Subject: [EXTERNAL] Pines at Wake Crossing DWR#20220388
Good afternoon,
I am reviewing the above referenced project, and in order to complete the review, some additional information is
required:
1) Please provide additional information on avoidance and minimization of wetlands impacts. Based on the
included FEMA letter dated December 21, 2020, there are two other options available, including removing a
culvert or adding a culvert. Option 1, removing the culvert, was stated as the best option. [15A NCAC 02H
.0502(c)]
The two other options were discussed at length with FEMA and subsequent to FEMA's letter of 21 December
2020 it was agreed Option 3 would be the best scenario to proceed with. As was explained to FEMA, Option 1,
Remove existing culvert, is not a viable option given the safety issues it would create to the public and impact to
first responders due to the creation of two dead-end roads. Removing the culvert would require removing and
i
relaying the existing public utilities such as water, power and communications from under the roadway to
UNDER the stream bed. Removing the culvert would disconnect the roadway stormwater management system
and prevent stormwater from reaching the detention basin on the north side and hence from being treated
prior to stream discharge.
Option 2, Add an additional culvert would disturb approximately the same amount of wetlands and buffer due
to the need to regrade (lower) the flood fringe to direct water into and out of the culvert, add appropriate riprap
and to provide construction access to the upstream and downstream areas.
2) Please provide additional information on how the proposed excavation of wetland will not cause a violation of
water quality standards. [15A NCAC .0506(b)(2)]
The construction techniques shall be conducted in accordance with NCDENR standards. Temporary and
additional erosion control measures shall be maintained throughout the construction process. Silt fencing will be
placed at the bottom of the slopes to deter sediment and control erosion during excavation activities.
Temporary erosion, sedimentation, and pollution controls will be installed prior to and maintained during the
entire construction duration and until final stabilization is established. Refer to Sheet 5 of the impact exhibits for
the grading and erosion control plan. Refer to Sheet 4 for the revegetation plan to stabilize the disturbed area.
No excavation is proposed below the OHWM. See attached stream section showing limits of excavation and
stream photos.
3) Please provide additional details on the buffer impacts. This area appears to be under the Town of Apex's
jurisdiction, but it is unclear what item in the Table of Uses you are proposing the activities fall under. [15A
NCAC .02B .0267]
The Town of Apex has reviewed and will be issuing a variance for the riparian buffer impacts. Upon receipt of the
variance, a copy will be sent to you. The variance is expected to be approved at the next Apex Board of Adjustment
Meeting in June. Attached is the Town of Apex Staff Report on the variance request. If the variance request is granted
by Apex, the applicant will then move to the NC EMC for approval for the Zone 1 impacts.
4) If the US Army Corps of Engineers requests any additional information, please provide the Division with a copy
of your response to the USACE. [15A NCAC 02H .0502(c)]
Will comply.
Thanks,

�o
The subject properties include portions of the platted Open Space surrounding Parlier Drive for the Pines
at Wake Crossing Phase 2 Subdivision. This subdivision sits south of Roberts Road, east of Green Level
Church Road, north of Greenmoor Subdivision, and west of Interstate 540. The Construction Drawings
for the Master Subdivision Plan, then known as The Hunt at Green Level Crossing, were approved in 2007
and platted, as The Pines at Wake Crossing in 2017. A significant portion of the subject properties lie
within the 100' Riparian Buffer required by the Watershed Protection Overlay District.
• July 16, 2007 - Master Subdivision Plan approval
• July 23, 2007 — Property sold to Toll Brothers, LLC
• August 23, 2017 - Final Subdivision Plat recorded
• August 1, 2000 - UDO Adopted
• March 23, 2021 - UDO Amendments to Section 6.1.13.E.2 Watershed Protection Overlay Districts,
Modifications by Variance, Standards
• February 8, 2022 — Property deeded to Green Level Crossing Community Association, Inc.
• April 11, 2022 - Applicant submitted variance application
VARIANCE REQUEST:
The applicant is requesting a variance from Section 6.1.11.G Uses Permitted Within the Riparian Buffer
to allow for improvements to provide corrective action to address the FEMA floodplain violation
associated with the culvert construction. The corrective action involves the removal of approximately

1,200 cy (cubic yard) from the floodplain. The excavation will lower the base flood elevation rise created
by the previously constructed road crossing over Clark Branch. The proposed remedy will create
additional flood storage adjacent to Clark Branch, which is the preferred alternative, supported by FEMA.
The FEMA violation must be remedied to meet requirements for participation in the National Flood
Insurance Program (NFIP), in which Apex is a participant. A major component of the NFIP is regulating
development in the Special Flood Hazard Area and more particularly regulating encroachments in the
floodway and non -encroachment areas.
The excavation impact will result in the temporary disturbance to approximately 0.17 acre of forested
wetland. No impervious surfaces will be introduced into Zone 1 or Zone 2. Following the excavation
activities, the disturbed area will be graded to create a reasonably smooth and uniform surface and
reseeded with the NC Piedmont Riparian Mix (Ernst Seed Mix — ERNMX-307). The construction of the
project will not necessitate the use of any specialized construction techniques. Standard construction
equipment such as cranes, excavators, dump trucks, and similar vehicles would be used for the project.
Proper erosion and sedimentation control measures would be employed throughout the project. Typical
materials and machinery will be used on -site during the construction process.
The applicant proposes to minimize impacts through construction techniques. The construction
techniques shall be conducted in accordance with NCDENR standards. Temporary and additional erosion
control measures shall be maintained throughout the construction process. Silt fencing will be placed at
the bottom of the slopes to deter sediment and control erosion during excavation activities. Temporary
erosion, sedimentation, and pollution controls will be installed prior to and maintained during the entire
construction duration and until final stabilization is established. The floodplain seed mix will allow the
area to re-establish itself. Zones 1 and 2 shall remain vegetated.
Section 6.1.11.G of the Unified Development Ordinance (UDO) reads:
6.1.11.G Uses Permitted Within the Riparian Buffer. This Section shall apply to activities
conducted within, or outside of with hydrologic impacts in violation of the diffuse flow
requirements set out in Sec. 6.1.11.E upon, a riparian buffer regulated by this Section. The
Town shall issue an approval for new development only if the proposed development will
avoid impacts to riparian buffers regulated by this Section or, if an impact to any such buffer
is proposed, in accordance with the requirements in Sec. 6.1.11.G.1 or 2 below, as applicable,
the applicant has demonstrated that: (i) the proposed activity is exempt, (ii) the proposed
activity is allowable or allowable with mitigation, and the requirements of this Section for
proceeding such designated use have been met, or (iii) a variance authorizing the proposed
activity has been obtained.
An amendment to Sec. 6.1.13.E.2-3 Watershed Protection Overlay Districts, Modifications by Variance,
Standards was approved in order to allow property owners to request a variance from the standards of
the Watershed Protection Overlay Districts regardless of when the property was purchased. The
previous standard required the Board of Adjustment to find that the property owner did not purchase

the property after Sec. 6.1 was codified with the adoption the Unified Development Ordinance in 2000.
Below are the March 23, 2021 amendments to Sec. 6.1.13.E.2-3:
6.1.13 Watershed Protection Overlay Districts, Modifications by Variance
E) Standards
2) In order to approve an application for a variance permit, the Board of Adjustment
shall make a finding of fact as to whether the standards of Sec. 2.3.8D.1-3 Variance
permit, Standards are met.
3) The Board of Adjustment shall make a finding of fact as to:
a) whether the variance is in harmony with the general purpose and intent of
the Town's Watershed Protection Overlay Districts and preserves its spirit;
and
b) whether in granting the variance the public safety and welfare have been
assured, water quality has been protected and substantial justice has been
done.
STANDARDS FOR VARIANCE REQUESTS:
To approve a variance permit, the Board of Adjustment must find that all the following standards as
listed in Sec. 2.3.8(D) are being met. In the alternative, to deny the variance permit, the Board of
Adjustment must find that any of the following standards are not being met:
1) Unnecessary Hardship. Unnecessary hardship would result from the strict application
of the ordinance. It shall not be necessary to demonstrate that, in the absence of the
variance, no reasonable use can be made of the property.
2) Hardship Results from Peculiar Conditions. The hardship results from conditions that
are peculiar to the property, such as location, size, or topography. Hardships resulting
from personal circumstances, as well as hardships resulting from conditions that are
common to the neighborhood or the general public, may not be the basis for granting a
variance.
3) Not Result of Action by Applicant. The hardship did not result from actions taken by the
applicant or the property owner. The act of purchasing property with knowledge that
circumstances exist that may justify the granting of a variance shall not be regarded as a
self-created hardship.
4) Consistency with the UDO. The requested variance is consistent with the spirit, purpose,
and intent of the ordinance, such that public safety is secured, and substantial justice is
achieved.

STAFF ANALYSIS:
The Final Subdivision Plat for The Pines at Wake Crossing Phase 2 was recorded on August 23, 2017. The
existing structure has remained since its original construction serving residential development. The
property was deeded to applicant February 8, 2022. The applicant purchased property subject to the
Watershed Protection Overlay District. The Watershed Protection Overlay District has been in place
since the adoption of the Unified Development Ordinance (UDO) August 1, 2000. The UDO was
amended by Town Council on March 23, 2021 to allow for owners of property located within riparian
buffers to apply for a variance. The applicant filed the variance petition on April 11, 2022 in an effort to
remedy the FEMA violation. Should no improvements be permitted on the subject site then it will
remain in violation of FEMA regulations, Town of Apex Floodplain regulations, and may not meet
requirements for participation within the NFIP. According to Water Resources staff, the proposed
improvements are the overall least impactful solution for mitigating the violation of FEMA regulations.
If the variance is granted, the applicant will then move to the North Carolina Environmental
Management Commission (NCEMC) for further approval for Zone 1 impacts.
