1. Zoning – PD
2. Use:
a. Residential-Single Family Attached, 50 units & Multi-Family Apartment Units
b. Please confirm the number of multi-family units proposed.
Response: Unit counts by type have been added to the site data table on sheet C-001.
3. General Comments
a. Please note PD rezoning condition 2D, “Sidewalks will be provided along both
sides of roads within the development at a width of five feet (5’), except for
portions of roads adjacent to the “Utility Easement” depicted on the MDP Master
Plan, where sidewalks will be limited to one side of the road.” -Per this
condition, it appears that sidewalks would be required at the areas indicated in
red bubble below (separate attachment).
Response: Sidewalk has been added where noted, except for the west side of Seaforth
Drive, as directed by Robert Farrell in email correspondence dated 12/4/2023 This
sidewalk would be provided with the next phase..
b. Please include total acreage of open space for this phase of the project in the site
data table
Response: Proposed acreages of open space by phase have been added to the site data
table along with required open space calculations per the Timbers at
Whiskey Branch single family project previously completed in the Planned
Development Master Plan (Timbers at Whiskey Branch notes 0.73 acres of
Open Space required for all future development).
c. Suggestion: Add a note to the plans specifying the areas labeled as Game and
Dog Park are included in the open space calculations. It may be good to just
leave them named as “Open Space” rather than stating on these plans that they’re
going to be a dog park/pickleball/bocce ball area.
Response: The open space amenities have been labeled as Open Space and included in
the open space calculations on the site data table on sheet C-001.
d. Please note that the approval of the preliminary plans must be given prior to
applying for Final Plat.
Response: Noted.
4. Parking
a. Do the townhome units have garages?
Response: Each townhome unit has a garage. Parking calculations have been revised to
account for the garage spaces on C-001.
b. It appears that parking for the multi-family portion is in excess of what is
required, but confirmation of number of multi-family/apartment units will help
determine exactly how much parking is in excess.
Response: Updated building units have been added to the site data. The parking count
has been updated on cover sheet (C-001) and site plan (C-201).
c. Suggestion: for parking that is in excess of what is required, please consider
using pervious pavement.
Response: Suggestion noted.
5. Tree Removal/Retention:
a. Tree Removal Permit TR-21-000027 has already been granted for this
development.

compliance with the standards in this section shall be submitted in
conjunction with an application for site approval (Section 10.3.6, Site
Plan) or zoning compliance approval (Section 10.3.8, Zoning
Compliance Approval), whichever comes first, approved no later than at
time of construction plan approval.
Response: Noted. Site lighting will be coordinated with and designed by Duke Energy.
b. When lighting plan is submitted, please ensure that the foot candles from the
street lights at the lot lines do not exceed 0.5, as the adjacent land is residential.
Response: Preliminary Lighting Plan included for review. Revisions needed per final site
layout.
7. Landscaping:
a. Please confirm the 17.82 acreage disturbed for this portion of the development-
this would require 267 trees be planted or retained per UDO Section 5.4.2.B.
Response: The disturbed acreage has been revised to match the updated project
boundary and required planting calculations have been updated.
b. Please note that foundation plantings are required for all portions of a building
facing parking or internal drive aisles, only multi-family in this project. This all
looks like its being met with the exception of the west side of Building #6.
Response: Foundation plantings have been added to the west side of Building #6.
8. Signs:
a. Please note that all signs are subject to section 5.6 of the UDO.
Response: This provision has been added to the site data column on sheet C-001.
b. Please submit for sign permits prior to installation.
Response: Sign permits will be submitted prior to installation by the signage consultant
or owner, near the end of the site permitting process.
