This area will now be rip-rapped <br />to avoid future erosion problems. <br />Since the ditch from this point on downstream is at a rather low <br />decline, equipment (back-hoe) will be moved in to steepen such <br />angle preventing deposits of material right below the culvert. <br />Contractor will mobilize the proper equipment on November 23 and <br />the repair and modification should be completed by November 24, <br />1987. <br />Sincerely, <br />~ ~~~~~~ <br />E.
