Last summer our neighbor needed to have his septic system replaced. He asked if the trucks could access his yard through our property. It meant the trucks would drive up our driveway and cross about 15 feet of lawn to get to his backyard. He also said he would reseed the lawn if any damage was done. We reluctantly said yes, because we wanted to be good neighbors. He not only reseeded the lawn, but brought in some new gravel for our driveway, which was very kind of him (even though my dh says it was the wrong kind and the driveway is now too loose). Well the problem is now our neighbor uses our driveway all the time--several times a week--and drives across our lawn to access his yard! I'm hoping it's temporary, since he's doing landscaping to replace what was lost last year to the new septic tank. Should I endure, or should I say something to him (he and his wife are deaf so communication is very difficult), or should I do a little landscaping along my driveway so he can't access his yard anymore? There used to be a tree right where he drives, but it died and I never replaced it. I could do that now, along with some more trees I've been wanting to add. Any thoughts?
