The success of this Master Plan will be in its implementation. This Chapter provides a summary of conclusions of the Master Plan and a prioritized list of actions to be followed in order to implement the recommended plan components identified in Chapter 5. To facilitate implementation, the plan components have been organized by priority for implementation (high, medium, low, and other). Within each priority, the components are organized according to whether they are a policy and programmatic related or a project related recommendation. Each recommendation is referenced back to the Issue ID identified in Chapter 5 and summarized in Table 5-2. For the high priority recommendations for improvement, steps for implementation have been identified. A check box has been provided in front of each step and can be used to check off the steps completed as the implementation progresses.  Exhibit 6 shows the location of the different priority projects.
