Report
BACKGROUND AND DISCUSSION
There are approximately seven miles of unpaved levee access roads around the Plant's Oxidation Ponds and recirculation channels. The access roads have become overgrown with emergent vegetation which drifts into the ponds and channels, clogging integral pumping equipment and compromising the treatment process. Vegetation has also encroached on the levee crown, restricting staff access to certain areas. The City estimates that an initial four acres of vegetation will need to be physically removed to prepare additional areas for the ongoing monthly herbicide treatment events. This contract will include both vegetation removal efforts, removal of floating vegetation and monthly herbicide treatments to keep emergent growth from returning.
