Reviewer: Max Greene
The Water Protection Plans (WP0201200023) submitted 23 January 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 submit a drainage area map for this project.
B) The drainage area appears to be over 3 acres and requires a basin by State Law; however, a Variance
request may be obtained from the program administrator. Please send a variance request and fee per
County Code [17 -104, 17- 204.B]
C) The sequence of construction appears to require clarification.
1) What is the "Contractors approved water management plan "?
2) What does "Dispose of materials offsite in accordance with contract specifications "? It is illegal to
dump off -site without an approved WPO plan for the receiving area.
3) Please give more detail about the diversion of the existing stormwater into the site.
a) When will the pipe be installed?
b) When will the existing channel be blocked?
C) Plan appears to need an exit strategy explained in more detail. This office does not
recommend diverting the stormwater into the site until stabilized. The pipe construction and
stream diversion and filling should have its own temporary construction entrance so the
contractor does not have to damage the wetland area on completion. Perhaps a phased plan
would help clarify how the site will be constructed.
Once these comments have been addressed, please submit 2 copies of the revised plans, 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 mgreene @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included in order for it to be approved shall be deemed to be withdrawn if the owner fails to submit a revised plan addressing the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).
