WETLAND CONSERVATION PLAN
WETLAND RESOURCE DESIGNATIONS AND ANALYSIS OF ALTERNATIVES
(1) This rule applies to decisions concerning wetland resource designations and analysis of alternatives made after the local government sponsoring the Wetland Conservation Plan (WCP) has:
(a) Defined the WCP area;
(b) Completed the required Local Wetlands Inventory (LWI) according to the criteria of OAR 141-086-0180 to 141-086-0240;
(c) Completed the required wetland function and value assessments using an assessment methodology acceptable to the Division; and
(d) Developed WCP Goals for the planning area that consider the legislative findings in ORS 196.668.
(2) Consistent with ORS 527.722 of the Forest Practices Act, this rule does not apply to forest practices as defined in ORS 527.620 in areas regulated by the Forest Practices Act (ORS 527.610 to 527.770, 527.990(1) and 527.992).

(1) This rule:
(a) Identifies the procedures for local governments and the Director to use when analyzing alternatives to adversely impacting wetland systems;
(b) Provides criteria for local governments to use when designating wetlands or portions of wetlands within the WCP into Protection, Conservation or Development Categories; and
(c) Defines the minimum information required of local governments to allow the Director to develop findings of fact to determine whether practicable alternatives to adversely impacting wetlands or portions of wetlands designated into the Development Category are available. This information includes the determination of whether:
(A) A public need for the proposed use is, set forth in the acknowledged local comprehensive plan;
(B) Adverse impacts to wetland systems are avoided to the extent practicable; and
(C) The anticipated impacts of fill or removal on wetland systems are minimal.
(2) This rule is not meant to establish the definitive analysis for every aspect of wetland conservation planning. In addition to meeting the requirements of this rule, each jurisdiction must also comply with all parts of ORS 196.668 to 196.692 and with its own and other relevant ordinances and state and federal laws, including Section 404 of the Clean Water Act.
The Division shall adhere to the following policies when providing technical assistance to local governments developing a WCP and when reviewing a WCP proposed for the Director's approval:
(1) Wetland systems are important ecological components of the landscape and provide numerous functions and values;
(2) The Division shall ensure that full replacement of wetland functions and values, lost under the authority of OAR 141-120-0000 to 141-120-0230, occurs and that a stable resource base is maintained;
(3) Local governments have the authority to establish and, as necessary, adjust the Urban Growth Boundary (UGB) and the Division shall accept decisions, acknowledged by the Land Conservation and Development Commission or by operation of law, that relate to setting or adjusting the UGB or the boundaries of an Urban Service Area or Exception Area;
(4) The state shall promote the protection, conservation and best use of wetland resources and their functions and values through the integration and close coordination of state-wide planning goals, local comprehensive plans and state and federal regulatory programs (ORS 196.672(1));
(5) Because WCPs are meant to resolve conflicts between the protection and conservation of wetlands and the use of wetlands for development, the WCP area shall include undeveloped land with development conflicts involving wetlands;
(6) The Division shall not approve a WCP that merely attempts to obtain state authorization for individual development projects including those that cover large areas, are multi-phased or are controlled by a single ownership or management entity;
(7) Wetlands designated in the Protection Category and those used for compensatory mitigation under a WCP shall be protected in perpetuity. A protection designation may only change as a result of a plan amendment (ORS 196.684), if, after opportunity for public comment, the Director finds that a substantial change in circumstance has occurred; and
(8) For the purpose of this rule, the determination of whether a wetland provides a function or value, has potential to provide a function or value, does not provide a function or has enhancement potential will be made according to the Oregon Freshwater Wetland Assessment Methodology unless the local jurisdiction has obtained written approval from the Division to use a different assessment methodology. If a different assessment methodology is approved then equivalent terminology will be set out in the Division's letter of approval.
For purpose of this rule, all definitions in OAR 141-120-0005 are also applicable.

(a) Planned infrastructure as authorized in OAR 141-120-0180, and
(b) Construction of committed infrastructure.
The Purpose of the Development Category
The purpose of placing wetlands or portions of wetlands into the Development Category is to help balance the public's need for development with the need to protect and conserve important wetland resources.
Management Directive for the Development Category
(1) To offset the adverse impacts of allowing wetlands to be used for development, the associated mitigation plan for the WCP shall ensure full replacement of wetland functions and values and shall maintain a stable resource base.
(2) Until development projects are reviewed and authorized in accordance with the WCP or the Director's order approving the WCP, local governments shall ensure that areas in the Development Category are managed according to OAR 141-120-0100.

(b) The functions and values assessment for the wetland indicates that the wetland:
(A) Provides no function and has little enhancement potential; or
(B) Provides or has potential to provide only functions or values that are not listed as WCP Goals and has little enhancement potential.
(3) A local government may designate wetlands or portions of wetlands notwithstanding the wetland's size or connectivity into the Development Category if:
(a) The functions and values assessment for the wetland indicates that the wetland provides or has potential to provide a function or value that is listed as a WCP Goal or has enhancement potential; and
(b) The local government:
(A) Determines that there is no less damaging practicable alternative with the same comprehensive plan land use designation within the UGB, the Urban Service area or the Rural Service area; and
(B) Provides an explanation, in the form of a finding of fact with supporting reasons, as to why the comprehensive plan's land use designation cannot be changed to avoid impacting the wetland.
(4) For the purposes of OAR 141-120-0160, the term "less damaging practicable alternative" means "less environmentally damaging practicable alternative".
Uses Allowed in Development Category Wetlands
A local government may allow the following uses after reviewing the proposed use against criteria and standards set out in the WCP implementing ordinances, that ensure that the uses meet the management directives in OAR 141-120-0150 and are intended to achieve WCP Goals:
(1) All uses allowed in the WCP and implementing zoning ordinances;
(2) Construction of committed infrastructure; and
(3) Biofiltration or other wetland water treatment systems provided the proposed project meets all applicable water quality standards.

(A) Existing development is dependent on the planned infrastructure; or
(B) The planned infrastructure is required to allow access to buildable uplands;
(b) Provides a showing of actions considered and taken to avoid and minimize impacts to the wetland system in the planning area; and
