Table 1. Continued agencies during the permitting process. BIO-2a. Disturbance of the existing freshwater marsh shall be avoided DPW to the greatest extent possible. Where complete avoidance is not feasible, the following mitigation measure(s) shall be implemented. BIO-2b. Temporary orange barrier fencing shall be installed around DPW areas of freshwater marsh to establish a buffer zone around the edge of the marsh habitat at a distance to be determined in cooperation with the Corps and the City. This installation shall be performed by a qualified biologist prior to construction and all construction activities shall be restricted to the outside of the fenced-offareas. Fences shall remain in place throughout the construction period and shall periodically be inspected to ensure that they remain in place. BIO2c. In those areas of freshwater marsh that cannot be avoided DPW during construction activities, new plantings shall be installed once construction is finished. The new planting shall be of the same species removed during construction to ensure a "no net loss" of habitat functions and values. Plantings shall be monitored for a minimum of 5 years to ensure survival and to ensure that the plantings meet performance criteria to be established by the regulatory agencies during the permitting process. If these performance standards are not met, remedial actions shall be taken. Ifonsite replacement is not feasible due to the placement of the new bridge structure, the following mitigation measure shall be implemented. BIO-2d. To compensate for the permanent loss of freshwater marsh DPW habitat within the construction area, the City shall prepare an offsite planting plan, which will be subject to approval by the Corps, as part of the Sections 404 and 401 of the CWA Offsite plantings shall be placed at a suitable site owned and maintained by the City. Plantings at the offsite locations will be subject to the same performance criteria as onsite plantings. Planting ratios and performance standards shall be established by the regulatory agencies during the permitting process. BIO-3 Prior to the initial site investigation and subsequent ground disturbing activities, a qualified biologist will instruct all project personnel in worker awareness training including recognition .of California red-legged frogs and their habitat.
