It is assumed that Metropolitan Council projections pertain to Mounds View only and do not include flows entering the interceptors from outside City limits. Table 2-4 - Average Wastewater Flow Projections - Metropolitan Council Year Mounds View Projected Average Flow (MG 1 1 1• 1 1 1 1�1 1 The flow projections presented in the appendices are developed from the land use in Appendix A, which is based on the City's 2040 land use plan (included in Appendix F). It should be noted that the total average daily flow of Appendix B exceeds the projected 2040 flow of Table 2-4, largely due to conservative application of the flow model concerning the capacity and design of City trunk lines. The unit flow rates used in the modeling correspond to typical maximum values for a land use category; they are listed in Table 3-1. The conservative approach to estimating flows allows the City to remain flexible in planning future development, providing sewer capacity for localized development of higher intensity use, and protecting against potential backups.
