65 It should be noted that the Congdon’s tarplant is a focal species under the EACCS and the EACCS includes a standardized mitigation ration for this species of 5:1. General and species- specific avoidance and minimization measures included in the EACCS Biological Opinion which also will be implemented are included in Appendix B. 3.3.9 Potential Impacts to Riparian Habitat and Other Sensitive Natural Communities, Including Federally Protected Wetlands Potential Impact. Two wetland delineations have been conducted on the site, one by Olberding in 2008 which was subsequently verified by USACE, and one by LOA in January and April 2015. The second delineation was conducted due to the expiration of the Jurisdictional Determination (JD) for the prior delineation and because it appeared that the condition of wetlands on the site had changed since the 2008 delineation. A site verification visit was conducted with Keith Hess/USACE on June 30, 2016, however, although a new JD is forthcoming, at the time of the preparation of this report, it had not yet been issued by USACE. None the less, the final map submitted to USACE for verification arose from findings from the verification site visit and therefore will be the map on which the JD is expected to be issued. The LOA delineation determined that there are four seasonal wetlands and four drainage channels on the site. Only Seasonal Wetland 4 in the western portion of the site near Alisal Street (0.45 acres) and Drainage 1 (205 linear feet) in the northern portion of the site which is a tributary to Sycamore Creek appear to be hydrologically connected other waters of the U.S. and therefore would be considered jurisdictional by USACE. The other hydrologic features appear to be isolated and therefore not considered jurisdictional by USACE, however, all the wetlands and channels of the site, whether they are isolated or not, would be considered jurisdictional by the RWQCB. For channels, the RWQCB’s jurisdiction has recently been expanded to include the bed and bank of the channel. The on-site channels would also be considered jurisdictional by CDFW to the top of the bank. The project will preserve most of the wetlands (totaling 1.28 acres) and all of the drainages (totaling 896 linear feet) occurring on the site. Slope stabilization will result in permanent impacts to Seasonal Wetland 2 (0.02 acres). This is a small wetland that is dominated by non- native wetland species such as canary grass, and which provides no additional ecological
