MERCER, Wis. -- The Mercer School District again will ask voters for approval to raise more tax money than state revenue limits allow.

The November ballot will ask for approval for an additional $350,000 per year for five years beginning in 2009-10.

The Mercer School Board on Monday approved a resolution to put the referendum on the general election ballot, superintendent Jeff Ehrhardt said Tuesday.

Voters earlier approved additional revenue of $250,000 per year for three years. The final year of that referendum is 2008-09.

Ehrhardt said the dollar figure of the November referendum was "based on revenue projections over the next five years."

The district is hobbled by increasing property values and declining enrollment. Both are factors in how much tax revenue the district can collect and how much state aid it receives.

The $350,000 per year referendum would cost the owner of a property valued at $100,000 an additional $22 per year above the current referendum's extra $55, according to a news release issued Thursday by the Mercer School Referendum Task Force.

The 2007-08 Mercer school mill rate is $4.69 per $1,000 of property value -- or $469 for that $100,000 property.

The news release says the district has three options:

--Approve the new referendum to keep the school open.

--Close the school and dissolve the district.

--Consolidate with another district.

The task force contends that dissolving the district or consolidating -- most likely with Hurley -- would cost Mercer taxpayers more money in school taxes than the new referendum.

"Voting against the referendum is a vote for a large tax increase," the news release says. "Supporting the referendum is a vote for a modest tax increase."
