The plan was developed to assist the American Samoa Environmental Protection Agency (ASEPA) with the implementation of earlier recommendations presented in its regional Watershed Protection Plan.  The plan was primarily to evaluate potential opportunities and develop conceptual site plans for:

• stormwater detention that could help improve nearshore water quality; and,
• conservation of fish, wildlife, and unique vegetation.

Pedersen Planning Consultants (PPC) initially performed field surveys of approximately 10 wetlands and five riparian areas that were selected by ASEPA.  These surveys delineated wetland boundaries, documented existing fish, wildlife, and vegetative resources, and located long-term resource monitoring stations.  The survey used a combination of global positioning system (GPS) and geographical information system (GIS) technologies to integrate update digital files and establish new databases for long-term resource management.  Potential stormwater detention opportunities were documented.  Specific opportunities for the conservation of fish, wildlife, and unique vegetation were also identified.  A digital photo library was established for all sites to facilitate long-term comparisons of wetland and riparian conditions.

Potential stormwater detention opportunities were further evaluated through the modeling of 2,10,50, and 100-year storm events.  Conceptual site plans were prepared which depicted proposed improvements for achieving greater stormwater detention in selected wetlands. 

Similarly, conceptual site plans also outlined recommended conservation sites.  These conservation sites included opportunities for the replanting of vegetation that would foster improved stream hydrology and/or increase fish and wildlife habitat.  Other conservation proposals included potential recreational opportunities that would promote increased public education and appreciation for wetland and riparian areas.  The preservation of selected sites was also given consideration where unique vegetative, fish and wildlife resources were identified.
