The apparatus is constructed to prevent erosion of soil during typical weather or tidal conditions and adverse weather events. The apparatus can include a plurality of anchored rolls and soil lifts operative to stabilize the shoreline. ## Claims ### Claim 1 An erosion control apparatus comprising: a plurality of fiber rolls, wherein the fiber rolls are arranged relative to a slope adjacent to a shoreline; a plurality of anchors, each anchor comprising a cable, each cable extending from one or more fiber rolls to a depth into the slope, a most seaward anchor inserted at a deeper depth than other anchors of the plurality of anchors; a connecting cable harnessing together the plurality of fiber rolls; and a fill material positioned between the fiber rolls and the anchor points, at least a portion of the plurality of fiber rolls and the fill material being positioned over the anchor points. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein each cable extends from inside a fiber roll. ### Claim 3 (depends on 1) The apparatus of claim 1, further comprising a plurality of crimps, each crimp securing a cable to a fiber roll. ### Claim 4 (depends on 3) The apparatus of claim 3, wherein each crimp forms a loop in a cable. ### Claim 5 (depends on 4) The apparatus of claim 4, wherein each loop is welded at a point below a fiber roll. ### Claim 6 (depends on 1) The apparatus of claim 1, the anchors being spaced at intervals across each fiber roll, each interval having a length in a range of 24 inches to 96 inches. ### Claim 7 (depends on 1) The apparatus of claim 1, wherein the anchors are inserted at a depth of at least 42 inches below a slope surface of the apparatus. ### Claim 8 (depends on 1) The apparatus of claim 1, wherein each anchor provides between at least 2,500 to 6,500 pounds of holding force through the cable. ### Claim 9 (depends on 1) The apparatus of claim 1, further comprising a first trench located at a highest end of the apparatus; the trench being backfilled, wherein the first trench is at least 6 inches wide and at least 6 inches deep. ### Claim 10 (depends on 9) The apparatus of claim 9, wherein the trench is covered with sand or soil. ### Claim 11 (depends on 1) The apparatus of claim 1, further comprising plant material positioned on or within at least one fiber roll. ### Claim 12 (depends on 1) The apparatus of claim 1, further comprising a mesh that covers at least one of the fiber rolls. ### Claim 13 (depends on 1) The apparatus of claim 1, further comprising at least one erosion control blanket, wherein the blanket comprises a biodegradable material. ### Claim 14 (depends on 1) The apparatus of claim 1, further comprising a marsh installation placed seaward of a first fiber roll of the apparatus relative to the shoreline, wherein the marsh installation comprises a plurality of cobblestones wrapped in coir fiber. ### Claim 15 (depends on 1) The apparatus of claim 1, wherein the fill material comprises a soil lift coupled to at least one fiber roll. ### Claim 16 (depends on 15) The apparatus of claim 15, wherein the soil lift comprises at least one layer of coir fabric that retains sediment. ### Claim 17 (depends on 1) The apparatus of claim 1, wherein each anchor includes a duckbill anchor or a helical anchor. ### Claim 18 (depends on 16) The apparatus of claim 16, wherein the most seaward anchor is a helical anchor. ### Claim 19 (depends on 1) The apparatus of claim 1, wherein each cable is coupled to a plurality of rolls. ### Claim 20 A method of installing an erosion control apparatus comprising: arranging a plurality of fiber rolls relative to a plurality of anchors; connecting the plurality of anchors to the plurality of fiber rolls with one or more cables and a connecting cable harnessing together the plurality of fiber rolls, the anchors positioned at a depth, a most seaward anchor positioned at a deeper depth than the other anchors of the plurality of anchors, wherein each cable passes through a fill material. ### Claim 21 (depends on 20) The method of claim 20, wherein each anchor point is placed in position before the fiber rolls are positioned. ### Claim 22 (depends on 20) The method of claim 20, further comprising securing a plurality of crimps, each crimp securing a cable to a fiber roll. ### Claim 23 (depends on 22) The method of claim 22, wherein each crimp forms a loop in a cable. ### Claim 24 (depends on 23) The method of claim 23, wherein each loop is welded at a point blow a fiber roll. ### Claim 25 (depends on 20) The method of claim 20, further comprising inserting the plurality of anchors at at an interval, each interval can have a length in a range of 24 inches to 96 inches. ### Claim 26 (depends on 25) The method of claim 25, further comprising inserting the anchors at a depth of at least 42 inches below a slope surface of the apparatus. ### Claim 26 (depends on 20) The method of claim 20, wherein each anchor provides between at least 2,500 to 6,500 pounds of holding force through the cable. ### Claim 27 (depends on 20) The method of claim 20, further comprising installing a soil lift comprising at least one layer of coir fabric. ### Claim 28 (depends on 20) The method of claim 20, further comprising installing a marsh installation seaward of a first fiber roll of the apparatus relative to the shoreline, wherein the marsh installation comprises a plurality of cobblestones wrapped in coir fiber.
