ARDEN HILLS CITY COUNCIL—May 26, 2009 requirements need to be met in order for the City to obtain the permit to build the road. The number of rain gardens being constructed is what is necessary to meet the requirements. Councilmember Holmes stated that she did not agree with the number of rain gardens being required. She stated that she had talked with Doug Thomas, from Rice Creek Watershed District, and he had stated that the Rice Creek Watershed District does not mandate these types of things. She asked if the City had been told that they were required to have fifteen rain gardens in the locations indicated on the map. City Engineer Bloom stated that the storm water that comes off the roads needs to be treated to a certain threshold and the number of rain gardens is based on a specific calculation used by the Rice Creek Watershed District. The location of the rain gardens was not specified just the amount that would be required to meet the performance standard. Councilmember Holmes asked if there were other options that could be utilized to meet this requirement. City Engineer Bloom stated that catch basins do not infiltrate the water. She clarified that the volume of water that comes off the road and goes into the storm sewer system needs to be reduced. Councilmember Holmes stated that there were several neighborhoods that did not have rain gardens. She asked why this particular neighborhood would have fifteen. City Engineer Bloom stated that the other neighborhoods had been reconstructed prior to the Rice Creek Watershed District requirements for infiltration. Councilmember Holmes asked if the rain gardens were part of the agreement being presented. Civil Engineer Giga stated that the location of the rain gardens was based on those residents that had expressed interested in rain gardens. Educational materials were provided at each of the meetings pertaining to what a rain garden is and how to maintain a rain garden. The residents are asked to maintain the rain gardens in front of their homes. Councilmember Holmes asked if the resident had not expressed interest in the rain garden what would happen.
