<br />north and directly into storm sewer pipe in,Center Pointe Drive. The existing storm <br />sewer eventually discharges into a City retention pond adjacent to DNR wetland 62-50. <br /> <br />Sanitary SewerlWater Demand , <br />Sanitary sewer has been extended to the site rrom the existing sewer main located in . <br />Centre Pointe Drive. <br /> <br />Sanitary sewer will be handled by the City ofRoseville system. It is estimated that the, <br />proposed improvements will contribute a peak flow of20 gpnito the sanitary 'sewer. <br />system. Existing 8 inch and 10 inch sanitary sewers exist in Centre Pointe Drive, Lydia <br />Avenue and Clevel3;nd Avenue. These gravity lines flow to a lift station located about <br />600 feet north of Lydia Avenue on the west side of Cleveland Avenue. This lift station <br />was upgraded in 1987 to handle all flowsftom the Centre Pointe development. The <br />sewer lines are located such that they will handle most or all of the site.' All the sewers <br />ultimately reach the trunk sewer line in lona Lane then onto the Metro Treatment Plant in <br />St. Paul.' ' ' <br /> <br />The City ofRoseville municipal water supply will be used to provide domestic water <br />supply to the city. Roseville receives its water ftom the City of St. Paul. Assuming a . <br />daily consumption rate of800 - 1500 gallons per acre per day for commercial pses, total, <br />consumption for the site would be 2,376-4,455 gallons per day for the 2.97-acre site. <br />According to the St. Paul Water Utility, the maximum capacity of their water supply <br />facility is 168 million gallons per day and their current average utilizatiop rate is 52 <br />million gallons per day. There is suffipient capacity to accommodate the estimated <br />maximum demand of 4,455 gallons per day forthe .~ite. <br /> <br />Based on the above, we. believe there .is no need to prepare a new EA W. The March 1997 <br />EAW still adequately analyzes ~he effects of the proposed develo'pment. Please feel ftee <br />to contact RLK with any questions pertaining to the above information. <br /> <br />Sincerely, <br /> <br />p:~p <br /> <br /> <br />Joseph'M.
