Nassau County Executive Edward Mangano has submitted an updated four-year financial plan to the county's financial control board, outlining how the county plans to pay for at least $130 million in wage increases for union employees that were approved in May.

The plan, submitted to the Nassau Interim Finance Authority late Tuesday, was mandated by the fiscal control board when it allowed Mangano to lift the county's three-year wage freeze and enter into new contracts with county labor unions.

In the 76-page report, the Mangano administration said it expects to generate $14.2 million this year and $30 million in 2015 from 56 new speed cameras in school zones. Motorists who exceed the posted speed limit by more than 10 miles per hour will be subject to $50 fines.

The report covers the period from 2014-17.

The administration also estimates the county will generate $15 million from service fee increases approved by the Nassau County Legislature last month.

Mangano spokesman Brian Nevin said "the plan includes the measures needed to keep County property taxes frozen for the fifth consecutive year."

NIFA chairman Jon Kaiman could not be reached for comment late Thursday.

The NIFA board may consider the report later this month when it meets to vote on a proposed new contract with the Nassau corrections officers union, and to review a proposed sewer-privatization deal unveiled by Mangano last month. A meeting date has not been scheduled.
