Applicants may apply for both levels (passive and active) not exceeding $2,000 for the combination.

Incentive Level 1 - Simple/Passive (Rain Garden)
50% of the cost of eligible materials and labor up to $500

Practices: Passive earthworks include directing and retaining water in landscape using site appropriate practices such as basins, berms, terraces, swales, and infiltration trenches:

• surface, sub-surface, and conveyance features
• mulch, rocks/boulders for reinforcement (rock work) and soil amendments
• equipment rental such as tillers, jackhammers, and trenchers
• gutter and downspouts if rainwater is being conveyed to an appropriately-sized landscape feature
• rainwater harvesting design

Incentive Level 2 - Complex/Active (Rain Tank)
Rebate covers cost of system based on gallon per capacity up to $2,000.

• $0.25 per gallon capacity of 50-799 gallon rain tank
• $1.00 per gallon capacity of 800 gallon and larger rain tank

Practices: Rainwater storage tank with gravity-based supply use and overflow directed to landscape passive retention feature and/or passive rain garden.

• below- or above-ground tanks and conveyance plumbing including foundations
• filters and first flush systems

(Note: The installation of water tanks/cisterns may require a permit. Click here for more information.

The rainwater harvesting incentive program will not cover costs for the following:

• conveyance features which direct rainwater offsite without entering appropriately-sized landscape retention feature or staorage tank, e.g., gutter and downspout directed onto driveway allowing rainwater flow into street
• removing and replacing old gutter
• imported soil to create passive rain garden practices (creation of passive features does not require additional soil; engineered permeable fill can be covered if site requires it to support subsurface storage)
• purchase and delivery of gravel or decomposed granite (also known as DG or 1/4 minus) as a surface cover; decomposed granite includes finer particles which may result in sealing soil surfaces especially in desired infiltration areas
• purchase or installation of pressurizing pumps or associated controls (the incentive program is promoting lower costs and simple rainwater harvesting practices). Pumps are not prohibited; however, their associated costs will not be covered.
• purchase or installation of irrigation systems or backflow prevention devices
• purchase or installation of landscaping materials such as plants, edging, decorative gravel, etc.
• installation, raising, or improving a driveway
