D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Due to the location of the existing easement and limitations as a result of tree conservation buffers on the site as
well, the sewer line was extended straight from the existing sewer line, through the existing easement, through
the 32' buffer to a proposed manhole 15' from the buffer. The line then immediately turns towards the south to
avoid any other impacts.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Construction will be limited to within the easements only. The grades will be returned to the existing conditions
after the line has been installed.

2. Buffer Mitigation
2a. Will the project result in an impact within a protected riparian buffer that requires buffer
mitigation?
❑ Yes ® No
2b. If yes, then identify the square feet of impact to each zone of the riparian buffer that requires mitigation and
calculate the amount of mitigation required in the table below.
