Noelle, Please submit a proposal for the White Rock and Southeast Addison Basins. Please set the amount at a not-to-exceed of $23,500. Although these are projected to be $18,000, I do not want to run out of funds and be unable to finish. If we have funds remaining, we can begin the North Addison Basin. I think the estimate on it may be high and we may be able to do all three for the total amount. We do need to complete the project by Sept. 31 if at all possible. Thanks, Clay Barnett, P.E.

Take a look and let me know if you have any questions. If one of the larger basins has a higher priority than the smaller ones, we can always start the inventory on it and continue until we run out of funds – its completely up to you. Have a great weekend!

I have attached the proposal I prepared in July that outlines the proposed cost to complete the inventory for 1-2 basins. My original proposal is based on a budget of $30,000; however as shown below and in Attachment B, we could complete the inventory for some of the smaller basins if your available budget funds are smaller. Cost Estimate Basin Low High Airport $13,000 $21,000 Farmers Branch $15,000 $24,000 Middle DNT $15,000 $24,000 N. Addison $9,000 $14,000 Rawhide Creek $29,000 $46,000 SE. Addison $7,000 $11,000 White Rock $4,000 $7,000 Also, Walter mentioned that you are going to be meeting with a GIS consultant tomorrow to discuss updating the Town’s Public Works GIS. I have a decent amount of experience implementing public works GIS systems, so please let me know if you have any questions. I have training tomorrow, but I am happy to send one of the GIS analysts in our group to sit in on the meeting if you want. Either way, please let me know if we can help out with your GIS implementation in any way. As always, let me know if you have any questions.
