Conclusion-Early identification of potential opposition :
• Regulatory agencies• Neighboring community• Political• City plans and projects
-Developing engagement strategies• Participation in the design phase• Site visits at different stages of the project• Board member constituencies
-Engineering and Construction Team Understanding of Environmental Challenges-Developing documents with emphasis on the benefits of the project (i.e., environmental, infrastructure safety and reliability, property value)
