30 I I I I I I I I I I I I I I I I I I I Critical and Scenic Rivers Areas The City of Ramsey has established ordinances which regulate building activities in the Shorelands and Mississippi River Critical Area District as well as a Scenic River Ordinance. The Shorelands and Critical Area District regulates building along the Mississippi River and protected waters in the City. The Scenic River Ordinance regulates building along the Rum River. Anoka County has jurisdiction over septic systems in the Shoreland Ordinance area which includes the Rum River. Flood Plains Ramsey Code does not allow soil treatment areas to be placed in flood plains delineated by local ordinance adopted in compliance with the Statewide Standards and Criteria for Management of Flood Plain Areas of Minnesota (Minn. Reg. NE 85-93), orin areas for which regional flood information is available from the Department of Natural Resources. Septic System Replacement Policy The policy' of the City of Ramsey is to protect public health and protect the environment by requiring prompt repair or replacement of failed septic systems with properly designed and installed septic systems. Correction of failed septic systems is by replacement of individual sewage treatment systems (ISTS). Each replacement ISTS on the affected property must conform with current code standards. IX. SANITARY SEWER SYSTEM SanitarY Sewer Svstems Figure 11 shows existing sanitary sewer systems as of 1990 and indicates the proposed development schedule for extending sewer in the 2000 MUSA areas. Each area is identified alphabetically and can be cross referenced to Tables 13 and 14. Table 13 provides a projection of wastewater flows for the Mississippi River Watershed through the year 2000. As indicated, Table 13 residential flow in this watershed is relatively low with a projected ultimate flow of 0.041 million gallons day (mgd) or 14.97 million ga/lons per year. This watershed is zoned predominantly for industrial use, thus the heaviest contributor to wastewater flows in this watershed will be industrial users. The total projected flow for all land uses for the year 2000 is 0.668 mgd or 243 million gallons/year. Table 14 provides a projection of wastewater flows for the Rum River Watershed through the year 2000. As indicated, residential land use will be the primary contributor to these flows with approximately 96% of the total flow projected for the year 2000. Residential flow is projected to be 0.341 mgd with total projected flow of 0.356 mgd (129.9 million gallons per year). Table 15 summarizes the developed and undeveloped acreage by watershed as of 1989 and estimates the development area for the 2000 MUSA. As indicated, the developed acreage within the sewered area of both watersheds is projected to double by the year 2000. The estimated project that approximately 80% of the net developable acreage within the 2000 MUSA would be developed by the year 2000.
