In determining potential air quality impacts, Urban Crossroads utilizes industry-standard models to study the source-specific pollutant emissions. Urban Crossroads staff has extensive experience using United States Environmental Protection Agency (US EPA) Air Dispersion models, including ISCST3 and AERMOD; and air quality Models accepted for use in California including CalEEMod, URBEMIS, EMFAC, CALINE4 and CAL3QHC.
Urban Crossroads Inc. has been advising clients on greenhouse gas and climate change since the passage of the Global Warming Solutions Act of 2006 (AB 32). Our staff has been at the forefront working both collaboratively and tirelessly with local agencies and project proponents on how best to address greenhouse gases in CEQA documents due to the evolving nature and lack of technical guidance. Our staff is also actively involved in the development of Climate Action Plans (CAPs) for local jurisdictions.
Whether a Project is adjacent to an existing freeway or a Project results in heavy-duty diesel trucks with the potential to emit air toxic and criteria pollutants, Urban Crossroads, Inc. staff has extensive experience with the analysis and mitigation of air toxic and criteria pollutants. Urban Crossroads Inc. has a strong technical background in the preparation of air toxic and criteria pollutant health risk assessments. Urban Crossroads Inc. prepares air toxic and criteria pollutant health risk assessments for both on-site and off-site sensitive land uses.
A health risk assessment is typically prepared when either a Project is emitting toxic and criteria pollutants to the surrounding community or when a Project is subjected to toxic and criteria pollutants based on the existing environmental setting. Our staff utilizes industry-standard modeling methodology in order to accurately determine if potential health impacts may occur.
The purpose of an Energy Analysis Report is to satisfy Appendix F (Energy Conservation) of the 2014 CEQA Statute and Guidelines and ensure that the energy implications of a proposed Project are considered through the quantification of anticipated energy usage associated with the construction and operation of a proposed Project, as well as a determination of whether the Project results in an efficient, typical, or wasteful use of energy. Appropriate mitigation measures, if necessary, are also identified for inclusion in the CEQA document.
Appendix F requires an analysis of a Project’s potential energy use including transportation-related energy, sources of energy supply, and ways to reduce energy demand, including the use of efficient transportation alternatives. CEQA Guidelines provide specific recommendations regarding factors to consider when analyzing a Project’s energy impacts, such as transportation energy use, the effect of the project on local and regional energy supplies, and the types of energy that may be consumed during construction and operation of the proposed Project.
