For <br />establishing the "Top of Levees" for the select.ed project <br />design. a three foot freeboard was added to the 100-year water <br />surface elevations with a selecteel FEMA floodl.ay. The <br />influence of a levee system is comparable to the influence of <br />FEMA selected floodway; therefore. the floodway water surface <br />elevations are accept.able estimates for the design of the <br />Town's levee systems. These water surface elevations are shown <br />on plates 2 and 3. <br /> <br />7.0 Plan Formulatio~ <br /> <br />The flood mitigation measures which were considered in the <br />formulation of a flood control plan include a flood control <br />levee system; flood insurance coverage; and floodproofing of <br />st.ructures.
