Do you currently own the property that would be affected by the roundabout? If yes, you need to immediately march down to the local city hall and county courthouse and raise all holy **** over this issue. Best to hire legal council that specializes in fighting ‘eminent domain’ takings. Contact your State Legislator/Assemblyman and State Senator that represents your district, and rattle their ears. You need to be proactive on this, the dirty rotten scoundrels in government that will benefit from this would sooner pee in your cereal, than listen to a citizen. If this is worth fighting for, it’s worth fighting dirty for. Dig into the past of the gooberment officials involved, 8x10 glossy’s are a powerful weapon.
