Gorge Journal · Land & Access
Most Red River Gorge parcels reach the road across water. Before you place the culvert, the fill or the bridge that makes that crossing, you need a Kentucky stream construction permit: KRS 151.250 bars commencing construction of a bridge, fill, embankment or “other obstruction” in the floodplain or floodway of any stream until plans and specifications have been submitted to and approved in writing by the cabinet and a permit issued. This is a separate approval from the county or state entrance permit for the driveway itself, and it is the one that most often gets discovered after closing.
What does KRS 151.250 actually require?
Submitted plans, written approval from the cabinet, and an issued permit — before construction begins, not after.
The statute’s first subsection reads broadly on purpose. Notwithstanding any other provision of law, no person — and no city, county or other political subdivision, including levee, drainage and flood control districts — may commence the construction, reconstruction, relocation or improvement of any dam, embankment, levee, dike, bridge, fill, or other obstruction in the floodplain or floodway of any stream unless the plans and specifications have been submitted by the party responsible for the work and approved in writing by the cabinet, with a permit issued. The statute carves out work constructed by the Kentucky Transportation Cabinet, and it allows the cabinet to exempt by administrative regulation those obstructions not of a size or type requiring approval in the interest of safety or retention of water supply.
Subsection 2 is the one landowners underestimate. No person may commence the filling of, or place a building, barrier, or obstruction of any sort in, any area in the floodplain or floodway without the same submitted plans, approval and permit. A pad of fill to get a cabin out of the wet, a retaining wall, a shipping container used as a shed — the statute reaches all of it by category rather than by name. The current version has been effective since June 29, 2023.
Does this apply only inside a mapped FEMA flood zone?
The trigger in the regulation is the stream and its base floodplain, not whether a FEMA panel happens to show a shaded zone over your parcel.
401 KAR 4:060, Stream construction criteria, states its own applicability plainly: it applies to all construction across, along, or adjacent to a stream — that is, the base floodplain — or in the floodway of a stream for which a construction permit is required pursuant to KRS 151.250, 44 C.F.R. Part 60 and 44 C.F.R. 64.3, except for the construction of dams as defined in KRS 151.100.
The regulation defines “base floodplain” as the area along, adjacent to, and including a stream which is inundated by the base flood — the flood with a one percent chance of being equalled or exceeded in any given year, also called the 100-year flood. On a Gorge parcel, the practical consequence is that the absence of a FEMA designation is not an answer to the permit question. The stream is the question. Whether a specific crossing on a specific drainage needs a permit is a determination for the Kentucky Division of Water, and it is worth asking in writing before you buy, not after you have a bulldozer scheduled.
What is a floodway, and why is it the hard line?
The floodway is the channel plus the adjacent land needed to pass the base flood without raising the water surface more than one foot — and inside it, encroachment is prohibited unless an engineer certifies no impact.
Section 4 of the regulation is the strictest provision in the document. All encroachments — including fill, new construction, substantial improvements, and other development — are prohibited in the regulatory floodway unless certification with supporting technical data by a licensed engineer is provided demonstrating that the encroachment will have “no impact,” meaning no increase in flood levels during the base flood discharge. That is an engineering deliverable, not a form.
Section 4 then lists activities that are permitted within the floodway limits if they do not increase flood elevations. The list is instructive about what a floodway strip on a Gorge parcel is actually good for: open space uses with no appreciable flood damage potential, such as agriculture, silviculture, recreation, parking and storage yards; certain structures related to those open-space uses, such as aerial utility crossings, if designed and placed to offer no obstruction to flood flows; structures necessary for transportation or utility crossings under the stated conditions; dredging or removal of material where the spoil goes outside the floodway; and recreational vehicles for no more than 180 days if placed so they can be moved easily in case of imminent flooding.
A floodway strip is not unbuildable land. It is land where the only permitted improvements are the ones that let the water keep going.
Where the boundary runs is also defined rather than negotiated. Section 5 sets the regulatory floodway as the channel plus the adjacent land required to pass the base flood discharge without increasing the water surface elevation at any point more than one foot, using methods that consider equal conveyance losses on opposite sides of the stream. If a local government has adopted floodway boundaries by ordinance and FEMA has also mapped them, the regulation says the more stringent of the two applies. For a buyer comparing a county map against a FIRM panel, that resolves the conflict before it starts: the stricter line governs.
Who else has to be told about the permit application?
Anyone who may incur additional flood-related damage from your construction — and for projects with impacts beyond the immediate area, that means a newspaper notice you pay for.
Section 3 of the regulation builds public notice into the permit process. Each applicant must notify all parties who may incur additional flood-related damages as a result of the construction. For projects that may have flooding impacts beyond the local area of the construction, the applicant publishes a notice in the newspaper having the greatest circulation in the area. The notice has to carry the applicant’s name and address, the location, nature and extent of the proposed construction, and the address and telephone number of the Division of Water with a statement that comments and objections should be directed to the division.
| Notice requirement | What 401 KAR 4:060 Section 3(4) specifies |
|---|---|
| Where | The newspaper having greatest circulation in the area of the proposed construction |
| How often | Three consecutive days or printings |
| Weekly papers | The cabinet may reduce it to two consecutive printings on the applicant’s written request |
| Size | At least three column inches, and large enough to carry all required information |
In the Gorge counties, “the newspaper having greatest circulation” is frequently a weekly, which is why the two-printing reduction exists — and why it has to be requested in writing rather than assumed. The mechanics of publishing a legal notice in a Kentucky weekly are covered separately in notice by publication under KRS Chapter 424 on Kentucky land; the publication rhythm is the same even though the statute behind the notice is different.
The county already approved my driveway. Isn’t that the permit?
No. An entrance or encroachment permit governs where your driveway meets the road. A stream construction permit governs what you put in the water’s way.
These are different agencies answering different questions, and the exception written into KRS 151.250 is for construction by the Kentucky Transportation Cabinet — not for a private culvert that a road department signed off on. A Gorge driveway can clear the access review and still need a floodplain permit for the crossing structure a hundred feet in. Both approvals, and who issues which, are worth mapping before an offer; the access side is covered in the driveway permit for Red River Gorge land.
One more carve-out exists and it is narrower than it sounds. Subsection 3 says nothing in the section gives the cabinet jurisdiction over the construction, improvement, maintenance or operation of a drainage district, ditch or system established for agricultural purposes — but the same subsection then allows the cabinet to require approval before construction of structures, dams, embankments, levees, bridges, fill or other construction related to agricultural operations that impact the base flood of a stream. An agricultural purpose is not a blanket exemption.
What this looks like on a Gorge parcel
In my work on rural Kentucky land, the crossing is the item that most often separates a parcel’s asking price from its real cost to use, and it is almost never discussed in a listing. The habit worth building is to walk the access route on foot before writing an offer and to count the water crossings, then ask three questions in writing: what is already built at each crossing, what instrument or permit authorized it, and whether the parcel’s buildable area sits inside a mapped floodway. A parcel where the existing crossing is a few culverts laid in by a previous owner without a permit is not disqualified — but the next owner inherits the question, and the engineer’s no-impact certification is the expensive version of the answer.
Two related diligence items usually run on the same parcel: whether you need a survey to buy Red River Gorge land, and how a flood designation affects insurability, which is covered in Red River Gorge flood zones and property insurance.
None of this is legal or engineering advice, and I am not your attorney or your engineer. The Kentucky Division of Water decides what needs a permit, and a licensed engineer produces the certification the regulation requires. My job is to make sure the crossing is counted before earnest money moves.
Is a permit needed to replace a culvert that is already there?
KRS 151.250 reaches “construction, reconstruction, relocation, or improvement” of a bridge, fill, embankment or other obstruction in the floodplain or floodway. Reconstruction and improvement are both named, so the existence of a prior structure does not by itself answer the question. Ask the Division of Water about the specific work.
What is the difference between the floodplain and the floodway?
Under 401 KAR 4:060, the base floodplain is the area along, adjacent to and including the stream that the base flood inundates. The regulatory floodway is the narrower inner portion — the channel plus the adjacent land needed to pass the base flood discharge without raising the water surface more than one foot. Both are regulated; the floodway is where encroachment is prohibited absent a no-impact certification.
Can a seller tell me the parcel has no flood issue because it is not in a flood zone?
A seller can say it, but the regulation’s applicability language is written around streams and the base floodplain rather than around whether a FEMA panel shows a zone. Treat “not in a flood zone” as the start of the inquiry and confirm the crossing question with the Division of Water for the specific stream and the specific work you intend.
