MEMO TO: Ron Ragland
CityManager
Attention: Scott Barnett
SUBJECT: Lakes of Coppell
We have reviewed the preliminary plat and thoroughfare planning analysis for
the Lakes of Coppell and offer the following comments.
The storm drainage criteria should be based on technical paper 40 instead of
technical paper 25.
The final design of the sanitary sewers should not have horizontal or vertical
curves, if possible.
The water line in Parkway Blvd. should be 16" diameter and the water line in
MacArthur Blvd. from Parkway to Sandy Lake should be 16" diameter.
The west ROW of MacArthur Blvd. from Sandy Lake 300 ft. north should be an
additional ten (10) feet wide for future free right-turn lanes.
The south ROW of Parkway Blvd. from MacArthur Blvd. 300 ft. west should be
an additional ten (10) feet wide for future free right-turn lane.
The north ROW for Sandy Lake Road should be an additional five (5) feet wide
for a total future ROW width of 110 feet.
The recommendation that MacArthur Blvd. be a 4-lane is not consistent with the
projected traffic volumes. MacArthur should be a 6-lane divided in final
design (4-lane divided initially is satisfactory).
