Home My WebLink About 2.b. Comp Plan Amendment for Sewer Capacitye CITY OF ROSEMOUNT EXECUTIVE SUMMARY FOR DISCUSSION COMMITTEE OF THE WHOLE MEETING DATE: July 11, 2001 AGENDA ITEM: Comp Plan Amendment for Sewer Capacity PREPARED BY: Rick Pearson, City Planner 99 ATTACHMENTS: Service District boundary map, Correspondence SUMMARY The Council may recall that Staff received correspondence from Met Council indicating a need to amend the Comprehensive Plan regarding the sanitary sewer diversion to the Empire Waste Water Treatment Plant. At issue was the Met Council concern that more effluent was being sent to Empire than was indicated in the 2020 Comprehensive Plan. The amendment process was suggested by Met Council to acknowledge the "overage" and establish a contingency plan to divert some of the difference back to the Rosemount Waste Water Treatment Plant in case of capacity issues at Empire. Therefore, Staff has been preparing the information necessary to process the amendment. A public hearing is required, which could be conducted as soon as July 24. However, Michael King, the Met Council Staff liason to Rosemount has suggested a meeting prior to initiating the amendment. This meeting is tentatively scheduled for the week of July 16 -20. In the mean time, staff feels that there may be sewer treatment capacity concerns relative to the remaining vacant land within the Empire Waste Water Treatment service area. The amount of land is not extensive, staff estimates approximately 104 acres of land are available. The obvious impact may be to adopt a development moratorium on the land until the sewer capacity issue is resolved. Staff is seeking Council direction RECOMMENDED ACTION: Intended for discussion and direction only.

Over the last 9 months the flows from the City of Rosemount to the Empire WWTP have increased from an average daily flow of .27 mgd to .32 mgd which will be adequate through 2005 based on the comprehensive plans of the tributary communities. On January 26, 2000, the Metropolitan Council acted on the comprehensive plan for the City of Rosemount. The comprehensive plan for the City indicated that the 2005 flow from the Empire WWTp service area would be 0.3 mgd and the 2020 flow would be 0.35 mgd. The existing Empire WWTP has a capacity of 12 mgd. The schedule for the expansion of the Empire WWTP is very tight. For this reason, all the tributary communities to the Empire plant must keep their flows within the limits defined by their comprehensive plans until additional capacity can be provided. The Metropolitan Council has approved the hiring of a consultant to evaluate the capacity of the existing Empire WWTP and to recommend possible interim capacity improvements to the plant. This study should be completed in September of 2001. At the April 11 meeting, the City indicated that a mistake had been made in calculating the projected flows from the City's Empire WWTP service area. The City indicated that approximately 149 vacant sewered residential lots, a portion of the City's industrial park, and the tributary to the service area could add an additional flow of up to 0.23 mgd to the service area for a total flow of 0.55 mgd. Since the flow from this area of the City has already exceeded the 0.3 mgd limit within the Empire service district, the City will have to amend its comprehensive plan to be allowed to add additional flows to t e his area. Th WTP remaining capacity at the Empire W has been committed to other tributary communities through the approval of their comprehensive plans. A plan amendment requesting additional capacity, to t supported by staff, must include a plan to divert flows greater then 0.3 mgd to the Rosemount WWTP if the MC deems it necessary. If you have any questions, please contact Mr. Donald Bluhm at telephone number 651- 602 -1116 of my staff. Sincerely, William G.
