Associate Cell: 302-233-3071 MDS/ Planning, Zach Dickerson 910-798-7450 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. Response: Noted. 6. Lighting: a.

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.
