ANTICIPATED APPROXIMATE TIMELINES: ESTIMATED PROJECT START DATE: 04/01/17 ESTIMATED PROJECT COMPLETION DATE: 11/30/19 i.a SOILS, SLOPES, VEGETATION, AND CURRENT DRAINAGE PATTERNS SOILTYPEIS): SOILS ON SITE PRIMARILY CONSIST OF LOAMY SOILS INCLUDING LESTER, CORDOVA, SUCKERCREEK AND ANGUS LOAM. SOILS ARE OF HYDROLOGIC SOIL GROUP D. SLOPES THE SITE HAS BEEN PREVIOUSLY ROUGH GRADED AND EXISTING SLOPES RANGE FROM 1-2% IN THE FLAT AREAS OFTHE ROAD WAY TO UP TO 33% ACROSS THE PREVIOUSLY ESTABLISHED LOTS. GRADES ON SITE WILL REMAIN LARGELY THE SAME EXCEPT FOR THE ROAD AREAS WHICH WILL BE FINISH GRADED WITH THE ESTABLISHMENT OF THE ROAD. DRAINAGE PATTERNS: EXISTING DRAINAGE PATTERNS ON SITE ARE SUCH THAT WATER PRIMARILY DRAINS CENTER-0UT, WITH WATER EVENTUALLY ENTERING A ONE OFTHE STORMVIATER PONDS SURROUNDING THE SITE. THESE DRAINAGE PATTERS WILL BE MAINTAINED AFTER CONSTRUCTION IS COMPLETE. VEGETATION: THE SITE AS IT CURRENTLY EXISTS IS COVERED IN ROUGH GRASSY VEGEGATION. THIS EXISTING VEGETATION ON SITE WILL LARGELY BE MAINTAINED, WITH THE EXCEPTION OF THE AREAS UNDERNEATH THE NEWLY ESTABLISHED ROADWAYS. RAINFALLINFORMATION: RAINFALL INFORMATION -THE AVERAGE TOTAL ANNUAL PRECIPITATION 15 ABOUT 28.32 INCHES. OF THIS ABOUT 17.31 INCHES, OR 61 PERCENT, USUALLY FALLS IN MAY THROUGH SEPTEMBER.

THE UNNAMED CREEK THAT THE SITE DRAINS TO IS CONSIDERED IMPAIRED FOR AQUATIC MACROINVERTEBRATE BIOASSESSMENTS; FISHES RIOASSESSMENTS.

IN THE NATURAL CONDITION, SOIL IS STABILIZED BY NATIVE VEGETATION. THE PRIMARY TECHNIQUE TO BE USED ATTHIS PROJECT FOR FINAL STABILIZATION OF SITE SOIL WILL BE TO PROVIDE A PROTECTIVE COVER OF VEGETATION, PAVEMENT, OR BUILDING. ALL EXPOSED AREAS MUST BE STABILIZED AS SOON AS POSSIBLE (BUT NO LATER THAN THE NEXT WORKDAY) TO LIMITSOIL EROSION, BUT IN N'0 CASE LATER THAN 7 DAYS AFTER THE CONSTRUCTION ACTIVITY IN THAT PORTION OF THE SITE HAS TEMPORARILY OR PERMANENTLY CEASED. TEMPORARY SOIL STOCKPILES WITHOUT SIGNIFICANT SILT, CLAY OR ORGANIC COMPONENTS (E.G. CLEAN AGGREGATED STOCKPILES, DEMOLITION CONCRETE STOCKPILES, SAND STOCKPILES) AND THE CONSTRUCTED BASE COMPONENTS OF ROADS, PARKING LOTS AND SIMILAR SURFACES ARE EXEMPT FROM THIS REQUIREMENT, BUT MUST COMPLY WITH SECTION 2.7 OF THIS SWPPP (PART IV.CS OF THE GENERAL PERMIT). SEDIMENT CONTROL BMPS: THE PURPOSE OF SEDIMENT CONTROL IS TO PREVENT SOIL PARTICLES THAT HAVE BEEN SUSPENDED IN WATER FROM ENTERING SURFACE WATERS, INCLUDING CURB AND GUTTER SYSTEMS AND STORM SEWER INLETS, SEDIMENT CONTROL BMPS HAVE BEEN DESIGNED AS PART OF THIS SWPPP. IF THE DOWN GRADIENT TREATMENT SYSTEM IS OVERLOADED, THE CONTRACTOR 15 RESPONSIBLE FOR IMPLEMENTING ADDITIONAL UP GRADIENT SEDIMENT CONTROL PRACTICES OR REDUNDANT BMPS TO ELIMINATE THE OVERLOADING AND MUST AMEND THE SW PPP TO IDENTIFY THE ADDITIONAL PRACTICES. SEDIMENT CONTROL PRACTICES MUST ALWAYS BE ESTABUSHED ON ALL DOWN GRADIENT PERIMETERS AND BE LOCATED UPGRADIENT OF ANY BUFFER ZONES. THE PERIMETER SEDIMENT CONTROL PRACTICES MUST BE IN PLACE BEFORE ANY UP GRADIENT LAND DISTURBING ACTIVITIES BEGIN. THESE PRACTICES MUST REMAIN IN PLACE UNTIL FINAL STABILIZATION IS ACHIEVED (SEE SECTION 8 OF THIS SW PPP). THE TIMING OF THE INSTALLATION OF SEDIMENT CONTROL PRACTICES MAYBE ADJUSTED TO ACCOMMODATE SHORT-TERM ACTIVITIES SUCH AS CLEARING OR GRUBBING, OR PASSAGE OF VEHICLES. ANY SHORT TERM ACTIVITY MUST BE COMPLETED AS QUICKLY AS POSSIBLE AND THE SEDIMENT CONTROL PRACTICES MUST BE RE -INSTALLED IMMEDIATELY AFTER THE ACTIVITY IS COMPLETED. SEDIMENT CONTROL PRACTICES MUST REINSTALLED BEFORE THE NEXT RAIN EVENT EVEN IF THE ACTIVITY IS NOT COMPLETE. 2.1 MINIMIZE DISTURBED AREA AND PROTECT NATURAL FEATURES AND SOIL CARE IS TO BETAKEN TO NOT DISTURB MORE THAN WHAT 15 NECESSARY FOR THE CONSTRUCTION OFTHE PROJECT.

PREVIOUSLY EXISTING PERMANENT SEDIMENTATION BASINS THAT ARE TO BE USED AS PERMANENT WATER QUALITY MANAGEMENT BASINS HAVE BEEN CLEAN OF ANY ACCUMULATED SEDIMENT. ALL SEDIMENT HAS BEEN REMOVED FROM CONVEYANCE SYSTEMS AND DITCHES ARE STABILIZED WITH PERMANENT COVER. 3.ALLTEMPORARY EROSION PREVENTION AND SEDIMENT CONTROL BMPS MUST BE REMOVED. ,.FOR CONSTRUCTION PROJECTS ON LAND USED FOR AGRICULTURAL PURPOSES FINAL STABILIZATION MAY BE ACCOMPLISHED BY RETURNING THE DISTURBED LAND TO ITS PR CONSTRUCTION AGRICULTURAL USE. 5. FOR RESIDENTIAL CONSTRUCTION ONLY, INDIVIDUAL LOTS ARE CONSIDERED FINALLY STABILIZED IF THE 5TRUCrURE(S) ARE FINISHED AND TEMPORARY EROSION PROTECTION AND DOWNGRADIENT PERIMETER CONTROL HAS BEEN COMPLETED AND THE RESIDENCE HAS BEEN SOLD TO THE HOMEOWNER. ADDITIONALLY, THE PERMITTEE HAS DISTRIBUTED THE MPCA'S `HOMEOWNER FACT SHEET' TO THE HOMEOWNER TO INFORM THE HOMEOWNER OF THE NEED FOR, AND BENEFITS OF, PERMANENT COVER.
