Built Environment and Transportation measures emphasize strategies to acquire open space and agricultural land, reduce single-occupancy vehicle trips, reduce the distances County employees drive for their commute, increase electric vehicle infrastructure in the unincorporated county, encourage mixed-use and compact community design, and encourage and facilitate the ability for people to choose other modes of transportation such as walking and biking. In addition, the County is working to decarbonize its fleet by transitioning County vehicles to alternative fuels such as renewable diesel and shifting to electric cars. Measures in this sector will help the County achieve reductions of 6,020 metric tons carbon dioxide equivalent in 2020 and 233,758 metric tons in 2030.


Strategy T-1 – Reduce Vehicle Miles Traveled

Strategy T-2 – Shift Towards Alternative Modes of Transportation

Strategy T-3 – Decarbonize On-Road and Off-Road Vehicle Fleet

Strategy T-4 – Invest in Local Projects to Offset Carbon Emissions


The use of fossil fuel powered automotive transportation is the largest contributor to the unincorporated county’s GHG emissions. The unincorporated county’s rural and suburban nature is characteristic of dispersed development, low density population, and remote travel destinations, which together contribute to greater vehicle miles traveled by residents than in our region’s cities. In 2014 (the baseline year of data used by the CAP to estimate emissions) on-road transportation made up 45% of all emissions from the unincorporated county.
