The project has been granted a Notice of Exemption based on categorical exemptions under the California Code of Regulations, indicating that the alterations are minor with no significant environmental impact. All work must be performed in accordance with the specifications detailed in the notification dated August 25, 2025. The project is located at Assessor's Parcel Number 033-172-46, specifically at latitude 39.7210 N and longitude 123.3351 W.
