Please provide descriptions for the C/CR soil profile.
2. Project Narrative states a 3-bedroom with flow reduction for a total of 270 gpd. However, soil reports is
indicating 3-bedroom with 360 gpd without flow reduction.
3. The Annual Hydrologic Loading Rate is based on the A horizon, the least restrictive layer. It should be based on
the most restrictive layer.
4. The 80th percentile precipitation data was obtained from the RDU International data for 58 years from 1948 to
2006. Although the data may be valid, The data on the website lists the data from 1946 to 2022. I am unable to

validate the information. In addition, there is a 17-year gap from 2006 to now. Precipitation rates have changed
from the past 17 years. We recommend a more up to date range for the precipitation data.
5. Ksats: Ksat 1 and Ksat2 finally readings have not reached steady state.
6. Ksats: The average measured consists of all the data collected (cm/hr). However, the average should only consist
of the data in the steady state condition.
7. The soils report does not stated the type of vegetation that is currently there and if it will change? And if it does
change, what is the temporary irrigation rate for bare soil.
