Every New Landscape Gets a Water Budget. Here Is How to Meet It
California's MWELO law sets a water budget for new and renovated landscapes in Orangevale. Here is what that means for your plants, your irrigation, and your paperwork.

MWELO stands for the Model Water Efficient Landscape Ordinance. It sets a water budget for new and renovated landscapes across California, and that includes homes right here in Orangevale. The rule caps how much irrigation water a landscape project can use in a year. Most new landscapes of 500 square feet or more, and most full renovations of 2,500 square feet or more, have to meet this budget before the project gets final sign off. The number is not a rough guideline. It is a specific limit your landscape plan has to hit, and it shapes almost every choice that follows, from which plants make the list to how the irrigation system gets laid out.
What Counts as a New or Renovated Landscape in Orangevale?
Not every yard project triggers MWELO. New construction homes almost always fall under the rule, since the whole landscape counts as new. A full front yard or backyard tear out, where old turf and beds come out and new ones go in, usually counts too once the area passes the threshold. Smaller updates often stay under the limit and skip the formal review process.
- New landscapes of 500 square feet or more usually need a plan review
- Renovated or rehabbed landscapes of 2,500 square feet or more usually need one too
- Adding a few shrubs or a small garden bed typically stays under both thresholds
- New construction homes almost always count as new landscape, regardless of size
If you are not sure where your Orangevale project lands, the safest move is to check before design work starts, not after the plants are already picked out.
How Orangevale's Water Budget Number Gets Set
The budget is based on your landscape's size and the local climate. Orangevale sits in a hot, dry part of California, so the state's evapotranspiration numbers for our area factor directly into the calculation. Plants get grouped by water need into what the ordinance calls hydrozones.
- Thirsty plants share one hydrozone, so they do not pull water away from the rest of the yard
- Drought-tolerant plants share another zone with a much smaller water allowance
- Turf gets its own tight limit, since it uses more water than almost any other landscape choice
- Each zone runs on its own irrigation schedule, which keeps the whole yard inside the approved budget
Local weather data plays a bigger role in this number than most homeowners expect. A landscape the same size as one in a cooler coastal city gets a tighter water budget once it is calculated for Orangevale's summer heat, which is exactly why hydrozone planning and plant choice matter so much here.
Why the Budget Pushes Orangevale Homeowners Toward Drought-Tolerant Design
Turf is the thirstiest plant choice on the list, so a design loaded with lawn eats through the water budget fast. Most Orangevale homeowners find it easier to hit their number with a plant palette built around drought-tolerant landscaping in Orangevale, paired with efficient drip irrigation instead of old spray heads. Native and Mediterranean plants use less water once established, which gives the design more room to work with before it runs into the cap. A smaller turf area, grouped smartly with the rest of the yard, often gets a project under budget without making the yard feel bare.
Sacramento County's Review Process
Orangevale is unincorporated, so Sacramento County handles the landscape plan review, not a city planning office. Projects that meet the size threshold need construction level planting and irrigation plans submitted for review before work begins. Once the landscape is installed, a completion package goes back to the county before final inspection sign off happens. Sacramento County's landscape review page lays out the exact submittal steps and forms used for this process. Plans typically get reviewed within a few business days once a complete submittal package is in hand, which is one more reason it pays to get the water budget right before drawings are finalized.
What Happens If an Orangevale Plan Goes Over Budget
A design that comes in over the water budget does not just get rejected and forgotten. It goes back for changes, usually swapping in lower water plants, shrinking the turf area, or upgrading the irrigation efficiency until the numbers work. Catching this early, before construction drawings are finalized, keeps a project on schedule. Catching it late can mean reworking a plan that is already close to done, which costs time nobody wants to lose.
Orangevale homeowners who plan for the water budget from the very first design meeting almost always move through county review faster than homeowners who find out about it midway through.
Two Ways to Show Your Project Meets the Budget
MWELO gives homeowners two paths for proving a landscape fits inside its water budget. Larger or more complex projects usually work through the Performance Pathway, where a full water budget calculation is done for the exact plant mix, hydrozones, and irrigation equipment in the design. Smaller projects between the two size thresholds often qualify for the Prescriptive Compliance Option instead, a shorter checklist covering things like turf limits, mulch depth, and drip irrigation use.
Either path leads to the same goal, a landscape that uses water efficiently. The Prescriptive option just moves faster for projects that are already leaning toward low-water design, since there is less paperwork to review.
Getting Ready Before Your First Design Meeting
A little prep work before you sit down with a landscaper helps your project move through the water budget process without delays.
- Measure or estimate your total landscape area so you know which threshold your project falls under
- Decide early how much turf area you actually want, since it has the biggest effect on the budget
- Think about which parts of the yard get full sun and which stay shaded, since that shapes hydrozone planning
- Ask your landscaper to confirm whether your project needs Sacramento County plan review before design work begins
Homeowners who bring this information to the first meeting usually see a faster design turnaround, since the water budget gets built into the plan from day one instead of being checked at the end.
