egress/ingress for the future residents of Avenue One.
There is a second “emergency” access proposed along the property frontage. This access will
be controlled by a siren activated lift gate. Aside from the proposed “future access” in Phase II
there are no additional access points proposed. Due to surrounding parcels and I-140 and
environmental conditions, additional access points are not possible.
b. No building permit for any structure shall be issued which requires NCDOT approval for a
Driveway Permit until NCDOT has issued the permit approval. Evidence of approval shall
accompany the application for the building permit.
Noted. An application for a driveway permit will be submitted.

Developable Land.
a Please note 5.7.3.E Methods for Conservation.
After the issue of conservation space was discussed independently with County Planning staff,
it was determined that the conservation resource requirement was only applicable if Class IV
soils were present. It was also confirmed that there are no Class IV soils (Dorovan, Johnston, or
Pamlico) on site and that since the site consisted of purely buildable soils, the conservation
resource requirement did not apply.
9. UDO Section 5.8 Open Space Requirements
a. Required open space for total development is 31.75-acres and a total of 33.6 acres are
proposed.
Confirmed.
b. Please detail each section of open space and the corresponding acreage on site plan.

c. Please reference Section 5.8.4 Design Standards regarding accessibility and configuration.
Noted.
10. UDO Section 6 Subdivision Design and Improvements
a. Please note that residential blocks are not to exceed 1,000 feet in length per Section
6.2.2.A.2.b.
Noted. The length of Rodanthe Avenue which was previously longer than 1,000 feet has been
revised and is now interrupted with the intersection of a cross street (.
b. Section 6.2.2.A.3.a – please detail the width of the easement of the development that is adjacent
to the I-140 corridor.
Per 6.2.2.A.3.a,”The County may require an easement as much as 50 feet in depth” The required
30’ perimeter setback currently exists along the southern edge of the property. If the County is
requiring a larger easement, we would request a clarification on that dimension. 50’ can be
accommodated with limited vegetative disturbance in most areas. There is one section of road,
approx. 375’ in length, where the proposed ROW abuts the 30’ perimeter buffer and the road
overlaps into a 50’ offset by 6’ (so, affording 42’ separation from the property boundary.) Please
advise on the County’s discretionary requirements of width and plantings in this area.
c. UDO Section 6.2.2A.7.g - Phase I has approximately 33 links and 21 nodes with a ratio of 1.57.
Phase II has approximately 31 links and 20 nodes with a ratio of 1.55.
Confirmed. Both ratios are over the required 1:40 ratio.
d. Section 6.2.2.A.15. – Cluster style mailboxes are required with paved ingress/egress.
Noted. Cluster mailboxes will be proposed in conjunction with the amenity sites.
Fire Services, Ray Griswold 910-798-7448
1. Fire Final required.
Noted.
2. Gates – require KNOX Entry system and siren activation – Both. Plan only shows one.
The primary boulevard is not intended to be gated.
3. Move fire hydrant near 25’ Storm water easement and relocate in area of Building 2-203.
Noted. A hydrant will be placed around Lot 2-203.
4. Meet all TRC Plan Review Comments.
Noted.
NHC Engineering, Galen Jamison 910-798-7072
1. A land disturbing and a stormwater permit issued by the County are required for this project in addition
to the State stormwater permit. Please submit for permits as the design is completed.
Noted. This project has received a NCDEQ stormwater permit (SW8 231111). The erosion control and
stormwater plans were submitted to the County for review 2/28/2024 with revisions re-submitted on
4/11/2023.
2. It appears the drainage patterns to the 3 culverts along Sidbury Road are being changed slightly which
may require the 100 year pre-post storm attenuation requirements with the DOT. It is recommended this
be verified with the DOT early in the design.

www.CLDeng.com
Thank you for the feedback. The analyses for these culverts was performed for the 100-year storm events
and no downstream improvements were warranted.
3. Per Section 7.8.B, 2nd bullet, please include a downstream analysis for each of the 3 existing culverts
along Sidbury Road and should they be found to be undersized, a conceptual design for the required size
with the narrative report for stormwater permitting.
A downstream analysis was provided as part of the Stormwater Narrative section of the latest
stormwater submittal to the County (4/11/2024).
4. Please give consideration to moving SCM#3 outside the 100 year floodplain.
We were not able to modify the subdivision layout to make that adjustment for Wet Detention Basin #3
or to re-route the stormwater from this area to an adjacent SCM due to the hydraulic length required.
5. Please consider locating the outfall for SCM#1 closer to the existing ditch on the adjacent parcel to the
west.
We extended the primary spillway barrel system for Wet Detention Basin #1 as far north as the layout
constraints would allow without creating a pond outfall directly adjacent to the townhomes. The
topography indicates that the pond will be able to discharge adequately in the location provided.
6. There appears offsite drainage coming from the NE parcels and the south that will/may need to be re-
routed around/through the site to avoid creating impacts to adjacent parcels. Additionally, the offsite
drainage coming from the south If so, is shall be placed in a public drainage easement sized in accordance
with NHC Stormwater Manual. Construction in the offsite drainage conveyance measures that will be
maintained by the county will need to be observed during construction by Stormwater Services and a
turnover meeting scheduled once the system is ready to be conveyed to the county. Please add a plan
note to ensure county construction observation and a turnover meeting occurs. Note, should the applicant
elect to maintain the conveyance measures themselves, the POA covenants shall indicate the operation
and maintenance roles and responsibilities for the conveyance measure.
In most locations, there are existing agricultural ditches along the property lines that collect drainage
from off-site areas. These ditches will remain and a 30’ wide public drainage easement (comingled with
the 30’ property buffer) will be placed on the property-side of the property-line ditches. There is off-site
drainage from the south that discharges onto the site before naturally being routed back off-site by the
existing agricultural ditches throughout Phase 2. This drainage pattern will be preserved and will be
placed in a public drainage easement sized per the NHC Stormwater Manual. The Phase 2 stormwater
system has not been finalized but off-site drainage into this area will be re-routed accordingly.
