Neighbors urge more study of lighting, traffic and construction after Planning Commission reviews recirculated EIR for Sunset Blvd project

Staff presented the recirculated draft environmental impact report (RDEIR) for a proposed five‑story commercial office building at 9160–9176 Sunset Boulevard that includes two integrated full‑motion animated billboards and subterranean parking. The RDEIR replaces 10 sections of the original DEIR and adds new studies on digital lighting, transportation safety and biological impacts; updated CalEEMod modeling and a revised noise study were also included. Staff said the revised analyses found no new significant operational air quality, greenhouse gas or energy impacts, but that nighttime construction noise and vibration were identified as significant and unavoidable despite proposed mitigation.

The public comment period on the RDEIR was extended to April 27, 2026. Dozens of residents — especially from Sierra Towers and the Carrollwood condominiums across from the site — urged the commission and staff to study cumulative lighting and glare effects, to model light intrusion at elevated residential elevations (not just ground level), and to reconsider any allowed nighttime construction. Sierra Towers residents emphasized potential health and sleep impacts from bright animated displays and warned of diminished residential livability and property values if large animated billboards face residential units.

Speakers asked for stronger, enforceable mitigation measures including (at a minimum) moving digital faces away from residential properties or eliminating the billboard component, requiring completion of off‑site intersection improvements prior to issuance of building permits, and prohibiting nighttime construction. Several speakers also questioned whether traffic studies used pandemic‑era counts and urged updated data for existing conditions.

Staff and the RDEIR authors said new lighting and biological assessments conclude the proposed signage would not exceed applicable lighting thresholds and that transportation memos and trip assessments were updated; staff said comments received will be addressed in the final EIR. The RDEIR proposes mitigation for daytime construction noise and driveway access; the authors flagged temporary nighttime construction noise and vibration as significant and unavoidable.

Commissioners asked specific follow‑up questions about lighting measurement methodology (vertical plane modeling at billboard elevation), whether Sierra Towers and Carrollwood were modeled at occupant elevations, the adequacy of traffic mitigation ("Keep Clear" signage), and the feasibility of prohibiting nighttime construction. Staff said they would collect public comments through the revised comment period and work with consultants to prepare responses for the final EIR; the final EIR and project hearings will return to the Planning Commission and then to City Council for a decision on the project.

The record shows strong neighborhood opposition to the billboard component and requests for additional mitigation and study before any entitlements move forward.
