Baseline energy usage emissions for residential land-use types are calculated using SJVAPCD's baseline metrics for energy use,which are 2.88 MT CO2e/DU/yr for natural gas and 2.98 MT CO2e/DU/yr for electricity use. The reduction achieved between this baseline metric and the Project emissions is applied to non-residential land- uses after removing the benefit for EnergyStar appliances from residential land-uses. 2. Project scenario represents emissions from the Project in 2020 as described in the report. 3.Consistent with SJVAPCD guidance,the percentage reduction was calculated as the difference between the Baseline and Project emissions divided by the Baseline emissions. 4.Shea Homes has committed to incorporating the following BPS measures into the Project. The percentage reduction associated with these BPS measures was taken from SJVAPCD's Final Staff Report—Addressing Greenhouse Gas Emissions Impacts under the California Environmental Quality Act."

For 1.0%reduction,a 1.0% neighborhood shall have internal and external connections to surrounding neighborhoods. Non-residential projects provide plentiful short-term and long-term bicycle parking facilities to meet peak season maximum demand.Short term facilities Bike Parking are provided at a minimum ratio of one bike rack space per 20 vehicle spaces. 0.625% Long-term facilities provide a minimum ratio of one long-term bicycle storage space per 20 employee parking spaces. 5.Vegetation sequestration numbers presented here have been amortized over 40 years. 0 Abbreviations: BPS-Best Performance Standards CO2e:carbon dioxide equivalents DU:dwelling.units MT:metric Ions yr:year
