How Does Glendale California’s Turf Replacement Program Work — and What Does It Pay?

Glendale’s residential Turf Replacement Program pays $3 per square foot — up to $15,000 — to swap grass for natives that pull rainwater into the soil, not the storm drain.

Glendale Water & Power’s residential Turf Replacement Program currently pays homeowners $3 per square foot to replace turf with drought-tolerant and native plants, retrofit to drip irrigation, and incorporate on-site rainwater retention. A 5,000-square-foot lawn conversion reaches the $15,000 ceiling. That number gets attention — but the soil physics behind it is what makes the program genuinely interesting.

A turf lawn compacts over decades. Its roots stay shallow, and when Southern California rain finally arrives, the water has nowhere to go but the gutter. Native plants work differently. Their deeper, branching roots create channels that pull water downward into the soil rather than sideways into the drain.

What Glendale’s Turf Replacement Program Actually Requires

The program is administered through the Metropolitan Water District of Southern California. Homeowners must get pre-approval before removing any turf — it is a two-part application process. Overhead spray sprinklers must be replaced or modified. No hardscape is allowed except permeable hardscape.

The 3-plants-per-100-square-feet rule is the threshold that keeps soil from sealing back over. Bare dirt crusts. Roots keep it open. Synthetic turf is not an approved conversion option.

How the Water Infiltration Mechanism Works

The program’s core design goal is increasing on-site infiltration and retention of rainfall. When native plants establish, their root systems physically open the soil profile. Rainwater moves down rather than running off the surface.

Glendale explicitly requires rainwater retention or filtration features as part of each conversion. Permeable surfaces combined with plant root systems redirect stormwater back into the ground instead of the municipal drain network. This is the hydrological process that turf and paving spent decades dismantling.

A 1,000-square-foot conversion earns $3,000. A 5,000-square-foot conversion earns $15,000. Those figures assume the residential $3 rate — commercial sites run $2 per square foot under GWP’s current schedule, a different rate tier entirely.

The rebate amounts are subject to change based on program availability at the time of approval, so pre-approval timing matters. The ground remembering how to absorb rain is the durable result. The check is just what gets the shovel moving.
