Red Morton Park Regional Stormwater Capture Project Redwood City, CA not include, or the proposed project activities would not have the potential to substantially affect and/or exacerbate, the following resources: Aesthetics/Visual Resources, Agricultural and Forestry Resources, Energy, Geology and Soils, Hazards and Hazardous Materials, Land Use/Planning, Mineral Resources, Population and Housing, Public Services, Utilities and Service Systems, and Wildfire. In addition, the project is anticipated to have a beneficial to hydrology and water quality resources from improved downstream water quality and ground water recharge. The following issues and CEQA-required considerations are expected to be discussed in greatest detail in the Administrative Draft IS: Air Quality and Greenhouse Gases (GHG): The air quality and GHG impacts of the proposed project would be primarily generated during the construction of the project. The Consultant will prepare a clear and concise air quality/GHG impact assessment that evaluates and quantifies the project's potential impacts in accordance with the Bay Area Air Quality Management District's (BAAQMD) CEQA Air Quality Guidelines, the City's General Plan, and the City's Climate Action Plan. The analysis will focus on the amount of emissions of criteria air pollutants (e.g., particulate matter, or PM, and oxides of nitrogen, or NOx) and toxic air contaminants (TAC) that would be generated by project construction and operation. The Consultant will use the California Emissions Estimator Model (CalEEMod) to quantify project emissions and compare project emissions levels against the latest CEQA significance thresholds recommended for use by the BAAQMD. The team anticipates the project would need to incorporate best management practices and/or mitigation measures to reduce project construction emissions, particularly fugitive dust emissions, to less than significant levels. The proposed project is likely to require a large amount of soil excavation and export, on-site heavy duty diesel equipment use, on-site diesel truck idling, and off-site diesel truck trips in close proximity to sensitive residential and other receptors. The Consultant, therefore, will conduct a construction health risk assessment (HRA) for the project. The team will use the U.S. EPA -approved and BAAQMD- recommended regulatory model (AERMOD) to predict exposure to concentrations of diesel PM, a TAC, at sensitive receptor locations and quantify associated health risks. The constructional HRA will be prepared in accordance with the guidance and recommendations provided by the BAAQMD and the California Office of Environmental Health Hazard Assessment's (OEHHA) Air Toxics Hot Spots Program Guidance Manual. The Consultant anticipates the use of late model construction equipment meeting U.S. EPA Tier III or IV emissions standards will be necessary to demonstrate project construction activities would not result in significant adverse health risks to student or residential receptors. Biological Resources and Jurisdictional Waters: The IS will present a comprehensive biological resource setting discussion, a summary of applicable regulations and permits required, and mitigation measures included in the project to avoid any impacts to biological resources. Should the resource agencies require a biological resources report and/or jurisdictional waters delineation, the biology section will present this information. Cultural /Tribal Cultural Resources: The Consultant Archaeologist will evaluate potential impacts to cultural and tribal cultural resources consistent with CEQA Guidelines Section 15064.5. The project is anticipated to involve excavation at depths of 10 feet or more below ground surface near Arroyo Ojo, and creeks are generally known to be areas with a high potential to contain recorded and/or unrecorded cultural and tribal resources that may be encountered or discovered during development activities. The Consultant, therefore, will request a search of the California Historical Resource Information System (CHRIS) and the Native American Heritage Commission (NAHC) Sacred Lands File (SLF) to determine if there are known cultural/tribal cultural resources in or near Red Morton Park. In addition, as required by CEQA, local tribes will be contacted as directed by the NAHC as an extension of the SLF search to identify potential tribal cultural resources that may not be known by the NAHC due to their specific importance to an individual tribe. Due to the anticipated depth of excavation, The Consultant will also conduct a paleontological search with the Museum of Paleontology at UC Berkeley. MIG, a subconsultant, anticipates that standard measures for the protection of recorded (i.e., known) and unrecorded (i.e., unknown) resources, such as stop work provisions, will be incorporated into the project as Best Management Practices or mitigation measures to render impacts on cultural/tribal cultural resources a less than significant impact.
