Dear Ms. Homewood:

NR- WITER QU'
T? 'ATERI?%mc.I
We received your request for additional information, dated June 16th, 2oo9 regarding
the proposed Lynnwood Lakes Water and Sewer project. I have included a brief
response to each of your requests below. Your letter asks for the following
information:
1) Please provide a detail showing restoration of the stream crossings......
The detail was included in the original application and is labeled as `crossing
details
2) Per condition 19 of GC 3699, the temporary construction easement within
wetlands or stream crossings may only be 40 feet wide.... Please revise plans
accordingly.
The plans have been revised such that all temporary construction easements
have been reduced to 11o feet in width. The total length for temporary stream
impacts has been reduced from 228 linear feet to 189 linear feet.
3) Per condition 12 of GC 3699, the edge of the construction may not be closer
than 1o feet to a stream. The impact sheets submitted appear to indicate there
are areas where the construction corridor is beyond, or adjacent to the stream
bank. Please review this information and adjust your plans accordingly. If
adjustment is impossible, please provide a construction sequence for working
along the top of the stream bank that addresses sediment and erosion control
measures, as well as restoration of the area up completion.
The construction corridor cannot be relocated due to the alignment ofsheds
and houses and the requirement of service to the lot on impact sheets. Please
see sheet s for erosion control measures to be placed when working in this
area. Also see the coversheet forthe construction sequence of these measures
and restoration of the area after construction completion.

4) For areas of the sewer line that are parallel to the stream channel and within
wetland areas, please indicate whether any sediment and erosion control
measures will be placed outside of the temporary construction easement
shown on the plans.
All erosion control measures will be placed inside of the temporary
construction easementshown on the plans.
Please feel free to call if you have questions or require additional information.
Sincerely,
