We are submitting these for your review and approval <br /> for construction. <br /> From the calculations, the channel has been designed for a flow of <br /> 51 CFS, which would have a velocity of 1.9 feet per second, not ex- <br /> cessive in a grass lined cF;annel . <br /> We re�lize that under the unusual conditions when the channel would be <br /> passing the design flav, the lcw area around the overflav channel en- <br /> trance would be inundated to elevation 610.3, in order to build up the <br /> tv;o foot depth of flow, but ex;,ept for the channel construction, the <br /> �emainder of this area wil� remain in its natural state. <br /> If you have any questions or comnents, please call me. <br /> Sincerely, <br /> .���,..,�>�L-.�.,µ �. <br /> Steven Mennet, P.E. <br /> Civil Engineering Division <br /> SWM/mie <br /> cc: Clay Bush - Fluke Mfg.
