Reasons for Exemption
Biological Resources
A review of the California National Diversity Database determined that protected plant species could potentially exist onsite, including Pismo Clarkia. On June 1, 2024 and July 1, 2024, botanical surveys were performed on the project site (McGovern, 2024). These surveys did not identify any special status plant species. Therefore, no impacts to biological resources are anticipated.
Archaeological Resources
A Phase I Archaeology Survey was prepared for this project (CRMS, 2025). In the unlikely event resources are uncovered during grading activities, implementation of County Code Section 22.10.040 (Archaeological Resources) would be required, which states:
A. Construction activities shall cease, and the Department shall be notified so that the extent and location of discovered materials may be recorded by a qualified archaeologist, and disposition of artifacts may be accomplished in accordance with state and federal law.
B. In the event archeological resources are found to include human remains, or in any other case when human remains are discovered during construction, the County Coroner shall be notified in addition to the Department so proper disposition may be accomplished.
Therefore, no impacts to archaeological resources are anticipated.
Other CEQA Issue Areas
In addition, based on the project description, baseline conditions, and analysis of the project’s potential environmental impacts, the project will have less than significant or no impacts relating to the following:
• Aesthetic and Visual Resources
• Agriculture
• Air Quality
• Energy
• Geology and Soils
• Greenhouse Gas Emissions
• Hazards and Hazardous Materials
• Hydrology, Water Quality and Wastewater
Conclusion
It can be seen with certainty that there is no possibility that the activity in question may have a significant effect and the project is exempt from CEQA
