PAVEMENT MANAGEMENT POLICYj Oty of Otsego Draft: February 11, 2014 Adopted: Index Pavement Management Policy 11 Pa g e The Pavement Management Policy (Policy) isa plan for street maintenance. The City will maintain City streets in a manner that extends their useful life as long as possible before reconstruction by allocating financial resources for maintenance in atimely and effective manner. Proper monitoring that leads to maintenance techniques and strategies applied at the optimum time prolong pavement life thereby reducing costs for property owners. Objectives The objectives of the Policy are: 1. Extended Lifecycle of Streets- Without proper maintenance, pavement deteriorates at a high rate; with timely maintenance, the life of local roads can be extended as is shown below: S)urce: American Public Works Association 2. Create Efficiency -Through consistent evaluation and maintenance of streets, they will be maintained at the proper timeswith the correct technique creating efficiency of contracting, engineering, and staff allocation. 3. Financial Stability- The ability to schedule an effective street maintenance strategy will allow the City to forecast and prepare for future funding requirements. This lead time will allow the City to apply for grants and other funding sources. Pavement Management Policy 21 Pa g e The Citywill use the following criteria, methods, and systems when evaluating and maintaining City streets. Unique circumstances may require deviation from the policy upon approval of the City Council. Street Rating System The City will use the Pavement Condition Index (PCI) to rate the condition of all City streets. Streets will be evaluated every three years with one third being rated each year. The computerized database computes the rating based on a 0 to 100 weighted scale based on eleven rating factors. The PCI number will be used as a guideline for suggested maintenance. Streets that have a PG of between 60 and 70 will not benefit from ongoing maintenance techniques and will only receive patching also known as Preservation Maintenance. The City Engineer may use discretion in placing a street under Preservation Maintenance; the PG rating isthe main, but not the sole factor in determining the proper maintenance timing and technique. Collection of Maintenance Project Data All maintenance data such as date of maintenance and type along with project costs for each street section shall be maintained by the Public Works Department in an accessible electronic data base. Annually, a review of the costs of maintenance and scheduling of maintenance shall be conducted. Pavement Maintenance Techniques Various maintenance techniques are utilized to maintain streets. The techniques applied to astreet vary depending upon the age, condition, remaining useful life, and other factors. The proactive maintenance techniques include the following: • Crack filling— includes routing the cracks open (3/4") and placing a flexible bituminous material within the routed opening • Crack filling with Fog Seal - crackfillingfollowed byathin layer of bituminous material over the entire street to slow the loss of the fines, seal any minute cracks and provide a barrier to the sun's harmful rays • Crack filling with Chip Seal (Seal Coat) and Fog Seal - crack filling followed by a thicker layer of bituminous material over the entire street, then embedding a layer of small aggregate rock within the bituminous material then applying a fog seal to lock in the small aggregate rock. This increases the friction of the street for safer vehicular trafficwhile sealing the street preventing loss of aggregate, intrusion of water while providing a barrier against the sun's harmful rays. Pavement Management Policy 31 Pa g e When a street's PG falls to a level of between 70 to 60, it will move from proactive maintenance and begin the preventative maintenance period of the asphalts life cycle. • Preventative Maintenance (Patching) - includes o &in patching -for minor surface deficiencies up to 1" in depth o Full depth patching- for potholes and areas or severe cracking o Infrared patching- for repair near utility lids o Coldpatching-fortemporaryrepairsduringwinterseason Streetsthat have reached the end of their useful life and will no longer benefit from the above maintenance techniques because the cost exceedsthe return in extended life span will be considered in Preventative Maintenance and only patched until such time an improvement project iswarranted. Types of improvement projects are: • Overlay - a 11/2" thick layer of asphalt over the entire street to provide additional strength to the street - placed on streetswithout concrete curbing • Mill and Overlay — prior to the overlay the surface of the street is removed 1 %" down so the overlay matchesthe curb lip and utility lid elevations- performed on streetswith concrete curbing and municipal services • Micro surfacing — two thin layers of 3/8" thick slurry type asphalt that are self -leveling and provide some additional strength to the pavement surface while removing deficiencies such as rutting and spalIing. • Reclamation - full depth grinding of the existing pavement then re -compacting in place, sometimeswith the addition of bituminous for a recycled in place asphalt mat, then generally overlaid withl %" of new asphalt - prevents reflective cracking form occurring while providing a rejuvenated base with a new surface • Reconstruction - removal of all asphalt and curb, then adding to the base before new asphalt is applied in two layers generally 3 %" thick Pavement maintenance will be completed as listed below. The following maintenance schedule will be applied to all new pavements. Staff may recommend changesto the maintenance schedule to the city Council based on the condition of the street and related factors.

The street classification dictates the design standard. Major Collector - connect or terminate at other major collectors or at County Highways and are generally spaced Y2mile to 1 mile apart to create a grid system - primarily the City's designated Municipal State Aid street Minor Collector - connect major collectors more directly than local streets Local -provide localized access to homes and business Street Design,9tandards All new City streets are constructed to the City's requirements based on the street classification and type of street. All streets needing reconstruction will be reconstructed to the current City standards for that street's classification and type per the City's engineering design standards found in the Engineering Manual. Pavement Management Policy 51 Pa g e Average Daily Traffic (ADT) countswill determine the street classification and, thus, the design standards. Paved streetswith an ADTof lessthan 200 needing rehabilitation may be reverted to gravel. The City will make the determination based on ADT, city needs, and future development. Residents may petition to have the street repaved by waiving their rights to appeal an assessment and by agreeing to pay the full reconstruction cost including overhead. Asphalt curbed streetswill be reconstructed with surmountable curb. All street reconstruction will comply with current Americanswith Disabilities Act (ADA) standards. Street width will be asfollows: Existing Width Less than 28' 28' 33' or greater Reconstructed Width Infrastructure Paplacement and Installation per approved feasibility report 28' 33 unless commercial or industrial All infrastructure will be reviewed at the time of street reconstruction. Infrastructure includes: • Water • Waste Water • Storm Water • 9dewalksand Trails • Lighting • Culverts In areaswhere municipal services do not currently exist, the city will review the feasibility of extending municipal water and wastewater services, adding storm water management systems, and adding sidewalks or trails in accordance with the City's ordinance requirements. city will only provide a feasibility report if a majority of the residents inquire about the extension of services to their property. If private water and wastewater systems are failing and are considered a health or environmental hazard, municipal services will be extended unless doing so is not financially feasible as determined by the city. Pavement Management Policy 61 Pa g e Private Utilities in Rghtsof Way All private utility companies using a street right of way to serve the project area will be contacted to allow for private utility system improvements while the project area is under construction and accessible. Street Sims All street signage will be reviewed at the time of seal coating, fog coating, and overlay projects and replaced in accordance with the City's sign replacement policy. Rghts-af-Way Considerations • S)d Restoration - replaced with seed and mulch • Irrigation - at owner's expense • Fence or other in right-of-way- removed and not replace • Mailboxes- replaced with group mailboxes as per USPbstal requirements and included in assessment • Driveways and aprons- replace in kind in accordance with City ordinance and standards Financing To be completed.
