High Density Commercial Sand Filter Project
Onslow County
Dear Mr. Baker:
Dee Freeman
Secretary
The Wilmington Regional Office received a complete, modified Stormwater Management Permit Application for
USMC — AAV Company on July 9, 2012, Staff review of the plans and specifications has determined that the project,
as proposed, will comply with the Stormwater Regulations set forth in Title 15A NCAC 2H.1000 and Session Law
2008-211. We are forwarding Permit No. SW8 080907 dated October 1, 2012, for the construction, operation and
maintenance of the BMP's and built -upon area associated with the subject project.
On August 5, 2009, the Governor signed Session Law 2009-406. This law impacts any development approval issued
by the Division of Water Quality under Article 21 of Chapter 143 of the General Statutes, which is current and valid at
any point between January 1, 2008, and December 31, 2010. The law extends the effective period of any stormwater
permit that is set to expire during this time frame to three (3) years from its current expiration date. On August 2,
2010, the Governor signed Session Law 2010-177 which grants an extra year for a total of four (4) years extension.
Accordingly, Stormwater Permit SW8 080907, which was set to expire October 8, 2018, is now in effect until July 2,
2020.

Project Description/General Information
This document is to serve as a modification to an existing permit (SW8 080907)
for the MCB Camp Lejeune — AAV project. The existing permit accounted for five sand
filters and associated level spreaders, flow splitters and filter strips. This modification is
the result of two changes to drainage area 5, outlined below:
1. The proposed impervious parking lot within drainage area 5 has been
reduced due to existing sanitary sewer lines which conflicted with the
proposed parking lot location. As a result, the original proposed impervious
area of 23,217 sf has been decreased to 15,694 sf (Attached Sheet C-3 and
C-4) within drainage area 5 however the proposed Sand Filter # 5 and its
associated level spreader were built as permitted under SW8080907.
2. It was determined that the bypass flow could not be routed to the intended
discharge location due to impacts to existing utilities and a oil/water separator
outlet. In accordance with SL2006-246, the bypass outlet will be re-routed to
the existing stormwater level spreader which is appropriately designed to
handle the bypass flows from the site.
At the time of this report, all of the site work has been completed except for the
re-routing of the bypass pipe to the level spreader.
The AAV Company Project is located off Courthouse Rd. on Camp Lejeune
Marine Corps Base in Onslow County, NC. Although no specific tract can be identified
with this project (the base in one large, contiguous property) the area being disturbed for
the project is approximately 6.92 acres. The project will be avoiding impacts of
wetlands.

Identif
Y Project Involvement
This project is a part of the White Oak River Basin, and is currently not subject to
any buffer rules. The site is approximately 2,500 feet from the New River and
approximately 417 feet from Courthouse Bay, just outside of Sneads Ferry, NC and is
located in Onslow County, which is as of October 1, 2011 is subject to the Coastal
Stormwater Rules. However, the original permit for this project was covered by the
NPDES Phase II Stormwater Rules. The NCDWQ Stream Classification of Courthouse
Bay is SA, HQW and its NCDWQ Index Number is 19-36. The Stream Classification of
the New River is SA, HQW and its Index Number is 19-27.

The proposed project stormwater plan will meet the requirements of detaining the
3.7 inch rainfall event for a period of approximately 2 days, per the requirements by the
State as referenced from the DWQ Stormwater Manual, July 2007. The Stormwater
Design is High Density, Coastal Stormwater. Five sand filters are proposed to treat five
separate drainage areas. The total percent imperviousness of the site is 78.8%. This
project is within 0.5 miles of SA waters and the use of infiltration devices was rejected by
Mr. Vincent Lewis on behalf of NC- DWQ. Due to the poor infiltrating conditions on the
site, sand filters are used to treat the design treatment volume. In order to meet pre -post
requirements, each basin discharges to a depressional area, usually a wetland, to
ensure that downstream receiving waters are not actually receiving discharge from the
sand filters during the design storm.
Stormwater Design Parameters
The sand filters are based on the following parameters or objectives:
• Provide 85% TSS removal
• Protect the value of the receiving water resource
• 3.7" rainfall for basin storage sizing
• The 1 yr rainfall discharge from the filter must infiltrate before reaching surface
waters
• Ratio of impervious surface to the total area of the drainage area
• Rainfall exceeding the design storm will bypass the basins and flow through a
minimum of 50' long vegetated filter
Discussion of Treatment Measures
The existing permitted treatment is to utilize five separate sand filters to meet the
TSS and Peak Flow requirements set forth by DWQ. Flow splitter devices are provided
to allow any runoff volume that exceeds the design storage volume to be routed and
bypass the sand filter treatments. The level spreader length is designed to handle the 10
yr peak runoff rate, so no bypass of the filter is necessary.
This modification is addressing the decrease in impervious area within drainage area 5,
the resulting calculation adjustments, and the adjusted routing of the bypass flow to the
designed stormwater level spreader. Specifically, to insure the changes are correctly
accounted for in the permit documents. The attached annotated plansheets depict the
updated impervious areas and site conditions.
Conclusion
This Stormwater Management Plan represents an environmentally sensitive and
effective plan for utilizing the proposed stormwater treatments to accommodate the
increased runoff of the proposed site development.

Project Description/General Information
This document is to serve as a modification to an existing permit (SW8 080907)
for the MCB Camp Lejeune — AAV project. The existing permit accounted for five sand
filters and associated level spreaders, flow splitters and filter strips. This modification is
the result of two changes to drainage area 5, outlined below:
1. The proposed impervious parking lot within drainage area 5 has been
reduced due to existing sanitary sewer lines which conflicted with the
proposed parking lot location. As a result, the original proposed impervious
area of 23,217 sf has been decreased to 15,694 sf (Attached Sheet C-3 and
C-4) within drainage area 5 however the proposed Sand Filter # 5 and its
associated level spreader were built as permitted under SW8080907.
2. It was determined that the bypass flow could not be routed to the intended
discharge location due to impacts to existing utilities and a oil/water separator
outlet. In accordance with SL2006-246, the bypass outlet will be re-routed to
the existing stormwater level spreader which is appropriately designed to
handle the bypass flows from the site.
At the time of this report, all of the site work has been completed except for the
re-routing of the bypass pipe to the level spreader.
The AAV Company Project is located off Courthouse Rd. on Camp Lejeune
Marine Corps Base in Onslow County, NC. Although no specific tract can be identified
with this project (the base in one large, contiguous property) the area being disturbed for
the project is approximately 6.92 acres. The project will be avoiding impacts of
wetlands.

Identify Project Involvement
This project is a part of the White Oak River Basin, and is currently not subject to
any buffer rules. The site is approximately 2,500 feet from the New River and
approximately 417 feet from Courthouse Bay, just outside of Sneads Ferry, NC and is
located in Onslow County, which is as of October 1, 2011 is subject to the Coastal
Stormwater Rules. However, the original permit for this project was covered by the
NPDES Phase II Stormwater Rules. The NCDWQ Stream Classification of Courthouse
Bay is SA, HQW and its NCDWQ Index Number is 19-36. The Stream Classification of
the New River is SA, HQW and its Index Number is 19-27.

The proposed project stormwater plan will meet the requirements of detaining the
3.7 inch rainfall event for a period of approximately 2 days, per the requirements by the
State as referenced from the DWQ Stormwater Manual, July 2007. The Stormwater
Design is Nigh Density, Coastal Stormwater. Five sand filters are proposed to treat five
separate drainage areas. The total percent imperviousness of the site is 78.8%. This
project is within 0.5 miles of SA waters and the use of infiltration devices was rejected by
Mr. Vincent Lewis on behalf of NC- DWQ. Due to the poor infiltrating conditions on the
site, sand filters are used to treat the design treatment volume. In order to meet pre -post
requirements, each basin discharges to a depressional area, usually a wetland, to
ensure that downstream receiving waters are not actually receiving discharge from the
sand filters during the design storm.
Stormwater Desiqn Parameters
The sand filters are based on the following parameters or objectives:
• Provide 85% TSS removal
• Protect the value of the receiving water resource
• 3.7" rainfall for basin storage sizing
• The 1 yr rainfall discharge from the filter must infiltrate before reaching surface
waters
• Ratio of impervious surface to the total area of the drainage area
• Rainfall exceeding the design storm will bypass the basins and flow through a
minimum of 50' long vegetated filter
Discussion of Treatment Measures
The existing permitted treatment is to utilize five separate sand filters to meet the
TSS and Peak Flow requirements set forth by DWQ. Flow splitter devices are provided
to allow any runoff volume that exceeds the design storage volume to be routed and
bypass the sand filter treatments. The level spreader length is designed to handle the 10
yr peak runoff rate, so no bypass of the filter is necessary.
This modification is addressing the decrease in impervious area within drainage area 5,
the resulting calculation adjustments, and the adjusted routing of the bypass flow to the
designed stormwater level spreader. Specifically, to insure the changes are correctly
accounted for in the permit documents. The attached annotated plansheets depict the
updated impervious areas and site conditions.
Conclusion
This Stormwater Management Plan represents an environmentally sensitive and
effective plan for utilizing the proposed stormwater treatments to accommodate the
increased runoff of the proposed site development.

IV. PROJECT INFORMATION
1. In the space provided below, briLfly summarize how the stormwater runoff will be treated.
The existing permit (SW8 080907) accounted for 23,217 sf of impervious area within drainage area_5 as well as
an outlet basin to treat bypass volume in order to not directly discharge into the bay. This "mod" is a result of
the decrease of impervious area within drainage area 5 from 23,217 sf to 15,694 sf, resulting adjustments to
calculations due to the decrease of BUA and the removal of the outlet basin due to the re-routing of the
bypass to the associated level spreader/vegetated filter strip on the Northeast side of the project site. The
will not change due to the decrease in BUA.
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 PUD Approval 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 11 -- Post Construction

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 drainage area will be carefully managed to reduce the sediment load to the
sand filter.
— Once a year, sand media will be skimmed.
— The sand filter media will be replaced whenever it fails to function properly after
vacuuming.
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.

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
(N1PC, 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 Iocation and will be

Dear Mr. Baker:
Natural Resources
Dee Freeman
Secretary
On November 7; 2011, the Division received an incomplete State Stormwater Management Application for the project
listed above. The application and check number 014178082. in the amount of $505 are being returned because the
application package lacked the necessary elements to accept it for review. Please provide the following information
upon the next submittal of this application package: -
This was originally permitted under the Phase II rule (SL2006-246) on 10008 with drainage area 95 (DA#5)
being 23,468sf with 23,217sf built -upon -area (BUA) in the DA. The permit was modified 417110 but there
were no changes to DA#5. This application shows that the sand filter effluent would drain to an Infiltration
basin per SL2006-246. I understand that this modification will reduce the DA#5 BUA to 15,694sf. But, there
will still be effluent from the sand filter that has to be addressed per SL2006-246. Please address this
requirement.
Please visit DWO's website at http:llh2o.enr.state.nc.us/su/bmp_forms.htm to download the latest available forms.
Please provide the requested information and return the package to the address below. Note that the 90-day
statutory permit review time begins upon receipt of a complete application. If you have any questions, please do not
hesitate to call me at [phone] or email me at [e-mail].
Sincerely,
C9

IV. PROJECT INFORMATION
r. In the space provided below, briefly summarize how the stormwater runoff will be treated.
The existing permit (SW8 080907) accounted for 23,217 sf of impervious area within drain-earea 5 as well as
an infiltration basin to treat bypass volume in order to not directly discharge into the bay. This "mod" is a
result of the decrease of impervious area within drainage area 5 from 23,217 sf to 15,694 sf, resulting
adjustments to calculations due to the decrease of BUA and the removal of the infiltration basin due to the re-
routing of the bypass to an existing stormwater drainage system on the Northeast side of the project site. The
sand filter size will not change due to the decrease in BUA.
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 PUD Approval 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: 28.1 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*:28.1 acres
Total project area shall be calculated to exclude the following the normal pool of im ounded structures, the area
between the banks of streams and rivers, the area below the Normal High Water (NM line or Mean High Water
(MHW) line, and coastal wetlands landward from the NHW (or MHW) line. The resultant project area is used to
calculate overall percent built upon area (1311A). Non -coastal wetlands landward of the NNW (or MH1M line may
be included in the total project area.
8. Project percent of impervious area. (Total Impervious Area J Total Project Area) X 100 = 78.8 %
9. How many drainage areas does the project have?5 (For high density, count 1 for each proposed engineered
stormwater BMP_ For Iow 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.

Andrew,
I briefly went through this application this morning and I have a few questions for you. It looks like this was originally
permitted under the Phase II rule (51-2006-246) on 10/8/08 with drainage area #5 being 23,468sf with 23,217sf BUA in
the DA. The permit was modified 4/7/10 but there were no changes to DA#5. These plans show that the sand filter
effluent would drain to an infiltration basin per SL2006-246 (see attached andrewb.wilson@aecompage 16, h(3)). I
understand that this modification will reduce the DA#5 BUR to 15,694sf. But, there will still be effluent from the sand
filter that has to be addressed per 51-2006-246. How will that be accomplished by this design?
Thanks,
Kelly

PROJECT DESCRIPTION/GENERAL INFORMATION
THIS DOCUMENT IS TO SERVE AS A MODIFICATION TO AN EXISTING PERMIT
(SW8 080907) FOR THE MCB CAMP LEJEUNE - AAV PROJECT. THE EXISTING
PERMIT ACCOUNTED FOR FIVE SAND FILTERS AND ASSOCIATED LEVEL SPREADERS,
FLOW SPLITTERS AND FILTER STRIPS. THIS MODIFICATION IS THE RESULT OF TWO
CHANGES TO DRAINAGE AREA 5, OUTLINED BELOW:
1. THE PROPOSED IMPERVIOUS PARKING LOT WITHIN DRAINAGE AREA 5 HAS
BEEN REDUCED DUE TO EXISTING SANITARY SEWER LINES WHICH
CONFLICTED WITH THE PROPOSED PARKING LOT LOCATION. AS A RESULT,
THE ORIGINAL PROPOSED IMPERVIOUS AREA OF 23,217 SF HAS BEEN
DECREASED TO 15,694 SF (ATTACHED SHEET C-3 AND C-4) WITHIN
DRAINAGE AREA 5 HOWEVER THE PROPOSED SAND FILTER # 5 AND ITS
ASSOCIATED LEVEL SPREADER WERE BUILT AS PERMITTED UNDER
S W8080907 .
2. IT WAS DETERMINED THAT THE BYPASS FLOW COULD NOT BE ROUTED TO
THE INTENDED DISCHARGE LOCATION DUE TO IMPACTS TO EXISTING
UTILITIES AND A OIL/WATER SEPARATOR OUTLET. THE BYPASS OUTLET HAS
BEEN MOVED TO THE EXISTING STORMWATER INFRASTRUCTURE THAT WAS
ALREADY RECEIVING ALL FLOW FROM THE SITE.
AT THE TIME OF THIS REPORT, ALL OF THE SITE WORK HAS BEEN COMPLETED.
THE AAV COMPANY PROJECT IS LOCATED OFF COURTHOUSE RD. ON CAMP
LEJEUNE MARINE CORPS BASE IN ONSLOW COUNTY, NC. ALTHOUGH NO SPECIFIC
TRACT CAN BE IDENTIFIED WITH THIS PROJECT (THE BASE IN ONE LARGE, CONTIGUOUS
PROPERTY) THE AREA BEING DISTURBED FOR THE PROJECT IS APPROXIMATELY 6.92
ACRES. THE PROJECT WILL BE AVOIDING IMPACTS OF WETLANDS.

IDENTIFY PROJECT INVOLVEMENT
THIS PROJECT IS A PART OF THE WHITE OAK RIVER BASIN, AND IS CURRENTLY
NOT SUBJECT TO ANY BUFFER RULES. THE SITE IS APPROXIMATELY 2,500 FEET FROM
THE NEW RIVER AND APPROXIMATELY 417 FEET FROM COURTHOUSE BAY, JUST
OUTSIDE OF SNEADS FERRY, NC AND IS LOCATED IN ONSLOW COUNTY, WHICH IS AS
OF OCTOBER 1, 201 1 IS SUBJECT TO THE COASTAL STORMWATER RULES. HOWEVER,
THE ORIGINAL PERMIT FOR THIS PROJECT WAS COVERED BY THE NPDES PHASE it
STORMWATER RULES. THE NCDWQ STREAM CLASSIFICATION OF COURTHOUSE BAY
IS SA, HOW AND ITS NCDWQ INDEX NUMBER IS 19-36. THE STREAM
CLASSIFICATION OF THE NEW RIVER IS SA, HQW AND ITS INDEX NUMBER IS 19-27,
THE PROPOSED PROJECT STORMWATER PLAN WILL MEET THE REQUIREMENTS
OF DETAINING THE 3.7 INCH RAINFALL EVENT FOR A PERIOD OF APPROXIMATELY 2

DAYS, PER THE REQUIREMENTS BY THE STATE AS REFERENCED FROM THE DWQ
STORMWATER MANUAL, JULY 2007. THE STORMWATER DESIGN IS HIGH DENSITY,
COASTAL STORMWATER. FIVE SAND FILTERS ARE PROPOSED TO TREAT FIVE SEPARATE
DRAINAGE AREAS. THE TOTAL PERCENT IMPERVIOUSNESS OF THE SITE IS 78.8%,
THIS PROJECT IS WITHIN 0.5 MILES OF SA WATERS AND THE USE OF INFILTRATION
DEVICES WAS REJECTED BY MR. VINCENT LEWIS ON BEHALF OF NC- DWQ. DUE TO
THE POOR INFILTRATING CONDITIONS ON THE SITE, SAND FILTERS ARE USED TO TREAT
THE DESIGN TREATMENT VOLUME. IN ORDER TO MEET PRE -POST REQUIREMENTS,
EACH BASIN DISCHARGES TO A DEPRESSIONAL AREA, USUALLY A WETLAND, TO
ENSURE THAT DOWNSTREAM RECEIVING WATERS ARE NOT ACTUALLY RECEIVING
DISCHARGE FROM THE SAND FILTERS DURING THE DESIGN STORM.
STORMWATER DESIGN PARAMETERS
THE SAND FILTERS ARE BASED ON THE FOLLOWING PARAMETERS OR
OBJECTIVES:
• PROVIDE 85% TSS REMOVAL
• PROTECT THE VALUE OF THE RECEIVING WATER RESOURCE
• 3.7" RAINFALL FOR BASIN STORAGE SIZING
• THE 1 YR RAINFALL DISCHARGE FROM THE FILTER MUST INFILTRATE BEFORE
REACHING SURFACE WATERS
• RATIO OF IMPERVIOUS SURFACE TO THE TOTAL AREA OF THE DRAINAGE AREA
• RAINFALL EXCEEDING THE DESIGN STORM WILL BYPASS THE BASINS AND FLOW
THROUGH A MINIMUM OF 50' LONG VEGETATED FILTER
DISCUSSION OF TREATMENT MEASURES
THE EXISTING PERMITTED TREATMENT IS TO UTILIZE FIVE SEPARATE SAND
FILTERS TO MEET THE TSS AND PEAK FLOW REQUIREMENTS SET FORTH BY DWQ.
FLOW SPLITTER ❑EVICES ARE PROVIDED TO ALLOW ANY RUNOFF VOLUME THAT
EXCEEDS THE ❑ESIGN STORAGE VOLUME TO BE ROUTED AND BYPASS THE SAND FILTER
TREATMENTS. THE LEVEL SPREADER LENGTH IS DESIGNED TO HANDLE THE 10 YR
PEAK RUNOFF RATE, SO NO BYPASS OF THE FILTER IS NECESSARY.
THIS MODIFICATION IS ADDRESSING THE DECREASE IN IMPERVIOUS AREA WITHIN
DRAINAGE AREA 5, THE RESULTING CALCULATION ADJUSTMENTS, THE ADJUSTED
ROUTING OF THE BYPASS FLOW TO THE EXISTING STORMWATER INFRASTRUCTURE.
SPECIFICALLY, TO INSURE THE CHANGES ARE CORRECTLY ACCOUNTED FOR IN THE
PERMIT DOCUMENTS, THE ATTACHED ANNOTATED PLANSHEETS DEPICT THE UPDATED
IMPERVIOUS AREAS AN❑ SITE CONDITIONS.
CONCLUSION
THIS STORMWATER MANAGEMENT PLAN REPRESENTS AN ENVIRONMENTALLY
SENSITIVE AND EFFECTIVE PLAN FOR UTILIZING THE PROPOSED STORMWATER
TREATMENTS TO ACCOMMODATE THE INCREASED RUNOFF OF THE PROPOSE❑ SITE
❑EVELOPMENT.

IV. PROJECT INFORMATION
1. In the space provided below, briefly summarize how the stormwater runoff will be treated.
The existing permit 080907) accounted for 23,217 sf of impervious area within drainage area 5 as well as
an infiltration basin to treat bypass volume in order to not directly discharge into the bay. This "mod" is a
result of the decrease of impervious area within drainage area 5 from 23,217 sf to 15,694 sf, resulting
adiustments to calculations due to the decrease of BUA and the removal of the infiltration basin due to the re-
routing of the bypass to an existing stormwater drainage system on the Northeast side of the project site. The
sand filter size will not change due to the decrease in BUA.^
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 PUD Approval 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 ti - Post Construction
3. Stormwater runoff from this project drains to the White Oak River basin.
4. Total Property Area: 28.1 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+:28.1 acres
+ Total project area shall be calculated to exclude thefollowing: the normal pool of impounded structures, the area
between the batiks of streams and rivers, the area below the Normal Hi 11 Water (NkM line or Mean High Water
(MHM line, and coastal wetlands landward from the NHW (or M;A line. The resultant project area is used to
calculate overall percent built upon area (BUA). Non -coastal wetlands landward of the 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 = 78.8 %
9. How many drainage areas does the project have?5 (For high density, count I for each proposed engineered
stormwater BMP. For low density and other projects, use I 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

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 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:
— The drainage area will be carefully managed to reduce the sediment load to the
sand filter.
— Once a year, sand media will be skimmed.
— The sand filter media will be replaced whenever it fails to function properly after
vacuuming.
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.
