AUGUSTIN BERNAL MOUNTAIN BIKE TRAIL PROJECT DRAFT INITIAL STUDY compensatory mitigation for unavoidable permanent impacts on special-status plant occurrences shall be required based on recommendations of a qualified botanist. Given the amount of available habitat in Augustin Bernal Community Park, it is expected that compensatory mitigation could be accomplished at the park. Compensatory mitigation shall include the following components,at a minimum: • The botanist shall prepare a special-status plant mitigation plan that includes seed/propagule collection methods, success criteria 5 years of maintenance and monitoring, and adaptive management approaches. The special-status plant mitigation plan shall be implemented to document the success of creation of the new plant occurrence.Adequate funding for compensatory mitigation shall be provided on an agreed-to schedule. • Prior to unavoidable and permanent disturbance to any special-status plants, propagules shall be collected from the occurrence to be disturbed. This may include seed collection, cuttings, or seed-bearing topsoil salvage, and these propagules shall be used to establish a new population on suitable,unoccupied habitat.Transplantation of whole plants may be attempted, but shall not be used as the primary means for creating a new occurrence. 3.5 Cultural Resources Less Than Significant Potentially Impact With Less Than Significant Mitigation Significant Impact Incorporated Impact No Impact V. CULTURAL RESOURCES -Would the project: a) Cause a substantial adverse change in the significance of a historical resource ❑ ❑ ❑ ❑ pursuant to§15064.5? b) Cause a substantial adverse change in the significance of an archaeological ❑ ® ❑ ❑ resource pursuantto§15064.5? c) Disturb any human remains, including those interred outside of dedicated ❑ ® ❑ ❑ cemeteries? Setting Dudek staff completed a Cultural Resources Report (Appendix C) that evaluates the project's potential impacts on cultural resources. A records search was completed for the current area of potential effects (APE) and a 0.5-mile buffer by staff at the Northwest Information Center on March 25, 2021. The records search did not identify any cultural resources within the APE but based on previous studies within the records search area there is one identified cultural resource,the main clubhouse of the Castlewood Country Club, located approximately 0.45 miles east of the APE. Dudek consulted historic maps and aerial photographs to understand development of the APE (NETR 2021). Historic aerial photographs available 12956 DUDEK 46 April 2022
