Mounds View City Council April 9, 2001 Regular Meeting Page 8 Director Ericson explained it is an issue of the wetland credits and not of actually directing the water to that pond. Mayor Sonterre asked if residents wanted to improve streets with curb and gutter how it would work with the new needs for a place to send the water. The Rice Creek Watershed representative explained it is the standard policy of the district to require ponding if streets are reconstructed. The representative then noted the pond would factor positively into the equation but would not speculate as to whether it would mean absolutely no ponding or a lesser amount. Council Member Thomas asked what moving the pond to the north side of Highway 10 would do to the effectiveness percentage. The Rice Creek Watershed District representative indicated it would be fairly significant because the area to the west does not drain through the golf course. Council Member Marty stated he had a number of comments from residents on the south side of Highway 10 who indicated they would like to preserve their area as much as possible. He then questioned whether a smaller pond in the proposed location in conjunction with some ponding on the north side of Highway 10 would be workable for Rice Creek Watershed. The Rice Creek Watershed District representative stated they needed to make those decisions independently due to the planning and budgeting cycle. The representative then noted that if Council desired to stay with a smaller pond they will move forward this planning and budgeting cycle and look at the possibility of doing something additional on the golf course during another budget cycle. Council Member Thomas stated she had gone to the proposed ponding area to view it. She then asked residents in attendance to explain the difference in the current water level as compared to a normal water level. Mr. Lamb of 2305 Sherwood Road stated that normally after the ground is thawed there is about one foot of water in JD1 and Junction 5 almost never has any water in it. Mike Reed of 2208 Lois Drive stated he believes the water appears to be coming out of Highway 10 rather than Sherwood Road. He then stated he did not believe that 60% of the flow is coming off of Sherwood Road. The Rice Creek Watershed District representative indicated the feasibility study gives a proposal for a 12, 9, 6, and 3 acre pond and gives decreases in flow rates of roughly 30 to 35%. He then noted the two things to keep in mind with flow numbers are there are two branches. One branch from the north and one branch from the west. He then explained the water flows a lot more slowly out of the north than from the west. He further explained they are concerned with the erosion that takes place with the sudden large flows from heavy rains and snow melts.
