Resolution 8347, Authorizing Preparation of Feasibility Report for Mustang Drive Page 2 shallow ponding in the street and grass boulevard areas, while larger storm events will cause street ponding to a depth of about one foot that extends 70 feet to the north of the intersection. A significant contributor to this runoff is associated with the freight distribution property on the south side of Mustang Drive. A drainage study was prepared in 2007 by Stantec (formerly Bonestroo) for Mustang Drive/Circle intersection. The study detailed the drainage issues and inadequacies, and also provided four options for improving flooding at this intersection. These options involve one or more improvements involving street grades, drain inlet and storm sewer modifications, and new storm ponds. Public Works is recommending an option where the existing street profile would be modified to direct excess runoff north along Mustang Circle, requiring reconstruction of the road profile to remove the high point located 70 feet north of the intersection. This will also require modifications to two existing entrance drives to match the revised curb line elevations. This option will direct excess flow to the existing low point in Mustang Circle. The existing drainage channel (ditch) west of the street may also need to be regraded to provide adequate capacity. Funding/Chapter 429 Process Improvements to Mustang Drive/Circle has been discussed for several years and included on the Capital Improvement Program and previous years’ budgets. The 2015 draft budget includes the following funding: TIF District #2 (420-4650-7050): $ 450,000 Stormwater Fund (745-4415-7050): $ 75,000 Total $ 525,000 The City Council indicated to staff during budget discussions recently that they would like to use special assessments as an additional funding source. This process is mandated by Minnesota Statute Chapter 429 and would assess a portion of the costs to the benefitting abutting properties. Chapter 429 has specific steps and activities that must occur during the project development (see attached checklist). The first step is to order a feasibility report which will consider whether the project is necessary, feasible, and cost effective. The report will have a detailed cost estimate for the improvements, including amounts to be assessed to each parcel and the methodology used to calculate the proposed assessments. Other report items include permits needed, land issues, and a layout of the proposed improvements. Some preliminary engineering design and analysis for the storm drainage improvement options may be necessary for completing the feasibility report. Selecting a Consulting Engineer Public Works Engineering is soliciting proposals from qualified consulting engineering firms based upon a Request for Proposal (RFP) document. The RFP contains background information and a work scope description for the entire project. Proposals are due to Public Works Engineering by noon, Monday, December 8, 2014. A summary of the proposals received and a recommendation will be presented at the Council Meeting that night. Recommendation: Public Works recommends the pavement and stormwater improvements to Mustang Drive/Circle. A recommendation for authorizing a consulting firm will be available at the Council meeting. If the Council wants to proceed with special assessments, a feasibility report is recommended to be ordered. In addition, a topographic survey is also recommended at this time due to weather.
