Subject: Trinity Landing – TRC Review – Site Plan Review
The following comments have been received for the January 23, 2019 TRC meeting:
Planning, Brad Schuler 910-798-7444
1. Please update the plan with the following general corrections:
a. Update the density calculation. Areas within the Conservation place type, AE or VE special
flood hazard areas, or CAMA Estuarine Ares of Environmental concern are subtracted
from the gross area when determining density (site data table).
b. Add the acreage of the open space provided (site data table).
c. Reference the 2016 Comprehensive Plan instead of the 2006 CAMA Land Classification.
The Comp Plan classifies the property within the General Residential and Conservation
place types (site data table).
d. It appears the parking shown for the independent living, dining/commons, and wellness
center equates to 229 spaces (page C1). This may be to the additional landscape islands
that appear in the landscape plans?
e. It appears there is an error with the sidewalk illustration east of the clubhouses. In
addition will the sidewalk be an elevated bridge/wood deck over the stormwater feature
(C2.2)?
2. A tree mitigation plan, must be submitted and approved prior to issuance of and any land
disturbance permits. The mitigation plan must illustrate the size and species of the significant
trees being removed within the development and their method of mitigation. Specifically, twice
the amount of caliper inches removed must be mitigated by either planting additional trees or by
making a payment into the County’s Tree Improvement Fund. All replacement trees must be 2-3”

in caliper at planting, or a $295 payment may be provided in lieu of installing one replacement
tree.
3. It appears the independent living building 1 is encroaching in the 200’ setback for three-story
buildings (C2). Is this portion of the building less than 3 stories or a roof overhang?
4. Please add the flood zone boundaries to the plans.
5. Please add the COD setback boundaries to the plan. Areas within the COD setback cannot be
developed unless as permitted in section 55.1-4(3) of the Zoning Ordinance.
6. Please illustrate the location of proposed street lights. Street lights shall be included at the rate
of one fixture per 500 linear feet. The rezoning plans included a site lighting plan detailing the
type of light fixture (full cut-off) and placement.
7. Please provide detailed landscape plans illustrating the number of proposed and existing
landscape species, and their sizes, that are needed to comply with the streetscape, bufferyard,
foundation, and parking lot landscaping standards.
8. The conditions of the zoning district require an intermittent berm with indigenous plantings to be
installed along the northern portion of the property as illustrated with the buffer strip section
detail of the rezoning plans.
9. Any building or land disturbing activities within the CAMA AEC OAR 575 feet from high water will
require a CAMA approval.
10. Please provide additional details regarding the proposed structure on the island. This structure
will require a flood development permit.
11. The following comments relate to the EDZD additional requirements:
a. 90% of new buildings must meet the HERO option listed within the Energy Conservation
Code of the N.C. State Building Code. Additional information should be submitted with
the building permit application.
b. One building must be constructed and certified through: LEED, NAHB Green Building
Standards, North Carolina Healthy Built Homes or Green Globes. The rezoning plan
identified the clubhouse building as the building to be built to these standards. Please
not this on the plan. Additional information should be submitted with the building permit
application.
c. Incorporate on-site nonpolluting renewable energy generation with a production capacity
of at least 5% of the project’s annual electrical and thermal energy cost (exclusive of
existing buildings), as established through an accepted building energy performance
simulation tool. The rezoning plan noted solar panels will be installed for the main
building and villas, either on the roof of each building or at another location within the
site. Please provide additional information on how this requirement will be met.
d. Please add the location of pet waste stations to the plans.
