The City of Denver uses GIS tools like ArcIMS, Geocortex, Accela, and MapIt Denver to manage its marijuana permitting process. Applicants submit paperwork through Accela, which uses spatial alerts to check for proximity to other retailers, schools, and daycares. If approved, GIS generates a notification area and report for a needs and desires hearing. The system streamlines permitting while ensuring compliance with regulations. Future plans include expanding data and customizing Geocortex for this workflow.
