Hey April
Sorry to just get back with you.
Let me check with the Div. We made the revision to drainage plans replacing the rip rap
pads with PSH's and sent out updated plans. But I know there have been some issues in
various Div's with the PSH's depending on steepness of topo around structure, etc and
with re-concentration of flow out of the PSH and erosion. They seem to work best in
very flat terrain. This particular project site does have some steeper topo although in
the area of the outlets looks like with some excavation work could be flat enough. So,
the installation/construction will be important.
I will check with the Div and get back with you.
Thanks
Galen

Hey Galen. Wanted to follow-up on the subject project. Any new information regarding
the PSHs? If not, I'll have to place the project on hold. It the request isn't feasible, please
let me know. Thanks!
Thanks,

Hi Galen,
Review for the subject project is complete. Could you please provide comments
regarding the below stormwater concern?
1. Based on the contours and velocities, it is requested that the standard riprap
aprons are replaced with PSH's at both new pipe outlets.
Please let me know if you have any questions or concerns.
Thanks,
April
