Coastal Infrastructure Design, Construction and Maintenance (CDCM)

• Designed to reduce long-term vulnerability of coastal infrastructure through expanded capacity for appropriate design, construction and maintenance

• Part of USAID’s Caribbean Regional Program (Kingston Jamaica) response to Hurricane Lenny

• Executed by the OAS and implemented by the Engineering Institute of the University of the West Indies (Trinidad campus), in conjunction with Old Dominion University and the Army Corps of Engineers’ Coastal Hydrology Laboratory


CDCM Training Program:Needs Assessment

• Regional coastal engineering needs assessment undertaken to establish baseline, guide project design

• Findings:→Coastal zone management planning limited→Need for sound data collection and analysis procedures→EIA currently used, application should be expanded→Coastal infrastructure design standards need improvement→Inspection and maintenance of coastal infrastructure lacking→Good materials lab and quarries available in the region→Good pool of contractors available in the region, but

specialized training is needed.


CDCM Training Program:Training Courses

Target Audience: Engineers, Planners152 training opportunities, core of ~25 participants

Courses: June-September 2001• Coastal Zone Management, Antigua and Barbuda (June) and St.

Lucia (July)• Coastal Defense Systems: Part I, St. Lucia (July), and Part II,

Dominica (Aug)• Monitoring and Maintenance, Grenada (Sept)• Design of Marine Structures, Trinidad and Tobago (Sept)

USACE’s Coastal Engineering Manual used extensively


Hurricane Hazard Information for Caribbean Coastal Construction

Web-based application to provide access to regional, return-period based storm hazard information

• Map-based interface

• User selects return period, projection limit

• Point and click report generation

• Information on storm surge, wind and wave hazards

CDCM Training Program: Recommendations

Expand the building of expertise, institutional capacity:• academic capacity for coastal engineering at UWI• design, implement follow-on training program• organize annual Caribbean coastal management conference• develop web-based network linking academic and specialized

institutions with coastal engineers, managers

Develop regional tools for data management, analysis:• Promote use of coastal resources inventory system (CRIS)• regional-scale advanced coastal processes modeling• maintain/improve climate, sea level, beach monitoring networks• production of and access to new bathymetric data


CDCM Training Program: Recommendations (cont’d)

Assist development of national implementation plans:• update CRIS, national GIS with recent coastal information• identify critical and at-risk locations, develop monitoring

strategies• develop and implement (as pilot) an island coastal management

plan, disseminate results in region

Bring the problem of inadequate design and construction to the attention of the political and civil society leadership


Where could the national economy have beenif this had not failed?
