Coordinate with City staff the horizontal and vertical
location of the storm drain outfall at Moore Road.
There are problems at Moore Road which need to be
worked out. There are problems tying in the proposed
48M RCP and 60" RCP into the existing drainage system
because of the 30" water line. Robert suggested
tying in the proposed 48" RCP and 60" RCP into a
junction box south of the 30" water line and running a pipe
(as large as necessary) into the existing drainage system.
The 30" water line would need to be lowered in this
area. This problem will be looked into further.
Identification of known utilities within project limits
and potential conflicts. Utilities have been identified,
but potential conflicts have not been resolved.
Impact of street grades and storm drain improvements
on the existing 30" water line. The locations of the
valves will be the same, but the locations of the risers
will be different.
g. Location, size, and impact of thrust blocking for relocation.
h. Evaluate alternative locations for 24" water line.
Determine the location of existing 8" and 16" water lines
within Sandy Lake Road. The 16" water line needs to
be moved (vertically) in the same places as the 30" water line.
j. New fire hydrant locations.
k. Geometry of median openings, left mm lanes and driveways.
1. Traffic signaH?ation layout.
m. Layout of street lighting.
*1. Locate and verify Lone Star Gas line. (GDS)
2. Detail of riser extension (obtain DW'U approval). (GDS/R.IM)
3. Approval of alley approach. (RJM)
