Subject:
SDP200800139, Green House Coffee - Preliminary
The preliminary site plan for Green House Coffee, received on September 15, 2008, has been reviewed.
The engineering review for current development can recommend approval once the following items are
adequately addressed:
1. Current Development Engineering approves the waiver request for the use of porous concrete
pavement for the proposed parking lot. This parking lot will be treated as a stormwater
management facility. A Stormwater Management Maintenance Agreement and an easement
around and providing access to the parking lot will be required prior to approval of a Final Site
Plan.
2. Current Development Engineering recommends approval of the waiver of a minimum 20'
travelway width for the existing 14' -7" travelway. Vehicular traffic on this travelway is expected
to be very low and speeds will be minimal. The additional width being added to the front and rear
of the travelway will provide for vehicle passing, and sight distance is not a concern. This
comment will be addressed when the Zoning Administrator grants approval of the waiver.
(Approval granted by Zoning Administrator 10/6/08)
3. The applicant has also requested a waiver from the requirement of curbing of the existing
travelway and the proposed parking lot. Engineering recommends approval of the waiver for the
existing travelway because the travelway is already below the minimum 20 -foot width, and adding
curb (and possibly gutter) would decrease the width even further. The proposed parking lot will
be paved with porous concrete (Engineering has granted a surface material waiver) and stormwater
will permeate the surface rather than sheet flow off the lot. In this case, the requirement of curb
would neither hinder nor facilitate stormwater management. The proposed parking lot is also
located almost entirely within a stream buffer. The parking lot will have a pervious surface,
however, curb and gutter would not. Waiving the requirement of curb would allow for minimal
addition of impervious surface within and the least disturbance to the stream buffer. (Approval
granted by Zoning Administrator 10/7108)
4. Plans need to be stamped and signed by a licensed professional.
5. Please label the existing right -of -way and edge of asphalt of Crozet Avenue.
6. Please add sight distance triangles and easements to the entrance onto Crozet Avenue. Also add a
note that existing vegetation in front of TMP 56A1 -1 -119 needs to be trimmed to allow proper site
distance to the crest of the hill on Crozet Avenue to the north.
Mitigation is required for the disturbance within the 100 -foot stream buffer. The addition of the
parking lot, although of porous concrete, is considered disturbance. The notes on the Planting
Plan indicate that 6500 sf of buffer is disturbed. Mitigation is required at 2 times the disturbed
area. Please recalculate the required plantings and revise the Planting Plan accordingly.
The following comments will need to be addressed before a final site plan can be approved:
A Water Protection Ordinance application will need to be submitted, reviewed and approved.
9. The owner of this site needs to be a party to the Stormwater Management Maintenance Agreement
for the parking lot.
10. VDOT approval is needed for the entrance and work within the VDOT right -of -way.
