Utility Trenches in Pervious Pavement Section

[GJ1970]

I'm working to model a section of a private road with pervious pavement and rock storage to treat some stormwater runoff. The road is 26' wide. There are also some utilities running under the road as well. For the purposes of modeling exfiltration, would it be best to remove the utility trenches from the width used to compute exfiltration?

Thank you,

Sounds like you answered your own question. Assuming that the utility trench doesn't provide the same storage or exfiltration capability, it should probably be excluded from those calculations.
