Hamilton Biological H AMILTON B IOLOGICAL February 8, 2021 Everett DeLano DeLano & DeLano 220 West Grand Avenue Escondido, CA 92025 SUBJECT: REVIEW OF BIOLOGICAL RESOURCE ISSUES TRAILS AT CARMEL MOUNTAIN RANCH DRAFT EIR CITY OF SAN DIEGO Dear Mr. DeLano, At your request, Hamilton Biological, Inc., has reviewed the Draft EIR (DEIR) for the proposed Trails at Carmel Mountain Ranch project, located in the City of San Diego, San Diego County, California. I reviewed relevant portions of the DEIR’s Section 5.4 (Biological Resources) and Ap- pendix J (Biological Resources Technical Report). Hamilton Biological is a consultancy specializing in field reconnaissance, regulatory compliance, preparing CEQA documentation, and providing third-party review of CEQA documentation. This review has the following purposes: • To identify any areas in which the document reaches conclusions not supported by adequate field work or thorough review of the scientific literature. • To identify and discuss any biological impact analyses not consistent with CEQA, its guidelines, or relevant precedents. • To evaluate the project alternatives to determine whether one or more of them may better protect sensitive biological resources. • To recommend changes to impact analyses, mitigation measures, and/or resource management practices to avoid or minimize to the maximum extent practicable po- tentially significant impacts to biological resources, as required under CEQA. FIELD VISIT As part of my evaluation of the DEIR and its adequacy, I visited portions of the project site with botanist James Bailey on January 22, 2021, from 11:30 a.m. to 3:10 p.m. Tem- perature was 63–59° F; wind was 3–6 mph; cloud cover was approximately 90 percent. The purpose of the field visit was to review portions of the project site to evaluate the accuracy and adequacy of the DEIR’s information. 316 Monrovia Avenue Long Beach, CA 90803 562-477-2181 [email protected] Review of Biological Issues, Trails at Carmel Mountain Ranch DEIR Hamilton Biological, Inc. February 8, 2021 Page 2 of 21 INADEQUATE SURVEY EFFORT VIOLATES CITY’S BIOLOGY GUIDELINES Page 7 in the Biological Resources Technical Report (Appendix I to the DEIR) describes the survey effort for the DEIR: Biological field surveys for the proposed project were conducted in July and August 2019, by Dudek biologists Patricia Schuyler, Tricia Wotipka, and Olivia Koziel. Field surveys in- cluded vegetation and land cover mapping, habitat quality assessment, and jurisdictional resource delineation. Table 1 lists the survey dates, times, surveying biologists, and weather conditions during the survey. As documented herein, the four days of biological surveys conducted in summer 2019 (July 8, July 19, August 8, and August 22) failed to adequately document the plant and wildlife species present, or potentially present, on the site. Plant Surveys Inadequate The DEIR’s Plant Compendium, listing all of the plant taxa observed on the project site, contains only 22 native taxa and 20 non-native taxa (Washingtonia filifera is erroneously listed as a native species), for a total of 42 taxa. During a site visit lasting less than four hours, on January 22, 2021, Hamilton Biological observed 52 native taxa, 73 non-native taxa, and one taxon of uncertain provenance, for a total of 126 taxa. We observed the following taxa on the site, including four special- status species not recorded by the project biologists (California Native Plant Society [CNPS] rankings are indicated for those taxa, with footnotes explaining the CNPS Rank- ings, as defined by CNPS).

Box 2460), Saudi Arabia *corresponding author: [email protected] Received 18 August 2015; accepted 07 October 2015 A b s t r a c t The aim of the current study was to determine the floral phenology, nectar secretion dynamics, and honey production potentials of two naturally growing lavender species (L. dentata and L. pubescens), in southwestern Saudi Arabia. In both species, flowering is continuous. This means that, when open flowers on a spike are shaded, new flowers emerge. Such a flowering pattern might be advantageous to the plant to minimise competition for pollinators and promote efficient resource allocation. The flowering periods of the two species overlap. Both species secreted increasing amounts of nectar from early morning to late afternoon. The mean maximum volumes of accumulated nectar from bagged flowers occurred at 15:00 for L. pubescens (0.50 ± 0.24 µL/flower) and at 18:00 for L. dentata (0.68 ± 0.19 µL/flower). The volume of the nectar that became available between two successive measurements (three-h intervals) varied from 0.04 µL/flower to 0.28 µL/flower for L.

  • Ventura County Plant Species of Local Concern
    Checklist of Ventura County Rare Plants (Twenty-second Edition) CNPS, Rare Plant Program David L. Magney Checklist of Ventura County Rare Plants1 By David L. Magney California Native Plant Society, Rare Plant Program, Locally Rare Project Updated 4 January 2017 Ventura County is located in southern California, USA, along the east edge of the Pacific Ocean. The coastal portion occurs along the south and southwestern quarter of the County. Ventura County is bounded by Santa Barbara County on the west, Kern County on the north, Los Angeles County on the east, and the Pacific Ocean generally on the south (Figure 1, General Location Map of Ventura County). Ventura County extends north to 34.9014ºN latitude at the northwest corner of the County. The County extends westward at Rincon Creek to 119.47991ºW longitude, and eastward to 118.63233ºW longitude at the west end of the San Fernando Valley just north of Chatsworth Reservoir. The mainland portion of the County reaches southward to 34.04567ºN latitude between Solromar and Sequit Point west of Malibu. When including Anacapa and San Nicolas Islands, the southernmost extent of the County occurs at 33.21ºN latitude and the westernmost extent at 119.58ºW longitude, on the south side and west sides of San Nicolas Island, respectively. Ventura County occupies 480,996 hectares [ha] (1,188,562 acres [ac]) or 4,810 square kilometers [sq. km] (1,857 sq. miles [mi]), which includes Anacapa and San Nicolas Islands. The mainland portion of the county is 474,852 ha (1,173,380 ac), or 4,748 sq.
