for the wastewater collection system and recycled-water distribution system. In addition to the crops mentioned <br /> above, almond orchards,vineyards, and strawberry fields existed on these adjacent lands. <br /> Annual Grassland <br /> Annual grasslands used for pasture occur in four locations within the project area. Permission to access and walk <br /> areas supporting annual grassland habitat was not obtained. Therefore, annual grassland habitat was observed and <br /> evaluated from a distance during the reconnaissance surveys, and soil survey data pertaining to the annual <br /> grassland areas was reviewed(SCS 1992). The annual grassland present along the proposed pipeline routes for the <br /> wastewater collection system, effluent outfall, and recycled-water distribution system was dominated by <br /> nonnative grasses such as Bermuda grass (Cynodon dactylon), Italian ryegrass(Lolium multiflorum), slender oats <br /> (Avena barbata), and foxtail barley(Hordeum murinum). Most of the soils underlying these annual grassland <br /> areas are very sandy,well drained, and nonsaline,with the impermeable hardpan soil layer,when present,usually <br /> found at a depth of 50-60 inches from the soil surface. Saline soils are present under one area of annual grassland <br /> that is located on the outfall route south of State Route(SR) 120 immediately west of McKinley Avenue. In <br /> addition, an area of ponded water was observed in annual grassland habitat within 30 feet of the proposed <br /> wastewater collection system route approximately 900 feet north of Yosemite Avenue and east of Airport Way. <br /> Drainage Canal, Irrigation Ditch, and Freshwater Marsh Habitat <br /> The proposed pipeline routes for the wastewater collection system, effluent outfall, and recycled-water <br /> distribution system cross or are located immediately adjacent to several canals and irrigation ditches(Exhibits 4.5- <br /> 1,4.5-2a,4.5-2b, and 4.5-2c). Freshwater marsh habitat is present in two of the canals and an irrigation ditch. <br /> Habitat conditions at each of these locations are described below. <br /> South Manteca Trunk Sewer <br /> The proposed wastewater collection system crosses the French Camp Outfall Canal south of the WQCF property <br /> and north of SR 120 (Exhibit 4.5-2c). The French Camp Outfall Canal is a human-made drainage canal and is also <br /> a tributary of the San Joaquin River. Where the proposed wastewater collection system crosses the French Camp <br /> Outfall,the canal averages 30 feet wide at its ordinary high-water mark(OHWM). Water and freshwater marsh <br /> vegetation was present in the channel of the canal at the time of the June 2006 reconnaissance survey. The marsh <br /> was dominated by common tule(Scirpus acutus)and tall flatsedge(Cyperus eragrostis). One large red willow <br /> (Salix laevigata) grew on the bank, and six-petal water primrose (Ludwigia hexapetala)was floating in the open <br /> water of the channel. <br /> North Manteca Trunk Sewer <br /> The proposed wastewater collection system would cross a drainage canal north of Yosemite Avenue and west of <br /> Airport Way(Exhibit 4.5-2a). The crossing is located 1,000 feet east of the confluence of the drainage canal with <br /> the French Camp Outfall Canal. This drainage canal averages 25 feet wide at its OHWM, and water was present <br /> in the channel at the time of the reconnaissance survey. A few wetland species, including common rush(Juncus <br /> effusus),willow smartweed(Polygonum lapathifolium), and tall flatsedge, grew on the banks of the canal at the <br /> proposed crossing point. <br /> Beginning at a point just west of Airport Way and north of the Southern Pacific Railroad tracks,the proposed <br /> wastewater collection system route would be located within 5 feet of a drainage canal for approximately 2,000 <br /> feet(Exhibit 4.5-2b). This canal is also a tributary of the French Camp Outfall Canal and averages 20 feet wide at <br /> its OHWM. Water and dense freshwater marsh vegetation types are present within and along the banks of the <br /> channel including common sedge,tall flatsedge, slender willowherb(Epilobium ciliatum),purpletop vervain <br /> (Verbena bonariensis), and willow smartweed. <br /> EDAW Manteca WQCF and Collection System Master Plans EIR <br /> Terrestrial Biological Resources 4.5-2 City of Manteca <br />
