Reviewer: Max Greene
The Water Protection Plans (WP0201200023) submitted 10 April 2012 have received
Engineering Review and do not appear to meet Albemarle County minimum checklist
items for approval. Please adequately address the following comments for final approval:
A) Please show the Albemarle County Paved Construction Entrance detail on the plans.
1) Add the following note to the plan/detail: "Should the temporary construction entrance
not be maintained properly or an excessive amount of soil found tracked onto the public
roadway, then a paved construction entrance, a minimum water tap of 1" will be installed
with a minimum 1" ballcock shutoff valve supplying a wash hose with a diameter of 1.5"
for adequate constant pressure. Wash water must be carried away from the entrance to an
approved settling area to remove sediment. All sediment shall be prevented from
entering storm drains, ditches or water courses. In the event public water is not available,
then a water tanker truck with 2 pressure washers may be required by the erosion and
sediment control program administrator."
B) Sequence of construction does not reflect the project as described in the meeting of
Thursday 5th of April. The site work sequence was proposed as 4 areas to be constructed
one at a time. It was understood by this office that each area would be graded and planted
prior to beginning the next area. Please clarify proposed construction sequence. It would
be best to limit the amount of disturbed area open and any one time due to the flood plain
and the amount of micro - grading proposed prior to stabilization.
C) The County Design Standards manual has required notes that need to be shown on the
plan. Please use the following link to find the required notes for "General ", "Erosion and
Sediment Control" and "Stormwater Management ".

D) Please supply copies of all applicable permits including but not limited to the following:
U.S. Army Corps of Engineers, DEQ, VPDES and U.S. Marine Permit. Grading permit
will not be issued until proof is submitted that all applicable agencies have either
approved or waved permit requirements for this site.
Once these comments have been addressed, please submit 4 copies of the revised plans that can
be used for construction, calculations, and narratives to Current Development Engineering along
with the required review fee and transmittal form.
Current Development Engineering is available from 2:30 -4 PM on Thursdays to discuss these
review comments. Please contact Max Greene at 434 - 296 -5832 ext. 3283 or email
mjzreene @albemarle.org to schedule an appointment.
[17- 204.f] An application for an erosion and sediment control plan that requires modifications, terms, or conditions to be
included in order for it to be approved shall be deemed to be withdrawn if the owner fails to submit a revised plan addressing the
omitted modifications, terms or conditions within six (6) months after the owner is informed of the omitted information as
provided under paragraph (B).
