REQUEST FOR COUNCIL ACTION Date: March 22, 2021 Item No.: 9.e Department Approval City Manager Approval Item Description: Approve Resolution Awarding Contract for RCD 4 Storm Sewer & Twin Lakes Trail Improvements 1 B ACKGROUND 2 Over the last year, City staff has been working with the Rice Creek Watershed District (RCWD) to 3 develop plans to convert Ramsey County Ditch 4 (RCD 4) to a piped system. The existing ditch, 4 located between Fairview Avenue and Lincoln Drive, runs from County Road C up to Terrace Drive. 5 Staff was motivated to request this collaboration due to the extensive redevelopment adjacent to 6 RCD 4 with the Twin Lakes Station Plat as well as the redevelopment of 2700 and 2720 Fairview 7 Avenue on the west side of RCD 4. The current ditch presents significant maintenance challenges, 8 experiences loss of drainage function due to erosion, thick vegetation and debris buildup in the open 9 channel, and delivers excess sediment downstream to Oasis Pond which reduces the pond’s overall 10 function as a stormwater storage device. Further, actual maintenance activities by the District would 11 have negatively impacted adjoining properties and would have required the implementation of a 12 wide easement area which would have resulted in a burden on these commercial properties. 13 On July 27, 2020 the City Council approved a Cooperative Agreement with RCWD for RCD 4. As 14 part of the agreement, RCWD’s engineer designed the storm sewer improvements which includes 15 replacing the ditch with an 84 inch pipe and other improvements. This agreement formalized a cost 16 participation which caps the District’s costs at$1.09 million with the City of Roseville responsible 17 for the balance of the remaining costs. The agreement also formalized the transfer of the ditch to the 18 City of Roseville, which the City now owns as of February 24, 2021. 19 Additionally, Community Development staff worked with the developer to identify a feature for the 20 adjacent properties that would benefit all current and future development adjacent to the ditch. To 21 that end, it was suggested that a trail be constructed on the top of the new pipe where the current 22 ditch is located. This would provide a linear park-like feature through the area and allow 23 connections between current and future developments across the current ditch area. In recognition 24 of that benefit, Community Development negotiated a contribution from the new development in the 25 area in the total amount of approximately $2 million. This amount will go towards the cost of 26 constructing the pipe, the trail itself and the landscaping along the trail corridor. 27 On September 28, 2020, Council approved entering into a Professional Service Agreement with 28 WSB for Twin Lakes Trail improvements. The Twin Lakes Trail plans were developed over the 29 RCD 4 Storm Sewer Plans to provide a trail connection from County Road C to Terrace Avenue. 30 The trail is a 10-foot-wide bituminous trail including lighting, trash receptacles, benches and 31 landscaping including trees. Additionally, trail connections will be made to the following adjacent 32 properties; one shared by 2700 and 2720 Fairview Avenue on the west side of RCD 4, one to the 33 commercial areas north of RCD 4, and three to the Oasis at Twin Lakes and the Harbor at Twin Page 1 of 3
