Incorporation Of Detailed, New Jersey Specific Hydrologic Information Into The Wetland Construction And Mitigation Planning Process - Review of wetland construction design Completed
New Jersey WSC Archived Projects
The NJDEP is responsible for the review of proposals for wetlands mitigation and restoration submitted to the Wetland Mitigation Council. They have expressed concern that the failure of various wetland mitigation projects may be a result of problems with the hydrology of the sites. The goal of this project is to Assess the extent of hydrologic data and information that are used in typical wetland construction/mitigation designs and to formulate a supplement to existing wetland construction design manuals.
START DATE: 20-AUG-2003
END DATE: Not specified
PROJECT NUMBER: 2454B2F
STUDY OBJECTIVES:
- Assess the extent of hydrologic data and information that are used in typical wetland construction/mitigation designs, and provide review information to NJDEP/WMC.
- Formulate a supplement to existing wetland construction design manuals to aid in the incorporation of New Jersey specific hydrologic data into the design process.
STATEMENT OF PROBLEM:
The NJDEP is responsible for the review of proposals for wetlands mitigation and restoration submitted to the Wetland Mitigation Council. They have expressed concern that the failure of various wetland mitigation projects may be a result of problems with the hydrology of the sites. Successful wetland design, construction, and maintenance are predicated on the ability of the local hydrologic system to permanently sustain the wetlands. Constructed wetland failures have result from the use of improper hydrologic data or assumptions in the design process, particularly with regard to the use of data appropriate for New Jersey Conditions. The USGS has collected, processed and maintains data on the water resources of New Jersey. Today the NJ district collects data from an integrated statewide network that includes streamflow gaging sites, groundwater-level monitoring sites and weather monitoring sites. Additionally, the USGS collects specific onsite water resource data as part of numerous water resource investigations completed in New Jersey. This and information available from related agencies needs to be made available to those parties undertaking wetland design.
STRATEGY AND APPROACH:
- Review hydrologic data and information for proposed or existing wetland restoration sites (5 sites)
- Analyze existing USGS data and compare to project data.
- Prepare letter report to DEP on results of analysis with recommendations on the adequacy of the water budget for the project.
- Provide recommendations on monitoring hydrologic parameters
- Work with DEP staff as needed throughout the review process
