Port Huron City council voted unanimously at the March 12 meeting to approve site plans for a new Blue Water Area transit center in the south parking lot of McMorran Place.  The $9.8 million project will be paid for by a $6.86 million federal grant that has already been secured, $1.75 million from the state of Michigan and $1.2 million from the Blue Water Area Transportation Commission.  Jim Wilson of Blue Water Transit says they still need to complete an environmental assessment as well as waiting for approval from the Federal Transit Administration.  Once final approval is in place, Blue Water Transit will proceed with purchasing the property from the city and begin the construction process.  Wilson states there are concerns about possible historical artifacts underground.  The State Office of Historical Preservation is one of the parties that must sign off on the project and they might have to do additional testing to see if there are significant artifacts underground.   Also any possible environmental contamination must be determined along with what remediation is necessary.  Once the FTA gives approval, Wilson says he thinks construction should take about twelve months, and that work is expected to begin sometime this fall.
