Pool party needs to be shut down

"I've been trying for five years to shut this down. All summer long there are strangers in and out of the backyard, cars parked all over the street, children's birthday parties, no lifeguard, no CPR equipment and no bathroom access! I've had children urinating on my fence!! Any ideas on how to stop this?

I've contacted DOH, DOB, CB8, etc. just sent to Avella's office today as he seems to be the only one who gets anything done in Queens." - anonymous
