Aren’t there laws about now allowing a residence or building to be X feet from property lines and roadways? I’d think 7 feet would be too close for them to legal construct the bike path from her front door. Of course, they’ll just declare her house too close to their bike path and demand she tear it down.
Something very similar was done in our town. Usually there’s an 8 foot requirement, but the county essentially planted a bike path right in front of several homes. I don’t know if anyone tried to stop it. That takes money & most folks don’t have the ability for a protracted fight with their local government.
