VIII-A-1 MEMO To: From: Subject: Date: Honorable Mayor and City Council Members Tom Montgomery Informational Presentation - Lock and Dam Access Road and Trail hnprovements January 8, 2001 The following is some general information about the proposed Phase I Riverfront improvements that I will be presenting to the Council at the January 16th meeting. I. IMPROVEMENTS , The Phase 1 Riverfront improvements consist of the following improvements; ~ Reconstruct the Access Road - The existing 24 ft. wide Lock and Dam Access Road will be reconstructed with concrete curb and gutter to a 28 ft. width. No parking will be allowed along the roadway. ~ New Alignment - The Lock and Dam Access Road will be constructed on a new alignment beginning at the bottom of the hill coming down from 2nd Street. The new alignment will swing towards Lake Rebecca to create an area for an interpretive center and bandshell. The new alignment will swing back towards the river to enter the Koch tank fann property near the location of the existing main gate. The new alignment will cut through the Koch tank fann property near the river side ofthe old tank locations, before swinging riverward to match the existing access road alignment at the downstream end of the Lock and Dam property. A new entrance to the Mississippi River public access boat ramp will be created that will separate the boat ramp activities from the Lock and Dam Access Road. ~ Trail Extension - The existing Riverfront Trail will be extended upstream from the public access to connect with the existing trail system through the Lock and Dam property. This trail extension will be 10ft. wide and will generally be constructed over the existing road alignment. Another new trail will be constructed from 2nd St. down to match into the existing Riverfront Trail at the bottom of the hill. Due to space constraints and steep side slopes, this trail will be constructed at an 8 ft. width. ~ Storm Sewer - Storm sewer will be installed as part ofthe road improvements. Some of the storm water will be directed to the existing Lake Rebecca outlet pond. Farther upstream, storm water will be discharged into small settlement basins and be allowed to infiltrate over the natural area between the new road alignment and the trail extension. ~ Trail Lighting - Xcel Energy will install decorative lights along the new trail.
