CC Regular Session Meeting Date: 07/24/2012 By: Kathy Schmitz, Administrative Services Information 4. 9. Title: Request for an Interim Use Permit for Grading and Mining Activities on Outlots A & B Elmcrest Sanctuary; Case of Oakwood Land Development Inc. Background: The City has received an application from Oakwood Land Development, Inc. for an Interim Use Permit (IUP) for grading and mining activities on Outlots A & B Elmcrest Sanctuary. The Applicant is requesting the IUP to export approximately 60,000 cubic yards of soil to create a wetland on these parcels for the purposes of a wetland mitigation bank. Per City Code Section 117-359, all excavations in excess of 400 cubic yards of material require an interim use permit. Notification: All property owners within 350 feet of the Subject Property were notified of the Public Hearing via Standard US Mail. A Notice of Public Hearing was also published in the Anoka County Union. Observations: The purpose of creating the wetland is to establish a wetland mitigation bank. A wetland 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 Section 404 or a similar state or local wetland 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 this case the Lower Rum River Watershed Management Organization (LRRWMO), under the requirements of the Wetland Conservation Act (WCA). The Applicant proposes to create the wetland by excavating upland area down to water depths of six (6) feet or less and then re -vegetate the created wetland and adjacent upland with native herbaceous species. The area to be graded is approximately eleven (11) acres. The subject property seems to be an ideal site for a wetland bank due to its challenging development potential. The wetland bank would provide the property owner with some monetary return on the property. The Applicant is proposing to complete the project in a single phase. The grading is anticipated to be completed within three (3) months, with the restoration (plantings) completed as areas are final graded. Through the wetland bank procedure requirements, maintenance and monitoring is required for a period of five (5) years after project completion. This monitoring will be completed by the LRRWMO. Due to this, Staff does not see any reason to require a landscape surety/guarantee; however, the IUP will be conditioned upon collection of an erosion control escrow of $1,500 (per the standard rates and charges). The Applicant provided plans for dust and noise control during excavating activities. Plans call for watering and sweeping of roads as needed to minimize dust. Any associated noise will be from the excavating equipment and trucks hauling soil away. Existing single family residences are located southwest, west and north of the subject property. Due to the proximity to existing residential homes, the IUP stipulates that the grading/excavating activities be limited to 7:00am and 7:00pm Monday through Friday and 8:00am to 7:00pm on Saturdays. The Applicant has indicated that the project is currently under review by other agencies, as required by the WCA, and that that review process is taking longer than initially anticipated. The Applicant is hopefull that the wetland bank plan will receive approval from the LRRWMO in August or September of 2012. City Engineering Staff reviewed the application and provided comments to the LRRWMO expressing support for the proposed wetland bank, with a request for some revisions to address potential overflow issues north of 167th Avenue.
