A friend of mine asked me to complete the pre and post construction runoff calculations for this proposed 0.53 acre site. They are constructing a 45x70 metal building. The parking lot is existing, and other than that the existing pre-construction conditions are empty grass lot.
The county in question wants to see net zero increase to runoff, post construction. Any ideas? A detention pond for a development this size seems to be overkill.
There is a drainage swale on the north end of the property that runs the entire length to the main ditch by the road.
