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
