Arroyo Grande releases 13-year pavement schedule after E24 sales-tax measure; aims to raise average PCI to 70

At the April 22 Arroyo Grande City Council meeting, City Engineer Shannon Sweeney outlined a 13-year pavement management program intended to bring the city's average Pavement Condition Index (PCI) from about 57 toward a target of 70.

Sweeney told the council the city now maintains about 68 centerline miles of streets and has paved roughly 16–17 miles (about 25% of the system) over the past two years.

Using a neighborhood-grouping approach and a mix of treatments informed by deflection testing, staff produced a 13-year schedule (Attachment 1 to the staff report) that includes every street except three segments that require separate engineering solutions (Hardin off…
