Design Construction Impacts
· Project design and right of way costs have increased, however the current construction estimate is lower than the allocated budget and will be able to absorb these additional costs to keep the total project cost within the original budget. Project design increases of $650 K are the result of expenses incurred to update environmental reports, the Access Point Decision Report, higher than anticipated bridge design and Access Hearing Plan preparation costs. The right of way cost increase of $7 M is the result of more parcel impacts than anticipated and increased property values. Some construction costs savings come from purchase of credits from a mitigation bank to mitigate for the project's wetland impacts. In this case, the cost to purchase credits is substantially less than the cost of constructing a mitigation site.
· This project changes access rights and traffic movements to residential, farm, and commercial property.
