Stormwater Infiltration
Stormwater Infiltration
(OP)
Two Questions..
1) Is there a reccomended rate or range of rates of infiltration when using structural fill?
2) Are allowable/acceptable infiltration rates for recharge governed by local ordinances or the BMP Manual? Site is in PA
Thanks!

RE: Stormwater Infiltration
The infiltration rate will depend on the surrounding (native) soil, and not on the structural fill. There are no "recommended" rates. It all depends on the soil and groundwater conditions of the particular site.

Of course, if your inflow is so high that a level-pool will not form, you would need to perform a more complex mounding analysis within the stone itself. But if your flow is that high, stone storage may not be adequate for your site.
