To those of you who are interested in extending a dock or placing a new dock in coastal waters under the general permitting process in Connecticut, you need to know that submerged aquatic vegetation plays a key role in the limits of docking facilities. Submerged aquatic vegetation typically becomes visible when it first emerges early in the summer. Generally, the beginning of June or so.

Submerged aquatic vegetation also defoliates in the fall, typically around the end of September.

If there is any dock project being planned, it would be advisable, in fact imperative, to get your project underway in the immediate future. If the submerged aquatic vegetation defoliates or begins the defoliation process before your submerged aquatic vegetation survey is complete, the lack of credible evidence relating to submerged aquatic vegetation may preclude you from making an application until June or July of the following year.

What our clients say about us:

Dear Keith:

A long overdue compliment to you and your staff. Docko is an amazing orginization. Not only did you take on a difficult task in providing us with a aesthetically pleasing deep water dock but you provided us with safety in your design when it wasn't part of the play book. You and Docko went the extra mile in presenting Marine Wave studies and in creating evidence so that our dock approval would provide convenience, practicality and safety rolled into one tidy package.

Everyone on your team handles themselves professionally and I would like to suggest that anyone looking for a dock permit dial the number for Docko Immediately !!!!!

Thank you,

Evan and Ann Carpenter


Barb and I went through almost 6 hours of deposition. My head is still pounding. I will NEVER understand what we are disputing can consume 36 hours of peoples’ lives without moving the world to a better place.

But I did describe your work (which arrived right on time). Their counsel is not inclined mathematically or with an inclining toward engineering. We are going to have to simplicity the math. But the point you made with me last night was made with them. They got the point that there is no impedance.

They were so amazed you thought to put the presentation together based on your impressions from the Oct trial. Great initiative.

Thank you, Keith, for everything. We couldn’t be in better hands!!!!! All the best, my friend,

Donald E. Foley

Dear Keith:

We’ve been remiss in not thanking you earlier for all your help in designing and building our beautiful dock. We would not have been able to do it without you.

We knew it would be a difficult process. In addition to the normal permitting barriers, we had to contend with extra outside attention and opposition. Not only did you handle the situation with grace and dignity, but you diffused many issues with knowledge. Who else knows not only the ins and outs of permitting and engineering, but also the players and personalities, who built which dock and when, the historical changing geography and riparian lines of the area, property rights and mean water marks, historical uses of waterways and what really is located under the harbor, etc. The breadth of knowledge is incredible.

Your advice on design and materials was spot-on. We didn’t have to worry about a thing, because you were there to make sure everything was done correctly. Our dock is beautiful and tasteful, and fitting for the area. The contractors were skilled artisans and the workmanship is exceptional. We have received many compliments on the dock, some from passing boaters. More importantly, we love it and will enjoy it for many years to come.

Again, we couldn’t have done it without you. I don’t know where else we could have found that unique combination of expertise that made it all possible. Thanks to you, your firm, and all your colleagues for such a fine job.

Frank and Laura Mastrapasqua

Dear Keith:

Thanks so very much for your most gracious letter. We will certainly agree that the “situation” was sometimes stressful, but NEVER, in our view because of you, your firm, or your work on our behalf. We always felt that you had our best interests, and more importantly, the best interests of the property itself at the center of the dialogue with the state. Should we expect some sort of “close-out” from the DEEP?

With or without the trees, the view is quite stunning, and we are ALWAYS glad to walk in the front door to see it again !

It was a genuine please to work with you.

With best personal regards,

David and Betsy Sams

The Mystic Harbor Management Commission wishes to express their sincere appreciation for the contribution you made to laying out the mooring grid for the turning basin. If it hadn’t been for your advice and the work by Bill Cotter, we would not have been able to have all the moorings in place by the date needed. We also want to recognize and thank Bill for responding so quickly and professionally as our requirements kept changing. (Click here for original pdf)

David Carreau - Chairman, Mystic Harbor Management Commission

I've been getting your emails and I got Keith's voicemail yesterday giving me the verbal update. As always, I'm constantly impressed with your firm's ability to follow through and continue to get results.   Thanks so much for all your work and keep me posted and things develop.

Sapia Builders, CT

I was doing the planning to get the family together for “dock day” next month to get the dock in at 104 Latimer Point. I thought about how difficult the permit process is and how we never would have been successful without the help of Docko (Keith, Bill, and Joan). Being able to re-use the same dock that we were forced to remove by the DEP is especially pleasing, as it was designed to overcome some of the natural obstacles (rocks, low water) and still be constructed so that we can remove it for the winter. Thank you again for your professionalism, and patience with us in some trying circumstances.

I knew when Tammy and I told Brian to go to you we would get something professional and timely. Thank you both very much and enjoy the short holiday., Niantic, CT

Giant’s Neck Beach in Niantic Connecticut has, like so many beaches along the Connecticut shoreline, suffered from a slow erosion due to varying effects ranging from a slow but constant littoral drift, storm patterns, and the steadily rising of the level of the sea due to global warming, whether caused by man or the natural cycles of nature or by a combination of both.

The sand on the beach at Giant’s Neck has tended to shift westward along its length only to ten be washed seaward by a stream which enters the Long Island Sound forming a sand bar at its west end.  Many possible solutions for restoration of our beach were discussed with several resources.  The Giant’s Neck Beach Association finally decided to contract with Docko, Incorporated of Mystic CT., experts in all aspects of recreational and commercial marine design and construction, to help us with our problem. Their solution for our specific erosion issue was to harvest sand from this offshore sand deposit and redistribute it along the entire length of the beach. 

The bottom line is that with Docko leading the way with mapping and engineering insight as well as administrative expertise in dealing with the DEEP, The state department of Fisheries and other government bodies, we were able to secure the required permitting and have begun our projected 5 year plan for beach restoration.  Keith Neilson, president of Docko, and his entire staff have helped make a process, which also included review of bids and oversight of the sand harvesting, efficient and painless.  We are very pleased with their efforts and the preliminary results.
