Please remove the sawhorse no parking signs in front of Trader Joe's. They are really ugly and they prevent street sweepers from accessing the curb. I'd suggest simply removing them and allowing parking there once again but if the City feels that this prohibition is still warranted, then the area should be red curbed so that this blight can be removed.
More broadly, I recommend extreme caution when considering the placement of signs, bollards, berms, K rail... on city streets. Almost always the placement of these things create more problems than they fix.
