The City generally seems in favor of supporting ways for residents to get around town by means other than by car. Having accessible sidewalks should be a fundamental part of this effort. Unfortunately, being on foot of any number of streets in the city (Manhattan Ave, Monterey Blvd, and nearly any east/west street east of Valley) means snaking around obstructions and often walking into the street to avoid cars parked in driveways extending well into the sidewalk.
Some cities have provided smartphone-based 311 apps to report violations and make enforcement requests. Perhaps Hermosa Beach should consider something similar. Or at the very least, have parking enforcement step up its enforcement efforts.
After all, what good is a beautiful, walkable beach town if you can't actually walk it?
