'Che purpose of these site � isits would be to evaluate <br />the bioengineering [eatures and vegetation, and determine whether additional plantings were <br />n��cessary. A brief lelter report would be submitted to the C� ; of Everett following each of <br />the fall monitoring efforts• The projected level of effort is approximatel,v one ro lwo work <br />days per monitorirg period. The mor.itoring schedule is presented in Table 3. <br />PERFORMANCE STANDARDS <br />Performance sWndards are proposed for the bioengineering elements of the pro;ect to <br />increase confidence in the stability of the design. Performance standards vary by the type of <br />soil bicengineering solution selected. The following inEormation outlines the performance <br />standard 'ny installation type. <br />LIVE FASCINES <br />A minimum oF 25 pereent of the individual cuttings must sprout within each individual <br />fascine during the first spring after installation. Meeting this standa�d would provide <br />confidence that sufficient root development would acur to provide long-term bank stability. <br />During the fall of the second year, 25 percent of the cuttings must still be alive in each <br />fascine. Averaging survival among fascines is not permissible. <br />LIVE STAKES <br />�a <br />, k� In those areas whete live stakes are intended to provide bank stability, 75 percent <br />� survival at the densities outlined in the p1an5 is required at the end of the second year. <br />�� Initial installetion dersities will exceed the plan densities; therefore, the presence of small <br />scale mortality would ti�ot likely cause a failure of the performance standard. <br />�� <br />ir <br />�Y <br />M� <br />16 <br />w <br />e,��_.�y F�_ ':».sae�i� <br />6GL � <br />
