<br />EXPLANATION:
<br />a-b)The California Natural Diversity Database (CNDDB) for the U.S. Geological Survey (USGS) San Leandro, Hayward,
<br />Oakland East, Oakland West, Las Trampas Ridge and Newark 7.5 -minute quadrangles identifies 82 special -status plant
<br />and animal species, and four sensitive natural communities in the database. This includes species listed as rare,
<br />threatened, endangered, or proposed for listing as such, under the California and Federal Endangered Species Acts,
<br />species of special concern to California Department of Fish and Game (CDFG), and plants on the California Native Plant
<br />Society (CNPS) list 1 Or 2 (considered rare or endangered within California and elsewhere). The extensive species lists
<br />generated by the CNDDB and CNPS queries are the result of populations of sensitive species associated with freshwater
<br />wetlands and undisturbed native grasslands found within the region (primarily east of the project sites); and species
<br />associated with the brackish and freshwater habitats of San Francisco Bay (approximately two miles west of the project
<br />sites).
<br />Site 1 is a previously graded and disturbed property located at the northeast corner of San Leandro Blvd and West
<br />Juana Avenue and is currently a square shaped asphalt parking lot with no permanent building structures. The site
<br />does contain mature, ornamental landscaping around the site perimeter. A Tree Report prepared by Hortscience
<br />(October, 2008) identified all trees on the subject property over six inches in diameter. Forty-seven trees were
<br />surveyed on the site, representing five species, including Holly Oak (23), Sweet Gum (18), Camphor (4) and Tree of
<br />Heaven (1) and Honey Locust (1). Twenty two (22) of the Holly Oaks along San Leandro Boulevard and four (4) of
<br />the interior trees will be impacted by the proposed project. The tree report recommended the removal of up to thirty
<br />(3) trees. The site plan will allow for preservation of up to seventeen trees, including seven of the Sweet Gums along
<br />W. Juana Avenue, nine of the Sweet Gums along Carpentier Street and one Tree of Heaven_
<br />Mitigation Measure #18: The applicant shall follow the tree preservation guidelines set forth in the October,
<br />2008 Hortscience Tree Report, including having the consulting arborist review all project plans with regard to
<br />tree impacts and implementation of necessary protection measures and avoiding grading, construction,
<br />demolition or other work within designated, on-site Tree Protection Zones.
<br />An examination of the limited number of trees and shrubs on site during the field investigation did not reveal the
<br />presence of any nests of birds protected by the Migratory Bird Treaty Act. However, any project activities that would
<br />result in the removal of existing woody vegetation could potentially impact nesting birds (i.e., the loss of young birds or
<br />the abandonment of an active nest), which would be a violation of Fish and Game Code Section 3503 and the federal
<br />Migratory Bird Treaty Act and would be a potentially significant impact. The mitigation measure below would reduce
<br />potential impacts to nesting birds to a less -than -significant level.
<br />Mitigation Measure #19: The applicant shall conduct pre -construction surveys for the presence of nesting birds
<br />within each of the project sites. The project applicant shall retain a qualified biologist to conduct a pre -
<br />construction breeding -season survey (approximately February 1 through August 31) to determine if any birds are
<br />nesting on or directly adjacent to the project area. The survey shall be conducted during the same calendar year
<br />that construction is planned to begin. If no nesting birds are found, then no further action would be required. If
<br />nesting birds are found within the trees on or directly adjacent to the project area, the project applicant shall
<br />avoid all birds nest sites located in the project area during the breeding season (approximately February 1
<br />through August 31), or until it is determined by a qualified biologist that all young have fully fledged (left the
<br />nest). If the construction cannot be delayed, avoidance shall include the establishment of a non -disturbance buffer
<br />zone around the nest site. The size of the buffer zone will be determined in consultation with the CDFG. The
<br />buffer zone shall be delineated by highly visible temporary construction fencing, and shall remain in place until it,
<br />is determined by a qualified biologist that all young have fully fledged (left the nest).
