Section 6.2.4. Parking Requirements
A.   Using the Parking Tables
Uses on the parking table match the allowed uses and use groups in Article 59-3. The number of required spaces is based on a metric specific to each use. If the proposed intensity of the use is less than the metric in the tables in Subsections B and C, the baseline minimum is calculated using a fraction of that metric. The number of vehicle parking spaces required also depends upon whether the property is located in or outside of a Parking Lot District or Reduced Parking Area.
