INFORMATIONAL MEETLNG ON KELLY’ AVENUE DR.AINAGE <br />AUGUST 18, 1994 <br />Farnham noted that Rick's Super Valu on the hill is a major contributor to runoff. The pond near <br />h'S property is a small holding pond for the amount of possible runoff Cook explained it was a <br />water quality pond which takes care of silt and sand rather than large quantities of water. Farnham <br />asked what would happen if that pond were deepened. Cook responded that the rate of runoff cannot <br />be controlled to small enough numbers to help Kelly Pond. <br />Stoddard asked for discussion about raising the road 1' or 2'. Cook replied that raising the road <br />would require digging out appro.ximately 4' and filling v%nth lightweight aggregate with a cost of <br />approximately $40,000 to raise the road 18" This would not necessarily solve the problem. There <br />is still water standing in back>’ards and ponding on the nonh side of Carman that may kill trees due <br />to standing in water. <br />Gerhardson noted that the problem keeps getting worse and is becoming more than just an <br />inconvenience. There are concerns with school bus traffic and emergency vehicles. <br />Mrs Farnham asked what would happen if Kelly Pond were deepened so it could hold more water. <br />Cook did not think it would do a lot of good because of the water table. The average lake level is <br />at 929.4 with the elevation of the road at 930.9 in this area. This is a flat area and any system may <br />have problems. Stoddard noted that if the lake sometimes gets higher than the water table it will <br />back up into this area and the road will still be under water. Cook added the total solution is to raise <br />the road and install piping. <br />Stoddard commented that deepening the slough would not make a lot of difference because the soil <br />is already saturated. In a recent survey he had done of his property, some pans of the road were at <br />930. The 100 year flood plain is at 931. He hoped the City would have some responsibility in <br />sharing the costs since the road should not be built in the flood plain. He has three main concerns: <br />1. Safety. There is a direct affect on the homeowners in the area as they have to drive <br />through water. Even though the water may be only 2" deep, others traveling the road <br />will drive onto yards to avoid the water in the road. If the water is deeper than 2", <br />it affects their vehicles and brakes. <br />2. Environmental. Traces of chemicals are left behind every time a vehicle drives <br />through the water. Since it is connected to the lake, there is a contribution to <br />pollution of Lake Minnetonka. <br />3. Cost. The residents feel the City has some responsibility. Stoddard suggested thp»* <br />may be funds available to the City from an environmental impact. He felt if the u -^u <br />were built to the 931 elevation, it would curtail many standing water problems. If <br />50-60 residents were assessed, it may only be a $40 impact per year as a tax increase. <br />Cook noted that the costs of easements were not included in projea cost estimates. <br />Hopefully there would be some property owners willing to donate easements.
