Long story short, i have 100% access to do whatever I want with a private parking lot that gets full (~150 spaces) thursday/friday/saturday. the only problem is that the type of people that this parking lot attracts are the drunk hispanic/blacks who go to the trashly clubs near where the parking lot is located. These people are crazy- cops have been called almost every weekend - drug deals - fights - you name it. you DONT want to be in this parking lot at night. currently, they enter the parking lot for free and tailgate/club until the early hours. My family owns the lot and wants them all out because they break signs/bottles/wreak havoc and then we have to send someone to clean it up. it's a business parking lot for a law firm(*family owned biz) and hospital during the day but it is used for free during the night by randoms. The current prospect is just to hire a towing company to deal with it (its free because they tow the cars and charge whoever they towed). I'm looking for alternative methods to monopolize on the situation. The only thing I have thought of is building a small guardhouse and paying someone to sit and collect 5 bucks a car, but the people are so sketchy that i'm afraid they will hurt someone. Anyone have an idea to handle this?
