Ellicott Sand& Gravel LLC Page 2 <br /> Bank Armoring Plan <br /> setback so it is close to the area where it will be placed. <br /> The attached Figure G-1 shows the cross sections of the areas <br /> discussed below and details of the armoring to protect the banks <br /> along Black Squirrel Creek and Big Spring Creek. Map Exhibit F - <br /> Reclamation Plan Map has been revised to show the location of the <br /> areas to be armored in the mine . <br /> Black Squirrel Creek Bank Armoring. <br /> Along the inside of Black Squirrel Creek and Big Springs Creek <br /> banks armoring will be placed where ever mining will take place <br /> within 400 feet of the bank. The armoring will be done as mining <br /> advances in stages so that nor more the 500 feet needs to be done <br /> a any-one-time . As mining approaches the 400 foot limit the <br /> channel adjacent to mining area will be armored following the <br /> UDFCD Guidelines . Bank armoring will be done using the asphalt <br /> and concrete recycle material described above using the D50 <br /> material size specification. The armored face of the bank will <br /> extend to 5 feet below the thalweg of the dry channel to the top <br /> of the existing bank and will be a minimum of 2 feet thick. This <br /> will leave an armored face along the surface that is 29 feet <br /> wide . On average this will require 2 . 77 cu-yds per linear foot . <br /> The armoring will not take place in the OHW but rather along the <br /> historic bank of the creeks . The face of the armoring will be <br /> sloped 2 . 5h to lv per the guidelines . <br /> Excavation Bank Armorincr. <br /> On the inside of the mined area adjacent to the creek channels <br /> the armoring will be placed from the existing elevation so the <br /> toe of the armoring will be a minimum of 3 feet below the creek <br /> thalweg and will be 2 feet or more thick. This is approximately <br /> 1 . 64 cyd/lft along the excavation bank slopes . The armoring will <br /> cover the bank slopes from the original ground surface to a depth <br /> of 3 feet below the channel thalweg and parallel to the channel . <br /> Once sloping begins the armoring will be installed on 500 foot <br /> sections until completed. This will leave an armored face along <br /> the surface that is 27 feet wide . <br /> Supplied supporting documents <br /> Figure 1 - Bank Protection Plan cross section <br />
