species Act
The federal Endangered Species Act (FESA) of 1973 (16 USC 1531 et seq.), as amended, is administered by the U.S. Fish and Wildlife Service (USFWS) for most plant and animal species and by the National Oceanic and Atmospheric Administration National Marine Fisheries Service for certain marine species. This legislation is intended to provide a means to conserve the ecosystems upon which endangered and threatened species depend and provide programs for the conservation of those species, thus preventing the extinction of plants and wildlife.

The FESA defines an endangered species as “any species that is in danger of extinction throughout all or a significant portion of its range.” A threatened species is defined as “any species that is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range.” Under FESA, it is unlawful to “take” any listed species, and “take” is defined as, “harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or to attempt to engage in any such conduct.” FESA allows for the issuance of incidental take permits for listed species under Section 7, which is generally available for projects that also require other federal agency permits or other approvals, and under Section 10, which provides for the approval of habitat conservation plans on private property without any other federal agency involvement.

2.1.2 Migratory Bird Treaty Act
The Migratory Bird Treaty Act (16 USC 703 et seq.), as amended, prohibits the intentional take of any migratory bird or any part, nest, or eggs of any such bird. Under the Migratory Bird Treaty Act, “take” is defined as pursuing, hunting, shooting, capturing, collecting, or killing, or attempting to do so. Additionally, Executive Order 13186, Responsibilities of Federal Agencies to Protect Migratory Birds, requires that any project with federal involvement address impacts of federal actions on migratory birds with the purpose of promoting conservation of migratory bird populations (66 FR 3853–3856). The Executive Order requires federal agencies to work with USFWS to develop a memorandum of understanding. USFWS reviews actions that might affect these species.

2.1.3 Clean Water Act
The Clean Water Act provides guidance for the restoration and maintenance of the chemical, physical, and biological integrity of the nation’s waters. Section 401 requires a project operator for a federal license or permit that allows activities resulting in a discharge to waters of the United States to obtain state certification, thereby ensuring that the discharge will comply with provisions of the Clean Water Act. The Regional Water Quality Control Boards (RWQCB) administer the certification program in California. Section 402 establishes a permitting system for the discharge of any pollutant (except dredged or fill material) into waters of the United States. Section 404 establishes a permit program administered by USACE that regulates the discharge of dredged or fill material into waters of the Item #8. Page 500
Meeting Date: 1/24/2023 / Packet Page #: 565

GRAND ESTATES PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT 8375 6 MARCH 2022
United States, including wetlands. USACE implementing regulations are found at 33 CFR 320 and 330. Guidelines for implementation are referred to as the Section 404(b)(1) Guidelines, which were developed by the U.S.

Environmental Protection Agency in conjunction with USACE (40 CFR 230). The guidelines allow the discharge of dredged or fill material into the aquatic system only if there is no practicable alternative that would have less adverse impacts.

Wetlands and Other Waters of the United States
Aquatic resources, including riparian areas, wetlands, and certain aquatic vegetation communities, are considered sensitive biological resources and can fall under the jurisdiction of several regulatory agencies. USACE exerts jurisdiction over waters of the United States, including all waters that are subject to the ebb and flow of the tide; wetlands and other waters such as lakes, rivers, streams (including intermittent or ephemeral streams), mudflats, sandflats, sloughs, prairie potholes, vernal pools, wet meadows, playa lakes, or natural ponds; and tributaries of the above features.

The extent of waters of the United States is generally defined as that portion that falls within the limits of an ordinary high-water mark (OHWM). Typically, the OHWM corresponds to the water surface elevation of a 2-year flood event (USACE 2008a). In addition, waters of the United States may include wetlands, including swamps, bogs, seasonal wetlands, seeps, marshes, and similar areas, defined by USACE as “those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions” (33 CFR 328.3[b]; 40 CFR 230.3[t]). Indicators of three wetland parameters (i.e., hydric soils, hydrophytic vegetation, and wetlands hydrology), as determined by field investigation, must be present for a site to be classified as a wetland by USACE (USACE 1987).

2.2 State

2.2.1 California Endangered Species Act
The California Endangered Species Act (CESA) (California Fish and Game Code, Section 2050 et seq.) provides protection and prohibits the take of plant, fish, and wildlife species listed by the State of California. Unlike FESA, under CESA state-listed plants have the same degree of protection as wildlife, but insects and other invertebrates may not be listed. Take is defined similarly to FESA and is prohibited for both listed and candidate species. Take authorization may be obtained by the Project applicant from CDFW under CESA Section 2081, which allows take of a listed species for educational, scientific, or management purposes. In this case, private developers consult with CDFW to develop a set of measures and standards for managing the listed species, including full mitigation for impacts, funding of implementation, and monitoring of mitigation measures.

2.2.2 California Fish and Game Code
Fully Protected Species
Sections 3511, 4700, 5050, and 5515 of the California Fish and Game Code outline protection for fully protected species of mammals, birds, reptiles, amphibians, and fish. Species that are fully protected by these sections may not be taken or possessed at any time. CDFW cannot issue permits or licenses that authorize the “take” of any fully protected species, except under certain circumstances, such as scientific research and live capture and relocation Item #8. Page 501
Meeting Date: 1/24/2023 / Packet Page #: 566

GRAND ESTATES PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT 8375 7 MARCH 2022
of such species pursuant to a permit for the protection of livestock. Furthermore, it is the responsibility of the CDFW to maintain viable populations of all native species. Toward that end, the CDFW has designated certain vertebrate species as Species of Special Concern (SSC), because declining population levels, limited ranges, and/or continuing threats have made them vulnerable to extinction.

Section 1602
Under Section 1602 of the California Fish and Game Code, a Project operator is required to notify CDFW prior to any Project that would divert, obstruct, or change the natural flow, bed, channel, or bank of any river, stream, or lake. Pursuant to the code, a “stream” is defined as a body of water that flows at least periodically, or intermittently, through a bed or channel having banks and supporting fish or other aquatic life. Based on this definition, a watercourse with surface or subsurface flows that supports or has supported riparian vegetation is a stream and is subject to CDFW jurisdiction, with the jurisdictional limits extending beyond the top of bank to the outer canopy limits of riparian-associated vegetation that overlies the stream. Altered or artificial watercourses valuable to fish and wildlife are also subject to CDFW jurisdiction.

CDFW also has jurisdiction over dry washes that carry water during storm events.

Preliminary notification and Project review generally occur during the environmental process. When an existing fish or wildlife resource may be substantially adversely affected, CDFW is required to propose reasonable Project changes to protect the resource. These modifications are formalized in a Streambed Alteration Agreement, which becomes part of the plans, specifications, and bid documents for the Project.

California Native Plant Protection Act
The Native Plant Protection Act of 1977 (see Section 1900 et seq. of the California Fish and Game Code) directed CDFW to carry out the Legislature’s intent to “preserve, protect and enhance rare and endangered plants in this State.” The Native Plant Protection Act gave the California Fish and Game Commission the power to designate native plants as “endangered” or “rare” and protect endangered and rare plants from take. CESA expanded on the original Native Plant Protection Act and enhanced legal protection for plants, but the Native Plant Protection Act remains part of the California Fish and Game Code. To align with federal regulations, CESA created the categories of “threatened” and “endangered” species. It converted all “rare” animals into the act as threatened species, but did not do so for rare plants. Thus, there are three listing categories for plants in California: rare, threatened, and endangered. Because rare plants are not included in CESA, mitigation measures for impacts to rare plants are specified in a formal agreement between CDFW and the Project Applicant.

Nesting Birds
Section 3503 makes it unlawful to take, possess, or needlessly destroy the nest or eggs of any bird and Section 3513 makes it unlawful to take or possess any migratory nongame bird as designated in the MBTA.

2.2.3 California Environmental Quality Act
CEQA requires identification of a Project’s potentially significant impacts on biological resources and ways that such impacts can be avoided, minimized, or mitigated. The act also provides guidelines and thresholds for use by lead agencies for evaluating the significance of proposed impacts.

CEQA Guidelines Section 15380(b)(1) defines endangered animals or plants as species or subspecies whose “survival and reproduction in the wild are in immediate jeopardy from one or more causes, including loss of habitat, Item #8. Page 502
Meeting Date: 1/24/2023 / Packet Page #: 567

GRAND ESTATES PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT 8375 8 MARCH 2022
change in habitat, overexploitation, predation, competition, disease, or other factors.” A rare animal or plant is defined in Section 15380(b)(2) as a species that, although not presently threatened with extinction, exists “in such small numbers throughout all or a significant portion of its range that it may become endangered if its environment worsens; or … [t]he species is likely to become endangered within the foreseeable future throughout all or a significant portion of its range and may be considered ‘threatened’ as that term is used in the federal Endangered Species Act.” Additionally, an animal or plant may be presumed to be endangered, rare, or threatened if it meets the criteria for listing, as defined further in CEQA Guidelines Section 15380(c).

CDFW has developed a list of “Special Species” as “a general term that refers to all of the taxa the California Natural Diversity Database (CNDDB) is interested in tracking, regardless of their legal or protection status.” This is a broader list than those species that are protected under the FESA, CESA, and other California Fish and Game Code provisions, and includes lists developed by other organizations, including for example the Audubon Watch List Species. Guidance documents prepared by other agencies, including the Bureau of Land Management Sensitive Species and USFWS Birds of Special Concern, are also included on this CDFW Special Species list. Additionally, CDFW has concluded that plant species listed as California Rare Plant Rank (CRPR) 1 and 2 by the California Native Plant Society (CNPS 2022a), and potentially some CRPR 3 plants, are covered by CEQA Guidelines Section 15380.

Section IV, Appendix G (Environmental Checklist Form), of the CEQA Guidelines requires an evaluation of impacts to “any riparian habitat or other sensitive natural community identified in local or regional plans, policies, regulations, or by the California Department of Fish and Wildlife or the U.S. Fish and Wildlife Service.”

2.2.4 Porter–Cologne Water Quality Control Act
The intent of the Porter–Cologne Water Quality Control Act is to protect water quality and the beneficial uses of water, and it applies to both surface water and groundwater. Under this law, the State Water Resources Control Board develops statewide water quality plans, and the nine RWQCB develop basin plans that identify beneficial uses, water quality objectives, and implementation plans. The RWQCB have the primary responsibility to implement the provisions of both statewide and basin plans. Waters regulated under the Porter–Cologne Water Quality Control Act include isolated waters that are no longer regulated by USACE. Developments with impact to jurisdictional waters must demonstrate compliance with the goals of the act by developing stormwater pollution prevention plans, standard urban stormwater mitigation plans, and other measures to obtain an order of Waste Discharge Requirement (or, in cases where a CWA Section 401 certification is required, a waiver of Waste Discharge Requirement).

2.3 Local

2.3.1 City of Glendora General Plan
The following policies of the Land Use and Natural Resource Conservation Elements of the City of Glendora General Plan (2006) are relevant to naturally occurring biological resources:
▪ Goal CON-9: Preservation and conservation of natural resources and sensitive habitats. - CON-9.1 Investigate opportunities for open space land acquisition for the preservation of natural resources and sensitive habitats.

Item #8. Page 503
Meeting Date: 1/24/2023 / Packet Page #: 568

GRAND ESTATES PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT 8375 9 MARCH 2022
- CON-9.2 Continue to partner with the Glendora Community Conservancy to determine funding opportunities for open space land acquisitions for the preservation of natural resources and sensitive habitats. - CON-9.3 Pursue partnerships with other organizations, such as the United States Forest Service to ensure preservation of natural resources and sensitive habitats. - CON-9.4 Ensure the preservation of the natural plant communities in the hillside areas. - CON-9.5 Ensure land use decisions consider the preservation of sensitive plant and animal species, critical habitat, wildlife corridors, and biologically sensitive areas. - CON-9.6 Develop a land management/land maintenance plan, including best management practices, of City-owned conservation areas to increase fire safety, protect biodiversity and preserve native plant species.
- CON-9.7 Ensure preservation of local watersheds in development to maintain native plant habitats and ensure connectivity of wildlife corridors.
▪ Goal CON-10: A tree preservation strategy
o CON-10.1 Involve residents in the maintenance and preservation of individual trees by providing them with a choice of trees planted.
o CON-10.2 Maintain the tree preservation ordinance to ensure the preservation of existing tree resources. o CON-10.4 Ensure appropriate placement and proper maintenance of tree resources within the City.

The City of Glendora defines vegetation communities to be sensitive if they provide habitat for listed or otherwise sensitive species, are of special value to the local ecosystem (e.g., water sources), or are regulated by local, State or federal resources agencies (City of Glendora 2006a). Woodland habitats, particularly along streambeds, are recognized as being highly sensitive habitats because major drainages that contain woodland habitat support a wide diversity of wildlife species and may function as habitat linkages and corridors. Additionally, coastal sage scrub is considered a sensitive vegetation community based on extensive loss of habitat and widespread awareness among the resource agencies, policy makers, and public (City of Glendora 2006a). Woodland and coastal sage scrub habitats are considered special-status vegetation communities in this report based on their local importance as defined in the Glendora Community Plan (City of Glendora 2006a).

2.3.2 City of Glendora Tree Preservation Ordinance No. 1768 In accordance with Tree Preservation Ordinance No. 1768 (City of Glendora 2003), Section 20.08.130(6) requires that all existing living trees meeting the requirements in the Urban Forestry Manual (City of Glendora 2018aa), be preserved to the extent feasible as per recommendations provided by a certified arborist. If trees are destroyed, the applicant shall replace them with suitable trees in locations determined by the Planning Department before final occupancy is granted to any new resident. Additionally, where required by the Planning Department, the applicant shall submit a tree preservation/relocation/replacement/removal plan, which shall include the methods of tree preservation, tree replacement recommendations, and a report with recommendations from a certified arborist, as per the guidelines outlined in Tree Preservation Ordinance No. 1768 (City of Glendora 2003).

Item #8. Page 504
Meeting Date: 1/24/2023 / Packet Page #: 569

GRAND ESTATES PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT 8375 10 MARCH 2022
The Urban Forestry Manual defines policies and procedures utilized by City staff in the management and care of all trees located on City owned property, with City parkway areas, in some cases regarding California native species, and new developments (e.g., private property) (City of Glendora 2018a). The City takes impacts on private property trees into consideration with every application for discretionary zoning approval in order to maintain and further develop the local urban forest on public and private property within the City (City of Glendora 2018a). Removal of any species of private trees with a diameter at breast height (DBH) of 10 inches or more must be replaced according to the size scale described in the Urban Forestry Manual (City of Glendora 2018a).

Native oak trees are of particular importance within the City of Glendora. Any oak removed from private property with a DBH of 8” or more, as well as multi-trunk trees, oak or other species with a combined DBH of all trunk branches 4” DBH or greater shall require replacement as per the Urban Forestry Manual (City of Glendora 2018a), as shown in Table 1, City of Glendora Replacement Criteria for Privately Owned Trees. Additionally, the addendum to Chapter 16.12 of the City of Glendora tree preservation ordinance protects pre-existing or native trees that may be impacted by new development in the City (City of Glendora 2003, 2018). It is the City’s policy to protect and preserve healthy trees that provide valuable benefits to the environment and quality of life in Glendora (City of Glendora 2003, 2018).

3 Environmental Setting
The purpose of this chapter is to describe the general existing conditions within and adjacent to the Study Area to document the baseline conditions for the BRTR and subsequent analysis.

3.1 Climate
The Project site is located approximately 35 miles from the Pacific Ocean. The City of Glendora has a Mediterranean climate with cool, wet winters and hot, dry summers. August is the average warmest month with an average high temperature of 92 degrees Fahrenheit (˚F) and December is the coolest month on average with a low of 42 ˚F.

Rainfall occurs primarily between October and April, with the maximum average precipitation occurring in January.

According to the Western Regional Climate Center (WRCC) (2022), the mean annual rainfall for the region is 14.39 approximate inches of rain per year.

3.2 Soils
Soils mapping is from the County of Los Angeles, using the U.S. Department of Agriculture (USDA) National Resources Conservation Service (NRCS) Soil Survey Geographic database (County of Los Angeles 2014). Soils and their acreages are provided in Table 2, Soils on Grand Estates Site, spatial distributions are presented within Figure 3, Hydrogeologic Setting, and a brief description of each soil series is provided below.

Table 2. Soils on Grand Estates Site
Soil Mapping Unit Acres
Hanford Gravelly Sandy Loam 6.9
Upper San Gabriel River 20.0
Source: County of Los Angeles 2014.

Note: Numbers may not sum due to rounding.

Hanford gravelly sandy loam occurs within the southern portion of the Project area. This soil is well-drained and formed from moderately fine textured consolidated alluvium, soft shale, and fine grained sandstone. This soil is formed from alluvium dominantly from granite and other quarts rocks and occurs on floodplains, stream bottoms and alluvial fans.

The Hanford series are well-drained soils with low runoff and rapid permeability (USDA NRCS 2022a).

Upper San Gabriel River. Limited information is available for the upper San Gabriel river soils series. According to the Final Program Environmental Impact Report for the San Gabriel River Corridor Master Plan (County of Los Angeles 2006), the primary soils found within the upper San Gabriel river watershed consist of silt loam and sand.

3.3 Topography
On-site elevations range from 960 feet above mean sea level (AMSL) to 1,170 feet AMSL. The southern portion of the site, where development is proposed, is slightly south sloping and has a moderate to flat grade. Elevations across this portion of the site range from 960 to 1,025 AMSL. The northern approximately 16 acres, which are designated as preserve open space, contain moderate to steep slopes with elevations ranging from 1,026 feet to 1,170 feet AMSL.

GRAND ESTATES PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT 8375 12 MARCH 2022

3.4 Land Uses

3.4.1 On-Site Land Uses
The Project area is located along the foothills and hillsides of the San Gabriel Mountains. The Project area is largely undeveloped, with the exception of an existing single-family residential lot that is located along the southwestern portion of the Project site and zoned for development. The ground surface has been previously disturbed within the majority of the level areas zoned for single-family residential development and use. This area has been used as a Girl Scout camp and for various other outdoor uses. The northern portion of the Project area zoned as open space is comprised of moderate to steep slopes consisting of undeveloped canyons lined with coast live oak woodland and California walnut groves. Additionally, non-native grassland and disturbed California sagebrush scrub habitat occurs along the ridges of the mountains.

The Project is within the Low Density Residential Land Use Designation within the City of Glendora (City of Glendora 2018b). The Low Density Residential Designation is provided for transitional areas between hillside areas and higher density single-family residential areas and allows for the development of single family residential on lots ranging from 10,500 to 30,000 square feet (City of Glendora 2006b). The Project is within the Hillside Study Area and consistent with the Recommended Hillside Strategy document (City of Glendora 2006b). Based upon Dudek’s review of the General Plan, the Project would not conflict with any City goals, policies, and/or design.

3.4.2 Surrounding Land Uses
To the north of the Project site are mountainous, undeveloped areas within the northern portion of the City.

Approximately 0.31 mile to the north is the southern boundary of the Angeles National Forest. To the east of the Project site are hillside areas (also within the City of Glendora) that are sparsely developed with rural residences. (This area is designated as “Hillside Very Low Density” in the City’s General Plan.) The areas south and southwest of the Project site are developed with single-family residential neighborhoods. Approximately 0.15-mile southwest of the Project site is St. Lucy’s Priory High School. To the southwest of the Project site is also a small unincorporated area of the County, which is surrounded on all sides by the City of Glendora. This area is developed primarily with single-family residences. To the west of the Project site are single-family residences, undeveloped hillside areas within the City, and utility and flood control infrastructure, consisting of a concrete drainage system that leads out of the San Gabriel Mountains. Also to the west of the Project site is the Church of the Open Door, located approximately 0.15-mile west of the Project site.

Several County-designated Significant Ecological Areas (SEAs) are located near the Project site. The San Gabriel Canyon SEA is located approximately 0.35-mile northwest of the Project site. The East San Gabriel Valley SEA, which includes South Hills Park and surrounding undeveloped lands within the City, is located approximately two miles southeast of the Project site.

3.5 Watersheds and Hydrology
The Project site is located within the Upper San Gabriel Hydrologic Area of the San Gabriel River Unit (Figure 2, San Gabriel River Watershed). The Groundwater Basin Number is 4-13 (California Department of Water Resources 2016). The San Gabriel River is located approximately two miles west of the Project site and the Morris Reservoir is approximately 1.4 miles to the northwest. The river flows south coming out of the San Gabriel Mountains and Item #8. Page 507
Meeting Date: 1/24/2023 / Packet Page #: 572

GRAND ESTATES PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT 8375 13 MARCH 2022
then turns west as it makes its way to the Pacific Ocean (San Gabriel Watershed Master Plan 2006). Three main drainages are located within the Project site, which are currently intercepted by the three flood control/debris check dam structures. However, due to accumulated sediment and lack of maintenance, these structures are not functioning to retain debris or flood flows (Figure 2).

3.6 Fire History
The most recent fire (the Colby Fire) started on January 16, 2014 and occurred within the Project area. It burned approximately 1,952 acres, of which 15 acres burned within the Project site, including nearly all of the designated open space area. The fire destroyed five homes and damaged 17 structures in and around the Cities of Glendora and Azusa and the Angeles National Forest before it was contained on January 27, 2014 (CAL FIRE 2014). The Canyon Inn Fire was the last fire occurrence in the area prior to the Colby Fire and occurred 35 years prior on August 23, 1968.

4 Methods
Data regarding biological resources present on the Project site were obtained through a review of pertinent literature and through field reconnaissance; both of which are described in detail below. The approximate 27-acre property boundary is also referred to as the Study Area within this biological resources technical report.

4.1 Literature Review
Special-status biological resources present or potentially present in the Study Area were identified through a literature search using the following sources:
▪ CDFW CNDDB (CDFW 2022a) was queried to compile a list of potentially occurring flora and fauna in the Glendora, Azusa, and surrounding seven quadrangles
▪ CNPS Inventory of Rare, Threatened, and Endangered Plants of California, 8th online edition (CNPS 2022b), was searched to compose a list of potentially occurring flora in the Glendora, Azusa, and surrounding eight quadrangles
▪ Critical Habitat online viewer (USFWS 2022a)
▪ Wetland Mapper online viewer (USFWS 2022b)
▪ Watershed Assessment, Tracking and Environmental Results (WATERS) (EPA 2017) ▪ USGS National Hydrography Dataset (USGS 2022)
▪ Historic aerials and topographic maps (Google Maps 2022; NETR 2022; USGS 2018)

4.2 Resource Mapping
Biological fieldwork for the Project was originally conducted in May and July of 2014. Given the lapse in time from the initial surveys in 2014, an updated biological assessment was requested to determine whether biological resources on site have altered since the previous survey efforts were conducted. As such, an additional biological reconnaissance survey was conducted in April 2018 to update existing biological conditions within the Study Area.

The initial rare plant survey in 2014 was conducted during a significant drought that may have limited some species’ seeds from germinating and blooming. The above average rainfall in 2019 made conditions more amenable for blooming for the rare plant species that have been recorded in the Project vicinity. Additionally, the above average rainfall in the 2016-2017 and 2018-2019 rain seasons may have altered the drainage features that were mapped in 2014, so an update to the jurisdictional waters delineation was conducted. The 2014, 2018 and 2019 biological surveys included documenting vegetation communities and land covers present within the approximate 27-acre property boundary, including the approximate 11 acres zoned for single-family residences and 16 acres zoned for open space, delineation of jurisdictional wetlands or waters, and an evaluation of the potential for special-status plant and wildlife species to occur within the 27-acre property boundary. An additional survey was conducted in January 2022 to update the existing conditions since over two years had elapsed since the previous surveys.

4.2.1 Vegetation Community and Land Cover Mapping
Vegetation communities on the property were mapped using the List of Vegetation Alliances and Associations (Natural Communities List; CDFW 2022b), which is based on the Manual of California Vegetation, Second Edition (MCV2; Sawyer et al. 2009). As shown in Table 2, the vegetation mapping efforts were initially conducted in May 2014 by Dudek biologists Johanna Page and Britney Strittmater. The vegetation mapping was updated in April 2018 by Dudek biologists Johanna Page and Tracy Park to record any changes to vegetation communities since the 2014 surveys (Table 3). Dudek biologist Michael Cady updated the vegetation mapping in May 13, 2019, and confirmed existing conditions in January 21, 2022.

Vegetation communities were mapped in the field directly onto a 200-scale (1 inch = 200 feet) aerial map of the property. Community classifications were selected based on site factors, descriptions, distribution, and characteristic species present within an area. Information such as dominant species and their associated cover, Item #8. Page 511
Meeting Date: 1/24/2023 / Packet Page #: 576

GRAND ESTATES PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT 8375 17 MARCH 2022
aspect, and visible disturbance factors were recorded. To create the vegetation community map, Dudek Geographic Information Systems (GIS) technicians digitized the delineated vegetation boundaries from field maps using ArcGIS software. Holland (1986) was consulted as a resource for constituent plant species but was not used for mapping.

4.2.2 Flora and Fauna
All plant species encountered during the field surveys were identified and recorded. Latin and common names for plant species with a California Rare Plant Rank (formerly CNPS List) follow the California Native Plant Society OnLine Inventory of Rare, Threatened, and Endangered Plants of California (CNPS 2022b). For plant species without a California Rare Plant Rank, Latin names follow the Jepson Interchange List of Currently Accepted Names of Native and Naturalized Plants of California (Jepson Flora Project 2022), and common names follow the USDA NRCS PLANTS Database (USDA NRCS 2022b). A cumulative list of plant species observed on the Project site is presented in Appendix B.

Wildlife species detected during the initial field surveys by sight, calls, tracks, scat, or other signs were recorded.

Binoculars (10 x 42 magnifications) were used to aid in the identification of observed wildlife. In addition to species actually detected, expected wildlife use of the site was determined by known habitat preferences of local species and knowledge of their relative distributions in the area. Society for the Study of Amphibians and Reptiles (2017) for reptiles and amphibians, American Ornithologists Society (2019) for birds, Wilson and Reeder (2005) for mammals, and Moyle (2002) for fish. A list of wildlife species observed within the Project site is presented in Appendix C.

4.2.3 Focused Special-Status Plant Survey
Dudek Senior Biologist Michael Cady conducted focused surveys for rare and/or special-status plant species with a potential to occur within the Study Area in 2019. Two surveys were conducted, one in the spring and one in the summer, in order to cover the blooming period of the target species. Prior to the start of focused surveys, nearby reference populations were checked to verify that target species were in bloom.

The Study Area was surveyed with meandering transects searching for federally and/or state-listed plants known to occur or with the potential to occur within the Study Area. The surveys conformed to CNPS Botanical Survey Guidelines (CNPS 2001); Protocols for Surveying and Evaluating Impacts to Special Status Native Plant Populations and Natural Communities (CDFW 2018); and Guidelines for Conducting and Reporting Botanical Inventories for Federally Listed, Proposed, and Candidate Plants (USFWS 1996). All plant species encountered during the field surveys were identified to subspecies or variety, if applicable, to determine sensitivity status. Moreover, all plant species encountered in the field were recorded. If target species were encountered, data points were mapped in the field using a GPS unit.

4.2.4 California Gnatcatcher Protocol Surveys
The presence/absence focused survey for coastal California gnatcatcher (CAGN) (Polioptila californica californica) was conducted for the Project between May 15 and June 28, 2019. The survey was conducted within weather conditions and time frames appropriate for the detection of gnatcatchers. Weather conditions and survey dates are provided in Table 3. The survey routes focused on moderate to high quality habitat that dominates most of the study area. No portions of the survey routes encroached into USFWS designated critical habitat for the species.

Item #8. Page 512
Meeting Date: 1/24/2023 / Packet Page #: 577

GRAND ESTATES PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT 8375 18 MARCH 2022
The survey was conducted following the currently accepted protocol of the USFWS, Coastal California Gnatcatcher (Polioptila californica californica) Presence/Absence Survey Protocol (USFWS 1997). The Project site does not occur within an approved Natural Community Conservations Plan (NCCP) area, and therefore six surveys were conducted at a minimum of 7-day intervals during the breeding season (March 15 through June 30). In accordance with the protocol, no more than 80 acres of suitable habitat were surveyed by a single permitted biologist during each site visit conducted. Survey routes completely covered all areas of suitable CAGN habitat within the survey area and allowed for complete audible and visual coverage of all suitable CAGN habitat on site.

A 200-scale topographic map (1 inch = 200 feet) overlain with vegetation polygons and the survey area was utilized during the survey. Additionally, digital mobile maps were utilized during the surveys to assist in navigating each survey area. Appropriate binoculars (e.g., 8x42 through 10x50 magnification) were used to aid in detecting and identifying bird species. A recording of gnatcatcher vocalizations was played approximately every 50–100 feet to induce responses from potentially present gnatcatchers. Vocalization-playback would have been terminated immediately upon detection of any gnatcatchers to minimize the potential for harassment.

4.2.5 Jurisdictional Delineation
A formal (routine) jurisdictional delineation of features within the Study Area was first conducted by Dudek biologists Heather L. Moine and Johanna C. Page on July 22, 2014. The Study Area was surveyed on foot for waters of the United States, including wetlands, under the jurisdiction of the USACE, pursuant to Section 404 of the federal CWA, RWQCB, pursuant to the Section 401 of the CWA and Porter-Cologne Water Quality Control Act, and under the jurisdiction of the CDFW pursuant to Section 1602 of the California Fish and Game Code. Although an additional jurisdictional delineation was not conducted for the Project in 2018, jurisdictional features were assessed for further modifications and updated accordingly during the 2018 reconnaissance-level field survey.

A second formal (routine) jurisdictional delineation was conducted for the Study Area in 2019 following the above average rainfall in 2018-2019 rain season. The survey methodology also incorporated recent CDFW determinations on the limits that the agency takes jurisdiction over. The limits of the jurisdictional waters were checked for changes during the January 2022 site visit.

Non-wetland waters of the United States are delineated based on the presence of an OHWM as determined utilizing the methodology in A Field Guide to the Identification of the Ordinary High Water Mark (OHWM) in the Arid West Region of the Western United States, A Delineation Manual (USACE 2008a). Wetland waters of the United States are delineated based on methodology described in the 1987 Corps of Engineers Wetlands Delineation Manual (USACE 1987) and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Arid West Region (Version 2.0) (USACE 2008b). The USACE and U.S. Environmental Protection Agency (EPA) Rapanos Guidance states that the USACE will regulate: (i) traditional navigable waters of the United States and (ii) their adjacent wetlands as well as (iii) non-navigable tributaries to traditional navigable waters that are relatively permanent and (iv) wetlands that directly about such tributaries (USACE and EPA 2008). In addition, if a significant nexus has been determined, the USACE may also assert jurisdiction over (i) non-navigable tributaries that are not relatively permanent and (ii) their adjacent wetlands, as well as (iii) wetlands that are adjacent to but that do not directly about a relatively permanent non-navigable tributary (USACE and EPA 2008).

The CDFW jurisdiction is defined to the bank of the streams/channels or to the limit of the adjacent riparian vegetation.

For shallow drainages and washes that do not support riparian vegetation, the top of bank measurement may be the same as the OHWM measurement. Areas regulated by the RWQCB are generally concurrent with the USACE, but may include features isolated from navigable waters of the U.S. that have evidence of surface water inundation.

GRAND ESTATES PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT 8375 19 MARCH 2022
Features were delineated using a Trimble GeoXT handheld Global Positioning System (GPS) unit with submeter accuracy. Features were also documented directly onto a 200-scale field map (1 inch = 200 feet) with an aerial base. To assist in the determination of jurisdictional areas on site, data was collected at 59 locations (i.e., data stations). Hydrology, vegetation, and soils were assessed and data were collected and summarized. The location of data stations were collected using a Trimble GeoXT handheld GPS unit with sub-meter accuracy. Plant species were characterized as either obligate, facultative wetland, facultative, facultative upland, and/or upland per The National Wetland Plant List: 2016 Wetland Ratings (Lichvar 2016). Due to the absence of hydrophytic vegetation, soil pits were not excavated.

4.2.6 Survey Limitations
Special-status plant surveys were conducted in May and July of 2014, which resulted in detection and identification of most annual and perennial plant species that occur in the area. Additionally, all plants observed during the April 2018 vegetation mapping effort were recorded. The timing of the surveys coincided with the blooming periods for special-status plant species with a moderate to high potential to occur in the vicinity of the Project. Lower-than-average rainfall occurred in winter 2013 and 2014, which may have limited the number of plant individuals that germinated that year and limited the blooming period of those that did (WRCC 2014).

However, the above average rainfall that occurred in the winter of 2018 and 2019 provided conditions that were conducive for the detection of most plant species. A weather station at Big Dalton Dam has recorded 33.43 inches of precipitation since the beginning of the current rainy season (October 1, 2018), which is above the normal of 26.21 inches (LACDPW 2019).

Limitations of the surveys included a diurnal bias and the absence of trapping for small mammals, reptiles, and amphibians. The surveys were conducted during the daytime to maximize the detection of most animals. Birds represent the largest component of the vertebrate fauna, and because most birds are active in the daytime, diurnal surveys maximize the number of bird observations. Conversely, diurnal surveys usually result in few observations of mammals, many of which may only be active at night. In addition, many species of reptiles and amphibians are secretive in their habits and are difficult to observe using standard meandering transects. The purpose of the field surveys was to determine the likelihood of occurrence of any special-status plant or wildlife species based on the presence/absence of suitable habitat and other natural history elements that might predict their occurrence.

4.3 Special-Status Species Habitat Assessment
Endangered, rare, or threatened plant species as defined in Section 15380(b) of the CEQA Guidelines (14 CCR 15000 et seq.) are referred to as “special-status plant species” in this BRTR and include endangered or threatened plant species recognized in the context of CESA and FESA (CDFW 2019b) and plant species with a CRPR 1 through 4 (CNPS 2019b). Species with CRPR 3 or 4 may, but generally do not, qualify for protection under this provision.

Species with CRPR 3 and 4 are those that require more information to determine status and plants of limited distribution. Thus, only CRPR 3 and 4 plant species that were also locally recognized by the City of Glendora tree protection ordinance were analyzed further.

Endangered, rare, or threatened wildlife species as defined in CEQA Guidelines, Section 15380(b) (14 CCR 15000 et seq.), are referred to as “special-status wildlife species” and, as used in this report, include (1) endangered or threatened wildlife species recognized in the context of CESA and FESA (CDFW 2022c); (2) California Species of Item #8.

Special Concern as designated by CDFW (2022d); and (3) mammals and birds that are fully protected species as described in the California Fish and Game Code, Sections 4700 and 3511.

The CNDDB and CNPS database queries conducted during the literature review resulted in a list of plant and wildlife species that have recorded occurrences within the Project vicinity. For each species evaluated, a determination was made regarding the potential for the species to occur in the Study Area based on information gathered during the field reconnaissance, including the location of the site, habitats present, current site conditions, known range, habitat associations, preferred soil substrate, life form, elevation, and blooming period.

5.1.1 Coast Live Oak Woodland
Coast live oak woodland includes coast live oak as the dominant or co-dominant tree in the canopy. Coast live oak woodland has a continuous to open canopy less than 30 meters (98 feet) in height with a sparse to intermittent shrub canopy and sparse or grassy ground layer (Sawyer et al. 2009). Species associated with the coast live oak woodland alliance include bigleaf maple (Acer macrophyllum), blue oak (Quercus douglasii), box elder (Acer Item #8. Page 516
Meeting Date: 1/24/2023 / Packet Page #: 581

GRAND ESTATES PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT 8375 22 MARCH 2022
negundo), California bay (Umbellularia californica), Engelmann oak (Quercus engelmannii), California sycamore (Platanus racemosa), California black walnut (Juglans californica), valley oak (Quercus lobata), arroyo willow (Salix lasiolepis), California black oak (Quercus kelloggii), and madrone (Arbutus menziesii) (Sawyer et al. 2009).

The coast live oak woodlands within the Study Area are located within the northern portion of the property within areas designated as open space, and along the eastern and western perimeters of the property boundary where development is proposed to occur. The coast live oak woodlands within the northern portion of the property were previously burned during the 2014 Colby fire (discussed in Section 3.8); however, the community in this portion of the site seems to be recovering well. Coast live oak woodland occurring along the eastern and western boundaries of the property remained untouched by the fire.

This community is dominated by coast live oak, though California sycamore (Platanus racemosa), southern California black walnut, and Washington fan palm (Washingtonia robusta) are also scattered throughout this vegetation community. The understory within the coast live oak woodland mapped within the eastern perimeter of the Project site and within the areas zoned as Open Space - Natural (north of the Project site) include bromes (Bromus spp.), sowthistles (Sonchus spp.), ragweeds (Ambrosia spp.), Pacific poison oak, tree tobacco (Nicotiana glauca) annual yellow sweetclover (Melilotus indicus), Cucamonga manroot (Marah macrocarpa), Bermuda buttercup (Oxalis pes-caprae), Alefeld’s pea (Lathyrus vestitus var. alefeldii), narrowleaf bedstraw (Galium angustifolium), distant phacelia (Phacelia distans), and wild canterbury bells (Phacelia minor). The understory within the coast live oak woodland mapped within the western perimeter of the Study Area is associated with nonnative and landscaped species dominated by English ivy (Hedera helix), field bindweed (Convolvulus arvensis), tree tobacco, ornamental fig trees (Ficus sp.), and smilo grass (Stipa miliacea).

The coast live oak woodland alliance is ranked by the CDFW (2018) as a G5S4 alliance. This ranking indicates that globally the alliance is widespread, abundant, and is considered secure and within California the alliance is apparently secure (CDFW 2019b). Although this alliance is not considered a special-status vegetation community by CDFW (CDFW 2022b), woodlands are recognized as a special-status vegetation community by the City of Glendora (2006).

5.1.2 California Walnut Groves
California walnut groves include California black walnut as the dominant or co-dominant tree species in the canopy.

This community has a continuous to open canopy less than 15 meters (49 feet) in height with a sparse or grassy ground layer (Sawyer et al. 2009). Species associated with California walnut groves alliance include white alder (Alnus rhombifolia), California ash (Fraxinus dipetala), toyon (Heteromeles arbutifolia), coast live oak, valley oak, arroyo willow, red willow (Salix laevigata), blue elderberry (Sambucus nigra), and California bay (Sawyer et al. 2009).

California walnut groves on site were burned during the 2014 Colby fire as discussed in Section 3.6. Many of the California walnut trees burned during the fire were observed to be re-sprouting during the 2018 site visit. Several California walnut saplings are emergent throughout canyons and hills within the northern open space portion of the property. One community dominated by California walnut groves is located within the north-central portion of the Study Area, within the designated open space area. California walnut groves on site are dominated by California black walnut and contain a grassy understory comprised of various bromes (Bromus spp.) and wild oat (Avena spp.).

Other species present include coast live oak, California sycamore (Artemisia californica), Pacific poison oak (Toxicodendron diversilobum), white sage (Salvia apiana), and black mustard (Brassica nigra).

Item #8. Page 517
Meeting Date: 1/24/2023 / Packet Page #: 582

GRAND ESTATES PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT 8375 23 MARCH 2022
The California walnut grove alliance has a rank of G3S3 in CDFW (2018), meaning that it is vulnerable to extirpation or extinction both globally and within the state; and is therefore a special-status vegetation community and a high priority for inventory according to CDFW (2022b). Additionally, woodlands are recognized as a special-status vegetation community by the City of Glendora (2006).

5.1.3 Disturbed California Sagebrush Scrub
California sagebrush scrub is a community dominated or co-dominated by California sagebrush (Artemisia californica) with a continuous or intermittent shrub canopy less than two meters (seven feet) in height with a variable ground layer (Sawyer et al. 2009). This native plant community characterized by a variety of soft, low, aromatic, drought-deciduous shrubs, such as California sagebrush (Artemisia californica), coyote bush (Baccharis pilularis), Eastern Mojave buckwheat (Eriogonum fasciculatum), brittlebush (Encelia farinosa), chaparral yucca (Hesperoyucca whipplei), coastal pricklypear (Opuntia littoralis), and sages (Salvia spp.), with scattered evergreen shrubs, including lemonadeberry (Rhus integrifolia), laurel sumac (Malosma laurina), and toyon. It typically develops on steep, southfacing slopes and at times, though rarely, occurs on flooded low-gradient deposits along streams in which are scattered willows (Salix spp.) and mulefat (Baccharis salicifolia), depending on the site conditions.

This community was burned during the 2014 Colby fire, discussed further in Section 2.7. Within the Study Area, this community contains a high cover of non-native species including bromes, wild oat, castorbean (Ricinus communis), and black mustard as a result of the Colby fire. Emergent California sagebrush species including California sagebrush, laurel sumac, white sage, and common deerweed have become reestablished. Sprouting of coastal sage scrub habitats within inland areas is dependent almost entirely upon seed germination, whereas most sage scrub species re-sprout from below ground root crowns in coastal areas. Therefore, coastal sage scrub assemblages that regenerate primarily by seeding may be more vulnerable to the effects of non-natives compared with stands that regenerate by sprouting (O’Leary 1990a, 1990b). Essentially, it may take a number of years before this habitat type will reestablish, especially given the drought years preceding and following the 2014 Colby fire.

This community previously dominated hillsides throughout the northern open space portion of the Study Area; however, California sagebrush scrub is now limited approximately 1.6 acres, occurring as patches along extremely steep slopes.

California sagebrush scrub alliance has a rank of G5S5 (Faber-Langendoen et al. 2012), meaning it is globally secure and secure in the state. Although this alliance is not considered a special-status vegetation community by CDFW (2022b), coastal sage scrub habitats are recognized as a special-status vegetation community by the City of Glendora (2006).

5.1.4 California Annual (Non-Native) Grassland
California annual grassland (also referred to as non-native grassland in this report) is characterized by a mixture of weedy, introduced annuals, primarily grasses (Sawyer et al. 2009; Holland 1986). California annual grassland typically includes wild oats, bromes, black mustard, stork’s bill (Erodium spp.), dove weed (Croton setiger), Russian thistle (Salsola tragus), and Maltese star-thistle (Centaurea melitensis). It may occur where disturbance by maintenance (e.g., mowing, scraping, disking, and spraying), grazing, repetitive fire, agriculture, or other mechanical disruption has altered soils and removed native seed sources from areas formerly supporting native vegetation (Holland 1986).

Item #8. Page 518
Meeting Date: 1/24/2023 / Packet Page #: 583

GRAND ESTATES PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT 8375 24 MARCH 2022
California annual grassland is located throughout the central portion of the Study Area (within northern portion of where the Project development is proposed), as well as within the northern portion of the property within areas zoned as Open Space - Natural. This vegetation community is dominated by bromes (Bromus spp.), wild oat (Avena fatua), black mustard, castorbean, redstem stork’s bill (Erodium cicutarium), Cucamonga manroot (Marah macrocarpa), and dove weed (Croton setiger). Other native species found within the eastern portion of this grassland community include sugar sumac (Rhus ovata) and hollyleaf cherry (Prunus ilicifolia ssp. ilicifolia). This area appears to have been heavily altered by regular discing activities. Tree removal activities have also occurred in this area based on past aerial maps of the area. California annual grassland also dominates slopes and ridgelines throughout the northern portion of the Study Area, within the designated open space. Following the 2014 Colby fire (discussed in Section 3.6), California annual grassland has re-vegetated hillsides previously dominated by coastal sage scrub communities. A low cover of trees and shrubs remain emergent; however, these hillsides are dominated by bromes, as well as weedy, introduced annuals such as redstem stork’s bill, prickly Russian thistle, and shortpod mustard (Hirschfeldia incana). Other native species found scattered within this grassland community include laurel sumac, California sagebrush, brittlebush, and California four o’clock (Mirabilis laevis var. crassifolia).

The California annual (non-native) grassland alliance has a rank of G4S4 (Faber-Langendoen et al. 2012), meaning that it is apparently secure both globally and within the state, and is therefore not a special-status vegetation community according to CDFW (2019b). Additionally, California annual grassland is not recognized as a specialstatus vegetation community by the City of Glendora (City of Glendora 2006a).

5.1.5 Urban/Developed
Developed land refers to areas supporting by man-made structures including homes, yards, roadways, sidewalks, and other highly modified lands supporting structures associated with dwellings or other permanent structures.

Vegetation in these areas, if present at all, is typically associated with development landscaping. Within the Study Area, developed land is limited to the southwestern portion of the proposed development, consisting of an existing private resident and associated landscaping.

Developed land is not included in the Natural Communities List (CDFW 2022b). This community is not considered a special-status vegetation community by CDFW or the City of Glendora (City of Glendora 2006a).

5.1.6 Developed-Concrete Channel
Developed-concrete channel is characterized by barren or sparsely vegetated concrete-lined channels. On site, this land cover type is largely unvegetated and conveys run-off from adjacent hillside areas into a storm drain inlet near the intersection of Palm Drive and Grand Avenue immediately south of the project site. One concrete channel was mapped within the eastern portion of the property. The concrete channel on-site is ephemeral supporting little, if any, vegetation. The channel was approximately 4 to 5 feet wide along the channel bottom and between 3 and 4 feet tall.

Developed-concrete channel is not included in the Natural Communities List (CDFW 2022b). This community is not considered a special-status vegetation community by CDFW or the City of Glendora (City of Glendora 2006a).

5.1.7 Disturbed Land
Disturbed land includes areas that experience or have experienced high levels of human disturbance and as a result are generally lacking vegetation. Areas mapped as disturbed land may include unpaved roads, trails, and graded areas. Vegetation in these areas, if present at all, is usually sparse and dominated by non-native weedy herbaceous species. Within the study area, disturbed land includes dirt roads, and bare, open areas with less than 5% vegetative cover. Disturbed land is found throughout the proposed development area. Disturbed land is minimal within the areas designated for open space and includes a portion of a dirt road.

Disturbed land is not included in the Natural Communities List (CDFW 2022b). This community is not considered a special-status vegetation community by CDFW or the City of Glendora (City of Glendora 2006a).

5.1.8 Special-Status Vegetation Communities
During the vegetation mapping, three vegetation communities were mapped in the Study Area that are considered sensitive under CEQA by CDFW (2019b) and/or the City of Glendora (2006): California walnut groves, disturbed coastal sage scrub, and coast live oak woodlands.

Table 4 provides the acreage of each mapped vegetation community or land cover. Figure 4 shows the distribution of vegetation communities and land covers mapped within the Study Area.

A total of 129 plant species were recorded in the Study Area during 2014, 2018, 2019, and 2022 surveys, including 64 native species (50%) and 65 non-native species (50%). The cumulative list of plant species observed in the Study Area is provided in Appendix B.

5.3 Faunal Diversity
A total of 49 wildlife species were recorded in the Study Area during 2014, 2018, 2019, and 2022 surveys including 48 native species (98%) and one non-native species (2%). A full list of wildlife species observed in the Study Area is provided in Appendix C.

5.3.1 Amphibians and Reptiles
No amphibian species were observed during surveys; however, black-bellied slender salamander (Batrachoseps nigriventris) and garden slender salamander (Batrachoseps major major) have the potential to occur. Two reptile species have been observed within the Study Area, Great Basin fence lizard (Sceloporus occidentalis longipes) and California striped racer (Coluber lateralis lateralis). Additional species that are likely to occur within the Study Area include gopher snake (Pituophis catenifer annectens) and southern Pacific rattlesnake (Crotalus oreganus helleri).

5.3.2 Birds
Thirty-seven (37) bird species were observed or heard within the Study Area. Most bird species observed are common, disturbance-adapted species typical of urban and suburban settings such as house finch (Carpodacus Item #8. Page 520

GRAND ESTATES PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT 8375 26 MARCH 2022
mexicanus), mourning dove (Zenaida macroura), northern mockingbird (Mimus polyglottos), acorn woodpecker (Melanerpes formicivorus), and European starling (Sturnus vulgaris). One Cooper’s hawk (Accipiter cooperii) was observed within the coast live oak woodland habitat along the western perimeter of the property. A red-tailed hawk (Buteo jamaicensis) was audibly detected north of the property during the site visit conducted in July 2014 and visually detected soaring over the Project site during the site visit conduced in April 2018. A red-shouldered hawk (Buteo lineatus) was heard calling from the ornamental vegetation in the south of the Study Area in 2019.

5.3.3 Mammals
Four mammal species were detected in the Study Area during the surveys: coyote (Canis latrans), western gray squirrel (Sciurus griseus), California ground squirrel (Spermophilus [Otospermophilus] beecheyi), and mule deer (Odocoileus hemionus). Other common species that are likely to occur include common raccoon (Procyon lotor), striped skunk (Mephitis mephitis), and Virginia opossum (Didelphis virginica).

5.4 Special-Status Biological Resources

5.4.1 Special-Status Plant Species
No special-status plant species were documented in previous surveys of the Study Area. No special-status plants species were observed during Dudek’s 2014 and 2019 focused plant surveys, which were conducted during the blooming period and under conditions that would have allowed identification for species potentially present. Therefore, no special-status plant species were determined to have a moderate or high potential to occur in the Study Area.

Appendix D, Special-Status Plant Species with Recorded Occurrences in the Project Vicinity and Their Potential to Occur in the Study Area, lists the special-status plants with potential to occur at the Project site. Species that are either not expected to occur or have a low potential to occur are identified in Appendix D and are not analyzed further in this BRTR, with the exception of thread-leaved brodiaea (Brodiaea filifolia), since it is a federally and State-listed species with local records.

Thread-Leaved Brodiaea
Thread-leaved brodiaea is federally listed as threatened and State-listed as endangered. Critical habitat for the species has been designated approximately 1.4 miles east of the Study Area (USFWS 2022a). The species is a member of the brodiaea family (Themidaceae) and is a perennial bulbiferous herb. It produces several linear leaves from an underground corm, and blue to red-purple flowers on a leafless stalk. Thread-leaved brodiaea is usually found in herbaceous plant communities such as valley needlegrass grassland, valley sacaton grassland, nonnative grassland, alkali playa, southern interior basalt vernal pools, San Diego mesa hardpan vernal pools, and San Diego mesa claypan vernal pools in association with coastal sage scrub in some locations (USFWS 2009).

These herbaceous communities occur in open areas on clay soils, soil with clay subsurface, or clay lenses within loamy, silty loam, loamy sand, silty deposits with cobbles or alkaline soils. These soil and habitat conditions do not occur in the Study Area, so thread-leaved brodiaea is not expected to occur on site. Additionally, the reference population for the species along Colby Trail, approximately 1.5 miles to the east of the Study Area, was confirmed to be in bloom during the focused rare plant survey conducted in May 2019, and the species was not observed in the Study Area.

5.4.2 Special-Status Wildlife Species
One special-status wildlife species, yellow warbler (Setophaga petechia), was observed during the surveys in the Study Area. Three species has a moderate potential to occur in the Study Area: Southern California legless lizard (Anniella stebbinsi), coastal whiptail (Aspidoscelis tigris stejnegeri), and hoary bat (Lasiurus cinereus). Table 5, Special-Status Wildlife Species Present or with Moderate or High Potential to Occur within the Study Area, summarizes the species that occur or have a moderate or high potential to occur. Species that are either not expected to occur or have a low potential to occur are indicated in Appendix E, Special-Status Wildlife Species with Recorded Occurrences in the Project Vicinity and Their Potential to Occur in the Study Area, and are not analyzed further in this BRTR, with the exception of CAGN, since focused surveys were conducted for the species.

Coastal California Gnatcatcher
CAGN is a small songbird that is federally listed as threatened and a CDFW SSC species. This species is a year-round resident found below 2,500 feet in elevation within Southern California. This subspecies occurs from northwest Baja California, Mexico to Ventura County. The highest densities for CAGN occur in coastal areas of Orange and San Diego Counties (Mock 2004), with small, now disjunct populations documented for Ventura and Los Angeles Counties (Atwood et al. 1998). CAGN generally prefer open sage scrub habitats with California sagebrush as a dominant or codominant species. Nest placement is typically in areas with less than 40% slope gradient (Mock 2004).

Item #8. Page 523
Meeting Date: 1/24/2023 / Packet Page #: 588

GRAND ESTATES PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT 8375 29 MARCH 2022
No CAGN (i.e., individuals and/or nests) were detected within the Study Area during any of the surveys, including the protocol surveys conducted in 2019 (see Appendix F, 2019 Focused California Gnatcatcher Survey 45-Day Report for the Silent Ranch Hillside Subdivision Project, City of Glendora, California). Therefore, the Study Area is currently considered absent of the species. This species generally has a low potential to occur within the limited coastal scrub habitat in the Study Area. The burned coastal sagebrush scrub formerly dominating the northern portion of the Study Area is now mainly re-vegetated with non-native grasslands, with only remnant patches of coastal scrub present in the northeastern corner and central portion of the Study Area.

The closest documented occurrence of this species is 3.1 miles southeast of the Study Area, approximately 0.3- mile northeast of the intersection of E. Foothill Boulevard and S. Amelia Avenue, north of San Dimas Canyon, as shown in Figure 5, Coastal California Gnatcatcher. The potential for CAGN to occur within the Study Area prior to the burn is thought to be low based on the small, disjunct populations known to occur within Los Angeles and Ventura Counties (Atwood et al. 1998; Atwood and Bontrager 2001), the terrain within the Study Area is steeper than typically preferred by this species, and there is a poor connection to existing known populations.

Mountain Lion
Pursuant to the provisions of Section 2074.2 of the Fish and Game Code, the California Fish and Game Commission (“Commission”), at its April 15-16, 2020 meeting, accepted for consideration the petition submitted to list an evolutionarily significant unit (ESU) of mountain lion (Puma concolor) in southern and central coastal California as threatened or endangered under CESA. As such, the Southern California/Central Coast ESU mountain lion population is given the protection of a listed species until its listing is permanently confirmed or denied. The species requires large areas of relatively undisturbed habitats with adequate connectivity to allow for dispersal and gene flow. Mountain lion have large home ranges that include heterogenous habitats. In the United States these often consist of pine forests, riparian and oak woodlands, streams, chaparral, and grasslands, though they are also known to occur in desert habitats (Center for Biological Diversity and the Mountain Lion Foundation 2019). Nocturnal patterns of movement and stasis suggest that mountain lions generally avoid areas with human disturbance (i.e., residential developments and two-lane paved roads) and use a variety of habitats to stalk and pursue their prey (Center for Biological Diversity and the Mountain Lion Foundation 2019). Studies have shown that when traveling or hunting, the species preferred canyon bottoms and gentle slopes and used steeper slopes and ridgelines to a lesser extent (Center for Biological Diversity and the Mountain Lion Foundation 2019). Females keep their young in dens located in rocky terrain or in dense vegetation that provide cover, but avoid roads and stay at a distance from human disturbance four times greater (approximately 600 meters) than non-reproductive mountain lions (Center for Biological Diversity and the Mountain Lion Foundation 2019) Mountain lion are expected to use the study area for foraging, movement through its home range, or during the dispersal of young, with most movement occurring at night. Natal dens are not expected since the study area sustains a relatively high level of human activities due to the adjacent residential properties.

5.5 Critical Habitat
There is no USFWS-designated critical habitat within the Study Area. There is critical habitat for CAGN approximately 4.8 miles southeast of the Study Area, southwestern willow flycatcher (Empidonax traillii extimus) critical habitat is approximately 0.9 miles northwest of the Study Area., and thread-leaved brodiaea critical habitat is approximately 1.4 miles east of the Study Area (USFWS 2022a).

GRAND ESTATES PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT 8375 30 MARCH 2022

5.6 Wildlife Corridors and Habitat Linkages
Wildlife corridors are linear features that connect large patches of natural open space and provide avenues for dispersal or migration of animals and dispersal of plants (e.g., through wildlife vectors). Wildlife corridors contribute to population viability by assuring continual exchange of genes between populations, which helps maintain genetic diversity; providing access to adjacent habitat areas representing additional territory for foraging and mating; allowing for a greater carrying capacity; and providing routes for colonization of habitat lands following local population extinctions or habitat recovery from ecological catastrophes (i.e., the rescue effect).

Habitat linkages are small patches that join larger blocks of habitat and help reduce the adverse effects of habitat fragmentation. They serve as connections between habitat patches and help reduce the adverse effects of habitat fragmentation. Although individual animals may not move through a habitat linkage, the linkage is a potential route for gene flow and long-term dispersal. Habitat linkages may serve as both habitat and avenues of gene flow for small animals such as reptiles, amphibians, and rodents. Habitat linkages may be represented by continuous patches of habitat or by nearby habitat “islands” that function as steppingstones for dispersal and movement (especially for birds and flying insects). Wildlife corridors and habitat linkages provide avenues for dispersal or migration of animals that also contribute to population viability in several ways, including (1) ensuring continual exchange of genes between populations to aid in maintaining genetic diversity, (2) providing habitat for some species, (3) providing access to adjacent habitat areas representing additional territory for foraging and mating, (4) allowing for a greater carrying capacity, and (5) providing routes for colonization of habitat lands following local population extinctions or habitat recovery from ecological catastrophes.

The Study Area does not reside within any designated wildlife corridors and/or habitat linkages identified in the South Coast Missing Linkages analysis project (South Coast Wildlands 2008) or California Essential Habitat Connectivity project (Spencer et al. 2010). Although the Study Area is not located within a designated wildlife corridor or habitat linkage, the northern portion of the property contains drainage and oak woodland habitat that likely facilitates local wildlife movement. Mule deer were observed on the property during the field surveys, and are likely to use the hillsides, drainages and canyons on-site for wildlife movement. The site is also likely to support local movement of more common urban adapted species including coyote, striped skunk, and raccoon. On occasion, the canyons and drainages within the northern portion of the property may also facilitate movement for American black bear (Ursus americanus) and bobcat (Lynx rufus). However, the southern portion of the Project site and areas south and west of the Project site are dominated by residential development; and thus, is less likely to support wildlife movement. In summary, while there is potential for local wildlife movement to occur along the streambeds, canyons, ridgelines and hillsides within the northern portion of the Study Area, there is less suitable habitat for wildlife movement along the southern portion of the property where the majority of Project development is proposed.

5.7 Jurisdictional Delineation
With respect to USACE-jurisdictional waters of the U.S., including wetlands, the USACE makes the jurisdictional determination. The USACE issues two types of jurisdictional determinations—preliminary and approved.1 Both 1 The USACE issues two types of JDs—preliminary and approved. A preliminary JD is an expedited process typically initiated at the time that a 404 permit is requested for impacts to federal jurisdictional waters; the preliminary JD is non-binding and does not involve USACE review. This process is used when the permittee does not wish to request a determination that some or all of the potentially jurisdictional waters on the Project site are isolated (under the Rapanos decision) or otherwise not subject to federal jurisdiction. An approved JD is requested through submittal of a JD report and the accompanying form. It requires USACE review of the report and application of the criteria used to request a non-federal JD.

Item #8. Page 525
Meeting Date: 1/24/2023 / Packet Page #: 590

GRAND ESTATES PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT 8375 31 MARCH 2022
types of determinations require a submittal of a formal jurisdiction delineation report. CDFW and RWQCB also may request a site visit to review the jurisdictional delineation and may potentially change the limits of delineation. Therefore, the jurisdiction determinations provided in this technical report are preliminary and only identify the potential for jurisdictional areas to be affected by the Project in accordance with the CEQA thresholds.

There are three main drainages within the Study Area and several swale/erosional features. One of the drainages (Drainage E) flows into a concrete channel and is located in the southeastern portions of the site. Each channel segment has been labeled with a letter (A-E) and is shown on Figure 5, Potential Jurisdictional Waters. A total of 59 data stations were recorded. Detailed notes including the OHWM (if present), feature name, general area, feature notes, dominant plant species, hydrology notes, and photographs of the data stations and associated drainages for each data station are provided in Appendix G, Jurisdictional Delineation Data.

Each drainage is described in more detail in the remainder of this section.

Drainage A
Drainage A is ephemeral and flows northwest to southeast. Data stations 01-08 were collected for this feature.

Within the northern extent of Drainage A, a natural spring is present with surface water and a small amount of water flow. No hydrophytic vegetation was observed within the natural spring. Downstream of the natural spring, the OHWM is well defined with scouring, exposed roots, and drift deposits. Drainage A does not support hydrophytic vegetation in or adjacent to the channel.

Within the downstream portion of this feature is an approximately 20-foot tall concrete weir filled with rocks and mesh wiring. A USFS placard on the weir notes “1970 Los Angeles Flood Control District”. The function at this structure is to reduce the erosion of the stream bed thus conserving soil and water and encouraging plant growth.

It was constructed in cooperation with the United States Forest Service. For your safety please stay off." The OHWM end just downstream of the weir, making Drainage A an isolated feature.

Due to the absence of hydric soils and hydrophytic vegetation, there are no wetlands present within Drainage A.

However, Drainage A exhibits evidence of surface flow and the OHWM varies between 2-26 feet with OHWM indicators consisting of absence of vegetation, sediment deposition, and shelving. The feature is mostly vegetated with scattered shrubs, forbs, and non-native grasses, within an overstory canopy from coast live oak woodland.

Additional information recorded for Drainage A is provided in Appendix G.

Drainages B, C, and D
Drainages B, C and D are ephemeral drainages within the north-central portion of the site. Drainages B and C are tributaries to Drainage D. Drainage D generally flows north to the south. Data stations 09-25 were collected for these three features. All three drainages have steep slopes and lack hydrophytic vegetation within the OHWM or adjacent to the channel. The features are vegetated with a dense understory dominated by poison oak, edible fig, blue elderberry, and non-native grasses. The uppermost portions of Drainage C and D are within California walnut groves and the remainder is within coast live oak woodlands.

Due to the absence of hydric soils and hydrophytic vegetation, there are no wetlands present within Drainages B, C or D, but they do exhibit evidence of surface flow and the OHWM varies between 1-12 feet wide. OHWM indicators consist of absence of vegetation, sediment deposition, debris deposition, exposed roots, and shelving. However, Drainages B, C, and D are isolated features, with no observable connection to downstream waters.

Meeting Date: 1/24/2023 / Packet Page #: 591

GRAND ESTATES PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT 8375 32 MARCH 2022
Drainage E
Drainage E is ephemeral and flows north to south. The upstream portion is earthen-lined and flows into a concretelined trapezoidal channel. Data stations 42-51 were collected for the earthen-lined portion of this drainage. It is earthen-lined for approximately 7,193 linear feet and then flows are contained within a concrete-lined trapezoidal channel. Because the channel is concrete-lined, it lacks vegetation and there is no hydrophytic vegetation adjacent to the channel. No surface water was observed during the site visit. Data stations 52–57 were collected in the concrete-lined portion of Drainage E. The bottom of the concrete channel, measured as the OHWM, varies between 4 and 5 feet. The slopes of the concrete channel are between 3 and 4 feet tall.

The upstream earthen-lined portion of Drainage E is densely vegetated within a coast live oak woodland and understory dominated by black mustard, castorbean, greenspot nightshade (Solanum douglasii), and non-native grasses. The concrete channel has a disturbed California sagebrush scrub, non-native grasslands, and ornamental vegetation adjacent to the top of bank.

Due to the absence of hydric soils and hydrophytic vegetation in this portion of the channel, there are no wetlands present within Drainage E. However, the earthen-lined portion of Drainage E exhibits evidence of surface flow and the OHWM varies between 2 and 25 feet wide with OHWM indicators consisting of sediment deposition, debris deposition, exposed roots, and shelving. Drainage E flows into a storm drain inlet near the intersection of Palm Drive and Grand Avenue located immediately south of the Study Area site. It is assumed that this storm drain flows into the closest drainage, Little Dalton Wash (concrete channel), based upon the general topography of the region.

Little Dalton Wash is connected downstream to Big Dalton Wash, which is connected to the San Gabriel River.

Waters from the San Gabriel River flow into the Pacific Ocean.

5.7.1 Summary of Jurisdictional Delineation Results
Due to the absence of hydric soils and hydrophytic vegetation, there are no wetlands present within the Project site.

Evidence of flow and presence of an OHWM was documented in Drainages A–E; however, Drainages A-D are isolated linear features which are typically not waters of the U.S. but are waters of the State and CDFW jurisdictional resources.

Based upon the data gathered during the site visit, Drainages A–E may be under the jurisdiction of the USACE, RWQCB, and/or CDFW. Table 6, Potential Jurisdictional Waters within the Study Area, lists the acreage of the three potential jurisdictional waters types. It is anticipated that this BRTR would support the applications for a Section 404 Permit from the USACE, a Section 401 Water Quality Certification from the Los Angeles RWQCB, and a California Fish and Game Code Section 1602 Streambed Alteration Agreement from the CDFW.

5.8 Regional Resource Planning
The proposed Project does not occur within any adopted Habitat Conservation Plans (HCP), NCCP, or any other approved local, regional, or state conservation plans. Trees that are protected under the City Tree Preservation Ordinance No. 1768 are found in the Study Area.

5.8.1 City of Glendora Tree Preservation Ordinance No. 1768 A tree survey for the Project was completed in February 2014 (Bennett 2014) following the Colby Fire, which burned some of the trees in the open space portion of the Study Area. A second tree survey was conducted on August 15, 2018 (Bennett 2018). A large number of the trees including native oaks were damaged by the Colby Fire have succumbed to their injuries in the four and a half years since the fire. In August 2019, the trees surveyed in 2018 were checked to determine if any other mortality occurred. In August 2020, a third and final tree survey was performed.

The results of this survey are included as Appendix H, Tree Report (peer reviewed), along with the report issued in August 2019. The below discussion includes the results of the most recent (August 2020) tree survey.

A total of 835 trees were surveyed and mapped within the Study Area. Of these 835 trees, 639 are considered protected per the City of Glendora, and are listed in Table 7, Protected Trees in the Study Area. Four native trees species were identified: California black walnut, California sycamore, coast live oak, and toyon. An additional 24 nonnative or non-natural native species (native to California but planted for ornamental landscaping) were identified in the Study Area. Approximately 85 of the trees were assessed as having poor health (see Appendix H).

6 Project Impacts
This chapter addresses direct and indirect impacts to biological resources that would result from implementation of the proposed Project, along with the significance determinations for the proposed or potential impacts. Figure 7, Impacts to Biological Resources, illustrates the permanent and temporary impacts to biological resources in the Study Area.

6.1 Definition of Impacts
This section defines the types of impacts that would occur as are result of Project implementation, including direct permanent impacts, direct temporary impacts, and indirect impacts.

6.1.1 Direct Permanent Impacts
Direct permanent impacts refer to the absolute and permanent physical loss of a biological resource due to clearing and grading associated with implementation of the Project and are analyzed in four ways: (1) permanent loss of vegetation communities, land covers, and general wildlife and their habitat; (2) permanent loss of or harm to individuals of special-status plant and wildlife species; (3) permanent loss of suitable habitat for special-status species; and (4) permanent loss of wildlife movement and habitat connectivity in the Project area. Direct impacts associated with the proposed Project include the designed residential development and the footprint of proposed flood/debris control infrastructure (e.g., elevated storm drain inlets, debris basin, and access road).

6.1.2 Direct Temporary Impacts
Direct temporary impacts refer to a temporal loss of vegetation communities and land covers resulting from vegetation and land cover clearing and grading associated with construction of proposed temporary haul roads and construction of proposed permanent new access roads, slope remediation, grade control structures, installation of culverts, and other improvements required for the Project. The main criterion for direct temporary impacts is that impacts would occur for a short period of time and would be reversible. Areas temporarily disturbed by construction activities would be restored and revegetated with a native species mix similar to that which existed prior to disturbance following completion of work in the area such that full biological function can be restored. Direct temporary impacts associated with the proposed Project include temporary access, staging, and other work areas associated with installation of the flood/debris control infrastructure.

6.1.3 Indirect Impacts
Indirect impacts are reasonably foreseeable effects caused by Project implementation on remaining or adjacent biological resources outside the direct construction disturbance zone that may occur during construction (i.e., shortterm construction related indirect impacts) or later in time as a result of the development (i.e., long-term, or operational, indirect impacts). Indirect impacts may affect areas within the defined Project area but outside the construction disturbance zone, including open space and areas outside the Project area, such as downstream effects. Indirect impacts include short-term effects immediately related to construction activities and long-term or chronic effects related to the human occupation of developed areas (i.e., development-related long-term effects) and/or routine maintenance of infrastructure.

Item #8. Page 530
Meeting Date: 1/24/2023 / Packet Page #: 595

GRAND ESTATES PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT 8375 36 MARCH 2022
For the proposed Project, it is assumed that the potential short-term indirect impacts resulting from construction activities include dust, chemical pollution, noise, and general human presence that may temporarily disrupt species and habitat vitality, as well construction-related soil erosion and runoff that could affect downstream resources. With respect to potential downstream impacts, all Project grading will be subject to the typical restrictions and requirements that address erosion and runoff, including the federal CWA, National Pollution Discharge Elimination System (NPDES), and preparation of a Storm Water Pollution Prevention Plan (SWPPP).

The project would also result in long-term indirect impacts resulting from an increase in residential developed uses and routine maintenance of flood/debris control infrastructure. Such long-term indirect impacts include potential discharges of chemical pollutants, presence of non-native, invasive plant and animal species, increased human activity, construction equipment noise, and altered fire regime.

6.1.4 Explanation of Findings of Significance
Impacts to sensitive vegetation communities or riparian habitat, special-status plant species, special-status wildlife species, wildlife corridors and habitat connectivity, and regional resource planning must be analyzed to determine whether such impacts are significant. CEQA Guidelines Section 15064(b) states that an ironclad definition of “significant” effect is not possible because the significance of an activity may vary with the setting. However, CEQA Guidelines Section 15065(a) lists impacts that are helpful in defining whether a project may have a significant effect on the environment. Mandatory findings of significance, which require preparation of an EIR, occur when there is substantial evidence that a project could: (1) substantially degrade the quality of the environment, (2) substantially reduce the habitat of a fish or wildlife species, (3) cause a fish or wildlife population to drop below self-sustaining levels, (4) threaten to eliminate a plant or animal community, or (5) reduce the number or restrict the range of a rare or endangered plant or animal.

The following are the significance thresholds for biological resources provided in the CEQA Appendix G environmental checklist, which states that a project would potentially have a significant effect if it:
▪ Impact BIO-1. Would the project have a substantial adverse effect, either directly or through habitat modifications, on any species identified as being a candidate, sensitive, or special-status species in local or regional plans, policies, or regulations, or by CDFW or USFWS? ▪ Impact BIO-2. Would the project have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies, or regulations, or by CDFW or USFWS? ▪ Impact BIO-3. Would the project have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act (including but not limited to marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? ▪ Impact BIO-4. Would the project interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impedes the use of native wildlife nursery sites?
▪ Impact BIO-5. Would the project conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? ▪ Impact BIO-6. Would the project conflict with the provisions of an adopted habitat conservation plan, natural community conservation plan, or other approved local, regional, or state habitat conservation plan?

GRAND ESTATES PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT 8375 37 MARCH 2022
The evaluation of whether or not an impact to a particular biological resource is significant must consider both the resource itself and the role of that resource in a regional context. Substantial impacts are those that contribute to, or result in, permanent loss of an important resource, such as a population of a rare plant or animal. Impacts may be important locally because they result in an adverse alteration of existing site conditions but considered not significant because they do not contribute substantially to the permanent loss of that resource regionally. The severity of an impact and the offsetting benefits of mitigation are the primary determinants of whether or not that impact can be mitigated to a less-than-significant level.

6.2 Impacts to Special-Status Species
No special-status plant species were observed during the focused surveys and none have a medium or high potential to occur. Therefore, neither direct temporary or permanent impacts, nor indirect impacts, are expected and impacts would be less than significant. No mitigation is required.

6.2.1 Impacts to Special-Status Wildlife Species
Appendix E indicates the special-status wildlife species that were detected or have high or moderate potential to occur within the Study Area. Direct impacts to special-status wildlife species were quantified by comparing the limits of the proposed Project footprint with suitable habitat for these wildlife species and are further discussed below.

6.2.1.1 Direct Impacts
Special-Status Amphibians and Reptiles
No special-status amphibians or reptiles were detected during the 2014, 2018 and 2019 field surveys. Two specialstatus reptile species have moderate potential to occur in the Study Area: Southern California legless lizard and coastal whiptail. These species are both designated as CDFW SSC. Due to the presence of suitable habitat, and/or documented occurrences for these species within the vicinity of the Project site, there is potential for these species to occur on site. If these species are determined to occur on the Project site prior to construction, Project-related impacts could be considered significant if the impact causes the greater population of either species to drop below self-sustaining levels. These species are vulnerable to mortality or injury if struck by moving vehicles or equipment if present on-site during construction. These species are also vulnerable to mortality or injury during vegetation and ground disturbing activities associated with construction because they tend to be cryptic, slow moving, and below ground or under rocks or debris during cooler periods. No direct temporary impacts would occur; however, because habitat loss and/or mortality or injury to individual species is a reasonable possibility, direct permanent impacts would be considered potentially significant.

Project implementation of MM-BIO-1 would reduce potential direct impacts special-status wildlife (Southern California legless lizard and coastal whiptail) to a less-than-significant level through pre-construction surveys, avoidance, and potential relocation.

Special-Status Birds
One special-status bird species (yellow warbler) has a moderate potential to nest and forage within the open shrublands throughout the Project site. This species is a CDFW SSC and there is a potential for this species to nest and/or forage within or immediately adjacent to the proposed development footprint. If this species is determined Item #8. Page 532
Meeting Date: 1/24/2023 / Packet Page #: 597

GRAND ESTATES PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT 8375 38 MARCH 2022
to occur on the Project site prior to construction, Project-related direct impacts would occur particularly if construction would result in direct impacts to nesting and foraging habitat for yellow warbler.

Additionally, the trees and shrubs within the Project site provides suitable nesting habitat for bird species (i.e., yellow warbler and raptors) protected under the Migratory Bird Treaty Act (MBTA; 16 USC 703-712) and California Fish and Game Code Sections 3503.5, 3503, and 3513. Trimming, pruning, and/or removal of trees and shrubs may occur as a result of construction of the Project, and could disrupt breeding activity. There would be no direct temporary impacts; however, there may be a potential for a direct permanent impact to occur to nesting birds (i.e., direct impacts to individuals, active nests, eggs, or young), particularly during the general nesting season of February 1 through August 31. Construction activities that could result in direct impacts to nesting birds include vegetation and tree removal during grading activities. Project implementation of MM-BIO-2 (i.e., seasonal recommendations, pre-construction survey, avoidance buffers, and monitoring) would reduce potential direct impacts to a less-than-significant level.

Special-Status Mammals
No special-status mammals were detected during the 2014 and 2018 field surveys. No special- One special-status bat species (hoary bat) has a moderate potential for day/night roosting, maternity roosts, and foraging habitat within the Study Area. If this species is determined to occur on the Project site prior to construction, it is highly unlikely that short-term construction activities could cause the greater population of this special-status species to drop below self-sustaining levels due to the relatively small area of construction activity and the short-term nature of the construction schedule. No direct temporary impacts would occur; however, because habitat loss and/or mortality or injury to individual species is a reasonable possibility, direct permanent impacts would be considered potentially significant.

Project implementation of MM-BIO-3 (i.e., seasonal recommendations, pre-construction survey, avoidance buffers, and monitoring) would reduce potential direct impacts to a less-than-significant level. Direct impacts to day roosts occupied by individual special-status bat species would be less than significant as the impact would not be expected to reduce populations to below self-sustaining levels.

6.2.1.2 Indirect Impacts
Potential short-term indirect impacts to special-status wildlife could result from fugitive dust and increased human activity. Noise generated by construction activities, including vegetation removal and grading, that would be conducted during the avian breeding season (February 1 through August 31), could result in indirect impacts to nesting birds. Noise related to these activities has the potential to disrupt reproductive and feeding activities.

Nighttime construction is not expected for the Project, so indirect impacts on potentially foraging special-status bats is not expected. Potential temporary indirect impacts during construction may cause mortality due to the abandonment of an active nest and would be considered significant, absent mitigation. Project implementation of MM-BIO-2 would reduce these potential indirect impacts to a less-than-significant level. Long-term indirect impacts to special-status wildlife are not expected.

6.3 Impacts to Vegetation Communities and Land Covers

6.3.1 Direct Impacts
Direct permanent and temporary impacts to vegetation communities and land covers within the Study Area are summarized in Table 8, Permanent and Temporary Direct Impacts to Vegetation Communities and Land Covers, and illustrated on Figure 5, Impacts to Biological Resources, Direct impacts were quantified by calculating the Project impact area, which was delineated based on engineering plans that identified the limits of grading, within the boundaries of the vegetation communities mapped in the Study Area.

Notes:
* Special-status vegetation community per CDFW and/or the City of Glendora (2006). ** Total may not sum due to rounding.

Direct impacts to vegetation communities would occur as a result of earthwork and/or vegetation removal activities.

Direct permanent impacts would occur in the areas proposed for the development of graded pads and a private street in the southern section of the Project site, and for proposed flood/debris control improvements and access road in the northern section of the Project site. Direct temporary impacts to vegetation communities and land covers would occur only within the northern section of the Project site associated with the proposed flood/debris control improvements. As part of the proposed Project design, the affected areas would be hydroseeded with native seeds to facilitate the reestablishment of vegetative cover. Additionally, container trees and shrubs will be installed in the minimal grading/grooming areas per the Project’s approved landscaping plan.

The proposed Project would have 7.91 acres of direct permanent impacts to two sensitive vegetation communities (City of Glendora 2006a): coast live oak woodland and disturbed California sagebrush scrub. The Project would have 0.72 acres of direct temporary impacts to the two sensitive vegetation communities: California walnut woodland and disturbed California sagebrush scrub. Permanent and temporary direct impacts to coast live oak Item #8. Page 534
Meeting Date: 1/24/2023 / Packet Page #: 599

GRAND ESTATES PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT 8375 40 MARCH 2022
woodland, California walnut grove woodland, and disturbed California sagebrush scrub would be considered significant absent mitigation. Project implementation of MM-BIO-4 (i.e., preparation and implementation of a Habitat Restoration Plan) would reduce potential direct impacts to a less-than-significant level. Direct impacts to annual non-native grassland and non-natural land cover types are less than significant because these communities/land cover types are not considered sensitive by CDFW and/or the City of Glendora.

6.3.2 Indirect Impacts
Potential short-term indirect impacts to special-status vegetation communities in the Study Area would primarily result from construction activities and include impacts related to or resulting from the generation of fugitive dust, and increased human activity, the introduction of pollutants from construction equipment. Excessive dust can decrease the vigor and productivity of vegetation through effects on light, penetration, photosynthesis, respiration, transpiration, increased penetration of phytotoxic gaseous pollutants, and increased incidence of pests and diseases.

Erosion and chemical pollution (releases of fuel, oil, lubricants, paints, release agents, and other Project-related materials) may affect special-status vegetation communities. The use of chemical pollutants can decrease the number of plant pollinators, increase the existence of non-native plants, and cause damage to and destruction of native plants. These potential short-term, construction-related indirect impacts could affect the special-status vegetation communities in the Study Area.

Potential construction-related indirect impacts to special-status vegetation communities would be less than significant with the implementation of MM-BIO-5 (i.e., demarcation of disturbance limits and biological monitoring during vegetation removal).

Long-term indirect impacts to sensitive vegetation communities could result from Project implementation due activities associated with the residential development that includes chemical pollutants; non-native, invasive plant and animal species; increased human activity; and altered fire regime. Potential long-term indirect impacts to sensitive vegetation communities outside of the impact area would be significant absent mitigation. However, it is expected that the Project development will be subject to Glendora municipal codes and will have a homeowners association (HOA) that will be responsible for implementing Covenants, Conditions & Restrictions (CC&Rs) that must be reviewed by the City Attorney. It is expected that CC&Rs will contain restrictions on the use of chemicals that could pollute waters; ban the use of invasive species that are found on the California Invasive Plant Council’s (CalIPC) Inventory (Cal-IPC 2022); fencing between the development and preserved open space areas to limit human intrusion, and rules regarding fuel modification to limit the threat of fires. Therefore, long-term indirect impacts to sensitive vegetation communities would be less than significant based on compliance with regulations that would reduce the severity of potential indirect impacts such that sensitive vegetation communities would be expected to persist and have similar function to existing conditions, in areas adjacent to development.

6.4 Impacts to Jurisdictional Waters

6.4.1 Direct Impacts
The Project would result in both permanent and temporary direct impacts to jurisdictional waters during the construction the installation of the three debris basins (i.e., west, middle, and east basins) and the removal of the existing concrete channel, which occurs within the eastern portion of the property. The new debris basins and on site buried storm drain pipe system are proposed to be constructed to direct storm water flows south of the tract boundary where it will be released into the existing County Storm Drain system. Construction of the new buried Item #8. Page 535
Meeting Date: 1/24/2023 / Packet Page #: 600

GRAND ESTATES PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT 8375 41 MARCH 2022
storm drain system will eliminate the need for the concrete channel within the southern portion of Drainage E.

Temporary direct impacts will occur due to grading activities associated with the installation of the new debris basins. Table 9, Permanent and Temporary Direct Impacts to Potential Jurisdictional Waters, includes the acres of permanent and temporary impact, which are illustrated in Figure 7, Impacts to Biological Resources.

Notes:

There are no jurisdictional wetlands in the Study Area. The natural drainages and the concrete channel are potentially regulated by the USACE, RWQCB, and/or CDFW. The proposed Project would result in direct temporary and/or permanent impacts to these potentially jurisdictional waters, as summarized above. Direct impacts include discharge of fill (i.e., grading and construction/reconstruction of structures) to potentially jurisdictional waters, which would alter the size, scope, and character of these aquatic resources and therefore would be significant, absent mitigation.

Potential permanent and/or temporary impacts to jurisdictional waters be reduced to less than significant with the implementation of MM-BIO-5 and MM-BIO-6 (on-site restoration and/or land acquisition, mitigation program funding, and/or mitigation bank credits). Consultation with, and permit issuance from, USACE, RWQCB, and CDFW may result in higher mitigation ratios and specific criteria for restoration beyond the minimum standards presented in this mitigation.

6.4.2 Indirect Impacts
Potential temporary indirect impacts to jurisdictional waters in the Study Area would primarily result from construction activities and would include impacts from the generation of fugitive dust and the introduction of chemical pollutants (including herbicides). Excessive dust can decrease the vigor and productivity of vegetation through effects on light, penetration, photosynthesis, respiration, transpiration, increased penetration of phytotoxic gaseous pollutants, and increased incidence of pests and diseases. Erosion and chemical pollution (releases of fuel, oil, lubricants, paints, release agents, and other construction materials) may affect wetlands/jurisdictional waters.

The release of chemical pollutants can reduce the water quality downstream and degrade adjacent habitats.

However, during construction, erosion-control measures would be implemented as part of the Storm Water Pollution Prevention Plan (SWPPP) for the Project. Prior to the start of construction activities, the Contractor is required to file a Permit Registration Document (PRD) with the State Water Resources Control Board (SWRCB) in order to obtain coverage under the National Pollutant Discharge Elimination System (NPDES) General Permit for Storm Water Discharges Associated with the Construction and Land Disturbance Activities (Order No 2009-009- DWQ, NPDES No. CAS000002) or the latest approved general permit. This permit is required for earthwork that Item #8. Page 536
Meeting Date: 1/24/2023 / Packet Page #: 601

GRAND ESTATES PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT 8375 42 MARCH 2022
result in the disturbance of one acre or more of total land area. The required SWPPP will mandate the implementation of best management practices (BMPs) to reduce or eliminate construction-related pollutants in the runoff, including sediment. Therefore, temporary indirect impacts would be less than significant based on compliance with regulations that would reduce the severity of potential short-term indirect impacts such that jurisdictional waters would be expected to persist and have similar function to existing conditions, in areas adjacent to development.

Long-term indirect impacts to jurisdictional waters could result from Project implementation due activities associated with the residential development that includes chemical pollutants; non-native, invasive plant and animal species; increased human activity; and altered fire regime. Potential long-term indirect impacts to jurisdictional waters outside of the impact area would be significant absent mitigation. However, it is expected that the Project development will be subject to Glendora municipal codes and will have an HOA that will be responsible for implementing CC&Rs that must be reviewed by the City Attorney. It is expected that CC&Rs will contain restrictions on the use of chemicals that could pollute waters; ban the use of invasive species that are found on the Cal-IPC Inventory (Cal-IPC 2019); fencing between the development and preserved open space areas to limit human intrusion, and rules regarding fuel modification to limit the threat of fires. Therefore, long-term indirect impacts to jurisdictional waters would be less than significant based on compliance with regulations that would reduce the severity of potential long-term indirect impacts such that jurisdictional waters would be expected to persist and have similar function to existing conditions, in areas adjacent to development.

6.5 Impacts to Wildlife Corridors and Habitat Connectivity The Project site does not occur within any designated wildlife corridors or habitat linkages (South Coast Wildlands 2008, Spencer et al. 2010). The canyons and drainages within the designated open space areas in the northern portion of the property may facilitate local north-south wildlife movement through the area; however, the features do not provide a connection to other large open space areas to the south that may be used by wildlife. Therefore, neither direct temporary or permanent impacts, nor indirect impacts, are expected and impacts would be less than significant. No mitigation is required.

6.6 Regional Resource Planning
The Study Area does not occur within any proposed or approved HCP or NCCP (CDFW 2019c) and is outside the Angeles National Forest boundaries (USGS 2018). Trees that are protected under the City Tree Preservation Ordinance No. 1768 would be directly and indirectly impacted due to the construction of the Project.

6.6.1 Direct Impacts
It is anticipated that 455 protected trees would be removed as part of Project construction. These direct permanent impacts would be significant and there would be no temporary impacts. Project implementation of MM-BIO-7 (i.e., tree replacement) would reduce potential direct impacts to a less-than-significant level.

6.6.2 Indirect Impacts
Indirect impacts to trees are the result of changes to the site that may cause tree decline, even when the tree is not directly injured. Site-wide changes affecting trees include diverting runoff and stormwater, creating retention Item #8. Page 537
Meeting Date: 1/24/2023 / Packet Page #: 602

GRAND ESTATES PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT 8375 43 MARCH 2022
and detention ponds, relocating streams or making improvements to streams, lowering or raising water tables, altering the capacity for soil moisture recharge, removing vegetation, or damming underground water flow (Matheny and Clark 1998). Indirect tree impacts may potentially occur to trees that are within 25 feet of the proposed Project’s limits of grading.

Indirect impacts could potentially result in tree mortality adjacent to the Project work areas, which would be significant, absent mitigation, under the City’s Tree Ordinance. Project implementation of MM-BIO-8 (i.e., tree protection and monitoring) would reduce potential indirect impacts to a less-than-significant level.

7 Mitigation
The following mitigation measures shall be implemented during the proposed Project to reduce the significant impacts identified in Chapter 6 to a less-than-significant level.

7.1 Impact BIO-1: Special-Status Species
Significant direct and indirect impacts to special-status species can be mitigated to less than significant with implementation of the following measures:

MM-BIO-1 Special-Status Wildlife Relocation Plan. The applicant shall contract with a qualified biologist, whom shall be selected subject to the City’s approval, to prepare a Relocation Plan for Terrestrial Reptiles (Southern California legless lizard and coastal whiptail). The Plan shall at minimum include: identification of potentially occupied habitat, the timing and locations where surveys should be conducted; the habitat and conditions in the proposed relocation site(s); the methods that would be used for trapping and relocating the individual species; and requirements to provide the documentation/recordation of the species and number of animals relocated. The Plan shall be submitted to CDFW for review and must be approved by CDFW prior to commencement of any vegetation clearing or earthwork activities on the Project site.

Pre-Construction Surveys. Prior commencement of any vegetation clearing or earthwork activities on the Project site, a qualified biologist shall conduct a preconstruction survey within areas of suitable habitat identified in the Relocation Plan for Terrestrial Reptiles for specialstatus species wildlife (Southern California legless lizard and coastal whiptail). The biologist shall look for special-status species that may be located within or immediately adjacent to (within 100 feet) of the Project work areas, as permitted by access. Any individual specialstatus wildlife species observed within the Project work areas during the pre-construction survey shall be flushed and moved out of harm’s way to avoid direct impacts to these species (with special-status reptiles documented and relocated as per the approved Relocation Plan).

Monitoring. A qualified biologist shall be present during initial ground-disturbing activities within the Project site. The qualified biologist shall possess an appropriate California scientific collecting permit to handle special-status species likely to occur in the Project area. If specialstatus species reptiles are detected in the work area during the surveys, the authorized biologist will capture and relocate individuals to nearby undisturbed areas with suitable habitat outside of the construction area, but as close to their origin as possible (consistent with the approved Relocation Plan). All wildlife moved or flushed during Project activities shall be documented by the biologist and CDFW shall be notified.

MM-BIO-2 Direct and Indirect Impacts to Special-Status and Nesting Birds.

Nesting Bird Avoidance. Initiation of construction activities, including initial vegetation clearing, should avoid the migratory bird nesting season (February 1 through August 31) in order to avoid any potential significant impact to birds that may be nesting on the Project site. If construction activities must be initiated during the migratory bird-nesting season, an avian nesting survey Item #8. Page 540
Meeting Date: 1/24/2023 / Packet Page #: 605

GRAND ESTATES PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT 8375 46 MARCH 2022
of the Project site and contiguous habitat within 500 feet of all Project-related impact areas shall be conducted for protected migratory birds and active nests. The avian nesting survey shall be performed by a qualified wildlife biologist, subject to the City’s approval, within 72 hours prior to the start of construction-related activity in accordance with the Migratory Bird Treaty Act (16 USC 703–712) and California Fish and Game Code Sections 3503, 3503.5, and 3513.

If an active bird nest is found, the nest shall be flagged and mapped on the construction plans along with an appropriate no disturbance buffer, which shall be determined by the qualified wildlife biologist based on the species’ sensitivity to disturbance (minimum of 50 feet for common, urban-adapted species, 300 feet for other passerine species, and 500 feet for raptors and special-status species). The “no disturbance buffer” area shall be demarcated in the field with flagging and stakes or construction fencing and shall be avoided until the nest is vacated and the juveniles have fledged. The qualified biologist shall have the authority to stop work on the Project site and shall serve as a construction monitor during those periods when construction activities will occur near active nest areas to ensure that no inadvertent impacts on these nests occur.

MM-BIO-3 Bat Roost Avoidance. Initiation of construction activities, including initial vegetation clearing, should avoid the maternity roosting season (March through August), in order to avoid any potential significant impact to bat maternity roosts. If construction activities must be initiated during the maternity roosting season, a roost survey must be conducted by a qualified biologist, subject to the City’s approval. The roost survey for roosting bats shall be conducted on the Project site, including all trees and structures within 300 feet of Project-related impact areas, and shall be conducted no less than 30 days prior to commencement of construction activities.

If maternity roosting is identified, those trees and/or occupied structures shall not be removed during the bat maternity roost season (March to August) and a minimum 300-foot buffer shall be established. The “no disturbance buffer” area shall be demarcated in the field with flagging and stakes and the roost shall be monitored by a qualified biologist until roost is vacated and juveniles have fledged.

7.2 Impact BIO-2: Sensitive Vegetation Communities
Significant direct and indirect impacts to sensitive vegetation communities can be mitigated to less than significant with implementation of the following measures:

MM BIO-4 Mitigation for direct impacts to sensitive upland vegetation communities shall be implemented through on-site creation/enhancement of remaining sensitive upland vegetation communities and/or off-site acquisition, program funding, and/or mitigation bank credits. Mitigation acreages shall be implemented as shown in Table 10, Mitigation for Direct Impacts to Sensitive Vegetation Communities.

Mitigation for sensitive vegetation communities associated with potential jurisdictional waters is identified in MM BIO-6. Areas of temporarily impacted sensitive vegetation communities on site shall be returned to similar conditions that existed prior to grading and/or ground-disturbing activities. Additional unimpacted areas in the Project site that support California annual non-native grassland may be enhanced to support existing sensitive native vegetation communities. The CRP shall include restoration of the following habitats:
▪ Upland Woodlands. Impacted areas of upland woodland (i.e., coast live oak woodland and California walnut grove woodland) shall be created/restored within and adjacent to the same on-site areas that the woodland currently existed prior to Project implementation, as well as other areas deemed to have appropriate soils and topography for successful establishment. Prior to vegetation removal activities, native acorns/nuts shall be collected. Understory areas shall be revegetated with a diversity of locally-collected seeds. Temporary irrigation shall be established and maintained, with irrigation suspensions in times of rainfall. Successful establishment of the woodland shall be determined only after removal of irrigation system and confirmed ability of the woodland to survive in the absence of irrigation. Mitigation for impacts to woodlands shall be implemented at a ratio of no less than 3:1 and shall be accomplished through a combination of on-site replacement and enhancement, onsite preservation, and off-site acquisition and/or mitigation bank credits. If feasible, woodlands would be created/restored at a minimum of 1:1 on-site, with the goal of increasing on-site restoration beyond 1:1.
▪ Sagebrush Scrub. Impacted areas of California sagebrush scrub shall be created within and adjacent to the same on-site areas that the scrub currently exist, as well as other areas deemed to have appropriate soils and topography for successful establishment.

Prior to grading activities, native and locally collected seeds shall be collected be planted onsite within the mitigation areas. Irrigation shall be provided, as necessary, to assure establishment of the scrub. Based upon the disturbed, low quality nature of Item #8. Page 542

the existing California sagebrush scrub on site, mitigation of scrub shall be implemented at a ratio of no less than 1:1 and shall be accomplished through a combination of on-site replacement and enhancement, on-site preservation, and offsite acquisition and/or mitigation bank credits.

The CRP shall include a monitoring schedule, minimum performance standard of success, estimated costs, and identification of responsible entities. At a minimum, the CRP shall require a one-time restoration effort followed by monitoring and invasive weed removal for a minimum of five (5) years following ground-disturbing activities to compensate the direct temporary impacts. The monitoring program shall ensure successful establishment of the mitigation land, and if establishment is not realized within five years, restoration activities and monitoring may continue until minimum ratios as outlined above are established. The CRP shall be submitted to the City for review and shall revised to the satisfaction of the City..

MM-BIO-5 Indirect Impacts to Sensitive Vegetation Communities Flagging Limits. To prevent inadvertent disturbance to sensitive vegetation communities, including jurisdictional waters, outside the limits of work, the construction limits shall be clearly demarcated (e.g., installation of flagging or temporary high visibility construction fence) prior to ground disturbance activities. All construction activities including equipment staging and maintenance shall be conducted within the marked disturbance limits.

Monitoring. A qualified biologist, subject to the City’s approval, shall be present during initial ground-disturbing activities within the Project site to ensure that Project activities stay within the demarcated limits.

7.3 Impact BIO-3: Jurisdictional Wetlands and Waters
Significant direct and indirect impacts to jurisdictional waters can be mitigated to less than significant with implementation of the following measures:

MM-BIO-6 Mitigation for direct impacts to jurisdictional waters shall be implemented through on-site enhancement of remaining jurisdictional waters and/or off-site acquisition, program funding, and/or mitigation bank credits. Mitigation ratios for each type of jurisdictional waters is shown in Table 11, Mitigation for Direct Impacts to Potential Jurisdictional Waters.

On-site Mitigation. Prior to the issuance of a grading permit or any earthwork on the Project site, the Project Applicant shall prepare a (Habitat Mitigation and Monitoring Plan) HMMP for on-site mitigation for temporary and permanent impacts to jurisdictional resources (including coast live oak woodlands associated with the drainages), which shall include habitat enhancement and creation activities. The HMMP shall at a minimum include a feasible implementation structure, salvage/seeding details, invasive species eradication methods, irrigation system and schedule, a monitoring schedule, performance standard of success, estimated costs, and identification of responsible entities. The HMMP shall include restoration of the following habitats associated with the potential CDFW jurisdictional limits:
• Riparian Coast Live Oak Woodland. Impacted areas of coast live oak woodland within the CDFW jurisdictional limits shall be created/restored within and adjacent to the same on-site areas that the woodland currently existed prior to Project implementation, as well as other areas deemed to have appropriate soils and topography for successful establishment. Prior to vegetation removal activities, native acorns/nuts shall be collected. Understory areas shall be revegetated with a diversity of locally collected seeds. Temporary irrigation shall be established and maintained, with irrigation suspensions in times of rainfall. Successful establishment of the woodland shall be determined only after removal of irrigation system and confirmed ability of the woodland to survive in the absence of irrigation. If feasible, woodlands would be created/restored at a minimum of 1:1 on-site, with the goal of increasing onsite restoration beyond 1:1.

At a minimum, the HMMP shall require a one-time restoration effort followed by monitoring and invasive weed removal for a minimum of five (5) years following ground-disturbing activities to compensate the direct temporary impacts. The monitoring program shall ensure successful establishment of the mitigation land, and if establishment is not realized within five years, restoration activities and monitoring may continue until minimum ratios as outlined above are established. On-site land shall be preserved in perpetuity through a deed restriction or conservation easement, and the HMMP shall identify an approach for funding assurance for the long-term management of the conserved land. The HMMP shall be submitted to CDFW, USACE, and RWQCB for review and comment, and revised to the satisfaction of the City and the three agencies for their approval.

Off-site Mitigation. If mitigation is implemented off-site, the Project Applicant shall work with the CDFW, USACE, and RWQCB to ensure the purchase of land acquisition, mitigation program funding, and/or mitigation bank credits are appropriate to offset permanent impacts.

Mitigation lands shall be comprised of similar or higher quality riparian woodland and preferably located in the vicinity of the site or watershed. Any off-site land acquisition shall be preserved in perpetuity through a deed restriction or conservation easement, and an HMMP shall be prepared that identifies an approach for funding assurance for the long-term management of the purchased land.

GRAND ESTATES PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT 8375 50 MARCH 2022

7.4 Impact BIO-4: Habitat Linkages and Wildlife Corridors The Project site does not function as a wildlife corridor or habitat linkage and does not occur within any designated wildlife corridors of habitat linkages. Direct or indirect impacts to wildlife corridors and habitat connectivity are not anticipated; and would therefore, be less than significant.

7.5 Impact BIO-5: City of Glendora Protected Trees
Significant direct and indirect impacts to City protected trees can be mitigated to less than significant with implementation of the following measures:

MM-BIO-7 On-site Mitigation. Mitigation for City protected trees shall consider and overlap with any onsite compensation for special-status vegetation communities (MM-BIO-4 and MM-BIO-5) and jurisdictional waters (MM-BIO-6). Prior to the issuance of a grading permit or any earthwork on the Project site, a qualified arborist shall conduct a tree survey to confirm previous tree inventory data points and finalize the tree count for the purposes of replacement and shall prepare a protected Tree Planting And Maintenance Plan. The Plan shall be developed by a qualified arborist or landscape architect, subject to the City’s approval, and it shall identify tree planting locations, planting stock requirements, planting techniques, maintenance standards, tree protection standards, tree survival criteria, monitoring protocols, and reporting standards.

Minimum tree replacement to removal ratios shall be no less than the following for each trees diameter at breast height (dbh) in accordance with the City’s 2018 Urban Forestry Manual:

Native 8”-15” dbh 2:1 replacement
Native 16”-36” dbh 3:1 replacement
Native 37”-48” dbh 5:1 replacement
Native 49”-60” dbh 6:1 replacement
Native 61” dbh and up 7:1 replacement
Other 10”-15” dbh 1:1 replacement
Other 16”-36” dbh 1:1 replacement
Other 37”-48” dbh 2:1 replacement
Other 49”-60” dbh 3:1 replacement
Other 61” dbh and up 5:1 replacement
The plan shall be approved by the City prior to implementation.

Offsite Mitigation. For protected trees that are not replaced on-site, an in-lieu fee for future tree replacement shall be collected and deposited into a tree replacement fund. The in-lieu fee is based on the City’s cost to replant and set by City resolution.

MM-BIO-8 During Construction. Prior to issuance of the Project’s grading permit, the Applicant shall coordinate with LACFCD to assess the feasibility of oak tree preservation within the minimal grading/grooming areas and determine whether select trees could be preserved in place while maintaining the health and safety requirements of the LACFCD debris/flood control facility functions. Trees identified as being feasibly preserved and trees within approximately 15 feet of proposed construction activity shall be temporarily fenced with chain link or other material Item #8. Page 545
Meeting Date: 1/24/2023 / Packet Page #: 610

GRAND ESTATES PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT 8375 51 MARCH 2022
satisfactory to City planning staff throughout grading and construction activities. The fencing shall be installed three feet outside of the dripline of each tree (or edge of canopy for cluster of trees), be four-foot-tall, and staked every six (6) feet. The fenced area shall be considered the tree protection zone (TPZ) unless proximate construction required temporary removal. An International Society of Arboriculture Certified arborist shall monitor any construction activity taking place within or near to the TPZ and shall submit a Construction Observation letter to the City for approval, prior to final inspection, summarizing the results of the monitoring activity and resulting health of trees designated for preservation on-site.

Post-Construction. For a period of no less than five (5) years from the date of final inspection, an International Society of Arboriculture Certified arborist shall submit to the City a monitoring report annually. The report shall show compliance with the tree protection conditions of approval and verification that all trees are in good health. Further, all trees that have been substantially root pruned (30% or more of their root zone) during construction within the TPZ shall be monitored by an International Society of Arboriculture Certified arborist for the first five years after construction completion. The arborist shall submit an annual report, photograph each tree and compare tree health and condition to the original, pre-construction baseline.

7.6 Level of Significance After Mitigation
Implementation of these mitigation measures will reduce potential impacts to biological resources to below a level of significance.

Two special-status reptiles (Southern California legless lizard and coastal whiptail) have occurred in the Study Area.

Construction activities associated with the proposed Project could cause direct mortality of these species. MM-BIO1 requires the development of a special-status wildlife relocation plan, pre-construction focused special-status wildlife surveys, and monitoring during initial ground-disturbing activities. Potential direct impacts to Southern California legless lizard and coastal whiptail would be less than significant with implementation of MM-BIO-1.

Construction activities associated with the proposed Project could result in a loss of suitable habitat or direct take of birds and are considered significant. MM-BIO-2 requires nesting bird surveys within 300 feet (500 feet for raptors) of the proposed impact areas and if active nests are found, the biologist shall establish buffers and/or implement monitoring to avoid impacting avian nesting success. Potential direct impacts to protected nesting birds would be less than significant with implementation of MM-BIO-2.

One special-status bat (hoary bat) has a moderate potential to occur in the Study Area. Construction activities associated with the proposed Project could cause direct mortality of these species. MM-BIO-3 requires seasonal avoidance, pre-construction roost survey, and roost monitoring. Potential direct impacts to hoary bat would be less than significant with implementation of MM-BIO-3.

Significant direct and indirect temporary and permanent impacts to sensitive vegetation communities (coast live oak woodland alliance, California walnut woodland, and disturbed California sagebrush scrub) would occur due to implementation of the Project. MM-BIO-4 requires that habitat compensation be completed by the purchase of credits from an agency-approved mitigation bank or purchase of in lieu credits from an in-lieu fee program and/or through the preparation and implementation of on-site habitat restoration plan. MM-BIO-5 avoids indirect impacts to sensitive vegetation communities by requiring the demarcation of the disturbance limits. Impacts to sensitive vegetation communities and jurisdictional waters would be less than significant with implementation of MM-BIO-4 and MM-BIO-5.

Item #8. Page 546
Meeting Date: 1/24/2023 / Packet Page #: 611

GRAND ESTATES PROJECT / BIOLOGICAL RESOURCES TECHNICAL REPORT 8375 52 MARCH 2022
Significant direct and indirect temporary and permanent impacts to potential jurisdictional waters would occur due to implementation of the Project. MM-BIO-6 requires that jurisdictional waters compensation be completed by the purchase of credits from an agency-approved mitigation bank or purchase of in lieu credits from an in-lieu fee program and/or through the preparation and implementation of on-site habitat restoration plan. MM-BIO-5 avoids indirect impacts to jurisdictional waters by requiring the demarcation of the disturbance limits. Impacts to jurisdictional waters would be less than significant with implementation of MM-BIO-5 and MM-BIO-6.

Direct impacts would occur, and indirect impacts may occur, to trees protected by the City. MM-BIO-7 requires the replacement of the removed trees per a City-defined ratio and the development of a planting and maintenance plan that will guide the maintenance and monitoring of the replacement trees. MM-BIO-8 requires fencing to shield protected trees located in close proximity to construction activities and requires monitoring of any construction activities taking place within or near to the TPZ. MM-BIO-8 also requires annual tree surveys and submission of an annual tree monitoring report for a period of no less than five years, with additional requirements for trees that have sustained substantial root zone pruning. Impacts to protected trees would be less than significant with implementation of MM-BIO-7 and MM-BIO-8.

Subject: 2019 Focused California Gnatcatcher Survey 45-Day Report for the Silent Ranch Hillside Subdivision Project, City of Glendora, California
Dear Recovery Permit Coordinator:

This report documents the method and results of protocol-level presence/absence surveys conducted for the coastal California gnatcatcher (Polioptila californica californica; CAGN). Focused surveys were conducted throughout all areas of suitable habitat for the proposed Silent Ranch Hillside Subdivision Project located in the City of Glendora, Los Angeles County, California (Attachment A: Figure 1). Suitable habitat for CAGN is approximately

2.84 acres of coastal sage scrub vegetation (Disturbed California sagebrush scrub and disturbed deerweed scrub) within the study area (project site plus a 500-foot buffer). Dudek biologist Tommy Molioo (Authorized Individual under Brock Ortega, TE#813545-8.1) and Melissa Blundell (TE#97717A) conducted CAGN surveys from May through June 2019.

The CAGN is federally-listed as threatened and a California Department of Fish and Wildlife (CDFW) Species of Special Concern. It is closely associated with coastal sage scrub habitat and typically occurs below 950 feet elevation and on slopes less than 40% (Atwood 1990), but CAGN have also been observed at elevations greater than 2,000 feet. The species is primarily threatened by loss, degradation, and fragmentation of coastal sage scrub habitat, and is also impacted by brown-headed cowbird (Molothrus ater) nest parasitism (Braden et al. 1997).

LOCATION AND EXISTING CONDITIONS
The approximately 26.84-acre study area for the project is located within portions of an undeveloped hillside adjacent to an existing residential development in the City of Glendora, Los Angeles County, California (Attachment A: Figure 1). More specifically, the study area is physically located on privately owned land at 950 N. Silent Ranch Dr. The approximate centroid of the study area is at longitude -117.873400° West and latitude 34.152277° North within the U.S. Geological Survey (USGS) 7.5-minute Glendora and Azusa quadrangle maps, Township 10 North, Range 6 West, and Section 4 (USGS 1973). Elevations on site are approximately 1,000 feet to 1,100 feet above mean sea level.

VEGETATION COMMUNITIES
Six vegetation communities and land covers were identified within the study area, which are shown in Figure 2 and tabulated in Table 1. Suitable CAGN habitat within the study area includes disturbed California sagebrush scrub, which is described in detail below.

California Walnut Groves
California walnut groves include California black walnut (Juglans californica) as the dominant or co-dominant tree species in the canopy. This community has a continuous to open canopy less than 15 meters (49 feet) in height with a sparse or grassy ground layer (Sawyer et al. 2009). Species associated with California walnut groves alliance include white alder (Alnus rhombifolia), California ash (Fraxinus dipetala), toyon (Heteromeles arbutifolia), coast live oak (Quercus agrifolia), valley oak (Quercus lobata), arroyo willow (Salix lasiolepis), red willow (Salix laevigata), blue elderberry (Sambucus nigra ssp. caerulea), and California bay (Umbellularia californica) (Sawyer et al. 2009).

California walnut groves on site were burned during the 2014 Colby fire as discussed in Section 2.7. Many of the California walnut trees burned during the fire were observed to be re-sprouting during the 2018 site visit. Several California walnut saplings are emergent throughout canyons and hills within the northern open space portion of the property. One community dominated by California walnut groves is located within the north-central portion of the study area, within the designated open space area. California walnut groves on site are dominated by California black walnut and contain a grassy understory comprised of various bromes (Bromus spp.) and wild oat (Avena spp.).

Coast Live Oak Woodland
Coast live oak woodland includes coast live oak as the dominant or co-dominant tree in the canopy. Coast live oak woodland has a continuous to open canopy less than 30 meters (98 feet) in height with a sparse to intermittent shrub canopy and sparse or grassy ground layer (Sawyer et al. 2009). Species associated with the coast live oak woodland alliance include bigleaf maple (Acer macrophyllum), blue oak (Quercus douglasii), box elder (Acer negundo), California bay, Engelmann oak (Quercus engelmannii), California sycamore (Platanus racemosa), southern California black walnut, valley oak, arroyo willow, California black oak (Quercus kelloggii), and madrone (Arbutus menziesii) (Sawyer et al. 2009).

The coast live oak woodlands within the study area are located within the northern portion of the property within areas designated as open space, and along the eastern and western perimeters of the property boundary where development is proposed to occur. The coast live oak woodlands within the northern portion of the property were previously burned during the 2014 Colby fire; however, the community in this portion of the site seems to be recovering well. Coast live oak woodland occurring along the eastern and western boundaries of the property remained untouched by the fire.

This community is dominated by coast live oak, though California sycamore (Platanus racemosa), southern California black walnut, and Washington fan palm (Washingtonia robusta) are also scattered throughout this vegetation community. The understory within the coast live oak woodland mapped within the eastern perimeter of the project site and within the areas zoned as Open Space (north of the project site) include bromes, sowthistles (Sonchus spp.), ragweeds (Ambrosia spp.), Pacific poison oak, tree tobacco (Nicotiana glauca) annual yellow sweetclover (Melilotus indicus), Cucamonga manroot (Marah macrocarpa), Bermuda buttercup (Oxalis pes-caprae), Alefeld’s pea (Lathyrus vestitus var. alefeldii), narrowleaf bedstraw (Galium angustifolium), distant phacelia (Phacelia distans), and wild Canterbury bells (Phacelia minor). The understory within the coast live oak woodland mapped within the western perimeter of the project site is associated with non-native and landscaped species dominated by English ivy (Hedera helix), field bindweed (Convolvulus arvensis), Cucamonga manroot, tree tobacco, ornamental fig trees (Ficus sp.), and Stipa miliaceae.

Disturbed California Sagebrush Scrub
California sagebrush scrub is a community dominated or co-dominated by California sagebrush (Artemisia californica) with a continuous or intermittent shrub canopy less than two meters (seven feet) in height with a variable ground layer (Sawyer et al. 2009). This native plant community characterized by a variety of soft, low, aromatic, drought-deciduous shrubs, such as California sagebrush (Artemisia californica), coyote bush (Baccharis pilularis), Eastern Mojave buckwheat (Eriogonum fasciculatum), brittlebush (Encelia farinosa), chaparral yucca (Hesperoyucca whipplei), coastal prickly pear (Opuntia littoralis), and sages (Salvia spp.), with scattered evergreen shrubs, including lemonadeberry (Rhus integrifolia), laurel sumac (Malosma laurina), and toyon. It typically develops on steep, southfacing slopes and at times, though rarely, occurs on flooded low-gradient deposits along streams in which are scattered willows (Salix spp.) and mulefat (Baccharis salicifolia), depending on the site conditions.

This community was burned during the 2014 Colby fire. Within the project area, this community contains a high cover of non-native species including bromes, wild oat, castor bean (Ricinus communis), and black mustard as a result of the Colby fire. Emergent California sagebrush species including California sagebrush, laurel sumac, white sage, common deerweed have become reestablished. This community previously dominated hillsides throughout the northern open space portion of the study area; however, California sagebrush scrub is now limited as patches along in the eastern portion of the study area.

California Annual (Non-Native) Grassland
California annual grassland (also referred to as non-native grassland in this report) is characterized by a mixture of weedy, introduced annuals, primarily grasses (Sawyer et al. 2009; Holland 1986). California annual grassland typically includes oats, bromes (Bromus diandrus, B. madritensis, B. hordeaceus), black mustard, stork’s bill (Erodium spp.), dove weed (Croton setiger), prickly Russian thistle, and Maltese star-thistle (Centaurea melitensis). It may occur where disturbance by maintenance (e.g., mowing, scraping, disking, and Item #8. Page 616

spraying), grazing, repetitive fire, agriculture, or other mechanical disruption has altered soils and removed native seed sources from areas formerly supporting native vegetation (Holland 1986).

California annual grassland is located throughout the central portion of the study area (within northern portion of where the project development is proposed), as well as within the northern portion of the property within areas zoned as Open Space. This vegetation community is dominated by bromes (Bromus spp.), wild oat (Avena fatua), black mustard, castorbean, redstem stork’s bill (Erodium cicutarium), Cucamonga manroot, and dove weed (Croton setiger).

Other native species found within the eastern portion of this grassland community include sugar sumac (Rhus ovata) and hollyleaf cherry (Prunus ilicifolia ssp. ilicifolia). This area appears to have been heavily altered by regular discing activities. Tree removal activities have also occurred in this area based on past aerial maps of the area. California annual grassland also dominates slopes and ridgelines throughout the northern portion of the study area, within the designated open space. Following the 2014 Colby fire, California annual grassland has re-vegetated hillsides previously dominated by coastal sage scrub communities. A low cover of trees and shrubs remain emergent; however, these hillsides are dominated by bromes, as well as weedy, introduced annuals such as redstem stork’s bill, prickly Russian thistle, and shortpod mustard. Other native species found scattered within this grassland community include laurel sumac, California sagebrush, brittlebush, and California four o’clock (Mirabilis laevis var. crassifolia).

Ornamental
Ornamental plantings refer to areas where non-native ornamentals and landscaping have been installed.

Ornamental planting occur immediately north of West Palm Drive within the southern portion of the study area.

Ornamental species present include Peruvian peppertree, oleander (Nerium oleander), edible fig (Ficus carica), red ironbark (Eucalyptus sideroxylon), olive (Olea europaea), tree of heaven (Ailanthus altissima), Canary Island date palm (Phoenix canariensis), and ornamental pines. Planted natives observed within this land cover include coast live oak, southern California black walnut, and toyon.

Urban/Developed
Developed land refers to areas supporting by man-made structures including homes, yards, roadways, sidewalks, and other highly modified lands supporting structures associated with dwellings or other permanent structures.

Vegetation in these areas, if present at all, is typically associated with development landscaping. Within the study area, developed land is limited to the southwestern portion of the proposed development, consisting of an existing private resident and associated landscaping.

METHODS
The presence/absence focused survey for CAGN was conducted for the project between May 15 and June 28, 2019. The survey was conducted within weather conditions and time frames appropriate for the detection of gnatcatchers. Weather conditions and survey dates are provided below in Table 2. Survey routes are shown in Attachment A: Figure 2. The survey routes focused on moderate to high quality habitat that dominates the majority of the study area. No portions of the survey routes encroached into USFWS designated Critical Habitat for the species.

2 Survey Conditions: °F = degrees Fahrenheit; cc = cloud cover; mph = miles per hour The survey was conducted following the currently accepted protocol of the U.S. Fish and Wildlife Service (USFWS), Coastal California Gnatcatcher (Polioptila californica californica) Presence/Absence Survey Protocol (USFWS 1997). The project site does not occur within an approved NCCP area, and therefore six surveys were conducted at a minimum of 7-day intervals during the breeding season (March 15 through June 30). In accordance with the protocol, no more than 80 acres of suitable habitat were surveyed by a single permitted biologist during each site visit conducted. Survey routes completely covered all areas of suitable CAGN habitat within the survey area and allowed for complete audible and visual coverage of all suitable CAGN habitat on site.

RESULTS
No CAGN (i.e., individuals and/or nests) were detected within the project’s study area in 2019. Therefore, the study area is currently considered absent of CAGN. A full list of bird species observed during the survey and within proximity of the survey area is provided in Attachment B.

I certify that the information in this survey report and attached exhibits fully and accurately represent our work.

Sincerely,
Tommy Molioo

3 Site Location
Phase 1
The site is located at the north end of Grand Ave in the city of Glendora California.

Phase 2
This area is above the Glendora Heights project. The property line of the project runs in an EastWest direction along the base of the hill.

Site Conditions
Phase 1
The property was planted with many non-native trees as well as native oaks and sycamores. None of the trees appeared to have ever been pruned.

The Beefwood trees exhibited very poor structure and form with broken branch wounds throughout the canopies.

The majority of Canary Island Pines were planted in a large grouping. These trees have depended upon each other for support during wind events. Many of the oaks on the Northwest section of the property as well as the Pines and Eucalyptus trees were removed and used for firewood.

The Colby fire burned through the oak woodland in the northeast portion of the property damaging many of the trees. Fire crews removed trees on the perimeter during the fire.

The majority of the trees are showing signs of drought stress.

Phase 2
There ae three neglected debris basins constructed in the late 1960’s or early 1970’s to control the debris that has washed down in the past 48 years.

At the time of the construction of the debris basins care was not taken to prevent the loss of oak trees. As the basins filled up with sand and debris, the roots and trunks of the existing Oaks were covered and the grades were raised to the detriment of the trees. Many trees have died due to the grade changes.

Fire has had a devastating effect on the health of the trees. Without mans’ intervention most of the trees will slowly recover while many will succumb to their injuries. This will take many years to Item #8. Page 668

4 ascertain. Some trees were removed in early 2014 because they were not protected as they were non-native trees on private property.

I. Objectives
The objective of this report is to locate, record and evaluate all trees that will or may be impacted by the construction project. This information will assist the city staff in calculating the number of trees to be mitigated by tree replacement. Trees identified on a site map provided by the engineering firm.

The trees will be evaluated for health, disease, pests, structural defects, fire damage, and vigor.

The physical characteristics of the trees will be recorded including height, DBH and distance to the drip line (root protection zone).

II. Methods of Tree Analysis
I, Robert T Bennett, on August 15, 2019 performed a visual inspection and assessment of the trees. • All trees within the area that were delineated by the plans were tagged with metal 1 ¼ inch tags placed on the trunk in a conspicuous position so they can be spotted easily from a distance.
• The trees were measured with a diameter tape developed for this purpose. • The trees were evaluated for physical structure, species, disease, pests and health.

6 V. Results of Field Evaluation
Tree evaluation forms are provided with the report. The following information is in addition to tree evaluation forms:

1. Tree Numbers/Description of Health
VI. Summary of Field Evaluation
My original arborist report for this project was completed in February 2014. The Colby fire occurred during this time. Many trees were evaluated prior to the fire and others were evaluated after the fire.

A large number of the trees including the native oaks were damaged by the fire have succumbed to their injuries in the 41/2 years since the fire.

The report for this project was required by the City of Glendora Planning Department staff and since the tree ordinance had been updated, more trees were added to the report.

The total number of trees on this report is approximately 600.

This report is divided in 2 sections:

Section/Phase 1 contains 266 trees in the updated original report.

Section/Phase 2 contains 330 trees which is the added requirement to evaluate for the flood control area above the original project.

Revision added to Section/Phase 2 on August 24, 2019
As of August 24, 2019 I reviewed and updated the Preliminary Site Development plan submitted as requested. The plan included a larger area of grading higher up on the slopes than originally required due to the increased flood control requirements of the project.

When I completed my Tree Evaluations of the original Phase 2 area, I had already included all of the trees up the slope to the tree line. The tree line is the point where trees of a qualifying size (6 inches Item #8. Page 671
Meeting Date: 1/24/2023 / Packet Page #: 736
August 24, 2019
7 DBH) have stopped growing. Above this line the vegetation changes to small chaparral plants and grasses. Many of the trees documented in my original phase 2 report were outside of the area at that time, however they are now included per the revised map that was approved on April 4, 2019 by the City of Glendora which included a larger area for the Flood Control area as required by Los Angeles Flood Control District on this map.

2. Section/Phase 1 – Original Arborist in February 2014 The Canary Island Pines have grown depending upon each other for support during wind events.

These pines should not be left individually in a landscape because they may be subject to wind throw.

The Beefwood trees are all poor candidates to be retained in a new landscape. These trees have grown adjacent to the stand of Canary Pines and have benefited from the wind protection they provided. The tall thin trees may have branch failure during wind events if the stand of trees is thinned.

The Mexican Fan Palms are very tall and are unable to be relocated and supported. The Canary Palm would be good candidates for relocation.

The Colby fire will need time to recover to determine the extent of the damage to the individual trees in the woodland.

The trees on this property have been ravaged by neglect, drought, fire, and firewood collection.

During the Colby fire, firefighters fell dozens of trees intending to halt the advance of the fire by creating a fire break. Most of these trees were non-native species (Pine, Eucalyptus and Olives) and most of the felled wood was gathered and used for firewood. As noted on my tree evaluation forms, many trees have succumbed to the drought.

8 3. Section/Phase 2 – Updated Requirements
The second half of the report is focused on the hillside and debris basins to the north of the proposed housing project. This area above the project has had debris basins constructed in the late 1960’s and 1970’s to contain the debris after the devastating fires and floods. The basins are now full and no longer functional as designed.

The preliminary plans called for cleanout of the basins and grading and cleaning of the hillside surrounding the structures. In this report, trees numbered 270 through 600 are located, measured and evaluated in this area.

Many of the oaks are just now 4.5 years after the fire and are suffering catastrophic failure due to that fire that went through the property. Fire damage to trees takes years to manifest with native wood decay, pathogens and insects to degrade the structural integrity of the tree causing catastrophic failure of branches and trunks of trees. Dead trees in the bottom of the debris basin have died to the grade being raised around them along with drought and fire. The majority have failed at the soil level and all are decayed.

VIII. Recommendations
All of the non-native trees have grown for many, many years without proper pruning and care.

The Canary Pines have grown dependent on each other for support from the winds, for these reasons removing trees and leaving individual trees standing in a new landscape may create a condition where the remaining trees could fail in the case of a significant weather incident.

Creating hazardous conditions in a new landscape should be avoided at all costs.

Therefore I recommend that all of the non-native trees be removed.

The Canary Palms may be moved unless they can be incorporated into the new properties.

The majority of the trees in the Northeast corner of this phase have suffered catastrophic damage because of the fire. Now, after almost 5 years the effects of the fire are becoming evident. Total failure of main trunks is common as well as cavities forming and massive branch die-back.

9 Many of the trees throughout this project are in the same condition due to drought and fire damage.

The extreme poor health of the trees should be considered by the city when calculating tree replacement values.

A grading and construction plan for the rejuvenation of the three debris basins and the surrounding hillsides will be provided by Giron Engineering.
• IF all the trees in this planned area and debris basin restructuring are to be removed, here are the number of replacement trees per Glendora City Ordinance (page 21).

Executive Summary
Dudek was retained by City of Glendora Planning Department to prepare a historical significance evaluation report for an approximately 27-acre property located at 950 North Silent Ranch Drive in the City of Glendora, California (APN: 8684-045-004). The proposed project APE contains several buildings and structures over 45 years old that have not been previously evaluated for historical significance. This report includes a pedestrian survey of the property by a qualified architectural historian, a California Historical Resources Information System (CHRIS) records search of the APE and a 0.5-mile radius, building development and archival research, development of an appropriate historic context for the property, and evaluation of the property for historical significance and integrity in consideration of National Register of Historic Places (NRHP), California Register of Historical Resources (CRHR), and City of Glendora historic resources ad landmarks designation criteria. This report was prepared in conformance with California Environmental Quality Act (CEQA), and Section 106 of the National Historic Preservation Act (NHPA).

As a result of the CHRIS records search, extensive archival research with Glendora Historical Society, building permit history, field survey, and property significance evaluation, one historic property was identified within the APE: the Metropolitan Water District of Southern California (MWD) Upper Feeder pipeline and its associated concrete hatch structure. The MWD pipeline is recommended eligible under Criteria A/1/as a representative component of the MWD Upper Feeder pipeline, which was instrumental in delivery of Colorado River Water to the region, and the first multi-city municipal water distribution system of its kind. The period of significance for this historic property is 1931 to 1941. In consideration of these findings, the MWD pipeline and hatch structure are considered an historic property under Section 106 of the NHPA and an historical resource under CEQA. Impacts discussion, mitigation measures, and management recommendations are discussed in Section 6.

The remaining resources located at 950 North Silent Ranch Drive (APN: 8684-045-004): the Rancho Los Alisos Structures, Camp Aventura building, and joint Forest Service and County Flood Control District dams and channel do not appear not eligible for the NRHP, CRHR, or as a City of Glendora historic resource or landmark due to a lack of significant historical associations and architectural merit. Therefore, these resources are not considered historical resource for the purposes of CEQA. No management recommendations are required for these ineligible resources.

1 Introduction
Dudek was retained by City of Glendora Planning Department to complete a historical significance evaluation report for an approximately 27-acre property located at 950 North Silent Ranch Drive in the City of Glendora, California (APN: 8684-045-004) (hereafter, proposed project APE). The proposed project APE contains several buildings and structures over 45 years old and has not been previously evaluated for historical significance. This report includes a pedestrian survey of the property by a qualified architectural historian, a California Historical Resources Information System (CHRIS) records search of the APE and a 0.5-mile radius, building development and archival research, development of an appropriate historic context for the property, and evaluation of the property for historical significance and integrity in consideration of National Register of Historic Places (NRHP), California Register of Historical Resources (CRHR), and City of Glendora historic resources ad landmarks designation criteria.

This report was prepared in conformance with California Environmental Quality Act (CEQA) Guidelines Section 15064.5 for historical resources and Section 106 of the National Historic Preservation Act (NHPA) for historic properties.

1.1 Project Description and Location
The Grand Estates Project (proposed project) would involve the subdivision of a hillside property in the City of Glendora for the development of 13 single-family residential lots and one private street. It is expected that 12 singlefamily homes would be constructed on the new lots (one lot has an existing home, to remain in place). The proposed project area of potential effect (APE) is approximately 27 acres in size and is located at 950 North Silent Ranch Drive, at the northern terminus of Grand Avenue in the City of Glendora (Figure 1. Project Vicinity). The majority of the proposed project APE is currently vacant and undeveloped, with the exception of one single-family residence and three flood control structures, which are intended to control debris flow from the hillside above. The existing single-family residence would remain in place, and the three existing flood control structures would be demolished and new debris basins and maintenance road would be constructed as part of the proposed project, to provide effective protection from debris flow and flooding.

1.2 Area of Potential Effects (APE)
The APE is the geographic area or areas within which an undertaking may directly or indirectly cause changes in the character or use of historic properties. Delineation of the APE is influenced by the project’s setting, the scale and nature of the undertaking, and the different kinds of effects that may result from the undertaking (36 Code of Federal Regulations [CFR] 800.16[d]). Specifically, the APE follows the maximum possible area for potential impacts resulting from the proposed project, including all ground disturbing activities related to construction, easements, and staging areas located in the proposed project APE. Potential ground disturbance ranges from 25 to 35 feet deep with at least five feet of over-excavation to compensate for irregularities in the subgrade. Therefore, the vertical APE is up to 40 feet. The proposed project would affect the buildings and structures at 950 North Silent Ranch Drive, Glendora California. (Figure 2. APE Map).

1.3 Project Personnel
This report and associated property evaluation was prepared by Dudek Architectural Historian Kate Kaiser, MSHP.

The report was reviewed for quality assurance/quality control by Dudek Senior Architectural Historians Kathryn Haley, MA and Samantha Murray, MA. All authors and reviewers meet the Secretary of the Interior’s Professional Qualification Standards (36 CFR Part 61) for architectural history or archaeology (see Appendix A, Preparers’ Qualifications).

1.4 Regulatory Setting
National Historic Preservation Act
The NHPA established the NRHP and the President’s Advisory Council on Historic Preservation (ACHP), and provided that states may establish State Historic Preservation Officers (SHPOs) to carry out some of the functions of the NHPA. Most significantly for federal agencies responsible for managing cultural resources, Section 106 of the NHPA directs that “[t]he head of any Federal agency having direct or indirect jurisdiction over a proposed Federal or federally assisted undertaking in any State and the head of any Federal department or independent agency having authority to license any undertaking shall, prior to the approval of the expenditure of any Federal funds on the undertaking or prior to the issuance of any license, as the case may be, take into account the effect of the undertaking on any district, site, building, structure, or object that is included in or eligible for inclusion in the NRHP.” Section 106 also affords the ACHP a reasonable opportunity to comment on the undertaking (16 U.S. Code 470f).

The content of 36 Code of Federal Regulations, Part 800 (36 CFR 800) implements Section 106 of the NHPA. It defines the steps necessary to identify historic properties (those cultural resources listed in or eligible for listing in the NRHP), including consultation with federally recognized Native American tribes to identify resources with important cultural values; to determine whether or not they may be adversely affected by a proposed undertaking; and to outline the process for eliminating, reducing, or mitigating the adverse effects.

The ACHP provides methodological and conceptual guidance for identifying historic properties. In 36 CFR 800.4, the steps necessary for identifying historic properties are as follows:
• Determine and document the APE (36 CFR 800.16(d)).
• Review existing information on historic properties within the APE, including preliminary data. • Confer with consulting parties to obtain additional information on historic properties or concerns about effects to these.
• Consult with Native American tribes (36 CFR 800.3(f)) to obtain knowledge on resources that are identified with places where they attach cultural or religious significance. • Perform appropriate fieldwork (including phased identification and evaluation). • Apply NRHP criteria to determine resource eligibility for NRHP listing.

Fulfilling these steps is generally thought to constitute a reasonable effort to identify historic properties within the APE for an undertaking. The obligations of a federal agency must also assess whether an undertaking will have an adverse effect on cultural resources. An undertaking will have an adverse effect when:
an undertaking may alter, directly or indirectly, any of the characteristics of a historic property that qualify the property for inclusion in the National Register in a manner that would diminish the integrity of the property's location, design, setting, materials, workmanship, feeling, or association.

Consideration shall be given to all qualifying characteristics of a historic property, including those that may have been identified subsequent to the original evaluation of the property’s eligibility for the National Register. Adverse effects may include reasonably foreseeable effects caused by the undertaking that may occur later in time, be farther removed in distance or be cumulative” (36 CFR Part 800.5(1)).

The process of determining whether an undertaking may have an adverse effect requires the federal agency to confer with consulting parties to appropriately consider all relevant stakeholder concerns and values. Consultation regarding the treatment of a historic property may result in a Programmatic Agreement and/or Memorandum of Agreement between consulting parties that typically include the lead federal agency, SHPO, and other applicable parties if they agree to be signatories to these documents. Treatment documents—whether resource-specific or generalized—provide guidance for resolving potential or realized adverse effects to known historic properties or to those that may be discovered during implementation of an undertaking. In all cases, avoidance of adverse effects to historic properties is the preferred treatment measure, and it is generally the burden of the federal agency to demonstrate why avoidance may not be feasible.

Federal
National Register of Historic Places
The NRHP is the United States’ official list of districts, sites, buildings, structures, and objects worthy of preservation.

Overseen by the National Park Service, under the U.S. Department of the Interior, the NRHP was authorized under the National Historic Preservation Act, as amended. Its listings encompass all National Historic Landmarks, as well as historic areas administered by the National Park Service.

NRHP guidelines for the evaluation of historic significance were developed to be flexible and to recognize the accomplishments of all who have made significant contributions to the nation’s history and heritage. Its criteria are designed to guide state and local governments, federal agencies, and others in evaluating potential entries in the NRHP. For a property to be listed in or determined eligible for listing, it must be demonstrated to possess integrity and to meet at least one of the following criteria:

The quality of significance in American history, architecture, archaeology, engineering, and culture is present in districts, sites, buildings, structures, and objects that possess integrity of location, design, setting, materials, workmanship, feeling, and association, and:

A. That are associated with events that have made a significant contribution to the broad patterns of our history; or
B. That are associated with the lives of persons significant in our past; or Item #8. Page 869

C. That embody the distinctive characteristics of a type, period, or method of construction, or that represent the work of a master, or that possess high artistic values, or that represent a significant and distinguishable entity whose components may lack individual distinction; or D. That have yielded, or may be likely to yield, information important in prehistory or history.

Integrity is defined in NRHP guidance, “How to Apply the National Register Criteria,” as “the ability of a property to convey its significance. To be listed in the NRHP, a property must not only be shown to be significant under the NRHP criteria, but it also must have integrity” (NPS 1990). NRHP guidance further asserts that properties be completed at least 50 years ago to be considered for eligibility. Properties completed fewer than 50 years before evaluation must be proven to be “exceptionally important” (criteria consideration to be considered for listing.

State
California Register of Historical Resources
In California, the term “historical resource” includes but is not limited to “any object, building, structure, site, area, place, record, or manuscript which is historically or archaeologically significant, or is significant in the architectural, engineering, scientific, economic, agricultural, educational, social, political, military, or cultural annals of California” (California Public Resources Code Section 5020.1(j)). In 1992, the California legislature established the California Register of Historical Resources (CRHR) “to be used by state and local agencies, private groups, and citizens to identify the state’s historical resources and to indicate what properties are to be protected, to the extent prudent and feasible, from substantial adverse change” (California Public Resources Code Section 5024.1(a)). The criteria for listing resources on the CRHR were expressly developed to be in accordance with previously established criteria developed for listing in the NRHP, enumerated below. According to California Public Resources Code Section 5024.1(c)(1–4), a resource is considered historically significant if it (i) retains “substantial integrity,” and (ii) meets at least one of the following criteria:

Is associated with events that have made a significant contribution to the broad patterns of California’s history and cultural heritage.
(1) Is associated with events that have made a significant contribution to the broad patterns of California’s history and cultural heritage.
(2) Is associated with the lives of persons important in our past. (3) Embodies the distinctive characteristics of a type, period, region, or method of construction, or represents the work of an important creative individual, or possesses high artistic values. (4) Has yielded, or may be likely to yield, information important in prehistory or history.

In order to understand the historic importance of a resource, sufficient time must have passed to obtain a scholarly perspective on the events or individuals associated with the resource. A resource less than 50 years old may be considered for listing in the CRHR if it can be demonstrated that sufficient time has passed to understand its historical importance (see 14 CCR 4852(d)(2)).

The CRHR protects cultural resources by requiring evaluations of the significance of prehistoric and historic resources. The criteria for the CRHR are nearly identical to those for the NRHP, and properties listed or formally designated as eligible for listing in the NRHP are automatically listed in the CRHR, as are the state landmarks and points of interest. The CRHR also includes properties designated under local ordinances or identified through local historical resource surveys.

California Environmental Quality Act
As described further below, the following CEQA statutes and CEQA Guidelines are of relevance to the analysis of archaeological, historic, and tribal cultural resources:
• California Public Resources Code Section 21083.2(g) defines “unique archaeological resource.” • California Public Resources Code Section 21084.1 and CEQA Guidelines Section 15064.5(a) define “historical resources.” In addition, CEQA Guidelines Section 15064.5(b) defines the phrase “substantial adverse change in the significance of an historical resource.” It also defines the circumstances when a project would materially impair the significance of an historical resource. • California Public Resources Code Section 21074(a) defines “tribal cultural resources.” • California Public Resources Code Section 5097.98 and CEQA Guidelines Section 15064.5(e) set forth standards and steps to be employed following the accidental discovery of human remains in any location other than a dedicated ceremony.
• California Public Resources Code Sections 21083.2(b)-(c) and CEQA Guidelines Section 15126.4 provide information regarding the mitigation framework for archaeological and historic resources, including examples of preservation-in-place mitigation measures; preservation-in-place is the preferred manner of mitigating impacts to significant archaeological sites because it maintains the relationship between artifacts and the archaeological context and may also help avoid conflict with religious or cultural values of groups associated with the archaeological site(s).

More specifically, under CEQA, a project may have a significant effect on the environment if it may cause “a substantial adverse change in the significance of an historical resource” (California Public Resources Code Section 21084.1; CEQA Guidelines Section 15064.5(b).) If a site is either listed or eligible for listing in the CRHR, or if it is included in a local register of historic resources or identified as significant in a historical resources survey (meeting the requirements of California Public Resources Code Section 5024.1(q)), it is a “historical resource” and is presumed to be historically or culturally significant for purposes of CEQA (California Public Resources Code Section 21084.1; CEQA Guidelines Section 15064.5(a)). The lead agency is not precluded from determining that a resource is a historical resource even if it does not fall within this presumption (California Public Resources Code Section 21084.1; CEQA Guidelines Section 15064.5(a)).

A “substantial adverse change in the significance of an historical resource” reflecting a significant effect under CEQA means “physical demolition, destruction, relocation, or alteration of the resource or its immediate surroundings such that the significance of an historical resource would be materially impaired” (CEQA Guidelines Section 15064.5(b)(1); California Public Resources Code Section 5020.1(q)). In turn, CEQA Guidelines section 15064.5(b)(2) states the significance of an historical resource is materially impaired when a project:

1. Demolishes or materially alters in an adverse manner those physical characteristics of an historical resource that convey its historical significance and that justify its inclusion in, or eligibility for, inclusion in the California Register of Historical Resources; or

2. Demolishes or materially alters in an adverse manner those physical characteristics that account for its inclusion in a local register of historical resources pursuant to section 5020.1(k) of the Public Resources Code or its identification in an historical resources survey meeting the requirements of section 5024.1(g) of the Public Resources Code, unless the public agency reviewing the effects of the project establishes by a preponderance of evidence that the resource is not historically or culturally significant; or

3. Demolishes or materially alters in an adverse manner those physical characteristics of a historical resource that convey its historical significance and that justify its eligibility for inclusion in the California Register of Historical Resources as determined by a lead agency for purposes of CEQA.

Pursuant to these sections, the CEQA inquiry begins with evaluating whether a project site contains any “historical resources,” then evaluates whether that project will cause a substantial adverse change in the significance of a historical resource such that the resource’s historical significance is materially impaired.

If it can be demonstrated that a project will cause damage to a unique archaeological resource, the lead agency may require reasonable efforts be made to permit any or all of these resources to be preserved in place or left in an undisturbed state. To the extent that they cannot be left undisturbed, mitigation measures are required (California Public Resources Code Section 21083.2[a], [b], and [c]).

California Public Resources Code Section 21083.2(g) defines a unique archaeological resource as an archaeological artifact, object, or site about which it can be clearly demonstrated that without merely adding to the current body of knowledge, there is a high probability that it meets any of the following criteria:

1. Contains information needed to answer important scientific research questions and that there is a demonstrable public interest in that information.

2. Has a special and particular quality such as being the oldest of its type or the best available example of its type.

3. Is directly associated with a scientifically recognized important prehistoric or historic event or person.

Impacts to non-unique archaeological resources are generally not considered a significant environmental impact (California Public Resources Code section 21083.2(a); CEQA Guidelines Section 15064.5(c)(4)). However, if a nonunique archaeological resource qualifies as tribal cultural resource (California Public Resources Code Section 21074(c), 21083.2(h)), further consideration of significant impacts is required. CEQA Guidelines Section 15064.5 assigns special importance to human remains and specifies procedures to be used when Native American remains are discovered. As described below, these procedures are detailed in California Public Resources Code Section 5097.98.

2 Background Research

2.1 Cultural Resources Records Search
On June 28, 2019, Dudek completed a search of the CHRIS at the SCCIC, located on the campus of California State University, Fullerton of the proposed project APE and a half (0.5) mile buffer. This search included mapped prehistoric and historic archaeological resources and historic built-environment resources; Department of Parks and Recreation site records; technical reports; archival resources; and ethnographic references. Additional consulted sources included historical maps of the proposed project APE, the NRHP, the CRHR, the California Historic Property Data File, and the lists of California State Historical Landmarks, California Points of Historical Interest, and the Archaeological Determinations of Eligibility. The confidential records search results are also provided in Appendix B.

Previously Conducted Cultural Resource Studies
The SCCIC records indicate that seven (7) previous cultural resources technical investigations have been conducted within 0.50mile of the proposed project APE between 1988 and 2019. All seven technical investigations and are summarized in Table 1.

An Archaeological Survey Conducted on a Parcel of Land North of Palm Drive in the City of Glendora, Los Angeles County, California (Cottrell 1977) was an archaeological survey report conducted on the proposed project APE parcel in November 1977, prior to grading a portion of the site in anticipation of a residential development project.

The results of the field reconnaissance and record search were both negative, owing to a lack of visible resources in the southern portion of the survey area and to the dense vegetation present on the property in the drainage Item #8. Page 874

basins. The report does not record any historical features, but noted their presence and association either to the Silent Ranch/Rancho Los Alisos property or to the Girl Scout camp.

Previously Recorded Cultural Resources
The SCCIC records indicate that two cultural resources have been recorded within 0.5-mile of the proposed project APE; neither of which overlap or are located adjacent to the proposed project APE. One resource is the Angeles National Forest, which encompasses the entirety of the forest and one resource is a historic road. Both resources are summarized in Table 2.

2.2 Building Development Research
Los Angeles County Assessor
Dudek accessed the Los Angeles County Tax Assessor’s online Property Assessment Information System (PAIS) on August 15, 2019. The available reports from PAIS provided property information that included dates of construction.

The information from PAIS was used in the preparation of the historic context.

City of Glendora eTRAKit Online Permit System
Dudek accessed the City of Glendora’s online permitting system (eTRAKit) on August 14 and 15, 2019. Dudek collected permit information for 950 N Silent Ranch Drive and 935 N. Silent Ranch Drive (which contained information about the Aventura Girl Scout Camp). The available reports from PAIS provided property information that included dates of construction and alterations for structures built after 1950. The information from eTRAKit was used in the preparation of the historic context and identified alterations sections.

City of Glendora Public Library
On August 16, 2019, Dudek visited the Glendora Public Library to review sources relating to the history of Glendora.

These collections included photographs, books, and maps. Research at the Glendora Public Library was used in the preparation of the historic context.

On August 20, 2019, Dudek visited the Glendora Historical Society Museum to review items in the museum collection relating to the history of Glendora and collections for Silent Ranch. These collections included photographs, books, notebooks, pamphlets, advertisements, newspaper clippings and other archival materials.

Research at the Glendora Historical Society was used in the preparation of the historic context.

Aerial Photograph Review
Historic aerial photographs of the proposed project APE were available from Nationwide Environmental Title Research (NETR) LLC maps for the years 1953, 1964, 1965, 1972, 1977, 1978, 1980, 1994, 2002, 2003, 2004, 2005, 2009, 2012, and 2014, and from the University of California Santa Barbara (UCSB) Map and Imagery Laboratory for the years 1927, 1933, 1934, 1938, 1949, 1953, 1954, 1956, 1960, 1964, 1968, 1976, 1981 (NETR 2019a; UCSB 2019).

The earliest aerial photographs from 1927 show Judge Charles Silent’s Rancho Los Alisos. A circular fountain feature is located in the southeastern portion of the property, while the main house, outbuildings, and lawns are located loser to the western property boundary. The property is framed to the north by the vegetation at the base of the foothills. Some features appear in this vegetated area, such as a road cuts, footpaths, tree border, and a water cistern. The rest of the property is dominated by an evenly spaced, mature orchard.

The proposed project APE and surrounding area do not noticeably change in appearance or layout until the 1954 photograph. In the 1953 photograph the orchards that dominate the area south of the main house are present and densely arranged. In the 1954 photograph, some of the trees have been removed. By the 1956 aerial photograph, all of the orchard trees except two rows along the southern boundary on Palm Drive were removed. The tree lined access road was retained and a palm tree surrounded fountain/water feature in the southeastern property corner appears dry and infilled.

In the 1960 photograph, four buildings, and ten tent pads arranged in semi circles around the buildings appear in the southern section of the property, likely related to the Camp Aventura Girl Scout Camp. The northwestern corner of the property appears to have been subdivided into a separate property and in 1960 has a large, rectangular plan building with pool, driveway and fence along the property line. Another square plan building, located just north of the vegetated area in the northern portion of the property, also appears in the 1960 photograph, with a separate driveway leading to it. A large, square parking lot also appears in the southwestern corner of the property. Around the property is the Girls’ School to the west and several sports fields, but south of Palm Drive and east of Grand Avenue several residential subdivisions appear mid-construction. By the 1968 photograph, the water feature in the southeastern portion of the property appears overgrown. A fifth, very large irregular plan building appears north of the Camp Aventura buildings, as well as formal footpaths to the camp buildings and a separate driveway. Perhaps most meaningfully, the original Charles Silent Rancho Los Alisos-era ranch house and outbuildings are all removed in the 1968 photograph. By the 1976 photograph, a new house is under construction in the same location as the demolished Rancho Los Alisos-era house. The tent pads are no longer present at the Camp Aventura buildings and the paths between camp buildings appear disused and grown over. The large, rectangular-plan property just west also appears to have been demolished. The three concrete debris dams, and the concrete lined channel leading south from the east-most debris dam, are visible in the 1976 photograph. West of the proposed project APE and the Girls’ School buildings is the Hook Canyon debris dam and channel a significantly larger Los Angeles County Flood Control District debris dam, concrete lined flood control channel, and water tanks.

By the 1981 photograph, there are again drastic changes to the property. All of the visible Camp Aventura buildings appear demolished and land leveled, in the southern portion of the property, along Palm Drive. The square plan building situated in the vegetation in the western portion of the property appears demolished. The new ranch house building appears completed, and has a pool house, pool, and landscaped lawns and small immature orchard, northwest of the building. In the 1982 photograph, individual lot foundations and an access road are visibly under construction, creating a residential subdivision with 15 lots. By the next available photograph from 1994 and 1995, some, but not all lots appear to have construction activity and new buildings on them. By the 2003 photograph, all of the lots are filled. There are few other changes to the proposed project APE after 2003. Between the 2012 and 2014 photograph, the vegetation appears to have reduced in the canyon drainages, suggesting a fire.

Historical Map Review
A review of historic maps and aerial photographs was conducted as part of the archival research effort for the project. Sanborn Fire Insurance Company Maps were prepared for the City for the years 1910, 1928, and 1931; however, their coverage did not extend to the proposed project APE. An adjacent property, the Girls Collegiate School is on the 1931 Sanborn map, but no data for the proposed project APE is given. Topographic maps are available from NETR for the years 1897, 1898, 1902, 1904, 1908, 1912, 1923, 1925, 1927, 1932, 1933, 1939, 1941, 1946, 1955, 1957, 1960, 1964, 1968, 1975, 1999, 2012, and 2015. Additional topographic maps were available from the interactive USGS Historical Topographic Map Explorer website for the years 1894, 1897, 1897, 1901, 1904, 1925, 1927, 1933, 1939, 1953, 1966, 1972, and 1995.

The earliest topographical maps from 1894, 1897, and 1898 show two properties, marked by solid black squares near the northern terminus of Grand Avenue. There are few other markings in the proposed project APE, but the city boundaries of Glendora move incrementally north and west towards the proposed project APE until 1927, when four more structure symbols appear near the Grand Avenue terminus. Far north of the proposed project APE, the Morris Dam appears along the San Gabriel River, the major watershed of the area, creating a dam and several aqueducts in the area. In the 1939 topographic map, a water feature called the Metropolitan Aqueduct (Metropolitan Water District (MWD) Upper Feeder) appears in this topographic map for the first time, bisecting the proposed project APE. Six springs are also marked in the foothills northwest, north and northeast of the proposed project APE. The proposed project APE appears to have three structures, an unpaved road and a water reservoir on it. The Girls Collegiate School campus (later St. Lucy’s Priory School) appears north of the intersection of Barranca Avenue and Sierra Madre Avenue, west of the proposed project APE. In the 1966 topographic map, the Camp Aventura Girl Scout Camp appears. Also by the 1966 topographic map, the proposed project APE no longer appears to be on the rural fringes of Glendora, but rather a developed suburban community within the Glendora development limits. There are no radical changes to the proposed project APE or surrounding neighborhood after this according to topographical maps (NETR 2019b; USGS 2019).

3 Historical Context

3.1 Prehistoric and Ethnographic Overview
Prehistoric
Numerous chronological sequences have been devised to aid in understanding cultural changes within southern California. Building on early studies and focusing on data synthesis, Wallace (1955, 1978) developed a prehistoric chronology for the Southern California coastal region that is still widely used today and is applicable to near-coastal and many inland areas. Four periods are presented in Wallace’s prehistoric sequence: Early Man (Horizon I), Milling Stone (Horizon II), Intermediate (Horizon III), and Late Prehistoric (Horizon IV). The earliest accepted dates for occupation are from two of the northern Channel Islands, located off the coast of Santa Barbara. On San Miguel Island, Daisy Cave clearly establishes the presence of people in this area about 10,000 years ago (Erlandson 1991).

Recent data from Horizon I sites indicate that the economy was a diverse mixture of hunting and gathering, with a major emphasis on aquatic resources in many coastal areas and on Pleistocene lakeshores in eastern San Diego County (see Moratto 1984). The Milling Stone Horizon of Wallace (1955, 1978) and Encinitas Tradition of Warren (1968) (6000–3000 BC) are characterized by subsistence strategies centered on collecting plant foods and small animals. Following the Milling Stone Horizon, Wallace’s Intermediate Horizon and Warren’s Campbell Tradition in Santa Barbara, Ventura, and parts of Los Angeles Counties, date from approximately 3000 BC to AD 500 and are characterized by a shift toward a hunting and maritime subsistence strategy, along with a wider use of plant foods.

In the Late Prehistoric Horizon (Wallace 1955, 1978), which lasted from the end of the Intermediate (ca. AD 500) until European contact, there was an increase in the use of plant food resources in addition to an increase in land and sea mammal hunting. There was a concomitant increase in the diversity and complexity of material culture during the Late Prehistoric.

Ethnographic
The proposed project APE is in an area historically occupied by the Gabrielino. The archaeological record indicates that the Gabrielino arrived in the Los Angeles Basin around 500 BC. Many contemporary Gabrielino identify themselves as descendants of the indigenous people living across the plains of the Los Angeles Basin and adjacent areas. The name “Gabrielino” denotes those people who were administered by the Spanish from the San Gabriel Mission, which included people from the Gabrielino area proper as well as other social groups (Bean and Smith 1978; Kroeber 1925). Many modern Gabrielino identify themselves as descendants of the indigenous people living across the plains of the Los Angeles Basin and refer to themselves as the Tongva (King 1990), while others reject this term. Gabrielino lands encompassed the greater Los Angeles Basin and three Channel Islands, San Clemente, San Nicolas, and Santa Catalina. The Gabrielino established large, permanent villages in the fertile lowlands along rivers and streams, and in sheltered areas along the coast, stretching from the foothills of the San Gabriel Mountains to the Pacific Ocean. A total tribal population has been estimated of at least 5,000 (Bean and Smith 1978), but recent ethnohistoric work suggests a number approaching 10,000 (O’Neil 2002).

British explorers visited the area for brief periods between 1529 and 1769, the Spanish Period in California begins with the establishment in 1769 of a settlement at San Diego and the founding of Mission San Diego de Alcalá, the first of 21 missions constructed between 1769 and 1823. In 1771, a fourth mission was founded at the Mission San Gabriel Arcángel by a Portola expedition. The original 1771 mission was destroyed in a flash flood and a new mission was built in 1776. El Pueblo de Nuestra Señora la Reina de Los Ángeles, further west, was established in 1781 to support Mission San Gabriel Arcángel. The San Gabriel Mission lands extended from Los Angeles east as far as San Bernardino de Sena Estancia (established 1810), and the San Bernardino Valley, including present day Irwindale, would have been under Mission San Gabriel Arcángel control (Caughey and Caughey 1977; Gumprecht 2001).

After more than a decade of intermittent rebellion and warfare, New Spain (Mexico and the California territory) won independence from Spain in 1821. In 1822, the Mexican legislative body in California ended isolationist policies designed to protect the Spanish monopoly on trade, and decreed California ports open to foreign merchants.

Mexican governors established extensive land grants throughout interior California during the Mexican Period, in part to wrest secular control away from the Spanish Missions and to give land as a reward to soldiers in lieu of pension. Land grants were also a way to disperse the population away from the more settled coastal areas and take advantage of cattle and agricultural industry. Mexican governor Juan Alvarado awarded Rancho El Susa to Luis Arenas and Rancho Azusa de Duarte to Andres Duarte in 1841. Just three years later, in 1844 Arenas sold onethird interest in Rancho San Jose to Englishman and merchant Henry Dalton. Dalton also acquired the San Jose Addition, and Rancho Azusa in 1844, and renamed his acquired lands Rancho Azusa de Dalton (Figure 3) (Caughey and Caughey 1977; Dallas 1955; Lewis Publishing Co. 1889; Zerneke 2009).

The Mexican Period ended with the signing of the Treaty of Guadalupe Hidalgo in 1848, ending the MexicanAmerican War, which signals the beginning of the American Period when California became a territory of the United States. California officially became a state with the Compromise of 1850, which also designated Utah and New Mexico (with present-day Arizona) as U.S. Territories. After the Treaty of Guadalupe Hidalgo in 1848, Henry Dalton lost the majority of his assets and was forced to live the rest of his life in poverty (City of Glendora 1999; Lewis Publishing Co. 1889; Waugh 2003).

Dalton’s claims were partitioned and sold off and in the 1860s four homesteads along the foothills belonging to John Gassaway, John Harrar, Coleman Barnes, and Leonidas Barnes were recorded. In 1874, John Bender and William Bryant Cullen homesteaded 160 acres within what would become Glendora. They were soon joined by other homesteading families including Shorey, Preston, Wright, Griece, Washburn, Englehart, LaFetra, Johnson, and West.

The homesteads produced wheat, flax, barley, caster beans, potatoes other vegetables, grapevine orchards and fruit trees. Crops were sold in markets in either Los Angeles or San Bernardino, both near 2-days wagon ride away.
