Subject: Airport Drainage Calculations

 

Clay:

 

Here are the drainage calculations that we performed as part of the PER for the Airport. We decided that traditional nomograph calculations would be more appropriate and, slightly more
conservative, than H&H modeling on these small drainage areas. Please let me or Tim know if you have any questions.
