MINUTES OF THE ORONO PLANNING COMMISSION MEETING HELD ON SEPTEMBER 18, 1.995 • ( #5 - #2059 Minnehaha Creek Watershed District - Continued) Peterson inquired about long term maintenance. LaBounty said this would be done thru agreements. Long Lake has already entered into an agreement regarding a fish barrier. If no agreement is made with Medina or Orono, the MCWD would handle the maintenance. Lindquist asked how often cleaning out of the sediment would occur. Syverson said this is site specific and depends on facts such as erosion and development, which would increase the amount of cleaning done. Syverson said the Orono project is two cell. The first cell would catch the most sediment and need to be cleaned out in 3 -5 years. The larger cell would require less frequent cleaning projected at 15 -20 years. The maintenance is dependent upon the management practices upstream. Hwy 12 construction was cited as an example. If silt fencing were not done on the ponds there, more material would fall into the ponds requiring frequent cleaning. Syverson said the management is a cooperative effort. Lindquist inquired about the Dickey Lake area. Syverson noted this was a very small phosphorus loading area and the cost would not justify a pond. It was noted that the wetland area on the east end of Long Lake where there are streams works as a detention pond. This area was noted to serve as a natural stormwater management pond as the • water comes out of this area quite clean. Schroeder inquired about runoff from roads such as Hwy 12. LaBounty said this does exist but they try to make up for it with projects such as the pond. Peterson asked for public comments. Bill Pearce, joint owner of the subject property, along with his attorney, Greg Fontaine of the Dorsey firm were in attendance and asked to present a summary of the conditions of the settlement agreement between Pearce and the MCWD. Fontaine said Pearce became involved when the plans for the pond were announced. The original proposal was for a 3- cell, 5 acre pond south of 6, not Deerhill in Medina, with small ponds in Long Lake. Pearce then retained an engineering firm to come up with a better solution. The size of the detention system on the Pearce property was then reduced which was a substantial improvement. Pearce said he understood the need for the detention pond on his property, although he would prefer it was not necessary, and was generally supportive, and still is, of the project. Fontaine said there have been design specifications and significant alterations made without consultation with Pearce. He cited an example with changes to the fish barrier upstream from Long Lake. LaBounty later noted the net effect of the change in the barrier would not affect the outcome. 13
