Planned Development Overlay (PRO)
All uses	1. The underlying zoning district standards shall control all standards unless a density bonus is awarded.
	2. The city may award a density bonus for single-family or planned development of up to 15 percent over the underlying district.
	3. Required open space ratios (OSR) may not be reduced by more than 10 percent of that required in the underlying district. An underlying district with an OSR of 0.20 may be reduced to 0.18.
	4. Planned developments shall use the standards of Table 17.40.110(B).
	5. All other lot standards shall be specifically approved and spelled out in the planned redevelopment overlay preliminary plan.
