The fourth final site plan and comps submittal (SDP200700155) submitted 5 July 2012 have
received Engineering Review and do not appear to meet Albemarle County minimum checklist
items for approval. This review does not include a review of Erosion & Sediment Control or
Stormwater Management. Please adequately address the following comments for final approval:
Application Information
1) Due to a proposed greater than 10,000 sft of proposed land disturbance, this
project will require an approved Erosion & Sediment Control (ESC) plan. This project
will also require a Stormwater Management (SWM) plan as identified in the Water
Protection Ordinance. The WPO application previously reviewed under WP02007 -00106
has been deemed withdrawn due to inactivity [17- 204.F]. Please submit a separate WPO
plan set and $600 fee which covers ESC and SWM for this project for review. The
application for WPO plan review is available here:
