430.200 Natural Resource Management Plans | Wood Village Development Code

430.200 Natural Resource Management Plans.

Prior to issuing any permits in a WQRA a Natural Resource Management Plan must be submitted to the City as follows:

Natural Resource Management Plans or restoration plans that authorize limited disturbance within the WQR or HCA may be approved with a Type I or II review, subject to the following standards:

A. Plans Eligible for Type I Review. The plan has already been approved by the U.S. Fish and Wildlife Service, Oregon Department of Fish and Wildlife (ODFW), DSL, Oregon Watershed Enhancement Board (OWEB), Metro, East Multnomah County Soil and Water Conservation District, or other agency approved by the City Administrator.

B. Plans Eligible for Type II Review. The plan has been prepared in accordance with particular standards and guidelines promulgated by a natural resource agency, such as OWEB’s Oregon Aquatic Habitat Restoration and Enhancement Guide, ODFW’s Western Oregon Stream Restoration Program, DSL’s Hydrogeomorphic (HGM) approach of assessment for wetland and riparian functions, or other standards approved by the City Administrator.

C. Approval Criteria. Every plan prepared for approval in this Section shall demonstrate that it encourages restoration activities that have any of the following effects:

(1) Changes the trend of habitat function from one of a diminishing ability to support salmonids and other organisms to one that supports a complex, self-sustaining system.

(2) Corrects or improves conditions caused by past management and/or disturbance events.

(3) Maximizes beneficial habitat in the short term where watershed degradation has been extensive and natural processes will need substantial time to restore habitat.

(4) Creates beneficial habitat and restores stream function and hydrology to the fullest extent practicable within developed areas where there is no reasonable expectation of returning to natural conditions.

D. Construction Management Plans. A Construction Management Plan (Section 430.190) is required with each Natural Resource Management Plan.

E. Ongoing Maintenance. Natural Resource Management Plans shall demonstrate how ongoing maintenance is part of the associated restoration or enhancement activities.

F. Expiration of Plans. The approval of a Natural Resource Management Plan shall be valid for 5 years. Approved plans may be renewed through the Type I review process by demonstrating that the original approved plan still meets the criteria provided in this Section. Plans that demonstrate an adaptive management component and/or that involve partnership with one of the agencies noted in this Section may be approved as valid for up to 20 years upon request.

Table 2. Water Quality Resource Area Determination Of Condition and Requirements
Existing Condition of Water Quality Resource Area	Requirements if Water Quality Resource Area Remains Undisturbed During Construction	Requirements if Water Quality Resource Area is Disturbed During Construction
Good Existing Corridor: Combination of trees, shrubs and ground cover are 80% present, and there is more than 50% tree canopy coverage in the vegetated corridor.	Provide certification by registered professional engineer, landscape architect, or biologist or other person trained or certified in riparian or wetland delineation that vegetated corridor meets the standards of this ordinance. Inventory and remove debris and noxious materials.	Prior to construction, a biologist or landscape architect shall prepare and submit an inventory of vegetation in areas proposed to be disturbed and a plan for mitigating water quality impacts related to the development, including: Sediments, temperature and nutrients, sediment control, temperature control, or addressing any other condition that may have caused the Protected Water Feature to be listed on DEQ’s 303 (d) list. Inventory and remove debris and noxious materials.
Marginal Existing Vegetated Corridor: Combination of trees, shrubs and groundcover are 80% present, and 25-50% canopy coverage in the vegetated corridor.	Provide certification by registered professional engineer, landscape architect, or biologist or other person trained or certified in riparian or wetland delineation that vegetated corridor meets the standards of this ordinance. Inventory and remove debris and noxious materials.	Vegetate disturbed and bare areas with, non-nuisance plantings from the City Plant List. Inventory and remove debris and noxious materials. Revegetate with native species using a City/County approved plan developed to represent the vegetative composition that would naturally occur on the site. Seeding may be required prior to establishing plants for site stabilization. Revegetation must occur during the next planting season following site disturbance. Annual replacement of plants that do not survive is required until vegetation representative of natural conditions is established on the site. Restore and mitigate according to approved plan using non-nuisance plantings from the City Plant List. Inventory and remove debris noxious materials.
Degraded Existing Vegetated Corridor: Combination of trees, shrubs, and ground cover are less than 80% present and/or less than 25% canopy coverage in vegetated corridor.	Vegetate bare areas with plantings from approved Native Plant List. Remove non-native species and revegetate with plantings from approved Native Plants List. Inventory and remove debris and noxious materials.	Vegetate disturbed and bare areas with appropriate plants from the City Plant List. Remove non-native species and revegetate with non-nuisance plantings from the City Plant List. Plant and seed to provide 100 percent coverage. Restore and mitigate according to approved plan using non-nuisance plantings from the City Plant List. Inventory and remove debris and noxious materials.
