The latest ESC amendment for Albemarle Place (WPO- 20 1 1 - 00093), received on 21 November 2011, has
been reviewed. This plan is the anticipated second step to the modification of the northern sediment basin
outlet structure approved with WPO- 2011 -00078 on September 29th 2011. These plans are necessary
because of delays to the completion of the 60" diversion pipe under Route 29.
I have reviewed the routings provided by the applicant. These calculations show approximately 5ft of
freeboard with the 25 -year storm which is compatible with independent calculations performed by me and
is also greater than the 3ft minimum freeboard required on sediment basins without emergency spillways
as stated in VESCH Minimum Standard 14. All other characteristics of the proposed basin also meet state
standards. Seeing no other state or local ESC standards not met by this plan, this amendment is hereby
approved.
This approval is for the temporary sediment basin condition and does not apply to the interim pond
approved in WPO- 2010 - 00023. The county has granted an extension to the grading permit (WPO -2009-
00074/WPO- 2011 - 00018) until mid- spring. It is anticipated that the 60" diversion pipe will be opened
well before then and the contractor will be able to continue construction with the original plan for the
northern basin that had been approved in April 2011. This situation will be reevaluated by the county
when the permit extension is set to expire.
