Assistance from the Mississippi Department of Health will be available for property owners who want to rebuild tornado-damaged homes on Sea Island Drive in the Eagle Lake community — provided they supply drawings to the agency.

Warren County officials said Monday letters will be mailed this week to those who owned structures either lost or heavily damaged. The letters will explain state law governing wastewater disposal systems that requires state approval on septic systems before a building permit is issued.

Assumptions are that temporary housing of some type will appear on 11 lots where homes were either flattened or heavily damaged by the powerful twister that swept across Mississippi’s midsection April 24.

Letters will be accompanied by a sheet of graph paper on which people must plot their property dimensions and show where they plan to place or build a new structure.

Once complete, the depiction must be taken to the Permit Office on the basement floor of the Warren County Courthouse.

Afterward, two MSDH field agents will travel to Eagle Lake on Tuesdays to inspect plans.

District 2 Supervisor William Banks said each completed drawing should be returned by noon on Mondays.

Supervisors adopted the Flood Damage Prevention Ordinance on Monday, a set of modifications to the county’s flood plain ordinances that compels landowners in the most flood-prone areas to lift new structures 18 inches above base flood elevation. The height also applies to the lowest floors on manufactured homes and RVs.

According to the added regulations, the mandatory raise kicks in if restoration costs on an unraised but damaged home equal more than 50 percent of its pre-tornado market value.

A FEMA disaster recovery center at Eagle Lake Volunteer Fire Department closed Friday.

A site next to Simmons Planting Company’s cotton gin is authorized to process storm debris through June 30.
