1. EXECUTIVE SUMMARY City of Ramsey Improvement Project 16-36 proposes to construct a storm sewer system outlet for the regional stormwater pond serving Business Park 95. Figure 1 in Appendix A shows the properties that will benefit from the proposed improvements. Figure 2 in Appendix A shows the scope of the proposed improvements. A regional stormwater pond was provided for development of the Business Park 95 properties in 1995. However, a storm sewer system outlet was never constructed so this pond remains land- locked which will limit the ability for businesses to expand within this business park, such as recently occurred when Dedicated Networks tried to expand in 2015. This resulted in the Lower Rum River Watershed Management Organization making their Permit approval contingent on the City of Ramsey guaranteeing that an outlet for the pond would be constructed in 2016. This improvement project is included in the City's current 5 -year Capital Improvement Plan for construction in 2016 at an estimated cost of $350,000. The engineer's opinion of probable costs for constructing the proposed pond outlet improvements, which is included in Appendix B, is $332,500. These costs include 10% contingency costs to account for additional costs discovered during final design, as well as 23% indirect costs for administrative, engineering, finance and legal costs. The pond outlet improvements are proposed to be funded entirely with Stormwater Utility Funds. Staff explored the use of special assessments to benefiting properties to pay for a portion of the costs, but based on project records it was determined that the City fully intended to construct the outlet improvements in the future when warranted without assessing benefiting properties within the business park. Staff therefore proposes to utilize Stormwater Utility Funds to pay for all of the improvements. The project schedule outlined in this report therefore does not account for public hearings or other required public process timelines per State Statute Chapter 429 or the City Charter. It is Staff's opinion that the proposed improvements would best be constructed as a stand-alone project in 2016, and that the improvements are necessary, feasible, and cost-effective from an engineering standpoint, and can be constructed as proposed herein.
