INFORMATIONAL xMEETING ON KELLY AVENUE DRAINAGE AUGUST 18,1994 Scott commented that Option D would have a major impact on trees that would have to be removed. It would take years to replace that growth. Stoddard asked about raising the road to see how that works and then look at a drainage system. He felt raising the road 2' would have minimal impact on the neighboring properties and would take care of the majority of the problems. Gerhardson felt there would have to be something done in addition to raising the road. The pipe along Famhams ’ property is only 8" while the pipe under Kelly .A.venue at the pond area is a 12" pipe. As it goes under the ne.xt driveway, an 18" pipe is used and then runs into an 8" pipe as it goes under Carman Road. This restrirtion slows drainage down. The same size pipe throughout the system would be desirable. Farnham asked about the possibility of an additional pond at the Kelly Avenue comer. Cook questioned if it would actually help with flooding problems. He added that from a water quality point of view, the current system is good. Gerhardson stated that by just raising the road, every culvert would have to be open and working to capacity to be effective. Farnham noted that at one time an option was considered to run a storm sewer along the sanitary sewer lines to County Road 19 Cook stated it would have to be pumped up to get through the Old Beach Road area which would be difficult and costly. Mrs Mitchell thought the road had settled and there was less water in the slough than in the past. Gerhardson felt the growth over the years may make it appear that way. Mrs. Farnham asked what would happen to Carman Cove if the pipes were increased in size and there was more drainage. She stated there were already a lot of weeds in Carman Cove. Mr. Farnham thought increased water would only lead to more weeds. Cook agreed. Stoddard reiterated that raising the road with a culvert underneath it seemed the most economical route. Cook stated the City has many concerns and would have to be prepared to do the en^e project if raising the road did not solve the problem. Stoddard asked if the City has an obhgation to build the road at or above the flood plain of Lake Minnetonka. Cook thought the road was probably built at the 932 elevation but the road has settled. Mrs. MitcheU asked why there were no problems with the road that goes through the slough. Gerhardson responded the road construction was different on Kelly Avenue. Gerhardson stated that the size of the pipe along Famham ’s house was a major concern. If there any changes in drainage, it would be imperative that water could run out of it.were
