These two intersections have crosswalks that were just painted (thanks Oakland!). However, this is still not enough for drivers to notice that it is indeed a crosswalk. There is a senior building with entrances and exits on both 21st and 22nd and I have seen countless numbers of these people just miss being hit by cars at both of these intersections. Please put up a crosswalk sign and zebra stripes or reflectors on the street. This is a true safety matter!
