Yes, NIMBY zoning and a planning process that makes even zoning compliant projects difficult to impossible. The Board of Supervisors are elected from districts instead of city wide. This means they're heavily influenced by neighborhood associations with a vested interest in maintaining the status quo. Throw in the normal, human fear of change and... the result isn't pretty.
