2253 [30 JANUARY 2009]
Town of Sullivan’s Island, SC
Alternative 2 – Continue Present Practice
Alternative 2 assumes no change in the existing Town ordinance for pruning by individual prop-
erty owners. Over time, pruned swaths would be flanked by higher stands of forest vegetation.
As the tree canopies of unpruned areas expand, they would tend to narrow the ocean vistas
across pruned areas.
Barrier Island Ecology & Habitat Density
Continued pruning will prevent maritime forest from developing in these areas.
This will maintain altered shrubland habitat and (compared with Alternative 1)
preserve a greater number of distinct habitats. Shrubland areas presently not
pruned will transform into maritime forest with the result being shore-perpendicular
bands of pruned shrubs paralleling unpruned forest (see Fig 1.3).
Pruned areas will maintain bands of dense understory vegetation as vegetative
growth is forced laterally via the pruning process.
Storm Damage Reduction
Pruning will result in a lower shrub cover and incrementally higher storm surge and
damaging waves compared with unpruned vegetation (the impact will be relatively
small for most storms and only become significant during rare storms such as a
100 year event, as described in Section 5.2).
Ocean Views
Views will be maintained along pruned corridors, but are expected to diminish as
adjacent unpruned swaths develop higher vegetative cover.
Beach Access & Public Safety
Pruning shrub vegetation along paths will improve access and leave a dense,
understory edge. This may reduce convenient hiding places and inhibit escape
from paths, thus increasing public safety. Low vegetation along broad paths will
allow users better visibility to see potential dangers and be seen by others, thus
leading to a greater sense of security along access paths.
Fire
Threat of fire will remain similar to present conditions because of continued
presence of dense, understory vegetation along pruned swaths. (See Section 6.2
for discussion of fire threats and management options.)
Pests
Rodent problems will remain the same or increase because of the expansion of
dense understory vegetative cover
Property Values
Maintenance of ocean views across pruned corridors is expected to have a
positive impact on property values and the local tax base. However, as adjacent
unpruned swaths develop higher vegetation, the artificial character of pruned strips
between development and the ocean will become more apparent, possibly
adversely impacting property values compared with other barrier-island oceanfront
properties.
Cost of Implementation
Present costs are mainly borne by individual property owners. Those costs are
expected to increase as sections of grassland habitat become shrubland habitat.
Some property owners who have not engaged in pruning, because their vegetative
cover is presently lower density, may consider pruning in the future as their ocean
views diminish.
Construction Requirements
Same as present with debris removal and disposal being a significant part of the
cost.
