extend pavement life. This prevents stormwater runoff from infiltrating through the pavement and into the underlying subgrade. As stormwater runoff enters pavement through cracks it can wash finer aggregate particles to the bottom of the aggregate base creating voids over time. Then as water accumulates in the underlying subgrade, frost heaving can occur during cold-weather months, further damaging the pavement. •Fogsealing/ Sealcoating - Protects and preserves pavement by sealing the surface to protect it from the negative effects of the sun(oxidizes the pavement), stormwater runoff(strips oil from the pavement),and petroleum products deposited on the pavement, all of which cause the pavement to become brittle and crack over time. • Overlays - Strengthens the pavement section by restoring a portion of the structural integrity of the pavement,while also helping to prevent moisture intrusion. •Reconstructions -Restores trails to a new condition. Staff proposes to construct ADA compliant pedestrian curb ramps to existing trail segments during maintenance operations at such time as the abutting trail segment receives an overlay or is reconstructed, or when the street the trail connects to receives an overlay or is reconstructed. Estimated Costs— Estimated costs will be dependent on numerous factors as discussed herein. After staff receives direction from the Public Works Committee tonight, estimated costs will be discussed with the Committee at the time the draft Trail Maintenance Policy is presented. Financing Options— Financing options for funding trail maintenance operations include annual budgeting through the general levy, purchasing General Obligation (GO)bonds on a project by project basis, or applying Park and Trail funds as applicable. Public -private partnerships (PPPs)are another option that might be applicable in limited instances. Each option has benefits and limitations which will be discussed in more detail when the draft Trail Maintenance Policy is presented to the Committee for review. Timeframe: Approximately 25 minutes for presentation and discussion.Approximately 20 minutes, including presentation. Observations/Alternatives: Staff requests Committee direction/feedback on any of the proposed policy framework discussed herein. Based on the feedback received tonight, staff will prepare a draft Trail Maintenance Policy for future consideration by the Public Works Committee. Funding Source: Proposed funding sources will be identified within the draft policy. Staff requests input on this item from the Committee. Recommendation: Staff recommends that the Public Works Committee provide as much direction to staff as possible to allow staff to develop a draft Policy that best reflects the desires of the Committee which will aid in future reviews. Action: Committee input is requested on all aspects of staffs proposed framework as discussed within this report. Attachments No file(s)attached. �� Form Review
