City of Redwood City, Public Works Division Initial Study & Mitigated Negative Declaration <br />Document Date: October 15, 2015 <br />Revision Date: January 25, 2016 Page 56 Blankinship & Associates, Inc. <br /> <br />3.18 Mandatory Findings of Significance <br /> <br /> Potentially <br />Significant <br />Impact <br />Potentially <br />Significant <br />Unless <br />Mitigation <br />Incorporated <br />Less Than <br />Significant <br />Impact <br />No Impact <br /> <br />a) Does the project have the <br />potential to degrade the quality of <br />the environment, substantially <br />reduce the habitat of a fish or <br />wildlife species, cause a fish or <br />wildlife population to drop below <br />self-sustaining levels, threaten to <br />eliminate a plant or animal <br />community, reduce the number or <br />restrict the range of a rare or <br />endangered plant or animal, or <br />eliminate important examples of <br />the major periods of California <br />history or prehistory? <br /> <br /> <br />b) Does the project have impacts <br />that are individually limited, but <br />cumulatively considerable? <br />(“Cumulatively considerable” <br />means that the incremental <br />effects of a project are <br />considerable when viewed in <br />connection with the effects of past <br />projects, the effects of other <br />current projects, and the effects of <br />probable future projects)? <br /> <br /> <br />c) Does the project have <br />environmental effects which will <br />cause substantial adverse effects <br />on human beings, either directly <br />or indirectly? <br /> <br /> <br />Item a): Potentially Significant Unless Mitigation Incorporated. The Project involves the <br />use of copper-based aquatic herbicides introduced into the Lagoon at concentrations that may <br />temporarily exceed SSOs set for the Lower San Francisco Bay. Significant evidence <br />suggests that when used according to label directions by qualified personnel, any SSO <br />exceedance will likely be short-term and impacts of these aquatic herbicides are less than <br />significant. <br /> <br />However, the City or contractor will implement mitigation (HWQ-1) to reduce any potential <br />impacts to less than a significant level. <br /> <br /> Although copper containing aquatic herbicides are a hazardous material, under the standard <br />6.3.A. - Page 64
