No action is necessary to
approve the Preliminary Plat, unless a majority of the Board
wishes to consider this preliminary subdivision application.
On March 26, 2009, the Planning Commission voted unanimously
to approve the Addition to Fenton Chase Preliminary Plat
subject to the following conditions:
-
The Final Plat shall be in general conformance with
the Preliminary Subdivision Plat "Addition to Fenton Chase” dated July 18, 2007,
last revised March 3, 2009, signed by John P. Foster on March 3, 2009.
-
Permission is required
from any required property owners to have the
right-of-way of Mongoose Court vacated and re-dedicated
on their property. Written permission shall be obtained
prior to Final Construction Plan approval.
-
The section of Mongoose Court that serves the original
lots of Fenton Chase shall be either accepted into the
State system for maintenance before approval of the
Final Construction Plans or bonded by the owner of the
Addition to Fenton Chase in an amount sufficient to
ensure acceptance of this section of roadway into the
State maintenance system. If such bonding is provided,
it shall occur prior to approval of the Final
Construction Plans and acceptance into the State system
shall occur prior to the issuance of any occupancy
permit for construction within the Addition to Fenton
Chase.
-
All ponds and outfall
structures shall be kept 25 feet from the property
lines. Trees, shrubs, and any other woody plants shall
not be planted on the embankment toe and abutment
contacts. This area shall be within a maintenance
easement. Tree save areas and landscaping cannot be in
these areas.
-
The emergency spillway
shall pass no less than the 100-year storm. The
emergency spillway is to be contained within the
stormwater pond lot.
-
No Stormwater Management
(SWM) facility outfall or drainageways will be directed
across the primary or reserve drainfields in the
adjacent subdivision.
-
The “C” factor, CN, Tc
and other pre-construction assumptions shall be
evaluated with the Final Construction Plan based on
values from the Fauquier County Design Standards Manual.
-
Verification
(Jurisdictional Determination) of the wetland
consultants finding by the U.S. Army Corps of Engineers
(USACE) shall be required with the first submission of
the Final Construction Plan.
-
The Final Construction
Plan shall include the following:
a.
A Virginia Certified
Professional Soil Scientist (CPSS) needs to adjust the Type
1 Soil Map soil lines onto the Final Construction Plan.
This shall be done in the field and checked for any
additional soils information to be added to the Final
Construction Plan.
b.
A signature block
shall be placed on this plan for the CPSS to sign which
states:
c.
Interpretive information from the Type 1 soil report
for each mapping unit shown on the above Final Construction
Plan shall be placed on the same sheet as the soil map.
Also a Symbols Legend shall be placed on the Final
Construction Plan to identify spot symbols.
d.
The type of primary and reserve drainfield and number
of bedrooms in the house shall be stated for each lot.
e.
The statements under Home Sites and Road
Construction shall be placed on the same sheet as the
final soils map.
f.
This final soil map will be filed in the Building
Office to be used exclusively for obtaining soils
information for this proposed information.
g.
Two (2) copies of this final soil map with CPSS
signature shall be submitted to the Soil Scientist’s Office
before the Final Construction Plan will be approved.
h.
The final signature sets shall require original CPSS
signature:
Home Sites and Road
Construction
i.
The County
recommends that no below grade basements be constructed on
soils with high water table due to wetness unless the
foundation drainage system of the structure is designed by a
Virginia Licensed Professional Engineer to assure a dry
basement and preclude wet yards and recirculation of pumped
or collected water. All exterior foundation drainage
systems shall be designed to gravity daylight without
assistance from mechanical means unless, in the opinion of
the County Engineer, the topography of the lot in relation
to the overlot-grading plan precludes grading the site to
drain the basement to daylight. All discharged water
(mechanical or gravity) must be conveyed to the subdivision
stormwater collection system and discharged through the
stormwater facilities. Drainage easements, where necessary,
shall be placed on the Final Plat. A note shall be placed
on the Final Plat stating that “Basements are not
recommended in mapping unit 416B. Basements in this mapping
unit are subject to flooding due to high seasonal water
tables. Sump systems may run continuously, leading to
possible premature pump failure.”
ii.
The following
statement shall be included on final soils map and E&S
plans:
“PRIOR TO FINAL CONSTRUCTION
PLAN APPROVAL, IT SHALL BE AGREED THAT ALL DRAINFIELD AREAS
ARE TO BE SURROUNDED BY SAFETY FENCING AND NO CONSTRUCTION
TRAFFIC SHALL CROSS NOR SHALL LAND DISTURBANCE OCCUR IN
THESE AREAS. THE FENCING OF THESE AREAS IS TO BE VERIFIED
BY COUNTY STAFF BEFORE THE ISSUANCE OF THE LAND DISTURBING
PERMIT.”
iii.
Roads built on
53C and 153B3 mapping units will need to be designed to
overcome the low bearing capacity caused by the substratum
of these soil types which are high in mica.
iv.
Due to the mica
content of the soils in the 53C and 153B3 mapping units,
these soils are highly erosive. The erosion and
sedimentation plans need to consider more filtration
practices as compared to sedimentation. Special precaution
will need to be addressed in stabilizing the cut-banks along
the proposed road.
10.
Septic drainfields shall receive a level 2 evaluation
by the County Soil Scientist’s Office, in conjunction with
the Virginia Health Department, before the Final
Construction Plan can be approved.
11.
Signage approved by the Virginia Department of
Transportation (VDOT) and the County shall be located at the
terminus of the temporary cul-de-sac (Mongoose Court)
identifying the planned interparcel connection.
