Keith,
Is there any way we will know if the revised sheets are adequate for the inspector by the end of the day today? Our
contractor has had to stop working and I would like to get them back out there tomorrow. Please let me know if there is
anything I can do to help out. Thanks.

Keith,
I received a call today from our contractor in the field letting me know that our sanitary sewer tie in elevation was off. I
have revised the necessary lines to accommodate for this. In short, the existing line was 22” higher than shown on the
plans. I had to raise SAN-01 and a portion of SAN-02 and SAN-03 to make up the difference. In raising the sanitary I also
had to raise a portion of STM-01 and STM-02 as well as make the inlets on Cedar Crest 3.5’ deep instead of 4’
deep. Please take a look at the revised plans and let me know if this is okay. Thanks for your time.
Best,

Colin,
This looks like it should be much more palatable to the church folks. Go ahead and make these changes and submit
enough sets for me to stamp and distribute.
We appreciate the effort you have gone through to continue to work on this.

Gentlemen,
I per our field meeting a week ago, I have revised the grading plan to lower the southeast pads and wall. Please see
attached file. With this plan we will be proposing to drain a portion of Lots 12, 13 and 14 to the Church property. After
reviewing the Church’s drainage area map, they actually did account for a portion of our site to drain onto them. I have
also attached the Church’s drainage area map for your reference.
Since we were looking at the grading, I would also like to proposed a 5’ private drainage easement on the northeastern
most lot (Lot 7). This will enable us to minimize the impact to the existing trees on the Church’s property. As our
grading plan stands today, we would be building a wall at the back of this lot and therefore have a high probability the
trees will die in the future.
Please let me know your thoughts and/or suggestions. Once I hear back from you I will make sure that Weekley is okay
with this and we can then move forward. I have mentioned this to them already and they were on board, but they do
want to take a final look once we have it nailed down.
Best,
Colin W. Helffrich, P.E.
