- blue crab (Callinectes sapidus)
- red drum (Sciaenops occellatus)
- spotted seatrout (Cynoscion nebulosus)
- mullet (Mugil sp.)

Acres of Habitat To be Restored:
27
Project Summary:
The project area has lost 60 acres of sea grass area
and salt marsh between 1956 and 1995. The project is
to recover 27 acres of lost marsh habitat, including,
20 acres of intertidal marsh, 7 acres of sand flats
and protect the shoreline from further erosion.
Project would involve placing 730 meters (2438 linear
feet) of 4.5 meter diameter geotextile fiber tubes
filled with sand. The sand used is dredged material
from the Isla Del Sol Subdivision channel. The sand
filled geotextile tube will be place on the north
shoreline in front of existing marsh. The dredge
material is estimated to be approximately 15,000 cu.
yd. The Geotextile tubes would require 3400 cu. yd of
sand leaving approximately 11,600 cu. yd. of material
to build ¼ acre mounds or terraces behind the tubes.
Need for Project:
The Isla Del Sol subdivision has a recreational boat
canal that requires dredging approximately every 5
years to maintain a 5 foot depth and the maintenance
dredge material needs to be disposed of in a
beneficial use.
Project Objective:
Objective of the project is to perform maintenance
dredging and utilize the dredge material in the
restoration of loss salt marsh habitat and shoreline
protection.
On-The-Ground Activities:
- Get permit application no. 23905 approved by the Army
Corps of Engineers. Application was submitted August 8,
2005 and the Corps has asked for additional
information. The requested information will be
submitted by October 31, 2005.
- Get a land survey for the Coastal Lease (LSLS).
- Isla Del Sol Home Owners Association to get Board
approval for $50,000 in 2006 budget for use in
restoration project. Projected approval in December
2005 board meeting.
- Complete match funding with other entities.
- Complete Engineering Design of project. Presently
utilizing historic Isla Del Sol dredging data and other
similar restoration projects to design the project. A
formal engineering company will be hired before work
begins.
- Get bids from approved companies for turnkey project.
- Approved company to turnkey the project to agreed
specifications.
- Complete project between May and September 2006
- Set up a Quarterly Monitoring Plan with Isla Del Sol
property owners under instructions of NOAA personnel.
Restoration methodology:
Project would involve placing 730 meters (2438 linear
feet) of 4.5 meter diameter geotextile fiber tubes
filled with sand. The sand used is dredged material
from the Isla Del Sol Subdivision channel. The sand
filled geotextile tube will be place on the north
shoreline in front of existing marsh.
Measures of Success:
Restore 20 acres of salt marsh and 7 acres
of shallow open water sand flats.
Monitoring and Long-Term Management:
Isla Del Sol Home Owners Association will work with
NOAA to base a monitoring plan on the following book:
“Science Based Restoration Monitoring of Coastal
Habitats”, ref: NOAA Coastal Ocean Program Decision
Analysis Series No. 23, Volume 1.
- Goal- Shoreline Protection and restore 20 acres of
salt marsh area.
- Objective- Protect the existing 15 acre salt marsh
and shoreline, and restore an additional 20 acres of
salt marsh area and 7 acres of shallow water sand
flats.
Community Involvement:
The Isla Del Sol Home Owners in conjunction with the
West
Galveston Island Property Owners Association are both
involved in informing the public about the advantages
of marsh habitat restoration and shoreline protection.
This is handled in public meeting and newsletters from
both organizations. IDSHOA had a NOAA representative at
its last annual meeting (April 2004) to gives the
members a presentation on marshland restoration and its
importance to the bay ecosystem. Plans are to continue
this educational process at each annual meeting and
have a section of our Newsletter devoted to education.
The Isla newsletter comes out 2 – 3 times per year and
will be place on our website.
