Attachment A
Proposed Bank Stabilization
3608 Kemble Ridge Drive, Raleigh
The purpose of this project is to stabilize and repair a streambank which has failed and to remove
concrete from an aerial sewer pipe. The project will temporarily impact a total of approximately 600
square feet of streambank on Toms Creek (Mill Creek) near 3608 Kemble Ridge Drive at 35.913900, -
78.515230 decimal degrees.
Work will entail creating a dry work area, establishing a stable toe, constructing a stable bank using coir
matting or a combination and establishing a stable segment of stream bed at the base of the bank. A
sewer bypass system will be constructed based on the state of the sewer pipe after concrete removal.
The site will be accessed from the existing sanitary sewer easement to the southwest of the site. The
temporary disturbance will occur inside the maintained easement and tree removal will occur outside
buffer zones. Erosion control measures will be installed prior to work
A "pump around" will be established to create a dry work area. Disturbed areas will be reseeded and
mulched when work is complete. It is expected that a rubber tire loader or skid steer loader and a dump
truck will be used to place the boulders, reconstruct the streambank, and stabilize the streambank.
Please see the five attached details; "pump around", temporary silt fence, temporary construction
entrance, bank stabilization, and seeding details.

•-i'` Cooperating Technical State
FEMA COOPERATING TECHNICAL PARTNER
This digital Flood Insurance Rate Map (FIRM) was produced through a unique
cooperative partnership between the State of North Carolina and the Federal
Emergency Management Agency (FEMA). The State of North Carolina has
implemented a long term approach to floodplain management to decrease the
costs associated with flooding. This is demonstrated by the State's commitment
to map flood hazard areas at the local level. As a part of this effort, the State of
North Carolina has joined in a Cooperating Technical State agreement with
FEMA to produce and maintain this digital FIRM.

NOTES TO USERS
For information and questions about this map, available products associated with this FIRM including
historic versions of this FIRM, how to order products or the National Flood Insurance Program in general,
please call the FEMA Map Information eXchange at 1-877-FEMA-MAP (1-877-336-2627) or visit the FEMA Map
Service Center website at https://msc.fema.gov. An accompanying Flood Insurance Study report, Letter of Map
Revision (LOMR) or Letter of Map Amendment (LOMA) revising portions of this panel, and digital versions of this
FIRM may be available. Visit the North Carolina Floodplain Mapping Program website at https://flood.nc.gov/ncflood,
or contact the FEMA Map Service Center.
Communities annexing land on adjacent FIRM panels must obtain a current copy of the adjacent panel as well as
the current FIRM Index. These may be ordered directly from the Map Service Center at the number listed above.
For community and countywide map dates refer to the Flood Insurance Study report for this jurisdiction.
To determine if flood insurance is available in the community, contact your Insurance agent or call the National
Flood Insurance Program at 1-800-638-6620.
Flood Insurance Study (FIS) means an examination, evaluation, and determination of flood hazards, corresponding
water surface elevations, flood hazard risk zones, and other flood data in a community issued by the North Carolina
Floodplain Mapping Program (NCFMP). The Flood Insurance Study (FIS) is comprised of the following products
used together: the Digital Flood Hazard Database, the Water Surface Elevation Rasters, the digitally derived,
autogenerated Flood Insurance Rate Map and the Flood Insurance Survey Report. A Flood Insurance Survey is a
compilation and presentation of flood risk data for specific watercourses, lakes, and coastal flood hazard areas within
a community. This report contains detailed flood elevation data, data tables and FIRM indices. When a flood study is
completed for the NFIP, the digital information, reports and maps are assembled into an FIS. Information shown on
this FIRM is provided in digital format by the NCFMP. Base map information shown on this FIRM was provided in
digital format by the NCFMP. The source of this information can be determined from the metadata available in the
digital FLOOD database and in the Technical Support Data Notebook (TSDN).
ACCREDITED LEVEE NOTES TO USERS: If an accredited levee note appears on this panel check with your local
community to obtain more information, such as the estimated level of protection provided (which may exceed the
1-percent-annual-chance level) and Emergency Action Plan, on the levee system(s) shown as providing protection
for areas on this panel. To mitigate flood risk in residual risk areas, property owners and residents are encouraged
to consider flood insurance and floodproofing or other protective measures. For more information on flood insurance,
interested parties should visit the FEMA Website at https://www.fema.gov/national-flood-insurance-program.
PROVISIONALLY ACCREDITED LEVEE NOTES TO USERS: If a Provisionally Accredited Levee (PAL) note
appears on this panel, check with your local community to obtain more information, such as the estimated level of
protection provided (which may exceed the 1-percent-annual-chance level) and Emergency Action Plan, on the
levee system(s) shown as providing protection for areas on this panel. To maintain accreditation, the levee owner or
community is required to submit the data and documentation necessary to comply with Section 65.10 of the NFIP
regulations. If the community or owner does not provide the necessary data and documentation or if the data and
documentation provided indicate the levee system does not comply with Section 65.10 requirements, FEMA will
revise the flood hazard and risk information for this area to reflect de -accreditation of the levee system. To mitigate
flood risk in residual risk areas, property owners and residents are encouraged to consider flood insurance and
floodproofing or other protective measures. For more information on flood insurance, interested parties should visit
the FEMA Website at https://www.fema.gov/national-flood-insurance-program.
LIMIT OF MODERATE WAVE ACTION NOTES TO USERS: For some coastal flooding zones the AE Zone
category has been divided by a Limit of Moderate Wave Action (LiMWA). The LiMWA represents the approximate
landward limit of the 1.5-foot breaking wave. The effects of wave hazards between the VE Zone and the LiMWA
(or between the shoreline and the LiMWA for areas where VE Zones are not identified) will be similar to, but less
severe than those in the VE Zone.

Proposed Bank Stabilization
3608 Kemble Ridge Drive, Raleigh
The purpose of this project is to stabilize and repair a streambank which has failed and to remove
concrete from an aerial sewer pipe. The project will temporarily impact a total of approximately 600
square feet of streambank on an unnamed tributary of Toms Creek (Mill Creek) near 3608 Kemble Ridge
Drive at 35.913900, -78.515230 decimal degrees.
Work will entail creating a dry work area, establishing a stable toe, constructing a stable bank using coir
matting or a combination and establishing a stable segment of stream bed at the base of the bank. A
sewer bypass system will be constructed based on the state of the sewer pipe after concrete removal.
The site will be accessed from the existing sanitary sewer easement to the southwest of the site. The
temporary disturbance will occur inside the maintained easement. Erosion control measures will be
installed prior to work.
A "pump around" will be established to create a dry work area. Disturbed areas will be reseeded and
mulched when work is complete. It is expected that a rubber tire loader or skid steer loader and a dump
truck will be used to place the boulders, reconstruct the streambank, and stabilize the streambank.
Please see the five attached details; "pump around", temporary silt fence, temporary construction
entrance, bank stabilization, and seeding details.

NOTE:
1. Seeding rates are for hulled seed unless otherwise noted.
2. Fertilizer & Limestone - rates to be applied in absense of soils tests. Recommended application rate assumes significantly disturbed site soils with little or no residual value.
3. NR means Species not recommended for this region or application area.
4. Native, warm season grasses require six or more months to germinate under optimum conditions. If they are planted in the summer, then a whole year will have to pass before they germinate.
5. Invasive designation as determined by the N.C. Exotic Pest Pant Council and N.C. Native Plant Society .
6. Sprigging is not recommended for immediate stabilization unless terrain is flat, heavymulch is applied and no other immediate stabilization method is practical.
7. Sodding for immediate stabilization - see primary stabilization charts (other information column) and Section 6.12.
8. Long term stabilization can only be accomplished with an adequate, immediate, and primary stabilization program. To achieve long term protective cover with the species listed in
this chart, the approved plan, construction sequence and maintenance schedule must include sufficient detail to assure vegetation will be established and maintained. To assure the
long term protective cover will be established, the reviewing and approving governing body may require a performance/maintenance bond.

NOTE:
With the native varieties, the seed mix should be in the range of 15 pounds per acre.
Depending on availability of native seeds adaptable to North Carolina, the percentage
of a particular variety used may be reduced or increased accordingly. Although
diversity is desirable, it is imperative that the primary crop develop and become an
effective protective cover. In addition to the native species mix, additional nurse crop
species must be included to provide immediate stabilization and an adequate ground cover.
