55 <br /> <br />3.3.1 Conflict with an Adopted Habitat Conservation Plan <br />Potential Impact. There are no adopted Habitat Conservation Plans that cover the site <br />(however, see Section 3.3.14 regarding the East Alameda County Conservation Strategy). <br />Mitigation. None required. <br />3.3.2 Potential Impacts to California Tiger Salamander Habitat and Individuals <br />Potential Impact. Although breeding habitat is absent from the site, there are five breeding <br />ponds reported in the CNDDB that are within 1.2 miles from the site. One of these latter ponds <br />has been extirpated as a breeding site due to an earthen dam failure. Breeding ponds exist to the <br />southeast and north of the site, and the Olberding 2008 report includes two additional sightings: a <br />2006 sighting of two adults in a seep in the northern portion of the East Side Conservation Area <br />within the Callippe Golf Course and a 1999 sighting in a neighbor’s pond which is located to the <br />north of the present site boundaries. Additionally, Marcia Grefsrud/CDFW has indicated that <br />there have been more recent observances of breeding CTS in a pond, wetland and seep located <br />within the East Side Conservation Area, with the closest observance being within 0.31 miles of <br />the proposed development and slope stabilization areas of the Spotorno Ranch development site. <br /> <br />Dr. Mark Jennings completed surveys of the site in 2012 and 2015 to assess the suitability of the <br />site to support habitat for California tiger salamanders. He examined the project site, as well as <br />potential aquatic habitats in the surrounding vicinity (where accessible). He determined that none <br />of the seasonal wetlands on the site supported appropriate hydrology to provide breeding habitat <br />for CTS, and he also observed that a former aquatic pond adjacent to the site (on private property) <br />no longer exists; and that former California tiger salamander breeding habitat on adjacent Lund <br />Ranch had been eliminated for at least 8 years as of his 2015 survey. <br />Additionally, according to the owner Al Spotorno, he and family members have conducted <br />California ground squirrel (Spermophilus beecheyi) control for decades to keep livestock from <br />potentially stepping in burrows and injuring themselves; and the fields on his property are disked <br />to grow hay and legumes, upon which livestock are turned out to feed, on an annual basis.
