by As her nook of Kensington grew to become “a hotbed of teardowns,” Pam Marcus seen that the water accumulation in her yard had modified since she’d moved in 20 years earlier. After a storm in 2020, she referred to her yard as “Lake Marcus.” She reached out to Darlene Robbins with the Montgomery County Division of Environmental Safety’s RainScapes program, the arm that helps residents assess and mitigate stormwater points. Robbins, a RainScapes planner, estimated that 13 upslope properties drained into that one yard throughout vital rainfalls.
And Lake Marcus wasn’t simply an eyesore. Unmanaged stormwater may be harmful, doubtlessly inflicting property harm and stream erosion whereas additionally spreading pollution and creating breeding swimming pools for mosquitoes. The multifaceted resolution that Marcus’ waterlogged property required exhibits how landscapers, DIYers and even non secular communities are coming collectively to enhance the well being of our watersheds.
For county residents corresponding to Marcus, the RainScapes program affords sources and incentives to put in rain gardens, conservation landscaping, rain barrels, pervious pavement and cisterns.
To unravel her situation, Marcus employed Debbie Schweitzer of Kensington-based Shorb Landscaping, who really helpful a rain backyard with extra storage and controls. A rain backyard is a shallow melancholy, normally 8 inches deep, that fills with as much as 6 inches of water after a giant rainfall. It comprises native plantings that permit stormwater to be absorbed into the bottom slowly, reasonably than run uncontrolled into neighboring properties and streams.
A required percolation—“perc”—check confirmed that Marcus’ soil drained too slowly, so Schweitzer’s crew decompacted it and added berms to gradual and divert runoff to dry creek beds. Beneath these, PVC piping carries any extra water right into a 325-square-foot dry properly that fills solely when there’s extra water and permits it to perc slowly. One other pipe drains any overflow alongside the facet of the home into river rock on the entrance.
Including topsoil, Shorb then planted 1,400 sq. ft of conservation landscaping—all native vegetation. Their roots, that are a lot deeper than non-native turf grasses, take up rainfall higher and climate the new summers properly.

The county’s RainScapes program (Rockville, Takoma Park and Gaithersburg supply stormwater applications to their residents) syncs with a nationwide development to higher handle more and more dire stormwater occasions. “The previous method of establishing cities and cities was to maneuver water away from buildings and streets, however that has created environmental harm downstream,” says Luke Jessup, the proprietor of Father Nature Restorative Landscaping, a Wheaton-based landscaping firm. “All that sediment and particles and air pollution has broken our our bodies of water. We have to seize stormwater as near the supply as potential.”
With their filtering capability, rain gardens can scale back a number of pollution, says Ann English, RainScapes’ senior planner and program supervisor. When county residents construct massive additions, they’re required to incorporate inexperienced infrastructure instruments, corresponding to a inexperienced roof, a dry properly, a rain backyard and water harvesting, to deal with stormwater points. Dry wells, the most well-liked retrofit choice, don’t, nonetheless, filter water or promote native biodiversity. Rain gardens additionally “put water again within the soil, so it may step by step leak to our streams, which can hold them hydrated all summer time,” English provides.
“It labored amazingly properly,” says Marcus, a most cancers epidemiologist. For all that she did to correctly rectify the stormwater points in her yard, she spent about $46,000 and obtained a rebate of $6,375. Now she enjoys the birds, bugs and butterflies her native vegetation appeal to to her lake-free land.

The answer to Marcus’ points was advanced, however some residents tackle the development of a rain backyard as a DIY challenge. After admiring the seasonal pursuits created by three rain gardens at close by Olney Elementary College, Christopher Hinton-Miller and his spouse, Shani, needed to draw butterflies and hummingbirds to their yard, management erosion and enhance their view. Utilizing the RainScapes web site as his main information, he designed a 400-square-foot rain backyard and utilized to the rebate program.
Hinton-Miller, a mathematician on the U.S. Protection Division, obtained approval in July 2022 and had six months to finish building. That required renting a backhoe and consulting with a nursery to seek out deer-resistant vegetation. He stated it was a “lengthy, gradual course of” to dig, extract rocks and amend the soil with compost to create the 8-inch-deep ponding space they needed. He additionally constructed a driveway trench drain to direct stormwater to circulation from their gutters into the rain backyard.
Though he developed carpal tunnel syndrome within the course of, “it was therapeutic,” Hinton-Miller says, however he advises towards DIYing except you’re going to take pleasure in it. Their rebate, $3,750, was about $500 lower than what they spent. The challenge was a finalist for a residential BUBBA, or Finest City BMP (finest administration practices) within the Bay Award, given by the Chesapeake Stormwater Community.

“In the event that they’re doing it themselves, the digging half is a bit of overwhelming,” English says, so some owners choose to do conservation landscaping, which doesn’t require as a lot digging. Such landscapes that pond to a shallower stage of three inches, together with non-ponding conservation landscapes, also can qualify for RainScapes rebates. Much less digging means not disturbing the prevailing soil as a lot, which some environmental consultants encourage.

When putting in a rain backyard, “there’s loads that may go incorrect,” says Edamarie Mattei, founding father of Yard Bounty landscaping in Silver Spring. “When you don’t do it proper, you possibly can create a swamp.” Jessup advises hiring a landscaper with expertise. “We’re coping with ecosystems, and these are advanced organisms,” he says. “A whole lot of landscapers don’t actually perceive how advanced it’s.”
Kenzie Raulin opted for a hybrid technique for her small entrance yard rain backyard in Silver Spring. She employed Jessup to evaluate her yard, design the backyard, purchase the vegetation after which mildew the bottom as wanted. “Regardless that it feels expensive to rent somebody, it’s so definitely worth the experience,” says Raulin, who did the planting herself. “I’d by no means have give you the design that Luke [Jessup] did. There’s such worth within the expertise that folk have about forms of vegetation and easy methods to place them.” She additionally welcomes the number of useful flying bugs (not mosquitoes) that now frequent her yard, together with “praying mantises, backyard spiders and many caterpillars. It’s simply made the entire yard come alive.”

Some stormwater points are so immense {that a} home-owner alone can’t repair them. As an alternative, they require communitywide cooperation, just like the challenge that resulted from the collaboration of The Carolyn Condominium in Silver Spring, the downhill Mississippi Avenue residents, the Associates of Sligo Creek and the Chesapeake Bay Belief.
The tipping level for Benjamin “Sky” Brandt occurred in 2018, when storms brought on water to seep into his household’s basement, which had been resealed earlier. His neighbors had been complaining for years in regards to the flooding of their avenue, yards and houses, so Brandt determined to “observe the water.” He traced its circulation uphill to 2 30-foot black pipes pointed towards his avenue and fed by the massive roof and two parking numerous The Carolyn Condominium. “Folks don’t notice precisely how a lot water there’s when it rains on each sq. foot. It provides up actually quick,” he says. After taking movies and photographs, Brandt invited the Associates of Sligo Creek, the Montgomery County Division of Environmental Safety and neighbors to his house for a presentation.
Brandt took “compelling movies of the flooding,” says Package Gage, interim president of the Associates of Sligo Creek, who estimates seven homes have been impacted. Brandt and Gage contacted The Carolyn Condominium board, which “didn’t know there was an issue, and that’s typical. It’s not a blame factor in any way,” says Gage, who helped the condominium board acquire an indication watershed restoration grant for the challenge by the Chesapeake Bay Belief. The board supported the challenge.

Put in in 2019 on condominium property, the conservation panorama designed by Yard Bounty redirects and absorbs a lot of the water from one of many parking heaps. “The thought is you seize that water when it’s uphill and soak it into the bottom,” Gage says. The conservation backyard alone, nonetheless, couldn’t deal with all of the circulation. The runoff from the roof and different parking zone nonetheless wanted to be addressed, and the COVID pandemic had simply began. To get that second challenge—a deliberate rain backyard within the rental constructing’s yard—off the bottom, Brandt and Gage needed to apply for one more grant, persuade a brand new rental board, and discover an accessible contractor, which was tough in 2020.
As soon as the board realized the higher extent of the issue and that the potential repair had funding from the Chesapeake Bay Belief, they “have been actually enthusiastic about it as a result of it helps to beautify the property,” says April Scott, then the board president. “Now we have a big yard principally utilized by canine walkers, and the backyard simply beautifies the house. It wasn’t a tricky promote.”
Put in in the summertime of 2022 by Millersville-based Environmental High quality Assets, the rain backyard required an underdrain and underground storage unit to gradual the water’s downhill rush. Scott appreciates the piles of paperwork and the legwork accomplished by Brandt and Gage, and now enjoys the “busy train” of the rental’s inexperienced crew, which oversees the backyard. “That’s undoubtedly one thing I’ve loved, the teamwork, the collaboration between neighbors who wouldn’t normally know one another,” Scott says.

“To start with, all people was most likely simply seeing it as their very own situation,” says Brandt’s neighbor Paula Miller. “The challenge is a good instance of how people and organizations can work collectively to resolve these large issues.” Miller helps with the rental rain backyard weeding. And Brandt has put in 5 DIY rain gardens on his property. Earlier than and after congregants of the IMAAM Middle in Silver Spring put in a local plant backyard in 2022.

Whereas rain gardens have grow to be extra standard, some folks nonetheless harbor misconceptions. “Can my baby swim in it? Can I put lily pads in it?” Schweitzer says her purchasers have requested, not understanding that the shallow ponding (normally 6 inches at most) sometimes lasts lower than 48 hours. Appropriately put in rain gardens embody an overflow notch that drains into river rock, a second rain backyard on a decrease terrace, or conservation landscaping. Fast drainage eliminates mosquito breeding, one other frequent worry.
Some owners may fear that rain gardens are messy or muddy, however Bethesda resident Cindy Onder says her rain backyard “is the exact opposite.” When she and her husband, Nick, rebuilt their house in 2017, their landscaper on the time put in a rain backyard that turned out to be too sparse. In 2019, they employed Mattei to make it fuller and lusher. “It’s so lovely, …and I like that I’m doing factor for the setting,” Onder says.

Naomi Edelson, senior director of wildlife partnerships on the Nationwide Wildlife Federation, got here to view non secular congregations, which regularly have numerous lawned acreage, as contributors to native stormwater points and potential options. In 2014, the Takoma Park resident based a nationwide program throughout the federation known as Sacred Grounds that’s designed to steer congregations “to play a number one function in changing their garden or placing in native vegetation for wildlife habitat to assist folks and wildlife,” she says. “They’ve each massive acreage and the power to achieve lots of people. … We’re working with the idea of caring for creation.”
Edelson’s rabbi, Fred Dobb of Adat Shalom in Bethesda, first had the concept so as to add conservation landscaping to the congregation’s property in 2012, which led to a reference to the RainScapes program and a rebate. “All the initiatives we now do within the DMV have a stormwater hyperlink,” Edelson says. Certainly one of Sacred Grounds’ newest and largest initiatives, funded by the Nationwide Wildlife Federation and the Chesapeake Bay Belief, was with the IMAAM Middle mosque in Silver Spring.

For congregations, Sacred Grounds affords informational classes about stormwater and supporting wildlife. “Folks don’t notice the reference to their very own houses and the well being of the creeks or rivers close by,” Edelson says. Whereas they may really feel that they’ll’t make a lot of a distinction alone, “the congregation mannequin actually works. Individuals are doing it collectively and see that they are going to add as much as having an affect.” Congregants who attend the classes obtain a starter package of three to 6 free native vegetation for his or her yard, and Sacred Grounds provides the native vegetation for installations on congregation property.
Within the spring of 2022, the IMAAM Middle employed a contractor to dig out an 80-by-20-foot-long and 2-foot-deep space that had loads of compacted gravel. The congregants amended the planting space with richer soil and compost. (Resulting from easement points, the mosque wasn’t in a position to apply for a RainScapes rebate, however it obtained Chesapeake Bay Belief and Sacred Grounds assist.) As soon as the house was prepared, greater than 30 volunteers planted a whole lot of native vegetation. Their conservation landscaping captures runoff from a parking zone and close by Georgia Avenue. The mosque plans to use for a RainScapes rebate to remodel one other piece of their land.
Presently working with over 15 congregations within the DMV and 70 in whole, Edelson hopes to attach with church buildings and encourage them to contemplate rain gardens and conservation landscaping.

“Authorities companies are at some extent the place if we don’t do it at house and on our congregation grounds, they’ll’t get previous the place they’re” in coping with intensifying stormwater runoff points, Edelson says. “It’s our job to assist, and other people actually have responded to that idea.”
