Per the website, it’s to be defined in a future Comp Plan update - “City is in the process of developing a map.”
Kind of surprised that TC-20-21 is already out to public comment, since I’ve been watching for it on the Planning Commission and Text Change Committee agendas but there’s been nothing. Even the 1/25/2022 “Pending Items” status update says that it’s still “drafting.”
