read moreTo the Chief of Police Santa CruzYour action to patrol the Harvey West Park has had a very positive effect on for all of us who live and work in that section of Santa Cruz. Not only are the undesirables keeping a lower profile, the drug activity seems to be obvious. The area in general is much cleaner, les debris and trash along the RR tracks and in and around the streets.
