Rule: 4.03(4) Drainage and Culverts
The general requirements of this section include:
o The ability of culverts to pass the 10 year 24 hour rain event.
o Are constructed to avoid collapse and erosion at inlets and outlets
o Accommodate flow from intersecting drainages.
The general requirements of this section have been adequately met in the permit. I may have additional
questions when I can verify designs through SedCad.
GCC Enerav will respond if and when additional auestions are submitted. The SedCad section has
been replaced with an updated version.

replaces the table in the permit Appendix 11 (1) King II Ditch Capacities dated March
2010 as a revised page
The information submitted with TR -25 will replace the entire contents of Appendix 11. Revised
Table of Contents pages iii and iv are attached to depict chances associated with TR -25.
10. Please confirm that Appendix 3A King II Ditch Capacities dated 2009 is no longer

the table in the permit Appendix 11 (3) King Culvert Capacities dated March 2009.

13. The table indicates that culvert C14 flows from ID -3. I was unable to locate ID -3 on the map.
Please make sure ID -3 is located on the map.
ID -3 is not shown on the map and has been removed from the table.
14. The table indicates that culvert C10 flows from D. I believe that might refer to Basin D. Please
clarify what D stands for and label it as such in the "Flows From" field in the Culvert
Capacities table.
An additional table "Flow Schedule" has been created to include in the report which lists "flows to"
locations for each ditch and culvert. The "Flows From" field has been removed

See 14 above.
