And thou shalt gather all the spoil of it into the midst of the broad place thereof, and shall burn with fire the city, and all the spoil thereof every whit, unto the LORD thy God; and it shall be a heap for ever; it shall not be built again.
Sefer HaChinukh
The burning of an enticed city and to kill its people: To burn an enticed city and everything that is in it. And a city of Israel [whose inhabitants] have been enticed by wanton men to leave from under the wings of the Divine Presence, and go after the whims of their hearts to worship idolatry, is called an enticed city. And about this is it stated (Deuteronomy 13:17), "and you shall burn the city with fire, and all of its booty."
Sefer HaChinukh
To not rebuild an enticed city: To not ever rebuild an enticed city. And about this is it stated (Deuteronomy 13:17), "and it shall be an everlasting mound; you shall not build it again."
