Council Member Gennaro asks about the feasibility of implementing green infrastructure in areas with bedrock or high groundwater tables. Deputy Commissioner Licata confirms that detention systems can be successfully used in such conditions.

  • Detention systems and tanks work well in areas with bedrock or high groundwater
  • These systems have closed bottoms, preventing infiltration and not exacerbating groundwater conditions
  • They rely on controlled release into the sewer system through orifice size

Thank you for that.
2:07:02
In your testimony, you mentioned that green infrastructure can only be used where soil conditions allow infiltration.
2:07:08
But would you agree that other types of green infrastructure such as detention systems can be successfully implemented in areas with bedrock or a high groundwater table?
2:07:19
Kind of a good follow-up to what you just said.
2:07:42
Right.
2:07:43
Okay.
Angela Licata
2:07:23
Yes.
2:07:24
And that that is true.
2:07:25
Detention systems and tanks work really well because they have a closed bottom, so we're not relying on infiltrating.
2:07:32
We're not exacerbating the groundwater condition.
2:07:34
You're absolutely right.
2:07:35
Then we're really relying on the orifice size or the slower release into the sewer system.
2:07:42
Exactly right.
