If filtration areas are being used astemporary sediment basins during construction, leave a minimumof 1 feet of cover over the practice to protect the underlying soilsfrom clogging.6.Complete, stabilize, and vegetate all other site improvements.7.Construct and vegetate basin following stabilization of contributingdrainage area. Ensure that critical elevations, such as underdraininvert, top of media, top of mulch, and invert of overflow structure(if present) are correct.8.Remove temporary erosion control devices after the contributingdrainage area is adequately vegetated.CLEANOUT (TYPICAL)12FILTRATION SECTION(SHALL ADHERE TO MPCA MN STORMWATER GUIDELINES)3" MULCH30" FILTRATION MEDIA(MIX C SUITABLE FOR FILTRATION W/UNDERRAIN)3" CLEAN EMBEDMENT STONE COVER (#57 STONE)6" PERFORATED HDPE OR PVC UNDERDRAIN3" CLEAN EMBEDMENT STONE BEDDING (#57 STONE)TOTAL FILTRATION SECTION DEPTH = 3.75'WATER QUALITY VOLUME (WQV) ELEVATIONTOTAL STORAGE VOLUME ELEVATION994.50991.00989.00985.50TOP OF BASIN BERM995.00EMERGENCY SPILLWAYWQV ELEV.BOTTOM OF BASINUNDERDRAIN OUTLET INV.3.50'2.00'3.50'2=/>3.00'SEPARATION TO BEDROCK OR GROUNDWATER3NON-COMPACTED SUBGRADE (SEE STORMWATER MANUAL FOR SUBGRADE PREP.)3FILTRATION BASIN GENERAL NOTES1.In the event that sediment is introduced into the basin during orimmediately following excavation, this material shall be removedfrom the basin prior to continuing construction.2.See Minnesota Stormwater Manual for material specificationsrecommendations for filtration soil mixes, mulch, etc.3.Design is based on the WQV draining within 48 hours maximum.MAX. 3L:1H SLOPEFILTRATION BASIN WITH UNDERDRAINNOT TO SCALE DescriptionRev.DateMINNEWASHTA APARTMENTS CHANHASSEN, MINNESOTA07.11.2025CITY SUBMITTALSheet Title:Project #:Drawn By:Checked By:Issue Date:25-102PMJM06/13/2025G:\Shared Drives\Active Projects\Chanhassen\Headwaters Dev - Minnewashta MF\CAD\Sheets\CIVIL DETAILS.dwgProject Title: HEADWATERS 6757 KARMEN AVENUE ALBERTVILLE, MN Client:Date: Lic.
