<br />CHAPTER III <br /> <br />~AS:fER_I1-~_lll<p.",}~g~; <br /> <br />In_~!~q~~c~.i?_~. <br /> <br />All drawings referred to in this re)ort are presented in Volume II c <br /> <br />The base maps for drawings numbered 1 through L~ are taken from the Phase <br /> <br /> <br />A report. They depict the drawings list, tocation of the First Creek <br /> <br /> <br />basin, index maps, plan and profile legelld, and basin and sub-basil) <br /> <br />boundaries. <br /> <br />Drawings 5 through 8 show the 100-year design hydrographsc These <br /> <br /> <br />hydr'graphs represent flows at selected design points within the drain- <br /> <br /> <br />age basinc The peak flows from these hydrographs were presented in <br /> <br />Tabl e II -4 c <br /> <br />Drawings 9 through 32 present the docainage"ay planning for First <br /> <br /> <br />Creek in the form of plan and profile sheetsc These drawings show the <br /> <br /> <br />proposed drainageway improvements and the future 100-year flood plain <br /> <br /> <br />corr',sponding to the improved drainageway. Also, the future lOCi-year <br /> <br /> <br />floolj plain corresponding to the exist.inl~ drainageway conditions is pre- <br /> <br /> <br />sentl~d for reaches where structural improvements are not recommendf~d, <br /> <br />The major drainageway plannj.og drawl.ngs COIltain sufficient detail <br /> <br /> <br />III both plan and profi 1e for planning purpo:3es _ Therefore, the follow.- <br /> <br /> <br />ing discussion will not contain any speci tics foy individual improve" <br /> <br /> <br />mentl;.

As soon as it is practically possible, the area within <br /> <br /> <br />the 100-year flood plain for future basin development and existing <br /> <br /> <br />drainageway conditions should be desigTled as Flood Plain Zone. <br /> <br />2. At such time in the future, \vhen the drainageway improve- <br /> <br /> <br />ments suggested in this report are imp_emented, the Flood Plain <br /> <br />zoned areas as in 1 above should be moclificd to cover areas under <br /> <br /> <br />the future 100-year flood with imprcv~d dr.inageway conditionsc <br /> <br />IlJ-l <br />
