BARCLAY PLACE

Georgetown Road Near Hydraulic Road
Barclay Place is a 124 unit apartment complex to be built on
a 4. 8 acre site between Westgate Apartments and Georgetown Court.
Entrance will be from Georgetown Road via a 220' private road which
will also serve Old Dominion Day School. This road has been
completed except for surface treatment. The site plan has been
approved by the Albemarle County Planning Commission, subject to
staff approval in several technical areas . While the approved
site plan includes several different uses for various parts of the
former Mowinckel Estate, this grading plan is limited to the
construction of Barclay Place.
The site is part open and part wooded, with several large trees
in the otherwise open area. Parking and buildings have been located
on the site so as to preserve as many of the trees as possible. In
order to permit minimum grading, thereby saving trees and topsoil,
the buildings are to be matched to the sloping site by making
them two stories high on the uphill side and three stories high on
the downhill side. The middle stories will be a few steps above
grade in the front, and the lower stories will generally be at
walk out level on the downhill side. In addition, we will grade
so that there is a swale a few feet away from the buildings on the
uphill side, so water will drain away from all sides of the buildings.
Water from the parking lots will be collected in catch basins
and curb inlets connected in two drainage systems. One storm
drainage system will connect to an existing storm sewer line that
has been extended through Georgetown Court to the southwestern side
of the property. The other will discharge to the southeast into
a wooded area. Ultimately, this wooded area will be developed as
Solomon Court Phase III, and the storm sewer will be extended through
the new development. For the present, the Barclay Place storm
sewer system in this direction will terminate in rip-rap which
will be placed just below Catch Basis "E" on the Barclay Place site
plan.
No major erosion problems will be created by the grading.
There is no large flow of water across the property, as the uphill
(northern) corner is within 50' of the top of the watershed. There
is Ito be a jogging path around the edges of the property, and to
minimize washing across adjacent property and to prevent washing of
the surface material (wood chips) from the path, we plan to elevate
the path slightly and make a slight depression just uphill from it.
This elevated path will serve as a diversion structure, both during
and after construction, to direct runoff from the site to the storm
sewer system. During construction, we will place straw bale barriers
or brush dams to filter the runoff before it leaves the site. The
diversion structure around the edges of the site and the sedimentation
barriers will be put into place as soon as grading is started.
Similar barriers will be used to filter water entering the storm
drainage system until such time as the site is seeded.
Ingress and egress for the job will be via the private drive
from Georgetown Road, and a stone pad will be placed to clean the
wheels of the vehicles before they leave the job site.
