Reviewer: Max Greene
The Water Protection Plans(WP0201300011)submitted 12 February 2013 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. This plan appears to be an amendment to the WPO201100100 New Era Properties,LLC Site-
Avon Street Extended water protection plan for a waste area. Please show the previously
approved grading and make this an actual amendment to the previously approved plans.
2. Perimeter erosion control measures do not appear to meet the minimum requirements of the State
and County. Please show sediment control structures designed for the coinciding drainage areas.
Sediment traps and basins may be required for approval.
3. Diversions appear to direct concentrated storm flows over critical slopes and will require
temporary slope drains and energy dissipaters.
4. Silt fence is shown above the proposed site. Please explain.
5. Diversions need to be designed for the corresponding drainage areas and accurately depicted on
the plan sheet.
6. Rock check dams do not work as shown.
7. Please show Std. & Spec. 3.03 (CRS)on the plan sheet.
8. Limits of disturbance will encompass all erosion control measures and any other work to be
performed by this application.
9. Please show the headwater storage area for pipe inlets on the plan for construction and inspection.
Road should be a minimum 18"above the headwater depth.
10. Temporary access roads will require turn-around areas adequately sized for the anticipated vehicles
that will be utilizing this access.
11. Page 2 of 6 appears to be a boilerplate from another project. Please explain purpose of this page.
