OLR Bill Analysis 
sHB 7174  
 
AN ACT CONCERNING RIPARIAN AREAS.  
 
SUMMARY 
This bill broadens the applicability of the state’s Inland Wetlands and 
Watercourses Act (IWWA) to include the area immediately adjacent to 
and extending outward from a wetland or watercourse boundary by at 
least 100 feet (the “riparian area”). 
Consequently, the bill correspondingly expands the authority of 
municipal inland wetlands agencies and the Department of Energy and 
Environmental Protection (DEEP) to regulate activities in these areas, 
which generally entails reviewing activity proposals, issuing permits, 
and conducting enforcement actions. It relatedly requires DEEP to 
inventory or index riparian areas and adopt any necessary regulations 
to protect them, as the law already requires it to do for wetlands and 
watercourses. 
The bill also makes the following additional changes to the IWWA: 
1. explicitly (a) excludes native vegetation clear cutting in wetland 
or watercourse areas from an “as of right” use and (b) includes 
revegetation in riparian areas with native vegetation and 
removing invasive species as a nonregulated permitted use; 
2. adds public drinking water supply areas and cold water habitat 
streams to the list of things the commissioner must consider 
when carrying out her responsibilities under the IWWA;  
3. allows an inland wetlands agency to deny or condition an 
application for a regulated activity outside of a wetlands, 
watercourse, or riparian area if it will likely impact the area’s 
chemical or thermal characteristics, as an agency already may do 
for the physical characteristics of wetlands or watercourses; and   2025HB-07174-R00-BA.DOCX

4. makes many technical and conforming changes, including those 
to effectuate its application to riparian areas such as, among other 
things, allowing aggrieved parties to appeal decisions about 
activities in riparian areas and requiring the applicants for 
activities in these areas that are within a water company’s 
watershed to notify the company and public health department. 
Lastly, the bill requires the DEEP commissioner to prescribe, either 
by permit or through adopting regulations, conditions for existing 
fishways built for dams in navigable waters that are not regulated by 
the Federal Energy Regulatory Authority (i.e. certain hydropower 
dams) to ensure safe, timely, and effective fish passage and protect 
aquatic habitat. The conditions must be implemented and paid for by 
the dam’s owner or operator (§ 12). 
EFFECTIVE DATE: October 1, 2025, except the provision adding the 
riparian area definition to the IWWA is effective July 1, 2025.  
IWWA EXPANSION — RIPARIAN AREA 
The IWWA requires municipalities to regulate activities in inland 
wetlands and watercourse areas within their boundaries through an 
inland wetlands agency or empowering another board or commission 
to carry out its responsibilities. DEEP has the regulatory authority over 
state actions in these areas and for municipalities without an inland 
wetlands agency. 
The bill expands this oversight to generally include operations 
within, or use of, a riparian area, including the removal or deposition of 
material, or any obstruction, construction, alteration, or pollution, of the 
riparian area.  
Updating Regulations  
Existing law requires DEEP to adopt regulations to protect wetlands 
and watercourses. Under the bill, these regulations must also include 
riparian areas. Similarly, municipal inland wetlands agencies (or the 
applicable board or commission), as under existing law for wetlands 
and watercourses, must adopt regulations necessary to protect riparian  2025HB-07174-R00-BA.DOCX

areas, either individually, or through districts.  
As for wetlands and watercourses, the bill requires the local 
regulations to prescribe (1) how riparian area boundaries are set or 
changed, (2) how to apply for a regulated activity in these areas, (3) 
notice requirements, (4) criteria for and the process of reviewing 
applications, and (5) administration and enforcement requirements. (It 
subjects proposed activities in riparian areas to the same statutory 
application and review requirements and potential penalties for 
violations as already apply for wetlands and watercourses activities (see 
BACKGROUND). )  
NATIVE VEGETATION 
Regulated Activities  
The bill explicitly includes an operation in or use of a wetland, 
watercourse, or riparian area involving native vegetation removal as a 
“regulated activity” under the IWWA, meaning these activities 
generally cannot be done without a permit. The bill does not, however, 
specify what “native vegetation” is. 
Permitted Activities  
As of Right. By law, certain operations and uses are permitted “as of 
right” in wetlands and watercourses. Subject to certain exceptions, these 
include, among other things, (1) grazing, farming, nurseries, gardening, 
and harvesting crops and certain farm ponds essential to the farming 
operation; (2) activities DEEP does for restoration, enhancement, or 
mosquito control; and (3) uses incidental to the enjoyment and 
maintenance of residential property. 
The bill exempts from being an “as of right” use clear cutting native 
vegetation (1) unless it is to expand agricultural crop land, as is already 
the case for timber clear cutting, or (2) within 10 feet of a wetlands or 
watercourse for incidental residential property enjoyment or 
maintenances uses. 
Unregulated Uses. The IWWA also allows certain activities in areas 
under its jurisdiction (including riparian areas under the bill) as  2025HB-07174-R00-BA.DOCX 
 
Researcher: DD 	Page 4 	4/14/25 
 
“nonregulated uses” if they do not disturb the natural and indigenous 
character of the area by removing or depositing material, altering, or 
obstructing water flow, or polluting. Examples include conservation of 
natural resources, outdoor recreation, and dry hydrant installation. The 
bill specifies that (1) removing or depositing material, for determining 
if an activity is a nonregulated use, includes native vegetation removal 
and (2) revegetating riparian areas with native vegetation and removing 
invasive species is considered natural resource conservation. 
BACKGROUND 
Inland Wetlands and Watercourses  
By law, inland “wetlands” are land areas that consist of any of the 
soil types designated as poorly drained, very poorly drained, alluvial, 
and floodplain by the U.S. Department of Agriculture Natural 
Resources Conservation Service’s National Cooperative Soils Survey, 
which includes submerged land, but not land bordering or lying 
beneath tidal waters. “Watercourses” are, in general, rivers, streams, 
brooks, waterways, lakes, ponds, marshes, swamps, bogs, and all other 
bodies of water, natural or artificial, vernal, or intermittent, public, or 
private, which are in, flow through, or border the state or any portion of 
it (CGS § 22a-38). 
Permit Application Process 
By law, anyone proposing to do a regulated activity on an inland 
wetland or watercourse must apply for a permit from the inland 
wetlands agency of the town or towns where the wetland or 
watercourse is located. Public hearings on these regulated activities may 
be held, but only if (1) the agency determines the activity may 
significantly affect wetlands or watercourses, (2) at least 25 people sign 
a petition requesting a hearing and it is filed with the agency within 14 
days after the application is received, or (3) the agency finds that a 
hearing would be in the public interest. 
By law, when an application receives a public hearing or the agency 
finds that the proposed activity may have a significant impact on 
wetlands or watercourses, it cannot issue a permit unless the DEEP 
commissioner finds, on the basis of the record, no feasible and prudent  2025HB-07174-R00-BA.DOCX 
 
Researcher: DD 	Page 5 	4/14/25 
 
alternative exists.  
When an application is denied on a finding that there may be feasible 
and prudent alternatives to the proposed regulated activity that would 
have a less adverse impact on wetlands or watercourses, the 
commissioner or the agency must propose on the record the types of 
alternatives that the applicant may investigate. 
Enforcement 
State law permits municipal inland wetlands agencies, if they 
determine that a person is violating the IWWA or the associated local 
ordinance, to issue cease-and-desist orders, impose civil fines of up to 
$1,000 per offense, or ask a court to impose issue certain orders or 
penalties. Higher penalties apply for willful or knowing violations 
(CGA § 22a-44).
