She became a member of the
municipal council of IJsselstein besides her job in May 2006, after her party had received one of the 23 seats during the
elections. She became
Alderwoman of Society in IJsselstein in April 2010, when D66 became part of the new
executive board. Because of her new position, she stopped her activities at her company and vacated her seat in the council. During the
2014 elections, she was again the of her party, which received a plurality in the council of five seats. She returned to the executive board as Alderwoman of People, a position with a portfolio highly similar to her previous one, with as special project "the customer at the center and deregulation". She stepped down on 8 February 2017 simultaneously with her colleague Vincent van den Berg (
CDA) because it was revealed that a cooperation between the municipalities IJsselstein and
Montfoort had cost €1.5 million more the year before than planned. This resulted in the fall of the executive board. Van Beukering's departure was planned thirty days later. Both municipalities had started to merge their
civil services in 2014 in order to decrease spending on their bureaucracies, but problems had emerged resulting in a need for an estimated €1.7 million to resolve them. A
motion of no confidence in the municipal council earlier had failed. During the formation of a new executive board, the
coalition fell as well, as D66 wanted resigned alderpersons to return, while this was unacceptable to the
VVD. D66, being the largest party in IJsselstein, formed a new coalition just over two weeks after the fall of the board. Van Beukering returned as Alderwoman of Economic Affairs. On 21 September 2017 she resigned from her position as alderwoman again together with two others. This had resulted in the CDA leaving the coalition. Van Beukering resigned after a number of parties with a majority in the council threatened with a motion of no confidence. In turn, the three resigning alderpersons declared that the council had become "sour" and was making it impossible for the executive board to govern. D66 subsequently passed the opportunity to form a new executive board to the second biggest party. Van Beukering was D66's in IJsselstein in the
2018 and
2022 municipal elections. == Post-alderwomanship ==
