RE: Heritage at Spring Mill, Sections 1 & 2
Docket No. 16120017 SP
Dear Greg,
Please find enclosed 1 set of revised Final Plat, Construction Plans, Landscape Plans and O&M Manual for
Heritage at Spring Mill, Sections 1 & 2. The plans have been revised per your comment letter dated March 3,
2017. I have addressed each of your items individually with a numbering system consistent to your comment
letter.
#8&9: The SSD was turned on and shown on sheet C1.2. Please note already shown on C1.1 and the SSD
Plan sheet C6.4. Originally left off on C1.2 for plan clarify given separate sheet provided.
#11: The plans have updated the storm sewer labels.
Western Pond: Please note this was a DAM reconstruction by Banning/Temple Project. There are 2 storm
pipes. 1) Primary Lake outfall with control structure that is out in the water. 2) the second pipe is 6” SDR26
PVC pipe with a hickenbottom riser at the bottom of the lake with a valve at the outside toe of slope of dam; this
serves as a drain pipe for maintenance/inspection. This is all part of Temple project
Eastern Pond: There are two (2) pipes between west/east pond. The southern pond is a 36”RCP serving as
equalizer & outfall pipe from east to west. The second pipe is a 48” RCP that is set at the 100yr elevation
serving as an emergency overflow pipe. This is identified at the end of the Temple Drainage Report.
We are only showing the eastern pond watershed characteristics because that is all we are
amending/developing from the Master Drainage Report. This is essentially detailing that basin that was
previously planned for but not previosuly developed. Proving that actual development is inline with original
master plan. The Western pond watershed remains the same as originally designed, so those values are
maintained in the updated ICPR model.
#14: Written request previously sent to Carmel Engineering after your comment letter and before their recent
review.
If you have any questions or require additional information, please feel free to contact me at your convenience.
Sincerely,
Brandon T. Burke, P.E.
