be penetrated by the trench and drained. If necessary, a horizontal confining layer of loxv-permeability soils will be <br />restored. <br />The enabled development within the City of Ramsey may create the need for additional water supply for the city. A <br />new water main will be constructed to serve the Puke Homes Pine Shadows development. Any new wells would be <br />constructed with MDlt and DNR requirements and approvals. <br /> <br />Does any part of the project involve a shoreland zoning district, a delineated 100-year <br />flood plain, or a state or federally designated.wild or scenic river land use district.9 <br /> <br />If yes, identify the district and discuss project compatibility with district land use <br />restrictions. <br /> [] ,.No' <br /> I~ Yes <br /> The Mississippi River is designated as "recreational" from Clearwater to the AnokaTCl;iamplin line. The Mississippi <br /> River Critical Area/Mississippi National River and Recreation Area also applies to the river near Ramsey. This <br /> project is in FEMA Zone C (area outside ct'the 100-year floodplain) of the Mississippi River. It is not in a state or <br /> federally designated wild or scenic river land use district. <br /> <br />Will the project change the number or type of watercraft on any.water body? <br /> <br />If yes, indicate the current and projected watercraft usage and discuss any potential <br />overcrowding or conflicts with other uses. <br /> [] No <br /> [] Yes <br /> The project itself will not cl3ange the number of watercraft on any water bodies in the project area. <br /> <br />-476- <br /> <br />Give the acreage to be graded or excavated and the cubic yards of soil to be moved.' <br />Describe any steep slopes or highly erodible soils and identify them on the site map. <br />Describe any erosion and sedimentation control measures to be used during and after <br />project construction. <br />Acres 26.8 Cubic Yards 126,948 CY (based On a length of 7,790 fi, an a{,erage depth of <br /> 20-fi and 1:'1 side slopes) <br /> Regardless of the soil erosion potential, erosion control measures will be implemented. Specific measures to be <br /> used will be detailed in the erosi0n'control plans required as part ofthe.NPDES permit. In general, high flow areas <br /> will be protected with turf reinforcement mats. Any potential high flows from off'site will be mitigated as they <br /> enter the construction site. Measures may include the use of high flow silt fence, checkdams, biologs, and/or <br /> stilling basins. Disturbed areas will be seeded and stabilized as soon as possible after construction. A fiber blanket <br /> or hydraulic seed stabilizer may also be used. Erosion control is also discussed in Item 12 of this EAW. <br /> The majority of excavated soil will be returned to the construction trench after placement of the pipe. Any excess <br /> soil will be disposed of in upland areas where sediment will not impact water resources or other sensitive areas. <br /> Soil erosion control practices will be implemented t6 minimize impacts to wetlands and other surface waters in the <br /> vicinity ct'the project. Best management practices will be implemented, Construction practices will be managed to <br /> limit the duration of exposed soil to wind and min. <br /> Detailed temporary and permanent sediment ariel"erosion control plans must be prepared in accordance with the <br /> MPCA National Pollutant Discharge Elimination System (NPDES) General Stormwater Construction Permit. A <br /> Storm Water Pollution Prevention Plan (SWPPP) will. be submitted tbr review and approval. Erosion control <br /> <br /> <br />
