The restoration area monitored as part of this monitoring report differs from the refereced area included in the amended Biological Opinion (letter from YinLan Zhang, SFPUC, to Angela Picco, USFWS, dated January 27, 2010). The Biological Opinion indicates that three parking and staging areas would be utilized. However, project related construction activities within the vegetated areas were limited to one southern parking and staging area (see Figure 1) which was the only subsequent area to be revegetated. This restoration area, approximately 0.4 acres in size, is located at 66 Cañada Road, Redwood City on the southwest side of the Pulgas Dechloramination Building just outside the security fence.

Construction was completed on June 6, 2011. Starting on October 20, 2011, Yerba Buena Engineering removed any remaining debris, prepared the seed bed, hydroseed, and installed permanent stormwater pollution prevention devices. The seed mix is detailed in Table 1 below.

Year 1 revegetation monitoring was conducted by Plant Ecologist, Barbara Malloch Reitner on September 27, 2012. Year 2 annual revegetation monitoring was conducted by the Alameda County Resource Conservation District (ACRCD) with the assistance of the Natural Resources Conservation Service and Ecosystems West Consulting Group on April 30, 2013. Additional site visits were conducted by the ACRCD on March 7, May 29 and August 2, 2013 to assess weeding needs.

Overall, vegetation cover was moderate in the revegetation site. Several of the native seeded species were observed: California brome (Bromus carinatus), purple needlegrass (Stipa pulchra [=Nassella pulchra]), blue wildrye (Elymus glaucus) and yarrow (Achillea millefolium). Other native species observed included centaury (Centaurium sp.) and hayfield tarplant (Hemizonia congesta), which was present in abundance at the site and surrounding area during the August visit. The revegetation area was dominated by three naturalized non-native annual grasses: Italian rye-grass (Festuca perennis [=Lolium multiflorum]), wild oats (Avena sp.), and soft chess (Bromus hordeaceus). These species are assumed present prior to project implementation and likely have persisted as seeds in the soil. The surrounding grasslands at the project area include the presence of these naturalized non-native annual grasses as well. Non-native invasive species observed in the revegetation site included yellow star thistle (Centaurea solstitialis), purple velvet grass (Holcus lanatus, observed at the northwestern edge of the site), Italian thistle (Carduus pycnocephalus), bull thistle (Cirsium vulgare), and stinkwort (Dittrichia graveolens). These invasive weeds have been treated by the SFPUC following the monitoring and weed assessment visits.

The overall plant cover was moderate in the revegetation site; vegetation cover is slightly lower along the road due to the compacted soil next to the road. Invasive weeds had a moderate presence at the site, but have been treated during regular site maintenance. Although there was limited representation of the seeded species, typical grassland species have started to establish at the site without reseeding. Continued weed control is recommended to allow native and naturalized grassland species to become established.
