The <br />revised data was sent to Short-Elliott-Ilendrickson for review. <br />Attached is the Short-Elliott-liendri.ckson response. <br />In summary, the changes are as follows: <br />Initial Proposal Revised Proposal <br />Pond Storage 50 AC -FT 40.5 AC -FT <br />r-. <br />Discharge Rate 15 CFS 12.5 CFS <br />Drainage Rate 266 Acres 203 Acres <br />Peak discharge rate before development was 64 cubic feet per <br />second (CFS). The pond therefore meets or exceeds the require- <br />ments of Resolution No. 983. <br />The Short-Elliott-Iiendrickson report also comments on the follow- <br />ing items: <br />1) Pond storage will be needed for property east of Long <br />Lake Road <br />2) Future flow under Long Lake Road will have to be <br />restricted to approximately 3 CFS with approximately <br />9 AC -FT of storage. <br />3) Flow downstream through 27 inch RCP from Ri�ge Lane <br />to Rice Creek is improved but not completely resolved. <br />Therefore, it is recommended that the City Council approve the <br />modified Oak Lake Pond. <br />JCJ/bc <br />Attachment <br />n <br />
