affected by project implementation. These trees are protected under the Manteca Municipal Code. Disturbance or removal of protected trees would be a potentially significant impact. IMPACT Terrestrial Biological Resources—Impacts on Sensitive Habitats, Including Jurisdictional Waters of the 4.5-10 United States. Implementation of the project could result in fill or reconfiguration of less than 1 acre of potentially jurisdictional waters of the United States, including drainage canals and the San Joaquin River, and associated freshwater marsh and riparian habitat. This impact would be potentially significant. The proposed wastewater collection system and effluent outfall pipeline alignments cross the French Camp Outlet Canal in two locations. The proposed pipeline alignment for the wastewater collection system west of Airport Way and south of Louise Avenue crosses a tributary of the French Camp Outlet Canal in one location. Freshwater marsh, which is considered a sensitive habitat by regulatory agencies, is present at the wastewater collection system pipeline crossing of the French Camp Outlet Canal just north of SR 120 and east of McKinley Avenue (Exhibit 4.5-2c). In addition,the pipeline alignment for the wastewater collection system closely parallels a tributary of the French Camp Outlet Canal for 2,000 feet west of Airport Way and south of Lathrop Road(Exhibit 4.5-2b). The proposed effluent outfall pipeline is also located very close to a natural depression that supports freshwater marsh, and the outfall structure would be located on the bank of the San Joaquin River. The San Joaquin River is a navigable water of the United States, and the French Camp Outlet Canal and its tributaries, which are tributaries of the San Joaquin River,would likely qualify as jurisdictional waters of the United States. USACE, DFG, and the Central Valley RWQCB are anticipated to assert jurisdiction over these features. Because the project could result in the fill of waters of the United States and impacts on habitat considered sensitive by regulatory agencies,this would be a potentially significant impact. IMPACT Terrestrial Biological Resources—Consistency with an Adopted Habitat Conservation Plan, Natural 4.5-11 Community Conservation Plan, or Other Approved Conservation Plan. Implementation of the proposed project would not conflict with or be inconsistent with the adopted San Joaquin Multi-Species Conservation Plan. This impact would be less than significant. The project area is located within the SJMSCP area, and the SJMSCP was adopted by the City of Manteca on February 5, 2001. Implementation of the proposed project would not conflict with provisions of the SJMWCP and the City would ensure that the project is implemented in a manner that is consistent with the provisions outlined in the SJMSCP. This would be a less-than-significant impact. 4.5.3 MITIGATION MEASURES No mitigation measures are necessary for the following less-than-significant impacts: 4.5-1: Impacts on Common Plants and Wildlife 4.5-5: Impacts on Northwestern Pond Turtle 4.5-7: Impacts on Other Special-Status Birds 4.5-8: Impacts on Wildlife Movement and Nursery Sites 4.5-11: Consistency with an Adopted Habitat Conservation Plan, Natural Community Conservation Plan, or Other Approved Conservation Plan The following mitigation measures are recommended for the significant and potentially significant impacts of Impacts 4.5-2,4.5-3, 4.5-4, 4.5-6,4.5-9, and 4.5-10.
