_USDA united states Natural Resources Conservation Service <br /> �--•� Department of <br /> Agriculture <br /> Operation &Maintenance Plan <br /> Streambank and Shoreline Protection (Code 580) <br /> Landowner/Operator: Will Good Date: 6/23/2022 <br /> NRCS Service Center: Macon Conservation District: Macon <br /> Practice Location: T1 6N R3E Sec 16 Tract/Field ID:N/A <br /> (Lat/Long or LITM Coord,or SecITS/R) <br /> Expected Lifespan <br /> The minimum expected lifespan of this practice is at least 20 years. <br /> Follow the operation and maintenance plan below to keep your streambank stabilization measures <br /> functioning as intended: <br /> • Inspect treated areas and associated practices annually,after significant storm events,and after <br /> Ice flow to identify repair and maintenance needs. <br /> • Check all rock riprap sections for accelerated weathering and displacement. Replace to original <br /> grades if necessary. Some movement of smaller stone and sorting of material is expected. <br /> • If any crest stones(large rocks used to form the center ridge of a rock riffle or stream barb)are <br /> displaced,the structure should be repaired immediately. <br /> • Periodically inspect the bank area above the rock keys. If any settlement or displacement of the <br /> earth fill is observed,the settled area should be promptly refilled and compacted to prevent the <br /> formation of a surface flow channel that would erode the supporting bank material. <br /> • All settlement or cracks in the soil should be investigated to determine the cause and immediately <br /> repaired. <br /> • Remove any debris that accumulates at the protected section,and immediately upstream or <br /> downstream from the installed structures. <br /> • In cases where the bank is left in a near vertical position,expect continued bank failure until a <br /> stable slope is reached. <br /> • Natural regeneration of native vegetation including woody plants should be left intact to improve <br /> bank stability and wildlife habitat. <br /> • If fences are installed,they shall be maintained to prevent unauthorized human or livestock entry. <br /> • Control livestock access on unfenced areas. <br /> • Keep machinery away from steep side slopes.Keep equipment operators informed of all potential <br /> hazards. <br /> • Immediately repair any vandalism,vehicular,or livestock damage. <br /> NRCS, IL O&M-Page 1 of 2 February 2012 <br />
