This should be a fairly easy cache; not exactly a P&G, maybe a PW&G (park, walk, and grab). It's located along a bike trail beside a relatively busy road; the area is fairly well traveled by pedestrians at certain times, so patience and stealth may be required. You do not have to move, or remove, any part of the wall to access the cache. Also, you do not need to go on private property, the cache can be easily accessed from the bike path. However, it will likely not be accessible if there is a lot of snow (which has not been a problem the last few years!). The cache only has room for the log, you will need to bring your own writing utensil. Please put the container back in the same location so it will not be spotted by passersby.
Congratulations to BigGriz for being the FTF!
