Question Sign Post Structure

I have a customer that has an LED sign board (13ft wide x 8ft tall) and the sign is 23ft from the ground up to the top of the LED board. The customer got approved to go 33ft (10ft taller) by the city. So my question is, does anyone know a sign engineer that knows pole strength and wind load? I'm on the coast in Gulfport, MS. and can't find anyone around here......

Thanks guys, Yes we are Licensed Contractors and our sign shop is a division of the company and can tackle a big project like that but not to often do we take on projects like this. But sign height, wind load is a different story compared to building code. The pole now is a 14 to 12 inch tapered pole mounted on a concrete footing but the one major factor is, can the existing pole be added to or would a new pole be needed along with foundation. Taking the existing sign up another 10 ft. see attached photos....

 

Right!...........Your absolute correct. It was put in before Katrina for sure, they had another sign co. install the LED board and they cut off about 4ft of the original pole. When they installed the new LED. that claim it was to heavy for the existing pole and did not tell the owner they were cutting off 4 ft. the owner was pissed, not to mention he paid them up front and they will not fix it. Anyways thanks for your help, I contacted https://yjinc.com see what they say......

 

Rick, the city has nothing. Come to find out it was a (under the table political job) non permitted job when it was originally installed. The city has nothing on record. But no, the sign was originally 25ft tall, then Lightning Fast Signs chopped off 6ft. of the top of the original pole. According to them, the existing pole wouldn't hold their new LED board they installed. LFS did not tell the owner they had to chop off 6ft. thus putting the sign below the tree line. They butchered the entire job but won't go into that...........Nonetheless we are now instead going to remove the new LED board, abandon the now shortened pole and moving the sign 6ft east and installing a new footing and 12" pole going back to 30tf tall....(engineered by Nationwide Sign Engineering). I am a licensed builder / sign shop in three states but when doing jobs like this we always get an Engineering Co sealed prints. The safety and liability is a huge factor. I originally asked, does anyone know a sign engineer because the one we used retired.
