The Water Budget Area is the Total Lot Area minus the Building Footprint, Walkways, Hardscape (e.g. sidewalk, pavers, or driveway), Exemptions (e.g. edible gardens or retention ponds),
and Artificial Plant Material areas.

WATER BUDGET CALCULATOR
Hydrozones are a portion of the landscaped area which has plants with similar water needs grouped together that are typically irrigated by one valve or station with the same irrigation
type.
When different plant factors are grouped in one hydrozone, the highest plant factor determines the hydrozone water use category.
For example, 0.1 and 0.3 plant factor species hydrozoned together would be placed into the low, or 0.3, hydrozone water use category.
Another example, drip irrigation with temporary overhead irrigation would be placed into the drip irrigation's hydrozone water use category.
Bare mulch areas are included as part of its adjacent hydrozone to account for any future plantings in that area.
