Considerations for designing a rain garden
Start by look at the piddle draining from your mansion through your downspouts . In the best case scenario , the size of the rain garden should meet the size of the roof area that feeds into it . As an example , the house in the representative below has a footprint of about 1800 square foot . We estimate that a one-sixth of the cap , or 300 straight feet , drains to the downspout just off the drive .
To treat the runoff , the rain garden in the foreground of the illustration ideally should be 300 straight feet , too . You could make one big rain garden if you could direct several downspouts into it . However it ’s often easier to build a separate one near each downspout . That means you wo n’t have to lean long extensions to carry the pee . So , to manage water from another part of this cap there ’s a 2d rain garden near the back of the household in the upper correct hand corner of the illustration .
Bottom line : Any size rainfall garden is better than none . Even if they ca n’t arrest all of the water , the surplusage will flow out onto the lawn . Just make certain it wo n’t hang onto a neighbour ’s prop .
Choosing the best spot for your rain garden
To keep water from ooze into your cellar , rainwater garden should be at least 10 foot downslope from your foundation . The house above has underground tile to route the water flat into the front garden , and a wry current bed sends weewee to the back garden . Downspout extensions would also act for this . Do n’t put a rain garden over a septic field ; all of the supererogatory water system could overwhelm the drain arrangement . And if you already have a spot where water hoard , that ’s not a good location . pee puddling is ordinarily an indication of pitiful drainage .
You do n’t want your garden to breed mosquitoes , either . They need seven to 12 days to lay and hachure egg , so check that your water drain within 24 hours and you ’ll be ok . Before you install , regain out if your filth drains quickly enough : drudge a mess 6 to 8 inches bass and occupy it with water . If the water system does n’t drain away in a day , essay another spot .
