ARDEN HILLS CITY COUNCIL WORK SESSION-SEPTEMBER 21. 2009 7 IC. Update on Erosion Correction Project on the Old City Hall Trail (continued) Mr. Thomas stated he was proposing minor changes in the flow routes but stated the water would end up in the same place. Mayor Harpstead questioned if the proposed changes would create water concerns elsewhere. He stated he would be in favor of a long term solution. Mr. Thomas stated he was proposing the water flowing through a different area of the property that was heavily wooded and more naturally resistant to erosion. He explained that the townhome property slopes and drains towards the trail. The trail would need to be tipped the other direction to channel the water and flow south. Public Works Director Hoag explained that the standards for installing trails 15 years ago were different than the standards today. He noted this trail needed a two foot bench and was built too wide at eight feet along the ten foot easement. Councilmember Holden questioned when the next scheduled maintenance was for the entire trail. Public Works Director Hoag stated there has been some crack filling over the years and the trail would need major rehabilitation in the five to seven year range. Discussion ensued regarding the drainage issues surrounding the Old City Hall trail. Mr. Nelson presented the Council with his findings and felt that the trail was too big and too close to the hill. He felt the most effective solution was a retaining wall. Councilmember Holmes questioned if the retaining wall would then shift the erosion problem to the neighboring property. Mr. Nelson felt this was the case. Mr. Thomas further reviewed his proposal to change the grade of the trail to tip it away from Mr. Nelson's property.
