It is recommended that SCC avoid creating convex <br />topographic features within channel reconstruction azeas. Long-term erosion could result <br />in enforcement actions and/or delays in bond release. <br />12. Response accepted; however, the Division cautions that proper filter layer installation is <br />important to riprap channel function. If used, fabrics must be properly keyed to avoid <br />undermining of the installation. Additionally, the fabric and entire channel cross section <br />must be covered with the appropriate rock thickness, with no gaps in the rock along the <br />channel. Use of a gravel filter layer may prove more effective than use of filter fabrics at <br />the channel reconstruction azeas. <br />If you have any questions please contact me. <br />Sincerely, <br />~~~ <br />Michael P.
