• • • Eagle Brook Church page 7 area. This was required by the Watershed in lieu of the suggestion to daylight the underground "ditch" and make it an actual surface ditch. The new underground tile will daylight in a location similar to the existing tile, and discharge into the wetland. The capacity of the tile will not be changed. The ditch must not be impeded so as to cause flooding. On the other hand, increasing the ditch's capacity could drain wetlands in the area. Therefore, design of any work that affects the ditch must maintain ditch capacity. As noted in the TKDA memo, we did not receive sufficient hydraulic calculations to provide for a complete review. In addition, additional information is needed to ensure proper road drainage as well as flow from properties to the south. The applicant will be required to enter into a ponding maintenance agreement with the city. Drainage and utility easements must be created over all ponds and wetlands. Easements must be placed over the relocated draintile for Co. Ditch 72 and deeded to the Rice Creek Watershed District. As a condition of plan approval, the grading and drainage related modifications and comments as set forth in the City Engineer's memo should to be incorporated into the plans. Floodplain: The city has a floodplain management ordinance. The 100 -year flood elevation, which defines the floodplain, is 887. The western portion of the site is within the floodplain. Lowest floor elevations of structures must be at least one foot above this elevation. The church building pad is not within the floodplain and is at an elevation of 896. Access, Circulation, Parking Right Of Way: The site fronts on 20th Ave., CSAH 21, a minor arterial roadway. Ultimately, Anoka County will need a total width of 120' of right of way, or 60' on each side of the centerline. Currently, it is 33'. The Church is proposing to dedicate an additional 30' to accommodate turn lanes for the new access driveways. Access, Circulation: The proposal includes two new driveways onto 20th Ave. Southbound right and northbound left turn lanes would be constructed for vehicles entering the north driveway. This would be the entry point during church events. The southern driveway would be the exit during events. This would be managed by traffic control personnel at the driveways. During non -event times, both driveways could be used for entry and exit. As noted in the TKDA memo, the submitted plans do not provide clear information regarding the road improvements. This is necessary for a complete review. The design of access on any development project should consider not only the specific site, but potential future development on adjacent properties. The EAW review raised the question of creating road easements to provide public roads to accommodate future
