Mr. Michael Grochala <br />April 8, 2020 <br />Page 4 <br /> <br /> <br />K:\015144-000\Admin\Docs\AUAR - Update 2020\Water Wastewater\MEMO - 040820 - Wastewater.docx <br />2020 Scenario 2 <br />The proposed development within the study area for Scenario 2, the assumed wastewater flow <br />for each land use type, and the projected wastewater flow for that development are summarized <br />in Table 5. There are a number of properties within the southern portion of the study area that are <br />already sewered, so these areas have been removed from the areas listed in Table 5. <br /> <br />Table 5.
