MINUTES CITY COUNCIL APRIL 2G, 2006 Allan pointed out the provision in the Shoreland Ordinance for DNR review of any variance application. The City Planner indicated that the DNR will allow variances subject to receipt and approval of a Shoreland impact plan. These impact plans include grading and drainage studies of parcels to determine how drainage is being handled on the site and determine additional improvements to ensure that run-off will not negatively impact lake water. The Planner indicated that he typically sees the variance process and resulting DNR review applied to commercial projects exceeding the 30% impervious surface limitation. The Planner stated that in the Murphy's case, he views the existing impervious surface at 44% as being grandfathered in. Therefore, if the Murphy's are putting in a horseshoe driveway that is pervious surface and they are not increasing the impervious surface, Che matter would not have to go to Che DNR. Blesener stated that the end result the City is trying to achieve is Chat more water is not going into Che lake. Allan stated that the slope of the property as well as soil types would have to be looked at to ensure that no additional water is going into the lake. Blesener suggested that the City Engineer could review the plan. Allan asked if it would be easier for Che DNR to do the review. The City Planner stated that this provision was negotiated into the City's Shoreland Ordinance as a compromise for commercial areas Chat have been a problem. Allan noted that the City's ordinance has no mitigation measures that need to be followed when adding impervious surface. Allan stated that she would like to see this added to the Code, noting that an increase in run-off from this property impacts all properties in the area. Allan noted that Gervais Lake is a protected water body. Allan stated that she was concerned that allowing an exception for this property results in requests for additional exceptions. Keis stated that from his observation it appears that most of the houses on County Road B-2 along the lake exceed the 30% impervious surface limitation. Keis noted that this appears to be a limitation thaC cannot be met. The City Administrator noted that the Shoreland Ordinance was adopted in the late 1980's after most of these properties were developed. The City Planner indicated that the DNR's currenC standard is a 25% limitation on impervious surface. However, Che City is not required to amend its Shoreland Ordinance to meet the 25% standard. 8
