Grand Valley State University is slated to begin construction this spring on the $4 million Mackinac Ravine Restoration Project to address erosion that could affect nearby buildings.Although substantial measures have been taken to reduce storm water flow directed to the Mackinac Ravine, mass slope movements are evident.The development of the Allendale Campus has accelerated erosion at the ravine streambed resulting in loss of soil at the slopes providing support.Repairs are expected to begin in March or April with project completion expected in October 2017.
