Mounds View City Council Page Fifteen. ~egular Meeting September 13, 1993 ponding water. If the City wants to size the storm sewer and street improvements to the recommended standards of today, a storm sewer system would have to be put in Sherwood Road. Ms. Werner stated that she knows there are problems on Knollwood Drive because that area is swampy. Rocky Keene stated that the water from Sherwood is adding to the problem on Ardan Avenue. The Sherwood system must be made an independent system which would help Ardan Avenue residents. Councilmember Blanchard asked Rocky Keene to differentiate between the soils of residential and commercial areas. Mr. Keene explained that the community of Mounds View is based on two different soil types -- sand and loam soil. A big portion of the sandy soil runs down Highway 10 and the business and industrial areas have less of a runoff than the loam soils. A lot of communities do not go through the exercise of weighting the runoff. Mayor Linke stated that Scenario ~i is based on those having the most runoff and Scenario #2 has the commercial and business properties as which having less runoff potential. • Roger Stigney asked if rather than redoing the sewer line, has there been some consideration of tying into that line. Mr. Keene stated that the best way was to run a parallel line to Ardan Avenue and it could be tied into any street improvement project. This is amore cost effective system. Most cities tend to improve the storm sewer at the time they feel they need a street improvement. The curb and gutter type system lasts longer. Long Lake Road would go in and if oversizing has to be done, Long. Lake Road would not have to be done in five or ten years. Roger Stigney asked if it were allocated for 1994 or 1995 to put that storm sewer in. Mayor Linke stated that this project is listed in the Long Term Financial Plan, but if there is a need elsewhere and not a need in this area, it will not be done at that time. Councilmember Trude stated that some cities are giving credits to those businesses who have planned for the runoff from their properties. Mr. Keene stated that the credit plan that is most successful is to have a review of individuals who wish to apply for a credit. The individual can work with City staff and come up with a recommendation to the Council as to why they should have a credit. There are many scenarios that could come up for credits. Individuals would have to come in and prove that they are not contributing to the system.
