o Pavement Condition Index (PCI) as evaluated by the Public Works Department which assigns a score from 0 to 100 (lower score represents worse pavement condition) based on several factors which determine the structural integrity of existing street pavement.
o Density of existing residential structures with frontage to the street.
o Condition and risk ratings of existing underground city utilities including water mains and wastewater mains.
o Storm Drain Improvements based on recommendations provided by a Professional Engineering Design Consultant under DR1809 (Drainage Study of the Finch Creek Watershed).
