• At this time, you can expect to hear back from a planner within 8-12 weeks of applying with the goal of getting a project approved for installation within 6 months of applying.

• The entire upfront cost of the project is the property owners’ responsibility. When the project has been installed and has passed the final inspection, a rebate will be issued based on the project type rebate metrics  as determined by the project size up to $7,500. RainScapes Rewards is not a grant program.

• An estimate of the rebate amount will be provided when the project is approved, based on the approved project size. Any enlargement to the project size should be approved by your RainScapes planner prior to installation if you want that area considered for a rebate.
• The rebate will be based on the total of all applicable paid receipts up to and not exceeding the determined rebate maximum, at the rate on the rebate schedule table (PDF).
• Sales tax will be excluded from the receipt total.

• To find out how much cost is covered see the Rainscapes Project Cost Table

• No, however the professional you choose to work with must meet our requirements in designing and/or installing your project type.

• Please review the project type rules and requirements section and the resources provided for additional guidance.

• Please refer to this resource: Make a Planting Plan (PDF)

• You will receive email notification from the RainScapes program that your project has been approved and for how much rebate your project qualifies. 
• The notification will contain a link to the Property Owner Agreement (POA), which you will need to electronically sign.  We cannot accept emailed or printed copies of the signed agreement.

• The Agreement specifies the general terms and conditions of the Property Owner’s participation in the RainScapes Rewards Program. An example agreement can be viewed here.

• You or your professional contractor will need to provide the required  plan documents within 3 months of receiving your site assessment report.  Once your project is approved for installation, you’ll have 6 months in which to install it and have it inspected for final rebate approval.
• You will receive a reminder email 30 days prior to the 3-month deadline if we have not yet received your plan. You can request an extension by contacting either your planner or [email protected].

• Planted projects can typically be installed between April and November but it depends on weather and the likelihood of frost or overly rainy conditions. More planting guidance (PDF). 
• Permeable pavement projects can be installed year-round provided the ground isn’t frozen. Water harvesting projects should be installed in spring, summer or fall as they typically need to be winterized over winter.

• No. Ask your RainScapes planner for assistance if you are unsure of the location of rights-of-way and easements. 

• Contact your RainScapes planner to schedule a final inspection. 
• At this time the final inspections are typically conducted virtually rather than in person.
• Be prepared to take measurements and photos of your project for verification of the project.

• Submit receipts
• Submit images and measurements if requested
• Digitally sign the Property Owner Agreement if not already done.

• Yes. The final rebate amount will be based on the total amount of acceptable receipts, up to the approved rebate amount for your project. Plants listed on the receipts will be checked against the plan and plant list that was approved and verified as installed.
• ​All receipts related to the cost of the project must be submitted, including proof of payment-in-full invoices for all work performed by others. When using an installation contractor, all work must be final and all payments made in full to the contractor before a rebate can be issued. Receipts issued for cash or electronic purchases, invoices marked “paid,” copies of cancelled checks, screen shots of electronic funds transfers (such as through third parties, like Venmo), or copies of bank or credit card statements (with sensitive information blacked out) are all acceptable forms of proof of payment.

• In general, the purchase of approved plants; materials, such as mulch, compost and stone; hardware, such as pipe and connectors; equipment rental, such as a tiller; design fees; and labor can be included as long as they pertain specifically to the project and there is proof of purchase. The purchase of tools and equipment, such as shovels, or wheelbarrows, cannot be included. If you are unsure, submit all receipts to your planner for a determination.

• No

• Typically, within 8-12 weeks after your final inspection.

• You will be eligible to apply for a reduction in the Water Quality Protection Charge (WQPC) that appears on your property tax bill. 
  • Upon project completion, you will be provided with information on how to apply for the credit. The RainScapes Program urges all applicants with completed projects to apply for this tax reduction. Visit the  WQPC site.
• The Property Owner Agreement permits access to your property by County staff to conduct an inspection of your project every three years. 
  • Enrolling in the WQPC Credit program can substitute for the in-person inspection by County staff for the follow up inspections. More information:  WQPC Credit program. 
  • Inspection access will be limited to looking only at the RainScapes projects or other stormwater management projects installed on the property to verify that they are still in place and functioning as intended.
• You are expected to keep your project reasonably maintained and property functioning throughout the year and for the duration. Maintenance needs generally decrease in 2-3 years for planted projects.
