` Draft Supplemental Environmental Impact Report Page IVY-32 <br /> Forward Inc.Landfill 2014 Expansion Project <br /> HCP mitigation fees associated with the loss of foraging habitat for this area. <br /> Most of the southeast landfill relocation area currently is used as a composting facility and <br /> provides little wildlife habitat value. In this area, the ground is covered with rows/piles of <br /> r. composed and there is no vegetation. This area would be replaced with a capped landfill, <br /> which in the long-term would likely provide improved wildlife habitat value. The proposed <br /> sedimentation and lechate ponds would be constructed in the vicinity of an existing lechate <br /> ` pond and/or within disturbed habitats;therefore these project components would not <br /> substantially alter the current habitat value. Also, the landfill implements a rodent control <br /> program, which further detracts from the habitat quality of the site by limiting prey for raptors. <br /> The proposed relocation of the South Branch of the South Fork of Little John's Creek would <br /> result in a net increase in riparian and wetland vegetation. No trees are located on the project <br /> site, and therefore none would be removed as part of the project. <br /> Swainson's hawk(a state-listed species) and other special-status bird species forage over <br /> grassland habitat and may use the existing landfill habitats for foraging. However, the value of <br /> the property for foraging raptors is limited by the ongoing rodent control program. <br /> ` Additionally, the habitats to be disturbed by the project(i.e., disked areas devoid of vegetation <br /> and an active compost facility) provide limited value for foraging raptors. These areas would <br /> be replaced with a capped landfill providing similar or improved wildlife habitat value in the <br /> long-term. In the short-term, there would be a loss of habitat potentially used by Swainson's <br /> hawks as foraging habitat and the County considers any loss of potential Swainson's hawk <br /> habitat to contribute to a significant county-wide impact. While the property owner has already <br /> paid the HCP mitigation fees associated with the loss of foraging habitat for the proposed <br /> ` northeast landfill development area, the HCP mitigation fees have not been paid for the 6.2 <br /> acres to be developed in the southern portion of the property. Therefore, the loss of wildlife <br /> habitat(including raptor foraging habitat) is considered a cumulatively significant impact. <br /> ` Mitigation Measure F.B. The project shall comply with the SJMSCP mitigation requirements <br /> for the conversion of row and field crop lands (SJCOG 2000). Under the SJMSCP (2000),each <br /> acre of Swainson's hawk habitat(i.e.,Agricultural Habitat Lands) converted to non-open space <br /> uses would be mitigated by the establishment of 1 acre of Row and Field Crop/Riparian <br /> Preserve (a 1:1 mitigation ratio). This measure would apply to the 6.2 acres of land to be <br /> developed in the southern portion of the property. <br /> This would reduce this impact to a less than significant level. <br /> Impact F.9. Increase in Existing levels of Night Lighting. Night lighting is not expected to <br /> ` increase, as all project components would be within the boundaries of the existing active landfill <br /> facility area.This is a less than significant impact and no mitigation is required. <br /> •• Impact F.10. Use of Rodenticides in the Capped Areas of Landfill Could Result in Adverse <br /> Impacts to Wildlife. As part of permits issued to landfills, rodent control is important to <br /> maintaining the integrity of the landfill cap and liner to prevent leaching or seepage. Rodent <br /> " control is conducted through the application of rodenticides that is regulated through the <br /> Department of Agriculture. Application of rodenticides could adversely affect predator species, <br /> such as raptors and carnivores that feed on rodents on the site. When poisoned rodents are <br /> depredated, they can deliver significant doses to the predator. Raptors that eat small mammals <br /> in urban and agricultural areas are at risk of secondary poisoning from anticoagulant <br /> rodenticides,which can cause internal hemorrhaging and mortality. Some anticoagulants take <br /> several days to work(e.g.,brodifacoum) even with lethal doses, allowing rodents to forage and <br /> .. be exposed to raptor predation before dying. As a participant in the SJMSCP, Forward <br /> proposes to incorporate SJMSCP guidelines developed to minimize potential effects of <br />
