Hello, For an owner budget, I need some rough advice on estimating how many catch basins need to be added to a new parking lot and what size the pipes should be to get them to the outlet pond. Doesn't need to be a complex calculation, just an approximation on empirical evidence.
The parking lot is about 1,670 square yards and has 3 areas that are all roughly (give or take) 50' x 100' each all kind of draining towards the center of each area. Any help would be appreciated.
