Clam Pass dredging ushers in slow-motion race against time

A dredger has begun digging sand out of Clam Pass in North Naples in a slow-motion race against time to save a dying mangrove forest.

Heavy winter rains and poor tidal flushing at the mouth of the choked off pass have flooded patches of mangroves that grow below the Pelican Bay neighborhood’s high-rise condos, causing an 8-acre die-off. More mangroves are showing signs of stress, biologist Tim Hall said. He said the die-off might not be over.

“We don’t know yet,” Hall said. “It’s too early to tell whether we’ve hit the bottom of that downward slide.”

Hall, representing a Pelican Bay taxing district, has been trying to get a Clam Pass dredging permit from the U.S. Corps of Engineers for almost two years. The review faced hurdles with endangered species like the smalltooth sawfish and red knot.

Besides that, dredging at Clam Pass has generated intense public scrutiny over its effect on sea grass beds and boating access between the Gulf of Mexico and the Seagate neighborhood and a county kayak and canoe launch.

Reviewers signed off on the 10-year permit — Hall called it a compromise over the extent of dredging and what estuary conditions would trigger new dredging — and Collier County commissioners declared an emergency to speed up the hiring of the dredger.

Work has been going on for about a week, and is on schedule to be completed by the end of the month and the official start of sea turtle nesting season.

“The weather’s been good and he’s made very good progress,” said Neil Dorrill, director of the Pelican Bay Services Division, the arm of county government overseeing the dredging.

A mangrove die-off grew to 50 acres in the Clam Bay estuary before a 1998 dredging project restored flows to the forest. Crews were back at work at Clam Pass in 2002, 2007 and 2013 — another emergency dredging to reopen the pass.

Collier County was working to get a new 10-year dredging permit at the time, but frustrated county commissioners put that on hold to focus on an emergency permit and transferred authority for Clam Pass to the Pelican Bay taxing district.

The emergency dredging in 2013, by design, did not remove all the sand from interior portions of the pass, accelerating shoaling that has caused the new emergency.

Both emergencies triggered impromptu volunteer brigades of beachgoers to take turns shoveling a path from the Gulf of Mexico to the back bays of Clam Pass.

Collier County plans to close its Clam Pass Park in North Naples on Wednesday and Thursday because of construction traffic related to a Clam Pass dredging project. The park’s boardwalk will be open but access to the beach from the boardwalk will be closed. The park’s canoe and kayak launch also will be closed.

Shinnecock Inlet Dredging Project In The Works

The U.S. Army Corps of Engineers is slated to survey the Shinnecock Inlet to prepare for another dredging project there, while U.S. Representative Lee Zeldin works to get the project started as soon as possible.

According to Jennifer DiSiena, Mr. Zeldin’s communications director, the Army Corps will conduct a survey this spring to estimate how much it would cost to dredge the channel just south of the jetties. Mr. Zeldin had received a letter from the Southampton Town Board last month asking for his assistance in alerting the Army Corps that the waterway needed to be dredged once again.

In an email this week, Ms. DiSiena said Mr. Zeldin hand-delivered the letter to Army Corps representatives when he last met with them in Washington, D.C.

“The congressman and our staff are working closely with the Army Corps to push this project along, especially working with the Coast Guard to get an emergency designation so that we can expedite the process, because this is becoming a navigation hazard for our local community,” Ms. DiSiena wrote.

Kenneth Wells, chief of public affairs for the New York District of the Army Corps North Atlantic Division, did not immediately return a call seeking comment.

According to the Town Board’s letter, dated March 2, a large sand deposit has been migrating west off the inlet’s eastern jetty, resulting in a sandbar that has led to shoaling, creating a navigational hazard for boaters. Because of that, the board asked that Mr. Zeldin convey the urgency of the problem to the Army Corps so the situation does not threaten the commercial and recreational fishing businesses that rely on the inlet and boost the local economy.

“Running aground could create serious safety concerns for the captain and crew of these vessels. Boats are now routinely forced to wait outside the inlet during low tide periods before they can safely return to port. The accumulated sand may also complicate lifesaving efforts for the U.S. Coast Guard, which maintains a station in this area,” the Town Board wrote to Mr. Zeldin. “Coast Guard Station Shinnecock is currently broadcasting a radio message to all mariners warning of the conditions in the inlet due to the shoaling.

“We hope that, with your assistance in conveying the urgency to the Army Corps of Engineers, this area can be dredged expeditiously,” the letter continues. “We further request that any dredged materials be stockpiled in a town-designated spoil site to be made available for dune restoration along Dune Road in over-wash areas. There are several areas to the west where over-washing is threatening the integrity of the road and creating flooding of nearby residences. The town’s stockpile of sand is largely depleted.”

There have been several dredging projects at the Shinnecock Inlet over the last few years. In 2013, the Army Corps completed a large dredging project that removed 450,000 cubic yards of sand that was then used to restore beaches lost during Hurricane Irene in 2011 and Superstorm Sandy in 2012, as well as to bolster the Tiana Beach region. In late December, the Army Corps wrapped up another dredging project that involved clearing the western side and then depositing the spoils on the beach to the west of the inlet.

Suffolk County crews dredged the eastern side of the inlet earlier this year and used that sand to build up the shore in front of nearby homes, as well as to build up the beach in front of the Shinnecock Indian Reservation.

What is Floating Hose

Floating hose is used with dredgers for silt/gravels conveyance. The suitable conveyance matters are usually mud, clay, fine sand, fine-mid sand and so on.

Inner cover is excellent abrasion-resistance. It can protect the hose from the friction of depositional silt. And the colored indication layers can reflect the degree of the abrasion effectively. This can guarantees the normal use of the floating hose.

With the deep understanding of the floating discharge hoses, the advantages of convenience and stability have been recognized by most of manufacturers. And application of floating discharge hose at sea becomes more widely.


1. Outer cover with excellent abrasion resistance and UV protection.
2. Inner cover with excellent abrasion resistance and high quality.
3. Wearing colored indicator layer.
4. Single foam flotation casing to prevent water absorption.
5. Can bear the high pressure of work.
