Given how many houses there are and how expensive they are, I'd think there's quite a chunk of change coming in - property taxes, sales taxes, permits, etc. - so I think financially it should be enough, but I haven't seen this really being addressed. And building new roads when the existing ones are already choking up would be really tough, they need to do it now before all those new houses are fully occupied. Doesn't look like they realize it, at least from my vantage point (I of course have no inside info, maybe they're working on it day and night...)
