Deternunation of capacity of proposed conduits, bridges, reservoirs, BMP <br />facilities, channel levees, etc. <br />c. Estimation of the damage reductions. Provide flood damage cost <br />calculations of damage potential for the future watershed condition for the <br />�-, 10-, 2�- and 100-year return periods. <br />d. Deternunation of required right-of-way. <br />e. Relationship of the cost of each alternate to the direct and indirect <br />benefits. <br />£ Consulta.tion and decision on legal matters (provided by COiTNTY). <br />g. Production of worlang map(s) showing the extent of flooding for each of <br />the best alternate plans as defined in 2.A.6. for future watershed condition <br />for �-, 10-,2�- and 100-yeaz return periods. <br />h. Typical cross section of each reach for the best alternates. <br />2.A.8. Consideration shall be given by ENGINEER to current Federal <br />Emergency Management Agency floodplain management policy. <br />2.A.9. ENGINEER shall consider the operation and maintenance aspects of the <br />best altemate plans as defined in 2.A.6., relative ta <br />a. Erosion control <br />b. Cleaning and removal of debris and sediments <br />c. Repair of structures <br />d. Re-seeding and planting of grassed azeas <br />e. Bank stabilization <br />f. Riprap <br />g. Access to entire length of Drainageway <br />2.A.10. ENGINEER shall become cognizant of the soil characteristics of the � <br />watershed(s) and will obta.in available NRCS soil info:znation. If ENGINEER <br />feels soil samples are necessary to determine feasibility of any alternate, he shall <br />so recommend to COLJNTY. Detailed soil analysis, if judged by COUNTY as <br />needed, will be provided by COUNTY. <br />2.A.11. ENGINEER shall consider the unpact of each alternate on water quality <br />in the watershed(s), and the adapta.bility of each altemate to provide possible <br />future storm water quality enhancement measures. The work shall be lunited to <br />
