TRN15-000003. DISCUSSION: Introduction The purpose of this agenda item is to discuss the TH13 / Duluth Avenue Improvement Project for consideration of a resolution authorizing the City Engineer and City Attorney to acquire easements for the TH 13/Duluth Avenue Project, City Project No. TRN15-000003. History The City uses the Capital Improvement Program to schedule projects. In this case the intersection of TH 13 and Duluth Avenue has been identified for several years and is shown in the 2016-2020 Capital Improvement Program. MNDOT has also been planning for the signal replacement at Highway 13 and Duluth Avenue for several years. Duluth Avenue approaches to the signal could be better configured to improve operation of the signal. This project would reconstruct portions of Duluth Avenue to better align with the signal system. Dedicated lane configurations (raised medians) could be adjusted for better signal efficiency. Access points on Duluth Avenue are in close proximity to the intersection and are affecting operations. On September 8, 2014, the City approved a professional services contract with WSB &Associates for the Duluth Avenue Intersection Project. A portion of the work includes the preparation of a feasibility report. At the January 26, 2015, City Council meeting, the City Council approved concept 2 for construction with no median north of TH 13. At the February 9th City Council work session, the City discussed the financing of all City projects for construction in 2015. The costs associated with these projects have an impact on the tax levy. Considering the high costs the City Council directed staff to review the possibility of reducing the scope of the Duluth Avenue project and the impacts of a scope reduction. Phone 952.447.9800 / Fax 952.447.4245/www.cityofpriorlake.com On February 231, the City Council reviewed a report which discussed design modifications to reduce the scope of the project. The agenda report is attached. The outcome of this meeting was to shift the project from construction in summer of 2015 to summer of 2016, however the City continued to complete the design and start the right of way acquisition process. Current Circumstances The Feasibility Report discusses the operation of the Duluth and TH 13 signal. Currently the signal operates at a Level of Service (LOS) C (On a scale of A-F) and has experienced three crashes in the last four years. LOS C means that the intersection is beginning to feel more restricted and queues develop behind turning movements. The intersection operation is projected to degrade to a LOS F in the next four years. Level of Service F means that vehicle demand exceeds the capacity of the intersection. Additionally, Holiday Station Stores has communicated that the store located at Duluth and TH 13 is a top 5 producing store of 500 for their company. Considering the continued growth of traffic, anticipated degradation of this intersection, and current availability of MNDOT funding, it appears that now is the appropriate time for completion of this project. Right of Way In order to deliver this project in the summer of 2016, the City must continue the right of way acquisition process. The City is authorized to acquire real estate which is needed for public use. In furtherance of the project, the City will need to acquire permanent right-of-way easements and temporary construction easements from certain parcels of real property located in the City. Pursuant to statutory requirements, the City Attorney retained Patchin Messner Dodd & Brumm to perform appraisals on the impacted parcels. The appraisals provide a valuation for the easements to be obtained. Attached is a spreadsheet designating the values of the easements to be acquired for the project. Medians At the January 26th, 2015 City Council meeting the City Council discussed the medians on Duluth Avenue. The City Council directed that the median be extended across the Holiday north entrance and eliminate the median on the north side of the project at Anna Trail. Since the February meeting, the design incorporated these changes. MNDOT has reviewed the removal of the north median at Anna Trail and insists that it is necessary for proper signal operations. MNDOT's concern is that queuing on Duluth at TH 13 will restrict left turning movements from northbound Duluth. Vehicles turning left onto Anna Trail will back up traffic onto TH 13 while they wait for an opening. MNDOT points out that vehicles wishing to turn left into the Anna Trail neighborhood can make the left turn movement one block north as Anna Trail intersects Duluth in two areas. Holiday has expressed significant concerns over the median extension across their north entrance. The City has been meeting with Holiday to 2 design a solution which meets the City's needs and the needs of Holiday. One resolution may be to move Holiday's north access approximately 25 feet south to allow for greater separation from TH 13 and the Village Lake Mall entrance. MNDOT has approved this revised design. This design eliminates approximately 40 feet of median on the south side of the project. Cost Saving Measures During the Capital Improvement Program deliberations, the City Council directed staff to review the Duluth Avenue Project again for cost saving measures. The scope of this project to improve this intersection includes widening of Duluth Avenue for better signal operations. The design already includes preservation of 2410 square yards of pavement which instead of being removed and replaced will be saved and an overlay placed over the existing pavement. This approached saved approximately $60,000 over complete reconstruction. The project limits have already been minimized to reduce the length and footprint of the project. The project also reduced impacts to TH 13 as lane configurations on TH 13 are sufficient for optimal signal operation and will remain the same. While pavement widening was necessary for signal operations, additional pedestrian facilities were added to enhance walkability within this region. These items as well as some other minor modifications could be removed from the design to provide a modest reduction in price. If the project is completed, this intersection is expected to serve our community for at least 20 years in the present configuration. The city council may wish to consider this fact as it contemplates the savings outlined below. These items are listed below: Item Impact Savings Eliminate Sidewalk North Pedestrians crossing TH 13 to $17,000 of TH 13 and East of walk from the Wells Fargo site Duluth would need to cross Duluth to then cross TH 13. No pedestrian facilities would be available to serve Subway. Eliminate Sidewalk along No pedestrian facilities would be $5,500 Holiday Site available to serve Holiday. Reduce Median on South Left turn movements out of $3,000 Leg by 40 feet Holiday may occur. No Concrete Medians - Left turn movements may still $21,000 Paint Medians Instead of occur reducing the effectiveness Concrete Median Barriers of the signal improvements. Completing the concrete medians at a later date will result in higher costs due to remobilization. 3 Village Lake Drive and Duluth Avenue During the course of the design, local businesses have expressed concern over the operation of Village Lake Drive at Duluth once the project is complete. Because the left turn movement from Duluth Avenue to the mall entrance near TH 13 is restricted, those cars must navigate to Village Lake Drive to access the mall area. The attached report explores the implications of this project on the operations at Duluth Avenue and Village Lake Drive. While the level of service of this intersection remains at LOS A after the project, queues will develop on Duluth Avenue at Village Lake Drive due to the platooning effect of cars releasing from the traffic signal at TH 13. The report explores options to alleviate the queuing on Duluth. The recommended option is to provide a right turn lane on Duluth at Village Lake Drive. This would allow a dedicated lane for the predominant right turn movement onto Village Lake Drive. The cost for this option is $90,000. Considering the inertia of completing the Duluth intersection project, if the City Council is inclined to build the right turn lane, it is recommended this work be completed with the Duluth/1-H 13 intersection project. Conclusion It is recommended that the City Council proceed with this project including the completion of the work at Village Lake Drive and Duluth. It is also recommended that the City Council approve the appraisal values of the easements and authorize the City Engineer and City Attorney to acquire the easements by negotiation or eminent domain proceedings. The project construction schedule contemplates that work will begin on this project in the summer of 2016. It is necessary for the City to have title and possession to the easements before the construction contracts are awarded. ISSUES: The tax levy impacts of capital improvement projects continues to be a concern for the City Council and the community. The City Council may be inclined to eliminate this project from the capital program for 2016. If the City Council elects to remove this project, MNDOT would re-assign the funds to another project. Because of how MNDOT plans their projects, they may not have funding for improvements at this intersection until after 2020. In the future MNDOT may elect to simply replace the signal and charge the City for our half ($207,540). If after this signal replacement, the City desires to widen Duluth Avenue for better operations on our local street system, MNDOT would not participate in the cost to re-build the traffic signal. As indicated in the feasibility report, the current level of service of this intersection is LOS C. Utilizing a growth factor, the intersection moves to a LOS F within four years. If the City were to wait an additional 4 years to complete the improvements it is projected to cost an additional $150,000 considering construction cost index. Unless something changes, MNDOT has communicated that they would not have funds available to participate in this project until after 2020. In other words, the City would need to pick up MNDOT's portion of the signal ($207,540) if the Council desires to complete the project in 2019 or if MNDOT funding isn't available when the City desires completion of the project. 4 The City has expended $150,000 to date for the feasibility study, design, appraisals, and soil exploration. If the City Council decides to abandon this project the City would be unable to use bonding or state aid funds to pay these costs. General fund reserves or tax levy would need to be utilized to fund these expenditures. Because bonding would not be appropriate to pay these current expenditures, these costs would not be spread out over a ten year period and may impact the 2016 or 2017 tax levy amount. FINANCIAL The preliminary cost estimate is provided below: IMPACT: COSTS Construction $941,177 Right of Way $84,550 Project Support Costs $214,550 Total $1,240,277 *Costs do not include work at Village Lake Drive and Duluth Ave. ($90,000) The funding table below shows how the project would be financed: FUNDING MNDOT $207,540 City MSA $200,000 Tax Levy (Bonded $832,737 over 10 years) Total $1,240,2777 The Duluth Signal project is proposed to be financed by MNDOT, MSA and Tax Levy. The costs include construction estimates for each construction element, project support costs and right of way costs. A project contingency is also included in these preliminary numbers.

This report will document the existing conditions and operations at the intersection and analyze several alternative geometries and traffic control configurations. EXISTING CONDITIONS The existing conditions at Duluth Avenue and Village Lake Drive consist of a through-stop intersection with a stop sign on Duluth Avenue and through traffic on Village Lake Drive. The north approach has a shared left/right-turn lane. The east approach has separate through and right-turn lanes while the west approach has separate through and left-turn lanes. Village Lake Drive also has a shared left-turn lane preceding the intersection on both sides. The intersection is 420 feet south of the signalized Trunk Highway(TH) 13 and Duluth Avenue intersection. The existing condition can be viewed in Figure 1 in Appendix A. The southbound Duluth Avenue approach at Village Lake Drive currently experiences queueing problems from the platooning effect of vehicles released from the traffic signal at TH 13 and Duluth Avenue. Queues backing up on Duluth Avenue block driveways for vehicles entering and exiting businesses causing further delay and frustration. PROJECT DESCRIPTION In an effort to relieve queueing issues and operational concerns at the intersection of Duluth Avenue and Village Lake Drive, several alternative geometric and traffic control configurations along with the proposed improvements at the intersection of TH 13 and Duluth were analyzed. Below is a list of alternative options evaluated for their capacity to reduce queueing on southbound Duluth Avenue and identify any significant reductions in delay for the intersection. Equal Opportunity Employer wsbeng corn K:\02865-0101Admin\Docs\Tragic operations memo 2015.09.11.doca Page 2 • Option A: o Alter the north approach to include separate left-and right-turn lanes, 150' of left- turn storage capacity was used. Option A can be viewed in Figure 2 in Appendix A.Approximate construction cost-$90,000 • Option B: o Alter the north approach to include separate left- and right-turn lanes, 150' of left- turn storage capacity was used. Southbound right-turning vehicles are given a free right with a yield to westbound through traffic. Option B can be viewed in Figure 3 in Appendix A. Approximate construction cost-$97,000 • Option C: o The intersection is realigned so the north and west legs become a continuous through movement and the east leg intersects them at a T as a stop controlled approach. Option C can be viewed in Figure 4 in Appendix A.Approximate construction cost-$118,000 • Option D: o Stop control is removed from Duluth Avenue and added to the east and west legs of Village Lake Drive, no geometric changes. Option D can be viewed in Figure 5 in Appendix A. Approximate construction cost-$1,750 • Option E: o Stop controls are added to Village Lake Drive making the intersection an all-way stop. Option E can be viewed in Figure 6 in Appendix A.Approximate construction cost-$2,500 The proposed improvements shown in Figures 2-6 were not taken into account during operation TRAFFIC OPERATIONS ANALYSIS Intersection operations are evaluated in terms of average seconds of delay per vehicle for the intersection, as well as average seconds of delay for each approach and turning movement. The average number of seconds of delay is broken into six ranges assigned letter grades A through F defining levels of service (LOS)as shown in Figure 7 in Appendix A. The ranges for unsignalized intersections are narrower than the ranges for signalized intersections. This is because many factors including the intangible factors of driver discomfort and frustration are considered. A one-minute delay at a red light is perceived as being more tolerable than one minute waiting for a gap in traffic at a stop sign, especially when there are vehicles queued behind. It is generally recognized that LOS D is the lowest acceptable LOS for urban intersections. Intersection capacity is also defined in terms of queue lengths of stopped vehicles. A 100-foot queue is approximately equal to four cars. Synchro/ SimTraffic software was used to simulate existing and future traffic operations at the intersection of Duluth Avenue and Village Lake Drive. Synchro is a macroscopic software application used for optimizing traffic signal timing and performing capacity analysis of roadway networks consisting of stop,yield, and signalized traffic control conditions. The underlying equations are based on Highway Capacity Manual procedures. SimTraffic is a microscopic software application that performs simulation and animation of vehicular traffic based on Synchro inputs. SimTraffic follows individual cars and uses a wide variety of variables (including some random variables)to simulate real-world driver behavior. K:\02865-010\Admin\Docs\Traffic operations memo 2015 09 I1.doox Page 3 Existing Traffic Counts Based on Mn/DOT 2014 draft annual average daily traffic (AADT)volumes,the existing daily traffic in vehicles per day(vpd)on the legs of Duluth Avenue and Village Lake Drive intersection is as follows: • Duluth Avenue north leg=3,750 vpd • Village Lake Drive west leg=4,450 vpd • Village Lake Drive east leg=4,450 vpd WSB collected 6 hours of turning movement count data at the intersection of Duluth Avenue and Village Lake Drive on July 29th,2015 during the hours 6:00 AM—9:00 AM and 3:00 PM—6:00 PM. Peak hours were determined by evaluating highest vehicle volumes at this intersection combined with volumes from the adjacent intersection at TH 13 and Duluth Avenue. Those counts were collected for the same 6 hours on October 22,2014 for a study conducted less than a year ago. Existing peak hour turning movement volumes are shown in Figure 8 in Appendix A. The intersection of TH 13 and Duluth Avenue was included to more accurately model traffic operations in the study area. MnDOT provided signal timing that was used for existing and future operations at the TH 13 and Duluth Avenue intersection with a cycle length of 160 seconds. Traffic Forecasts Based on a previous traffic study completed by Westwood in January 2015 for the Holiday Stationstore on Duluth Avenue south of TH 13, a 0.5%annual growth rate was applied to traffic volumes on Duluth Avenue and Village Lake Drive since they are collector roadways in a fully developed area. A 20 year growth factor of 1.9(annual growth rate of 3.2%)was applied to traffic volumes on TH 13 per the MnDOT State Aid website for Scott County'. Forecasted volumes for 2035 are shown in Figure 9 in Appendix A. Traffic Modeling and Operations Traffic operations at the intersection of Duluth Avenue and Village Lake Drive were simulated using PM peak hour traffic volumes. Signal timing for the adjacent TH 13 and Duluth Avenue intersection was obtained from MnDOT and used for 2015 and 2035 models. AM peak hour volumes were simulated in early stages of analysis but PM peak hour volumes trended as the worst case scenario for delays and queue lengths. Existing and future PM peak hour traffic volumes were modeled for the existing geometry and each of the five alternative options. Although the proposed geometric changes on Duluth Avenue will significantly improve the safety and operations on this segment of roadway and at the intersection of TH 13, it will have a limited effect on the amount of left turning vehicles at Village Lake Drive. This volume was assumed to be very low in terms of the number of vehicles turning in the peak hour and would be insignificant in terms of vehicle delay due to the reserve capacity of the intersection. The proposed improvements for the intersection of TH 13 and Duluth Avenue shown in Figures 2-6 in Appendix A were not included in the models to effectively use the provided signal timing from MnDOT. Detailed modeling results for the existing geometry and each alternative option are provided in Appendix B. ' http://www.dot.state.mn.us/stateaid/csah/TrafficFactors2O11.pdf K:02865O1OWdmin'Docs\Traf c opera ions memo 2015.09.1I.docx Page 4 Results show that the intersection of Duluth Avenue and Village Lake Drive experienced LOS A for the Existing Condition and all five alternative options for both 2015 and forecasted 2035 volumes. The existing geometry modeling results show the longest maximum queue lengths for the southbound approach reaching 188 feet in 2015 and 156 feet in 2035. Reduced maximum queues in 2035 are the result of random vehicle arrivals generated in the SimTraffic model,the average queue length did increase from 75 feet to 82 feet. Results for Option A show that maximum queue lengths for the southbound approach were reduced from 188 to 97 feet in 2015 and from 156 to 98 feet in 2035, differences of 91 feet and 58 feet respectively when compared with results for existing geometries and traffic controls. The cost of this option is relatively low compared to other alternatives and it does not introduce new safety concerns. Option A should be considered. When compared with Option A, operational delays for Option B were effectively the same as and maximum queues were not significantly reduced for the southbound approach. Option B is not recommended due to increased cost and reduced safety compared to Option A. The right- turn movement from Duluth Avenue is on a gentle radius encouraging vehicles to take the turn at increased speeds. It is also at close proximity to the hardware store entrance on Village Lake Drive,making rear end collisions more likely as vehicles slowing to turn into the entrance. For Option C,realigning the intersection makes it the most costly of all five alternatives. Since operations do not improve significantly beyond the other alternatives,the cost to benefit ratio is too high. Option C is not recommended. Option D reduces southbound queues significantly. The cost associated with Option D is the lowest of all five alternatives since there are no changes in roadway geometrics. The east and west legs do experience longer queues than the existing condition,but there is more storage space available on Village Lake Drive and existing turn lanes to help maintain mobility. The trouble with this solution is the violation of driver expectations when approaching a T- intersection. Drivers forced to stop on Village Lake Drive might expect southbound vehicles on Duluth Avenue to stop at the intersection as well,which could cause an unsafe condition when they release from stop into oncoming traffic. Likewise,vehicles on Duluth Avenue might come to a stop at the intersection when they see queues of vehicles on the east and west legs of Village Lake Drive causing confusion,unanticipated delays, and an increased potential for rear end collisions. Option D is not recommended but may still be considered as a cost effective option. Results for Option E show that maximum queue lengths for the southbound approach were reduced from 188 to 150 feet in 2015 and from 156 to 142 feet in 2035, differences of 38 feet and 14 feet respectively when compared with results for existing geometries and traffic controls. Although the cost of this option is relatively low compared to other alternatives,the improvements in queue lengths are insignificant and introduce minor delays and frustration for drivers on Village Lake Road. Option E is not recommended. K^02865-010 Admm\Does\Traffic operations memo 2015 09.II doex Page 5 Conclusion Option A is recommended at this time and should operate acceptably when considering the expected long term needs. Separate turn lanes should be constructed for the southbound left-and right-turning movements to alleviate queues caused by vehicle platoons from the TH 13 and Duluth Signal. Although this segment of Duluth is seeing queueing that can back up near the intersection of TH 13,these vehicle will continue to clear very quickly and therefore the average vehicle delay is minimal. The cost of maintenance will be similar to the existing condition,the added storage capacity will reduce the queueing by half on the north leg of the intersection, and it does not introduce any additional safety concerns.

History The City uses the Capital Improvement Program to schedule projects. In this case the Duluth Avenue Intersection has been identified for several years and is shown in 2015-2019 Capital Improvement Program. MNDOT has also been planning for the signal replacement at Highway 13 and Duluth Avenue for several years. Duluth Avenue approaches to the signal could be better configured to improve operation of the signal. This project would reconstruct portions of Duluth Avenue to better align with the signal system. Dedicated lane configurations (raised medians) could be adjusted for better signal efficiency. Access points on Duluth are in close proximity to the intersection and are affecting operations. On September 8, 2014, the City of Prior Lake approved a professional services contract with WSB & Associates for the Duluth Avenue Intersection Project. A portion of the work includes the preparation of a feasibility report. At the January 26, 2015 City Council meeting, the City Council approved concept 2 for construction with no median north of TH 13. At the February 9th, City Council work session, the City discussed the financing of all City projects for construction in 2015. The costs associated with these projects have an impact on the tax levy. Considering the high costs the City Council directed staff to review the possibility of reducing the scope of the Duluth Avenue project and the impacts of a scope reduction. Phone 952.447.9800/Fax 952.447.4245/www.cityofpriorlake.com Current Circumstances One option to reduce the scope of the Duluth Avenue Intersection project would be to only install the signal system and not complete the street modifications to Duluth Avenue. However, the new signal pole and signal head locations do not line up with the existing traffic lane configurations on Duluth Avenue if the new signal was constructed for the future roadway condition. The poles on TH 13 would be fine however their placement for the future intersection improvements would be pushed further away from the intersection making it very tough to accommodate pedestrian access. MnDOT would require sidewalk and additional pedestrian push buttons that would have to be removed in the future and MnDOT most likely will not approve of the temporary condition. Other impacts to this alternative include the following: Interim Cost Reduction — The costs associated with this option would reduce the overall costs by $708,120 and the overall Tax Levy by approximately $615,000 depending on how much of the project is still eligible for State Aid. Future Costs—A portion of the signal system would require modification. This modification would account for $180,000 in additional costs in the future. Traffic Impacts — Because the Duluth Avenue travel lanes would not be modified, flashing yellow left turn arrows would only be placed on TH 13 in the interim. Therefore Duluth Avenue would not substantially change from its current operation. The feasibility report discusses that the Duluth Avenue and TH 13 intersection will continue to degrade because of the geometric issue and by 2019 the level of service will not be acceptable. Presumably, the City would want to address the level of service issue by that time. For the above reasons, the staff does not recommend reduction of project scope. Instead we believe that the project timing should be shifted. The funding provided for the signal by MNDOT is for fiscal year 2016 which begins in July of 2015. The City has been discussing the construction in the summer of 2016 since it matches with the MNDOT funding. Delaying the full project until the spring of 2016 still meets MNDOT fiscal year 2016 timeframe. The project must be bid prior to June 30, 2016. Conclusion Considering the MNDOT funding cycle and the future impacts of not constructing this project by 2019, City Staff recommend delaying the full project for spring 2016 letting and construction. ISSUES: Holiday Gas Stations has expressed concerns with the median extension across their northern access off Duluth Avenue. They have requested the opportunity for additional input. The delay in this project should provide 2 additional time for the staff to work with Holiday, Lund's, Wells Fargo and others who may want to have additional input. City Staff has asked MNDOT to comment on the adjustment of the TH 13 access to Village Lake Mall. MNDOT has not yet provided commentary on that access modification. To provide for alignment of the travel lanes at the intersection, the current layout provides for a median on the northern leg of Duluth Avenue, however this median does not restrict access to Anna Trail. FINANCIAL The preliminary cost estimate for the full project is provided below: IMPACT: CONCEPT 2 Constr``ct o '*� 987 .50 Project $197,550 Support Costs Total { ul85,301,f;.
