NOTICE OF INTENT TO ADOPT A MITIGATED NEGATIVE DECLARATION In compliance with the California Environmental Quality Act (CEQA), the Morgan Hill Unified School District has undertaken environmental review for the proposed Borello Site Acquisition located at Peet Road and Mission Avenida, and intends to adopt a Mitigated Negative Declaration. The Morgan Hill Unified School District invites all interested persons and agencies to comment on the proposed Borello Site Acquisition Mitigated Negative Declaration. Lead Agency: Morgan Hill Unified School District Project Location: The 12.04-acre project site is located at the northeast corner of the intersection of Peet Road and Mission Avenida in the City of Morgan Hill, Santa Clara County, California. Project Description: The Morgan Hill Unified School District has been offered ten acres of a 12.04- acre property in the City of Morgan Hill for a future school facility. The School District is considering acquisition of the property; however, no plans for development of the site have been identified. The project site would be large enough to accommodate an elementary school or some other type of School District facility, such as a sport’s facility, but is not large enough for either a middle school or traditional high school.

  • Appendix B Biological Evaluation
    Appendix B Biological Evaluation UHC MORGAN HILL BIOLOGICAL EVALUATION CITY OF MORGAN HILL, CALIFORNIA Prepared by LIVE OAK ASSOCIATES, INC. Rick Hopkins, Ph.D., Principal and Senior Wildlife Ecologist Davinna Ohlson, M.S., Senior Project Manager and Plant/Wildlife Ecologist Arren Allegretti, Ph.D., Plant Ecologist Prepared for A0702 Morgan Hill L.P. Attn: Mark Irving 2000 E Fourth St. #205 Santa Ana, CA 92705 September 3, 2020 PN 2478‐01 UHC Morgan Hill BE PN 2478‐01 EXECUTIVE SUMMARY Live Oak Associates, Inc. (LOA) examined the biological resources of the approximately 3.7‐acre UHC Morgan Hill project site (“site”) plus an additional 0.9 acres of off‐site improvements. LOA evaluated possible impacts to these biological resources resulting from the development of affordable rental housing units (“project”). The site is located on Watsonville Road, approximately one mile west of Highway 101 in the City of Morgan Hill, Santa Clara County, California. Habitat and land use types occurring in the site include developed areas, ruderal fields, and a retention basin that is a relict from a former mushroom production facility. Sensitive natural communities are absent from the site and subsequently no impacts to these communities are anticipated. The site does not serve as a wildlife movement corridor, although wildlife may use the site as part of their typical dispersal movements to higher‐quality habitats in the region. Site development is not expected to have a significant effect on home range and dispersal movements of native wildlife that may occur in the region. Special status species that may occur on the site include the white‐tailed kite, loggerhead shrike, Townsend’s big eared bat, and pallid bat.

T. Harvey & Associates June 28, 2019 983 University Avenue, Building D Los Gatos, CA 95032 Ph: 408.458.3200 F: 408.458.3210 Executive Summary The Peninsula Open Space Trust (POST) and Santa Clara Valley Open Space Authority (SCVOSA) are working with other conservation partners in an effort to acquire, preserve, and eventually enhance and restore strategic locations within the Coyote Valley of Santa Clara County, California. Currently, POST and SCVOSA are considering the acquisition of approximately 903 acres owned by The Sobrato Companies and Brandenburg Properties in North Coyote Valley. The purpose of this report is to describe existing biological resources on these properties, as well as potential opportunities for creation, restoration, and enhancement of native habitat, including habitat connectivity. Important existing biological resources in the study area include the following: • Extensive wetland, aquatic, and riparian resources, including seasonal wetland (113.95 acres), potential seasonal wetland (23.67 acres), coastal and valley freshwater marsh (9.46 acres), mixed riparian forest/scrub and freshwater marsh (16.02 acres), mixed riparian forest and willow riparian forest (23.03 acres), and pond (5.48 acres) habitats • Laguna Seca, the largest freshwater wetland area in the Santa Clara Valley • High-quality mixed oak

  • PRELIMINARY GEOLOGIC DESCRIPTION of the SAN JOSE 30 X 60 MINUTE QUADRANGLE. CALIFORNIA Carl M. Wentworth, M. Clark Blake, Jr., R
    U.S. DEPARTMENT OF THE INTERIOR U.S. GEOLOGICAL SURVEY PRELIMINARY GEOLOGIC DESCRIPTION OF THE SAN JOSE 30 X 60 MINUTE QUADRANGLE. CALIFORNIA By Carl M. Wentworth, M. Clark Blake, Jr., Robert J. McLaughlin, and Russell W. Graymer Part 3 of Open-File Report 98-795 1999 This report is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards or with the North American Stratigraphic Code. Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government. INTRODUCTION The San Jose 30 x 60 minute quadrangle (figure 1), which contains the city of San Jose near its northwest corner, straddles the central California Coast Ranges and much of the San Andreas fault system southeast of San Francisco. The quadrangle extends from near the town of Santa Cruz on the southwest (long. -122°, lat. 37°) to the San Joaquin River in the San Joaquin Valley on the northeast (long. -121°, lat. 37.5°), a diagonal distance across the structural grain of the area of just over 100 km (65 mi). This new geologic compilation is based on extensive previous work by many authors and a great deal of new mapping, largely at a scale of 1:24,000, much of which is previously unpublished. The report remains preliminary because of the absence of structural data including attitudes and concealed faults beneath the Santa Clara and San Joaquin Valleys, the inconsistent treatment of landslides, and the need for further modification, particularly in the Quaternary of the Santa Clara Valley.
