Does your Benicia yard or sprinkler redo have to meet MWELO?

Your Benicia yard project only has to meet MWELO, California's Model Water Efficient Landscape Ordinance, if it needs a building permit, plan review or design review from the city. The city's MWELO page then applies it by size: new landscapes of 500 square feet or more, and rehabilitated (redone) landscapes over 2,500 square feet.

A lot of yard work is repair: a valve that won't close, a zone that won't run, a lawn that browns in the same spot every summer. A repair that needs no permit or review isn't what the ordinance is aimed at. The case to check is the bigger job: a whole yard redone at once, or new landscaping that's part of a remodel or addition with a permit already open.

What is MWELO and who has to follow it in Benicia?

MWELO is a statewide model law the California Department of Water Resources created in 1993, as the city's page explains. It sets minimum water efficiency standards for how a landscape is designed, built and kept up. In Benicia it sits with the Building Division, and the page lists two conditions that must both be true:

1. The project needs a building permit, plan review or design review. That covers single family and multifamily homes, as well as public and commercial sites.
2. The landscape area is big enough: 500 square feet or more of new landscape, or more than 2,500 square feet of existing landscape being rehabilitated.

So a new house with a 600 square foot front yard is in. The rules are tied to work that needs a permit or review, and whether your job needs one is the city's call. The city's page also posts an exemption form. If you think your project is outside the rules, ask the Building Division (building@ci.benicia.ca.us) before you plan around that assumption.

How do you measure landscape area for MWELO?

Benicia's prescriptive form defines total landscape area as every irrigated planting area, plus turf and water features. It leaves out the building footprint and hardscape such as sidewalks, patios and driveways.

That means a 4,000 square foot lot might hold well under 2,500 square feet of landscape once you take out the house, the drive and the patio. Measure the planted and lawn areas only.

What does Benicia's MWELO checklist require?

Projects between 500 and 2,500 square feet can use the short route, the city's Prescriptive Compliance Pathway Form. Larger renovations use the performance route, which needs a full set of plans: hydrozones, grading, irrigation and planting, plus a water budget worksheet and a soil report. The short form asks for:

| Item | What the form asks | What it means in your yard | | --- | --- | --- | | Compost | At least 4 cubic yards per 1,000 square feet, worked 6 inches deep, unless a soil test says otherwise | The soil gets amended before anything is planted | | Mulch | A layer at least 3 inches deep on bare soil in planting beds | Every bed is mulched. Lawn is the exception | | Plants | At home, 75% of the area in plants that need little or no summer water, and no invasive species | Most of the yard is drought tolerant planting | | Lawn | Turf, thirsty plants and water features together no more than 25% of the area | A lawn still fits, sized as one part of the yard | | Slopes | No turf on a slope steeper than 1 foot of rise in 4 feet | Steep banks get plants and drip, not grass | | Narrow strips | No turf in parkways under 10 feet wide, and any area under 10 feet wide watered with no runoff or overspray | Side strips and parkways go on drip or subsurface lines | | Controller | Automatic, using weather or soil moisture data, with a rain sensor | A smart controller, not a plain timer | | Pressure | Pressure regulators so the sprinklers run within the maker's range | No misting heads from too much pressure | | Shutoff | A manual shutoff valve as close as possible to where the system connects to the water supply | One valve shuts the whole system off | | Heads | Sprinkler heads and emitters that meet a national standard for even coverage | Matched, rated heads, not a mix of leftovers |

The property owner signs the form.

Can you still have a lawn in Benicia under MWELO?

Yes. On a home, the short form allows turf, high water plants and water features to share up to 25% of the landscape area. On a 1,600 square foot landscape that's 400 square feet, enough for a real play lawn if the rest of the yard is planted for low water.

The form also rules out turf on slopes steeper than 1 in 4 and in parkways narrower than 10 feet. On a sloped Benicia lot that puts the lawn on the flattest part of the yard. Our Benicia page explains why the hillside clay here sheds water and how short cycles with a soak between help.

What sprinkler setup meets Benicia's MWELO rules?

Read together, the checklist's irrigation lines describe a smart controller with a rain sensor, regulated pressure, drip in narrow beds and strips, and one shutoff near the supply. When we convert spray zones in beds, each bed gets its own valve, a filter, a pressure regulator and an emitter at each plant. Our drip conversion page walks through how that change happens, and drip vs sprinklers helps you decide which parts of the yard suit which. For the controller, see sprinkler controller replacement, which covers weather based models and setting them up.

The rebates can help with the same parts. The city's Benicia Saves Water page lists a smart controller rebate of 50% of the cost, up to $300 from the Solano County Water Agency, which the city matches while funds last for up to $600 combined.

Is a lawn rebate the same as MWELO approval?

No. They're two separate approvals from two different offices. The turf rebate is run by the Solano County Water Agency with a City of Benicia match. The city's page says the combined amount can reach $3,000 for a home, artificial grass and concrete don't qualify, and the project must be approved before any grass comes out. MWELO is handled by the Building Division, and only when the project needs a permit or review.

A lawn swap with no permit can need the rebate approval and nothing else. A large permitted redo may need both. Our rebate finder shows Benicia's programs beside the other Solano towns.

What happens when a Benicia MWELO project is finished?

The city's page lists the closing paperwork. For a prescriptive project that's a Certificate of Completion, an irrigation scheduling worksheet and a maintenance schedule for the landscape and irrigation. Request the landscape inspection at least 10 days ahead by emailing building@ci.benicia.ca.us. Performance projects also need an irrigation inspection, requested the same way.

What to do next

Measure your planted and lawn areas, note whether the work comes with a permit, and ask the Building Division whether MWELO applies. If it does, bring the city's checklist when you compare installers, so each quote shows the controller, the pressure regulation and the drip zones it calls for. Our sprinkler and drip repair and installation page covers new systems as well as repairs.
