As we prepare for El Niño and the winter season, the City of Coronado is taking proactive steps to monitor conditions, maintain critical infrastructure, coordinate across departments, and ensure resources are ready when needed.

Strengthening Operational Readiness:

  • National Weather Service briefing with City leadership, management, and EOC staff
  • Internal EOC coordination and refinement of response plans
  • Mayor and Councilmember emergency plans and procedures review

Enhancing Storm Response Capabilities:

  • Sandbag distribution planning
  • Road and intersection closure planning
  • New: Operational Parker Pump Station, temporary drainage system at Five Points, waterproof SDG&E switch at 1st and A, and movable barricades for hard intersection closures

Reinforcing Regional Coordination:

  • Continued coordination with regional partners
  • Upcoming Council discussion on emergency communications, including physical notification infrastructure, the new emergency communications app, training, and transparency around how the system will be used

Expanding Community Awareness:

  • Launching a coordinated communications effort in the coming weeks, including PSAs, Project Coronado page, and digital and print outreach to support storm preparedness


Severe storms can cause floods, uprooted trees, and downed or broken utility lines in almost any neighborhood. During rainstorms, Coronado's first responders will focus on life safety. If roads are closed due to flooding or other incidents, the closures will be posted on this webpage and on the City's social media sites.

  • For all emergencies, call 911.
  • To report downed tree limbs, clogged storm drains, or localized flooding, call 619-522-7350.


City of Coronado's efforts include

  • Year-round City crews sweep the streets daily, conduct ongoing storm drain cleanings, routinely inspect the stormwater pumps, and clean the drainage channels to allow stormwater to flow properly.
  • During each rainstorm, crews will monitor and clean catch basins to keep rainwater flowing and to prevent flooding.
  • Emergency crews will be dispatched throughout the City during severe rain events.
  • The City has back-up stormwater and sewer pumps which are ready to be deployed to flooded areas.
  • At the City's largest Parker Pump Station, which is responsible for collecting stormwater and wastewater sewer flows, a fully functional storm water pump system is in place and ready to be powered on when heavy rains begin.





  • Monitor the weather and news, and sign up for alert notifications for your phones.
  • Sweep and pick up debris, leaves, and grass clippings around storm drains and curb gutters near your home. If you see clogging of the storm drain and it can be safely cleared, please remove it.
  • Keep lids securely closed on trash and recycle carts when placing them out for collection. Place carts 2 to 3 feet away from the curb to avoid impeding stormwater flows on the street. .
  • Have a flashlight and batteries ready for power outages. (SDG&E Power Outage webpage)
  • Turn off irrigation to save water and minimize runoff before and after rain.
  • Know the safest routes to and from your home or property should flooding occur.
  • Slow down and do not drive, ride or walk through flood waters.
  • Do not open or lift manhole covers in the event of street flooding.
  • Stay away from downed power lines. Call 9-1-1 to report them.
  • If told to evacuate, or if you feel unsafe, leave immediately.
  • Prepare your pets.






The City recommends stocking up on sandbags at local home improvement stores or online retailers if you have concerns about flooding. In the event of a major storm, additional drop locations may be utilized depending upon location of flooding. For questions about sandbags, please call the Public Services & Engineering Department at 619-522-7380.

The primary sandbag distribution locations will be self-serve at:

  • Bandel Park (corner of 10th Street and J Avenue
  • Cays Park Parking lot, 101 Grand Caribe Causeway

Sandbags are available to Coronado residents only. Please note:

  • Limit of 10 sandbags per household.
  • Proof of residency required.
  • Sandbags are available while supplies last.
  • Please be aware that removing sandbags staged at City facilities is prohibited.


How to Use Sandbags

  • Create a small dam or wall using sandbags to block or divert floodwater.
  • Sandbags should be stacked similar to a brick wall, using a staggered pattern. Build your wall at least two bags high.
  • Please do not drop off sandbags at city sandbag locations.
  • Consider storing your sandbags in a dry area until the next storm arrives.
