HomeMy WebLinkAboutAir Quality and Green Gas Evaluation DATE: February 28, 2023 TO: Tracy Zinn, T&B Planning, Inc. FROM: Haseeb Qureshi, Urban Crossroads, Inc. JOB NO: 15283-02 AQ & GHG ALDER AND MERRILL AIR QUALITY AND GREENHOUSE GAS EVALUATION Urban Crossroads, Inc. is pleased to provide the following Air Quality and Greenhouse Gas Evaluation for the Alder and Merrill (Project), which is located north of Merrill Avenue, between Alder Avenue and Laurel Avenue in the City of Fontana. PROJECT OVERVIEW The Project consists of a proposed General Plan Amendment (GPA) and a Zone Change (ZC) for a 6.4-acre property that is located in the City of Fontana north of Merrill Avenue, between Alder Avenue and Laurel Avenue, and south of Citron Avenue. The GPA would change the General Plan land use designation of the Project site from Single Family Residential (R-SF) to Multifamily Medium High-Density Residential (R-MFMH) and the zoning of the Project site from Single Family Residential (R-1) to Multifamily Medium/High Density Residential (R-4). The existing General Plan land use and zoning are shown on Exhibit 1 and the proposed GPA and ZC are shown on Exhibit 2. The increased unit count allowance would increase from a maximum of 32 residential units (6.4 acres x 5.0 units/acre = 32 units) to 249 residential units (6.4 acres x 39 units/acre = 249 units), for a net increase of 217 units assuming maximum development potential under the existing and proposed designations. No development project is currently proposed, and no physical disturbance of the Project site is currently proposed. Only the proposed change to the underlying land use has been evaluated as part of this assessment. Tracy Zinn, T&B Planning, Inc.

The purpose of this model is to calculate construction-source and operational- source criteria pollutant (VOCs, NOX, SOX, CO, PM10, and PM2.5) and GHG emissions from direct and indirect sources; and quantify applicable air quality and GHG reductions achieved from mitigation measures (1). Accordingly, the latest version of CalEEMod has been used for this Project to determine construction and operational air quality and greenhouse gas emissions. Tracy Zinn, T&B Planning, Inc.

Climate Risk Summary Cal-Adapt midcentury 2040–2059 average projections for four hazards are reported below for your project location. These are under Representation Concentration Pathway (RCP) 8.5 which assumes GHG emissions will continue to rise strongly through 2050 and then plateau around 2100. Climate Hazard Result for Project Location Unit Temperature and Extreme Heat 26.4 annual days of extreme heat Extreme Precipitation 4.90 annual days with precipitation above 20 mm Sea Level Rise 0.00 meters of inundation depth Wildfire 0.00 annual hectares burned Temperature and Extreme Heat data are for grid cell in which your project are located. The projection is based on the 98th historical percentile of daily maximum/minimum temperatures from observed historical data (32 climate model ensemble from Cal-Adapt, 2040–2059 average under RCP 8.5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi. Extreme Precipitation data are for the grid cell in which your project are located. The threshold of 20 mm is equivalent to about ¾ an inch of rain, which would be light to moderate rainfall if received over a full day or heavy rain if received over a period of 2 to 4 hours. Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi. Sea Level Rise data are for the grid cell in which your project are located. The projections are from Radke et al. (2017), as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider different increments of sea level rise coupled with extreme storm events. Users may select from four model simulations to view the range in potential inundation depth for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 50 meters (m) by 50 m, or about 164 feet (ft) by 164 ft. Wildfire data are for the grid cell in which your project are located. The projections are from UC Davis, as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider historical data of climate, vegetation, population density, and large (> 400 ha) fire history. Users may select from four model simulations to view the range in potential wildfire probabilities for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi. 6.2.

Exposure is rated on a scale of 1 to 5, with a score of 5 representing the greatest exposure. The adaptive capacity of a project refers to its ability to manage and reduce vulnerabilities from projected climate hazards. Adaptive capacity is rated on a scale of 1 to 5, with a score of 5 representing the greatest ability to adapt. The overall vulnerability scores are calculated based on the potential impacts and adaptive capacity assessments for each hazard. Scores do not include implementation of climate risk reduction measures. 6.3.

Climate Risk Detailed Report 15283 - Alder & Merrill (Proposed) Detailed Report, 2/28/2023 23 / 29 6.1. Climate Risk Summary Cal-Adapt midcentury 2040–2059 average projections for four hazards are reported below for your project location. These are under Representation Concentration Pathway (RCP) 8.5 which assumes GHG emissions will continue to rise strongly through 2050 and then plateau around 2100. Climate Hazard Result for Project Location Unit Temperature and Extreme Heat 26.4 annual days of extreme heat Extreme Precipitation 4.90 annual days with precipitation above 20 mm Sea Level Rise 0.00 meters of inundation depth Wildfire 0.00 annual hectares burned Temperature and Extreme Heat data are for grid cell in which your project are located. The projection is based on the 98th historical percentile of daily maximum/minimum temperatures from observed historical data (32 climate model ensemble from Cal-Adapt, 2040–2059 average under RCP 8.5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi. Extreme Precipitation data are for the grid cell in which your project are located. The threshold of 20 mm is equivalent to about ¾ an inch of rain, which would be light to moderate rainfall if received over a full day or heavy rain if received over a period of 2 to 4 hours. Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi. Sea Level Rise data are for the grid cell in which your project are located. The projections are from Radke et al. (2017), as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider different increments of sea level rise coupled with extreme storm events. Users may select from four model simulations to view the range in potential inundation depth for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 50 meters (m) by 50 m, or about 164 feet (ft) by 164 ft. Wildfire data are for the grid cell in which your project are located. The projections are from UC Davis, as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider historical data of climate, vegetation, population density, and large (> 400 ha) fire history. Users may select from four model simulations to view the range in potential wildfire probabilities for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi. 6.2.

Exposure is rated on a scale of 1 to 5, with a score of 5 representing the greatest exposure. The adaptive capacity of a project refers to its ability to manage and reduce vulnerabilities from projected climate hazards. Adaptive capacity is rated on a scale of 1 to 5, with a score of 5 representing the greatest ability to adapt. The overall vulnerability scores are calculated based on the potential impacts and adaptive capacity assessments for each hazard. Scores do not include implementation of climate risk reduction measures. 6.3.
