COST CONSIDERATIONS Costs were developed based upon phased implementation. The phasing is as depicted on Figure 4 in Appendix A. All costs presented in the following pages are 2015 costs, with no allowance for inflation. Improvement Type Phase 1 Phase 2 Phase 3 Roadway $ 1,427,000 $ 1,383,000 $ 1,626,000 Trails/Sidewalks $ 220,000 $ 146,000 $ 175,000 Storm Water Management $ 0 $ 0 $ 64,000 Street Lighting $ 143,000 $ 104,000 $ 126,000 Trunk Water $ 19,000 $ 219,000 $ 247,000 Trunk Sanitary Sewer $ 11,000 $ 188,000 $ 654,000 Total Costs/Phase $ 1,820,000 $ 2,040,000 $ 2,892,000 The above costs are considered project costs and include 30% contingencies and project development costs. Project development costs include administrative, engineering, and fiscal related costs. The roadway costs include allotments for phase transitions associated with tapering pavements sections to match in-place sections where required, and subsequent removals of the transition areas. Right turn lanes are not depicted on the graphics, but will be required. The actual right turn lane locations and lengths will be determined by the entrance locations, land use and associated traffic impacts. Costs are included for right turn lanes in the roadway estimate. Street lighting costs are based upon recent installations within the City of Ramsey. For storm water management, costs were included for manholes, catch basins, and pipe within the street sections and included in the roadway costs. No costs for ponding were included for Phases 1, and 2. For Phase 3, ponding costs were included for excavation related activities. We assumed a ponding area would be acquired through the platting process, and ponding within a development site would be expanded to include volume for roadway drainage. The Phase 2 limits are based upon the area that can be served by a gravity sanitary sewer system. The Phase 3 sanitary sewer costs include a lift station and forcemain. COST ALLOCATION ALTERNATIVES The costs, or a portion of the costs, of the improvements are typically allocated back to adjacent properties through the use of assessments, fees and other methods. The costs are typically allocated in a way that is equitable to the properties benefitting from the improvements. Public improvements that will become City owned and maintained are typically constructed through a public process, while secondary improvements are constructed by the property owner. For our analysis, we assumed the following items would be constructed through the public process: Prepared by: Bolton & Menk, Inc. COST CONSIDERATIONS City of Ramsey — Future Business Park Page 11
