Mr. Mayor, Madam City Administrator and City Council Members:
The Bay Area’s winter storm season began mildly with light showers on Tuesday and continued with a major storm front that passed through the Bay Area on Thursday bringing high winds and heavy rains. Wind gusts of up to 50 mph were reported, causing minor damage to trees and traffic disruptions throughout the city. Occasional heavy rains caused moderate flooding throughout Oakland.
PWA crews were extremely responsive. All calls were resolved by 5:00 p.m. Thursday, with the exception of one (Cherokee and Thermal see below). No emergency calls were received throughout the remainder of the evening.

Location of Problem Areas
All together, our crews responded to 54 locations for localized flooding/plugged storm drain inlets, sewer overflows and tree-related incidents. A detailed listing of these locations is attached for your reference.
The following two locations were the more serious incidents:
- Tree down at 14th Street and Willow fell into power lines causing a small fire. OFD, OPD, PG&E, and Tree Services responded and resolved without major incident.
- Cherokee Ave and Thermal sewer overflow. Sewer main collapsed. Crews worked overtime to contain spill, prevent the overflow from entering the storm system, and open up the sewer main. Crews performed an emergency dig and repair to the main today, December 2. Repairs estimated to be completed by December 3rd.
City Facility –Related Service Requests
A total of eleven (11) facilities had storm-related problems; 9 had roof leaks, 1 had a ground seepage leak, and 1 had a storm drain overflow problem. The majority of these have been patched and repaired, 4 locations still need further work to complete their repair. A detailed listing of locations is attached for your reference.
Number of storm-related calls received
- Trees: 14 calls responded to by 5 crews.
- PWA Call Center: 35 calls
- Sewers; Drainage; Streets/Sidewalks:
-
7 calls received directly; remainder of calls Routed from the PWA Call Center.
-
- Media calls: KDTV Univision 14
In summary, it looks like all of our pre-storming preparation have paid dividends since we did not have any major incidents of flooding, and only 32 calls for plugged storm drain inlets / localized flooding out of over 7600 inlets in our City. The storm-related facility problems are mainly due to deferred maintenance, which we continue to respond and repair on an as-needed basis. The supervisors and crews remain very responsive. I will keep you posted on any new developments should they arise.
