I would imagine it's roughly 36", but it would be easy to check with a phone call to your local building inspection and permit issuer.
30" is the prescribed depth for water lines by City Building Department. However, with all things engineering, this is not an absolute answer. This depth is most likely based on a 50 year probability of reoccurance. So frost may go lower but it does not happen often and it probably would not be much lower than 30".
ZERO miles. There is only one street between the two cities, and it is named "State Line Road."
There is a Kansas City in Kansas, as well in Missouri. Multiple states have the same names of cities. Like twin cities in other parts of the country Kansas City Missouri and Kansas City Kansas are right next to each other, unlike most twin cities the two aren't divided by a river but only by a state line. The things that one thinks of when they think of the dominate of two cities are all located in Kansas City Mo. The national sports teams, the major art venues and dominate business district.

The city of "Kansas City" is divided in about half by the states of Kansas and Missouri. Some maps show two cities (two dots) on either side of the state's borders. The US Postal service provides zip codes for Kansas City KS and Kansas City MO. The capitol of Kansas is Topeka. Since a city is always a corporation, of sorts, of a State, the best way to know which State Kansas City belongs to is to call the executive office in Kansas City and ask which State they have legal allegience to. I spoke to someone on line who was in Kansas City and she said there are two Kansas Cities, one in Kansas and one in Missouri. They both have a "city hall". This setup may be a lot like St. Louis. So the answer is there are two Kansas Cities, one in Kansas and one in Missouri and they are physically divided by the state border.
