EXECUTIVE SUMMARY The Hawkins Sanitary Sewer Extension Project, City Project No. 438, was initiated by Hawkins, Inc. with a proposal to redevelop their site with sanitary sewer service. The site is located southwest and adjacent to Minnesota Trunk Highway 55 (MN T.H. 55); east of and adjacent to Clayton Avenue (T.H. 52); north of 140 Street (Refer to Figure 1 of Appendix A for a Project Location Map). Two cost estimates have been prepared for the sanitary sewer extension through the former Continental Nitrogen site, being developed by Hawkins, Inc. The first estimate considers the costs associated with extending trunk sanitary sewer to the future building at the Hawkins site, identified as Lot A in Figure 2 of Appendix A. This estimate mirrors the sanitary sewer limits proposed by the Larson Engineering, Inc. for Hawkins, Inc. The second estimate considers the costs associated with extending trunk sanitary sewer facilities to the western limits of the Feed Products North, Inc. site, identified as Lot B in Figure 2 of Appendix B. It is estimated that the total costs associated with extending trunk sanitary sewer facilities to the Hawkins site are $273,100. The total costs associated with extending sanitary sewer facilities to the western limits of the Feed Products North, Inc. site are estimated to be $293,500. Detailed cost estimates for both of these scenarios can be found in Appendix B of this report. It is proposed that the extension of sanitary sewer facilities to the Hawkins site commence prior to construction of the warehouse and tank farm. Based on the need for sanitary sewer service to redevelop the site, this project is feasible, necessary, and cost - effective from an engineering standpoint, and should be constructed as proposed herein. 2. STREET IMPROVEMENT PROJECT 2.1 Introduction 2.1.1 Authorization On September 6, 2011, the Rosemount City Council authorized the preparation of an Engineering Feasibility Report for the Hawkins Sanitary Sewer Extension. This project has been designated as City Project No. 438. 2.1.2 Scope The extension of sanitary sewer facilities to the Hawkins site is necessary to provide sewer service to the proposed warehouse and tank farm building. The City of Rosemount's Comprehensive Sanitary Sewer System Plan identifies flow from both the Hawkins site and the adjacent Feed Products North, Inc. site will travel via gravity sewer through the Hawkins site to the 15 -inch gravity sewer main that was constructed in 2007 with the Flint Hills Resources site improvements. Therefore, the extension of trunk sanitary sewer facilities to the Hawkins site must be evaluated to determine future serviceability of the adjacent Feed Products North, Inc. site. Feasibility Report Hawkins Sanitary Server Extension City of Rosemount Project No. 438 WSB Project No. 1916 -46 Page I 2.1.3 Data Available Information and materials used in the preparation of this report include the following: • City of Rosemount Utility Plans • City of Rosemount Record Plans • City of Rosemount Topography Maps • Boundary and Topographic Survey data prepared by MFRA Associates, Inc., dated June 14, 2011 for the Hawkins site • Proposed Utility and Grading. Plans prepared by Larson Engineering, Inc., dated July 26, 2011 for the Hawkins site 2.2 General Background 2.2.1 Project Location The project area is located in the northeast corner of the City of Rosemount, is zoned HI, Heavy Industrial, and is located within the Metropolitan Urban Service Area (MUSA). The properties evaluated for sanitary sewer serviceability include: The Hawkins site (identified as Lot A within Figure 2 of Appendix A) The Feed Products North, Inc. site (identified as Lot B within Figure 2 of Appendix A) 2.2.2 Project History This project was initiated by Hawkins, Inc. with a proposal to redevelop their site with sanitary sewer service. The City of Rosemount's Comprehensive Sanitary Sewer System Plan identifies flow from both the Hawkins site and the adjacent Feed Products North, Inc. site will travel via gravity sewer through the Hawkins site to the 15 -inch gravity sewer main that was constructed in 2007 with the Flint Hills Resources site improvements. 2.3 Existing Conditions 2.3.2 Sanitary Sewer 15 -inch gravity sanitary sewer was extended to the southwest corner of the site with the Flint Hills Resources improvements in 2007. The City of Rosemount's Comprehensive Sanitary Sewer System Plan identifies flow from both the Hawkins site and the adjacent Feed Products North, Inc. site will travel via gravity sewer through the Hawkins site to this existing trunk sanitary sewer system. Feasibility Report Hawkins sanitary Sewer Extension City of Rosemount Project No. 438 WSB Project No. 1916 -46 I'age 2 2.4 Proposed Improvements 24.1 Sanitary Sewer Extension of trunk sanitary sewer facilities through the Hawkins site shall follow the western and northern access drive limits wherever possible, so as to provide access for inspection and maintenance purposes. The City of Rosemount's Comprehensive Sanitary Sewer System Plan identifies flow from both the Hawkins site and the adjacent Feed Products North, Inc. site will travel via gravity sewer through the Hawkins site to the 15 -inch gravity sewer main that was constructed in 2007 with the Flint Hills Resources site improvements. The combined area of the Hawkins and Feed Products North, Inc. sites is approximately 53- acres. Based on the designated industrial land use for these lots, it is assumed that approximately 1,500 gallons /acre /day of average wastewater flow will be generated by the two sites. Using a peaking factor -of 3.9, the anticipated peak flow from the two sites is therefore: 53 acres * 1,500 gal /acre /day * 3.9 = 310,050 gal /day The capacity of an 8 -inch sanitary sewer pipe constructed at the minimum pipe grade specified by the 10 -State Standards (0.4 %) is 493,000 gal /day. The anticipated peak flows from the Hawkins and Feed Products North, Inc. sites were calculated using general wastewater flow information for land guided for industrial use. The developer of the Hawkins site is encouraged to submit to the City for review detailed wastewater generation calculations prior to final plan approval to verify peak demand requirements. 2.4.2 Permits /Approvals A Sanitary Sewer Modification Permit from the Minnesota Pollution Control Agency (MPCA) will be required to complete the sanitary sewer extension through the Hawkins property. 2.4.3 Easements A permanent drainage and utility easement will be required over the length of the proposed sanitary sewer improvements, and shall include the area through the railroad track crossing. The easement shall also extend across the proposed access drive to the Clayton Avenue (T.H. 55) right -of -way such that the City's Public Works Department will have a means by which to access the proposed sanitary sewer improvements for both inspection and maintenance purposes. The easement shall be a minimum of 40 -feet in width for the length of the sanitary sewer improvements across the Hawkins property, and shall be 60 -feet in width in those areas where the depth of the proposed sanitary sewer improvements are approaching 30 -feet.

Feasibility Report Hawkins Sanitary Server Extension City of Rosemount Project No. 438 WSB Project No. 1916 -46 Page 4 3. FINANCING 3.1 Opinion of Cost Detailed opinions of cost can be found in Appendix B of this report. The opinions of cost incorporate estimated 2011 construction costs and include a 10% contingency and 30% for all related indirect costs (legal, administrative, engineering, and financing items). Table 1 below provides a summary of the opinion of probable cost for the Hawkins Sanitary Sewer Extension. Table 1 - Summary of Cost Steel Casing Sanitary Sewer Total Costs Extension Costs Option #1— Extension to Future Building at $62,565 $210,535 $273,100 Hawkins Site Option #2 — Extension to Feed Products $62,565 $230,935 $293,500 North, Inc. Site 3.2 Funding Construction of the Hawkins Sanitary Sewer Extension improvements will be 100% developer funded if the limits of construction are to the future building proposed within the Hawkins Inc. site, and are estimated to be $273,100. Extension of trunk sanitary sewer facilities to the Feed Products North, Inc. site is estimated to be $293,500. The costs associated with installing the required 36" steel casing beneath the proposed railroad extension ($62,565) will be 100% funded by the developer of the Hawkins Inc. site. This cost estimate includes a general estimate for the costs associated with supporting the existing Koch gas pipeline crossing located beneath the future railroad track extension at the southwest corner of the site, steel casing pipe beneath the future railroad tracks and a general estimate to remove and replace the existing bituminous access road where the sanitary sewer connection will be made. However, this estimate does not include the costs associated with relocating the existing utility poles and hydrants at the southwest corner of the site. This work must be completed by the developer prior to the installation of sanitary sewer facilities. If trunk sanitary sewer facilities are extended to the Feed Products North, Inc. site with the Hawkins site improvements, the costs associated with this sanitary sewer extension, less the steel casing costs, will be shared by owners of the Hawkins and the Feed Products North, Inc. site, and will be prorated to reflect the percentage of land area to be served by the sanitary sewer extension. Feasibility Report Hawkins Sanitary Sewer E.xterisiou City ofRoseniount Project No. 438 11'SB Project No. 1916 -46 Page 5 The area being developed by Hawkins, Inc. to be served by the sanitary sewer extension is 28.03- acres, or 52.6% of the total land area. The area owned by Feed Products North, Inc. to be served by the sanitary sewer extension is 25.25- acres, or 47.4% of the total land area. Therefore, the costs associated with the sanitary sewer extension that would be the responsibility of Hawkins, Inc. would be: $230,935 * 52.6% + $62,565 = $184,040 The costs associated with the sanitary sewer extension that would be the responsibility of Feed Products North, Inc. would be: $230,935* 47.4% _ $109,465 5. FEASIBILITY AND RECOMMENDATION The following improvements are recommended to be constructed as part of the Hawkins Sanitary Sewer Extension: • Construction of 8 -inch gravity sanitary sewer facilities within a 40 -foot to 60 -foot wide drainage and utility easement along the western and northern access drives proposed within the Hawkins site, • Construction of trunk sanitary sewer facilities from the existing manhole located near the southwest corner of the Hawkins site to the future building proposed within the Hawkins site that will accommodate anticipated peak wastewater flows of 310,050 gal /day. The total estimated cost to extend sanitary sewer facilities within the Hawkins site is $273,100. Proposed funding for this portion of the project is the responsibility of the developer. If sanitary sewer facilities are extended to the Feed Products North, Inc. site with the Hawkins site improvements, the total project costs are estimated to be $293,500. Hawkins, Inc. would be responsible for $184,040 of those total project costs, while Feed Products North, Inc. would be responsible for $109,465 of those total project costs. The project is feasible, necessary, and cost - effective from an engineering standpoint. It is our recommendation that the improvements be implemented as outlined in this report.
