or

Si tira basura sera multado hasta $235.00 bajo el codigo 46-42 del Municipio de Gilbert y ser expulsados del parque

The context is for a bilingual flyer to be posted in parks on Easter Sunday warning folks they will be cited for littering.

I have a Hispanic employee who disagrees with the online translations, however; when I plug his version into the online translation brackets it comes out not saying the message intended. If it helps to know, our town (Gilbert) is in Arizona

Answer 1

Here is one way to say it:

Se prohibe tirar basura por pena de multa hasta $235.00 bajo del codigo 46-42 del Municipio de Gilbert. Los responsables serán expulsados del parque.
