Ohio lawmakers passed H.B. 340, revising the state's petition ditch drainage laws, and county engineers and soil and water conservation districts begin following the revised law on March 18. The bill, sponsored by Rep. Bob Cupp, received unanimous approval in both the House and Senate.
Why it matters
The drainage laws were in serious need of updating after more than seven years of work by the Ohio Drainage Law Task Force, which the County Commissioners Association of Ohio convened to clarify ambiguous provisions and embrace new technologies. For Ohio landowners whose property sits in a petitioned drainage district, the changes affect repair costs, buffer strip requirements, and how assessments can be paid.
County engineer petitions now require a $1,500 bond plus $5 per parcel for any petition covering more than 200 parcels. The entire amount of sod or seeded strips is removed from taxable valuation of the property.
The players
Rep. Bob Cupp
Ohio state representative who sponsored H.B. 340 to revise the state's drainage laws.
County Commissioners Association of Ohio
Statewide association of county commissioners that convened the Ohio Drainage Law Task Force to update the drainage code.
The details
H.B. 340 updates the laws governing installation and maintenance of drainage works through the petition process, which lets landowners request improvements to shared ditches and drainage systems. Revised rules apply the same time frames, deadlines, notices, and hearing procedures to petitions filed with county engineers and soil and water conservation districts. The law also allows technology to substitute for an in-person view of a proposed drainage improvement site.
Timeline
Over seven years before the bill's passage, the Ohio Drainage Law Task Force began its updating process.
March 18: the revised drainage law takes effect and county engineers and soil and water conservation districts begin following it.
The Home Front
The revision updates an Ohio drainage code that governs shared ditch improvements for rural and agricultural property. Changes to repair thresholds and payment schedules shape how the cost of maintaining these systems is spread across the landowners who depend on them.
If your property is in or near a petitioned drainage district, check with your county engineer or soil and water conservation district about how the March 18 changes affect buffer strips and repair assessments. Ask whether a repair assessment can be spread across the new 10 semiannual installments before budgeting for any work.
The takeaway
Ohio landowners with drainage ditches on their property should plan for wider 10-foot sod or seeded strips and higher repair thresholds under the new law. Keep your county engineer and soil and water conservation district contact information on file before March 18.
