Construction Plan Review Comments #2
Dear Ms. La Mattina:
This letter and revised attached plans shall serve as our response to your comment letter dated
November 14, 2005. We have responded to your comments as follows:
Grading Plan:
Will any measures be necessary to prevent erosion at the locations where rtm-offwill flow over
the edge of pavement into the proposed drainage swale?
We have included measures for Rock Rip-Rap per attached plans as well as silt fencing and
rock berms.
Drainage Area Map:
Coordinate with the City of Coppell Parks Department regarding the construction of the proposed
drainage swale and proposed grading south of the site. Provide documentation of that department's
approval of the proposed grading work including the removal of any off-site trees. The portion of
the swale conveying drainage toward Bethel Road should be designed through Lot 2 instead of the
adjacent lot.
Per our meeting last week with City Staff, we have adjusted our grading so that it does not
affect the Park property. All drainage has been redirected through Lot 2 toward Bethel Road.
A temporary drainage swale has been designed which minimizes tree removal through Lot 2.
The proposed storm drainage within the future Bethel Road Improvements will have to be
extended further east than planned currently so that future storm drainage (which will replace
the temporary swale) from Lot 2 can tie as Lot 2 develops.
Utility Plan:
Remove the leader from the note that refers the contractor to the standard details for asphalt repair.
This note applies to the sewer line installations also.
Done.
