Mayor De Blasio's new plan to install smoking booths in parks, and smoking tents on the beaches, and both structures at other high pedestrian places is implementable, and the City Council is poised to approve his plan.

implementated 

a misuse of the word "implemented", the past participle of implement, which means to put into effect, to apply, to put into action.

I noticed Urban Dictionary had not implementated the word "implementated" yet, so I submitted it. I hope it is implementated now even though grammatically it is incorrect.
