Design and install a rainwater harvesting and storage system (including surface runoff and/or roof runoff) for landscape irrigation use or indoor water use. The storage system must be sized to hold all the water from a 1-inch rainfall event (equivalent to 0.62 gallons per square foot of roof area used for capture), taking into consideration the size of the harvest systems (i.e., 50% or 75% of total roof area, depending on the measure chosen from Table 10).

4.1 Indoor/Outdoor Water Use 9 Points
4.1.10 Collect rainwater as permitted by local code (Additional credit for distribution system that uses a renewable energy source or gravity).
Intent: Reduce water needs for irrigation by collecting and using rainwater.
Rainwater collection systems store rainwater for future watering and irrigation needs. Collecting rainwater keeps rainwater onsite, thus lowering the impact on storm water collection and conveyance systems and helping to replenish aquifers.

Guidelines for Level 1 Certification
Water Conservation is employed indoors and out, with measures ranging from low flow showerheads and water saving washers to xeriscaping and rainwater catchment.
Seven minimum standards including:
If installing gutters, downspouts must drain onto a pervious surface (turf or landscaping) or into a rainwater harvesting cistern.
Select any two (2) of the following water conservation strategies or install rainwater catchment system to provide for a minimum of 50% of landscape irrigation needs:
Strategy #1: Install an ENERGY STAR dishwasher.
Strategy #2: Select high performance fixtures.
Strategy #3: Zone irrigation system separately for turf and slab/bedding areas.
Strategy #4: Install a low-volume, non-spray irrigation system.
