<br />IF YES, INDICATE THE CURRENT AND PROJECTED WATERCRAFT USAGE AND <br />DISCUSS ANY POTENTIAL OVERCROWDING OR CONFLICTS WITH OTHER <br />USERS OR FISH AND WILDLIFE RESOURCES. <br />AUAR: <br />This item need only be addressed if the AUAR area would include or adjoin recreational <br />water bodies. <br /> <br />. <br /> <br />Not Applicable. <br /> <br />16. EROSION AND SEDIMENTATION <br /> <br />EAW: <br />GIVE THE ACREAGE TO BE GRADED OR EXCA V A TED AND THE CUBIC YARDS <br />OF SOIL TO BE MOVED: ACRES ; CUBIC YARDS , DESCRIBE <br />ANY STEEP SLOPES OR HIGHLY ERODIBLE SOILS AND IDENTIFY THEM ON <br />THE SITE MAP. DESCRIBE ANY EROSION AND SEDIMENTATION CONTROL <br />MEASURES TO BE USED DURING AND AFTER PROJECT CONSTRUCTION. <br /> <br />AUAR: <br />The number of acres to be graded and the number of cubic yards of soils to be moved need <br />not be given; instead, a general discussion of the likely earthmoving needs for development <br />of the area should be given, with an emphasis on unusual or problem areas. In discussing . <br />mitigation measures, both the standard requirements of the local ordinances and any <br />special measures that would be added for A UAR purposes should be included. <br /> <br />While it is premature to determine the detailed earthmoving requirements for the future <br />development phases, because the redevelopment sites are relatively flat and most areas <br />have been previously developed, unique and/or unusual earthwork requirements for the <br />proposed redevelopment are not anticipated. <br /> <br />The potential for erosion and sedimentation of soils exposed during redevelopment of the <br />AUAR study area will be minimized by using Best Management Practices (BMPs) during <br />and after construction. Erosion control practices will be identified in the final site grading <br />and construction plans as required by the NPDES permit and in accordance with the City of <br />Arden Hills and Rice Creek Watershed District's erosion/sedimentation control standards. <br /> <br />All erosion control measures shall be installed prior to grading operations and maintained <br />until all disturbed areas have been restored. Streets will be swept as necessary where <br />construction sediment has been deposited, Also, NURP ponds must be constructed before <br />main grading. After construction, all disturbed arcas will be either paved or vegetated to <br />eliminate exposed soil surfaces. Removal of erosion control measures will not occur until <br />all disturbed areas have been stabilized. <br /> <br />. <br /> <br />Guidant Campus Master Plan <br />Draft AUAR <br /> <br />.19- <br /> <br />September 2002 <br />
