1 1 1 COUNCIL MEETING January 12, 1987 Page Seven now, will it be the same after development? Mr. Stahlberg said yes, this is a requirement of RCWD. Mr. Nelson said the lake cannot take anymore damage from fertilizers and sewage. The lake area residents treat the lake for weeds at their own expense now. He asked, can you assure me that the runoff will be the same quality as it is now? Mr. Newmeister said RCWD will require controlled flow and the installation of a skimming de- vice and control of erosion and sediment. Mr. Nelson said his con- cerns regarding water quality in the lake would be alleviated if a water quality test were performed after the construction is com- pleted. He did not want additional development to add to the con- cerns of the residents already there. Glenn Bowen - 6873 Black Duck Drive asked what type of filtration system will be used on the wier? Mr. Newmeister said this informa- tion will be supplied later but will conform to the requirements of the RCWD. Mr. Bowen was concerned that runoff to the lake may con- tain soap, street oil etc. He wanted to be sure that the runoff is controlled so that the quality of the water entering the lake is at least as good as it is now. Gary Bailey - 6940 West Shadow Lake Drive was concerned because the runoff from this plat could increase the lake level. He said the Council could balance this by getting water out of the City. Mr. Stahlberg explained the runoff into the lake will stay the same as it is. now. It will be controlled so no peaks will be created. Mr. Bailey said he was concerned because the plat may route water north where normally it would flow south. Mr. Stahlberg explained that the southern portion of the plat is the highest point so the water normally flows north. He also noted the City is preparing to adopt a master storm water drainage plan that will address all of the storm water problems. 089 Ron Conway - asked if the Council was going to complete the storm water manage master plan before they adopted this plat. Ur. Stahl - berg explained there is much to do before the plan is prepared and will take some time. Mr. Conway asked how snow thaw would be con- trolled. Mr. Stahlberg explained that the snow would melt, run in the street to a catch basin which would be piped into a holding pond and then be handled the same as storm water. The catch basins must be kept thawed by the Public Works Department. Tom Drow - 6317 Red Maple Lane said his back yard never dries up and told the Council that the area needs to get rid of the existing standing water. He was concerned about what will happen to the drain- age in the northeast corner of Colonial Woods plat. Mr. Newmeister said a swale will be constructed to take the drainage northward. Mr. Drow said he wanted some sort of insurance plan because the best in- tentions do not always happen.
