The apphcant has included a project description which provides information regarding both the lift station and interceptor projects. PLANNING COMMISSION The Planning Commission reviewed the item at their May 23, 2006 meeting The Commission heard the staff report and additional information from the apphcant's representative Jim Roth There was no one who spoke at the pubhc hearing and there were no questions for the apphcant. The Commission unanimously approved the two conditional use permits for the two hft stanons. DISCUSSION The footprint of both of the buildings approximates 4,000 square feet and is relatively square. Each site will contain a paved driveway and parking lot as well as building and landscaping. L74 Lift Station The station will be located on the 35 acres Wastewater Treatment site in the eastern portion of the community. The site currently gams access from 140` street and the station will use the same driveway as the existing facility The hft station is located west of the treatment plan Building elevations illustrate a structure that is more industrial m character with little adornment. The entire facade is masonry with pedestrian doors, windows and overhead doors breaking up the elevations. Because of the type of use, there are few windows, however the design calls for recessed brick panels consistent in size and rhythm of the windows. Grading will occur on the site to facilitate construction of the building Grades are slightly steeper in the northwest, prompting the need for a retaining wall along the western edge. Seven deciduous trees, three ornamental trees and three coniferous trees will be installed as part of the site development. L75 Lift Station The building is located by easement on a 257 acre parcel owned by UMORE. Access will be via a private driveway with direct access unto County Road 42. Should development ever occur m the area, the City would look to relocate the driveway so it does not directly access County Road 42. The access, in the interim, should be paved and curbed consistent with the city standards for any development. The building elevations differ from the previous lift station because of its location. The exterior materials continue to be all masonry although the building undulation and peaked roof are more reminiscent of a residential structure than a utihtanan building The most visible elevation will be to the north There the design has some variation m bnck and a pedestrian access is provided. The south elevation has the overhead door with both the east and west having aluminum louvers. The site slopes from west to east. Grading will occur to provide a flat building pad. The driveway grade is relatively steep with a 5.8% grade. However, httle traffic is expected In recognition of the higher profile location, there are 15 deciduous tress, 15 coniferous trees and nine ornamental trees proposed Consistent with the landscaping ordinance, and due to the site's visibility, foundanon plantings should be added to the plan. Immediately adjacent to the building and paving, the lawn will be maintained with the outside edges planted in a native prairie mix Staff recommends a few modifications to the proposed site plan for L75. The apphcant should submit a utility plan showing extension of watermam under CR42 for final review and approval The plans should be modified to provide foundation plantings around the building and the maintained area should be irrigated. The driveway should realign m the future when development occurs so that it does not directly access CR42. For both of the plans, staff is requesting the applicant work with the Fire Marshall to locate fire hydrants in the appropriate locations. And extenor materials samples are requested for all materials, both the masonry and other. Staff is hoping items such as the louvers can be colored or coated in such a way that they blend into the building facade rather than contrast with the masonry colors. CONCLUSION Staff is comfortable with the two applications and supports moving forward with the project. The two lift stations are an integral part of the entire interceptor project which will provide sanitary sewer service to much of the community. There are minor concerns noted which primarily have to do with aesthetics on the more visible UMORE site. Recommended conditions of approval are provided to address these concerns. RECOMMENDATION Approve the attached resolutions. 2 CITY OF ROSEMOUNT DAKOTA COUNTY, MINNESOTA RESOLUTION 2006 A RESOLUTION APPROVING THE CONDITIONAL USE PERMIT (CUP) FOR LIFT STATION L74 WHEREAS, the Community Development Department of the City of Rosemount received an application from Metropolitan Council Environmental Services requesting a Conditional Use Permit (CUP) for the construction of Lift Station L74 to be located at 4005 140` Street, Rosemount and legally described as: The Southwest Quarter of the Southeast Quarter (SW1 /4 of SE1 /4), except the East 35 feet and the North 125 feet thereof, Section 19, Township 115, Range 18.

The attached map shows the route of the interceptor and locations of the Lift Stations. L74 is located at the Rosemount WWTP site at 4005 140 Street East. L74 will serve development in the eastern one -third of Rosemount. D Lift station L75 is on UMORE Park property located approximately 4000 feet west of Akron Avenue on County Road 42 opposite the intersection of Aubum Avenue and County Road 42. L75 will serve the central third of Rosemount and will also repump flow from L74 The western one -third of Rosemount will be served through a gravity connection to the new interceptor near the intersection of County Road 42 and Biscayne Avenue The length of the interceptor is 10 miles, approximately six of which are located in Rosemount. The description of the interceptor system is: In 2004 the Rosemount Facility plan was adopted by the Metropolitan Council with a recommendation to take the Rosemount Wastewater Treatment Plant (WWTP) out of service and construct an interceptor to transport and treat flow from Rosemount at the Empire WWTP. The timing of the project was such that the interceptor pipeline could be constructed concurrently along a common alignment with the Empire WWTP effluent outfall transporting treated wastewater from the plant to the Mississippi River near Pine Bend. The project is needed in order for Metropolitan Council Environmental Services (MCES) to meet its wastewater service needs to accommodate community growth in Rosemount. The Rosemount interceptor is a 10 mile pipeline extending from the existing Rosemount WWTP site located at 4005 140 Street East to the Empire WWTP located near 197 Street and Biscayne Avenue in Empire Township Because of the topography of the land between the two sites, two sewage pumping stations or lift stations are required to elevate or lft the sewage to elevations where the sewage can flow in gravity pipelines to its destination MCES has designated the two sewage pumping stations L74 and L75 in accordance with its convention for designating sewage pumping stations. This Conditional Use Permit Application is to meet the City's requirements for conditional uses of the sewage pumping station sites. From L74, sewage is pumped in dual 18 -inch pipes to a high point on County Road 42 near Blaine Avenue. The route of the forcemam is west along 140 Street to a location 1300 feet west of STH 52, thence south across open land to CSAH 42, thence west along the south side of CSAH 42 The length of the forcemam from L74 is approximately 9800 feet From the end of the L74 forcemam near Blaine Avenue the sewage flows by gravity in 36- inch and 42- inch pipes to the L75 site on the south side of County Road 42. A major trunk connection is to be located at Akron Avenue to connect with the existing MCES interceptor APR 2 6 ZOOS By and to serve the center part of Rosemount north of County Road 42. This trunk sewer is to be constructed as part of the Akron Avenue /County Road 73 improvements From L75, the sewage is pumped in dual 24 -inch pipes The route of the forcemain is west along CSAH 42 and has a length of 550 feet From the end of the L75 forcemain, the sewage flows in gravity interceptor to the Empire WWTP in 42 -inch and 48 -inch pipes that follows an alignment west on CSAH 42, thence south on Biscayne Avenue. Lift Station Features Both lift station are to be built -in -place structures designed to provide long -time service in the MCES system. The buildings are designed to accommodate additional and larger equipment to accommodate growth in Rosemount. For example, initially each lift station will have four (4) sewage pumps. The building is sized to accommodate up to six (6) sewage pumps as flows increase. Other lift station features are. Concrete, bnck and masonry construction. Standby diesel power generator to operate the station in event of a power failure. Ventilation odor control using activated carbon filters. Forcemain odor and corrosion control using liquid chemical addition. Site grading and landscaping to enhance site appearance. Construction Contracts and Schedule The lift station will be constructed in one construction contract. The interceptor pipeline is being constructed under three separate contracts, all of which are underway and are scheduled for completion in late 2007. The tentative schedule for the lift station construction contract is: Advertise For Bids Receive Bids Construction Ndtice to Proceed Substantial Completion Final Completion Activity Date June 2006 July 2006 October 2006 March 2008 June 2008
