Dear Mr. Phillips,
Reference: AID: SAW-2023-00520 Twelve Oaks Stream Restoration NWP #27 PCN
The purpose of this letter is to submit a preconstruction notification for a Nationwide Permit #27 for a stream
restoration project on a UT to Little Branch within the Twelve Oaks subdivision in Holly Springs, NC.
The Twelve Oaks Stream Restoration project consists of restoration to an unnamed tributary to Little
Branch (Stream SA). Stream SA is a perennial stream that flows through the Twelve Oaks Golf Course to
the west through a residential area and eventually through a box culvert under Ivy Arbor Way. The stream
is exhibiting lateral and vertical channel migration causing extensive erosion which is introducing excess
sediment into the stream and threatening public and private infrastructure. A short retaining wall is present
along the left bank while a sanitary sewer line parallels stream SA on the right bank of the stream.
Stormwater drainage enters the stream within the project area via an outlet and ditch on the left bank near
the beginning of the project. A small number of mature trees are present but largely the riparian corridor is
made up of young successional vegetation including pines and red maple.
Streams and wetlands were delineated by others during excessive drought conditions in 2007 or 2008 as
part of the overall development of the Twelve Oaks subdivision. At that time, UT to Little Branch was
delineated as a linear wetland. Delineations in 2023 show that the stream (SA) exhibits clear perennial
stream features including defined bed and bank as well as a number of macrobenthic invertebrates (see
attached forms). Stream SA scored "Low" in habitat, hydrology and WQ metrics in an NCSAM assessment.
No wetlands were found within the project area.
The goal of this project is to provide functional uplift and greatly reduce excess sediment contribution to UT
to Little Branch (Stream SA) which is currently actively degrading and threatening surrounding
infrastructure. This project aims to restore riparian areas and restore the stream channel to avoid further
property damage. The goals of the project are to improve instream habitat, reduce stream bank erosion,
enhance native riparian vegetation, and restore the channel to protect surrounding infrastructure.

Re: PRIVATE DRAINAGE EASEMENT (NEAR LOT 918,137 ROSEROOT CT)
Issue Presented
The purpose of this Memorandum is to provide the Board of Directors with a legal opinion
regarding the Twelve Oaks Master Association's ("the Association") responsibility for
maintenance of the Variable Width Private Drainage Easement ("VWPDE") located near Lot 918,
137 Roseroot Court. Holly Springs as shown on the map book 2015, page 962 of the Wake County
Register of Deeds under the Amendment to Master Declaration of Covenants, Conditions,
Restrictions, Easements, Charges and Liens recorded at Book 17224, page 1462 of the Wake
County Register of Deeds ("the Declaration"). The central issue is whether the Association bears
responsibility for maintaining the VWPDE pursuant to the Declaration after erosion has caused
damage to the retaining wall built by the developer on Lot 918. The VWPDE also touches the rear
of Lot 919 on the map at 2015/962 and a VWPDE also extends down Lots 916 and terminating
between Lots 906 and 905at Common Area owned by the Association in fee simple.' The
Association has received two estimates — (1) Stantec Consulting Services, Inc.; and (2) McAdams.
The Stantec proposal references "a channel located between 133 and 137 Roseroot Court has
experienced migration of a head cut to within approximately 10 linear feet from a stormwater
outfall." The Stantec proposal is for work in or immediately adjacent to the VWPDE on Lot 918,
as well as, the "stormwater channel" between Lots 917 and 918.2
Summary
The Association is responsible for maintaining the Common Area pursuant to Article 1,
Section 12 of the Declaration which states, "[a]11 Common Area not maintained by a Sub -Association
(hereinafter defined) shall be maintained by the Master Association unless dedicated to public use and
accepted by a public agency, authority or utility or conveyed to another nonprofit entity formed for similar
purposes." Article 1, Section 12 of the Declaration defines Common Area as, "all real property and
improvements thereon owned in fee by the Association for the common use, enjoyment or benefit of some
1 Property identified as Lot 721 on Plat Map recorded at Map Book 2015, page 962, Wake County Register of Deeds,
and conveyed to the Association via non -warranty deed July 13, 2018 recorded at Book 17221, page 799, Wake
County Register of Deeds.
2 There is a 20' private drainage easement shown on the map recorded @ 2015/962 between these two Lots.
www.jordanPrice.com • Office 919-828-2501 • Fax [phone] • 1951 Clark Avenue • P.O. Box 10669 • Raleigh, NC 27605

or all of the Members or the Properties ... and (ii) all rights and easements of the Association in, on, under,
over and through any real property not owned in fee by the Association, together with all improvements on
such real property that are owned by the Association..."
Article 8, Section 1 of the Declaration reserves a "`drainage easement', or any similar
designation, and any combination of the foregoing on any recorded map or plat of any portion of
the Properties for the purpose of installing, operating, repairing and maintaining, as appropriate,
landscaping, irrigation system, entrance signage, fencing and Stormwater Measures in the
easement area." Article 8, Section 1 of the Declaration further reserves in favor of the Association
the right of ingress and egress to "maintain and correct drainage or surface water runoff in order
to maintain reasonable standards of health, safety and appearance"... including the right to "make
any gradings of the soil, or take any other similar action that it deems reasonably necessary or
appropriate."
Moreover, Article 6, Section 4 of the Declaration establishes the Association's
responsibility for maintaining the VWPDE by explicitly stating "the Association shall maintain
the Stormwater Control Measures as part of the Common Expenses. As used in the immediately
preceding sentence, the word "maintain" includes provision for maintenance of, which may include
financial contributions toward maintenance of Stormwater Control Measures located on and/or
shared with other properties not subject to the Declaration." Storm Water Control measures is
defined as including storm -water drainage easements in Article I, Section 37 of the Declaration.
However, Article 6, Section 4 of the Declaration does indicate that owners are solely responsible
for maintenance for control measures that are used exclusively with their lot.
Here, the VWPDE would fall under the easement reservation of Article 8, Section 1 of the
Declaration for the repair and maintenance of Stormwater Measures. The issues associated with
the erosion of the retaining wall would be within the rights of the Association to maintain and
correct the drainage and surface water runoff to prevent further damage to the properties subject
to the Declaration. Further, the Plat Map recorded at map book 2015, page 962 shows that the
VWPDE affects multiple lots in the subdivision and would fall squarely within the "Common
Expense" requirements of Article 6, Section 4 of the Declaration. The VWPDE is shown extending
in a southerly direction across the rear portions of Lots 918,917,916,915,914,913,912,911,910,909
and terminating at the Common Area owned by the Association on Morning Oaks Drive. Any
required maintenance of the VWPDE, including financial contributions, would be a Common
Expense that the Association would bear responsibility for.
In sum, the Association is responsible for maintaining the VWPDE pursuant to the
Declaration, the Plat Map recorded at map book 2015, page 962 of the Wake County Register of
Deeds.Our presumption here is that the proposals from Stanpac and McAdams contemplate work
within such VWPDE. If so, then it would be the Association's responsibility. If not, then we can
reevaluate responsibility. You might show both Stanpac and McAdams the attached recorded map
and ask whether the scope of this work is all within VWPDE shown on this recorded plat.

IPaC resource list
This report is an automatically generated list of species and other resources such as critical
habitat (collectively referred to as trust resources) under the U.S. Fish and Wildlife Service's
(USFWS) jurisdiction that are known or expected to be on or near the project area referenced
below. The list may also include trust resources that occur outside of the project area, but
that could potentially be directly or indirectly affected by activities in the project area.
However, determining the likelihood and extent of effects a project may have on trust
resources typically requires gathering additional site -specific (e.g., vegetation/species
surveys) and project -specific (e.g., magnitude and timing of proposed activities) information.
Below is a summary of the project information you provided and contact information for the
USFWS office(s) with jurisdiction in the defined project area. Please read the introduction to
each section that follows (Endangered Species, Migratory Birds, USFWS Facilities, and NWI
Wetlands) for additional information applicable to the trust resources addressed in that
section.

Endangered species
This resource list is for informational purposes only and does not constitute an analysis
of project level impacts.
The primary information used to generate this list is the known or expected range of each
species. Additional areas of influence (AOI) for species are also considered. An AOI includes
areas outside of the species range if the species could be indirectly affected by activities in
that area (e.g., placing a dam upstream of a fish population even if that fish does not occur at
the dam site, may indirectly impact the species by reducing or eliminating water flow
downstream). Because species can move, and site conditions can change, the species on this
list are not guaranteed to be found on or near the project area. To fully determine any
potential effects to species, additional site -specific and project -specific information is often
required. 4 T>
Section 7 of the Endangered Species Act requires Federal agencies to "request of the
Secretary information whether any species which is listed or proposed to be listed may be
present in the area of such proposed action" for any project that is conducted, permitted,
funded, or licensed by any Federal agency. A letter from the local office and a species list
which fulfills this requirement can only be obtained by requesting an official species list from
either the Regulatory Review section in IPaC (see directions below) or from the local field
office directly.
For project evaluations that require USFWS concurrence/review, please return to the IPaC
website and request an official species list by doing the following:
1. Draw the project location and click CONTINUE.
2. Click DEFINE PROJECT.
3. Log in (if directed to do so).
4. Provide a name and description for your project.
5. Click REQUEST SPECIES LIST.
Listed speciesl and their critical habitats are managed by the Ecological Services Program of
the U.S. Fish and Wildlife Service (USFWS) and the fisheries division of the National Oceanic
and Atmospheric Administration (NOAA Fisheries).
Species and critical habitats under the sole responsibility of NOAA Fisheries are not shown
on this list. Please contact NOAA Fisheries for species under their jurisdiction.
1. Species listed under the Endangered Species Act are threatened or endangered; IPaC also
shows species that are candidates, or proposed, for listing. See the listing status page for
more information. IPaC only shows species that are regulated by USFWS (see FAQ).

Probability of Presence Summary
The graphs below provide our best understanding of when birds of concern are most likely
to be present in your project area. This information can be used to tailor and schedule your
project activities to avoid or minimize impacts to birds. Please make sure you read and
understand the FAQ "Proper Interpretation and Use of Your Migratory Bird Report" before
using or attempting to interpret this report.
Probability of Presence (■)
Each green bar represents the bird's relative probability of presence in the 10km grid cell(s)
your project overlaps during a particular week of the year. (A year is represented as 12 4-
week months.) A taller bar indicates a higher probability of species presence. The survey
effort (see below) can be used to establish a level of confidence in the presence score. One
can have higher confidence in the presence score if the corresponding survey effort is also
high.
How is the probability of presence score calculated? The calculation is done in three steps:
1. The probability of presence for each week is calculated as the number of survey events in
the week where the species was detected divided by the total number of survey events
for that week. For example, if in week 12 there were 20 survey events and the Spotted
Towhee was found in 5 of them, the probability of presence of the Spotted Towhee in
week 12 is 0.25.
2. To properly present the pattern of presence across the year, the relative probability of
presence is calculated. This is the probability of presence divided by the maximum
probability of presence across all weeks. For example, imagine the probability of
presence in week 20 for the Spotted Towhee is 0.05, and that the probability of presence
at week 12 (0.25) is the maximum of any week of the year. The relative probability of
presence on week 12 is 0.25/0.25 = 1; at week 20 it is 0.05/0.25 = 0.2.
3. The relative probability of presence calculated in the previous step undergoes a statistical
conversion so that all possible values fall between 0 and 10, inclusive. This is the
probability of presence score.
To see a bar's probability of presence score, simply hover your mouse cursor over the bar.
Breeding Season( )
Yellow bars denote a very liberal estimate of the time -frame inside which the bird breeds
across its entire range. If there are no yellow bars shown for a bird, it does not breed in your
project area.
Survey Effort ( )
Vertical black lines superimposed on probability of presence bars indicate the number of
surveys performed for that species in the 10km grid cell(s) your project area overlaps. The
number of surveys is expressed as a range, for example, 33 to 64 surveys.

To see a bar's survey effort range, simply hover your mouse cursor over the bar.
No Data ( )
A week is marked as having no data if there were no survey events for that week.
Survey Timeframe
Surveys from only the last 10 years are used in order to ensure delivery of currently relevant
information. The exception to this is areas off the Atlantic coast, where bird returns are
based on all years of available data, since data in these areas is currently much more sparse.

Tell me more about conservation measures I can implement to avoid or minimize impacts to migratory
birds.
Nationwide Conservation Measures describes measures that can help avoid and minimize impacts to all
birds at any location year round. Implementation of these measures is particularly important when birds
are most likely to occur in the project area. When birds may be breeding in the area, identifying the
locations of any active nests and avoiding their destruction is a very helpful impact minimization measure.
To see when birds are most likely to occur and be breeding in your project area, view the Probability of
Presence Summary. Additional measures or permits may be advisable depending on the type of activity
you are conducting and the type of infrastructure or bird species present on your project site.

What does IPaC use to generate the list of migratory birds that potentially occur in my specified
location?
The Migratory Bird Resource List is comprised of USFWS Birds of Conservation Concern (BCC), and other
species that may warrant special attention in your project location.
The migratory bird list generated for your project is derived from data provided by the Avian Knowledge
Network (AKN). The AKN data is based on a growing collection of survey, banding, and citizen science
datasets and is queried and filtered to return a list of those birds reported as occurring in the 10km grid
cell(s) which your project intersects, and that have been identified as warranting special attention because
they are a BCC species in that area, an eagle (Eagle Act requirements may apply), or a species that has a
particular vulnerability to offshore activities or development.
Again, the Migratory Bird Resource list includes only a subset of birds that may occur in your project area.
It is not representative of all birds that may occur in your project area. To get a list of all birds potentially
present in your project area, please visit the Rapid Avian Information Locator (RAIL) Tool. *4
What does IPaC use to generate the probability of presence graphs for the migratory birds potentially
occurring in my specified location?
The probability of presence graphs associated with your migratory bird list are based on data provided by
the Avian Knowledge Network (AKN),. This data is derived from a growing collection of survey., banding, and
citizen science datasets. AMhL
Probability of presence data is continuously being updated as new and better information becomes
available. To learn more about how the probability of presence graphs are produced and how to interpret
them, go the Probability of Presence Summary and then click on the "Tell me about these graphs" link.
How do I know if a bird is breeding, wintering or migrating in my area?
To see what part of a particular bird's range your project area falls within (i.e. breeding, wintering,
migrating or year-round), you may query your location using the RAIL Tool and look at the range maps
provided for birds in your area at the bottom of the profiles provided for each bird in your results. If a bird
on your migratory bird species list has a breeding season associated with it, if that bird does occur in your
project area, there may be nests present at some point within the timeframe specified. If "Breeds
elsewhere" is indicated, then the bird likely does not breed in your project area.
What are the levels of concern for migratory birds?
Migratory birds delivered through IPaC fall into the following distinct categories of concern:
1. "BCC Rangewide" birds are Birds of Conservation Concern (BCC) that are of concern throughout their
range anywhere within the USA (including Hawaii, the Pacific Islands, Puerto Rico, and the Virgin
Islands);
2. "BCC - BCR" birds are BCCs that are of concern only in particular Bird Conservation Regions (BCRs) in
the continental USA; and
3. "Non -BCC - Vulnerable" birds are not BCC species in your project area, but appear on your list either
because of the Eagle Act requirements (for eagles) or (for non -eagles) potential susceptibilities in
offshore areas from certain types of development or activities (e.g. offshore energy development or
longline fishing).

IPaC: Explore Location resources
Although it is important to try to avoid and minimize impacts to all birds, efforts should be made, in
particular, to avoid and minimize impacts to the birds on this list, especially eagles and BCC species of
rangewide concern. For more information on conservation measures you can implement to help avoid and
minimize migratory bird impacts and requirements for eagles, please see the FAQs for these topics.
Details about birds that are potentially affected by offshore projects
For additional details about the relative occurrence and abundance of both individual bird species and
groups of bird species within your project area off the Atlantic Coast, please visit the Northeast Ocean Data
Portal. The Portal also offers data and information about other taxa besides birds that may be helpful to
you in your project review. Alternately, you may download the bird model results files underlying the portal
maps through the NOAA NCCOS Integrative Statistical Modeling and Predictive Mapping of Marine Bird
Distributions and Abundance on the Atlantic Outer Continental Shelf project webpage.
Bird tracking data can also provide additional details about occurrence and habitat use throughout the
year, including migration. Models relying on survey data may not include this information. For additional
information on marine bird tracking data, see the Diving Bird Study_ and the nanotag studies or contact
Caleb Spiegel or Pam Loring. �. IL i j
What if I have eagles on my list?
If your project has the potential to disturb or kill eagles, you may need to obtain p rmit to avoid violating
the Eagle Act should such impacts occur. V
Proper Interpretation and Use of Your Migratory Bird Report
The migratory bird list generated is not a list of all birds in your project area, only a subset of birds of
priority concern. To learn more about how your list is generated, and see options for identifying what
other birds may be in your project area, please see the FAQ "What does IPaC use to generate the migratory
birds potentially occurring in my specified location". Please be aware this report provides the "probability
of presence" of birds within the 10 km grid cell(s) that overlap your project; not your exact project
footprint. On the graphs provided, please also look carefully at the survey effort (indicated by the black
vertical bar) and for the existence of the "no data" indicator (a red horizontal bar). A high survey effort is
the key component. If the survey effort is high, then the probability of presence score can be viewed as
more dependable. In contrast, a low survey effort bar or no data bar means a lack of data and, therefore, a
lack of certainty about presence of the species. This list is not perfect; it is simply a starting point for
identifying what birds of concern have the potential to be in your project area, when they might be there,
and if they might be breeding (which means nests might be present). The list helps you know what to look
for to confirm presence, and helps guide you in knowing when to implement conservation measures to
avoid or minimize potential impacts from your project activities, should presence be confirmed. To learn
more about conservation measures, visit the FAQ "Tell me about conservation measures I can implement
to avoid or minimize impacts to migratory birds" at the bottom of your migratory bird trust resources
page.

Wetlands in the National Wetlands Inventory
(NWI)
Impacts to NWI wetlands and other aquatic habitats may be subject to regulation under
Section 404 of the Clean Water Act, or other State/Federal statutes.
For more information please contact the Regulatory Program of the local U.S. Army Corps of
Engi e rs D' tri
Wetland information is not available at this time
This can happen when the National Wetlands Inventory (NWI) map service is unavailable, or
for very large projects that intersect many wetland areas. Try again, or visit the NWI map to
view wetlands at this location.
Data limitations
The Service's objective of mapping wetlands and deepwater habitats is to produce reconnaissance level
information on the location, type and size of these resources. The maps are prepared from the analysis of
high altitude imagery. Wetlands are identified based on vegetation, visible hydrology and geography. A
margin of error is inherent in the use of imagery; thus, detailed on -the -ground inspection of any particular
site may result in revision of the wetland boundaries or classification established through image analysis.
https://ipac.ecosphere.fws.gov/location/54WU5GI UZVFKZK4ASB2ZT7AU R4/resources 11 /12

1 /3/23, 1:29 PM
IPaC: Explore Location resources
The accuracy of image interpretation depends on the quality of the imagery, the experience of the image
analysts, the amount and quality of the collateral data and the amount of ground truth verification work
conducted. Metadata should be consulted to determine the date of the source imagery used and any
mapping problems.
Wetlands or other mapped features may have changed since the date of the imagery or field work. There
may be occasional differences in polygon boundaries or classifications between the information depicted
on the map and the actual conditions on site.
Data exclusions
Certain wetland habitats are excluded from the National mapping program because of the limitations of
aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or
submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and
nearshore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also
been excluded from the inventory. These habitats, because of their depth, go undetected by aerial '14
imagery.
Data precautions
Federal, state, and local regulatory agencies with jurisdiction over wetlands may define and describe
wetlands in a different manner than that used in this inventory. There is no attempt, in either the design or
products of this inventory, to define the limits of proprietary jurisdiction of any Federal, state, or local
government or to establish the geographical scope of the regulatory programs of government agencies.
Persons intending to engage in activities involving modifications within or adjacent to wetland areas should
seek the advice of appropriate Federal, state, or local agencies concerning specified agency regulatory
programs and proprietary jurisdictions that may affect such activities.

Dear Amber Coleman.
D_ Reid Wilson, Secretary
Misty Buchanan
Deputy Director, Natural Heritage Program
NCNHDE-21269
The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide
information about natural heritage resources for the project referenced above.
Based on the project area mapped with your request, a query of the NCNHP database indicates that
there are no records for rare species, important natural communities, natural areas, and/or
conservation/managed areas within the proposed project boundary. Please note that although there
may be no documentation of natural heritage elements within the project boundary, it does not
imply or confirm their absence, the area may not have been surveyed. The results of this query
should not be substituted for field surveys where suitable habitat exists. In the event that rare
species are found within the project area, please contact the NCNHP so that we may update our
records.
The attached `Potential Occurrences' table summarizes rare species and natural communities that
have been documented within a one -mile radius of the property boundary. The proximity of these
records suggests that these natural heritage elements may potentially be present in the project area
if suitable habitat exists. Tables of natural areas and conservation/managed areas within a one -mile
radius of the project area, if any, are also included in this report.
If a Federally -listed species is found within the project area or is indicated within a one -mile radius of
the project area, the NCNHP recommends contacting the US Fish and Wildlife Service (USFWS) for
guidance. Contact information for USFWS offices in North Carolina is found here.
httl2s //www.fws.gov/offices/Directory/ListOffices.cfm?statecode=37.
Please note that natural heritage element data are maintained for the purposes of conservation
planning, project review, and scientific research, and are not intended for use as the primary criteria
for regulatory decisions. Information provided by the NCNHP database may not be published
without prior written notification to the NCNHP, and the NCNHP must be credited as an information
source in these publications. Maps of NCNHP data may not be redistributed without permission.
The NC Natural Heritage Program may follow this letter with additional correspondence if a
Dedicated Nature Preserve, Registered Heritage Area, Land and Water Fund easement, or Federally -
listed species are documented near the project area.
If you have questions regarding the information provided in this letter or need additional assistance,
please contact Rodney A. Butler at rod ney.butlerLncdcr.gov or 919-707-8603.
Sincerely,
NC Natural Heritage Program

Note: After the permanent cessation of construction activities, any areas with temporary
ground stabilization shall be converted to permanent ground stabilization as soon as
practicable but in no case longer than 90 calendar days after the last land disturbing
activity. Temporary ground stabilization shall be maintained in a manner to render the
surface stable against accelerated erosion until permanent ground stabilization is achieved.
GROUND STABILIZATION SPECIFICATION
Stabilize the ground sufficiently so that rain will not dislodge the soil. Use one of the
techniques in the table below:
Temporary Stabilization
Permanent Stabilization
• Temporary grass seed covered with straw or
• Permanent grass seed covered with straw or
other mulches and tackifiers
other mulches and tackifiers
• Hydroseeding
• Geotextile fabrics such as permanent soil
• Rolled erosion control products with or
reinforcement matting
without temporary grass seed
• Hydroseeding
• Appropriately applied straw or other mulch
• Shrubs or other permanent plantings covered
• Plastic sheeting
with mulch
• Uniform and evenly distributed ground cover
sufficient to restrain erosion
• Structural methods such as concrete, asphalt or
retaining walls
• Rolled erosion control products with grass seed
POLYACRYLAMIDES (PAMS) AND FLOCCULANTS
1. Select flocculants that are appropriate for the soils being exposed during
construction, selecting from the NC DWR List of Approved PAMS/Flocculants.
2. Apply flocculants at or before the inlets to Erosion and Sediment Control Measures.
3. Apply flocculants at the concentrations specified in the NC DWR List of Approved
PAMS/Flocculants and in accordance with the manufacturer's instructions.
4. Provide ponding area for containment of treated Stormwater before discharging
offsite.
5. Store flocculants in leak -proof containers that are kept under storm -resistant cover
or surrounded by secondary containment structures.
QUIPMENT AND VEHICLE MAINTENANCE
1. Maintain vehicles and equipment to prevent discharge of fluids.
2. Provide drip pans under any stored equipment.
3. Identify leaks and repair as soon as feasible, or remove leaking equipment from the
project.
4. Collect all spent fluids, store in separate containers and properly dispose as
hazardous waste (recycle when possible).
5. Remove leaking vehicles and construction equipment from service until the problem
has been corrected.
6. Bring used fuels, lubricants, coolants, hydraulic fluids and other petroleum products
to a recycling or disposal center that handles these materials.
LITTER, BUILDING MATERIAL AND LAND CLEARING WASTE
1. Never bury or burn waste. Place litter and debris in approved waste containers.
2. Provide a sufficient number and size of waste containers (e.g dumpster, trash
receptacle) on site to contain construction and domestic wastes.
3. Locate waste containers at least 50 feet away from storm drain inlets and surface
waters unless no other alternatives are reasonably available.
4. Locate waste containers on areas that do not receive substantial amounts of runoff
from upland areas and does not drain directly to a storm drain, stream or wetland.
5. Cover waste containers at the end of each workday and before storm events or
provide secondary containment. Repair or replace damaged waste containers.
6. Anchor all lightweight items in waste containers during times of high winds.
7. Empty waste containers as needed to prevent overflow. Clean up immediately if
containers overflow.
S. Dispose waste off -site at an approved disposal facility.
9. On business days, clean up and dispose of waste in designated waste containers.
PAINT AND OTHER LIQUID WASTE
1. Do not dump paint and other liquid waste into storm drains, streams or wetlands.
2. Locate paint washouts at least 50 feet away from storm drain inlets and surface
waters unless no other alternatives are reasonably available.
3. Contain liquid wastes in a controlled area.
4. Containment must be labeled, sized and placed appropriately for the needs of site.
5. Prevent the discharge of soaps, solvents, detergents and other liquid wastes from
construction sites.
PORTABLE TOILETS
1. Install portable toilets on level ground, at least 50 feet away from storm drains,
streams or wetlands unless there is no alternative reasonably available. If 50 foot
offset is not attainable, provide relocation of portable toilet behind silt fence or place
on a gravel pad and surround with sand bags.
2. Provide staking or anchoring of portable toilets during periods of high winds or in high
foot traffic areas.
3. Monitor portable toilets for leaking and properly dispose of any leaked material.
Utilize a licensed sanitary waste hauler to remove leaking portable toilets and replace
with properly operating unit.
EARTHEN STOCKPILE MANAGEMENT
1. Show stockpile locations on plans. Locate earthen -material stockpile areas at least
50 feet away from storm drain inlets, sediment basins, perimeter sediment controls
and surface waters unless it can be shown no other alternatives are reasonably
available.
2. Protect stockpile with silt fence installed along toe of slope with a minimum offset of
five feet from the toe of stockpile.
3. Provide stable stone access point when feasible.
4. Stabilize stockpile within the timeframes provided on this sheet and in accordance
with the approved plan and any additional requirements. Soil stabilization is defined
as vegetative, physical or chemical coverage techniques that will restrain accelerated
erosion on disturbed soils for temporary or permanent control needs.

ABOVE GRADE WASHOUT STRUCTURE
1. Do not discharge concrete or cement slurry from the site.
2. Dispose of, or recycle settled, hardened concrete residue in accordance with local
and state solid waste regulations and at an approved facility.
3. Manage washout from mortar mixers in accordance with the above item and in
addition place the mixer and associated materials on impervious barrier and within
lot perimeter silt fence.
4. Install temporary concrete washouts per local requirements, where applicable. If an
alternate method or product is to be used, contact your approval authority for
review and approval. If local standard details are not available, use one of the two
types of temporary concrete washouts provided on this detail.
5. Do not use concrete washouts for dewatering or storing defective curb or sidewalk
sections. Stormwater accumulated within the washout may not be pumped into or
discharged to the storm drain system or receiving surface waters. Liquid waste must
be pumped out and removed from project.
6. Locate washouts at least 50 feet from storm drain inlets and surface waters unless it
can be shown that no other alternatives are reasonably available. At a minimum,
install protection of storm drain inlet(s) closest to the washout which could receive
spills or overflow.
7. Locate washouts in an easily accessible area, on level ground and install a stone
entrance pad in front of the washout. Additional controls may be required by the
approving authority.
8. Install at least one sign directing concrete trucks to the washout within the project
limits. Post signage on the washout itself to identify this location.
9. Remove leavings from the washout when at approximately 75% capacity to limit
overflow events. Replace the tarp, sand bags or other temporary structural
components when no longer functional. When utilizing alternative or proprietary
products, follow manufacturer's instructions.
10. At the completion of the concrete work, remove remaining leavings and dispose of
in an approved disposal facility. Fill pit, if applicable, and stabilize any disturbance
