Reports on this web page are organized by their WSDOT region. To find out which WSDOT region your county is located in, view the WSDOT Regions Map (pdf 932 kb).

Five types of reports are listed on this web page:

  • Hydraulic Project Approval (HPA) Monitoring Reports are letter-format reports for compliance with HPA permits from the Washington State Department of Fish and Wildlife.
  • Off Year Monitoring Reports- Reports required by permits that do not follow the reporting and monitoring timeline required by the Mitigation Report.
  • Stream Monitoring Reports are similar to wetland reports, but discuss stream mitigation sites.
  • Wetland Monitoring Reports are full length reports discussing the development of individual wetland mitigation sites for federal, state and local permit compliance. Wetland monitoring reports are written for the years specified by these permits using quantitative data.
  • Mitigation Bank Monitoring Reports are full length reports discussing the development of mitigation banks for compliance with the Mitigation Bank Instrument (MBI). Bank monitoring reports are written for the years specified in the MBI using quantitative data..

All reports for 2013 through 2012 are listed below.
