Bill,
Below is the information on the pipe across Keller Springs Road. As we discussed the town is only looking to run it as far as the concrete and plug it there so that we can extend it
in the future without removing concrete.
If you have any questions, please let me know.

Clay:
For the pipe size needed beneath the Addison Rd/Keller Springs intersection – here’s is the information you are asking for:
· The existing airport system is drained by two laterals – an 18” RCP and a 24” RCP – that are tied into the main system at the southwest corner of the intersection.
· To relieve the airport flooding, we upgraded the airport system to a 7’ x 4’ RCB (shown in red) and rerouted it beneath the Addison Road/Keller Springs intersection . It ties
back into the main trunk line (66” diam. Pipe at invert elevation of 629.47) on the north east corner.
Let me know if you have any additional questions.
