I don't see any obvious contradictions. You can't park 11-1 tuesday due to street cleaning. You can't stop there mon-fri 7:30-16:00 with the exception of 7:30-8 for school business (dropping the kids off). You can park mon-fri between 4 and 6, once per day, per district (to pick up your kids after school), district permits (people who live there, not sure what the 4 means) are exempt.
