Stormwater will be released at or below historical <br /> pre-development rates by utilizing a detention pond and culvert that discharges through vegetated <br /> undisturbed ground. The vegetation will filter out sediments and improve the water quality of water <br /> leaving the site. <br /> N <br /> N <br /> O <br /> N <br /> CO <br /> N <br /> c-I <br />
