Bedford Hills Subdivision

Dear Mr. Bailey & Ms. Homewood,
On behalf of our client and the applicant, Green Level Group, LLC, Summit Design and
Engineering Services is providing to you responses to comments from your review on
January 28, 2017 following our submittal of the PCN and plans on January 10, 2017.
Summit Design and Engineering Services will be more than happy to address and provide
any clarification needed on the attached responses and looks forward to discussing these
matters with you further.
Sincerely,
SUMMIT DESIGN AND ENGINEERING SERVICES
Chris Oliver, E.I.
Land Development Dept.

Comments Provided by Sue Homewood on January 17, 2017
David Bailey and I measured the existing crossing impact as 75 feet. That was measured
as a straight line from end of pipe to end of pipe and streams typically have some
sinuosity, so we would expect the PCN to list the impacts as something greater than 75
feet for the crossing at Pillow Lane.
Per email correspondence with David Bailey on 2/27/17, this comment may be
disregarded.
2. It is my understanding that the Town has already approved the stormwater management
plan. Please correct section E of the PCN form accordingly.
Section E of the PCN has been revised to include the following statement:
"The Town of Green Level reviewed and approved the Stormwater Management Plan for
Phase I of this project which includes the analysis of the proposed storm sewer network
for the 2-, 10-, and 25 yr storm events as well as the Wet Detention Pond BMP, which
was designed to control and treat runoff from the first inch of rainfall.
A Stormwater Management plan will be submitted to the Town of Green Level for Phase
II of this project. "
3. I think it will be necessary to provide a little more clarity/detail regarding why the
existing culvert location (even though it would require upgrading) cannot be used for the
southern crossing location.
The placement of the southern crossing allows much of Phase II to be served by gravity
sewer to the pump station just on the other side of the stream that serves Phase I.
Additionally, the existing culvert location cannot be used for the proposed crossing
because of subdivision layout and stormwater constraints to control and treat runoff
while avoiding impacts to existing wetlands on the site. This info has been added to the
PCN accordingly.
Comments Provided by David Bailey on January 18, 2017
I reiterate the 1 st and 3rd of Sue Homewood's (NCDWR) comments sent via email
1/17/2017, regarding the Crossing 1 stream impact length and the practicability of using
the footprint of the existing forestry road crossing location for at least a portion of the
footprint for proposed Crossing 2.
Per email correspondence with David Bailey on 2/27/17, the comment regarding the
Crossing 1 stream impact length may be disregarded.
Please see response to Comment #3 above.
2. If it is clearly explained why it is not practicable to use the existing forestry road crossing
location for at least a portion of the footprint for proposed Crossing 2, please include a
brief narrative of plans/methodology to remove the existing forestry road crossing,
including the proposed post-removal state of the stream channel in this location; note that
this was discussed during our pre -application phone conversation in December 2016.
The existing 24 "pipe will be removed with minimal land disturbance and with no heavy
equipment. The area will be minimally re -graded to match the surrounding area, and
once re -grading is complete, the disturbed area will be seeded and mulched with riparian

seed mix. If needed, temporary sand bags and adequately sized pumps will be used to
dam the stream during pipe removal and bypass flows around the work area. If base
flows exist in the pipe removal area silt fencing and a rock silt check downstream of the
work area will be provided for erosion and sediment control during pipe removal.
3. Please include rip rap impacts for Crossing 1 on the PCN and plans, as rip rap exists as
bank stabilization at the downstream end of Crossing 1 below the Ordinary high Water
Mark.
Rip rap impacts for Crossing 1 were added to the PCN and the plans. The rip rap
installed is temporary for erosion and sediment control and stabilization of the banks and
any unnecessary rip rap will be removed after construction of Phase I.
4. Please update plan sheet D -I to show a north arrow and graphic scale, in addition to the
text scale.
Plans updated.
5. Please update the cross-sections of Crossings 1 and 2:
a. Clearly show the existing stream bed as reference; -include the rip -rap
pad/plunge pool on the cross sections. Note that any rip rap in the channel should
be keyed into the stream bed rather than sitting on top of the stream bed. If the
latter is proposed, explain the justification and note that these impacts will be
considered mitigable and count towards the cumulative 150 linear foot mitigation
threshold; -Per Regional Conditions 3.6 of the NWP 29, culverts >48" in
diameter must be buried F below the bed of the stream. Ensure that the cross-
section shows that this requirement is being met for Crossing 2.
The existing stream bed identified and labeled.
The rip -rap apron is shown on the detail sheet and noted on the plan to be keyed
into the stream bed rather than sitting on top.
Both 54" culvert pipes will be buried ]ft. below the stream bed.
b. If maintaining the stream bank width downstream of Crossing 2 (Regional
Conditions 3.6) as required by is problematic, would it be practicable to design
the two culvert pipes such that one pipe is buried F to carry the normal low flow
and the 2nd pipe is set above the stream bed as a high flow culvert? If so, please
include these changes in the PCN and plans. If not, please explain why this is not
practicable.
The average stream bank width at Crossing 2 is 18 ft. The 54 " culvert pipes will
fat within the stream cross section to avoid widening at the inlets and outlets. The
pipes will be buried 1 ft. below the stream bed so as to maintain low flow depths
greater than or equal to the pre-existing condition allowing for safe aquatic
passage through the pipes.

2b. Is this an after -the -fact permit application?
❑X Yes ❑ No
2c. If you answered "yes" to one or both of the above questions, provide an explanation of the violation(s):
A permanent culvert was placed over approximately 75 feet of stream (impacts S -1-S-2). In addition to the culvert, a discharge of unauthorized fill
occurred in approximately 0.1 acres of wetlands due to development along Donelson way. The wetland impacts will be resolved by restoring erosion
control devices to effective working order. The wetland will be re -flagged to its pre -development limits. After a site inspection by USACE/DWR,
restoration activities will begin, including but not limited to the removal of all fill material, and replanting of wetland flora.
3. Cumulative Impacts (DWQ Requirement)
3a. Will this project (based on past and reasonably anticipated future impacts) result in
❑ Yes ❑x No
additional development, which could impact nearby downstream water quality?
3b. If you answered "yes" to the above, submit a qualitative or quantitative cumulative impact analysis in accordance with the
most recent DWQ policy. If you answered "no," provide a short narrative description.
The town of Green Level's stormwater policy requires the site to meet TSS standards, as well as capture and control the first inch of precipitation,
therefore protecting downstream water quality.

PCN ADDITIONAL AREA FOR EXPLANATIONS/COMMENTS:
D.1a. Avoidance and Minimization:
The stream bisects the property and crossing it was inevitable. The 1st impact to occurs at the top of the
stream upon coming onto our property to minimize impacts to the greater established downstream
portions. The 2nd stream impact also coincides with a roadway crossing. Near the 2' Crossing, there is a
pump station that serves Ph 1 and will serve all of the proposed Ph 2. All of the property will sewer to the
pumpstation and an impact in this vicinity would be needed for that also. Placing the 2nd crossing as we
have chosen, allows much of Ph 2 to sewer to the pump station within the proposed impacts for the road
thereby minimizing total impacts needed by combining the two. A second connection is also needed
between the 2 phases for connectivity and emergency services. As you are aware, there was an old, farm
or logging crossing consistent of a 24" pipe. This crossing was not proposed to be used or upgraded due
to the fact that the some or similar amount of impact would be required due to the size and unknown
installation methods of this pipe. The total impact would also need to be much longer than the existing
pipe and therefore negate any benefits of trying to utilize it. This area and impact is being proposed to be
returned to a vegetated riparian buffer and re-established stream section such that the previous impact
will be completely removed and void. There was no existing permit in place and we do not know the
origin of the pipe or crossing. Lastly, due to the need to collect stormwater from the development for
treatment, the existing and many of the proposed stormwater treatment facilities are located in this
lower portion of the site and would require access for maintenance, which the road impact and crossing
also helps to provide. Therefore, the proposed impact has a greater use and aids in minimizing potential
supplemental impacts that could have been needed for the sewer and stormwater purposes.
D.1b. Specific Measures taken to avoid or minimize the proposed impacts through construction
techniques:
Both impacts associated with access drives and utilities have been designed to be as least intrusive as
possible, utilizing blanket matting on adjacent slopes to prevent loss of sediment into the stream as well
as plunge pools at the outlets instead of rip rap pads to allow water to dissipate flows as well as deep
pools at the outlets of the pipe. We have also tried to install pipes that will fit within the stream cross
section to avoid the contractor needing to widen the channel at the stream inlets and outlets.

DATA LIMITATIONS
The Service's objective of mapping wetlands and a hitats is to produce reconnaissance level
information on the location, type and size of thenEreso " ` es. The maps are prepared from the analysis of
high altitude imagery. Wetla s entifie basdd on vegetation, visible hydrology and geography. A
margin of error is inhe e% gery; thus, detailed on -the -ground inspection of any particular
site may result in revisi0 o wet and boundaries or classification established through image analysis.
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 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.

Base map information shown on this FIRM was provided in digital format by the North Carolina Floodplain
Mapping Program (NCFMP). The source of this information can be determined from the metadata available in the
digital FLOOD database and in the Technical Support Data Notebook (TSDN).
ACCREDITED LEVEE NOTES TO USERS: If an accredited levee note appears on this panel check with your local
community to obtain more information, such as the estimated level of protection provided (which may exceed the
1 -percent -annual -chance level) and Emergency Action Plan, on the levee system(s) shown as providing protection.
To mitigate flood risk in residual risk areas, property owners and residents are encouraged to consider flood
insurance and floodproofing or other protective measures. For more information on flood insurance, interested
parties should visit the FEMA Website at hftp://www.fema.gov/business/nfip/index.shtm.
PROVISIONALLY ACCREDITED LEVEE NOTES TO USERS: If a Provisionally Accredited Levee (PAL) note
appears on this panel, check with your local community to obtain more information, such as the estimated level of
protection provided (which may exceed the 1 -percent -annual -chance level) and Emergency Action Plan, on the
levee system(s) shown as providing protection. To maintain accreditation, the levee owner or community is
required to submit the data and documentation necessary to comply with Section 65.10 of the NFIP regulations.
If the community or owner does not provide the necessary data and documentation or if the data and documentation
provided indicates the levee system does not comply with Section 65.10 requirements, FEMA will revise the flood
hazard and risk information for this area to reflect de -accreditation of the levee system. To mitigate flood risk in
residual risk areas, property owners and residents are encouraged to consider flood insurance and floodproofing
or other protective measures. For more information on flood insurance, interested parties should visit the FEMA
Website at http://www.fema.gov/business/nfip/index.shtm.
LIMIT OF MODERATE WAVE ACTION NOTES TO USERS: For some coastal flooding zones the AE Zone
category has been divided by a Limit of Moderate Wave Action (LiMWA). The LiMWA represents the approximate
landward limit of the 1.5 -foot breaking wave. The effects of wave hazards between the VE Zone and the LiMWA
(or between the shoreline and the LiMWA for areas where VE Zones are not identified) will be similar to, but less
severe than those in the VE Zone.

On -Site Determination for Applicability to the Mitigation Rules (15A NCAC 2H .0500)
Dear Mr. Sheats:
On December 12016, at your request and in your attendance, Sue Homewood conducted an on-site
determination to review features located on the subject project for stream determinations with regards
to the above noted state regulations. David Bailey with the US Army Corps of Engineers was also present
during the site visit.
The Division acknowledges the areas and boundaries identified as jurisdictional wetlands by the USACE.
The attached map accurately depicts all stream determinations conducted during the site visit.
Please note that at the time of this letter, all perennial stream channels and jurisdictional wetlands found
on the property are subject to the mitigation rules cited above. These regulations are subject to change
in the future. In addition, the Jordan Lake Buffer Rules may apply to some streams at this
location, please be sure to contact the local government for further information regarding the
Jordan Lake Buffer Rules.
The owner (or future owners) should notify the Division (and other relevant agencies) of this decision in
any future correspondences concerning this property. This on-site determination shall expire five (5)
years from the date of this letter.

Internet: www.ncdenr.gov - www.ncwater.org

Landowners or affected parties that dispute a determination made by the Division or Delegated Local
Authority that a surface water exists and that it is subject to the buffer rule may request a determination
by the Director. A request for a determination by the Director shall be referred to the Director in writing
c/o 401 & Buffer Permitting Branch, 1650 Mail Service Center, Raleigh, NC 27699-1650. Individuals that
dispute a determination by the Division or Delegated Local Authority that "exempts" surface water from
the buffer rule may ask for an adjudicatory hearing. You must act within 60 days of the date that you
receive this letter. Applicants are hereby notified that the 60 -day statutory appeal time does not start
until the affected party (including downstream and adjacent landowners) is notified of this decision. The
Division recommends that the applicant conduct this notification in order to be certain that third party
appeals are made in a timely manner. To ask for a hearing, send a written petition, which conforms to
Chapter 150B of the North Carolina General Statutes to the Office of Administrative Hearings, 6714 Mail
Service Center, Raleigh, N.C. 27699-6714. This determination is final and binding unless you ask for a
hearing within 60 days.
This letter only addresses the applicability to the mitigation rules and the buffer rules and does not
approve any activity within Waters of the United States or Waters of the State or their associated buffers.
If you have any additional questions or require additional information, please contact me at 336-776-
9693 or [e-mail].

EROSION CONTROL & MAINTENANCE PLAN NOTES:
1. ALL EROSION CONTROL MEASURES SHALL BE CONSTRUCTED IN ACCORDANCE WITH THE STANDARDS, SPECIFICATIONS AND DETAILS OF
THE NC EROSION AND SEDIMENT CONTROL PLANNING AND DESIGN MANUAL OR LATEST EDITION AND BE APPROVED BY NORTH CAROLINA
DEPARTMENT OF ENVIRONMENTAL AND NATURAL RESOURCES PRIOR TO ANY AND ALL GRADING AND/OR CONSTRUCTION OF PROPOSED
SITE. THE APPLICANT HAS THE RESPONSIBILITY TO CONTACT, VERIFY AND ADHERE TO ALL NCDENR SPECIFICATIONS AND CHECKLIST
REQUIREMENTS OF THE STATE, WHICH CAN BE REVIEWED AT THE NCDENR WEBSITE AS FOLLOWS:
HTTP://PORTAL.NCDEN R.ORG[W EB/LR/HOME
2. RETAIN FLOATABLE WIND BLOWN MATERIALS ON SITE BY STORING ALL TRASH AND BUILDING MATERIAL WASTE IN ENCLOSURES UNTIL
DISPOSAL AT OFF-SITE FACILITIES. CHECK ADJACENT AREAS DAILY AND PICK UP CONSTRUCTION WASTE MATERIALS AND DEBRIS THAT
HAVE BLOWN OR WASHED OFF SITE.
3. PERMANENTLY STABILIZE ALL SURFACE AREA WITHIN AND ADJACENT TO THIS SITE THAT IS DISTURBED BY VEHICLES, GRADING AND
OTHER CONSTRUCTION FOR THE PROPOSED FACILITY. STABILIZATION IS OBTAINED WHEN THE DISTURBED SURFACE IS COVERED WITH
STRUCTURES, PAVING AND OR PERENNIAL VEGETATION HAVING A UNIFORM COVERAGE DENSITY OF AT LEAST 70%. APPLY A MINIMUM 4"
OF THE STOCK PILED TOPSOIL TO ALL DISTURBED AREAS PRIOR TO SEEDING. STABILIZATION OF ALL DISTURBED AREA IS REQUIRED
BEFORE TERMINATION OF MAINTENANCE AND REMOVAL OF EROSION CONTROL MEASURES.
4. CONTRACTORS SHALL INSPECT POLLUTION CONTROL MEASURES AT LEAST ONCE EVERY 14 DAYS AND WITHIN 24 HOURS AFTER A STORM
EVENT OF 1/2 INCH OR GREATER. DAMAGED MEASURES THAT PROVE TO BE INEFFECTIVE SHALL BE REPLACED WITH MORE EFFECTIVE
MEASURES OR ADDITIONAL MEASURES WITHIN SEVEN DAYS. REPEATED FAILURE OF A CONTROL MEASURE REQUIRES INSTALLATION OF A
MORE SUITABLE DEVICE TO PREVENT DISCHARGE OF POLLUTANTS FROM THE CONSTRUCTION SITE.
5. INSTALLATION OF ADDITIONAL EROSION CONTROL MEASURES MAY BE REQUIRED BY THE TOWN OR COUNTY. CONTRACTOR TO VERIFY
REQUIREMENTS PRIOR TO BEGINNING ANY WORK ON PROJECT SITE.
6. CARE SHALL BE TAKEN TO MINIMIZE THE ENCROACHMENT OF SEDIMENT INTO ALL STORM DRAIN APPURTENANCES, PUBLIC ROADS, AND
ONTO PRIVATE PROPERTY UNTIL IMPERVIOUS MATERIAL (ROAD/PARKING AREA SURFACE) IS APPLIED OR UNTIL PROPOSED LANDSCAPE
HAS BEEN ESTABLISHED.
7. REFER TO DETAIL SHEET D-5 FOR SILT FENCE CONSTRUCTION.
8. ALL AREAS NOT SHOWN AS PAVEMENT OR BUILDING UNDER FINAL CONSTRUCTION SHALL BE TEMPORARILY AND PERMANENTLY SEEDED
AS REQUIRED. SEE LANDSCAPE PLAN FOR AREAS WHERE PERMANENT SEEDING WILL NOT APPLY.
9. ALL GRASS SLOPES WHICH EXCEED 3:1 (H:V) SHALL UTILIZE NORTH AMERICAN GREEN (NAG) CONSTRUCTION PRODUCTS TURF
REINFORCEMENT MATS SC150 OR APPROVED EQUAL UNLESS OTHERWISE SPECIFIED ON PLANS. MATS SHALL BE INSTALLED PER
MANUFACTURER'S SPECIFICATIONS AND STANDARDS. CONTRACTOR SHALL COORDINATE INSTALLATION INSPECTION WITH
MANUFACTURER.
PHASE 2 CONSTRUCTION SEQUENCE:
1. AFTER COMPLETION AND APPROVAL FOR PHASE 1 MEASURES, PROCEED WITH PHASE 2.
2. BEGIN GRADING OF SITE AS SHOWN, WHILE ADJUSTING DIVERSION DITCHES AS NECESSARY TO DIRECT RUN-OFF WITHIN THE DISTURBED
AREAS TO APPROPRIATE SKIMMER BASINS. STABILIZE ALL AREAS AS THEY ARE BROUGHT UP TO FINAL GRADE.
3. RELOCATE / RE-ESTABLISH TEMPORARY DIVERSION DITCHES AT END OF WORKDAY TO NEW CONSTRUCTED TOP OF SLOPE SUCH THAT
DRAINAGE AREA TO BASIN IS MAXIMIZED AND UPLAND AREAS CAPTURED BY SILT FENCING ARE MINIMIZED. INSTALL TEMPORARY SLOPE
DRAINS TO CONVEY WATER DOWN THE FILL SLOPE TO THE BASIN. UPON COMPLETION OF THE BUILDING PADS, MAINTAIN A DIVERSION AT TOP
OF SLOPE UNTIL PAVEMENT IS INSTALLED AND GRASSED AREAS ARE STABILIZED.
4. INSTALL 2-54" RCP PIPES FOR STREAM CROSSING. ISOLATE STREAM USING TEMPORARY SANDBAGS TO DAM THE CREEK DURING CROSS PIPE
INSTALLATION. PROVIDE PUMP(S) OF ADEQUATE CAPACITY TO MAINTAIN DOWNSTREAM FLOWS CONSISTENT WITH PRE -DEVELOPMENT
ACTIVITIES. PUMP(S) SHALL BE LOCATED IN A SAND BOX MEETING MINIMUM DIAMETER FOR FUEL SPILL REQUIREMENTS. PROVIDE EROSION
CONTROL MEASURES AS SHOWN ON THIS SHEET AND STREAM CROSSING DETAIL SHEET PRIOR TO PIPE INSTALLATION.
5. ONCE GRADING IS NEAR COMPLETE AND ROADS ARE BROUGHT TO SUB -GRADE, INSTALL SANITARY SEWER AND STORM DRAINAGE.
6. ONCE STORM STRUCTURES ARE INSTALLED, PROVIDE INLET PROTECTION TO PREVENT SEDIMENT FROM ENTERING THE STRUCTURES AND
STORM DRAINAGE SYSTEM. INSTALL WATER MAINS AND DRY UTILITIES.
7. CONSTRUCT ROADWAYS AND COMPLETE ALL NECESSARY GRADING, STABILIZE ALL REMAINING DISTURBED AREAS AND CONTINUE TO
MAINTAIN ALL EROSION CONTROL MEASURES.
8. ONCE SITE IS STABILIZED AND PERMISSION IS GIVEN BY THE EROSION CONTROL INSPECTOR, CONVERT SKIMMER BASINS TO PERMANENT
PONDS ACCORDING TO DESIGN DETAILS SHOWN ON THE CONSTRUCTED WETLANDS DETAIL SHEETS.
9. ONCE THE CONSTRUCTED WETLANDS AREAS ARE STABILIZED, CALL FOR FINAL EROSION CONTROL INSPECTION AND SIGN -OFF.
10. AFTER FINAL INSPECTION AND APPROVAL, REMOVE ANY REMAINING EROSION CONTROL MEASURES, SMOOTH GRADE, SEED AND MULCH
THESE AREAS.
CONSTRUCTION ENTRANCE NOTES:
1. CONSTRUCTION ENTRANCE SHALL BE 25' MINIMUM WIDTH AND 50' MINIMUM
LENGTH AND 6" MINIMUM THICKNESS OF STONE (1.5"-3.5") COARSE
AGGREGATE WITH GEOTEXTILE UNDERLINER. REFER TO THE TOWN OR
STATE FOR ANY ADDITIONAL REQUIREMENTS.
2. THE ENTRANCE SHALL BE MAINTAINED IN A CONDITION WHICH WILL
PREVENT TRACKING OR FLOW OF MUD ONTO PUBLIC RIGHT-OF-WAY. THIS

Consult Conservation Engineer or Soil Conservation Service for additional information concerning other alternatives for
vegetation of denuded areas. The above vegetation rates are those which do well under local conditions; other seeding rate
combinations are possible.
***Temporary - Reseed according to optimum season for desired permanent vegetation. Do not allow temporary cover to grow
over 12" in height before mowing, otherwise fescue may be shaded out.
SEEDING SCHEDULE
1.) CHISEL COMPACTED AREAS AND SPREAD TOPSOIL 3 INCHES DEEP OVER ADVERSE SOIL CONDITIONS, IF
AVAILABLE.
2.) RIP THE ENTIRE AREA TO 6 INCHES DEPTH.
3.) REMOVE ALL LOOSE ROCK, ROOTS, AND OTHER OBSTRUCTIONS LEAVING SURFACE REASONABLY
SMOOTH AND UNIFORM.
4.) APPLY AGRICULTURAL LIME, FERTILIZER, AND UNIFORMLY MIX WITH SOIL (SEE BELOW*).
5.) CONTINUE TILLAGE UNTIL A WELL -PULVERIZED, FIRM REASONABLY UNIFORM SEEDBED IS PREPARED 4 TO
6
6.) SEED ON A FRESHLY PREPARED SEEDBED AND SEED LIGHTLY WITH SEEDING EQUIPMENT OR CULTIPACK
7.) MULCH IMMEDIATELY AFTER SEEDING AND
8. INSPECT ALL SEEDED AREAS AND MAKE NECESSARY RESEEDINGS WITHIN THE PLANTING SEASON IF
POSSIBLE. STAND SHOULD BE OVER 60% DAMAGED, REESTABLISH ORIGINAL LIME, FERTILIZER AND SEEDING
RATES.
9.) CONSULT CONSERVATION INSPECTOR ON MAINTENANCE AND FERTILIZATION AFTER PERMANENT COVER

SEEDBED PREPARATION
MAINTENANCE:
NEW SEEDLINGS SHOULD BE INSPECTED FREQUENTLY AND MAINTENANCE PERFORMED AS NEEDED. IF RILLS
ANG GULLIES DEVELOP, THEY MUST BE FILLED, RE -SEEDED, AND MULCHED AS SOON AS POSSIBLE.
DIVERSIONS MAY BE NEEDED UNTIL NEW PLANTS TAKE HOLD.
DAMAGE TO VEGETATION FROM DISEASE, INSECTS, TRAFFIC, ETC., CAN OCCUR AT ANY TIME. HERBICIDES
AND REGULAR MOWING MAY BE NEEDED TO CONTROL WEEDS. DUST AND SPRAYS MAY BE NEEDED TO
CONTROL INSECTS.
WEEK OR DAMAGED SPOTS MUST BE RELIMED, FERTILIZED, MULCHED, AND RESEEDED AS PROMPTLY AS
POSSIBLE.
