Required setbacks from a creek will be established by the City of Pleasanton and will be guided by the geological stability and habitat significance of a creek to the City. HCPs/NCCPs No known habitat conservation plans are in effect for this property. 3.3 ENVIRONMENTAL IMPACT/MITIGATION Figure 8 depicts the Spotorno Ranch site plan overlaid on habitats of the site. The project will result in permanent impacts to approximately 28 to 30 acres of primarily grasslands used for hay production as a result of the development of the homes and associated infrastructure. The additional slope stabilization will result in impacts to approximately 4.25 acres, including 0.02 acres of seasonal wetlands. Although no specifics plans were available at the time of the preparation of this document, and details are not provided on Figure 8, there will be some additional impacts as a result of the project occurring in the common parcel along Alisal Street. These project elements will include trenching for the installation of a pipeline to convey stormwater from a proposed detention pond to an existing culvert near Alisal Street as well as construction of an emergency vehicle access road (EVA). Alignments for these latter two elements are still being determined, but potentially these project elements could impact the large seasonal wetland (Wetland 4) occurring within the common parcel. Potential impacts are discussed in greater detail below.
