Here's the thing: maintenance of existing infrastructure that serves existing residents is almost entirely paid for by astronomical "impact fees" paid by new developments. In the East Bay, 85% of EBMUD's maintenance (not capital!) budget is funded from impact fees. These can be really high. Any new dwelling in the East Bay pays a minimum of $26000 for water capacity and a minimum of $4100 for wastewater capacity. It's a big pyramid scheme and the existing residents better get a clue and permit some new construction, or the public utility districts are going to have to change their strategy and get all that money from annual assessments on existing properties.
