<br />11/15/24 (P:\M-S\RWC2101.04 Docktown CE\PRODUCTS\Docktown_CEMemo_20241115.docx) 18 <br />General Order would be implemented to minimize the risk of spills or accidental discharge of <br />hazardous materials during deconstruction activities. Such measures include preparation and <br />implementation of an emergency spill and containment plan, and implementation of general <br />site management practices to protect water quality. With implementation of these measures, <br />impacts related to hazards and hazardous materials would be less than significant. <br />Hydrology and Water Quality.As described above, the proposed project would be subject to <br />regulation by the Corps under Section 10 of the Rivers and Harbors Act and would require a <br />Corps NWP No. 22: Removal of Vessels. Because NWP 22 is conditionally certified, the proposed <br />project would not be required to obtain a separate individual water quality certification from <br />the San Francisco Bay Regional Water Quality Control Board. However, the proposed project <br />would be required to submit a Notice of Intent (NOI) and application fee to the San Francisco <br />Bay Regional Water Quality Control Board, as required by the conditions of the General Order <br />for conditionally certified NWPs. The NOI would identify the proposed project’s receiving waters <br />(i.e. Redwood Creek) and beneficial uses of receiving waters, as listed in the San Francisco Bay <br />Basin Regional Water Quality Control Plan (Basin Plan). In addition, the proposed project would <br />be subject to the General Order’s terms and conditions, which include the implementation of <br />Construction Conditions, as applicable and as detailed in Section VI. Conditions of the General <br />Order, in order to protect water quality during construction. Therefore, the proposed project <br />would not impact surface water quality. <br />Groundwater dewatering or extraction would not be required as part of deconstruction <br />activities because activities would be limited to removal of the existing floating dock and <br />associated utilities; no excavation or in-water work is required. <br />The proposed project would remove impervious surface areas and structures associated with <br />the existing floating dock, which would result in beneficial impacts to water quality as it would <br />remove existing above-water structures that currently contribute to the degradation of water <br />quality in Redwood Creek. Further, the proposed project would be required to comply with <br />Chapter 27A of the City’s Municipal Code which requires a written permit from the City Engineer <br />for the removal of the dock to ensure that deconstruction activities do not impact the quality of <br />Redwood Creek. In accordance with Section 27A.10. of the City’s Municipal Code, and as <br />described in the Project Description, the City will be required to provide an NOI, comply with, <br />and undertake all activities as required under the General Order. <br />Additionally, the proposed deconstruction activities and methods that would be utilized by City <br />and its contractor would minimize the effects of the proposed project on federally listed species <br />and their habitat and to protect water quality in Redwood Creek. <br />Noise.Deconstruction activities would result in minimal short-term noise impacts on nearby <br />sensitive receptors. As described above, above-water facilities, including the existing floating <br />dock and associated utilities would be removed using portable hand tools to minimize noise <br />associated with de-construction activities. Material would then be transported by boat to the <br />existing small watercraft launch and loaded on a dump truck for transport to the City’s <br />Corporation Yard and then on to the Ox Mountain Landfill. <br />6.G. - Page 22 of 45 <br />200
