A description of the anticipated impacts that the covered activity will have on the occurrence and/or how the project will avoid impacts to all covered and no-take plant species. All projects must demonstrate avoidance of all six no-take plants (see table 6-5 of the HCP/NCCP).. Though habitats suitable for covered and no‐take plant species were identified during the planning survey conducted on July 5, 2012 at 8:00 AM (as indicated in Table 2b), none of the covered or no‐take plant species were observed. Covered and no‐take species typically found in alkali wetland and alkali grassland land cover types were included in the survey along with plant species typically found in annual grassland and seasonal wetland. This survey occurred during the blooming period of the following five species: brittlescale (Atriplex depressa), San ▇▇▇▇▇▇▇ spearscale (Atriplex joaquiniana), big tarplant (Blepharizonia plumosa), ▇▇▇▇▇▇’▇ dwarf flax (Hesperolinon breweri), and Mount Diablo buckwheat (Eriogonom truncatum). Based on Appendix D of the HCP/NCCP, suitable habitat is present at the project site to support brittlescale and occurrences of San ▇▇▇▇▇▇▇ spearscale are known in the Brushy Creek watershed. Low potential habitat is present to support big tarplant, and ▇▇▇▇▇▇’▇ dwarf flax has no potential to occur as the project is not within 500‐foot buffer from oak woodland or chaparral scrub. Mount Diablo buckwheat is not included in Appendix D. The plant survey portion of the planning survey was conducted in accordance with the California Native Plant Society survey guidelines. A plant list was made of all identified species within the planning survey area. Because of the dry conditions of the site and the desiccated state of much of the vegetation, species that could not be identified in the field were collected and identified later using the ▇▇▇▇▇▇ manual. Whenever possible, plants were identified to the species level. None of the five species were found during the July planning survey. Because the survey was conducted during the blooming period of these five species, it is appropriate to conclude that they are not present in the project footprint or the surrounding 325‐foot buffer, which was also included in the planning survey. A spring survey will be conducted in April 2013 to cover species with blooming periods that occur earlier in the year and thus could not be included in the July 2013 survey. These species include: caper‐fruited tropidocarpum (Tropidocarpum capparideum), Contra Costa goldfields (Lasthenia conjugens), recurved larkspur (Delphinium recurvatum), alkali milkvetch (Astragalus tener var. tener), diamond‐petaled poppy (Eschscholzia rhombipetala), large‐flowered fiddleneck (Amsinckia grandiflora), Mount Diablo fairy‐lantern (Calochortus pulchellus), round‐ leaved filaree (California macrophylla), showy ▇▇▇▇▇ (▇▇▇▇▇ radiata), and adobe navarretia (Navarretia nigelliformis ssp. nigelliformis). A rare plant survey report shall be submitted to the East Contra Costa County Conservancy after the spring survey is conducted. If special‐status plant species are identified on or within 325 feet of the repair areas and access areas, the applicant will be required to meet and confer with Conservancy staff to develop and implement a suitable plan to address Conservation Measure
