Reviewer: Max Greene
The Development Plans (WP0201400046, SDP201400039) submitted 13 May 2014 have
received Engineering Review and do not appear to meet Albemarle County minimum checklist
items for approval. The following itemized list is to assist in meeting the Albemarle County
requirements for approval:
Site Development Plan:
a. Content: The site plan must not contain the erosion control plan, stormwater
management plan, road /street plans, or mitigation plan. These must be separate
documents, to be reviewed and bonded separately, and not part of zoning documents
or zoning enforcement, or zoning letters of revision, or permanent land records, etc.
They will be removed and submitted as separate documents with corresponding
cover pages and required information.
b. Date and source of the topographic information: [18- 32.6.2] All topography should be at
least visually field verified by the designer within the last year and stated on the plan sheet.
C. Proposed slopes 3:1 slopes will have Low Maintenance Ground Cover (not Grass)
specified on plan. [Design Standards Manual, Section 8]
d. Please show the deed book and page numbers for the existing easements on the property.
e. Please show all radii for curbs.
f. Please show widths of parking islands. Minimum island width is 3' for safety.
g. Cul -de- sac /turn- around areas do not appear to meet the minimum requirements and will be
designed in accordance with the Department of Fire and Rescue.
2. Erosion and Sediment Control Plan:
a. Proposed lots #25 - #32 will be restricted from receiving building permits until the
site is stabilized and WPO inspector can release the basin for building construction.
b. A variance is required for the alternative basin design.
i. A turbidity curtain will be required in the existing pond.
ii. Additional protective measures may be required for variance approval.
iii. This is the link to the application form for the variance request:

C. Diversion should be moved back to the silt fence location to capture more of the
site work. The inlet protections over the existing storm water pipe should be blocked
in a manner that does not allow water to enter pipe (leave pipe riser sections on while
excavating area). The final Swale shaping can occur with the removal of the

sediment basin.
d. Plan appears to show significant amount of soil being removed over the existing
4.5' stormwater system pipe. How much cover does the existing pipe have to lose?
Should the existing pipe be damaged during construction, then a delay in the project
could occur while a new plan is reviewed for approval.
3. Stormwater Protection Plan:
a. Plan proposes to utilize the private pond Arber Lake in the Forest Lakes
Subdivision. Approval by the Forest Lakes Home Owners Association is required.
Please submit legal record of ability to utilize pond.
b. Not all impervious areas to the existing pond appear to be included in the
calculations. Please provide actual imperious areas to the existing pond in the
calculations (Estes Park, day care, and Shopping center).
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
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).
