Grand Haven Project Manager Julie Beaton said the intersection of Y and Harbor drives will be closed beginning Monday, as crews begin installing a secondary 30-inch raw water intake main that connects the state park pumping station to the Northwest Ottawa Water Treatment Plant, 30 Sherman Ave.
“The intersection at Y Drive and Harbor is going to have an 18-foot excavation,” Beaton said. “That will be a real hard closure for two and a half to three weeks.”
Because of this, traffic getting to any location south of Y Drive will be forced to use Lake or Grand avenues as a detour, and people who want to access the YMCA or Mulligan’s Hollow will be required to take Sherman to Mulligan’s Drive.
Once crews are done at the Y Drive intersection, Beaton said they will work their way up through the Mulligan’s Hollow area installing the main where they will eventually connect to the water plant.
According to Kevin Kietzman — a civil engineer with Fishbeck, Thompson, Carr & Huber — 30 percent of the project is being paid for by Ottawa County for the raw water intake installation, and the remaining portion is coming from the city from its 2008 public infrastructure bond for improvements to water and sewer lines.
Beaton said the age of the water and sewer lines beneath Harbor Drive meant it was time for replacement.
“I think they were all beyond their life expectancy,” she said. “There’s nothing less than 40 years old.”
Work will also soon start on restorative projects including adding a final course of asphalt from Y Drive to near Lake Avenue, the installation of curb and gutter, new sidewalks and crosswalks, new tree planting, and dunegrass restoration.
