D. SYSTEM EXTENSION FOR 167T1 AVENUE SPECIAL AREA The Special Area boundaries are shown on the map in Item H of the Appendix. With the exception of the westerly 40 acres, this area is not within the 2030 MUSA. It does, however, include one of the development "hot spots" shown on Figure 1 and is adjacent to another. Sewer service to this area was planned to be provided by extension of trunk sewer from the existing 30- inch trunk sewer for the Rum River District as shown on Figure 1. This was referred to as the Northeast Trunk Sewer and was studied in detail in a 2004 feasibility study. The southerly 30- inch sewer proposed in the feasibility study was constructed with the Northwest Trunk Sewer project in 2006. The Northwest Trunk Sewer is sized to ultimately accommodate the sewer flow from the entire northeast portion of the City. The Special Area consists of an estimated 189 acres of developable residential property and 7 acres of commercial property. This is a very small portion of the ultimate service area for the Northeast Trunk. There is commercial property and also a development "hot spot" on the east side of Highway 47 which is not in the Special Area but should be considered as additions to the area. With the small initial service area, a second option for providing sewer service to the Special Area consisting of a lift station and 8-inch forcemain is proposed as Alternate 2. The lift station would be located within the Special Area. For cost estimating purposes, the forcemain is assumed to follow the same route proposed for the gravity sewer. This lift station and forcemain are sized to accommodate the ultimate sewer flow from only the Special Area. The lift station and forcemain capacity could be increased to allow expansion of the Special Area. E. SANITARY SEWER SERVICE AREAS The system extensions discussed above will extend sewer service to the 2030 MUSA area and the 167t1i Avenue Special Area. In addition, the 2030 MUSA area extensions can also service areas beyond the 2030 MUSA boundaries. This information is summarized in Table 4.2.
