are ecologically compatible and emphasize the use of natural materials and native plant species
where practical and available. Such stream bank stabilization/ erosion control practices should
only be undertaken upon approval of a Stormwater Pollution Prevention Plan (SWPPP or SWP3)
by the local reviewing agency and should follow the recommendations of the most recent version
of the Rainwater and Land Development Manual.
• Stream crossings
o Crossings of streams through the Riparian Setback by vehicles, storm sewers, sewer
and/or water lines, and public utility lines will be per the approval of local, county, and
state governing agencies and as a part of the regular subdivision process.
o Roadway crossings must be built in accordance with local regulations.
• Placement of stormwater retention or detention facilities may be considered within the
Riparian Setback if stormwater quality treatment is consistent with state standards (most
current version of the Ohio EPA general construction permit).
7.5 Uses Prohibited in the Riparian Setback
• Structures. There should be no structures of any kind except as permitted under these
regulations.
• Dredging or Dumping. There should be no drilling for petroleum or mineral products, mining
activity, filling or dredging of soil, spoils, or any material— natural or man-made—except as
permitted under these regulations.
• Drainage Alterations. Except as necessary to maintain the bed elevation or flow line of the
channel in the event of aggradation, there should be no manipulation or alteration of
wetlands, creeks, streams, surface or subsurface springs or other bodies of water, or any
activities on, or uses of, the property that may be detrimental to the aquatic or terrestrial
ecosystems of the property. The owner may conduct periodic inspections in collaboration
with local drainage authorities to measure the bed elevation or flow line of the water course.
Steps to restore original hydraulic capacity and original grade may be taken in situations
where local drainage authorizes have determined that lowered bed elevation or flow line and
aggradation impede subsurface drainage outlets or threaten to cause flood damage to
buildings or roads.
• Roads or Driveways. There should be no roads or driveways, except as permitted under
these regulations.
• Motorized Vehicles. There should be no use of motorized vehicles of any kind, except as
permitted under these regulations.
• Modification of Natural Vegetation. Modification of the natural vegetation should be limited
to conservation maintenance that the landowner deems necessary to control noxious weeds;
for plantings consistent with the policies of the local reviewing agency; for disturbances
approved by these agencies; and for the passive enjoyment, access and maintenance of
landscaping or lawns.
• Impervious Surfaces. There should be no parking lots or other human-made impervious
cover, except as permitted under these regulations.
7.5.1 Non-conforming Structures or Uses in the Riparian Setback
• Structures and uses within the Riparian Setback, existing at the time of approval of the
Riparian Setback plan, that are not permitted by the local reviewing agency may be
continued but should not be expanded except as set forth in this title, or approved by the
local reviewing agency.
