5.0 Environmental Analysis 5.2 Biological Resources <br />Avion Project SEIR <br />Page 5.2-1 <br />5.2 Biological Resources <br />This section evaluates potential biological resources impacts associated with the project. The <br />following discussion is based on the Biological Technical Report and appendices (including the <br />Jurisdictional Waters Delineation) (RECON 2019a) prepared by RECON and included as Appendix B. <br />5.2.1 Relationship to the Black Mountain Ranch <br />(Subarea I) Subarea Plan <br />The analysis in this section updates the biological resources analysis in the 1998 Environmental <br />Impact Report (EIR), with an emphasis on effects that were not addressed in the previous report. <br />5.2.2 Existing Conditions <br />RECON biologists conducted a general biological survey of the project site on November 13 and <br />December 8, 2017, to document the existing conditions of the biological resources occurring on the <br />site. The project site was walked on foot and notes were taken on the flora and fauna observed <br />during the survey (Table 5.2-1). A jurisdictional waters delineation was conducted on November 29, <br />2017 on the site to locate the extent of any wetland and non-wetland waters. A spring survey for <br />sensitive plant species was conducted on the site on March 21, 2018. This survey also included a <br />focused spring survey for thread-leaved brodiaea. Additional focused surveys for thread-leaved <br />brodiaea were conducted on March 14 and April 12, 2019. <br />Table 5.2-1 <br />Survey Dates, Times, and Weather Conditions <br />Date Surveyors Type of Survey Beginning Conditions <br />Ending <br />Conditions <br />11/13/17 Gerry Scheid <br />Beth Procsal General Biology Survey <br />8:00 a.m.; 60° F; wind <br />0-1 mph; <br />60% cloud cover <br />12:00 p.m.; 72° F; <br />wind 0-1 mph; 40% <br />cloud cover <br />11/29/17 Gerry Scheid Wetland Delineation <br />12:00 p.m.; 75° F; wind <br />0-1 mph; <br />30% cloud cover <br />5:00 p.m.; 65° F; wind <br />0-1 mph; 30% cloud <br />cover <br />12/8/17 Gerry Scheid <br />Beth Procsal General Biology Survey <br />8:00 a.m.; 65° F; wind <br />0-1 mph; <br />50% cloud cover <br />12:00 p.m.; 74° F; <br />wind 0-1 mph; 20% <br />cloud cover <br />3/21/18 Gerry Scheid <br />Spring Rare Plant Survey; <br />Focused Thread-leaved Brodiaea <br />Survey <br />10:00 a.m.; 70° F; wind <br />0-5 mph; <br />20% cloud cover <br />2:00 p.m.; 75° F; wind <br />0-5 mph; 20% cloud <br />cover <br />3/14/19 Gerry Scheid <br />Spring Rare Plant Survey; <br />Focused Thread-leaved Brodiaea <br />Survey <br />NA NA <br />4/12/19 Gerry Scheid <br />Spring Rare Plant Survey; <br />Focused Thread-leaved Brodiaea <br />Survey <br />NA NA <br />NA = not applicable. <br />° F = degrees Fahrenheit; mph = miles per hour
