Ideas to define property line where ours blurs into neighbors'.
We have a slim wedge of land along our cement driveway, that literally blends into the next door neighbor's front yard. They have untended plants, bark. Our strip is also barked but neater, weed free. We'd like to define the property line, so that it doesn't appear as one shared area, or seem that our property ends at our driveway edge. There is also a problem with many utility lines passing under the area--gas, water, electiricity, even cable TV line, so digging is virtually impossible for a fence footing, and anyway, the city won't allow a fence higher than three feet. Low rock wall? Other fairly simple and not too expensive Ideas??
