Parking Lot Runoff and Erosion
Parking Lot Runoff and Erosion
(OP)
I have a large parking area, probably 1 acre in total. It was built adjacent to a river and is supported by sheet piles in some spots. My problem is runoff related. We have storm drains installed in this parking lot that go directly to the river. I am trying to divert as much of the runoff as I can away from these drains because this gravel parking lot is a huge source of sediment in the runoff. As I divert water away from this parking area, I still have to deal with the water that does make it into the gravel. What are some techniques for controlling the amount of sediment that gets into the storm drains? We've done check dams in the past but they silt up pretty quickly around here.

There aren't any methods that will not require some form of maintenance. Sumps in the inlets (with periodic cleaning) are most common for gravel parking lots in my area.

They are expensive though, but a requirement for many new larger developments.

The bottom 25% obviously assumes sediment, but the top 25% ensures freeboard conditions will occur in line with the flood I've designed for. This in line with the CIRIA document Design and Maintenance of Culverts which is widely used here in the UK.
