Notching Jetties

Keepin it alive, I think this is the most relevant topic I have seen on SI.

 

Ya I agree- this is actually a good topic- almost like old times when the forum was good!

I had no idea!!! But no need to worry- cause notching the jetties does not do anything!

They did it down here in Belmar- now the waves are the best around!

Seriously- they gotta stop...

 

All the jetties i surf at have recently been pumped and it really sucks but one spot is SLOWLY coming back I've noticed today. It's really maddening since it's just to fit more people. We really shouldn't be fooling with nature,imo

 

There hasn't been beaches in Deal for 100 years. Go back and look at the old aerial photos that are available. Deal is a bluff, a mini cliff almost. It's not a barrier island that is retreating.
There shouldn't even be a beach here. The coast drops off into deep water quickly which is why this area holds bigger swells.

 

In NJ the perpendicular rock structures to the beach are generally called jetties. Technically they are "groins" like you said but everyone here calls them all "jetties". They have plans to notch in different areas. They cut a path either near the shoreline, or further out to allow water/sand to flow through the jetty instead of around it.
Deal has the last remaining good jetties in NJ. Army corp plans will bury and/or notch them.

 

You're aware they notched the jetties in Belmar and Spring Lake like 10 years ago and it hasn't destroyed anything.

 

Found this information on another site that might be helpful. Although unable to verify if below list is accurate, these are the groins (jetties) that are proposed to receive notching.

Army Corps announces availability of Draft Environmental Assessment for proposed Elberon to Loch Arbour reach of the Sandy Hook to Barnegat Inlet Beach Erosion Control Project
Public comment period open until March 26, 2014

NEW YORK – The U.S. Army Corps of Engineers, New York District announces the availability of the Draft Environmental Assessment (DEA) and Draft Statement of Conformity (DSOC) for the Elberon to Loch Arbour reach of the Sandy Hook to Barnegat Inlet Beach Erosion Control Project, Section I – Sea Bright to Ocean Township and the opening of the window for the public to submit written comments regarding those documents.

With the passage of the Disaster Relief Appropriations Act of 2013, the Army Corps has been given the authority and funding to complete ongoing coastal storm damage risk management projects and studies in the Northeast, including the Elberon to Loch Arbour project, which was previously authorized as part of the larger Sandy Hook to Barnegat Inlet project but was not constructed. As part of the planning and implementation process for the authorized Elberon to Loch Arbour project, the New York District has updated prior engineering and design efforts, physical surveys, and environmental compliance in putting together the recently completed Draft Hurricane Sandy Limited Re-evaluation Report (HSLRR).

The DEA and DSOC, as well as the Draft HSLRR for the Elberon to Loch Arbour project and associated documents, are available on New York District’s web site at www.nan.usace.army.mil.

Public comments on DEA and DSOC regarding this proposed work should be submitted to:
The U.S. Army Corps of Engineers, New York District Planning Division-Environmental Branch (ATTN: Mr. Howard Ruben) 26 Federal Plaza, New York, New York 10278-0090

Public comments can also be submitted by e-mail to Project Biologist Howard.Ruben@usace.army.mil and Project Manager Jenifer.E.Thalhauser@usace.army.mil.

Further instructions for submitting comments can be found in the Notice of Availability of Environmental Assessment document on the District’s site. Comments received by March 26th regarding the DEA will assist in the agency’s evaluation of the project changes and will be reflected in the project record.

The Sandy Hook to Barnegat Inlet project is a partnership between the Army Corps and the New Jersey Department of Environmental Protection.

The proposed Elberon to Loch Arbour project calls for the placement of roughly 4.5 million cubic yards
of sand to create a 100-foot-wide beach berm 12 feet above mean low water. The project also calls for the modification of six groins to allow for the movement of sediment and modifications to 16 outfalls to ensure their continued operation after the beach berm is created and to prevent their operation from negatively impacting the newly constructed beach berm.

Pending the Environmental Assessment, required reviews of the Elberon to Loch Arbour Reach Draft Hurricane Sandy Limited Re-evaluation Report and the signing of a Project Partnership Agreement with the DEP, the Corps expects to award the construction contract for the Elberon to Loch Arbour project in summer or fall of 2014.

 

can one of you that's opposed to this actually explain WHY other than "someone told me it's going to ruin the surf hur-durrr"

 

Seems notch jetties are not new to New Jersey, what I've learned studying ACOE for over 2 years their decisions are "science' based so some where in ACOE, either Army Corp ERDC (Vicksburg Laboratory) and ACOE New York District are EIS's and monitoring studies of notched jetties. If these studies could be found hoping some link within them might have included "notching" effects on sand bar formation and wave action for recreational users other than continuity of migration of sand through the groins.

I don't have a "dog in this fight" as its not my back yard while its positive or negative affects and outcome would be beneficial to other surfers if this ever occurs locally. So maybe one of you Jersy guys or gals might want to E-mail New York Region ACOE Project Manager Jenifer Thalhauser Jenifer.E.Thalhauser@usace.army.mil. if they would send you their ACOE ERDC studies on notched jetties and follow up monitoring on previously completed NJ groins would be extremely helpful prior to the end of the comment period.

 

Save the Wave: Beachscape data

One way to have science on your side when confronting governmental and private interests who seem to have a revisionist theory on beach dredge and fill projects and their effects: Beachscape data. Have volunteers take photos and measurements of the dune and the high tide line every six months on every stretch of beach that is surfable. That way in several years you can pull out photos and data to prove your point without having fake data shoved down your throat. You establish a data base that claims surf spots as the natural resources that they are. That establishes stakeholders rights, user access, dune protection, etc. Surfrider Foundation has a turn key Beachscape kit available.

The more scientific data, and the more people who make noise about the data, the better your chances of stopping this type of project on a local grassroots level. Best of luck. Save the Wave!

 

Yes, but those beaches are a completely different beach profile than Deal. Deal has very deep water and much longer jetties. When they notch and fill it will be more like Sea Bright and Monmouth Beach, steep drop offs into deep water=shore pound. Those breaks were destroyed for 10 years plus, until Sandy.
And Belmar and Spring Lake did suck for several years post notching/filling. They are finally breaking good again (not good as pre notch/fill in my opinion), just in time for more sand to be pumped.

 

where are you getting your info that its "deeper off deal" then belmar?

I'll concede that the beaches there are more "cliff/bluff" like then farther south but that's more a result of coastal development then natural erosion.

post those pictures of deal "100 years ago" so we can compare.

 

thank you for saying this. too many people just blindly say "dredging is bad" without having a shred of data/science to back it up.

 

The thesis of this project is continue erosion control of completed beach fill projects to allow long shore drift of sand to migrate through the groins vs. collecting on the up drift side of the jetty depriving the down drift beach. The question rolling around between my ears reading Jersy posts after beach fills the sand bars/waves around the groins take about 2 years to come back so do or will these "notches" impede that natural occurrence? So once they remove the stone they're NOT going to put them back. I just read a NJ ACOE study of jetty maintenance and beach fill study of its affects on fin fish and surveyed nearly 2000 fishermen for their feedback of project affects. The sad thing, our recreational use of the ocean is not a bleep on their radar, that's our fault.

I'm sure ACOE has the science, but If ACOE has NOT studied notching affects nor monitored existing notch groins then from my chair that's a legitimate "rebuttal" if they can not validate the project will have NO impact on surfing. Jerzy crew certainly within their right to challenge ACOE to support their actions as a stakeholder to seek further information.
