Supporting Webinars for Conservation Districts

  • Stream Crossing Exemptions and Notifications: (112 MB) (~41 minutes) This webinar reviewed the notification and exemption process for stream crossings with some examples. (1/2023)
  • Stream Crossing Replacement Site Prioritization: (94 MB) (~1 hour) This webinar will focus on site characteristics and various metrics that can be utilized to identify high priority stream crossing replacement sites. Districts can use this to steer municipalities into applying for these sites and consider incorporating these metrics into the local ranking criteria. Will include discussion of various existing tools that can be used to identify high priority sites as well as leveraging other funding sources. (2/2025)
  • Stream Crossings – Status Update and Emerging Issues: (133 MB) (~1 hour, 19 minutes) Status update on the implementation of the new stream crossing standard. Included a review of some recent issues encountered on projects and conservation district responsibilities. (2/2024)
  • Online Longitudinal Profile Tool: (133 MB) (~1 hour, 1 minute) The Center has been working with developers at Penn State to turn the excel-based “Long-Pro Tool” into an online program. This tool can be used by CDs and others to input longitudinal profiles surveys for potential stream crossings to generate potential recommendations. The new online “Long Pro Tool” is more user friendly than the excel version, and provides an online repository for this data. The tool is located in the Stream crossings general resources webpage.

  • Stream Crossing Replacement Monitoring: (84.6 MB) (~ 33 minutes)This session included a recap of a multi-year study on Hammond Run (large squash pipe replaced on Shaver’s Creek Road in Huntingdon and shown at workshops). It also included some ideas and discussions for CDs who might be interested in implementing some monitoring of their own for stream crossing replacement projects. (2/2023)
