New York Water Rebates

Long Island, New York Water Rebates

The Long Island Garden Rewards Program is run by the Long Island Regional Planning Council and reimburses homeowners up to $500 for installing rain barrels, native plantings, or a rain garden. It covers most of Long Island, which makes it broader than the town-specific programs. The 2026 application window opens May 18, 2026, and funding has run out fast in past years, so apply early.

How to apply

  1. Confirm you are a Long Island homeowner and your practice is eligible
  2. Apply once the window opens on May 18, 2026, at lirpc.org
  3. Check your plant choices against the program native plant list before buying
  4. Install the rain barrel, native plants, or rain garden and keep all receipts
  5. Submit receipts and photos for reimbursement of up to $500

What you'll need

  • Proof of Long Island residency
  • Itemized receipts for plants, rain barrel, or rain garden materials
  • Photos of the completed project
  • Plant list showing native species used

Pollinator Patch can help: It picks Long Island-appropriate natives for the coastal Northeast, designs an HOA-friendly layout that fits a rain garden or native planting, and assembles your plant-list and receipt packet for reimbursement.

Avoid these mistakes

  • Don't wait until late spring to apply. Funding ran out within weeks of opening in past years.
  • Don't buy plants before checking the program native plant list. Non-native plantings are not reimbursed.
  • Don't expect upfront money. This is a reimbursement program, so you pay first and recover costs after.
