Storm Water Maintenance Prioritization and Survey
Thank you for your participation. The public survey is now closed.
A well maintained storm water system serves our community by protecting and improving water quality and reducing flood risk. The City of San Diego's Storm Water Division is developing a prioritization plan for storm water maintenance efforts. The plan includes an opportunity for the public to provide input on the selection of channels, basins, and structures to be included in the City's maintenance program. Through participation in the Storm Water Maintenance Prioritization Survey, the City will incorporate public concerns and input as part of the selection process along with evaluations of hydrology and potential impacts from flooding.
The purpose of this work is to maintain existing storm water facilities by restoring their original design capacity to provide public safety and protection of property. The City must routinely maintain the storm drain systems through periodic removal of trash, debris, vegetation and accumulated sediment.
Prior to any maintenance activity, a detailed analysis is conducted to identify:
- Where maintenance is needed;
- The best method to conduct needed maintenance; and
- The specific maintenance protocols that will be used to protect water quality and natural resources.
A detailed Hydrologic and Hydraulic Assessment (H&H) is performed to determine:
- The design flood conveyance capacity of the facility,
- The facility's current conveyance capacity,
- The sources and quantity of obstruction, such as accumulation of sediment and/or vegetation,
- The quantity of materials to be removed,
- The method of removal, and
- The amount of flood conveyance that will be achieved after maintenance.
The City is currently developing a new Municipal Waterways Maintenance Plan to replace the recently expired Master Storm Water System Maintenance Program. More information can be found here: https://www.sandiego.gov/stormwater/services/wmp
