For all buildings with frontage along Palm Avenue, including those with multiple-family dwelling units, "active commercial uses" as defined in Chapter 19.05 are required to be provided at a minimum of sixty percent of each building's ground floor lineal footage, have direct pedestrian access from the Palm Avenue sidewalk or a plaza, and have a minimum building depth of twenty-five feet. The remaining forty percent must either be primarily related to the commercial use, such as parking, access, or other non-active commercial purpose or, if related to non-commercial use, must be designed either to encourage and promote pedestrian activity or to visually screen required on-site parking.
