111E III...:; U `IIIVIIf;;: SUMMARY The City of Ramsey has identified the need to prepare for continuing development of The COR. The purpose of this analysis is to provide an update to a previous analysis, dated June of 2018, and determine the necessary public infrastructure and associated costs required to allow the remaining, undeveloped portions of The COR to develop. Additional analyses have supplemented the original report since 2018, including geotechnical evaluations, Ramsey Parkway median analyses, wetland delineations, and traffic counts. Much of the information from the original report has been carried forward with this update. For reference, the following figures and exhibits are contained in the appendix of this report: • Appendix A includes a previously prepared Land Use Plan for The COR, along with roadway related graphics from The COR Design Framework plan and Citv's Comprehensive Plan. • Appendix B includes figures referenced throughout this study and tree inventory tabulation, • Appendix C includes a geotechnical evaluation dated June 27, 2018, • Appendix D includes a wetland delineation report, completed in October 2022. The delineation is currently being reviewed by the Lower Rum River Watershed Management Organization (LRRWMO), • Appendix E includes the traffic counts collected in The COR in 2022, and • Appendix F includes previously conducted analyses within The COR In addition to this analysis, there are other improvements under discussion and/or design. Each of the these has the potential to impact the developments within The COR area. Based on information provided by the City, project costs have also been developed for the following: • Regional Stormwater Retention Pond (The Waterfront) - Construction methodologies, sequencing strategies, and timing of pond construction. • The Waterfront, Phase 1 - Park features adjacent to the regional stormwater retention basin and along Center Street are currently in the schematic design phase. Cost estimates were developed for each improvement. These estimates are based on recent bid pricing and similar projects. All costs presented in the following pages are presented as 2023 costs. • The total for the roadway, trail, sidewalk, street lighting, sanitary sewer and water main improvements is estimated at $10,612,000. • The total trunk related improvements for sanitary sewer and storm sewer is estimated at $513,000. • The total landscaping improvements along Sunwood Drive from Zeolite Street to Sapphire Street is estimated at $802,000. • The total for regional stormwater retention pond excavation, grading, and tree preservation is estimated at $3,140,000. • The total for mass site grading of the remaining undeveloped land within The COR, including wetland mitigation and tree preservation, is estimated at $3,796,000. • The total for The Waterfront Phase 1 above ground features are estimated at $4,218,000. • The total for Municipal Plaza Improvements is estimated at $4,091,000. • The total for Municipal Plaza Stormwater Reuse Improvements is estimated at $2,285,000. The costs presented are considered project costs and include 30% contingencies and project development costs (administrative, engineering, and fiscal). A more detailed cost breakdown is included in the Cost Analysis section. Prepared by: Bolton & Menk, Inc. EXECUTIVE SUMMARY The COR Analysis I OR1.129128
