In order to accurately reflect actual housing densities, the 1991 Comprehensive plan completed by Hakanson Anderson Associates, Inc. incorporated a detailed review of the impact that existing development would have on future development densities. The areas outside of the City's urban service boundary were permitted to subdivide into lot sizes of one acre and larger. According to the 1991 sewer plan, at the time of the report, approximately 1/3 of the land in the City's rural transition area was undeveloped. Based on this, the 1991 report attempted to project practical development density, which resulted in a development density of less than 2.5 units per acre in many areas. Ultimate sanitary sewer flows were calculated based on development assumptions for the following major land -planning categories: Urban: This planning area consisted of land that was within the current metropolitan service area, which had been expanded to the 2000 MUSA line. Housing densities in this area were primarily fixed by existing development and preliminary plats and proposals. Sewer flow within the 2000 MUSA line was calculated based on the number of existing and proposed lots and the assumption that undeveloped land would develop at the same density as adjacent properties. Urban Reserve: This planning area consisted of land outside of the 2000 MUSA line but within the City's designated urban area. Land use controls at the time the 1991 plan was completed required a minimum lot size of 10 acres in an attempt to limit the subdivision of land until the MUSA line was extended into the urban reserve area. Sewer flow in this area was calculated based on densities similar to the MUSA lands except that development potential was restricted by existing plats with large lots. Rural Transition: This planning area consisted of land within the Metroplitan Waste Control Commission's Sewer Service District number 3 boundary (land south of Trott Brook) but outside of the City's designated urban area. At the time of the 1991 plan, there were no plans to extend sewer into this area. However, the plan did note that long range planning recognized the potential for sewer service to this area and therefore major facilities had been sized accordingly.
