RE: Charlottesville Self Storage
Good Afternoon,
I have reviewed the latest submittal (12 /16/2011) of the Charlottesville Self Storage Plan. The plan can be
approved after the following is done:
1) All references to the Hickenbottom Agridrain riser are removed from the plan. The extended detention facility
will not function properly if there is any outlet below the 452.50 elevation (2 x WQv elevation).
2) The last line (6 of 6) of the outfall riser note is modified. This seems to be a carryover from the first plan.
Because the rim elevation is marked on the embankment detail, the riser height probably isn't necessary in
plan view. However, the height of the concrete DI -box needs to be specified.
3) An application for an ESC plan and $150 fee is provided to the county. (The current WPO number assigned to
this plan is WPO- 2011 - 00089.)
4) The ESC plan is modified in the following manner:
a) The three inch orifice is used as a ESC dewatering orifice until the site is stabilized. (In essence, the BMP
will act as a sediment basin without the wet storage until stabilization.) Draw a 5" perforated tube in
the manner found on VESCH Plate 3.14.15 on the riser detail on the ESC sheet. Add a note that says this
structure is to be installed first and the site is to be graded from south to north while keeping the 9 acres
of clean water bypassing the site for as long as possible.
b) Show the construction entrance and access path to the work area in the limits of disturbance. Provide
silt fence on the downhill side of this path.
The bond currently held by the county will be sufficient for the work proposed.
If you would like, I can leave the 4 sets submitted to the county at the front desk for you to make the above
changes. If so, please let me know the date and time you are stopping by the office.
Please let me know if you have any questions.
Thanks,
Phil

I have gone over this with Phil and tried to resolve as much as possible. This is my version of getting this
design to work with a Iyr storm and ext. det. (You will see I had to enlarge it. I could not get the smaller
footprint to work). This would address all the county engineering comments. Unfortunately, I was not able to
stay below 10,000sf, so a brief E &S plan could not be avoided.
