Planning a Low-Water San Antonio Landscape Around Caliche and SAWS Rules

The fall window closes October 15

The coupon is seasonal and the fall round is worth more than the spring one.

That is a $25 difference per coupon, and at the maximum of four coupons it is $600 this autumn against $500 next spring for exactly the same work. If a turf conversion is already planned for the next twelve months, the cheaper version of it is the one that applies before October 15.

What the coupon actually requires

1. Remove at least 200 square feet of grass per coupon. That is roughly the footprint of a single-car garage.
2. Existing landscape beds do not count. This is a turf removal programme. Converting a bed you already have earns nothing.
3. Remove the irrigation in that area too — sprinkler heads and drip lines within the 200 square feet come out.
4. The new bed must be irrigation-free. No permanent irrigation is allowed in it. A “xeriscape bed on drip” is not this programme, and this is the single most common misunderstanding of it.
5. Select 15 approved plants in any combination and plant them as one contiguous 200-square-foot bed.
6. Photograph everything, before and after, including sprinkler heads, valve boxes and drip lines. Photos are reviewed against the programme criteria.
7. Up to four coupons per SAWS residential customer.

Miss the criteria and the consequence is not just a refused coupon. Participants who do not meet the criteria are contacted with guidance and are ineligible for additional programmes until it is put right.

The call to make before you touch a sprinkler head

This is the part that costs people money, and SAWS says it plainly on its own page.

If you are removing enough irrigation to qualify for an Irrigation Design Rebate, you must schedule an Irrigation Consultation and receive a rebate offer before you do any work. Pull the heads first and the rebate offer cannot be made. The consultation line is 210-704-SAVE (7283), and if you already have a rebate offer from a consultation in the past twelve months, say so when you call.

The same rule governs the Outdoor Living Rebate in even blunter terms: no work started prior to the required pre-approval will be eligible. Both programmes are structured so the inspection comes first. In a city where the whole point is removing turf, the most expensive mistake available is removing it in the wrong order.

The Outdoor Living Rebate, and what disqualifies a project

Convert lawn into a deck or a pervious hardscape and SAWS pays a cash rebate of $300 to $1,000 after the work is completed and approved.

The artificial turf exclusion is worth reading twice, because plastic grass is often sold locally as the water-saving option. SAWS will pay you to replace a lawn with a flagstone patio. It will not pay you to replace it with artificial turf.

The cistern rebate, and the condition attached to it

$1.00 per gallon of storage, minimum 500 gallons, maximum $2,000. You may install a tank larger than 2,000 gallons; the rebate stops there.

The condition that changes the design is this: potable water backup is not permitted. The landscape the cistern serves has to survive on natural rainfall and harvested water alone. That is not a plumbing detail, it is a plant list decision made before the tank is ordered. Gallons are counted as total storage on the property, so several tanks add up toward the same rebate.

The process runs through a letter of intent, a site visit with a SAWS-approved rainwater harvesting consultant, an approved plan with an official rebate offer, and a final SAWS inspection booked on 210-704-SAVE. The finished cistern also has to be registered with SAWS under city code, which is free and online, and is the step most often forgotten after the tank is up.

The rain garden arithmetic worth knowing

SAWS publishes two numbers that fit together neatly, and together they size a rain garden without guesswork.

• A half-inch of rain on a 1,000-square-foot roof produces more than 300 gallons.
• A 200-square-foot area six inches deep holds about 750 gallons.

So a rain garden built at exactly the coupon’s minimum size, dug six inches deep, holds roughly the runoff from two half-inch rains off a 1,000-square-foot roof. The 200-square-foot bed the coupon pays for and the basin that actually manages your roof runoff are the same piece of ground, which is why SAWS points people at the Landscape Coupon to build one.

What the programmes add up to, and where the tax form appears

Run properly and in the right order, a single autumn’s work can draw on all three:

One consequence to plan for rather than be surprised by: SAWS rebates totalling $2,000 or more in a single calendar year require an IRS Form W-9, and the rebate is not issued until it is submitted. A cistern at the cap reaches that threshold on its own. If the timing matters to you, splitting a large project across two calendar years is a legitimate choice, and so is simply filling in the form.

Why this page does not quote a San Antonio xeriscape price per square foot

Because three conditions on your own lot move it further than any citywide average does, and a number that ignores them is worse than no number.

Caliche. Most Bexar County properties sit on caliche substrates, and the depth at which a bed or a basin reaches one is a site observation, not a lookup. It changes the excavation, sometimes the machine, and occasionally the design.

What the irrigation has to become. The coupon requires the 200-square-foot area to end up with no permanent irrigation in it. If one valve currently serves both the lawn and the beds you are keeping, that is a re-zoning job, not a cap on a lateral.

Which programmes the project is trying to qualify for. A patio built to 190 square feet earns nothing. Built to 200 square feet and 10 feet wide it earns up to $1,000. The rebate rules shape the design, so the design has to be priced after the rules are read, not before.

Can I put drip irrigation in a SAWS WaterSaver bed? No. WaterSaver landscapes must be irrigation-free. Sprinkler heads and drip lines have to be removed from the 200-square-foot area, and no permanent irrigation is allowed in the new bed.

Do I have to remove grass, or can I convert an existing bed? Grass. Existing landscape beds are not eligible; this is a turf removal programme.

How many plants does the coupon require? Fifteen approved plants in any combination, planted to create one contiguous 200-square-foot garden bed.

How much is the SAWS Outdoor Living Rebate? $300 to $1,000, paid as a cash rebate after the work is completed and approved. The project must be at least 200 square feet and 10 feet wide, must be pervious, and no work started before the required pre-approval is eligible.

Does artificial turf qualify for a SAWS rebate? No. Replacing turfgrass with artificial turf does not qualify for the Outdoor Living Rebate. Eligible materials are decking, flagstone, stepping stones and pavers.

How much is the SAWS cistern rebate? One dollar per gallon of storage, with a minimum of 500 gallons and a maximum rebate of $2,000. Gallons are counted as total storage on the property, and potable water backup is not permitted.

Do I need to register a cistern in San Antonio? Yes. Once built, a cistern must be registered with SAWS under city code. Registration is free and done online.

When should I call SAWS about an irrigation rebate? Before doing any work. If you expect to remove enough irrigation to qualify for an Irrigation Design Rebate, schedule an Irrigation Consultation on 210-704-SAVE (7283) and get the rebate offer first.

Will I get a tax form for SAWS rebates? Rebates from SAWS totalling $2,000 or more in a single calendar year require a completed IRS Form W-9 before the rebate is issued.
