The proposed tie in location is within a fenced utility enclosure adjacent to a paved maintenance yard. The tie-in location is graded, graveled and lacks groundcover vegetation. Photo 3: Tie-in Location The Pleasanton Canal (a flood control channel) is located to the south of the tie-in location; the channel is separated from the tie-in location by a fence. The Pleasanton Canal flows into the Arroyo de la Laguna, which eventually joins San Ramon Creek. The channel is confined to a constructed trapezoidal flood control channel. At the time of the site visit (which followed a period of heavy rain) there were pockets of standing water, but much of the channel was dry and/or choked with vegetation such as tules (Schoenoplectus sp.) and curly dock (Rumex crispus). Both channel banks are dominated by a dense growth of ruderal plant species and non- native grasses, including species such as wild oats (Avena sp.) and poison hemlock (Conium maculatum). There is no riparian vegetation along the channel, and the channel is outside of the project's disturbance area. 5
