San Diego County homeowners can receive $2.75 per square foot to replace their water-wasting turf lawns with sustainable landscaping under a new program in Southern California. The new Landscape Transformation Program was announced this week by both the San Diego County Water Authority and the Los Angeles-based Metropolitan Water District. “Over the past few years, the water authority has helped foster sustainable landscaping through financial incentives, a demonstration garden, hands-on classes and publication of a detailed guidebook,” said Mark Muir, chair of the water authority’s board.
