Mixed-Use areas are encouraged where infill and redevelopment reinvestment is desired.  These areas should provide convenient access to higher capacity arterial streets and/or potential transit service.  Desired building heights are typically three stories, or up to five stories where greater development intensity is compatible with surrounding uses.  Various modes of transportation are in proximity, including walking and biking paths.  Defining and activating street edges with buildings is a preferred planning pattern, with Crime Prevention Through Environmental Design (CPTED) principles that apply to the urban design strategy.   Some parcels may be too small or odd-shaped to accommodate desirable mixed use infill development.  This may require property assemblages before mixed use redevelopment is appropriate.
