Option 2. Natural Land Cover Conditions (3 points)

Calculate the difference between the projected runoff volume under the proposed design conditions and the runoff volume under natural land cover conditions that existed prior to any disturbance. Retain (e.g., infiltrate, evapotranspire, or collect and reuse) on site the increase in runoff volume using LID and GI practices.

For zero lot line projects only Project teams may combine on-site and off-site strategies to retain runoff from the associated percentile regional or local rainfall event for points according to Table 1. Engage with local or regional authorities to coordinate off-site rainwater management strategies that meet the credit’s intent, such as participating in community-wide rainwater management programs.
