EXECUTIVE SUMMARY � � City Project No. 387 consists of recor�structing County Road 38 (CR 38) (Bonaire Path) from Trunk Highway 3 (TH 3) east to the easterly tract line of the Harmony, formerly known as , Brockway,residential subdivision. The proposed improvements consist of right turn lanes, left turn lanes, sanitary sewer trunk and lateral mains,trunk and lateral watermains, storm sewer, , concrete curb and gutter, a retaining wall, and a bituminous path along the south side of the road along the entire length of the project. The existing pavement on CR 38 will berehabilitated by complete removal and replacement. , Dakota County has proposed to turn back ownership of CR 38 to the City of Rosemount. Consequently, additional discussions are being held with the County to make sure the funding ' for all street and associated storm sewer improvements along CR 38, as outlined in this report, are included in the tum-back agreement, or are provided for in the event that the turn-back does not occur prior to the start of construction. The City will also need to confirm adequate funding , to pay for their share of the improvements. The total estimated project cost for CR 38 is $1,5'77,300. Of this amount, approximately$76,400 , would be assessed to adjacent property owners on the north side of CR 38. Dakota County is expected to contribute funding for 55%of the roadway and associated storm sewer improvements to CR 38 in accordance with County funding policy. County contributions would / total an estimated$658,200. The remainder of the estimated $842,700 required in project funding would be contributed by the City of Rosemount through the City's Sanitary Sewer Core Fund, Watermain Core Fund, Storm Sewer Core Fund, Street Capital Improvement(CIl') Fund, 1 and previously deposited cash payrnents from the developer for the Harmony Development. It is proposed that construction would take place in 2005. This project is feasible,necessary, and ' cost-effective from an engineering standpoint, and should be constructed as proposed herein.

INTRODUCTION � 2.1 Authorization , On November 3, 2004 the Rosemount City Council authorized the preparation of an Engineering Feasibility Report for County Road 38 (Bonaire Path)(CR 38) Street and Utility Improvements. This project has been designated as City Project No. 393. � 2.2 Sco e P ' This project consists of the upgrading of existing CR 38 from TH 3 east approximately 2,250 feet to the easterly tract line of the Harmony Development. Utility improvements will consist of trunk and lateral sanitary sewer installation, trunk and lateral watermain installation, and storm , sewer installation. CR 38 is currently part of the Dakota County roadway system. Dakota.County is proposing to ' turn back ownership of CR 38 to the City of Rosemount. Since CR 38 is currently a county road, and is designated for the City's Municipal State Aid System, all proposed improvements must be designed to state aid standards. This improvement project is intended to upgrade CR 38 to , accommodate traffic volumes associated with the existing and projected development of the adj acent area. � A sanitary sewer trunk main is praposed for construction along CR 38 from Brockway Avenue west to TH 3, and will be stubbed north along the eastern ditch of TH 3 for future extension. A new sanitary sewer lateral main is proposed to extend to the east of Brockway Avenue,to ' provide future service to the existing properties north of CR 38. It is proposed that a lateral sanitary sewer line be jacked west under TH 3 to 132nd Street West,where a stub will be placed for future extension to service the area adjacent to Dodd Boulevard and 132°d Street West. , A trunk watermain is proposed along the entire length of the CR 38 improvements. It is proposed that the trunk watermain be jacked under TH 3 to provide local area service for future ' development to the northwest. The trunk watermain will also be stubbed north of the roadway area at TH 3 for future extension. , Storm sewer improvements are proposed to collect storm water runoff in accordance with Municipal State Aid standards and as necessary to meet the requirements of the Rosexnount Comprehensive Stormwater Management Plan. , .

GENERAL BACKGROUND � 3.1 Project Location , The project includes CR 38 from TH 3 east approximately 2,250 feet to the easterly tract line of . the Harmony Addition. , 3.2 Project History � This project was initiated as a result of the Brockway Development, and other continuing residential developments within the north-central portion of the City of Rosemount along CR 38. The area adjacent to CR 38 has been experieneing rapid development. The existing street section � is not adequate to accomxnodate the proposed traffic volumes and it is suggested that the street be upgraded to current urban roadway standards. The intersection of CR 38 and TH 3 also needs upgrading with turn lanes to improve intersection functions due to increasing traffic volume. A ' right turn lane on CR 38 at Brockway Avenue is a requirement of the Dakota County Highway Department and was a condition of the plat approval for the Harmony Development. � 3.4 Ezisting Conditions CR 38 is currently a rural two-lane paved street section. The existing pavement width on CR 38 � is approximately 25 -26 feet wide and is in very poor condition. There are two existing wetland areas located adjacent to CR 38. One is located along the south � side of CR 38, extending from approximately 300 feet to 400 feet east of TH 3. The other small wetland area is in the rear yard of an existing home directly north of CR 38 and east of TH 3. This wetland, and a small depression to the east of this wetland,has had a history of high water ' issues during the spring thaw and during large rainfall events. There are several e�cisting storm sewer culverts across or along CR 38. The storm water runoff ' flows in ditches or directly into existing closed depressions along the road, or into Keegan Lake. There are no existing sanitary sewer mains or watermains in CR 38. The adjoining residential and commercial properties utilize private septic systems and private wells. , I32nd Street W. at TH 3 is an existin avel road a roximately 25 -26 feet wide and is in poor g�' PP condition. West of TH 3,there are no public utilities servicing the area. � � � � ' City of Rosemount—Feasibility Report County Road 38(Bonaire Path) (Trunk Highway 3 to East Tract Line of Harmony) Street and Utiliry Improvemenis and Appurtenant Work ' City Project No.393 WSB Project No.I591-01 Page 4 , 4. TRAFFIC ANALYSIS � A traffic im act stud was r ared as lat for the Brockwa Glass p y p ep part of the prelunuiary p y property. The study concluded that TH 3 needs to be widened,turn lanes added at specific � intersections, including at CR 38, and traffic signals constructed at Connemara Tra.il and at CSAH 38 (McAndrews Road). The TH 3 improvements are being completed as a separate project, City Project No. 385, and are currently under conshuction. � The stud also determined that additional east-west road ca aci was r uired to continue the Y P tY � existinglevel of service as traffic increases in the area. CR 38 has been designated as one of the ' corridors that axe recommended for improvement. The report states that the projected average daily traffic(ADT)in the year 2025 is estimated at 2,000 vehicles per day. Due to this increase of vehicular traffic as a result of the Harmony Development and other developments at full build � out along the CR 38 comdor,the need for improving CR 38 to a 44-foot three-lane roadway was a recommendation of the report. The report also recommends that the traffic conditions be monitored at the CR 38 and TH 3 intersection to determine when a traffic signal system would � be warranted and justified. The proposed improvexnents to CR 38 regazding lane alignment and layout take into consideration a possible future signalized intersection at CR 38 and TH 3.

PROPOSED IMPROVEMENTS � 5.1 Surface Improvements 1 CR 38 is ro osed for com lete reconstruction as an urban section roadwa with B424 concrete P P P Y curb and gutter along a revised profile. The new road will be designed to meet State Aid ' Standards for a 40 mile per hour roadway. It is proposed to be 42 feet in width, and will include a 12-foot wide thru/right turn lane in each direction and a 14-foot wide center left turn lane. An additional right turn lane is also proposed for construction for eastbound CR 38 onto southbound ' Brockway Avenue. The pavement section will be designed for a 10-ton axle load and will consist of approximately 6 inches of bituminous pavement, 10 inches of Class 5 aggregate base, and 24 inches of select granular borrow. A retaining wall is proposed along the north side of CR I38 next to Keegan Lake. An eight-foot bituminous path is proposed for construction on the south side of CR 38. � Proposed street improvements can be found in Figure 2 and Figure 3 in Appendix A. Typical street sections can be found in Figure 4 in Appendix A. ' 5.2 Sanitary Sewer � An 18-inch PVC sanit sewer trunk main is ro osed for construction in CR 38 from the �5' P P intersection with Brockway Avenue west to TH 3,where it will be stubbed to the north along the , eastern TH 3 dra.inage ditch for future extension. An 8-inch PVC lateral main is proposed to be jacked west under TH 3 to 132nd Street West and then stubbed to the west to provide for future service to the area adjacent to Dodd Boulevard and 132nd Street West. An 8-inch PVC lateral � main is also proposed to extend east of Brockway Avenue to provide future service to the properties located to the north and east of the proposed street reconstruction. Sanitary sewer service stubs will be provided to the north at both intersections with 132nd Court for future � extension. These proposed improvements aze in accordance with the North Central Sanitary Sewer Study. , Proposed sanitary sewer improvements can be found in Figure 2 and Figure 3 in Appendix A. 5.3 Watermain � A 16-inch DIP trunk watermain is proposed for construction along the entire length of CR 38 and across TH 3 as part of this project. Eight-inch DIP stubs will be placed to the north at each ' intersection with 132nd Court W. for future extension. A 16-inch DIl'watermain will be stubbed to the north along the west side of TH 3 to provide for future service to the north. These proposed improvements are in accordance with the City's Comprehensive Water Plan. �. Proposed watermain improvexnents can be found in Figure 2 and Figure 3 in Appendix A.

Small storm sewer stub pipes will be constructed to the north to drain an existing pond area � in the northeast corner of Trunk Highway 3 (TH 3)and CR 38 and to drain an existing closed depression in the rear yard of one of the properties adjacent to the project. All storm sewers � would meet State Aid and Dakota County Standards and would be in accordance with the City of Rosemount's Comprehensive Stormwater Management Plan. � Proposed storm sewer improvements can be found in Figure 2 and Figure 3 in Appendix A. 5.5 Wetlands � The proposed project will impact an existing wetland area on the south side of CR 38, approximately 300 feet to appro�mately 400 feet east of TH 3. The anticipated impact is � approximately 11,560 square feet of existing wetland area that will be filled during the road widening and associated construction activities. The Harmony Development has received approval from the City of Rosemount as the Local Governing Unit to mitigate 4,036 square feet , of the wetland impacts created by the additional fill required for the right turn lane needed as part of the Harmony Development. The City of Rosemount will be required to mitigate the remaining 7,528 square feet of anticipated impacted wetland area.as part of the street and utility , improvement project. ' S.6 Right-of-Way/Easements - There will be some additional construction easement needs along the north side of CR 38 due to , slope encroachments.All required right-of-way and construction easements along the south side of CR 38 have been, or will be, dedicated by the Hannony Addition as part of the plat approval ' process. It is anticipated that 16,300 square feet of temporary construchon easements will be necessary for construction of the slopes along the north side of CR 38. A more accurate figure for the total ' temporary construction and permanent easement area required for construction will be determined during the final design phase of the project. � ' � ' � City of Rosemount-Feasibi[ity Report County Road 38(Bonaire Path) (Trunk Highway 3 to East Tract Line of Har�nony) Street and Utility Improvenients and Appurtenant Work � Ciry Project No.393 WSB Project No.I591-01 Page 7 ' 6.

Detailed assessment calculations can be found in Appendix D. ' 6.2.1 Dakota County , In accordance with Dakota County's cost participation policy,it is proposed that Dakota County will pay for 55%of the roadway and storm sewer systexn improvements on CR 38. The total Dakota County contribution is estimated at$658,200. � l�2.2 Harmony Development ' As a requirement of the plat approval for the Harmony Development along the south side of the proposed CR 38 improvements,the developer was required to submit a cash payment of$246,500 to pay for the costs of the roadway and access improvements. ' 6.2.3 Special Assessments Properties along the north side of CR 38 with direct access on to CR 38 will be assessed � on a per-unit basis. According to the City's 2005 Fee Resolution, for complete street reconstruction projects, a lump sum of$4,000 per unit will be assessed to benefiting properties. Five properties have direct access to CR 38,which brings the total street ' assessments for CR 38 to $20,000. Additional assessments are proposed for the installation of new sanitary sewer and ' watermain. These assessments are determined on a per-developable unit basis. Although there are five properties with access to CR 38, there is the potential for one of these properties to subdivide into two parcels,bringing the total developable units to six. Each ' developable unit is proposed to be assessed a total of$9,400 for sanitary sewer and water service. This rate is based on the average lateral sanitary sewer and watermain extension cost. Tota1 utility assessments are estimated at$56,400. , _ Tota1 special assessments are estimated at$76,400.. , 6.2.4 Sanitary Sewer Core Fund The City's Sanitary Sewer Core Fund is available to fund txunk sanitary sewer ' improvements throughout the.City of Rosexnount. For the CR 38 portion of the project, there is approximately$101,700 in estimated trunk sanitary sewer improvements. , ' ' , City of Rosemount—Feasibility Report County Road 38(Bonaire Path) (Trunk Highway 3 to East Tract Line of Flarmony) Street and Utility Improvements and Appurtenant Work ' Gity Project No.393 WSB Project No.1591-01 Page 9 ' 6.2.5 Watermain Core Fund , The City's Watermain Core Fund is available to fund any trunk watermain improvements ' throughout the City of Rosemount. Trunk watermain improvements along CR 38 total an estimated$208,400. , 6.2.6 Storm Sewer Core Fund The City's Storm Sewer Core Fund is available to fund major storm sewer and pond ' improvements throughout the City of Rosemount. For the CR 38 portion of the project, approximately 55%of the storm sewer costs will be paid for by Dakota County. The rexnaining 45% of the storm sewer, and 100%of the adjacent pond outlet improvements, ' are the responsibility of the City of Rosemount. The City storm sewer costs are estimated at$82,300.
