Feasibility Report Bunker Lake Boulevard Extension City of Ramsey inch bituminous overlay. The proposed Phase I two-lane design will be located within the right-of-way to provide future flexibility in roadway expansion with minimal modifications to what will be constructed. The north curb is recommended to be placed 34 feet north of the right-of-way centerline. With future mirrored construction on the south side of the right-of-way, this would accommodate five 12 -feet lanes with a 4 -feet curb reaction area, plus adequate boulevard areas for additional right turn lane incorporation. Ultimate expansion of the road to two through -lanes in each direction with dedicated left and right turn lanes will need to be evaluated as additional development occurs. 2. Puma Street Improvements to Puma Street are not part of the petition, but have been evaluated at the City's request because of the requirement to extend Bunker Lake Boulevard to Puma Street, a distance of about one-half mile. Two options have been evaluated for Puma Street improvements. The first is a minimum improvement whereby the existing roadway is widened from its current 18 feet width to 24 feet and paved with 2 -inches of bituminous. The second option is a cursory analysis to perform a more significant upgrade to the road to a 32 -feet wide street with curb and gutter with full base and pavement improvement. 3. Bituminous Trails A 10 -feet wide bituminous trail along the north side of the Bunker Lake Boulevard improvement has been included in the Phase I improvement. In addition, cursory evaluations of trail improvements along Armstrong Boulevard and Puma Street have been provided in the cost analysis. A trail along the west side of the Armstrong Boulevard right-of-way has a number of issues to be considered related to wetland impacts, tree removal, grading and retaining walls as depicted on Figure 7. 6 Prepared By: R16.102774 Bolton & Menk, Inc.
