As demonstrated above, default rural worker trip lengths for air basins in California vary from 10.8- to 19.8- miles, with an average of 16.47 miles. Furthermore, default urban worker trip lengths vary from 10.8- to 14.7- miles, with an average of 11.17 miles. Thus, while default worker trip lengths vary by location, default urban worker trip lengths tend to be shorter in length. Based on these trends evident in the CalEEMod default worker trip lengths, we can reasonably assume that the efficacy of a local hire requirement is especially dependent upon the urbanization of the project site, as well as the project location. Practical Application of a Local Hire Requirement and Associated Impact To provide an example of the potential impact of a local hire provision on construction -related GHG emissions, we estimated the significance of a local hire provision for the Village South Specific Plan ("Project") located in the City of Claremont ("City"). The Project proposed to construct 1,000 residential units, 100,000-SF of retail space, 45,000-SF of office space, as well as a 50-room hotel, on the 24-acre site. The Project location is classified as Urban and lies within the Los Angeles -South Coast County. As a result, the Project has a default worker trip length of 14.7 miles.14 In an effort to evaluate the potential for a local hire provision to reduce the Project's construction -related GHG emissions, we prepared an updated model, reducing all worker trip lengths to 10 miles (see Attachment B). Our analysis estimates that if a local hire provision with a 10-mile radius were to be implemented, the GHG emissions associated with Project construction would decrease by approximately 17% (see table below and Attachment C). Local Hire Provision Net Change Without Local Hire Provision Total Construction GHG Emissions (MT CO2e) Amortized Construction GHG Emissions (MT CO2e/year) 3,623 120.77 With Local Hire Provision Total Construction GHG Emissions (MT CO2e) Amortized Construction GHG Emissions (MT CO2e/year) % Decrease in Construction -related GHG Emissions 3,024 100.80 17% As demonstrated above, by implementing a local hire provision requiring 10 mile worker trip lengths, the Project could reduce potential GHG emissions associated with construction worker trips. More broadly, any local hire requirement that results in a decreased worker trip length from the default value has the potential to result in a reduction of construction -related GHG emissions, though the significance of the reduction would vary based on the location and urbanization level of the project site. This serves as an example of the potential impacts of local hire requirements on estimated project -level GHG emissions, though it does not indicate that local hire requirements would result in reduced construction -related GHG emission for all projects. As previously described, the significance of a local hire requirement depends on the worker trip length enforced and the default worker trip length for the project's urbanization level and location. 14 "Appendix D Default Data Tables."
