Often, yes—but being close to water does not by itself answer whether you may build. Approval depends on the exact footprint and construction methods, whether work would discharge dredged or fill material into federally jurisdictional waters, the site’s flood hazard, and state, tribal, and local rules. A stream setback that applies in one jurisdiction may not exist—or may be much larger—in another.
What “near water” actually means legally
Three different questions are commonly mixed together:
As an Amazon Associate I earn from qualifying purchases.
- Wetland question: Do wetland characteristics occur on the parcel, and where are their boundaries?
- Federal jurisdiction question: Are the stream, wetland, or other aquatic resources regulated under Clean Water Act Section 404?
- Floodplain question: Is the proposed development in a mapped flood hazard area governed by a local floodplain ordinance?
A property can have a wet area that is not federally jurisdictional, or be outside a mapped floodplain while still needing wetland, stormwater, septic, or local land-use approvals. Conversely, a project can avoid wetlands yet still require a floodplain-development permit. Treat these as separate reviews rather than looking for one universal “buildable distance.”

Section 404: when fill or excavation triggers federal review
Section 404 generally requires authorization before a person discharges dredged or fill material into waters of the United States, including federally jurisdictional wetlands. “Fill” can include soil, rock, sand, gravel, concrete, and other material placed to raise land, create a pad, build a road, install a crossing, or redirect water. A house may be outside a wetland while its driveway, utility trench, retaining wall, grading, or temporary access crosses one.
Ordinary proximity is not the trigger. A building 20 feet from a stream is not automatically prohibited, and a building 200 feet away is not automatically cleared. The relevant questions are whether regulated waters are present, whether the project discharges dredged or fill material into them, and whether another law or local ordinance imposes a buffer or other condition.
General and individual permits
EPA describes a review sequence that prioritizes avoidance of impacts where practicable, then minimization of unavoidable impacts, and finally compensation for remaining impacts. A general permit may cover a defined category of work with minimal adverse effects when every applicable condition is met. Projects with potentially significant impacts generally require an individual permit and a project-specific review.

One-click scans. No signup required.
General-permit eligibility is not a blanket approval. Conditions can address the amount and type of fill, timing, erosion and sediment controls, protected species, cultural resources, notification, and mitigation. Exceeding a threshold or failing a condition can move a project into individual-permit review. Do not place fill while assuming that a permit can be obtained later.
Activity-specific exemptions
Section 404(f) contains exemptions for certain established farming, ranching, silviculture, and specifically listed maintenance or construction activities. The exemption depends on the exact activity, its ongoing status, and compliance with statutory conditions. It is not a general exemption for a new homesite, subdivision, commercial building, or access road.
EPA explains that a discharge associated with converting a wetland to upland is generally not exempt. A landowner who drains, fills, or grades a wetland to make a building lot should obtain an agency determination before relying on any exemption. Ask the responsible Corps district or an assumed state or tribal program to confirm the exemption in writing.

Wetland boundaries and federal jurisdiction are different findings
A wetland delineation maps areas that meet technical wetland criteria. A jurisdictional determination (JD) addresses whether aquatic resources are regulated under Section 404 and identifies the geographic limits of that jurisdiction. One does not automatically substitute for the other.
How wetlands are identified
EPA states, “Wetlands must have three specific criteria in order to be classified as a wetland: hydric soils, hydrophytic vegetation, and hydrology.” The Corps of Engineers Wetlands Delineation Manual (1987) and regional supplements are used for Section 404 work. A qualified environmental consultant typically examines soil profiles, plant communities, and evidence of current or seasonal water conditions, then marks the boundary with flags or survey points.
Desktop maps, aerial imagery, soil maps, and national wetland inventories are useful screening tools, but they can miss small, altered, forested, or seasonal wetlands. A field delineation is more defensible for design and permitting. It should cover the entire disturbance area, including driveways, septic fields, utility routes, staging areas, drainage outlets, and temporary access.
Approved versus preliminary jurisdictional determinations
An approved JD is the Corps’ definitive determination that jurisdictional aquatic resources are—or are not—present in the review area and where their limits lie. The Pittsburgh District page cited for this process says approved determinations are valid for five years; confirm the current validity period and service conditions with the district serving your property.
A preliminary JD is advisory. It treats aquatic resources in the review area as jurisdictional for purposes of moving forward without making a definitive final call. That can help an applicant proceed with a conservative permit analysis, but it does not provide the same certainty as an approved JD.

Pick the symptom - the matching free tool is one click away.
A JD is not a prerequisite to submitting a permit application. An owner may request one when jurisdiction is uncertain, or proceed directly to an application if the project and agency process make that more efficient.

Floodplain rules create a separate permit pathway
Flood regulation is based on flood hazard and local ordinance, not only on wetlands. In a community participating in the National Flood Insurance Program (NFIP), development in a designated Special Flood Hazard Area generally requires a floodplain-development permit before construction or other development begins. “Development” can include grading, excavation, filling, placement of structures, storage, roads, and substantial improvements, depending on the community’s ordinance.
Start with the effective FEMA map
Use FEMA’s Map Service Center and National Flood Hazard Layer to locate the effective map for the parcel. Record the panel number, effective date, flood zone, and whether the site lies in a regulatory floodway. Then take that information to the local floodplain administrator. FEMA’s review checklist directs officials to use the effective map and to consider whether a project is in a regulatory floodway; other available data may be relevant where map coverage is limited.
A map is a starting point, not a construction approval. Boundaries can be approximate, elevation data can be incomplete, and local ordinances can regulate areas beyond the mapped Special Flood Hazard Area. The administrator may request a site survey, base-flood-elevation data, hydraulic analysis, or other supporting information.
Elevation, floodproofing, and freeboard
Local ordinances can require the lowest floor of a building to be elevated above the applicable base flood elevation, or require engineered floodproofing for eligible nonresidential structures. Communities may adopt freeboard, requiring additional elevation above the NFIP minimum. Confirm the current standard, the required certificate or engineering, and whether the project is new construction, substantial improvement, or repair of a substantially damaged building.
The community must review necessary federal, state, and local permits before issuing its floodplain approval. A floodplain permit does not replace a Section 404 authorization, wetland approval, stormwater permit, septic approval, building permit, or other required review.
LOMR and CLOMR are not building permits
A Letter of Map Revision (LOMR) officially revises an NFIP map. A Conditional Letter of Map Revision (CLOMR) comments on whether a proposed project would meet minimum NFIP standards if built as proposed. Neither document substitutes for permits required by the community or other agencies. Do not treat a favorable map-change decision as permission to start earthwork.

Draw the house or commercial structure, grading limits, driveway, culverts or bridges, septic and reserve areas, wells, utilities, drainage outlets, retaining walls, stockpiles, and temporary work areas. Note excavation as well as fill.
- Identify every aquatic resource. Review available maps and commission a field wetland delineation when water, hydric soils, wetland vegetation, or uncertain boundaries are present. Have the survey tied to the property boundary and proposed design so the agency can measure impacts.
- Choose a jurisdiction strategy. Ask the Corps district whether an approved or preliminary JD is appropriate, or whether the project can proceed directly to a permit application. If the state or a tribal authority administers an assumed Section 404 program for the relevant waters, contact that program as well.
- Screen the design for avoidance. Shift the building pad, driveway, utilities, and staging area away from aquatic resources before seeking authorization. A smaller, upland footprint can avoid a discharge and reduce mitigation, engineering, and review risk.
- Determine the Section 404 path. Confirm whether a general permit category fits and whether its conditions, thresholds, and notification requirements can be met. If impacts may be significant, plan for an individual permit and the associated alternatives and mitigation analysis.
- Check FEMA and local flood rules. Obtain the effective map, identify the zone and floodway status, and meet with the local floodplain administrator. Ask for base flood elevation, freeboard, elevation or floodproofing standards, and any local buffer or no-rise requirements.
- Get written confirmation before ground disturbance. Make a list of permits and approvals required before clearing, grading, filling, trenching, or construction. Keep delineations, JDs, map panels, surveys, agency correspondence, and permit conditions with the construction documents.
Compare designs before choosing a site plan
When more than one layout is possible, compare the options using the same criteria. The least expensive earthwork plan can become the most expensive after mitigation, redesign, elevation, or enforcement risk is added.
| Design or location | Aquatic-resource impact | Likely Section 404 question | Floodplain exposure | Trade-offs to examine |
|---|---|---|---|---|
| Upland footprint set back from mapped resources | Potentially avoids direct wetland or stream disturbance | Confirm that grading, access, utilities, and drainage also remain outside jurisdictional waters | May still be in a Special Flood Hazard Area | Often reduces permitting and mitigation, but may require a longer driveway or more difficult utilities |
| Crossing or driveway through a wet area | Direct discharge or excavation may occur | Determine whether a general permit category and conditions fit; otherwise evaluate an individual permit | Culvert, bridge, and floodway standards may apply | Shorter access can create higher design, mitigation, and maintenance obligations |
| Fill to create a building pad | Can convert wetland to upland and permanently remove functions | Wetland-conversion discharge is generally not exempt; avoidance and alternatives analysis are important | Fill can alter flood storage and trigger floodway or no-rise review | May require substantial fill, elevation engineering, compensatory mitigation, and longer review |
| Redevelopment or addition to an existing structure | Existing disturbance does not automatically authorize new impacts | Determine whether new fill, expansion, or maintenance qualifies for any applicable provision | Substantial-improvement and substantial-damage rules may apply | Can reuse infrastructure but may face strict elevation, floodproofing, and documentation requirements |
Permit fees, review times, mitigation amounts, and engineering costs are not established nationally; they depend on the agency, location, project size, and chosen design.
State, tribal, and local rules may be stricter
Section 404 is only one layer of approval. Some states and tribes have assumed the Section 404 program for certain waters. EPA says the Corps retains jurisdiction over tidal waters and adjacent wetlands, waters used for interstate or foreign commerce, and adjacent wetlands. The precise division depends on the water, the program assumption, and current agency rules.
Separate requirements may include state wetland or stream permits, isolated-wetland protections, shoreland or riparian buffers, stormwater construction permits, erosion and sediment controls, septic and well setbacks, critical-area rules, endangered-species review, historic-resource review, subdivision approval, zoning, and building permits. Local governments can impose setbacks or conservation buffers that are unrelated to federal jurisdiction. Because no state, tribe, parcel, or project was specified here, no universal setback distance can be stated.

Common mistakes and how to avoid them
“The wetland map shows nothing, so I am clear.”
Screening maps are not a field delineation and may not show small or seasonal wetlands. Have the disturbance area evaluated when site conditions suggest wetland indicators.

“The stream is on my property, so I can place fill in it.”
Land ownership does not eliminate federal, state, tribal, or local regulation. Confirm jurisdiction and authorization before placing any material in the channel, bank, floodplain, or adjacent wetland.
“A farm exemption covers my new homesite.”
Exemptions are activity-specific and often require an established operation and compliance with conditions. A new conversion of wetland to upland is generally not exempt.
“A FEMA zone tells me exactly where I can build.”
Maps identify flood hazards; they do not approve a design. Ask the local administrator about the effective panel, floodway, base flood elevation, freeboard, and local ordinance.

Questions to ask the agencies and your consultant
- What is the exact disturbance footprint, including temporary impacts?
- Which aquatic resources were delineated, and which are considered jurisdictional?
- Should the owner request an approved JD, a preliminary JD, or proceed with a permit application?
- Does the project fit a current general permit, and what conditions or thresholds apply?
- Would any claimed exemption cover this precise activity and location?
- What is the effective FEMA map panel, flood zone, floodway status, and base flood elevation?
- What elevation, floodproofing, freeboard, no-rise, drainage, or compensatory-storage standards apply locally?
- Which state, tribal, local, stormwater, septic, zoning, and building approvals are needed before each phase of work?
- What documents must the contractor keep on site, and who has authority to stop work if boundaries or conditions change?
EPA reports on one of its Section 404 pages that “Overall, more than 95% of all projects receive Section 404 authorization.” The page does not identify a publication year or underlying dataset in the cited material, and the figure cannot predict approval of a particular proposal. Site-specific facts, impact avoidance, permit category, and compliance with conditions control the outcome.
Bottom line for a property owner
You may be able to build near a stream, wetland, or floodplain, but there is no reliable nationwide answer expressed as a single setback number. Map and survey the full project, separate wetland delineation from federal jurisdiction, determine whether fill or excavation requires Section 404 authorization, and obtain the local floodplain decision before construction. Move the design onto upland and outside the floodway where practicable; then confirm every remaining federal, state, tribal, and local requirement in writing before clearing, grading, filling, or building.
