1 I 1 Council Meeting Minutes April 28, 1992 Page 5 Council Business. continued Harold Peterson, Church Engineer, worked with staff to design a plan which limits the. amount of water running to the east, The church is aware of the p(oblem$ and desires to install an addition which has the least effect on neighbors. The northeast pond would release the stormwater to the east at a rate of 1.2 CFS compared to a current 11.5 CFS. Williams said the present pond appears unkept. and asked if the ponds will lie treated 'wi,th 8 liner or landscaped with rocks. Peterson said the new pond will be constructed of clay material and landscaped on the sides. Bill Flor, 830 Oakwood Drive, said many times in the past 30 years, water has come up through his basement floor and at one time the water was two leet deep. He feels the pond's landscape plan is not attractive. Rose 'Kozel, 810 Oakwood. feels a ditch area at Oakwood and 7th Street w~uld cause a safety risk to the schoolchildren. Bob- Kozel, 810 Oakwood, has seen constant water problems for 26 years. He ,quoted Army Representative Steve Macke. who said the Army forcem8in may not be abandoned. it is not a "done deal" and may take longer than 1994. He has seen the pond overflow with more water than Council is led to believe, The proposed pond would drain into his storm sewer, and when the sewer is closed the water would overflow into his yard. The original system was designed for the homes. not the church. and a 7th Street storm sewer is needed before the proposal is approved. Mr. Peterson never witnessed the pond overflow, but if a rainfall overloaded the system, an emergency feature saves damage to buildings. Runoff will not leave the site before going through the retention pond. Reb~lein asked what would happen if an 100 year rainfall occurred. Mr. Peterson said there is additional storage over and above an 100 year rainfall in the parking lot. However, he cannot guarantee there would not be a rainfall that 'could overload the system. The retention pond will be graded 12 feet higher than the adjoining properties. Williams feels the residents deserve a more creative landscape plan than the one proposed. Mr. Peterson said changes will be made to the plan, Mattila said staff and the residents will review the landscape plans. Williams asked if the pond overflowed. could runoff be redirected away from a drain that is already full. Mr. Peterson said the church will take the runoff and channel it away from the backyards. Williams said in anticipation of a new pipe on 7th Street. could a pipe also run from the eastern pond into the street. Mr. Peterson said with the site elevation, the only option is a lift station which could have costly maintenance problems. Mr. Kozel said the church will spend money to install pipes to drain the parking lot underground. but dumps their runoff onto public roads. These improvements are temporary solutions to the major issue of installing a storm sewer. He feels the pond material should be concrete, not clay.
