<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 $158.400
<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,
