Project presenter says retention pond will hold runoff with 'absolutely no discharge,' preserves trees
Summary
The project presenter told the board the site will preserve heritage trees and set aside roughly 15% of the property as natural preservation, and said the primary retention pond will retain the design rainfall with no discharge to downstream properties.
The project presenter told the board the development is designed to protect larger trees and to manage stormwater on‑site, saying the plans preserve heritage trees and set aside natural preservation next to neighbors. "We are preserving all of the the heritage trees on-site, which I believe are the trees that are 36 inches larger," the presenter said.
On stormwater, the presenter stated the primary pond is sized to contain the design rainfall and would not discharge to downstream properties: "...12 and 0.5 inches of rain is what the current design standard is. And that is retained within this pond with absolutely no discharge." He also said survey work from 2020 informed the drainage design and described which pond lies on which property.
The presenter acknowledged emergency overflow is possible in extreme conditions but emphasized the plan’s intent to treat and percolate runoff on-site and that the second, smaller pond is primarily on the adjacent property.
