As a NJ resident who has had a simlar issue with the NJDOT & another govermental authority, I believe that this situuation is just stupidity and sloppy/no oversight by the supervisors in charge and/or the ones who drew tthee plans for the project.
With that said, it took me 9 months to resolve one issue and 6 moths the other. I hope my isight will be of use to you.
Start by calling the DOT and get the name and or project # of this work along with the name of the engineer in charge and the person in charge of over seeing that depratment at the DOT.
At tthat point: STOP ALL VERBAL COMMUNICATION WITH THE DOT.
All further communications need to be IN WRITING AND SENT VIA CERTIFIED MAIL WITH A RETURN RECEIPT. this is critical. In the initial letter, include a drop dead time frame for a reply, such as 2 weeks. [they will likely not be able to do so. DO NOT THREATEN COURT.
While you are waiting for the mails, you need to esttablish the extent of your damages. If you have fotos of the area involved prior to the destruction get them together and made large by a foto studio.
Get several estimates from landscapers in the area. Include the name of plus the approx. age, & size of the lost vegeatattion. Get high end ones and a couple of mid range ones.
It will cost you some $. These fees are recoverable in your suit.
If under 3000.00 file in small claims court. If over 3, but under 15,000.00 then file in Special Civil [Superior] Court.
You willl need to know a dollar figure for your loss...not to be in a better position,but to be in the same way that they foundyou before the event. Do this about 2 weeks from the sending of the first letter...it will take many weeks to get a court date.
If the DOT calls you listen politely, but close all conversations with a request for their reply in writing....DO NOT ....EVER rely on anything verbal from them.
Keep a log of all communications, written and verbal.
Do not trust their workers or contractors, they will do crappy work. The State employess & their bosses will be resentful, and the outside contractors are the lowest bidder. Never trust any of their repair people to do the right job unsupervised.
This is a big PITA that you will not get any compensation for the ttime and effort that you have t0 put in to get the repairs done right.
Stay on top of them and be prepared to settle the situation out of court. Make sure to get the settlement offer in writing with time deadlines for payment/and or completion of the job.
Don'y ask me how I know about this. ;-/
Perseverance will win the day.
They will BS you if they can. Calm and cool insistence will win the day for youl
Good luck.
