Exhibit A <br />Vegetated swales — swales are shallow ditches that have gently sloping sides. Ina vegetated <br />swale, native perennial grasses are planted along the bottom and sides of the swale to slow <br />runoff, filter sediments, and remove excess nutrients. A swale relies on gravity to move water <br />and is designed to direct the water where you want it to go, such as flower or vegetable <br />gardens, to limit runoff and to trap silt and pollutants in surface runoff. In order for the water <br />to gravity flow, it is recommended that there be a minimum 2%slope from beginning to end. <br />Organic mulch should not be placed around any plants in the bottoms or sides of the swale. <br />Berms — berms are mounds of earth with sloping sides that are located between areas of <br />approximately the same elevation. Berms are constructed to direct or redirect water in order <br />to keep water from flowing off the property. <br />Grades — grades are surface grading of an area so that water collects and flows to a lower <br />elevation away from the water collection site. Regardless of surface characteristics, when <br />planning to add a grade for surface drainage, slope is the most important consideration. For <br />efficient drainage, paved surfaces are recommended to have a minimum 1% slope. Turf or <br />landscaped areas are recommended to have a minimum slope of 2%. <br />Rain Barrel/Cisterns— rain barrels and cisterns are storage tanks that capture runoff water <br />from downspouts from a non -permeable area catchment area such as a rooftop. Cisterns are a <br />larger version of rain barrels, with a larger capacity for rainwater collection and storage. Rain <br />barrels and cisterns must be connected to properly installed rain gutters and downspouts. In <br />order forthe rain barrel/cistern to qualify as a rainwater capture feature, the property must <br />have existing gutters around the full perimeter of the roof and existing downspouts for <br />adequate water collection. In the case of a partially flat roof, gutters and downspouts must be <br />throughout all pitched areas in order to qualify. Rain barrels and cisterns must be properly <br />installed and meet all local and regional requirements. Existing rain barrels and cisterns qualify <br />provided they have been properly installed and provide water to the conversion/project area. <br />Pre -Inspection Procedures —Turf Removal <br />Customer is to provide photos of the turf area to be removed as part of the application process. <br />Photos of project area (4 to 6) must reflect the current turf grass area at the time of applying. <br />Google Earth/satellite images will not be accepted in place of photos. Photos must be taken at <br />appropriate angles, with visible points of reference, and at a sufficient distanceto allow for <br />review <br />Pre -inspections will be conducted on 100 percent of total projects submitted. For commercial <br />or public agency applications, Metropolitan, via Metropolitan's inspection contractor, will <br />conduct the inspection at no cost to Participant Agency. For residential applications, <br />Participant Agency or its inspector will conduct the pre -inspection. <br />After an application is received and the information has been verified, a project cannot be <br />accepted and funding is not reserved until a "pre -inspection" is conducted by Metropolitan, <br />MWDOC, the Participant Agency, or by a vendor inspector. The pre -inspection is a means to <br />determine confirmation of eligibility. The pre -inspection process verifies that the project area <br />
