SEH October 6, 2005 Mr. Michael Grochala Community Development Director City of Lino Lakes 600 Town Center Parkway Lino Lakes, MN 55014 -1182 Dear Mr. Grochala: RE: Lino Lakes, Minnesota Betty's Pies Site Plan Review SEH No. A- LINOL0305.09 14.00 Identified below are our review comments for the proposed Betty's Pies site at Legacy at Woods Edge, prepared by Hartford Group. Plans for the proposed building were submitted to the City of Lino Lakes for review on October 2, 2005. Erosion Control and Grading Plan (Sheet C3.0) 1. It appears that a large portion of the sidewalk on the north side of the building has cross slopes exceeding 2.0 %. These slopes exceed the maximum cross slope of 2% as . set forth in ADA Accessibility Guidelines. Utility Plan (Sheet C4.0) 1. The rim on STMH 101 appears low. Verify this rim elevation is correct. 2. No information is shown for the grading of the ECS Drainage System. This information must be shown on the plans. 3. The cover over the 12" HDPE pipe from STMH 101 to the ECS Drainage System is inadequate along some of its length near the outlet. As shown, less than one foot of cover will be provided over the top of the pipe. The full pavement section of 4" of bituminous and 8" of class 5 aggregate must be maintained over the pipe. Insulation or the pipe itself should not impact the pavement section. 4. Roof drains are shown on the plan with a note indicating roof storage is to be used for rate control and reference the architectural plans. The architectural plans show the roof drains but do not indicate how rate control will be maintained, and refer to the mechanical drawings which were not provided. The usage of roof storage to hold runoff from a 2.5" storm event was one component of the hydrology model submitted to and approved by Rice Creek Watershed District and is an integral part of the hydrologic design submitted by Hartford in this submittal. Without roof storage, the central pond/infiltration basin, as currently shown, will be undersized. Roof storage and rate control for a 2.5" storm event must be utilized on this building consistent with the hydrology model originally approved by Rice Creek Watershed District. Information describing how this will be done must be submitted for review. 5. The locations and elevations of the sanitary and water main stubs on the west side of the building have been revised as a part of the construction of Town Center Parkway. SEH will provide these locations and elevations so the plans can be revised.
