1 MITIGATION MONITORING AND REPORTING PROGRAM The California Public Resources Code, Section , requires that a lead or responsible agency adopt a mitigation monitoring and reporting plan when approving or carrying out a project when an MND identifies measures to reduce potential environmental impacts. As lead agency for the project, the County is responsible for adoption and implementation of the mitigation monitoring and reporting program. Biological Resources BIO-1 Prior to removal of any vegetation that shall occur between September 1 X X County of Orange in and January 1. If this timing is not feasible and removal must occur between consultation with January 1 and August 31, a nesting bird survey shall be conducted by a qualified California biologist no more than 72 hours prior to planned vegetation removal activity. If Department of Fish occupied nests are present, vegetation shall not be removed until the young have and Wildlife fledged and the nesting cycle is deemed complete by a qualified biologist. BIO-2 Prior to the start of construction, but no longer than 72 hours in advance of X X County of Orange in construction, a nesting bird survey will be conducted by a qualified biologist and consultation with approved by the California Department of Fish & Wildlife. If nests are discovered California during the pre-construction survey, the biologist will identify an appropriate setback Department of Fish zone the construction crew must observe in order to ensure that existing noise and Wildlife levels remain. Once the juvenile birds have fledged or the nest is deemed no longer active by a qualified biologist, construction restrictions/monitoring shall cease.

2 must be indicated on project plans. These plans shall be reviewed by the Civic Center Authority. The County will evaluate comments received from the Civic Center Authority and implement them accordingly. Additionally, removal of any palm trees located in the Plaza of the Flags will be conducted under the supervision of a certified arborist. The contractor responsible for removal of any palm trees in the Plaza of the Flags will replace the palm trees in accordance with any established Civic Center guidelines, if any after construction and ensure the trees survival after removal and before replacement. Cultural Resources CUL-1 Prior to grading/excavation activities, the County of Orange (County) shall prepare an archaeological monitoring plan that includes an on-site, Countyapproved archaeological monitor to oversee initial grading/excavation and any subsurface work anticipated during pipeline trenching activities. In the event that archaeological resources are encountered, the archaeological monitor shall have the authority to stop all construction work in the vicinity of the discovery until a qualified archaeologist can evaluate the discovery. activities may continue in other areas, but should be distanced at least 100 feet from the find. If the discovery proves significant under CEQA (Section f; PRC 21082), additional work such as testing or data recovery may be warranted. CUL-2 Prior to grading activities, the County shall prepare a paleontological monitoring plan that includes an on-site, County-approved paleontological monitor to oversee initial grading and any subsurface work anticipated during pipeline trenching activities. In the event potential paleontological resources are encountered, the monitor shall have the authority to stop all construction work in the consultation with the Civic Center Authority X X X X County of Orange in consultation with California Office of Historic Preservation X X X X County of Orange in consultation with California Office of Historic Preservation Date of 2 December 2015 Page 2 of 11

3 vicinity of the discovery until a County-qualified paleontologist can evaluate the discovery to determine whether it is scientifically significant. If the resource is determined to be of significance, specific steps shall be implemented, as indicated in the plan and under the direction of the paleontologist, to protect the resource. Such steps would possibly include salvage. CUL-3 In the event that any sites containing human remains are inadvertently discovered during excavation or pipeline drilling/trenching, construction will cease in the vicinity of the discovery or any nearby area and the following actions will be taken: The County Coroner s Office shall be notified immediately. If the County Coroner determines that the remains are Native American, the Native American Heritage Commission shall be contacted within 24 hours, per California state law (California Public Resources Code, Section ). The Native American Heritage Commission shall designate a most likely descendant, who may make recommendations concerning the disposition of the remains and associated grave goods in consultation with the County. If the Native American Heritage Commission is unable to identify a most likely descendant or if the most likely descendant fails to make a recommendation within 24 hours, or if the County rejects the recommendations of the descendant and mediation efforts fail to provide measures acceptable to the County, then the County or its designee shall rebury the remains and associated grave goods in an area that shall not be disturbed. Only after the above actions are taken and the inadvertent discovery of human remains is resolved will construction activity begin again.
