This technical memorandum presents an analysis of the air quality (AQ) and greenhouse gas (GHG) impacts that would result from the proposed storm drain improvements required for the Esplanade Collection Residential Project in the City of San Jacinto (proposed Project). On August 2, 2024, LSA prepared an Air Quality, Greenhouse Gas Technical Memorandum for the proposed Hewitt and Esplanade Residential Project, San Jacinto, California (LSA, 2024)1 for the proposed Project. However, on September 19, 2024, the Project applicant received a comment from the City of San Jacinto’s Associate Engineer, Keith Tolliver, stating that the proposed Project would require the installation of 1,300 linear feet of 24-inch diameter storm drain line in Esplanade Avenue, between the northwest corner of the site and the existing storm drain line F in San Jacinto Avenue, which was not previously considered in LSA’s Memorandum. This proposed storm drain improvement would occur during the grading phase analyzed in LSA’s Memorandum.
As a result of this required improvement, the AQ and GHG emissions that would result from installation of the 1,300 linear feet of storm drain line were calculated to determine if any thresholds would be exceeded.
CalEEMod Version 2022.1 was used to analyze the construction related AQ and GHG emissions of the proposed Project.
Table 1 shows the estimated construction schedule utilized in the LSA Air Quality, Greenhouse Gas Technical Memorandum, which was expected to last approximately 18 months for 6 days per week, beginning the third quarter of 2025 and ending in the fourth quarter of 2026.

Table 2 presents the trenching schedule, which is typically planned early in the construction phase, following grading. For a conservative analysis, a 10-day overlap with grading activities is assumed.

Regional Emissions
Table 3 shows the CalEEMod estimated Project emissions for trenching activity combined with construction emissions presented in LSA’s Memorandum. The estimated Project emissions include those generated both from on-site sources (such as off-road construction equipment and fugitive dust) and off-site sources (vehicle travel leaving and arriving to the site). As shown in Table 3, the construction emissions from the proposed Project with the trenching activities for storm drain improvements, would remain below the South Coast Air Quality Management District (SCAQMD’s) adopted regional thresholds.2 Table 3.

estimated construction LST emissions from trenching were combined with the rest of the Project’s construction LST emissions, as identified in LSA’s Technical Memorandum.
The localized impacts analysis, by design, only includes on-site sources. CalEEMod does not separate on-site and off-site emissions for mobile sources, so this analysis conservatively assumes that all area, stationary, and energy source emissions occur on-site. Additionally, 5 percent of project-related mobile emissions (estimated to represent on-site vehicle travel) were assumed to occur on-site. This conservative assumption reflects that most vehicle travel, and therefore associated emissions, would occur off-site.

As detailed in Table 4, the Project’s on-site construction LST emissions including emission from the storm drain improvements would not exceed SCAQMD LST thresholds. Given the relatively small scale of the Project, Basin-wide health effects are not assessed, as emissions are not high enough to warrant regional modeling.
Furthermore, no SCAQMD methodology exists to quantify health impacts from small-scale projects, making it speculative to assign health effects to emissions at this level. Based on this localized analysis, the proposed Project would not expose sensitive receptors to substantial pollutant concentrations.
Greenhouse Gas
The Project’s construction GHG emission estimates from trenching combined with the total construction emissions from LSA’s Technical Memorandum are shown in Table 5. Pursuant to SCAQMD methodology, the construction emissions are amortized over 30 years.
Table 5 shows that the Project would emit a total of 1,427.2 metric tons of carbon dioxide equivalent (MTCO2e) over the duration of Project construction including emission from the storm drain improvements.
Amortizing the construction emissions over 30 years results in an average of 47.6 MTCO₂e per year, which is an increase of 0.7 MTCO2e. This increase equates to 0.02 percent of the total GHG emissions that would be generated by the Project and would not result in an increase to the impacts that were previously identified.

Conclusion
The proposed Project's maximum daily regional and localized construction and operational emissions would not exceed SCAQMD’s regional thresholds of significance, as detailed in Tables 3 and 4. All construction activities would comply with the applicable SCAQMD rules and regulations, including Rule 402, Rule 403, and Rule 1113. Additionally, the Project’s GHG emissions would increase 0.02 percent with inclusion of the required storm drain construction, which would not result in an increase to the impacts that were previously identified.

6. Climate Risk Detailed Report
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 23.3 annual days of extreme heat Extreme Precipitation 3.30 annual days with precipitation above 20 mm Sea Level Rise — meters of inundation depth
Wildfire 8.49 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 (Radke et al., 2017, CEC-500-2017-008), and consider inundation location and depth for the San Francisco Bay, the Sacramento-San Joaquin River Delta and California coast resulting different increments of sea level rise coupled with extreme storm events. Users may select from four scenarios to view the range in potential inundation depth for the grid cell. The four scenarios are: No rise, 0.5 meter, 1.0 meter, 1.41 meters 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.
