I've noticed that sidewalk gardens tend to proliferate in certain blocks. While many blocks have no sidewalk gardens, just lawn & maybe street trees, other blocks have several extensive plantings near the sidewalk & between the sidewalk & the street. This particular block of 30th Avenue S, on Mt Baker Ridge near Bradner Gardens Park, has at least 5 sidewalk gardens adjacent & directly across the street. This is certainly a boon to passersby. The pictures above belong to 3 of these gardens. Not all of this is what the Seattle Department of Transportation would like to see done in the parking strip. They insist that plants be kept to no more than 3 feet in height for visibility & traffic safety. (Trees are the exception to this rule, but require permits.) In my opinion, it is better to plant shrubs that don't grow much more than 3 feet tall, especially on a corner, where they will certainly block views of traffic.
