Rhode Island Code of Regulations, Part 2, Section 650-RICR-20-00-2.10 - Application to Alter a Freshwater Wetland (formerly Section 10.00) | Rhode Island Code of Regulations

A. Purpose (formerly §10.01)

1. In accordance with R.I. Gen. Laws § 2-1-22(a), an application to alter a freshwater wetland will be required if a significant alteration is proposed. Such an application is subject to the application procedures and requirements as set forth in R.I. Gen. Laws § 2-1-22 and these Rules.

2. A significant alteration results from a project that:

a. Because of its area, scope or duration, appears to represent more than a minimal change in or modification to the natural characteristics, functions or values of any freshwater wetland;

b. May be detrimental to the basic natural capabilities or values associated with such freshwater wetland; or

c. Appears to be random, unnecessary or undesirable.

3. Prior to filing an application to alter, an applicant may file a request for preliminary determination to determine whether or not a project appears to represent a significant alteration to freshwater wetlands. The CRMC recommends that an applicant file a request for preliminary determination prior to filing an application to alter, unless the applicant is confident that the project represents a significant alteration to freshwater wetlands.

B. Application requirements (formerly §10.02). An applicant seeking a permit for a significant alteration through an application to alter a freshwater wetland must adhere to the following requirements and submit all written evaluations and documentation as set forth in § 2.10(B)(3) of this Part.

1. Project scope. An application to alter a freshwater wetland must include and describe the entire project proposed or contemplated by the applicant. A request for a partial review or a review of fewer than all phases of a project may be considered by the CRMC only if:

a. The CRMC has previously reviewed the entire project and considered all project impacts on freshwater wetlands; or

b. As a condition of a prior determination, permit, or consent agreement, or consent judgment, the CRMC required separate applications for individual portions of an overall project.

2. General provisions. A completed application to alter must comply with the general provisions set forth in § 2.7 of this Part as well as the following specific requirements:

a. An original completed application form (See § 2.7(A) of this Part);

b. Site plans which accurately and clearly depict the project and provide, in the opinion of the CRMC, the correct location, extent, and type of all wetlands within and near the project (§§ 2.7(C) and (D) of this Part);

c. A fee (§§ 2.7(J) and (K) of this part);

d. Proof of ownership in the form of a current certified copy of the deed of the subject property;

e. A current list of the property owners whose properties abut the proposed project parcel(s) as required by Part 10-00-1.5 of this Title (CRMC Management Procedures). This list of property owners must contain the current mailing address of each property owner and must be accompanied by a map drawn to scale of not less than one inch to one hundred feet (1"=100') showing the properties, lot numbers, and corresponding owners immediately abutting the parcel(s) of the proposed wetland alteration(s). For the purposes of determining the abutting property owners to the proposed project, the applicant shall measure from the outermost boundaries of the proposed wetland alterations. Such wetland alteration boundaries must include at least the following:

(1) The extent of all physical disturbance in regulated wetlands;

(2) The extent of any impoundment or raising of water elevations in wetlands;

(3) The extent of drainage of wetlands, including lowering of surface and sub-surface water elevations;

(4) The relocation of flowing bodies of water or watercourse s, including the original and proposed locations; and

(5) The expansion of any regulated wetland areas into adjacent properties.

f. All written evaluations and documentation as set forth in § 2.10(B)(3) of this Part;

g. Following notification from the CRMC, the required number of full-size and reduced site plans, drawn to scale and legible, which are necessary to provide to the municipality, the abutters, and other interested parties;

h. Completed field work that includes field reference markers on the property and points on the site plans sufficient to outline the limits of the project and to identify the edge of all wetlands within the project in a manner sufficient for the CRMC to properly complete its evaluation.

3. Written documentation and evaluation. All applicants must provide a written evaluation including a table of contents, a project description, an avoidance and minimization statement, and an evaluation of the wetland functions, values and impacts:

a. The table of contents shall list all section titles and their corresponding page numbers.

b. The project description shall describe the overall project, including the project size, purpose, location, and type; site history; and overall areas evaluated including nearby roadways and adjacent land uses.

d. The evaluation of functions, values, and impacts must describe the evaluation methodology, qualifications of professional(s) performing the evaluation; identification of regulated freshwater wetlands; description of wetland functions, values, and impacts, identification of the proposed measures to reduce such impacts; conclusions; and any literature citations as set forth in § 2.10(B)(5) of this Part below.

4. Avoidance and minimization requirement

a. Avoidance: All persons must satisfactorily demonstrate to the CRMC in the form of a written narrative that all probable impacts to freshwater wetlands 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. 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 as a central element of its primary purpose (e.g., a pier);

(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;

(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 wetland 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 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 wetlands;

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

(6) Whether feasible alternatives that would not alter the natural character of any freshwater wetlands 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 that cannot be avoided, the applicant must satisfactorily demonstrate to the CRMC in the written narrative that the impact to wetland 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 purpose;

(2) Whether the proposed project is necessary at the proposed location or whether another location within the site could achieve the project purpose while resulting in less impact to the wetland;

(3) Whether there are feasible alternative designs, layouts, densities or technologies, that would result in less impact to the wetland while still achieving the project purpose; and

(4) Whether reduction in the scale or relocation of the proposed project to minimize impact to the wetland would result in adverse consequences to public health, safety or the environment.

c. Mitigation measures: Measures, methods, or best management practices to avoid alterations of and minimize impacts to wetlands are described in § 2.9(B)(1)(d) ((3)) of this part.

5. Evaluation of wetland functions, values, and impacts. All applicants must describe those functions and values provided and maintained by the subject freshwater wetland; describe and assess any anticipated impacts to the wetland's functions and values; and describe all structural or non-structural best management practices, best available technologies, schedules, and management plans which will be employed to avoid, or minimize impacts to freshwater wetlands to the maximum extent possible. This written evaluation must clearly and fully explain how the proposed project complies with the applicable review criteria set forth or referred to in § 2.10(E) of this Part and must describe the evaluation methodology, the qualifications of persons involved in the evaluation, and must describe all freshwater wetlands.

a. Evaluation methodology: Identify the scientific techniques and methods which were used to complete the evaluation, including the dates and times of observations and field studies and the result of such observations and field studies. Identify each specific evaluation methodology that was used, and identify, describe, and explain any deviation from the methodology, and any assumptions made with a specific methodology. Identify and describe any limitation placed upon the study or evaluation which could affect the outcome of the results.

b. Qualifications: List the names and qualifications of each person involved in the evaluation. Assessment of wetland functions and values and impacts may require input by more than one qualified professional consultant or more than one individual familiar with the specific functions or values of the wetland. The names, addresses and backgrounds of any individuals consulted for the evaluation must be submitted as well as a description of the extent of their participation.

c. Freshwater wetlands: Describe all freshwater wetlands on-site as well as any off-site wetlands that are hydrologically connected to the on-site wetland(s) and identify all wetlands evaluated, including any areas of potential impact associated with the project within freshwater wetlands.
