Subject: 121Tollway Landscaping in Coppell

Steve - As requested attached for your use is a Level "E" estimate for providing landscape along the noise walls
on 121 in Coppell.
Here are a few notes with regards to the Level "E" estimate.
1.) This assumes single row of planting at 4 ft. o/c
2.) Offset from wall approx. 5 ft. to allow 4 ft. drip irrigation setback.
3.) Assumed a 7 ft. wide mulch bed with approx. 5 ft. width prepared with compost.
A portion of the walls in the vicinity of the main gantries may be too close to the frontage road to plant. For
purposes of this estimate we have included the full lengths shown on the noise wall exhibits for the walls in
Coppell. The estimate does not include the walls shown on the exhibits that are east of IH35.
Please feel free to contact either myself or Tom Kramer if you have any further questions
