We <br />understand the project includes a commercial development area of approximately 1.51 acres <br />and a residential development area of approximately 2.52 acres. We have determined from <br />the City of Paris drainage plan that the 10 year flow for this waterway is approximately 490 <br />cubic feet per second. The estimated impact is as follows: <br />Commercial Area: <br />10 year frequency runoff undeveloped = 2.6 c.f s. <br />10 year frequency runoff developed = 5.6 c -fs. <br />% increase in waterway flow . = 0.6% <br />Residential Area: <br />10 year frequency runoff undeveloped = 4.3 c.fs. <br />10 year frequency runoff developed = 7.4 c.fs. <br />% increase in waterway flow = 0.6% <br />If you have any questions or need additional information, please contact me at (903) <br />784 -6393. <br />Sincerely, <br />Chaney Engineering, Inc. i• <br />R.
