THE VALUE OF DUNE ESTABLISHMENT

Extra Time

The adage that you can't buy time fails when you establish a protective dune line.
The dune cannot withstand continualwave assault, however, the more sand and vege-
tation available, the more wave energy is required to remove protection and make
the structurevulnerable to damage. Therefore, by establishing a dune, you buy
time!
Frequency of Storm Damage
Storms with various intensities occur with different frequencies. The storms with.

the Dunes
greatest intensity occur at far less frequency than do more minor storms-
not only buy time during real intense storms but also preclude, damage for most minor
storms. Dunes lower the probability of damage to properties..

Sand Erosion and Deposition
The movement of sand alongthe beach is relative to the velocity of wind.. When wind
velocity reaches 12 miles per hour, significant erosion and deposition occurs.. When
wind velocities go to extremes such as in nor'easter or hurricanes, sand becomes-so
mobile, it crosses the total city becoming airborne to elevations exceeding and
being deposited on sun-decks nine stories high. The dune traps the sand stopping

its encroachment on the city preventing undesirable deposition,in roads, on lawns.and
against buildings.

Natural Landscape Beauty
The establishment of the vegetative cover on the dunes provides scenic beauty once
typical of all coastal areas. The plants provide diversity to the-environment
cushioning the harsh edge between buildings and sand. Breezes- induce gentle flowing
grass movement where otherwise, there would be only motionless sand. The vegetation
provides habitat for shore birds, rabbits and a base-for outside classrooms.

Cost for Dune Establishment

440' fence for 200 by 20 area
Fence - 440 x 39 = $171.60

Fence Post - 29 x $2.85 $82.00

Plants - 4000 x $85.00 $340.00
Fertilizer - 40 lbs/application/4000 sq. ft., 3 applications of 1.0-10-10
per year, 120 lbs of 10.-10-10 approximately $12.00
Laborfor establishment and fertilizing
Estimated at 4 man days or 32 hrs. at $6.00 or $192.00
Total price $797.60

Now consider the fact that the dunes once established should need maintenance
and that 'Cost should be considered over a ten year duration.

Ist Year Cost
Maintenance cost over 10 years given the following assumptions:
(a) Replace and mend fence (3 times)* .$514.90
(b) Fertilizer at $14.00/year 120.00
(c) Labor at Z men days/yea.r or 16 hours @ $6.00 960.00

$1594.80

Total for 10 years maintenance $2391.18
Or $239.18 per year

1983 Cost Example

Du-ne DeveloDment and Stabilization

Supgested Schedule of Activity

Ocean City, Maryland

1. Establish dune by use of dozer', if available,.through present program.
Fence proposed planting site so as to trap the greatest amount of movin g
sand - September/October. (Snow fencing.materials are acceptable).

2. Contact possible plant material supp2iers and select,best price and delivery
means. Arrange for delivery when planting is scheduled - September-November.

3. Determine if a special.landscape appeal is desired and plan for establishing
irrigation or other needs as deterTnined.

4. Mulch and protect existing vegetation from wind erosion encroachment on
slope S.

5. In late winter or early spring, relocate or place additional fencing around
area proposed to be stabilized to exclude@manls encroach,ment - November-March.
Any fencing materials selected will be acceptable that exclude'man but prefer-
ence should guide selection that will also aid in sand trapping. Fence should be
50% open area.
6.. Plant American beachgrass.from November to March 30th with preference for the
month of February.,

7. Select and apply a recommended fertilization program. Select one which also
enhances plant succession species. (See recommended fertilizer rates) .page 7.

S. Do not remove desirable invasion plant species from stabilization area.,

9. If it is desirable to incorporate shrub species, select desired species and
order. (See plant -selection list) page 6.

10.. Plant shrub species the first,year after beach grass establishment..

.11. Apply slow releasing fertilizer to.shrubs and perform related.maintenance
activities such as irrigation.

PLANT SELECTION

The dune area is a harsh environment, one which combines sand , drought , wind
sun, salt spray and temperature such a manner that sea-side plant estab-
lishment requires selection of adapted, if not specialized plant species.. The
following is a list of plants which have been tried and have met with success
depending on site. If you wish to enhance the landscape appeal at the site
by shrub and vine planting, consider thefollowing:

Eastern Baccharis BACCHARIS HALMIFOLIA
Shore Juniper JUNIPERUS CONFERTA
Waxmyrtle MYRICA CERIFERA
Marsh elder IVA IMBRICATA
Chickasaw Plum PRUNIS AUGUSTIFOLIA
Ruqgosa Rose ROSA RUGOSA
Yucca Sp YUCCA SP

Vines

Trumpetcreeper CAMPSIS RADICANS
Virginia Creeper PARTHENOCISSUS QUINQUEFOUA
Summer Grape VITIS AESTIVALIS
Muscadine Grape VITIS ROTUNDIFOLIA
Sweetautumn Clematis CLEMATIS PANICATA
Wintercreeper EUOINYMUS FORTUNEI

Not suited for dune stabilization

Tree species are not usually selected for dune stabilization along the outside
dune line. Most trees are not suited to the harsh conditions. If you select
to try to establish trees, the following list should be considered:

Japanese Black Pine PINUS THUMBERGII
White Poplar POPULUS ALBA
Black Cherry PRUNUS SEROTINA
Live Oak QUERCUS VIRGINIANA
Eastern Red Cedar JUNIPERUS VIRGINIANA

After the dune becomes established, succession will lead to the encroachment of:
native or wild species. Usually one of the first species to become established
after the beachgrass is the seaside goldenrod. Additional species including
shrubs such as, waxmyrtle tend to follow in successional stages. If fertilization
of the dune is accomplished, succession is hastened. A general rule to follow is.
that any plant growth is beneficial and should not be removed.

Committee Goals

l.increase the number of property owners/managers interested in property pro-
tection through dune stabilization.

2.. Ma.intain a procurement committee whose charge it i s to dete@rmine the
cheapestand best methods to acquire fence materials, fertilizers, plant
materials, labor and other materials as needed.
3. Maintain cooperative relations with all divisions of gove=ent interestet
in proposed activity and others that might be of assistance including con-
servation oriented groups.

4. Obtain assistance in developing a,conservation and dunedevelopment and
5tabilization plan for each land owner who is amember of the group.

5. Establish a preference for early dozer work for participants of the dune
stabilization program if the city continues to.doze sand.

Follow the dune development and stabilization suggested schedule of
activities.

7. Document-successful andunsucessful dune development and stabilization
attemptsaInd the reasons why.

8. Twice a year (May and September) select a committee whosecharge it is to
view the dunes and identify maintenance work that needs to be accomplished.,.

9. Inform the public through news articles of all activities of the organized.
group. Establish an information campaign to increase-and retain group merr,,
bership.

10. Establisb a requirement for city dozer work to be performed only after a
vegetation stabilization plan is developed..

DUNE STABILIZATION

The skunmer of 1983 the Soil Conservation Service in Worchester County caTpleted

a follow-up study of the.dune stabilization project North of 27th Street along

the ocean front'in Ocean City. The results are as follows:

Vegetation:
1. Approximavely 66% of the sites were c6mpletely.de void,
of any appreciable vegetation.
2. Only 2% were,considered to be natural and well covered".
3. 7% were "natural and sparse".'
4. 8% were considered to have "natural.and medium" coverage.
5. 7% were "Planted and well covered".
6. 6% were "Planted and medium".
@7. 4% were "planted. and sparse".

Fencing:
1. 60% of the sites 'had no fencing at all..
2.. 4% were covered with less than 24" of the fence showing.
6% were "broken down - inadequate -for dune formation"_
4. 30% of the sites were "-adequate in good shape".
5. Virtually all of the sites with the exception of those
between 54th and 115th streets were easily accessible, i.e.,
the sites were not adequatelyprotected by fencing.

Dune Height:
1. 42% of the sites.averaged less than I ft.. of height.
-ie sites-averaged 1 ft. to 3 ft.. in height.
2 117. of tl
3. 227. averaged 3 ft. to 5 ft.
4. 25% were 5ft. in height@ or greater,

Vegetative appearance:
1. 66% of the sites were devoid of. vegetation.
2. 26% of the vegetation was considered to be green or vigorous.
3. 8% was considered to be yellow or st.r essed..

Dune Formation:
1. 58% of the siteshad some type.of.dune formation.
42% of the sites had no dune formation.

Please note that the total number of sites equaled .241.
