Saluda&squo;s concerns with the reclassification included some undersized lots that would be affected by the new ordinance. Odom said that the ordinance will only affect new development and already plotted lots will be grandfathered under current regulations.

Saluda Mayor Rodney Gibson said the city&squo;s existing zoning would essentially be unaffected because the city&squo;s lot size requirements are already sufficient.

The city currently has a 20,000 square foot minimum lot size requirement and the new watershed ordinance will increase that by about five or six percent, Saluda Planning Board Chairman Hal Greene said.

Other differences will be for storm water runoff requirements but will only affect new development.

Odom and Whitson said the county is currently working with Henderson County to get its support since much of the watershed affects Henderson County properties. Henderson County has previously expressed concern over the new watershed.

Polk County agreed earlier this year to purchase Lake Adger for a county water source for $1.6 million. The deal is expected to close in September or October.
