Meredith,
Please, when you have a moment, send .PDF of DCR cover letter Approving Schnabel design for Hollymead Dam
Spillway Improvement Project. Please also send .PDF of DCR Dam Alteration permit for Engineering Floodplain
Development Permit Application file –thanks Meredith.
Walter,
Just as you have with USACE NW-3 permit, please include DCR dam alteration permit and cover letter, including all
construction, inspection, monitoring requirements, etc., in the project manual. There will be no floodplain development
permit requirements issued by the County except that project must comply with USACE NW-3 permit requirements and
conditions, and VDCR-Dam Alteration Permit requirements and conditions, so by including these permit requirements
and conditions in the Project Manual, project will meet Albemarle County Code 18-30.3.13.A.1. Although 18-
30.3.13.A.1. prohibits fill within floodway zone AE, 95 cy fill will be placed per Approved Schnabel Engineering design
to improve spillways (primary /emergency) and construct a new outfall structure to meet Department of Conservation and
Recreation, Division of Dam Safety and Floodplain Management standards for a high-hazard classification
dam. Hollymead Lake Dam is a high-hazard classification dam, and project is mandated by state dam safety
regulations. All fill below BFE is permanent: 67 cy non-erodible material (sand, stone, riprap, concrete); 28 cy earth
associated with a new monolith concrete outfall structure. Ref. Attached FDP Application signed by Jeremy Young, PE,
d. 6/18/18, and ‘No Rise’ Certification to be submitted by Jeremy Young, PE, Schnabel Engineering. Thanks Walter
