exception of an ultimate need for a positive outlet for the area at the inter- section of Driscoll Street N.W. and 176th Avenue N.W. The ponding sites and the road ditches presently assimilate the storm water run-off into the ground by percolation. While the existing ponds and channels generally operate effectively, with an i~o~ease.~in development and as additional areas are surfaced, an increase i~ storm water run-off could be anticipated. This could, dm)turn, overtax the present storm drainage system at the intersection of Driscoll St. N.W.' causing occasional flooding. Proposed Improvements: The present street and drainage system provides an operational street and drain- age, 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. Str6et Improvement: The existing 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 1½" bituminous surface. This section is equivalent to a 5rton design -2-
