EW-6: Habitat Restoration

2 points

Goal

Maintain or improve biological integrity of receiving watersheds or improve an offsite habitat area.

Requirements

  1. Complete a biological assessment that determines the current Index of Biological Integrity (IBI) score based on the lowest practical taxonomic level for local bioindicator species for a watershed receiving stormwater runoff from the roadway right-of-way or at an offsite location (e.g. a wetland bank).
  2. Determine the applicable regional or site-specific reference stream condition level for IBI as shown in Table EW-6.1.
  3. Implement a restoration plan that:
    1. Restores an area equal to the total disturbed surface area of the project.
    2. States the watershed’s current IBI and the restoration goal IBI.
    3. Describes ecological design or engineering elements that are expected, with reasonable professional certainty, to raise the overall IBI score by one stream condition level as shown in Table EW-6.1. Include a description of data collection activities, existing watershed data and data quality.
    4. Lists responsible parties for restoration activities.
    5. Lists sources of funding for restoration activities.
    6. Completes restoration activities by the time the roadway facility opens to traffic. Include a schedule of restoration activities.
    7. Is signed and approved by the responsible parties or the project ecologist.
