SYstponds: <br /> A facility meeting Ciry wetpond standards must be provided for both sub-basins on this <br /> project site. Calculations aren't provided for the southerly basin. <br /> The Ciry standards require a minimum of 5096 of the wetpond design volume to be <br /> provided as pertnanent dead storage and for the entire wetpond design volume to be <br /> teached for the design storm. Routmg of the design storm developed hydrograph <br /> through the pond is required to verify that the wetpond design volume is reached for <br /> the design storm. The size of the primary orifice can be decreased as necessary, to a <br /> minimum allowable orifice size of 1 mch, to back up enough live storage. If a 1 inch <br /> orifice dcesn't result in the required storage in the pond, then the percentage oi the <br /> wetpond design volume provided as dead storage must be increased until the <br /> combination of dead storage and peak live storage equals the wetpond design volume. <br /> mfsce118ueous; <br /> Additional comments are written direcUy in the submitted drainage calculation package. <br />
