E. Ground Water <br /> <br />Ge <br /> <br />Based on pond levels in the area, ground water will be <br />encountered during the construction of public utilities. The <br />EAW states that the average groundwater depth is 5.5 feet <br />below the surface. Consequently, dewatering will be required <br />during construction using wells, well points, sump pumps and <br />deep wells. Once the project is complete, ground water levels <br />will return to normal. Ground water quality should not be <br />affected by this project since the ground water will exert a <br />positive pressure on the proposed sewers and seep into them <br />rather than have the wastewater seep out. Infiltration rates <br />will be limited to 100 gallons/day/inch of diameter/mile. (EAW <br />and city's Comprehensive Sewer Plan.) <br /> <br />Shorelands, Floodplains, Wetlands and Rivers <br /> <br />The development encompasses parts of three shoreland districts <br />which are also protected wetlands No. 2-113, No. 2-114 and No. <br />2-116. None of the proposed lots are waterfront lots. <br />Therefore, the minimum lot size for the shoreland district <br />adjacent to wetland No. 2-113 is 15,000 square feet and the <br />minimum lot size for the shorelands adjacent to wetland No. <br />2-114 and No. 2-116 is 10,000 square feet. A permit to <br />discharge storm water into the protected wetlands will be <br />obtained from the DNR. (Comments to EAW and EAW) <br /> <br />Surface Water Quality <br /> <br />Disposal of wastewater from the project will be made through <br />the Ramsey sewer system and the MWCC interceptors with <br />treatment at the Anoka Treatment Plant. At the time the Anoka <br />Treatment Plant is phased out, wastewater will be diverted to <br />the MWCC Treatment Plant in St. Paul (Pig's Eye). <br /> <br />Surface water runoff from the project will flow into both <br />wetland No. 2-114W and No. 2-116W. The wetland will serve as <br />a storm water holding pond for the stormwater. It is also <br />proposed to increase the capacity of wetland No. 2-116W by 500 <br />cubic yards. Erosion control fences will be placed along the <br />downslope sides of all disturbed areas and all disturbed areas <br />will be seeded. (EAW) <br /> <br />Air Quality and Noise <br /> <br />Dust control measures will be used when needed. The local <br />noise control ordinances of Ramsey will be complied with. <br />(EAW) <br /> <br /> <br />
