Mr. Bruce Westby, P.E. April 7, 2023 Page 2of5 • The construction of the regional storm water retention pond will allow for complete development of The COR. This construction will then allow for construction of The Waterfront amenity, and • The material generated from the regional storm water retention pond can be used as fill for the remaining undeveloped portion of The COR. This should serve to lower development costs, making the area more attractive to potential businesses. CONSTRUCTION COST ESTIMATES The COR report update, completed in 2023, presented project costs associated with the street and public utility related improvements. Those amounts were based on 2023 construction costs, and included a 30 percent allowance for contingencies and project development. Project costs were also included in The COR report for the regional storm water retention pond, mass grading, tree preservation, and park amenities. Based on The COR analysis, the following construction cost estimates, including a 10% contingency, were considered when preparing our fee estimate: Ramsey Zeolite Center Improvement Parkway Street Street TOTAL Roadway $1,2591100 $709,100 $555,900 $2,524,100 Parking $0 $0 $15 8,400 $15 8,400 Trails/Sidewalks $249,600 $199,700 $1661700 $6161000 Storm Sewer $6751200 $1131400 $1451500 $9341100 Trunk Storm Sewer $221000 $681500 $0 $901500 Watermain $3541500 $2331500 $0 $5881000 Sanitary Sewer $1701100 $1517500 $0 $3211600 Trunk Sanitary Sewer $248,800 $0 $0 $248,800 Total Costs $299799300 $194759700 $190269500 $594819500 Construction costs associated with the regional storm water retention pond include the following: dewatering, muck excavation, wetland mitigation, clay liner, and rough grading of the storm water pond area. Additionally, material will be placed on adjacent lots within The COR area and compacted to allow for building pads. Construction costs associated with these items are estimated at $5,066,800. Tree removal and preservation construction costs are estimated at $135,400 within the regional pond area and at $671,800 for the remaining areas. Total estimated construction costs for the described improvements are estimated at $11,355,500.
