Reference guide v4 BD+C:Page290:
STEP 5:
I didnot understand why a 0.15 is used in this equation. Is this for any kind of losses in the rain water storage process. Cant we just use directly equation 3 to get adjusted LWR after equation 1?
Step 6:
0.15 in equation 4 is clear to account for 15% reduction by smart controls.

Hi Deepak,
We will be publishing an addendum to the PDF and print versions of the BD+C Reference Guide on October 1 that addresses this issue. Step 5, specifically Equation 2, should read: "Amount available = Gallons per 1 inch of rain x Average inches rain per month." The online Reference Guide already shows this correct equation.

Hello,
I still didn't get meaning of 0.15 in equation 4. Does it mean, for the additional 30% which mentioned in option 2, only maximum 15% can be supplied by either rainwater or smart irrigation control? In addition, I couldn't find the addendum for this topic in addenda database. Could you please illustrate more?
