<br />• The construction of the regional storm water retention pond will allow for complete
<br />development of The COR. This construction will then allow for construction of The Waterfront
<br />amenity, and
<br />• The material generated from the regional storm water retention pond can be used as fill for the
<br />remaining undeveloped portion of The COR. This should serve to lower development costs,
<br />making the area more attractive to potential businesses.
<br />CONSTRUCTION COST ESTIMATES
<br />The COR report update, completed in 2023, presented project costs associated with the street and
<br />public utility related improvements. Those amounts were based on 2023 construction costs, and
<br />included a 30 percent allowance for contingencies and project development. Project costs were also
<br />included in The COR report for the regional storm water retention pond, mass grading, tree
<br />preservation, and park amenities.
<br />Based on The COR analysis, the following construction cost estimates, including a 10% contingency,
<br />were considered when preparing our fee estimate:
<br />Ramsey Zeolite Center
<br />Improvement Parkway Street Street TOTAL
<br />Roadway $1,259,100 $709,100 $555,900 $2,524,100
<br />Parking $0 $0 $158,400 $15 8,400
<br />Trails/Sidewalks $249,600 $199,700 $166,700 $616,000
<br />Storm Sewer $675,200 $113,400 $145,500 $934,100
<br />Trunk Storm Sewer $22,000 $68,500 $0 $90,500
<br />Watermain $354,500 $233,500 $0 $588,000
<br />Sanitary Sewer $170,100 $151,500 $0 $321,600
<br />Trunk Sanitary Sewer $248,800 $0 $0 $248,800
<br />Total Costs $2,979,300 $1,475,700 $1,026,500 $5,481,500
<br />Construction costs associated with the regional storm water retention pond include the following:
<br />dewatering, muck excavation, wetland mitigation, clay liner, and rough grading of the storm water pond
<br />area. Additionally, material will be placed on adjacent lots within The COR area and compacted to allow
<br />for building pads. Construction costs associated with these items are estimated at $5,066,800.
<br />Tree removal and preservation construction costs are estimated at $135,400 within the regional pond
<br />area and at $671,800 for the remaining areas.
<br />Total estimated construction costs for the described improvements are estimated at $11,355,500.
<br />SCOPE OF SERVICES
<br />PRELIMINARY DESIGN
<br />Prior to initiating design, we will meet with the City to discuss the initial project scope. Items to discuss
<br />include:
<br />• Topographic Survey of The COR,
<br />• Geotechnical and Environment Evaluations,
