John, this plan is acceptable to me. I will send my calculation, sketch with proposed driveway with general area of
planting within buffer, and report SF, Thanks, John Grigas

Mr. Grigas,
Thanks for your call. Please accept this note as follow -up.
Mitigation is required for partial impact to landward 50' of buffer, impacts necessary to
construct a safe, compliant entrance (VDOT private entrance standards) to property located on
Dudley Mountain Rd (Rte. 706). Entrance should provide off -road storage while gate is opened.
Impact will extend from Rte. 706 to such point that driveway transitions to alignment that lies
outside the 100' buffer as it crosses the remainder of the property. Ability to safely exit SR 706,
to safely open gate and maneuver are primary objectives.
Please estimate Area of proposed driveway /entrance within the stream buffer. Calculate
mitigation required for this area (Attachedloptions). Disturbance within 50' of stream is not
necessary. Further, no mechanism exists in this situation to allow disturbance within 50' of
stream. Avoidance is possible. Alignment, improvements, and disturbance other than
plantings /pasture maintenance within 50' of the stream is prohibited.
Attached planting options guidance does not appear in current online Albemarle County Design
Standards Manual (ACDSM), but this guidance remains reliable. Please refer to it. Engineering
Review Mitigation Plan Checklist (Attached), MITIGATION ITEMS (bottom of pg) are important:
planting scheme = 2 X disturbed area.
EXAMPLE: Drive W =10' (Min width —see below). If 200' falls within landward 50' ft of buffer,
then impact =2,000 sf. 2,000 X 2 = 4,000, guides Mitigation. Mitigation/3 options /Ea. meets
requirements for a 400 SF unit (or fraction): Choose option /plantings for 10 units (4,000 sf).
This might be ten (10) 1- %2" to 2" caliper trees, or 10 evergreens (4') and ten (10) small shrubs
(15" — 18" ht). Choose native plants. Link to native plants:
hqp: / /www.albemarle.or /ng ativeplants/
Once you estimate impact, you may reduce by 100' X 10' (1000 sf) in recognition of need for
safe entrance. Please show calculations, show 1,000 sf reduction, furnish sketch that shows:
alignment of proposed drive relative to Rte. 706, and 100' stream buffer. Driveway Alignment
should exit buffer as soon as practicable. (please do not double reduction -1000 sf Max)
There is no need to appeal ordinance requirements, unless to challenge Mitigation. You may
locate a private residential entrance at existing gated field entrance, with VDOT approval.
Coordinate with Dennis Seale, VDOT, who has your number, and plans to call.
We discussed mitigation planting requirements in general. With attached information, once
calculations are performed and options considered, you may appeal if you wish, explain special
circumstance. I will relay any appeal to the County Engineer. Mitigation and Avoidance are key
strategies. I visited the site, offer what I believe is possible given constraints and importance of
ordinance requirements.
Total mitigation plantings may number 10, or less. Plantings should be located within 100' of
the stream —that is, within the stream buffer.
Please indicate general location of Mitigation plantings on a sketch showing: stream; buffer;
impact to buffer (report SF); and, proposed driveway.
This sketch will guide Mitigation Plan approval, building permit issuance, and inspections
typical of Mitigation Plans and residential construction.
A Mitigation Plan bond will be required.
Please call if you have any questions.
Thank you for your patience.

The existing gate is to the right [north] of the stream. The blue line is to the left [south] of the stream
and gate. I propose the driveway to be to the right [north] of the stream in line with the existing gate.
No tress or vegetation would be disturbed in placement of the drivewy to the left [north] of the
stream.. please reply with the redrawn blue line. Please note that the gate is located in the break in the
tree line along Dudley Mtn RD. Thanks, John Grigas

Mr. Grigas,
Thank you for speaking with me, and for your help.
My understanding from speaking with you (5pm today), from descriptions and
GIS image attached to stream buffer development form d. 2/17/15, is that you
would like to construct a driveway to a new home site on Dudley Mountain
Rd. /SR 706. Location of proposed driveway is shown in blue marker on the GIS
image, and is partially within stream buffer. I have not visited the site, but earlier
today you explained a spring gives rise to a 100 -yd stream on this parcel (TMP
89 -61A). Could you confirm that the blue line in the Google Map image, below,
indicates approx location of the proposed driveway? I have tried to mirror the
location on the GIS image left with the development form. Also, is the green line
in the second image below also a fair approximation of the proposed driveway
location?
We are comparing proposed driveway location with Albemarle County Ordinance
Sec. 17 -604 (excerpt):
<image003.jpg>
Please consider this section, and consider a slight bend in (green line) alignment
that may help keep the driveway within the landward 50 horizontal feet of the
stream buffer.
For example, a single bend may help ensure that the driveway is fifty feet from
the stream, while still ending at the home site. This could be coordinated during
construction.
Also, please explain if the proposed driveway will be paved, or gravel.
It is helpful to know that no trees will be felled or lost to construction in the
proposed location, that current land use is un- forested pasture. Please confirm if
this is correct.
Your notes on the stream buffer development Application make clear there is an
existing pasture entrance (yellow highlight, gate), that alternative entrance
locations on Dudley Mtn Rd (or Alt. driveway alignment) may require additional
length, grading, and land disturbance. Minimal additional length to maintain the
required minimal 50 -ft setback from the stream is, nevertheless, important. Please
confirm what you can.
I hope to respond to your request to develop within the 100 - stream buffer (second
image) within a day or two of receiving your response.
We appreciate your response, help, and patience, Mr. Grigas.
