corresponding allowable peak flow, reached during precipitation events, would be a maximum of just under 2.0 mgd. Therefore, the station’s reserve capacity is approximately 3.8 mgd. Based on the MCES Sewer Available Charge (SAC) Program, the estimated peak flows generated by the Zoning Scenario and Maximum Development Scenario are 2.42 mgd and 2.75 mdg, respectively. Therefore, in the Maximum Development Scenario approximately 1.05 mgd of capacity would remain at the lift station after the development of the AUAR study area. Both the lift station and the regional interceptors serving the study area and southeast Mounds View have sufficient capacity to accommodate the additional flow required in each Scenario. Regional wastewater collection and treatment facilities and municipal wastewater pipes serving the study area have sufficient long-term capacity to handle the additional wastewater flow generated by both the Zoning and Maximum Development Scenarios. Sanitary sewer will need to be extended into the AUAR study area to provide sewer service to the various lots. The use of a small lift station may be required depending on future uses, but the system will primarily be gravity-based. 2) I(SSTS), F THE WASTEWATER DISCHARGE IS TO A SUBSURFACE SEWAGE TREATMENT SYSTEMS ,, DESCRIBE THE SYSTEM USED THE DESIGN FLOW AND SUITABILITY OF SITE CONDITIONS FOR SUCH .

LIMITATIONS DURING AND AFTER PROJECT CONSTRUCTION Stormwater will be managed on-site, maintaining the current drainage patterns and utilizing the current outfalls to Rice Creek and Round Lake. The site will require compliance with Rice Creek Watershed District (RCWD) rules for water quality, volume control, runoff control and erosion control. As required by RCWD, the quantity of stormwater runoff in post-development conditions will not exceed existing conditions. The runoff rate will be reduced to 80% of the existing rate because the AUAR study area is located within a Flood Management Zone as defined by RCWD. There are three existing outfalls to Rice Creek with an approximate capacity of 500 cubic feet per second, and one outfall to Round Lake with a capacity of approximately 200 cubic feet per second. Infrastructure improvements will include the rehabilitation or replacement of existing outfalls that are determined to be in poor condition. June 2014– Final AUAR12
