The work session will provide updates to several projects and the financial implications each has for the City. History The City uses the Capital Improvement Program to schedule projects. The City coordinates these projects with Scott County, Savage, SMSC and MNDOT. Current Circumstances Several projects are currently under development. These projects include:  CSAH 83 (Between Wilds Parkway and CSAH 81)  CSAH 81 (Stemmer Ridge Road)  CSAH 42 and TH 13 Intersection  Manitou Road / Raspberry Ridge Road CSAH 83 – Scott County in coordination with the Shakopee Mdewakanton Sioux Community (SMSC) and the City of Prior Lake are planning for improvements to CSAH 83 from Wilds Parkway to CSAH 82. The SMSC business enterprises are beginning construction of an event center which will bring additional traffic to this roadway corridor. The nature of the event traffic will bring additional traffic at specific times. Additional roadway capacity is needed to handle this traffic. The existing traffic volumes are already high due to vehicle trips to and from the casino enterprises. This segment of roadway is also very narrow near Mystic Lake. The proposed project will add an additional through lane on CSAH 83 as well as an exit ramp to the SMSC business enterprises. Additional turn lanes and modification to intersections along the corridor will be part of the project as well. In order to widen CSAH 83 through this area, soil placement is needed in wetland areas and Mystic Lake. Scott County is currently working through environmental permitting for this project. This project is scheduled to begin in 2016 with most of the work occurring in 2017. Once completed, internal circulation within the business enterprise area will be converted to “one way” 2 travel. Additional information regarding this project will be provided and an informational meeting will be conducted in the first quarter of 2016. As roadway volumes increase it becomes more and more difficult for vehicles to make left turns out of the Stonecrest Path neighborhood and Wilds Parkway during peak times. While the full access at this intersection is not scheduled to be changed with this project, frustration levels will increase at this intersection for those wishing to facilitate a left turn movement. The Stonecrest Path neighborhood is further complicated by the fact that no other access is provided out of this neighborhood. Improved sightlines and pedestrian trail are proposed with this project which will aid in navigation and pedestrian connectivity. City Staff have provided comments (attached) to Scott County regarding concerns with growing traffic volumes on these two neighborhoods. City Councilors should provide feedback tonight if they have concerns. The total cost of this project is preliminarily estimated to be $20,000,000. The City’s contribution is not expected to be substantial. The current CIP estimates $100,000 for the City contribution, but an amount less than that can be expected. CSAH 81 (Stemmer Ridge Road) – Scott County in coordination with the SMSC has also begun development of a project to construct CSAH 81 from Stemmer Ridge Road to CSAH 82. This roadway would provide a critical link between CSAH 12 and CSAH 82 to support the CSAH 17 corridor and provide the permanent access to Spring Lake Regional Park. This project was originally programmed by the City for completion as Stemmer Ridge Road. As talks stalled between the City of Prior Lake and the SMSC, Scott County has begun to work with the SMSC for completion of this roadway. For tonight, the focus will be on the design and not the process by which the City, SMSC, and County coordinate these improvements. During discussions with the Stemmer Ridge Neighborhood, concerns were raised regarding future traffic volumes, future traffic speeds, future casino traffic, and pedestrian crossings. The design incorporates several elements to reduce speeds and discourage the use of this roadway as a replacement to CSAH 17. 1. Center Median to Divide Travel Lanes 2. Roundabout at Spring Lake Entrance 3. Curvilinear Design 4. Design Speed of 35 mph 5. Pedestrian Trail/Sidewalk on Both Sides of Street 6. Pedestrian Crossing at Roundabout 7. No Direct Driveway Access to Roadway The design also contemplates the City utility installation within the corridor. Again, the discussion should be focused on the design aspect and not the process, but Scott County may be the coordinating agency for the completion of the project. For now it is assumed that City contributions to this project 3 would follow the City’s Capital Improvement Plan which calls for Prior Lake contribution of $2,000,000 for this $5,000,000 project. The City’s share is planned to come from the Street Oversizing Fund and the Trunk Fund and not City Tax Levy. CSAH 42 and TH 13 – Scott County in Coordination with MNDOT, Savage and Prior Lake are once again beginning discussions regarding improvements to the CSAH 42 and TH 13 intersection. This intersection has been operating using a “temporary signal” for over a decade. This project is scheduled to possibly begin in 2017, but most work would occur in 2018. Property acquisition is a long process and therefore design work is starting now to provide the limits of right of way for purchase by the County. The improvement project would widen CSAH 42 approaches to TH 13 with additional lanes. Not much work is scheduled for Highway 13 as the necessary lanes are already in place. This project may not be the final ultimate project design as a third through lane may be needed in the future. This intersection project is being designed so that future widening for the additional through lanes would occur to the north with minimal impact to existing pavements. The project will also revise access points along CSAH 42 with changes to the concrete median. The access to Harbor Place is scheduled to be reduced from a full access to a right in / right out access. As traffic volumes grow, it is difficult to retain this full access due to its close proximity to the signalized access at Rutgers Street as it interferes with the left turn lane. The County may explore an alternative which builds a connection between Harbor Place and Rutgers Street. The Commerce Avenue access is also proposed to be modified to a right in / right out. The City has decided that a connection between Commerce and Rutgers is not something which the City is interested in pursuing. However, Scott County may choose to explore that connection further. As an addition to the project, a trail segment could be constructed between Boudin Street and Highway 13. The terrain for this segment of trail is set up for the trail construction quite well. The cost for this addition is estimated to be $75,000 funded by the City if it is desired. It is anticipated to cost more as a standalone project if the City decides not to complete this work with the CSAH 42 and TH 13 project. The total cost of this project is preliminarily estimated to be $12,700,000. The City’s contribution is estimated at $300,000 without adding the trail along Highway 13. With the addition of the trail, the City cost is estimated at $375,000. Construction of that trail is consistent with the incremental trail work included in the TH 13 and 150th Street intersection project. As a part of the total city cost, the current CIP estimates $100,000 for utility repairs in the area. Manitou Road / Raspberry Ridge Reconstruction – At the last City Council meeting the feasibility report for the Manitou Road/Raspberry Ridge Reconstruction project was discussed. At that meeting the City Council 4 requested that Staff explore two additional options which would entail less construction and less cost. Attached to this agenda report is a Memo which explores these additional options and provides a comparison table for all the options. Option A which was studied in the feasibility report included reconstruction of Manitou Road and the Raspberry Ridge neighborhood. This option also included the replacement of watermain pipe and the lining of the trunk sanitary sewer pipe. Option B which was studied in the feasibility report included reconstruction of Manitou Road and rehabilitation of the Raspberry Ridge neighborhood. The watermain was proposed to be lined with this option. The trunk sanitary sewer pipe was also proposed to be lined with this option. Option C examines the costs for completion of reconstruction of Manitou Road as well as reconstruction of those portions of the Raspberry Ridge neighborhood which include the 16” watermain. Option D examines the costs for reconstruction of Manitou Road only and lining of the 16” watermain within the Raspberry Ridge neighborhood. City Staff have also prepared an Option E which examines the cost of simply completing Manitou Road without lining the watermain. It would be recommended with this option to replace certain water valves within the Raspberry Ridge Neighborhood which are leaking as a result of corrosion. Some of the options shown provide for lining of a 15” trunk sanitary sewer pipe. Televising of this line revealed that infiltration was occurring which resulted in mineral deposits within the sewer pipe. Left unchecked these deposits can cause backups within the pipe. Our knowledge of this condition now without taking action could affect the outcome of future claims. The water which is infiltrating the pipe also adds to the wastewater and ultimately flows to the Blue Lake Wastewater Treatment Facility. The cost to line this segment of pipe is estimated to be $505,000. This has a $0.75 impact to sanitary sewer rates. An interim alternative would be to break apart the mineral deposits within the pipe now and program the lining work for a future year. In discussions with the Finance Department it may be more appropriate to bond for the sanitary sewer repairs like these instead of paying the cost for the work out of the sanitary sewer fund. This strategy could also be used for water improvements as well. This would help moderate rate increases but would also introduce cost related to interest. This is a bigger discussion which is outside the scope and time limits of this work session. As a part of the discussion of options for Raspberry Ridge, impact of this project on the 2017 levy should be considered. 5 The costs and tax levy impact for 2016 projects are shown in the attached table below: Project CIP Project Cost CIP Project Tax Levy CIP Tax Levy Impact for 2017 Revised Project Cost Revised Project Tax Levy Revised Tax Levy Impact for 2017 150th Street (Additional Funding) $450,000 $450,000 0.45% $450,000 $450,000 0.45% Rolling Oaks $890,000 $0 0.00% $890,000 $0 0% Stemmer Ridge Road $2,000,000 $0 0.00% $2,000,000 $0 0% Duluth Avenue $1,181,560 $774,020 0.75% $0 $0 0% Manitou Road $1,550,000 $750,000 0.75% $2,363,316 $783,097 0.78% Appaloosa Trail / Highland Ct $120,000 $120,000 0.01% $90,000 $90,000 0.01% Raspberry Ridge/Timberglade $2,375,000 $975,000 0.97% $1,881,266 $491,871 0.49% Total 2.93% 1.73% The tax levy for these projects would impact the debt service starting in 2017 and affect the 2017 levy. Other tax levy pressures are discussed in a report to the City Council related the 2016 city budget. Tonight the City Council should be prepared for the following:  Offer feedback to Scott County regarding the CSAH 83 project design.  Offer feedback to Scott County regarding the CSAH 81 (Stemmer Ridge Road) project design.  Offer feedback to Scott County regarding the CSAH 42 and Highway 13 project design.  Offer feedback on whether to build trail on Highway 13 from CSAH 42 to Boudin Street.  Offer feedback to City Staff regarding Options for Manitou Road/Raspberry Ridge Reconstruction project.
