Codenamed “Project Dark Monday,” the San Marcos City Council will consider an incentives agreement that would rebate an estimated $3.7 million in property taxes over the course of the deal, while the city would retain $11.5 million over a decade. The massive development comes at a crucial time for the local film industry, which is being affected by relatively low state incentives. For instance, AMC Networks Inc. recently opted to move filming for TV show “Fear the Walking Dead” out of the Austin metro to Georgia.
