The largest bond in Richardson ISD history will go before residents in the May 1 election. Polls are open from 7 a.m. to 7 p.m.

The $750 million bond package includes two separate propositions. Proposition A totals $694 million and would cover infrastructure and safety projects, construction and renovation plans, and projects to support teachers and students. Proposition B totals $56 million and would cover updates to district technology devices.

If the bond is approved, RISD staff said the district's tax rate will not increase.

Voters may cast their ballots at any voting center in the county in which they live. For a list of polling places, click here for Dallas County or here for Collin County.
