b. Grass areas exceeding a 4:1, or 25%, slope.
c. Grass areas that are not accessible by paved pathways and/or are restricted by physical barriers that prohibit accessibility.
d. Grass areas installed closer than ten feet to a street and/or in front entryways to residential neighborhoods or subdivisions unless associated with active recreational activities.
e. Grass areas that are not utilized for active recreational purposes.
E. Plant Cover/Dust Control
All disturbed, grubbed, graded, or bladed areas not otherwise improved must be landscaped, reseeded, or treated with a layer of inorganic or organic ground cover to help reduce dust pollution.
1. Ground surfaces in planting beds, planters, medians, or tree understory within a landscaped area that are not covered with shrubs, accent plants, vines, ground cover, or other vegetation from the Arizona Department of Water Resource’s Low Water Use/Drought Tolerant Plant List must be treated with an inorganic ground cover.
2. Unless maintained as
, all portions of a
not occupied by
,
,
, oasis areas, pedestrian circulation areas, or required landscape elements must be landscaped with vegetation from the Arizona Department of Water Resource’s Low Water Use/Drought Tolerant Plant List, reseeded with a native seed mix, or treated with an inorganic ground cover and maintained in a clean condition. All portions of a site including common areas, natural areas, and revegetated or landscaped areas are to continuously be maintained to remove populations of buffelgrass (Pennisetum ciliare).
3. Unless maintained as
, future
pads within a
must be temporarily landscaped with vegetation from the Arizona Department of Water Resource’s Low Water Use/Drought Tolerant Plant List, reseeded with a native seed mix, or treated with an appropriate inorganic ground cover and maintained in a clean condition. All portions of a site including common areas, natural areas, and revegetated or landscaped areas are to continuously be maintained to remove populations of buffelgrass (Pennisetum ciliare).
4. If vegetative ground cover is not intended, a minimum two-inch layer of organic or inorganic material (i.e., decomposed granite, rock mulch, or other material) is required as ground cover under and around the vegetation in landscaped areas to help cool soil areas, reduce evaporation, and retard weed growth. Existing areas of undisturbed
