3. Environmental Checklist <br /> <br />San Leandro Treatment Wetland <br />IS/MND <br />3-34 February 2024 <br /> <br />site was part of the San Francisco Bay shoreline. While no distinct geological features are present, <br />there is a potential for buried paleontological resources, such as fossilized plants and animals and <br />their imprints, from previous geological eras. <br />However, the site has undergone significant disturbance and elevation due to fill material from <br />unidentified sources. Consequently, the likelihood of intact paleontological resources being present is <br />low. The grading activities associated with the Proposed Project are confined to the placement and <br />movement of onsite stockpiled soils and imported fill. Therefore, the Proposed Project is expected to <br />have a minimal impact on paleontological resources or unique geological features. <br />Impact Designation: Less than Significant Impact <br />Cumulative Impacts on Geology and Soils <br />The impacts associated with geology and soils are typically localized, with minimal potential for cumulative <br />regional effects. Geological conditions can vary significantly even over short distances, resulting in distinct <br />outcomes in nearby areas. Unless a project substantially modifies the underlying soils and rocks of adjacent <br />projects or heightens the risk of landslides in surrounding regions, its impacts related to geology, soils, and <br />seismic hazards are confined to its location. Consequently, the potential for cumulative impacts concerning <br />these factors is restricted to the site and any immediate neighboring projects. <br />Ongoing maintenance activities occur at Oyster Bay Regional Shoreline, which is not anticipated to affect the <br />local geology, soils, or seismic hazards in the immediate area. Therefore, it is concluded that the Project would <br />not contribute to any cumulative impacts on geology, soils, and seismicity.
