Review File: Riverstone Sketch Plan Exhibits Engineering Review March 29, 2017 Page 4 of 5 The De Minimus form states that the historic impacts + the proposed impacts exceed the de minimus then the exemption cannot be claimed. Staff feels the request for exemption needs further investigation before we accept it. The request must also be reviewed by the wetland specialists at the LRRWMO as part of the approval process for the exception. Geotechnical Report: 1. The logs indicate loose to very loose sands at depth in each boring. The report must be revised to indicate how these loose to very loose sands should be addressed under the future pavements. The City must maintain the roads and requires that the subgrade be as uniform as possible to prevent differential settlement of the pavements. Draft EAW: The following comments were generated after reviewing the draft EAW. Page 7 - Page 8 - Utility phasing needs to be clarified. The southernmost streets can be served with sewer from Bunker Lake Boulevard. The remainder of the development will send sewage to a lift station. The responsibility for construction of the lift station must be identified. The tabulation lists a loss of 0.4 acres of wetland. Commentary needs to be added justifying this loss, ie. De Minimus exemption. See comments above regarding supporting the exemption. Page 31 - The list of permits must be updated. McDonalds has withdrawn their permit application. Page 74 - The traffic study states turn lanes are not required on the existing roadways. Historically projects of this size in Ramsey have needed some traffic modifications. The traffic study commentary should be expanded to show the justification for not adding turn lanes. Page 85 - Remove the transit comment. Ramsey does not have transit in any part of the City due to low population density. Page 90 - The traffic data count sheets need to be updated. The file name lists Ramsey streets while the page header lists a St. Paul intersection. Page 128 - The diagrams do not accurately reflect the inplace roadways at the modeled intersections. The southern leg of diagram 2 does not exist and should not be shown.
