Rules and Regulations Governing the Protection and Management of Freshwater Wetlands in the Vicinity of the Coast

A.These Rules and Regulations (Rules) are promulgated by the Coastal Resources Management Council (CRMC) pursuant to R.I. Gen. Laws § 46-23-6, as amended, and consistent with R.I. Gen. Laws §§ 2-1-18 through 2-1-20.1 and 2-1-27.

B.The CRMC shall be responsible for the protection and management of freshwater wetlands in the vicinity of the coast as depicted on the map in § 9.22 of this Part. The CRMC may at any time, when necessary, consult with and/or coordinate its responsibilities and duties with the DEM.

C.These Rules are promulgated by the CRMC to:

1.Administer and enforce R.I. Gen. Laws §§ 46-23-6(2)(iii)(E) and (iv), as amended, in regard to freshwater wetlands in the vicinity of the coast; and

2.Preserve, protect, and restore the purity and integrity of all freshwater wetlands, buffers and floodplains located in the vicinity of the coast within the State of Rhode Island so that these resources shall be available for all beneficial purposes, and thus protect the health, welfare, and general wellbeing of the people and the environment of Rhode Island.

A.The declarations of intent and public policy enumerated in R.I. Gen. Laws §§ 2-1-18 and 2-1-19 (Freshwater Wetlands Act or Act) are hereby adopted as the administrative findings upon which these Rules are based.

B.Consistent with these declarations, the CRMC makes the following findings:

1.Freshwater wetlands, buffers and floodplains are ecological systems performing functions that directly benefit the health, welfare and general wellbeing of people and the environment.

2.Any such freshwater wetland, buffers and floodplains functions as an integrated ecological system, no portion or component of which is less worthy of regulatory protection than the system as a whole. Buffers and floodplains are important integral components of the flowing body of water, or the freshwater wetland with which they are associated. It has been established that maintaining lands adjacent to freshwater wetlands as naturally vegetated buffers protects the functions and values of wetlands and that such buffers in and of themselves perform vital ecological functions.

3.Freshwater wetlands, buffers and floodplains perform specific functions and support specific values, including but not limited to the following:

a.Wildlife and wildlife habitat: Freshwater wetlands and buffers are important areas for the production and maintenance of a diversity of wildlife. Freshwater wetlands and buffers provide habitat for individual species and communities of animals and plants. Animals include both game and non-game species, which may be either obligate or facultative and which may be permanent residents, or they may be seasonal or transient in nature. Freshwater wetlands and buffers serve as travel corridors; nesting, feeding, resting, nursery and brood-rearing sites; drinking water sources and escape cover; and seasonal breeding, migration and over-wintering habitat for wildlife. Freshwater wetlands and buffers provide critical habitat for some plant and animal species and also provide habitat for rare animal and rare plant species.

b.Recreation and aesthetics: Freshwater wetlands and buffers support active and passive recreational and aesthetic values that are important to the general public. They provide the opportunity for recreational activities, including but not limited to: hunting, fishing, trapping, cross-country skiing, ice skating, boating, water-skiing, canoeing, camping, swimming, bicycling, hiking, walking, horseback riding, harvesting of natural foods or plant materials, bird watching and other animal observation, education and nature studies, and photography. Aesthetic values include but are not limited to the visual, aural and cultural qualities of the freshwater wetland and buffer. Without limitation, these include the freshwater wetland’s and buffer’s prominence as a distinct feature in the local area, including its value as open space; whether it is a rare freshwater wetland type; whether it offers or provides suitable habitat for any rare animal or rare plant species; whether it has any outstanding or uncommon geomorphologic features; or whether it contains or may contain material of archaeological, historical, or cultural significance.

c.Flood protection: Freshwater wetlands, buffers, setbacks and floodplains protect life and property from flooding and flood flows by storing, retaining, metering out and by otherwise controlling flood waters from storm events. Freshwater wetlands, buffers and floodplains also control the damaging impacts of flood flows by providing frictional resistance to flood flows, by dissipating erosive forces, and helping to anchor the shoreline.

d.Surface water and groundwater: Freshwater wetlands and buffers provide and maintain surface and groundwater supplies by acting as recharge or discharge areas, and, in the case of some ponds, acting as surface water reservoirs. Although groundwater recharge and discharge functions and values may vary seasonally, freshwater wetlands and buffers, either individually or cumulatively, may be an important factor in replenishing ground and surface water supplies, maintaining stream flows, transporting surface waters, and storing and distributing surface waters and groundwater during periods of drought.

e.Water quality: Freshwater wetlands and buffers protect and maintain water quality by retaining and removing nutrients; filtering and removing pollutants; removing sediments; producing oxygen; reducing turbidity; maintaining or modifying stream flow; maintaining temperature and oxygen regimes in both standing and flowing surface waters; and providing and maintaining safe drinking water supplies.

4.The cumulative impact of incremental alterations to freshwater wetlands, buffers and floodplains that occur at different times or in different locations within the same system, or both, may constitute a significant alteration, even if a single proposed alteration may not in and of itself constitute a significant alteration.

5.Consistent with the purposes of the Act, it is the public policy of the State to preserve the purity and integrity of all freshwater wetlands, buffers and floodplains in Rhode Island. Random, unnecessary or undesirable alteration of any freshwater wetland, buffer or floodplain is contrary to the Act and not in the best public interest because of the adverse impacts of such alterations on their functions and values.

6.The CRMC recognizes that dams have created freshwater wetlands and buffers that may provide important wildlife habitats and recreational areas and may provide other important functions, values and benefits such as flood storage areas. The CRMC recognizes that dams may also be historic resources (listed on the National Register of Historic Places or eligible for listing) and that preservation of such resources is desirable. Also, consistent with its responsibilities under R.I. Gen. Laws Chapter 46-19 et seq., the DEM has determined that many dams in the State are in disrepair and may present safety hazards to the public. The CRMC hereby acknowledges that, as a result of an analysis of alternatives for addressing a dam’s state of disrepair, the removal or substantial alteration of a dam may be required by the DEM for reasons of public safety. The CRMC finds that the removal or substantial alteration of a dam for public safety reasons may be deemed consistent with the authority and purposes of these Rules provided that no other feasible alternative is available and impacts related to the dam’s removal or alteration are assessed and acceptably mitigated in accordance with these Rules.

Gen. Laws § 2-1-22(k) for farmers conducting normal farming and ranching activities.

9.5.3Freshwater Wetlands in The Vicinity Of The Coast

A.The freshwater wetlands jurisdictional boundary map (§ 9.22 of this Part) that depicts the jurisdictional boundary between freshwater wetlands and freshwater wetlands in the vicinity of the coast is available for review at the CRMC and on the Department website. Freshwater wetlands in the vicinity of the coast are under the exclusive jurisdiction of the CRMC with these exceptions:

1.The DEM shall retain authority over farming-related projects and activities undertaken by farmers, as defined in § 9.4(A) of this Part, involving freshwater wetlands in the vicinity of the coast consistent with R.I. Gen. Laws §§ 2-1-22(i), 2-1-22 (j) and 46-23-6(2)(iv).

2.The DEM shall retain authority over any permits issued prior to January 1, 2002, that are the subject of an outstanding compliance order or other formal administrative, civil or criminal legal action initiated by the DEM for the purpose of litigating or settling that action.

3.The DEM shall retain authority over any permits or permit applications acted upon by the DEM prior to January 1, 2002, to permit the DEM to defend or settle any legal proceedings brought against it as a result of those actions.

4.Any compliance order issued or other civil or criminal enforcement action taken by the DEM prior to August 18, 1999, shall continue to be subject to the DEM authority and to be governed by the Rules and Regulations in effect at the time the order was issued or action taken.

5.Permits issued by the DEM for projects that lie on or that straddle the jurisdictional boundary shall be administered by the DEM in accordance with § 9.3(C) of this Part below.

6.Projects and activities located within the boundary of the CRMC Salt Pond Region Special Area Management Plan (SAMP), Part 3 of this Subchapter, or the Narrow River SAMP, Part 4 of this Subchapter, and which constitute a watershed activity as defined therein may be subject to CRMC requirements for larger buffers or setbacks in accordance with Part 3 and Part 4 of this Subchapter.

9.5.4Projects That Lie on Or Cross The Jurisdictional Boundary

A.Applications for linear projects such as road or utility rights of way lying on the jurisdictional boundary will be reviewed as follows:

1.If the project is located entirely or partially either within a CRMC Special Area Management Plan or within two hundred feet (200’) of a coastal shoreline feature, as defined by CRMC, then CRMC shall be the freshwater review agency.

2.If the project is located entirely outside of any CRMC Special Area Management Plan and beyond two hundred feet (200’) of a coastal shoreline feature, as defined by CRMC, then the DEM shall be the freshwater review agency.

B.Applications for projects that cross or fall on both sides of the jurisdictional boundary will be reviewed as follows:

1.If all of the freshwater wetlands are located seaward of the boundary, then CRMC shall be the freshwater wetland review agency.

2.If all of the freshwater wetlands are located inland of the boundary, then the DEM shall be the freshwater wetland review agency.

3.If the wetlands lie on both sides of the jurisdictional boundary and the project is non-linear in character, then:

a.Where the project is located entirely or partially either within a CRMC Special Area Management Plan or within two hundred feet (200’) of a coastal shoreline feature, as defined by CRMC, then CRMC shall be the freshwater wetland review agency; or

b.Where the project is entirely outside of any Special Area Management Plan and is beyond two hundred feet (200’) of a coastal shoreline feature, as defined by CRMC, then the DEM shall be the freshwater wetland review agency.

4.For linear projects that are on both sides of the jurisdictional boundary, the DEM and CRMC shall jointly determine which agency will serve as the freshwater wetland review agency. This determination shall be made on a case-by-case basis in response to a written request from an applicant to CRMC, and be based on the following: the extent and location of the freshwater wetland or wetlands, the area and proximity of potential land disturbance, and the guidelines set forth in any applicable watershed plan. Within ten (10) business days of the receipt of a request for clarification from an applicant, the agency that retains jurisdiction shall so inform the applicant. Upon written notice to the applicant, the agency may extend the ten (10) day deadline for up to an additional ten (10) business days for any reason. Although the goal of these provisions is to promote the designation of a single review agency, in the event that a project includes potential freshwater wetland, buffer or floodplain alterations on both sides of the jurisdictional boundary, the DEM and CRMC reserve the right to jointly exercise their authority.

C.The permitting agency for a project that is on the jurisdictional boundary or on both sides of the jurisdictional boundary shall renew, modify, transfer and enforce the permit in accordance with the applicable agency Rules and Regulations that were in effect at the time the permit was issued.

9.7.1Freshwater Wetland and Buffer Protection Standards

A.General freshwater wetland protection standard

All projects and activities subject to this Part shall be designed and carried out to avoid alteration of freshwater wetlands.

B.Freshwater wetland buffer standard

1.This Rule, § 9.7.1(B) of this Part, establishes buffer standards for projects and activities carried out within a jurisdictional area. As defined in § 9.4(A) of this Part, a buffer is an area of undeveloped vegetated land adjacent to a freshwater wetland that is to be retained in its natural undisturbed condition or an area of land that is to be created to resemble a naturally occurring vegetated area. Undeveloped vegetated land is an area of land that does not consist of buildings, impervious surfaces, bare gravel, lawn, or landscaped areas.

2.Buffer zones, as defined in § 9.4(A) of this Part, are the land areas contiguous to freshwater wetlands. The width of a buffer zone is measured in accordance with the procedures specified in § 9.23 of this Part.

3.Protection of existing freshwater wetland buffers. All projects and activities shall be designed and carried out to avoid alteration of buffers within buffer zones, except as provided for in § 9.7.1(B)(1)(d) of this Part, below. The buffer within a designated buffer zone shall consist of:

a.All undeveloped vegetated land; and

b.Any area to be newly created to resemble buffer pursuant to § 9.7.1(B)(4) of this Part, below.

4.Creation of new buffer on existing disturbed property

a.When a project or activity is proposed within a buffer zone that does not consist entirely of undeveloped vegetated land, new buffer area may be required to be created within a portion of the buffer zone to resemble a naturally occurring vegetated area.

b.A project or activity that cannot, due to site constraints, avoid intrusion into the buffer zone shall be designed and carried out to avoid alteration of the existing buffer as well as meet the following minimum targets for creation of new buffer contiguous to freshwater wetland or existing buffer on the subject property:

(1)For single-family houses and other development proposed on property with no existing buildings, the minimum target for total buffer width (existing undeveloped vegetated land plus created buffer) is:

(AA)Fifty percent (50%) of the applicable buffer zone width from § 9.23 of this Part, not to exceed fifty feet (50’), on lots greater than or equal to one (1) acre, or

(BB)Fifteen feet (15’), on lots less than one (1) acre.

(2)For proposed projects or activities on property that is greater than or equal to three (3) acres, that is not a single-family residential lot of record, that contains one (1) or more existing structures, and where the proposed land disturbance total is greater or equal to ten thousand (10,000) square feet, the minimum target for total buffer width is:

(AA)Twenty five feet (25’) in the non-urban River Protection Regions 1 and 2 (See § 9.24 of this Part); or

(BB)Fifteen feet (15’) in the urban region (See § 9.24 of this Part).

c.Creation of new buffer may be accomplished by the planting of vegetation or by allowing the area to naturally revegetate, at the discretion of the CRMC. The CRMC may require plantings as a condition of a permit, and such area shall be defined as buffer. When creating buffer, the CRMC may allow certain areas to remain clear in order to accommodate existing utilities, drainage easements, reasonable access to existing developed shoreline features, property accessories, or conditions where re-vegetation would require the removal or threaten the integrity of existing structures.

5.Residential infill lot standard

a.This standard shall apply to proposed new construction on an individual residential lot of record, as of the effective date of these Rules, where the lot meets the following conditions:

(1)Has frontage on an existing road;

(2)Has adjacent lots on both sides that are developed;

(3)Is less than or equal to one (1) acre in size; and

(4)Is undeveloped vegetated land.

b.When the proposed new construction cannot meet the buffer and the setback standards for the freshwater wetlands of concern, the proposed structure foundation is to be located no closer to the edge of the subject freshwater wetland than the structure foundation on the adjacent lot that is farthest from the subject freshwater wetland edge. The project shall be designed to avoid alteration of the remaining buffer, and in no case shall the remaining buffer be less than that shown in § 9.7.1(B)(5)(c) of this Part, below.

c.Table 1: Minimum buffer and setback distances

6.Buffer management and maintenance: A buffer shall be retained in a natural vegetative, undisturbed condition to protect the functions and values of the freshwater wetlands and buffer. Certain activities related to buffer management may be authorized as exempt activities pursuant to the provisions and conditions in § 9.6 of this Part.

C.Setback standards

1.Setback standards for primary structures. Primary structures (e.g., residential dwellings, commercial/industrial structures, schools, churches, etc.) must be located to meet a setback distance of no less than the buffer width plus twenty feet (20’). Accessory structures must be located to meet a setback distance of no less than the buffer width plus five feet (5’).

2.Setbacks for onsite wastewater treatment systems: The setback requirements for the components of an onsite wastewater treatment system are specified in the DEM’s Rules Establishing Minimum Standards Relating to the Location, Design, Construction and Maintenance of Onsite Wastewater Treatment Systems, 250-RICR-150-10-6, in effect at the time of application. A leachfield and the required ten foot (10’) cleared zone around it shall be located outside of the buffer.

D.Rare or endangered species standard

No project or activity may result in degradation of the natural characteristics of any rare freshwater wetland type; likewise, no project or activity may reduce the ability of a freshwater wetland or buffer to ensure the long-term viability of any rare or endangered animal or plant species incorporated by reference in §§ 9.3(A) and (B) of this Part or under the Federal Endangered Species Act.

E.Flood protection standard

1.Flood storage capacity: Projects and activities taking place in a floodplain shall not result in any net reduction in flood storage capacity and shall not reduce the rate at which floodwater is stored by the floodplain.

2.Floodway obstruction: Projects and activities taking place within or adjacent to rivers or streams shall not encroach into floodway limits with any fill, structure or other development.

F.Surface water and groundwater diversion standard

Projects and activities shall not adversely affect the flow of groundwater or surface water into or out of any freshwater wetland and shall not result in obstruction of, or the reduction in storage capacity of, any area subject to flooding or area subject to storm flowage.

G.Stormwater management standard

Projects and activities shall meet the minimum standards in the Stormwater Management, Design, and Installation Rules, 250-RICR-150-10-8, or for single-family lots of record the “RI Stormwater Management Guidance for Individual Single Family Residential Lot Development” for the recommended and primary means to achieve this standard.

H.Erosion and sedimentation control standard

Projects and activities shall be designed and carried out in a manner that prevents soil erosion and sedimentation consistent with the Stormwater Management, Design and Installation Rules, § 250-RICR-150-10-8.16.

I.Water quality standard

Projects shall not cause or contribute to a violation of any State water quality standard for surface water or groundwater or contribute to significant degradation of surface water or groundwater resources.

Variances shall only be granted if the applicant demonstrates and can document that all of the following criteria in § 9.7.3(A)(2) of this Part have been met. No variance is available for standards specified in §§ 9.7.1(G) through (I) of this Part.

2.All reasonable alternatives to avoid and minimize impacts to freshwater wetlands, buffers, floodplains, areas subject to flooding and areas subject to storm flowage have been pursued and incorporated into the project design and application as follows

a.Avoidance: All persons must satisfactorily demonstrate to the CRMC in the form of a written narrative that all probable impacts to freshwater wetlands, buffers, floodplains, areas subject to flooding and areas subject to storm flowage functions and values have been avoided to the maximum extent possible. The written narrative must describe what steps were taken to avoid impacts to freshwater wetlands, buffers, floodplains, areas subject to flooding and areas subject to storm flowage. At a minimum, applicants must consider and address the following issues:

(1)Whether the primary proposed activity is water-dependent or whether it requires access to freshwater wetlands, buffers, floodplains, areas subject to flooding or areas subject to storm flowage as a central element of its primary purpose (e.g., a dock);

(2)Whether any areas within the same property or other properties owned or controlled by the applicant could be used to achieve the project purpose without altering the natural character of any freshwater wetlands, buffers, floodplains, areas subject to flooding or areas subject to storm flowage;

(3)Whether any other properties reasonably available to, but not currently owned or controlled by, the applicant could be used to achieve the project purpose while avoiding freshwater wetlands, buffers, floodplains, areas subject to flooding or areas subject to storm flowage alterations. A property is reasonably available if, in whole or in part, it can be acquired without excessive cost, taking individual circumstances into account, or, in the case of property owned or controlled by the same family, entity, group of affiliated entities, or local, State or Federal government, may be obtained without excessive hardship;

(4)Whether alternative designs, layouts or technologies could be used to avoid freshwater wetlands, buffers, floodplains, areas subject to flooding or areas subject to storm flowage or impacts on functions and values on the subject property or whether the project purpose could be achieved on other property that is reasonably available and would avoid freshwater wetlands, buffers, floodplains, areas subject to flooding or areas subject to storm flowage;

(5)Whether the applicant has made any attempts (and if so what they were) to avoid alterations to freshwater wetlands, buffers, floodplains, areas subject to flooding or areas subject to storm flowage by overcoming or removing constraints imposed by zoning, infrastructure, parcel size or the like; and

(6)Whether the feasible alternatives that would not alter the natural character of any freshwater wetlands, buffers, floodplains, areas subject to flooding or areas subject to storm flowage on the subject property or on property that is reasonably available, if incorporated into the proposed project would adversely affect public health, safety or the environment.

b.Minimization: For any impact to freshwater wetlands, buffers, floodplains, areas subject to flooding or areas subject to storm flowage that cannot be avoided, the applicant must satisfactorily demonstrate in the written narrative to the CRMC that the impact to their functions and values have been reduced to the maximum extent possible. At a minimum, applicants must consider and address the following issues:

(1)Whether the proposed project is necessary at the proposed scale or whether the scale of the wetland alteration could be reduced and still achieve the project’s purpose;

(2)Whether the proposed project is necessary at the proposed location or whether another location within the site could achieve the project’s purpose while resulting in less impacts to the freshwater wetlands, buffers, floodplains, areas subject to flooding or areas subject to storm flowage;

(3)Whether there are feasible alternative designs, layouts, densities or technologies, that would result in less impacts to the freshwater wetlands, buffers, floodplains, areas subject to flooding or areas subject to storm flowage while still achieving the project’s purpose; and

(4)Whether a reduction in the scale or relocation of the proposed project to minimize impact to the freshwater wetlands, buffers, floodplains, areas subject to flooding or areas subject to storm flowage would result in adverse consequences to public health, safety or the environment.

3.All applicable review criteria specified in § 9.7.2 of this Part have been satisfied.

4.Due to the conditions at the project site, the applicable standard(s) cannot be met.

5.The relief requested by the applicant is the minimum variance to the applicable standard(s) necessary to allow a reasonable alteration or use of the site as required by §§ 9.7.3(A)(2)(a) and (b) of this Part above;

6.The requested variance to the applicable standard(s) is not due to any prior action of the applicant or the applicant’s predecessors in title.

7.Due to the conditions of the project site in question, the standard(s) will cause the applicant an undue hardship. In order to receive relief from an undue hardship an applicant must demonstrate inter alia the nature of the hardship and that the hardship is shown to be unique or particular to the site. Mere economic diminution, economic advantage, or inconvenience does not constitute a showing of undue hardship that will support the granting of a variance.

B.Variance criteria for public and governmental bodies

1.Unless eligible as an exemption pursuant to § 9.6 of this Part or eligible for approval under a freshwater wetlands general permit (see § 9.10 of this Part), public or governmental projects or activities that do not meet the standards specified in §§ 9.7.1(A) through (F) are also required to obtain a variance in order to receive a permit from the CRMC. Variances shall be granted if the applicant demonstrates and documents that all of the following criteria have been met. No variance is available for standards specified in §§ 9.7.1(G) through (I) of this Part.

a.All reasonable alternatives to avoid and minimize impacts to freshwater wetlands, buffers, floodplains, areas subject to flooding and areas subject to storm flowage have been pursued and incorporated into the project design and application as required in §§ 9.7.3(A)(2)(a) and (b) of this Part, above;

b.All applicable review criteria specified in § 9.7.2 of this Part have been satisfied;

c.Due to the conditions at the project site, the applicable standards cannot be met; and

d.The proposed project serves a necessary public purpose that provides benefits to the public.

C.Alternative configuration of vernal pool buffer zone

Where an applicant is unable to meet the buffer standard associated with a vernal pool, the applicant may propose an alternative buffer zone configuration that is protective of the functions and values of the associated vernal pool. This alternative configuration will be reviewed on a case-by-case basis by the CRMC through the variance process specified in § 9.7.3(A) of this Part.

D.In those instances where a variance would be obviated or reduced if a variance for a setback were acquired from a local municipality, the applicant must first exhaust his or her remedies before the local municipality prior to submitting an application for a permit to the CRMC.

E.Relief from a standard does not remove the applicant’s responsibility to comply with all other requirements pursuant to the Act and this Part.

§ 9.8 of this Part describes general application requirements and provisions applicable to all application types unless otherwise specified herein. Additional requirements for each application type are described within §§ 9.9 through 9.14 of this Part.

3.Those plant species listed as having a wetland indicator status of facultative wetland (FACW), facultative (FAC) or facultative upland (FACU) according to the National Wetland Plant List: State of Rhode Island, where such plants are present along with other clear hydrologic indicators of wetland.

C.Where no distinct edge is apparent based upon examination of vegetation alone (e.g., the plant community is transitional in nature and dominated by species having an indicator status of FACW, FAC or FACU), other hydrologic indicators must be considered before determining the location of the landward edge of vegetated freshwater wetlands. Where such indicators are present, the FACW, FAC, or FACU plant species are considered hydrophytes/hydrophytic vegetation; however, the landward edge of vegetated wetland in such transitional areas is located where other hydrologic indicators are no longer present.

D.Other hydrologic indicators are those characteristics, other than vegetation, which provide evidence that an area is continuously or periodically saturated, inundated, flooded, or ponded; has standing or slowly moving water; or frequently collects surface run-off or drainage. Examples of other hydrologic indicators include, but are not limited to, the following: (Note: Those features in §§ 9.21.1(D)(3), (5) and (7) through (9) are valid indicators only when at least one (1) additional hydrologic indicator is present.)

1.Morphologic features or properties associated with hydric soils in accordance with the most recent version of the Field Indicators for Identifying Hydric Soils in New England.

2.Visual observation of soil saturation within twelve inches (12”) of the soil surface (considering both seasonal and recent weather conditions);

3.Distinct water marks on vegetation or other fixed objects;

4.Sulfitic materials (H2S – rotten egg odor) within twelve inches (12”) of the soil surface;

5.Mound and pool microtopography;

6.Patches of peat mosses (Sphagnum spp.)

7.Soil morphologic evidence of recent or periodic flooding (e.g., stratification associated with flood plains);

8.Visual observation of surface inundation (considering both seasonal and recent weather conditions);

9.Dark or water-stained leaves on the ground surface;

10.Drift or wrack lines of water-borne materials;

11.Wetland drainage features or patterns such as scoured channels;

12.Morphological plant adaptations (e.g., buttressed trees trunks, adventitious roots, exposed or shallow root systems);

13.Distinct or prominent pore linings (oxidized rhizopheres) along live roots within twelve inches (12”) of the soil surface.

E.For purposes of locating and identifying the edge of vegetated freshwater wetlands for applications submitted to the CRMC, the CRMC will accept the methodology described and incorporated within the Corps of Engineers Wetlands Delineation Manual, Technical Report Y-87-1, January, 1987, Prepared for: Department of The Army, U.S. Army Corps of Engineers, and Regional Supplement to the Corps of Engineers Wetlands Delineation Manual Northcentral and Northeast Region, 2012, prepared by the U.S. Army Corps of Engineers, Technical Report 12-0 ERDC/EL under the following conditions:

1.The use of this methodology is intended to facilitate the location and identification of the edge of "vegetated" freshwater wetlands, but must not be interpreted as redefining freshwater wetlands regulated under the Act and these Rules.

2.All edge locations and delineations are subject to the CRMC’s review and acceptance under the procedures set forth in § 9.9.2 of this Part for requests to determine the presence of jurisdictional area. Accordingly, all requests to verify the edge of these types of freshwater wetlands will require on-site inspection and analysis.

3.Areas discovered during the delineation of freshwater wetlands which appear to have altered conditions (e.g., removal of vegetation, ditching, draining, filling or other alterations that have changed or appear to change normal conditions) must be documented.

9.21.2.Flowing and Standing Water Freshwater Wetlands

A.The edge of rivers, streams, intermittent streams, ponds, vernal pools, areas subject to storm flowage, areas subject to flooding and other areas dominated by open or flowing water shall be identified as follows:

1.The edge of rivers, streams, intermittent streams, ponds, vernal pools, areas subject to storm flowage, areas subject to flooding and other areas dominated by open or flowing water shall be the ordinary high water mark of standing or flowing water. The ordinary high water mark is the line separating land flooded at high water and land exposed at high water. This line may be determined and documented by using recorded hydrologic data (e.g., data obtained from site specific planning and design documents; in-stream flow studies; stream gauge data; the CRMC’s file data; or flood data), or, in the absence of these, by observing physical characteristics, such as evidence of a clear demarcation line between terrestrial and aquatic conditions as a result of standing or flowing water; shelving; permanent watermarks and stains on woody vegetation or other fixed objects, such as bridges, stones, walls, docks, or piers; changes in the character of the soil; the presence of water-borne natural litter and debris; evidence of surface scouring; or other appropriate means.

2.The edge of any pond and incoming or outgoing flowing body of water shall be that location where characteristics associated with a lentic ecosystem and a lotic ecosystem are both present.

9.21.3Floodplain

A.The edge of any flood plain shall be identified as the maximum horizontal extent of flood water which will result from the statistical one hundred (100) year frequency storm event.

B.The one hundred (100) year flood plain elevation shall be determined by the most recently available flood profile data prepared under the National Flood Insurance Program of the Federal Emergency Management Agency (FEMA); or

C.In instances where FEMA has not established the elevation of the one hundred (100) year floodplain, the floodplain elevation and floodplain edge shall be determined through calculations completed by a registered professional engineer. These calculations shall be based upon:

1.Calculation of one hundred (100) year flood discharge based on a one hundred (100) year rainfall event identified in the Stormwater Management, Design, and Installation Rules, 250-RICR-150-10-8, and a generally accepted hydrologic model including, but not limited to, TR-20, TR-55 or commercially available software based on TR-20 or TR-55. In certain cases involving very large watersheds an acceptable regression equation methodology may be used, such as a USGS regression for Rhode Island; and

2.Using the flood discharge established above in § 9.21(C)(1) of this Part, along with detailed topography mapping, prepare a determination of peak one hundred (100) year flood elevation using a widely accepted hydraulic model such as the U.S. Army Corps of Engineers’ Hydrologic Engineering Center River Analysis System (HEC-RAS). Once this elevation is established the edge of the one hundred (100) year floodplain must be plotted on a detailed site topography map.

D.The flood plain edge must coincide with the flood plain elevation and topographic contour elevations as depicted on submitted plans. Transposing flood boundaries from FEMA maps by using horizontal scaling is not acceptable for plans submitted to the CRMC. Identification of the one hundred (100) year flood elevation must be expressed in North American Vertical Datum 1988 (NAVD88).

9.21.4Floodway

A.The edge of floodway for all rivers and streams will be depicted and recognized as follows:

1.Where FEMA has designated a floodway for any river or stream on a FEMA Flood Insurance Rate Map (FIRM), the CRMC will recognize the same floodway; or

2.Where no FEMA floodway has been established for a river or stream, the edge of the channel as identified in § 9.21(A) of this Part shall also be considered the edge of the floodway.

9.21.5Criteria for Identification of Freshwater Wetlands for Farmers Conducting Normal Farming and Ranching Activities

A.For the purpose of R.I. Gen. Laws § 2-1-22 (k), identification of the edges of vegetated freshwater wetlands, flowing and standing water freshwater wetlands, and floodplains shall be consistent with the criteria specified in §§ 9.21.1, 9.21.2, and 9.21.3 of this Part, above.

B.The “area of land within fifty feet (50’)” shall be identified as the line measured landward horizontally, without regard for topography, fifty feet (50’) from the edge of any bog; marsh one (1) acre or greater; swamp three (3) acres or greater; or pond not less than one quarter (1/4) acre in size as those freshwater wetlands are defined herein.

C.The area of land within two hundred feet (200’) of a flowing body of water greater than or equal to ten feet (10’) wide and the area of land within one hundred feet (100’) of a flowing body of water less than ten feet (10’) wide shall be referred to as riverbank. The edge of riverbank along a river, stream, intermittent stream, or flowing body of water shall be determined by the method described herein:

1.The CRMC may compile designated riverbank widths (one hundred feet (100’) or two hundred feet (200’)) for flowing water body segments and maintain this information on file. Such designations shall be based upon currently available maps, aerial photographs, observations, and past determinations by the CRMC. All applicants may consult with the CRMC regarding the availability of designated riverbank widths along any flowing bodies of water segments in the project area. If a riverbank width has been determined by the CRMC, this designation can be used to preclude the need for the applicant to undertake field measurements or observations.

2.When designated riverbank widths are not available, the identification and assignment of a riverbank width shall, if the width is not obvious, be conducted using the following method, without regard to topography:

a.The width of the flowing body of water shall be measured along the channel’s length at a minimum of five (5) locations upstream and at a minimum of five (5) locations downstream from a measured midpoint within the project area or area of concern;

b.The measurements shall be taken at the midpoint, and at approximately equal intervals along the channel’s length with the minimum distance between intervals not less than twenty feet (20’) and the maximum distance between intervals not exceeding fifty feet (50’);

c.The midpoint of the measurements shall be near the midpoint of the project area or area of concern;

d.The measurements shall be taken between the edges of the flowing body of water or channel as delineated according to § 9.21.2(A)(1)(a) of this Part above; and

e.All measurements shall be taken at locations that are representative of the water body segment, must be documented as to the locations, and must be able to be reproduced. Measurements taken at any human-induced restrictions which are less than the natural conditions or within sections of the flowing body of water subject to unauthorized alterations are not applicable or acceptable.

3.The arithmetic average or mean of the channel width measurements shall serve as the average channel width for the purposes of assigning riverbank. The mean shall be calculated using the formula:

4.When the mean channel width is less than ten feet (10’), the riverbank shall be one hundred feet (100’). When the mean channel width is ten feet (10’) or more, the riverbank shall be two hundred feet (200’).

A.§ 9.23 of this Part presents the statewide buffer zones designated by the CRMC to protect freshwater wetlands, including rivers and ponds consistent with § 9.7 of this Part. The buffer zones are applicable to projects or activities that are subject to freshwater wetland permitting requirements except as otherwise provided for in §§ 9.5.7 and 9.13.1 through 9.13.4 of this Part, which governs freshwater wetlands for farmers, as defined in § 9.4(A) of this Part, conducting farming activities.

B.The designated buffer zones are organized into regions that are depicted on a map described in § 9.23(C) of this Part, below, and included in § 9.24 of this Part. The regions are:

1.Non-urban River Protection Region 1 and River Protection Region 2: These Regions include watershed areas that are high priorities for conservation of fish and wildlife habitat, including rivers which rank highest on a Rhode Island stream condition index, as well as areas of the State that exhibit a mix of land uses and watershed characteristics and settings.

2.Urban: This region includes densely developed areas of the State including portions of watersheds that contain high percentages of impervious cover and areas that are already developed or altered.

C.The freshwater wetlands buffer regions map prepared by the CRMC is adopted by reference with the promulgation of these Rules (§ 9.24 of this Part). The map shall be on file and made available for review at the CRMC. Additionally, the map information will be made available for viewing through the DEM’s website. The map should be used to identify the region within which a property is located and the buffer zone requirements that correspond to that region as specified within § 9.23 of this Part.

D.Buffer zone requirements applicable to public drinking water supply reservoirs and their watersheds are presented in §§ 9.23(H)(1), (2) and (8) of this Part, below.

E.The buffer zone requirements in each region are specified for various types of freshwater wetlands including ponds, vegetated freshwater wetlands, vernal pools, and rivers and streams. The following freshwater wetland subtypes are described below to guide their proper identification:

1.Wet meadow: A marsh that does not typically have standing water and is periodically grazed or mowed;

2.Phragmites marsh: A marsh whose plant community is composed of more than seventy-five percent (75%) non-native common reed (Phragmites australis);

3.Shrub swamp: A swamp or portion of a swamp whose plant community is composed of greater than fifty percent (50%) woody plants less than twenty feet (20’) tall;

4.Evergreen forested swamp: A swamp or portion of a swamp whose over story is composed of greater than fifty percent (50%) Atlantic white cedar (Chamaecyparis thyoides) or Eastern hemlock (Tsuga canadensis) trees;

5.Swamp with great-laurel Rhododendron: A swamp or portion of a swamp whose understory is composed of great-laurel Rhododendron (Rhododendron maximum) shrubs; and

6.For the purpose of identifying freshwater wetlands and their associated buffer zones, an emergent plant community shall be considered a marsh and a submergent plant community shall be considered a pond.

7.Fens are open canopy, groundwater-fed freshwater wetlands with less than fifty percent (50%) cover of trees. Shrubs are frequently present (less than fifty percent (50%) cover) as are grasses and mosses. The dominant plants are sedges.

8.Floodplain forests are hardwood swamps on lower terraces of river floodplains characterized by a flooding regime in which low areas are flooded annually, usually in the spring. In northern Rhode Island (along the Blackstone River and smaller rivers in Providence County) they are characterized by silver maple (Acer saccharinum) and sycamore (Platanus occidentalis) trees, while in southern Rhode Island (along the lower Pawcatuck River) they are characterized by red maple (Acer rubrum), pin oak (Quercus palustris) and green ash (Fraxinus pensylvanica) trees.

9.Freshwater pond shores that support coastal plain species are gently sloping sandy-gravelly shores of kettle ponds or pond depressions within Rhode Island’s coastal region. They may be seasonally or semi-permanently flooded, and they support distinct assemblages of grasses, sedges, rushes and other herbaceous plants.

F.Measurement of freshwater wetland buffer zones

1.The buffer zone shall be measured perpendicularly, without regard for topography, outward from the edge of the freshwater wetland as a horizontal distance. The freshwater wetland edge shall be determined consistent with § 9.21 of this Part.

2.The buffer zone associated with vegetated freshwater wetlands shall be designated based upon the wetland type or subtype identified at the edge in accordance with the Tables in § 9.23 of this Part. An additional twenty-five feet (25’) will be added to the buffer zone width when one (1) or more differing freshwater wetland types or subtypes are present within fifty feet (50’) inward of the freshwater wetland edge, but in no case will a buffer zone exceed the limit of a jurisdictional area. In large freshwater wetland systems, it is not necessary to map all of the interior wetland types.

3.For the purpose of designating a buffer zone, it may be necessary to determine the size of a freshwater wetland.

4.In the event that a property straddles a region boundary, a buffer zone width shall be designated consistent with the region within which its’ associated freshwater wetland is located.

5.In the event of the documented presence of a rare plant, rare animal, or rare freshwater wetland type, the CRMC reserves the right to increase the associated buffer zone width designated in §§ 9.23(H) or (I) of this Part.

G.Identifying the existing buffer within a buffer zone: On properties where a portion of the designated buffer zone has been developed or altered, the extent of existing undeveloped vegetated land shall include all areas adjacent to the freshwater wetlands that are not existing building, pavement, lawn or bare gravel.

H.Designated buffer zones in the non-urban River Protection Region 1 and River Protection Region 2

1.The following public drinking water supply reservoirs are designated a two hundred foot (200’) buffer zone:
