IV INFILTRATION BASIN OPERATION AND MAINTENANCE AGREEMENT
After every runoff producing rainfall event and at least monthly inspect the Infiltration system for erosion,
trash accumulation, vegetative cover, and general condition
Repair eroded areas Immediately, re -seed as necessary to maintain adequate vegetative cover, mow
vegetated cover to maintain a maximum height of six inches, and remove trash as needed
After every runoff producing rainfall event and at least monthly inspect the bypass, inflow and overflow
structures for blockage and deterioration Remove any blockage and repair the structure to approved design
specifications
Remove accumulated sediment from the pretreatment system and infiltration basin annually or when depth
in the pretreatment unit is reduced to 75% of the original design depth The system shall be restored to the
original design depth without over -excavating Over -excavating may cause the required water table
separation to be reduced and may compromise the ability of the system to perform as designed Removed
sediment shall be disposed of in an appropriate manner and shall not be handled in a manner that will
adversely impact water quality (i e stockpiling near a stormwater treatment device or stream, etc )
A benchmark shall be established in the pretreatment unit The benchmark will document the original
design depth so that accurate sediment accumulation readings can be taken The measuring device used to
determine the depth at the benchmark shall be such that it will give an accurate depth reading and not
readily penetrate into accumulated sediments
When the design depth reads n/a feet in the pretreatment unit, the sediment shall be
removed from both the pretreatment unit and the infiltration basin
If the Division determines that the system is failing, the system will immediately be repaired to original
dc,sign specifications If the system cannot be repaired to perform its design function, other stormwater
control devices as allowed by NCAC 2H 1000 must be designed, approved and constructed
I acknowledge and agree by my signature below that 1 am responsible for the performance of the five

1 Protect Description
The project consists of construction of a 14 budding (43 unit) townhome development This site is located
adjacent to Boathouse Creek, SA,HQW
2 Design Requirements
Project will be designed in accordance with NC Administrative Code Section 15A NCAC 2H 1000 —
Stormwater Management (hereinafter "Regulations" This site is in the category of development activities
within coastal counties except those areas draining to Outstanding Resource Waters or within one-half mile of
and draining to SA water" Due to density, the project is considered 'high density development In
accordance with Section 1105(2)(b) of the Regulations, an infiltration system designed to accommodate 1-1/2"
of rainfall will be required Furthermore, runoff in excess of the design volume must flow overland through a
vegetative filter

Actual storage volume is required to infiltrate completely within 5 days The Stormwater Infiltration Basin
Report (Soil & Site Evaluation) (copy attached) indicates that existing soil conductivity can be as high as 20
m/hr Assuming conservatively that existing soils have a minimum hydraulic conductivity of 6 m/hr,
infiltration rate is computed as follows
Infiltration Rate = Hydraulic Conductivity x Basin Bottom Surface Area
= (6 in /hr) x (4,852 sf) x (1 ft /12 in )
= 2,426 cf/hr
Draw Down Time is then calculated
Draw Down Time = Actual Volume / Infiltration Rate
= 12,862 cf / 2,426 Mir
= 5 30 hr (< 5 days)

To David Newsom <crystalcoasteng@bizec rr com>
David,
A preliminary review of the information submitted with the State Stormwater Permit
Application for Townhomes of Abaco has determined that the following information is
needed to continue the stormwater review
1 The infiltration rate recommended by your soil scientist is 6 in/hr However
the infiltration rate used in the calculations and given in the supplement is 10
in/hr Please use the infiltration rate recommended by your soil scientist
2 Please provide a copy of the wetlands delineation map signed by the Corps of
Engineers, or include a copy of the unsigned delineation map submitted to the
Corps
3 On Sheet 2 of 2 on the Plans the bottom elevation of the infiltration basin is
given as 11 5 fmsl In the section detail on that same page it is shown as 10 50
fmsl and on the supplement it is given as 10 50 fmsl Please verify the bottom
elevation of the infiltration basin
4 Please provide a flow spreader to distribute the flow across basin
5 Please verify the surface area at the bottom elevation of the basin This
surface area appears to be 3,531 square feet as shown on the supplement versus
4 852 square feet as used in the calculations
Please address these comments prior to January 21, 2007

reserves the right to decline to do the investigation If the pioposed infiltration system will be
located in an area of existing pavement and there is no open area nearby, equipment capable of
breaking through the impervious layer must be provided The sods investigation does not take
the place of a sods report prepared by an appropriate professional The Sods Scientist will only
verify the sod conditions that are reported in the Sods Report, and make a determination as to
the suitability of the site to meet the Infiltration design requirements under NCAC 2H 1000, and
assumes no liability should the system fad

Stormwater Treatment
& Erosion Control Narrative
Townhomes of Abaco
Slowflight of Cedar Point, Inc proposes to construct a forty-three (43) unit residential Townhome
development on a 7 13 acre tract located on Abaco Drive (near the intersection of Sherwood Drive
and Marsh Island Drive) in the White Oak Township, Carteret County, N C
The protect is to be designed and constructed in accordance with NC Division of Environmental
Management Stormwater Management Rules (15A NCAC 2H 1000) Section 1005(2)(b) The
proposed development activities are high density (BUA = 32 96%)
The site is located near Boathouse Creek (SA HQW) in the White Oak Basin Existing site
topography is generally gently sloping (0 -10%) with the highest area located at the northeastern
corner of the tract Topography suggests that precipitation currently infiltrates into the sandy soils or
sheet flows into the small area of wetlands (to remain undisturbed) located at the western edge of
the site
The proposed development will include fourteen (14) buildings and associated parking (with curb
and gutter) All stormwater from onsite impervious surfaces will be directed via sheet flow and
stormdrain pipes to the proposed 4,852 sf (bottom area) infiltration basin in the southwestern corner
of the site Stormwater in excess of the first 1 5 will bypass the storage system and be discharged
to a vegetated filter
The proposed infiltration basin is sized to accommodate stormwater from a total of 102,367 square
feet of impervious surfaces, as follows

The entire area designated within "Clearing Limits" will be disturbed during initial construction Silt
fence will be installed at downslope portions of the tract boundary as well as outside of downslope
wetlands boundaries to prevent sediment loss During construction, the infiltration basin will also be
used to contain sediment on site and out of wetlands Therefore, the infiltration basin shall be
installed concurrent with other erosion control devices After the site is stable, the contractor shall
restore the basin to appropriate design depths and contours

Stortnwater Infiltration Basin Report
To Whom It May Concern
Subject Cedar Point Commercial Park, Sherwood Avenue, Cedar Point, NC
A soil and site evaluation was performed at the above referenced 10 acre t site on March 11 2004 The
purpose of the evaluation was to determine conformance with the requirements of Title 15 A NCAC 2H
1008 and the dry infiltration basin criteria specified by Division of Water Quality Form SWU-103 Rev
3 99 While most of the soil on this tract can, to varying degrees qualify for a dry infiltration basin, the site
assessment was limited to the rear most 500' f portion site (eastern end away from Sherwood Avenue)
since that is the natural and preferred stormwater outfall for the proposed street cul-de-sac and buildings,
that is where the complex topography complicates the eastern boundary of usable sod conditions, and that is
prelumnary design locations of the needed infiltration basins
The soils found to have at least 24" to soil wetness colors from the natural land surface with greater than
0 52 infiltration rates and limits of the detailed soil evaluation are shown on the attached map The soil
conditions fall in well within the range of soil characteristics of the Wando soil series and moderately well
drained related drainage catena taxadjuncts When contour lines are computed for the soil sample locations
they are remarkably uniform and provide a relatively large site area for final design of the proposed basins

Cedar Point Commercial Park Intitralion Basin
The soil conditions are most similar to the Carteret County Soil Survey mapping unit description
provided in Addendum 41 The hydraulic conductivity specified by the Carteret County Soil Survey and the
NRCS standard sod description (Addendum #2) of the Wando soil series is 20" per hour Given that
sedimentation sealing of the infiltration surface can be a significant maintenance problem for new and
established soil infiltration systems, I recommend that design infiltration rate be based on 6" per hour The
basin can be located anywhere within the designated usable soil area as long as 24" is maintained from the
basin invert to the soil wetness colors No rock or impervious soil layer exists within 6' of the present land
surface in the delineated sod area Please advise if there is any questions
I, Wayne Ragland , am d Registered Soil Scientist in the State of NC, and hereby affirm that I have
expertise in the determination of depths seasonal high water tables as determined by soil redoximorphic
features and in field determinations of saturated hydraulic conductivity from texture and density sampling
other characteristics relevant to siting stormwater infiltration systems , and that this assessment report and
all related documents is true and correct to the best of my knowledge and experience and represents the
natural soil site conditions evident on March 11, 2004
