I have reviewed the concept plan for the application noted above and offer the following comments for the
applicant. The comments are those that have been identified at this time. Additional comments may be added
or eliminated based on further review.
Please address for the concept layout.
1. The proposal is to have a travelway that loops around the entire site with a drop -off area near the main
entrance. Parking is also wrapped around the entire site. The drop off area poses some safety concerns
since it is too close to the entrance with another travelway veering off to the north. This drop off area should
be better defined by either a) increasing the distance from the main entrance and improving the turnaround
design or b) making it on center with the entrance with a roundabout or semi - circle.
2. 1 recommend parking to be adjacent to the bldg instead of the perimeter of the site with a travelway in
between. This will help satisfy handicap parking closer to the bldg without having to cross a travelway. If
enough parking is a concern, the bldg can be flipped 90 degrees to provide space for a parking lot.
3. The proposed biofilter is too close to the drainfield. Virginia Stormwater Design Specification No 9 states
the biofilter should be 35' from drainfield or 20' if the bottom of the bioretention is lined.
4. Is there a future plan to increase site layout? The location of the biofilter and drain field will prevent access
to a large area of the parcel.
5. Pretreatment will be required per Virginia Stormwater Design Specification No 9. The number of pre-
treatment will depend on the level. Your site does not appear to show enough room for the required number
of pre- treatment.
6. Short — circuiting of flow path from inlet to outlet of bioretention should be avoided. This will affect layout of
bioretention.
7. There is an existing 30' private RM north of site. It appears this RM will need to shift to the proposed
entrance. Please clarify.
The following will be required with the VSMP and Site Plan.
8. Note that a geotech report will be required to verify if the proposed location for the bioretention is suitable.
All report requirements can be found in the bioretention spec.
9. The notes on the title sheet refer to entrance standards. VDOT may ask for the standard commercial
entrance for the site. I recommend discussing with VDOT prior to submittal of the site plan.
10. The pavement design is subject to change. This can be determined with ADT and CBR later. For now show
an 8" for crushed stone VDOT -21 A.
