Search Colorado Wetland Permits, Jurisdiction & Application Records
A Colorado wetland permit search can involve more than one database. Depending on the water feature and proposed work, the controlling record may be a Colorado dredge-and-fill authorization, a U.S. Army Corps of Engineers Section 404 permit, a federal jurisdictional determination, or a separate county or municipal approval.
This guide shows where to look, how to tell state and federal jurisdiction apart, and which records matter when you are researching a property, development site, road crossing, utility project, stream project, or wetland impact.
Where Should You Start a Colorado Wetland Permit Search?
Start with the water feature, not the building permit
If a project may fill, excavate, grade, place material in, cross, drain, or otherwise disturb a wetland or other aquatic resource, first determine whether the affected area may be regulated as federal waters, Colorado state waters, or both.
For federal records, use the U.S. Army Corps of Engineers Regulatory Program and its public permit and jurisdiction databases. For state-only waters, use the Colorado Department of Public Health and Environment Water Quality Control Division’s dredge-and-fill program.
Three Record Systems May Matter for the Same Colorado Project
Colorado WQCD
Use the Colorado dredge-and-fill program for state-water authorizations, general authorization coverage and individual authorization information.
U.S. Army Corps
Use USACE records for Clean Water Act Section 404 actions, approved jurisdictional determinations, pending individual permits and issued individual permits.
County or city
Check the local authority for floodplain development, grading, stormwater, land-use, road-crossing, erosion-control or building approvals connected with the same project.
Local approvals do not replace state or federal wetland authorization.
| What you need | Best starting point | Useful search detail |
|---|---|---|
| Federal wetland jurisdiction decision | USACE Approved Jurisdictional Determination records | Project name, location, Corps file number, district or year |
| Section 404 permit or application | USACE Regulatory Public Data / Regulatory Request System | Applicant, project, coordinates, county or ORM number |
| Colorado state-water authorization | CDPHE Water Quality Control Division | Project name, applicant, location and authorization type |
| Complete state application file | WQCD records request when not available online | Exact project, date range, applicant and location |
| Local development approval | County or municipal planning/public works department | Street address, parcel, subdivision, case or permit number |
Why Wetland Jurisdiction Matters Before You Search Permit Records
Wetland regulation in Colorado now has an important state-federal split. Federal Clean Water Act Section 404 applies to discharges of dredged or fill material into waters that fall within federal jurisdiction as “waters of the United States.” The U.S. Army Corps of Engineers administers the Section 404 permitting process.
Colorado separately regulates qualifying discharges into state waters under its dredge-and-fill program. The state program was created after the U.S. Supreme Court’s 2023 Sackett v. EPA decision narrowed federal wetland jurisdiction, leaving some Colorado aquatic resources outside the federal Section 404 program.
Do not assume “not federal” means “no permit”
A wetland that is outside federal Section 404 jurisdiction may still be covered as a Colorado state water. That is why an old federal “non-jurisdictional” conclusion should not automatically be treated as permission to fill or disturb the area under current Colorado law.
Federal jurisdiction is still evolving
As of October 21, 2026, EPA and the Department of the Army are still working on an updated federal definition of “waters of the United States.” A supplemental proposed rule was published September 9, 2026, and its comment period closed October 9, 2026. A proposal does not itself replace the currently applicable regulatory framework.
For a site-specific federal determination, rely on the Corps rather than attempting to decide jurisdiction from a wetland map alone.
What a jurisdictional determination can tell you
An Approved Jurisdictional Determination, commonly called an AJD, documents the Corps’ determination about the presence or absence of federally regulated waters on a specific review area. USACE states that AJDs are generally valid for five years, subject to the governing legal and factual circumstances.
A jurisdictional determination is useful when the status of wetlands, streams or other aquatic features is uncertain, but USACE also explains that a JD is not required in every case before a permit application can be filed.
How to Find Colorado Dredge-and-Fill Authorization Records
The Colorado Department of Public Health and Environment’s Water Quality Control Division administers the state’s dredge-and-fill authorization program under Regulation 87. This is the first place to check when a wetland or other state water may not be covered by federal Section 404 jurisdiction.
For current program documents
Use the official CDPHE dredge-and-fill page to review current general authorizations, conditions, application materials, implementation guidance and program updates.
For a specific application file
If the exact authorization, application, notice, correspondence or project file is not available through a public-facing list, request the record from the Water Quality Control Division records center.
Information to include in a records request
A narrowly described request is usually more useful than asking for “all wetland records in the county.” For due diligence, identify the project or parcel as precisely as possible and request the application, authorization, supporting maps, agency correspondence, public notice material and final decision if those records exist.
Colorado Environmental Online Services
CDPHE also operates Colorado Environmental Online Services, or CEOS, as an environmental permitting and submittal platform. CEOS can be useful for environmental permit administration, but do not assume every dredge-and-fill file can be located through a single permit-number search. Use the specific dredge-and-fill program instructions for the current submission or records route.
How to Search USACE Section 404 Permits and Jurisdictional Determinations
The U.S. Army Corps of Engineers now provides a national public data interface for regulatory actions. It can be used to locate approved jurisdictional determinations and several categories of permit activity.
Use this when you want to know whether the Corps has issued an AJD for a project area.
Search USACE AJDsUse the broader map and table interface to review available regulatory actions and filter records.
Open Regulatory Public DataUse RRS to start a new jurisdiction request, permit-related request or pre-application process.
Open USACE RRSUse the USACE jurisdiction section to understand AJDs, preliminary JDs and related request forms.
Review jurisdiction guidanceSearch with a Corps file number when possible
USACE regulatory records frequently use an agency file or ORM number rather than a county building-permit number. If an environmental report, engineering plan, public notice or prior correspondence contains a Corps number, search that identifier first.
For example, historic Colorado Corps records can carry prefixes associated with the responsible district. A file number is usually more precise than an applicant name because company names and project names can change.
Colorado is divided between two USACE regulatory districts
USACE regulatory responsibility in Colorado is divided between the Omaha District and Albuquerque District. The Omaha District’s Denver Regulatory Office handles the northeastern portion of the state, including the Denver-area regulatory region. The Albuquerque District administers regulatory work in the remaining Colorado areas, including western and southern offices.
| Office route | General coverage | When to use it |
|---|---|---|
| Omaha District — Denver Regulatory Office | Northeastern Colorado / Denver-region regulatory area | Questions about Section 404 and jurisdiction in the Omaha District portion of Colorado |
| Albuquerque District — Colorado offices | Other Colorado regulatory areas, including western and southern portions | Projects outside the Omaha District’s Colorado regulatory area |
Check current USACE Colorado regulatory office contacts and boundary information before sending a site-specific request.
How to Search Colorado Wetland Permit Records for a Property or Project
- Identify the exact project location. Start with the street address, parcel, legal description or coordinates. Wetland and Corps records may be mapped by project area rather than by a normal postal address.
- Find any existing environmental reference numbers. Review site plans, environmental assessments, wetland delineation reports, development files and agency correspondence for a Corps ORM number, Colorado authorization number or application identifier.
- Search the USACE jurisdiction database. Check approved jurisdictional determinations by location, district, year and project information. Open matching records and compare the review area with the property you are researching.
- Search federal permit activity. Use USACE Regulatory Public Data for issued or pending regulatory actions. Do not treat an AJD as proof that a Section 404 permit was issued.
- Check Colorado’s dredge-and-fill program. If state waters may be involved, review the CDPHE Regulation 87 program and current authorizations. Request the WQCD file when a public-facing record does not provide the documents you need.
- Check local development records separately. Search the county or municipality for grading, floodplain, stormwater, land-use, right-of-way and building records connected to the same work.
- Compare the permit area with the actual disturbance. A permit for one crossing, wetland cell or project phase does not automatically cover later work elsewhere on the property.
- Verify current status with the responsible agency. Confirm whether coverage is active, expired, completed, superseded, modified or still under review before relying on the record for construction or due diligence.
Colorado General, Individual and Isolated-Water Authorizations
Colorado’s Regulation 87 framework is not a single universal “wetland permit.” The correct route depends on the type and magnitude of the activity, the affected water and whether a general authorization applies.
| Authorization path | Typical use | Record to look for |
|---|---|---|
| General Authorization | Categories of similar activities with minimal individual and cumulative impacts | Coverage notification, notice of authorization, conditions or related application material |
| Individual Authorization | Projects that do not qualify for an applicable general authorization or have greater project-specific impacts | Application, public notice material, agency review, mitigation documents and final authorization |
| Isolated State Waters General Authorization | Qualifying work in isolated wetlands, isolated ponds or impoundments and isolated ordinary-high-water-mark reaches | Evidence that the activity meets the authorization’s eligibility, limits and conditions |
Special thresholds for isolated state waters
Colorado law provides a statewide general authorization route for qualifying isolated state waters, but it does not cover every isolated wetland project. The authorization cannot cover a project when the entire project’s unavoidable adverse impacts exceed one-tenth of an acre of wetlands or three-hundredths of an acre of streambed.
Colorado law also identifies fens, peatlands and kettle ponds as isolated state waters of significance that are not covered by that isolated-waters general authorization route.
Compensatory mitigation
The Colorado statute requires compensatory mitigation in individual authorizations and in applicable general authorizations when unavoidable adverse impacts exceed the statutory thresholds for wetlands or streams. Mitigation requirements are project-specific and should be read from the actual authorization rather than inferred from acreage alone.
Individual authorization timing
Colorado law directs the division to act on an individual authorization application within two years after receiving a complete application, subject to specified extensions. That is a statutory outside framework, not a promise that every application will take two years or that every case will be completed quickly.
A Wetland Authorization Does Not Replace County or Municipal Permits
A project can have valid wetland authorization and still require other approvals. This is common when wetlands overlap with floodplains, drainage corridors, road crossings, utility work or land-development areas.
Search the local planning, public works, engineering, floodplain or building department using the project address and parcel number. For a large development, also search by subdivision name, development case number and developer name.
Do not assume the county permit file will contain the full federal or state wetland record. Local files may reference a Corps permit or environmental report without reproducing every federal or state document.
What to Check Once You Find a Wetland Permit Record
Finding a matching project name is only the first step. Open the documents and verify that the authorization actually covers the location and work you are researching.
| Field | What to verify | Why it matters |
|---|---|---|
| Applicant / permittee | Correct owner, entity or project sponsor | Similar project names can belong to different sites |
| Review area | Maps, coordinates and boundaries | A determination may cover only part of a parcel |
| Aquatic resource | Wetland, stream, pond or other affected feature | Different resources can have different jurisdiction or conditions |
| Authorized activity | Crossing, fill, excavation, restoration, utility, road or other work | Authorization is tied to a defined scope |
| Impact acreage / length | Permanent and temporary impacts | Impact limits can affect authorization eligibility and mitigation |
| Conditions | Mitigation, reporting, construction windows or special conditions | Approval can be conditional rather than unrestricted |
| Status / date | Pending, issued, expired, superseded or completed | Historic approval may not authorize current work |
What If You Cannot Find the Colorado Wetland Record?
No result appears for the property address
Federal and state environmental records often are not indexed like building permits. Search the project name, developer, nearby road, waterbody, coordinates or agency file number. Use the county assessor or GIS system to confirm the parcel and coordinates first.
You found a wetland delineation but no permit
A delineation identifies and maps aquatic resources; it is not automatically a jurisdictional determination or authorization. Check whether the report lists a USACE project number, agency consultation, state authorization, proposed impacts or a statement that no discharge was planned.
You found an AJD but no Section 404 permit
That can be normal. A JD addresses jurisdiction, while a permit authorizes regulated activity. The project may not have required a permit, may not have moved forward, may have been redesigned, or may have proceeded through a separate general authorization.
You found an old “non-jurisdictional” federal record
Check the date, the legal framework applied and whether Colorado state authorization requirements now affect the water. The state’s current program should be reviewed separately before treating an old federal determination as evidence that no authorization is required today.
The project crosses both wetland and floodplain areas
Search both environmental and local floodplain records. A Corps or Colorado authorization does not substitute for a local floodplain-development decision, and local floodplain approval does not substitute for wetland authorization.
The project is pending
Look for public notices, application status, agency correspondence and requests for additional information. Do not treat a submitted application as an issued authorization.
Wetland Permit Search Checklist for Buyers, Owners and Developers
Wetland records can materially affect where a project can be built, graded or expanded. Before relying on a property for development, compare the records with current site conditions and the proposed construction footprint.
For property transactions
A “no permit found” search result is not conclusive proof that a property has no regulated wetlands or that past work was lawful. Online databases can be incomplete, older records may be archived, and some activities may have proceeded under general authorization rather than a project-specific individual permit.
Colorado Wetland Permit Search FAQs
How do I search for a wetland permit in Colorado?
Search both the Colorado Water Quality Control Division’s dredge-and-fill program and the U.S. Army Corps of Engineers regulatory databases. Also check the county or municipality for related floodplain, grading, stormwater and development approvals.
Are Colorado wetland permits public records?
Many permit, authorization, public-notice and jurisdiction records are publicly accessible. If a specific Colorado WQCD application file is not available through an online resource, request the records from the division’s records center.
What is a Section 404 permit?
Section 404 of the federal Clean Water Act regulates certain discharges of dredged or fill material into waters of the United States. The U.S. Army Corps of Engineers administers the permit program.
What is an Approved Jurisdictional Determination?
An Approved Jurisdictional Determination is a written USACE determination identifying the presence or absence of federally regulated aquatic resources within a review area. It is not itself a permit to discharge dredged or fill material.
Does Colorado regulate wetlands that are not federally jurisdictional?
Yes. Colorado created a state dredge-and-fill authorization program after federal wetland jurisdiction was narrowed. Qualifying state waters can require Colorado authorization even when they are outside federal Section 404 jurisdiction.
What is Colorado Regulation 87?
Regulation 87 is Colorado’s Dredge and Fill Control Regulation. It establishes the state framework for authorization of regulated dredge-and-fill activities in state waters, including general and individual authorization pathways.
When did Colorado’s current general authorizations become effective?
Colorado’s general conditions and general authorizations became effective September 1, 2026. The separate Isolated State Waters General Authorization became effective February 6, 2026.
Can I search a wetland permit by street address?
Sometimes, but environmental records are often indexed by project name, coordinates, waterbody, applicant or agency file number rather than a standard street address. Start with the address, then use coordinates and project identifiers if needed.
Does a wetland permit replace a floodplain or grading permit?
No. Federal or state wetland authorization does not automatically replace county or municipal floodplain, grading, stormwater, land-use, right-of-way or building approvals.
What should I do if I cannot find the application online?
Gather the project name, applicant, location, county, approximate date and any agency file number. Then contact the responsible USACE district or request the relevant records from Colorado’s Water Quality Control Division.
Is the federal WOTUS definition changing in 2026?
Federal agencies are pursuing rulemaking. A supplemental proposed WOTUS rule was published September 9, 2026, but a proposed rule is not the same as a final effective rule. Check EPA’s current implementation page and USACE guidance for the latest federal status.

EPA Waters of the United StatesWhat to Do Next
If you are researching an existing project, begin with the USACE public regulatory database and the Colorado dredge-and-fill program. Save every project number you find and use those identifiers to request the underlying files.
If you are planning new work, do not wait until grading or construction begins to resolve wetland jurisdiction. Confirm the aquatic-resource boundaries, determine which federal and state authorization paths apply, and check the local permit requirements for the same site.
For consequential development, property-purchase or compliance decisions, use the agency record itself and obtain appropriate environmental, engineering or legal guidance when the jurisdiction or permit scope is uncertain.
