Reviewer: Max Greene
The site development plans submitted 16 September 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:
Colonial Nissan
Major site plan_(SDP201100060)
1) The proposed travel way slope is steeper than allowed by the County Ordinance. Travel
ways not adjacent to parking are not to exceed 10% slope in any direction. [18- 4.12.17.a]
2) Proposed parking lot grade changes are in excess of the allowed 5% slope. [18- 4.12.15.c]
Nissan Building Expansion Plan
A) Stormwater Management and Mitigation Plan (WP0201100074)
1) Plan appears to contain SWM information, but no fee has been processed for the review,
if this is in error on the County's behalf, please submit a copy of the "Receipt of fee
submittal" so the information can be corrected in the County database. Otherwise, please
submit an application and fee for SWM review. A SWM agreement will be required
prior to final approval.
2) Two very different Filterra details are shown on the plan sheet, one with a 3'6" depth to
outlet and one with a 1'2" depth to outlet. Existing conditions for Curb inlet ( ?) and pipe
system will be provided for review.
B) Erosion Control Plan (WP0201100074)
1) Proposed disturbed area does not appear to have adequate E &SC protection. The inlet
protection as shown requires the existing parking areas to be utilized as detention for
sediment laden storm flows. The inlet protection detail does not have overflow
protection that will result in further erosion and damage to the existing parking surface.
This office recommends showing adequate perimeter controls for the disturbed area.
Please refer to the VESCH for perimeter control structures that will meet the minimum
requirements to protect the rest of the site.

2) Please designate an area (minimum 12'x70' for one way traffic) of the existing paved
surface as the Temporary Paved Construction Entrance.
3) The construction sequence on sheet C -9 states a 48 -hour notice to arrange a pre -
construction meeting. This statement is in conflict with ES -2 of the VESCH and the first
note on sheet C -10 of the general construction notes. This office cannot guarantee a
meeting can be arraigned within 48 hours.
4) Construction narrative "Maintenance" note "B" will be corrected to match the plan sheet.
No "gravel outlet protections" are shown on the plan sheet.
5) Please show "Limits of Disturbance" to include all areas involved with site development.
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.
Current Development Engineering is available from 2:30 -4 PM on Thursdays to discuss these
review comments. Please contact Max Greene at 434 - 296 -5832 ext. 3283 or email
mgreene @albemarle.org to schedule an appointment.
[17- 204.f] An application for an erosion and sediment control plan that requires modifications, terms, or conditions to be
included in order for it to be approved shall be deemed to be withdrawn if the owner fails to submit a revised plan addressing the
omitted modifications, terms or conditions within six (6) months after the owner is informed of the omitted information as
provided under paragraph (B).
