This plan addresses the lifecycle maintenance and rehabilitation of the City street system. The purpose of this plan is to provide the City with a tool to assist in planning roadway improvements by properly matching the maintenance and rehabilitation method with the pavement condition. The Plan goal is to extend the life of the City streets and reduce lifecycle costs. The Pavement Management Plan identifies proposed street maintenance and rehabilitation options, estimated costs in year 2008 construction data, and recommended improvements program. We would be pleased to meet with the City Council and Staff to discuss the process identified in this Plan at any mutually convenient time. Sincerely, BONESTROO Paul T. Hornby, P.E. I hereby certify that this plan, specification, or report was prepared by me or under my direct supervision and that I am a duly Licensed Professional Engineer under the laws of the State of Minnesota.

The purpose of this report is to provide information to guide decision making for street maintenance and rehabilitation including: 1. Developing a pavement management plan that will preserve and/or improve the quality of the City's streets in a fiscally responsible manner. 2. Developing and implementing a plan that considers immediate and long term needs. 3. Preparing a systematic plan and a workable method of financing. 4. Providing information for the public to be better informed and involved in decision making. Summary of Findings The study identifies the pavement condition for each City street and the most cost effective method of maintenance for different points in the street's life cycle. Table la provides the estimated cost per lineal foot for five different pavement rehabilitation options for the City's 70+ miles of streets. These cost estimates include 15% for contingencies and other costs associated with the improvement projects. The reconstruction of streets would involve analysis of each individual street to determine whether to widen the street to City standards or reconstruct it to its existing width in order to maintain the character of the area. Detailed cost estimates for each of the five options can be found in Appendix B of this report. Table 1 b provides a summary of mileage and condition rating for the City.

Although it is recommended that some streets be fully reconstructed, the lifecycle of many existing streets can be extended using less expensive rehabilitation options. Some of the streets included in this report are proposed to undergo mill and overlay rehabilitation. The City could choose to allow these streets to deteriorate further until complete reconstruction is required, or pursue the mill and overlay option. We suggest this as an option to perform critical maintenance on streets with higher condition ratings in an effort to extend the pavement lifecycle, while postponing more costly maintenance on streets with lower condition ratings. We recommend that the City continue an ongoing crack fill and seal coat program to extend the life of the streets with condition rating of 7 and higher. Analysis Methodology Basic source data was collected to develop the information and recommendations presented in this report. The data collected consists of the following: 1. A pavement condition evaluation of all City streets to produce a numerical pavement condition index using the Pavement Surface Evaluation and Rating (PASER) system, which rates the existing condition of the pavement based on visual surface observation. 2. An inventory of the characteristics and past maintenance on each street. 3. Input from the City Staff on existing street conditions. This data was studied and professional judgment from both an engineering perspective and rehabilitation perspective was applied to develop the opinions and recommendations presented in this report. City of Scandia Project No.568-08137-0 Pavement Management Plan #Bonestroo Page 5 CITY OF SCANDIA - PAVEMENT MANAGEMENT PLAN Introduction Street Lifecycle The City of Scandia should consider various programs to maintain its streets including routine seal coats. The following figures identify the life cycle of a typical street and the required maintenance based on condition. Asphalt pavements perform well, deteriorating slowly during the first ten years of the street lifecycle, and then tend to deteriorate more rapidly. Proactive maintenance in the early years of a street lifecycle such as, repairing cracks and seal coating is recommended as a cost effective maintenance practice. As the pavement condition deteriorates and surface observations indicate a significant level of stress due to traffic loading, seal coat applications are no longer recommended as the most cost effective maintenance. This condition is illustrated in Figure 1, when pavement condition ratings fall below condition rating of 6. Figure 1 generally illustrates that street's condition will deteriorate 40% during the first 75% of its life, and another 40% during the next 12% of its life. A streets condition will deteriorate quickly beyond 75% of its life, which typically occurs 15 to 20 years after a street is constructed. Preventative maintenance during the early stages of a pavements lifecycle can be the most cost effective method for extending the life of a pavement, as shown in Figure 2. By protecting the road subgrade from the negative affects of water intrusion with crack sealing or pavement replacement, additional cost savings can be realized in future lower cost reconstruction methods. The five maintenance and rehabilitation options listed in Table 1 can be considered for maintaining public streets.

Time/Traffic City of Scandia Project No.568-08137-0 Pavement Management Plan #Bonestroo Page 7 CITY OF SCANDIA - PAVEMENT MANAGEMENT PLAN Existing Conditions Street Condition The condition of a street is affected by a number of factors, including: • Surface condition (roughness, cracking) • Drainage (street profile, cross section, storm sewer) • Street section (bituminous and gravel base thickness) • Subgrade soil (sand, clay, silt) • Traffic characteristics and loading • Age • Maintenance program (crack filling, seal coating, patching) Each of the above listed items contribute to the overall condition and lifecycle of a public street. It is not uncommon for streets in the same area, constructed at the same time, to vary in condition. This makes it difficult to develop an efficient street rehabilitation program that can be applied uniformly to adjacent areas. The majority of the streets in the City follow a general condition rating curve. Street Surface Evaluation The streets in Scandia were evaluated using a visual survey that observed the condition of the pavement surface. The pavement was rated using the PASER (Pavement Surface Evaluation and Rating) System. The methodology is based on a consistent numeric rating scale ranging from 10 for a newly surfaced street to 0 for a failed surface. The results of the pavement condition survey are shown with the Street Inventory in Appendix A, Figure F002. Table 2 shows a general summary of recommended maintenance and rehabilitation options based on the current pavement condition rating.

Figure 3 below illustrates the lifecycle data of City streets over time by plotting the PASER pavement rating versus age.

Depending on the goals and budget for the City, various approaches can be taken with the information compiled. If the City's main goal is to focus on maintaining existing streets, more emphasis should be put on the crack filling/seal coating, bituminous patching, and mill and overlay options. The following is a description of each proposed maintenance method and the potential benefits of each. Sea/Coat—provides for the installation of a thin surface coating, typically an oil emulsion and trap rock to reseal the pavement surface. This provides for an extension of the pavement surface life by minimizing the effects of the sun and weather on the existing bituminous material and reestablishing a wearing surface with a higher level of friction than the existing pavement. This cannot prevent ultimate pavement failure due to age or poor sub-grade conditions. Crack Fang— provides for the sealing of cracks in the existing pavement through a route and seal, where the existing cracks are ground out to a consistent width and filled with a sealant. This procedure reduces the amount of moisture and debris entering the pavement sub-grade through surface cracks. This protection provides for a more stable roadway base and can reduce pavement breakup and potholing due to the effects of freeze/thaw cycles. Patching— provides for the correction of localized pavement deterioration typically known as pothole filling. This process can include the replacement of small areas that have experienced pavement failure due to a soft base material or other contributing conditions. Patching also provides for a smooth driving surface and extends the life of the pavement. Mill and Overlay or Overlay—provides for the addition of another layer of bituminous pavement on the existing roadway. This can be performed either through the removal by milling of a thin layer to maintain the current surface elevations and then placing the overlay pavement, or by placing an • additional layer of pavement on top of the existing surface. This extends the life of the roadway by adding additional material to the surface, = ! __ reestablishing the cross slope of the road to promote drainage and creating a smooth driving surface. This method typically results in reflection of existing cracks in the roadway appearing in the new surface within 1 to 2 years. City of Scandia Project No.568-08137-0 Pavement Management Plan 4 Bonestroo Page 10 f t /....\ /......\ ,...'.. Pavement Reclamation— provides for the full depth grinding of the existing pavement in place. it! y This process blends the existing pavement into a the aggregate base, grades the blended surface to restore cross slope, provides a new bituminous surface, and typically provides for a stronger Yp Y roadway section. This method can be a cost effective means to replace the pavement and strengthen the road by reusing the existing pavement instead of removing the pavement and hauling it away. This process provides for an entirely new roadway surface with a stronger base and is typically cheaper than full-depth reconstruction. Full Reconstruction— provides for the removal of the existing roadway and the rebuilding of the road from the sub-grade through bituminous surface. Sub-grade correction consists of the removal of unsuitable materials, backfill with granular materials and draintile at low points, aggregate base and bituminous pavement. This method is typically applied in areas where pavements are showing significant areas of major distress. Utilities Proposed utility improvements are not analyzed in this report. However, some quantities were added to the full depth reconstruction costs for replacement of storm drains and culverts. If full reconstruction of a street is considered, it will need to be reviewed further for necessary storm drain improvements or other potential utility improvements at that time. Other maintenance items that should be considered over time include the cleaning and/or regrading of ditches and culvert maintenance to provide storm capacity for roadway drainage. Proposed Lifecycle In analyzing the best alternative for the City of Scandia, a number of different methods and staging were reviewed. This analysis looks to find the most cost effective method for the City to use in preserving its pavement. Five options were analyzed to better understand the cost of long-term maintenance strategies on the City system as a whole. Appendix C outlines the costs of each option as well as the impact the dollars will have (e.g. what percentage of paved streets will the City be able to maintain with this budget?). Option 1 depicts the City's current maintenance budget of $250,000, which will maintain 24% of the total paved mileage over a 5-year period. In contrast, Option 2a maintains 58% of the City's paved mileage with an average annual budget of $370,000 over 5 years. A 48% increase in annual budgeting yields a 142% increase in maintained mileage. Option 2a is compared with an average annual budget, however, the recommended five year budget is actually front-loaded in the first three years with a proposed budget of $618,375, and the last two years funded in the amount of $64,950 for crack fill and seal coating. An additional $318,150 for mill City of Scandia Project No.568-08137-0 Pavement Management Plan ,#'Bonestroo Page 11 and overlay in the 4th year of Option 2a could be budgeted to provide maintenance for all of the streets with condition rating 7 and higher. It is recommended that the City employ a strategy in which it prioritizes maintenance activities for the streets which are currently in good condition. While it may be tempting to follow a "worst- first" plan, that strategy is typically the least cost-effective. Prioritizing and maintaining the City's best streets extends the lifecycle and reduces deterioration to a condition that requires much more costly rehabilitation. This helps ensure the system as a whole is in the best possible condition and the maintenance dollars are being maximized. Option 2a in Appendix C outlines this recommendation. As can be seen in the Table 4 below, increased maintenance dollars for crack fill and seal coating streets with condition rating of 7 and higher (Option2a) minimizes the amount of streets deteriorating to the point of needing costly reconstruction. Table 4—Option Cost Comparison Option 1 Option 2a Average Annual Maintenance Budget $250,000.00 $370,005.00 No. of Years 5 5 5 Year Maintenance Subtotal $1,250,000.00 $1,850,025.00 Feet of Street Needing Reconstruction 262,545 143,660 Cost ($/If) $140.00 $140.00 Reconstruction Cost Subtotal $36,756,252.27 $20,112,400.00 Total Cost $38,006,252.27 $21,962,425.00 The life cycle proposed below in Table 5 is recommended based on cost and impact to the entire system.

City of Scandia Project No.568-08137-0 Pavement Management Plan Bonestroo Page 11 CITY OF SCANDIA - PAVEMENT MANAGEMENT PLAN Cost Estimate The costs associated with street rehabilitation will vary, depending on the construction process required. The costs to remove and reconstruct the existing bituminous and gravel base surfaces will be much greater than milling, reclaiming, patching, and overlaying streets. In addition, streets with existing curb and gutter and/or storm sewer will include additional costs for improvement or replacement of these features. Detailed costs are included in the Appendices related to the methods discussed. In addition, the proposed cost of the different life cycle options analyzed is also included. The following table summarizes the lifecycle cost per foot of street for the proposed lifecycle identified in the previous section of this report. Table 6 - Lifecycle Cost Per Lineal Foot Maintenance Year Cost/LF Seal Coat & Crack Fill 6 $7.00 Seal Coat & Crack Fill/Patch 12 $11,00 Mill Overlay 16 $40,00 Seal Coat/Patch 21 $11.00 Seal Coat/Patch 26 $11.00 Reclaim/Reconstruct 31 $70,00 Cost over 31 year life $150.00 Cost per foot per year $4.84 City of Scandia Project No.568-08137-0 Pavement Management P/an 4 Bonestroo Page 13 CITY OF SCANDIA - PAVEMENT MANAGEMENT PLAN Financing The City currently has a Street Maintenance Fund that receives an allotment of approximately $250,000 per year. This fund has been used over the past to perform annual maintenance such as patching, crack filling, and seal coating. This funding amount was used as the basis for the proposed life cycles reviewed in this report. The current amount of funding will not be sufficient to maintain all of the streets in the City and is not enough to cover the costs of major maintenance or reconstruction methods. In order to fund an increased pavement management budget, additional sources of revenue may need to be reviewed including: 1. General Tax Levy 2. Special Assessments 3. Street Utility Fee (Currently not allowed by Statute) General Tax Levy Minnesota cities are required by law to hold a yearly public hearing to receive comments on the types of services proposed for the upcoming year, as well as the associated costs. These public hearings are referred to as Truth-in-Taxation hearings. The proposed budget and proposed property tax levy and their percentage increases from the current year levels are typically discussed at the hearing. The Pavement Management Program would therefore be addressed as part of the budget preparation process. The main advantage of using funds from the general fund is that justification of direct benefit of a particular project to a property is not required. A major disadvantage is that priorities can change rapidly and dedicated funding may prove difficult to rely on from year to year, or even be inadequate. Special Assessments Special assessments are an indirect form of taxation. They are a way for cities to charge certain properties for the cost of making a local improvement, or to collect certain charges that will benefit those properties. Minnesota Statute, Chapter 429, encompasses public improvements such as street improvement projects including grading, curb and gutter and surfacing, sidewalks, and street lighting. Cities may use special assessments to recover the cost of public improvements if the city has adopted an ordinance to provide for it. The amount that is charged to a particular property must be based upon the benefit that the property will receive from the improvement. Cities cannot charge an amount greater than the amount the benefit will increase the value of the property. There are many advantages to using special assessments as a funding source. They are a means of raising money outside the general city tax resources. Special assessment bonds do not count City of Scandia Project No.568-08137-0 Pavement Management Plan Bonestroo Page 14 towards statutory debt limitations. They provide a means of levying charges for public services against properties otherwise exempt from taxation. Perhaps the chief value of special assessments is that by charging the property owner for the benefit received, they prevent or minimize the possibility that a property owner will benefit from the improvement at the expense of the general taxpayer. Street Utility Fees Street Utility Fees are proposed from time to time through the legislative process, but have not been approved to date. Street Utility Fees provide a method for Cities to collect annual fees from land owners to supplement maintenance activities and reconstruction priorities. An example of the funding resource that could be generated through the use of a Street Utility Fee; 1,500 households contributing $120 per year (or $10 per month) would generate $180,000 towards the annual street budget. Budgetary Costs The costs presented in the Appendices for the various options can be used for budgetary purposes for setting an annual maintenance amount or determining other funding options that the City could draw upon. City of Scandia Project No.568-08137-0 Pavement Management Plan Bonestroo Page 15 CITY OF SCANDIA - PAVEMENT MANAGEMENT PLAN Conclusions and Recommendations This report provides information to be used in determining an annual maintenance budget for the City streets and can be used as a policy for the future maintenance of the City streets. The results of this plan provide for a summary of the potential costs and different life cycle options that can be used as a model for the City system. It is recommended that the City increase the maintenance budget in an effort to maintain streets with a condition rating of 7 or higher. As demonstrated in Appendix C, it is much more cost effective to maintain these streets with crack fill and seal coat programs than it is to let these deteriorate any further. Within this report, the recommendations are as follows: • Adopt this plan as a framework for future maintenance of City Streets • Order a feasibility report prior to any major maintenance projects such as reclamation or reconstruction to determine actual project costs and the potential revenue sources for specific projects. • Based on the options of this plan, review the annual maintenance budget and determine if adjustments are feasible for the City.
