(1) Prepare and make available to the public design standards of rainfall intensity and frequency for urban land, design standards of storm water runoff for urban land, or both.

In preparing this information, the county surveyor shall consider recommendations of state and local planning agencies, plan commissions, zoning boards, and similar bodies.(6) Include in the county surveyor's report to the board on the construction or reconstruction of an urban drain the county surveyor's recommended designation of each parcel of affected land in the watershed of the urban drain as either urban land or rural land.Pre-Local Government Recodification Citation: 19-4-10-2.
