So the thought here is that as the rain water comes down onto this parking lot, it's gathering in the parking lot and then it's finding its way through that hole in the curb and it's filling up this area of this little ditch that was there, and that ditch is then either running towards a retention pond or something along those lines or it's just a place where water can gather, like the same way that a retention pond is, and it's planted in such a way that the plants are ones that can be soaked or can be dry, so you have to use very particular plantings in a spot like this to make sure that they're not gonna all die if there's a particular dry spell and it doesn't fill with water, but also that they're not gonna all die if we get three big rainstorms in a row and the thing is soaking, soaking wet for a while, so from the bioswale, either it's flowing towards something like a detention pond or it's slowly letting that moisture penetrate through the soils, so you'd wanna really think about what those soils were like in order to let that happen, 'cause you don't wanna penetrate too fast 'cause you don't wanna saturate the system below, but you wanna make sure that it's actually getting rid of the water so that it has the ability to take on more water later, or it's also potentially evaporating away to the sky, so these are systems for dealing with storm water and if we start saying, well, we're gonna use bioswales, it's gonna be great, we're gonna get a LEED point, you know, we're gonna love it, well, that's great, but now, suddenly, we have this thing where the way I've just designed this, I've just added a good 25 feet between my two sets of parking lots. Do I have enough room for that? Is there site space for that?
