MEMORANDUM
TO: Ken Griffin, P.E.; Keith Marvin, P.E.
FROM: Caleb Thornhill, P.E.
SUBJECT: Coppell Road South — Street Lighting
DATE: March 12, 2009
Below is a summary of the detailed Opinion of Probable Construction Cost (OPCC) we've
prepared for street lighting on the Coppell Road South project. We assumed all conduit and pull
boxes will be installed with the construction of this project. Rick Fielding, with Oncor, indicated
that the City of Coppell would receive an approximate $2000 credit per pole. Based on this
information, here are three options for your consideration:
Option 1: Do not install any light poles or fixtures
Cost: $0
Comments: Due to economic concerns, lighting could be added later or possibly through other
funding sources.
Option 2: Install light poles at 120' spacing.
Cost: —$46,000
Comments: 120' is twice the 60' recommended spacing (As shown on Bethel Road). There
would be dark spots between lights until additional lighting was added.
Option 3: Install light poles at 60' spacing
Cost: 490,000
Comments: 60' spacing matches Bethel Road and is the recommended lighting level along the
sidewalk.
Please let me know your thoughts on these options. We are awaiting the City's direction
regarding how we should proceed.
