RE: BALty RESIDENTIAL DEVELOPMENT EA W.
Dear Ms. oeb:
Thank. y u for the opportunity to review the above mentioned EA W. Upon review, I have several
concerns. According to NPDES rules, outletting untreated storm water runoff directly into Basin 6
would be considered an impact and would then be subject to sequencing under the Wetland
Conservatio t (WCA). Watershed acreage of all wetlands should be analyzed pre- and post-
development. A significant reduction in a watershed will cause an indirect impact to the wetlands and
may require mitigation.
Specific plans should prove no wetland impacts will occur with the construction of the boat slips, docks,
and storm sewer outfalls.
Avoidance issues will be more closely scrutinized during the WCA process, especially regarding
wetlands 3, 4, and 5. Excavating in Type III wetlands are subject to sequencing. Also, it appears that
wetlands 4 and 5 are to be impacted merely for convenience or to attain additional lots. Without
extensive knowledge of the site, I believe that wetlands 5 and 2 and possibly others could be easily
restored with small earthen dams and/or tile breaks as an alternative.
Another concern is that all proposed storm water treatment ponds will tap into the groundwater and thus
provide a direct conduit for contamination. It should also be noted that the southernmost storm water
treatment pond must be entirely separated to the to-year storm event prior to outletting into the proposed
mitigation pond.
