The /PD overlay zone applies to all property where /PD is indicated on the Eugene overlay zone map, or when the PUD process is required by an adopted refinement plan. The PUD process may also be used at the request of the property owner. The provisions of the /PD overlay zone supplement those of the applicable base zone or special area zone. Where the overlay zone and base zone or special area zone provisions conflict, the more restrictive requirement applies. Within the /PD overlay zone, applications for development permits shall not be accepted by the city for development until the development is approved according to the PUD procedures beginning at EC 9.8300 Purpose of Planned Unit Development.
