Under his influence, Utrecht became the most important city in the northern Netherlands and he expanded the power of the local diocese so that it could maintain itself between the surrounding counties.
In exchange, Otto granted Balderic the right of coinage in Utrecht, as well as the trade settlement Muiden including the important toll.
Furthermore, he acquired hunting rights in Drenthe, and several possessions in the Gau (country subdivision) Lek and IJssel.
In 1481, an important part of his remains from Utrecht were moved to the St. Plechelmusbasilica in Oldenzaal and buried there, probably as a tribute to the founder of its chapter.
The tombstone of that year is preserved and built into the west wall of the south aisle of the St. Plechelmusbasiliek.
