    Sample Credit / Debit Calculation Worksheet for Mitigation Banks

    Development Acres

    This is the amount of acreage of a given natural resource type (e.g., frequent emergent wetland, wetgrass prairie, vernal pool, snowy plover breeding habitat, etc.) that will be converted to alternative uses (e.g., housing sub-divisions, shopping malls, highway interchanges, etc).

    Mitigation Acres

    This is the amount of acreage of a given parcel of land (often degraded farm land or open space) that will be converted to alternative uses (e.g., frequent emergent wetland, wetgrass prairie, vernal pool, snowy plover breeding habitat, etc.) to off-set the loss of the same or similar resources somewhere else.

    Development Multiplier

    This is an assigned number often representing the relative importance of a particular resource type. Resources assigned high importance values are assumed to require a proportionally greater number of acres to compensate for their loss. Factors that can affect the assignment of resource value include but are not limited to: 1) scarcity in the landscape relative to historical extent, 2) time periods required to reach a fully functioning condition, 3) importance to focal concerns (e.g., imperiled species, watershed TMDLs, aesthetic and recreational opportunity, 4) the relative capability of a habitat unit to provide life-cycle requirements for a species, etc.). The acreage of a given development site multiplied by its assigned development multiplier equals the amount of debit accrued by the development action and the amount of credit needed from the mitigation site to off-set the debit.

    If the development site is equal to 10-acres and the Development Multiplier is 2, then the number of debits is 20 (10 x 2).

    It should be noted here that mitigation "ratios" are often derived directly from ranking comparisons between development sites and compensatory mitigation sites.

    For example if the relative value of the development site is 3 and the relative value of the mitigation site is 2, then the ratio applied to the mitigation action is 3/2 or 1.5:1. Under this principle it is also possible (and hopefully probable) that the development site may be lower value than the mitigation site after the mitigation action is complete and meeting its performance objectives. For example, if the relative value of the development site is 2 and the relative value of the mitigation site is 3, then the ratio aplied to the mitigation action is 2/3 or 0.67:1. Since ratios of < 1 result in a net loss of natural resource acres, many regulatory agencies have taken the option of imposing a minimum compensatory mitigation ratio of 1 (also represented as 1:1).

    It is my intent that future versions of this web site will be connected to a relational database management system (RDMS), possibly Microsoft SQL Server, that will contain data, run queries, and generate reports that reflect known field conditions measured against both performance standard criteria and functional assessment criteria and which will in turn be used to inform compensatory mitigation ratios and to model compensatory mitigation outcomes.

    Mitigation Divider

    This is an assigned number often representing the relative likelihood of mitigation success depending on the compensatory mitigation method(s) employed. Methods that have a low track record of failure are generally assigned low mitigation dividers and those with a demonstrated high risk of failure are typically given higher mitigation dividers. Also compensatory mitigation methods that result in 100% loss of resource acreage are often assigned higher mitigation dividers. The acreage of a given mitigation site divided by its assigned mitigation divider equals the amount of credit available at that mitigation site.

    Mitigation Divider Values
    High: 4 Medium-High: 3 Medium: 2 Low: 1

    If the mitigation site is equal to 10-acres and the mitigation divider is 2, then the number of credits available is 5 (10 / 2).

    Price Per Credit

    The "price per credit" is generally a free-market determined decision often based on the sale prices of credits in the general area being "serviced" by a mitigation site. Factors such as the monetary cost of producing a credit (e.g., costs of land acquisition, site-preparation, maintenance, long-term endowments, etc.) combined with the prices of credits from competing mitigation providers have a relatively large influence on the price a credit is sold for. These prices tend to vary temporally and spatially depending on such factors as supply and demand, the strength of the economy, and proximity to major metropolitan areas.

    Service Area

    The geographic area (e.g., species recovery unit or watershed) surrounding a conservation or mitigation bank where species and/or regulated aquatic resource debits (i.e., development actions) may be accrued against the credits generated by the conservation or mitigation bank

    View Willamette Valley Mitigation Banks

    Note: A good way to use this web map application is to first make sure the area of interest is included in the extent (top to bottom and sides) of the map area you are viewing and that you have opened the attribute table (icon on the far left). Then click on the tab of the bank you are interested in and highlight it by clicking on the gray bar left of the far left column. Next, double click on the record to zoom into the bank boundaries. Repeat these steps for the service areas (SA) of the respective banks of interest. You may want to clear your selections before moving on to the next bank of interest. If you want to see where a proposed project is located in relation to a given bank and / or its Service Area, just type in the project address or coordinates in the serarch box and select the search icon. Be aware that attribute table records are only enabled if their related spatial data are inside the extent you are zoomed to in the map view window. No guarantee is given as to the accuracy or completeness of these data. The data are updated without notice on a periodic basis.
