Code requires native plant preservation and on-site water management as part of landscaping standards and environmentally conscious design practices. Code states that portions of ground-level open space that are not landscaped shall be surfaced in textured concrete, pavers, or other similar small-scaled materials with permeable characteristics. At least 25% of the total exterior site hardscape must be composed of pervious concrete or permeable pavers as part of a passive landscape water harvesting system. Landscape depressions and curb openings shall be provided to allow water to flow into and out of curb side planters. Each development has to include five or more environmentally conscious design practices, like shading at least 70% of parking and pedestrian areas; providing solar panels on roof or shade structures, providing a green roof with 4 inches of growth; providing permeable paving adjacent to planting areas; and providing vegetated green walls.
