North Parcel Seasonal Wetlands Enhancement

Project Description:  

This project involved the planning, design, plans and specifications, bid management, construction oversight, permitting, and monitoring of a 320-acre seasonal wetland enhancement project in northern San Francisco Bay on diked agricultural baylands. 


WWR carried out background studies including: wetland delineation, hydrology, topography, and soils. The WWR design utilized an innovative shallow groundwater management strategy. Project construction took place in fall 2003. WWR is currently implementing a five-year monitoring program. 


This project involved field investigations including installation and monitoring of shallow groundwater piezometers, installation of surface water level monitoring stations, installation of rainfall gauges, extensive topographic mapping through aerial photogrammetry and ground-based total station instruments, botanical surveys in support of wetland delineation, and wildlife surveys in support of permits. 


We used Geographic Information System (GIS) tools to support project design and alternatives evaluation and to evaluate watershed water supply contributions.
