Count Olizar inherited the Korostyshev estate after his father's death in 1816 and actively managed it, engaging in public life, particularly as a supporter of the emancipation of the serfs.
In 1821, he was elected Volyn provincial leader of the nobility (marshal), but due to his young age, he was not confirmed by the governor. That same year, he was elected Kyiv provincial leader of the nobility, a position he held until June 1824.

Until 1868, the Olizar family was the owners of Korostyshiv and the surrounding forests. In the first half of the 19th century, with the support of Count Olizar, Korostyshiv's industry developed, a stone bridge was built, and a park was created on the left bank of the Teteriv River.
