  15. Permeable Pavement Concerns • Spills and cleanup requirements • Verticle grades and sags • Surface Life • Low risk areas • Multiuse paths • Parking lots for new cars • Guardrail flares ?

  16. Water Quality Feature Considerations • Location-accessibility to maintain • ODOT has a prioritized list for these features based on life cycle costs • Try to minimize propriety parts needed • Maintenance Costs • Disposal of materials from clean outs • Frequency of clean outs • Replacment Parts • Equipment required to clean out • Must have a maintenance and operations plan

  17. Impact Attenuators • Low Maintenance Group now on the Qualified Products List • Issues • Numerous different replacement parts may be needed if lots of variety on the system • Time and Costs to repair • Safety of the crew and the public • Traffic delays resulting in more emissions
