What lakefront and shoreline work involves

Lakefront work covers the jobs at the water's edge on a lot: stabilizing an eroding bank, placing rock, building access to a dock, and the site work for a building close to the shore. Excavation equipment does much of it, but the rules are different from dry-land dirt work because the lake and its shore are public resources.

IDL regulates encroachments on navigable lakes so that property, navigation, fish and wildlife habitat, aquatic life, recreation, appearance and water quality are given due consideration. A company that has worked on lakefront lots knows the order of steps, but you should still read what IDL says and ask for it in writing.

This page covers the permit and the excavation questions. It does not decide whether a project will be allowed. IDL and the county make that decision, and a written answer from them is worth having before you agree to a price.

When people look into this

A bank or shoreline is eroding.
A dock or shore access is being built, repaired or changed.
Rock or other stabilization is needed along the water.
Site work is planned for a house close to the lake.
A lakefront lot is being bought or sold with an existing structure.
A water intake line is planned from the lake.

What the work usually looks like

Describe the project. Write down where it is, what changes and how much.
Contact IDL. Ask the Coeur d'Alene area office about the encroachment permit for your type of work.
Prepare the application. The packet includes the joint application form, drawings or maps, supporting documents and the fee.
Notice and comments. IDL notifies adjacent waterfront owners and, for some types of work, publishes notice in the local newspaper.
Record the permit. The approved permit is recorded with the county recorder.
Build, report and inspect. The work is done, a completion report is filed and IDL inspects.

How to prepare

Before work starts, it helps to settle these points:

Take photos of the shoreline and mark the work on a map.
Contact IDL and ask which encroachment application applies.
Gather drawings, maps and supporting documents IDL asks for.
Ask the county whether a floodplain authorization or other permit applies.
Ask any company who handles the application and pays the fee.
Find out who will give 811 notice for any digging on shore.
Get the scope, permits and price in writing.

What affects the cost

Excavation is commonly priced by the hour for operator and machine, or as a set price for a defined scope. At the water's edge, permits and controls add to the work itself.

Permit and application fees. IDL publishes a fee list, and drawings or plans may cost extra.
Waiting time. Notice to neighbors and, for some work, newspaper notice add time.
Access. Getting machines to a shoreline can need a temporary route.
Rock and materials. Stabilization material adds material and hauling cost.
Erosion control. Controls near water are heavier than on dry land.
Size and slope. Longer or steeper banks need more work.
Other approvals. A submerged land lease or easement, or a floodplain authorization, can be required.

Buying or selling a lakefront lot

IDL has a separate process when lakefront property with an existing encroachment is bought or sold. Its page says a request for assignment form and a fee are required when buying or selling lakefront property with an existing encroachment. If you are buying a lot with a dock or shoreline stabilization, ask the seller for the permit and check with IDL that it is current.

It also helps to ask before you plan new work. A structure that is already permitted may be repaired differently from one that is not, and IDL can say which rules apply to your situation.

Local rules and sources

State permit. Before building an encroachment on a navigable lake, such as a dock, marina or shoreline stabilization, an encroachment permit from the Idaho Department of Lands (IDL) is required under the Lake Protection Act (Idaho Code Title 58, Chapter 13) and IDAPA 20.03.04. IDL says the rules were approved by the 2026 Idaho Legislature and took effect July 1, 2026.

Process. IDL's process includes the applicant submitting a packet to the area office, IDL notifying adjacent waterfront owners (and, for most other encroachments, publishing notice in the local newspaper), IDL issuing a permit, the permittee recording it with the county recorder, constructing, filing a work completion report and IDL inspecting.

Other authorizations. IDL says a submerged land lease or easement may be required as a condition of a permit, a water right permit from the Idaho Department of Water Resources is required to draw water from surface water, and a floodplain authorization may be required from the county. Encroachments built before 1975 and not modified since may be permitted without a fee with documentation.

Utility locates. Under Idaho Code 55-2205, the excavator marks the dig area in white paint and gives notice two to ten business days before digging. Once utilities mark their lines, the excavator is responsible for keeping the markings visible, and they stay valid for no more than four consecutive weeks. If digging hasn't started within three weeks of the notice, notice must be given again. Wait until every utility on the ticket has responded before you dig.

Registration. Idaho requires contractors to register with the Idaho Contractors Board at the Division of Occupational and Professional Licenses (DOPL). Idaho law counts excavating as construction (Idaho Code 54-5203). Some work is exempt, such as a single small project priced under $2,000 that is not part of a larger job (54-5205). Check the company on DOPL's public search before you agree to anything.

Common questions

Do I need a permit for shoreline stabilization on a lake in Idaho?

IDL says an encroachment permit is required before building an encroachment on a navigable lake, with a dock, marina and shoreline stabilization given as examples. The requirement comes from the Lake Protection Act and IDAPA 20.03.04. Contact the Idaho Department of Lands office for your area before any work starts.

What does the IDL permit process include?

An applicant submits a packet to the area office, IDL looks it over and notifies adjacent waterfront owners and sometimes the public, issues a permit if approved, and the permittee records it with the county recorder, builds, files a completion report and gets an inspection. Ask IDL which steps apply to your project.

Is anything else required besides the IDL permit?

IDL says a submerged land lease or easement may be required as a condition of the permit, a water right permit from the Idaho Department of Water Resources is needed to draw surface water, and a floodplain authorization may be required from the county. Ask each agency early, and get answers in writing.

What if the structure was built before 1975?

IDL says encroachments built before 1975 and not modified since may be permitted without a fee if you provide substantive documentation of the age and that it has not been modified, such as dated aerial photographs or tax deeds. Ask IDL what it accepts for your structure.

Who handles the permit paperwork?

Settle it in writing before work starts: who applies, who pays the fee, who provides drawings and who follows the permit conditions. Excavation is commonly priced by the hour for operator and machine, or as a set price for a defined scope, so confirm whether permits are in the scope or separate.
