53 <br /> Water Quality Requirements <br /> The project site is in the Jordan Lake basin. Water quality requirements are not enforced in this <br /> drainage basin. <br /> TMDL Requirements <br /> The project site does not discharge to any TMDL limited receiving waters. <br /> Methodology <br /> Peak Runoff Control <br /> Swales will be utilized to slow down the time of concentration for the drainage area. The swales <br /> will be built at reduced slopes then present topography to manage stormwater runoff. With the <br /> increased time of concentration,the minimally increased curve number will be mitigated as <br /> shown in the peak flow numbers modeled below. <br /> Pre- Post- Percentage Increase Over Pre- <br /> Development Development Development Conditions <br /> 1-Year 2.587 2.694 4.14% <br /> Conclusions <br /> The proposed project will meet all peak flow and water quality requirements. <br />
