The initial bear sighting was reported from the 3500 block of Fairpoint Street around midday.
Two of the bears were later seen rummaging through a garbage bin in the area.
The cubs were also seen swimming in a backyard pool, where the homeowner was able to chase them away.
California Fish and Wildlife said the three bears appeared to be a mother and her two cubs.
Very healthy looking mom and cubs in a tree and safe. Will wait until dark for quiet to try and haze them back to habitat. All good so far.— Cal Fish & Wildlife (@CaliforniaDFW) September 1, 2016
