Rainplan funds the design, permits, construction and ongoing maintenance of green stormwater improvements on qualifying DC commercial properties. Your cost is $0, and there is nothing to repay.
$0 owner outlay · not a loan · no obligation after the call

Paver systems that upgrade the look of your surfaces and drink the rain that falls on them.

Planted roof systems that turn unused roof area into working, good-looking infrastructure.

Planted retention gardens that capture and filter rain where it lands, and read as landscaping because they are.

Clean, well-placed storage that captures roof runoff and puts it to work on irrigation.
Repaving. Regrading. Drainage corrections. Retaining walls. Where the numbers support it, the problems you've been putting off get solved inside the funded scope.
A six-figure capital improvement can land on your property without touching your capex budget. Upgraded, maintained sites show better to tenants, brokers and lenders.
Completed projects earn discounts on the stormwater charges on your DC Water bill, based on the retention the project achieves. Savings recur every billing cycle.
Designed by experienced civil engineers and landscape professionals, and kept healthy by our maintenance program at no charge to you.
Measurable stormwater capture protecting the Anacostia watershed. Real material for tenants, community relations and sustainability reporting.
Owners who said yes, and what showed up.
A bioretention rain garden and infiltration system running the length of a working taxi lot, designed by licensed DC engineers and built in one season. The lot stayed open the entire time.
An abandoned play area's concrete boundary became a bioretention facility, gravel swale and rebuilt retaining walls, delivered end to end in nine months. The co-op keeps the water bill savings and the upgraded grounds; the Anacostia watershed keeps the car oils and metals out.
A nursing home campus with severe stormwater and drainage challenges was transformed through a facility-wide system of more than ten stormwater practices. Interconnected rain gardens carry water from one system to the next as it moves through the site, while creating attractive native landscaping throughout the campus. Engineering, construction and planting were delivered at no cost to the facility.
We explain why your site qualifies, show its numbers, and answer the obvious questions.
Our engineering partner walks the property around your operations.
Engineering and financial diligence determines what can be built, funded and included for you.
Scope and terms in writing before you sign anything. Then we build, and we maintain.
No commitment after the first call. No repayment from you, ever. No maintenance burden on your staff.
The credits. DC requires new development to manage stormwater, and lets developers buy Stormwater Retention Credits from properties that retain it for them.
Your property can generate those credits. We fund the project up front with our own capital and earn our return over years as they sell.
Everything else. The completed improvements stay with the property.
The utility savings stay on your bills.
The maintenance stays on our calendar.
Commercial, institutional, religious, multifamily or nonprofit property inside Washington, DC, with meaningful hard surface: parking lots, large roofs, paved courtyards, compacted lawn. Properties that already have drainage, flooding or repaving needs are often the best candidates. We fund a limited number of projects per cycle, and the review tells you in fifteen minutes whether yours is one of them.
Developers and consultants with a retention obligation to meet: Rainplan sells certified credits from projects we have built and helps you register the transfer with the Department of Energy and Environment. Tell us the volume and the compliance period you need.
Ask about buying creditsNothing. Rainplan pays for engineering, permits, construction and ongoing maintenance with its own capital, and there is no repayment. Our return comes from selling the Stormwater Retention Credits the project generates.
It is not a loan and there is nothing to repay. The agreement gives Rainplan the right to the credits the practice generates and to maintain it for the agreed term. You see every term in writing before you sign, and we encourage you to have counsel review it.
A tradable credit created in Washington, DC when a property voluntarily retains more stormwater than required, by installing green infrastructure or removing hard surface. Developers who cannot meet their retention requirement on site buy credits to comply. The program is run by the Department of Energy and Environment.
Rainplan does, for the life of the agreement. Maintenance is part of what keeps the credits valid, so it is in our interest to do it well.
From first call to finished construction is typically several months, depending on permitting and the size of the site. The Southern Homes and Gardens project went from start to completion in nine months.
Construction is phased around how the site is used. The Yellow Cab lot stayed open the entire time. We walk the sequencing through with you before anything is scheduled.
The fastest way to know is the fifteen-minute review. We have already run most commercial parcels in the District, so we can usually tell you on the call whether the retention numbers work for your site.
In a 15-minute property review, we'll show you why your site was identified, what could be built, and what we may be able to fund. No application. No obligation. No repayment.
We fund a limited number of DC projects each cycle. Starting the review now gives your property the best chance in the current one.
