Officials told officials in an October 27 interview with U.S. Senator Tom Carper that coastline stabilization and rainwater management systems are reducing flooding along Red Avenue Bay on Dewey Beach.
Dr. Marianne Walch, coordinator of Delaware’s Inland Bay Science and Recovery Center, said that frequent storms and super high tides have caused Read Avenue, which has 30 acres of drainage area, to experience the worst flooding in Dewey.
“You don’t have to be a scientist to know what’s going on,” Carper said. He pointed out that officials have recorded the hottest decade on earth and one of the most active Atlantic hurricane seasons in history, which is determined by sea level temperature. Pushed up.
The project was completed in the spring and includes an active coastline and three-foot sand dunes, tidal gates and sewage pipes, offshore woven oyster reefs that stabilize the coastline and provide habitat for small animals, and recreational kayaks.
The tide gate valve is closed at high tide to prevent the bay water from flowing back into the rainwater drainage system. Walch said that the sand and dunes on the coast dissipated the wave energy that caused the flooding, and the sand-filled basket structure stabilized the dunes.
Dewey Beach Mayor Dale Cooke said he is grateful for the cooperation of CIB and the state and town officials involved in the project.
Reid Avenue resident Phil Winkler (Phil Winkler) said that the coastline where they live has greatly reduced flooding. He said that since the coastline was built, there have been at least three major high tides, three feet above sea level.
He said: “In the past, this would cause Gulf water to flow into Read Avenue, thereby destroying the lives of all residents here.” “The new 3.5-foot berm across the entire waterfront effectively prevented Gulf water from entering Read Avenue.”
Winkler said that during the heavy rain from October 12th to 13th, there was almost two inches of rain on Reid Street at high tide, which caused a flood on Reid Street because the rain could not spread into the bay.
He said: “However, once the tide starts to subside, the rain will quickly run away within two hours.”
Winkler said that he used the dye given to him by a friend of a hydrologist in Texas to test the newly installed damp-proof gates three times and confirmed that the gates were working. Winkler said that the dye is sodium fluorescein, which is harmless to humans, fish or any other organisms.
Winkler said: “I put some dye on a cotton ball in a weighted plastic bag. These plastic bags have holes to allow water to circulate.” “Then put the dye bag in the outlet pipe during the last hour of high tide. In front of.”
Winkler said that the water around the end of the pipe is bright green, while the water above the junction box on the shore has no color, indicating that the tidal gate in the outlet pipe prevents the bay water from flowing into the street as designed. .
He added: “In addition, the dampers in the three drainage pipes only allow water to flow into the bay, and not from the bay to land.”
He said: “This new natural barrier project will protect nearby residents and businesses from high tides and higher storm surges that continue to be seen in coastal areas as global temperatures rise.” “These are the investments we need – Strengthen our community’s funds and projects while restoring habitats and protecting ecosystems.”
Kaper said that one of his first tasks is to increase investment to make communities, transportation, drinking water and wastewater treatment infrastructure more resilient to the worsening climate crisis.
He said: “Natural infrastructure is a wise and effective way to protect communities from the climate crisis, but it can only solve the symptoms of the climate crisis.” “We also need to pay attention to coastal erosion, sea level rise and worse The root cause of extreme weather.”
Carper added that air pollution captured by thermal energy is warming the earth, causing ice sheets to melt and sea levels to rise.
He said: “Warmer temperatures and higher sea temperatures intensify more frequent and more destructive tropical storms.” “If we don’t take any measures to drastically reduce carbon emissions-the villain of the climate crisis, and the immediate destruction In comparison, the destruction and destruction we see now will be pale.”
