Comments:
D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project.*
Design of the outfalls were made to avoid all wetland and stream features.
Vegetation cleared in the buffer zone will be re -planted with grass to provide access
to the outfall during the length of the project.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
The limit of disturbance (LOD) was designed to be only as wide as necessary to
give machinery access for construction and limit the need of clearing vegetation in
the buffer zone.
2. Buffer Mitigation
2a. The table below identifies the square footage of impact to each zone of the riparian buffer and the required mitigation.
