Subject: Dogwood Stream Restoration DWR#20220887

Good afternoon!

I am beginning my review of the above referenced project, and some additional information is required to complete the review:

1. If the US Army Corps of Engineers requests any additional information, please provide the Division with a copy of your response. [15A NCAC 02H .0502(c)]

We have not received a request for additional information from the USACE. If received, we will copy you on the response as requested.

2. Typically I see a 5-year monitoring plan, especially when riparian buffer is being replanted. Please provide additional information on why only a year (plus two bankfull events) monitoring
plan is being proposed. [15A NCAC 02H .0502(c)]

As we discussed, please see the attached Revised Monitoring Plan with visual vegetation monitoring annually for three years after planting.

3. Additionally, I would like to see more details regarding what will be planted in the buffer. Under “Species Selection” of the planting plan, it states that a written list of the actual
species installed must be delivered to the designer for review before final approval. Will a copy of this list, and a map of plantings, also be provided to DWR? [15A NCAC 02B .02H .0502(c)]

Attached is an updated planting plan from the construction drawings that lists the number and species that will planted.

Thanks,

Colleen Cohn

REVISED MONITORING PLAN > DOGWOOD
2905 Meridian Parkway, Durham, NC 27713 / 919. 361. 5000 creating experiences through experience
MONITORING PLAN
The monitoring plan to evaluate the success of the Site is based the U.S. Army Corps of Engineers (USACE) Stream
Mitigation Guidelines (2016) and the North Carolina Ecosystem Enhancement Program (NCEEP) Monitoring
Requirements and Performance Standards for Stream and/or Wetland Mitigation (November, 2011). Monitoring of the
stream and site will occur for one (1) full year, and then after two (2) bankfull events. A monitoring report will be
generated for each monitoring year documenting the activities at the Site. After one year and two bankfull events,
visual monitoring of the buffer will continue annually to ensure vegetation survival for three years after planting.

STREAM MONITORING
Stream geometry will be considered successful if the geometry, profile, and sinuosity are stable or reach a dynamic
equilibrium. It is expected that there will be minimal changes in the designed cross sections, profile, and/or substrate
composition. Changes that may occur during the monitoring period will be evaluated to determine if they represent a
movement toward a more unstable condition (e.g. down cutting, or bank erosion) or are minor changes that represent
an increase in stability (e.g. settling, vegetative changes, coarsening of bed material, etc.). Deviation from the design
ratios will not necessarily denote failure as it is possible to maintain stability and not stay within the design geometry.

BANKFULL EVENTS
The occurrence of bankfull events within the monitoring period will be documented using a crest gage and photographs.
A crest gage will be installed which will record the highest watermark between site visits. The crest gage will be checked
each time there is a site visit to determine if a bankfull event has occurred. Photographs will be used to document the
occurrences of debris lines and sediment deposition on the floodplain during monitoring site visits. The monitoring
period must cover at least three (3) bankfull events.

CROSS SECTIONS
A total of four (4) cross sections will be installed after construction of the Site and will be surveyed as part of the As-
built survey, one (1) year after construction, and then after two (2) bankfull events. Each cross section will be marked
on both banks with permanent pins/monuments to establish the exact transect used. A common benchmark will be
used for the cross sections and it will be consistently used to facilitate easy comparison of year to year data. The cross
section survey will include points measured at all breaks in slope, including top of bank, bankfull, inner berm, edge of
water, and thalweg, if the features are present. There will be two (2) riffle cross sections and two (2) pool cross sections.
Pebble counts shall be completed at each of the riffle cross sections. Photographs shall be taken at each cross section
with one photograph facing each bank.

VISUAL MONITORING
Visual monitoring shall take place along the entire stream reach twice annually during the monitoring period to
document any lateral movement, structure failure, aggradation/degradation, invasive species, headcuts, or beaver
activity. Visual monitoring will also be required in the buffer to document any excessive mortality, low stem density,
encroachments, or invasive species.

LONG-TERM PRESERVATION MECHANISM
The long-term preservation mechanism will be in the form of buffer rule legislation provided in the Jordan Lake Water
Supply Watershed Buffer Rule, 15A NCAC 02B .0267. The Town of Apex will manage the buffer and enforce
requirements of the buffer rule to provide long-term assurance to the success of the project. The Division of Water
MONITORING PLAN > DOGWOOD
creating experiences through experience 2 of 2
Resources shall periodically inspect the Town’s buffer program to ensure that requirements of the buffer rules are being
implemented and enforced.

SUCCESS CRITERIA
Success criteria will determine if the restoration project is meeting its prescribed goals for the project. A determination
will be made regarding the success of the project following the collection and evaluation of ecological and physical
monitoring data, photographs, site observations, and the performance of the streams during storm events. Monitoring
components that will be evaluated include vegetation survival, channel bed and bank stability, and in-stream structure
performance.

STREAM SUCCESS CRITERIA
Channel stability will be reflected in the surveyed permanent cross sections, evaluation of bank stability and cover,
evaluation of in-stream structure performance and to a lesser degree pebble counts compared to the as-built and any
previously collected monitoring data. The general trend should reflect a stable or slightly decreasing riffle cross sectional
area whereas pools may increase and yet be considered relatively stable. Normally the constructed channel will adjust
(especially in a sand dominated bed) but it will need to function without significant degradation (bed scour), aggradation
(mid-channel bars), or bank erosion.

The Bank Height Ratio (BHR) as determined by cross section surveys, shall not exceed 1.2 and the Entrenchment Ratio
shall be no less than 2.2 within the restored reaches. The stream shall remain stable over the first year, through two
bankfull events, as indicated by visual surveys and cross sections.
