Exhibit A Convert over -head sprays to drip, micro -spray, bubblers, or rotating nozzles; whichever is applicable; or • Cap sprinkler heads or remove irrigation equipment and hand -water • No overhead spray sprinklers are allowed in the completed project. No synthetic turf is allowed. No plants that appears to be turf are allowed. No plants categorized as invasive to Southern California are allowed. Areas which have already been converted are not eligible. Areas with structures such as decks, fire pits, etc. are not eligible. Consumers are responsible for complying with all applicable laws, codes, policies, covenants, conditions and restrictions. Program Recommendations • Installation of a smart controller is recommended • A recommended plant list is available. The converted area must be designed to capture rainfall through infiltration or on -site storage for reuse. Infiltration and rainwater capture has to be achieved using one of the following techniques: rain gardens, rock gardens, dry river beds, rain barrels, cisterns, berms, vegetated swales, or grades. Selected method should allow infiltration or capture of rainfall/runoff and not channel to impervious surfaces and must meet all local and regional requirements. Project must include at least one of the following components, whichever is most desirable or feasible for project area: Rain Gardens — a rain garden is a planted depression or a hole that allows rainwater runoff from impervious urban areas, like roofs, driveways, walkways, parking lots, and compacted lawn areas, the opportunity to be absorbed. Rainwater collects in the soil mix and ponding area and eventually seeps into surrounding soils over time. Plants are distributed throughout the garden. This reduces rain runoff by allowing storm water to soak into the ground (as opposed to flowing into storm drains and surface waters which causes erosion, water pollution, flooding, and diminished groundwater). Rock Gardens — a rock garden is a shallow depression filled with 1-3 inch diameter gravel. Rainwater is stored in the space between the stones and eventually percolates into the soil. Plants are distributed throughout the rock garden and there is no ponding area. Dry River Beds - a dry river bed or dry stream is an area designed to slow heavy flows from rainfall and correct erosion problems. It is made up of a shallow swale lined with stone substantial enough to withstand a serious downpour. Large chunks of stone are used to slow the speed of storm water and to prevent erosion. In a garden, the careful placement of water- worn stone, or river slicks, along a Swale is aesthetically pleasing and also provides an ideal place for plants.
