The timing of the possible expansions would depend on funding and need. The first priority would be to connect all commercial establishments to public sanitary sewer. A second priority would be properties where soil or topographic conditions make the installation of an ISTS difficult. Goals and Policies Goals • Maintain the high quality natural environment • Meet water quality standards • Provide a sanitary sewer system that is cost-efficient to the City and which encourages a fiscally responsible development pattern Policies • City to extend sewer mains as needed as shown in Figure 7.1- Sanitary Sewer Comprehensive Plan. The first priority shall be commercial establishments. The second priority will be areas where soil or topographic conditions limit effectiveness of onsite sewage disposal systems. • Onsite sewage disposal systems will not be allowed where there exists a service limitation, such as wetness, low soil percolation and other unfavorable soil conditions. • Further written working agreements with Vadnais Heights and MCES will be sought, as necessary, to coordinate required extension of sewage service to their systems. • Appropriate on -site disposal regulations will continue to be enforced in those areas not served by the centralized sanitary sewer system. Minnesota Department of Health and Minnesota Pollution Control Agency (MPCA) standards for installation of ISTS will be strictly enforced. • The bi-annual inspection of all individual sewage treatment systems in the City will be continued. • Water pollution from onsite treatment systems will be minimized. • All applicable state or federal requirements for sewage effluent will be met or exceeded. • Wastewater generation served by ISTS systems will be required by the City to connect to the public system within one year of the time service is made available. • A capital improvements program, which includes sewer system improvements, will be developed. • Minimum lot sizes adequate to provide for all expected improvements to ISTS systems will be required. This will allow for the installation of two ISTS systems to help ensure space for an alternate system or system expansion, in case of inadequacy or failure. • A continuing education program on the function and maintenance of ISTS systems will be established. • Outside funding sources f'or programs to locate and upgrade substandard wells and ISTS systems will be sought. • When sewer service is available, larger lots are encouraged to subdivide. These lots should meet Met Council standards for density and be at least 3-units per acre. SE H I 7.0 sanitary sewer system plan I page 49
