IV. PROJECT INFORMATION
1. In the space provided below, briefly summarize how the stormwater runoff will be treated.
The site stormwater will be collected via a combination of overland flow, a curb and gutter system, storm
sewer biping and inlets, and culverts and ditches. Stormwater management for the site will be provided by
two sand filters. The receiving water for this site is Stones Creek which outfalls into the New River, an SA
water. This is a modification of existing Permit SW8 080313. This project modifies Draina g Areas 6 and 9.
2. a. if claiming vested rights, identify the supporting documents provided and the date they were approved:
❑ Approval of a Site Specific Development Plan or PUDApproval Date:
❑ Valid Building Permit Issued Date:
❑ Other: Date:
b.If claiming vested rights, identify the regulation(s) the project has been designed in accordance with:
❑ Coastal SW —1995 ❑ Ph II — Post Construction
3. Stormwater runoff from this project drains to the White Oak River basin.
4. Total Property Area: 7.6 acres
5. Total Coastal Wetlands Area: 0 acres
6. Total Surface Water Area: 0 acres
7. Total Property Area (4) —Total Coastal Wetlands Area (5) —Total Surface Water Area (6) = Total Project Area':
7.6 acres
Total project area shall be calculated to exclude the following: the normal pool of impounded structures, the area
between the banks of streams and rivers, the area below the Normal High Water (NHW) line or Mean High Water
(MHW) litre, and coastal wetlands landward from the NHW (or MHW) line. The resultant project area is used to
calculate overall percent built upon area (13U& Non -coastal wetlands landward of this NHW (or MHW) line may be
included in the total project area.
8. Project percent of impervious area: (Total Impervious Area / Total Project Area) X 100 = 72
9. How many drainage areas does the project have?3 (For high density, count 1 for each proposed engineered
stormwater BMP. For lore density and other projects, use 1 for the whole property area)
10. Complete the following information for each drainage area identified in Project Information item 9. If there
are more than four drainage areas in the project, attach an additional sheet with the information for each area
provided in the same format as below.

Infiltration Basin Operation and Maintenance Agreement.
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
Important maintenance procedures:
The drainage area will be carefully managed to reduce the sediment load to the
infiltration basin.
Immediately after the infiltration basin is established, the vegetation will be
watered twice weekly if needed until the plants become established (commonly
six weeks).
No portion of the infiltration basin will be fertilized after the initial fertilization
that is required to establish the vegetation.
The vegetation in and around the basin will be maintained at a height of
approximately six inches.
After the infiltration basin is established, it will be inspected once a quarter and within
24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal
County). Records of operation and maintenance will be kept in a known set location
and will be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

Infiltration Basin Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
Important maintenance procedures:
The drainage area will be carefully managed to reduce the sediment load to the
infiltration basin.
Immediately after the infiltration basin is established, the vegetation will be
watered twice weekly if needed until the plants become established (commonly
six weeks).
No portion of the infiltration basin will be fertilized after the initial fertilization
that is required to establish the vegetation.
- The vegetation in and around the basin will be maintained at a height of
approximately six inches.
After the infiltration basin is established, it will be inspected once a quarter and within
24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal
County). Records of operation,and maintenance will be kept in a known set location
and will be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

Infiltration Basin Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
Important maintenance procedures:
— The drainage area will be carefully managed to reduce the sediment load to the
infiltration basin.
— Immediately after the infiltration basin is established, the vegetation will be
watered twice weekly if needed until the plants become established (commonly
six weeks).
— No portion of the infiltration basin will be fertilized after the initial fertilization
that is required to establish the vegetation.
— The vegetation in and around the basin will be maintained at a height of
approximately six inches.
After the infiltration basin is established, it will be inspected once a quarter and within
24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal
County). Records of operation and maintenance will be kept in a known set location
and will be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

Important maintenance procedures:
— The drainage area will be carefully managed to reduce the sediment load to the sand filter.
— The sedimentation chamber or forebay will be cleaned out whenever sediment depth exceeds
six inches.
— Once a year, sand media will be skimmed.
— The sand filter media will be replaced whenever it fails to function properly after maintenance.
The sand filter will be inspected quarterly and within 24 hours after every storm event greater than
1.0 inches (or 1.5 inches if in a Coastal County). Records of operation and maintenance will be kept in

Sand Filter Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a log in a
known set location. Any deficient BMP elements noted in the inspection will be corrected, repaired or
replaced immediately. These deficiencies can affect the integrity of structures, safety of the public, and
the removal efficiency of the BMP.
Important maintenance procedures-
- The draina& area will be carefully managed to reduce the sediment load to the sand filter.
- The sedimentation chamber or forebav will be cleaned out whenever sediment -depth exceeds
six inches.
- Once a year, sand media will be skimmed.
- The sand filter media will be replaced whenever it fails to function properly after maintenance.
The sand filter will be inspected quarterly and within 24 hours after every storm event greater than
1.0 inches (or 1.5 inches if in a Coastal County). Records of operation and maintenance will be kept in
a known set location and will be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall be repaired
immediately.

Filter Strip, Restored Riparian Buffer and Level Spreader
Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
Important maintenance procedures:
— Immediately after the filter strip is established, any newly planted vegetation
will be watered twice weekly if needed until the plants become established
(commonly six weeks).
— Once a year, the filter strip will be reseeded to maintain a dense growth of
vegetation
Stable groundcover will be maintained in the drainage area to reduce the
sediment load to the vegetation.
— Two to three times a year, grass filter strips will be mowed and the clippings
harvested to promote the growth of thick vegetation with optimum pollutant
removal efficiency. Turf grass should not be cut shorter than 3 to 5 inches and
may be allowed to grow as tall as 12 inches depending on aesthetic requirements
(NIPC, 1993). Forested filter strips do not require this type of maintenance.
Once a year, the soil will be aerated if necessary.
Once a year, soil pH will be tested and lime will be added if necessary.
After the filter strip is established, it will be inspected quarterly and within 24 hours
after every storm event greater than 1.0 inch (or 1.5 inches if in a Coastal County).
Records of operation and maintenance will be kept in a known set location and will be
available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set Iocation. Any deficient BMP elements noted in the inspection will'be
corrected, repaired or replaced immediately.. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP..
important maintenance procedures:
— Immediately after the filter strip is established, any newly planted vegetation
will be watered twice weekly if needed until the plants become established
(Com.monly six weeks).
— Once a vear, the filter strip will be reseeded to maintain a dense growth of
vegetation
— Stable groundcover will be maintained in the drainage area to reduce the
sediment load to the vegetation.
— Two to three times a year, grass filter strips will be mowed and the clippings
harvested to promote the growth of thick vegetation with optimum pollutant
removal efficiency. Turf grass should not be cut shorter than 3 to 5 inches and
may be allowed to grow as tall as 12 inches depending on aesthetic requirements
(NIPC,1993). Forested filter strips do not require this type of maintenance.
Once a year, the soil will be aerated if necessary.
Once a year, soil pH will be tested and lime will be added if necessary.
After the filter strip is established, it will be inspected quarterly and within 24 hours
after every storm event greater than 1.0 inch (or 1.5 inches if in a Coastal County).
Records of operation and maintenance will be kept in a known set location and will be
available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

permittee and the project shall be subject to the following specified conditions and
limitations:
■1DI*1 Ltlil&3ri1:I1711091.9
This permit is effective only with respect to the nature and volume of stormwater
described in the application and other supporting data.
2. This stormwater system has been approved for the management of stormwater
runoff as described in Sections 1.7 and 1.8 of this permit. The eight stormwater
controls labeled DA1, DA2, DA3, DA5, DA6, DA7, DA9 and DA-10 have been
designed to handle the runoff from a total of 99,550 ft2; 23,705 ft2; 53,429 ft2;
16,553 ft2; 142,320 ftz; 165,414 ft2; 79,902 ft2; and 111,453 ft2; of impervious
area, respectively.
3. The overflow from each infiltration basin and sand filter covered by this permit
must be directed to a 50-foot level spreader and vegetated filter strip. The
underdrain discharge from SF #3 in DA 9 and SF #4 in DA 10 is directed into a
level spreader and 50' vegetated filter strip, designed per Section .1008 (0 of the
stormwater rules to achieve effective infiltration of the underdrain runoff.

4. The runoff from all built -upon area within each permitted drainage area of this
project must be directed into the appropriate permitted stormwater control
system.
5. Each infiltration basin and sand filter will be limited to the treatment of that
amount of built -upon area indicated in Sections 1.2, 1.7 and 1.8 of this permit, and
as shown on the approved plans. The built -upon area for future development is
limited to 3,160 square feet within DA 5.
6. Projects covered by this permit will maintain a minimum 50-foot-wide vegetated
buffer adjacent surface waters, measured horizontally from and perpendicular to
the normal pool of impounded structures, the top of bank of each side of streams
and rivers, and the mean high water line of tidal waters.
