San Diego is bracing for significant rainfall this week, with city officials undertaking various flood-prevention initiatives, as the National Weather Service forecasted to see 1.5 inches of rain from today through Friday. The city's Stormwater Department has been proactive, placing "no parking" signs in vulnerable areas, cleaning storm drains known for debris accumulation, and conducting street sweeping efforts to mitigate pollutants from entering water bodies during the upcoming rains, the City of San Diego reports.

City workers are preparing to monitor over 46,000 storm drains across San Diego and will, for the safety of the community, possibly close roads prone to flooding in Mission Valley near the San Diego River, according to the City of San Diego, which also quoted Stormwater Department Director Todd Snyder stating, "As we prepare for upcoming rain this week, our dedicated City employees have been working to ensure that key stormwater infrastructure is well-maintained." Snyder highlighted the city's and residents' collaborative effort to reduce flood risk.

Following an unprecedented weather event on Jan. 22, 2024, San Diego has undergone extensive emergency maintenance on its stormwater systems. This prioritizes an 18-mile stretch of channels citywide, including 12 miles in the Chollas Creek watershed. As the storm approaches, these channels, cleared of debris over the past months, will be crucial in managing the rainwater expected later this week.

Alongside the physical preparations, San Diego has launched an educational initiative, mailing out thousands of brochures outlining crucial flood preparation strategies. Residents have been advised to collect litter, secure bin lids, conserve water, and remain vigilant about the safest routes in and out of their properties in the event of flooding. The City's Storm Patrol will be ready during the storm, addressing issues like temporary floodwaters and fallen trees, reports the City of San Diego.
