Attached please find a copy of the Feasibility Report for the GlenRose Addition Street and Utility Improvements and Appurtenant Work project. This report addresses the construction of street and utility improvements necessary for the development of the GlenRose Addition residential development located on the east side of TH 3 directly east of the Rosemount Community Center and west of Erickson Park. It also considers the extension of sanitary sewer and water service to existing properties located north of the development A brief review of the proposed improvements and funding is as follows. The proposed improvements include water main, sanitary sewer, storm sewer, concrete curb and gutter, and the addition of a right turn lane along TH 3. Additional improvements proposed to be completed as part of the GlenRose Addition include the extension of a bituminous trail from Erickson Park to the GlenRose Addition, the extension of trunk and lateral water main, as well as lateral sanitary sewer to existing properties, from the GlenRose Addition north to Connemara Trail. An existing property, located at 13930 South Robert Trail, has a failed septic system, and has previously requested that the City extend sanitary and water service to the non compliant property A second property, located at 13940 has also requested that the City extend sanitary and water service to the property. The total estimated project cost for the proposed GlenRose Addition and associated improvements is $1,488,800 Of this amount, the GlenRose Developer, Dean Johnson Homes, would contribute an estimated $1,292,700. An estimated $43,600 would be assessed to adjacent property owners along the east side of TH 3 benefiting from City water main and samtarc sewer unprovements. An estimated $94,600 would be contributed by the City of Rosemount through the City's Water Main Core Fund In order to install the proposed sanitary sewer and water main services to the GlenRose development, and extend sernces to existing properties, permanent utihty easements will need to be acquired The cost of these easements is estimated at $57,900, and has been included as part of the total project cost but not as part of the funding breakdown. The majority of the public improvements for the GlenRose Addition, mdudmg the first lift of bituminous pavement and all restoration items, are proposed to be completed m 2006.

EXECUTIVE SUMMARY City Project No. 397 consists of the installation of public streets and utilities for the proposed GlenRose Addition, located on the east side of Trunk Highway 3 (TH 3) directly east of the Rosemount Community Center and west of Erickson Park. The proposed improvements include water main, sanitary sewer, storm sewer, concrete curb and gutter, and the addition of a right turn lane along TH 3. Additional improvements proposed to be completed as part of the GlenRose Addition include the extension of a bituminous trail from Erickson Park to the GlenRose Addition, the extension of trunk and lateral water main, as well as lateral sanitary sewer to existing properties, from the GlenRose Addition north to Connemara Trail. An existing property, located at 13930 South Robert Trail, has a failed septic system, and has previously requested that the City extend sanitary and water service to the property. A second property, located at 13940, does not have a failed septic system, but has also requested that the City extend sanitary and water service to the property. The total estimated project cost for the proposed GlenRose Addition and associated improvements is $1,488,800. Of this amount, the GlenRose Developer, Dean Johnson Homes, would contribute an estimated $1,292,700. An estimated $43,600 would be assessed to adjacent property owners along the east side of TH 3 benefiting from City water main and sanitary sewer improvements. An estimated $94,600 would be contributed by the City of Rosemount through the City's Water Main Core Fund. In order to install the proposed sanitary sewer and water main services to the GlenRose development, and extend services to existing properties, permanent utility easements will need to be acquired. The cost of these easements is estimated at $57,900, and has been included as part of the above total costs. The majority of the public improvements for the GlenRose Addition, including the first lift of bituminous pavement and all restoration items, will be completed in 2006. The final Lift of bituminous and any associated clean up and restoration items will be completed in 2007. This project is feasible, necessary, and cost- effective from an engineering standpoint, and should be constructed as proposed herein.

INTRODUCTION 2.1 Authorization On June 21, 2005 the Rosemount City Council authorized the preparation of an Engineering Feasibility Report for the GlenRose Addition Street and Utility Improvements and Appurtenant Work project. This project has been designated as City Project No. 397. 2.2 Scope This report addresses the construction of street and utility improvements necessary for the development of the GlenRose Addition residential development located on the east side of TH 3 directly east of the Rosemount Community Center and west of Erickson Park. The proposed improvements include construction of streets, lateral sanitary sewer, a local sanitary sewer lift station, water main, and storm sewer systems. Lateral water main and lateral sanitary sewer would be extended from the GlenRose Addition north along TH 3 to Connemara Trail, thus servicing properties along the east side of TH 3 that are currently without City sanitary sewer and water service, as well as providing water main looping that is necessary to maintain fire flow requirements within the GlenRose Addition. Furthermore, trunk water main would be connected on the west side of TH 3 between the Rosemount Community Center and Connemara Trail, completing the trunk water main loop outlined in the City's Comprehensive Water Plan. Clearing and grubbing of trees and preliminary site grading will be completed privately prior to construction of the street and utility improvements. 2.3 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 Field Observations of the Area City of Rosemount Comprehensive Stormwater Management Plan Field Survey Preliminary Plat information for GlenRose Addition prepared by Loucks Associates, Inc.

GENERAL BACKGROUND 3.1 Project Location The project is a proposed 76 -unit townhouse development to be located on a 10.76 -acre parcel. on the east side of TH 3 directly east of the Rosemount Community Center, west of Erickson Park, and north of the St. Josephs Cemetery. To provide sanitary sewer and water main service to the GlenRose Addition, additional work will need to occur within the TH 3 right of way north of the GlenRose Addition to Connemara Trail. Trunk water main is proposed for installation along the west side of TH 3 from near the Community Center north to Connemara Trail, while lateral sanitary sewer and water main is proposed for installation along the eastem property line of those properties fronting TH 3 north of the GlenRose Addition. A map showing the location of the project can be found in Figure 1 and Figure 2 of Appendix A. 3.2 Existing Conditions Currently, the area consists of both wooded and open areas, mainly covered with moderately sized trees and smaller brush. There is a delineated wetland located within the property, which will serve as a conveyance for storm sewer overflow once the property is developed. The developer will be clearing trees and grading the site prior to the final design of the proposed improvements. There is currently a private driveway that accesses the GlenRose property from TH 3. Due to the topography, temporary and permanent access will be obtained off of TH 3, approximately 1,200 feet south of Connemara Trail, slightly north of the existing driveway, and directly across from the south driveway to the Rosemount Community Center. The terrain in the project area is generally sloped to the east, toward Erickson Pond within Erickson Park. Storm sewer installed as part of the Rosemount Community Center project exists along the north property line and crosses the northeast corner of the property, and provides an outlet to Erickson Pond for the drainage pond located adjacent to the Community Center parking lot west of TH 3. There is currently no water or sanitary sewer service to the GlenRose Addition property. Lateral sanitary sewer installed as part of the Rosemount Community Center project exists along the east property line of the properties fronting TH 3, approximately 250 feet east of TH 3. This sanitary sewer runs from approximately 600 feet north of the GlenRose Addition north to Connemara Trail, and services three of the five properties located north of the GlenRose Addition Of the remaining two properties (13930 and 13940 South Robert Trail), the property at 13930 South Robert Trail has a failed septic system. The property owners of both properties have requested that City sanitary and water service be extended to service their parcels. City of Rosemount Feasibility Report GlenRose Addition Street and Utility Improvements and Appurtenant Work City Project No. 397 WSB Project No. 1556 -43 Page 3 A 12 -inch trunk water main currently runs along the east side of TH 3 in front of the Rosemount Community Center, but ends approximately 800 feet south of Connemara Trail, where a stub was previously installed for future connection to the existing 12-inch water main. The Rosemount Woods mobile home neighborhood, which is to the north of the GlenRose Addition, has existing water service via a private water main network, and as such, is not a feasible alternative for providing water service to the GlenRose Addition. There are overhead (aerial) private utilities located in the northwest comer of the proposed GlenRose Addition. These utilities service an existing building on the property, and will be removed by the property developer prior to preparation of final plans. 4. PROPOSED IMPROVEMENTS 4.1 Surface Improvements As part of this project, a City street will be constructed to provide access to the 76 proposed townhouse properties located within the GlenRose Addition. 140 Circle will be approximately 620 feet in length and end in a cul -de -sac. The street is proposed to be constructed to a width of 32 feet face -to -face with B618 concrete curb and gutter. The pavement section will be designed to accommodate a 7 -ton axle load, and will consist of approximately four inches of bituminous and six inches of Class V aggregate base, over a sand base with a minimum depth of two feet. As part of this project, private streets will also be constructed. It has been City of Rosemount policy to construct all private streets in new developments if public utilities are to be included within these streets as part of the overall development project. Pnvate streets and driveways will vary in width between 20 feet and 28 feet face -to -face with modified `S' (surmountable) concrete curb and gutter. Right and left turn lanes will be constructed for access to TH 3. The pavement section will be designed to accommodate a 5 -ton axle load, and will consist of approximately four inches of bituminous and six inches of Class V aggregate base, over a sand base with a minimum depth of one foot. Additionally, a right turn lane from northbound TH 3 to 140 Circle will need to be constructed. This turn lane will be approximately 300 feet in length, and will be designed to Minnesota Department of Transportation (Mn\DOT) standards to match the existing section of TH 3, with approximately eight inches of bituminous, 12 inches of Class V aggregate base, over a sand base with a minimum depth of two feet. Figure 3 in Appendix shows the location of the proposed street and surface improvements for the GlenRose Addition. City of Rosemount Feasibility Report GlenRose Addition Street and Utility Improvements and Appurtenant Work City Project No. 397 WSB Project No. 1556-43 Page 4 4.2 Storm Sewer The proposed storm sewer improvements include the construction of lateral storm sewer to serve the GlenRose Addition. The site storm sewer system will be designed for a 10 -year rainfall event. Stormwater will be routed in a manner consistent with Rosemount's Comprehensive Storm Water Management Plan (CSMP). The proposed improvements will route all of the site stormwater to a new stormwater management pond being constructed by the property developer in the south central portion of the property, adjacent to an existing wetland. From this new pond, an overflow Swale will be constructed to direct treated water into the existing wetland, where an emergency overflow outlet control structure will connect into an existing storm sewer pipe to the east and eventually flow into Erickson Pond (EP-P1770). Figure 3 in Appendix A shows the location of the proposed storm sewer installation for the GlenRose Addition. 4.3 Sanitary Sewer Due to the topography of the area, sanitary sewer service for the GlenRose Addition can only be obtained through the installation of lateral service pipes and a local sanitary sewer lift station. The proposed lift station will need to be installed in the northeast corner of the property at the east end of 140 Circle, with a force main extending west where it will connect to a proposed fl- inch PVC sanitary sewer. As previously mentioned, three properties have received sanitary sewer stubs from a previous sanitary sewer installation project. The property owners of the two remaining parcels without sanitary sewer service have requested that City sanitary sewer and water service be extended to their properties. In order to provide gravity sanitary sewer to these parcels, it is necessary to run the sanitary sewer along the east property line of these two properties, due in part to existing topography and due to the location of their existing septic systems. As such, an 8 -inch sanitary sewer would run along the eastem property line of the private properties located north of the GlenRose Addition, approximately 300 east of TH 3, north approximately 650 feet, where it will connect into an existing sanitary sewer manhole. Sanitary sewer service stubs would be extended for two existing properties along the east side of TH 3 north of the GlenRose Addition, as well as for the buildings located within the GlenRose Addition. Figure 2 and Figure 3 in Appendix A shows the location of the proposed sanitary sewer for the GlenRose Addition. City of Rosemount Feasibility Report GlenRose Addition Street and Utility Improvements and Appurtenant Work City Project No. 397 WSB Project No. 155643 Page 5 4.4 Water Main Water service for the GlenRose Addition can be obtained by installing 8 -inch ductile iron pipe (DIP) from an existing 12 -inch DIP water main located on the west side of TH 3 into the GlenRose Addition. To do this, the new water main will need to be installed in a steel casing to be jacked under TH 3. In order to provide water service to adjacent properties located north of the GlenRose Addition, the 8 -inch DIP will be jacked across TH 3 north of the Rosemount Community Center, and will run east to the eastern edge of the adjacent properties, and then south to the GlenRose Addition. One -inch copper water service stubs will be provided for each of the five properties north of the GlenRose Addition, and 4 -inch DIP water service stubs will be provided for each building within the GlenRose Addition. Fire hydrants will be installed within the GlenRose addition in accordance with City Standards. In order to provide adequate fire protection to the GlenRose Addition, the 8 -inch DIP water main needs to be looped to another point within the existing City of Rosemount water main network. Due to the location of the development, only two options exist for water main looping. The first option (herein referred to as Alternate 1) is to connect back into the 12 -inch trunk water main located on the west side of TH 3. The second option (herein referred to as Alternate 2) is to connect to an existing 8 -inch water main located along Brazil Avenue, east of Erickson Park. Alternate 1 requires a second water main jacking across TH 3, while Alternate 2 would require additional tree removal and restoration along the north property line of Erickson Park. Both Alternates provide equal benefit, so the deciding factor is the cost of the improvement. Detailed cost estimates can be found in Appendix B of this report, and are summarized in the Financing section of this report. Finally, a 12 -inch trunk water main is proposed for extension from near the Rosemount Community Center north to Connemara Trail along the west side of TH 3. The extension of this trunk water main is in accordance with the City of Rosemount Comprehensive Water Plan. It is anticipated that the trunk water main, while installed in the TH 3 ditch, may require temporary lane shifts on TH 3 to provide adequate staging areas for the water main installation activities. There is no impact anticipated to occur on the adjacent Rosemount Lutheran Cemetery property. Figure 2 in AppendixA shows the location of the proposed water main for the GlenRose Addition. 4.5 Private Utilities /Streetlights Xcel Energy will provide electrical service to the development area, phone service will be provided by Frontier Communications, and gas service by Aquila. Streetlights for the development will be incorporated into the private portion of the project and paid for by the developer. Overhead utility lines exist within the northwestern portion of the development. As previously mentioned, these utility lines will be removed by the private developer prior to construction of the proposed improvements outlined in this report. City of Rosemount Feasibility Report GlenRose Addition Street and Utility Improvements and Appurtenant Work City Project No. 397 WSB Project No. 155643 Page 6 Underground utilities exist on both the east and west side of TH 3, and include, but are not limited to, telephone, cable television, gas, and aviation communications. The majonty of these utility lines are anticipated to remain in -place during construction. There is the potential for approximately 400 feet of utility relocation as a result of the proposed right turn lane being installed along the east side of TH 3 for the GlenRose Addition. 4.6 Sidewalks/Trails An 8 -foot wide bituminous trail is proposed to run from the eastern end of 140 Circle into Erickson Park, connecting with an existing bituminous trail located adjacent to Enckson Pond within the park. In addition, 5 -food wide concrete sidewalks will be installed along the north side of 140 Circle and in locations within the development to provide pedestrian access to Erickson Park. Figure 2 in Appendix A shows the location of the proposed sidewalks and trails within the GlenRose Addition. 4.7 Permits /Approvals The anticipated permits and approvals that will be required and the respective regulatory agencies are fisted below: Minnesota Department of Health (MDH) Water main Minnesota Department of Transportation (Mn\DOT) Access/Work within R.O.W. Minnesota Pollution Control Agency (MPCA) Sanitary Sewer Metropolitan Council Environmental Services (MCES) Sanitary Sewer Minnesota Pollution Control Agency (MPCA).. National Pollutant Discharge Elimination System (NPDES) General Storm -water Permit for Construction Activity (MN R100001) The final plat requires approval by the Dakota County Plat Commission and Board of Commissioners.

In order to install water main and sanitary sewer service to the GlenRose Addition and the adjacent properties north of the GlenRose Addition, permanent utility and temporary construction easements need to be acquired from adjacent property owners. Total easement acquisition is estimated at 35,150 square feet. At $2.00 per square foot for permanent easement, and $1.00 per square foot for temporary construction easement, this totals approximately $57,900 in easement acquisition costs. This estimate is based on previous easement acquisition cost, and can vary based on easement use and cooperation with adjacent property owners. Easements will need to be acquired from the following properties: Prior to final design, negotiations for acquisition of permanent and construction easements will take place. It is anticipated that since easements are being requested primarily from property owners who have specifically requested the improvements, the Eminent Domain process will not be necessary. Funding for easement acquisition is detailed in the Financing section of this report.

FL \DANCING 5.1 Opinion of Cost Detailed opinions of cost can be found in Appendix B of this report. The opinions incorporate estimated 2006 construction costs and include a 10% contingency and 30% for all related indirect costs (legal, administrative, engineering, and financing items). Once all contingencies and indirect costs have been calculated, easement acquisition costs were added. The opinion of cost for the GlenRose Addition has been broken down into various schedules in order to facilitate funding calculations. The breakdowns include GlenRose Addition improvements (including both water main alternates), lateral sanitary sewer and water main improvements, and trunk water main improvements. Table 1 and Table 2 summarizes the proposed improvement cost for the GlenRose Addition comparing water main Alternate 1 and Alternate 2, respectively: City of Rosemount Feasibility Report GlenRose Addition Street and Utility Improvements and Appurtenant Work City Project No. 397 WSB Project No. 1556-43 Page 9 Table 3: Total Cost Summary GlenRose Addition, Altemate #1 $1,305,500.00 TH 3 Lateral Improvements $88,700.00 TH 3 Trunk Water Main Improvements $94,600.00 Easement Acquisition (Estimated) $57,900.00 GRAND TOTAL $1,488,800.00 As shown, Alternate 1 (2 °d water main jacking) provides a cost savings over Alternate 2 (water main through Erickson Park) of an estimated $25,100, or 2% of the total cost. As such, Alternate 1 is recommended for construction. Table 3 provides a total cost sun for all proposed GlenRose Addition, lateral sanitary sewer and water main improvements, and trunk water main improvements: 5.2 Funding Financing for this project will come from a combination of developer funds (Dean Johnson Homes), City of Rosemount Water Main Core Funds, and property assessments. Detailed assessment calculations and cost distributions can be found in Appendix C. 5.2.1 Dean Johnson Homes The GlenRose Addition property developer, Dean Johnson Homes, is anticipated to pay for all improvements within the GlenRose Addition, as well as for prorated portions of water main and lateral sanitary sewer improvements. Schedules A D include surface, sanitary sewer, water main, and storm sewer improvements that are located within the GlenRose Addition, with a base cost estimated at $1,270,100. Additionally, in order to provide sanitary sewer service to the GlenRose Addition, lateral sanitary sewer needs to be extended from the north. Funding for this sanitary sewer (and associated easement acquisition) is prorated to benefiting properties. There are two existing properties along TH 3, in addition to the proposed 76 properties that would benefit from sanitary sewer extension. As such, the cost share for the GlenRose Addition is $22,600 for sanitary sewer improvements. Total contributions from Dean Johnson Homes are estimated at $1,292,700, or roughly $17,000 per property. 5.2.2 Water Main Core Fund The City's Water Main Core Fund is available to fund any trunk water main improvements throughout the City of Rosemount. Trunk water main improvements for the GlenRose Addition and associated improvements include extension of the aforementioned 12 -inch trunk water main along the west side of TH 3, as well as providing lateral water service across TH 3 to the GlenRose Addition and adjacent properties. Total trunk water main costs are estimated at $94,600. City of Rosemount Feasibility Report GlenRose Addition Street and Utility Improvements and Appurtenant Work City Project No. 397 WSB Project No. 1556 -43 Page 10 5.2.3 Special Assessments Special property assessments are levied against properties within the City of Rosemount where a public improvement, such as utility extensions or street improvements, will increase the property value of that property. Of the five properties immediately adjacent to the GlenRose Addition, three properties currently have sanitary sewer service, and none of the properties have water service. For the two properties receiving sanitary sewer service, the prorated assessment for the sanitary sewer improvements associated with the GlenRose Addition are estimated at $3,700 per property. Lateral water main improvements are divided evenly among the five properties that would receive water service. Water main assessments are estimated at $7,240 per property. Total special assessments are estimated at $43,600. A preliminary assessment roll can be found in Appendix C. 5.2.4 Easement Acquisition As previously indicated, there will be a need to acquire approximately 35,140 square feet in permanent and temporary construction easements in order to construct the lateral sanitary sewer and water main along properties fronting TH 3. Since easements will be acquired strictly for lateral sanitary sewer and water main improvements from properties that would benefit from the proposed improvements, the costs for easements not dedicated to the City will be assessed back to adjacent properties. Assuming no easements are dedicated without compensation, the estimated cost for easement acquisition is $57,900.
