This is a backyard that I have been watching for the for the last couple of months as I drive this section of the I-15 freeway. Not a lot has happen here, maybe the 1950’s Ford pick up has moved a tad bit. Still your basic dirt yard landscaping. Another difference with the Coastal Freeway, if a brick wall is to provide some visual/noise seperation between the adjacent houses and the freeway, it would actually block the view of the freeway. As you can see, that is not a requirement for the Inland Empire. Actually I am not sure what this block wall is providing. The freeway noise must be really loud, which is probably why I have seen anyone actually in this back yard.
