City of Santa Ana Updated Proposal for the 301 East Jeanette Lane tiau?•?r?=._ 1?? Residential Project Mitigated Negative Declaration 0. GREENHOUSE-GAS/GLOBAL CLIMATE CHANGE RBF's in-house global climate change experts are at the forefront in developing sound scientific assessments and strategies within the rapidly changing regulatory environment, As a result of our experience, RBF has developed proprietary models forquantifying and analyzing greenhouse gases from a variety of direct and Indirect sources including construction and vehicular traffic, The scope of work is as follows: Emissions inventory, RBF will prepare an inventory of the greenhouse emissions (GHG) from both direct and indirect sources. The emissions inventory will be quantlfed with the CalEEMod model. The analysis will determine the project's impact by determining if it is consistent with the Assembly Bill 32 mandate of reducing GHG's beyond "Business as Usual" conditions. The GHG reduction associated with the project's design features will be quantified utilizing the California Air Pollution Control Officers Association (CAPCOA) methodology (Quantifying Greenhouse Gas Mitigation Measures - A Resource forLocal Government to Assess Emission Reductions from Greenhouse Gas Mitigation Measures [September 2010]), indirect impacts. In response to Executive Order S-13-08 (2009 California Adaptation Strategy), RBF will identify and analyze the indirect impacts to the project from anticipated climate change. Such impacts include rising sea levels, public health threat caused by higher temperatures and more smog, damage to agriculture, habitat modification and destruction, higher risk of fires, and increased demand of electricity. Based on the GHG modeling and analysis described above, the Initial Study will include a detailed analysis of impacts in accordance with the CEQA Guidelines, The Initial Study will include an analysis of project-related GHG emissions, indirect impacts, and energy consumption. Mitigation measures to reduce impacts will be included in the Initial Study, if required. H. HAZARDS AND HAZARDOUS MATERIALS The review will address short-term and long-term hazardous material conditions that may be resulting from prior uses on- site. The analysis will be based upon references provided by the City and/or Project Applicant. If no hazardous conditions have been identified, this section will conclude no resulting impacts. HYDROLOGY AND WATER QUALITY Based upon available information from the City and project applicant, RBF will prepare the analysis addressing the hydrology and water quality impacts associated with the proposed residential development to address the following topical questions, which are similar to Appendix G (VIII) of the CEQA Guidelines: • Alterations of existing drainage patterns of the site orarea, in a mannerwhich would resultin substantial flooding erosion or siltation on- or off-site; • Create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff; • Place within a 100-year flood hazard area structures which would impede or redirect flood flows; and • Expose people or structures to a significant risk, including flooding as a result of the failure of a levee or dam. The section will address changes in absorption rates, drainage patterns, storm drain improvement, and downstream affects. RBF will also evaluate water quality conditions and identify water quality (NPDES) techniques/structures in accordance with local, State and Federal requirements, The potential for the project description to degrade water quality, interfere with groundwater recharge or expose people to water related hazards will be identified. This task specifically excludes any new modeling for hydrology or water quality. JN 132203 0 5 0 February 25, 2013 25C-16
