financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts. Roadway wetland crossings
have been avoided and minimized by crossing at the narrowest widths. _and___reducin~ pavement
sections at the crossing areas. Culverts will be used for equalization. Sub-aqueous utilities will
be located within these fill areas to eliminate additional impacts.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
Page 9 of 12

USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on January 15, 2002, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete.

Figure 1 -Site Vicinit~r Map
The existing site is undeveloped and sparsely to moderately wooded with undisturbed upland
and wetland areas with mature trees and under story growth.
The New Hanover County SCS Soil Survey indicates that the predominate soil within the project
limits site is Kureb sand (Kr). The remainder of the property boundary contains Leon sand (Le),
Borrow pits (Bp), Lynn Haven fine sand (Ly), and Dorovan soils (DO). All of these soil types
have well drained soils that have a sand and fine sand surface layer and a sand, fine sandy
loam, and loamy fine sand subsoil or underlying layer; on uplands. The seasonal high water
table is greater than 6 feet below grade.
Page 1

The proposed project area discharges to Cape Fear River. Cape Fear River is within the Cape
Fear River Basin and is classified SC. The classification is dated 08/09/81 and the stream index
number is 18-(71). Wetlands and Coastal Marsh are located within the property boundary;
these areas will be excluded and protected from construction activity.
Proposed Improvements
The proposed development of this 64.62-acre tract of land will be for 33 duplex residential
homes. To provide a safe finished floor elevation, the existing uplands will be built above the
100-year flood elevation (10.0') and protected with the installation of treated timber bulkheads.
The improvements will consist of the clearing and grubbing, wall installation, cross drainage
piping, fill material, roadway and utilities construction.
The infrastructure has been carefully designed to limit the wetland impacts. Of the 64.62-acre
tract of land, 51.13 acres of wetlands are on the property. Six areas of wetlands totaling 0.39
acres will be impacted as a consequence of development. The wetland disturbance is a
requirement for minor roadway and utility crossings. A 10.5/1 ratio (4.10 acres) is proposed for
preservation and mitigation.
stormwater will be treated via infiltration basins and trenches. Roof drains shall tie into the
infiltration trenches. Emergency overflow devices will be set at the 50-yr event in each
individual system. Both the county stormwater regulations and state stormwater regulations will
be accommodated.
The project is being pursued as high density. Wetlands have been excluded from the
impervious area percentage calculation. The impervious area is based on the total property
minus the wetland area. The impervious area will be 66,644 sf of roadways, a 12,685 sf
clubhouse, 31,680 sf of driveways, and 33-lots totaling 74,280 sf, making the total built upon
area 185,289 sf, 62.8% of the 294,900 sf drainage area.
Streets are private but will be constructed to NCDOT standards. Interconnectivity and cul-de-
sac lengths were not obtainable based on the site characteristics. Emergency vehicle "hammer-
heads" are provided in lieu of cul-de-sacs.
Maintenance
Sediment will be removed from the infiltration system annually or when the depth in the unit is
reduced to 75% of the original design depth. A benchmark shall be established in each
individual infiltration system. The system shall be restored to the original design depth without
over excavating. Removed sediment shall be hauled offsite. The bulkhead retaining wall shall
be inspected and maintained annually and after a sufficient storm event. Upon completion of
construction and the establishment of stabilizing ground cover, the property owner shall be
responsible for site maintenance.
