The Jefferson County Board of Commissioners said Friday they will study the possible annexation of several county areas into the city of Madison.

The plan, created by Mayor Damon Welch and his staff, would annex four areas into city limits: State Road 56 west to Clifty Drive; State Road 62 from the intersection at U.S. 421 up to Olive Branch Road and U.S. 421 north to Dawson Smith Road; Dawson Smith Road to State Road 7; and extending the eastern border of downtown to Fulton Street.

Those areas would include all properties belonging to Indiana-Kentucky Electric Corp, King's Daughters' Hospital, Madison Precision Products, Century Tube, Meadows subdivision and Indian Cave subdivision.

Commissioners' President Mark Cash said he feels annexation would "negatively impact" the county's tax revenue. He pushed the idea of the study in order to find the exact financial impact on county government and county residents.

"We have to know what those numbers are going to be," Cash said.

The commissioners plan to hire Indianapolis firm H.J. Umbaugh and Associates to review the proposed annexation and identify the impact on tax caps and the county's CEDIT - County Economic Development Income Tax - fund.

The fee is $5,750 but is contingent on County Council approval.

Commissioners Tom Pietrykowski agreed with Cash.

"I'm not big on studies but this one, I think, is necessary," he said.

County Attorney Wil Goering said the information from H.J. Umbaugh will be distributed to the county and city, as well as the residents that would be affected by the proposed changes.

The mayor has not introduced any annexation plan to the City Council and has said the project is still in its early study phase.

According to a report prepared for the city by the Reedy Financial Group, annexing all four properties would only add between $40,000 and $80,000 in additional revenues. The total population increase would be about 365 people.

Also at the meeting, Colby King of FPBH, reported that the Audubon Park housing division drainage overhaul project has reached substantial completion and will be under budget.

The project, handled by Sedam Contracting, is being funded by a $500,000 federal grant. Crews met the substantial completion April 26, King said.

In addition, the project came in about $8,000 under budget. The commissioners decided to use the remaining grant money - and a portion of its paving budget - to mill and pave two sections of Quail Drive.

The additional paving will cost about $19,000, which the county will cover. The commissioners said they wanted to conduct the paving while crews were already working on the area.

In other business:

• The Jefferson County Election Board was given approval by the commissioners to store their voting machines inside the old jail. The plan is to store the machines inside an evidence cage that will then be placed inside the old jail.

Sheriff John Wallace said the area is temperature regulated and does not have issues with water or dampness.

The election board will now begin seeking quotes for the work cage.

• Health Administrator Tammy Monroe reported that the handicap doors and automatic openers at the front of the health department building are out of order and need to be replaced. Monroe presented one quote that gave an estimate of more than $6,000 for the work. The commissioners asked Monroe to seek out a few more quotes before they make a decision.

• The commissioners approved an annual contract with SRI, the company that handles the county's tax sales. The fee was reduced from $75 a parcel to $70 a parcel this year.
