The City of San Diego has adopted a Master Storm Water System Maintenance Program (MSWSMP) for flood control facilities in neighborhoods across the City. The Master Program will allow the City to better identify flood control channels requiring maintenance services over the next five years. Each fiscal year, the City will identify a small group of channels that have deposits of sediment and overgrowth of vegetation requiring maintenance to restore flood control capacity. The City will post information regarding channels selected for maintenance work on the Maintenance page.

• Addendum to Program Environmental Impact Report (PEIR)

  The addendum consists of the addition of two new storm water facilities ( Maps 64a & 130a) to the adopted MMP, the addition of two segments (Map 54) to a facility already included in the MMP, and technical corrections to three (Maps 52, 64, & 132) of the storm water facility maps included in the MMP.
