CEQA Addendum for Amendment to an Approved Map

The project involves a Map Amendment to the Approved Recorded Parcel Map (PM06-030) for APN 057-240-023, located at 23446 Angelina Avenue in Auburn, California. The primary objective is to create a new building envelope for a future residential home on the southern portion of the parcel and to revise the blue oak environmentally sensitive non-disturbance area on Parcel 4. This action is processed under CEQA Section 15164, amending the original Mitigated Negative Declaration (EIS06-039) to ensure that no new significant environmental impacts result from these technical changes. Final approval is subject to the review of the Nevada County Zoning Administrator. Environmental compliance is a critical component of the project, requiring the establishment of Environmentally Sensitive Areas (ESAs) for seasonal streams, ponds, wetlands, and the Bear River floodplain. Construction activities must utilize orange safety netting for delineation and adhere to strict erosion control measures, including the use of weed-free straw fiber rolls and avoiding grading during significant rainfall. Additionally, the Department of Toxic Substances Control (DTSC) has provided guidance regarding historical agricultural contaminants, requiring the analysis of pesticides, organochlorine pesticides, and arsenic. All imported fill material must be tested and documented to ensure it meets screening levels defined in the DTSC Preliminary Endangerment Assessment Guidance Manual.
