City of Sacramento, Department of Utilities Initial Study & Mitigated Negative Declaration 1 EXECUTIVE SUMMARY Under the California Environmental Quality Act, the lead agency for this Project (The City of Sacramento Department of Utilities) has prepared a Mitigated Negative Declaration, along with an Initial Study for the Routine Maintenance of Stream Channels (Project). The purpose of this document is to investigate potential impacts the Project may have on the environment. Impacts of the Project may be classified as: Potentially Significant Impact, Less Than Significant with Mitigation Incorporated, Less Than Significant Impact, or No Impact. The Lead Agency has determined that the Project would not result in significant or potentially significant impacts. The content and format of this document meets the standards of the California Environmental Quality Act (CEQA). A description of the Project’s environmental and regulatory setting, and a description of the proposed activities are included in this document. The initial study is guided by an environmental checklist, which examines key aspects of 18 environmental resource factors. The impact to each aspect is classified as described above, and a response justifying the classification is provided. Where necessary, Project specific mitigation measures are prescribed to reduce impacts that are not otherwise mitigated by the observance of existing laws, regulations, policies, or permit conditions. The Project would not result in impacts to Agriculture Resources, Land Use Planning, Mineral Resources, Population and Housing, Public Services, Recreation, Transportation/Traffic, or Utilities and Service Systems. By adherence to existing standard operating procedures and/or best management practices; through compliance with existing laws, regulations, or permit conditions; or through the adoption of Project specific mitigation measures, the Project would result in less than significant impacts to Aesthetics, Air Quality, Biological Resources, Cultural Resources, Geology and Soil, Greenhouse Gas Emissions, Hazards and Hazardous Materials, Hydrology and Water Quality, and Noise. The Project would not result in significant impacts to environmental resource factors reviewed as part of the initial study. Revision Date: January 13, 2016 Page 4 Blankinship & Associates, Inc.
