Shoring up the dune

The city is taking mountains of sand from City Beach and hauling it by dump truck to Mulligan's Hollow to fix a broken dune.

City public works crews are close to wrapping up the sand move, as well as work to replace a ruptured water line that caused the mess more than a month ago. Once the line has been fixed and the sand is in place, city officials will replant vegetation lost in the March 2 dune washout.

Grand Haven Public Works Director Bill Hunter said the 119 trees planted on the dune will likely be mature.

“A variety of red oaks, sugar maples, and there will be some black cherry and hemlock,” he said.

A variety of grasses will also be planted to shore up the hill.

“We’re also going to have to install an irrigation system to irrigate it,” Hunter said. “And we’ve got to monitor it for the next five years.”

The monitoring is needed to determine if the dune is re-establishing itself.

Grand Haven resident Doug Jaynes said he couldn’t help but notice all of the sand moving from the beach to the hillside.

“I've never seen the sand hauled away like they are doing this year,” he said. “The dump trucks have been running all evening for what seems like a week now.”

There have also been some concerns by residents who say the use of beach sand won’t be good for the hill restoration.

Ahhh, no, beach sand has never been hauled away like they are doing because the hill that holds our drinking water supply tanks has never washed out from a ruptured pipe before. Restoring the hill with the same sand that built the dune the water tanks sit on is logical, otherwise you would have to pay for and transport different aggregate to perform this fix.
It is merely a stabilized dune, all sand! That's why it washed out like it did.

I wish that I had confidence in their decision to remove that much sand from the beach area.
They have significantly changed the slope and grade. I would really like to know who consulted with the city to determine that removing all that sand would not have adverse effect down the road. Next fall and early winter when the sand blows and piles up against the snow fences.
It's going to be very interesting to see how much further the water comes up unto the beach. I also don't quite understand the logic behind trucking all that sand from the beach.
All the way over to Mulligans Hollow (fuel, man hours, wear and tear). When there is a hugh amount already over there that washed down the dune. And it is still there sitting at the bottom of the dune. Why not take the time to reclaim as much of that sand as possible? Put it back where it came from. Then truck it in if you need more to finish the job. It might take a little longer to reclaim it. But I wouldn't think that it would have been any more time consuming. And certainly seems like it would have been less expensive to do that, than run dump trucks from the city beach back to the dune for days. To late to rethink things now. Oh well, we'll see. They can always dredge the lake if they need to put the beach back next spring.
