Erosion & Sediment Control: Adequate
(Code Chapter 17, Article II) X Not Adequate
Y N
State standards followed, and Design Standards Manual notes and details
Adequate limits and perimeter measures out of work areas
All stages protected adequately
Adequate channels
*Building cannot be constructed with sediment control structure in
foundation. Recommend using CIP as perimeter control structure designed
per VESCH instead.
*Silt fence running down hill does not perform as silt fence but as
diversion.
*Tree protection fence will be installed 5 feet (as a minimum) outside of
actual drip edge of trees to be saved, or if not required by site plan then it
should be removed from E &SC plan and enforced with contractor as
separate item.
*please submit documentation for MS -19 compliance per VESCH.
*Please show the Albemarle County Paved construction entrance detail on
the E &SC plan.
*Please submit an easement/letter of intent from adjacent property owner
for off -site disturbance /work.
*Please include "detail C -9" in the E &SC plan.
*pipe in SCC -A appears to be in the flow path and will erode and expose
pipe over time. Please correct either pipe location or flow path of SCC -A.
*Additional comments /conditions may be forthcoming due to requested
changes to the E &SC plan
No approved SWM plan for this site on file. Please submit an application and
fee along with two SWM plans for review.
Stormwater Management Agreement will need to be updated with new
information after submittal of SWM plan.
Stormwater Management:
(Code Chapter 17, Article III) Adequate
g Not Adequate
Y N
Enough capture and treatment for on -site areas

Sealed hydrologic and hydraulic computations provided
Please submit 4 copies of the WPO plans and computations with original
signatures on seal.
Mitigation: N/A Adequate
(Code Chapter 17, Article III)
Not Adequate
Y N
m Buffers and disturbed areas adequately shown
m Adequate plantings at 2:1, or other mitigation provided
This review attempts to encompass the larger compliance questions. County staff does not assume
responsibility for any calculation or plan details, and cannot cover the intricacies of every plan submitted.
Each plan and calculation must have a professional seal and signature to assume these responsibilities.
