RE: Response Letter #1 for SDP-2019-037 2511 Avinity Drive
Dear Richard,
Thank you for your review of the Initial Site plan request for 2511 Avinity Drive. This letter contains
responses to County comments dated July 16' 2019. These comments were received with the approval of
the Initial Site Plan for 2511 Avinity Drive dated December 2nd 2019. Our responses are being submitted
simultaneously with the submission of the Final Site plan and are as follows:
1. Approval of the sewer extension will need to be met prior to Final Site Plan approval.
Acknowledged, remaining items for approval of the sewer extension plan were delivered
to ACSA (c/o Jeremy Lynn) on Feb. 14, 2020. The contractor is lined up and scheduled
to begin sewer installation as soon as approval is granted, thus this sewer is shown on
the site plan as "existing" because it will be completed before Site Plan construction is
begun.
2. Offsite easement for water main will be needed.
Ex. offsite ACSA water easement already exists and is now shown. New ACSA san.
sewer has been shown, this sewer easement legal reference will be added once known.
3. This area will have low water pressure. Show required fire flow can be met.
ISO fire flow requirement is 1500 gpm. Available AWWA Q20 fire flow at this area is
2371 gpm. Data obtained from ACSA flow test dated 11/28/2016 (attached).
4. Private booster pumps may be required for each building.
Acknowledged, per our calculations, pressure at the top fixtures < 20 psi, requiring
booster pumps. We have notified the architect.
5. The existing sewer to be connected to will need to be dedicated.
Acknowledged, see above, this will be provided.
