because there wouldn't be any preservation credit for the on-site mitigation, and provide the total mitigation credit
provided, which is 6.11 acres. Please also check the acreage of the pond area in the app and mitigation plan. Some
places it is reported as 2.87 and others it is reported as 2.86 acres.

The plan states that vegetation will consist of some, if not all, of the following. I understand the need for

What do you mean by:
h. Please amend the planting plan to include at least three of the vegetation species listed.
Do you only want three woody species?

Do you have a DWR project number I can insert into the preservation language? Or is there some other
way you would like to see it written?

Dana,
For projects that require a public notice, we do not send out requests for more information until
the comment period is over to avoid confusing the public. Understanding that it is important to
Mr. Cayton to avoid any delays in processing, listed below are the items of additional
information that we need to process the application and will request by letter once the public
comment period ends. Other additional information may be required if we receive comments
that require a response. I just wanted to give you as much time as possible to revise the
application and mitigation plan.
1. Please submit $176.78 to pay for the costs of advertising the public notice, as required
in Title 15A NCAC 02H .503(f).
2. In section D. 5. a. of the application, it states that the two existing open water pits will
be converted to herbaceous systems. Later in the same section and the mitigation plan
indicate that the area will be planted with woody wetland plant species. Please confirm
that the open water areas will be planted with woody wetland plant species.
3. We request the following information regarding the Wetland Mitigation Plan:
a. In section II. A. and B. 2. of the Wetland Mitigation Plan, please clarify that 5.68
acres of wetland preservation will be provided in addition to the 6.51 acres of
restoration, creation and enhancement proposed as mitigation for the existing
and proposed wetland impacts.
b. The Division considers the conversion of the open water areas on this site into
forested wetlands as restoration. The mitigation credit for each type of
mitigation shall be determined by dividing the type of mitigation provided by 1
for restoration, 1.5 for creation, 2 for enhancement and 5 for
preservation. Please amend the table in section II. A. to reflect these ratios.
c. Please provide a schedule for mitigation construction. The Division requires
that mitigation construction be completed within 1 year of issuance of the 401
Water Quality Certification for the project.
d. In section II. D., please indicate the source(s) of hydric soil.
e. Planting vegetation on 15 -foot centers yields 193 trees per acre, which will not
achieve the industry standard for wetland vegetation success of 260 trees per
acre after five years. The Division recommends over planting woody vegetation
(e.g. 11 ft x 11 ft spacing) to accommodate the expected mortality associated
with large scale planting.
f. Because successional species such as Acer rubrum (Maple, red) are anticipated
to colonize the restoration area on their own, please remove this species from
the planting plan.
g. The Conservation Declaration must to be amended to reflect the total
preservation area of 12.19 acres and reference the 401 Water Quality
Certification mitigation requirement and enforcement by the Division of Water
Resources.
Please amend the planting plan to include at least three of the vegetation
species listed.
The following comments are related to the ecologically -based performance
standards for the wetland mitigation plan:
i. This Office believes that a total of five vegetation sampling plots are
necessary to evaluate the success of the vegetation planting within the
proposed wetland mitigation plan. Locate one plot in the center of each
of the open water areas to be restored. Locate two plots within the
creation area. One of these should be located in the center of the
creation area east of the northern open water area and one in the
widest creation area located between the open water areas and the
enhancement area. Centrally locate one plot within the enhancement
area.
ii. This Office believes that a total of four wells are necessary to evaluate
the hydrological success of the proposed wetland mitigation
plan. Locate one well in the center of each pond. Two wells must be
located in the wetland creation area. Locate one well on the west side
of the open water areas and one on the east side of these areas.
iii. Please incorporate monitoring of the restoration and creation areas for
volunteer establishment that may jeopardize (or enhance) the success
of the planted species.
iv. This Office believes that the minimum requirement to meet hydrology
success criteria for all created and restored areas should be saturation
within the upper 12 inches of the soil for 6% of the growing season
(consecutive days) as proposed for the enhancement area.
Please let me know if you need any clarification of the information requested.
Thanks,
Jennifer
