i CONTINUED APRIL MEETING OF THE LOWER RUM RIVER APRIL 16, 1993 CALL TO ORDER Chairman Jim Schrantz called the meeting to order at 8:30 a.m. in the Committee Room of Anoka City Ball. ROLL CALL Members present were Jim Schrantz, Steve Jankowski, and John Weaver. Ben Ferguson was absent. PENDING PROJECTS/PERMIT REVIEWS Amber Ridge (Continued from April 15, 1993 meeting) Jankowski provided an update of the proposed Amber .Ridge project. He indicated the initially proposed drainage plan, stating that now the developer proposes to pull out some of the catch basins and put others in the street to the north, allowing most of the drainage to flow away from the Rum River and into a detention basin, leaving only the area nearest the Rum River to put its drainage into the Rum. Approximately 16,000 square feet of impervious area, or half of the street, will now not discharge into the Rum River. The drainage going into the Rum River would consist of the street plus 3,000 square feet from each of the six lots. Jankowski went on to discuss in some detail how the drainage would then be proposed for the area by taking the catch basins out just north of the Rum River-drained area and put them further to the northwest. He felt the back yards of those northwest lots would be high enough to handle this runoff. Jankowski went on to state that the wetland to the northwest is a dry socket. There are a series of three wetlands in which to catch the drainage. He also indicated there is an emergency overflow should there be an unusual storm event. The discharge from ponds would back up and start discharging into the Rum River. Jankowski was of the opinion that overall it is a pretty responsible drainage plan. Weaver queried. why Jankowski did not want this development plan reviewed by the LRRWMO Consulting Engineer. Jankowski stated there is no particular reason other than the time factor and cost.
