To earn points, your building occupants must make at least 10% fewer conventional commuting trips than the calculated baseline. If some alternative commuting is already taking place at your project building, the credit does not require you to improve that rate by an additional 10%. For example, if your initial commuting assessment shows that 4% of commuting trips use alternative transportation, you only need to improve that number to 10% to meet the first threshold for this credit and earn three points. You are not required to improve 10% on top of your original assessment.
