My question involves an easement in the state of:Pennsylvania.
There is a common driveway for the residents of one block of homes, with roads on both ends(13 homes). We have a elementary school one block from the properties.
A resident outside of this block insists he has the 'permission' to use our common driveway as a walkway because he was given that permission from an owner (one of the 13) who lives at the end of the block-this non-resident walks through most all our properties to get to this resident's home, then cuts across her property to the street to get to his home. The fact that i, nor the other 12 property owners of the driveway have agreed to this daily use of the driveway has no effect on this person-I and the others are concerned about the liability we might incur based on the blanket 'permission' given this non-resident and their child (who has a tendency to wander off the driveway, ahead and behind the adult). In addition, there is the fact that the driveway has been posted for over 10 years, on both ends: Private property, No trespassing, no thru-traffic.
The residents rarely use this for foot traffic-it is actually pretty busy with vehicular activity, hence our concern about liability. We often have high school students use this as a short-cut illegally (the high school is 1/4 of a mile away) and they can cut through pretty fast-so it is not necessarily a safe place for foot passage. Neighbors park out of the way of the actual driveway,, but can and do back out of parking spaces-potential for injuring someone who does not belong there by our way of thinking. We think this resident does not have the right to blanketly grant someone the use of all properties for this purpose. Please advise, and thanks.
