KS and KD Values in Table 1 - Cannot find

Species Factor (Ks): Trees: 0.2 (low) / 0.5 (average) / 0.9 (high) Shrubs: 0.2 (low) / 0.5 (average) / 0.7 (high) Groundcover: 0.2 (low) / 0.5 (average) / 0.7 (high) Mixed vegetation: 0.2 (low) / 0.5 (average) / 0.9 (high) Turf: 0.6 (low) / 0.7 (average) / 0.8 (high) Density Factor (Kd): Trees: 0.5 (low) / 1.0 (average) / 1.3 (high) Shrubs: 0.5 (low) / 1.0 (average) / 1.1 (high) Groundcover: 0.5 (low) / 1.0 (average) / 1.1 (high) Mixed vegetation: 0.6 (low) / 1.1 (average) / 1.3 (high) Turf: 0.6 (low) / 1.0 (average) / 1.0 (high)

Reviewers tend to forget that this credit applies to the area that is irrigated, which may not include all vegetated areas within the LEED boundary. I would provide a narrative that says something to the effect of: While there is a total of 474,804 sf of vegetated landscape within the LEED project boundary, the 110,321 sf noted in WEc1 represents that area which is irrigated. While we could add the additional 364,483 square feet of vegetated area to the form, it would show zero (0) water applied to that area for both the base and design cases, making the end result exactly the same.

If a species does not require irrigation once it is established, then the effective KS = 0 and the resulting KL = 0. Therefore, the total landscape area must be the same in the baseline and design cases, but the irrigated area does not have to be identical. However, note that any natural/undisturbed vegetation should be excluded from the calculations altogether.
