for asphalt is $24,000 and noted that the material alone for the one job was $2,000. He stated that there are many areas in the city in similar condition that cannot be fixed by shoveling material out of a truck. Chairperson Riley commented that this does seem very inefficient and asked what else could have been done. Public Works Superintendent Riemer replied that this work should have been done 20 years ago. He stated that those roads are all due for reconstruction. He commented that the workload and number of continued calls from residents is overwhelming. Chairperson Riley commented that more recently they have switched to reconstruction of roads in poor condition rather than overlay. He asked staff to provide more information on mill and overlay. City Engineer Westby reviewed the general costs for mill and overlay projects versus reconstructions. He reviewed the criteria used to determine when an overlay would work or whether reconstruction is needed. He stated that if you mill and overlay a road in too poor of a condition, the cracks would just come back through and the life of that improvement would not be realized. He stated that he would never recommend a mill and overlay for streets needing reconstruction. He noted that they are attempting to do more mill and overlay projects on the roads that would benefit in order to fulfill the full life of those roads, and the roads needing reconstruction are simply waiting for their time. He noted another option may be to add a light reconstruction option to reduce project costs while achieving a twenty to forty -year design life, allowing more streets to be reconstructed each year to reduce annual maintenance needs. Councilmember Woestehoff recognized that about $20,000,000 is needed in the next five to ten years to fund these needed reconstruction improvements. He stated that he would prefer to stick with the reconstruct and overlay options and not gamble on the light reconstruction option. Chairperson Riley asked what has changed from six years ago when the original estimate and plan was developed. Councilmember Musgrove asked for, and obtained, clarification on roads included on the list that she believed did not need reconstruction. Staff confirmed that all those roads are accurate. Chairperson Riley commented on the potential to borrow against MSA funds but recognized that would impact the availability of funds in the future as well. Councilmember Woestehoff asked that a map be provided showing both the reconstructs and overlays. Chairperson Riley noted that it was mentioned that some of the further out roads on the plan could be overlayed earlier to extend the lifespan and asked if that would help.
