Alan,

Attached is the existing conditions and site plan sheets from the application. Technology, argh!

Yes, stormwater runoff from the proposed development will be directed to the stormwater pond. However, it
constitutes half of the existing pond’s watershed. The portion of the property between the proposed
development and the existing housing development to the west will remain undeveloped. This area and the
adjacent developed watershed will continue to drain to the pond.

We looked very hard at trying to avoid or reduce the amount of tributary proposed to be filled, but it runs at
an angle through the footprint and the grading required for the multi-family prevented it. The original site
plan had upwards of 200 linear feet impacted. A retaining wall was added to minimize the impact to the
channel. It was reduced to just under 150 linear feet, but since the future road crossing would exceed the
threshold for mitigation, which required mitigation for the proposed impact, a few extra feet were added back
for constructability. You are correct that the project does not involve any culverts since it is fill.

Thanks,
Jennifer

Can you send be the sight plan via email. Laserfisch isn’t cooperating.

Based on what I can tell, it seems all stormwater runoff is going to the pond, so that the existing ponds watershed is
being diverted

Also the trib by the SW pond is being filled. Is it not possible to adjust /slide the building, move the SW bmp etc. to
avoid that impact. They are maximizing, but staying below threshold. I would send you a visual, but for above.

Are the impacts just fill? No culverts correct
Thanks
