Nineteen lift stations <br />are needed to transport sewage to the treatment plant. The City provides sanitary <br />sewer service only within the Urban Service Area (see discussion later in this <br />section). The Urban Service Area identifIes the outer limits for extending sanitary <br />sewer and water systems under current plant and system capabilities. <br /> <br />The size and location of the collection system also influences the ability to expand <br />the system. One area of constraint examined in the planning process is the Mining <br />area. The 2004 sewer system study estimated that the Jackson Street lift station <br />has approximately 100,000 gpd of excess capacity. This capacity would allow for <br />approximately 100 acres of new development on the mining area. The study <br />concluded that bringing additional capacity to the gravel mnining area would require <br />the construction of a new trunk interceptor from this area to the treatment plant. <br /> <br />The implications of these constraints on development cannot be determined <br />without additional planning. For this reason, the land use for the area is a reserve- <br />like Mining designation. This approach allows management of continued mineral <br />extraction and defers future land use decisions until more information on sewer <br />capacity is available. A future amendment of the Comprehensive Plan will be <br />needed for this area. <br /> <br />As mineral extraction is completed in the southern portions of the Mining area, <br />the need to plan for development will increase. Additional investigations will be <br />needed to determine: <br /> <br />. <br /> <br />Land uses supportable with existing capacity in the Jackson Street lift <br /> <br />station. <br /> <br />. <br /> <br />Financial implications for the City and property owners from the necessary <br /> <br />improvements. <br /> <br /> <br />Building the Future - A Comprehensive Plan for Elk River <br /> <br />8.2 <br />
