Scott,
Thank you for the additional information. From the calculations provided, the fire flow is acceptable to reduce the side yard setback
from 15 feet to 10 feet.
Please let me know if you need anything further.
Best regards,

James -
I hope you are doing well. The fire hydrant that Tom is references will be the main fire hydrant serving the 14 TH units during a fire,
which is the fire hydrant is at the intersection of Pen Park and Rio Road, across from the Stonewater Subdivision. Below is the fire
flow requirements for the TH units. As you can see from the calculations, the NFF is 1500 GPM, and the available fire flow is over
2600 GPM. Please let me know if this satisfies your outstanding comment on the project, and please let the Planning Department
(Elizabeth Marotta) know when you have signed off on the project as acceptable.
ISO Calculations:
NFF = (Ci)(Oi)(X +P)i
NFF = (1W1.5 "(1600 ^0.5)) "(1 +(0.23 +0))
NFF = 1500 GPM
Provided Fire flow at Hydrant: 2681 GPM
Thank you.

James,
At Scott Collins' request, please refer to the attached. The fire flow requirement itself is your call.

Tom -
Can you do me a favor and send James Barber and copy me on the flow requirements and approvals for the Stonewater
Project, so we can get sign -off from the Fire Department. It appears that he wants something from you verifying the
pressures. With the 18" line and 10" in the development, this is obviously not an issue.
Thanks.
Scott

RE: Stonewater side setback reductions
Liz,
My notes from the meeting indicate I did say the side yard set back reduction from 15' to 10' was acceptable, contingent upon
verification of adequate fire flow availability. The ACSA can provide the current fire flow for the area and the developer can provide fire
flow calculations for proposed new hydrants. As always, the approval is subject to field inspection and verification.

James, I believe in the SRC meeting for Stonewater (SDP 09 -48) you verbally agreed that the reduction in side yard setbacks from 15'
to 10' was acceptable to you and that you would be providing me something in writing. I am working on wrapping up my review, and it
would be helpful if I had that from you. (It is quite possible you did email that to me and I just cannot find it, so I apologize if you did.)
Thank you!
