The report has been prepared to support compliance with the California Environmental Quality Act (CEQA) documentation including the preparation of an Environmental Impact Report (EIR) and environmental review process conducted by the City of Duarte, California. As discussed below, the assessment included a thorough literature review, site reconnaissance characterizing existing conditions (including floral, faunal and dominant vegetation communities), impact analysis, and development of proposed mitigation measures to reduce impacts to a level of less than significant. As stated by PlaceWorks: “The project applicant, City of Hope National Medical Center (City of Hope), is seeking approval of the City of Hope Campus Plan, which through a comprehensive Specific Plan would provide direction for the enhancement and development of the City of Hope campus over a period of 20 years, including the replacement of existing outdated and/or obsolete buildings with modern facilities. Specifically, City of Hope proposes additions to the existing outpatient (clinic), inpatient (hospital), research, office, industrial, warehouse, and hospitality uses at its main campus. New parking structures, surface parking lots, internal roadways, pedestrian and open space improvements are also proposed. Improvements would support the applicant’s efforts to expand its research and treatment capabilities in order to ensure continued advances in the treatment and research of cancer, diabetes, and other life-threatening diseases, while accommodating the needs of patients and their families, faculty, staff, and the community. The Specific Plan would be a guide and vision for the long-term improvements that will enable City of Hope to meet its commitment to transform the future of medicine.” (PlaceWorks 2015) PROJECT LOCATION The 116-acre Project Site is located completely within Los Angeles County near the base of the San Gabriel Mountains, immediately south of Interstate 215 and west of Interstate 605 as shown in Figure 1, Regional Location Map. Specifically, the Project Site is primarily located in the City of Duarte (89.5 acres) and partially within the City of Irwindale (26.5 acres) as shown in Figure 2, Project Site Map. The Project Site is bordered by Duarte Road to the north, Cinco Robles and Buena Vista Street on the western boundary, and the Santa Fe Flood Control Basin to the east and south.

D-6 PROJECT DESCRIPTION The project applicant is seeking approval of a Specific Plan developed for City of Hope Campus for the purpose of providing direction for enhancement and development over a 20-year period. As stated by PlaceWorks: “City of Hope (project applicant) is seeking approval of a Specific Plan, which would provide comprehensive direction for enhancement and development of its approximately 116-acre campus (less than one half acre is not owned by City of Hope) adjacent to the campus over a 20-year period. City of Hope proposes additions to the existing outpatient (clinic), inpatient (hospital), research, office, industrial, warehouse, and hospitality uses. New parking structures and surface parking lots are also proposed, as well as internal driveways and open space improvements. These changes and improvements throughout the campus would be implemented primarily through the Specific Plan, which would govern future development of the campus, supporting City of Hope’s efforts to expand its research and treatment capabilities, while accommodating the needs of patients and their families, faculty, staff, and the community.” (PlaceWorks 2015) METHODOLOGY The following section details the methods implemented prior and during the reconnaissance survey conducted throughout the Project Site. LITERATURE REVIEW Existing biological resource conditions within and adjacent to the Project Site were initially investigated through review of pertinent scientific literature. Federal register listings, protocols, and species data provided by the United States Fish and Wildlife Service (USFWS) were also reviewed in conjunction with anticipated federally listed species potentially occurring within the region of the Project Site. The California Natural Diversity Database (CNDDB) (CDFW 2016a), a California Department of Fish and Wildlife (CDFW) Natural Heritage Division species account database, was also reviewed for all pertinent information regarding the locations of known occurrences of sensitive species in the vicinity of the property. In addition, numerous regional floral and faunal field guides were utilized in the identification of species and suitable habitats. Combined, the reviewed sources provided an excellent baseline from which to inventory the biological resources potentially occurring in the area. Other sources of information included the review of unpublished biological resource letter reports and assessments. Other CDFW reports and publications consulted include the following: Special Animals (CDFW 2016b); Special Vascular Plants and Bryophytes List (CDFW 2016c); Endangered, Threatened, and Rare Plants of California (CDFW 2016d); and State and Federally Listed Endangered and Threatened Animals of California (CDFW 2016e); Biological Resources Technical Report City of Hope Campus Plan Cadre Environmental February 2017 4 D-7 FIELD SURVEY A reconnaissance survey of the Project Site was conducted by Ruben Ramirez of Cadre Environmental on January 21st, 2016 in order to characterize and identify potential sensitive plant and wildlife habitats, and to establish the accuracy of the data identified in the literature search. Geologic and soil maps were examined to identify local soil types that may support sensitive taxa. Aerial photograph, topographic maps, vegetation and rare plant maps prepared for previous studies in the region were used to determine community types and other physical features that may support sensitive plants/wildlife, uncommon taxa, or rare communities that occur within or adjacent to the Project Site. Habitat assessments were conducted for, but not limited to, the following target species/groups. Coastal California gnatcatcher – FT/SSC Least Bell’s vireo – FE/SE Southwestern willow flycatcher – FE/SE Sensitive plants Protected street trees (City of Duarte Municipal Code, Chapter 13.08) Vegetation Communities/Habitat Classification Mapping Natural community names and hierarchical structure follows the CDFW “List of California Terrestrial Natural Communities” and/or Holland (1986) classification systems, which have been refined and augmented where appropriate to better characterize the habitat types observed onsite.

  • Final Draft Master Plan
    January 2016 Final Draft Master Plan Claremont Hills Wilderness Park PREPARED BY MIG City of Claremont January 2016 CHAPTER 1: INTRODUCTION 1.1 BACKGROUND The purpose of the Claremont Hills Wilderness Park (CHWP) Master Plan is to guide the management of the 2,000-acre park owned by the City of Claremont, a community of approximately 35,000 in east Los Angeles County. The CHWP is located in the foothills of the San Gabriel Mountains adjacent to the southern edge of the Angeles National Forest. It receives half a million visits annually from across the region (Exhibit 1). The proximity to the 10 and 210 freeways and regionally serving arterials provide convenient access for visitors. The park has multiple access points, with its busiest entrance located at the northern terminus of N. Mills Ave. The original trail network is comprised of Los Angeles (LA) County fire roads, which can be navigated with relative ease by users of different experience levels. The trail system cuts through hilly terrain with spectacular views across the valley to the south and majestic Mt. Baldy to the north (Exhibit 2). In 1996, the City of Claremont agreed with Pomona College to accept a gift of land from Hermann Garner’s Padua Trust, which was the original 1,225 acres that formed the CHWP. Shortly after, the City adopted a management plan to serve as the primary steering document to guide park management. However, as popularity of the park grew rapidly, becoming a regional destination, safety concerns and neighborhood impacts became topics of increasing community dialogue.

From: Juan J. Hernandez Subject: Updated Biological Assessment for Francis Avenue Residential Development Project located in the City of Chino, San Bernardino County, California Pursuant to your request, Hernandez Environmental Services (HES) conducted a biological assessment to document existing biological conditions associated with development of the Francis Avenue Residential Development Project site, consisting of approximately 13.35 acres located at 4570 Francis Avenue in the City of Chino, San Bernardino County, California (Figures 1 and 2). The proposed Francis Avenue Residential Development Project would result in the construction of a residential development and associated infrastructure on the entire 13.35-acre site. The project site is located within the City of Chino. The site encompasses an approximate 13.35-acre area generally located north of the intersection of Francis Avenue and Yorba Avenue. The project site consists of roofed animal pens, concrete pads, and a storage building. The site is relatively flat with an elevation of approximately 850 feet above mean sea level (amsl). A single soil type, Tujunga loamy sand, occurs on the site. The project site is surrounded by residential land uses to the east, south, and west. A General Biological Resources Assessment was prepared for the project by Psomas in July of 2016 (Appendix B). According to the previous study, the project site consists of developed and disturbed areas. The developed areas consist of roofed animal pens, concrete pads, and a storage building The disturbed areas consist of those areas with no concrete or pavement, exhibiting bare soil or sparse vegetation subject to vegetation management pursuant to Chapter 15.32 (specifically, Section 504.1.2 Vegetation) of the City of Chino Municipal Code.
