Service Area:
The umbrella service area is the area in which the Su Knik Mitigation Bank may potentially provide credits as compensatory mitigation to offset DA permitted impacts, as determined appropriate by the U.S. Army Corps of Engineers. For the Su Knik Mitigation Bank, the umbrella service area is the Matanuska Susitna Borough political boundary, and the area which resides outside of the Matanuska-Susitna Borough political boundaries but within the 6-digit HUC of 190205. For the 6-digit HUCs 190206 and 190204 there are properties that are within the Matanuska Susitna Borough boundaries that could be brought under the Su Knik Mitigation Bank Umbrella Agreement that would allow for these two six digit areas to become valid service areas.
Current Credits
For all sites currently approved (Big Lake South) and proposed (Big Lake West and Fish Creek West), the primary service area will be the 8-digit HUC 19020505, and the secondary service area will be the 6-digit HUC of 190205 in which the sites reside.
Primary Service Area
The primary service area is the designated geographic area wherein the Su Knik Mitigation Bank can reasonably be expected to provide appropriate compensation impacts to aquatic resources. For purposes of addressing Corps mitigation requirements the Su Knik Mitigation Bank's primary service area shall be considered before any other approved mitigation bank's or in-lieu fee program's secondary service areas, where appropriate credits are available.
Secondary Service Areas
The secondary service area is the designated geographic area wherein the Su Knik Mitigation Bank can reasonably be expected to provide appropriate compensation for impacts to aquatic resources. The secondary service area shall be considered for compensatory mitigation for any DA permit if: there are no available credits at any primary service area mitigation banks or in-lieu fee programs; and the applicant can demonstrate with supporting documentation that the credits in the secondary service area will compensate for the lost aquatic functions at the impact site.
