ARDEN HILLS CITY COUNCIL WORK SESSION—APRIL 16, 2012 7 association was requesting a storm sewer improvement to overdesign the pipe system due to the fact grading completed in the 1970's did not allow for emergency overflow. He indicated Option 5 would address the flooding concerns for a small portion of the southern portion of the development while Option 6 would address the entire development. Ms. Larson described how the water was currently draining through the association and noted with each flood the property damage was increasing. Councilmember Holden understood the concerns of the townhome association. She was in favor of the City assisting, but not covering 100% of the expense. Public Works Director Maurer discussed Options 5 and 6 in further detail. These were the only two recommendations from Bolton& Menk that would measurably address the flooding concerns. He indicated the townhome association did not need the issue to be resolved in 2012. However, if the Council were to provide comments and select a direction to proceed, this would allow the association to prepare for potential assessments in 2013. Ms. Larson stated the association was looking for a long-term sustainable solution to stop any further property damage from occurring to the townhomes. She stated that the association has already paid a lot in storm water fees to the City. Public Works Director Maurer stated staff could further review the plans and provide the association with estimates on what assessments would be on 100% of the expense, 50% of the expense and 25% of the expense for the storm sewer improvements. Councilmember Holden questioned if the Council was in favor of funding a portion of the storm sewer improvement expense. Councilmember Tamble was in favor of assisting with a portion of the expense. Councilmember Holmes commented several residents addressed the Council in the past with drainage concerns and the Council did not provide assistance to these residents. Councilmember Holden asked if the entire association could be assessed or if it would only be the southern portion. Mayor Grant stated a full assessment would be approximately $300 if both the north and south associations were assessed. Ms. Larson indicated both the north and south associations would benefit from the improvements. She noted there was an area in the north that flooded last year. She stated that the association did not support an assessment for this project. Mayor Grant was in favor of a 50150 split on the improvement expenses. He requested staff provide the Council with a total cost for the proposed improvements, both construction and engineering.
