1.Narrative:

The proposed project will be a low impact community with the minimal necessary
infrastructure required to afford a place of wellness and enlightenment. The project is to
encompass approximately 291 acres, with a future additional 77 acre addition to the
west to gain access from US 25-70, and feature various supporting structures such as
dwellings, repurposed buildings, dining and meeting areas, an event center, and lifestyle
support facilities. Water and sewer infrastructure will be self-contained and maintained
on-site. A central water feature will be constructed in a regulated waterway.

Stormwater for the parking lot at the Reception Center will be collected by a series of
catch basins and pipes to a stormwater bioretention pond to treat and release the first
inch rainfall for water quality . The discharge of this system will be controlled by an outlet
control structure and will discharge through an 18” HDPE pipe. All runoff will be released
in the direction of their pre-development drain areas and will be released at a rate at or
lower than pre-development conditions.

All site improvements will be developed as per the Site Engineering plans and
specifications prepared by Mercer Design Group, PC, in accordance with the
requirements and specifications of Buncombe County Stormwater and Land Disturbance
Ordinances

2. Construction Sequence:

• Obtain all plan approvals and authorizations to construct, including any required
construction permits from jurisdictional agencies.
• Clear and grub only enough area to install temporary erosion control measures.
• Install gravel construction entrance pads (Mud Mats).
• Install perimeter silt fencing.
• Install diversion ditches above retaining wall north.
• Construct sediment basin (TSB) and associated outlet with dissipator.
• Develop initial site interior diversion ditches to route run-off to TSB's.
• Ensure all proposed EC measures are in place prior to any land disturbance
activities.
• Commence with site wide excavation & fill operations moving diversion ditches
as required.
• Install underground stormwater system and associated collection systems.
• After buildings, road and drives (ABC base) have been substantially completed,
obtain approval from NCDEQ inspector to remove diversion ditches and
immediately seed/mulch exposed site areas.
• Clean-out and remove remaining sediment basins/traps and restore to stabilized
condition
• Perimeter silt fencing and outlets shall remain in-place until ALL site construction
has been completed and remainder of site revegetation has been established
and approved by NCDEQ inspector.

Note: All disturbed areas, particularly exposed slopes, will, within 21 days
of completion of any phase of grading activity, be planted or otherwise
provided with temporary/permanent ground cover, devices or structures
sufficient to restrain erosion. Permanent ground cover to restrain erosion
for all disturbed areas must be accomplished within 15 working days or
no more than 90 calendar days following completion of construction or
development, whichever period is shorter, except as provided in 15A
NCAC 4B.0124(e).

Numbers in parenthesis are PF estimates at lower and upper bounds of the 90% confidence interval. The probability that precipitation frequency estimates (for a
given duration and average recurrence interval) will be greater than the upper bound (or less than the lower bound) is 5%. Estimates at upper bounds are not
checked against probable maximum precipitation (PMP) estimates and may be higher than currently valid PMP values.
