1. EXECUTIVE SUMMARY City of Ramsey Improvement Project 16-36 proposes to construct pond capacity and outlet improvements for the regional stormwater pond serving Business Park 95. Figure 1 in Appendix A shows the properties that will directly benefit from the proposed improvements. Figure 2 in Appendix A shows the scope of the proposed improvements (see red line segments). 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 2016 to 2020 Capital Improvement Plan for construction in 2016 at an estimated cost of $320,000. The engineer's opinion of probable costs for constructing the proposed stormwater pond 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 improvements are proposed to be funded entirely with Stormwater Management and 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 intended to construct the improvements in the future when warranted by development without assessing benefiting properties within the business park. Staff therefore proposes to utilize Stormwater Management and Stormwater Utility Funds to pay for the proposed improvements. The project schedule outlined in this report therefore does not account for any public hearings or other public process timelines as required when special assessments are levied per State Statute Chapter 429 and/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.
