To alleviate the flooding on Limonite Street would require storm sewer construction to Kamacite Street N.W. or construction of a ponding area. To alleviate the other flooding problems on the other streets would require cross street culverts and drainage easements as proposed on Exhibit A. The existing ponding sites and the road ditches presently assimilate the storm water run-off into the ground by percolation. While the existing ponds presently operate effectively, with an increase in development and as additional areas are surfaced, an increase in storm water run-off could be anticipated. This could, in turn, overtax the present storm drainage system unless positive outlets are provided. However, this is not likely to occur until development densities increase at the t~me municipal utilities are installed. Proposed Improvements: The present street and drainage system provides an operational street and drainage network. Therefore, it is our recommendation that the present rural street section and drainage system be maintained with only minor changes to limit the disruption to the abutting property and minimize the costs of the improvement. Street Improvement: The existing residential streets are proposed to be widened and shaped to accommodate a minimum street width of 26 feet, as shown on Exhibit B. The streets would be paved 24 feet wide with a variable gravel shoulder a minimum of I foot wide. The street section proposed would be narrower than the City of Ramsey's standard rural street section, but would minimize disruption to the adjacent lots during construction since the street width proposed generally follows the present street section width. The street section proposed as shown on Exhibit B consists of a 3 inch gravel base with a 1~" bituminous surface. This section is equivalent to a 5-ton design in accordance to the Department of Transportation specifications. This section has been previously used in the city and other communitte~ with no detrimental effects. It is estimated that this street section has a life expectancy of 15
