They are intentionally raising gas prices and forcing higher CAFE efficiency ratings to force everyone into EVs.

.), the location, depth, and capacity of utilities to service the site - including public utilities (sanitary, storm and water services), franchised utilities (power, gas, cable), capacity of the local streets to accommodate additional traffic from your development...Be sure to find out if there are any specific local ordinances you need to satisfy (possible tree & wetland surveys, together with any necessary tree & landscape or wetland mitigation plans) and whether there are any concerns from municipal departments (e.g. hydrant locations from the fire department, storm inlet and retention requirements, as well as asphalt / concrete road requirements from the engineer), entrance requirements from the road commission (left turn and passing lanes at the site entrance), etc.Once you get past all this you can finally prepare a preliminary site plan and enter the political arena to get preliminary site plan approval, and to address any concessions the board and neighbors want from you to overcome their objections to your development.

Don't give an address, but talk through hypotheticals.It depends town to town and how grumpy the building inspectors are.
