However, he (as a now-elderly Senator of the Kingdom) submitted a plan to straighten the course of the Tiber, at a time in which the construction of new banks had just started after the flood of 1870. Said proposal also called for the elimination of the chokepoint near the Tiberine Island, which should've been joined with the left bank of the river.

The rationale behind such a plan was not only to further protect the city - a 'bendy' river being far more prone to floods - but also to eradicate malaria (the Tiber's then-grassy meadows proved an ideal habitat for mosquitoes during the summer droughts), boost tourism, as well as to provide the city with a more direct link to the new harbour at Ostia. Such a proposal was then duly ruled out and rejected for both political and budgetary reasons.
