I have seen where some home owners will bring
in some truck loads of top soil and make a hill,
like out closest to the roadside or sidewalk area.
Each design could be of the owners, no set rule..
Some have all the piles into the corner and in the shape of a triangle like, tall in the middle and tapered to the ends, and things planted on them.
Some is one long pile in front and then plantings on top....shrubs,
trees, etc...
The piles of dirt cut down on the sound, give a wee~bit of privacy, and have lovely plantings on it that add beautification to the neighborhood.
I wish I could find a picture, I looked all morning and must not have the right word for the google searches... I thought they were called Burm's...
Anyone know what I'm talkin' about????
