If you live in LA you'll need to go over at least one highway.

Edit: ITT many Americans telling me of how walkable and great their towns are. I'm happy for you but comrades, I've been to the US once and that was on a trip I won in high school so don't expect me to know the zoning plan of Providence, Wisconsin Pop. 235'489. I don't really care how lovely your city with two buslines is. For every Seattle or Chicago there are 34 Cincinnatis, Houstons and Las Vagases and approx. 234 exurbs and suburbs.
