The Water Protection Plans (WP0201200037) submitted 22 June 2012 have received Engineering
Review and do not appear to meet Albemarle County nor State minimum checklist items for
approval. Please adequately address the following comments for final approval:
1. Existing basin and drainage area to basin do not appear to match previously approved plan.
Additional drainage area from Hickman Road has been added to basin since previous approvals.
Please provide a comprehensive survey to verify compliance to VSMH and show as built
conditions, and existing drainage area to basin.
2. Emergency Spillway appears to be the same elevation as Primary Spillway. This does not meet
minimum requirements per VSMH. Field survey required.
3. Please provide emergency spillway detail. County Inspector has indicated there are construction
concerns with existing spillways.
4. 100 -Year Freeboard does not appear sufficient per VSMH. Field survey required.
5. Spillway details for plan and profile do not appear to match. Field survey required.
6. Existing pond volumes need verification prior to approval. Field survey required.
7. Downstream embankment appears to be in excess of 2:1 slope. Field survey required.
8. Aquatic bench appears too deep per VSMH.
9. Storage /discharge graph of riser does not appear to be correct.
10. Tc for pre and post should not be identical. SCS 24hr storm must be used. Please revise and
provide justification.
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.
