Dear Sir or Madam,

Thank you for contacting the Oakland Call Center, but additional information will be needed before your service request can be processed. Can you please give an accurate address of where the items have been dumped? Where exactly is this pile of litter box debris? Is there a landmark that can be used to help our staff better located this dumped substance.

Thank you

Oakland PWD and Waste management do handle hazardous waste. Alameda Co is Oakland's CUPA. Try contacting Alameda Co environmental heath 567-6700 to see who is responsible for cleaning this up. The PWD call center does not seem to have clue where to route hazardous waste issues.

So the earlier "addressed issue" post really meant " we couldn't find it so we closed it" nice.

Or they found it and chose not to deal with it.

Two Points:
1. Since there aren't any buildings or a specific address, I took great care in placing the cursor on the map and also described the location as carefully as possible. That is, on the south side of Lake Park adjacent to the sidewalk on the decomposed granite surface and about 100 feet east of the entrance to the parking lot under the freeway. As an additional point of reference, it's almost directly across the street from Heart and Dagger.
2. Coincidentally, a pest control contractor came out to inspect Splash Pad Park's rat problem today and he thinks the pellets are actually from a pellet-burning stove but I'm not sure either way.

Hope this helps.
