City basin is ponding too much water
Basin on Goshen Ave. will be dewatered and treated to allow water to percolate into the ground and avoid flooding this winter
VISALIA – It’s hard to think about flooding in the dry heat of summer, but the City of Visalia isn’t waiting until winter to fix a ponding basin in north Visalia.
On Monday, Aug. 12, city staff began working on the ponding basin located along Goshen Avenue, between Akers Street and Demaree Street, just south of Houston Avenue in Visalia. Public Works Director Nick Mascia said the basin is not percolating the water into the ground and it will need to be unclogged to prevent possible flooding of Goshen Avenue as well as nearby homes.
Before maintenance activities can begin, Mascia said a certified biologist will conduct a clearance survey of the project area for the presence of special-status species and nesting birds. Once it is determined that work can begin, the basin will be dewatered so that the bottom can be treated or “ripped,” which will restore the basin to its design capacity and allow the percolation of water to occur.
Invasive vegetation around the basin, including cottonwood trees, will be removed to prevent blockage of pumps and basin inlets. Reducing the vegetation around the basin will also reduce bio-fouling, which effectively seals the bottom of the basin, preventing percolation and reducing capacity. The remaining trees will be trimmed to reduce overgrowth.
“Ultimately, the maintenance and rehabilitation work will return the basin and surrounding area to its intended purpose. We appreciate everyone’s patience and understanding as we complete the work necessary to bring the Cobblestone Ponding Basin back to a fully functioning basin,” adds Mascia.
The project will take approximately one month to complete once started.
