Reviewer: Max Greene
7/14/2011 The County Engineer authorized the Chief of Current Development to interpret
18 -4.2.3 for the critical slope disturbance. The Chief of Current Development has
determined the pond is allowed per Chapter 18 of the County Code.
The Water Protection Plans (WP0201100039) submitted 25 January 2011 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:
1) A mitigation plan, application, and fee are required for this project.
2) Army CORP Permits are required for this project. Please supply copies of all State and
federal permits for this project.
3) Please show the stream buffer on the plan.
4) Please show the critical slopes on the plan.
5) Please show the drainage area for the proposed pond in a verifiable scale. Drainage area
appears to be 50+ acre.
6) Design calculations are required for the pond and sizing of outlet structures.
7) Please show a vicinity map on the plan.
8) Please show the County's "temporary Paved Construction entrance" detail on the plan.
9) Please show location and detail of stone filter dike, mentioned in narrative.
10) Please show construction details of Std. & Spec. 3.17 in accordance with VESCH.
11) Sediment trap detail does not appear correct. Stone weir center will be lower than berm
to reduce chance of failure. Please see Std. & Spec. 3.13 in VESCH for proper
construction details.
12) This office recommends routing all road drainage into pond area to help reduce the
potential for future erosion on neighboring property.
13) Limits of disturbance will include all proposed structures and channels involved in
construction.
14) This office recommends showing the driveway extended past the top of dam and to
include an area to turnaround a vehical.
E &SC Narrative:
15) Please include the total disturbed area proposed. The State of Virginia requires all

localities to report annually the total disturbed acreage approved.
16) Soils survey does not appear to match the County maps. Area of proposed dam
construction is shown as 36D and 37C3 and the driveway leading to the dam area is 36B
and 36C.
17) "Stone filter dike" is not in the VESCH and is not a "Std. & Spec. 3.09" please explain.
18) "Management Strategies" does not appear to be for this project. Please correct to be
applicable to this project.

sediment control structures. Please correct.
20) Plan mentions "Soil Borings" report. Please submit a copy of the report for the file.
Additional comments may be pending due to the above requested information.
