Is it really the county's job to arrange for utilities to be installed for a new development?

The county was supposed to set that when the streets were drawn; that's the way it works with the utilities (phone, water, power) as well. The responsibility is either with the county or with the cable company.

Your county draws the streets for new subdivisions???

That's definitely not how it works here. Streets for new subdivisions are drawn out by the developer and paved by the developer.
