usage is estimated to be 200,700 gallons per day, based on a peaking factor of 3. Annual water useage is projected to be 73 million gallons per year. The current Minnesota Department of Natural Resources water appropriations permit will need to be amended to provide for this water usage. The City of Ramsey's water supply system will need to be expanded to provide water for this development. Capacity equivalent to a peak flow of 46 gallons per minute will be required. This is equal to approximately 4% of a single new well typically constructed for the City. The City o f Ramsey trunk water distribution system will be extended to serve the development. Water flow and pressure will be adequate for service to the development area. Based on the additional projected average day water usage for the development, current water storage capacity for the City will be fully utilized. Future water storage planned fbr the system will be adequate for providing service to the development. Future storage is planned as part of the Water Treatment Facility, and as a new water storage tower. In addition, a raw water transmission main is projected to be constructed in right-of-way easements included as part of this development. Dewatering may be necessary when excavating the basements and utilities trenches that extend below the groundwater level. Wells needed tbr dewatering the site during construction will pass through the Minnesota DNR permitting process. Dewatermg of site locations for the construction of ponds and the installation of utilities will be of short duration. Wells on adjacent properties are not anticipated to be impacted by this short term dewatering. These wells will be monitored during the dewatering process. .,,].4,,;,W.~a4~r.l?{~[~t~d;r . . .,, ,, ~t, . : [~,. a~l_di.Us~.:Ma[.]~..~,....,, x. ~.. , .. ~: ,- ~ ....... :'": '"' > '"'"-: :: ~[~~3~'"?
