Problems with Development and adverse effects to Wetlands:
1. Ditch diverting ground water will adversely affect hydrology in
upland review area and effect the wetlands explained by soil
scientist Sigrun Gadwa
2. How will the mosquitos be mitigated since they commonly bring
diseases and even nontoxic juvenile treatment for still affect the
other wetland insects and the food chain
3. During a major storm huge quantity of water going in and going
out causing shallow swales and gully formation which release
sediment to the wetlands and carries pollutants.
4. Very expensive to change out median of basin. Basin is limited in
sediment removal and will have increase clogging of bio retention
basin due to silt soil with Stormceptor which then releases pollutants
to the wetlands.

5. Rain Gardens should be added + green space:
Too much crowding and no green spaces. The raingardens will add
this to the development and provide aesthetic function plus they will
help reduce the frequency of maintenance on basins since they will
handle some of the water. Due to the existing high-water table
which was noted in all the experts’ reports reducing the volume of
water 30% to 40% would make sense. Too much up and down on the
water table is not good and there has been no infiltration test done
or mentioned.
6. Turtles are noted to be possible in the site by experts SLR, Sigrun,
and Mr.Theroux and We would request not using heavy machinery
that could run over them when grading and using brush hogging and
hand held saws in that area.
7. Vernal pools noted in New London side of parcel but no study has
been done for New London or Waterford how far away are they 300
ft 500 ft? and are there any on the Waterford side? They should be
protected. | think a vernal pool study should be completed.
8 Amphibian study was suggested by SLR and Sigrun Gadwa and
should be done during April/ Spring time frame to be most accurate.
9. Bulky waste pickups? How will you address this what will be the
schedule? Oil changing in driveways what will be the rules where will
they dump the oil will you provide a place for this? Pet waste pick
up rules. Pest control and poisons? These are all things that will
affect the wetlands if not managed. There is a different level of
stewardship due to renters verses owners.
