PW CASE.~ <br /> <br />CONSIDER ALTERNATIVE OUTLETS FROM <br />REGIONAL POND IN BUSINESS PARK 95 <br /> By: Steven J. Jankowski, City Engineer <br /> <br />Background: <br /> <br />The area south ofCR 116, east of CR 57, and north of the railroad tracks was developed as an <br />industrial area beginning in 1995 and has becomes known as Business Park 95 and its <br />subsequent additions. Although there are a number of drainage areas within the Park, the largest <br />is located at the extreme southeast comer next to the City of Anoka. Although there is <br />significant ponding capacity, there presently is no positive outlet from this watershed. <br /> <br />With the addition of Mississippi Sub District No. 1 flowing to this regional pond, an opportunity <br />was created to establish a positive outlet for this system, by installing 476 of 24 inch pipe to <br />connect this ponding system to the 42 inch storm sewer on the west side at Sunfish Lake <br />Boulevard. <br /> <br />Recently it was suggested that an overflow to the City of Anoka's storm water system in their <br />Business Enterprise Park may be a more economical alternative. The Business Enterprise Park <br />has a large outfall pipe to the Mississippi River. <br /> <br />Staff has prepared cost estimates for both these alternatives. The attached evaluations are limited <br />to only the costs associated with making the physical connection for each overflow alternative. <br />At this point there has been no formal discussions between Ramsey and Anoka, however, the <br />City of Anoka does have past practice of charging for the right to discharge into their storm <br />sewer system. <br /> <br />The results of this analysis show the cost of discharging into Anoka's system to be 54,409 while <br />the cost of discharging into the Sunfish Lake storm sewer is $48,320. It is also important to note <br />that the Mississippi Sub Drainage District No. 1 has been credited $102,500 for this overflow. <br /> <br />Recommendation: <br /> <br />It is Staff recommendation that the storm sewer overflow connection to Sunfish Lake Boulevard <br />continue to be preserved. <br /> <br />Action: <br /> <br />No action is necessary, unless a change in policy is desired. <br /> <br />Reviewed by: <br />Public Works Director/Fire Chief <br />Principal City Engineer <br /> <br />PW: 05/20/03 <br /> <br /> <br />
