One day after Boulder officials removed a map from its Web site that showed the locations of 60 medical marijuana cultivation centers in the city that were supposed to remain secret, a city spokesman said Friday that a second map containing even more detailed information was also accidentally made public.

The new map, which was removed from the city’s Web site on Friday, showed the locations of more than a dozen marijuana cultivation centers that are located in mixed-use zoning districts. It also called out the specific addresses of two sites just east of downtown Boulder.

“There was a second map on the online version (of a packet created for the Boulder City Council) and that has been removed from the Web site,” said Patrick von Keyserling, the city’s communication manager.

State law prohibits local governments from disclosing the location of so-called cultivation centers, and state lawmakers have exempted records that contain identifying information about the sites from the Colorado Open Records Act out of fear that would-be thieves might target large growing operations.

The city has now removed two maps in as many days that show the locations of cultivation sites in Boulder. Both maps were contained in a council briefing packet that was posted on the city’s Web site on Dec. 29.

But von Keyserling said the latest map to be removed is potentially a clearer violation of the state law that requires the sites to remain secret, because it contained specific addresses.

“Under the law for medical marijuana at this point, we are not supposed to be releasing publicly the specific address of a marijuana grow facility,” he said.

He said it’s less clear whether the city violated state rules by disclosing the first map, because while it showed detailed locations of growing centers, it did not call out specific addresses.

“The city attorney’s office will take a second look at that,” he said.

He said it remains possible that the city could re-release the map that doesn’t list specific addresses.
