Board Chair Kathleen Lonergan read aloud a detailed scope of work from Environmental Solutions describing targeted removal and disposal of several dead or dying bushes around wetland NWRA‑33, selective cutting of two dead oak and maple branches, attempts to knock back vines by cutting at water level and selective herbicide use, and hand‑pulling of standing weeds in sloped transitional areas.
Lonergan read: “The task is for removal and disposal of several dead or dying bushes around the perimeter and wetland NWRA‑33, specifically including the two dead oak and maple tree branches, southwest portion of the area, adjacent to water lilies. We will also attempt to kill back the vines on the north side and southeast site by both cutting at the water level and selective use of herbicide. We will not be able to eliminate the vines because they are up in the canopy, but we will be able to knock them back meaningfully. While we are onsite, we will also remove and or spray a small invasive in the buffer perimeter that sprouted up since our last task in the wetland area. This work area is the transitional adjacent to the grass backyards and has standing although dead leaves. Care crew has not been able to mow down the dead leaves because of the slope when equipment is placed on it. We will hand pull the weeds, standing weeds and weedwack as needed.”
District Manager Chuck Adams explained the ES approach involves more handwork and is likely to be more aesthetically pleasing, whereas A‑Z's forestry mulcher grinds everything. The Board noted that the District Engineer coordinated with Environmental Solutions and that the engineer — who was not present — will determine whether crews may cut back trees and which trees (larger than 5 inches in diameter are restricted) may be removed. The Board previously approved ES’s proposal subject to amendment; the corrected scope was resubmitted and work inside NWRA‑33 will proceed under the engineer’s oversight.
