1. Excavation and deposition in a wetland is beneficial to wildlife. i.e. when done in <br />a low quality wetlands, such as one dominated by invasive species. <br />2. Deposition in a wetland is beneficial and creates diversity of wetland community <br />complimenting the existing ecosystem. <br />3. The spoil will form an island isolated from upland to prevent intrusion by people. <br />4. Excavations should have undulating bottoms and sinuous shorelines. <br />5. Depths shall be no greater than 6.5 feet from the original soil surface. <br />6. Side slopes should be no steeper than 5:1, but 10:1 or greater is recommended <br />7. Spoil placement not permitted in exemption, shall not be placed within any other <br />wetland. <br />8. Excavations for wildlife habitat improvement will be discouraged, or denied when <br />the wetland is already considered high quality, or the following conditions exist: <br />➢ Excavation in sedge meadow wetlands. <br />➢ Excavation in forested wetlands. <br />➢ Excavation in bogs. <br />➢ Excavations in wetlands identified as Natural Heritage Communities by the <br />Minnesota County Biological Survey. <br />➢ Excavations in wetlands deemed natural community, supporting <br />ecologically sensitive flora and fauna, based on field visit by the Soil and <br />Water Conservation District. <br />➢ The excavation will not provide diversity to the wetland basin or complex. <br />(e.g. excavation in the fringe of a type 3, 4 5 wetland with standing open <br />water throughout much of the growing season). <br />➢ Wetlands which support a wide variety of plant species (i.e. approximately <br />50% of the area supports species which individually comprise <5% of the <br />wetland). <br />➢ Wetlands that score high on the MNRAM vegetative diversity criteria. <br />➢ Excavations for the purpose of creating aesthetic reflecting pools. <br />The execution of the Wildlife Habitat Exemption is subject to approval by the ACD <br />Board. <br />Conservation Proiect Installation <br />ACD's program to assist with the cost of installing conservation practices to achieve the <br />goals of the district consists of several funding sources, each with their own set of <br />requirements. These funding sources change from year to year and so detailed <br />procedures and policies are not included in this document. There are, however, some <br />general policies that ACD has adopted to facilitate program administration and improve <br />program outcomes. <br />• The ACD board may act to obligate funds toward a project without fully <br />encumbering those funds within a contract. This serves to reserve funds for <br />projects while other elements of project planning, design and coordination can <br />be finalized. <br />• On a case by case basis, landowners/project sponsors/applicants may be <br />required to provide an escrow in the amount of anticipated design and <br />engineering costs. If the project construction bids come in within 10% of the <br />engineer's estimate and the applicant does not move forward with project <br />installation, the escrow may be used to reimburse ACD for the cost of the <br />page 46 Anoka Conservation District Comprehensive Plan October 2014 <br />
