LARKIN, HOFFMAN, DALY & LINDGREN, LTD. Mr. Craig Waldron November 26, 1985 Page 9 5. Ramsey County plans to upgrade the intersection of Cleveland Avenue and County Road D in 1986-87. This upgrading will include limited widening on the west and north lanes and traffic signal control. The Traffic Analysis concludes that the upgrading will enable the intersection to effectively accommodate the existing volumes and and post -development volumes projected for the Centre Pointe Development. 4. Provision of Drainage and Erosion Control Consistent With City and Rice Creek Watershed District Standards. The proposed Centre Pointe Development provides drainage and erosion control measures consistent with City and Rice Creek Watershed District standards. As shown on the grading and drainage plans submitted in support of the Application, final grading plans respect, to the maximum extent feasible, existing contours. Surface water run- off from the Property is directed into two systems. The first is an existing storm sewer system that runs along Cleveland Avenue and through the northern portion of the Property and the second system is the existing ponding area to the south of the Property on land controlled by the Minnesota Department of Transportation. This ponding area currently receives surface water runoff from the Garrett Trucking use on the southern portion of the site. Internal storm sewer will be provided throughout the Property to connect into these two systems. The existing outlet into the MnDot pond to the south of the Property will be expanded. Consistent with City and watershed district requirements, the post - development rate of runoff will be equal to or less than the pre - development rate of runoff. This will be achieved by installation of a series of. on -site ponds throughout the Property and parking lot storage in loading areas. Subject to further analysis, some restricted rate control may also be provided on the roofs of parking structures. Ponds will be designed for the 100-year storm event. All of the on -site ponds will be equipped with baffled weirs and/or skimmer devices. A separate pond will be provided on the southern portion of the property to filter storm water runoff from the Property prior to discharge into a pipe for ultimate discharge into the existing pond on MnDot property. Erosion control measures during construction will include installation of sediment fence and/or filter fabric and vegetation of disturbed areas as soon as practicable. 5. Utilities. As shown on the utility plan submitted in support of the Application, water will be looped through the internal public roadway for ultimate connection back into Cleveland Avenue. Existing facilities have adequate capacity to serve the proposed development.
