If not, I will update the plans based on your comments below. Thanks, Dave David K. Kochalka, P.E.

Include a copy of the plat with the revised easement locations. 2. Provide detail for the manhole specifying a 30" rim. The cover will need to be purchased from the Town of Addison. We are selling them at our cost. Bass & Hayes said that we had to purchase 75 up front in order to make the switch to the 30" ring & covers and still retain our logo. We have sold 13, but are anxious to sell the others. 3. The valve placements we discussed. 4. Please specify to center one joint of water pipe over the existing sanitary sewer in accordance with 290 TAC on the services and fire hydrant relocates along Addison Road. Gordon Robbins with the Fire Department is coming over tomorrow to review the revised layout. I will let you know the outcome. If you have any questions, please let me know.

Does this mean the plans are approved with no comments? David K. Kochalka, P.E.

It is funny how their version seemed to work in their favor. Anyway, I have learned to check them before I approve them. It was something I had meant to check before I sent it to the third party, but it did not happen. They did not catch it on another project, but I could tell just by looking at the volumes that the equations were incorrect. I guess I could have plugged it into mine, but I did not think about it when I asked you for the spreadsheets. This one is fine though. We have been working on re-writing our storm sewer ordinance. We have modeled it on Carrollton, but I am going to change their detention requirements to include the modified rational for under 100 acres. That would cover any existing or future project in Addison with the exception of Vitruvian. Now that you know more than you probably ever wanted to... Thanks, Clay Barnett, P.E.

I just wanted to verify that it is the modified rational method and not incorrectly calculated. I guess I could have crunched the numbers, but this certainly makes it easier.
