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
notching the jetties is honestly a smart move if they want to keep those beaches and the million dollar homes on it. there's a good deal of research showing that groins adversely affect the longshore flow of sand/water and cause unnatural errossion. most of those jetties in particular are huge and have a more pronounced effect than smaller groins.
for example look at the beach right to the north of the roosevelt ave access. that beach and the beach immediately to the north have suffered greatly from that large groin.
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.
If they are actually talking about ripping out jetties, then that's completely different concept than notching them. Normally, notching a jetty means creating a low spot somewhere midway along a jetty to allow a bit of sand to flow over the jetty, so some sand reaches the downdrift side of the jetty instead of having to flow all the way around the seaward end of it. How it affects surfing depends on the specifics of the location.
And Erock is right. Jetties and groins are different things. Jetties are at inlets to stabilize the sides of it, groins are similar structures but built in beaches for erosion control, not at inlets for inlet stabilization.
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.

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
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.
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.
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!
