New financial incentives are available for homeowners who want to replace water-hungry lawns with more efficient landscaping, the San Diego County Water Authority announced Wednesday. The agency has $500,000 available from grants awarded by the state Department of Water Resources, and an upcoming grant is expected to add another $600,000. Qualified applicants can receive up to $1.75 per square foot toward eligible project costs for upgrading 500 to 3,000 square feet of existing turf areas, according to the Water Authority. Funding for incentives is limited, and will be reserved for completed and approved applications on a first-come, first-served basis.
