So while there is a plethora of words regarding features of urban planning in Latin, is there an actual term or phrase for the act of planning a city? "Urbs designans" and "inventio urbica" seem like poor fits to me, and I feel like a culture with such a civil engineering bent would have had a dedicated word for the urban planning field, but I just can't find any.
In addition, within the field, was there a term for the city grid? I am aware of the terms for the various streets, buildings, etc., but "reticulum urbicum" strikes me as incorrect, as I was under the impression "reticulum" meant more of a "net" than a "grid," and "cancellus" seems to be more associated with literal bars than cities. Again, I find it hard to believe, given the nature of the Romans, that they would not have had a word for a city grid, but I simply can't seem to find it.
