Adverse effect on candidate, sensitive, or special-status plant and wildlife species DSP, DSP-V, CPP, & CPP-V scenarios |
4.C-1b: Documented plant occurrences on Icehouse Hill shall be avoided by establishing a buffer zone of no less than 25 feet prior to Project trail construction, or other ground-disturbing activities having the potential to disturb or result in mortality of special-status plant populations. This buffer zone, whose specific width shall be determined based on site-specific analysis of proposed construction techniques and their potential for dust creation, shall be demarcated using flagging, orange fencing, or any other visual barrier between plant populations and the active disturbance footprint. Buffer distances may be increased if hydrology features would be altered as a result of train |

If the surveys required in Mitigation Measure 4.C-1a identify special-status plants on Icehouse Hill, the Community Development Director shall ensure that the final survey report incorporates the additional requirements of Mitigation Measure 4.C-1b in the final survey report required by Mitigation Measure 4.C-1a. |

Trail configurations shall be sited to avoid special- |

status plants and Viola pedunculata. In the event the |

City determines that trail construction cannot be |

accomplished without disturbance or mortality then trail |

construction would be abandoned and Icehouse Hill |

would remain closed for public uses. |

To reduce impacts from off-trail use, and increased |

horse use in association with trail riding, trail head |

signage shall be required to educate the public |

regarding sensitive resources and restoration that |

would be affected by off-trail use. Protected areas shall |

be marked in perpetuity. Trail use rules shall be |

developed prior to trail construction, and in addition to |

limiting use to identified trails, may include other |

requirements to limit the possibility that sensitive |

species would be impacted. |

plant species for special status butterflies shall be |
