Specifically, how much more is to be tributary or upstream of this,ourrent line request for another interceptor in addition to June 2005 request? 2 need justification to permit the additional 12-inch gravity sewer. Even though you are not asking for more flow, you have to justify the line sizing via the expected flow under B-9. We permitted 3100+ feet of 12 and 3400+ feet of 10 going into the 1500-gpm pump station initially in 5-2005, then another 3300 feet of 12 as an interceptor in July 2005. Based on the volume that an 8 or 10 can carry at minimum slope, it seems that you are using pipe that is too large for the need and the expected upstream or tributary flow will not support 12-inch at some point. Where is the 8-inchIto serve the flow we have already permitted as we have only permitted less than 1000 feet? Perhaps we need to see the design up to this'point and the amount of yet to be permitted area with calculations to show that 10 and 12 are justified.

Certain future development areas (for example much of the land west of Sunny Point RR) are so far in the future that our plans cannot be specific other than the general land uses approved by the Town of Leland. I'm certain that you can understand that a specific plan for almost 5000 acres at one time is impractical, and we will need to maintain flexibility with market conditions as well as political realities. That being said, the conceptual plan attached does show our best estimates for almost 2500 acres, and I trust will aid you in keeping track of "where we are" and "where we are going" for this .large development project. If you have any questions or require additional information, please do not hesitate to call me. If you have specific recommendations or comments regarding the overall concept, I can make myself available for a meeting if you feel that is warranted. Thanks. S' y, David S.
