StreetScan finds Auburn roads average a PCI of 70.6; sidewalks score 75.6
Summary
Public works presented a citywide pavement and sidewalk condition survey showing an average pavement condition index of 70.6 across 185 miles scanned and a sidewalk average of 75.6 across 56 miles; staff will use ADT and utility coordination to prioritize next year’s CIP.
Auburn public works staff presented the results Oct. 20 of a citywide pavement and sidewalk condition survey conducted this year by StreetScan, reporting a citywide pavement condition index (PCI) average of 70.6 across 185 miles and a sidewalk average score of 75.6 across 56 miles.
Public works representative Mr. Goyette explained the StreetScan vehicle collected block‑by‑block segment scores. The road-length breakdown: 33 miles rated excellent (86–100), 67 miles good, 50 miles fair, 25 miles poor, 7.3 miles very poor, and about 0.5 mile in serious condition. Sidewalk scoring similarly assigned most segments to good or better, while roughly 2 miles of sidewalk were flagged for near-term attention.
Goyette said the city will not rely on segment scores alone when scheduling work; staff will combine PCI segments with average daily traffic (ADT), coordination with utility replacements (water, sewer, gas) and capital funding availability to determine which streets to rehabilitate, reconstruct or overlay. He also said staff are preparing a more user-friendly street-length list and GIS overlay so councilors — and constituents — can see prioritized segments without having to inspect thousands of individual segment records.
Councilors asked about brick sidewalks in downtown areas and whether there are lower‑cost alternatives that preserve downtown character; staff noted brick replacement is expensive but sometimes necessary for the downtown appearance and safety considerations. Staff also said tree roots, freeze‑thaw action and surface cracking are the most common causes of sidewalk distress.
The council asked for a CIP-ready list that combines StreetScan scores with usage and recommended pavement treatments, and Mr. Goyette said staff will prepare that list for the next budget cycle and explore GIS visualizations to aid constituent inquiries.
