The Water Protection Plans (WP0201200003) submitted 29 December 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) The Water Protection plans do not appear to match approved site plans. Please amend the site plans to
show all proposed work as shown on the WPO plans. WPO plans must match approved site plans prior
to final approval.
For example:
i) travel ways,
ii) new connection to route 606,
iii) retaining wall,
iv) the fence around the church site,
V) demolition of the church
2) Please clean up the random Check dams shown on sheet #14 that are not located in a Swale.
3) Please change channel #19 or the pipe inlet (242) so the stormwater flow does not erode the pipe
and/or short circuit the culvert inlet protection.
4) Drop inlets in drainage swales may need sumps to keep from washing over road during a 10 -year storm
event.
5) Pipe profiles information for pipe 242 -243 appears to be missing.
6) Acknowledging note #8 of the Borrow Sequence:
a) Channel #5 has a pipe crossing. Would this be a good time to add pipe crossings to channels #3,
#4 and unnamed channel near channel #1 for inspection and maintenance access to final design
structures?
b) There appears to be an access ramp between channels #4 and #5. Would this be a good time to
add additional access ramps to utilize the entire area after final stabilization from ARFF training
area travel way?
7) A note on sheets #12 and #13 about a diversion being maintained and reestablished needs a diversion
shown.
8) Page #17 appears to be an E &SC plan instead of a Site Plan.
9) Please provide the WPO number on sheet #12, note #12
Once these comments have been addressed, please submit 3 copies of the revised plans, calculations, and
narratives to Current Development Engineering along with the required review fee and transmittal form.
Current Development Engineering is available from 2:30 -4 PM on Thursdays to discuss these review
