Ward 11 Councillor Jeromy Farkas requested a report on the history and cost of water fluoridation from the city administration in preparation for a possible 2021 plebiscite. Relationship with housing industry Nenshi's policies of exercising greater city control over urban growth to manage urban sprawl is one of his key campaign promises. As expected, Nenshi's council has regularly collided with key associations of Calgary's housing industry. Frictions between the Nenshi council and key housing industry associations are an ongoing, overlapping, and escalating affair. Grievances continuously surfaced during the 2013 election, for example the "Cal Wenzel video", rumour-mongering about a pro-development slated council, and upcoming Wenzel slander lawsuit of 2014. Early in 2013, Nenshi's council suspended relations with the Calgary branch of the Canadian Home Builders' Association. The CHBA as a result was banned briefly from attending planning sessions. This action was conducted after the Calgary branch president Charron Ungar commented that the city was enacting a policy of "suburban freeze". Ungar commented upon a city plan which scheduled two suburb developments within 10 years. Nenshi declared that the CHBA and the Urban Development Institute (UDI) were representing the housing industry poorly after a controversial article was published by the UDI. The article suggested that minorities might not find suburban living comfortable. Nenshi suspended relations with the UDI soon after the article was published. Nenshi also felt that it was more expedient for the city to deal directly with the construction industry. Cal Wenzel housing lobby video In 2013, a video was leaked of Cal Wenzel, the CEO and founder of Shane Homes, speaking to panel of Calgarian home builders about a plan to influence the decisions of the city council after the upcoming elections. In the video Wenzel spoke of plans to raise $1.1 million to enlist the support of Preston Manning's conservative foundation the Manning Centre for Building Democracy. According to the speech, former Mayor Dave Bronconnier counselled Wenzel on how to control council motions with eight votes. “So for whatever and however, we have to ensure that we end up with the eight votes.” Wenzel proposed as a solution to circumvent direct confrontation with Nenshi's popularity. Wenzel named councillors the industry could rely on to support motions in favour of the lobby and he supported with donations. Nenshi has ordered a probe into what he described as distasteful and shadowy possible violations of electoral laws. In the wake
