city of Ni BRIGPO\ the city that Rinks for you interoffice MEMORANDUM to: Janice Gundlach, City Planner from: Craig Schlichting, Senior Engineering Supervisor subject: Village Orthodontics date: August 12, 2013 The Engineering Department has reviewed the site plan for the proposed addition Village Orthodontics and we offer the following comments; 1. The swale on the south side of the addition is 1%. With the placement of sod it is likely that water will need to build in certain areas before it reaches the pipe. The owner should be aware of this. Consider providing finish grade hubs along this swale, or build the bottom of the swale with rock/concrete to aid in water movement. 2. The south side swale is directed to a pipe, and it is not clear if proper cover can be placed on this pipe. Consider exposing block at the building corner to avoid pipe placement. 3. The adjacent parking lot spot elevations are not indicated, please add these to the drawing. It does appear that the adjacent lot drains away from this property and down the slope through a curb cut. 4. The drainage provided between the new addition and previously reviewed building plans is flat. Trench drains are provided, but the freeze/thaw of melting snow is a primary concern, as this discharge flows through the handicap stalls. I like the planted areas, but I envision these areas being used for snow storage, which adds to freeze/thaw concern. Design the concrete to have some fall from the staff entrance to the handicap curb cut to allow water to flow out even if a trench were plugged with snow/ice.
