Less than Significant Impact. No Impact
Less than Significant Impact. A project is deemed inconsistent with air quality plans if it would result in population and/or employment growth that exceeds growth estimates included in the applicable air quality plan. The proposed project would not result in permanent population or employment growth, as it involves the short-term construction of wetlands and wildlife habitat and periodic monitoring thereafter. No significant long-term operational air quality emissions are anticipated to occur with implementation of the proposed project. The habitat lands will be maintained according to an approved management that details water management and, vegetation control that would ensure there would be no significant increase in emissions compared with the baseline (farming).
Less than Significant Impact. The proposed project would be constructed using diesel- powered heavy equipment. Diesel exhaust from construction activities may generate temporary odors while project construction is under way. However, there are no sensitive receptors of substantial numbers of people within the vicinity of the project. IV.
Less than Significant Impact. The Soil Survey of Yolo County, California (Soil Conservation Service 1972) indicates that the primary soil on the project site is Capay clay, flooded (Cc). This is a non-prime Class IV soil with an erosion hazard of “none to slight.” Grading disturbance caused by the project has a less than significant potential to increase erosion and sedimentation above preconstruction levels. As a standard condition of project approval, the applicant will be required to prepare and implement a Stormwater Pollution Prevention Plan (SWPPP). The SWPPP shall address erosion, stormwater runoff, sedimentation, and other construction-related pollutants during project construction and shall ensure all areas disturbed during construction are permanently stabilized. Implementation of a SWPPP would substantially minimize the potential for project-related erosion and associated adverse effects on water quality. In addition, all disturbed areas will be seeded and/or planted following construction to prevent soil erosion.
Less than Significant Impact. The project could affect GHG emissions through equipment used during grading activities and vehicle trips generated by employees, as well as physical changes in the vegetation of the land and the reduction in agricultural activities. However, as noted above in the Air Quality section, short-term air quality and GHG impacts will be generated by a relatively brief period (101 days for Phase I and 125 days for Phase II) of grading activity and a small number of employee commute trips (approximately six to twelve employees generating 12 to 32 trips per day over the construction period).
Less than Significant Impact. The project could be affected by climate change impacts, specifically sea level rise. The project is located in the Yolo Bypass area and portions of the project site are currently flooded on a regular basis. Projections of the sea level rise caused by global warming and climate change have been prepared by the USGS, and are included in the Final EIR of the 2030 Yolo Countywide General Plan (Yolo County, 2009b). The USGS projections show that areas within the one meter average daily tidal range will be inundated by sea level rise by 2100. These inundated areas include large portions of the southern portion of Yolo County including the project site.
Less than Significant Impact. The proposed project will require the short-term use of construction equipment for grading, and the storage of fuel and oil for the equipment. Construction equipment used on the site would include excavators, backhoes, scrapers, dump trucks, and water trucks. or the environment. The construction equipment associated with this project typically uses only a minor amount of hazardous materials, primarily motor vehicle fuels and oils. There is a danger that these materials may be released in accidental spills and result in harm to the environment. As a standard condition of approval, the construction contractor will be required to prepare and implement a Storm Water Pollution Prevention Plan (SWPPP), as described below, to ensure that the risk of accidental spills and releases into the environment would be minimal.
Less than Significant Impact. A Phase I Environmental Site Assessment was not been conducted for the project site. However, the site is undeveloped with any structures except for a recent barn and has been intensively cultivated in rice. There is no evidence of environmental impairment of the property from off site sources and no nearby contamination.
Less than Significant Impact. The proposed project will result in the creation of open water and xxxxx habitats that have the potential to result in increased mosquito populations. In order to minimize potential health hazards related to mosquito breeding, the project proponent will be required to coordinate the design and ongoing management of the project with the Sacramento- Yolo Mosquito & Vector Control District. A Condition of Approval for the project will require the applicant to comply with any feasible Best Management Plans proposed by the District. VIII.
Less than Significant Impact. The project requires the issuance of a flood permit by Yolo County. According to Section 8-3.401 of the Yolo County Code, a Flood Hazard Development Permit shall be obtained before any construction or other development begins within any area of special flood hazards. According to Section 8-3.403(a) of the County Code, the Floodplain Administrator shall review all Flood Hazard Development Permits to determine that:
