7h. Use the table below to list the type and rating of each wetland that will be impacted; the extent and duration of the impact; and the type and amount of mitigation you propose. If you are submitting a mitigation plan that includes a similar table, you may simply state (below) where we can find this information in the mitigation plan.

List the proposed activities causing impacts and mitigation for those impacts in the summary table. Include information on the activity causing impact (for example: excavation or fill), and wetland type separately for each wetland (based on the Western Washington/Eastern Washington wetland rating system). State how much area of each wetland (square feet or acres) will be impacted, duration of impact for each wetland (temporary or permanent), and what type of mitigation is proposed (for example: creation or restoration), and how many acres of mitigation will be provided.

 

If a table or chart containing this information is available by wetland in your mitigation plan, you can list the page number where the table or chart can be found.

 

Definition(s):

·         Wetland: An area that is inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances does support, a prevalence of vegetation adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas.

·         Impact:  For the purposes of this JARPA any activity in or adjacent to a wetland should be considered an impact; impacts may be temporary or permanent

·         Mitigation: Actions are taken to avoid, minimize, and compensate for adverse or negative effects on the environment.

·         Mitigation Bank: A mitigation bank is a wetland, stream, or other aquatic resource area that has been restored, established, enhanced, or (in certain circumstances) preserved for the purpose of providing compensation for unavoidable impacts to aquatic resources permitted under a federal, state or local regulation.  A mitigation bank may be created when a government agency, corporation, nonprofit organization, or other entity undertakes these activities under a formal agreement with a regulatory agency.

·         In Lieu Fee: An approach to compensatory mitigation that allows permit applicants to pay a fee to a third party such as a government agency or conservation organization. These fees are then used to restore, create, enhance, or preserve wetlands. Generally, in-lieu fee contributions are collected in advance of wetland losses. These funds are accumulated until they are sufficient to design and implement a wetland compensation project.

·         Creation: The manipulation of the physical, chemical, or biological characteristics present to develop a wetland on an upland or deepwater site where a wetland did not previously exist. Establishment results in a gain in wetland acreage and function.

·         Re-establishment: The manipulation of the physical, chemical, or biological characteristics of a site with the goal of returning natural or historic functions to a former wetland. Re-establishment results in rebuilding a former wetland and results in a gain in wetland acres and functions.

·         Rehabilitation: The manipulation of the physical, chemical, or biological characteristics of a site with the goal of repairing natural or historic functions and processes of a degraded wetland. Rehabilitation results in a gain in wetland function but does not result in a gain in wetland acres.

·         Enhancement: The manipulation of the physical, chemical, or biological characteristics of a wetland to heighten, intensify or improve specific function(s) or to change the growth stage or composition of the vegetation present. Enhancement is undertaken for specified purposes such as water quality improvement, flood water retention, or wildlife habitat. Enhancement results in a change in wetland function(s) and can lead to a decline in other wetland functions, but does not result in a gain in wetland acres.

·         Preservation: The removal of a threat to, or preventing the decline of, wetland conditions by an action in or near a wetland. This term includes the purchase of land or easements, repairing water control structures or fences, or structural protection. Preservation does not result in a gain of wetland acres but may result in a gain in functions over the long term.
