Oceanaire Wetland Restoration Plan
Target:
Restore the wetland biological communities, soil conditio~ls, and hydrology on .08 acres of
404 regulated wetlands that have been impacted, due to site activities, to a transitional
condition conducive to a probable recovery to a their original condition to the extent possible.
Restoration Area Benchmarks:
Reestablishment and maintenance of the water table within 12 inches of the soil surface for at
]east l2% of the growing season.
Restoration of hydrophytic vegetation as defined as dominance of greater than 50% of species
with wetland indicator status wetter than FAC.
Site Location and Description:
Oceanaire is located 1.8 miles south of the intersection of Hwy 50 and Hwy 210, on Hwy 50
in the town of Surf City in Pender County. Oceanaire is a 6.56 acre planned low-density
(with no curb or gutter) residential development that drains into the Intercoastal Waterway
(stream classification- SA).
According to the published Soil Survey of Pender County, NC, the soils is mapped as
Newhan-Corolla complex.
Areas targeted for restoration include the utility easement(Conservation Easement II) located
within 10 feet of the Road R/W for lots 9, 10, 1 1, 12, 13, and the pump station area.
Restoration Strategies:
Hydrologic Restoration
Soil structure will normally be restored over time by natural ecological processes. In order to
accelerate re-development of soil structure, restoration methods and equipment shall be
selected to minimize soil damage. The developer shall restore the disturbed 404 regulated
wetland areas to the pre-impacted surface grade. Restoring the pre-impacted grade should, in
turn, recreate the original topographic gradient. This should expedite the restoration of proper
hydrological characteristics of the pre-impacted site by creating the proper environment for
redox conditions to occur within the upper horizons of a hydric soil.
Filled wetland areas will be graded to the pre-impacted surface grade. Simple topographic
measurements from adjacent, non-impacted areas will suffice to set base elevations for the
necessary grading.

~r1L ION ~NGI~~L,ERI1~'
Original micro-topography shall be re-created to the extent possible. Ruts, stump holes and
any other mechanized disturbances shall be filled in and leveled, removing extreme field bed
or crowns using displaced soil. The re-graded surface shall be roughed over with a plow or
other equipment to re-create the micro-topography. Simple topographic measurements from
non-impacted areas will suffice to set base elevations for necessary grading. Silt fencing will
be added to protect the restored areas to prevent further disturbances and deposition of fill
material from erosion. Upland areas adjacent to restored wetlands will also be graded to a 3:
slope and seeded to prevent future deposition of fill material in the wetlands once the silt
fencing is removed.
Vegetative Restoration
Typical dominant plant species in the adjacent unaffected wetland areas ai-e Polygonunz
punctatum, Persea borbonia, Smilax bona-nox, Sci~puss spp, and Magnolia virginiana.
The restored grade and stabilization of the impacted area should create the potential for soil
redox conditions that are conducive for the growth of the typical vegetation of the non-
impacted, adjacent wetlands. The shrub and herb strata shall be allowed to re-establish
voluntarily, due to the potential seed source being in close proximity to the restoration sites.
Monitoring
A three year monitoring plan shall be implemented, utilizing photos and stem counts. The
report will be submitted in early April of each year.

With its roots immersed in the
mud or water, the bulrush grows
into large, thick colonies. The
plants can reach up to 10 feet tall,
and the tops are crowned with
spikelets.
7.Cladium jamaicense: Saw Grass
Saw grass grows to about 6 or 7 feet tall, with long, slender, narrow leaves
that look like tall blades of grass. These leaves are stiff and tough, with tiny
saw teeth around the edges. The top of saw grass has many branches and
branchlets.

Cattails are easily recognizable by their flower spikes, or cat tails. Cattail
spikes can grow up to a foot long and are densely packed with tiny brown
flowers. The cattail plant can grow to 10 feet tall. Cattails also commonly
grow outside coastal wetlands along freshwater ponds, lakes, rivers and
ditches.

Salt meadow hay is a low- to medium-height perennial wire-like grass, 1-foot- to 3-
feet-tall. It forms dense mats of plants just above the high tide line.
10. Spartina cynosuroides: Salt Reed or Giant
Cordgrass
Salt reed is a member of the same family as salt marsh cordgrass, and they
have similar features. As its name might suggest, this grass grows taller (up

Coastal Wetlands :: Get to Know Them
While Section 404 of the federal Clean Water Act regulates all types of wetlands, including coastal wetlands,
North Carolina's Coastal Area Management Act (CAMA) provides additional protection to coastal wetlands.
CAMA defines a coastal wetland as any marsh subject to regular or occasional flooding by wind or lunar tides.
These marshlands must contain some, but not necessarily all, of 10 particular wetland plants discussed below.
For the most part, it's easy to identify coastal wetlands. They generally are located adjacent to salty water, such
as a sound or other brackish water body. They are characterized by marsh grasses and rarely contain trees.
Although other non-coastal wetlands may be located adjacent to coastal wetlands, non-coastal wetlands are not
typically flooded by salty or brackish waters and are usually characterized by stands of trees or taller brush.
Coastal wetlands can be identified by determining if some of the following 10 plant species are present in the
marsh land area'
1. Spartina altemitlora: Salt Marsh Cordgrass {Smooth Cordgrass)
Salt marsh cordgrass is the most common plant and prime indicator of a coastal wetland. It forms 1-foot- to 8-
foot-tall meadows that grow just up to the open water's edge. Lush and green in the warmer months, salt marsh
cordgrass becomes golden-brown in the fall and dies back in the winter. Salt marsh cordgrass is frequently
flooded.
2. Juncus roemerianus:
Black Needlerush
Black needlerush has tall (3 to 5 feet) needle-like blades in shades of
dark green or gray with sharp blackish tips. It grows in the higher areas
of the marsh, or where salt water completely covers the land only during
unusually high tides. In these higher elevations of the marsh, needlerush
replaces cordgrass as the most common plant species.
3. Salicornia spp.: Glasswort
Glasswort is found throughout the
marsh, mixed in with cordgrass or on the mud flats. Glasswort grows low
to the ground (rarely over 2 feet tall) and has short fleshy green stubby
spikes extending from a main stem. Glasswort looks like long green pipe
cleaners attached to a long stem. Three species are found in coastal
marshes, and one turns pink in the fall.
4. Distichlis
Grass
Salt grass is a short, green, wiry
grass that lives among the salt meadow grass above the high tide line.
5. Limonium spp.: Sea Lavender
~` ~~'~~~~ I Sea Lavender grows at the fringe of the upper intertidal marsh. The plant
looks delicate, with long, skinny leaves that sprout small stems as they
grow upward. These stems are covered with tiny purplish-white flowers in the summer and fall.
