County agrees to immediate speed‑reduction signs and driver‑feedback signs near Google construction; traffic study to determine long‑term fixes

County engineer Andy Wicks updated the board on traffic and safety measures around Pioneer Trail and Wabash Avenue tied to nearby Google construction. Wicks said a partner agreed to install and pay for driver‑feedback signs and that the county will reduce the speed limit on a portion of Pioneer Trail from 40 mph to 35 mph; staff expected signs to be installed that day.

Wicks and other staff said Olsen Engineering had recommended signalizing the intersection of Pioneer and Wabash if truck traffic reaches about 200 trucks per hour, but that current counts did not show that volume. “Olsen's recommendation was if there are 200 trucks an hour, they recommended signalizing the intersection of Pioneer and Wabash,” staff said. The board directed staff to collect updated traffic counts to determine whether a three‑way stop or signal is warranted; staff said stop signs could be installed within a week but preferred a study-based decision to avoid unintended queuing problems.

Public commenters who live near the site told the board that truck traffic and dirt hauling have increased crashes and damaged driveways. One resident said JE Dunn’s contractor told neighbors the dirt-hauling phase could last up to two years and asked who would repair damage to local roads and mailboxes once construction ends. Board members said county plans call for road repairs after construction and encouraged affected residents to continue reporting damage and safety concerns so staff can document impacts.

The board also discussed possible transit adjustments and partners to handle increased visitation during events, and asked staff to coordinate with law enforcement and obtain the updated counts before deciding on permanent traffic control changes.
