Establishing a new crit course

Hi folks. We have unfortunately lost our local crit course, so there won’t be a local 2020 season for me. Has anyone here scouted, selected, and established a new crit course? Could you share any tips? We have an industrial park but for a multitude of reasons, I wouldn’t consider it desirable. For reference, I live in Spokane which has about 300k people, I would not consider it densely populated, there were four races a year here each with an A, B, C pack, I wouldn’t say any more than 40 racers.
