Port of Oakland International Airport, Oakland, California
This project involved over 2,600 acres of land with 640 acres of jurisdictional wetlands delineated in past field projects. Wetland delineations performed over the years have resulted in widely varying estimates of Corps jurisdiction on the Airport property. The purpose of this study was to reduce the level of uncertainty as to what areas were and were not wetlands so that future development planning and day-to-day operations could be implemented with less uncertainty as to treatment and care of areas.
To provide the needed information for the Port and its maintenance staff, the following tasks were performed and reports and maps provided:
- Wetland delineation that included sampling, categorizing and verification of wetland acres
- Hydrologic modeling of wetland areas to determine if they met the Corps definition of a wetland (2-year event)
- Wetland functional assessment including food chain productivity, threatened and endangered species, shoreline protection and sediment control, groundwater recharge, flood conveyance and storage, hydrologic support, water quality, cultural values, biogeochemical cycles and atmospheric processes
- Stormwater Management Plan with recommendations for an improved drainage system and techniques for facility maintenance personnel
- Vegetation Management Plan to establish operational criteria and provide specific operational techniques/guidelines for vegetation management, low-lying areas and/or eradication of noxious weeds in wetlands
- Wetlands Management Plan to identify specific management techniques in existing wetlands and specific recommendations to avoid creating new wetlands adjacent to existing wetlands. Recommendations were made to drain wetland areas created by above normal rainfall conditions. Operational criteria was provided along with techniques and guidance for facilities maintenance personnel to inhibit new wetlands from forming due to surface water flooding and ponding
- All information was incorporated into electronic maps in AutoCAD 14. This was linked to an Oracle table and to Acad Mapguide. Wetland function and value data and index values were digitally formatted and the data lined by ESS Connect for use on PORT CAD and GIS System using Oracle and Mapguide
