Poggi Canyon Channel Maintenance Project

The San Diego Water Board adopted Order No. R9-2025-0071, Waste Discharge Requirements for the City of Chula Vista to implement the Olympic Parkway Poggi Canyon Maintenance Plan (Maintenance Plan), dated June 2024, to remove accumulated sediment and wetland vegetation from 13 established maintenance areas upstream and downstream of each of the inlet and outlet structures as well as storm drain outlets, which enter various areas of the channel. The Maintenance Plan describes the maintenance activities, including methods, equipment, and access and staging area location for each site, and establishes criteria for when maintenance is needed. Maintenance is expected to be conducted between September 16 and January 14 and occur annually or when criteria defined in the Maintenance Plan are met. Project activities will result in 0.69 acres of permanent ecological degradation impacts to aquatic resources under the jurisdiction of the San Diego Water Board. Those impacts will be mitigated with establishment of wetland aquatic resources.
