TO: Honorable Mayor & City Council Members <br />FROM: Kim Stephan <br />DATE: July 8, 2010 <br />SUBJECT: Consideration of including Hidden Spring Park as part of the Storm Water <br />Reclamation Project <br />The following excerpt is from the July 7, 2010 Parks & Recreation Committee Meeting Minutes regarding <br />the Storm Water Reclamation Project Update from Mr. Mark Statz, City Engineer. <br />Mr. Statz reported to the committee that the Storm Water Reclamation Project is moving forward using <br />the storm water pond located in the Anoka County Regional Park located at the end of LaMotte Drive. <br />The pond is not currently designed to take as much water as will be directed into it, but changing <br />inlet/outlet structures and adding the Storm Water Reclamation System will meet the requirements of <br />volume control designated by Rice Creek Watershed District. The pond will not need to be made bigger <br />or deeper. The City has received a grant which will fund a portion of this project. The irrigation system <br />is being designed with many variables in mind. It will be a system typical of those used on golf courses <br />using a minimal number of large heads to sprinkle wide areas. There will be a pump station at the pond <br />with a forced main feeding the irrigation system. The entire park will be irrigated. Drain tile will also be <br />installed which was a concern to the committee as complaints are frequently received regarding the fields <br />being too wet. The drain tile discharge will be put in the south west comer of the park to the pond which <br />is often dry. The construction will affect any fall sports that may use the park during this time such as <br />football and soccer. The question may arise from residents as to whether the fields are being re- graded <br />during this project and Mr. Statz said they will not as this would be too costly. <br />Committee Member Seeley questioned whether Mr. Statz was aware of the committee's plans for a volley <br />ball court and how this project may affect the area intended for the court. Mr. Statz was not aware of the <br />project. Ms. Stephan will send the City Engineer the preliminary plans and intended location of the sand <br />volley ball court so this can be taken into consideration with the design of the irrigation system. Mr. Statz <br />reported the gravel drive way from Centerville Road will be removed. Committee Member Haiden said a <br />portion of this was intended to be used for a parking lot for the volley ball court. <br />Mr. Statz reported City Council had directed Bonestroo to test soil in the ball fields, water quality in the <br />pond, as well as sediment for contaminates. The water met all criteria for a swimming beach, soils were <br />low in heavy metals and within normal levels and there were no contaminants of concern. Salt in the <br />water may be a problem in the future, but not at this point. Mr. Statz stated that if a build up of salt levels <br />in the soil becomes a problem there will be ways to mitigate this. Committee Member Seeley asked if <br />there were plans to continue testing on a regular basis. Both Mr. Statz and Mayor Capra said this <br />requirement was part of the Storm Water Management Plan. Mr. Statz stated the pump is being designed <br />to never suck water from the top (eliminating oil and greases that may float on the top) or off bottom 2 -3' <br />so sediment will not be pumped. The system will be able to pump enough water to provide 1" of water <br />74 <br />
