I do a lot of new build inspections. Almost everyone of these homes is not graded properly with swales that don’t go towards the street. I need code because I’m dealing with builders and it is the only way to force them to do something. If the homes are close together then I can get them on the " The grade shall fall a minimum of 6 inches (152 mm)within the first **10 feet" from IRC as Texas (where I am) has adopted IRC to code here.
If I’m doing a larger home, the houses will often be greater than 20 feet apart, but still have a swale in between them and that swale is often not draining very much. Results are obvious; dead grass, mud, degradation of fences on property line. I’m looking for another code I could get the builders on in this situation. We do have one city around here that I found their city code requiring swales to be drained fully to the front of home, but not anything more than that.
The builders are able to fight me in other cities where I can’t force them to do it. I need to be able to make them re-grade or install drainage. Thanks
