The $410 million bond package will go on the November ballot. Houston Mayor Annise Parker says the referendum does not require a tax increase and is the lowest bond package the city has requested in 30 years. The mayor says the referendum is essentially the city asking for permission to take out debt, although that does not mean the city will actually borrow the full amount authorized. Parker’s plan allocates the money to public safety, health and facilities, affordable housing, parks and libraries. Voters would cast their ballots in each of those categories. Parker says she knows the needs in Houston are more than $410 million, but that’s what the city coffers can handle. The city last issued a bond referendum in 2006.
