Consolidated Forward Inc. Landfill Page 24 74 Austin 2000 W14. b) (Greater western mastiff bat) Maternity sites should be avoided until bats finish rearing young. Prior to the bats finishing rearing their young, bat roosts/maternal "bat houses" should be placed within a protected area in the vicinity of the roosting/maternity sites if possible. As soon as young are flying and foraging, the maternity sites should be sealed. Similarly, once bat houses are installed in protected areas, bats should be evicted from their roost sites within the project construction zone (i.e., should be evicted from the trees to be removed). Removal of roost sites should occur during dusk or evening after bats have left the sites unless otherwise approved. These measures are consistent with the SJMSCP. 75 Austin 2000 (F14.0 (Greater western mastiff bat) Pre -construction surveys would prevent direct take of individuals or maternity sites. No immediate replacement of roosting habitat has been proposed. If a maternity roost or occupied roost is detected during pre -construction surveys, the SJMSCP JPA shall provide adequate replacement for loss of occupied habitat should be designed and implemented with input from CDFG. Implementation of these mitigation measures would reduce impacts to levels considered less than significant. 76 Austin 2000 (F15.a) The project sponsors or the SJMSCP JPA should fund and conduct pre -construction protocol surveys for burrowing owls in all ruderal and non-native grassland habitats within the project site. Surveys should be conducted as recommended in the Staff Report on Burrowing Owl Mitigation (CDFG 1995) and as otherwise prescribed in the Burrowing Owl Survey Protocol and Mitigation Guidelines (BOC 1993). If burrowing owl are observed during surveys, the extent of burrowing owl habitat on the project site would be delineated by a qualified ornithologist. Avoidance and mitigation would be pursuant to new guidelines provided by CDFG and/or as specified by the SJMSCP. 77 Austin 2000 (F15.0 (Burrowing owls) If the project sponsor elects to mitigate in accordance with the SJMSCP, then the JPA may fund and conduct pre -construction surveys to prevent direct take of individuals or nests. Pre -construction surveys should be conducted within 30 days prior to ground disturbance. These actions would reduce any significant adverse impacts to burrowing owl to a level considered less than significant. This mitigation option would also reduce impacts to this species habitat to a level considered less than significant by including pre -construction surveys in combination with payment of SJMSCP fees. In addition, methods to prevent occupation of the site by burrowing owls during construction should be employed, consistent with the guidelines in the SJMSCP. These methods include installation of one-way doors in occupied burrows, maintaining vegetation cover that discourages burrowing ground squirrels, disking to destroy burrows, or control of ground squirrel populations. L PUBLIC SERVICES AND UTILITIES 78(1.1) Proposed as Part of the Project: The landfill supervisor will be responsible for providing overall site security during normal working hours.
