Pre-construction surveys to determine if western burrowing owl, are present within the area of disturbance of the road widening should be conducted by a qualified biologist no more than 30 days prior to the initiation of any construction related activities. Dublin Public Works Department Dublin Public Works Department Construction Plans and Specifications Dublin Public Works Department Dublin Public Works Department Prior to construction Page 3 City of Dublin, Ultimate Right-of-Way Lines for Tassajara Road and Fallon Road Mitigation Measure Implementing Responsibility Monitoring Responsibility Monitoring Schedule Verification If burrowing owls are observed on or near the project site during these surveys, the project will implement an exclusion zone around the nest location. Exclusion zones should be 160 feet during the non-breeding season of September 1-January 31. Passive relocation of owls that includes the placement of one-way doors over burrow entrances, allowing owls to exit but not return, may be used at that time. During the breeding season of February 1-August 31, exclusion zones should be at least 250 feet from occupied burrows. Ail project related activity will occur outside of the exclusion area until the young have fledged (California Department of Fish and Game, 1995). If owls are detected breeding within the construction zone, 6.5 acres of burrowing owl habitat shall be preserved for each active nest detected. The location of the preserved habitat shall be determined in consultation with the CDFG. To the fullest extent possible, mitigation areas shall be located on the adjoining property where owl habitat is identified. Page 4 City of Dublin, Ultimate Right-of-Way Lines for Tassajara Road and Fallon Road Mitigation Measure Implementing Responsibility Monitoring Responsibility Monitoring Schedule Verification Mitigation Measure 9 (Biological Resources). Surveys to determine if California tiger salamander are present within the area of disturbance of the road widening should be conducted by a qualified biologist. These surveys should be conducted in accordance with the protocols outlined by the CDFG. If California tiger salamanders are determined to be present, the project will implement a salvage program. The salvage program will include placement of fencing to prevent movement of salamanders into the project site and trapping in the project area to capture salamanders for relocation to off-site locations. The project shall preserve California tiger salamander habitat at a 1:1 (mitigation area: impact area) replacement ratio. All preserved acreage must be protected in perpetuity by designation as permanent open space with a conservation easement placed over it. The location of the preserved habitat will require the approval of the CDFG. CDFG approved mitigation habitat must be secured prior to construction of the bridge. To the fullest extent possible, mitigation areas shall be located on the adjoining property where tiger salamander habitat is identified.

Preconstruction surveys for the presence of San Joaquin kit fox shall be completed as required by the Eastern Dublin Specific Plan EIR. If San Joaquin kit fox are observed on or near the project site during these surveys, consultation with the U.S. Fish and Wildlife Service will be initiated and the project will incorporate the Terms and Conditions contained in the Biological Opinion. Mitigation Measures 3.7/18.0 through 19.0 as set forth in the Eastern Dublin EIR shall also be implemented. Dublin Public Works Department Dublin Public Works Department Prior to construction Page 6 City of Dublin, Ultimate Right-of-Way Lines for Tassajara Road and Fallon Road Mitigation Measure Implementing Responsibility Monitoring Responsibility Monitoring Schedule Verification Mitigation Measure 11 (Biological Resources). Measures shall be implemented to ensure California red-legged frogs and western pond turtle are not present within the disturbance area during development. Any project related work in or along the tributaries shall be restricted to the period when these features are dry (usually from mid-summer through October). A USFWS and CDFG approved biologist shall conduct pre-construction surveys to determine if California red-legged frog or western pond turtle are present within this area within three days prior to any construction activities. If any red-legged frogs are found, the biologist shall contact the USFWS to determine if moving them is appropriate. Immediately following the preconstruction survey, all portions of the project site proposed for grading shall be separated from open space areas by fencing appropriate to prevent California red-legged frogs and western pond turtle from entering the development area. Dublin Public Works Department Dublin Public Works Department Prior and during construction Page 7 City of Dublin, Ultimate Right-of-Way Lines for Tassajara Road and Fallon Road Mitigation Measure Implementing Responsibility Monitoring Responsibility Monitoring Schedule Verification A second survey shall be conducted within the fenced area no earlier than 24 hours before the onset of activities to ensure no California red-legged flogs or pond turtles are entrapped in the construction area by the fence. Any western pond turtles found within this area will be captured and relocated downstream. If relocation of red- legged frogs is allowed by the USFWS, any California red-legged frogs captured will be relocated downstream.

All trees within the construction zone which will need to be removed for road widening should be cut during the non- nesting season (August 1 to January 30) in the year prior to when road widening is expected to occur. If tree removal cannot occur as outlined above and must take place when road widening occurs then pre- construction surveys for active nests will be required. Surveys to determine the presence of raptor nests should be conducted by a qualified biologist no more than 30 days prior to the initiation of any construction related activities. If raptors are observed nesting on or near the project site during these surveys, exclusion zones will be established around all active nests. The project will consult with CDFG to determine the size of the exclusion zone, usually 100-300 feet, around the nest location. All project related activity will occur outside of the exclusion area until the young in the nest have fledged. Dublin Public Works Department Dublin Public Works Department As noted in Mitigation Measure Page 9 City of Dublin, Ultimate Right-of-Way Lines for Tassaj ara Road and Fallon Road Mitigation Measure Implementing Responsibility Monitoring Responsibility Monitoring Schedule Verification Mitigation Measure 13 (Biological Resources). Surveys of the existing southern tributary culvert should be conducted by a qualified biologist to determine the presence of roosting bats no more than 30 days prior to the initiation of any construction related activities. If a bat roost is observed in the culvert during these surveys, the biologist will determine the type of roost, (daytime, nighttime, or maternity), and construction on and in the immediate vicinity of the culvert will stop until the bats have been excluded from the roost site. If a nighttime roost is present, any demolition work on the culvert will be limited to daytime hours when bats are not present. If a daytime roost is present, the roost site will be outfitted with bat exclusion devices that allow bats to exit the roost site, but not return. Demolition of the culvert will begin only after the biologist has determined that the roost has been successfully abandoned. If a maternity roost is present, the exclusion zone will remain in place until the young have fledged. After fledging, bats will be excluded and the culvert demolished as specified for a daytime roost. Both new bridges should be designed to permit bats to establish roost, after construction.

Exclusion fencing (construction or silt fencing) will be installed at the boundary between these features and the active project area to protect them and to delimit the boundary of construction and heavy equipment activity. A biological monitor shall oversee the installation of the fencing and periodically monitor the development sites to document avoidance of the off-site areas. The monitor will provide a report to the City and other agencies documenting the avoidance during construction.
