Rhode Island voters on Tuesday approved seven proposals that call for the financing of public projects with borrowed money. The most popular proposal to win approval in Tuesday's referendum calls for borrowing $74 million for environmental and recreation projects. It drew 78% of the vote. The borrowing package finances a wide range of spending from $33 million for upgrades at state beaches and parks to $6 million for dredging the Providence River. The $7 million for "municipal resiliency" initiatives to help cities and towns deal with rising seas and climate change was dear to Jeffrey R. Diehl, one of the many ballot proponents who was quite pleased with the mid-winter decisions of referendum voters.
