BACKGROUND/JUSTIFICATION:
Darkenwald Holdings, LLC has submitted plans for grading work to be undertaken on property located at 15815 70th
Street, south of the 70th Street (CSAH 38) and Quaday Avenue intersection. The grading work involves approximately 10
acres of the subject site and will include removal of material from the property in preparation for eventual development.
The extent of the work is limited at this time to the corridor for future extension of Quaday Avenue south of 70th Street
(CSAH 38) to the east property line.
The proposed grading is not defined as gravel mining under the Zoning Ordinance. Section 11-24-1 of the Zoning
Ordinance requires approval of a Grading Permit for excavations not defined as mining but also not occurring as part of
an approved development plan or subdivision. Applications for Grading Permits are subject to review by the City
Engineer and approval of the City Council.
The City Engineer has approved the proposed grading plans. The developer will be required to enter into an
administrative grading agreement with the City and provide a security of $3,000.00 per disturbed acre.

SeeErosion Control sheets for the location and type of permanent erosion prevention and sediment control BMPs.Minimize Disturbed Areas and Protect Natural Features and SoilAppropriate construction practices (e.g. construction phasing, vegetative buffer strips, horizontal slope grading) shall be used tominimize erosion.Areas not to be disturbed (buffers, infiltration basins, etc.) shall be protected with construction or silt fence before work begins.Operator shall develop methods to minimize soil compaction outside of building pads, pavement areas and utility trenches and shalluse tracked equipment wherever practicable.Topsoil shall be salvaged and reused to the extent practicable.Phase Construction ActivityOperator must not disturb more land than can be effectively inspected and maintained.Sediment control practices shall be established on all down gradient perimeters before any upgradient land disturbing activities begin.These practices shall remain in place until final stabilization has been established in accordance with the Permit.The timing of the installation of sediment control practices may be adjusted to accommodate short-term activities such as clearing orgrubbing, or passage of vehicles. Any short-term activity must be completed as quickly as possible and the sediment controlpractices shall be installed immediately after the activity is completed. However, sediment control practices shall be installed beforethe next precipitation event even if the activity is not complete.Control Stormwater Flowing onto and Through the ProjectThe normal wetted perimeter of any temporary or permanent drainage ditch or swale that drains water from any portion of theconstruction site, or diverts water around the site, shall be stabilized within 200 lineal feet from the property edge, or from the point ofdischarge into any surface water.Stabilization of the last 200 lineal feet shall be completed within 24 hours after connecting to a surface water.Stabilization of the remaining portions of any temporary or permanent ditches or swales shall be complete within 14 days afterconnecting to a surface water and construction in that portion of the ditch has temporarily or permanently ceased.Temporary or permanent ditches or swales that are being used as a sediment containment system (with properly designed rock ditchchecks, bio rolls, silt dikes etc.) do not need to be stabilized. These areas shall be stabilized within 24 hours after no longer beingused as a sediment containment system.Stabilize SoilsAll exposed soil areas, including stockpiles, must be stabilized.Stabilization must be started immediately to limit soil erosion when the construction activity in that portion of the site has temporarilyor permanently ceased and will not resume for 14 calendar days.
