T. Harvey & Associates ii Biotic Report Addendum February 2016 Section 1. Introduction On behalf of Blair, Church & Flynn, H. T. Harvey & Associates performed a desktop review and reconnaissance survey of environmental conditions and biological resources for the revised site plan for the Tenaya Lodge Explorer Cabins Project, in Fish Camp, Mariposa County (Figure 1). This report, which serves as an addendum to the project’s biotic report (H. T. Harvey & Associates 2014), presents a supplemental analysis of impacts within new areas encompassed by the revised site plan (Appendix A) for incorporation into the primary analysis prepared for the project in compliance with the California Environmental Quality Act (CEQA). This report also provides an update to the project description (Section 2.0). In summary, the project site was revised to include a utility corridor between the proposed Explorer Cabins site and existing Tenaya Lodge facilities, improvements to a portion of Highway 41, and a half-acre dedicated parcel (Parcel 2) that would remain a residential lot (Figure 2, Appendix A). The utility corridor would have water lines and containment structures, sewer lines connecting to the Tenaya Lodge wastewater treatment system, and telecommunications lines.
