Illegal dumping and yrespassing

[Courtney Henry]

My neighbor is having drainage work done by someone that's not licensed.  That person has dumped bricks in my yard.  I asked him to remove them and he hasnt.  I also questioned why he didn't ask permission to fill a hole on our property.   Filling the hole will benefit my neighbor but they didn't consult with us prior to doing anything on our property.   Should I contact the city or file a police report?
