Frontenac Corridor Road Needs Study - 2013 D.M. Wills Project Number 13-4449 D.M. Wills Associates Limited PARTNERS IN ENGINEERING Peterborough North Bay January 2014 Executive Summary As a result of Ministry of Transportation highways downloads, the Townships of North, Central, and South Frontenac and Frontenac Islands assumed their respective geographic portions of former Highways 506, 509, 38, 95 and 96. These highways, connected together provide for a complete corridor through the County of Frontenac and across Wolfe Island, coined the “Frontenac Corridor”. While providing a County/Regional transportation function, these roads remain the responsibility of each of the local Townships. The Townships of North, Central, and South Frontenac and Frontenac Islands recognize the regional function of this road corridor as a commuter, commercial and recreational link across the Townships. In such, they also recognize the benefit in managing the corridor collaboratively to ensure the application of consistent road standards and treatments throughout and to ensure the overall health of the entire road corridor. To this end the Townships have agreed to partner in the management and funding of the “Frontenac Corridor”. In particular, the Townships have lobbied to see the Frontenac Corridor considered as a separate entity by higher levels of government in consideration for future funding opportunities. The Townships intend to be proactive in their response to potential future funding opportunities with respect to roads and in particular the Frontenac Corridor. An assessment of the road network and a related asset management/financial plan for road maintenance and improvement is necessary to support future funding requests. The collective Townships of Frontenac Islands, South Frontenac, Central Frontenac and North Frontenac jointly retained the services of D.M. Wills Associates (Wills) to undertake a review of the Frontenac Corridor and develop a road maintenance/improvement plan. Data collected as a result of the field review was used to develop a prioritized listing of the road network needs, the results of which are documented in this report. The Frontenac Corridor (the Corridor) spans a total of approximately 185 km primarily within a rural setting. The road network includes surfaces of both low class bituminous (LCB)( surface treatment) and high class bituminous (HCB) or hot mix paved (asphalt). The Corridor has approximately 111 km of surface treated road (low class bituminous (LCB)), and 74 km of asphalt paved road (HCB). An overall corridor adequacy has been calculated based on a number of road characteristics including: Capacity Structural Adequacy Geometrics Drainage Surface Condition Maintenance Demand Shoulder and Road Widths i The overall corridor adequacy for the 2013 Road Needs Study is 42%. However, all of the roads identified as deficient are such due to inadequate surface type based on current traffic volumes; their overall structural adequacy and surface condition generally being good. Stated another way, the corridor is fully adequate except for a number of road sections which are considered to have a less than desirable road surface type given the traffic loading. The adjusted adequacy rating, excluding surface type deficient roads, is 100% Capital Improvements Prioritization and recommendations for planned capital improvements have been developed based on condition rating and traffic demands on each road. Those roads identified as having a “NOW”, “1-5” and “6-10” year capital reconstruction requirement (with the exception of drainage improvements) have been included in the capital plan. Road segments noted as a now need strictly due to surface type have been excluded from the plan as it is felt most appropriate to replace and upgrade the road surface only after the full service life of the existing pavement is realized. Upgrading of the road surface is recommended with the next reconstruction cycle. The total length of approximately 32 km of road was identified for capital reconstruction works in the Now, 1-5, and 6-10 year periods i.e. over the next 10 years. The estimated cost of the capital works is approximately $ 6.0 M. Resurfacing Based on the noted typical degradation rates for surface treatment and hot mix, a resurfacing program/budget is recommended as follows: Surface Treated Roads: 111 km of surface treated roads (LCB) Degradation rate 0.625/year (rating drops from “10” to “5” over a 8 year period) Annual Resurfacing 14 km/year Annual Budget $308,000 (14 km/yr. x $22,000/km ST1) Hot Mix (Paved) Roads: 74 km of paved roads (Asphalt) Degradation rate 0.25/year (rating drops from “10” to “5” over a 20 year period) Annual Resurfacing 4 km /year Annual Budget $ 1,144,000 (4 km/yr. x $143,000/ln RMP1 x 2 lanes) ii The total resurfacing program, (hot mix and surface treatment) is estimated at $1,452,000 per year, or approximately $7.26 M over the next 5 years. The relative allocation of resurfacing costs between individual Townships will varying depending on the location of the priority road sections. Preventative Maintenance It is recommended that regular maintenance in the form of roadside ditch cleanout and clearing be undertaken in order to extend the useful service life of the existing roads. Additionally, preventative maintenance in the form of crack sealing is recommended, as detailed in the recommended work plan. iii iv Table of Contents 1.0 Purpose, Background and Study Method ...................................... 1 1.1 Purpose ............................................................................................................................ 1 1.2 Background .................................................................................................................... 1 1.3 Study Objectives ............................................................................................................ 2 1.4 Study Methodology ....................................................................................................... 2 2.0 The Road System .............................................................................. 4 2.1 Existing Infrastructure ..................................................................................................... 4 2.2 Traffic Data ..................................................................................................................... 7 3.0 State of Infrastructure ....................................................................... 7 3.1 General Information ...................................................................................................... 7 3.2 Critical Deficiencies ....................................................................................................... 7 3.3 Priority Ratings of Roads ................................................................................................ 8 3.4 Road Needs Study Summary Table ............................................................................. 9 3.5 Types of Improvements ................................................................................................. 9 3.6 Benchmark Construction Costs.................................................................................. 10 3.7 Preliminary Recommendations .................................................................................. 10 4.0 Level of Service .............................................................................. 12 5.0 Best Management Practices ......................................................... 13 5.1 Preservation Management Approach ..................................................................... 18 6.0 Improvement Plan .......................................................................... 20 6.1 Capital Improvements ................................................................................................ 20 6.2 Resurfacing ................................................................................................................... 22 6.3 Road Maintenance ..................................................................................................... 26 6.4 Guide Rail ...................................................................................................................... 26 7.0 Discussion ....................................................................................... 26 7.1 Structures ....................................................................................................................... 26 7.2 Replacement Cost ...................................................................................................... 28 7.3 Prioritization of Projects................................................................................................ 28 7.4 Integrated Capital Planning ...................................................................................... 28 v List of Appendices Appendix A – Road Needs Summary Spreadsheet Appendix B – Road Improvement Costs Appendix C – Level of Service vi Frontenac Corridor Study 2013 Townships of Frontenac Islands, South, Central and North Frontenac 1.0 Purpose, Background and Study Method 1.1 Purpose The collective Townships of Frontenac Islands, South Frontenac, Central Frontenac and North Frontenac jointly retained the services of D.M.
