Noise, trucks and access around the 606 block.

Bellevue's current construction-noise rules allow construction sound from 7 a.m. to 8 p.m. Monday through Friday and from 8 a.m. to 6 p.m. on Saturdays that are not legal holidays. Construction-site noise is not allowed on Sundays or legal holidays under the standard exemption.

Those are noise limits, not a promise that work will fill every allowed hour. The city can issue an expanded-hours noise permit for defined circumstances such as transportation mitigation, site stabilization, essential public work or emergencies. Police receive the city's list of active expanded-hours permits before responding to a complaint.

Bellevue directs construction-noise complaints to the Police non-emergency line at (425) 577-5656. The city says an officer may order the noise-producing activity stopped when it is outside an approved window and clearly audible across a property boundary or at least 75 feet from its source.

Parking, staging, hauling or construction activity in the public right of way requires City of Bellevue approval. A Commercial Right-of-Way Use permit includes a Traffic Control Plan showing lane and sidewalk closures, flagging, temporary signs and how people move around the work.

Bellevue's standard conditions preserve access to neighboring homes and businesses and generally prevent both sidewalks on the same block from closing at once unless a legal crossing is provided. Conditions can vary by permit, so the approved traffic-control plan — not a general project rendering — governs a particular closure.

The city's Traffic Advisories page is the public place to check current lane closures and detours. The Onni 606 permit ledger on this site tracks the project filings, but it is not a real-time traffic-control notice.

The project's 2019 environmental checklist estimates approximately 356,853 cubic yards of excavation. The filing does not convert that volume into truck trips. At roughly 10–18 cubic yards per loaded truck, this site's independent planning range is about 20,000–36,000 loaded truckloads over the life of the dig; it is an order-of-magnitude estimate, not an Onni or City forecast.

The site fronts 106th Avenue NE, but 106th is not one of Bellevue's designated truck routes. City code confines large trucks and hazardous cargo to the highway system or authorized routes; on this side of Downtown, 108th and 112th Avenues NE are the nearby designated north–south routes. A project-specific Traffic Control Plan will determine the approved connection from the block to that network.

Truck activity will not be uniform across the roughly five-year build. The most concentrated hauling belongs to the mass-excavation phase; concrete placement, tower structure, enclosure and interior work create different street patterns later.

Washington Ecology's August 13, 2026 contained-in determination establishes a separate disposal stream for 21,250 tons of PCE-contaminated soil within mapped excavation limits. That specific 2026 scope is distinct from the cleanup plan's earlier approximate estimate of 17,500 tons, and neither figure is the project's total excavation volume.

The determination requires truck beds and roll-off bins carrying CID soil to be plastic-lined and covered, with no standing water. The soil cannot be mixed with other material and must go directly to a permitted solid-waste landfill or transfer station; a trained transporter must manage it protectively. Ecology's letter does not identify the receiving landfill, and it sets handling rules rather than a public haul route.

Onni or TRC must give Ecology at least five days' notice before removal and file itemized monthly shipment tables beginning August 31, 2026. The tables must identify shipment dates, weights, cumulative tonnage, percent removed, and the landfill name and location. Disposal under the determination ends April 30, 2027, with signed receipts or a disposal certificate due May 31, 2027.

The environmental record commits the project to Puget Sound Clean Air Agency dust rules, sprinklering during demolition, reduced equipment idling and a Temporary Erosion and Sedimentation Control plan. Contaminated soil is handled through an independent cleanup enrolled in Ecology's Expedited Voluntary Cleanup Program for technical review, with the additional August 2026 CID transport controls described above.

Bellevue marked a July 14, 2026 erosion-control inspection under the issued early-grading permit Partial with Corrections and directed the installation of catch-basin inserts along 106th Avenue NE. A second inspection on July 20 was logged as Ongoing. At a July 28 job conference, the inspector directed crews to maintain a mechanical street sweeper while exporting soils—the first city entry explicitly documenting soil leaving the block. The note does not identify the soil's destination or contamination classification, so it cannot be retroactively linked to the August 13 CID; it also is not approval of the full excavation. Public records checked through August 23 do not name the CID landfill.

As of August 24, 2026, The most recent stable, dated visual evidence synthesized here is a July 21 high-resolution photograph. It shows the former buildings and most surface slab gone, with excavators and a tracked dozer across a broad, shallow, graded area.

The pit conveyors' Revision 1 electrical review and two podium utility reviews were approved August 24, but both permits remain Pending. Revision 15 of the shoring permit remains in structural and geotechnical review. Ecology's August 13 soil-disposal decision is not a final cleanup decision. The next legal phase change requires the applicable shoring, full-grading and below-grade approvals. Beam-haul and pit-conveyor filings are supporting mobilization records, not proof that those gates have cleared. The live camera and permit ledger are the best ways to distinguish a visible change from a legal phase change.
