landmarks such as towns, rivers, and roads. Also provide a detailed site plan showing property
boundaries and development plans in relation to surrounding properties. Both the vicinity map
and site plan must include a scale and north arrow. The specific footprints of all buildings,
impervious surfaces, or other facilities must be included. If possible, the maps and plans should
include the appropriate USGS Topographic Quad Map and NRCS Soil Survey with the property
boundaries outlined. Plan drawings, or other maps may be included at the applicant's discretion,
so long as the property is clearly defined. For administrative and distribution purposes, the
USACE requires information to be submitted on sheets no larger than 11 by 17-inch format;
however, DWQ may accept paperwork of any size. DWQ prefers full-size construction
drawings rather than a sequential sheet version of the full-size plans. If full-size plans are
reduced to a small scale such that the final version is illegible, the applicant will be informed that
the project has been placed on hold until decipherable maps are provided.

9. Describe the existing conditions on the site and general land use in the vicinity of the project
at the time of this application: The site has been in agriculture for many nears; prior to
development, the site was supporting cattle. Land use in the vicinity of this site is a
mix of residential development, agriculture, and forestland.
10. Describe the overall project in detail, including the type of equipment to be used: The
previously approved project consisted of the construction of a low density housing
development that included the approval of infrastructure roads and dam
maintenance.
This application is requesting the construction of piers for the individual homeowners
along with one boat ramp. Pilings will be installed by hand in the shallow areas of
the lake or by utilizing specialized pile driving equipment by barge in the deeper
areas of the lake. All access paths to piers through the buffers will be designed to
avoid large trees and other desirable vegetation, therefore large equipment will not
be needed within the riparian areas.
1 1. Explain the purpose of the proposed work: The purpose of the proposed work is to
provide water access for the homeowners within the previously approved residential
development.
IV. Prior Project History
If jurisdictional determinations and/or permits have been requested and/or obtained for this
project (including all prior phases of the same subdivision) in the past, please explain. Include
the USACE Action ID Number, DWQ Project Number, application date, and date permits and
certifications were issued or withdrawn. Provide photocopies of previously issued permits,
certifications or other useful information. Describe previously approved wetland, stream and
buffer impacts, along with associated mitigation (where applicable). If this is a NCDOT project,
list and describe permits issued for prior segments of the same T.I.P. project, along with
construction schedules. S&EC was retained in September 2004 to delineate jurisdictional
wetlands and streams on the site. On March 14, 2005, Mr. Michael Horan of the NC-
DWQ confirmed the applicability of the Tar-Pamlico buffers to streams throughout the
project. Due to an oversight, Mr. Horan revised the buffer letter on February 6, 2006. A
copy of Mr. Horan's revised letter is attached (TPRRO#05-0070). Ms. Jean Manuel of
the USACE met S&EC personnel on-site to review our delineation and determine
stream importance classifications on Mav 18, 2005.
On July 5, 2006, the applicant received an Approval of 401 Water Quality Certification,
Approval of Isolated Wetlands Permit and Authorization Certificate per the Tar-Pamlico
Buffer Protection Rules (see attached DWQ #06-0658). On Mav 22, 2006, the applicant
also received a 404 Nationwide Permit Verification, (see attached Action ID 200520995
& 200620803). The below tables include impacts approved by the NCDWQ and the
USACE.

VI. Proposed Impacts to Waters of the United States/Waters of the State
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
wetlands, open water, and stream channels associated with the project. Each impact must be
listed separately in the tables below (e.g., culvert installation should be listed separately from
riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts,
permanent and temporary, must be listed, and must be labeled and clearly identifiable on an
accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial)
should be shown on a delineation map, whether or not impacts are proposed to these systems.
Wetland and stream evaluation and delineation forms should be included as appropriate.
Photographs may be included at the applicant's discretion. If this proposed impact is strictly for
wetland or stream mitigation, list and describe the impact in Section VIII below. If additional
space is needed for listing or description, please attach a separate sheet.
1. Provide a written description of the proposed impacts: There are no proposed impacts to
jurisdictional waters within this application request.
2. Individually list wetland impacts. Types of impacts include, but are not limited to
mechanized clearing, grading, fill, excavation, flooding, ditching/drainage, etc. For dams,
separately list impacts due to both structure and flooding.

impacts. Stream impacts include, but are not limited to placement of fill or culverts, dam
construction, flooding, relocation, stabilization activities (e.g., cement walls, rip-rap, crib
walls, gabions, etc.), excavation, ditching/straightening, etc. If stream relocation is proposed,
plans and profiles showing the linear footprint for both the original and relocated streams
must be included. To calculate acreage, multiply length X width, then divide by 43,560.

7. Isolated Waters
Do any isolated waters exist on the property? ®Yes ^ No
Describe all impacts to isolated waters, and include the type of water (wetland or stream) and
the size of the proposed impact (acres or linear feet). Please note that this section only
applies to waters that have specifically been determined to be isolated by the USAGE. There
are no proposed impacts to isolated waters onsite.
8. Pond Creation
If construction of a pond is proposed, associated wetland and stream impacts should be
included above in the wetland and stream impact sections. Also, the proposed pond should
be described here and illustrated on any maps included with this application.
Pond to be created in (check all that apply): ^ uplands ^ stream ^ wetlands
Describe the method of construction (e.g., dam/embankment, excavation, installation of
draw-down valve or spillway, etc.): N/A
Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond,
local stormwater requirement, etc.): N/A
Current land use in the vicinity of the pond: N/A
Size of watershed draining to pond: N/A Expected pond surface area: N/A
VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It maybe useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts. The applicant is proposina to
construct all piers by barae in the deeper portions of the lake and by hand in the shallow
areas of the lake to avoid additional temporary impacts of the riparian buffers. All
Page 6 of 10

vegetation to be removed for access paths will be minimized by identifying the
boundaries of the paths before construction therefore avoiding the removal of large
trees or other desirable vegetation. The boat ramp is actually a replacement of an
existing boat ramp. The existing boat ramp is located on lot 46 and therefore not
accessible to all homeowners. In addition, the existing boat ramp is concrete and does
not represent the "natural" look the applicant is trying to achieve. The replacement boat
ramp is to be designed to follow the natural contours of the land and to be as
indistinguishable as possible. The applicant is proposing the use of GrasspaveZ as the
boat ramp, basically reinforced, recycled plastic matting that will allow vegetation
(grass) to prow within the rings and esthetically look like natural grass instead of a
typical hard structure. Please also see attached "Hidden Lake Individual Lot Pier
Construction Narrative and Request for Tar-Pamlico River Basin Riparian Buffer
Impacts" provided by the applicant along with product information for Grasspave2.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on January 15, 2002, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete.
An applicant may also choose to review the current guidelines for stream restoration in DWQ's
Draft Technical Guide for Stream Work in North Carolina, available at
http : //h2o.enr.state.nc.us/ncwetlands/strmgide.html.
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
Page 7 of 10

Because no impacts are proposed to jurisdictional areas, no stream or wetland
mitigation is proposed. Additionally, the riparian buffer impacts proposed are
considered "allowable" therefore no riparian buffer mitigation is proposed, please
see section X.3 for details.
2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement
Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at
[phone] to determine availability, and written approval from the NCEEP indicating
that they are will to accept payment for the mitigation must be attached to this form. For
additional information regarding the application process for the NCEEP, check the NCEEP
website at http://h2o.enr.state.nc.us/wrp/index.htm. If use of the NCEEP is proposed, please
check the appropriate box on page five and provide the following information:
Amount of stream mitigation requested (linear feet): N/A
Amount of buffer mitigation requested (square feet): 0
Amount of Riparian wetland mitigation requested (acres): N/A
Amount ofNon-riparian wetland mitigation requested (acres): N/A
Amount of Coastal wetland mitigation requested (acres): N/A
IX. Environmental Documentation (required by DWQ)
1. Does the project involve an expenditure of public (federal/state/local) funds or the use of
public (federal/state) land? Yes ^ No
2. If yes, does the project require preparation of an environmental document pursuant to the
requirements of the National or North Carolina Environmental Policy Act (NEPA/SEPA)?
Note: If you are not sure whether a NEPA/SEPA document is required, call the SEPA
coordinator at [phone] to review current thresholds for environmental documentation.
Yes ^ No ^
3. If yes, has the document review been finalized by the State Clearinghouse? If so, please
attach a copy of the NEPA or SEPA final approval letter. Yes ^ No ^
X. Proposed Impacts on Riparian and Watershed Buffers (required by DWQ)
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
required state and local buffers associated with the project. The applicant must also provide
justification for these impacts in Section VII above. All proposed impacts must be listed herein,
and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a
map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ
Regional Office may be included as appropriate. Photographs may also be included at the
applicant's discretion.
1. Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233
(Neuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 02B .0243 (Catawba) 15A NCAC
2B .0250 (Randleman Rules and Water Supply Buffer Requirements), or other (please
identify )? Yes ® No ^
Page 8 of 10

2. If "yes", identify the square feet and acreage of impact to each zone of the riparian buffers.
If buffer mitigation is required calculate the required amount of mitigation by applying the
buffer multipliers.

3. If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e.,
Donation of Property, Riparian Buffer Restoration /Enhancement, or Payment into the
Riparian Buffer Restoration Fund). Please attach all appropriate information as identified
within 15A NCAC 2B .0242 or .0244, or .0260. Riparian buffer impacts proposed are to
activities defined as Water dependent structures and are considered an "allowable"
use within the NCAC 02B .0259(6): Table of uses, therefore mitigation is not
required.
XI. Stormwater (required by DWQ)
Describe impervious acreage (existing and proposed) versus total acreage on the site. Discuss
Stormwater controls proposed in order to protect surface waters and wetlands downstream from
the property. If percent impervious surface exceeds 20%, please provide calculations
demonstrating total proposed impervious level. The previous submittal and approval
identified the impervious percentage to be 8%. All diffuse flow requirements will be met.
XII. Sewage Disposal (required by DWQ)
Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of
wastewater generated from the proposed project, or available capacity of the subject facility. The
development will connect to an existing sanitary sewer system. The municipality will
ensure that this development does not exceed the available capacity of the facility.
XIII. Violations (required by DWQ)
Is this site in violation of DWQ Wetland Rules (15A NCAC 2H .0500) or any Buffer Rules?
Yes ^ No
Page 9 of 10

Is this an after-the-fact permit application? Yes ^ No
XIV. Cumulative Impacts (required by DWQ)
Will this project (based on past and reasonably anticipated future impacts) result in additional
development, which could impact nearby downstream water quality? Yes ^ No
If yes, please submit a qualitative or quantitative cumulative impact analysis in accordance with
the most recent North Carolina Division of Water Quality policy posted on our website at
http://h2o.enr.state.nc.us/ncwetlands. If no, please provide a short narrative description: We
have reviewed the "DRAFT Internal Policy, Cumulative impacts and the 401 Water
Quality Certification and Isolated Wetland Programs" document prepared by the NC
Division of Water Quality on October 3, 2002, version 1.6. The proposed project does
not require a 401 Water Quality Certification or Isolated Wetlands Permit therefore
according to the NCDWQ Draft Internal Policy, a qualitative or quantitative impact
analysis should not be required.
XV. Other Circumstances (Optional):
It is the applicant's responsibility to submit the application sufficiently in advance of desired
construction dates to allow processing time for these permits. However, an applicant may
choose to list constraints associated with construction or sequencing that may impose limits on
work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and
Threatened Species, accessibility problems, or other issues outside of the applicant's control).
v Applicant/Agent's Signature Date

Approval of 401 Water Quality Certification, Approval of Isolated Wetlands Permit and
Authorization Certificate per the Tar-Pamlico River Buffer Protection Rules (15A NCAC 2B .0259)
with Additional Conditions -SECOND REVISION
Dear Mr. Garrett:
You have our approval, in accordance with the attached conditions and those listed below, to place fill
within or otherwise impact 0.2947 acres of wetland, 250 linear feet of perennial stream, 5 linear feet of
previously impacted temporary isolated stream, 0.1372 acres of open water, and 26,592 square feet of
Zone 1Tar-Pamlico River basin protected riparian buffers and 24,205 square feet of Zone 2Tar-Pamlico
River basin protected riparian buffers to construct the proposed residential subdivision and commercial
site as described within your application dated April 17, 2006, and received by the N.C. Division of
Water Quality (DWQ) on April 17, 2006, with additional information received by the DWQ on May 9,
2006. After reviewing your application, we have decided that the impacts are covered by General Water
Quality Certification Number(s) 3494 and 3404 (GC3494 and GC3404). The Certification(s) allows you
to use Nationwide Permit(s) 3 and 14 (NW 3 and NW 14) when issued by the US Army Corps of
Engineers (USAGE). This Certification replaces the Certification issued to you on June 5, 2006.
This letter shall also act as your approved Authorization Certificate for impacts to the protected riparian
buffers per 15A NCAC 2B .0259. In addition, you should obtain or otherwise comply with any other
required federal, state or local permits before you go ahead with your project including (but not limited
to) Erosion and Sediment Control, and Non-discharge regulations. Also, this approval to proceed with
your proposed impacts or to conduct impacts to waters as depicted in your application shall expire
upon expiration of the 404 or CAMA Permit. The Isolated Wetlands Permit will expire upon the
expiration date of IWGP100000 (September 30, 2008) or unless otherwise rescinded by the Director
of the Division of Water Quality.
This approval is for the purpose and design that you described in your application. If you change your
project, you must notify us and you may be required to send us a new application. If the property is sold,
the new owner must be given a copy of this Certification and approval letter and is thereby responsible for
complying with all conditions. If total fills for this project (now or in the future) exceed one acre of
wetland or 1501inear feet of stream, compensatory mitigation may be required as described in 15A
NCAC 2H .0506 (h). This approval requires you to follow the conditions listed in the attached
certification and any additional conditions listed below.

Sediment and Erosion Control:
2. Erosion and sediment control practices must be in full compliance with all specifications governing
the proper design, installation and operation and maintenance of such Best Management Practices in
order to protect surface waters standards:
a. The erosion and sediment control measures for the project must be designed, installed,
operated, and maintained in accordance with the most recent version of the North Carolina
Sediment and Erosion Control Planning and Design Manual.
b. The design, installation, operation, and maintenance of the sediment and erosion control
measures must be such that they equal, or exceed, the requirements specified in the most
recent version of the North Carolina Sediment and Erosion Control Manual. The devices
shall be maintained on all construction sites, borrow sites, and waste pile (spoil) projects,
including contractor-owned or leased borrow pits associated with the project.
c. Sufficient materials required for stabilization and/or repair of erosion control measures and
stormwater routing and treatment shall be on site at all times.
3. No waste, spoil, solids, or fill of any kind shall occur in wetlands, waters, or riparian areas beyond the
footprint of the impacts depicted in the 404/401 Permit Application. All construction activities,
including the design, installation, operation, and maintenance of sediment and erosion control Best
Management Practices, shall be performed so that no violations of state water quality standards,
statutes, or rules occur;
4. Sediment and erosion control measures shall not be placed in wetlands or waters to the maximum extent
practicable. If placement of sediment and erosion control devices in wetlands and waters is
unavoidable, they shall be removed and the natural grade restored within six months of the date that the
Division of Land Resources has released the project;
5. Protective Fencing -The outside buffer, wetland or water boundary and along the construction corridor
within these boundaries approved under this authorization shall be clearly marked with orange warning
fencing (or similar high visibility material) for the areas that have been approved to infringe within the
buffer, wetland or water prior to any land disturbing activities to ensure compliance with 15 NCAC 2H,
Section .0500;
6. Deed Notifications -Deed notifications or similar mechanisms shall be placed on all retained
jurisdictional wetlands, waters and protective buffers in order to assure compliance for future
wetland, water and buffer impact. These mechanisms shall be put in place prior to impacting any

Crescent Resources

wetlands, waters and/or buffers approved for impact under this Certification Approval and
Authorization Certificate. A sample deed notification can be downloaded from the 401/Wetlands Unit
web site at http;//h2o.enr.state.nc.us/ncwetlands. The text of the sample deed notification may be
modified as appropriate to suit to this project;
7. Culvert Installation
Culverts required for this project shall be installed in such a manner that the original stream profiles
are not altered. Existing stream dimensions (including the cross section dimensions, pattern, and
longitudinal profile) must be maintained above and below locations of each culvert. Culverts shall be
designed and installed to allow for aquatic life movement as well as to prevent head cutting of the
streams. If any of the existing pipes are or become perched, the appropriate stream grade shall be re-
established or, if the pipes installed in a perched manner, the pipes shall be removed and re-installed
correctly.
Culvert(s) shall not be installed in such a manner that will cause aggradation or erosion of the stream
up or down stream of the culvert(s). Existing stream dimensions (including the cross section
dimensions, pattern and longitudinal profile) shall be maintained above and below locations of each
culvert.
Placement of culverts and other structures in waters, streams, and wetlands must be placed below the
elevation of the streambed by one foot for all culverts with a diameter greater than 48 inches, and 20
percent of the culvert diameter for culverts having a diameter less than 48 inches, to allow low flow
passage of water and aquatic life. Design and placement of culverts and other structures including
temporary erosion control measures shall not be conducted in a manner that may result in dis-
equilibrium of wetlands or streambeds or banks, adjacent to or upstream and down stream of the above
structures. The applicant is required to provide evidence that the equilibrium shall be maintained if
requested in writing by DWQ.
The establishment of native, woody vegetation and other soft stream bank stabilization techniques
must be used where practicable instead of rip rap or other bank hardening methods. If rip-rap is
necessary, it shall not be placed in the stream bed, unless specifically approved by the Division of
Water Quality.
Installation of culverts in wetlands must ensure continuity of water movement and be designed
to adequately accommodate high water or flood conditions.
Upon completion of the project, the Applicant shall complete and return the enclosed "Certificate of
Completion" form to notify NCDWQ when all work included in the §401 Certification has been
completed. The responsible party shall complete the attached form and return it to the 401/Wetlands
Unit of the NC Division of Water Quality upon completion of the project. Please send photographs
upstream and downstream of each culvert site to document correct installation along with the
Certificate of Completion form.
8. Diffuse Flow (No Review)
All constructed stormwater conveyance outlets shall be directed and maintained as diffuse flow at
non-erosive velocities through the protected stream buffers such that it will not re-concentrate before
discharging into a stream as identified within 15A NCAC 2B .0233 (5). If this is not possible, it may
be necessary to provide stormwater facilities that are considered to remove nitrogen. This may require
additional approval from this Office.

Crescent Resources

9. Compensatory Mitigation Using the Ecosystem Enhancement Program (EEP)
Mitigation must be provided for the proposed impacts as specified in the table below. We
understand that you wish to make a payment to the Wetlands Restoration Fund administered
by the NC Ecosystem Enhancement Program (EEP) and donation of perpetual conservation
easements to meet this mitigation requirement. This has been determined by the DWQ to be a
suitable method to meet the mitigation requirement. Until the EEP receives and clears your check
(made payable to: DENR -Ecosystem Enhancement Program Office), and the EEP and DWO
approve the conservation easement donation, no impacts specified in this Authorization
Certificate shall occur. The EEP should be contacted at [phone] if you have any questions
concerning payment into a restoration fund. You have one month from the date of this approval to
make this payment. For accounting purposes, this Authorization Certificate authorizes payment
into the Wetlands Restoration Fund to meet the following compensatory mitigation
requirement:

10. Upon completion of all work approved within the 401 Water Quality Certification or applicable
Buffer Rules, and any subsequent modifications, the applicant is required to return the attached
certificate of completion to the 401/Wetlands Unit, North Carolina Division of Water Quality, 1650
Mail Service Center, Raleigh, NC, 27699-1650.
Violations of any condition herein set forth may result in revocation of this Certification and may result in
criminal and/or civil penalties. The authorization to proceed with your proposed impacts or to conduct
impacts to waters as depicted in your application and as authorized by this Certification shall expire upon
expiration of the 404 or CAMA Permit. The authorization to proceed with your proposed impacts or to
conduct impacts to isolated waters as depicted in your application and as authorized by this Permit, shall
expire upon expiration of IWGP100000 (September 30, 2008) or unless otherwise rescinded by the
Director of the Division of Water Quality.
If you do not accept any of the conditions of this Certification (associated with the approved wetland or
stream impacts), you may ask for an adjudicatory hearing. You must act within 60 days of the date that
you receive this letter. To ask for a hearing, send a written petition, which conforms to Chapter 150B of
the North Cazolina General Statutes to the Office of Administrative Heazings, 6714 Mail Service Center,

That was my mistake. The verification should have a '14' next to the '3' on page 1 at the end of the 'Authorization'

Eric,
Please review the 404 you issued and let me know which NWP you are issuing for the
open water, wetland and stream impacts associated with road construction for the
subdivision. We applied for a NWP i4, but I could not find a reference to the specific
permit authorized except in the mitigation impact table. However, the road impacts did
not have a permit number listed in the table on page 2 of the attachment. DWQ issued
GC 3404, which corresponds to NWP i4.
Thanks for your attention to this.

Re: Hidden Lake
Individual Lot Pier Construction Narrative and
Request for Tar-Pamilco River basin riparian buffer impacts
FAX [phone]
This narrative describes the subject property and our request to impact riparian
buffers around Hidden Lake for the purpose of accessing water dependent pier
structures for lake front properties.
Cedar Lake is a 588 acre exclusive residential neighborhood designed around a
central, man-made lake with a surface area of about 75 acres. Approximately 227 acres
are undeveloped, including a 100-acre natural wildlife preserve. Crescent Communities
(Crescent), in partnership with Audubon International has designed and developed the
property with a focus on the preservation of wildlife habitat, aquatic life and habitat, and
protection of water quality. Audubon International has awarded Hidden Lake a Triple
Diamond Certification, the highest certification possible. Crescent was the first
developer in the world to receive a triple diamond certification for• the Sanctuary on Lake
Wylie in Charlotte, North Carolina.
Audubon International and Crescent developed a "Green Book," an owner's
handbook that will guide landowners within the neighborhood on ways they can design
their homes and plan their lot development to minimize impacts to the lake and
surrounding land. Crescent has chosen to limit the property owners' ability to construct
lake access piers in order to preserve the natural beauty of the lake, to limit riparian
buffer impacts, and to preserve aquatic life and habitat. A mandatory pier design (see
Side-Long Fixed Pier, Typical Plan & Details prepared by OPDA, June 20, 2006) for the
owner's use is included in the Green book, and it is mandated that owners follow this
design in the neighborhood Covenants and Restrictions which are on file at the Franklin
County Register of Deeds.
Crescent has established a 50' conservation set back in addition to the minimum
50' Tar/Parnlico River Basin riparian buffer. Crescent will allow limited disturbance of
the conservation setback on a case by case basis, but will require compensatory planting

Hidden Lake
Page 2
August 28, 2007
for areas within the conversation buffer that are disturbed. Trees Z" in caliper and larger
within the conservation setback will be protected to the maximum extent practical.
Lake front property owners will be allowed to access the lake from their property.
Crescent has restricted the lake to canoes, kayaks, and small electric boats. The side-long
fixed pier design is intended to allow practical lake access for small, shallow draft boats.
Pier Construction will be carefully planned for each lot to minimize buffer
impacts, Generally, all piers will be constructed from tlae water, either manually in
shallow areas or from a barge in deeper parts of the lake. In any case, cot~struetion from
the shoreline will not be allowed. Bulkheads will not be allowed in any circumstance.
Pilings will be installed by-hand in shallow areas (ie. less than 3 feet deep) and by
barge with a specialized pile driving apparatus. Access to the shoreline will be by foot
traffic only. Buffer disturbance will be limited to the area where the access way connects
to tl-te shoreline (estimated to be 1 S square feet for each pier, and considered impervious)
and the area needed to install a pervious mulch path through the buffer and conservation
setback.
The access path through the buffer will be laid out prior to construction to avoid
large trees or other desirable vegetation as well as following existing contours to
minimize erosion. Upon completion of the piers, access paths through buffer areas will
be limited to three feet wide and must be of pervious materials such as wood chips or
mulch.
Included with this application is a request to remove an existing concrete boat
ramp (located on Lot 46.) Crescent proposes to locate the pier for lot 46 within the area
that will be disturbed by removal of the concrete ramp. Areas beyond those necessary for
the pier and access way will be restored by planting native trees and under-story
vegetation. Anew ramp will be constructed on property that will be maintained by the
Property Owners Association. The new ramp will be constructed using the Grasspave2
porous pavement system (see attached) in order to minimize buffer impacts and
maximize infiltration and vegetation tnowth. Soils below the normal pool elevation are
dense and sandy due to previous livestock operations and should be adequate to support
loads imposed by light and infrequent boat trailer traffic. Currently, the buffer in the area
proposed for the boat ramp is pasture from previous livestock operations on the property.
Crescent expects this ramp to be used infrequently since the size and type of boats are
restricted to electric boat that are less than 10 feet in length. It is not feasible to service
electric boats in the water and there are no other provisions to remove electric boats from
the lake for service. The lake water level will be drawn down about 1 foot temporarily
for construction of the Grasspavez system, however, platming and efficient installation
will minimize the time the lake level will be below normal pool.

A tabulation of proposed buffer impacts has been included with this application
and specifies the amount of buffer impact in Zone 1 and Zone 2 of the buffer for each lot.
The table also summarizes pervious and impervious buffer impacts.

Grasspave2 Installation Procedures
This installation section is only intended as an overview. Please
review our Grasspave2 Technical Specifications (available at
www.invisiblestructures.com or ca11 800-233-1 51 0) for
comprehensive installation instructions.
Excavate a space for the base course as determined by site soils
and loading requirements. Place and compact sandy gravel which
should be a mixture of clean sharp sand and gravel varying in size
but not exceeding 3 4 of an inch. To check porosity, use a hose to see
that water flows into the base and drains away. Add subsurface
drainage as necessary to low spots or locations with poor draining
soils. Install irrigation lines and sprinkler heads if necessary.
Apply the Hydrogrow mixture that is included
free with your order. Hydrogrow is a mix-
ture of polymer and fertilizer
~~'~ designed especially for our
~~, ,;, Grasspave2 system.
Roll out Grasspave2, aligning the side hole fasteners over the
side pegs. The warmth of the sun will relax the plastic so it lays
flat. Cut the grid between rings using pruning shears. Incorporate
the cut pieces in other areas, as needed, keeping the distance
between the rings uniform.
Fill rings with clean sharp concrete sand (AASHTO M6 or ASTM
C-33) using large rakes and brooms so that the tops of the rings
show when done.
Lay turf over the rings. On warm days, wet the sand first to lower
sand temperature and provide moisture for grass roots. Seeding
and hydromulching is also an accepted vegetating method at this
stage. Repeated hydromulching/seeding may be necessary.
Roll sod with heavy roller to eliminate air pockets and make
sure roots are in contact with the sand fill. Water lawn as usual
according to climatic requirements.
Whether the area has been seeded or sodded, wait to drive on
grass until two mowings have been completed, by which time
the root system will be established and the sod pieces locked
into place. In an emergency such as the need for fire truck
access, grass may be driven on immediately after installation.
Use a regular lawn mower for maintenance. There should be
no paver parts protruding through the surface that would
damage mowers. Do not aerate!

may vary).
Gravelpave2 Installation-
Gravelpave2 Size/Shape Fill Requirements
You will need 1" of gravel fill, compacted. Be
careful to order enough far the compaction
process and choose a gravel size that will nest
well into the rings. We have found that 3 ~h' minus
crushed stone and sometime 3/x' with limited
small sharp screenings (#40 to #100 screen) works
well. Washed gravel will roll within the rings
and will also "roll about." For this reason, we do
not recommend pea gravel, even though it is
often very attractive. A visit to your local quarry
is suggested. We have found that some geological
areas of the United States have limited types of
sharp gravel available. It has been necessary to
import gravel from a neighboring state, but
remember the amounts are relatively small-
the top one-and-a-quarter inch of the cross sec-
tion. Gravel should be as free of fines as possible.
To maintain porosity, avoid soft stone materials
with low durability that will break easily.
Other Fill Materials for Gravelpave2
Please ask our staff for assistance with this
category since it is use-specific and often experi-
mental. Ground rubber, crushed glass, crushed
brick, and many other materials can be useful as
attractive fill materials for various applications.
Thermoset (epoxy, polyurethane, etc.) binders may
be cost prohibitive for most projects, but offer
unique design possibilities, including clarity, color
enhancement (wet look), flexibility and durability.
Our technical support staff will assist with
selection of gravel sources. The photographic
samples shown on this page will help you narrow
your gravel choices. Should you have questions
concerning the selection, please submit a small
sample for approval prior to specifying
or securing the materials.

GravelpaveZ Installation Procedure
This installation section is only intended as an overview. Please
review our Gravelpavez Technical Specifications (available at
www.invisiblestructures.com or ca11800-233-1510) for
comprehensive installation instructions.
Prepare sandy gravel base course to a depth as determined
by a soils engineer. Compact with a vibrating plate compactor or
use a heavy motorized roller for large jobs. To test porosity, water
with a hose and check to see that water drains readily through
the base course before installing the GravelpaveZ mats.
Roll out mats with the grain (in the same direction) so that
the snap fit fasteners can be used with neighboring mats. To
fit around boxes and curbs, cut the grid between the rings with
pruning shears and scissors or a small portable electric hand saw.
Fasten the mats together using the snap fit fasteners that are
molded into the product inserting the prongs into the rectangular
openings. Tuck the fabric underneath the fasteners to keep joints
closed. Aquarter-inch nut driver head (6 mm) fits nicely over the
fastener to compress the pieces together. A piece of lumber placed
under the GravelpaveZ mat will provide stability to aid in fastening.
11
process. Anchors should be placed inside the rings as close to
the center as possible. Begin anchoring from one corner in a
radial pattern.
Gradually place gravel fill (see suggested fill material on facing
page) into rings by using afront-end loader and shaking out the
fill as the machine drives forward. Carefully lower the bucket
when empty and back up while dragging it above the rings to
smooth out the gravel, finishing with a stiff broom. Wheel barrow
and shovel works well for small jobs. Contractor tip- you can
store excess material for future maintenance, top dressing as
may be necessary. Use rakes and/or push brooms to distribute
the gravel fill to a level slightly above rings so that compacting
the fill will not uncover the rings.
Use a vibrating plate compactor or large driving roller again to
compact the gravel fill. Additional gravel may be necessary to
finish filling the rings. Compact again until the material appears
solid in the rings. Wetting the gravel may help it to interlock.
Drive on the installation when finished. If car tires make a
pattern, there may be too much gravel or it may need additional
compaction. It is expected that tops of the rings may be visible.
If sides of the rings show, then add more fill material and repeat
the compaction process.

Golf Industry
Gravelpavez and GrasspaveZ golf cart paths give the look of a
natural path through trees, along fairways, and around greens.
The flush surface requires no trimming or edging. Traction is
excellent with Gravelpavez and GrasspaveZ traction is slightly
better than grass. GrasspaveZ
and Gravelpavez can enhance
your golf cart staging area,
pedestrian traffic area, parking
lot, road shoulder, and mainte-
nance yard.
Automobile Dealership Displays
Car dealerships have discovered
that GrasspaveZ and Gravelpavez
are perfect for automobile dis-
play areas. Dealerships now
have an option when it comes
to adding paved areas for car
transport and display. Dealerships
like the °soft" attractive look grass
and decorative gravel provide.
Utility and Maintenance Vehicle Access
Providing your site with impor-
tant utilitarian functions with-
out compromising beauty
is simple. GrasspaveZ and
Gravelpavez can incorporate a
structural road without inter-
rupting your landscaping. No
obtrusive concrete or asphalt
access roads are necessary to
get to window washing areas,
pump stations, microwave tow-
ers, tanks, or electrical boxes.
Unique Applications
Our mats are installed in some
unique and interesting places:
Helicopter landing pads, race car
display areas, outdoor amphithe-
ater seating, under picnic tables,
under concrete pavers (support),
airplane display and transport,
cemetery marker reinforcement,
eave drip lines and more.
Installations are not limited
to traditional paved areas.
GrasspaveZ Characteristics

Large Rolls
Our patented systems have a shipping, handling and installation
advantage as well- large rolls. Our standard roll size (model
2020) covers 431 sq. ft. (40 mz) and weighs 192 pounds (87 kg).
Other roll sizes are available. Installers of our products have
repeatedly commented that they

enjoy the easy installation.
Rolling out GrasspaveZ is
similar to rolling out carpeting
and coverage is fast and effi-
cient. The mat system can be
easily cut to fit around trees,
irrigation, curbing, or other
terrain. The rolls have snap-fit
connectors to attach to adjacent
rolls, making one unified, con-
tiguous system. This unified
mat system adds stability and
continuity in design. GrasspaveZ
can just as easily be snapped to
Gravelpavez to add stability and
product variation.
Hydrogrow
Another reason GrasspaveZ
is the industry leader is the
addition of Hydrogrow soil
amendment, which is supplied
with your order. Hydrogrow is
engineered to help grass grow
in our sand based root zone.
The results are amazing and
our GrasspaveZ areas often
look healthier than surrounding
turf. By using this special mix-
ture in the sand, porosity will
be maintained, turf will be
attractive, and aeration will
not be necessary.
Sand Fill
GrasspaveZ is the only grass
paver on the market specifying
sand as part of its cross section.
Sand is the best medium to pro-
vide water and air to the roots
and still provide high compres-
sive strength. The United States

Ring and Grid Structure
GrasspaveZ is by most accounts the best flexible grass paver
made today. Its unique ring and grid structure allow for flexibility,
stability, and exceptional grass growth. With 92 percent void
space for healthy roots and 100 percent grass coverage, GrasspaveZ
is the industry's preeminent choice. Our installations are hard to
find because they are invisible! With so little plastic near the
crown of the grass, the blades of grass are not smashed by prod-
uct. Root development is not interrupted from spreading laterally.
The rings are strong and rigid, keeping grass root systems pro-
tected from harm. The roots grow directly downward, deep into
the sandy gravel base course.
Golf Assoctatton uses sand for
every USGA golf course and nearly every professional and colle-
giate turf athletic field uses a sand cross section as well. Topsoil (or
other organics fill material) in the rings will eventually compact
and damage the root zone. Sand negates the need for mechanical
aeration, which can damage GrasspaveZ and other grass pavers.
Strength When Installed
When installed over a thick base course and compacted to 95
percent modified Proctor, sand-filled rings can support 5,700
pounds per square inch (psi) without deflection or compromise to
safety. The cylinder is the strongest shape to support compressive
loads because it has no corners. Supporting heavy loads with the
rings allows us to use less plastic in the product creating a 92
percent void area for root development, combined with strength!
Less plastic means a lower cost for you.

Traffic Frequency
Grass as a surface material can withstand from two to six (varies
with grass species and environmental conditions) trips daily over
the same spot. This suggests that most parking applications we
pave with asphalt today could be paved with Grasspavez instead.
Vehicles can remain parked on grass for extended periods of
time, provided some relief can be given for a few days for the
grass to recover.
Lifespan
Grasspavez has a projected
lifespan of 60 years.
Compared to asphalt
with a lifespan of 15
years; and concrete
with a lifespan of 25
years, Grasspavez will
save you money on
replacement costs.
Irrigation
Grass needs water and you
may need to have irrigation
installed. Grasspavez has a sand
based root zone which usually
requires slightly more water than a
normal topsoil or organic root zone. If
golf courses in your area use irrigation
systems, you probably should in
your Grassapavez installation.
Gravelpave2 Characteristics
Fabric, Ring and Grid
When we developed
Gravelpavez in 1993, our
goal was to provide designers
a second option for a porous
pavement that can tolerate
high frequency and low-speed
traffic. By molding our ring
and grid structure onto a non-
woven polyester filter fabric,
we were able to create a new
product that contains gravel
and prevents particle migration
and rutting.

Rolls can be installed manually (L people advised). Rolls apply- to Grasspace~, Gravelpavez, Drauicorez,
and Slopetamez.
Gravelpave2 is the only system specifically designed for aggregate
containment porous paving. The cylinders displace the load onto an
engineered base course and hold the decorative gravel in place. The
fabric keeps the tap-dress gravel from compacting into the road
base, acts as a weed and vegetation barrier, and suppresses dust.
Traditional pavements, including gravel roads, are designed to
shed water and keep it away from the pavement's cross-section.
Gravelpavez is designed to do the opposite- welcoming water
down through the system. Plus, Gravelpave2 will not rut, wash-
board, or puddle like traditional gravel roads.
Snap-Fit Fasteners
Designed into Gravelpave2 is a snap-fit fastener, atwo-pronged
arrow that fits into a rectangular slot. Simply push the slot over
the prongs to easily snap together panels of Grasspavez. To take
them apart, just squeeze the prongs together and lift off the slot.
Should the fasteners of one mat not align over the distance of
another mat, then anchor pins (or eight inch ring shank nails and
large washers) can be used to secure the mats along the seam.
Forcing the alignment can cause the mats to ripple and not lay
down evenly.
Traffic Frequency
Gravelpavez has no limits on frequency or duration of traffic on
the system. Park or drive as often as you like on
Gravelpave2. However, speeds should be kept
at or below about 20 mph (30 km/h).
Durability
Grasspavez and Gravelpave2 are
made from flexible High Density
Polyethylene (HDPE) plastic
with UV inhibitors, which
withstands repeated

unaffected by extremes in pH. A well-
maintained Gravelpavez installation will
last 25 years in most climates.

designers to use Gravelpavez
is the ability to have an area
maintain a natural look. Many
times native soils or gravel can
be used as fill material, comple-
menting surrounding areas.
Gravelpavez is available in four
standard colors- black, tan,
gray, and terra cotta (custom
colors are available at addition-
al cost). Ring colors are intend-
ed to blend with the gravel
color so they will be less visible
should some portion of the rings
show A small amount of excess
stone fill should be left above the top of the rings to provide visu-
al cover and additional UV protection. This excess will migrate,
but usually not very far.
Size and Shape Requirements for Gravel Fill
You will need one and a quarter inch (3.2 cm) of gravel fill,
before compaction. After compaction the gravel should be only
be slightly higher than the rings (' 8 inch, 3 mm above). The
following criteria for gravel fill will make the most of the
systems performance:
• Hard- resistant to breaking, crushing or crumbling
• Sharp and angular (do not use rounded pea gravel)
• Clean, washed (free of fines)
• Size 3 ~e to 3 H inch (5 mm to 1 cm)
Other fill material may be used in certain situations, but may be
considered use-specific or experimental. Please consult with our
technical support staff regarding fill material not meeting the
above criteria or for installations requiring "binders."

Fire departments usually require you to plow snow that is over three
inches deep. (7.5 cm). Consult with your local fire department for their
guidelines.
Educate your snow removal crew to take care not to have the plow
blade make contact with the Grasspavez or Gravelpave2 systems.
Experienced snowplow drivers can leave a thin layer of snow on
the systems or they can attach skids (' 4 inch- 2 cm) to the bottom
of the blades.

Dust Suppression
Dirt and gravel roads have the potential to kick up dust and dirt
when traversed. Many communities have regulations limiting or
eliminating gravel surfaces from new construction. Rest assured,
if you design a GravelpaveZ surface
you will be getting a virtually dust-
free surface. The clean and washed
fill material required to fill the
rings will not have any more dust
than an asphalt-paved surface.
GravelpaveZ's geotextile fabric
will prevent the dust-sized particles
contained within the base material
(existing gravel surface or dirt),
from being displaced by moving
tire or wind forces.
Industry Advantages
Economic Advantages
Whether you are an engineer,
architect, landscape architect,
contractor or homeowner you will
be concerned with the cost of you
project. GravepaveZ and GravepaveZ
will save you money. Our products
will save on design costs, installa-
tion costs, component materials,
maintenance/operations expenses
and lifecycle costs. We can find a
way to reduce your site expenses
with our porous pavers.
rutting in [his ADA accessible trail.
When designing, you may be able to eliminate or reduce storm-
waterfilters, detention basins, conveyance lines, modifying
grading requirements, or many other "necessities" associated
with asphalt or concrete. A great deal of your stormwater
mitigation plan can be built into Grasspave2 and GravelpaveZ.
Installers have been astounded by the speed and efficiency
for which large areas can be accommodated by our large rolls.
Unrolling our mats, snap fitting, and cutting is easy and requires
no special machinery. Please view our technical specifications
(from wwwinvisiblestructures.com, call 800-233-1510, or avail-
able through our partner network) for the installation procedure.
A brief installation overview is also on pages 8 and 10).
Compacted sandygravel road base placed above compacted subgrade, 95% modified
Proctor density. GravelpaveZ rolls are laid, pinned, and filled with clean, sharp gravel.
In addition to cost savings in the design phase, you may be able
to eliminate other components during installation such as root
protection for trees, grates, manholes, curbing, and tree and
vegetation removal costs.
Maintenance and operations
costs are significantly reduced
over asphalt and concrete surfaces.
A. (Andy) E. Lindsey, Director of
Grounds Maintenance, University
of South Alabama, in his written
analysis dated February 18, 1999,
compared the cost of our porous
systems to asphalt pavement using
historical data from university
records. The conclusion was a
$56,000 savings over 20 years, by
using Grasspave2 and GravelpaveZ.
Our products can save you the most
money by combining your surfaces'
uses into one area. Multiple surface
use means savings on real estate,
design costs, maintenance, insur-
ance and more. You can have a fire
lane that doubles as "green space"
for employees or visitors, combine
a parking lot with a bio-swale and
stormwater mitigation system, and
expand your lawn into the driveway.
The GravepaveZ and GravelpaveZ
installations at Reliant Stadium,
Houston, Texas, pull quadruple
duty, providing over seven acres of
parking, stormwater mitigation, required "green space," and an
outdoor festival site which generate additional income.
As mentioned above, GravepaveZ and GravelpaveZ have a longer
lifespan than asphalt. Compound the above savings with the
longer lifespan, and you can have a lifecycle cost which can save
thousand of dollars on even moderately sized installations.
Competitive Advantages
Our porous pavers not only have advantages over impervious
surfaces, we are proud to compete with any other plastic porous
pavers manufactured. Our products are the strongest on the
market 5,721 psi installed (39,273 kl?a, 823,844 psf or 7,414,416

92 percent void space for the best root development and grass
coverage (GrasspaveZ) and the most volume available for desired
fill (GravelpaveZ). Most other plastic pavers come in rigid unit
blocks, which are cumbersome to install and difficult to cut
and shape. GrasspaveZ and GravelpaveZ rolls are considered
the favorite to work with by installers,
for the flexibility, continuity, and speed
of installations. GrasspaveZ is the only ~ =•~~°t=~~1 a~~ ~ • ~""
product on the market specifying sand
infill for the grass roots. Sand is recom-
mended as the infill of choice for grass
pavers by Professor Bruce K. Ferguson,
Univ. of Georgia, author of the book,
"Porous Pavements."
Competing Technologies
Porous paving technology has made
great strides not only in flexible plastic
pavers but in other areas as well.
Permeable asphalt, permeable con-
crete,interlocking unit blocks,rein-
forcement mats, and concrete grid
pavements, have all improved and
advanced to meet the growing demand
for environmentally friendly technolo-
gies. It is Invisible Structures' firm
belief that you should use porous
paving, even if it is not our product
line, whenever possible. The more
you use these technologies, the better
accepted they become: If you have to
pave, porous pave!
Invisible Structures also contends
that while these competing tech-
nologies have their place, in most
instances, our GrasspaveZ and
GravelpaveZ systems outperform,
last longer, require less maintenance,
look better, and are easier to install.
Check with our technical specialists
at 800-233-1510 for the latest data.
Designing for GrasspaveZ and
GravelpaveZ

Design for Use
There is an area in your development,
site, or home that will most likely ben-
efit from GrasspaveZ and GravelpaveZ.
We advise that you take a look at prop-
er use patterns, site conditions, and
other specifications to get full advan-
tage and long life out of our products. Invisible Structures,
800-233-1510, is available for preliminary design assistance and
consultation. Please note that other porous paving systems are
NOT interchangeable with GrasspaveZ or GravelpaveZ, consult
our technical specifications for full installation instructions.
Considerations for Design:
• High use, low speed, and unlimited traffic volume is optimal
for GravelpaveZ
• Low to moderate use, low speed, with recovery time is
perfect for GrasspaveZ or GravelpaveZ
If your site varies from these condi-
tions, please consult ISI directly,
800-233-1510, as some conditions
can be overcome with design and
component adjustments.
Base Course Design
Calculating the depth and composition
of materials for the base course incor-
...
porates the same design criteria as for
.. ,.. - .-.-.a.. .
other pavements:
• Load-bearing capacity of native (or
~' fill) subsoil,
• Plasticity or impact of moisture on
`- ~~ . strength and longevity,
fl I I~ Frostheave potential, and
• Traffic load, frequency and/or
duration.
• Sample Base Course Depths
Please consult with a soils engineer
.,~ . '~~ for site-specific base requirements.
Generally, the depth that is used under
asphalt will be the requirement under
GrasspaveZ/GravelpaveZ. Golf carts and
pedestrian traffic may require nothing
over sandy gravel soils, and just two to
four inches of base course (5- 10 cm) over very weak soils. Cars
usually need asix- to eight-inch base course (15- 20 cm). Buses,
trucks, and fire engines can easily require eight to 12 inches
(20- 30 cm) or more. The use of geotextiles, below the base is not
required, but will prevent integration with subsoils and is strong-
ly advised in areas of clay or silt soils and frost heave. Do not use
100 percent limestone base as limestone will compact and become
impervious-If limestone must be used, mix with 25-30 percent
sand (AASTO M6 or equal).

Bedding Sand Not Necessary
Do not use a sand setting base with our products. Unlike concrete
pavers, bricks, and other rigid pavers- our Grasspavez and
GravelpaveZ are flexible and do not require sand to level.
Edge Protection
For aesthetic and maintenance considerations, you may want to
design in a durable edging material to separate our porous
pavers from adjacent areas of turf or to simply delineate a fire
lane or path. With GravelpaveZ, an edging can prevent vegetation
from encroaching onto the system and can prevent the gravel fill
from migrating at the edge. Steel, aluminum, wood, brick, or con-
crete are all acceptable edging materials. Keep the edging flush
or slightly higher than the porous paver grade.
Maintenance and Operation
Grasspave2 Maintenance
Irrigation is required in dry climates. Any popular pop-up system
can be used. Simply cut out rings to reveal the irrigation head. If
golf courses in your area use irrigation systems, you probably
should in your Grasspavez installation. Be careful not to over-
water as this will encourage shallow root development.
Fertilize once a year with an NPK slow-release fertilizer that
contains trace elements. There are many brands on the market.
Do not aerate! You'll end up with product damage. When installed
using sand in the rings, there will not be a compaction problem.
Be careful not to use clay-based sods in pedestrian or vehicular
traffic areas- use sandy soil sod, or seed and mulch. There
Private Residence, Houston, TX
seems to be no problem with sod selection for fire lanes. If the
Grasspavez area has just been seeded or sodded, drive on it only
in an emergency.
Gravelpave2 Maintenance
Potholes will only appear if the base course has not been
compacted properly before laying the rings or if the base material
is allowed to mix into clay soils below (use nonwoven fabric to
keep separate). Should this occur, remove a section by vacuuming
the gravel from the rings, unfasten the snap fit fastener, bring
the base course to the proper grade and compaction, put the
Gravelpave2 square back in place, anchor, and fill to the top of
the rings. Seasonally check the rings in high-traffic areas and
entrance lanes for lower levels of fill and replace by sweeping
gravel from other areas to bring it level again. Leaves should be
raked or vacuumed and not allowed to decay. Organic matter will
stimulate weed growth and reduce porosity. To attack any occa-
sional weeds that may locate within the GravelpaveZ installation,
simply spray them with a weed killer (such as Roundup" )and
remove them when dead.
Cold Climate Concerns
Porous pavement thaws faster than conventional pavements
because it allows melted water to flow directly through the
pavement, increasing the temperature in the cross-section.
Grasspavez and GravelpaveZ are made from flexible High
Density Polyethylene (HDPE) plastic with UV inhibitors, which
withstands repeated freeze-thaw cycles and continuous subzero
temperatures without cracking.

Purpose: To provide a detailed explanation of the information required by the Division of Water Quality
in order to expedite the review of applications for 401 General Water Quality Certifications, Isolated
Wetland Permits, Stream and Wetland Mitigation Plans and Riparian Buffer Approvals (Please Note: do
not leave any questions unanswered or use terms such as "N/A" without an explanation).
Fees:
401 Water Quality Certifications: Major (>/= 150' stream or >/= 1 acre wetlands) $2,000.00
Minor (< 150' stream or < 1 acre wetlands) $1,000.00
Riparian Buffer Approval: (exclusively or "in addition" to) $2,000.00
Isolated Wetland Permit: General $1,000.00
Wetland & Stream Mitigation Plan: Major w/buffers (>/= 150' stream or >/= 1 acre wetlands) $4,000.00
Major w/o buffers (>/= 150' stream or >/= 1 acre wetlands) $3,000.00
Minor/buffers only $2,000.00
Please read the entire document before attempting to determine the proper fee. Fees are additive for
particular projects.
Things to keep in mind when filling out the application:
A specific answer must be provided for each question. For instance, if a numerical answer is requested
then a numerical answer must be provided along with the supporting information necessary for DWQ staff
to verify that the number is accurate. Likewise, if explanations are presented to justify certain responses,
the explanations must be completely supported by documentation. DWQ staff cannot assume that
unsupported or undocumented information is accurate. "N/A" is not an acceptable answer for any
question since the DWQ Staff reviewing the application must have an opportunity to determine whether or
not any requested information is pertinent.
All forms, guidance, worksheets, applications, etc. used must be the current versions as posted on our
web site at http: h2o.enr.state.nc.us/ncwetlands. There will soon be a web site specifically for the
express review program. Please note that it will be the applicant's or applicant's consultant's
responsibility to verify that the current versions are used. The versions posted on our web site will be
considered to be the current versions.
You are a very important part of the success of this program, if you have suggestions or clarifications
please send your comments to the Wetlands/401 Unit of the DWQ (via email at
401 express @ ncmail.net).
Filling Out the Pre-Construction Notification Application:
The Corps of Engineers (USAGE)/DWQ official, joint Pre-Construction Notification (PCN) App-ication
must be used as a basis for the expedited review process. The completed application should be
presented first and the supporting information tabbed and collated in the same order. Using a custom
format is not recommended. The open squares (fij are checklist items. The following items correspond to
the numbering system on the Pre-Construction Notification Form (PCN):

USE CHECK BOXES TO TRACK PROJECT INFORMATION
SECTION I. PROCESSING
-~ 1 & 2.The USACE determines which Nationwide, Regional, or General Permit is
required. If you have verified with the USACE which permit they intend to use for
your project or if you already have written approval from the USACE, please
indicate by adding "verified" or "verified, attached", respectively, in the blank next
to the Permit number requested.
~ Attach the USACE Approval if you have it.
C 3. It is not anticipated that the expedited process will be requested for this situation.
4. If you propose to impact 150 feet or more of perennial stream or 1 acre or more
of wetland and onsite mitigation is not proposed, it is recommended that you
either locate an acceptable private bank with available credits (with
documentation to show that the bank can and shall provide the credits needed)
or obtain approval from the EEP for the entire amount of stream and or wetland
as DWQ will make the final determination as to whether or not mitigation applies.
Please note that the USACE may have different mitigation requirements and
thresholds.
5. State whether your project will require a CAMA Minor, Major or General Permit
and give the status of the permit.
SECTION II - APPLICATION INFORMATION
1. 15 NCAC 2H .502(f) reads as follows; "Who Must Sign Applications. The application
shall be considered a "valid application" only if the application bears the signature of a
responsible officer of the company, municipal official, partner or owner. This signature
certifies that the applicant has title to the property, has been authorized by the owner to
apply for certification or is a public entity and has the power of eminent domain. Said
official in signing the application shall also certify that all information contained therein
or in support thereof is true and correct to the best of his knowledge."
Please indicate how the applicant meets the above definition and provide
supporting documentation.
-'~ Please provide all of the requested contact information including a fax
number and email address.
2. C~ If the application is not signed by the applicant, please attach the agent authorization.
The applicant must sign the agent authorization letter. The applicant's name and
position must also be spelled out as many signatures are difficult to read.
3. -i Please provide all of the requested contact information including a fax number and
email address.
SECTION III -PROJECT INFORMATION
The following is the most critical of all the information that you must provide. The quality and detail of the
information will often determine the expeditiousness of the review. The following is a checklist of the
types of pertinent information required at a minimum:

3
Maps and Plans:
The most recent version of the 1:24,000 USGS Topographic Map- Please cleanly
delineate the site boundaries, etc. on the map. If the delineation obscures any of the
features, it is recommended that a clean copy be provided. Please indicate the
quadrangle name. You can go to the USGS web site (http://mac.usgs.gov/maplistsn to
verify the most recent version.
The most recent version of the NRCS Soil Survey Map - (required for projects within
the Neuse River Basin, Tar-Pamlico River Basin, Randleman Lake Watershed and the
Catawba River Basin, also recommended for all projects) -Please cleanly delineate the
site boundaries, etc. on the map. If the delineation obscures any of the features, it is
recommended that a clean copy be provided. Please indicate the page or map number
from which the copy of the map was made. Copies of the current soil survey and/or soil
surrey map sheets can be obtained from the local NRCS County Office
(http://www.nc.nres.usda.gov~.
Vicinity map -Please clearly mark the location and approximate boundaries of the
property and project on the map. Please indicate north and scale. Please include
applicable road names or State Road numbers.
The Site Plan -The most critical map to be provided is the site plan. You must provide
full sized plans. The following is the minimum list of plans that are typically needed.
Pre-construction/Pre-existing conditions -This sheet must be scaled and
include all jurisdictional and non-jurisdictional wetland, stream, water features,
State regulated buffers, topographic contours with elevations, approximate extent
and nature of forest, field, landscaped, or other cover. Any existing structures and
impervious area must be shown. Existing utility lines and easements must be
shown. Existing roads, culverts, and other pertinent features must be shown. North
arrow and the scale must be shown. Please note that the impact boundaries on the
maps should correspond to the flagged impact boundaries in the field.
Proposed conditions -These sheets must be scaled and show all existing
jurisdictional and non-jurisdictional wetland, stream, water features, and State
regulated buffers must be underlain on the site plan(s). The plans must show all
built-out structures and impervious cover. The plans must include the final grading
contours with elevations. The plans must indicate all utilities and easements. It is
likely that several versions of the final built-out site plans will be necessary. The
following is a list of layers:
Drainage Plans -Final drainage plans must be included. The plans should include
the locations and pertinent elevations and sizes of the collection system and
drainage ways. All inlets and outlets must also be shown with pertinent elevations.
Scaled stormwater BMPs must also be indicated as required by DWQ rules and
policies. In certain cases, final stormwater management plans must also be
provided, but that will be addressed later in this document.
Plats -The plans must show the location and layout of all sub-divided parcels with
lot identifications. Platted parcels must be developable without further impacts to
jurisdictional and non-jurisdictional wetlands, streams, water features, and State
regulated buffers.
Proposed Impacts -All impacts to jurisdictional and non-jurisdictional wetland,
stream, water features, and State regulated buffers must be shown and labeled on
the site plans. All excavation, fill, flooding, stabilization, and other impacts that will
be conducted in or near jurisdictional and non-jurisdictional wetland, stream, water
features, and State regulated buffers must be indicated.

4
Wetland Impacts (on the site plan):
Precise grading and final elevation contours must be provided. Existing vegetation and
any clearing must be specified.
All subsurface utility lines must indicate the location of anti-seep collars. Construction
detail for anti-seep collars must be provided.
Roadway or other crossings of riparian wetlands may require floodway culverts to
maintain existing hydrological conditions.
When surface drainage features or groundwater recharge areas that feed or would
reasonably feed wetlands that are not to be filled are made impervious, it may be
necessary to direct some stormwater runoff to those areas in order to maintain hydrology.
You must identify these areas and address them. Supporting explanations and discharge
information must be provided to show that the wetland would not be eroded or receive
too much or too little hydrology. In many cases this could help satisfy part of a
stormwater management plan.
Flooding
Draining
Stream Impacts:
Stream impacts must be clearly shown on the plans. The centerline as well as the banks
of the stream must be surveyed or located by GPS for the portion of the stream to be
impacted.
Culverting:
The inlet and the outlet of the culvert should be aligned with the stream as much as
possible. Inlet and outlet elevations and stream bed elevations should be indicated.
Any widening of the stream must be shown with elevations.
The extent of and plan details for all dissipation or grade control devices should be shown
with pertinent elevations.
For shorter culvert sections, such as for road crossings, a longitudinal cross section that
shows the stream bed invert at the inlet and outlet, the existing stream bank elevations
and the invert of the inlet and outlet of the pipe(s) must be provided.
For shorter culvert sections, such as for road crossings, a vertical cross section must be
provided that shows the stream cross section at the inlet and outlet overlain with the
culvert and fill cross section.
For bottomless culverts or other spans, a vertical cross section should be provided that
shows the minimum distance from each span to each stream bank, the stream cross
section, the height of the span above the stream and the minimum distance from the
edge of each footer to each stream bank.
For bottomless culverts or other spans, a plan view must be provided that shows the
location of the spans and the stream banks.
For longer culverts or culverts that will pass beneath substantial impervious cover, it will
be necessary to provide adequate plan detail to show that discharge velocity/energy will
be adequately dissipated.

5
Aquatic life passage through culverts is typically achieved by placing the invert of the
culvert below the existing bed of the stream per the USACE or North Carolina Wildlife
Resource Commission guidelines. Other methods such as baffles may also be used.
Please be aware that such placement may require the use of grade/velocity control
measures up or down stream of culverts on steeper streams to prevent head-cuts or
stream bed erosion. The culvert placement relative to the stream bed can be indicated
on the longitudinal profile. Grade and velocity control measures must be indicated on the
plan view and typical designs should be provided.
Multiple culverts, wide culverts or sectioned box culverts typically require the use of sills,
off-setting or other means to match the cross section of the existing stream (in order to
maintain stream stability and provide aquatic life passage). A vertical cross section of the
culverts should be shown overlain with the up and downstream stream cross section
including the stream flood-prone area.
Impacts associated with dam construction must indicate and enumerate all fill associated
with the dam foot print, spillway and any bank stream bank stabilization. The length of
stream impounded must also be indicated and enumerated.
Stream Relocations:
Stream relocations must be conducted as specified in General Certification numbers
3402 and 3404 (available on the Wetlands Unit web site). Stream relocation plans must
include:
Morphological measurements (see Appendix B of the Internal Technical Guide for Stream
Work in North Carolina available on the Wetlands Unit web site) -not all of the
measurements are applicable in every instance.
Typical stream cross sections - Typically, a riffle cross section and a pool cross section
that includes the entire flood prone area. The bankfull and flood prove area elevations
should be indicated. Similarly, a riffle cross section of the reference stream(s) should be
provided.
Plan view -Provide scaled plans that show the location of the proposed (preferably with
stationing) and the existing stream. In most instances, the bankfull contours and flood
prone area contours, in stream structures, bank revetments/stabilization, channel plugs,
planting plan, vegetation conditions, stormwater outlets, grade controls, bridges, culverts,
sewer lines, roads, fencing, and easement lines should also be provided.
Longitudinal Stream Profile - A scaled profile that indicates the thalweg, bankfull, and top
of bank elevations should be provided for the design and reference streams. In many
cases, it will also be necessary to show the existing land elevations for the design
stream.
Planting Plan - A planting and/or vegetation management plan should also be provided
that makes use of appropriate native vegetation. The plan should indicate the extent,
density, and species of plants to be provided.
In-stream structure, bank revetment/stabilization, and stormwater outlet typicals -
Detailed, typical plans should be provided for all in stream structures, bank revetments or
stabilization, and stormwater outlets. The typicals should include materials and
specifications as well as relative lengths, positions, and angles.
Sediment transport analysis - A sediment transport analysis should be provided based
on the current, relevant, accepted practices. The sediment transport analysis should be
relevant to the stream bed load type and should predict bed load transport equilibrium.
Permanent conservation easement or similar means of protection must also be provided.

Other Information:
1. The project should always be referred to by this name in all correspondence as welt
as the DWO # once it is provided.
2. This only applies to DOT projects, which are not expected to utilize the Express
Review Program.
3. This should be the size of the project as identified by the USACE for 404 Permits or
by the Division of Water Quality for Buffer Approvals and Isolated Wetland Permits.
4. Please provide the name (as depicted on the USGS topographic map and DWO
Stream Classification Lists) of the nearest water body(ies) to which your project is a
tributary to (e.g. "Neuse River (Falls Lake below normal pool elevationJ'). (Do not
simple state "stream", "river", "ocean", "sound" or "lake".) Please provide the "stream
index number" of the named water body or water body section (e.g. "27-(1)"). Also,
please provide the full water quality classification (e.g. "WS-IV NSW CA") of the water
body. This information can be obtained from the DWO web site
http://h2o.enr.state.nc.us/bims/Reports/reportsW B.html.
5. Please state which river basin and sub-basin that your project is in (e.g. "Neuse River
Basin, NEU01"). This information can be obtained from the DWQ web site
http://h2o.enr.state.nc.us/bims/Reports/reportsW B.html.
6. Conditions should also be indicated on the existing site plan where applicable.
Photos (including aerial photos) can be helpful in describing the existing conditions.
7. You must provide an attachment that explicitly describes what the proposed project
will entail from the planning stage to final construction.
8. This can be a simple explanation, but it is critically important because the purpose
dictates how the no practical alternatives are reviewed.
SECTION IV -PR IOR PROJECT HISTORY
Please include copies of all 401 Water Quality Certifications, Isolated Wetland
Permits, Buffer Approvals, USACE Permits, CAMA Permits for the site as well as a
copy of the final approved, site plan.
SECTION V -FUTURE PROJECT PLANS
For projects utilizing the express review process, all impacts both present and
potential future must be indicated. For instance, the location or configuration of
platted lots sometimes suggests that future impacts will be necessary to build,
access, or otherwise develop such lots. Failure to account for such potential impacts
could delay or disqualify a project from the rapid review process. If you believe that
the lot can be developed without impacts, but you anticipate that your assertion may
be questioned, it is recommended that you provide a potential building foot print
and/or grading plan to show that future impacts could be avoided.
SECTION VI -PROPOSED IMPACTS TO WATER OF THE US
It is recommended that the individual impacts be described if there are special things
to note about the impacts. Typically the most important thing is to have detailed
accurate site plans as described above. Please make sure they are clearly labeled.
Please include afl proposed temporary impacts.

^ Also, a current, signed delineation map from the USACE should be provided (if
available) and a map locating the stream origins signed by the appropriate DWQ
Staff must be provided if applicable.
2. Each impact to a wetland must be clearly labeled and identified on the site plan. The
type of impact must be clearly stated. If the impact is temporary, a specific plan must
be described or shown as to how the wetland will be restored. Keep in mind that the
USACE delineates some features as wetlands that DWO calls streams. Please list
any impacts in this table that DWO would identify as a stream. If there is any doubt,
it is recommended that the impacts be listed as streams. Please follow current DWQ
policy with respect to whether a stream is perennial or not. It is recommended that
you assume that a stream is perennial (unless you are positive that it is not) so if
mitigation is required then the appropriate amount of mitigation would be anticipated
or requested from the EEP or private bank. If the EEP or private bank has pre-
approved too short of an amount of stream or if inadequate mitigation is proposed,
then that situation will result in delays.
Sometimes it is difficult to determine whether a feature is a modified natural channel
or a ditch, especially in the eastern part of the State. Soils, drainage features,
topography, and similar factors, all are important for making that determination.
Other items to address not specifically requested in the application include
downstream sediment starvation, thermal pollution, low flow releases from dams, and
aquatic life passage. Other important considerations are buffer reestablishment or
mitigation around ponds on buffered streams. The site plan should include the
precise elevation contour of the normal pool as well as the dam foot-print. Mitigation
is required for wetland flooding of an acre or greater and for stream fill (if over the
150 foot threshold) under the dam foot-print and any outlet stabilization.
SECTION VII -AVOIDANCE AND MINIMIZATION
Avoidance and minimization are critical aspects of an application particularly if you desire the application
to be processed expeditiously. The following is a check-list of avoidance and minimization questions that
DWO Staff often look for in applications.
Are there any stream crossings at angles less than 75° or greater than 105°?
Are there any stream crossings that cross two streams above or at the confluence of those
streams?
Are there any stream, wetland, water, and/or buffer impacts other than perpendicular road
crossing near the edges of the property?
Can the stream be relocated as a natural channel design as opposed to culverted or
otherwise filled?
Is any single stream crossed more than once?
Can property access routes be moved or reduced to avoid stream, wetland, water, and
buffer impacts?
Can a building, parking lot, etc. be realigned to avoid impacts?
Can the site layout be reconfigured to avoid impacts?
Can headwalls or steeper side slopes be used to avoid/minimize impacts?
:-~ Can a retaining wall be used to avoid/minimize impacts?

Can cul de sacs be used in place of a crossing?
Can lots be reshaped or have shared driveways to avoid impacts?
If based solely on the practicable physical possibility, the answer is "yes" to any of the above questions
then you must have to provide substantial and convincing justification as to why the impacts are
necessary. If the impacts are required by a local government or other agency, the claim must be
supported with appropriate written documentation from the local government or other agency. Most
projects typically involve the need to justify avoidance and minimization. If this information is not readily
available, then the express review process may not be the appropriate venue to use. Providing
alternative plans (such as plans that avoid the impact, minimize the impact and the preferred plan, similar
to those used in environmental assessments) and explanations as to why the preferred plan is needed
and why the alternative plans won't work are many times helpful in the no practical alternatives review.
SECTION VIII -MITIGATION
Mitigation for the Express Review Program, final mitigation plans must be presented up front. The final
plans (except for plans that propose payment into the Ecosystem Enhancement Program (EEP), Riparian
Buffer Restoration Fund, private mitigation banks, or similar banking instruments) must contain detailed
plans, specifications, calculations and other supporting data that show that the appropriate mitigation will
be achieved at the ratios required. The design plans must be developed to at least the "90%" level.
Monitoring plans must be final and specific. Any means of permanent protection, such as a permanent
conservation easement must be provided. If you elect to use the EEP or a private mitigation bank, it is
recommended that you request the maximum possible mitigation amount that DWQ may require so that
you will not have to get further approval from them on short notice. The EEP and private banks are not
part of the expedited review process and cannot be expected to meet any such deadlines. There will be
no conditional expedited approvals that require final plans at a later date. It is not recommended that
innovative mitigation techniques or greater than 10% preservation be requested as part of an expedited
process.
SECTION IX
If your project requires the preparation of an environmental document under NEPA or SEPA and an
approval letter has not been issued by the State Clearinghouse, then you cannot apply under the
expedited review process. I t is your responsibility to find out if such documentation is required.
SECTION X
There are many aspects of the Buffer Rules that must be addressed in every application, if applicable.
The first and most important thing to keep in mind is that allowable activities that require written Approval
from DWQ triggers a review of the entire project for compliance with the Buffer Rules.
Diffuse Flow &Stormwater Management:
The most common issues that arise involve the requirement for diffuse flow of stormwater
through riparian buffers. Basically one of three things must be indicated in regards to all
"new" stormwater that is collected and subsequently discharged. First, provisions for
diffuse flow through the protected buffer must be made. This usually involves the use of
level spreading devices designed to the latest DWQ guidance on level spreader design,
which is available on our web site. Please keep in mind that it does not matter how far a
discharge point is from a buffer. The stormwater must be flowing in a diffuse manner at
whatever point it eventually reaches the buffer. If the stormwater will not be flowing in a
diffuse manner through the protected buffer at the point it reaches the buffer, then one of
the following options may be allowed:
You may provide a nitrogen removing measure such as a forested filter strip,
grassed swale, stormwater wetland, etc. The measure employed should be
designed according to the NC DENR Stormwater Best Management Practices
Manual or other DWQ Guidance available at http:

9
//h2o.ehnr.state.nc.us/ncwetlands/mitresto.html. After the nitrogen is treated, the
stormwater can be directly conveyed through the buffer with written DWQ approval.
You may discharge the stormwater to an existing man-made conveyance that
currently conveys stormwater through the protected buffer (assuming the
conveyance was not constructed in violation of the Rules) as long as that
conveyance does not need to be altered to convey the flow. Please remember that
there are no other choices. The following checklist is intended to help insure that
your application will not be deemed incomplete as a result of improper stormwater
design.
stormwater Management (for Buffer Rules compliance only -Also, see Section XI):
All stormwater out-falls must be clearly shown and labeled on the site plan for projects in
Buffered watersheds. List each out-fall as labeled:
Option 1: Level spreading devices designed to the latest DWQ Guidance, and
devices that merely control velocity but do not provide diffuse flow such as rip rap
dissipators are not proposed. List each of these out-falls as labeled on the site
plan and provide a DWQ worksheet available at
http://h2o. eh n r.state. nc. us/ncwetlands/m itresto. htm I
Option 2: Nitrogen removing measures designed to DWQ Standards are
proposed for discharges for which diffuse flow through a protected Buffer cannot be
met. List each of these out-falls as labeled on the site plan and provide a DWQ
worksheet available at http://h2o.ehnr.state.nc.us/ncwetlands/mitresto.html:
Option 3: The stormwater will be discharged to an existing man-made (not
including modified natural channels) conveyance that carries the stormwater
through the Buffer. The conveyance was not constructed in violation of the Buffer
Rules. List each out-fall as labeled:
All stormwater out-fall must meet one of the options above. (Note: if you cannot check this
box your application will likely not be accepted into the express review process.)
Site Plans:
All applications on properties with DWQ protected buffers must clearly depict the buffers
and any impacts to the buffers on the site plans. The impact maps should clearly depict
both zones of the protected buffers and the proposed impact areas (provided in square
feet).
Surface Water & Buffer Delineations:
Any surface waters subject to DWQ protected buffers must be field located and accurately
depicted on the site plans and impact maps. The width, dimensions and pattern of the
surface water must be delineated. The surface water location must not be taken simply
from a USGS map, soil survey or local municipality's map. The buffers must be measured
from the surface water as required within the applicable buffer protection rule (e.g., all
buffers along streams subject to the Neuse Buffer Rule must be measured from the "top-of-
bank" of the stream and not the centerline of the stream). All streams must be surveyed or
located by GPS and shown precisely on the site plans.
Impact Table:
Please provide additional impact tables that clearly state the area of impact for each
corresponding impact site.

10
Variances:
C Projects that require a Minor, Major and/or "General" Variance will not be eligible for the
use of the Express Review Program.
Mitigation:
As opposed to applications that are submitted under our regular process, final mitigation
plans must be presented upfront (see requirements for Section VIII above). The mitigation
plans must comply with the applicable buffer mitigation rule.
SECTION XI - STORMWATER
Please provide the following information in regards to potential stormwater requirements:
The total acreage of the site. (acres)
The total built-out impervious acreage (acres)
The total area that will be disturbed (acres)
If the total area exceeds 20% imperviousness, the development on the site is uniform in
density, and you claim that the total impervious area is less than 30%, you must provide a
complete, detailed breakdown of the assumed built-out conditions. The breakdown must
be detailed enough to show that all potential impervious areas are accounted for.
If there are concentrated areas of development such as multi-family, commercial, cluster,
club houses, etc. that exceed 30% imperviousness and the total imperviousness for the site
does not exceed 30%, a stormwater management plan will likely be required for those
areas that exceed 30% imperviousness.
stormwater management plans must be complete with a final design and an executed
Operation and Maintenance Agreement. There will be no conditional stormwater approvals
for the express review process that allow for approval of the final plans at a later date.
Worksheets must be provided that are available at
http://h2o.ehnr.state.nc.us/ncwetlands/mitresto.html.
SECTION XII -SEWAGE DISPOSAL
Response must be clear and detailed. Any disposal method that suggests further impacts
may be required other than those shown must be clearly addressed on the site plans.
SECTION XIII
Answering yes to either of these responses automatically precludes you from the express
review process.
SECTION XIV -SIGNATURE
The name, position and/or title of the applicant must be in type or long hand script here with
the signature. It should be the same person as described in Part II.
If you have any questions about these requirements, please email the Express Review Program at
401 [e-mail] and include your question and phone number and the appropriate staff will
respond as soon as possible.
