1.0 INTRODUCTION WEWS AND STORMWAWA NVM
The City of High Point, NC (City) and Seaboard Group II (Seaboard) propose the
establishment of a Randleman Lake Water Supply Watershed riparian buffer restoration
project at the Cedrow Park Riparian Buffer Mitigation Site (Site) located at Cedrow Park,
High Point, Guilford County, NC (see attached maps).
The Site is being developed per this mitigation plan to provide riparian buffer restoration
to satisfy Condition No. 3 of the Major Variance Approval (DWQ # 20033-1554v2)
issued to the City on January 1, 2010 and as modified by the N.C. Environmental
Management Commission (EMC) at their meeting held on May 13, 2010.
The approximately 46,710-square foot (sf) area of riparian buffer restoration that will be
performed at the Site was approved by the EMC to satisfy in whole the buffer mitigation
area required to compensate for the loss of 25,575 sf of riparian buffer approved to be
impacted under the major variance.
The Site is located within the Randleman Lake Water Supply Watershed of the Deep
River Watershed, Cape Fear River Basin (USGS 8-digit Hydrologic Unit Code No.
03030003). Specifically, the unnamed tributary streams on the Site drain to the Deep
River (DWQ 03-06-08, 17-(3.3), WS-IV*, Critical Water Supply 15A NCAC 2B .0248).
This document serves as the Mitigation Plan for the Site, which encompasses
approximately 1.07 acres of a single parcel of land approximately 10.47 acres in size.
The parcel is owned in whole by the City of High Point and is managed as a City
neighborhood park called "Cedrow Park" (htip://www.high-point.net/pr/cedrow.cfm ).
The Site generally consists of an inter-stream divide area between a perennial stream
("southern stream") and an intermittent stream ("eastern stream"). Both streams were
Page 1 of 17 0
CEDROW PARK RIPARIAN BUFFER MITIGATION PLAN S&EC 5-1201
City of High Point, NC July 2, 2010
determined by the N.C. Division of Water Quality (DWQ) staff to be subject to the
Randleman Lake riparian buffer rules. This inter-stream divide area is a former ball field
that is no longer in use and remains vegetated in grass and regularly mowed by the City.
The Site will be planted with four (4) native hardwood tree species at a density sufficient
to provide at least 320 trees per acre at the end of the five (5) years. To accomplish this,
approximately 730 trees seedlings will be planted on the Site using 8' x 8' spacing (681
trees per acres). The Site will be protected under perpetual restrictive covenants (sample
attached). A copy of the recorded restrictive covenants will be provided to DWQ.
Annual reports will be submitted to the DWQ for a period of five years after the
restoration showing which trees have survived and that diffuse flow has been maintained.
Any trees that do not survive will be replaced such that there will be at least 320 trees per
acre at end of the 5-year monitoring period. Diffuse flow will be restored if needed.
Directions to the Mitigation Site:
¦ From Winston-Salem, NC travel I-40 east to NC-311 south,
¦ Travel south on NC-311 approximately 14 miles to Greensboro Road/US-29,
¦ Turn left (east) onto Greensboro Rd and take first right (south) onto Enterprise Dr,
¦ Travel Enterprise Drive south to Cedrow Drive,
¦ Turn left onto Cedrow Drive and travel for approximately 0.5 miles,
¦ The Site will be on the right, look for Cedrow Park sign.
¦ Point near center of Site: Latitude 35.97305 / Longitude -079.96099
2.0 OBJECTIVES
The primary goals of this riparian buffer mitigation project focus on promoting
sustainability and improvement of aquatic resources and water quality within the
Randleman Lake Water Supply Watershed. Restoration and protection of riparian buffers
through planting and use of perpetual restrictive covenants are likely to result in net gains
in water quality and habitat functions of the Site streams. Primary goals will be
accomplished through the following measures:
¦ Reforestation of over 1.07 acres of riparian area along two streams.
¦ Increasing Site capacity for nutrient removal and reducing pollution from
stormwater runoff from off-site, non-point sources.
¦ Perpetually providing a diverse woody vegetative buffer adjacent to Site streams.
¦ Reducing nutrient loading from the Site, by eliminating future fertilization and
maintenance of the grass areas.
¦ Reducing the amount of habitat fragmentation and providing a wildlife corridor
and refuge for desirable species in an otherwise urbanized area.

CEDROW PARK RIPARIAN BUFFER MITIGATION PLAN S&EC 5-1201
City of High Point, NC July 2, 2010
Deterring use of Site by urban, nuisance Canada Geese by reforesting the
currently maintained grass areas, thereby reducing or eliminating the associated
problems with excessive Goose-droppings and the potential resulting elevated
bacteria levels via fecal coliform.
These goals will be achieved through the following measures:
¦ Providing approximately 46,710 sf of riparian buffer restoration.
¦ Protecting the Site in perpetuity with appropriate legal mechanisms (e.g.,
perpetual restrictive covenants).
3.0 SITE SELECTION
Primary considerations for site selection include in-kind riparian buffer mitigation and
the potential for protection/improvement of water quality of a water supply reservoir
(Randleman Lake) within a currently urbanized area of North Carolina and under future
developmental pressure. More specifically, considerations include desired aquatic
resource functions, hydrological conditions, soil characteristics, aquatic habitat diversity,
habitat connectivity, compatibility with adjacent land uses, reasonably foreseeable effects
the mitigation project will have on ecologically important aquatic and terrestrial
resources, and potential development trends and land use changes.
The proposed mitigation will result in perpetual protection of reforested riparian buffers
which help protect the drinking water for the region. According to the Cape Fear River
Basinwide Water Quality Plan (NCDWQ 2005), "the watershed (03-06-08) is forested in
the south, but has large developed areas in the northern portion. Development is
occurring between Greensboro and High Point. Population is expected to grow by
265, 000 people in counties with portions or all of their areas in this subbasin by 2020. "
The report goes on to recommend; "It is recommended that High Point and Greensboro
address water quality problems identified above through their respective stormwater
programs, including the reductions in fecal coliform bacteria specified in the TMDL. "
Site selection criteria included:
¦ Located within Randleman Lake Water Supply Watershed where the riparian
buffer impacts approved under the variance will occur.
¦ Existence of riparian areas along surface waters subject to the Randleman Buffer
Rule which are in need of restoration or enhancement, and which are conducive
to the mitigation requirements typical for restoration or enhancement projects
(including at least 50 feet wide, 320 trees per acre, restrictive covenants, etc.).
Properties already owned or controlled by the City (preferably a single property)
to ensure a higher potential for success, long-term management and cost
effectiveness.

CEDROW PARK RIPARIAN BUFFER MITIGATION PLAN S&EC 5-1201
City of High Point, NC July 2, 2010
Several potential sites were identified and evaluated in early 2010 including; Riverdale
Landfill, Grimes-Taylor Stream Restoration Site, Eastwood Park, Washington Terrace
Park, McCain Park, Armstrong Park and Cedrow Park.
¦ No potential riparian buffer mitigation sites were found to exist on the Riverdale
Landfill property.
Grimes-Taylor, a stream restoration and flood control project currently under
construction by the City and not previously proposed for compensatory mitigation
credits, was identified as a site that could potentially meet all of the site selection
criteria. A site meeting with Ms. Sue Homewood of the DWQ was held on
February 3, 2010. It was determined that the nature of the project (flood control)
and adjacent riparian activities (greenway, sewer, etc.) would not make the site
conducive to the requirements typical for restoration or enhancement projects.
Eastwood Park was determined by S&EC and confirmed by DWQ that there was
potential buffer restoration along the south side of the perennial stream which
bisects the park. The north side was not conducive to restoration or enhancement
given the vicinity of a parallel sewer line. Eventually the site was dismissed due
to costs associated with relocating an existing picnic shelter and the limited
amount of restoration area available.
¦ Washington Terrace Park, McCain Park, and Armstrong Park were determined
not to be conducive for buffer restoration or enhancement due to future
management and maintenance needs of the City.
Cedrow Park was determined to be the best potential candidate for buffer
mitigation. A site meeting was held with Ms. Sue Homewood on May 3, 2010 in
which she confirmed the subjectivity of the Site streams, existing vegetation and
potential for buffer restoration. The Site was presented to the EMC at their May
13, 2010 meeting and was approved to satisfy the buffer mitigation condition of
the variance approval.
4.0 SITE PROTECTION INSTRUMENT
The City will place restrictive covenants (sample attached) on the 1.07 acres identified as
the Site and provide a copy of the recorded covenants to DWQ. The City will survey the
Site boundaries to be referenced in the recorded restrictive covenants. The City will
maintain ownership of the Site and enforce the terms of the preservation instruments
(restrictive covenants). A sample of restrictive covenants are attached, the City will
provide the DWQ a copy of the recorded restrictive covenants.
5.0 BASELINE INFORMATION
Site aquatic resources are similar to those found at the Riverdale Landfill (the impact
Page 4 of 17 E
CEDROW PARK RIPARIAN BUFFER MITIGATION PLAN S&EC 5-1201
City of High Point, NC July 2, 2010
site), located approximately 3 miles southeast of the Site. Surrounding lands support
primarily maintained park land and facilities (parking lots, ball fields, picnic shelters,
etc.), residential neighborhoods, and vacant forested land within offsite and abutting
riparian corridors. Water quality functions include sediment retention, toxicant and
nutrient reduction and transformation, and bacterial and viral reduction of watershed
runoff. Habitat functions include a complexity of physical structures, a reduction of
habitat fragmentation, and travel corridors.
5.1 PHYSIOGRAPHY, TOPOGRAPHY, AND LAND USE
The Site is located in the Southern Outer Piedmont (45b) ecoregion of North
Carolina within USGS HUC 03030003 (North Carolina Division of Water Quality
[NCDWQ] Subbasin Number 03-06-08) of the Cape Fear River Basin. Regional
physiography is characterized by lands typical within the Southern Outer
Piedmont. Typical landforms include irregular plains. Elevations within Site
range from a high of approximately 812 feet National Geodetic Vertical Datum
(NGVD) on northern slope to a low of approximately 807 feet NGVD at the
lowest, southeastern point of the Site adjacent to the streams. See attached figures
for topography within the watershed and Site.
The Site provides water quality functions to a 0.25-square mile watershed at the
point where the streams leave the Site. The watershed is dominated by residential
neighborhoods and City roads, park facilities and some sparse wooded areas.
Runoff from the built upon surfaces including parking lots and City roads,
primarily Cedrow Drive enter the Site and streams.
Surrounding area land use is primarily maintained park land and facilities at the
10.47 acre Cedrow Park (including parking lots, ball fields, picnic shelters, etc.),
residential neighborhoods, and vacant forested land within offsite and abutting
riparian corridors. On-site land use is characterized by a former ball field that is
no longer in use and remains vegetated in fescue grass and regularly mowed by
the City of High Point, Parks and Recreation Department. Forested lands adjacent
to the Site are characterized by loblolly pines (Pinus taeda), oaks (Quercus spp.),
hickories (Cary spp.), sycamores (Platanus occidentalis), red maple (Acer
rubrum), sweetgum (Liquidambar styraciflua), and green ash (Fraxinus
pennsylvanica). Approximately 9,200 sf of forest vegetation exists adjacent to the
streams within Zone 1 of the buffer.
The Site is bounded to the north and west by an existing subsurface raw water
line. A 20' setback from the raw water line is specified for the planting. In
addition, an aerial sewer pipe exists along the eastern property line. A 20' wide
easement (10' per side) will be maintained (not planted) along the pipe for access
purposes.
5.2 JURISDICTIONAL STREAMS AND WETLANDS
The main hydrologic features of the Site include unnamed tributary streams. The
unnamed tributaries tend to be characterized by relatively stable banks for urban
streams. A narrow undisturbed forested buffer (0 to 15 feet wide, approximately
Page 5 of 17 M
CEDROW PARK RIPARIAN BUFFER MITIGATION PLAN S&EC 5-1201
City of High Point, NC July 2, 2010
9,200 sf) exists along these streams on the side of the Site. A significantly larger
(>50 feet) undisturbed forested buffer exists on the opposite side of the stream
from the Site.
The "southern stream" within the Site may be generally characterized as a zero
order (per USGS map), headwater, upper perennial stream with unconsolidated
bottoms consisting of clay, sand, gravel and coble. The southern stream begins
offsite to the west, flows east along the southern boundary of the Site, and drains
offsite again to the east. While this stream is not depicted on the USGS
topographic map, two perennial ponds are shown within the drainage and
upstream of the Site, and it is shown as an intermittent stream on the USDA
Guilford County Soil Survey. S&EC determined the stream to be perennial using
current field based DWQ methodologies (i.e., NC DWQ Methodology for
Identification of Intermittent and Perennial Streams and Their Origins Manual
v4.0).
The "eastern stream" within the Site may generally be characterized as a zero
order (per USGS map) headwater, upper intermittent stream with streambeds
consisting of clay, gravel, sand and mud. The eastern stream begins at a City
stormwater pipe outlet and rock dissipater pad, flows south along the eastern
boundary of the Site, drains offsite to the southeast and into the southern stream.
The stream is not depicted on either the USGS or Soil Survey maps. S&EC
determined the stream to be intermittent using current field based DWQ
methodologies (i.e., DWQ Intermittent and Perennial Stream Identification
Manual v4.0).
The Site currently encompasses approximately 375 linear feet of total stream
channel; characteristics of each are included in the table below.

No jurisdictional wetlands were found to exist on the Site.
5.3 WATER QUALITY
The Site is located in the Deep River portion of the Cape Fear River Basin (USGS
8-digit Hydrologic Unit 03030003) of the South Atlantic/Gulf Region (NCDWQ
Subbasin Number 03-06-08). This section of the Deep River has been assigned
Stream Index Number 17-(3.3) and a Best Usage Classification of WS-IV*,
Page 6 of 17 E
CEDROW PARK RIPARIAN BUFFER MITIGATION PLAN S&EC 5-1201
City of High Point, NC July 2, 2010
Critical Water Supply 15A NCAC 02B .0248.
Streams with a designation of WS-IV are protected as water supplies which are
generally in moderately to highly developed watersheds. Local programs to
control non-point sources and stormwater discharges of pollution are required.
These waters are suitable for all Class C uses including aquatic life propagation
and survival, fishing, wildlife, secondary recreation, and agriculture. Secondary
recreation includes wading, boating, and other uses not involving human body
contact with waters on an organized or frequent basis.
All waters of the Randleman Lake (Deep River) water supply watershed are
classified for water supply and designated by the EMC as a Critical Water Supply
Watershed pursuant to G.S. 143-214.5(b), and regulated under the Randleman
Lake Water Supply Watershed: Nutrient Management Strategy (15A NCAC 02B
.0248.
NCDWQ has assembled a list of impaired waterbodies according to the Clean
Water Act Section 303(d) and 40 CFR 130.7, which is a comprehensive public
accounting of all impaired waterbodies. An impaired waterbody is one that does
not meet water quality standards including designated uses, numeric and narrative
criteria, and anti-degradation requirements defined in 40 CFR 131. This section
of the Deep River is not listed on the NCDWQ Draft 2008 303(d) list (NCDWQ
2010).
A locally named lake (Linthicum Lake) exists on the unnamed tributary just
downstream and off of the Site.
5.4 VEGETATION
The vegetation on the Site consists of a maintained fescue grass field. The
surrounding wooded areas primarily on the opposite side of the streams most
closely represent a Basic Mesic Forest Piedmont Subtype (Schafale and Weakley
1990). Field surveys revealed that examples of these forests on-site consist of a
somewhat thick understory or shrub layer. The canopy consists of a mixture of
bottomland and mesophytic trees including but not restricted to Loblolly Pine
(Pinus taeda), Ash (Fraxinus spp.), Sweet Gum (Liquidambar styraciflua),
Sycamore (Platanus occidentalis), Tulip Tree (Liriodendron tulipifera), American
Elm (Ulmus americana), Red Oak (Quercus rubra), Eastern Red Cedar
(Juniperus virginiana) and Red Maple (Acer rubrum). Understory and shrub
species include Privet (Ligustrum sinense), Ironwood (Carpinus caroliniana),
Hophornbean (Ostrya virginiana), Redbud (Cercis canadensis), Buckeye
(Aesculus spp.), and Dogwood (Corpus florida). Other species include but are not
restricted to: Japanese Stiltgrass (Microstegium vimineum), Poison Ivy
(Toxicodendron radicans), Cane (Arundinaria spp.), and Virginia Creeper
(Parthenocissus virginiana).
5.5 SOILS AND LAND FORM
Page 7 of 17 E
CEDROW PARK RIPARIAN BUFFER MITIGATION PLAN S&EC 5-1201
City of High Point, NC July 2, 2010
According to the Guilford County Soil Survey map (NRCS 1997), soil series
located within the Site boundary predominately include Mecklenburg (Ultic
Hapludalfs) and Chewacla (Fluvaquentic Dystrudepts), as well as Urban Land.
Characteristics of these soil series from the USDA Soil Series Descriptions are
detailed below. See attached soil survey map.
Table 2. Stinking Creek Mitigation Site Soils
Map
Unit
Symbol Map Unit
Name Hydric
Status
Description
ChA Chewacla- Hydric This series consists of poorly drained, moderately high
Wehadkee to highly permeable soils on floodplains and is
sandy loam frequently flooded. Slopes are generally between 0
and 2 percent. Depth to the seasonal high water table
is 6 to 18 inches. Bedrock occurs at a depth of more
than 60 inches.
MuB Mecklenburg- Non- This series consists of well drained, typically found on
Urban Land hydric long narrow side-slopes in uplands. Slopes are
complex generally between 2 and 10 percent. Depth to
sandy clay loam seasonal high water table occurs greater than 6 feet.
Bedrock occurs at a depth of 48 to 60 inches.
Soil borings taken by Wendell Overby a NC Licensed Soil Scientist indicated clay
and clay loam-textured fill material in the planting area. Additionally, surface
rocks were observed in portions of the planting area. However, sufficient soil
material appears to exist for supporting the proposed plantings.
Urban Land soils are identified in the Guilford County Soil Survey as "greatly
altered" (cutting, filling, grading, etc.), with a major concern being runoff and
"siltation hazard". The reforestation and deep rooted tree species proposed in
this plan will help alleviate these major concerns.
5.6 FEDERALLY PROTECTED SPECIES
Species with the classification of Endangered (E), Threatened (T), or officially
Proposed (P) such listing are protected under the Endangered Species Act of 1973
(ESA), as amended (16 U.S.C 1531 et seq.). One species is federally listed for
Guilford County by the U.S. Fish and Wildlife Service (USFWS) (USFWS 2008):
Small Whorled Pogonia (Isotria medeoloides) [NC-E; US-T]. Additionally, the
Bald Eagle (Haliaeetus leucocephalus) [NC-T] is protected by the Bald and
Golden Eagle Protection Act.
In addition to the Bald Eagle and E, T, and P species, the USFWS list includes a
category of species designated as "Federal Species of Concern" (FSC). A species
with this designation is one that may or may not be listed in the future (formerly
C2 candidate species or species under consideration for listing for which there is
insufficient information to support listing). The FSC designation provides no
federal protection under the ESA for the species listed; however, North Carolina
Wildlife Resources Commission (NCWRC) provides protection for State Listed
Species - Endangered, Threatened and Special Concern (E, T and SC
Page 8 of 17 E
CEDROW PARK RIPARIAN BUFFER MITIGATION PLAN S&EC 5-1201
City of High Point, NC July 2, 2010
respectively) pursuant to NC General Statutes Chapter 113, § 332. Two species
are federally listed for Guilford County by the U.S. Fish and Wildlife Service
(USFWS) (USFWS 2008): Carolina Creekshell (Villosa vaughaniana) [NC-E;
US-FSC], and Carolina Darter - Eastern Piedmont Population (Etheostoma collis
pop. 2) [NC-SC; US-FSC].
There is no potential or suitable habitat for any of these species on Site, given the
Site is a maintained fescue ball field. The restoration of the forest community
may result in suitable habitat for Small Whorled Pogonia, but this is not
anticipated to occur until many years after planting. Small Whorled Pogonia
prefers acidic soils, in dry to mesic second-growth, deciduous or deciduous-
coniferous forests; typically with light to moderate leaf litter, an open herb layer
(occasionally dense ferns), moderate to light shrub layer, and relatively open
canopy (Flora of North America 2002). Isotria medeoloides frequently occurs on
flats or slope bases near canopy breaks (Flora of North America 2002).
6.0 MITIGATION CONDITION COMPLIANCE
The Site and mitigation plan once implemented will satisfy all riparian buffer mitigation
conditions and requirements of the Major Variance Approval (DWQ # 20033-1554v2)
issued to the City on January 1, 2010 and as modified by the N.C. Environmental
Management Commission (EMC) at their meeting held on May 13, 2010.
Table 2 - Mitigation & Restoration Areas:
Proposed Mitigation Area of Buffer Area of Required Area of Riparian Buffer
Activity Impact Mitigation Restoration
Riparian Buffer
Restoration 25,575 sf 38,903 sf 46,710 sf
The City and Seaboard intend to proceed with impacting the riparian buffers approved
under the Major Variance as early as the week of July 5, 2010. As noted in the schedule,
work at the Cedrow Park Riparian Buffer Restoration Site will commence immediately
upon submittal of this mitigation plan. However, planting will not occur until the
planting season (sometime between January and March 2011).
7.0 MITIGATION WORK PLAN
The primary goals of this mitigation plan include; 1) reforestation of over 1.07 acres of
riparian area along two streams, 2) increasing Site capacity for nutrient removal and
reducing pollution from stormwater runoff from off-site, non-point sources, 3)
perpetually providing a diverse woody vegetative buffer adjacent to Site streams, 4)
reducing nutrient loading from the Site, by eliminating future fertilization and
maintenance of the grass areas, 5) reducing the amount of habitat fragmentation and
providing a wildlife corridor and refuge for desirable species in an otherwise urbanized
Page 9 of 17 E
CEDROW PARK RIPARIAN BUFFER MITIGATION PLAN S&EC 5-1201
City of High Point, NC July 2, 2010
area, 6) deterring use of Site by urban, nuisance Canada Geese by reforesting the
currently maintained grass areas, thereby reducing or eliminating the associated problems
with excessive Goose-droppings and the potential resulting elevated bacteria levels via
fecal coliform, and 7) establishing perpetual restrictive covenants which will encompass
all mitigation activities.
Primary activities include riparian buffer restoration. The mitigation concept is expected
to achieve the following:
¦ Providing approximately 46,710 sf of riparian buffer restoration.
• Protecting the Site in perpetuity with appropriate legal mechanisms (e.g.,
perpetual restrictive covenants).
7.1 VEGETATION PLAN
Applicants propose planting approximately 1.07 acres (46,710 so of the park between
the two streams beyond existing riparian vegetation (see attached map). Planting
areas include and exceed the 50' distance from top of bank (Zones 1 and 2) subject to
the Lake Randleman riparian buffer rules (see planting map).
Willow oak (Quercus phellos), green ash (Fraxinus pennsylvanica), yellow poplar
(Liriodendron tulipifera) and Eastern Redbud (Cercis Canadensis) trees will be
planted at an 8' x 8' spacing (681 trees/acre) within the proposed planting area. The
planting material was chosen based on heartiness, site adaptation, fruit production for
wildlife, and aesthetics. Bare root stock will be machine planted via a 14" deep
ripped trench. Trees will be planted in a random pattern with colored pin flags placed
adjacent to trees for identification purposes. Planting is scheduled to occur in the
winter of 2010. Site preparation will involve use of Accord herbicide applied in 40"
banded strips. Herbicide application will be performed fall 2010, prior to planting.
City maintenance of existing vegetation (mowing) should continue until mid August
2010. A 3'x3' to 4'x4' "weed barrier" (e.g., Vispore tree mat or similiar commercial
weed barrier material) will be used around each sapling.
In all, 1.07 acres of the park (46,710 so will be planted. More specifically,
approximately 11,085 sf of area will be planted between existing vegetation and 50'
from top of bank. Between 50' and 100' from top of bank approximately 18,917 sf of
area will be planted. Approximately 16,708 sf of buffer area will be planted beyond
100' from the stream top of bank.
7.2 GRADING PLAN
The Site is relatively stable with no signs of active erosion or gullies. As such,
grading is not proposed as part of this mitigation plan.
7.2 FERTILIZATION PLAN
A one time application of fertilizer at the time of planting is all that is proposed at this
time. DWQ will be notified of any additional fertilizer applications.

City of High Point, NC July 2, 2010
9.0 PERFORMANCE STANDARDS
Preservation-related portions of the project will be deemed successful if photo
documentation and post planting counts of the Site indicate that at least 320 per acre have
been planted and have survived at the end of the five year monitoring period. Once the
project has been deemed successful riparian functions will be protected through
restrictive land uses outlined in perpetual restrictive covenants.
10.0 MONITORING REOUIREMENTS
Within one year of the date of this mitigation plan, the City and Seaboard will present
proof to the DWQ that he riparian buffer plantings have been installed. They will submit
annual monitoring reports on or before June 1St for a period of five years (as outlined in
the schedule provided in Table 3, Section 7.4). These reports will provide
documentation that the following has occurred and the findings of these activities;
¦ Perform survival count of planted trees. Inspect trees for disease and
insectibrowse damage.
¦ Site photos and tree counts will be performed.
¦ Inspect and document that diffuse flow has been maintained, that no formation of
erosion gullies has occurred. Perform corrective action to restore diffuse flow as
necessary.
Maintenance of property boundaries, signage, fences.
11.0 LONG-TERM MANAGEMENT PLAN
The City will own on the Site. The City will provide for the long-term preservation and
management of the Site. The City will take all actions necessary to enforce the terms,
conditions and restrictions of the restrictive covenants.
