Virginia Water Rebates

Fairfax County, Virginia Water Rebates

The Conservation Assistance Program (CAP) is run by the Northern Virginia Soil and Water Conservation District (NVSWCD) for Fairfax County property owners. It cost-shares conservation practices like rain gardens and conservation landscaping at up to 80% of project cost. The process starts with a free site visit. NVSWCD staff look at your property, determine eligibility, and only then do you submit a funding application.

How to apply

  1. Confirm you own property in Fairfax County
  2. Complete the electronic form to request a free site visit
  3. Host the NVSWCD site visit to determine eligibility
  4. Submit the funding application after a recommendation to apply
  5. Install only after Board and steering committee approval, then request the post-install inspection for reimbursement

What you'll need

  • Electronic site-visit request form
  • Funding application
  • Project cost estimates and plant list
  • Itemized receipts and after photos

Pollinator Patch can help: It picks Northern Virginia natives suited to a Fairfax rain garden or conservation landscape, designs an HOA-friendly layout that captures runoff, and builds the plant list and cost estimate for your CAP application.

Avoid these mistakes

  • Don't treat the site visit as an application. It is the eligibility step, and you apply only after a recommendation to apply.
  • Don't start installation before Board and steering committee approval. Early work cannot be reimbursed.
  • Don't skip the post-install inspection, which confirms the practice before reimbursement.
