be established around these roost sites until they are determined to be no <br /> longer active by the qualified biologist. A 100-foot no disturbance buffer <br /> is a typical protective buffer distance; however, buffer width may be <br /> modified by the qualified biologist depending on existing screening <br /> around the roost site(such as dense vegetation or a building) as well as the <br /> type of construction activity which would occur around the roost site. <br /> • The qualified biologist shall be present during tree and structure removal <br /> if potential bat roosting habitat or active bat roosts are present. Trees and <br /> structures with active roosts shall be removed only when no rain is <br /> occurring or is forecast to occur for 3 days and when daytime temperatures <br /> are at least 50°F. <br /> • Removal of trees with potential bat roosting habitat or active bat roost <br /> sites shall follow a two-step removal process: <br /> 1. On the first day of tree removal and under supervision of the <br /> qualified biologist, branches and limbs not containing cavities or <br /> fissures in which bats could roost, shall be cut only using <br /> chainsaws. <br /> 2. On the following day and under the supervision of the qualified <br /> biologist,the remainder of the tree may be removed, either using <br /> chainsaws or other equipment(e.g. excavator or backhoe). <br /> Removal of structures containing or suspected to contain potential bat roosting <br /> habitat or active bat roosts shall be dismantled under the supervision of the <br /> qualified biologist in the evening and after bats have emerged from the roost to <br /> forage. Structures shall be partially dismantled to significantly change the roost <br /> conditions, causing bats to abandon and not return to the roost. <br /> Site(s) affected: All sites where buildings shall be demolished or large trees <br /> constituting suitable habitat for roosting bats shall be removed. <br /> (Draft SEIR,pp. 4.E-9 to 4.E-14.) <br /> Impact 4.E-[c <br /> Development facilitated by the Project could potentially have a substantial adverse effect <br /> on federally protected wetlands. <br /> The Revised Final SEIR evaluates the impact of the Project on wetlands, including <br /> wetlands present in the Alamo Canal adjacent to the area of the Project. <br /> Significance Before Mitigation: Significant <br />
