Re:
Request for Deferral of Pond Construction - Progress Valley Storage
Per our telephone conversation this afternoon, I am recommending on behalf of Progress Valley
Storage that construction of the storm water pond on the Dungey/Brown property be deferred
until the Spring 2009 construction season. Since there is not a compelling reason to put the pond
into service immediately (there will be no disturbance to the site that would create an additional
sediment load), it is my opinion that it would be imprudent to attempt to construct the pond this
late in the construction season, especially given the near-term forecast for rain. While it is
possible that the pond construction could be completed this fall, it is equally likely that weather
conditions could prevent its completion with the associated potential for increased sediment
loading downstream due to construction disturbance of existing vegetation. Progress Valley
Storage agrees to construct the pond within four weeks of the lifting of 2009 spring road
restrictions. If acts of nature prevent construction of the pond during this time frame, and is
confirmed by the City, the applicant will request an extension and provide a reasonable deadline
for the completion of this work.
Thank you for your consideration ofthis request.
