The Water Protection Plan for The Restoration of Montalto submitted on 22 February 2011 has received
Engineering review. The submittal cannot be approved as submitted. The following items will be
adequately addressed prior to final approval:
1. Std. & Spec 3.09 (Temporary Diversion Dike) appear to exceed the allowable drainage area for
these applications. http: / /www.dcr.vir ig nia.,gov /soil_ and_ water /documents /Chapter %203 %20 -
%203.09.pdf
2. Std. & Spec. 3.04 (Straw Bale Barriers) does not appear to meet the "Conditions where Practice
applies" and is not normally utilized in Albemarle County due to soils types and topography
resulting in failures. http: / /www.dcr.vir ig nia.gov /soil_ and_ water /documents /Chapter %203 %20 -
%203.04.pdf
3. Std. & Spec. 3.05 (Silt Fence) does not filter storm flows when installed down a slope. Please
show silt fence along a single grade elevation in order to force the sediment -laden water through
the measure and minimizing end -run erosion. All other conditions will apply.

This office recommends retaining walls instead of graded slopes in order to reduce the area of
disturbance and risk of erosion. Stone retaining walls would reflect the historic nature of the site
and reduce the risk of soil protection failure.
Once these comments have been addressed, please submit 2 copies of the revised plans,
calculations, and narratives to Current Development Engineering.
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
m .greene @albemarle.org to schedule a half hour 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included in order for it to be approved shall be deemed to be withdrawn if the owner fails to submit a revised plan addressing the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).
