The ESC plan for the Animal Wellness Center (WPO- 2010 - 00016), received on 15 September 2010, has
been reviewed. The applicant has been notified that the site is no longer exempt from Stormwater
detention requirements because of the increased limits of disturbance. The site plan cannot be approved
until this issue is addressed. One option includes providing detention on site. If this is chosen by the
applicant, a fee for SWM review will be required. Engineering review can approve the ESC plan once the
following comments are addressed.
1. All offsite construction easements are needed before the plan can be approved.
2. Please provide the latest edition of the County's General Construction ESC notes. These notes can
be found in the design manual online.
3. Please include an " Offsite Areas" section in the ESC narrative. Please state that all offsite soil will
come from a borrow area with an active grading permit.
4. The sediment trap calculations do not match the contours on the plan. The topography is also
incorrectly drawn with regard to the 660 contours. I have attached a sketch with revised grading
that maximizes the volume of the facility given the confined space. My grading still falls short of
the required volume by 10 -25 %. Rather than require the facility to expand further south into the
area of the county pipe, engineering review will grant a variance if the upstream culvert inlet
protection was designed as a CIP -trap (per VESCH Plate 3.08 -2) with a stone weir and a volume is
equal to the shortfall of the downstream trap. Please modify the trap grading, add CI -trap grading,
and label the contours of both traps.
5. An ESC bond will be computed by the county at the time of WPO plan approval.
