D. Impact Justification and Mitigation
1.Avoidance and Minimization
1a.Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The applicant has designed the proposed residential sub-division to avoid other impact to streams and wetlands, specifically
associated with lot/pad fill. The applicant has further demonstrated avoidance and minimization of stream impacts by
proposing to construct culvert head/end walls. The applicant has designed the stream crossing in a relatively straight portion
of the stream that does not contain adjacent wetlands.Shifting the crossing up-gradient would impact wetlands. Shifting the
crodssing down-gradient would impact more perennial stream.The remaining 6,069 linear feet of stream and 1.56 acres of
wetlands are being avoided.
1b.Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
The clearing limits will be staked and silt fence will be used. A temporary coffer dam will be installed upgradient of the
proposed culvert. During construction, water will be pumped around the construction f ootprint. Appropriate stream bank
protection will be provided in the channel during construction and all excess excavated material will be immediately removed
from the stream bank crossing area.The rip rap is being keyed in to further minimize the impact s to the stream.Upon
completion of the culvert installation, the temporary sand bag coffer dam will be removed and flow will be diverted through t he
culvert. Following construction, disturbed banks will be restored to similar pre -construction conditions,matted and seeded/live
staked.

5.Endangered Species and Designated Critical Habitat (Corps Requirement)
5a.Will this project occur in or near an area with federally protected species or
habitat?Yes No
5b.Have you checked with the USFWS concerning Endangered Species Act
impacts?Yes No
5c.If yes, indicate the USFWS Field Office you have contacted.Raleigh
Asheville
5d.What data sources did you use to determine whether your site would impact Endangered Species or Designated Critical
Habitat?
We consulted the USFWS Website to determine if federally protected endangered or threatened species inhabit Guilford
County, NC.The bald eagle, Cape Fear shiner, Roanoke logperch, Schweinitz's sunflower and small whorled pogonia are
listed as federally protected species. Based on our observations, the proposed dev elopment will not disturb the bald
eagle. The site is not located within the current ranges for the Cape Fear shiner and Roanoke logperch based on a
review of the USFWS Environmental Conservation Online System. Suitable habitat for Schweinitz's sunflower and small
whorled pogonia is not located on the site. Therefore,it is our opinion that the proposed project will have no effect on
federally protected species or their habitat.

We reviewed the SHPO Map (http://gis.ncdcr.gov/hpoweb/)to identify historic and/or archaeological resources on the
site. The map does not identify eligible for listing properties on the site. Several nearby properties are mapped. The Oak
Ridge Local Historic District is located 100 feet and more west and northwest of the site. Several surveyed only
properties are located 400 feet and more north of the site. The Oak Ridge Military Academy Historic District is located
600 feet and more west of the site. The Oakhurst House, a Nationally Registered structure is located approximately 750
feet west of the site.A copy of the map is included as an attachment.

thirty days after completion.
CONDITIONS WHERE PRAGTIGE APPLIES
Where bare soil has been exposed by grading, and vegetatiive cover is needed for one year or less.
May include Such areas as temporary sediment pond, diversions, soil stockpiles, building pads, rough -graded
road banks, etc. It is also used to provide a temporary perimeter buffer.
PREPARATION
Prepare Seedbed by ripping, chiseling, harrowing, or plowing to depth of at least six inches so as to produce
a loose friable surface. Incorporate 750-1,000 pounds 10-10-10 fertilizer and up to two tons of dolomitic
lime per acre. (Note: Lime may not be needed if a soil test indicates a ph of 6.5 or higher). Mulching is
required according to the same specifications as for permanent seeding unless waived by Soil Scientist.

4. compact the ridge to prevent unequal settlement and to provide stability
against seepage.
5. Vegetatively stabilize the diversion after Its Installation.
Maintenance Inspect permanent diversions after every rainfall during the construction opera-
tion. Immediately remove any obstructions from the flow area and repair the
diversion ridge. check outlets and make timely repairs as needed. Maintain the
vegetation In a vigorous, healthy condition at all times.
PERMANENT DIVERSIONS
Construction I. Remove and properly dispose of all trees, brush, stumps, or other ob)ec-
5peciflCations tionable material.
2. Ensure that the minimum constructed cross section meets all design requirements
3. Ensure that the top of the dike is not lower at any point than the design
elevation plus the specified settlement.
4. Provide sufficient room around diversions to permit machine regrading and cleanout.
5. Vegetate the ridge immediately after construction, unless it will remain in place less
than 30 working days.
Maintenance Inspect temporary diversions once a week and after every rainfall. Immediately remove
�i sediment from the flow area and repair the diversion ridge. Carefully check outlets and
11 make timely repairs as needed. Hhen the area protected is permanently stabilized,
remove the ridge and the channel to blend with the natural ground level and appropriately
D stabilize it.

CONSTRUCTION SPECIFICATIONS
1. CLEAR, GRUB AND STRIP THE AREA UNDER THE EMBANKMENT OF ALL VEGETATION AND
ROOT MAT. REMOVE ALL SURFACE SOIL CONTAINING HIGH AMOUNTS OF ORGANIC MATTER
AND STOCKPILE OR DISPOSE OF IT PROPERLY. HAUL ALL OBJECTIONABLE MATERIAL TO THE
DESIGNATED DISPOSAL AREA. PLACE TEMPORARY SEDIMENT CONTROL MEASURES BELOW
BASIN AS NEEDED.
2. ENSURE THAT FILL MATERIAL FOR THE EMBANKMENT IS FREE OF ROOTS, WOODY
VEGETATION. ORGANIC MATTER AND OTHER OBJECTIONABLE MATERIAL. PLACE THE FILL IN
LIFTS NOT TO EXCEED 9 INCHES, AND MACHINE COMPACT IT. OVER FILL THE EMBANKMENT
6 INCHES TO ALLOW FOR SETTLEMENT.
3. SHAPE THE BASIN TO THE SPECIFIED DIMENSIONS. PREVENT THE SKIMMING DEVICE FROM
SETTLING INTO THE MUD BY EXCAVATING A SHALLOW PIT UNDER THE SKIMMER OR
PROVIDING LOW SUPPORT UNDER THE SKIMMER OF STONE OR TIMBER.
4. PLACE THE BARREL (TYPICALLY 4-INCH SCHEDULE 40 PVC PIPE) ON A FIRM, SMOOTH
FOUNDATION OF IMPERVIOUS SOIL. DO NOT USE PERVIOUS MATERIAL SUCH AS SAND,
GRAVEL OR CRUSHED STONE AS BACKFILL AROUND THE PIPE. PLACE THE FILL MATERIAL
AROUND THE PIPE SPILLWAY IN 4-INCH LAYERS AND COMPACT IT UNDER AND AROUND THE
PIPE TO AT LEAST THE SAME DENSITY AS THE ADJACENT EMBANKMENT. CARE MUST BE
TAKEN NOT TO RAISE THE PIPE FROM THE FIRM CONTACT WITH ITS FOUNDATION WHEN
COMPACTING UNDER THE PIPE HAUNCHES.
PLACE A MINIMUM DEPTH OF 2 FEET OF COMPACTED BACKFILL OVER THE PIPE SPILLWAY
BEFORE CROSSING IT WITH CONSTRUCTION EQUIMENT. IN NO CASE SHOULD THE PIPE
CONDUIT BE INSTALLED BY CUTTING A TRENCH TROUGH THE DAM AFTER THE EMBANKMENT
IS COMPLETE.
5. ASSEMBLE THE SKIMMER FOLLOWING THE MANUFACTURERS INSTRUCTIONS. OR AS DESIGNED.
6. LAY THE ASSEMBLED SKIMMER ON THE BOTTOM OF THE BASIN WITH THE FLEXIBLE JOINT AT
THE INLET OF THE BAREL PIPE. ATTACH THE FLEXIBLE JOINT TO THE BARREL PIPE AND
POSITION THE SKIMMER OVER THE EXCAVATED PIT OR SUPPORT. BE SURE TO ATTACH TA
ROPE TO THE SKIMMER AND ANCHOR IT TO THE SIDE OF THE BASIN. THIS WILL BE USED
TO PULL THE SKIMMER TO THE SIDE FOR MAINTENANCE.
7. EARTHEN SPILLWAYS - INSTALL THE SPILLWAY IN UNDISTURBED SOIL TO THE GREATEST
EXTENT POSSIBLE. THE ACHIEVEMENT OF PLANNED ELEVATIONS, GRADE, DESIGN WIDTH, AND
ENTRANCE AND EXIT CHANNEL SLOPES ARE CRITICAL TO THE SUCCESSFUL OPERATION OF
THE SPILLWAY. THE SPILLWAY SHOULD BE LINED WITH LAMINATED PLASTIC OR (IMPERMEABLE
GEOTEXTILE FABRIC. THE FABRIC MUST BE WIDE ANE LONG ENOUGH TO COVER THE BOTTOM
AND SIDES AND EXTEND ONTO THE TOP OF THE DAM FOR ANCHORING IN A TRENCH. THE
EDGES MAY BE SECURED WITH 8-INCH STAPLES OR PINS. THE FABRIC MUST BE LONG
ENOUGH TO EXTEND DOWN THE SLOPE AND EXIT ONTO STABLE GROUND. THE WIDTH OF
THE FABRIC MUST BE ONE PIECE, NOT JOINED OR SPLICED; OTHERWISE WATER CAN GET
UNDER THE FABRIC. IF THE LENGTH OF THE FABRIC IS INSUFFICIENT FOR THE ENTIRE
LENGTH OF THE SPILLWAY, MULTIPLE SECTIONS, SPANNING THE COMPLETE WIDTH, MAY BE
USED. THE UPPER SECTIONS) SHOULD OVERLAP THE LOWER SECTIONS) SO THAT WATER
CANNOT FLOW UNDER THE FABRIC. SECURE THE UPPER EDGE AND SIDES OF THE FABRIC IN
A TRENCH WITH STAPLES OR PINS. (ADAPTED FROM "A MANUAL FOR DESIGNING, INSTALLING
AND MAINTAINING SKIMMER SEDIMENT BASINS." FEBRUARY, 1999, J.W. FAIRCLOTH AND SON.)
8. INLETS - DISCHARGE WATER INTO THE BASIN IN A MANNER TO PREVENT EROSION. USE
TEMPORARY SLOPE DRAINS OR DIVERSIONS WITH OUTLET PROTECTION TO DIVERT SEDIMENT
LADEN WATER TO THE UPPER END OF THE POOL AREA TO IMPOVED BASIN TRAP
EFFICIENCY (REFERENCES: RUNOFF CONTROL MESURES AND OUTLET PROTECTION).
9. EROSION CONTROL - CONSTRUCT THE STRUCTURE SO THAT THE DISTURBED AREA IS
MINIMIZED. DIVERT SURFACE WATER AWAY FROM BARE AREAS. COMPLETE THE EMBANKMENT
BEFORE THE AREA IS CLEARED. STABILIZE THE EMERGENCY SPILLWAY EMBANKMENT AND
ALL OTHER DISTURBED AREAS ABOVE THE CREST OF THE PRINCIPAL SPILLWAY IMMEDIATELY
AFTER CONSTRUCTION (REFERENCES: SURFACE STABILZATION).
10. INSTALL POROUS BAFFLES AS SPECIFIED IN PRACTICE 6.65, POROUS BAFFLES.
11. AFTER ALL THE SEDIMENT -PRODUCING AREAS HAVE BEEN PERMANENTLY STABILIZED,
REMOVE THE STRUCTURE AND ALL THE UNSTABLE SEDIMENT. SMOOTH THE AREA TO BLEND
WITH THE ADJOINING AREAS AND STABILIZE PROPERLY. (REFERENCES: SURFACE
STABILIZATION).
MAINTENANCE
INSPECT SKIMMER SEDIMENT BASINS AT LEAST WEEKLY AND AFTER EACH SIGNIFICANT
(ONE-HALF INCH OR GREATER) RAINFALL EVENT AND REPAIR IMMEDIATELY. REMOVE SEDIMENT
AND RESTORE THE BASIN TO ITS ORIGINAL DIMENSIONS WHEN SEDIMENT ACCUMULATES TO
ONE-HALF THE HEIGHT OF THE FIRST BAFFLE. PULL THE SKIMMER TO ONE SIDE SO THAT THE
SEDIMENT UNDERNEATH IT CAN BE EXCAVATED. EXCAVATE THE SEDIMENT FROM THE ENTIRE
BASIN, NOT JUST AROUND THE SKIMMER OR THE FIRST CELL. MAKE SURE VEGETATION
GROUWING IN THE BOTTOM IF THE BASIN DOES NOT HOLD DOWN THE SKIMMER.
REPAIR THE BAFFLES IF THEY ARE DAMAGED. RE -ANCHOR THE BAFFLES IF WATER IS FLOWING
UNDERNEATH OR AROUND THEM.
IF THE SKIMMER IS CLOGGED WITH TRASH SND THERE IS WATER IN THE BASIN, USUALLY
JERKING ON THE ROPE WILL MAKE THE SKIMMER BOB UP AND DOWN AND DISLODGE THE DERIS
AND RESORE FLOW. IF THIS DOES NOT WORK PULL THE SKIMMER OVER TO THE SIDE OF THE
BASIN AND REMOVE THE DERRIS. ALSO CHECK THE ORIFICE INSIDE THE SKIMMER TO SEE IF IT
ISCLOGGED; IF SO REMOVE THE DEBRIS.
IF THE SKIMMER ARM OR BARREL PIPE IS CLOGGED, THE ORIFICE CAN BE REMOVED AND THE
OBSTURCION CLEARED WITH A PLUMBER'S SNAKE OR BY FLUSHING WITH WATER. BE SURE AND
REPLACE THE ORIFICE BEFORE REPOSITIONING THE SKIMMER.
CHECK THE FABRIC LINED SPILLWAY FOR DAMAGE AND MAKE ANY REQUIRED REPAIRS WITH
FABRIC THAT SPANS THE FULL WIDTH OF THE SPILLWAY. CHECK THE EMBANKMENT, SPILLWAYS,
AND OUTLET FOR EROSION DAMAGE, AND INSPECT THE EMBANKMENT FOR PIPING AND
SETTLEMENT. MAKE ALL NECESSARY REPAIRS IMMEDIATELY. REMOVE ALL TRASH AND OTHER
DEBRIS FROM THE SKIMMER AND POOL AREAS.
FREEZING WEATHER CAN RESULT IN ICE FORMING IN THE BASIN. SOME SPECIAL PRECAUTIONS
SHOULD BE
TAKEN IN THE WINTER TO PREVENT THE SKIMMER FROM PLUGGING WITH ICE.

CONSTRUCTION
1. GRADE THE BASIN SO THAT THE BOTTOM IS LEVEL FRONT TO BACK AND SIDE TO SIDE.
2. INSTALL THE COIR FIBER BAFFLES IMMEDIATELY UPON EXCAVATION OF THE BASINS.
3. INSTALL POSTS ACROSS THE WIDTH OF THE SEDIMENT TRAP (PRACTICE 6.62, SEDIMENT FENCE).
4. STEEL POSTS SHOULD BE DRIVEN TO A DEPTH OF 24 INCHES AND SPACED A MAXIMUM OF 4 FEET APART. THE TOP OF THE FABRIC
SHOULD BE A MINIMUM OF 6 INCHES HIGHER THAN THE INVERT OF THE SPILLWAY. TOPS OF BAFFLES SHOULD B A MINIMUM OF 2 INCHES
LOWER THAN THE TOP OF THE EARTHEN EMBANKMENT.
5. INSTALL AT LEAST THREE ROWS OF BAFFLES BETWEEN THE INLET AND OUTLET DISCHARGE POINT. BASINS LESS THAN 20 FEET IN LENGTH
MAY USE 2 BAFFLES.
6. ATTACH A 9 GAUGE HIGH TENSION WIRE STRAND TO THE STEEL POSTS AT A HEIGHT OF 6 INCHES ABOVE THE SPILLWAY ELEVATION
WITH PLASTIC TIES OR WIRE FASTENERS TO PREVENT SAGGING. IF THE TEMPROARY SEDIMENT BASIN WILL BE CONVERTED TO A
PERMANENT STORMWATER BASIN OF A GREATER DEPTH, THE BAFFLE HEIGHT SHOULD BE BASED ON THE POOL DEPTH DURING USE AS
A TEMPORARY SEDIMENT BASIN.
7. EXTEND 9 GAUGE MINIMUM HIGH TENSION WIRE STRAND TO SIDE OF BASIN OR INSTALL STEEL T-POSTS TO ANCHOR BAFFLE TO SIDE OF
BASIN AND SECURE TO VERTICAL END POSTS AS SHOWN IN FIGURE 6.65b.
8. DRAPE THE COIR FIBER MAT OVER THE WIRE STRAND MOUNTED AT A HEIGHT OF 6 INCHES ABOVE THE SPILLWAY ELEVATION. SECURE THE
COIR FIBER MAT TO THE WIRE STRAND WITH PLASTIC TIES OR WIRE FASTENERS. ANCHOR THE MATTING TO THE SIDES AND FLOOR OF
THE BASIN WITH 12 INCH WIRE STAPLES, APPROXIMATELY 1 FOOT APART, ALONG THE BOTTOM AND SIDE SLOPES OF THE BASIN.
9. DO NOT SPLICE THE FABRIC, BUT USE A CONTINUOUS PIECE ACROSS THE BASIN.
10. ADJUSTMENTS MAY BE REQUIRED IN THE STAPLING REUQIREMENTS TO FIT INDIVIDUAL SITE CONDITIONS.
MAINTENANCE
INSPECT BAFFLES AT LEAST ONCE A WEEK AND AFTER EACH RAINFALL. MAKE ANY REQUIRED REPAIRS IMMEDIATELY.
BE SURE TO MAINTAIN ACCESS TO THE BAFFLES. SHOULD THE FABRIC OF A BAFFLE COLLAPSE, TEAR, DECOMPOSE, OR BECOME INEFFECTIVE,
REPLACE IT PROMPTLY.
REMOVE SEDIMENT DEPOSITS WHIN IT REACHES HALF FULL, TO PROVIDE ADEQUATE STORAGE VOLUME FOR THE NEXT RAIN AND TO REDUCE
PRESURE ON THE BAFFLES. TAKE CARE TO AVOID DAMAGING THE BAFFLES DURING CLEANOUT AND REPLACE IF DAMAGED DURING CLEANOUT
OPERATIONS. SEDIMENT DEPTH SHOULD NEVER EXCEED HALF TO DESIGNED STORAGE DEPTH.
AFTER THE CONTRUBUTING DRAINAGE AREA HAS BEEN PROPERLY STABILIZED, REMOVE ALL BAFFLE MATERIALS AND UNSTABLE SEDIMENT
DEPOSIT, BRING THE AREA TO GRADE, AND STABILIZE IT.

Notes
I. La is the length of the riprap
apron.
2. d=1.5 times the maximum stone
diameter but not less than 6".
3. In a well-defined channel ex-
tend the apron up the channel
banks to an elevation of 6"
above the maximum tall water
depth or to the top of the bank,
whichever is less.
4. A filter blanket or filter fabric
should be installed between
the riprap and soil foundation.
CONSTRUCTION SPECIFICATIONS
I. Ensure that the subgrade for the filter and riprap follows the required lines
and grades shown in the plan. Compact and fill required In the subgrade to the
density of the surrounding undisturbed material. Low areas in the subgrade on
undisturbed soil may also be filled by increasing the riprap thickness.
2. The ripraand gravel filter must conform to the specified grading limits
p
shown on the plans.
3. Filter cloth, when used, must meet design requirements and be properly
protected from punching or tearing during installation. Repair any damage by
removing the riprap and placing another piece of filter cloth over the damaged
area. All connecting joints should overlap a minimum of I ft. If the damage is
extensive, replace the entire filter cloth.
4. Riprap may be placed by equipment, but take care to avoid damaging the filter.
5. The minimum thickness of the riprap should be 1.5 times the maximum stone
diameter.
6. Riprap may be field stone or rough quarry stone. It should be hard, angular,
highly weather -resistant and well graded.
-7. Construct the apron on zero grade with no overfoll at the end. Make the top
of the riprap at the downstream end level with the receiving area or slightly
below it.
8. Ensure that the apron is properly aligned with the receiving stream and
preferably straight throughout Its length. If a curve is needed to fit site
conditions, place It in the upper section of the apron.
cl. Immediately after construction,stobillze all disturbed areas with vegetation
(Practices 6.10, Temporary 5eed/ny, and (9.11, Permanent _15weed/nq ).
MAINTENANCE
Inspect riprap outlet structures after heavy rains to see if any erosion around or
below the riprap has taken place or if stones have been dislodged. Immediately
make all needed repairs to prevent further damage.

Gon5truction Sbecificotions
I. Glear the entrance and exit area of all vegetation, roots, and other objectionable
material and properly grade it.
2. Place the gravel to the specific grade and dimensions shown on the plans, and
smooth it.
3. Provide drainage to carry water to a sediment trap or other suitable outlet.
4. Use geotextile fabrics because they improve stability of the foundation In locations
subject to seepage or high water table.
Maintenance
Maintain the gravel pad in a condition to prevent mud or sediment from leaving the
construction site. This may require periodic topdressing with 2-inch stone. After each
rainfall, inspect and structure used to trap sediment and clean it out as necessary.
Immediately remove all objectionable materials spilled, washed, or tracked onto public
roadways.

In channels, roll out strips of netting parallel to
direction of flow and over the protective mulch.
Anchor netting in

INSTALLATION OF NETTING AND MATTING
Products designed to control erosion should be installed in accordance with
manufacturer's instructions. Any mat or blanket -type product used as a protective
mulch should provide cover of at least 30% of of the surface where it is applied.
Installation is Illustrated in Figure 6.14a.
I. Apply lime, fertilizer and seed before laying net or mat. If open -weave
netting is used, lime may be incorporated before Installing the net and fertilizer
and seed sprayed afterward.
2. Start laying the net from the top of the channel or slope and unroll it down
the grade. Allow netting to lay loosely on the soil but without wrinkles - do not
stretch.
3. To secure the net, bury the upslope end in a slot or trench no less than 6-inches
deep, cover with soil, and tamp firmly as shown in Figure 6.14a. Staple the net every
12 inches across the top end and every 3 ft around the edgges and bottom. Where
2 strips of net are laid side by side, the adjacent edges should be overlapped
3 Inches and stapled together. Each strip of netting should also be stapled down
the center, every 3 ft. Do not stretch the net when applying staples.
4. To join two strips, cut a trench to anchor the end of the new net. Overlap the
end of the previous roll 12 Inches, as shown In Figure 6.14a, and staple every 12 Inches
just below the anchor slot.
MAINTENANCE
Inspect all mulches periodically, and after rainstorms to check for rill erosion,
dislocation, or failure. Where erosion is observed, apply additional mulch. If
washout occurs, repair the slope grade, reseed, and reinstall mulch. Continue -
inspections until vegetation is firmly established.

$5000 PER DAY CIVIL PENALTY. THE INSTIGATION OF THIS CIVIL PENALTY REQUIRES NO
PRIOR NOTICE.
5. IN AN EFFORT TO MINIMIZE EROSION AND EXPOSURE TIME, EASEMENT AREAS SHALL NOT
BE GRUBBED OR GRADED UNTIL UTILITIES ARE READY TO BE INSTALLED. ALSO, THE IMMEDIATE
SEEDING OF DISTURBED EASEMENT AREAS AFTER UTILITIES ARE INSTALLED WILL ALSO
ELIMINATE MANY PROBLEMS. EASEMENT AREAS WHICH CROSS OR ARE ADJACENT TO
WATERCOURSES SHOULD RECEIVE SPECIAL CONSIDERATION.
6. NO LAND DISTURBING ACTIVITY SHALL BE PERMITTED IN PROXIMITY TO A LAKE OR
NATURAL WATERCOURSE UNLESS A BUFFER ZONE IS PROVIDED ALONG THE MARGIN
OF THE WATER BODY OF SUFFICIENT WIDTH TO CONFINE VISIBLE SILTATION WITHIN
THE 25% OF THE BUFFER ZONE NEAREST THE LAND DISTURBING ACTIVITY.
7. SIDE DITCHES 2% OR STEEPER SHALL BE RIP -RAPPED; OR SEEDED AND STABILIZED
WITH EXCELSIOR MATTING (OR OTHER APPROVED MATERIAL); OR STABILIZED BY ANY
OTHER METHOD APPROVED BY THE COUNTY SOIL EROSION CONTROL INSPECTOR.
8. IF A PERMANENT POND IS USED AS A SEDIMENT CONTROL DEVICE, OR DESIGNATED AS A
PERMANENT WATER QUALITY POND, IT MUST BE CLEANED OF SEDIMENT WHEN HALF FULL.
IT MUST ALSO BE CLEANED OUT TO DESIGN VOLUME; ENGINEERING CERTIFICATION OF
COMPLETION SUBMITTED, AND FINAL INSPECTION PERFORMED BY COUNTY STAFF BEFORE
THE GRADING PERMIT IS FINALIZED.
9. CONSTRUCTION ACTIVITIES DISTURBING ONE OR MORE ACRES WILL BE ISSUED A NPDES

1) The Corps of Engineers believes that there may be jurisdictional aquatic resources in the
review area, and the requestor of this PJD is hereby advised of his or her option to request
and obtain an approved JD (AJD) for that review area based on an informed decision after
having discussed the various types of JDs and their characteristics and circumstances when
they may be appropriate.

2) In any circumstance where a permit applicant obtains an individual permit, or a Nationwide
General Permit (NWP) or other general permit verification requiring "pre- construction
notification" (PCN), or requests verification for a non-reporting NWP or other general permit,
and the permit applicant has not requested an AJD for the activity, the permit applicant is
hereby made aware that: (1) the permit applicant has elected to seek a permit authorization
based on a PJD, which does not make an official determination of jurisdictional aquatic
resources; (2) the applicant has the option to request an AJD before accepting the terms and
conditions of the permit authorization, and that basing a permit authorization on an AJD could
possibly result in less compensatory mitigation being required or different special conditions;
(3) the applicant has the right to request an individual permit rather than accepting the terms
and conditions of the NWP or other general permit authorization; (4) the applicant can accept
a permit authorization and thereby agree to comply with all the terms and conditions of that
permit, including whatever mitigation requirements the Corps has determined to be necessary;
(5) undertaking any activity in reliance upon the subject permit authorization without
requesting an AJD constitutes the applicant's acceptance of the use of the PJD; (6) accepting a
permit authorization (e.g., signing a proffered individual permit) or undertaking any activity in
reliance on any form of Corps permit authorization based on a PJD constitutes agreement that
all aquatic resources in the review area affected in any way by that activity will be treated as
jurisdictional, and waives any challenge to such jurisdiction in any administrative or judicial
compliance or enforcement action, or in any administrative appeal or in any Federal court;
and (7) whether the applicant elects to use either an AJD or a PJD, the JD will be processed
as soon as practicable. Further, an AJD, a proffered individual permit (and all terms and
conditions contained therein), or individual permit denial can be administratively appealed
pursuant to 33 C.F.R. Part 331. If, during an administrative appeal, it becomes appropriate to
make an official determination whether geographic jurisdiction exists over aquatic resources
in the review area, or to provide an official delineation of jurisdictional aquatic resources in
the review area, the Corps will provide an AJD to accomplish that result, as soon as is
practicable. This PJD finds that there "may be" waters of the U.S. and/or that there "may be"
navigable waters of the U.S. on the subject review area, and identifies all aquatic features in
the review area that could be affected by the proposed activity, based on the following
information:

Jurisdictional Determination Request
Version: May 2017 Page 4

F. JURISDICTIONAL DETERMINATION (JD) TYPE (Select One)

I am requesting that the Corps provide a preliminary JD for the property identified herein.

A Preliminary Jurisdictional Determination (PJD) provides an indication that there may
be “waters of the United States” or “navigable waters of the United States”on a property.
PJDs are sufficient as the basis for permit decisions. For the purposes of permitting, all
waters and wetlands on the property will be treated as if they are jurisdictional “waters of
the United States”. PJDs cannot be appealed (33 C.F.R. 331.2); however, a PJD is
“preliminary” in the sense that an approved JD can be requested at any time. PJDs do
not expire.

I am requesting that the Corps provide an approved JD for the property identified herein.

An Approved Jurisdictional Determination (AJD) is a determination that
jurisdictional “waters of the United States” or “navigable waters of the United
States” are either present or absent on a site. An approved JD identifies the limits of
waters on a site determined to be jurisdictional under the Clean Water Act and/or
Rivers and Harbors Act. Approved JDs are sufficient as the basis for permit
decisions. AJDs are appealable (33 C.F.R. 331.2). The results of the AJD will be
posted on the Corps website. A landowner, permit applicant, or other “affected
party” (33 C.F.R. 331.2) who receives an AJD may rely upon the AJD for five years
(subject to certain limited exceptions explained in Regulatory Guidance Letter 05-
02).

I am unclear as to which JD I would like to request and require additional information
to inform my decision.

G. ALL REQUESTS

review area.

Size of Property or Review Area acres.

The property boundary (or review area boundary) is clearly physically marked on the site.
