Reviewer: Max Greene
The road, ESC and SWM plans for East Ingleridge Farm Subdivision received on 12 June 2009,
have been reviewed. The plans will require the following changes /corrections prior to final
approval.
A site visit conducted on 7 July 2009 has determined the plans are not consistent and do not appear
to match the existing site conditions. The existing road and structures are not depicted on some of
the plans. Several "layers" appear to be on some pages and off on others. Complete review is not
possible due to condition of submittal. Additional comments will be forthcoming upon complete
and congruent submittal.
A. Road and drainage plans (SUB- 2006 - 00124, original file SUB - 2005- 00061)
1. DOT approval is required.
2. VDOT street designation sign appears to be missing from the entrance area.
3. Speed limit signage appears missing.
4. EC -1's and ES -1's are required for culvert inlets.
5. Entrance culvert pipe inlet sump area will be designed for the drainage area.
B. Stormwater Management and Mitigation Plan (WPO- 2006 - 00030)
1. A mitigation plan and fee will be submitted to the County. Mitigation plan can be attached to
the SWM plan. [Policy]
2. Plan appears to require two bio- filters on the South and west side of the stream crossing near
road station 15 +00.
3. Please extend the emergency spillway for Bio- filters 5 & 6 down the back slope of the
embankment to the existing channel or a stabilized area below the outlet pipe. [DM]
4. Please label or remove what appears to be a wall in bio - filters 7 & 8.
5. Bio - filter 6 does not appear complete.
6. Please increase the 3' riser to 4' for the 24" barrel pipe connection.
7. Mitigation areas will be adjusted to exclude the SWM outfalls.

1. Please update the E &SC narrative to current design standard requirements. [I.E. Temporary
Paved construction entrance, E &SC Notes, ]

operation is completed. Please refer to County Engineer comment #5 for stream crossings.

3. This office recommends utilization of SWM basin #1 for E &SC control instead of constructing
several different structures for the same drainage area.
